Microstrip Lines

Absfracf—Although graphical results and formulas are available for the design of microstrip couplers, the design procedure is hampered because evenand odd-mode impedances are always expressed in terms of the physical geometry. In practice the designer obtains these impedances and then requires to know the geometry given by them. A new design procedure for coupled parallel microstrip lines is therefore presented. The technique enables the geometry of the coupled lines to be obtained directly from the required evenand odd-mode impedances and uses single microstrip-line geometry as an intermediate step. The results are presented in graphical form using only two universal families of curves. Results are also presented in the form of simple formulas for design programs and also comparisons with practical results are made.
Reasoning With Neural Tensor Networks for Knowledge Base Completion

Knowledge bases are an important resource for question answering and other tasks but often suffer from incompleteness and lack of ability to reason over their discrete entities and relationships. In this paper we introduce an expressive neural tensor network suitable for reasoning over relationships between two entities. Previous work represented entities as either discrete atomic units or with a single entity vector representation. We show that performance can be improved when entities are represented as an average of their constituting word vectors. This allows sharing of statistical strength between, for instance, facts involving the "Sumatran tiger" and "Bengal tiger. " Lastly, we demonstrate that all models improve when these word vectors are initialized with vectors learned from unsupervised large corpora. We assess the model by considering the problem of predicting additional true relations between entities given a subset of the knowledge base. Our model outperforms previous models and can classify unseen relationships in WordNet and FreeBase with an accuracy of 86.2% and 90.0%, respectively.
Probabilistic collocation method for flow in porous media: Comparisons with other stochastic methods

An efficient method for uncertainty analysis of flow in random porous media is explored in this study, on the basis of combination of Karhunen‐Loeve expansion and probabilistic collocation method (PCM). The random log transformed hydraulic conductivity field is represented by the Karhunen‐Loeve expansion and the hydraulic head is expressed by the polynomial chaos expansion. Probabilistic collocation method is used to determine the coefficients of the polynomial chaos expansion by solving for the hydraulic head fields for different sets of collocation points. The procedure is straightforward and analogous to the Monte Carlo method, but the number of simulations required in PCM is significantly reduced. Steady state flows in saturated random porous media are simulated with the probabilistic collocation method, and comparisons are made with other stochastic methods: Monte Carlo method, the traditional polynomial chaos expansion (PCE) approach based on Galerkin scheme, and the moment‐equation approach based on Karhunen‐Loeve expansion (KLME). This study reveals that PCM and KLME are more efficient than the Galerkin PCE approach. While the computational efforts are greatly reduced compared to the direct sampling Monte Carlo method, the PCM and KLME approaches are able to accurately estimate the statistical moments and probability density function of the hydraulic head.
The Role of Sensitization to Allergen in Asthma Prediction and Prevention

The burden of asthma in childhood is considerable worldwide, although some populations are much more affected than others. Many attempts have been made by different investigators to identify the factors that could predict asthma development or persistence in childhood. In this review, the relation between atopic sensitization as an indicator of allergy and asthma in childhood will be discussed. Cross sectional studies, carried out in different countries, failed to show any firm correlation between asthma and atopic sensitization. Birth cohort mainly of infants at high risk for asthma and case–control studies showed that atopic sensitization was a risk factor for current asthma in children older than 6 years. In general, clear relations are observed mostly in affluent Western countries, whereas in less affluent countries, the picture is more heterogeneous. For the prediction of asthma development or persistence in school age children, other prerequisites should also be fulfilled such as family history of asthma and wheezing episodes at preschool age. Despite the conductance of different studies regarding the potential role of allergen avoidance for the primary prevention of childhood asthma, it does not seem that this approach is of benefit for primary prevention purposes. However, the identification of children at risk for asthma is of benefit as these subjects could be provided with the best management practices and with the appropriate secondary prevention measures.
Numerical Modeling of Triboelectric Charging of Granular Materials in Vibrated Beds

The triboelectric charging of granular materials is a complex physical phenomenon, the outcome of which is difficult to predict. The aim of this paper is to validate a numerical model of the tribocharging process taking place in vertically-vibrated beds of granular plastics. The granular dynamics is modeled with the Distinct Element Method that is commonly employed to design pneumatic conveyors or predict hopper emptying. The charge exchanged in granule-to-granule and granule-to-wall collisions is computed by taking into account the physical properties of the respective materials, their area of contact, as well as the effect of the electric field created by a system of high-voltage electrodes and by the charges of the granules themselves. The numerical model simulates also the free-fall motion of the charged granules in the electrostatic field created between two vertical plate electrodes. The outcome of the simulation, i.e. the charge of the particles collected at the two electrodes in a definite laps of time, is in good agreement with the results of an experiment carried out with mixtures of mm-size polyamide and polycarbonate granules in a laboratory vibrated bed.
Matrix-Mediated Biomineralization in Marine Mollusks: A Combined Transmission Electron Microscopy and Focused Ion Beam Approach

Abstract The teeth of the marine mollusk Acanthopleura hirtosa are an excellent example of a complex, organic, matrix-mediated biomineral, with the fully mineralized teeth comprising layers of iron oxide and iron oxyhydroxide minerals around a calcium apatite core. To investigate the relationship between the various mineral layers and the organic matrix fibers on which they grew, sections have been prepared from specific features in the teeth at controlled orientations using focused ion beam processing. Compositional and microstructural details of heterophase interfaces, and the fate of the organic matrix fibers within the mineral layers, can then be analyzed by a range of transmission electron microscopy (TEM) techniques. Energy-filtered TEM highlights the interlocking nature of the various mineral phases, while high-angle annular dark-field scanning TEM imaging demonstrates that the organic matrix continues to exist in the fully mineralized teeth. These new insights into the structure of this complex biomaterial are an important step in understanding the relationship between its structural and physical properties and may help explain its high strength and crack-resistance behavior.
The Effects of Endothelial Protein C Receptor Gene Polymorphisms on the Plasma sEPCR Level in Venous Thrombosis Patients

Objective: The aim of this study was to investigate variations in the endothelial cell protein C receptor gene (EPCRgene) that may play a role in thrombosis and the effects of these variations on the plasma soluble endothelial cell proteinC receptor (sEPCR) level in Turkish patients with venous thrombosis. Material and Methods: This study included 111 thrombosis patients and 73 healthy controls. Following DNAextraction, PCR, SSCP, and DNA sequencing analysis of 4 exons of the EPCR gene was performed. Plasma sEPCR wasmeasured via enzyme-linked immunosorbent assay (ELISA). Results: In all, 3 polymorphisms were detected in exons 1-4. C3998T (SNP no: rs2069952) polymorphism was detectedin intron 2 and C4678G (A1 haplotype) (SNP no: rs9574) in the 3’ untranslated region (3’UTR). There weren’t anysignificant differences in C3998T polymorphism between the control and patient groups. There wasn’t a significantdifference in plasma sEPCR levels between both controls and patients that carried the A1 allele. A4600G substitution (A3haplotype) (SNP no: rs867186) was observed in exon 4 and was associated with a 2.04-fold higher risk of thrombosis.A3 allele carriers had higher sEPCR levels than those without the allele. Mean sEPCR level in the patients with thehomozygous A3 allele was 289 ng μL–1, versus 113.42 ng μL–1 in those with the homozygous A1 allele. Conclusion: The A1 haplotype might offer protection against thrombosis and the A3 haplotype might be associatedboth with elevated plasma sEPCR and elevated risk of venous thrombosis in the Turkish population. Plasma sEPCRlevels were significantly higher in those that carried the A3 allele (4600A>G) (both patients and controls). Among theparticipants that carried the A1 allele (4678C>G), plasma sEPCR did not differ significantly.
The role of the serotonin system in ADHD

A limited number of studies have considered whether the activity of serotonin (5-HT) contributes to the problems experienced by youngsters with attention-deficit hyperactivity disorder (ADHD). The aim here is to review this work and propose interpretations. Peripheral measures of 5-HT and its metabolite do not point to a widespread association with the diagnosis. However, separate consideration of the major domains of dysfunction (motor activity, inattention and impulsivity) support a more differentiated assessment. The marked innervation of motor regions of the brain by 5-HT projections and the clear involvement of 5-HT systems in the control of locomotion in animals suggests a likely node for dysfunction in ADHD. The few relevant studies do not bear this out: but more attention should be accorded to the issue. The situation is different for attention-related processes. Here there are deficiencies in perceptual sensitivity and the appropriate designation of saliency to stimulation. These are attributable in part to altered 5-HT activity. Marked and opposite changes of 5-HT responsivity are associated with behavioral and cognitive impulsivity. There is also a growing series of studies demonstrating preferential transmission of various genetic markers for 5-HT receptors that are expressed in ADHD. Currently the heterogeneity of methods in this young discipline restricts the possibilities of definition of these markers and the types of ADHD in which they are expressed.
The locus of lexical preference effects in sentence comprehension

Abstract The retrieval and use of syntactic information associated with verbs during on-line comprehension was examined with reaction time (Experiment 1) and speed-accuracy tradeoff (Experiment 2) variants of a grammaticality judgment task. In three different syntactic environments, the preferred (most frequent) syntactic frame associated with a verb facilitated sentence processing relative to less-preferred (more infrequent) frames. Speed-accuracy tradeoff measures were used to explicitly examine whether the preferred frame associated with the verb has a higher probability of retrieval from the mental lexicon or whether it induces a serial parsing strategy. SAT analysis indicated that (i) in most contexts, less-preferred frames have a lower probability of retrieval, and (ii) verb preference does not induce a serial parsing strategy in the processing of lexically realized arguments, but may induce a serial assignment of possible filler-gap relations.
Acute alcohol intoxication and suicide among United States ethnic/racial groups: findings from the national violent death reporting system.

BACKGROUND To assess the prevalence and sociodemographic correlates of suicide involving acute alcohol intoxication among U.S. ethnic minorities. METHODS Data were derived from the restricted 2003 to 2009 National Violent Death Reporting System. The study focused on the sociodemographic and toxicological information of 59,384 male and female suicide decedents for 16 states of the United States. Acute alcohol intoxication was defined as having a blood alcohol content (BAC) ≥0.08 g/dl. Overall, 76% of decedents were tested for the presence of alcohol. RESULTS The proportion of suicide decedents with a positive BAC ranged from 47% among American Indians/Alaska Natives (AIs/ANs) to 23% among Asians/Pacific Islanders (PIs). Average BAC was highest among AIs/ANs. Among those who were tested for BAC, the proportion of decedents legally intoxicated prior to suicide was as follows: Blacks, 15%; AIs/ANs, 36%; Asians/PIs, 13%; and Hispanics, 28%. Bivariate associations showed that most suicide decedents who were legally intoxicated were male, younger than 30 years of age, with a high school education, not married, nonveterans, lived in metropolitan areas, and used a firearm to complete suicide. However, with the exception of Whites, most of these associations became not statistically significant in multivariate analysis. CONCLUSIONS Alcohol use and legal intoxication prior to completing suicide are common among U.S. ethnic groups, especially among men and those who are younger than 30 years of age. The AI/AN group had the highest mean BAC, the highest rate of legal intoxication and decedents who were particularly young. Suicide prevention strategies should address alcohol use as a risk factor. Alcohol problems prevention strategies should focus on suicide as a consequence of alcohol use, especially among AI/AN youth and young adults.
Temporal Graph Traversals: Definitions, Algorithms, and Applications

A temporal graph is a graph in which connections between vertices are active at specific times, and such temporal information leads to completely new patterns and knowledge that are not present in a non-temporal graph. In this paper, we study traversal problems in a temporal graph. Graph traversals, such as DFS and BFS, are basic operations for processing and studying a graph. While both DFS and BFS are well-known simple concepts, it is non-trivial to adopt the same notions from a non-temporal graph to a temporal graph. We analyze the difficulties of defining temporal graph traversals and propose new definitions of DFS and BFS for a temporal graph. We investigate the properties of temporal DFS and BFS, and propose efficient algorithms with optimal complexity. In particular, we also study important applications of temporal DFS and BFS. We verify the efficiency and importance of our graph traversal algorithms in real world temporal graphs.
Income Satisfaction and Deprivation in Spain

The first objective of our paper is to identify the determinants of income satisfaction in Spain, with one of these being relative deprivation, and the second is to measure this relative deprivation, in both monetary and satisfaction terms. To that end, we use data from the eight waves of the Spanish section of the European Community Household Panel (1994-2001). With respect to the first objective, we estimate models for categorical variables in order to test whether subjective satisfaction measures depend on relative deprivation, as well as on other determinants. As for the second objective, we first calculate inequality and polarization indices and then we specifically analyze whether the Spanish tax-benefit system helped to reduce individual deprivation. Our results suggest that the more unequal the income distribution is in a group, the less income satisfied is the individual. Moreover, being unemployed is one of the main determinants of deprivation, although public transfers help to reduce individual deprivation. When we observe the amount of public transfers received, deprivation is reduced up to a certain threshold, beyond which it continues to decline, but at a lower rate.
Cytokine-Mediated Regulation of Human B Cell Differentiation into Ig-Secreting Cells: Predominant Role of IL-21 Produced by CXCR5+ T Follicular Helper Cells1

Differentiation of B cells into Ig-secreting cells (ISC) is critical for the generation of protective humoral immune responses. Because of the important role played by secreted Ig in host protection against infection, it is necessary to identify molecules that control B cell differentiation. Recently, IL-21 was reported to generate ISC from activated human B cells. In this study, we examined the effects of IL-21 on the differentiation of all human mature B cell subsets—neonatal, transitional, naive, germinal center, IgM-memory, and isotype-switched memory cells—into ISC and compared its efficacy to that of IL-10, a well-known mediator of human B cell differentiation. IL-21 rapidly induced the generation of ISC and the secretion of vast quantities IgM, IgG and IgA from all of these B cell subsets. Its effect exceeded that of IL-10 by up to 100-fold, highlighting the potency of IL-21 as a B cell differentiation factor. Strikingly, IL-4 suppressed the stimulatory effects of IL-21 on naive B cells by reducing the expression of B-lymphocyte induced maturation protein-1 (Blimp-1). In contrast, memory B cells were resistant to the inhibitory effects of IL-4. Finally, the ability of human tonsillar CD4+CXCR5+CCR7− T follicular helper (TFH) cells, known to be a rich source of IL-21, to induce the differentiation of autologous B cells into ISC was mediated by the production of IL-21. These findings suggest that IL-21 produced by TFH cells during the primary as well as the subsequent responses to T cell-dependent Ag makes a major contribution to eliciting and maintaining long-lived humoral immunity.
Who's Posting Facebook Faux Pas? A Cross-Cultural Examination of Personality Differences

This study examines culture and personality differences in student reports of the likelihood that they would post various types of information on their Facebook profiles. As predicted those high on conscientiousness, agreeableness, and emotional stability proved significantly less likely to report posting problematic content (e.g., substance abuse, sexual content) on their profile. Those who scored high on Compulsive Internet Use indicated a greater likelihood to post such profile information. Consistent with our expectations, our cross-cultural analysis revealed that US students were more inclined than German students to post problematic information to their Facebook site. Implications of these results and recommendations for future research are discussed.
Assessment of oral status and oro-pharyngeal candidosis in elderly in short-term hospital care.

OBJECTIVES To evaluate prevalence of oral candidosis and predisposing conditions in hospitalized elderly patients. DESIGN We examined 104 elder patients recently hospitalized in two geriatric hospitals for shortterm hospital care. METHODS Information was collected on patients' sex, age, mental and physical disabilities, smoking habits, medical prescriptions, oral pathologies, denture wearing, oral hygiene habits and oral hygiene level. Quality of existing dentures was evaluated. Oral mucosae were examined for clinical signs suggesting oral candidosis. Semiquantitative cultures of Candida were carried out to confirm the clinical diagnosis. RESULTS The diagnosis of oral candidosis was confirmed in 18/54 patients showing clinical signs of oral candidosis. Confirmed oral candidosis was associated with the presence of other infections, proteo-caloric denutrition, ongoing antibiotic therapy, and denture wearing. Dentures in patients with confirmed oral candidosis at poorer technical quality of the acrylic surface in contact with the underlying mucosa. CONCLUSION The wearing of removable dentures is a major predisposing factor for oro-pharyngeal candidosis of elderly patients in short-term hospital care. Appropriate oral and denture hygiene measures as well as denture wearing habits should be introduced or maintained to prevent this infection.
A Connected E-Shape and U-Shape Dual-Band Patch Antenna for Different Wireless Applications

In this paper, dual operation E-shape and U-shape Patch Antenna feed by transmission line is presented and study the effect of antenna dimensions length (L), width (W) and substrate parameters relative dielectric constant(Er), substrate thickness on radiation parameters of Band width. The proposed antenna is designed on two-layer, one RT/Duroid 6006 laminate substrate and another ground plane with an area of 33 mm by 42 mm. This paper contains designing a Connected E-Shape and U-Shape Dual Band Patch Antenna for different wireless applications except for its narrow band width. The dual operation frequencies are 2.46 GHz and 4.9 GHz. A (-8 dB) bandwidths of return loss S characteristic for the dual band are 13.02 % and 3.28 % respectively. This connected U-shape & E-shape patch antenna is mainly applicable to wireless local area net-works (WLAN). This paper suggests an alternative approach in enhancing the band width of microstrip antenna for the wireless application operating at a dual frequencies 2.46 GHz and 4.9 GHz. The measured results have been compared with the simulated results using software GEMS version-7.0.
Transmission network analysis to complement routine tuberculosis contact investigations.

OBJECTIVE We examined the feasibility and value of network analysis to complement routine tuberculosis (TB) contact investigation procedures during an outbreak. METHODS We reviewed hospital, health department, and jail records and interviewed TB patients. Mycobacterium tuberculosis isolates were genotyped. We evaluated contacts of TB patients for latent TB infection (LTBI) and TB, and analyzed routine contact investigation data, including tuberculin skin test (TST) results. Outcomes included number of contacts identified, number of contacts evaluated, and their TST status. We used network analysis visualizations and metrics (reach, degree, betweenness) to characterize the outbreak. RESULTS secondary TB patients and more than 1200 contacts. Genotyping detected a 21-band pattern of a strain W variant. No HIV-infected patients were diagnosed. Contacts prioritized by network analysis were more likely to have LTBI than nonprioritized contacts (odds ratio=7.8; 95% confidence interval=1.6, 36.6). Network visualizations and metrics highlighted patients central to sustaining the outbreak and helped prioritize contacts for evaluation. CONCLUSIONS A network-informed approach to TB contact investigations provided a novel means to examine large quantities of data and helped focus TB control.
