Magnetic fields in barred galaxies

Aims. We present a model of the global magnetic field in the barred galaxy NGC 1365 based jointly on the large-scale velocity field of interstellar gas fitted to H i and CO observations of this galaxy and on mean-field dynamo theory. The aim of the paper is to present a detailed quantitative comparison of a galactic dynamo model with independent radio observations. Methods. We consider several gas dynamical models, based on two rotation curves. We test a range of nonlinear dynamo models that include plausible variations of those parameters that are poorly known from observations. Models for the cosmic ray distribution in the galaxy are introduced in order to produce synthetic radio polarization maps that allow direct comparison with those observed at λλ3. 5 and 6.2 cm. Results. We show that the dynamo model is robust in that the most important magnetic features are controlled by the relatively well established properties of the density distribution and gas velocity field. The optimal agreement between the synthetic polarization maps and observations is obtained when a uniform cosmic ray distribution is adopted. These maps are sensitive to the number density of thermal ionized gas because of Faraday depolarization effects. Our results are compatible with the observed polarized radio intensity and Faraday rotation measure if the degree of ionization is between 0.01 and 0.2 (with respect to the total gas density, rather than to the diffuse gas alone). We find some indirect evidence for enhanced turbulence in the regions of strong velocity shear (spiral arms and large-scale shocks in the bar) and within 1–2 kpc of the galactic centre. We confirm that magnetic stresses can drive an inflow of gas into the inner 1 kpc of the galaxy at a rate of a few M yr−1. Conclusions. The dynamo models are successful to some extent in modelling the large scale regular magnetic field in this galaxy. Our results demonstrate that dynamo models and synthetic polarization maps can provide information about both the gas dynamical models and conditions in the interstellar medium. In particular, it seems that large-scale deviations from energy equipartition (or pressure balance) between large-scale magnetic fields and cosmic rays are unavoidable. We demonstrate that the dynamical effects of magnetic fields cannot be everywhere ignored in galaxy modelling.
An FPGA based service Robot for floor cleaning with autonomous navigation

In this present era, people live a very busy life. People in megalopolis have irregular and long working times. In such a situation people find hard to save their time. Especially for working women and old age people required floor cleaning type service robots. Floor cleaning is a typical service robot application. The algorithm derived in this paper is used to design a fully autonomous Service Robot. It able to navigate by detecting obstacles and manipulates its direction with the help of inputs from ultrasonic sensors. The hardware efficient method are used to accomplish the task. The uniqueness of this algorithm apart from being autonomous is that various techniques are used for the purpose of smart obstacle avoidance.
Strong convergence theorems for maximal monotone operators and continuous pseudocontractive mappings

We introduce a new iterative algorithm for finding a common element of the solution set of the variational inequality problem for a continuous monotone mapping, the zero point set of a maximal monotone operator, and the fixed point set of a continuous pseudocontractive mapping in a Hilbert space. Then we establish strong convergence of the sequence generated by the proposed algorithm to a common point of three sets, which is a solution of a certain variational inequality. Further, we find the minimum-norm element in common set of three sets. As applications, we consider iterative algorithms for the equilibrium problem coupled with fixed point problem. ©2016 All rights reserved.
The role of genetic relatedness among social mates in a cooperative breeder

Breeding with relatives can have severe fitness consequences, so avoiding these costs is often evolutionarily favored. There are a number of mechanisms that reduce the likelihood of mating with relatives, including avoiding relatives as mates (through sex-biased dispersal and mate choice) and delayed sexual maturity in the presence of relatives. Here, we examine these mechanisms in Neolamprologus pulcher, a group-living cichlid fish that exhibits male-biased dispersal. Despite sex-biased dispersal in this species, mean relatedness between social mates was not different from that expected if pairs had formed randomly, suggesting individuals neither actively avoid nor prefer pairing with relatives. Furthermore, gonadal investment of subordinates living in social groups was not correlated with their relatedness to the opposite-sex dominant breeder in the group, suggesting that sexual maturation does not depend on the presence or absence of a relative. Highly related social pairs showed higher rates of within-pair aggression and lower rates of nonaggressive social affiliation than less-related social pairs. Breeder investment and indicators of female breeder and group quality were not correlated with relatedness values between social mates. However, scraping rates (a potential quality indicator) were lower in males paired with more closely related females. We consider whether the apparent lack of inbreeding avoidance reflects an evolutionary history of limited breeding opportunities in N. pulcher or a facultative strategy of more-fit individuals and discuss the behavioral results in light of the suggested nonassortative mating with regard to relatedness.

The dataset comes with associated relevance and diversity assessments performed by trusted annotators. The data consists of around 300 complex queries represented via 86,769 Flickr photos, around 27M photo links for around 6,000 users, metadata, Wikipedia pages and content descriptors for text and visual modalities, including state of the art deep features. To facilitate distribution, only Creative Commons content allowing redistribution was included in the dataset. The proposed dataset was validated during the 2015 Retrieving Diverse Social Images Task at the MediaEval Benchmarking.
Impact of ageing on depression and activities of daily livings in normal elderly subjects living in old age homes and communities of Kanpur, U.P.

Introduction: Ageing is a progressive, generalized impairment of functions resulting in loss of adaptive response to stress and increasing the risk of age related disease. Methodology: A sample of 200 elderly subjects i.e. 100 from the community (group A) and 100 from Old age home (group B) of sixty & above years of age were taken by the convenience sampling method. The subjects were collected through various old age homes and community which includes Vaikunth Dham Old Age Home, Ishwar Prem Ashram, Swaraj Ashram, Ramkrishna Mission old age home and nearby community located in the Kanpur and Varanasi. The subjects were assigned a number to maintain the confidentiality of the subjects and then the scales were used to assess the scores i.e., Geriatric Depression Scale (GDS) and Barthel index of daily livings were used to check the level of depression & ADL’s and then the scores were compared. The results: The mean GDS scores for group A were 11.32 and for group B were 16.42 with a value of -6.981 with a p value of 0.00* and mean ADL’s scores on the Barthel index for group A were16. 54 and 17.98 for group B within value of -2.898 with a p value of 0.004* which shows there is a significant difference. Conclusion: Elderly subjects living in Old age home are more affected in terms of depression and ADL’s as compared to community dwelling elder subjects as old people living in their own homes were most able to cope in their homes. They received more support from relatives and friends than from health and social services
Stereo CUTLASS - A new capability for the SuperDARN HF radars

Abstract. The Super Dual Auroral Radar Network (SuperDARN), which consists of networks of HF radars surrounding the northern and southern poles, has proven to be an extremely successful experimental technique in a wide range of scientific areas. The basic design of the radars, which contributes to SuperDARN, has remained virtually unchanged since the first radar was built in the early 1980s. This paper presents the first results of a significant new development of the basic system. Termed "Stereo", this development involves the addition of a duplicate receive channel and makes use of the spare duty cycle available in the current transmitters. The Stereo system has been implemented on the two radars that form the Co-operative UK Twin Located Auroral Sounding System (CUTLASS), which are the easternmost pair of radars in the Northern Hemisphere SuperDARN chain. Instead of the standard 7 pulse sequence normally employed by the radars, two such pulse sequences are interleaved and transmitted at different frequencies separated by more than 15kHz. This development allows for the radar to run two entirely different experimental modes simultaneously. Here we describe the basic Stereo system and some of the early results. We also identify potential new experiments which could be run with Stereo to complement the existing standard SuperDARN radar. Key words.

Reviewing Regulatory Focus Based on Four Regulatory Forms

This study employs the four regulatory forms (goal pursuit, goal maintenance, negative escape, and active avoidance) to illuminate the heterogeneousness among regulatory focus measurements and activations. The first two studies consistently found that promotion focus involves goal pursuit orientation; however, prevention focus encompasses a goal maintenance and a negative escape orientation. The regulatory forms were then applied to regulatory fit research to investigate how the matches of regulatory forms determine the effect sizes of regulatory fit. By meta-analyses, the weak effect in one third of regulatory fit studies, whose regulatory forms were mismatched or partially matched, decreased the overall fit effect and increased the heterogeneousness among regulatory fit studies. However, a strong and consistent regulatory fit effect was found in well-matched of regulatory forms. By examining and extending regulatory forms to measurement, activation, and regulatory fit studies, this paper offers further understanding of the mechanisms of regulatory focus.
Synchronization induced by temporal delays in pulse-coupled oscillators.

We derive return maps and phase diagrams to identify mechanisms of synchronization of pulse-coupled oscillators and emphasize the importance of temporal delays and inhibitory coupling. Optimum synchronization between two oscillators is obtained for inhibitory coupling, where delays give rise to stable in-phase synchronization; those with excitatory coupling only synchronize with a phase lag. In large ensembles of globally coupled oscillators the delayed interaction leads to new collective phenomena like synchronization in multistable clusters of common phases for inhibitory coupling; for excitatory coupling a mechanism of emerging and decaying synchronized clusters prevails.
Hypertension Grand Rounds Management of Antiangiogenic Therapy-Induced Hypertension

Angiogenesis, or the formation of new blood vessels, is essential for solid tumor growth and metastasis, and it is regulated by proangiogenic soluble mediators, including the vascular endothelial growth factor (VEGF). Antiangiogenic drugs that block the VEGF signaling pathway prolong progression-free survival (PFS) in several cancers and are now in broad clinical use to treat advanced-stage solid tumors. Hypertension is among the most common toxicities of this therapeutic class, with recent meta-analyses reporting the incidence of hypertension induced by a single antiangiogenic agent to be 20%, and single studies have reported incidence as high as 87%. Thus, the appropriate diagnosis and management of antiangiogenic therapy-induced hypertension are now common clinical problems. In this report, we present a patient who developed antiangiogenic therapyinduced hypertension and review the mechanisms, management, and emerging questions in this evolving field.
Erzählkompetenz, Repräsentationen und Theory of Mind: Gemeinsamkeiten und Unterschiede

The development of thinking with all its different aspects is not alone a theme of cognitive psychology, but more and more of developmental psychology, in particular with psychoanalytic background. At the latest since the important work by Fonagy, Gergely, Jurist and Target (2004) we are aware of the possible impact of an impaired mentalisation capacity for psychic development. In this article we discuss three aspects of thinking: narrative competence, representations and mentalisation and theory of mind; we will limit ourselves to children in first and second year of Kindergarten who are between 5 and 6 years old. The narrative competence is a really rich and interesting construct as well as a psychic ability connecting cognitive and affective aspects in a most interesting way. Representations of relationships are the main issue of several theories in developmental psychology. The concept of theory of mind has become very significant in cognitive psychology. After a detailed introduction of the central concepts, in the empiric part we will show how aspects of narrative competence are associated with advanced theory of mind skills. Children having passed a theory of mind test respond more to the conflict of the story and show less avoidant strategies in their narratives. Further analyses revealed that only girls showed the expected differences. Therefore an advanced theory of mind capacity gives girls a scope for development to get involved with more difficult conflicts in stories, which enables them to work through more contentious situations.
Free Proonite R-trivial Monoids

R esum e: Cet article est consacr e a l' etude de la structure des semigroupes d'op era-tions implicites sur R, la pseudovari et e des semigroupes R-triviaux. Nous donnons deux descriptions compl ementaires de ces semigroupes : d'abord a l'aide d'ordinaux etiquet es; puis en utilisant des arbres etiquet es innnis, de profondeur nie. Dans la premi ere repr esentation, le produit d'op erations implicites admet une caract erisation el ementaire. Dans la seconde, c'est la topologie des op erations implicites qui est rendue le mieux visible. Une etude similaire est men ee pour les op erations implicites sur DRG, l'analogue non ap eriodique de R. Cette derni ere etude nous conduit a la description de la vari et e de langages associ ee a DRG et au calcul de certains sup de pseudovari et es. Abstract: This article is concerned with the structure of semigroups of implicit operations on R, the pseudovariety of all R-trivial semigroups. We give two complementary descriptions for these semigroups: rst by means of labeled ordinals, and second by means of labeled innnite trees of nite depth. In the rst representation, the product of implicit operations has a simple characterization. In the second one, the topology on implicit operations is best visible. A similar study is conducted for the implicit operations on DRG, the non-aperiodic analogue of R. This leads to a description of the corresponding variety of recognizable languages and to the computation of certain joins of pseudovarieties. Monoids in which all regular elements lie in groups are not very far from the much better understood completely regular monoids, but, nevertheless, the step from one class of monoids to the other is rather nontrivial. Thus, as pointed out by Sch utzenberger 22], the pseudovariety DS of all nite monoids in which all regular elements lie in groups should play an important role in the theory of nite monoids. The monoids of implicit operations on pseudovarieties of monoids have been shown to be worthy objects of study: the topological and algebraic structure of these compact monoids contains valuable information on the structure of the nite monoids in the pseudovariety, and on the associated variety of recognizable languages 1, 2, 5]. Many applications of this approach can be found, for instance,
Residue-based fusion of denoised images by different filter banks

The paper presents a new method to improve image quality that exploits the residue-based fusion of three denoised images using different two-dimensional (2-D) filter banks. First, the three denoised images are obtained by applying the BLS-GSM algorithm to the decompositions of a noisy image by the steerable pyramid, nonsubsampled contourlet, and 2-D separable oversampled DFT filter bank. The denoised images exhibit inhomogeneous quality relevant to local details of the image and the underlying filter bank. Second, the local quality of denoised images is measured by the local variances of the residual image, the noisy image minus the denoised image. Third, the three denoised images are fused into a clean image with the help of the local quality measures. The experimental results show that the proposed method improves the quality of denoised images visually and in the sense of peak signal-noise-ratios (PSNR).
Ability grouping is not just tracking anymore

The No Child Lett Behind legislation, with its emphasis on conducting scientifically based research, has reopened the door to a set of instructional and curricular practices left for dead in light of the scathing criticism of Oakes and Slavin in the 1980s, mainly ability grouping. This article represents a review of the literature of best practices, both instructional and curricular, that may lead to increased achievement among America's gifted and talented youth, whether they reside in an enrichment or resource room or the regular classroom. The review suggests that flexible ability grouping, combined with appropriate curricular revision or differentiation, may result in substantial achievement gains both for average and high ability learners. It is imperative that researchers in the field of gifted education take the lead in this endeavor so that no child, including the gifted and talented, will be left behind.
Actinomycetes Diversity among rRNA Gene Clones and Cellular Isolates from Sambhar Salt Lake, India

The vertical stratification of actinomycetes diversity in Sambhar salt lake (India's largest salt lake) was investigated by using cultivable and uncultivable approaches. The isolates from cultured approaches were clustered on the basis of cultural, morphological, biochemical, and cell wall characteristics, and results were further strengthened by 16S rDNA-RFLP into five major groups. 16S rDNA sequencing of the representative isolates from each clusters was identified as belonging to Streptomyces, Actinopolyspora, Microbispora, Saccharopolyspora, and Actinoplanes genera, while culture independent group was established as Streptomyces (130 clones, 20 OTUs), Micromonospora (96 clones, 7 OTUs), Streptosporangium (79 clones, 9 OTUs), Thermomonospora (46 clones, 8 OTUs), and Dactylosporangium (58 clones, 8 OTUs). The diversity assessment using Shannon and Wiener index was found to be 1.55, 1.52, 1.55, and 1.49 from surface lake water, at depth of 1.5 m, shallow layer of water with algal population, and finally at depth of 2.5 m, respectively. We observed diversity in terms of the species richness as Streptomyces is dominant genus in both culture dependent and culture independent techniques followed by Microbispora (culture dependent methods) and Micromonospora (culture independent method) genera, respectively.
The UNC Graph Server: A Distributed Hypermedia Data Management System

Abstract : Our project is studying the process by which groups of individuals work together to build large, complex structures of ideas and is building a distributed hypermedia system to support that process. This description focuses on the hypermedia data management system--which we call a graph server--we are developing to support groups of collaborators working on individual workstations within a distributed computing environment. The discussion covers the graph- based data model provided by the server to client hypermedia programs as well as the architecture of the system. A number of research issues are raised and discussed in context including: partitioning the hypermedia graph; an open, extensible architecture for applications; composite objects; anchored links; and the integrity, consistency, and completeness of the artifact as a whole.
Weight Loss and the Renin-Angiotensin-Aldosterone System

The renin-angiotensin-aldosterone system has been causally implicated in obesity-associated hypertension. We studied the influence of obesity and weight reduction on the circulating and adipose tissue renin-angiotensin-aldosterone system in menopausal women. Blood samples were analyzed for angiotensinogen, renin, aldosterone, angiotensin-converting enzyme activity, and angiotensin II. In adipose tissue biopsy samples, we analyzed angiotensinogen, renin, renin-receptor, angiotensin-converting enzyme, and angiotensin II type-1 receptor gene expression. Obese women (n=19) had higher circulating angiotensinogen, renin, aldosterone, and angiotensin-converting enzyme than lean women (n=19), and lower angiotensinogen gene expression in adipose tissue. Seventeen women successfully participated in a weight reduction protocol over 13 weeks to reduce daily caloric intake by 600 kcal. Body weight was reduced by −5%, as were angiotensinogen levels by −27%, renin by −43%, aldosterone by −31%, angiotensin-converting enzyme activity by −12%, and angiotensinogen expression by −20% in adipose tissue (all P<0.05). The plasma angiotensinogen decrease was highly correlated with the waist circumference decline (r=0.74; P<0.001). Weight and renin-angiotensin-aldosterone system reductions were accompanied by a −7-mm Hg reduced systolic ambulatory blood pressure. These data suggest that a 5% reduction in body weight can lead to a meaningfully reduced renin-angiotensin-aldosterone system in plasma and adipose tissue, which may contribute to the reduced blood pressure.
A Novel Visual Data Mining Module for the Geographical Information System gvSIG

The exploration of large GIS models containing spatio-temporal information is a challenge. In this paper we propose the integration of scientific visualization (ScVis) techniques into geographic information systems (GIS) as an alternative for the visual analysis of data. Providing GIS with such tools improves the analysis and understanding of datasets with very low spatial density and allows to find correlations between variables in time and space. In this regard, we present a new visual data mining tool for the GIS gvSIG. This tool has been implemented as a gvSIG module and contains several ScVis techniques for multiparameter data with a wide range of possibilities to explore interactively the data. The developed module is a powerful visual data mining and data visualization tool to obtain knowledge from multiple datasets in time and space. A real case study with meteorological data from Villa Clara province (Cuba) is presented, where the implemented visualization techniques were used to analyze the available datasets. Although it is tested with meteorological data, the developed module is of general application in the sense that it can be used in multiple application fields related with Earth Sciences.
