RADIO-LOUD ACTIVE GALACTIC NUCLEUS: IS THERE A LINK BETWEEN LUMINOSITY AND CLUSTER ENVIRONMENT?

We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project, characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z ∼ 0.5 that covers three decades of radio luminosity. This is the first systematic X-ray environmental study at a single epoch, and has allowed us to examine the relationship between radio luminosity and cluster environment without the problems of Malmquist bias. We have found a weak correlation between radio luminosity and host cluster X-ray luminosity, as well as tentative evidence that this correlation is driven by the subpopulation of low-excitation radio galaxies, with high-excitation radio galaxies showing no significant correlation. The considerable scatter in the environments may be indicative of complex relationships not currently included in feedback models.
Investigation of nanoporous material under quasi-equilibrium conditions

Based on the three parametric Lorenz system, a model was developed that permits to describe the behavior of the plasma-condensate system near phase equilibrium in a self-consistent way. Considering the effect of fluctuations of the growth surface temperature, the evolution equation and the corresponding Fokker-Planck equation were obtained. The phase diagram is built which determines the system parameters corresponding to the regime of the porous structure formation.
IS CAPM AN EFFICIENT MODEL? ADVANCED VERSUS EMERGING MARKETS

CAPM is one of the financial models most widely used by the investors all over the world for analyzing the correlation between risk and return, being considered a milestone in financial literature. However, in recently years it has been criticized for the unrealistic assumptions it is based on and for the fact that the expected returns it forecasts are wrong. The aim of this paper is to test statistically CAPM for a set of shares listed on New York Stock Exchange, Nasdaq, Warsaw Stock Exchange and Bucharest Stock Exchange (developed markets vs. emerging markets) and to compare the expected returns resulted from CAPM with the actually returns. Thereby, we intend to verify whether the model is verified for Central and Eastern Europe capital market, mostly dominated by Poland, and whether the Polish and Romanian stock market index may faithfully be represented as market portfolios. Moreover, we intend to make a comparison between the results for Poland and Romania. After carrying out the analysis, the results confirm that the CAPM is statistically verified for all three capital markets, but it fails to correctly forecast the expected returns. This means that the investors can take wrong investments, bringing large loses to them.
Basin evolution and destruction in an Early Proterozoic continental margin: the Rinkian fold–thrust belt of central West Greenland

In central West Greenland, early Palaeoproterozoic siliciclastic and carbonate sequences of the Karrat Group (shelf sequences of the Rae craton margin) were deposited in sedimentary basins controlled by NW- and SW-trending linked extensional fault systems. The shelf basins were later filled and overtopped by turbidite systems filling a foredeep advancing ahead of a thrust system – the Karrat Fjord thrust system – that propagated west to east. Deformation culminated in emplacement of basement-cored nappes, progressive deformation and high-grade metamorphism at c. 1.87 Ga. Reactivation of lower plate growth faults formed dome- and basin-like folds and related thrusts that refolded the structure of the Karrat Fjord thrust system and inverted the shelf basins. The southern Karrat Fjord thrust system was reworked in a belt of intense ductile NW-directed thrusting – the Nunaarsussuaq thrust system – formed at c. 1.84 Ga at the northern limit of the Nagssugtoqidian orogen. Kinematics of these events are at odds with the consensus view that the Rinkian fold–thrust belt is a northward extension of the Nagssugtoqidian orogen resulting from north–south convergence between the Rae and North Atlantic cratons. Application of structural restoration techniques to basin analysis of Palaeoproterozoic rocks has potential to provide new insights into Proterozoic orogenic processes worldwide.
Proximate mechanisms of colour variation in the frillneck lizard: geographical differences in pigment contents of an ornament

Animal coloration has evolved in contexts such as communication, camouflage, and thermoregulation. Most studies of animal coloration focus on its adaptive benefits, whereas its underlying mechanisms have received less attention despite their potential influence on adaptive benefits. In fish and reptiles, for example, colour variation from yellow to red can be produced by carotenoid and/or pteridine pigments, which differ dramatically in the way they are obtained (carotenoids through diet and pteridines synthesized de novo). Hence, potential adaptive benefits could differ greatly depending on the relative contribution to coloration of different pigments. In the present study, we investigate the mechanisms underlying colour variation in the frill of the Australian frillneck lizard (Sauropsida: Chlamydosaurus kingii). Frill colour varies between populations across the species’ range (red, orange, yellow or white). We argue that this geographical variation results from different concentrations of carotenoids and pteridines in the frill. Frill carotenoid concentrations were lower in eastern populations (yellow and white forms), and pteridines were present only in the red and orange forms, thereby explaining their redder hues. The observed geographical variation in frill carotenoids suggests variation in carotenoid availability across the species’ range, which is backed up by the finding that plasma carotenoid concentrations were higher in the red (western) compared to the yellow (eastern) form. Although no correlations were found between individual colour measurements, frill pigments and plasma carotenoids, our results suggest that selective pressures vary across the species’ range and we speculate that predation pressures and/or intrasexual signalling context differ between forms. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, 00, 000–000.

Cluster Schools for Diverse Students’ Needs in Malaysia: A System View

This study aims to examine the role of the cluster schools in Malaysia in order to meet the diverse needs of students. It also seeks to identify the efforts that were initiated by the cluster schools in managing the sustainability of their niche areas to be in line with their students’ needs. Data was collected using interviews and documents analysis which are related to six cluster schools in Malaysia from different excellent clusters. The findings showed that the niche areas of each cluster schools were selected based on their students’ excellence in academic, curricular or personality areas. Thus, the niche area of each cluster school is different from the others. This indicates that the interest and propensity of students in cluster schools are tailored with the creation and selection of different niche areas for each school. In addition, the study also showed that the cluster schools have organized various programs and activities to accelerate their students’ excellence in their particular niche areas. There are also programs and activities which were initiated by the students at national as well as international levels. Results obtained from this study proved that the creation of cluster schools in Malaysia is not just to accelerate the organizational excellence per se, but also to focus on the needs of diverse students. This is also strengthened by the efforts of the schools to accelerate their students’ excellence in their particular niche areas.
Photocatalytical Properties and Theoretical Analysis of N, Cd-Codoped TiO2 Synthesized by Thermal Decomposition Method

N, Cd-codoped TiO2 have been synthesized by thermal decomposition method. The products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), UV-visible diffuse reflectance spectra (DRS), X-ray photoelectron spectroscopy (XPS), and Brunauer-Emmett-Teller (BET) specific surface area analysis, respectively. The products represented good performance in photocatalytic degradation of methyl orange. The effect of the incorporation of N and Cd on electronic structure and optical properties of TiO2 was studied by first-principle calculations on the basis of density functional theory (DFT). The impurity states, introduced by N 2p or Cd 5d, lied between the valence band and the conduction band. Due to dopants, the band gap of N, Cd-codoped TiO2 became narrow. The electronic transition from the valence band to conduction band became easy, which could account for the observed photocatalytic performance of N, Cd-codoped TiO2. The theoretical analysis might provide a probable reference for the experimentally element-doped TiO2 synthesis.
Motivating Learners and the Importance of Materials Used in Language Teaching

The motivation of the learner is one of the most important factors in Second Language Acquisition (SLA), meanwhile language teaching materials are having a very important effect and role in language learning and teaching activities. This research focus on how different materials motivate students. Many factors which affect student's motivation towards teaching materials were perceived, such as interest in the subject matter, level of difficulty, relevance to existing knowledge, perception of usefulness.
DESIGNING AN EQUALIZER STRUCTURE USING GRADIENT DESCENT ALGORITHMS

In recent years, a growing field of research in “Adaptive Systems” has resulted in a variety of adaptive automatons whose characteristics in limited ways resemble certain behaviors of living systems and biological adaptive processes. The essential and principal property of the adaptive systems is its time-varying, self-adjusting performance by using a process called “learning” from its environment. A channel equalizer is a very good example of an adaptive system, which has been considered in this work to assess its performance with reference to various novel learning algorithms developed. The two main threats for the digital communication systems are Inter-symbol Interference (ISI) and the presence of noise in the channels which are both time varying. So, for rapidly varying channel characteristics, the equalizer too need to be adaptive. In order to combat with such problems various adaptive equalizers have been proposed. Particularly, when the decision boundary is highly nonlinear, the classical equalizers (so called linear ones) do not perform satisfactorily. The use of Artificial Neural Networks (ANNs) provides the required nonlinear decision boundary. The Back Propagation (BP) algorithm revolutionized the use of ANNs in diverse fields of science and engineering. The main problem with this algorithm is its slow rate of convergence. But the high speed digital communication systems, in the presence of rapidly fading channels, demand for faster training. To overcome this problem a faster method of training the neural network using RLS algorithm is proposed in this thesis work. But both the BP and RLS based BP algorithms belong to the family of Gradient-based algorithms, which have the inherent problem of getting trapped in local minima. Since obtaining a global solution is the main criterion for any adaptive system, an efficient search technique is highly desirable. Tabu Search serves this purpose.
Carbon mineralization and carbonate preservation in modern cold-water coral reef sediments on the Norwegian shelf

Abstract. Cold-water coral ecosystems are considered hot-spots of biodiversity and biomass production and may be a regionally important contributor to carbonate production. The impact of these ecosystems on biogeochemical processes and carbonate preservation in associated sediments were studied at Rost Reef and Traenadjupet Reef, two modern (post-glacial) cold-water coral reefs on the Mid-Norwegian shelf. Sulfate and iron reduction as well as carbonate dissolution and precipitation were investigated by combining pore-water geochemical profiles, steady state modeling, as well as solid phase analyses and sulfate reduction rate measurements on gravity cores of up to 3.25 m length. Low extents of sulfate depletion and dissolved inorganic carbon (DIC) production, combined with sulfate reduction rates not exceeding 3 nmol S cm−3 d−1, suggested that overall anaerobic carbon mineralization in the sediments was low. These data showed that the coral fragment-bearing siliciclastic sediments were effectively decoupled from the productive pelagic ecosystem by the complex reef surface framework. Organic matter being mineralized by sulfate reduction was calculated to consist of 57% carbon bound in CH2O groups and 43% carbon in -CH2- groups. Methane concentrations were below 1 μM, and failed to support the hypothesis of a linkage between the distribution of cold-water coral reefs and the presence of hydrocarbon seepage. Reductive iron oxide dissolution linked to microbial sulfate reduction buffered the pore-water carbonate system and inhibited acid-driven coral skeleton dissolution. A large pool of reactive iron was available leading to the formation of iron sulfide minerals. Constant pore-water Ca2+, Mg2+ and Sr2+ concentrations in most cores and decreasing Ca2+ and Sr2+ concentrations with depth in core 23–18 GC indicated diagenetic carbonate precipitation. This was consistent with the excellent preservation of buried coral fragments.
Accelerating Fruchterman-Reingold with OpenCL

Twilight, an interactive multi-touch graph visualization research tool jointly developed by the University of Amsterdam and SURFsara, uses the Fruchterman-Reingold algorithm (amongst others) to create meaningful layouts for graphs. The required time for this algorithm to complete scales exponentially with the size of the graphs, therefore rendering large graphs quickly becomes impractical. To combat this an investigation was conducted into parallelizing this algorithm for use on Graphical Processing Units. This thesis describes the design and implementation of an OpenCL based implementation of the Fruchterman-Reingold algorithm. We show that this implementation speeds up the rendering of graphs by a factor of up to 15 times compared to the original implementation within Twilight.
Paying to Avoid Recession: Using Reenlistment to Estimate the Cost of Unemployment

This paper provides revealed preference estimates of the monetary value to workers of a lower unemployment rate at the time of job separation. By examining the decision between reenlisting and exiting the military, we find that service members would sacrifice 1.5–2 percent in earnings to avoid a 1 percentage point increase in the home-state unemployment rate during job search. Comparing these quantities to realized earnings losses for those who separate suggests that the value of nonwork time and other factors (e.g., private and public transfers) offset less than one-third of the earnings losses caused by exiting the military into a weak labor market.

Ocena skuteczności leczenia hipotensyjnego pacjentów z nadciśnieniem tętniczym i chorobą niedokrwienną serca lub ekwiwalentem wieńcowym

Introduction. Arterial hypertension (AH) is a well-known cardiovascular risk factor. Currently, in Poland, approximately 32% of adults suffer from AH, and only 26% of them are treated successfully. The study aims to determine the incidence of atherosclerosis risk factors and their influence on the effectiveness of hypotensive treatment in the population of patients with AH and coexisting coronary artery disease (CAD) or coronary equivalent. Material and methods. The study included 204 adults. The inclusion criteria were: diagnosis of AH with coexisting a diagnosis of CAD (138 people) or coronary equivalent defined as high (≥ 5%) atherosclerosis-related risk of death in 10-year prognosis, estimated using the EURO SCORE scale (66 people). During observation, pharmacological and nonpharmacological treatments were modified according to the current AH treating standards. After 6 months of observation, the effectiveness of AH control was assessed. Results. Multivariate logistic regression analysis revealed that main factors affecting poor blood pressure control after six months of observation were: obesity, age > 65 years, LDL cholesterol level > 130 mg/dL. Moreover, systolic blood pressure (SBP) < 140 mmHg was more frequent in patients with diabetes mellitus. After six months of therapy, good control of SBP was found in 42.7% of patients and normal values of diastolic blood pressure (DBP) — in 65.2 % of patients. Conclusion. Independent risk factors for poor control of blood pressure were: high level of LDL-cholesterol, age > 65 years and female sex. Paradoxically, diabetes was not a risk factor for poor control of hypertension. The introduction of combined hypotensive and lipid-lowering drugs should contribute to a better control of hypertension in Poland.
Altitudinal patterns in breeding bird species richness and density in relation to climate, habitat heterogeneity, and migration influence in South Korea

1 Altitudinal patterns in the population ecology of mountain bird species are useful for 2 predicting species occurrence and behavior. Numerous hypotheses about the complex 3 interactions among environmental factors have been proposed; however, these remain 4 controversial. This study investigated the causes of altitudinal patterns in breeding bird species 5 richness and density in relation to climate, habitat heterogeneity, and migration influence in 6 Jirisan National Park, South Korea. We conducted a field survey of 142 plots at altitudes 7 between 200 and 1400 m above mean sea level in the breeding season. A total of 2771 8 individuals from 53 breeding bird species were recorded. Altitudinal patterns of species richness 9 and density showed a hump-shaped pattern, indicating that the highest richness and density could 10 be observed at moderate altitudes. Models constructed with 16 combinations of six variables 11 demonstrated that species richness was positively correlated with vertical and horizontal habitat 12 heterogeneity, and that density was positively correlated with vertical, but not horizontal, habitat 13 heterogeneity, and negatively correlated with migrant rate. No significant relationships were 14 found between spring temperature and species richness or density. Therefore, the observed 15 patterns in species richness support the hypothesis that habitat heterogeneity, rather than climate, 16 is the main driver of species richness. And neither habitat heterogeneity nor climate hypotheses 17 fully explains the observed patterns in density. However, vertical habitat heterogeneity does 18 likely help explain observed patterns in density. The heterospecific attraction hypothesis did not 19 apply to the distribution of birds along the altitudinal gradient. Appropriate management of 20 vertical habitat heterogeneity, such as vegetation cover, should be maintained for the 21 conservation of bird diversity in this area. 22
Entrepreneurial Behavior During Industry Emergence: An Unconventional Study of Discovery and Creation in the Early PC Industry

Acting entrepreneurially in nascent industries is a complex endeavor characterized by uncertainty and ambiguity. Nevertheless, entirely new industries do emerge, often as a direct result of entrepreneurial behavior. We extend and apply discovery and creation approaches to study entrepreneurial behavior during industry emergence by means of qualitative analysis of a film about the personal computer (PC) industry℉s formative years. We find that discovery and creation behavior are fundamentally interrelated and share a common element: bricolage. Moreover, ideological activism is a major component of entrepreneurial behavior in a new industry℉s formative years during both creation and discovery processes. Implications for research and practice are discussed.
The AM Canum Venaticorum binary SDSS J173047.59+554518.5

The AM Canum Venaticorum (AM CVn) binaries are a rare group of hydrogen-deficient, ultrashort period, mass-transferring white dwarf binaries and are possible progenitors of Type Ia supernovae. We present time-resolved spectroscopy of the recently discovered AM CVn binary SDSS J173047.59+554518.5. The average spectrum shows strong double-peaked helium emission lines, as well as a variety of metal lines, including neon; this is the second detection of neon in an AM CVn binary, after the much brighter system GP Com. We detect no calcium in the accretion disc, a puzzling feature that has been noted in many of the longer period AM CVn binaries. We measure an orbital period, from the radial velocities of the emission lines, of 35.2 ± 0.2 min, confirming the ultracompact binary nature of the system. The emission lines seen in SDSS J1730 are very narrow, although double-peaked, implying a low-inclination, face-on accretion disc; using the measured velocities of the line peaks, we estimate i ≤ 11°. This low inclination makes SDSS J1730 an excellent system for the identification of emission lines.
Examining the Persuasive Potential of Web-based Health Behavior Change Support Systems

Understanding the persuasive potential of systems to support behavior change is increasingly important. If systems are not designed properly, their persuasive potential is not fulfilled. Previous research has shown that persuasive system design has a significant impact on adherence. Moreover, persuasive system features are likely to be advantageous in boosting effective user engagement with the technology and keeping the users motivated in their endeavors. In this study, we identify persuasive system features used in a selection of Web-based health behavior change support systems targeting excessive alcohol use and weight loss. We conducted en expert-based evaluation using the persuasive systems design model as a lens to view the twelve selected Web-based systems. The evaluation included a hands-on approach in which we used the systems for at least one month each and evaluated in terms of four categories: primary task support, computer-human dialogue support, system credibility, and social support. The results suggest that the systems harness a decent number of persuasive features. However, they had room for improvement (e.g., in terms of tailoring). Further research is needed to increase our understanding of how and under what conditions specific persuasive system features, either in isolation or collectively, lead to positive health outcomes in behavior change support systems across diverse contexts and populations. This study adds to the body of knowledge on designing persuasive health behavior change support systems.
Quantitative immunoprecipitation of GFP- fusion proteins using the GFP-Trap (PROT44)

Green fluorescent proteins (GFP) and derivates thereof are widely used to study protein localization and dynamics in living cells (Heim and Tsien, 1996; Tsien, 1998). The validation and interpretation of these data, however, requires additional information on biochemical properties of the investigated fluorescent fusion proteins e.g. enzymatic activity, DNA binding and interaction with other cellular components. For these biochemical analyses proteins are mostly fused with a small protein tag (e.g. Histidine-tag, c-Myc, FLAG or hemaglutinin). GFP, the most widely used labelling tag in cell biology is rarely used for biochemical analyses although various monoand polyclonal antibodies are available (Cristea et al., 2005) (Abcam, Cambridge, UK; Sigma, St. Louis, USA.; Roche, Mannheim, Germany).
