Less fixation on the eyes is associated with severe social disability in individuals with autism spectrum disorder

Objective: Previous studies’ findings regarding fixation on the eyes or mouth and level of social disability in people with autism spectrum disorder (ASD) are controversial. This meta-analysis aimed to assess the association between eye gaze patterns and social impairments. Methods: We searched the PubMed, Embase, and PsycINFO databases for studies that reported the Pearson’s correlation coefficient (r) between time fixated on the eyes or/ and mouth in an eye-tracking experiment and level of social disability in people with ASD. Subgroup analyses were conducted according to stimuli type. Results: Twelve cross-sectional studies comprising 15 study groups with 317 participants were included. The amount of time fixated on the eyes was linked to the level of social disability (r = -0.300, 95% CI -0.397 to -0.197). The result was more pronounced when the patients viewed image stimuli (r = -0.414, 95% CI -0.565 to -0.236, I2 = 0%). Furthermore, we found a significant relationship between mouth fixation and social disability when patients viewed images (r = 0.319, 95% CI -0.080 to 0.530, I2 = 0%), but not when they viewed videos (r = -0.197, 95% CI -0.178 to 0.523, I2 = 80.4%). Conclusions: This study showed that less eye fixation was associated with greater social impairment in individuals with ASD, providing further evidence that reduced eye fixation is a strong hallmark of the early detection, diagnosis and prediction of social deficits in ASD. Future studies should further investigate the relationship between mouth fixation and social impairment.
Efficacy of tamoxifen and thymoquinone on tumor development, lipid peroxidation, and total antioxidant capacity in DMBA induced mammary carcinoma in female Sprague-Dawley rats

Tamoxifen (TAM) is a drug used for treatment and prevention of breast cancer. However, TAM has been reported to induce liver tumors in several animal models due to overproduction of free radicals and lipid peroxidation. Thymoquinone (TQ), from Nigella sativa seeds, is a Middle East natural medicine and it has been used to treat a number of diseases, including cancer. The aim of my study was to investigate the effect of TQ and TAM on tumor development, lipid peroxidation level, and total antioxidant capacity in DMBA treated female Sprague-Dawley rats. Five groups of 10 rats (control, DMBA, TAM, TQ, and TAM+TQ) were used. Mammary tumors were induced by DMBA which was given by oral gavage to four groups: DMBA, DMBA+ TAM, DMBA+ TQ, and DMBA+ TAM & TQ. The control group received tap water only. Starting three weeks later, TAM and/or TQ were administered daily for 10 weeks. Mammary tumors were found in two DMBA treated animals. There was coloration in the mammary glands in four other DMBA treated animals. No mammary tumors or mammary gland coloration was observed in other groups. Rats treated with TAM showed a significantly higher level of lipid peroxidation when compared to control (P<0.05). However, the administration of TQ together with TAM showed significant decrease in lipid peroxidation level compared to treatment with TAM alone (P<0.05). Total antioxidant capacity did not differ among the groups (P=0.791). Average body weight gain during 12 weeks differed significantly among the groups (P<0.001). TAM treated rats had a lower body weight gain when compared with other animals and this was not ameliorated by TQ. In conclusion, both TAM and TQ appeared to prevent tumor induction by DMBA.TAM had two adverse effects on the rats: increasing in lipid peroxidation levels and reduction in body weight gain. TQ ameliorated the adverse effect of TAM on lipid peroxidation but not body
Cosmic ray acceleration and escape from supernova remnants

Galactic cosmic ray (CR) acceleration to the knee in the spectrum at a few PeV is only possible if the magnetic field ahead of a supernova remnant (SNR) shock is strongly amplified by CR escaping the SNR. A model formulated in terms of the electric charge carried by escaping CR predicts the maximum CR energy and the energy spectrum of CR released into the surrounding medium. We find that historical SNR such as Cas A, Tycho and Kepler may be expanding too slowly to accelerate CR to the knee at the present time.
On cofree S-spaces and cofree S-flows

Let S-Tych be the category of Tychonoff S-spaces for a topological monoid S. We study the cofree S-spaces and cofree S-flows over topological spaces and we prove that for any topological space X and a topological monoid S, the function space C(S,X) with the compact-open topology and the action s · f = (t → f(st)) is the cofree S-space over X if and only if the compact-open topology is admissible and Tychonoff. Finally we study injective S-spaces and we characterize injective cofree S-spaces, when the compact-open topology is admissible and Tychonoff. As a consequence of this result, we characterize the cofree S-spaces and cofree S-flows, when S is a locally compact topological monoid.
Identity and Efficacy: Latinos in the United States

QUESTIONS ABOUT THE EFFECT OF IDENTITY ON POLITICAL ATTITUDES AND BEHAVIOR IN THE UNITED STATES ARE INCREASINGLY IMPORTANT AS ITS POPULATION BECOMES MORE DIVERSE. THE PRIMARY DRIVER OF THAT INCREASED DIVERSITY IS THE EXPANSION OF THE LATINO POPULATION. MOST RESEARCH FOCUSES ON DIFFERENCES BETWEEN VARIOUS ETHNIC GROUPS. THIS RESEARCH PROJECT SEEKS TO UNDERSTAND THE EFFECT OF IDENTITY STRENGTH WITHIN THE LATINO POPULATION ON ATTITUDES ABOUT GOVERNMENT. USING THE 2006 LATINO NATIONAL SURVEY, THE ROLE OF IDENTITY ON EFFICACY IS EXPLORED. THE RESULTS INDICATE THAT EFFICACY AMONG LATINOS IS RELATED TO IDENTITY. WE ALSO FIND RESULTS THAT REINFORCE THE PRESENCE OF CLASSIC INFLUENCES ON EFFICACY SUCH AS SOCIOECONOMIC STATUS AND POLITICAL ENGAGEMENT. 1 Salzman and Reilly: Identity and Efficacy: Latinos in the United States Published by Carroll Collected, 2015

The trophic roles of microzooplankton in marine systems

Calbet, A. 2008. The trophic roles of microzooplankton in marine systems. - ICES Journal of Marine Science, 65: 325-331.Microzooplankton (here defined as <200 μm grazers) are key components of marine foodwebs. Their grazing significantly affects primary producers and usually exceeds that of mesozooplankton. However, our knowledge of the detailed roles that microzooplankton taxa play in marine ecosystems is surprisingly limited. Here, I identify the main protists responsible for most of the grazing impact on phytoplankton in two contrasting marine ecosystems: oligotrophic waters and productive waters, such as upwelling systems, spring blooms, and other blooms in nearshore and estuarine systems. Evidence indicates that pico- and nano-sized flagellates, which are routinely included with the microzooplankton size class of protists, appear to be the main grazers of phytoplankton in oligotrophic habitats, whereas heterotrophic and mixotrophic dinoflagellates are candidates for the dominant grazing impact in upwelling and other productive ecosystems. Microzooplankton are also important contributors to mesozooplankton diet, especially in oligotrophic areas, although the strength of the mesozooplankton-microzooplankton link is traditionally overlooked in plankton studies. As a final remark, this review emphasizes the need to develop suitable methods for studying the role of microbial grazers in the dynamics of marine ecosystems.
Predicting Synchronization of Three Mutually Inhibiting Groups of Oscillators with Strong Resetting

Neural populations encode sensory information, memory and motor patterns through electro-chemical firings, which propagate throughout the nervous system via synapses, a structure that couples neurons together. A powerful tool to investigate synchronization issues in such systems are the Phase Resetting curves. However these are best suited for brief and small perturbations. Motivated by the observation of strong inhibition in some neural circuits, we investigate a resetting model with simila r features to a known neural population called striatum, in which three groups of neurons inhibit themselves. The model is intrinsically based on Kuramoto oscillators, and is analytically treatable. We derive a synchronization threshold in this model, and show numerically an unexpected complex dynamics.
Market Share Evolution , Size Spillovers and Organizational Forgetting in Retail Chain Dynamics ∗

A firm’s decision to expand or contract has long term strategic implications for not only its market outcomes but also industry structure and evolution. A “Chandlerian” view suggests that once firms become large they persist in being dominant. An alternative “Schumpeterian” view emphasizes transience in market shares. This paper examines the link between firm size and market performance by developing a dynamic oligopoly model in which firm size is endogenous to decisions to add or subtract retail stores, and market share transitions result from strategic interaction between firms. Through a firm specific unobservable that incorporates the spillovers of current firm size on future chain profitability, the model allows for heterogeneity in the dynamic link between firm size and future market outcomes. Furthermore, it allows for heterogeneity in how well firms retain such advantages via organizational forgetting. This seemingly intractable dynamic game is estimated by extending the Bajari, Benkard and Levin (2007) two-step estimation method to incorporate a particle filter procedure to account for such serially correlated unobservables with endogenous feedback. The empirical analysis is based on data for Canadian hamburger retail chains from their inception in 1970 to 2005. There is evidence not only of spillovers of firm size and organizational forgetting but more importantly of heterogeneity in these across firms. The heterogeneity in the dynamic linkage between firm size and profitability helps explain why some firms become dominant and others falter as they evolve, with consequences for market structure and concentration.
Pseudo-nitzschia australis on French Atlantic coast - an unusual toxic bloom

The occurrence of the toxic diatom Pseudo-nitzschia australis was first suspected in a water sample from Bay of Brest, France, in 1995 (Fig. 1). At this time, and because of very low number of cells, the identification could not be confirmed by Scanning Electron Microscopy (SEM). In autumn 2004, this species was again reported, and in association with P. multiseries, suspected to be the source of domoic acid (DA) in king scallops (Pecten maximus) from the Bay of Seine (English Channel) [1]. Since 2006, it has been encountered every year at low concentrations in either spring or autumn along the Atlantic coast of Brittany. This year, it was first observed in early March in the Bay of Douarnenez and bloomed a week later in the “Pertuis Charentais” area with densities exceeding 106 cells L-1 (Fig. 1). It then for more than a month remained noticeable (from 105 to 106 cells L-1) in several areas of the Atlantic coast (Fig. 1). At the same time, the monitoring network (REPHY of Ifremer) detected domoic acid far above the EU-regulatory limit of 20 mg DA/ Kg tissue in shellfish (up to 10 times the safety threshold), leading to the prohibition of harvesting and sale of scallops during several weeks. In contrast to other years where toxic blooms were dominated by species of the Pseudo-nitzschia pseudodel ica t i s s ima/cusp ida ta complex [2] as defined by Lundholm et al. [3], this year was notable for a species of the Pseudo-nitzschia seriata complex sensu Hasle [4]. An identification key using features observable in Light Microscope (LM) led us to think that it was Pseudonitzschia australis with asymmetrical lanceolate valves, a width varying from 7.0 to 8.9 μm, apices slightly rostrate and a 23-31% overlap of cells in chains (Fig. 2). SEM examination of valves showed that there was no central Fig. 1.

Treatment of Toxic Organics in Industrial Wastewater using Activated Sludge Process

In Pakistan besides pesticide contamination from agricultural field, the manufacturing industriesare also contributing relatively high quantities of toxic pesticides into the environment. These pesticides maybe toxic, mutagenic or carginogenic and may be bioaccumulated or biomagnified by the biota. Because ofpersistent nature of pesticides, its removal from environmental system become difficult. The effective operation of wastewater treatment plant plays an important role in minimizing the release of toxic compounds into the environment. Research on the removal of toxic organics using the biological treatment plants is limited. In this study the bacterial isolate, IES-PS-1, was used to assess its potential for Cypermethrin degradation in activated sludge process. The experimental findings indicate that by maintaining the optimum operating conditions in the reactor, the removal efficiency significantly improved and > 88 % degradation observed at 80 mg/L dose. However, the complete removal of Cypermethrin, determined by High Performance Liquid Chromatography (HPLC), occurred at 20mg/L during 48 hour treatment. In addition, a considerable reduction in the sludge volume and chemical oxygen demand (COD) was also observed, producing an acceptable effluent quality with stable residual solids. These findings would be valuable in operating the wastewater treatment system for toxic waste removal.

Migration settlement networks in the Carpathian Basin, 2001–2011

Looking at the relationship between the place of birth and current residential locations of foreign citizens arriving in Hungary from the neighbouring countries, in general, we establish that smaller migration distance involves migrants with a lower level of education, while preference for longer distances is determined by higher qualifications of migrants. The potential impact area of migrants grows in line with the education attainments of migrants. A scale-free settlement topology can be seen from the neighbouring countries of immigration to Hungary. This means that most of the settlements of Hungary have just a few links to settlements of neighbouring countries, from a migration point of view, while few Hungarian settlements have many connections. This finding also means that, instead of the national migration strategy, the subsidiary and the regional strategies can play a decisive role in the management of the international migration process
d0 Ferromagnetism in Oxide Nanowires: Role of Intrinsic Defects

In this report, we have investigated the origin of defect-induced room-temperature d 0 ferromagnetism in pure SnO2 and ZnO nanowires (NWs) with average diameter ~ 50 nm, prepared by template assisted route. Photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopic measurements show the singly ionized oxygen vacancy is inducing ferromagnetism in pure SnO2 NWs whereas cation (Zn) vacancy is found to responsible for the ferromagnetic behaviour in pure ZnO NWs. Besides, it is found that the Zn vacancy-induced ferromagnetism in ZnO can be tuned by substituting few percentage of nonmagnetic alkali metal like potassium (K) at Zn site. Saturation moment as well as Curie temperature has found to increase significantly with K-doping up to 4 at. % but a decrease of ferromagnetic response is observed for higher K-doping. X-ray photoelectron spectra show that K+1 ions substitute at Zn site and thus introduce hole through which a ferromagnetic interaction between Zn vacancies can be mediated. The direct correlation between the Zn vacancy concentration and the corresponding saturation moment indicates that Zn vacancyinduced ferromagnetism in ZnO can be successfully tuned by K-doping that can an exciting approach to prepare ZnO-based dilute magnetic semiconductors for modern spintronic technology.
J ul 2 01 9 Stochastic Closures for Wave – Current Interaction Dynamics

Wave–current interaction (WCI) dynamics energizes and mixes the ocean thermocline by producing a combination of Langmuir circulation, internal waves and turbulent shear flows, which interact over a wide range of time scales. Two complementary approaches exist for approximating different aspects of WCI dynamics. These are the Generalized Lagrangian Mean (GLM) approach and the Gent–McWilliams (GM) approach. Their complementarity is evident in their Kelvin circulation theorems. GLM introduces a wave pseudomomentum per unit mass into its Kelvin circulation integrand, while GM introduces a an additional ‘bolus velocity’ to transport its Kelvin circulation loop. The GLM approach models Eulerian momentum, while the GM approach models Lagrangian transport. In principle, both GLM and GM are based on the Euler–Boussinesq (EB) equations for an incompressible, stratified, rotating flow. The differences in their Kelvin theorems arise from differences in how they model the flow map in the Lagrangian for the Hamilton variational principle underlying the EB equations. A recently developed approach for uncertainty quantification in fluid dynamics constrains fluid variational principles to require that Lagrangian trajectories undergo Stochastic Advection by Lie Transport (SALT). Here we introduce stochastic closure strategies for quantifying uncertainty in WCI by adapting the SALT approach to both the GLM and GM approximations of the EB variational principle. In the GLM framework, we introduce a stochastic group velocity for transport of wave properties, relative to the frame of motion of the Lagrangian mean flow velocity and a stochastic pressure contribution from the fluctuating kinetic energy. In the GM framework we introduce a stochastic bolus velocity in addition to the mean drift velocity by imposing the SALT constraint in the GM variational principle.
Optimization and Performance Analysis of Spiro Helical Antenna Compared To Conventional Helix

Helical antennas are most preferable antennas for getting the high gain and circular polarization over a wide band width. But here in this thesis create some modification in helical antenna to reduce the size and improving the gain, axial ratio, band width and VSWR by using doubly helical geometry. Which provides mores more gain and circular polarization but occupies volume ratio 2.5 to 3 times smaller than conventional helix having about the same radiation characteristics? This novel antenna is called Spiro Helical antenna. Based on simulation and measurement results indicate that the Spiro Helical antenna indeed provide high gain and circular polarization over wide band width . finally the results are experimentally verified.
Title Feeding effect of selenium enriched rotifers on larval growth anddevelopment in red sea bream

18 19 Feeding trials were conducted to investigate the effect of selenium (Se)-enriched rotifers 20 on growth and development of red sea bream Pagrus major larvae. Fish were reared from 21 fertilized eggs (98% hatch rate) to 20 days post hatch (dph) at 19°C with two different food 22 sources; non-enriched S-type rotifers (0.0 μg Se/g D.W., control diet) or Se-enriched rotifers 23 (2.2 μg Se/g D.W., Se-enriched diet) at 10 rotifers/mL, respectively. On the last day of 24 larviculture, the Se-enriched diet accelerated growth and developmental stage of fish larvae. 25 The larvae fed Se-enriched rotifers were advanced in the following parameters compared to 26 those fed control diet: total length (6.06 vs 5.53 mm), standard length (5.74 vs 5.26 mm), 27 head length (1.46 vs 1.28 mm), eye diameter (0.57 vs 0.50 mm), the number of caudal fin 28 rays (5.8 vs 1.9), and the proportion of individuals undergoing notochord flexion (55 vs 3%). 29 Fish larvae of 20 dph showed higher Se concentration (9.5±0.2 μg/g DW) with the Se30 enriched diet than with the control diet (1.3±0.3 μg/g DW), but there was no significant 31 differences in the composition of polyunsaturated fatty acids which significantly affect larval 32 growth and development. Therefore, the feeding of Se enriched rotifers enhanced growth 33 and development of the red sea bream P. major larvae. 34 35
3 D-Integration und 3 D-Datenstrukturen – Eine Übersicht

Neuartige Technologien wie die 3D-Integration schaffen die Voraussetzung, auch in der heutigen Nano-Ära die Erwartungen des Moore’schen Gesetzes zu erfüllen. Das Hinzufügen der dritten Dimension in modernen 2DSchaltkreisen ermöglicht höhere Integrationsdichten, kürzere Verbindungsleitungen und den Aufbau heterogener Systeme in einer Baugruppe. Die Vorteile der 3D-Integration lassen sich jedoch nur nutzen, wenn Layoutdesigner und Werkzeugentwickler den raschen Fortschritt auf diesem Gebiet bewusst erkennen. Dieser Beitrag gibt zunächst einen Überblick über aktuelle 3D-Integrationstechnologien sowie zu 3D-Baugruppen und 3D-integrierten Schaltkreisen. Danach werden 3D-Datenstrukturen untersucht und verglichen, um Schlussfolgerungen über deren zukünftige Anwendbarkeit zu ziehen.
Collaborative business networks evaluation of technological tools for decision support making

Nowadays, companies are living great difficulties on managing their business due to constant and unpredictable economic market fluctuations. Recent changes in market trends (such as the constant demand for new products and services, mass customization and the drastic reduction of delivery time) lead companies to adopt strategies of creating partnerships with other companies as a way to respond effectively to such difficult economical times. Collaborative Networks’ concept born by the consequence of companies could no longer consider their internal business processes’ management as sufficient and tend to seek for a collaborative approach with other partners for their critical processes. Information technologies (ICT) assumed a major role acting as “enablers” of these kinds of networks, enhancing information sharing and business process integration. Several new trends concerning ICT architectures have been created to support collaborative networks requirements, but still doesn’t exist a common platform to reduce the needed integration effort on virtual organizations. This study aims to investigate the current technological solutions available in the market which enhances the management of companies’ business processes (specially, Collaborative Planning). Finally, the research work ends with the presentation of a conceptual model to answer to the constraints evaluated.
