description: We explore the minimal conditions for sustainable cooperation on a spatially distributed population of memoryless, unconditional strategies (cooperators and defectors) in presence of unbiased, non contingent mobility in the context of the Prisoner's Dilemma game. We find that cooperative behavior is not only possible but may even be enhanced by such an ``always-move'' rule, when compared with the strongly viscous (``never-move'') case. In addition, mobility also increases the capability of cooperation to emerge and invade a population of defectors, what may have a fundamental role in the problem of the onset of cooperation.

description: In this work we explore the evolution of magnetic fields inside strongly magnetized neutron stars in axisymmetry. We model numerically the coupled field evolution in the core and the crust. Our code models the Hall drift and Ohmic effects in the crust, the back-reaction on the field from magnetically-induced elastic deformation of the crust, the magnetic twist exchange between the crust and the core, and the drift of superconducting flux tubes inside the core. The correct hydromagnetic equilibrium is enforced in the core. We find that i) The Hall attractor found by Gourgouliatos and Cumming in the crust exists also for configurations when the B-field penetrates into the core. However, the evolution timescale for the core-penetrating fields is dramatically different than that of the fields confined to the crust. ii) The combination of Jones' flux tube drift and Ohmic dissipation in the crust can deplete the pulsar magnetic fields on the timescale of $150$ Myr if the crust is hot ($T\sim2\times10^8$ K), but acts on much slower timescales for cold neutron stars, such as recycled pulsars ($\sim 1.8 $ Gyr, depending on impurity levels). iii) The outward motion of superfluid vortices during the rapid spin-down of a young highly magnetized pulsar, can result in a partial expulsion of flux from the core when $B\lesssim 10^{13}$ G. However for $B\gtrsim2\times 10^{13}$ G, the combination of a stronger magnetic field and a longer spin period implies that the core field cannot be expelled.

description: Recently, numerical calculations of the magnetic field evolution in neutron stars demonstrated the possible existence of a Hall attractor, a stage at which the evolution of the field driven by the Hall cascade ends. The existence of such a stage in neutron star magnetic evolution is very important, and can be potentially probed by observations. Here we discuss three types of objects which could have reached this stage. First, we briefly describe the evolution of normal radio pulsars with ages about a few hundred thousand years. Then we analyse in more detail observations of RX J1856.5-3754, one of the Magnificent Seven, focusing on the surface temperature distribution and comparing model predictions with the temperature map inferred from X-ray observations. Finally, we discuss the necessity of the Hall attractor stage to explain the hypothetical existence of accreting magnetars. We conclude that at the moment there is no direct confirmation of the Hall attractor stage in known sources. However, more detailed observations in the near future can demonstrate existence (or absence) of this stage of the crustal magnetic field evolution.

description: LIM kinases (LIMKs) are a family of protein kinases involved in the regulation of actin dynamics. There are two isoforms of LIMKs i.e., LIMK1 and LIMK2. LIMK1 is expressed abundantly in neuronal tissues. LIMK1 plays an essential role in the degradation of dendritic spines, which are important for our higher brain functions, such as memory and learning. The inhibition of LIMK1 improves the size and density of dendritic spines and acts as a protective effect against Alzheimer's disease. In this study, we have adopted ligand-based drug design and molecular modelling methods to identify virtual hits. The pharmacophoric features of PF-00477736 were used to screen the Zinc15 compounds library. The identified hits were then passed through drug-likeliness and PAINS filters. Further, comprehensive docking and rigorous molecular dynamics simulation study afforded three virtual hits viz., ZINC504485634, ZINC16940431 and ZINC1091071. The hits showed a better docking score than the standard ligand, PF-00477736. The docking score was found to be –8.85, –7.50 and –7.68 kcal/mol. These hits exhibited optimal binding properties with the target in docking study, blood-brain barrier permeability, in silico pharmacokinetics and low predicted toxicity. Communicated by Ramaswamy H.

When the gauged group is semisimple we are able to present exact formulae for the dual conformal field theory, for all values of the level $k$. The results are then applied to non-abelian target space duality in string theory, showing that the standard formulae are quantum mechanically well defined in the low energy limit if the gauged group is semisimple.

description: The study of synchronization in biological systems is essential for the understanding of the rhythmic phenomena of living organisms at both molecular and cellular levels. In this paper, by using simple dynamical systems theory, we present a novel mechanism, named transient resetting, for the synchronization of uncoupled biological oscillators with stimuli. This mechanism not only can unify and extend many existing results on (deterministic and stochastic) stimulus-induced synchrony, but also may actually play an important role in biological rhythms. We argue that transient resetting is a possible mechanism for the synchronization in many biological organisms, which might also be further used in medical therapy of rhythmic disorders. Examples on the synchronization of neural and circadian oscillators are presented to verify our hypothesis.

description: We develop the general formalism for performing perturbative diagrammatic expansions in the lattice theory of quantum gravity. The results help establish a precise correspondence between continuum and lattice quantities, and should be a useful guide for non-perturbative studies of gravity. The Feynman rules for Regge's simplicial lattice formulation of gravity are then discussed in detail in two dimensions. As an application, the two-dimensional conformal anomaly due to a $D$-component scalar field is explicitly computed in perturbation theory.

description: Thermal instability driven by radiation pressure might be relevant for intrinsically bright accreting sources. The most promising candidate where this instability seems to be at work is one of the two known galactic superluminal sources, GRS 1915+105 (Belloni et al. 1997). In spite of being of relevance, this scenario has not yet been confirmed by proper time-dependent modelling. Non-linear time-dependent calculations performed by Szuszkiewicz and Miller (1998) show that thermally unstable discs undergo limit-cycle behaviour with successive evacuation and refilling of the central parts of the disc. This evolution is very similar to the one proposed by Belloni et al. (1997) in their phenomenological model. Further investigations are needed to confirm the thermal instability being operational in this source. First of all the spectra emitted from the disc during its evolution should be calculated and compared with observations. Here such spectra are computed assuming local blackbody emission from the best studied transonic disc model.

description: We discuss the local properties of weak solutions to the equation $-Δu + b\cdot\nabla u=0$. The corresponding theory is well-known in the case $b\in L_n$, where $n$ is the dimension of the space. Our main interest is focused on the case $b\in L_2$. In this case the structure assumption $\operatorname{div} b=0$ turns out to be crucial.

description: The RST model is augmented by the addition of a scalar field and a boundary term so that it is well-posed and local. Expressing the RST action in terms of the ADM formulation, the constraint structure can be analysed completely. It is shown that from the view point of local field theories, there exists a hidden dynamical field in the RST model. Thanks to the presence of this hidden dynamical field, we can reconstruct the closed algebra of the constraints which guarantee the general invariance of the RST action. The resulting stress tensors are recovered to be true tensor quantities. At the quantum level, the cancellation condition for the total central charge is reexamined. Finally, with the help of the hidden dynamical field, the fact that the semi-classical static solution of the RST model has two independent parameters (P,M), whereas for the classical CGHS model there is only one, can be explained.

description: Objective: The REVIDA study aimed to assess the evolution of major depression symptoms in South East Asian (SEA) patients treated with vortioxetine for major depression in real-world clinical practice. Methods: This non-interventional study was conducted from August 2016 to April 2017. A total of 138 patients (aged 18–65 years) with an active episode of major depression were recruited from Malaysia, Philippines, Singapore and Thailand. Vortioxetine was initiated on the first visit and patients were followed for 3 months. Depression severity was assessed using the PHQ-9 questionnaire (patient assessed) and CGI-S scale (physician assessed); cognitive function was assessed with the PDQ-D questionnaire; work productivity and activity impairment (WPAI) was assessed with the WPAI questionnaire. Results: At baseline, 89.9% of patients were moderately to severely depressed (PHQ-9 score ≥10). During the 3 month treatment period, mean ± SD PHQ-9 score decreased from 18.7 ± 5.7 to 5.0 ± 5.3, mean ± SD CGI-S score decreased from 4.4 ± 0.7 to 2.2 ± 1.1 and mean ± SD PDQ-D score decreased from 42.1 ± 18.8 to 13.4 ± 13.0. By Month 3, response and remission rates reached 80.8% and 59.0%, respectively. Work productivity loss decreased from 73.6% to 30.5%, while activity impairment decreased from 71.5% to 24.6%. Positive correlations were observed between PHQ-9, PDQ-D, and WPAI work productivity loss and activity impairment. By Month 3, 82.0% of patients were either not depressed or only mildly depressed (PHQ-9 score ≤9). Conclusion: In real-world clinical settings, vortioxetine was effective in reducing depression severity and improving cognitive function and work productivity in SEA patients with major depression.

description: We present the first double-lined orbital solution for the close binary in the GW Ori triple system. Using 12 epochs of infrared spectroscopy, we detected the lines of both stars in the inner pair, previously known as single-lined only. Our preliminary infrared orbital solution has an eccentricity of e = 0.21 +/- 0.10, a period of P = 241.15 +/- 0.72 days, and a mass ratio of q = 0.66 +/- 0.13. We find a larger semi-amplitude for the primary star, K1 = 6.57 +/- 1.00 km s^-1, with an infrared-only solution compared to K1 = 4.41 +/- 0.33 km s^-1 with optical data from the literature, likely the result of line blending and veiling in the optical. The component spectral types correspond to G3 and K0 stars, with vsini values of 43 km s^-1 and 50 km s^-1, respectively. We obtained a flux ratio of alpha = 0.58 +/- 0.14 in the H-band, allowing us to estimate individual masses of 3.2 and 2.7 M_sun for the primary and secondary, respectively, using evolutionary tracks. The tracks also yield a coeval age of 1 Myr for both components to within 1 sigma. GW Ori is surrounded by a circumbinary/circumtriple disk. A tertiary component has been detected in previous studies; however, we did not detect this component in our near-infrared spectra, probably the result of its relative faintness and blending in the absorption lines of these rapidly rotating stars. With these results, GW Ori joins the small number of classical T Tauri, double-lined spectroscopic binaries.

A Large Eddy Simulation of Turbulent Compressible Convection: Differential Rotation in the Solar Convection Zone

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: We present results of two simulations of the convection zone, obtained by solving the full hydrodynamic equations in a section of a spherical shell. The first simulation has cylindrical rotation contours (parallel to the rotation axis) and a strong meridional circulation, which traverses the entire depth. The second simulation has isorotation contours about mid-way between cylinders and cones, and a weak meridional circulation, concentrated in the uppermost part of the shell. We show that the solar differential rotation is directly related to a latitudinal entropy gradient, which pervades into the deep layers of the convection zone. We also offer an explanation of the angular velocity shear found at low latitudes near the top. A non-zero correlation between radial and zonal velocity fluctuations produces a significant Reynolds stress in that region. This constitutes a net transport of angular momentum inwards, which causes a slight modification of the overall structure of the differential rotation near the top. In essence, the {\it thermodynamics controls the dynamics through the Taylor-Proudman momentum balance}. The Reynolds stresses only become significant in the surface layers, where they generate a weak meridional circulation and an angular velocity `bump'.

description: A primary source of asymmetric information arises from banks’ uncertainty about borrowers’ Creditworthiness. This can generate two types of barriers to efficient credit allocation in the loan market: ad-verse selection in the likelihood of repayment and moral hazard in the riskiness of firms’ business decisions, also affecting repayment. This study investigated the consequences of asymmetric information on Islamic financial contracts in the Pakistani market for small and medium enterprise (SME) business lines of credit. Islamic bank’s main financial contracts were discuss the two of them which are Istisna and Murabah .The methods of’ T test’ was conducted to ascertain the difference in means of both forms of financing, whereas Multiple Regression Analysis using panel data to assess the relationship of critical variables with Disbursed amount, profit rate, spread, tenor. Data of three year i.e. from 2016 to2018 of 35 firms, with 105 number of observations having istisna and murabah contract, were taken. The results suggested that both the means of murabah and istisna financing are significantly different in major performance indicators, implicating companies that have taken these two financing have performed differently. Secondly, in most of the ratio that mattered like efficiency and profitability, murabah based financing have yielded more efficient results and better performed as compared to istisna.

description: We present the results of deep optical imaging of the radio/$γ$-ray pulsar PSR J2043+2740, obtained with the Large Binocular Telescope (LBT). With a characteristic age of 1.2 Myr, PSR J2043+2740 is one of the oldest (non recycled) pulsars detected in $γ$-rays, although with still a quite high rotational energy reservoir ($\dot{E}_{\rm rot} = 5.6 \times 10^{34}$ erg s$^{-1}$). The presumably close distance (a few hundred pc), suggested by the hydrogen column density ($N_{\rm H} \lesssim 3.6 \times 10^{20}$ cm$^{-2}$), would make it a viable target for deep optical observations, never attempted until now. We observed the pulsar with the Large Binocular Camera of the LBT. The only object (V=25.44$\pm$0.05) detected within ~3" from the pulsar radio coordinates is unrelated to it. PSR J2043+2740 is, thus, undetected down to V~26.6 (3-$σ$), the deepest limit on its optical emission. We discuss the implications of this result on the pulsar emission properties.

description: Association models like Cubic Plus Association (CPA) equation of state and other Statistical Associating Fluid Theory variants have found widespread use, especially over the recent 30 or so years, and this is not limited anymore to universities and researchers. Industry is beginning slowly to adopt such models for some applications and a few of the association models are now provided by commercial simulators. Association models account explicitly for hydrogen bonding (and other complex) phenomena, and for this reason, they are potentially more useful and more successful than traditional models like cubic equations of state and activity coefficient models. Still, for practical applications, all models are judged by their results and these depend on the availability of experimental data, the number and type of adjustable parameters and the performance of the models for phase equilibria and occasionally also for other properties. We will consider four case studies in this work which, will illustrate some of the capabilities and limitations of these association models in different applications. We will offer a ‘model developer’s’ point of view showing in several cases all stages of model development in order to illustrate what worked, what did not and how it was corrected (when possible). The ‘physics’ and ‘application’ aspects of the models will be in all cases discussed. All results will be shown with the CPA equation of state, although we expect that the overall conclusions will be the same for a wide range of association models.

description: The significance of zero modes in the path-integral quantization of some solitonic models is investigated. In particular a Skyrme-like theory with topological vortices in (1+2) dimensions is studied, and with a BRST invariant gauge fixing a well defined transition amplitude is obtained in the one loop approximation. We also present an alternative method which does not necessitate evoking the time-dependence in the functional integral, but is equivalent to the original one in dealing with the quantization in the background of the static classical solution of the non-linear field equations. The considerations given here are particularly useful in - but also limited to - the one-loop approximation.

description: Grid-control is a lightweight and highly portable open source submission tool that supports virtually all workflows in high energy physics (HEP). Since 2007 it has been used by a sizeable number of HEP analyses to process tasks that sometimes consist of up 100k jobs. grid-control is built around a powerful plugin and configuration system, that allows users to easily specify all aspects of the desired workflow. Job submission to a wide range of local or remote batch systems or grid middleware is supported. Tasks can be conveniently specified through the parameter space that will be processed, which can consist of any number of variables and data sources with complex dependencies on each other. Dataset information is processed through a configurable pipeline of dataset filters, partition plugins and partition filters. The partition plugins can take the number of files, size of the work units, metadata or combinations thereof into account. All changes to the input datasets or variables are propagated through the processing pipeline and can transparently trigger adjustments to the parameter space and the job submission. While the core functionality is completely experiment independent, integration with the CMS computing environment is provided by a small set of plugins.

description: Longitudinal studies of rapid disease progression often rely on noisy biomarkers; the underlying longitudinal process naturally varies between subjects and within an individual subject over time; the process can have substantial memory in the form of within-subject correlation. Cystic fibrosis lung disease progression is measured by changes in a lung function marker (FEV1), such as a prolonged drop in lung function, clinically termed rapid decline. Choosing a longitudinal model that estimates rapid decline can be challenging, requiring covariate specifications to assess drug effect while balancing choices of covariance functions. Two classes of longitudinal models have recently been proposed: segmented and stochastic linear mixed effects (LMEs) models. With segmented LMEs, random changepoints are used to estimate the timing and degree of rapid decline, treating these points as structural breaks in the underlying longitudinal process. In contrast, stochastic LMEs, such as random walks, are locally linear but use continuously changing slopes, viewing bouts of rapid decline as localized, sharp changes. We compare commonly used variants of these approaches through an application using the Cystic Fibrosis Foundation Patient Registry. Changepoint modeling had the worst fit and predictive accuracy but certain covariance forms in stochastic LMEs produced problematic variance estimates.
Computation of the Adjoint Matrix

description: The best method for computing the adjoint matrix of an order $n$ matrix in an arbitrary commutative ring requires $O(n^{β+1/3}\log n \log \log n)$ operations, provided the complexity of the algorithm for multiplying two matrices is $γn^β+o(n^β)$. For a commutative domain -- and under the same assumptions -- the complexity of the best method is ${6γn^β}/{(2^β-2)}+o(n^β)$. In the present work a new method is presented for the computation of the adjoint matrix in a commutative domain. Despite the fact that the number of operations required is now 1.5 times more, than that of the best method, this new method permits a better parallelization of the computational process and may be successfully employed for computations in parallel computational systems.

Subjects: Islamic Socialism, Islamic Capitalism, Capitalism, Islamic Socialistic Capitalism

description: This research takes insights into the research on Islamic finance before and after the occurrence of financial crisis to rediscover its linkages with Islamic socialism and capitalism across international boundaries to establish grounds of Islamic finance theoretical framework. It takes extensive review of literature on Islamic Socialism, Capitalism and Islamic Capitalism taking into account differences in practices of Islamic finance in Islamic and non Islamic countries. Research in Islamic finance has great linkages with Islamic socialism, Islamic capitalism and capitalism as affected by the occurrence of financial crisis during the period of research. The originality value of this research work lies in the novel selection of period of research literature, and the discovery of theoretical framework in Islamic finance research, “Islamic socialistic capitalism”.

description: The structure of societies has been changing with the rapid progress of science and
technology in the 21st century. In this new structuring era, education is the only valid
method to raise individuals who are able to make effective decisions, solve problems and take
responsibility for learning and thinking critically. For this reason, learning to think rationally
and critically are the keys to educational reforms in a number of educational settings
worldwide. In the literature about teaching critical thinking, teacher behaviors are regarded
as the most influential variables for the development of critical thinking among students.
However, teachers can implement instruction geared towards critical thinking only when they
develop a conception of critical thinking. This qualitative study, conducted with five EFL
teachers at a high school, aims at investigating in-service EFL teachers’ conceptualizations of
critical thinking as well as the strategies they use to infuse critical thinking into their EFL
courses. The findings indicate that participating teachers have adequate knowledge about
critical thinking and they incorporate certain techniques to cultivate critical thinking among
language learners. We recommend that there should be more focus on exploring critical
thinking conceptions and practice among EFL teachers working at different levels.
Radio-quiet quasar environments at 0.5 < z < 0.8

description: We have quantified the galaxy environments around a sample of 0.5 < z < 0.8 radio-quiet quasars using the amplitude of the spatial galaxy--quasar correlation function, B_gq. The quasars exist in a wide variety of environments, some sources are located in clusters as rich as Abell class 1--2 clusters, whereas others exist in environments comparable to the field. We find that on average, the quasars prefer poorer clusters of approximately Abell class 0, which suggests that quasars are biased tracers of mass compared to galaxies. The mean B_gq for the sample is found to be indistinguishable from the mean amplitude for a sample of radio-loud quasars matched in redshift and optical luminosity. These observations are consistent with recent studies of the hosts of radio-quiet quasars at low to intermediate redshifts, and suggest that the mechanism for the production of powerful radio jets in radio-loud quasars is controlled by processes deep within the active galactic nucleus itself, and is unrelated to the nature of the hosts or their environments.

description: Technology advanced has brought rapid changes in all human activities along with financial activities and tools. Digital currency one of the technological innovations which have taken significant focuses from consumers, investors, researchers, entrepreneurs and policy makers around the world. with the trend of changing patterns, Islamic finance is rapidly developing all over the world by serving Muslims and non-Muslims, as a result, it is mandatory for Islamic finance to adapt with modern technology systems in terms of providing innovative products and services to the consumers in line with shariah perspectives. As a result, cryptocurrency (digital currency) has taken the focus on Islamic scholars in regards of its permissibility. There are many arguments over the permissibility issues. Therefore, this study aims to explore those issues and mechanisms of cryptocurrency in order to evaluate with Islamic perspective. This study gathered secondary sources from past literatures, books, news and websites with qualitative approach. The findings inclined that there are still lacking in mechanisms of digital currency to comply with Islamic perspective such as real asset backed and legal authorization. The findings of this study will benefit the Islamic scholars and policy makers along with Muslim consumers and investors in regards of permissibility and developing existing cryptocurrency to widely use in the Islamic finance and banking sector.

description: Resource pooling in ad hoc networks deals with accumulating computing and network resources to implement network control schemes such as routing, congestion, traffic management, and so on. Pooling of resources can be accomplished using the distributed and dynamic nature of ad hoc networks to achieve collaboration between the devices. Ad hoc networks need a resource-pooling technique that offers quick response, adaptability, and reliability. In this context, we are proposing an opportunistic resource pooling scheme that uses a cognitive computing model to accumulate the resources with faster resource convergence rate, reliability, and lower latency. The proposed scheme is implemented using the behaviors observations beliefs cognitive model, in which the resource pooling decisions are made based on accumulated knowledge over various behaviors exhibited by nodes in ad hoc networks.

description: Created in 1987 to raise public awareness about the HIV/AIDS crisis, the NAMESProject unfurled the AIDS Memorial Quilt in over forty cities across the globe between 1987 and 1996. But for sixteen consecutive years, due to a rapid decline of public funding, it resided in storage, away from public view. Andrea Bowers’s photorealistic colored pencil drawing, Still Life of the AIDS Memorial Quilt in Storage (4336-4340) depicted the Quilt, not sprawled across public space, but in an Atlanta storage warehouse. In doing so, Bowers condemned the prolonged storage of the Quilt as a symptom of the public neglect toward the AIDS crisis in the 2000s. Furthermore, her original display of the drawing in the exhibition titled The Weight of Relevance in 2007 and 2008, was a self-reflexive commentary on the potential of art to serve as an activist tool. Rather than hang the drawing on a wall, she rested it on the floor and paired it with other works that memorialized the care and labor that art activism necessitates. The exhibition thus visualized that it is not the art object, but the community around it that matters. The success of Bowers’s work is testament to this fact. Although her Quilt-related drawings are currently unavailable for public view, in the wake of their exhibition, new medical treatments emerged and AIDS Memorial Quilt was digitized. Her work thus speaks to the social significance and political impact of art as activism.
