Analysis of the Impedance Behaviour for Broadband Dipoles in Proximity of a Body Tissue: Approach by Using Antenna Equivalent Circuits

Ultra wideband (UWB) antenna operation close to tissue is examined by using lumped- element equivalent circuits in the present paper. The impact of tissue within the reactive near-fleld of the antenna is introduced in terms of e-ciency, impedance and matching to 50›. The parasitic components for the series- and parallel-resonant stages of the equivalent models are proposed for taking the impact of tissue into account on the antenna design. The flrst time the antenna impedance behaviour is presented in terms of capacitance, inductance and resistance as a function of the radiator distance on the tissue surface for UWB antennas. The capacitance was observed to increase with the distance on the tissue surface by achieving the maximum value close to the reactive near-fleld boundary. The inductance has the maximum on contact the tissue, decreasing strongly with the flrst millimetres and remaining constant with the higher distance. The maximum value of input resistance was seen to clearly increase with the distance, having the maximum value in the flrst third of the studied range, descending close to the value in free space at the boundary at the end. The results are achieved by realising electromagnetic simulations for the antennas and comparing the performance with the operation of the equivalent models.
Resource Allocation in Couples. A Collective Model with Prior Information

This paper approaches, for the first time, the estimation of a collective household demand system from a Bayesian perspective. Using prior information on equivalence scales, as well as restrictions implied by theory, tight credible intervals are found for resource shares, a measure of the distribution of economic well-being in a household. A modern MCMC sampling method provides a complete picture of the high-dimensional parameter vector's posterior distribution and allows for reliable inference. The share of household earnings generated by a household member is estimated to have a positive effect on her share of household resources in a sample of couples from the US Consumer Expenditure survey. An increase in the earnings share of one percentage point is estimated to result in a shift of between 0:05% and 0:14% of household resources in the same direction, meaning that spouses partially insure one another against such shifts. The estimates imply an expected shift of 0:71% of household resources from the average man to the average woman in the same sample between 2008 and 2012, when men lost jobs at a greater rate than women.
Violence, trust, and trustworthiness: evidence from a Nairobi slum

We test with a field experiment in a Nairobi slum whether violence suffered during the 2007 political outbreaks affects trustworthiness when interethnicity becomes salient and participants face opportunism in common pool resource games (CPRGs) between two subsequent trust games (TGs). Our findings do not contradict previous one-shot results but qualify and extend them to a multi-period setting, enriching our understanding of the effects of violence on social preferences. More specifically, the victimized exhibit higher trustworthiness in the first trust game but also a significantly stronger trustworthiness reduction after experiencing opportunism and interethnicity in the CPRG game.

A novel BCI-SSVEP based approach for control of walking in Virtual Environment using a Convolutional Neural Network

A non-invasive Brain Computer Interface (BCI) based on a Convolutional Neural Network (CNN) is presented as a novel approach for navigation in Virtual Environment (VE). The developed navigation control interface relies on Steady State Visually Evoked Potentials (SSVEP), whose features are discriminated in real time in the electroencephalographic (EEG) data by means of the CNN. The proposed approach has been evaluated through navigation by walking in an immersive and plausible virtual environment (VE), thus enhancing the involvement of the participant and his perception of the VE. Results show that the BCI based on a CNN can be profitably applied for decoding SSVEP features in navigation scenarios, where a reduced number of commands needs to be reliably and rapidly selected. The participant was able to accomplish a waypoint walking task within the VE, by controlling navigation through of the only brain activity.

Influenza virus A ( H 1 N 1 ) 2009 antibody-dependent cellular cytotoxicity in young children prior to the H 1 N 1 pandemic

Pre-existing immunity played a significant role in protection during the latest influenza A virus H1N1 pandemic, especially in older age groups. Structural similarities were found between A(H1N1)2009 and older H1N1 virus strains to which humans had already been exposed. Broadly cross-reactive antibodies capable of neutralizing the A(H1N1)2009 virus have been implicated in this immune protection in adults. We investigated the serological profile of a group of young children aged 9 years (n=55), from whom paired blood samples were available, just prior to the pandemic wave (March 2009) and shortly thereafter (March 2010). On the basis of A(H1N1)2009 seroconversion, 27 of the 55 children (49%) were confirmed to be infected between these two time points. Within the non-infected group of 28 children (51%), high levels of seasonal antibodies to H1 and H3 HA1 antigens were detected prior to pandemic exposure, reflecting past infection with H1N1 and H3N2, both of which had circulated in The Netherlands prior to the pandemic. In some children, this reactivity coincided with specific antibody reactivity against A(H1N1)2009. While these antibodies were not able to neutralize the A(H1N1)2009 virus, they were able to mediate antibody-dependent cellular cytotoxicity (ADCC) in vitro upon interaction with the A(H1N1)2009 virus. This finding suggests that cross-reactive antibodies could contribute to immune protection in children via ADCC.
Marketing channels used by wholesale and retail nursery companies.

Analysis of data collected from a questionnaire survey of randomly selected Tennessee nursery businesses revealed that wholesalers and retailers differed significantly in their stated reasons for attending and participating in industry trade shows. When controlled for business size (gross sales), wholesalers and retailers also differed significantly in their perception of the usefulness of catalogs, newspapers, trade journals, trade shows, and radio to advertise nursery products and services.
The WTO and the EU: Leadership versus Power in International Image

This EuroBroadMap working paper focuses on how the European Union (EU) is perceived in the World Trade Organization (WTO) negotiating system. Based on relevant academic literature, this paper examines the 'actorness' of the EU via two negotiation cases: one related to the 'Banana war', the other one related to MGO. It appears that the EU economic power is barely translated into leadership.
EMPHASIZING SOCIAL ISSUES TOWARD SUSTAINABLE SUPPLY CHAIN: A BRAZILIAN PERSPECTIVE

From sustainability perspective, the supply chain management strategy can use different indicators related to Triple Bottom Line to improve its practices. Some studies in the topic have focused only environmental issues; however in some cases the social issues should be considered as a core of the sustainable strategies. Considering this view, the paper aims to highlight the relevance of social issues in the Brazilian context toward sustainable supply chain. Therefore, a theoretical essay was conducted using the literature about sustainable supply chain in relation to the Brazilian perspective to understand how it is possible to use new approaches for a more emphasis on social issues. The discussions indicates that to re-conceptualize the social relations in supply chains, it's necessary to use corporate social responsibility and social capital approaches to create a better discussion about sustainable supply chain. The proposal starts a discussion in the Brazilian context to stimulate new scholars to study this topic.

The endothelial glycocalyx forms a continuous coat over the luminal surface of all vessels, and regulates multiple vascular functions. The contribution of individual components of the endothelial glycocalyx to one critical vascular function, microvascular permeability, remains unclear. We developed novel, real-time, paired methodologies to study the contribution of sialic acids within the endothelial glycocalyx to the structural and functional permeability properties of the same microvessel in vivo. Single perfused rat mesenteric microvessels were perfused with fluorescent endothelial cell membrane and glycocalyx labels, and imaged with confocal microscopy. A broad range of glycocalyx depth measurements (0.17–3.02μm) were obtained with different labels, imaging techniques and analysis methods. The distance between peak cell membrane and peak glycocalyx label provided the most reliable measure of endothelial glycocalyx anatomy, correlating with paired, numerically smaller values of endothelial glycocalyx depth (0.078±0.016μm) from electron micrographs of the same portion of the same vessel. Disruption of sialic acid residues within the endothelial glycocalyx using neuraminidase perfusion decreased endothelial glycocalyx depth and increased apparent solute permeability to albumin in the same vessels in a timedependent manner, with changes in all three true vessel wall permeability coefficients (hydraulic conductivity, reflection coefficient, and diffusive solute permeability). These novel technologies expand the range of techniques that permit direct studies of the structure of the endothelial glycocalyx and dependent microvascular functions in vivo, and demonstrate that sialic acid residues within the endothelial glycocalyx are critical regulators of microvascular permeability to both water and albumin.
Optimal controlled ALOHA for two-way data communication in a cable television network

Based on a unified analysis of both pure and slotted ALOHA systems, a new control algorithm for ALOHA systems is proposed. A feature of great practical importance is the algorithm's automatic adjustment to changes in average traffic intensity or the (finite or infinite) number of active stations in the system. In addition, the algorithm has a low-complexity implementation. Computer simulations, concentrating on the use for two-way data communication in a cable television network, have demonstrated that the practical performance of the algorithm closely approximates the theoretical optimum, even under extremely heavy traffic load conditions. Furthermore, dynamic performance simulations have shown that the algorithm assures swift recovery from overload situations. >
CONTROLLING FEEDING AND PSYCHOPATHOLOGY 1 CONTROLLING FEEDING PRACTICES AND PSYCHOPATHOLOGY IN A NON-CLINICAL SAMPLE OF MOTHERS AND FATHERS

OBJECTIVE: To explore the relationships between controlling feeding practices and a range of mental health symptoms while considering both parent and child gender. METHOD: Mothers and fathers (N=214) of children aged 18-59 months completed selfreport measures of child feeding practices, eating psychopathology and general mental health symptomology. RESULTS: Feeding practices did not differ across any of the four parentchild gender dyads. Mothers‟ eating psychopathology scores were significantly higher than fathers‟ but parents did not significantly differ in the severity of their other mental health symptoms. Associations between disordered eating symptoms and controlling feeding practices were only seen in mothers of daughters and fathers of sons. In general, a range of mental health symptomologies in this non-clinical sample were related to more controlling feeding practices across all four dyads. Psychopathology was most strongly related to controlling feeding practices in parents of girls. CONCLUSION: Symptoms of psychopathology may be more likely to associate with controlling feeding practices in parents of daughters due to societal values for slimness in females.
International Schumpeterian Competition and Optimal R&D Subsidies

This paper studies the welfare effects of international competition in the market for innovations, and analyzes how competition affects the costs and the benefits of cooperative and non-cooperative RD the overall effect of competition on domestic welfare depends on the relative strength of these two counteracting forces. When governments play a strategic subsidy game, increases in foreign competition trigger a defensive innovation policy mechanism that raises the optimal domestic R&D subsidy. Cooperation in subsidies leads both countries to set higher subsidies. Finally, while cooperation is beneficial for the global economy, there exists a threshold level of competition below which the home country experiences welfare losses under cooperation.
An Investigation into the Differentiation of Hepatic Hydatid and Simple Cysts via Diffusion-Weighted MRI

Background and objective: As opposed to simple hepatic cysts (SHC) that are benign, hydatid hepatic cysts are associated with serious complications such as bacterial infection, anaphylactic shock, and spread of new cysts. However, both simple and hydatid cysts are asymptomatic and diagnosed accidentally. The present study was carried out in order to investigate the capacity of diffusion-weighted magnetic resonance imaging (DW-MRI) in differentiating hepatic hydatid and simple cysts among patients who referred to Azadi Teaching Hospital in Duhok, the Kurdistan Region of Iraq from October 2017 to April 2018. Materials and methods: Performing DW-MRI on 60 patients led to diagnosis of 108 cysts (16 completely liquid (CL) hydatid cysts, 14 cystic echinococcosis CE1, 10 CE2, 17 CE3, 15 CE4, and 36 simple hepatic cysts), and apparent diffusion coefficients (ADCs) were measured. A comparison between the signal intensity on the cysts and the liver was carried out by employing a 3-point scale (0=hypointense, 1= isointense, & 2=hyperintense). The results of the diagnosis were supported by surgery and/or ELISA test. Mean and standard deviation of different types of cysts using DW-MRI (b=0, 400, and 800) were calculated using SPSS 22.0, and the results were presented in tables and diagrams. Results: According to the results of DW-MRI (b=0, 400, and 800), most of the cysts were hyperintense. Moreover, the results of comparing mean DW cyst at b0, b400, and b800 among types of hepatic cysts showed that CE2 and CE4 had the highest prevalence. Also, comparing mean DW cyst to parenchyma ratio at b0, b400, and b800 among types of hepatic cysts revealed that the highest prevalence belonged to CE3 and CE4. Moreover, comparison of mean ADC cyst at b0 and b800 among types of hepatic cysts showed the highest prevalence for CE3 and CL. Finally, comparing mean ADC cyst to parenchyma ratio at b0 and b800 among types of hepatic cysts revealed the highest prevalence for CL and SHC. Conclusion: According to the results of the present study, it can be stated that DW-MRI may have the capacity to differentiate between hepatic hydatid and simple cysts.
APP Identification of APP : Gene and Protein Structure

Alzheimer’s dementia (AD) is the most common degenerative disorder of the central nervous system. Although the onset of dementia is above 65 years of age in the majority of the patients (late-onset AD, LOAD), a small subgroup of patients develops AD before 65 years of age (early-onset AD, EOAD). To date 3 genes responsible for EOAD have been identified: the amyloid precursor protein gene (APP), presenilin 1 (PSEN1) and presenilin 2 (PSEN2). PSEN1 is the most frequently mutated EOAD gene with a mutation frequency of 18 to 50% in autosomal dominant EOAD. In addition, the ε4 allele of the gene encoding apolipoprotein E (APOE) was identified as a risk factor for both LOAD and EOAD. Many studies reported other susceptibility genes, but the APOE 4 alelle has been the only risk factor that was consistently replicated in all AD populations. Extensive cell biology research in the past ten years led to the hypothesis that the 4 EOAD genes lead to AD through a common biological pathway resulting in abnormal APP processing by subtle different mechanisms. Now, transgenic mice are produced to study the influence of EOAD mutations in vivo, eventually leading to the development of novel therapeutic strategies.
Contextual and School Factors Associated with Achievement on a High-Stakes Examination.

This study identified student and school ‐ level factors associated with student achievement on the Ontario Secondary School Literacy Test (OSSLT), an examination that includes a student questionnaire examining home literacy practices. Linked student and school contextual data enabled the use of hierarchical linear modeling to complete the analyses and examine both student and school level effects. Fourteen student and three school level variables were found to be associated with students’ reading achievement and twelve student and two school level variables were associated with writing. Significant variations between schools were also found for students with individualized education plans, English as a second language, or previous eligibility on the OSSLT. Key words: hierarchical linear modeling, literacy testing, achievement, education factors Dans cette etude, les auteurs ont identifie les facteurs eleves et niveaux scolaires associes au rendement scolaire dans le Test de competences linguistiques de l’Ontario, un examen qui comprend un questionnaire pour les eleves au sujet des habitudes en matiere de litteratie a la maison.

Folate state of premature infants.

The recent widespread application of the microbiological assay of folate in serum, whole blood, and red cells has led to many reports on the folate status of infants (Matoth et al., 1964a, b; Matoth, Pinkas, and Sroka, 1965; Vanier and Tyas, 1966), including some on the folate status of premature infants (Shojania and Gross 1964; Strelling et al., 1966; Vanier and Tyas, 1967). This study was designed to investigate the serum and red cell folate levels in premature infants from birth to 6 months. The changes in folate levels of these premature infants were related to the folate status of the mothers, to the incidence of anaemia in the infants, and to the infants' dietary folate.
Possibility of Undifferentiated Human Thigh Adipose Stem Cells Differentiating into Functional Hepatocytes

Background This study aimed to investigate the possibility of isolating mesenchymal stem cells (MSCs) from human thigh adipose tissue and the ability of human thigh adipose stem cells (HTASCs) to differentiate into hepatocytes. Methods The adipose-derived stem cells (ADSCs) were isolated from thigh adipose tissue. Growth factors, cytokines, and hormones were added to the collagen coated dishes to induce the undifferentiated HTASCs to differentiate into hepatocyte-like cells. To confirm the experimental results, the expression of hepatocyte-specific markers on undifferentiated and differentiated HTASCs was analyzed using reverse transcription polymerase chain reaction and immunocytochemical staining. Differentiation efficiency was evaluated using functional tests such as periodic acid schiff (PAS) staining and detection of the albumin secretion level using enzyme-linked immunosorbent assay (ELISA). Results The majority of the undifferentiated HTASCs were changed into a more polygonal shape showing tight interactions between the cells. The differentiated HTASCs up-regulated mRNA of hepatocyte markers. Immunocytochemical analysis showed that they were intensely stained with anti-albumin antibody compared with undifferentiated HTASCs. PAS staining showed that HTASCs submitted to the hepatocyte differentiation protocol were able to more specifically store glycogen than undifferentiated HTASCs, displaying a purple color in the cytoplasm of the differentiated HTASCs. ELISA analyses showed that differentiated HTASCs could secrete albumin, which is one of the hepatocyte markers. Conclusions MSCs were islolated from human thigh adipose tissue differentiate to heapatocytes. The source of ADSCs is not only abundant abdominal adipose tissue, but also thigh adipose tissue for cell therapy in liver regeneration and tissue regeneration.
Consistent climate policies

What are the optimal climate policies when time preferences deviate from the standard exponential discounting and decision makers cannot commit to future policies? We show that, with time-declining discounting, the delay and persistence of climate impacts provide a commitment device to policy makers. We quantify the commitment value in a climate-economy model by solving time-consistent Markov equilibrium capital and emission taxes explicitly. The returns on capital and climate investments are no longer equal, leading to a large increase in the emission tax, compared to a benchmark with equalized returns. The commitment value increases the tax by a factor of 20 in our quantitative assessment.
SINGULAR INTEGRALS : THE ROLES OF CALDERON AND ZYGMUND

1130 NOTICES OF THE AMS VOLUME 45, NUMBER 9 T he subject matter of this essay is Alberto Calderón’s pivotal role in the creation of the modern theory of singular integrals. In that great enterprise Calderón had the good fortune of working with Antoni Zygmund, who was at first his teacher and mentor and later his collaborator. For that reason any account of that theory has to be in part the story of the efforts of both Zygmund and Calderón. With this in mind, I shall explain the various goals that motivated them, describe some of their shared accomplishments and later work of Calderón, and discuss briefly the wide influence of their achievements.
