We investigate the tight-binding approximation for the dispersion of the $\ensuremath{\pi}$ and ${\ensuremath{\pi}}^{*}$ electronic bands in graphene and carbon nanotubes. The nearest-neighbor tight-binding approximation with a fixed ${\ensuremath{\gamma}}_{0}$ applies only to a very limited range of wave vectors. We derive an analytic expression for the tight-binding dispersion including up to third-nearest neighbors. Interaction with more distant neighbors qualitatively improves the tight-binding picture, as we show for graphene and three selected carbon nanotubes.

QU EST IONS have been raised concerning the relationship between the U.S. Military Assistance Program in Latin America and the role of the military in Latin American politics ever since the passage of the Mutual Security Act of 1951. Some critics have directly equated this program (MAP) with the ability of the military in Latin America to conduct political interventions." Recent events in Latin America have re-kindled this concern: in 1961, the Brazilian military, in an indirect but significant intervention, altered the constitutional form of the Brazilian government; in 1962, the military directly intervened in the electoral processes of Argentina and Peru; Ecuador has experienced a prolonged period of intermittent military interventions in its political life; and the year 1963 will go down in history as one marked by continued military participation in the politics of Argentina and Peru, and outright military coups d'etat in Guatemala, the Dominican Republican, and Honduras. American displeasure at such military takeovers has been ineffectively expressed in a delayed recognition policy which does credit neither to the maturity of American diplomacy nor to the complexities involved in such political disturbances. There is no factor now operating in the Latin American political equation which shows promise of altering the conditions under which such activities occur, and additional military interventions can be expected in the future. The concern aroused by the present course of civil-military relations in many Latin American countries, combined with a pronounced shift in the nature of the MAP under the Kennedy administration, makes this an opportune time to examine some of the fundamental questions concerning military assistance and militarism in Latin America. Prior to Fiscal Year 1962, U.S. military assistance to Latin America was based on the idea of hemispheric defense against external aggression. A review of this concept by the newly installed Kennedy Administration led to the conviction that only selected anti-submarine warfare units could contribute significantly to hemispheric defense in case of a large-scale conflict, and that emphasis should be shifted toward internal security and counterinsurgency capabilities. Further, recognizing the danger of exposing the United States to charges that it supports military dictatorships, or encourages the military to suppress the very social and political changes that the U.S. urges under Alliance for Progress, the Kennedy Administration gave increased emphasis to Civic Action Programs in Latin America." Attempts were made to

Background: Studies have shown that mini-αA can protect retinal pigment epithelium (RPE) cells from apoptosis. However, no in vivo study concerning the anti-apoptotic function of mini-αA has been conducted yet. Methods: MTT assay, HE staining and TUNEL assay were used to assess levels of cells, and an animal model was established to examine the protective effects of mini-αA against NaIO3-induced RPE cell apoptosis. Western blot analysis and RT-qPCR were performed to explore the possible mechanism of mini-αA’s protective function against NaIO3-induced RPE cell apoptosis. Results: Results from in vivo and animal experiments showed that mini-αA antagonized NaIO3-induced RPE cell apoptosis. Further investigation into how mini-αA provided protection against NaIO3-induced RPE cell apoptosis showed that mini-αA reduced NaIO3-induced RPE cell apoptosis and autophagy. In addition, unfolded protein response was also involved in the protective effects of mini-αA against NaIO3-induced RPE cell apoptosis. Conclusions: mini-αA can antagonize RPE cell apoptosis induced by NaIO3. A possible mechanism is by inhibition of apoptosis by repressing autophagy and endoplasmic reticulum stress.

School of Interdisciplinary Bioscience and Bioengineering, POSTECH, Pohang 790-784, Republic Korea(2014년 7월 2일 접수, 2014년 7월 8일 채택)AbstractMacroalgae has been strongly touted as an alternative biomass for biofuel production due to its higher photosynthetic efficiency, carbon fixation rate, and growth rate compared to conventional cellulosic plants. However, its unique carbohydrate composition and structure limits the utilization efficiency by conventional microorganisms, resulting in reduced growth rates and lower productivity. Nevertheless, recent studies have shown that it is possible to enable micro-organisms to utilize various sugars from seaweeds and to produce some energy chemicals such as methane, ethanol, etc. This paper introduces the basic information on macroalgae and the overall conversion process from harvest to production of biofuels. Especially, we will review the successful efforts on microbial engineering through metabolic engineering and synthetic biology to utilize carbon sources from red and brown seaweed.

The purpose of this study was to investigate the effect of active recovery on the postexercise pulmonary diffusion capacity (DL) and its two components, alveolar-capillary membrane diffusion capacity (DM) and pulmonary capillary blood volume (Vc). Ten trained non-smoking male cyclists ( age= 22 ± 2 yrs; ht = 177.4 ±7.1 cm; mass = 70.3 ± 9.1 kg; V 0 2 m ax = 61.0 ± 4.4 ml/kg/min) were recruited for this study. All subjects demonstrated normal pulmonary function with no history of respiratory disease. All spirometry and diffusion measurements were administered using the Collins PLUS DS II pulmonary function testing unit. Subjects cycled to exhaustion to determine maximal oxygen consumption (V0 2max ) and ventilatory threshold (VT) on an electronically-braked cycle ergometerin their first visit. In the following two experimental trials labeled active recovery (AR) and inactive recovery (IR), all pulmonary diffusion measurements were performed. In both sessions, pre-exercise baseline values for DLco, DM and Vc were first obtained. Subjects then performed 45 minutes of cycling exercise at the individual's VT with maximal effort near the end. In only the AR trial, subjects performed an additional 30 minutes of cycling at 10% of individual's maximal power output immediately following the 45-minute exercise bout. Two additional pulmonary diffusion capacity measurements were made at 1 and 2 hours following the 45-minute submaximal exercise test. DM and Vc were calculated by measuring DLco at two inspired 0 2 concentrations using the technique of Roughton and Forster (1957).

The present work demonstrates ferroelectric to antiferroelectric transition aided electric field control of positive and negative electrocaloric effects (ECE). In this context, epitaxial PbZrO3 (PZO) thin films were grown on (111) Nb:SrTiO3 single crystal substrates by the sol–gel method, and the epitaxial growth was confirmed by atomic resolution scanning transmission electron microscopy (STEM) high angle annular dark field (HAADF) images. The structural and elemental analysis revealed a gradual increase of natural lead volatilization from the middle to the top in PZO thin films. The electrocaloric effect (ECE) was calculated using Maxwell equations corresponding to 10 kHz and 100 Hz P–E data and was found to be −10.5 K (negative ECE) at 375 K and 30 K (positive ECE) at 300 K. Intriguingly, both negative and positive ECE were found in the same phase transition sequence, that is, from an antiferroelectric phase to a ferroelectric phase. The frequency dependence of ECE is found to be dependent on the polarization switching dynamics and kinetics. These results are not only scientifically important for providing an easy way to combine the negative and positive ECE together to further enhance the cooling efficiency but are also technically important for future ECE devices.

We present a multi-species trace gas sensor based on a broadband mid-infrared supercontinuum source and a compact home-built Fourier Transform Spectrometer with a balanced detection scheme. The gas sensor provides a spectral resolution of 1 GHz in the wavelength range of 2.4-4.2 µm. Using a global fitting routine, we are able to retrieve the concentrations of different species in complex gas mixtures, achieving detection sensitivities in the order of 100 ppbv.Hz-1/2 (4s measurement time). We used the sensor to measure volatiles from fruit (apples, pears) under storage conditions, demonstrating its potential for monitoring fruit in commercial storage facilities.

To assess the different types of health disorders that are more frequent during the pregnancy and drugs prescribed for the management of those disorders are of the safest category and in practice considering the risk to benefit ratio. Also, to find out the extent to which the drugs prescribed are adhered to WHO prescribing indicators. It was an observational crosssectional study. Data collection sheets were filled by the direct questionnaire and the prescription paper. The drugs were evaluated from WHO core prescribing indicators. Among the total of 141 pregnant women, the maximum number were from the age group 20-25 years. The average number of drugs received during pregnancy is 3.25 per prescription. Whereas the percentage of the drug prescribed by generic name and essential drug list were found to be 26.1 and 56.64, respectively. The most frequently prescribed drug was from the USFDA safe category i.e. category B (53%) and only 2% of drugs were prescribed from category X. Most of the medicine was prescribed listed in the National essential drug list. Deviation was observed in terms of prescription of injection and drugs with a generic name. Contraindicated medicines during pregnancy were almost absent in this study. Pregnant women who appeared during the duration of the study with the health disorder were treated with the appropriate drugs considering the risk to the benefit ratio. However, to assure the rational drug prescription the prescription audit should be carried out at regular intervals.

The development of the embryonic lung demands complex endodermal–mesodermal interactions, which are regulated by a variety of signaling proteins. Hedgehog (Hh) signaling is vital for lung development. It plays a key regulatory role during several morphogenic mechanisms, such as cell growth, differentiation, migration, and persistence of cells. On the other hand, abnormal expression or loss of regulation of Hh signaling leads to airway asthmatic remodeling, which is characterized by cellular matrix modification in the respiratory system, goblet cell hyperplasia, deposition of collagen, epithelial cell apoptosis, proliferation, and activation of fibroblasts. Hh also targets some of the pathogens and seems to have a significant function in tissue repairment and immune-related disorders. Similarly, aberrant Hh signaling expression is critically associated with the etiology of a variety of other airway lung diseases, mainly, bronchial or tissue fibrosis, lung cancer, and pulmonary arterial hypertension, suggesting that controlled regulation of Hh signaling is crucial to retain healthy lung functioning. Moreover, shreds of evidence imply that the Hh signaling pathway links to lung organogenesis and asthmatic airway remodeling. Here, we compiled all up-to-date investigations linked with the role of Hh signaling in the development of lungs as well as the attribution of Hh signaling in impairment of lung expansion, airway remodeling, and immune response. In addition, we included all current investigational and therapeutic approaches to treat airway asthmatic remodeling and immune system pathway diseases.

Selective attention implements preferential routing of attended stimuli, likely through increasing the influence of the respective synaptic inputs on higher-area neurons. As the inputs of competing stimuli converge onto postsynaptic neurons, presynaptic circuits might offer the best target for attentional top-down influences. If those influences enabled presynaptic circuits to selectively entrain postsynaptic neurons, this might lead to selective routing. Indeed, when two visual stimuli induce two gamma rhythms in V1, only the gamma induced by the attended stimulus entrains gamma in V4. Here, we modeled this selective entrainment with a Dynamic Causal Model for Cross-Spectral Densities and found that it can be explained by attentional modulation of intrinsic V1 connections. Specifically, local inhibition was decreased in the granular input layer and increased in the supragranular output layer of the V1 circuit that processed the attended stimulus. Thus, presynaptic attentional influences and ensuing entrainment were sufficient to mediate selective routing.

INTRODUCTION
Acute pain and chronic pain are significant burdens in the Department of Defense, compounded by the ongoing opioid crisis. Given the ubiquity of (leftover) opioid prescriptions following orthopedic surgery, it is essential to identify feasible and acceptable avenues of opioid risk mitigation efforts. The present quality improvement project builds on recent studies by evaluating factors related to opioid prescribing decisions in a sample of orthopedic surgery providers.
MATERIALS AND METHODS
This quality improvement project received a Determination of Not Research and was conducted through a collaboration between the Department of Orthopaedic Surgery and the Department of Anesthesiology and Pain Management at Walter Reed National Military Medical Center. Providers in the Department of Orthopaedic Surgery completed an anonymous online survey assessing opioid prescribing education, factors influencing prescribing practices, opioid-safety practices, and perspectives on potential opioid safety initiatives.
RESULTS
In total, 39 respondents completed surveys. There was variability in exposure to different types of opioid prescribing education, with some variation between attendings/physician assistants and residents. Patients' acute postsurgical pain, using a standardized amount for most patients, and prescription histories were the three most influential factors. Concern of patients running out and fear of patient dissatisfaction were the least influential factors. Respondents commonly reported engagement in promoting nonpharmacological pain management, as well as coordinating with chronic pain providers when applicable, but did not commonly report educating patients on leftover opioid disposal. Respondents indicated that a barrier to opioid risk mitigation was the difficulty of accessing appropriate electronic health record data to inform decisions. Lastly, they reported openness to proposed opioid safety initiatives.
CONCLUSION
The results of this quality improvement project identified several target areas for future initiatives focused on improving opioid prescribing practices. This included a provider training program, improved patient education system, increased awareness and use of opioid tracking databases, and development of a standardized (but adaptable per patient characteristics and history) recommended dose for common orthopedic surgeries. Future projects will target tailored development, implementation, and evaluation of such efforts.

We apply a notion of static renormalization to the preparation of entangled states for quantum computing, exploiting ideas from percolation theory. Such a strategy yields a novel way to cope with the randomness of nondeterministic quantum gates. This is most relevant in the context of optical architectures, where probabilistic gates are common, and cold atoms in optical lattices, where hole defects occur. We demonstrate how to efficiently construct cluster states without the need for rerouting, thereby avoiding a massive amount of conditional dynamics; we furthermore show that except for a single layer of gates during the preparation, all subsequent operations can be shifted to the final adapted single-qubit measurements. Remarkably, cluster state preparation is achieved using essentially the same scaling in resources as if deterministic gates were available.

<p>Hyporheic exchange represents the interactions between surface and subsurface flows occurring at various geophysical scales. Its importance to the riverine ecological health and the fate of contaminants has long been recognized. Traditionally, the behaviors of hyporheic exchange are explained by the emergence of geomorphological features, such as dune-shaped bedforms, that usually introduce significant pressure differences along the channel bed and, therefore, facilitate exchanges by pumping the flow inward and outward the bed. In addition to this advective mechanism, near-bed turbulence has also been identified as another driver of flow exchange through the turbulent diffusive processes. This study, on the other hand, highlights the decisive control of surface waves on the hyporheic exchange at depth-limited flow conditions, especially for those unbroken standing waves commonly encountered in river riffle areas. It is hypothesized that the presence of surface waves will reshape the distribution of near-bed hydrodynamic pressures, thus altering the properties of advective flows along the channel bed. The validity of this hypothesis is carefully examined through the laboratory experiments using Refractive-Index-Matched (RIM) liquid and solid materials and Particle Tracking Velocimetry (PTV) techniques. This experimental setting helps to simultaneously resolve the surface and subsurface flow patterns to a sufficient detail; the hydrodynamic pressure field can then be derived from the obtained flow velocity fields. Further analysis in a Double-Averaged Navier-Stokes framework indicates that, among different contributing factors, pressure gradient is found to be the most dominant driver of interface exchange. The variations of this driving mechanism, interestingly, can be further decomposed into two parts, namely, the surface wave associated (global-scale) and the bed grain associated (local-scale) components, respectively.</p>

COVID-19 outbreak impacts the fluctuation of medical kit in Indonesia and around the world. When everyone is trying to donor the relief, without knowing the real demand, it could be oversupplied. Furthermore, when this pandemic ends, the relief could be useless. The humanitarian supply chain has a role in ensuring the flow of relief aid and providing effective and efficient related information . The use of Pareto analysis could help finding what are the most needed items in handling disaster. In this paper, the researchers are trying to find if there is inefficiency in distributing the relief to the beneficiary by calculating the percentage of received and distributed relief aid to avoid overstock or out-of-stock case. Moreover, the researchers also look for possibilities of distribution efficiency.

This paper presents a PhD-course called "Kick start to academic life - Information Management and Publication Process for Social Scientists", a collaboration between the Social Sciences Faculty Library at Lund University and professors at the Faculty. The objective of the course is to provide PhD candidates with generic knowledge about how to effectively conduct their PhD studies when it comes to information management and the publication processes. The course combines an introduction to the process of managing one's need of information as a PhD student, and an introduction to the process of managing the publication of one's results. The librarians have been involved in the development of this PhD course, from the first idea of a course in generic competences and on to the actual implementation. The Faculty of Social Science came up with the idea of a course like this in 2009, and asked two teachers/professors and two librarians to make an outline. We choose to focus on students in the beginning of their PhD studies, who would benefit most from it. We have now run it for 3 years (2010-2012), developed the course as for content and size, from demands from students and faculty as well as from our own experiences. Designing the course together, librarians and professors gained an insight into each other's competences and area of expertise. We used previous experiences from working with PhD students, like the providing of shorter courses, seminars and workshops. We choose a course design mixing lectures and workshops, in order to make the course both theoretical and practical. The course design also helped emphasizing aspects of the subject being discussed. One example is by adding a practical workshop in reference management program given by the librarians just after a lecture given by a professor about how and why academics cite. Another example is when we invite an editor of a high ranked peer-reviewed journal to talk about article submission from the journals/editors point of view and then follow up with a more practical session on where, how and what kind of information you search in order to find relevant information about possible journals to send manuscripts to. This course design creates dynamic connections between the more classic way of academic lectures/discussions and tools that improve the PhD students' generic skills. As a result, valuable connections are being made and it is also a way of visualizing how academia works and how the culture is communicated in different ways. This includes everything from demystifying the "back-stage processes" of academia as well as finding relevant tools to navigate in a rapidly changing publication process. Both workshops and home assignments are built upon the idea of constructive alignment. The students are to focus on their respective subject field when working with the assignments, to make them matter to the individual.

This research was conducted to find out the financing opportunities of home ownership financing for Islamic banks through Sharia Asset Backed Securities-Participation Letters (EBAS-SP) in Indonesia. EBAS-SP are asset backed securities that have a portfolio in the form of a participation letter for secondary home ownership financing that has a system that is in accordance with Islamic Sharia so that in each issuance process the securities must obtain a statement of Sharia principle conformity from the expert team Sharia capital market and Sharia Supervisory Board. This study uses the Analytic Hierarchy Process (AHP) approach, following the priority of the strategy as a solution that can be offered. The results of this study indicate that: First, there are 4 issues of issues in developing the ability to mitigate the risk of home ownership financing for Islamic banks in Indonesia through the asset-backed effect of Islamic assets-participation letters, including legal / structural issues, sharia issues, operational issues and human resource issues. Second; For priority issues in terms of the use of Sharia Asset Backed Securities instruments and Participation Letters in the AHP Method frame according to the agreement of Experts, Practitioners, Academics and Regulators are operational aspects and aspects of human resources (HR). Third; the results of this study also show a picture of a solution in the strategy of increasing risk mitigation in PPR products through EBAS-SP for all four issues. And finally, the priority solution in solving problems based on expert agreement is the solution in legal / structural aspects, sharia aspects and operational aspects. So that the risk of home ownership financing mitigation using securities-backed securitization instruments can be a solution for home ownership financing for the community. Because EBAS takes the form of a participation letter supported by liquid assets and has a relatively small risk.

Parton-model predictions for lepton-pair production from polarized spin-1/2 particles are considered within the context of a formalism explained in a companion paper. The polarization effects in the quantum-chromodynamic 2 {yields} 2 subprocesses which contribute to lepton-pair production are found to be quite simple. Following the work of Ralston and Soper, polarized distribution functions are defined for gluons as well as quarks. Finally, a detailed discussion of polarization and the hard-scattering formalism is presented for the two cases of intrinsic parton transverse momentum allowed or forbidden.

The conformation and membrane topology of the disulfide-stabilized antimicrobial peptide tachyplesin I (TP) in lipid bilayers are determined by solid-state NMR spectroscopy. The backbone (phi and psi) torsion angles of Val(6) are found to be -133 degrees and 142 degrees , respectively, and the Val(6) CO-Phe(8) H(N) distance is 4.6 A. These constrain the middle of the N-terminal strand to a relatively ideal antiparallel beta-sheet conformation. In contrast, the phi angle of Gly(10) is +/-85 degrees , consistent with a beta-turn conformation. Thus, TP adopts a beta-hairpin conformation with straight strands, similar to its structure in aqueous solution but different from a recently reported structure in DPC micelles where bending of the two beta-strands was observed. The Val(6) and Gly(10) CO groups are both 6.8 A from the lipid (31)P, while the Val(6) side chain is in (1)H spin diffusion contact with the lipid acyl chains. These results suggest that TP is immersed in the glycerol backbone region of the membrane and is oriented roughly parallel to the plane of the membrane. This depth of insertion and orientation differs from those of the analogous beta-sheet antimicrobial peptide protegrin-1 and suggest the importance of structural amphiphilicity in determining the location and orientation of membrane peptides in lipid bilayers.

The low-lying electric dipole ($E1$) strength in the semimagic nucleus ${}^{136}$Xe has been measured, which finalizes the systematic survey to investigate the so-called pygmy dipole resonance (PDR) in all stable even $N=82$ isotones with the method of nuclear resonance fluorescence using real photons in the entrance channel. In all cases, a fragmented resonance-like structure of $E1$ strength is observed in the energy region 5--8 MeV. An analysis of the fragmentation of the strength reveals that the degree of fragmentation decreases toward the proton-deficient isotones, while the total integrated strength increases, indicating a dependence of the total strength on the neutron-to-proton ratio. The experimental results are compared to microscopic calculations within the quasiparticle phonon model. The calculation includes complex configurations of up to three phonons and is able to reproduce also the fragmentation of the $E1$ strength, which allows us to draw conclusions on the damping of the PDR. Calculations and experimental data are in good agreement on the degree of fragmentation and also on the integrated strength if the sensitivity limit of the experiments is taken into account.

AIMS
The present study investigated the effect of the newly synthesized cannabinoid CB(1) receptor antagonist, SR147778, on alcohol intake and the motivational properties of alcohol in selectively bred Sardinian alcohol-preferring (sP) rats.
METHODS AND RESULTS
In Experiment 1, the repeated administration of SR147778 (0.3-3 mg/kg twice daily, i.p.) specifically suppressed the acquisition of alcohol drinking behaviour in alcohol-naive rats exposed to the two-bottle "alcohol vs water" choice regimen for 24 h/day. In Experiment 2, an acute administration of SR147778 (2.5-10 mg/kg, i.p.) specifically reduced alcohol intake in alcohol-experienced rats that were given alcohol and water under the two-bottle choice regimen in daily sessions of 4 h. In Experiment 3, an acute administration of SR147778 (0.3-3 mg/kg, i.p.) suppressed the "alcohol deprivation effect", i.e. the extra-intake of alcohol occurring after a period of alcohol abstinence. In Experiment 4, an acute administration of SR147778 (0.3-3 mg/kg, i.p.) specifically suppressed the extinction responding for alcohol, i.e. the maximal number of lever responses reached in the absence of alcohol in rats trained to lever-press for alcohol (measure of the motivational properties of alcohol). In Experiment 5, the combination of 3 mg/kg of SR147778 (i.p.) and 0.5 g/kg of alcohol (i.p.), a dose comparable with those usually consumed by sP rats in each drinking binge, failed to induce any conditioned taste aversion.
CONCLUSION
Taken together, these results extend to SR147778 the anti-alcohol profile of the prototype cannabinoid CB(1) receptor antagonist, rimonabant (SR141716), and strengthen the hypothesis that the cannabinoid CB(1) receptor is part of the neural substrate mediating alcohol intake and the motivational properties of alcohol.

Binary Neural Networks (BNNs) can drastically reduce memory size and accesses by applying bit-wise operations instead of standard arithmetic operations. Therefore it could significantly improve the efficiency and lower the energy consumption at runtime, which enables the application of state-of-the-art deep learning models on low power devices. BMXNet is an open-source BNN library based on MXNet, which supports both XNOR-Networks and Quantized Neural Networks. The developed BNN layers can be seamlessly applied with other standard library components and work in both GPU and CPU mode. BMXNet is maintained and developed by the multimedia research group at Hasso Plattner Institute and released under Apache license. Extensive experiments validate the efficiency and effectiveness of our implementation. The BMXNet library, several sample projects, and a collection of pre-trained binary deep models are available for download at https://github.com/hpi-xnor.

The redesign of primary care through the patient-centered medical home offers an opportunity to assess the role of primary care in treating mental health relative to the rest of the health care system. Better understanding the patterns of care between primary care and mental health providers helps guide necessary policy changes. This article reports the findings from 109,593 respondents to the 2002-2009 Medical Expenditure Panel Surveys (MEPS). We examined the extent to which persons with poor mental health visited primary care providers, and distinguished among 4 patterns of care: (a) mental health only, (b) primary care only, (c) dual care (both mental health and primary care) and (d) other provider combinations. Our findings indicate that poor mental health and specific mental health conditions remain prevalent in primary care. An increased focus on patient-centered care requires greater integration of primary and mental health care to reduce fragmentation of care and disparities in health outcomes.

Gettier's examples show that someone can believe a truth, have good reasons for believing it, and yet lack knowledge.1 How can this be? One explanation is that a man's good reasons can depend upon or include false beliefs. Another possibility is that a justified true belief can fail to stand in an appropriate causal relation to the fact which makes the belief true. Both explanations fit Gettier's examples, but perhaps neither is sufficiently general: each assumes, as indeed Gettier's exposition does, that someone is adequately justified or not in virtue of evidence he actually has for a truth. Might not a man's good reasons be said to be defeated, undermined, or rendered inadequate, by further evidence he would, but happens not to, take into account? This is the possibility adverted to by certain defeasibilist analyses of knowledge and nonknowledge. Such analyses grant that Gettier's subjects are justified in believing a truth, but they explain in a distinctively general way the fact that those subjects lack knowledge. The lack ensues from incomplete justification. If someone's actual justification for a true belief admits of supplementation or correction that would disclose evidence against the belief, then one's actual basis for believing is incomplete. Conversely, if correction or supplementation were not to detract from one's reasons, one is actually completely justified, and one's true belief is knowledge-ranking. In Gettier's cases, conditions of complete justification fail to be met. But complete justification might be absent, too, where one's reasons involved no falsehoods, and where one's true belief was non-deviantly caused. In those circumstances it could still turn out that exposure to further evidence would warrant the retraction of some actually held true belief. Defeasibilism thus seems to alert us to, and to account for, cases of non-knowledge that Gettier did not prepare us for.

Cancer immunotherapy has become a powerful treatment option for a wide range of cancers. The goal of most cancer immunotherapies is to activate cancer-specific T lymphocytes that can recognize and kill tumor cells expressing tumors-specific antigens. Examples of these tumor-antigens are viral antigens, mutated antigens, and overexpressed self-antigens. Since central tolerance is exclusively induced for self-antigens in the thymus, mutated (neo-)antigens and viral antigens are ideal targets for therapeutic cancer vaccination.
Human Papilloma Virus (HPV) is an example of a virus that is clearly associated with several cancers, the most frequent of which are cervical cancer and oropharyngeal cancer. HPV has two oncogenes (E6 and E7) that are critical for the induction and maintenance of the transformed cell stage and are constitutively expressed by the cancer cells, making them ideal targets for therapeutic vaccination. Our vaccination approach involves immunization with overlapping synthetic long peptides (SLP) of the oncogenes E6 and E7. This vaccination strategy induces potent T cell responses associated with complete regressions of tumors in mice, and in patients with premalignant lesions [1]. However, in patients with advanced and recurrent tumors, the immune response to the vaccine is much weaker and not inducing a clinical effect. This raised the question how this vaccination could be improved.
In a preclinical mouse model for HPV-induced cancers we tested for seven clinically relevant chemotherapeutics whether they could be combined with SLP vaccination [2]. Importantly, none of the tested chemotherapeutics impaired the immune response to SLP vaccination, and four of them significantly improved vaccination-related survival. The combination of the DNA cross-linking agent cisplatin and SLP vaccination most effectively improved long term survival. In depth analysis of this synergy revealed that HPV-specific CD8 T cells were crucial for the observed synergy. Analysis of the vaccine-induced tumor-infiltrating CD8 T cells showed that a large proportion of these cells produced interferon-gamma (IFN-γ) as well as tumor necrosis factor α (TNFα) upon recognition of HPV antigen. Furthermore, the tumors of mice treated with both cisplatin and peptide vaccination contained lower numbers of proliferating tumor cells and an increased number of apoptotic tumor cells compared to untreated or single agent treated tumors. Notably, we found that a combined effect of TNFα and cisplatin causes enhanced apoptosis of the tumor cells. Neutralization of TNFα by monoclonal antibody injection of mice treated with cisplatin and SLP vaccination resulted in a decreased overall survival when compared to control mice. Together, these data indicate that TNFα is critical for the synergy between vaccination and cisplatin treatment [2].
TNFα is an important member of the “TNF superfamily”, a group of molecules that each bind to their corresponding ligands, all members of the “TNF receptor superfamily”. Triggering of the receptors can result in either activation and proliferation or apoptosis of the target cell. For example, TNFα is involved in the activation of macrophages and endothelial cells, the development of tumors but also in tumor cell death. The coordinated action between TNFα and chemo-therapeutics is in itself not unexpected. Other members of the TNF family synergize with various chemo-therapeutics to cause tumor cell death. Additionally, TNFα itself is strongly associated with cisplatin induced nephrotoxicity [3], and the combination of doxorubicin or melphalan and TNFα in isolated limb perfusion can be extremely efficient as well [4]. However, the serious side effects of systemic treatment with TNFα limit its clinical use and intratumoral administration remains challenging [5]. Importantly, our data indicate that T cells – systemically induced by vaccination - can travel into tumors and locally produce enough TNFα in close proximity to tumor cells to synergize with cisplatin. This not only overcomes the need for the maximum tolerated dose of cisplatin but also avoids the toxic effects of systemic TNFα but still permits the cooperation between TNFα and cisplatin (Figure (Figure11).

Coordinated action of combined treatment with chemotherapy and vaccination
These data are of particular interest for the field of cancer immunotherapy. Recent studies have shown that neo-antigen-specific T cells can be successfully mobilized by vaccination with long peptides, and that these T cells are capable of producing pro-inflammatory cytokines [6;7]. These data indicate that cancer treatment via peptide vaccination could be broadly applied, and might provide clinical benefit in many more cancer types. Checkpoint blockade therapy such as delivery of monoclonal antibodies against PD-1 and CTLA-4 can also enhance the number of TNFα producing intratumoral T cells [7]. Together these data indicate that enhancement of intratumoral TNFα levels via T cell based immunotherapy is feasible and attractive via different methods. The combination of various T cell based immunotherapies with cisplatin might boost the anti-tumor responses via mechanisms dependent on the interaction between TNFα and cisplatin. It will be of interest to explore whether this is indeed what happens when different T cell-based immunotherapies are combined clinically with cisplatin.

The number of physical paths in a carry save or modified Booth multiplier, as well as in a non-restoring cellular array divider is prohibitively large for testing all paths for delay faults. Besides, neither all paths are robustly testable nor a basis consisting of SPP-HFRT paths exists. In this paper we present sufficient modifications of the above mentioned circuits so that a basis consisting of SPP-HFRT paths exists. The cardinality of the derived basis is very small. Also, hardware and delay overheads due to the modifications are respectively small and negligible.

In this study, we found that neutralizing antibody responses in COVID-19-convalescent individuals vary in magnitude but are durable and correlate well with receptor binding domain (RBD) Ig binding antibody levels compared to other SARS-CoV-2 antigen responses. In our cohort, higher neutralizing antibody titers are independently and significantly associated with male sex compared to female sex. ABSTRACT The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) has now caused over 2 million deaths worldwide and continues to expand. Currently, much is unknown about functionally neutralizing human antibody responses and durability to SARS-CoV-2 months after infection or the reason for the discrepancy in COVID-19 disease and sex. Using convalescent-phase sera collected from 101 COVID-19-recovered individuals 21 to 212 days after symptom onset with 48 additional longitudinal samples, we measured functionality and durability of serum antibodies. We also evaluated associations of individual demographic and clinical parameters with functional neutralizing antibody responses to COVID-19. We found robust antibody durability out to 6 months, as well as significant positive associations with the magnitude of the neutralizing antibody response and male sex and in individuals with cardiometabolic comorbidities. IMPORTANCE In this study, we found that neutralizing antibody responses in COVID-19-convalescent individuals vary in magnitude but are durable and correlate well with receptor binding domain (RBD) Ig binding antibody levels compared to other SARS-CoV-2 antigen responses. In our cohort, higher neutralizing antibody titers are independently and significantly associated with male sex compared to female sex. We also show for the first time that higher convalescent antibody titers in male donors are associated with increased age and symptom grade. Furthermore, cardiometabolic comorbidities are associated with higher antibody titers independently of sex. Here, we present an in-depth evaluation of serologic, demographic, and clinical correlates of functional antibody responses and durability to SARS-CoV-2 which supports the growing literature on sex discrepancies regarding COVID-19 disease morbidity and mortality, as well as functional neutralizing antibody responses to SARS-CoV-2.

Multi-Chip Power Modules (MCPMs) allow for integration of high power semiconductor devices and control circuitry into one compact package which yields improved reliability and reduced size, cost, and complexity. The layout design process of an MCPM is time consuming and very multidisciplinary, spanning thermal, electrical, and mechanical issues. A software tool is introduced in this paper which allows for a user to draw a `stick figure' of a desired MCPM layout which is transformed into a multi-objective optimization problem by the tool. After optimization, a user can browse a set of results which form a trade-off curve of approximately Pareto optimal thermal and electrical parasitic layout performance.

Vascular diseases of the elderly are a topic of enormous interest in clinical practice, as they have great epidemiological significance and lead to ever-increasing healthcare expenditures. The mechanisms underlying these pathologies have been increasingly characterized over the years. It has emerged that endothelial dysfunction and chronic inflammation play a diriment role among the most relevant pathophysiological mechanisms. As one can easily imagine, various processes occur during aging, and several pathways undergo irreversible alterations that can promote the decline and aberrations that trigger the diseases above. Endothelial dysfunction and aging of circulating and resident cells are the main characteristics of the aged organism; they represent the framework within which an enormous array of molecular abnormalities occur and contribute to accelerating and perpetuating the decline of organs and tissues. Recognizing and detailing each of these dysfunctional pathways is helpful for therapeutic purposes, as it allows one to hypothesize the possibility of tailoring interventions to the damaged mechanism and hypothetically limiting the cascade of events that drive the onset of these diseases. With this paper, we have reviewed the scientific literature, analysing the pathophysiological basis of the vascular diseases of the elderly and pausing to reflect on attempts to interrupt the vicious cycle that connotes the diseases of aging, laying the groundwork for therapeutic reasoning and expanding the field of scientific research by moving from a solid foundation.

In this work, a gamma scattering technique using 137Cs (5mCi) source with the NaI(Tl) detector is arranged to record the scattered photon beam at scattering angle of 1200 for investigating the liquid density. We used standard liquid such as water, H2SO4, HCl, glycerol, HNO3, ethanol and A92 petrol to fit the single scattering peak, multiple scattering, and total counts versus standard liquid densities. The interpolating of the single scattering peak, multiple scattering, and total counts of the testing sample at scattering angle of 1200 is 0.702 g.cm-3, 0.783 g.cm-3, and 0.747 g.cm-3, respectively. The discrepancy of the experiment and true testing density is about 8 %, 3 %, and 2 %, respectively. The result shows that multiple scattering or total counts can be used to propose the density measurement.

Hace escasos cincuenta anos las sociedades latinoamericanas exhibian estructuras mucho mas simples. Durante el ultimo medio siglo casi todos los paises latinoamericanos han experimentado notables procesos de modernizacion, que han generado una intensa diferenciacion de los tejidos sociales. El sector dedicado a la actividad politica ha ganado una relativa autonomia. Una vasta desilusion colectiva parece ser, sin embargo, la consecuencia de estos procesos. La reforma de los poderes del Estado en terminos de rediseno administrativo constituye lamentablemente la ocupacion central de las modernas elites, junto a nuevas practicas de corrupcion. En algunas naciones la transicion de aristocracia tradicional a elite funcional moderna ha significado no solo un descenso, sino un genuino descalabro historico.

This article is intended to explain an analysis of the ineffectiveness of the supervision of Teacher Guidance and Counseling and the negative consequences that can occur on the development of the professional identity of the guidance and counseling teacher and can erode public trust in the profession of guidance and counseling. The analysis is based on the findings of several studies related to the implementation of supervision of the guidance and counseling teacher's performance in three districts in West Java. Analysis is carried out using the integrated supervision perspective. According to this supervision perspective, the ineffectiveness of the implementation of supervision of guidance and counseling teacher performance can have a devastating effect on the development of the teacher's professional guidance and counseling identity itself, and if ignored; without serious and systematic efforts, sooner or later school counselors will lose their professional identity, and if ignored, the guidance and counseling profession will experience a crisis of trust from the wider community, especially users. Based on the results of the analysis, it is recommended that a number of strategic efforts must be made by various parties involved in the effort to organize the supervision model of the performance of relevant and effective guidance and counseling teachers.

Ancient Hindu cult adhered to Vedas for the moral and social code of conduct. The tenets of Vedas were treated as sublime, hence were unquestionable. The roots of code of conduct cemented in Vedic India gradually metamorphosed into unequal power distribution in Hindu society. It led to the evolution of sexual identities, along with the customs and practices which emanated gender inequality in ancient India. Established social diktats and process of social conditioning nurtured the gender roles. The paper attempts to examine the marriage hymns of Atharva-veda which delineate roles and responsibilities of men and women in the institution of marriage. The analysis is focused on filtered marriage hymns which discuss the concept of Streedhan, prove the existence of patrilocal and patrilineal society, and advocates motherhood. The objective of the paper is to foresee the impact of the Hindu jurisprudence on its women.

ABSTRACT Introduction: Addressing the reservoir of Latent Tuberculosis Infection (LTBI) is critical to TB elimination because if left untreated LTBI can progress to active TB disease. This additional burden can prevent achieving the global targets of TB elimination. Management of LTBI has been a low priority target for National TB Elimination Programs (NTEP) due to various challenges in the field settings. Areas covered: This article reviews the most recent advances in the field of LTBI management including newer diagnostics, treatments, vaccines, programmatic challenges, and gaps and suggests a way forward that can be adopted by NTEPs for LTBI. We searched the electronic databases of PubMed, Scopus, and Web of Science for studies published between 2010 to 2020 using MeSH terms: Latent TB Diagnosis, TB preventive therapy, Vaccines, LTBI, and HIV/ COVID. Expert opinion: NTEPs of developing countries should offer a better, point-of-care diagnostic, and effective treatment for LTBI to reduce the number of new TB cases arising from people infected with M.tb. Awareness about LTBI should be increased among the health system staff and the public. More funding is needed to advance research as well as implement the newer findings in the NTEP to achieve the End TB targets by 2035.

The objective of this study was to evaluate the determinants of weight gain during pregnancy. The study adopted a prospective cohort design with four follow-up waves and included a sample of 255 pregnant women that received prenatal care at a public health care facility in Rio de Janeiro, Brazil. A mixed-effects linear longitudinal regression model was used, having as the dependent variable the weight assessed in four follow-up waves, and as independent variables: demographic, socioeconomic, reproductive, behavioral, and nutritional data. Mean weight gain was 0.413kg per gestational week, consistent with recommendations by the Institute of Medicine. Per capita family income and smoking were associated with total weight gain during gestation. According to the longitudinal multiple linear regression model, age (beta = 0.6315), menarche (beta = -2.3861), triglycerides (beta = 0.0437), blood glucose (beta = 0.1544), and adequacy of energy consumption (beta = -0.0642) were associated with gestational weight gain. Special attention should be given to these sub-groups, due to increased risk of excessive weight gain.

In this study, the problem of finding the complete trajectory of prop- agation and the limiting load in plates with internal straight cracks is extended to the non-linear field. In particular, results concerning concrete plates in bi-axial ten- sile loading are shown. The concrete constitutive law adopted for this purpose is monotonic non-decreasing, as following according to previous studies of the author on monotonic mono-axial loading. The analysis is performed in a discrete form, by means of the Cell Method (CM). The aim of this study is both to test the new concrete constitutive law in biaxial tensile load and to verify the applicability of the CM in crack propagation problems for bodies of non-linear material. The discrete analysis allows us to identify the crack initiation without using the stress intensity factors.

Abstrak : Tujuan dari penelitian ini adalah untuk mengetahui tentang Peran Guru Sebagai Induk Dari Semua Profesi Dalam Bidang Pendidikan Formal. Metode yang digunakan dalam penelitian ini adalah metode kualitatif, karena data penelitiannya tidak berbentuk angka melainkan menggunakan Kuesioner Pertanyaan tentang suasana kerja, kualitas pelayanan seorang guru saat pembelajaran atau gaya kepemimpinan seorang guru sebagai sebuah profesi. Guru merupakan unsur yang sangat penting dan tidak bisa diabaikan begitu saja dalam proses belajar mengajar, sebab guru dapat menetukan berhasil atau tidaknya sebuah proses belajar mengajar. Oleh karena itu, dalam proses pendidikan dan pengajaran perlu tersedianya guru yang profesional, artinya ialah disamping menguasai materi pelajaran, metode mengajar, juga mengerti tentang dasardasar pendidikan. Dasar-dasar pendidikan amat sangat penting diketahui oleh seorang guru dalam melaksanakan tugasnya yang mulia sebagai pengajar atau pendidik, hal ini merupakan sebagai sarana untuk membangkitkan dan memotivasi siswa dalam proses belajar mereka. Walaupun penguasaan materinya sangat baik, akan tetapi tidak didukung oleh pengetahuan akan faktor-faktor didaktis, maka akan menimbulkan dampak sebuah hambatan dalam penguasaan materi bagi siswa terhadap apa-apa yang disampaikan oleh guru tersebut. Meskipun terhadap pengalaman belajar justru menjadikan guru lebih mudah dalam menyampaikan pelajaran disertai dengan penggunaan metode yang baik dan tepat.

This paper presents a mathematical modeling with parameters identification of Unmanned Aerial Vehicle (UAV) system or hexarotor system using the Hamiltonian approach. The mathematical model of the hexarotor is derived from the Hamiltonian approach which involved the storage, dissipation, and routing of energy elements from the UAV. This UAV model parameters identification method is proposed as an alternative to the commonly used wind tunnel testing, which is complex and tedious. This Hamiltonian model is made of a fully actuated subsystem with roll, pitch, and yaw angles as output, as well as an under-actuated subsystem with position coordinates as its output. Thrust constant, drag constant and speed of hexarotor are determined through the experimental setup while moment of inertia is determined by physical measurement and calculation. The outcome from this research works demonstrates an undemanding, yet effective method of modeling an UAV, and is useful for designing nonlinear controller to perform the important UAV tasks such as taking off, hovering, and landing.

Since the above was written in i9oi I have seen no reason to modify the opinion thiere' expressed; on the contrary, cumulative experience has more and more convinced me of its truth. The failure to obtain a shadow of the stone in the first of Mr. Clement Lucas's cases is not surprising. As far as my experience goes it is next to impossible to find the shadow of -a renal calculus in a stout patient. Even Mr. Lucas's second ease will not, I venture to think, appear strange to those with large experience in x-ray work. Such cases must have occurred to 'them all. Such a case at least has occurred to myself. A lady who was passing a considerable amount of pus was x-rayed for a stone in the kidney. The skiagraph showed nothing but an obscure mottling on the right side, but subsequently fragments of a phosphatic stone were passed. If we remember the density of the pus-shadow I think we need not be surprised if we fail to find a stone that 48 surrounded by pus in the pelvis of the kidney.-I am, etc., London, W., Oct. 2nd.

Abstract Objective The objective of this study was to evaluate an extended role for the physiotherapist in primary care in referring patients to plain X-ray. Methods This prospective cohort study was set in a single region in Sweden. It included 20 physiotherapists who were educated in a 1-day training in performing referral to X-ray, along with 107 patients with musculoskeletal disorders who were referred to X-ray. We evaluated referral quality and patient and physiotherapist satisfaction and calculated healthcare and patient costs. Results All referrals fulfilled the basic requirements of quality, and 78% were classified as good, fulfilling all criteria. Both patients and physiotherapists were satisfied with the extended role for the physiotherapist that decreased the waiting time to diagnosis and to adequate treatment. Costs were reduced for patients (by €53/patient) and healthcare (by €6286.2/107 patients). The cost to visit a physician was twice that of a physiotherapist visit. Conclusions An extended role for physiotherapists in primary care in referring patients to X-ray was effective and safe for patients and reduced costs for patients and for healthcare. Physiotherapists in primary care were able to refer patients to X-ray after a 1 day of training, and the extended role freed up 45 min of physician time for each patient with a musculoskeletal disorder in need of an X-ray.

The use of trade terms in sales contracts, especially international sales contracts, is customary and very common since it contributes to the acceleration of business transactions, concurrently increasing their certainty and predictability. The ICC Rules for the use of domestic and international trade terms -INCOTERMS 2020 have been in effective use since 1 January 2020. Their goal is to enable the development of global trade in an easier, more effective and safer manner. In this paper, the author analyses the development, importance and legal nature of INCOTERMS, with special reference to its current 2020 revision and particular focus on the seller's obligation to deliver the goods and risk transfer from the seller to the buyer.

In the present work we propose and analyze a fully coupled virtual element method of high order for solving the two dimensional nonstationary Boussinesq system in terms of the stream-function and temperature fields. The discretization for the spatial variables is based on the coupling C 1 - and C 0 -conforming virtual element approaches, while a backward Euler scheme is employed for the temporal variable. Well-posedness and unconditional stability of the fully-discrete problem is provided. Moreover, error estimates in H 2 - and H 1 -norms are derived for the stream-function and temperature, respectively. Finally, a set of benchmark tests are reported to confirm the theoretical error bounds and illustrate the behavior of the fully-discrete scheme.

A girl aged 4 years and 7 months was admitted to the Niigata University Hospital on Jan. 13, 1956. Her 2 sibs died of dyspepsia in early infancy and otherwise her family history was noncontributory. The delivery was uneventful, the body weighing 4125 g. at that time. The beginning of sitting up and walking was timely. Thereafter her physical and mental development was gradually retarded, and she could not speak even at the age of 4 years. In the meanwhile, lumbal kyphosis of the spine was noticed. She was diagnosed as rickets by a certain doctor, and in spite of gips application the deformity was not improved. On admission she was 87.5 cm. (normal : 96.7) in height and 14 kg. (normal : 16.5) in weight. The intelligence was not so high as that of a one-year-child (idocy). The skull was slightly box-like, measuring 48 cm. (normal: 48.6) in circumference. The face was grotesque ; the malar bones prominent, the eyes set apart, and the mouth opened with enlarged lips and tongue. Opacities of the cornea and hypertrichiosis of the head and trunk were also present. The neck was short. The breast had a funnel shape deformity but no rosary. The heart was enlarged to the left. The lungs showed nothing abnormal. The abdomen was protuberant with umbilical hernia. The liver and the spleen were palpable 3 and 1 finger breadths respectively below the costal margin. The extremities were short and thick and limited in their motilities to some extent. The clawhand was present bilaterally. The rontgenogram revealed a spatulalike appearance of the ribs and a beak-like deformity of the 1st. and 2nd. lumbal vertebrae. The sella turcica was elongated but flat. The tuberculin test and the serum Wassermann negative. The blood study disclosed 4.05 million red cells, 86% hemoglobin, and 6,600 white cells. Reilly’s granulations were absent in leukocytes. The urine examination showed nothing abnormal. The serum examination disclosed that total protein was 6.11 g./dl., calcium 9.5 mg./dl. and phosphorus 3.8 mg./dl. As a result of the liver function tests, T.T.T. was 6.7 M. u., C.C.F. (it), Gros (ti.), and cholin-esterase ApH 1.02. The splinal fluid was clear and colorless, containing 6 lymphocytes per cmm. ; the pressure was 500mm. water. Nonne (-). Pandy (-). C1 463, NaCl 763, and glucose 86 mg./dl. Her parents were cousins and had 7 children.

Advances in mobile and ubiquitous computing, wireless communications and mobile positioning have given a rise to a new class of mobile information systems and services, called location-based services (LBS) (Schiller & Voisard, 2004). Such services, like fleet management, cargo tracking, childcare, tourist services, transport management, traffic control and digital battlefield rely on the tracking of the continuously changing positions of entire populations of moving objects. LBSs are becoming ubiquitous. A traffic service may inform its users about traffic jams, traffic accidents and weather situations that are expected to be of relevance to the service user. A friend finder service may inform each user about the current whereabouts of friends. Other services may monitor and track the positions of emergency vehicles, police cars, security personnel, hazardous materials, or public transport. A more advanced location-based game service may allow a group of users to play and try to surround and catch “hostile” players. Monitoring and tracking moving objects require continuously registering the positions of mobile objects, and at any instance in time to know whether those objects are within the specified area, or a specified distance from known mobile/static objects, or which are its k nearest neighbors (kNN). To provide monitoring and tracking of moving objects in mobile application environments, it is highly desirable and sometimes critical for the service efficiency to provide accurate results to these requests and update them in real time, whenever moving objects enter or exit the regions of interest, or become the closest neighbors to the objects of interest. Monitoring and tracking LBS applications require database and application support to model and manage moving objects in both database and application domains. Such services must also provide efficient processing of continuous queries over moving objects. In contrast to regular queries that are evaluated only once, a continuous query remains active over a period of time. At any time there will be a number of continuous queries simultaneously running at the server. Each of these queries needs to be periodically re-evaluated as the objects and/or queries move. A major challenge for this problem is how to provide efficient processing of continuous queries with respect of CPU time, I/O time and network bandwidth utilization. The architecture of the monitoring and tracking LBS system is given in Figure 1.

In 1998, Jonathan Demme adapted for screen Toni Morrison’s critically acclaimed novel Beloved. This new cinematographic itinerary proves complex and problematic as the director chooses to reconfigure the heroine’s agonizing journey through memory and to freedom in times of slavery in a violent and non linear manner. His incursion into a haunted territory of African American history leads him to make radical choices such as selecting at once the fantastic genre and structuring his film around numerous flashbacks. The effect is gripping, but also stifling and disorientating for the spectator. His aesthetic approach, at times debatable, seems to redefine the moral implications of Sethe’s murder of her children and the inscription of distress and of the modes of survival on screen.

OBJECTIVE
Stroke is the second cause of mortality and the third cause of disability worldwide in adults. There is no published data about stroke in Agrı.We aim to define stroke subtypes and associated risk factors. Thus, we can be aware of stroke burden in rural areas and can develop strategies to reduce the stroke risk.
MATERIALS AND METHODS
Records of Agrı State Hospital were investigated for a period of 3 years retrospectively. Patients were divided to ischemic and hemorrhagic stroke groups. Hemorrhagic strokes were classified as subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH). Ischemic strokes were classified according to localization and etiology. Vascular risk factors for ischemic stroke were assessed and compared between groups. The differences between variables were evaluated using Pearson κi square test and one-way ANOVA.
RESULTS
There were 1246 patients evaluated for stroke in Emergency Department and 525 (42% of prediagnosis) patients were diagnosed as stroke. There were 25.3% hemorrhagic (5.1% SAH and 20.1% ICH) versus 74.6% ischemic stroke. Intensive care required for 61.6% of hemorrhagic and 22.4% of ischemic patients. The most prevalent localization was partial anterior circulation infarction, and the most known etiology was cardioembolism after unknown cause in ischemic strokes. The most encountered risk factor was hypertension (HT). Coronary artery disease history, HT, and atrial fibrillation (AF) were risk factors for recurrent stroke (P = .001).
CONCLUSION
Stroke types in Agrı resembles more to Asian population than Europe. Awareness for stroke, HT, and AF treatment could be the primary targets for stroke reduction in underdeveloped regions.

A regulatory scheme is suggested that identifies regions labeled "unacceptable" and "safe" as the upper and lower bounds and "operational" region is identified as the continuum between the two extremes. These regions are associated with levels of annual risk of cancer death for a given level of lifetime exposure between 100 mrem/yr and 1 mrem/yr, upper and lower bounds, respectively. Concern is expressed with establishing public health standards at ALARA (as low as reasonably achievable) levels, which result in lower standards for reference, and views are presented on several issues of interest in regulations for protection of the public from radioactivity in drinking water. Based on the regulatory scheme suggested, the author concludes that existing standards for drinking water appear to be lower than necessary.

Adaptive sampling can be used to reduce the number of produced events in networked control systems. Two types of adaptive sampling, namely time-variant periodic and deadband sampling are compared in this paper from the viewpoint of the control loop performance and the number of produced events. The comparison is fulfilled based on simulations.

Wireless sensor networks are uniquely characterized by tight energy and bandwidth constraints. These networks should be designed to provide enough data to their application so that a reliable description of the environment can be derived, while operating as energy-efficiently as possible and at the same time meeting bandwidth constraints. These goals are typically contradicting and must be balanced at the point where the application is best satisfied. In this paper, we address the problem of maximizing lifetime for a wireless sensor network while meeting a minimum level of reliability. This maximization is achieved by jointly scheduling active sensor sets and finding paths for data routing. Simulation results show that network lifetime can be significantly increased through such methods.

The transfer of health-related research knowledge between producers and users is a complex, dynamic and iterative process. There has been little research describing the preferred knowledge transfer strategies used by different stakeholder groups, including healthcare providers, policymakers and administrators. The purpose of the survey was to gain an understanding of the content and preferred dissemination strategies of knowledge users of briefing notes about the effectiveness of advanced practice nursing (APN) roles in Canada. An on-line cross-sectional survey was conducted from December 2011 to January 2012. Purposeful sampling was used to identify the target audience. The questionnaire included six items. The response rate was 44% (n=75/170). Participants identified that the briefing note should concisely summarize definitions for APN roles and information about the safety, effectiveness, cost savings and effective role implementation strategies. Multiple approaches were favoured to disseminate the information. Preferred dissemination strategies included personalized emails, meeting with briefing note recipients, engaging nurse practitioners and clinical nurse specialists in organizations where APN roles have been successfully implemented, engaging the media and using social media. The use of briefing notes has shown promise. More research is needed to evaluate the effectiveness of tailored briefing notes.

Round bamboo has aroused much interest in construction for its mechanical properties, but poor biological durability seriously restricts its application. In order to develop a suitable and effective preservative treatment method for round bamboo, copper naphthenate (CuN) was adopted and impregnated into round bamboo using heat-cold procedure. The distribution and retention of copper naphthenate in round bamboo were studied, and the biological durability represented by the mould and decay resistance were investigated. The results showed that the retention and fixation of copper reached 0.39 kg m−3 and 85.3%, respectively. Scanning electron microscopy–energy dispersive X-ray spectrometry further disclosed an increasing trend in the composition of CuN from the end inward. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy analyses later revealed that CuN could be fixed on bamboo in the form of hydrogen bond or complex reaction. Statistical analysis showed that the increasing concentration of CuN from 0.3% to 0.5% and 0.8% (calculated as Cu2+ content) has significant contribution against Trametes versicolor and Gloeophyllum trabeum in comparison with the untreated bamboo. Meanwhile, when the concentration of treating solution increased to 0.8 wt%, the resisting efficacy for Aspergillus niger, Penicillium citrinum and Trichoderma viride soared as high as 85.9%, 94.8% and 70.3%, respectively.

Un des principaux objectifs de la domestication est de selectionner des lignees a haut potentiel de croissance et a faible agressivite. L'etude des caracteristiques des animaux domestiques montre souvent de nombreux changements comportementaux dus aux conditions d'elevage, mais tres peu de donnees sont disponibles chez les poissons. Cet article decrit d'abord comment la mise en elevage affecte certains comportements, notamment alimentaires et natatoires, puis presente les modifications, au cours du developpement, des organes sensoriels et des aptitudes comportementales. Concernant le comportement alimentaire, les modifications sont principalement dues au fait que la distribution d'aliment ne correspond pas necessairement au rythme biologique des poissons et que la quantite d'aliment disponible est souvent bien superieure en elevage compare au milieu naturel. Le mode de distribution peut egalement influencer l'agressivite. Les conditions d'elevage (courant, densite animale ...) peuvent avoir des consequences sur l'agressivite des poissons, en modifiant leur repartition spatiale, avec en particulier une reduction de la distance interindividuelle. Le developpement des poissons en milieu d'elevage semble affecter certaines aptitudes comportementales en relation avec des modifications de leurs organes sensoriels (yeux, ligne laterale et odorat). Ces modifications sont generalement associees a une diminution de la vigilance avec notamment des consequences sur la capacite a echapper aux predateurs potentiels. Chez les poissons plats, le maintien en elevage modifie egalement l'adaptation chromatique. En conclusion, l'analyse des modifications comportementales induites par la domestication est un outil necessaire pour identifier les facteurs a prendre en compte afin d'identifier la mise en place du processus de domestication, de garantir le bien-etre des poissons et ainsi la durabilite du systeme d'elevage.

Diabetic retinopathy is considered one of the vision-threatening diseases among working-age population. The pathogenesis of the disease is regarded multifactorial and complex: capillary basement membrane thickening, loss of pericytes, microaneuryms, loss of endothelial cells, blood retinal barrier breakdown and other anatomic lesions might contribute to macular edema and/or neovascularization the two major and sight threatening complications of diabetic retinopathy. A number of proangiogenic, angiogenic and antiangiogenic factors are involved in the pathogenesis and progression of diabetic retinal disease, Vascular Endothelial Growth Factor (VEGF) being one of the most important. Other growth factors, which are known to participate in the pathogenesis of the disease, are: Platelet Derived Growth Factor (PDGF), Fibroblast Growth Factor (FGF), Hepatocyte Growth Factor (HGF), Transforming Growth Factor (TGF), Placental Endothelial Cell Growth Factor (PlGF), Connective Tissue Growth Factor (CTGF). Other molecules that are involved in the disease mechanisms are: intergrins, angiopoietins, protein kinase C (PKC), ephrins, interleukins, leptin, angiotensin, monocyte chemotactic protein (MCP), vascular cell adhesion molecule (VCAM), tissue plasminogen activator (TPA), and extracellular matrix metalloproteinases (ECM-MMPs). However, the intraocular concentration of angiogenic factors is counterbalanced by the ocular synthesis of several antioangiogenic factors such as pigment epithelial derived factor (PEDF), angiostatin, endostatin, thrombospondin, steroids, atrial natriuretic peptide (ANP), inteferon, aptamer, monoclonal antibodies, VEGF receptor blocker, VEGF gene suppressors, intracellular signal transduction inhibitors, and extracellular matrix antagonists. Growth stimulation or inhibition by these factors depends on the state of development and differentiation of the target tissue. The mechanisms of angiogenesis factor action are very different and most factors are multipotential; they stimulate proliferation or differentiation of endothelial cells. This review attempts to briefly outline the knowledge about peptide growth factor involvement in diabetic retinopathy. Further ongoing research may provide better understanding of molecular mechanisms, disease pathogenesis and therapeutic interactions.

A deterministic model for the transmission of an acute infectious disease in a heterogeneous, nonrandomly mixing population is developed. This model facilitates the estimation of transmission probabilities from the observed attack rates. If some of the members of the population are vaccinated, then the vaccine efficacy (VE), defined as the relative reduction in the transmission probability due to vaccination, can be estimated. We provide several estimators of VE, depending on the amount of information available on the mixing pattern and on the action of the vaccine. We show that if vaccinated persons increase the frequency of their contacts with infectious persons, then estimators ignoring this change in behavior may substantially underestimate the VE.

The religious formation of the Gaudya Vaisnava model viewed from the persuasion communication strategy is very interesting to study, because the activity will describe the elements of communication whether it is effective or not. From the point of view of the communicator, for example, is it capable of applying effective message delivery techniques? in terms of communicant, does it have the characteristics to be able to understand the meaning of the message as intended by the communicator? From the message element, is the message important to be known by the communicant ?. From the media element, is the media used to convey the message effective enough? And from the element of effect, whether the similarity in meaning of messages sent and received is able to change the communicant's attitude or behavior. Thus the process of religious formation will achieve its objectives if the elements of communication work effectively.There is no research on this matter, so it is not yet known whether the religious formation of the Gaudya Waisnava model has been effective or not. For this reason, this research was specifically carried out to describe and interpret (1) how does the religious development activities of the Gaudya Vaisnava model in Pasraman Sri-Sri Nitai Gaurangga? (2) how is the function of religious formation of the Gaudya Vaisnava model in Pasraman Sri-Sri Nitai Gaurangga?

Theoretical expressions for assessing the expected financial loss associated with the accuracy of the instrumentation and the associated probability in the presence of two and more gross errors have been developed in previous work. However, these expressions were given in a form of integrals without closed-form solutions. This article presents a generalized method to calculate the expected financial loss and the associated probability when two or more gross errors are present in a system. The application of financial loss calculation in the design and retrofit of a sensor network is illustrated in a simple example. © 2006 American Institute of Chemical Engineers AIChE J, 2006

A thalamic mode (or thalamocortical mode) refers to a particular arrangement of the response properties of the thalamocortical network that gives rise to a distinct input-output function. Since the thalamus controls the flow of information to the neocortex, a thalamic mode adjusts how thalamocortical cells relay sensory and corticothalamic information.

L'A. tente de determiner comment la forme textuelle d'un livre d'images fonctionne a la fois sur le plan lexical et visuel comme un systeme semiotique de signes et de codes pour creer du sens. Dans cette optique, il met plus particulierement l'accent sur deux aspects du livre d'images : 1) sa composition syntaxique, consideree comme un trait de l'integration des composants lexicaux et visuels dans le texte narratif intermediaire ; 2) les operations mentales (cognitives et affectives, conscientes et inconscientes) requises chez le lecteur par le texte, qui est considere comme un ensemble de signes et de codes lexicaux et visuels destine a faciliter la creation du sens et la reponse esthetique

This paper reports a new method of increasing surface flashover voltage on GIS epoxy spacer with incorporating nano/micro composites in SF6 gas. Simulation on the electric field grading effect on the surface flashover voltage for a GIS insulator model is carried out with nano/micro composites. To confirm the field grading effect, experiments are conducted to measure surface flashover voltage on a GIS spacer model. As the result, it is shown that nano/micro composites have the field grading effect due to their low relative permittivity.

There are three distinct regions with which a wedge shaped dental implant is in contact; the intraoral, transitional and intraosseous portions. The environment of each of these is different and will require special consideration. This investigation compares the epithelium found associated with a natural tooth to that which is found contiguous with the transitional region of an implant. The possibility of a pseudojunctional epithelium being formed in association with a glass collar processed onto the neck of a wedge shaped implant is examined. The histological appearance of a specimen in situ for 11 months shows an altered epithelial structure compared to that found adjacent to the neck of an unmodified titanium wedge shaped implant. Because the implant and glass must be mechanically separated from the tissue being examined, the value of demeneralized histological sections is limited. However, examination by a Scanning Electron Microscope of the surface of the glass after removal reveals an area of clear glass in the deeper region of the collar. Above this there is a deposit, the exact nature of which is unknown, but which migth be interpreted as the contents of the gingival crevice. Although this might be interpreted as a type of epithelial attachment, other factors are necessary to ensure close gingival adaptation and limitation on epithelial downgrowth.

Introducción: en los últimos años han incrementado los casos penales en los que la única prueba con la que se cuenta es la declaración de un menor. Ello ha motivado la búsqueda de factores que puedan afectar a la exactitud y credibilidad de su declaración. El presente estudio se centra en la influencia del conocimiento previo y de la repetición de entrevistas en la memoria y aceptación de la sugestión en una muestra de preescolares.Metodología: veintiséis preescolares participaron en tres sesiones. En la primera sesión, a la mitad de los participantes se les mostró qué es un cuelgabolsos (objeto desconocido), y a la otra mitad se les enseñó cómo se usa y, además, lo manipularon. En las sesiones 2 y 3, se realizaron dos entrevistas y en cada una de ellas se formularon preguntas cerradas sobre acciones reales y falsas, supuestamente llevadas a cabo en la sesión 1.Resultados: los resultados mostraron que el grupo con experiencia proporcionó en general más detalles sobre la acción que había experimentado con el cuelgabolsos en comparación con el grupo sin experiencia; sin embargo, esta diferencia se eliminó en la sesión 3, debido a la repetición de entrevistas. En cuanto a la acción falsa, se encontró efecto techo en la aceptación de la sugestión, y ambos grupos dieron una cantidad similar de detalles en las sesiones 2 y 3.Conclusiones: el conocimiento previo influye en la cantidad de detalles proporcionados únicamente si se pregunta una vez, si las preguntas son repetidas su efecto desaparece.

ABSTRACT Yoga practice is associated with improvements in eating disorder (ED) symptoms and body dissatisfaction. This study continued to evaluate this relationship while also assessing changes in variables negatively associated with ED symptoms (self-compassion, mindfulness, body appreciation, self-efficacy) that are emphasized throughout yoga. Men were also included in this study given studies have predominantly focused on women. Participants (N = 99, 77.8% women) were recruited from a university-implemented yoga course and completed assessments at the beginning (Time 1 (T1)) and end (Time 2 (T2)) of an eight-week yoga course meeting three times a week for fifty minutes. Body dissatisfaction (ps <.05) and ED pathology (p = .02) were lower at T2. Body appreciation (p < .001), self-compassion (p = .01), yoga self-efficacy (p = .004) were higher at T2. Some gender differences emerged. Men reported greater reductions in concern with being overweight, (Overweight Preoccupation) from T1 (M = 2.46, SD = 0.61) to T2 (M = 2.13, SD = 0.61) compared to women, T1 (M = 2.75, SD = 0.98) to T2 (M = 2.69, SD = 0.97) associated with yoga practice. Men also reported greater improvements in body satisfaction (Appearance Evaluation) from T1 (M = 3.60, SD = 0.49) to T2 (M = 3.90, SD = 0.34) compared with women, T1 (M = 3.48, SD = 0.58) to T2 (M = 3.39, SD = 0.52) associated with yoga practice. Results suggest yoga may be associated with concurrent changes in protective and risk factors for ED in a college population.

Power spectrum analysis of arterial blood pressure (BP) and heart rate (HR) has been used to investigate autonomic nervous system activity. Sympathetic-mediated vasomotor tone has been attributed to the BP power at frequencies between 0.05 and 0.15 Hz in humans and dogs and between 0.2 and 0.8 Hz in rats. In contrast, it has been suggested that the sympathetic nervous system is too sluggish to transmit frequencies higher than 0.017 Hz in dogs. Thus we investigated the frequency-response characteristics of the transmission of peripheral sympathetic nerve discharge to peripheral vascular resistance and arterial blood pressure in conscious rats. Eleven rats were instrumented with arterial catheters, nerve electrodes on the sympathetic splanchnic nerve, and flow probes on the superior mesenteric artery. The splanchnic nerve was cut proximal to the electrode to avoid afferent nerve stimulation. The next day the nerve was stimulated at frequencies of 0.05, 0.1, 0.2, 0.5, 1.0, and 2.0 Hz while mesenteric blood flow, BP, and HR were recorded in conscious rats. Mesenteric resistance (MR) was calculated off-line. Nerve stimulation at 0.05, 0.1, 0.2, 0.5, and 1.0 Hz significantly increased the power in MR at these respective frequencies. The greatest response was found between 0.2 and 0.5 Hz. These oscillations in MR were translated to oscillations in BP, but not in HR. Nerve stimulation on the second day, when the nerve was degenerated, did not elicit oscillations in MR or BP. We conclude that the peripheral sympathetic nervous system in rats can transmit signals at frequencies higher than those traditionally assigned to sympathetic vasomotor activity in several species, including humans, and may even overlap with the respiration-related high-frequency range.

Eutectic alloys of GaSb–FeGa1.3 were prepared by the vertical Bridgman method. A microstructure with the needle-shaped metallic FeGa1.3 phase oriented in a specific direction and uniformly distributed within the GaSb matrix was obtained. In GaSb–FeGa1.3 eutectics, the electrical and thermal conductivity, thermal diffusivity, thermoelectric power and Hall coefficients were investigated in a wide temperature range. These properties were measured at different mutual directions of current, thermal flow, magnetic field and metal phase inclusions. The influence of metallic inclusions on these properties was revealed and the distinctive characteristics of electron and phonon processes were established.

In the rendezvous of the concept of identity as cause of the human metamorphose and the category of ideology as a way to reproduce social domination, the present article discusses the labeling of the homeless people as vagabonds, dirty people, crazy persons, dangerous or poor. This feeling shared for many ends up to legitimate the physical violence against this people, as well as a bad reference in the constitution of their personal identities. Besides this perverse symbolic universe which they're submitted, are analyzed the madness- as escape from reality, the suicide - as the material consummation of the symbolic death, and the resistance against the social transformation- as an opponent to this labeling through the fight for their rights.

The psychological autopsy (PA) is a systematic method of assessing the psychological and contextual circumstances preceding suicide. The method requires interviews with one or more proxy respondents (i.e., informants) of suicide decedents. Procedural challenges that need to be addressed to conduct PA interviews are described in this article and recommendations for meeting these challenges in future PA investigations are made. Procedures addressed include determining the timing of PA interviews after suicide, designing the structure and flow of interviews, selection of proxy respondents, integrating interview data with information gathered from records, and selecting and training interviewers. This methodological article is the second in a two-part series-the first article focused on interview content.

Objective To compare the clinical outcome and postoperative complications of the treatment of supination-external rotation-type ankle fractures using the posterolateral approach in the prone position and the lateral approach in the supine position. Methods A retrospective cohort study was conducted in our hospital, including a total of 66 patients ranging from January 2013 to February 2016, regardless of age or sex. All the patients were classified as Lauge-Hansen supination-external rotation (SER)-type ankle fractures and were assigned to receive an open reduction and internal fixation (ORIF) through a posterolateral approach performed in the prone position (the “posterolateral approach group,” 32 patients), or a lateral approach performed in the supine position (the “Lateral Approach Group,” 34 patients). In the posterolateral approach group, 5 patients had Grade II fractures, 8 had Grade III fractures, and 19 had Grade IV fractures; among whom, 12 underwent fixation of the posterior malleolus with hollow screws and 6 with plates, and none of them had fixation of the distal tibiofibular syndesmosis; in the lateral approach group, 4 patients had Grade II fractures, 12 had Grade III fractures, and 18 had Grade IV fractures; among whom, 21 received fixation of the posterior malleolus, and 5 received fixation of the distal tibiofibular syndesmosis. The postoperative complications and ankle scores were recorded. Results After 1 year of follow-up, in the posterolateral approach group, the incision healed by primary intention and sutures were removed 2 weeks after the operation in all patients; 1 patient had pain in the region posterior to the fibula, presumably peroneal tendon irritation induced by internal fixation, which disappeared after fracture union and fixation device removal; no loosening or breakage of the internal fixation device was reported; the rate of good to excellent results was 96.8% at 12 months. In the lateral approach group: 1 case of wound infection, 1 case of necrosis of lateral skin flap, and 3 cases of lateral skin irritation were reported; the rate of good to excellent results was 94.6% at 12 months. Conclusion Compared with the traditional lateral approach, the posterolateral approach for the reduction and internal fixation of supination-external rotation-type ankle fractures performed in the prone position has more satisfactory clinical outcomes, with better reduction, more secure fixation, and smaller wound.

ABSTRACT First coming to prominence as the bassist of one of the earliest Spanish punk bands, Kaka de Luxe, Alaska became the public face of the Movida through a starring role in Pedro Almodóvar’s debut feature, Pepi, Luci, Bom y otras chicas del montón (1980), and a string of major hits as lead singer of Alaska y los Pegamoides and, subsequently, Alaska y Dinarama. The latter dissolved in 1989 when she and Nacho Canut, a constant presence and songwriter in all of her groups, formed Fangoria, a formation she has fronted to the current day. Especially following the success of MTV reality show, Alaska y Mario (2011–), the star has been heavily criticized for associating with reactionary figures, while simultaneously being variously celebrated and denigrated as a privileged icon of the Culture of the Transition. The commonplace of the two Spains as applied to the Movida has less to do with the political left and right than with a division between those who see politics everywhere, and those whom refuse to see them anywhere. This article will suggest that, while Alaska’s (a)political stance is not unproblematic, commentators who reduce everything to ideology have been ill-equipped to critique the achievements and limitations of a cultural phenomenon that sought to reify aesthetics at the expense of all other considerations, politics included.

This paper presents and discusses the experimental study on the mechanical properties of LBL column both under axial and eccentric compression. The results shows that the ultimate load for the eccentric compression specimens with the eccentricity values of 30 mm and 110 mm are 95.2 kN and 31.8 kN respectively. Eccentricity is one of the main influencing factors for the ultimate bearing capacity of the LBL columns. Because of the vulnerability of the mechanical connections or natural nodes to tensile stress and secondly, laminated bamboo is vulnerable to defects that has more detrimental influence on the tensile resistance of the material. The variation in strain for the laminated bamboo lumber column sections is linear throughout the loading process, following standard normal section bending theory which is similar as that for the beam.

ABSTRACT Slit cleavage into N-terminal and C-terminal polypeptides is essential for restricting the range of Slit activity. Although the Slit cleavage site has been characterized previously and is evolutionally conserved, the identity of the protease that cleaves Slit remains elusive. Our previous analysis indicated that Slit cleavage is essential to immobilize the active Slit-N at the tendon cell surfaces, mediating the arrest of muscle elongation. In an attempt to identify the protease required for Slit cleavage we performed an RNAi-based assay in the ectoderm and followed the process of elongation of the lateral transverse muscles toward tendon cells. The screen led to the identification of the Drosophila homolog of pheromone convertase 2 (PC2), Amontillado (Amon), as an essential protease for Slit cleavage. Further analysis indicated that Slit mobility on SDS polyacrylamide gel electrophoresis (SDS-PAGE) is slightly up-shifted in amon mutants, and its conventional cleavage into the Slit-N and Slit-C polypeptides is attenuated. Consistent with the requirement for amon to promote Slit cleavage and membrane immobilization of Slit-N, the muscle phenotype of amon mutant embryos was rescued by co-expressing a membrane-bound form of full-length Slit lacking the cleavage site and knocked into the slit locus. The identification of a novel protease component essential for Slit processing may represent an additional regulatory step in the Slit signaling pathway. Summary: The Drosophila homolog of pheromone convertase 2 (PC2), amontillado (Amon), is shown to contribute to Slit processing and further cleavage into an N-Slit, essential for Slit activity in directing muscle patterning.

OCCUPATIONAL APPLICATIONS This study showed an overall positive judgment of users when using a passive lower-limb exoskeleton (Chairless Chair®, noonee AG, Switzerland), in terms of high levels of comfort and low levels of discomfort. These findings are promising with regard to field implementation, although final steps in the exoskeleton design first have to be taken. In future feasibility studies, users’ acceptance of the exoskeleton should be investigated in the field. One important question that remains is when and for how long users should wear and use the exoskeleton, and areas of beneficial field application need to be defined with regard to primary, secondary, and tertiary prevention, which may provide guidelines for effective use. TECHNICAL ABSTRACT Background: Besides efficacy with regard to workload, subjective evaluation (wearing comfort and discomfort, and user acceptance) is an important secondary outcome to determine in field effectiveness studies, before true field implementation of industrial passive and active exoskeletons can be realized. Purpose: The aim of this study was to determine how discomfort and wearer comfort change with the use of a passive lower-limb exoskeleton and how both are influenced by optimal and suboptimal working heights. Methods: Forty-five male participants were included in the study. Each performed a simulated assembly task in seven experimental conditions, which were a combination of working posture (standing without the exoskeleton, and high and low sitting on the exoskeleton) and working height (optimal and suboptimal). The simulated task included screwing, clip fitting, and cable mounting, and was performed for 21 min in each condition. Before and after each condition, participants rated their level of discomfort, and after completed all conditions they provided feedback about comfort. Results: Initial discomfort ratings (i.e., before each condition) were all < 2 (on a 0–10 scale), with a mean initial rating of 0.03 (SD 0.22). Overall increases in discomfort levels across conditions remained below 1.4, but were significantly lower in the standing working posture without the exoskeleton. Wearer comfort was rated high, with a general mean rating of 7.9 (on a 1–10 scale). Wearer comfort was rated slightly higher for the low versus the high sitting configuration on the exoskeleton. Conclusions: These subjective assessments of discomfort and wearer comfort suggest that the Chairless Chair® has the potential to be used in the occupational context. Future work is recommended, though, include field testing to evaluate user acceptability of the exoskeleton as well as a thorough evaluation of work situations wherein workers can benefit from the use of the exoskeleton.

The aim of the work is developing and investigating an electric circuit of a deterministic chaos ring oscillator having a delay element in a feedback loop and based on a MOS transistor structure with negative differential resistance. New circuits of active elements based on MOS transistor structures with electrically controlled parameters of static λ-type I-V curves for deterministic chaos ring oscillators have been proposed. Experimental facilities have been developed and results have been obtained after investigating static and dynamic I-V curves for the MOS transistor structures with negative resistance. Results of simulating the deterministic chaos ring oscillator based on the MOS transistor structure with negative differential resistance in PSPICE software have been obtained.

HighlightsLab-scale beef manure bedded packs were constructed to evaluate the temperature effect on gaseous emissions.Temperature had a tendency to increase ammonia, hydrogen sulfide, and greenhouse gases in the headspace above bedded packs over time.Abstract. Throughout the Upper Midwest, producers have observed increased land and fertilizer prices, resulting in increased popularity of confinement feeding facilities such as mono-slope and hoop barns with bedded packs. Environmental and public pressure has been placed on the agriculture community to reduce ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gas (GHG) emissions from concentrated animal feeding operations (CAFOs). This study was conducted to determine the effects of bedding material (corn stover (CS), bean stover (BS), wheat straw (WS), or pine wood chips (PC)) and ambient temperature (15°C (COOL) or 30°C (HOT)) on NH3, CH4, CO2, N2O, and H2S flux in air samples collected in the headspace above lab-scale bedded packs. All bedded packs were housed at 18°C for an initial three weeks before being placed in their respective environmental chambers at 15°C or 30°C for the remainder of the 6-week study period. Significant two-way interactions of bedding material by temperature for NH3 flux were observed (p = 0.0094). Ammonia flux was greater at higher temperature, while CS bedding had the lowest NH3 emissions compared to the other bedding materials. A significant two-way interaction of bedding material by temperature for H2S flux was observed (p < 0.0001), with significantly greater H2S produced in the headspace of COOL-BS packs compared to all other treatments. Additionally, a significant (p = 0.0357) two-way interaction of temperature by age of the bedded pack was observed for H2S flux. Hydrogen sulfide flux appeared to be influenced by low bedded pack pH to a greater extent than by increase in temperature. Greenhouse gas emissions tended to be higher from bedded packs in HOT treatments. A significant (p = 0.0422) interaction among bedding material, temperature, and age of the bedded pack was observed for CH4. Significantly greater CH4 flux was observed in the headspace above HOT-BS and HOT-CS at week 6 compared to all other treatments. A significant two-way interaction of bedding material by temperature was observed for CO2 flux (p = 0.0189). The largest CO2 levels were observed above WS bedding material regardless of temperature. Nitrous oxide flux decreased over the 6-week study for all bedded packs, while WS and PC bedded packs produced the greatest N2O flux. The results indicate that feedlot operators maintaining bedded pack facilities will have the greatest reduction in NH3 emissions when using CS bedding, regardless of ambient temperature. To reduce CH4 emissions, producers should avoid allowing BS and CS bedded packs that are maintained for longer than six weeks in HOT (30°C) temperatures; frequent cleaning during summer months is recommended. Based on the CO2 equivalents of CH4 and N2O, producers should consider PC as an option to reduce GHG emissions.

To increase the output of Laminaria in Japan, considerable importance has been attached to the propagation of Laminaria that grow on natural reefs. Various methods of propagation have been used, namely, planting of stones and blasting of reefs. In spite of these efforts, the productivity of Laminaria of good quality has fluctuated remarkably, and further, it has been decreasing gradually. A method of cultivation was then tried. At first, however, production of Laminaria of good quality did not increase readily, because this plant usually requires two winters to attain its commercial size.As a result, the improvement of techniques for cultivating Laminaria has become an important subject for research workers. During the study of the cultivative process, we have succeeded in developing techniques for rearing 2-yr-old plants in 1 yr without debasing their quality. This method is called the "Forced Cultivation Technique."Since 1969 the yield of cultivated plants using this technique has increased remarkably i...

Indexing/retrieving sets of iris biometric signatures has been a topic of increasing popularity, mostly due to the deployment of iris recognition systems in nationwide scale scenarios. In these conditions, for each identification attempt, there might exist hundreds of millions of enrolled identities and is unrealistic to match the probe against all gallery elements in a reasonable amount of time. Hence, the idea of indexing/retrieval is - upon receiving one sample - to find in a quick way a subset of elements in the database that most probably contains the identity of interest, i.e., the one corresponding to the probe. Most of the state-of-the-art strategies to index iris biometric signatures were devised to decision environments with a clear separation between genuine and impostor matching scores. However, if iris recognition systems work in low quality data, the resulting decision environments are poorly separable, with a significant overlap between the distributions of both matching scores. This chapter summarizes the state-of-the-art in terms of iris biometric indexing/retrieval and focuses in an indexing/retrieval method for such low quality data and operates at the code level, i.e., after the signature encoding process. Gallery codes are decomposed at multiple scales, and using the most reliable components of each scale, their position in a n-ary tree is determined. During retrieval, the probe is decomposed similarly, and the distances to multi-scale centroids are used to penalize paths in the tree. At the end, only a subset of branches is traversed up to the last level.

The cuttlefish, Sepia officinalis, provides a fascinating opportunity to investigate the mechanisms of camouflage as it rapidly changes its body patterns in response to the visual environment. We investigated how edge information determines camouflage responses through the use of spatially high-pass filtered ‘objects’ and of isolated edges. We then investigated how the body pattern responds to objects defined by texture (second-order information) compared with those defined by luminance. We found that (i) edge information alone is sufficient to elicit the body pattern known as Disruptive, which is the camouflage response given when a whole object is present, and furthermore, isolated edges cause the same response; and (ii) cuttlefish can distinguish and respond to objects of the same mean luminance as the background. These observations emphasize the importance of discrete objects (bounded by edges) in the cuttlefish's choice of camouflage, and more generally imply that figure–ground segregation by cuttlefish is similar to that in vertebrates, as might be predicted by their need to produce effective camouflage against vertebrate predators.

Atmospheric turbulence imposes the resolution limit attainable by large ground-based telescopes. This limit is lambda/r(0), where r(0) is the Fried parameter or seeing cell size. Working in the visible, adaptive optics systems can partially compensate for turbulence-induced distortions. By analogy with the Fried parameter, r(0), we have introduced a generalized Fried parameter, rho(0), that plays the same role as r(0) but in partial compensation. Using this parameter and the residual phase variance, we have described the phase structure function, estimated the point-spread function halo size, and derived an expression for the Strehl ratio as a function of the degree of compensation. Finally, it is shown that rho(0) represents the diameter of the coherent cells in the pupil domain.
