Moving Virtual Array Measurement Scheme in High-Speed Railway

The moving virtual array measurement scheme, which means several adjacent samples from one single receiving antenna on a moving train or vehicle can be considered as the reception of multiple antennas, is proposed to overcome the difficulties of multiple-input-multiple-output (MIMO) channel measurement in high-speed railway scenario. This idea is similar to the virtual array measurement in static environment. Furthermore, the number of the equivalent elements in moving virtual array is derived by combining with the principle of switch multiplexed array scheme used in time-variant channel measurement. To verify this scheme, a 1X3 single-input-multiple-output (SIMO) channel sounder is built, and the measurements are carried out in a moving environment. The results show that moving virtual array scheme can reflect the spatial channel characteristics, especially in high signal-to-noise ratio (SNR) range. Finally, the applications of this scheme are discussed.
Predicting Decade-Long Changes in Community Motor Vehicle Theft Rates

Motor vehicle theft (MVT) is arguably the most underresearched Part I crime. This work predicts long-term changes in community MVT rates, extrapolating from earlier work in community fabric and changing personal crime and delinquency rates and cross-sectional work on MVT. Police data on MVTs generated MVT rates in one Midwestern city in 1990-1991 and 2000-2001 that were linked with census block group data. MVT rates went up later in communities more racially mixed initially and in those surrounded by initially higher MVT rates, suggesting extant community structure and surrounding crime generate subsequently unfolding impacts on MVT. A second series of models links changing MVT rates with contemporaneously increasing racial heterogeneity, decreasing community instability, and increasing surrounding MVT rates. Some associations between community structure and changing delinquency or crime appear relevant to shifting MVT rates. Resident-based, target-linked, and offender-dependent processes to be investigated are outlined.
Weight functions based on the convolutions of atomic functions

In the report new weight functions with low side-lobe level, based on convolutions of atomic functions are presented. There are effective algorithms for their computation. To increase coherent gain the window is truncated with an additional one. This approach allows us to obtain windows with good properties. The degree of cut of the function determines the relation between side-lobes and coherent gain. Usually the best windows are obtained with the cut near the effective support of function.
The Mood Assessment Program is now on the Australian map

Objective: To report on the wide uptake and utility of the freely available Mood Assessment Program (MAP) since its introduction as a tool to assist diagnosis and management of mood disorders. Method: By mid-2012, some 16,000 patients had completed the MAP. We analyse data derived from such a sample. Results: The majority of patients utilizing this service were referred by general practitioners, psychologists and psychiatrists from within New South Wales (NSW). The great majority across age bands found the MAP easy to complete and judged that it covers issues relating to their mood disorder very well or completely. Conclusion: The MAP is available for use Australia-wide with ready referral access for patients of mental health practitioners in general practice, psychiatry, psychology and social work. The online availability of the service makes it ideal for use in areas where access to health services is limited.
Design and Performance Aspects of an Adaptive Cylindrical Beamforming Array

In this article, the design of a cylindrical beamforming array (CBA) is presented. The array is conformed over a ring of a conducting circular cylinder. From the total number of elements, M, of the array, a subset of N successive elements is enabled each time. The selection of the subset is based on the minimization of the angle between its broadside direction and the direction of arrival (DOA) of the signal of interest (SOI). Furthermore, by adaptively combining the outputs of the active subarray, the gain of the system is maximized. The cylindrical beamforming array is integrated into the CDMA acquisition phase, where a joint process of code acquisition and smart-antenna adaptation is applied. The array is implemented for the uplink of a base-station receiver of a wireless communications system. A detailed justification and a performance evaluation under various simulation scenarios, which include integration into spatial and two-dimensional rake receivers, are also presented.
Fuzzy Temporal Constraints Based Fuzzy Clustering Algorithm for Temporal Dadaset

Fuzzy c-means plays an important role in investigating the structure of dataset. In order to clustering the temporal or spatial dataset, constraints-equipped version of fuzzy c-means was proposed in literature. This paper focuses on the clustering of temporal dataset, and presents a new version of constraints-equipped fuzzy c-means algorithm, where the temporal constraints are described by fuzzy sets rather than crisp intervals. This new version fuzzy c-means overcomes the disadvantages of the old version where strict requirements on the choosing of the parameters are needed and in many cases the result is not so satisfactory. The experiments carried in this paper illustrate the good performance of the new version of temporal constraints-equipped fuzzy c-means.

Patients With Evidence of Coronary Endothelial Dysfunction as Assessed by Acetylcholine Infusion Demonstrate Marked Increase in Sensitivit to Constrictor Effects of Catecholamines

Background Studies in patients undergoing cardiac catheterization have demonstrated that normal coronary arteries dilate and atherosclerotic arteries constrict in response to exercise and the cold pressor test, but the mechanisms are unknown. These vasomotor responses are mirrored by the vasomotor response to the endothelium-dependent agent acetylcholine. Exercise and the cold pressor test are associated with adrenergic stimulation and increased circulating catecholamines. The present study tested the hypothesis that coronary arteries with intact endothelial function are relatively resistant to the constrictor effects of catecholamines, whereas arteries with loss of endothelial function have increased sensitivity to catecholamine-induced constriction. Methods and Results The vasomotor function of the coronary endothelium was assessed by serial acetylcholine infusions (final concentration, 10−8 to 10−6 M) in 30 segments in 15 patients with minimal or no evidence of coronary atherosclerosis. The acetylcholine responses were related to the vasomotor response to intracoronary phenylephrine infusion (final concentration, 10−9 to 10−6 M) in the same segments. In the group of 18 segments that constricted to acetylcholine, there was a constrictor response to phenylephrine at an approximately 100-fold lower concentration than the group of 12 segments that did not constrict to acetylcholine. Conclusions These results suggest that the endothelial dysfunction that characterizes early and late atherosclerosis is associated with a marked increase in sensitivity to the constrictor effects of catecholamines. This finding may explain the constrictor responses of atherosclerotic coronary arteries to exercise and the cold pressor test. In stenotic coronary arteries this mechanism may play a role in the production of myocardial ischemia.
Leverage and Its Impact on Earnings and Share Price: A Special Reference to Listed Companies of Colombo Stock Exchange (CSE) in Sri Lanka

This study investigates the impact of leverage on earnings and share price of listed companies on Colombo Stock Exchange (CSE) in Sri Lanka. The study was identified 20 companies listed on the CSE for the period from year 2007/2008 to 2011/2012. The Degree of Operating Leverages (DOL), Degree of Financial Leverage (DFL) & Degree of Combined Leverage (DCL) are the independent variables and Earning Per Share (EPS) and Share Price (SP) are the dependent variables for this study. The present study used the correlation coefficient and linear regression to measure the variables. The findings revealed that only 4% earnings can be explained by DOL, DFL and DCL and there is no significant relationship with EPS. It is also found that 3% SP is attributed by DOL, DFL and DCL and there is no significant relationship with SP. Thus, fixed operating expenses and the financing mix decisions of the firm are not significantly impact the earning capacity of the listed companies in CSE.
Viral replication and paracrine effects result in distinct, functional responses of dendritic cells following infection with dengue 2 virus

Dengue virus (DENV), a re‐emerging arbovirus, readily infects dendritic cells (DC) in culture and in vivo. However, there have been contradictory reports regarding the effect of DENV infection on DC activation and maturation. DC undergo a series of functional changes following exposure to infectious agents, including cytokine production and costimulatory and MHC molecule induction, culminating in stimulation of adaptive immune responses. Immunological memory to primary DENV infection critically influences disease severity during subsequent infections with heterologous serotypes. To explore these phenomena, we examined DENV infection‐dependent and ‐independent effects on DC secretory, phenotypic, and allostimulatory functions. DENV infection of DC resulted in the secretion of a broad array of cytokines and chemokines. Type I IFN produced by DC inhibited propagation of infection and induced the chemokine IFN‐γ‐inducible protein 10 (IP‐10; CXCL10). Based on intracellular cytokine staining, infected DC produced less IP‐10 but more TNF‐α than uninfected bystander cells in the same culture. DENV exposure activated surface molecule expression on infected and bystander cells; infected DC had enhanced programmed death ligand 2 (PD‐L2) and MHC II expression but reduced levels of PD‐L1, CD80, CD86, and MHC I relative to bystander DC. Dengue‐infected DC cultures stimulated resting allogeneic CD4 T cell proliferation, although an increasing multiplicity of infection was associated with decreasing stimulatory capacity of DC. These data demonstrate that functional maturation of DC in response to dengue infection is modified by the presence of virus through IFN‐dependent and ‐independent mechanisms with consequences for the development of adaptive immunity.
Kinematics of the Ankle/Foot Complex: Plantarflexion and Dorsiflexion

In an in vivo investigation of eight healthy volunteers, three dimensional ankle/foot kinematics were analyzed by roentgen stereophotogrammetry in 10° steps of motion from 30° of plantar flexion to 30° of dorsiflexion of the foot. The study included all of the joints between the tibia and the first metatarsal, as well as the talocalcaneal joint, and was performed under full body load. Although the talocrural joint was found to account for most of the rotation around the transverse axis occurring from 30° of plantar flexion to 30° of dorsiflexion, there was a substantial contribution from the joints of the arch. This was seen particularly in the input arc from 30° of plantar flexion to the neutral position, where the dorsiflexion motion of these joints amounted to 10% to 41% of the total transverse axis rotation.
Preventing conduct problems and improving school readiness: evaluation of the Incredible Years Teacher and Child Training Programs in high-risk schools.

BACKGROUND School readiness, conceptualized as three components including emotional self-regulation, social competence, and family/school involvement, as well as absence of conduct problems play a key role in young children's future interpersonal adjustment and academic success. Unfortunately, exposure to multiple poverty-related risks increases the odds that children will demonstrate increased emotional dysregulation, fewer social skills, less teacher/parent involvement and more conduct problems. Consequently intervention offered to socio-economically disadvantaged populations that includes a social and emotional school curriculum and trains teachers in effective classroom management skills and in promotion of parent-school involvement would seem to be a strategic strategy for improving young children's school readiness, leading to later academic success and prevention of the development of conduct disorders. METHODS This randomized trial evaluated the Incredible Years (IY) Teacher Classroom Management and Child Social and Emotion curriculum (Dinosaur School) as a universal prevention program for children enrolled in Head Start, kindergarten, or first grade classrooms in schools selected because of high rates of poverty. Trained teachers offered the Dinosaur School curriculum to all their students in bi-weekly lessons throughout the year. They sent home weekly dinosaur homework to encourage parents' involvement. Part of the curriculum involved promotion of lesson objectives through the teachers' continual use of positive classroom management skills focused on building social competence and emotional self-regulation skills as well as decreasing conduct problems. Matched pairs of schools were randomly assigned to intervention or control conditions. RESULTS Results from multi-level models on a total of 153 teachers and 1,768 students are presented. Children and teachers were observed in the classrooms by blinded observers at the beginning and the end of the school year. Results indicated that intervention teachers used more positive classroom management strategies and their students showed more social competence and emotional self-regulation and fewer conduct problems than control teachers and students. Intervention teachers reported more involvement with parents than control teachers. Satisfaction with the program was very high regardless of grade levels. CONCLUSIONS These findings provide support for the efficacy of this universal preventive curriculum for enhancing school protective factors and reducing child and classroom risk factors faced by socio-economically disadvantaged children.

Compact 2.5 GHz circularly polarized antenna using high permittivity substrate

The compact circularly polarized antennas by employing high-permittivity and low loss substrates are investigated. The antennas were individually fabricated on nano-Al/sub 2/O/sub 3/ (/spl epsiv//sub r/ = 9.7, Q/spl times/f value of 500,000 GHz) and Al/sub 2/O/sub 3/ (/spl epsiv//sub r/ = 9.7, Q/spl times/f value of 200,000 GHz) substrates and operated at 2.5 GHz. The presented circularly polarized antennas using nano-Al/sub 2/O/sub 3/ and Al/sub 2/O/sub 3/ substrates can achieve 80 MHz and 60 MHz of 3-dB axial ratio bandwidth (CP bandwidth), respectively. The application of the nano-Al/sub 2/O/sub 3/ substrate demonstrates a wider CP bandwidth and a smaller size of the antenna.
Effect of stress on reproduction in farmed male mink ( Neovison vison )-behavioural and hormonal traits characterising male mink reproductive success

It is well known, that hormones released during a stressful event may impair the function of the reproductive axis, however these effects have received little attention in farmed male mink. The aim of the present study was therefore to explore the relationship between the reproductive success of farmed male mink and stress related measures. Altogether 303 male mink were examined for behaviour, faecal cortisol metabolite concentration (FCM), response in stick tests, fur-chewing and body condition during the pre-mating period from late January to the end of February. At the end of the mating season these males were evaluated for mating success, and the males with the highest (SU, n=47) and the lowest (NSU, n=44) mating success were furthermore examined post mating (19 th of March) for the above mentioned variables. In addition, faecal testosterone metabolite concentrations (FTM) were measured in this subset of males during the entire study period. The measured variables were compared between groups, and all males were evaluated for their reproductive success based on individual mating success, mean litter size, kit mortality and kit growth. No effect of FCM or FTM concentrations on any of the reproductive parameters was detected in this study, and neither were differences in these observed between groups. However, a surprisingly positive correlation between FCM and FTM was observed (P< 0.001), with both steroid concentrations decreasing from late January to mid March. Males exhibiting a higher level of pre-feeding abnormal behaviour had increased mating success (SU vs. NSU: P= 0.016; all males: P= 0.056), contradicting the hypothesis of stress impairing reproduction in male mink. Males that showed more aggressive behaviour had a higher mating success, sired larger litters and had lower kit mortality (all P< 0.03), suggesting a key role of aggressive behaviour in the determination of male mink reproductive success. No correlation between aggressive behaviour and FTM concentration was observed. Male mating success was furthermore characterised by SU-males having fewer barren females and being more active during the natural mating period. Males with a higher mating success sired larger litters (P= 0.027), while also experiencing a higher kit mortality (SU vs. NSU: P= 0.014). Moreover, there was a considerable variation in mating success and litter size between breeding lines (colour types) and body conditions scores. To obtain the highest reproduction, an intermediate and not high body condition around mating can be advised. In conclusion, under normal farm conditions, this study detected no negative influence of the variation in the stress related measures examined in the current study period. However, variation in behavioural characteristics, body condition and breeding line significantly affected farmed male mink reproductive success.
Angiotensin II and the vascular phenotype in hypertension

Hypertension is associated with vascular changes characterised by remodelling, endothelial dysfunction and hyperreactivity. Cellular processes underlying these perturbations include altered vascular smooth muscle cell growth and apoptosis, fibrosis, hypercontractility and calcification. Inflammation, associated with macrophage infiltration and increased expression of redox-sensitive pro-inflammatory genes, also contributes to vascular remodelling. Many of these features occur with ageing, and the vascular phenotype in hypertension is considered a phenomenon of ‘premature vascular ageing’. Among the many factors involved in the hypertensive vascular phenotype, angiotensin II (Ang II) is especially important. Ang II, previously thought to be the sole effector of the renin–angiotensin system (RAS), is converted to smaller peptides [Ang III, Ang IV, Ang-(1-7)] that are biologically active in the vascular system. Another new component of the RAS is the (pro)renin receptor, which signals through Ang-II-independent mechanisms and might influence vascular function. Ang II mediates effects through complex signalling pathways on binding to its G-protein-coupled receptors (GPCRs) AT1R and AT2R. These receptors are regulated by the GPCR-interacting proteins ATRAP, ARAP1 and ATIP. AT1R activation induces effects through the phospholipase C pathway, mitogen-activated protein kinases, tyrosine kinases/phosphatases, RhoA/Rhokinase and NAD(P)H-oxidase-derived reactive oxygen species. Here we focus on recent developments and new research trends related to Ang II and the RAS and involvement in the hypertensive vascular phenotype.
Epidemiology of Meningitis and Encephalitis in Infants and Children in the United States, 2011–2014

Background: Large epidemiologic studies evaluating the etiologies, management decisions and outcomes of infants and children with meningitis and encephalitis in the United States are lacking. Methods: Children 0–17 years of age with meningitis or encephalitis as assessed by International Classification of Diseases, Ninth Revision, codes available in the Premier Healthcare Database during 2011–2014 were analyzed. Results: Six thousand six hundred sixty-five patients with meningitis or encephalitis were identified; 3030 (45.5%) were younger than 1 year of age, 295 (4.4%) were 1–2 years of age, 1460 (21.9%) were 3–9 years of age, and 1880 (28.2%) were 10–17 years of age. Etiologies included enterovirus (58.4%), unknown (23.7%), bacterial (13.0%), noninfectious (3.1%), herpes simplex virus (1.5%), other viruses (0.7%), arboviruses (0.5%) and fungal (0.04%). The majority of patients were male [3847 (57.7%)] and healthy [6094 (91.4%)] with no reported underlying conditions. Most underwent a lumbar puncture in the emergency department [5363 (80%)] and were admitted to the hospital [5363 (83.1%)]. Antibiotic therapy was frequent (92.2%) with children younger than 1 year of age with the highest rates (97.7%). Antiviral therapy was less common (31.1%). Only 539 (8.1%) of 6665 of patients received steroids. Early administration of adjunctive steroids was not associated with a reduction in mortality (P = 0.266). The overall median length of stay was 2 days. Overall mortality rate (0.5%) and readmission rates (<1%) was low for both groups. Conclusion: Meningitis and encephalitis in infants and children in the United States are more commonly caused by viruses and are treated empirically with antibiotic therapy and antiviral therapy in a significant proportion of cases. Adjunctive steroids are used infrequently and are not associated with a benefit in mortality.
