Simulations Of Galaxy Clusters With And Without Winds: I. The Structure Of Clusters

We use gas dynamic simulations to explore the effects of galactic winds on galaxy clusters. Two ensembles of 18 realizations, spanning a decade in temperature, are evolved with and without winds in an underlying biased CDM cosmology. Galaxies are identified as peaks in the initial density field, and are assumed to lose half their initial mass over a Hubble time in winds with an effective temperature of 8 keV. The energy input through winds boosts the entropy of the ICM above that generated by infall, resulting in a more extended density profile. The magnitude of this effect increases with decreasing mass or temperature, consistent with observations. The extended nature of the ICM with winds can lead to underestimates of the global baryon fraction, with low-temperature clusters particularly deficient. We calibrate the amplitude of this effect at density contrasts of 170 and 500. On the other hand, the final temperature of the gas is relatively unaffected; a similar mass-temperature relation exists with or without winds. The input wind energy is effectively consumed as work to lift the gas in the dark matter dominated potential. While the dark matter profile exhibits a self-similar form seen in other studies, the galaxy distribution is more centrally concentrated than either the dark matter or gas, and evidences a mild velocity bias. The gradient of galaxies with respect to primordial gas produces strong, negative radial gradients in metallicity within the ICM.
Low rank matrix recovery from few orthonormal basis measurements

Recent insights concerning the PhaseLift algorithm for retrieving phases have furthered our understanding of low rank matrix recovery from rank-one projective measurements. Motivated by the structure of certain quantum mechanical experiments, we introduce a particular class of such rank-one measurements: orthonormal basis measurements. One such measurement corresponds to choosing an orthonormal basis and treating all the rank-one projectors onto different basis elements as a series of consecutive measurement matrices. We elaborate on performing low-rank matrix recovery from few, sufficiently random orthonormal basis measurements and sketch applications of such a procedure in quantum physics. We conclude this article by presenting numerical experiments testing such an approach.
A review on inflammatory pain detection in human body through infrared image analysis

Temperature difference in the skin surface reflects the abnormality present in the human body. Considering the phenomenon, detection and forecasting the change of temperature is the principal objective of using Medical Infrared Thermography (MIT) as a diagnostic tool for inflammatory pain diseases. Medical Infrared Thermography (MIT) is a non-invasive, non-contact and fast imaging technique that record and monitor the flow of body temperature by receiving the infrared emitted from the skin surface. Based on the standardization of thermogram acquisition and processing techniques and by the adoption of advanced infrared cameras, presently it is feasible to detect the minor temperature difference of the skin surface in the high-resolution infrared images. Recently, the research on inflammatory pain detection using medical infrared thermography concentrated on the area of temperature and statistical analysis based automated detection of abnormality from the thermograms. The paper introduces a significant review focusing on the area of different inflammatory pain detection using infrared thermography along with the environmental condition, protocol selection, and acquisition system specification in summarized tabular format. Based on the rigorous study of the publications in the area of inflammatory pain thermography, the paper also explores the area of thermogram processing and analysis of pain in a review work format.

Graphical Abstract Highlights d One-third of coding genes significantly impact yeast biosynthetic metabolism d The amino acid metabolome is most sensitive to chromatin and transport proteins d TORC1 affects biosynthetic amino acid metabolism via vesicle-mediated transport d Metabolic signatures are gene specific and cluster 3,923 genes according to function In Brief The metabolome of a yeast gene deletion collection connects metabolism to gene function. SUMMARY Genome-metabolism interactions enable cell growth. To probe the extent of these interactions and delin-eate their functional contributions, we quantified the Saccharomyces amino acid metabolome and its response to systematic gene deletion. Over one-third of coding genes, in particular those important for chromatin dynamics, translation, and transport , contribute to biosynthetic metabolism. Specific amino acid signatures characterize genes of similar function. This enabled us to exploit functional metab-olomics to connect metabolic regulators to their ef-fectors, as exemplified by TORC1, whose inhibition in exponentially growing cells is shown to match an interruption in endomembrane transport. Providing orthogonal information compared to physical and genetic interaction networks, metabolomic signatures cluster more than half of the so far uncharacterized yeast genes and provide functional annotation for them. A major part of coding genes is therefore participating in gene-metabolism interactions that expose the metabolism regulatory network and enable access to an underexplored space in gene function.
Use of ontology-based ethnographic decision tree model to explore MMORPGs

As the internet has become increasingly accessible, an online gaming culture has evolved. The growth of online gaming reflects its importance to the gaming industry. Based on a sample of 46 college students, we formulated an ontology-based ethnographic decision tree model (OBEDTM) to predict whether these students will play massively multiplayer online games (MMORPGs). In this study, we applied the model to 180 additional students to test the predictive power of the OBEDTM. Results show that the OBEDTM has a predictive power of 97%, much better than that of the traditional model. In addition, the OBEDTM is more objective, cost efficient, and practical. Our study shows that college students do not play MMORPGs because they do not find them fulfilling. The main reason students choose to play MMORPGs is due to a friend's recommendation.
Clonal strains of Pseudomonas aeruginosa in paediatric and adult cystic fibrosis units

Despite recent reports of clonal strains of Pseudomonas aeruginosa in cystic fibrosis (CF) units, the need for routine microbiological surveillance remains contentious. Sputum was collected prospectively from productive patients attending the regional paediatric and adult CF units in Brisbane, Australia. All P. aeruginosa isolates were typed using pulsed-field gel electrophoresis. Spirometry, anthropometrics, hospitalisations and antibiotic sensitivity data were recorded. The first 100 sputum samples (first 50 patients at each clinic) harboured 163 isolates of P. aeruginosa. A total of 39 patients shared a common strain (pulsotype 2), 20 patients shared a strain with at least one other patient and 41 patients harboured unique strains. Eight patients shared a strain identical to a previously reported Australian transmissible strain (pulsotype 1). Compared with the unique strain group, patients harbouring pulsotype 2 were younger and had poorer lung function. Treatment requirements were similar in these two groups, as were the rates of multiresistance. In conclusion, 59% of patients harboured a clonal strain, supporting the need for routine microbiological surveillance. In contrast to previously described clonal strains, the dominant pulsotype was indistinguishable from nonclonal strains with respect to both colonial morphology and multiresistance. The clinical significance of clonal strains remains uncertain and requires longitudinal study.
Atmospheric Chemistry and Physics Simulating Atmospheric Composition over a South-east Asian Tropical Rainforest: Performance of a Chemistry Box Model T. A. M. Pugh Et Al.: Simulating Atmospheric Composition over a Tropical Rainforest

Atmospheric composition and chemistry above tropical rainforests is currently not well established, particularly for southeast Asia. In order to examine our understanding of chemical processes in this region, the performance of a box model of atmospheric boundary layer chemistry is tested against measurements made at the top of the rainforest canopy near Danum Valley, Malaysian Borneo. Multi-variate optimisation against ambient concentration measurements was used to estimate average canopy-scale emissions for isoprene, total monoterpenes and nitric oxide. The excellent agreement between estimated values and measured fluxes of isoprene and total monoterpenes provides confidence in the overall modelling strategy, and suggests that this method may be applied where measured fluxes are not available , assuming that the local chemistry and mixing are adequately understood. The largest contributors to the optimisa-tion cost function at the point of best-fit are OH (29%), NO (22%) and total peroxy radicals (27%). Several factors affect the modelled VOC chemistry. In particular concentrations of methacrolein (MACR) and methyl-vinyl ketone (MVK) are substantially overestimated, and the hydroxyl radical (OH) concentration is substantially underestimated; as has been seen before in tropical rainforest studies. It is shown that inclusion of dry deposition of MACR and MVK and wet depo-sition of species with high Henry's Law values substantially improves the fit of these oxidised species, whilst also substantially decreasing the OH sink. Increasing OH production arbitrarily, through a simple OH recycling mechanism , adversely affects the model fit for volatile organic compounds (VOCs). Given the constraints on isoprene flux provided by measurements, a substantial decrease in the rate of reaction of VOCs with OH is the only remaining option to explain the measurement/model discrepancy for OH. A reduction in the isoprene+OH rate constant of 50%, in conjunction with increased deposition of intermediates and some modest OH recycling, is able to produce both isoprene and OH concentrations within error of those measured. Whilst we cannot rule out an important role for missing chemistry, particularly in areas of higher isoprene flux, this study demonstrates that the inadequacies apparent in box and global model studies of tropical VOC chemistry may be more strongly influenced by representation of detailed physical and micrometeorological effects than errors in the chemical scheme.
VOLTAGE-ORIENTED CONTROL OF A GRID CONNECTED PV SYSTEM BY MODIFIED MPPT ALGORITHM

The output power of PV module varies with module temperature, solar irradiation and loads. And in order to quickly and accurately track the sun, it is necessary to track the maximum power point (MPP) all the time. An improved maximum power point tracking (MPPT) with better performance based on voltageoriented control (VOC) is proposed to solve a fast changing irradiation problem. In VOC, a cascaded control structure with an outer dc link voltage control loop and an inner current control loop is used. The MPPT controller is applied to the reference of the outer loop control dc voltage photovoltaic (PV). In this project, the main component of the single-stage grid connected PV system is the three-phase voltage source inverter (VSI). The voltage-oriented control (VOC) method used for VSI employs an outer dc link voltage control loop and an inner current control loop to achieve fast dynamic response. The performance of the power flow dependslargely on the quality of the applied current control strategy. In this project, the current control has beenimplemented in a rotating synchronous reference frame d, q because the controller can eliminate a steady-state error and has fast transient response by decoupling control. The robust tracking capability under rapidly increasing and decreasing irradiance is verified in simulations. Simulation results on a large-scale grid- connected PV system show the effectiveness of the proposed control scheme in terms of delivering maximum power into the grid under variable conditions.Index Terms:- Fast-changing irradiation, maximum power point (MPP) tracking (MPPT), proportional-integral (PI) control, voltage-oriented control (VOC).
The Views and Opinions of School Principals and Teachers on Positive Education.

The purpose of this study is to assess the views and opinions of school principals and teachers on positive education. The sample of the study includes 8 school principals and 12 teachers who attend different public schools in Izmir, Turkey. Data is collected through semi-structured interview technique. Findings show that majority of the participants have no knowledge about positive education and positive psychology. Participants state that schools can increase students’ well-being, and both academic and well-being skills can be taught at schools. Finally, majority of the participants report that positive education is necessary for Turkish schools.
Steep clines within a highly permeable genome across a hybrid zone between two subspecies of the European rabbit

Maintenance of genetic distinction in the face of gene flow is an important aspect of the speciation process. Here, we provide a detailed spatial and genetic characterization of a hybrid zone between two subspecies of the European rabbit. We examined patterns of allele frequency change for 22 markers located on the autosomes, X‐chromosome, Y‐chromosome and mtDNA in 1078 individuals sampled across the hybrid zone. While some loci revealed extremely wide clines (w ≥ 300 km) relative to an estimated dispersal of 1.95–4.22 km/generation, others showed abrupt transitions (w ≈ 10 km), indicating localized genomic regions of strong selection against introgression. The subset of loci showing steep clines had largely coincident centers and stepped changes in allele frequency that did not co‐localize with any physical barrier or ecotone, suggesting that the rabbit hybrid zone is a tension zone. The steepest clines were for X‐ and Y‐chromosome markers. Our results are consistent with previous inference based on DNA sequence variation of individuals sampled in allopatry in suggesting that a large proportion of each genome has escaped the overall barrier to gene flow in the middle of the hybrid zone. These results imply an old history of hybridization and high effective gene flow and anticipate that isolation factors should often localize to small genomic regions.
The Effects of Negative Pressure by External Tissue Expansion Device on Epithelial Cell Proliferation, Neo-Vascularization and Hair Growth in a Porcine Model

While pre-treating a fat transplant recipient site with negative pressure has shown promise for increasing the fat survival rate, the underlying mechanisms have not been investigated, partly due to challenges related to immobilization of vacuum domes on large animal subjects. The aim of this study was to examine the effect of negative pressure treatment by External Tissue Expansion Device (ETED) on fat grating recipient sites in a porcine model. The ETED was designed to provide negative pressure on the dorsum of swine. Pressure treatment (-70 mmHg) was applied for 1 or 3 hours every other day for 10 and 20 treatments. The treated areas (3.5 cm in diameter) were harvested and examined for histological changes, vessel density, cell proliferation (Ki67) and growth factor expression (FGF-1, VEGF and PDGB-bb). The application of the ETED increased epidermis thickness even after 1-hour treatments repeated 10 times. The results of Ki67 analysis suggested that the increasing thickness was due to cell proliferation in the epidermis. There was a more than two-fold increase in the vessel density, indicating that the ETED promotes vascularization. Unexpectedly, the treatment also increased the number of hair follicles. Negative pressure provided by the ETED increases the thickness of epidermis section of tissue, cell proliferation and vessel density. The porcine model provides a better representation of the effect of the ETED on skin tissue compared to small animal models and provides an environment for studying the mechanisms underlying the clinical benefits of negative pressure treatment.
Multi-focus Image Fusion with Structure-Driven Adaptive Regions

Due to the limited length of depth in camera, sometimes it is hard to capture a scenario focusing on all objects. This problem can be solved by taking multiple images, focusing on different parts, and fusing them into one image. How to select the pixels, which lies in the focus depth, with higher clarity, is still open. In this paper, a multi-focus image fusion method with structure-driven adaptive regions is proposed. By making use of the shared self-similarity in images, adaptive regions are estimated and the charities in these regions are counted. Experimental results show that the proposed approach preserves images edges better than image fusion methods with fixed size regions and the compared multi-scale decomposition domain image fusion methods.
The effect of hip joint exercise using an elastic band on dynamic balance, agility and flexibility in healthy subjects: a randomized controlled trial

Objective: The purpose of this study was to examine the effects of hip joint exercise using an elastic band on dynamic balance, agility, and flexibility in healthy subjects. Design: Randomized controlled trial. Methods: Thirty-five subjects (between 19 and 23 years) were randomly allocated to two groups: hip flexion exercise (HFE) group (n=17) and the hip abduction exercise (HAE) group (n=18). The HFE group participated in flexion exercise of the hip joint using an elastic band for 50 minutes a day, three days a week for four weeks, while the HAE group participated in abduction exercises of the hip joint using an elastic band for the same period. Dynamic balance was measured using the timed up and go (TUG) test, agility was measured with the standing long jump, and flexibility was measured using the Schober’s test (5 cm, 10 cm). Results: The HFE group showed significant differences in the TUG test, standing long jump, and the Schober’s test (10 cm) after training ( p <0.05). The HAE group showed significant differences in the TUG test, standing long jump and the Schober’s test (5 cm, 10 cm) after training ( p <0.05). However, there was no significant difference between the HFE group and the HAE group. Conclusions: Flexion and abduction exercises of the hip joint using and elastic band increased dynamic balance, agility, and flexibility in healthy subjects. Additional research on hip joint exercises using an elastic band for improving dynamic balance, agility and flexibility are necessary.
INSRT { INterpreted Sentiment in Real Time

The INSRT project short for INterpreted Sentiment in Real Time performs sentiment polarity classi cation on German tweets in real time. Classi cation of sentiment polarity in social media has become an important tool for reputation monitoring and trend analysis. For INSRT, we monitor the list of currently trending topics provided by the Twitter microblogging service and classify the tweets concerning these topics into positive, negative or neutral sentiment polarity. An user-friendly web interface is provided to show monitoring results; that is, a list of trending topics, associated tweets and sentiment classi cation results.
Identifying Eyewitness News-worthy Events on Twitter

In this paper we present a ﬁlter for identifying posts from eyewitnesses to various event types on Twitter, including shootings, police activity, and protests. The ﬁlter combines sociolin-guistic markers and targeted language content with straightforward keywords and regular expressions to yield good accuracy in the returned tweets. Once a set of eyewitness posts in a given semantic context has been produced by the ﬁlter, eyewitness events can subsequently be identiﬁed by enriching the data with additional geolocation information and then applying a spatio-temporal clustering. By applying these steps we can extract a complete picture of the event as it occurs in real-time, sourced entirely from social media.

Health Care Use Patterns for Diarrhea in Children in Low-Income Periurban Communities of Karachi, Pakistan

Diarrhea causes 16% of all child deaths in Pakistan. We assessed patterns of healthcare use among caretakers of a randomly selected sample of 959 children ages 0–59 months in low-income periurban settlements of Karachi through a cross-sectional survey. A diarrheal episode was reported to have occurred in the previous 2 weeks among 298 (31.1%) children. Overall, 280 (80.3%) children sought care. Oral rehydration solution and zinc were used by 40.8% and 2%, respectively; 11% were admitted or received intravenous rehydration, and 29% sought care at health centers identified as sentinel centers for recruiting cases of diarrhea for a planned multicenter diarrheal etiology case-control study. Odds ratios for independent predictors of care-seeking behavior were lethargy, 4.14 (95% confidence interval = 1.45–11.77); fever, 2.67 (1.27–5.59); and stool frequency more than six per day, 2.29 (1.03–5.09). Perception of high cost of care and use of home antibiotics were associated with reduced care seeking: odds ratio = 0.28 (0.1–0.78) and 0.29 (0.11–0.82), respectively. There is a need for standardized, affordable, and accessible treatment of diarrhea as well as community education regarding appropriate care in areas with high diarrheal burden.
