On the Space of Trajectories of a Generic Vector Field

This paper describes the construction of a canonical compactification of the space of trajectories and of the unstable/stable sets of a generic gradient like vector field on a closed manifold as well as a canonical structure of a smooth manifold with corners of these spaces. As an application we discuss the geometric complex associated with a gradient like vector field and show how differential forms can be integrated on its unstable/stable sets. Integration leads to a morphism between the de Rham complex and the geometric complex.
The Redshift and the Host Galaxy of GRB 980613: A Gamma-Ray Burst from a Merger-induced Starburst?

We present the optical and near-IR identification and spectroscopy of the host galaxy of gamma-ray burst GRB 980613. The burst was apparently associated with the optically (rest-frame UV) brightest component of an apparent system of at least five galaxies or galaxy fragments, at least two of which are at a redshift of z = 1.0969. The component we identify as the host galaxy shows a moderately high unobscured star formation rate, SFR ~ 5 M☉ yr-1, but a high SFR per unit mass, indicative of a starburst. The image components show a broad range of (R-K) colors, with two of them being very red, possibly due to dust. The overall morphology of the system can be naturally interpreted as a strong tidal interaction of two or more galaxies, at a redshift where such events were much more common than now. Given the well-established causal link between galaxy mergers and starbursts, we propose that this is a strong case for a GRB originating from a merger-induced starburst system. This supports the proposed link between GRBs and massive star formation.
one or two languages ? An eye movement study of cognate facilitation in L 1 and L 2 reading

This study examined how noun reading by bilinguals is influenced by orthographic similarity with their translation equivalents in another language. Eye movements of DutchEnglish bilinguals reading an entire novel in L1 and L2 were analyzed. In L2, we found a facilitatory effect of orthographic overlap. Additional facilitation for identical cognates was found for later eye movement measures. This shows that the complex, semantic context of a novel does not eliminate cross-lingual activation in natural reading. In L1 we detected non-identical cognate facilitation for first fixation durations of longer nouns. Identical cognate facilitation was found on total reading times for high frequent nouns. This study is the first to show cognate facilitation in L1 reading of narrative text. This shows that even when reading a novel in the mother tongue, lexical access is not restricted to the target language.
Dancing with Up-stream Directives in the Supply Chain : Suppliers‘ Innovation Performance

This study contributes to the innovation management literature by clarifying suppliers’ innovation and performance antecedents in supply chains. Suppliers are highly important as they trigger innovations in supply chains. Suppliers have to cope with upstream directives which manufactures impose on them to improve the coordination of several suppliers’ innovative modules to the product concept. This study of IT suppliers in Germany finds that suppliers increasingly encounter upstream directives in high uncertainty environments. Upstream directives promote radical innovation and business performance, yet negatively affect incremental innovations.
Mechanisms and fitness effects of interspecific information use between migrant and resident birds

Interactions with potential competitors are an important component of habitat quality. Due to the costs of coexistence with competitors, a breeding habitat selection strategy that avoids competitors is expected to be favored. However, many migratory birds appear to gain benefits from an attraction to the presence of resident birds, even though residents are assumed to be competitively dominant. Thus far the mechanisms of this habitat selection process, heterospecific attraction, are unknown, and the consequences for resident birds of migrant attraction remain untested. Through heterospecific attraction, migrants may gain benefits if the density or territory location of residents positively reflects habitat quality, and/or they gain benefits through increased frequency of social interactions with residents in foraging or predator detection. In this experiment, we examined the reciprocal effects of spatial proximity on fitness-related traits in migrant pied flycatcher (Ficedula hypoleuca) and resident great tit (Parus major) by experimentally forcing them to breed either alone or in close proximity to each other. Surprisingly, great tits bore all the costs of coexistence while flycatchers were unaffected, even gaining slight benefits. In concert with an earlier study, these results suggest that flycatchers use tits as information about good-quality nest-site locations while benefits from social interactions with tits are possible but less important. We suggest that utilizing interspecific social information may be a common phenomenon between species sharing similar resource needs. Our results imply that the effects of interspecific information use can be asymmetric and may therefore have implications for the patterns and consequences of species coexistence.
Friday on My Mind: The Relation of Partying With Antisocial Behavior of Early Adolescents. The TRAILS Study

The relation between partying and antisocial behavior was investigated using a sample of Dutch early adolescents (T2: N=1,076; M age=13.52). Antisocial behavior was divided into rule-breaking and aggressive behavior. Using a goal-framing approach, it was argued that the relation of partying to antisocial behavior depends on the way the need to belong is realized. Girls, in early adolescence often physically more mature than boys, are likely to seek older and, thus, often more antisocial boys for partying. Unpopular adolescents are likely to be among themselves when partying, and their feeling of exclusion is likely to lead to antisocial behavior. The findings show that girls who party are indeed at a greater risk of engaging in antisocial behavior, as are unpopular girls and boys.
Sugar Prices in Poland and Their Determinants

The sugar market in the EU is among the most regulated food markets in the world. This regulation is based on production quotas and foreign trade regulations. At the same time, individual links of the marketing chain are characterised by highly varied degree of concentration, which – in the conditions of strong market protection – creates the potential for monopolistic practices and the so-called monopolistic margins. In this context, the paper aims at empirical assessment of changes in sugar prices in Poland and identification of their determinants. The study was based on monthly sugar prices in Poland, the EU and across the world in 2000-2014. Time series models were used to assess correctness. The conducted research indicates that sugar production and prices in Poland and in the EU are largely determined by the market regulation system, while the sugar market reform had little effect on increasing the interrelations between the EU prices and world prices. At the same time, the retail and selling prices are strongly interrelated and these interrelations can be non-linear.
A NOVEL ROUTING PROTOCOL WITH IMPROVED PERFORMANCE FOR MANET IN ADVERSARIAL ENVIRONMENT

Security issues have been emphasized when mobile ad hoc networks (MANETs) are employed into military and aerospace fields. In adv ersary environments, Anonymous communications are important for many applications of the mobile a d hoc networks (MANETs) deployed. A requirement on the network is to provide unidentifi ability and unlinkability for mobile nodes and thei r traffics. Eventhough a number of anonymous secure routing protocols have been proposed, the requirement is not fully satisfied. A new routing p rotocol, i.e., authenticated anonymous secure routing (AASR), to satisfy the requirement and defe nd the attacks is being proposed in this paper. The key-encrypted onion routing with a route secret ver ification message, is designed to prevent intermediate nodes from inferring a real destinatio n. Simulation results have demonstrated that the proposed Novel protocol is effective with improved performance when compared with the existing protocols. The salient feature of AASR is that when trust relationships in such among nodes, there is no need for a node to request and verify certificat es every time which reduces the computation overheads. Meanwhile, with neighbors' trust recommendations, a node can make objective judgement about another node's trust-worthiness to maintain t he whole system at a certain security level.
Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness

Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.
EURASIAN JOURNAL OF BUSINESS AND MANAGEMENT

The aim of this paper is to shed more light on the significant effect that leadership self-efficacy and shared leadership have on organizational performance. The purpose of this study is to contribute to the research on shared leadership that is still in its early stages. Trust, as a component of social capital, is considered the essential criteria for an emotionally aware leader. Trust enables individuals to channel their energy on those aspects of work for which they have real passion. Emotions, whether positive or negative, stimulate and steer organizational performance and behavior. Humor can reduce absenteeism; improve levels of effort, health and energy, all of which influence the levels of performance. The case study methodology focused on a profit-oriented Information Technology SME. A questionnaire was distributed to ascertain how leadership self-efficacy might influence shared leadership and affect organizational performance. The study entails the presupposition that those managers who have regard for the self-efficacy leadership attributes cluster will have a higher probability of improving both perceived and actual employee performance. The results of this study seem to demonstrate that emphasis is placed on the problem-solving attributes of leadership self-efficacy. This will result in a positive impact on the organizational performance as a whole. This paper is of added value for scholars and organizations in the knowledge economy.
Forecast Model Applications of Satellite-derived Cloud Parameters

Abstract : Microphysical characteristics in maritime cloud have significant control on cloud layer evolution, electromagnetic propagation, cloud aerosol interactions, visibility, and aircraft flight hazards. While the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) model may not in the immediate future explicitly represent cloud microphysical parameters, the relationship of cloud structure to the predicted variables must be assessed, particularly when considering physical or radiative parameterizations. Electromagnetic signal propagation through the atmosphere is directly influenced by the size and composition of atmospheric particles. Cloud droplet size, particularly at cloud top in the marine atmospheric boundary layer (MABL), plays a role in the rate at which turbulent entrainment produces aerosol via evaporation or removes aerosol via collection by droplets. The droplet size distribution also controls the effectiveness of the stochastic collision coalescence process in producing drizzle or rain, thereby also impacting the evaporative source (or collection loss) of aerosol during drop sedimentation below cloud. These processes can be incorporated into combined aerosol cloud simulation models by explicit or parameterized treatments.
Latest evidence on using hormone replacement therapy in the menopause

Hormone replacement therapy (HRT) is the most effective treatment for symptoms of estrogen deficiency. When HRT is individually tailored women gain maximum advantages and the risks are minimised. Several types and regimens of HRT and different routes of delivery exist. Results from studies using only one type and route may not therefore apply to all users. The use of HRT is an individual decision, which a woman can only make once she has been given correct information and advice from healthcare professionals. HRT should be recommended in women with premature ovarian insufficiency with advice to continue until the average age of the menopause at 51.4 years.
Cross-Cultural Comparison of Russian and German Students’ Learning Motivation Traits

The Integration of Russia into European educational space invoke many questions, one of them is a cross-cultural universality of learning motivation. In this paper we discuss the methodology of a learning motivation traits questionnaire and results of its cross-cultural validation at the sample of 332 German and 865 Russian students. In our study we found measurement invariance of intrinsic orientation, test anxiety and performance avoidance scales of Russian and German form of questionnaire. We showed also invariance of learning motivation traits structure. At the same time we found differences in extrinsic orientations of Russian and German students
Low Rank Parity Check codes and their application to cryptography

In this paper we introduce a new family of rank metric codes: the Low Rank Parity Check codes for which we propose an e cient probabilistic decoding algorithm. This family of codes can be seen as the equivalent of classical LDPC codes for the rank metric. We then propose to use these codes for cryptography in the McEliece encryption setting. At the di erence of previous encryption algorithms based on rank metric -especially based on Gabidulin codes -, the codes we use have a very poor structure. Our cryptosystem can be seen as an equivalent to the NTRU cryptosystem [16] (and also to the more recent MDPC[23] cryptosystem) in a rank metric context. Overall our system permits to achieve a very low public key of 1517 bits for a security of 280, moreover our system is very fast, with a decryption failure which can be made arbitrarily small.
Quaternary refugia and secondary contact in the southern boundary of the Brazilian subregion: comparative phylogeography of freshwater fish

Freshwater fish are an ideal model to illustrate how climate-tectonic changes affect the distribution of genetic variation. Freshwater bodies are extensively affected by environmental changes, with streams even changing their courses in the most extreme cases. Fortunately, this situation is reflected in the genetic composition of populations and may currently be inferred from the study of mitochondrial DNA molecular markers. Here we analyze and compare the phylogeographic patterns of the species Corydoras paleatus and Jenynsia multidentata at the southern limit of the Brazilian subregion. These basins are isolated in the current hydrogeographic pattern due to geologic and paleoclimatic changes. Our results support a concurrent pattern for both species. Some lineages have persisted in the area under adverse climate conditions, possibly in environmental refuges, while other lineages may have colonized the area later by means of paleodrainages connections. In addition, the presence of independent, greatly diverging lineages, even within the same watercourses, suggests secondary contact between these lineages. This work represents a first approach to understand how geologic and paleoclimatic changes have affected the distribution of genetic variation in the Southern Pampean Area.
Tumidotheres, a New Genus for Pinnotheres margarita Smith, 1869, and Pinnotheres

The genus Tumidotheres is erected to receive its type species Pinnotheres margarita Smith, 1869, from the East Pacific, and P. maculatus Say, 1818, from the West Atlantic. It differs from other pinnotherid genera principally in 3 features: (1) the gastric and cardiac regions are separated from the branchiohepatic area by depressions, all these regions tumid; (2) the palp of the third maxilliped is composed of 3 articles, with the carpus shorter than the spatulate propodus, the dactylus narrowly spatulate, inserted medially on the propodal inner margin and not overreaching the tip of this latter article; and (3) male and female abdomen composed of 7 free abdominal somites. An analysis of morphology of several postplanktonic stages of T. (formerly Pinnotheres) margarita suggested that this species should be considered as a senior synonym of P. pubescens (Holmes, 1894), which apparently was described from a hard-stage female. In addition, the life history, phylogenetic relationships, and larval morphology of Tumidotheres are discussed.
FBK @ IWSLT 2014 – ASR track

This paper reports on the participation of FBK in the IWSLT 2014 evaluation campaign for Automatic Speech Recognition (ASR), which focused on the transcription of TED talks. The outputs of primary and contrastive systems were submitted for three languages, namely English, German and Italian. Most effort went into the development of the English transcription system. The primary system is based on the ROVER combination of the output of 5 transcription subsystems which are all based on the Deep Neural Network Hidden Markov Model (DNN-HMM) hybrid. Before combination, word lattices generated by each sub-system are rescored using an efficient interpolation of 4-gram and Recurrent Neural Network (RNN) language models. The primary system achieves a Word Error Rate (WER) of 14.7% and 11.4% on the 2013 and 2014 official IWSLT English test sets, respectively. The subspace Gaussian mixture model (SGMM) system developed for German achieves 39.5% WER on the 2014 IWSLT German test sets. For Italian, the primary transcription system was based on hidden Markov models and achieves 23.8% WER on the 2014 IWSLT Italian test set.
Some Lessons From the Financial Crisis for the Economic Analysis

The economics profession in general, and economic forecasters in particular, have faced some understandable criticism for their failure to predict the timing and severity of the recent economic crisis. In this paper, we offer some assessment of the performance of the Economic Analysis conducted at the ECB both in the run up to and since the onset of the crisis. Drawing on this assessment, we then offer some indications of how the analysis of economic developments could be improved looking forward. The key priorities identifi ed include the need to: i) extend existing tools and/or develop new tools to account for important feedback mechanisms, for instance, improved real-fi nancial linkages and non-linear dynamics; ii) develop ways to handle the complexity arising from the presence of multiple models and alternative economic paradigms; and iii) given the limitations of point forecasts, to further develop risk and scenario analysis around baseline projections.

Identifying high and low serum-ascites albumin gradient in ascitic fluid by the point of care dipstick test

Objective: To evaluate the capability of ascitic fluid dipstick results for pH, glucose, and protein in order to predict a low serum-ascites albumin gradient (SAAG) at the bedside of the patient in the emergency department (ED). Methods: This prospective cross-sectional study was conducted during one year in the ED of Afzalipour hospital in Kerman, Iran. All patients with diagnostic or therapeutic paracentesis of ascitic fluid were considered as eligible patients. Exclusion criteria included clinical suspicion for spontaneous bacterial peritonitis (SBP), any contraindications to paracentesis, and patients’ refusal to participate in the study. Dipstick values were obtained at the bedside, and SAAG was calculated after the determination of serum and ascitic fluid albumin by laboratory. A low SAAG ascitic fluid was defined as the study outcome. We also used our study population as a test group to evaluate an equation proposed in one previous study: K = 0.012 Protein−0.012 Glucose−3.329 pH+23.498 Results: A total of 50 patients were enrolled in the study. Based on multivariate regression analysis, dipstick values for protein and glucose were independently predictive of a low SAAG ascitic fluid (P = 0.23, OR = 1.04; and P = 0.001, OR = 0.81, respectively). The formula proposed in one of the previous studies was tested by our data set, with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) at 84%, 83%, 84%, and 80%, respectively. Conclusion: Dipstick test of ascitic fluid for pH, glucose, and protein has an acceptable sensitivity and specificity as a point of care test, but it cannot be recommended as a substitute for SAAG determination based on the current findings.

Accurate algebraic cost models enable for early cost estimation as well as for cross-level optimization over architecture, micro-architecture and circuit-level using a rich set of parameters. Quantitative results for an exemplary QRD application, implemented in 40-nm CMOS technology, are presented.
Genetic Affinity Between Two Ethnically Diverse Caste Groups of North India: A Study Based Upon 15 Microsatellite Loci

Abstract This study attempts to understand the genetic structure and affinity among two major ethnic caste groups viz., Jat and Kurmi of north India in order to examine the effect of geographical as well as occupational proximity among these groups and their genetic relationship with two other predominant populations of the same region. The genetic structure and diversity of the studied populations was examined by analyzing polymorphism at 15 microsatellite loci. The Jat and Kurmi populations displayed high degree of heterozygosity with average heterozygosity in the range of 0.788 to 0.796 at all the studied loci. The most frequent allele common for the populations was observed at four loci (D21S11, vWA, D8S1179 and D16S539) while the remaining eleven loci showed differences in their allele frequency. The level of intra-population genetic diversity is found significantly high. The coefficient of gene differentiation wars found to be low (average GST is 1.1 per cent and ranges between 0.2% at D16S539 to 2.5% at D13S317) across the loci, indicating close affinity between the two occupational caste groups. Clustering pattern based on neighbouring joining tree reveals two clear clusters, one for Kurmi and Jat and other for Khatri and Thakur populations. The results strongly demonstrate that the geographical as well as occupational proximity attributes significantly to genetic affinity between the studied populations.
