Chiral Models in Noncommutative N=1/2 Four Dimensional Superspace

We derive the component Lagrangian for a generic N=1/2 supersymmetric chiral model with an arbitrary number of fields in four space-time dimensions. We then investigate a toy model in which the deformation parameter modifies the undeformed potential near the origin of the field space in a way which suggests possible physical applications.
Geographical Variations in the Interaction of Relative Age Effects in Youth and Adult Elite Soccer

Selection biases based on the use of cut-off dates and the timing of athletes’ birthdates have been termed relative age effects. These effects have been shown to differentially affect individuals involved in sport. For example, young male soccer players born early in their age group are overrepresented in elite teams while studies in adult soccer indicated potential carry-over effects from talent development systems. This two-study approach focuses on the processes within multi-year age groups in youth and adult elite soccer and on the role of players’ age position within the age band with regard to players’ birth year and birth month. Study 1 tests for an interaction of two different types of relative age effects among data from participants in the last five Under-17 FIFA World Cups (2007–2015). Analyses revealed a significant global within-year effect and varying birthdate distributions were found between confederations. Even stronger effects were found for constituent year effects. For the total sample, a multi-way frequency analysis (MFA) revealed an interaction with a pattern of a stronger within-year effect for the younger year group. This study highlights the need to consider interactions between different types of age effects. The main aim of Study 2 was to test for carry-over effects from previously found constituent year effects among players participating in the 2014 soccer World Cup and, therefore, to test for long-term effects of age grouping structures used during earlier stages of talent development. A secondary purpose of this study was to replicate findings on the existence of within-year effects and to test whether effects vary between continental confederations. No significant interaction between constituent year and within-year effects was shown by the MFA among the World Cup sample and previous findings on varying within-year effects were replicated. Results indicate that long-term effects of age grouping structures in earlier high-level talent development structures exist.

Symmetry properties in polarimetric remote sensing

This paper presents the relations among polarimetric backscattering coefficients from the viewpoint of symmetry groups. Symmetry of geophysical media encountered in remote sensing due to reflection, rotation, azimuthal, and centrical symmetry groups is considered for both reciprocal and nonreciprocal cases. On the basis of the invariance under symmetry transformations in the linear polarization basis, the scattering coefficients are related by a set of equations which restrict the number of independent parameters in the polarimetric covariance matrix. The properties derived under these transformations are general and apply to all scattering mechanisms in a given symmetrical configuration. The scattering coefficients calculated from theoretical models for layer random media and rough surfaces are shown to obey the derived symmetry relations. Use of symmetry properties in remote sensing of structural and environmental responses of scattering media is discussed. As a practical application, the results from this paper provide new methods for the external calibration of polarimetric radars without the deployment of man-made calibration targets.
Hybrid excited flux-switching permanent magnet machines

Hybrid excited machines are of interest due to the potential of combining the high power density of PM machines with the flux-adjusting capability of wound field excitation. This paper reviews currently documented hybrid excited machines and compares the flux control performance and torque density of alternative hybrid flux-switching PM machines by means of finite element analysis. The iron loss of the most promising design is calculated and shown to be much reduced from a conventional FSPM machine and it is shown that at high speed the iron losses can be reduced further by applying negative current to the field coil.
Condom Carnival: feasibility of a novel group intervention for decreasing sexual risk

Abstract Young people who engage in unprotected sex are at risk of negative consequences. The current study explored pre-post assessment data from 124, mostly Black, young people (M age = 19.6, SD = 2.8) attending an educational and vocational training programme who participated in the Condom Carnival, a novel, brief, interactive, peer-led, culturally tailored, sexual risk reduction group intervention. Condom Carnival activities provided practice negotiating condom use and using condoms correctly, instruction on safe lubricant use, and opportunities to dispel myths regarding condom size and breakage. We examined the preliminary impact of the Condom Carnival in increasing participants’ condom-related self-efficacy, lubricant safety awareness, and condom-related behavioural intentions and behaviour likelihood. Despite previous exposure to prevention efforts, participants reported significant increases in lubricant safety awareness (p < 0.001) and intentions to carry a condom in the next year (Z = −2.05, p = 0.04). Although participants reported high condom-related self-efficacy and intentions to use a condom, only three-quarters of young people endorsed intentions to always carry a condom. Findings indicate the need to explore the gap between intentions to use and carry condoms and to develop effective strategies to increase condom carrying among young people. Further assessment of the Condom Carnival as an add-on intervention to enhance sexual risk reduction efforts among youth is warranted.
A transient disruption of fibroblastic transcriptional regulatory network facilitates trans-differentiation

Transcriptional Regulatory Networks (TRNs) coordinate multiple transcription factors (TFs) in concert to maintain tissue homeostasis and cellular function. The re-establishment of target cell TRNs has been previously implicated in direct trans-differentiation studies where the newly introduced TFs switch on a set of key regulatory factors to induce de novo expression and function. However, the extent to which TRNs in starting cell types, such as dermal fibroblasts, protect cells from undergoing cellular reprogramming remains largely unexplored. In order to identify TFs specific to maintaining the fibroblast state, we performed systematic knockdown of 18 fibroblast-enriched TFs and analyzed differential mRNA expression against the same 18 genes, building a Matrix-RNAi. The resulting expression matrix revealed seven highly interconnected TFs. Interestingly, suppressing four out of seven TFs generated lipid droplets and induced PPARG and CEBPA expression in the presence of adipocyte-inducing medium only, while negative control knockdown cells maintained fibroblastic character in the same induction regime. Global gene expression analyses further revealed that the knockdown-induced adipocytes expressed genes associated with lipid metabolism and significantly suppressed fibroblast genes. Overall, this study reveals the critical role of the TRN in protecting cells against aberrant reprogramming, and demonstrates the vulnerability of donor cell's TRNs, offering a novel strategy to induce transgene-free trans-differentiations.
Predictability of Yen Angle & Appraisal of Various Cephalometric Parameters in the Assessment of Sagittal Relationship between Maxilla and Mandible in Angle ’ s Class II Malocclusion

The study was aimed to check the predictability and variability of Yen angle along with other sagittal discrepancy parameters and to discuss the correlation existing between them, so as to obtained a more reliable and least variable parameter for antero-posterior cephalometric analysis. The lateral cephalograms of 120 Class II malocclusion in Indian subjects were obtained and traced for seventeen different sagittal discrepancy parameters. The age of subjects ranged from 17-24 years. Study revealed that, Yen angle was highly reliable (CV= 1.81) and most homogenously distributed angular parameter to assess antero-posterior sagittal discrepancy. Other parameters like FABA, APDI/ PABA, SGn-AB and Beta angle also exhibit homogenous distribution and less variability in comparison to other parameters. As all the parameters used in the study share statistically significant correlation amongst themselves, instead of relying on one single parameter, others also should be checked and should be correlated with clinical findings.
Continuum and spectral line observations of the OH Megamaser galaxy Arp 220

We present MERLIN observations of the continuum (both 1.6 and 5 GHz) and OH maser emission towards Arp 220. The correct spatial configuration of the various components of the galaxy is revealed. In the eastern component the masers are shown to be generally coincident with the larger-scale continuum emission; in the west, the masers and continuum do not generally arise from the same location. A velocity gradient [(0.32 +- 0.03) km s-1 pc-1] is found in the eastern nuclear region on MERLIN scales; this gradient is three times smaller than that seen in H I and implies that the OH gas lies inside the H I. A re-anal. of previously presented global very long baseline interferometry data reveals a very high velocity gradient [(18.67 +- 0.12) km s-1 pc-1] in one component, possibly the site of a heavily obscured active galactic nucleus.

A pilot study of attachment style and emotional experience in adolescent girls with loss of control eating

ABSTRACT The established link between attachment insecurity and disinhibited eating may in part be explained by social problems, negative mood, and/or physiologic ‘stress’; however, these mechanisms have not been tested in adolescents with loss of control (LOC) eating. We therefore examined associations among attachment styles, social problems, negative emotions, and autonomic indices in 32 adolescent girls with recurrent LOC eating (body mass index z-score = 2.2 ± 0.4; age = 14.9 ± 1.6 years). Participants completed the Behavioral Systems Questionnaire to assess relational styles (secure, preoccupied, avoidant) and the Beck Depression Inventory to assess depressive symptoms. Parents completed the Child Behavior Checklist to assess teen social problems. Ecological momentary assessment (EMA) of real-world negative affect and social problems was collected for two weeks, and ambulatory monitoring of autonomic indices for two days. Preoccupied attachment was positively associated with depressive symptoms (n = 32, p = .03), greater EMA negative affect (n = 29, p = .03), and marginally higher EMA social problems (p = .06). Further, avoidant attachment was positively associated with ambulatory heart rate (n = 18, p < .05), but was not associated with any self-report indices. Adolescent girls with preoccupied versus dismissing attachment may exhibit different patterns of social problems, negative mood, and physiologic ‘stress’, suggesting the need for more detailed investigations of the mechanisms responsible for the relationship between insecure attachment and LOC eating.
Identifying the Overlap between Election Result and Candidates’ Ranking Based on Hashtag-Enhanced, Lexicon-Based Sentiment Analysis

The popularity and availability of Twitter as a service and a data source have fueled the interest in sentiment analysis. Previous research has shed light on the challenges that contextualizing effects and linguistic complexities pose for the accurate sentiment classification of tweets. We test the effect of adding manually-annotated, corpus-based hashtags to a sentiment lexicon, finding that this step in combination with negation detection increases prediction accuracy by about 7%. We then use our enhanced model to identify and rank the candidates of the Republican and Democratic Party of the 2016 New York primary election by the decreasing ratio of tweets that mentioned these individuals and had positive valence, and compare our results to the election outcome.
A Mouse Model of Metabolic Syndrome: Insulin Resistance, Fatty Liver and Non-Alcoholic Fatty Pancreas Disease (NAFPD) in C57BL/6 Mice Fed a High Fat Diet

Diet-induced obesity in C57BL/6 mice triggers common features of human metabolic syndrome (MetS). The purpose is to assess the suitability of a diet-induced obesity model for investigating non-alcoholic fatty pancreatic disease (NAFPD), fatty liver and insulin resistance. Adult C57BL/6 mice were fed either high-fat chow (HFC, 60% fat) or standard chow (SC, 10% fat) during a 16-week period. We evaluated in both groups: hepatopancreatic injuries, pancreatic islets size, alpha and beta-cell immunodensities, intraperitoneal insulin tolerance test (IPITT) and oral glucose tolerance test (OGTT). The HFC mice displayed greater mass gain (p<0.0001) and total visceral fat pads (p<0.001). OGTT showed impairment of glucose clearance in HFC mice (p<0.0001). IPITT revealed insulin resistance in HFC mice (p<0.0001). The HFC mice showed larger pancreatic islet size and significantly greater alpha and beta-cell immunodensities than SC mice. Pancreas and liver from HFC were heavier and contained higher fat concentration. In conclusion, C57BL/6 mice fed a high-fat diet develop features of NAFPD. Insulin resistance and ectopic accumulation of hepatic fat are well known to occur in MetS. Additionally, the importance of fat accumulation in the pancreas has been recently highlighted. Therefore, this model could help to elucidate target organ alterations associated with metabolic syndrome.
Objective Functions of Online Weight Noise Injection Training Algorithms for MLPs

Injecting weight noise during training has been a simple strategy to improve the fault tolerance of multilayer perceptrons (MLPs) for almost two decades, and several online training algorithms have been proposed in this regard. However, there are some misconceptions about the objective functions being minimized by these algorithms. Some existing results misinterpret that the prediction error of a trained MLP affected by weight noise is equivalent to the objective function of a weight noise injection algorithm. In this brief, we would like to clarify these misconceptions. Two weight noise injection scenarios will be considered: one is based on additive weight noise injection and the other is based on multiplicative weight noise injection. To avoid the misconceptions, we use their mean updating equations to analyze the objective functions. For injecting additive weight noise during training, we show that the true objective function is identical to the prediction error of a faulty MLP whose weights are affected by additive weight noise. It consists of the conventional mean square error and a smoothing regularizer. For injecting multiplicative weight noise during training, we show that the objective function is different from the prediction error of a faulty MLP whose weights are affected by multiplicative weight noise. With our results, some existing misconceptions regarding MLP training with weight noise injection can now be resolved.

Expression: A dyadic conversation aid using Google Glass for people who are blind or visually impaired

This paper presents `Expression' - an integrated assistive solution using Google Glass. The key function of the system is to enable the user in perceiving social signals during a natural dyadic conversation. The design and implementation of the system addressed a number of technical and research challenges - video acquisition and communication over Wi-Fi, efficient detection and tracking of faces, overheating of Google Glass, robust detection of facial features and modeling behavioral expressions, and feedback system for perceiving social signals. Performance evaluation was conducted to ensure the completeness and generalizability of models. Furthermore, usability studies were performed with ten (10) subjects (six visually impaired and four blind-folded) to illustrate the utility of the `Expression'. Subjective evaluation of Expression was performed using a five (5) point Likert Scale and was found to be excellent (4.383).
Maximum Eigenvalue Detection: Theory and Application

Channel sensing, i.e., detecting the presence of primary users, is a fundamental problem in cognitive radio. Energy detection is optimal for detecting independent and identically distributed (iid) signals, but not optimal for detecting correlated signals. In this paper, a method is proposed based on the sample covariance matrix calculated from a limited number of received signal samples. The maximum eigenvalue of the sample covariance matrix is used as the test statistic. Since the covariance matrix catches the correlations among the signal samples, the proposed method is better than the energy detection for correlated signals. For iid signals, the method approaches to the energy detection. The random matrix theory is used to analyze the method and set the threshold. Similar to energy detection, the methods do not need any information of the source signal and the channel as a priori. Also, no synchronization is needed. Simulations based on wireless microphone signals and iid signals are presented to verify the method.
Relation of Trihalomethane Concentrations in Public Water Supplies to Stillbirth and Birth Weight in Three Water Regions in England

We investigated the association between total trihalomethanes (TTHMs) and risk of stillbirth and low and very low birth weight in three water regions in England, 1992–1998; associations with individual trihalomethanes (THMs) were also examined. Modeled estimates of quarterly TTHM concentrations in water zones, categorized as low (< 30 μg/L), medium (30–59 μg/L), or high (≥60 μg/L), were linked to approximately 1 million routine birth and stillbirth records using maternal residence at time of birth. In one region, where there was a positive socioeconomic deprivation gradient across exposure categories, there was also a positive, significant association of TTHM with risk of stillbirth and low and very low birth weight. Overall summary estimates across the three regions using a random-effects model to allow for between-region heterogeneity in exposure effects showed small excess risks in areas with high TTHM concentrations for stillbirths [odds ratio (OR) = 1.11; 95% confidence interval (CI), 1.00–1.23), low birth weight (OR = 1.09; 95% CI, 0.93–1.27), and very low birth weight (OR = 1.05; 95% CI, 0.82–1.34). Among the individual THMs, chloroform showed a similar pattern of risk as TTHM, but no association was found with concentrations of bromodichloromethane or total brominated THMs. Our findings overall suggest a significant association of stillbirths with maternal residence in areas with high TTHM exposure. Further work is needed looking at cause-specific stillbirths and effects of other disinfection by-products and to help differentiate between alternative (noncausal) explanations and those that may derive from the water supply.
An experimental model to study the effects of a senna extract on the blood constituent labeling and biodistribution of a radiopharmaceutical in rats

ABSTRACT Cassia angustifolia Vahl (senna) is a natural product that contains sennosides, which are active components that affect the intestinal tract and induce diarrhea. Authors have shown that senna produces DNA (deoxyribonucleic acid) lesions in Escherichia coli cultures and can act as an antifungal agent. Natural drugs can alter the labeling of blood constituents with technetium-99m (99mTc) and can affect the biodistribution of radiopharmaceuticals. In this work, we have evaluated the influence of a senna extract on the radiolabeling of blood constituents and on the biodistribution of the radiopharmaceutical sodium pertechnetate (Na99mTcO4) in Wistar rats. Twelve animals were treated with senna extract for 7 days. Blood samples were withdrawn from the animals and the radiolabeling procedure was carried out. The senna extract did not modify the radiolabeling of the blood constituents. A biodistributional assay was performed by administering Na99mTcO4 and determining its activity in different organs and in blood. The senna extract altered the biodistribution of Na99mTcO4 in the thyroid, liver, pancreas, lungs and blood. These results are associated with properties of the chemical substances present in the aqueous senna extract. Although these assays were performed in animals, our findings suggest that caution should be exercised when nuclear medicine examinations using Na99mTcO4 are conducted in patients who are using senna extract.
