This work presents a novel ultra-wideband (UWB) bandpass filter (BPF) based on a conductor-backed coplanar waveguide structure with tunable transmission zeros. The symmetrical UWB BPF, which consists of the broadside-coupled transitions and the stub resonators in double-layer configuration, achieves a UWB bandwidth with transmission zeros. For characterizing this structure, the equivalent-circuit model is established to realize a four-pole response with two transmission zeros located close to the passband edges. To eliminate the interference of the coexisting wireless local area network (WLAN) within the UWB spectrum, two slotlines are symmetrically arranged on the ground plane of UWB BPF to generate the band-notched frequencies at 5.2 and 5.8 GHz simultaneously. The proposed UWB BPFs have the advantages of compact size, low insertion loss, good selectivity, and flat group delay. All results obtained from the equivalent-circuit model and the full-wave simulation are verified by measurements.

The bond fluctuation method is used to simulate both nonconcatenated entangled and interpenetrating melts of ring polymers. We find that the swelling of interpenetrating rings upon dilution follows the same laws as for linear chains. Knotting and linking probabilities of ring polymers in semidilute solution are analyzed using the HOMFLY polynomial. We find an exponential decay of the knotting probability of rings. The correlation length of the semidilute solution can be used to superimpose knotting data at different concentrations. A power law dependence fn ∼ ϕR2 ∼ ϕ0.77N for the average number fn of linked rings per ring at concentrations larger than the overlap volume fraction of rings ϕ* is determined from the simulation data. The fraction of nonconcatenated rings displays an exponential decay POO ∼ exp(−fn), which indicates fn to provide the entropic effort for not forming concatenated conformations. On the basis of these results, we find four different regimes for the conformations of rings in melts ...

Carbon fiber-reinforced polymers are considered a promising composite for many industrial applications including in the automation, renewable energy, and aerospace industries. They exhibit exceptional properties such as a high strength-to-weight ratio and high wear resistance and stiffness, which give them an advantage over other conventional materials such as metals. Various polymers can be used as matrices such as thermosetting, thermoplastic, and elastomers polymers. This comprehensive review focuses on carbon fiber-reinforced thermoplastic polymers due to the advantages of thermoplastic compared to thermosetting and elastomer polymers. These advantages include recyclability, ease of processability, flexibility, and shorter production time. The related properties such as strength, modulus, thermal conductivity, and stability, as well as electrical conductivity, are discussed in depth. Additionally, the modification techniques of the surface of carbon fiber, including the chemical and physical methods, are thoroughly explored. Overall, this review represents and summarizes the future prospective and research developments carried out on carbon fiber-reinforced thermoplastic polymers.

Garantizar la atención prenatal adecuada es responsabilidad de los gobiernos de turno, es decir que el desarrollo de la salud materna es el resultado de la aplicación de políticas e inversión pública, del funcionamiento de los servicios obstétricos en forma estandarizada y con alta calidad para los pacientes de bajo y alto riesgo tanto en hospitales y centros de salud, sin embargo el insuficiente número de profesionales especialistas, las colas para las atenciones, la falta de ecógrafos de alta gama que ayuden al diagnóstico, la falta de medicinas y reactivos en los laboratorios son factores que no contribuyen a un control prenatal (CPN) de calidad de un gran sector de la población.
En la revista “Sociedad justa, vidas saludables”, se enfatiza la importancia de garantizar servicios de maternidad de alta calidad en todo el gradiente social (1).
En nuestro país, según la Encuesta Demográfica y de Salud (ENDES) del 2017 indica que la cobertura de la atención prenatal no ha sido suficiente y advierte que se debe de educarse para que este se realice tempranamente (2), un buen CPN se ha asociado a un menor riesgo de parto pretérmino, bajo peso al nacer y la disminución de la permanencia prolongada en unidades de cuidados neonatales, importante decir que numerosas atenciones prenatales no es garantía de un buen cuidado de la gestación (3).

of applying idealizations like Chomsky's homogeneity assumption to practical tasks like language teaching, where variability is the rule and the problem (335). Chapter nine is a very general survey of semantics and includes an outline of a theory of speech acts, and chapter ten deals mainly with formal syntax, featuring a rather thorough discussion of Harris's and Chomsky's concept of transformation and the latter's notion of deep structure. The eleventh and final chapter is an investigation, typically very formal, of the problem of language families, dialects, and grammars thereof, emphasizing their abstract nature. The chapter and the book end, characteristically, with a section on "closing questions" (346-7), dealing mostly with language contact, change, and planning, that he considers still unanswered and worth following up. They make a fitting conclusion to a book that is highly eclectic and objective and in which the author's concern with theory and metatheory is balanced by his humanistic and practical concerns. But it should be repeated that the book is neither a general introduction nor a good synthesis. It is a difficult and demanding book that should appeal to linguists concerned with the logical status of linguistic theories. It should also be of interest to English-speaking readers as the personal, critical statement of a European linguist who is aware both of the great achievements of American linguistics and of its limitations and who is actively engaged in expanding the model beyond the sentence and in the direction of discourse, semantics, and the use of language in real situations.

The mountain pine beetle, Dendroctonus ponderosae, and its fungal associates are devastating the lodgepole pine forests in British Columbia, Canada. During our fungal survey, an unknown Leptographium species has been consistently isolated from both D. ponderosae and infested lodgepole pine (Pinus contorta var. latifolia). This Leptographium species has similar morphology with the Leptographium anamorph of Ophiostoma clavigerum whose association with the D. ponderosae is well known. However, thorough morphological comparisons showed that this fungus is distinct from all the other Leptographium species described in the literature, and especially from O. clavigerum. Comparison of DNA sequences of multiple loci and the profiles by the PCR-RFLP marker also confirmed that this Leptographium species represents an undescribed taxon. Based on its distinct morphological, physiological characteristics and phylogenetic position, we describe it as L. longiclavatum sp. nov.

Purpose - – This paper aims to take note of the need to better understand cost consciousness from a management accounting perspective and serves as an exploratory study striving to analyze how the notion has been addressed by management accounting scholars. Design/methodology/approach - – This paper presents the findings of a thorough literature review identifying the drivers, interpretations, definitions and results which management accounting scholars have associated with cost consciousness. Findings - – This paper has synthesized the definitions and interpretations by considering their conceptual broadness and the subjects that cost consciousness characterizes. In addition, various potential drivers of cost consciousness have been identified where management control systems play a major role. Also, this paper summarizes both the positive and negative outcomes which scholars seem to expect from an increase of cost consciousness. Research limitations/implications - – Given that no prior work has focused on the conceptual development of cost consciousness, it was necessary to infer most of the interpretations, drivers and results which management accounting scholars have associated to the cost consciousness notion. Originality/value - – Cost consciousness is a concept that appears in hundreds of peer-reviewed articles on management accounting. However, only a handful of management accounting scholars have defined or evaluated this concept to a certain degree. As a result, what management accountants believe cost consciousness to be, how it is driven and what result may be expected from it, is nowhere to be found in any synthesized manner. The findings of this paper develop the concept of cost consciousness by illuminating the common use of the construct across various disciplines.

A 53 year old male with known metastatic non-small cell lung cancer was admitted with a one-week history of increasing shortness of breath. During the four months prior to his admission he had been treated with cisplatin-based chemotherapy, and had undergone left sided thoracenteses at 3-4 week intervals, the most recent, 4 weeks prior to admission. On admission, the patient was dyspnoeic, his pulse rate was 110/min, respiratory rate 28/min, and blood pressure 130/80 mmHg . He had moderate jugular venous distension and diminished breath sounds in the lower half of his left lung. Heart sounds were relatively loud and no murmurs were evident. The abdomen was soft and the liver moderately enlarged. There was mild oedema of both lower extremities. ECG revealed a sinus tachycardia with normal voltage. The chest X-ray prior to the last thoracentesis is shown in figure 1, and that from the current admission in figure 2. Figure 1 Shortness Of Breath In A Lung Cancer Patient

Anyang pool is the leisure facility which was constructed in the Japanese colonial era and widely used even after independence. That is why it is sufficiently necessary to study its aspect after independence in terms of historical investigation. The purpose of this thesis is to describe how Anyang pool has been used after independence most clearly. Study method of this thesis is the method of literature review using the photos of newspaper, official gazette and magazine. And this thesis is meaningful in that it examines the leisure facility that existed in the metropolitan area not in the province, and expands the width of consideration for leisure facility at the early days of foundation of Korea. In this regard, this thesis concludes that Anyang pool had played not less role after liberation than in Japanese colonial era.

RESUME Au cours du dernier demi-siecle, les aides publiques a l'art et a la culture ont ete inscrites aux chapitres de la responsabilite publique. Si le mecenat public a une longue tradition derriere lui, sa formulation actuelle en politiques culturelles est relativement recente, etant apparue surtout dans l'apres-guerre. L'ideologie du capitalisme et les valeurs protestantes sont des facteurs qui ont empeche, a une certaine epoque, les gouvernements occidentaux d'adopter des politiques culturelles explicites. Avec le declin des valeurs morales et l'avenement de la «Welfare State», les gouvernements en sont venus a reconnaitre la legitimite des besoins artistiques et culturels et a se reconnaitre, la, une responsabilite. L'institutionnalisation du mecenat public s'est manifestee par la mise en place de structures permanentes chargees de l'adoption ou de l'application des politiques culturelles, l'adoption de lois et reglements et par l'affectation de budgets specifiques au developpement culturel. La crise...

PURPOSE OF REVIEW
Combined hormonal contraception has been contraindicated in migraines, especially in migraines with aura, because of ischemic stroke risk. Newer formulations are now available and physicians may unnecessarily be limiting access to contraceptive and medical therapeutic options for patients with migraines. This review summarizes the available data regarding ischemic stroke risk of modern combined hormonal contraception in the setting of migraines.
RECENT FINDINGS
Limited data exists on current formulations of combined hormonal contraception and outcomes in migraine patients. Studies indicate ischemic stroke risk may be estrogen dose related with high dose formulations having the highest risk. Absolute risk of ischemic stroke with combined hormonal contraception and migraines is low.
SUMMARY
Ischemic stroke risk in combined hormonal contraception users in the setting of migraines is low and an individual approach may be more appropriate than current guidelines.

A method is described for the determination of ketone bodies in blood, based on (1) their conversion to acetone by boiling in Greenberg and Lester's microrefluxing units, (2) the reaction of acetone with alkaline salicylaldehyde by a modification of Thin and Robertson's microdiffusion technic, and (3) the colorimetric determination of salicylacetone in water.
A study of the effects of varying concentrations of dichromate and sulfuric acid on the recoveries of acetoacetic and β-hydroxybutyric acids is presented and the optimum reagent concentrations are established. Recoveries of 100 per cent are obtained for both acetoacetic and β-hydroxybutyric acids. The method is particularly sensitive to small changes of ketone bodies. In the range 0-8 mg. acetone per 100 ml. blood, differences of 0.06 mg./100 ml. are detected with ease.

Two measures of dependence for multivariate t and Cauchy random variables are developed based on Kullback–Leibler number. The mutual information number T(X) is obtained in a closed expression form, as well as its asymptotic distribution. A dependence coefficient ρ1, is defined (based on the Kullback–Leibler number) with the properties of ρ1=0 indicating independence and ρ1=1indicating degeneracy. Two real life examples from the stock market are used to analyze the level of dependence and correlation among stocks.

For clarification of the surface active effect of P 2 O 5 in the reaction kinetics and mechanism of the various metallurgical processes, the effect of P 2 O 5 addition on the reaction rate of CO 2 dissociation on the surface of the Fe t O, Fe t O-CaO (mol%Fe t O : mol%CaO=6 : 4), Fe t O-SiO 2 (mol%Fe t O : mol%SiO 2 =7 : 3), and Fe t O-CaO-SiO 2 (mol%Fe t O=35, mol%CaO/mol%SiO 2 =1.13-1.27 and 1.36-1.47) melts was investigated at 1 773 K with P C O 2 /P C O =1 by using isotope exchange technique. The rate constant decreased with increasing P 2 O 5 content of melts and the residual rate constant was observed at high P 2 O 5 content. However, the change of the Fe 3 + /Fe 2 + ratio of molten oxide was not observed. Results were analyzed by using "site blockage model" of P 2 O 5 , and it was concluded that the rate controlling step of CO 2 dissociation was the dissociation reaction of adsorbed CO 2 molecule on the surface of molten oxides.

Sheep, particularly lambs, with high circulating levels of Clostridium perfringens type D epsilon toxin develop severe neurologic signs and often die suddenly. On microscopic examination, in the brain, there is microvascular endothelial injury and diffuse vasogenic edema. The aquaporin (AQP) family of membrane water-channel proteins, especially AQP-4, is important in the regulation of water balance in the brain and facilitates reabsorption of excess fluid. In rats given epsilon toxin, generalized cerebral edema was demonstrated by marked albumin extravasation and was correlated with widespread upregulation of AQP-4 in astrocytes. These results suggest that AQP-4 has a role in the clearance of edema fluid from brains damaged by this clostridial toxin.

OBJECTIVES
The aim of this study was to explore the knowledge and attitude of Sultan Qaboos University students towards premarital screening program.
METHODS
A cross-sectional study conducted at the students' clinic from January to April 2011. A self-administered questionnaire was distributed to 590 unmarried Omani students of both genders. The questionnaire consisted of 3 main parts; the first part was based on socio-demographic data, the second part dealt with the students' knowledge about the premarital screening program while the third part explored their attitudes towards the screening program.
RESULTS
Most of the participants (n=469; 79%) were aware about the availability of premarital screening program in Oman. The main sources of information were: school/college (n=212; 36%), media (n=209; 35%), family and friends (n=197; 33%), and/or health services (n=181, 31%). The vast majority of the participants (n=540; 92%) thought it is important to carry out premarital screening and agreed to do it. Around half of the participants (n=313; 53%) favored having premarital screening as an obligatory procedure before marriage and about one third (n=212; 36%) favored making laws and regulation to prevent marriage in case of positive results.
CONCLUSION
Even though the majority of the participants thought it is important to carry out premarital screening; only half favored making it obligatory before marriage and one third favored making laws and regulations to prevent marriage in case of positive results. This reflects the importance of health education as a keystone in improving knowledge and attitude towards premarital screening program.

INTRODUCTION Sexual minority individuals experience elevated risk for smoking and violence due to a combination of general and unique identity-based risk factors. This study examined associations among sexual minority status, school-based violence, and tobacco use, among youth. METHODS Data for this secondary data analysis consisted of Chicago-specific data from the 2019 Youth Risk Behavior Surveillance System (n=1562). Current use (≥1 day during the previous 30 days) of any tobacco product (cigarettes, e-cigarettes, smokeless tobacco, and cigars) and school-based violence (avoided school because they felt unsafe, were threatened/injured with a weapon, were in a physical fight, and were bullied) were estimated by sexual orientation (heterosexual vs gay, lesbian, bisexual, and unsure). A chi-squared test was used to investigate associations among the variables. Path analysis was employed to examine possible mediation effects of school-based violence. RESULTS Thirty percent of sexual minority youth and 11.5% of heterosexual youth reported current tobacco use (χ2=55.91; p<0.001). Nearly one-third (31.8%) of youth reported school-based violence, with a higher rate (41.2%) reported by sexual minority youth compared to heterosexual youth (28.1%; χ2=19.48; p<0.001). Path analysis confirmed these associations, controlling for sex, age, and race/ethnicity. The model showed that sexual minority status increased odds of current tobacco use by a factor of 1.8 (95% CI: 1.3–2.6) via its relationship with school-based violence, explaining 33.8% of the total association between sexual minority status and tobacco use. CONCLUSIONS Tobacco use was higher among sexual minority youth. School-based violence partially mediated the association between sexual minority status and tobacco use. Findings highlight the need for tobacco prevention and treatment efforts for sexual minority youth and school-based interventions to reduce exposure to violence.

Digital image correlation is a non-contact optical method for measuring the displacement and strain on the surface of a material. The existing reliability-guided digital image correlation (RG-DIC) method is stable and reliable for a single image but it still needs a large calculational
resource for a sequence of images. Due to the decorrelation effect, the reference image must be replaced several times to correct the measurement results for an image sequence involving a large deformation or a discontinuous deformation. Since the process must be executed sequentially, image
by image, the total time required is often unacceptably large when the image sequence is long. The challenge is to find a way of improving the speed while retaining calculational reliability and measurement accuracy, which are important for the practical application of DIC. To address this
problem, an improved method is proposed in this paper. The parallel bottleneck caused by the decorrelation effect is solved through improving the parallelism to increase the processing speed. This approach can be used to calculate the strain field of the surface of the material in cases of
discontinuous deformation, such as in the area near to a crack. Compared with existing methods, this method not only retains the calculational reliability but also greatly improves calculation speed, especially on current multi-core computing platforms.

A review is given of the development of boiler-plant instrumentation, from the early use of measuring instruments as mere safety devices to the modern employment of remote centralized control, based upon the comprehensive measurement of the operating conditions. It is contended that, as improvements in plant design and operating efficiency are governed by the degree to which their dependent factors are known and understood, exploratory measurement must embrace all the quantities which are measurable, while the operating measurements must include those of all the variables which are susceptible to regulation. A table of essential measuring instruments for shell-type and water-tube type boilers is included. Remote manual control is then compared with automatic control. The purpose is to show that, as measurement is now the acknowledged basis for control, it follows that the measuring instruments which detect and report the adverse tendencies should be used to institute the corrections needed to arrest them, wherever this is practicable.

We present a solution to the electroencephalographs (EEG) forward problem of computing the scalp electric potentials for the case when the head's geometry is modeled using a four-shell ellipsoidal geometry and the brain sources with an equivalent current dipole (ECD). The proposed solution includes terms up to the fourth-order ellipsoidal harmonics and we compare this new approximation against those that only considered up to second- and third-order harmonics. Our comparisons use as reference a solution in which a tessellated volume approximates the head and the forward problem is solved through the boundary element method (BEM). We also assess the solution to the inverse problem of estimating the magnitude of an ECD through different harmonic approximations. Our results show that the fourth-order solution provides a better estimate of the ECD in comparison to lesser order ones.

Remittent idiopathic necrotizing acrocyanosis is a very rare condition characterized by persistent systemic cyanotic or erythrocyanotic discoloration of hands and feet. It is associated with pain, tenderness of fingers and toes and may present as ulceration or gangrene of extremities. It is aggravated with cold exposure but persists even in summer. Acrocyanosis is not due to any systemic disease; peripheral arteriolar constriction with secondary vasodilatation due to disordered vascular tone of unknown etiology has been postulated. It responds to peripheral vasodilator drug but usually needs continuous long term therapy along with avoidance of cold exposure. We report the case of a 53-year-old male farmer with remittent necrotizing acrocyanosis.

Abstract Group coextensions of monoids, which generalise Schreier-type extensions of groups, have originally been defined by P.A. Grillet and J. Leech. The present paper deals with pomonoids, that is, monoids that are endowed with a compatible partial order. Following the lines of the unordered case, we define pogroup coextensions of pomonoids. We furthermore generalise the construction to the case that pomonoids instead of pogroups are used as the extending structures. The intended application lies in fuzzy logic, where triangular norms are those binary operations that are commonly used to interpret the conjunction. We present conditions under which the coextension of a finite totally ordered monoid leads to a triangular norm. Triangular norms of a certain type can therefore be classified on the basis of the presented results.

Precise and accordant detection and prognosis, CAD (computer aided diagnosis) plays a fair role in predicting the outcome of the treatment and planning of the therapy. Detection and segmentation of the cells are the important steps in a CAD. These steps are difficult due to touching cells, untidy background and variation in the shapes of the cell and changes inside the nuclei. In this paper, we present an analysis based on the textual features of the detected cell after the detection of the cell using adaptive dictionary selection and the sparse reconstruction technique with trivial template. The analysis is done on the basis of the first order and second order statistical features. The proposed method has been tested on a data set with 1000 cells extracted from 20 whole slide scanned images.

The salt (NEt 4 ) 2 [Fe 2 (CO) 8 ] reacts with (ClAu) 2 (μ-L) (L=bis(diphenylphosphino) methane (dppm), 1,2-bis(diphenylphosphino) ethane (dppe), 1,3-bis(diphenylphosphino) propane (dppp)) in tetrahydrofuran to yield [Fe 2 Au 2 (CO) 8 (μ-L)] (L=dppm, 2a; L=dppe, 2b; L=dppp, 2c). The structure of 2a has been determined by X-ray diffraction methods. 2a does not react with an excess of (NEt 4 ) 2 [Fe 2 (CO) 8 ], but 2b,c add another [Fe 2 (CO) 8 ] 2− fragment to give the hexametallic complexes (NEt 4 ) 2 [{Fe 2 Au(CO) 6 (μ-CO) 2 } 2 (μ-L)] (L=dppe, 3b; L=dppp, 3c), which are postulated to be formed by two Fe 2 Au units joined by an L ligand

Electrospinning uses a high voltage electric field to produce fine fibers. A new phenomenon of self-assembly in the electrospinning of polyurethane nanofibers is observed. This report is the first known self-assembling phenomenon in polyurethane electrospun nanofibers. Electrospun polyurethane nanofibers self-assemble into unique honeycomb patterns on the collector surface. This novel observation opens up new and interesting opportunities for electrospun fibers in the areas of drug delivery devices, protective clothing, filters, and tissue scaffolds. © 2006 Wiley Periodicals, Inc.

OBJECTIVE
To evaluate the complement system in cord blood and its relationship with the degree of maturation and intrauterine growth.
METHODS
Serum levels of C(3), C(4) and CH(50) were measured in premature, small for gestational age and appropriate for gestational age newborns. The activation of complement system was searched by clivage product determination C(3d) and C(4d). Serum IgG levels were also determined in all children.
RESULTS
The levels of C(3), C(4), CH(50) and IgG were significantly lower in preterm (p < 0,001); C(4) and IgG values were also significantly lower in small for date than those in normal newborn. C(3d) and C(4d) were not detected, indicating that the complement system had not been activated.
CONCLUSIONS
The lower complement component levels and IgG in newborn are related to gestational age as well as to intrauterine growth.

We construct, generalizing appropriately the method applied by J. Teschner in the case of the Virasoro conformal blocks, the braiding and fusion matrices of the Neveu-Schwarz super-conformal blocks. Their properties allow for an explicit verification of the bootstrap equation in the NS sector of the N = 1 supersymmetric Liouville field theory.

Abstract : The primary objective of this research program is to develop and apply mathematical tools for the purposes of process discovery. Our focus is on empirically based methods applied to massive data sets in a high-dimensional setting. The emphasis of the program is on applications of direct interest to the Air Force. In particular, we have been investigating problems of interest to Air Force Research Laboratory, Materials & Manufacturing Directorate, Materials Process Design Branch at Wright Patterson Air Force base. Lately, we have intended the work to a problem of interest to the United States Forest Service. Recent work includes the application of subspace noise reduction methods and their connection to blind source separation. We have established a theoretical connection between the maximum noise fraction method and independent component analysis and demonstrated the relationship with examples. This methodology has proven useful as an integral component of the Whitney Reduction Network, developed by the grantees. Additionally, a new approach for designing support vector machines has been developed for the classification problem using a kernel based Fisher discriminant method. In addition we have developed other algorithms in terms of kernel functions using a kernel Grim-Schmidt algorithm These techniques have been applied to the materials science bonding problem.

Zirconium (Zr) hydride and deuteride are considered as candidates of neutron reflector materials in fast reactors (FRs). Thus, it is important to evaluate their fundamental physical and chemical properties. In this study, we prepared ϵ-phase Zr deuteride (ϵ-ZrD1.90), whose physical properties have been investigated and also the heat capacity (CP) and thermal conductivity (κ) have been measured from room temperature to 673 K. The obtained data were compared with the literature data of δ-phase Zr hydride (δ-ZrH1.66), ϵ-phase Zr hydride (ϵ-ZrH1.94), and deuteride (ϵ-ZrD1.95). Both CP and κ of ϵ-ZrD1.90 were higher than those of δ-ZrH1.66. The higher CP of ϵ-ZrD1.90 than that of δ-ZrH1.66 is mainly due to the smaller vibration frequency of deuterium atoms than that of hydrogen atoms. On the other hand, the higher κ of ϵ-ZrD1.90 than that of δ-ZrH1.66 is due to the larger hydrogen isotope content of ϵ-ZrD1.90 than that of δ-ZrH1.66. The data reported here would be useful when Zr hydride and deuteride are installed into FRs.

Drugs are most commonly administered to patients as solid dosage forms given orally. Although this statement is less true in anaesthesia than in many other fields of medicine, a substantial amount of drug therapy prescribed by anaesthetists is given by mouth. It is often assumed that once a drug has been given by mouth it will be well absorbed and achieve its desired therapeutic effects. However, such a drug has to pass many barriers before it reaches the systemic circulation. The problems of poor biovailability of drugs are now well known, particularly in respect of digoxin (Johnson et al., 1973). We are now more aware of the properties a drug must possess in order to be absorbed and this article concentrates on these and other factors that influence the absorption.

Non-MALT marginal zone lymphoma regroups two subtypes of lymphoma, the splenic marginal zone lymphoma (SMZL) and the nodal marginal zone lymphoma (NMZL). Although they share a common cell of origin from the “marginal zone” (MZ), they display different clinical characteristics, reflecting probable biological variations according to the organ. Within the past decade, new data regarding pathogenic mechanisms as well as therapeutic advances have been reported. SMZL and NMZL often present with disseminated disease at diagnosis, with specific clinical presentation, SMZL with predominant enlarged splenomegaly and NMZL with disseminated nodal involvement. Diagnosis may be difficult among the small B-cell lymphomas, and criteria for diagnosis have been recently improved. The therapeutic approaches comprise splenectomy for SMZL, and immunochemotherapy for both of SMZL and NMZL, but with no consensus about the best treatment, except when associated with hepatitis C virus. This review addresses the current knowledge on the biological findings, clinical features, and therapeutic approaches for the individual SMZLs and NMZLs.

INTRODUCTION
The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) aimed to promote equitable access to safe childbirth and postnatal care through a community-based educational intervention. This study evaluates the extent to which MaNHEP reached women who are socially and materially disadvantaged and, thus, at high risk for inadequate access to care.
METHODS
The data used in this analysis are from MaNHEP's cross-sectional 2010 baseline and 2012 endline surveys of women who gave birth in the prior year. A logistic regression model was fit to examine the effects of sociodemographic characteristics on participation in the MaNHEP program. Descriptive statistics of select characteristics by birth and postnatal care provider were also calculated to explore trends in services use.
RESULTS
Using data from the endline survey (N = 1019), the regression model showed that age, parity, education, and geographic residence were not significantly associated with MaNHEP exposure. However, women who were materially disadvantaged were still less likely to have participated in the program than their better-off counterparts. From the baseline survey (N = 1027) to the endline survey, women's use of skilled and semiskilled providers for birth care and postnatal care increased substantially, while use of untrained providers or no provider decreased. These shifts were greater for women with less personal wealth than for women with more personal wealth.
DISCUSSION
MaNHEP appears to have succeeded in meeting its equity goals to a degree. However, this study also supports the intractable relationship between wealth inequality and access to maternal and newborn health services. Strategies targeting the poor in diverse contexts may eventually prove consistently effective in equitable services delivery. Until that time, a critical step that all maternal and newborn health programs can take is to monitor and evaluate to what extent they are reaching disadvantaged groups within the populations they serve.

Elevated intraocular pressure is the main risk factor in primary open-angle glaucoma, involving an increased resistance to aqueous humor outflow in the juxtacanalicular region of the conventional outflow pathway which includes the trabecular meshwork (TM) and the inner wall of Schlemm's canal (SC). Previously, sphingosine-1-phosphate (S1P) was shown to decrease outflow facility in porcine and human eyes, thus increasing outflow resistance and intraocular pressure. Owing to S1P's known effect of increasing barrier function in endothelial cells and the robust expression of the S1P₁ receptor on the inner wall of SC, we hypothesized that S1P₁ receptor activation promotes junction formation and decreases outflow facility. The effects of subtype-specific S1P receptor compounds were tested in human and porcine whole-eye perfusions and human primary cultures of SC and TM cells to determine the receptor responsible for S1P effects on outflow resistance. The S1P₁-specific agonist SEW2871 failed to both mimic S1P effects in paired human eye perfusions, as well as increase myosin light chain (MLC) phosphorylation in cell culture, a prominent outcome in S1P-treated SC and TM cells. In contrast, the S1P₂ antagonist JTE-013, but not the S1P₁ or S1P₁,₃ antagonists, blocked the S1P-promoted increase in MLC phosphorylation. Moreover, JTE-013 prevented S1P-induced decrease in outflow facility in perfused human eyes (P < 0.05, n = 6 pairs). Similarly, porcine eyes perfused with JTE-013 + S1P did not differ from eyes with JTE-013 alone (P = 0.53, n = 3). These results demonstrate that S1P₂ , and not S1P₁ or S1P₃, receptor activation increases conventional outflow resistance and is a potential target to regulate intraocular pressure.

Even when a performance is not billed as biographical or autobiographical, audiences intuit that the creator has drawn from lived “true” experience—either her own or someone else’s—in order to portray a resonant story. The potential presence of this truth is alluring and difficult, especially when a performance is acknowledged to be auto / biographical. On the one hand, it promises to reveal highly specific real-world data; on the other, it conjures a disruptive suspicion about fictions that may surround a nugget of perceived fact.

The paper presents an algorithm of the exact symbolic network function analysis that deals with circuits with any size. The only condition is to decompose the whole circuit into smaller subcircuits. The decomposition is the multi-level hierarchial one. What is more, the calculation for each level can be done only once. One can reuse the partial results any time when the previously determined subcircuit appears in any analyzed structure. A higher level subcircuit needs only a few information about internal structure of a lower level, so the method can be easily implemented in multiprocessor or distributed systems. Although multilevel and compressed structure, symbolical values remain cancelation-free and any path from the root to the terminal vertex 1 represents a single term. Thus, a large-scale and small-scale sensitivities calculation and elimination of less significant terms could be simply and natural.

Pressure loads are configuration dependent. The magnitude of the pressure may be considered as a function of the Eulerian or the Lagrangian coordinates respectively. The first (natural) case turns out to be conservative if a certain line integral vanishes; the second (artificial) one is always nonconservative. Basing on the theory of potential operators the condition for the conservativeness of a pressure loading acting on a finitely deformed structure is derived and the corresponding potential and incremental potential are calculated. They are needed for the variational principles of conservative elastic boundary value problems. In the nonconservative case the principle of virtual displacements and its incremental version respectively serve as an adequate description.
Druckbelastung ist konfigurationsabhangig. Die Grose des Drucks kann als Funktion der Eulerschen bzw, der Lagrangeschen Koordinaten betrachtet werden. Der erste (naturliche) Fall stellt sich als konservativ heraus, falls ein bestimmtes Linienintegral verschwindet; der zweite (kunstliche) ist immer nichtkonservativ. Ausgehend von der Theorie der Potentialoperatoren wird die Bedingung fur die Konservativitat einer Druckbelastung, die auf eine endlich verformte Struktur wirkt, hergeleitet. Ferner werden das dazugehorige Potential und inkrementelle Potential berechnet. Man benotigt diese in den Variationsprinzipien konservativer elastischer Randwertprobleme. fur den nichtkonservativen Fall sind das Prinzip der virtuellen Verschiebungen und seine inkrementelle Version adaquate Beschreibungen.

Although many public hospital physicians in Vietnam offer private service on the side, little is known about the magnitude and nature of the phenomenon so-called dual practice, let alone the dynamics between the public and private health sectors. This study investigates how and to what degree public hospital physicians engage in private practice. It also examines the commitment of dual practitioners to the public sector. The analysis is based on a hospital-based survey of 483 physicians at 10 public hospitals in four provinces of Vietnam. Nearly half of the participants in the study sample reported themselves as dual practitioners. Various types of private practice were mentioned. Private practice at health facilities owned by the private sector was the most prevalent, followed by private practice delivered at health facilities owned by the dual practitioners themselves. Private practice inside public hospitals was also noted. Dual practitioners were likely to be senior and hold management positions inside their public hospitals. Substantial income differences were found between dual practitioners and those physicians practicing exclusively in the public sector. The majority of dual practitioners, however, reported the willingness to give up private practice if certain conditions were met, such as a basic salary increase or non-pecuniary benefits. The main reasons dual practitioners gave for not leaving the public sector included a sense of public responsibility and opportunities to gain a broader professional network and more training. This study reiterates the significant challenges associated with dual practice, including its financial implications and possible effects on health care quality and access. The need for a high-quality workforce committed to the public sector is particularly critical, given the possibility of universal insurance coverage. Future research should address the need to improve data collection on physicians' dual practice and incorporate the topic in policy debates on health reform.

Exosomes from cancer cells, which contain microRNA and reach metastasis loci prior to cancer cells, stimulate the formation of a metastatic microenvironment. Previous studies have shown that exosomal miR-141-3p is associated with metastatic prostate cancer (PCa). However, the role and regulatory mechanism of miR-141-3p in the microenvironment of bone metastases require further study. In this study, we performed a series of experiments in vivo and in vitro to determine whether exosomal miR-141-3p from MDA PCa 2b cells regulates osteoblast activity to promote osteoblastic metastasis. We demonstrate that extracts obtained from cell culture supernatants contained exosomes and that miR-141-3p levels were significantly higher in MDA PCa 2b cell exosomes. Via confocal imaging, numerous MDA PCa 2b exosomes were observed to enter osteoblasts, and miR-141-3p was transferred to osteoblasts through MDA PCa 2b exosomes in vitro. Exosomal miR-141-3p from MDA PCa 2b promoted osteoblast activity and increased osteoprotegerin OPG expression. miR-141-3p suppressed the protein levels of the target gene DLC1, indicating its functional significance in activating the p38MAPK pathway. In animal experiments, exosomal miR-141-3p had bone-target specificity and promoted osteoblast activity. Mice injected with miR-141-3p-mimics exosomes developed apparent osteoblastic bone metastasis. Exosomal miR-141-3p from MDA PCa 2b cells promoted osteoblast activity and regulated the microenvironment of bone metastases, which plays an important role in the formation of bone metastases and osteogenesis damage in PCa. Clarifying the specific mechanism of bone metastasis will help generate new possibilities for the treatment of PCa.

Dense 3D reconstruction of the surrounding environment is one the fundamental way of perception for Advanced Driver-Assistance Systems (ADAS). In this field, accurate 3D modeling finds applications in many areas like obstacle detection, object tracking, and remote driving. This task can be performed with different sensors like cameras, LiDARs, and radars. Each one presents some advantages and disadvantages based on the precision of the depth, the sensor cost, and the accuracy in adverse weather conditions. For this reason, many researchers have explored the fusion of multiple sources to overcome each sensor limit and provide an accurate representation of the vehicle’s surroundings. This paper proposes a novel post-processing method for accurate depth estimation, based on a patch-wise depth correction approach, to fuse data from LiDAR and stereo camera. This solution allows for accurate edges and object boundaries preservation in multiple challenging scenarios.

TO THE EDITOR: I have read the Cleveland Clinic Journal of Medicine for many years and, by and large, have enjoyed the journal. I recently received, with my regular Journal, the special issue on coxibs—which, I felt, was a disgrace. It is often difficult enough to get honest data from reputable journals, but to foist upon me a series of articles written (with one exception) by physicians and researchers who are in the employ of drug companies or their affiliates discredits your journal and The Cleveland Clinic! Many of the articles sound like they came from the advertising departments of Merck et al. American medicine is having enough trouble without becoming the agent of pharmaceutical manufacturers.

AS the mechanization of industry has advanced it has been necessary to maintain a constant vigilance to protect the industrial worker and the general public against any accompanying hazards of injury and disease. Despite such precaution, occasionally it is only with time and experience that an unforeseen danger associated with the use of a mechanical device may become evident. Unless attention is promptly called to such a menace it is apt to receive slow recognition and belated correction, particularly if it is revealed by infrequent and isolated accidental occurrences. We believe such a situation to prevail with the powder-actuated tools . . .

There is a need for undergraduate medical training to bring students closer to the real clinical settings they will face early in their professional lives. This study aims to review and improve student interns’ experience in different clinical scenarios: primary health care; secondary outpatient clinic (a new rotation) and the emergency room of a tertiary hospital. This new rotation is an opportunity for students to see acutely ill patients before they are referred to the hospital. Following a 30-day period, the students’ perceptions were surveyed and, based on student records, a list of all the patients (and diagnoses) which they saw was composed. The final result was a list of clinical conditions from these three different scenarios. Students acknowledge that the new rotation added to their clinical learning, especially because it was based on non-referred patients. They also felt that 4 hours/week is not enough and asked for more time in this rotation. During their 30 days, 7 students performed 201 consultations, most of them in the primary health care setting. There was a wide variety of clinical cases, which was possible because the students rotate among those three settings. Some experiences were only possible due to the new outpatient clinic rotation, indicating how this approach offer complementary learning opportunities which should be institutionally valued.

Background: It is crucial that each and every stroke patient gets a systematic assessment of swallowing disorders, performed by a dysphagia specialist. Therefore, there is a need to use a standardized scale among professionals. The aim of this study was to translate, adapt, and obtain the statistical characteristics of the Functional Oral Intake Scale (FOIS), which is an observer-rated dysphagia severity scale primarily developed for stroke patients, into the Slovenian language.
Methods: We performed a 5-step translation and adaptation process. Six speech and language pathologists had evaluated 30 clinical records of patients with an acute ischemic stroke in the carotid artery territory with the Slovenian translation of the Functional Oral Intake Scale (FOIS-SI). Every clinical record included a speech and language clinical bedside assessment of dysphagia, the sex, age, National Institutes of Health Stroke Scale (NIHSS), comorbidities of patients and lesion location. We examined interrater and intrarater reliability and additionally convergent validity of FOIS-SI with the theoretically related IDDSI-Functional Diet Scale (IDDSI-FDS).
Results: The average measure Intraclass Correlation Coefficient (ICC) for the interrater reliability (ICC=0.959) and the intrarater reliability (ICC=0.979 and ICC=0.991) for both raters was excellent. The FOIS-SI scores correlated very high with the IDDSI-FDS (rs=0.927).
Conclusion: The results of this study show that the Slovenian translation of the FOIS has an excellent interrater and intrarater reliability and very high validity, which implies the FOIS-SI can be used as a tool to quantitatively assess the severity of dysphagia in clinical practice and research in patients with stroke in carotid artery territory across the country in all medical and care settings.

The outcome of an immune response is dependent on the interplay and complex interactions of positive (stimulatory) and negative (inhibitory) pathways and a major goal of modern immunology is to dissect these physiologic interactions in order to apply these physiologic mechanisms therapeutically. The balance of stimulatory and inhibitory signals is critical for maximizing the ability of the adoptive immune response to defend the host while maintaining immunologic tolerance and preventing autoimmunity. Cellular quiescence is a state characterized by decreased cell size and metabolic activity. The quiescent state of unstimulated T lymphocytes is thought to be due to the lack of activation signals. However, recent studies have shown that quiescence in lymphocytes is not a default state, but an actively maintained gene program. This program regulates intrinsic expression of quiescence factors in T lymphocytes. In addition to intrinsic mechanisms regulating T cell quiescence, CD4 + CD25 + regulatory T cells (Treg) naturally arising in the thymus, engage in the maintenance of immunological self-tolerance by preventing autoimmunity in vivo in a non cell-autonomous manner. Although there is still only a rudimentary knowledge of the molecular mechanisms that govern the activity of the intrinsic quiescence factors and the development of Treg, it is now clear that immune quiescence is regulated by constitutively ongoing active mechanisms.

OBJECTIVE
Capsaicin is a widely utilized experimental pain stimulus; however, few studies have reported on ethnic differences in pain responses to capsaicin. The present study used infrared thermography to 1) measure differences in capsaicin-induced neurogenic flare between non-Hispanic black (NHB) and non-Hispanic white (NHW) adults and 2) determine the association between neurogenic flare and secondary hyperalgesia.
METHODS
Fifty-four participants (NHB N = 28) underwent heat/capsaicin sensitization model procedures. Neurogenic flare was examined using experimenter (i.e., subjective) and thermography (i.e., objective) measurements. A typically nonpainful mechanical punctate probe was used to measure secondary hyperalgesia.
RESULTS
Ethnic groups did not significantly differ in age, sex, marital status, or personal income. Although experimenters rated a significantly wider area of capsaicin-related neurogenic flare among NHW compared with NHB participants (F1, 52 = 8.33, P = 0.006), thermography results showed no differences between groups in neurogenic flares (F1, 52 = 0.01, P = 0.93). Further, although NHB individuals reported greater average pain during the capsaicin procedures compared with NHW individuals (NHB = 58.57 [3.67], NHW = 46.46 [3.81]; F2, 51 = 5.19, P = 0.03), the groups did not differ in secondary hyperalgesia (F2, 51 = 0.03, P = 0.86), and ethnicity did not moderate the association between neurogenic flare and secondary hyperalgesia (F3, 50 = 0.24, P = 0.87).
CONCLUSIONS
Findings cautiously support the use of infrared thermography over subjective experimenter report when measuring neurogenic inflammation in diverse samples. However, infrared thermography should not be used as a diagnostic tool for pain, given the lack of association between these factors. Future research is warranted to replicate these findings in a larger and more diverse sample to determine accurate neurogenic inflammation measures across other ethnic minority populations.

Previous research has shown that judgments of learning (JOLs) made immediately after encoding have a low correlation with actual cued-recall performance, whereas the correlation is high for delayed judgments. In this article, the authors propose a formal theory describing the stochastic drift of memory strength over the retention interval to account for the delayed-JOL effect. This is done by first decomposing the aggregated memory strength into exponential functions with slow and fast memory traces. The mean aggregated memory strength shows power-function forgetting curves. The drift of the memory strength is large for immediate JOLs (causing a low predictability) and weak for delayed JOLs (causing a high predictability). Consistent with empirical data, the model makes a novel prediction of JOL asymmetry, or that immediate weak JOLs are more predictive of future performance than are immediate strong JOLs. The JOL distributions for immediate and delayed JOLs are also accounted for.

An important issue of multi‐channel multi‐radio wireless mesh network is how to assign multiple available channels to the radios in order to minimize the wireless communication interference and maximize the network throughput. In this work, we study the problem of channel assignment in MRMC‐WMN, and the optimization problem is known to be NP‐complete. We propose a novel dynamic channel assignment scheme, which is based on network coding (NC) and data flow. Our scheme can be performed in distributed manner and is suitable for both unicast and multicast communication. Compared with the basic dynamic CA scheme, the analysis and comparison demonstrates that our proposed scheme has less communication cost and less interference.

We propose a supply noise rejection technique, which is applied to an all-digital phase-locked loop (ADPLL). Supply noise is cancelled by adding a cancellation current whose fluctuation is the same as that of a supply-noise component in an oscillator current. The proposed technique is realized with a small area and current dissipation, and is tolerant to process, voltage, and temperature (PVT) variations without calibration. The proof-of-concept chip was fabricated using a 65 nm CMOS technology. It was measured that the peak-to-peak jitter was reduced by 54 % in the presence of 30 mVpp, 15 MHz supply noise, and the robustness of the proposed technique was verified by the measurements.

Commercial banks are typical hierarchical organizations, in which the multiple-principal-agent problem exists and induces serious internal collusive corruption. This article analyzes the collusive corruption between the credit supervisor and the credit manager in bank credit activities, through three possible situations of supervision and examination, including honest and costly supervisor alone, corrupt and costless supervisor alone, and the coexistence of both supervisors. The results of this paper indicate that it is still necessary for the internal supervisor to provide the supervision even though he could collude. Meanwhile, it is inefficient for the bank only depending on the costly external supervisor. Finally, some suggestions are also proposed.

Cytosolic superoxide dismutase (SOD) of the onion maggot, Delia antiqua, was purified to apparent homogeneity by ammonium sulfate fractionation followed by anion exchange, hydrophobic interaction, and gel filtration chromatographies. Native molecular mass was estimated as 32,000 daltons. SDS-PAGE revealed only one subunit of 16,000 daltons, indicating that SOD is a homodimer. Isoelectric focusing revealed 3 charge isomers of pls 5.3, 5.5, and 5.7. The specific activity of purified SOD was 4,250 U/mg protein. A monoclonal antibody (MAb, aSOD2B7) raised against Delia SOD recognized only SOD of the same genus, but another MAb (aSOD1H11) recognized SOD of Drosophila melanogaster as well. © 1995 Wiley-Liss, Inc.

Lynch syndrome (LS) is the leading cause of hereditary colorectal cancer (CRC). Germline mutations in DNA mismatch-repair (MMR) genes (MLH1, PMS2, MSH2, and MSH6) are known to cause LS in the heterozygous state. Biallelic mutations in these genes cause mismatch repair cancer syndrome (MMRCS), a very rare childhood cancer syndrome that predisposes to CRC among other cancer types. In this study, we aimed to characterize the mutational landscape of LS in a large CRC cohort (n=1,207) from a population with high rates of consanguinity. The overall contribution of germline mutations in LS gene was comparable to that observed in outbred populations (26/1207). Remarkably, however, we also observed the unusual homozygous occurrence of a founder PMS2 mutation. The homozygous individual presented with massive adenomatous polyposis of the colon at age 8 years, and mutation analysis of multiple polyps revealed the occurrence of multiple independent somatic APC mutations. Our study highlights a previously unrecognized role of LS genes in triggering APC-driven tumors, a phenomenon facilitated by consanguinity. Citation Format: Abdul K. Siraj, Sandeep K.

Certain events sometimes exert a decisive influence on the future direction of a person's life. In my case one of the more determinative occurred during a brief week spent in Vienna in early February 1957 For one thing, I discovered in the Haus-, Hof- und Staatsarchiv highly significant documents in some cartons that had just been returned to Austria from Italy, by mistake as it turned out. The director of the Austrian archives, Gebhard Rath, put these records at my disposal. These papers, together with material of lesser import in the Archivio di Stato in Milan, provided the documentation for an article showing how Austrian officials had thwarted the efforts of an Italian scoundrel to extort money from them. More important than this discovery were my conversations with Professor Hugo Hantsch, of the University of Vienna, during the course of which I promised to supply as complete a list as possible of United States and Canadian writings on the history of the Habsburg monarchy, take the initiative in founding some kind of association for American scholars interested in Habsburg and Austrian history, and endeavor to help the Austrian professor obtain a grant from the Ford Foundation for a large international project on the history of the Habsburg monarchy from 1848 to 1918.

We report a new radio-frequency (RF) phase stabilization approach for long-haul optical fiber distribution. The phase drift of an RF signal induced by fiber-length variations can be canceled out automatically via RF mixing without using active phase discrimination and dynamic phase tracking. A key significance of our approach is that no assistant local oscillator (LO) signal is needed. Consequently, frequency estimation of the received RF signal, as well as frequency locking between the LO and the received RF signal, is no longer required, which simplifies the system. A proof-of-concept experiment shows that the phase drift of the received RF signal at 9.6 GHz is significantly reduced using the proposed method. The root mean square (RMS) timing jitter is 0.76 ps when a tunable optical delay line (TODL) inserted between the remote antenna unit (RAU) and local station is changed from 0 to 300 ps.

This study aims to evaluate the immunomodulatory effect of traditional drink of black cincau-based wedang uwuh (WUB) on alloxan-induced diabetic rats.,WUB consists of dried herbs such as black cincau leaves (Mesona palustris BL), red ginger (Zingiber officinale Rosc), cloves (Syzgium aromaticum), sappan wood (Caesalpinia sappan Lin) and soursop leaves (Annona muricata). In this study, the rats were divided into five groups: normal control, diabetic control and three groups of WUB (WUB 13.5 mL/kg and WUB 27 mL/kg) or wedang uwuh commercial (WUC) treated diabetic groups. WUB or WUC was administered by gavage for three days after rats were confirmed diabetic induced by alloxan; these injections were continued for 28 days. At the end of the experiment, the spleen of rats was analyzed using flow cytometry. Data were analyzed by ANOVA followed by Tukey test using Minitab version 16.0.,This study showed that WUB significantly inhibited the expression of pro-inflammatory cytokines (interferon-Y [IFN-ɣ] and tumor necrosis factor-α [TNF-a]) and anti-inflammatory cytokines (interleukin 10 [IL-10] and transforming growth factor-β [TGF-s]), and achieved a balance between pro-inflammatory and anti-inflammatory cytokines that were not significantly different from normal controls. WUB 27 was able to regulate the production of relative average cytokines IFN-ɣ (7.6 ± 3.5; p = 0.010), TNF-a (8.7 ± 2.4; p = 0.018), IL-10 (6.3 ± 2.4; p = 0.001) and TGF-s (7.4 ± 2.1; p = 0.004) that was significantly different from diabetic control. This study’s results validate that the use of WUB can result in immunomodulatory activity in diabetic rats.,To the best of the authors’ knowledge, this is the first study on the immunomodulatory effect of WUB which is developed based on WUC; WUB has been used by Indonesian people as a functional beverage which acts as an immune booster and body warmer.

A total of 44 countries is considered here for the analysis. Overall, the level of population aging in 2012 is low in sub-Saharan Africa, around 5%. More than one third (38.6%) of the countries show more than 100% increase in the proportion of 60+ population by 2050. About 28% of the countries have a growth rate of 50% or less. The regional variations within sub-Saharan Africa show that the eastern and southern regions have more growth potential as far as population aging is concerned. No doubt, in sub-Saharan Africa, poverty among older persons is higher than that of the rest of the population. However, 55% of the countries in sub-Saharan Africa have a real GDP growth of more than 5%. Further, a large number of sub-Saharan countries are projected to experience high and increasing economic support ratios for years or decades to come, and can therefore benefit significantly from the ‘demographic dividend’ brought in by the ongoing age structural transition. Thus, with higher GDP growth levels and hence reduction in poverty, higher educational levels and changing life styles including independent living, we can reasonably expect increased scope for the utilization of gerontechnology in the coming decades, at least in a limited way.

The amplitude and phase of zero‐frequency cyclotron waves induced by an accelerating gap in an electron‐beam accelerator are calculated. Using Fourier‐transform techniques, the amplitude is found to be directly related to the Fourier transform of the radial electric field. A simple field model reflects the basic physics of the gap and is used to find closed form solutions to the oscillation equations. A formal solution for suppressing oscillations over a finite energy range is also found.

To solve the pollution problem of electromagnetic waves, new electromagnetic shielding materials should meet the requirements of being lightweight with high electrical conductivity. In this work, the combination of silver (Ag) nanoparticles and nitrogen doping (N-doping) was expected to tune the electromagnetic and physical properties of Ti3C2Tx MXene, and the Ag@N-Ti3C2Tx composites were fabricated through the hydrothermal reactions. The nitrogen doped (N-doped) Ag@Ti3C2Tx composites showed a hollow structure with a pore size of 5 μm. The influence of N-doped degrees on the electromagnetic interference (EMI) shielding performance was investigated over 8–18 GHz. Therefore, the controlled N-doping composites exhibited reflection-based EMI shielding performance due to the electrical conductivity and the special three-dimensional (3D) honeycomb-like structure. The achieved average EMI shielding values were 52.38 dB at the X-band and 72.72 dB at the Ku-band. Overall, the Ag@N-Ti3C2Tx foam, due to its special 3D honeycomb-like structure, not only meets the characteristics of light weight, but also exhibits ultra-high-efficiency EMI shielding performance, revealing great prospects in the application of electromagnetic wave shielding field.

Abstract Truncation error estimates are considered as criteria for fine-grid placement and movement in nested and adaptive finite-difference atmospheric models. A simple method for calculating the truncation error at any time during an integration is described. Two cases using the shallow-water equations and the hydrostatic primitive equations are examined to demonstrate the accuracy of the method and illuminate the relationships among the truncation error, a particular discretization, the equations being solved and the flow physics. The relationship between the truncation error and the solution error is also discussed and it is argued that minimization of the truncation error is the necessary consideration for producing more accurate numerical solutions. Examples of use of the truncation error estimates in adaptive models are also presented.

Contact-dynamics simulations are increasingly being used in industry for enhancing product design and operation. Simulation accuracy depends not only on the simulation tools (i.e., formulation, algorithms, and computer codes) but also on the model parameters used in the simulation. Determination of contact-dynamics model parameters for a complex dynamic system is challenging. It is desirable to have a systematic method which can identify multiple model parameters directly from the physical test of the involved contact hardware. This paper describes a robotics-based experimental testbed which is specially designed for study and verification of a systematic method of identifying key parameters of multiple-point contact-dynamics models. The identification method can identify the stiffness, damping, and friction parameters all together from system-level hardware tests. The basic requirements of the testbed and how they are met by the design of the testbed are described. Some results of the preliminary test of the testbed obtained so far are also included.Copyright © 2007 by ASME

The skeletal muscle contraction is transmitted to the tendon through the myotendinous junction (MTJ), where the proximal extremity of tendon forms characteristic finger-like processes, penetrating into the muscle mass (Ciena et al., 2010). MTJ represents an intriguing and complex structure from both biological and functional point of view. We recently demonstrated that changes at MTJ level occur as an adaptation to exercise-induced tension increase. In particular, branching of finger-like processes increases, so enlarging the whole tendon-muscle surface area and, consequently, allowing a better tension resistance (Curzi et al., 2012). The aim of this study is to analyse MTJ behavior in disuse condition, furtherly investigating the strict morphofunctional correlation. Therefore, 4 hind-limb suspended and 4 control rats were studied. After sacrifice, MTJs of plantaris muscle were withdrawn, fixed in 1.4% glutaraldehyde in 0.2M sodium cacodylate and processed as previously described (Tidball et al., 1992; D’Emilio et al., 2010). After 5 days of suspension, skeletal muscle highlights signs of atrophy in response to decreased mechanical loading (Linderman et al., 1994). In fact, close to muscle-tendon interface, irregular misaligned sarcomeres, with absent Z-lines, were observed. Muscle intermyofibrillar component spreads, especially between terminal filaments and tendon finger-like processes. A lower number of muscle-tendon interdigitations, characteristically not bifurcated, also appears. In conclusion, along with muscle atrophy features, ultrastructural changes occur at the MTJ organization level, as an adaptation to muscle unloading.

For segmenting the target lesions accurately in CT images of cerebral hematoma, this paper proposes a spatial and multi-scale neural network segmentation model (MSHA-Unet). The model fuses the semantic information of the top and bottom layers of images in the same level by multi-kernel convolution, and fuses the attention mechanism in multi-scale feature images by jumping connection, so as to accurately locate and segment cerebral hematoma in medical CT images. To verify the effectiveness of the model, the experiment was carried out on 3716 CT images of 81 cases of cerebral hemorrhage, and the model was compared with six neural network models. The experimental results were measured by various evaluation standards, and showed that the model was superior to other network models.

The resolution of overlapping bands in the UV-Vis absorption spectra leading to determination of their basic parameters () provides important information about the energies and probabilities of the electronic transitions. In the analysis of UV-Vis absorption spectra recorded linearly in wavelength by means of modern spectrophotometers with holographic gratings, the analytical shape describing individual bands is asymmetric. This factor leads to certain limitations in determining their number with the use of the second-derivative spectra and decreased effectiveness of the computing procedure. It was found that the loss of information in d2A/dλ2 is due to its long-wavelength attenuation in comparison with d2A/dν˜2. An analytical equation connecting d2A/dλ2 with d2A/dν˜2 is proposed, which restores the information from the second derivative in the long-wavelength region.

The tenth anniversary edition of the biennial roadmap is the first edition under our new name: International Electronics Manufacturing Initiative (iNEMI). The nineteen technology roadmaps identify future research, development, and implementation needs to continue the growth of the worldwide electronics industry. During this roadmap cycle, we consciously targeted participation from key Asian and European firms/organizations in order to help insure that the technology projections truly represent a global view. With this roadmap we established an international collaborative agreement with the IEEE / CPMT (Institute of Electrical and Electronics Engineers / Components, Packaging and Manufacturing Technology), while continuing our strong linkages with other international roadmapping organizations - ITRS, IPC, IMAPS, INSIC, SCC, and OIDA- and with USDC. The 2004 iNEMI Roadmap consists of over 1200 pages, with more than 470 participants from over 220 companies, universities and associations from 11 countries. This paper highlights technology needs, paradigm shifts, strategic concerns, and key recommendations from the roadmap. Emphasis is placed on the advanced packaging, sensors, system in package, and organic and ceramic substrate roadmap chapters. This roadmap has increased the focus on forecasting potentially disruptive technology in the 2012-2015 time frame such as the use of nanotechnology to address the projected end of Moore's law and the scaling of CMOS devices. This roadmap balances the market needs against the future technology capabilities. The 2004 iNEMI Roadmap is a valuable snapshot of our industry in the third millennium. The challenge now shifts to leveraging these findings for the good of the electronics manufacturing supply chain

Three Japanese tree lilac (Syringa reticulata) cultivars, 2 each in 11 communities, were planted for evaluation as street trees. Cooperators in the Municipal Tree Restoration Program using standardized methods measured them annually for 3 years, and periodically afterwards. 'Ivory Silk', 'Regent', and 'Summer Snow' performed well at all locations. All 3 cultivars grew slowly initially, and their foliage tended to turn yellow in late summer.

Breadfruit is a nutritious, high energy food with a low quantity of protein but excellent protein quality. It has the potential to be developed into desired products which will help increase its utilization and add value to the crop. The overall purposes of this investigation were to develop a portable, nutritious, ready-to-eat breadfruit product (bar), test the sensory qualities of the product, and evaluate the nutritional properties of the product. Flour made from the Micronesian variety, Meinpadahk (Artocarpus altilis × Artocarpus mariannensis), was utilized for the development of the breadfruit bar. Breadfruit is a rich source of fiber, vitamins such as vitamin C, minerals such as potassium, and phytochemicals such as flavonoids. Nutritional labeling indicates that the breadfruit bar is high in carbohydrates and low in fat, and sensory evaluation indicates that 81% of the panelists found the bar acceptable while 19% disliked the bar. The breadfruit bar can provide an appealing and inexpensive gluten-free food source based on locally available breadfruit.

It is seldom recognized that men and women have different interests in production, access to and use of resources for agricultural production. The resources they use in their production processes are very vital, due to their limited supply and stiff competition for them by many other enterprises, and as such needed to be properly utilized to increase production in a sustainable manner. This work was therefore conducted in Akwa Ibom state to examine factors influencing the technical efficiency of farmer groups in cassava production. In carrying out the study, 120 respondents were randomly selected from two agricultural zones in the State and interviewed with interview schedule. Data were analyzed using descriptive and inferential statistics. The results showed that more of the female farmers than the male were in their active and productive ages, had more farming experience while the males were more educated. Labour, fertilizer and capital input had positive and significant effects on the output of the male farmers while farm size, cassava cutting, fertilizer, capital input and other input (such as herbicides, poultry manure, depreciated cost of fixed farming equipment such as hoe, knife etc.) had positive and significant effects on that of the females. Membership of cooperative, extension contact, age, and farm size significantly influenced the technical efficiency of the male farmers while land ownership, house hold size, education, farming experience and farm size had significant and positive influence on that of the females. The results further revealed that the farmer groups were not technically efficient in cassava production even though the males were found to be more technically efficient than their female counterparts. Key words : gender, factors, technical efficiency, cassava farmers

Having taken taking as one of its starting points a concern to avoid fetishising method – or employing any form of method for its own sake – this paper then argues that visual methods of research may be particularly helpful in investigating areas that are difficult otherwise to verbalise or articulate. These include Bourdieu's understanding of habitus; our predisposed ways of being, acting and operating in the social environment that Bourdieu himself suggests are ‘beyond the grasp of consciousness, and hence cannot be touched by voluntary, deliberate transformation, cannot even be made explicit’ (Bourdieu, 1977: 94). Having outlined what Bourdieu means by habitus and considered some of the difficulties surrounding its operationalisation, the paper goes on to consider Bourdieu's own use of photography and understanding of photographic practice. It is then argued that we can move beyond Bourdieu's position by employing visual methods specifically to uncover and illuminate aspects of habitus. Where research participants are directly involved in this process this also means that visual methods can be potentially transformative, allowing for the development of forms of critical self-awareness amongst research participants of the sort that Bourdieu attributes to ‘socioanalysis’ (Bourdieu, 1999: 611).

The aim of this research was to empirically understand role of family type and mother's occupation in determination of resilience among adolescent school goers. Standardized measure of resilience was administered upon 260 school adolescents from Aligarh district in Uttar Pradesh. The voluntary participants belonged to age group 14–18 years (Mean Age=16.62 years). 181 respondents were from nuclear families while 79 were joint families. Major proportion (70%) of respondents had mothers who were homemakers. Multivariate ANOVA was performed to examine the effects of family type and mothers’ working statuses. Results revealed significant main effects and interaction effects of the two variables on resilience and most of its dimensions. Results revealed that adolescents whose mothers were homemakers had relatively similar resilience scores (mostly high) irrespective of their family types. Adolescents from joint families with working mothers scored higher on resilience measure. In contrast, those with working mothers but from joint families had very low resilience scores. This study therefore throws light on the kind of impact family system can have on the adversity management strategies opted by the youth. Probably, working mothers from nuclear families enjoy more autonomy and have higher self esteem both of which can have positive influence on personality development and stress coping strategies of their children. In contrast this may not be the case for adolescents from joint family system and with working mothers as the latter may have to adhere to and adjust with principles related to child rearing.

Health care waste is produced from a number of activities performed in different areas of health care facilities. If it not disposed properly, poses serious threat to public health and to the environment. Hence an attempt is made to study the present state of health care waste management in Warangal and to determine awareness level, practices and the attitude towards it. This study was done in Warangal city. Category 1, 4, 7 wastes were segregated by 35%, 43%and 30% of the health care centres respectively. The final disposal options were present only in medical college teaching hospital. the management of category 8 waste, the underground drainage system was observed in 55% health care centres. Most of the health care centres not practiced disinfection before final disposal. Out 40 health care centres, 70% were manually transporting the waste to the site of final disposal. Only 30% centres were using containers and trolleys for transportation of waste. 35% health care centres burn the waste in the open field and 42% centres throw the waste indiscriminately around their premises. Only 8% health care centres use incineration as disposal option and another 5% use burial as disposal option. 20% centres dump the waste in public bin.

sigma-1 Receptors have been identified in numerous brain regions, including areas such as hypothalamus and amygdala, which have long been linked to the regulation of aggression. However, there is no clear information with respect to the possible effects of sigma-1 ligands on aggressive behavior in laboratory animals. Consequently, the present study examined the effects of (+)SKF 10047 (0.5-6 mg/kg, i.p.), a sigma-1 prototypical agonist, on isolation-induced aggression in male mice, using an ethopharmacological approach. Individually housed mice were exposed to anosmic "standard opponents" 30 min after drug administration. Ten minutes of diadic interactions were staged between a singly housed and an anosmic mouse in a neutral area. The encounters were videotaped, and the accumulated time allocated by subjects to 10 broad behavioral categories was estimated using an ethologically based analysis. Results showed that (+)SKF 10047 (6 mg/kg) produced a significant reduction of offensive behaviors, without affecting immobility. Social investigation behaviors were also slightly increased after drug treatment (2-6 mg/kg). These results suggest a role for sigma-1 receptors in aggression modulation in mice.

In the last two decades, there exist many high-performance prediction-based methods that use different coefficients of causal neighbors in order to exploit the relationship of spatial energy to produce a less error image. Besides, more and more researches focus on the accuracy of predictor; nevertheless, the predictor spends a lot of time on finding the best coefficients of causal neighbors. The objective of our research is to propose an efficient and implementable method to improve compression ratio, without increasing extra computation complexity. Here, we present an improved lossless image compression based on the prediction method, by the proposed application of efficient error value centralization by sign bits. The contribution of this paper is to centralize error values in a novel way to improves coding performance. Experimental results show that our proposed method achieves higher compression ratio than the context-based, adaptive, and lossless image codec (CALIC) method for the images with many details or slightly regular texture.

The effects of high pressure on lattice stability, mechanical and thermodynamic properties of L12 structure Al3Tm and Al3Lu are studied by first-principles calculations within the VASP code. The phonon dispersion curves and density of phonon states are calculated by using the PHONONPY code. Our results agree well with the available experimental and theoretical values. The vibrational properties indicate that Al3Tm and Al3Lu keep their dynamical stabilities in L12 structure up to 100 GPa. The elastic properties and Debye temperatures for Al3Tm and Al3Lu increase with the increase of pressure. The mechanical anisotropic properties are discussed by using anisotropic indices AG, AU, AZ, and the three-dimensional (3D) curved surface of Young's modulus. The calculated results show that Al3Tm and Al3Lu are both isotropic at 0 GPa and anisotropic under high pressure. In the present work, the sound velocities in different directions for Al3Tm and Al3Lu are also predicted under high pressure. We also calculate the thermodynamic properties and provide the relationships between thermal parameters and temperature/pressure. These results can provide theoretical support for further experimental work and industrial applications.

Article history: Received: 11 June, 2020 Accepted: 23 July, 2020 Online: 12 October, 2020 This paper is an extension of Novel Flexible Chip-less Bow-Tie RFID tag in which we presented the design, testing and fabrication of the tag and compared the results with Octagonal Chipless RFID tag. The chipless RFID tag was designed by using simulation software CST microwave studio and fabricated by using laser etching technique on a flexible polymer substrate Polyethylene Terephthalate (PET). The tag operates at frequency ranging from 8 to 18 GHz uses the Frequency Selective Surface (FSS) approach. A series of experiments are performed to measure the Radar Cross Section (RCS) in an anechoic chamber. The tag design is composed of six concentric Bow-Tie shaped loop resonators with one unitary element. In this paper, we demonstrated the Singularity Expansion Method (SEM) based circuit modelling and the transient behaviour of the RFID tag is performed. The coupling coefficients and the induced currents over the surface of Bow tie shaped rings are evaluated. The maximum read range is evaluated and the BowTie RFID tag is proved to be more accurate and efficient with the variation of distance up to 1.8m at 0dBm which is extendable to 2.14m for higher input power. This range is maximum to our knowledge for such a high-frequency range of 8-18GHz. The 4-bits BowTie Chipless RFID tag design is compact and can be deployed commercially for general IoT applications.

Flowering and nectar release in Acer pseudoplatanus were investigated between 2011 and 2013. The micromorphology of the floral and nectary elements was observed using a scanning electron microscope and the anatomy of nectaries was examined by light microscopy. The inflorescence of the sycamore was found to contain flowers, which were functionally male or functionally female. The life-span of the former was on average 5 days, whereas the latter lived on average 4 days. Both types of A. pseudoplatanus flowers had yellow-green nectaries with a similar structure. The nectary tissue formed an elliptical or circular layer located on the receptacle surface between the petals and the pistil. The filament bases were located within the nectary recesses but were not fused with this organ. The nectary margins were slightly undulated. The outer diameter of the nectary was in 3.0–3.25 mm and the thickness of the nectary tissue was in the range of 532–1,023 μm. The nectary of the sycamore flower comprised a single layer of epidermal cells and several layers of secretory parenchyma cells. The average depth of epidermal cells was 16.8 μm. The stomata, which were involved in the secretion process, were arranged unevenly on the nectary surface and were surrounded by six–eight epidermal cells. Visible droplets of nectar accumulated on the nectary surface and thus they were easily accessible to insects. The average weight of nectar from 10 flowers was 16.54 mg (range: 11.0–23.75 mg) and the content of sugars in the nectar was found to be in the range of 23.5–50%, with an average of 37.3%. The calculated weight of sugars in the nectar from 10 flowers was on average 6.11 mg and so the average sugar yield from one sycamore tree was estimated to be 0.65 kg.

We analyze the evolution of the ultrahigh-energy cosmic-ray spectrum upon traversing the 2.7 \ifmmode^\circ\else\textdegree\fi{}K microwave background with respect to pion photoproduction, pair-production reactions, and cosmological effects. Our approach employs exact transport equations which manifestly conserve nucleon number and embody the laboratory details of these reactions. A spectrum enhancement appears around 6\ifmmode\times\else\texttimes\fi{}${10}^{19}$ eV due to the ``pile-up'' of energy-degraded nucleons, and a ``dip'' occurs around ${10}^{19}$ eV due to combined effects. Both of these features appear in the observational spectrum. We analyze the resulting neutrino spectrum and the effects of cosmological source distributions. We present a complete model of the ultrahigh-energy spectrum and anisotropy in reasonable agreement with observation and which predicts an observable electron-neutrino spectrum.

ABSTRACT Rapid antibiotic susceptibility testing is in high demand in health care fields as antimicrobial-resistant bacterial strains emerge and spread. Here, we describe an optical screening system (oCelloScope) which, based on time-lapse imaging of 96 bacteria-antibiotic combinations at a time, introduces real-time detection of bacterial growth and antimicrobial susceptibility with imaging material to support the automatically generated graphs. Automated antibiotic susceptibility tests of a monoculture showed statistically significant antibiotic effects within 6 min and within 30 min in complex samples from pigs suffering from catheter-associated urinary tract infections. The oCelloScope system provides a fast high-throughput screening method for detecting bacterial susceptibility that might entail an earlier diagnosis and introduction of appropriate targeted therapy and thus combat the threat from multidrug-resistant pathogenic bacteria. The oCelloScope system can be employed for a broad range of applications within bacteriology and might present new vistas as a point-of-care instrument in clinical and veterinary settings.

ABSTRACT The authors present the initial validation of a romantic relationship motivation scale, enabling the level of self-determined involvement in romantic relationships during adolescence to be examined. The inclusion of Self-Determination Theory (E. L. Deci & R. M. Ryan, 2000) in the motivational constructs enhances the developmental perspective regarding adolescent romantic involvement. The scale was administered to 284 adolescents (163 girls and 121 boys, age 14–19 years) with a self-esteem scale and some questions about their romantic experiences to provide some elements of external validation. The results confirmed the 4-factor structure: intrinsic motivation, identified regulation, external regulation, and amotivation, which follow the self-determination continuum, previously highlighted in friendship motivation. As hypothesized, adolescents became more self-determined with age and girls were more self-determined than boys. Other findings show specific links between motivation for romantic relationships, self-esteem and romantic experiences. It highlights the importance of considering adolescents’ motivations when exploring their romantic relationships.
