description: A stability analysis is performed on high-order schemes formulated using the Flux Reconstruction (FR) approach. The one-dimensional advection model equation is used for the assessment of the stability region of these schemes when coupled with Runge-Kutta-type time-march procedures. Schemes are created using different numbers of internal points for each cell of the discrete domain, in such a way that a broad spectrum of spatial discretization orders can be analyzed. Multiple correction functions are employed so that well-known schemes, for instance the Discontinuous Galerkin (DG) and the Staggered-Grid schemes, may also be included in the study. The stability analysis is performed by identifying the behavior, in the complex plane, of the eigenvalues associated with each one of the considered cases. It is observed that, as the order of the scheme increases, a significant decrease in its domain of stability occurs, followed by a significant reduction in the amount of artificial dissipation that is introduced to the solution.

description: The flow properties at the leading edge of a flat plate represent a singularity to the Blasius laminar boundary layer equations; by applying the Lagrangian approach the leading edge velocity profiles of the laminar boundary layer over a flat plate are studied. Experimental observations as well as the theoretical analysis show an exact Gaussian distribution curve as the original starting profile of the laminar flow. Comparisons between the Blasius solution and the Gaussian curve solution are carried out providing a new insight into the physics of the laminar flow.

description: With the proliferation of social media, a growing number of users search for and join group activities in their daily life. This develops a need for the study on the group identification (GI) task, i.e., recommending groups to users. The major challenge in this task is how to predict users' preferences for groups based on not only previous group participation of users but also users' interests in items. Although recent developments in Graph Neural Networks (GNNs) accomplish embedding multiple types of objects in graph-based recommender systems, they, however, fail to address this GI problem comprehensively. In this paper, we propose a novel framework named Group Identification via Transitional Hypergraph Convolution with Graph Self-supervised Learning (GTGS). We devise a novel transitional hypergraph convolution layer to leverage users' preferences for items as prior knowledge when seeking their group preferences. To construct comprehensive user/group representations for GI task, we design the cross-view self-supervised learning to encourage the intrinsic consistency between item and group preferences for each user, and the group-based regularization to enhance the distinction among group embeddings. Experimental results on three benchmark datasets verify the superiority of GTGS. Additional detailed investigations are conducted to demonstrate the effectiveness of the proposed framework.

description: Excerpts: Soviet grain production as well as yield data are in terms of "bunker weight," i.e., the weight of the grain as it comes from the combines. Thus the grain contains varying amounts of moisture and foreign matter depending mainly on weather conditions during harvesting. In analyzing Soviet grain utilization, it is desirable to be able to estimate the variation from year to year in the amount of moisture and foreign matter in the grain and to reflect this variation in the amount of grain included under "waste" in the grain utilization tables. The variation from average in the actual amount of precipitation received during the peak period in small grain harvesting is the main factor determining the moisture and foreign matter content of the grain. This conclusion was reached after considerable experimentation using various weather factors either singularly or in combination.

Uniform asymptotic approximation of diffusion to a small target: generalized reaction models

description: The diffusion of a reactant to a binding target plays a key role in many biological processes. The reaction-radius at which the reactant and target may interact is often a small parameter relative to the diameter of the domain in which the reactant diffuses. We develop uniform in time asymptotic expansions in the reaction-radius of the full solution to the corresponding diffusion equations for two separate reactant-target interaction mechanisms: the Doi or volume reactivity model, and the Smoluchowski-Collins-Kimball partial absorption surface reactivity model. In the former, the reactant and target react with a fixed probability per unit time when within a specified separation. In the latter, upon reaching a fixed separation, they probabilistically react or the reactant reflects away from the target. Expansions of the solution to each model are constructed by projecting out the contribution of the first eigenvalue and eigenfunction to the solution of the diffusion equation, and then developing matched asymptotic expansions in Laplace-transform space. Our approach offers an equivalent, but alternative, method to the pseudo-potential approach we previously employed in [Isaacson and Newby 2013] for the simpler Smoluchowski pure absorption reaction mechanism. We find that the resulting asymptotic expansions of the diffusion equation solutions are identical with the exception of one parameter: the diffusion limited reaction rates of the Doi and partial absorption models. This demonstrates that for biological systems in which the reaction-radius is a small parameter, properly calibrated Doi and partial absorption models may be functionally equivalent.

description: Using language models (LMs) pre-trained in a self-supervised setting on large corpora and then fine-tuning for a downstream task has helped to deal with the problem of limited label data for supervised learning tasks such as Named Entity Recognition (NER). Recent research in biomedical language processing has offered a number of biomedical LMs pre-trained using different methods and techniques that advance results on many BioNLP tasks, including NER. However, there is still a lack of a comprehensive comparison of pre-training approaches that would work more optimally in the biomedical domain. This paper aims to investigate different pre-training methods, such as pre-training the biomedical LM from scratch and pre-training it in a continued fashion. We compare existing methods with our proposed pre-training method of initializing weights for new tokens by distilling existing weights from the BERT model inside the context where the tokens were found. The method helps to speed up the pre-training stage and improve performance on NER. In addition, we compare how masking rate, corruption strategy, and masking strategies impact the performance of the biomedical LM. Finally, using the insights from our experiments, we introduce a new biomedical LM (BIOptimus), which is pre-trained using Curriculum Learning (CL) and contextualized weight distillation method. Our model sets new states of the art on several biomedical Named Entity Recognition (NER) tasks. We release our code and all pre-trained models

description: We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbiting near the stability limit of binary stars. Unlike the previous discoveries, the planet revolving around the eclipsing binary system Kepler-1647 has a very long orbital period (~1100 days) and was at conjunction only twice during the Kepler mission lifetime. Due to the singular configuration of the system, Kepler-1647b is not only the longest-period transiting CBP at the time of writing, but also one of the longest-period transiting planets. With a radius of 1.06+/-0.01 RJup it is also the largest CBP to date. The planet produced three transits in the light-curve of Kepler-1647 (one of them during an eclipse, creating a syzygy) and measurably perturbed the times of the stellar eclipses, allowing us to measure its mass to be 1.52+/-0.65 MJup. The planet revolves around an 11-day period eclipsing binary consisting of two Solar-mass stars on a slightly inclined, mildly eccentric (e_bin = 0.16), spin-synchronized orbit. Despite having an orbital period three times longer than Earth's, Kepler-1647b is in the conservative habitable zone of the binary star throughout its orbit.

description: Abstract
Non-alcoholic fatty liver disease (NAFLD) is a significant public health issue, and its frequency has risen in recent years. NAFLD refers to a group of disorders characterized by a buildup of fat in the liver. It is most commonly found in those who are overweight or obese. This thesis will use the distribution of genetic polymorphisms within NAFLD and control populations to answer a number of questions, including whether SNPs associated with a change in function of associated genes could perform natural experiments on disease progression, the role of environmental cofactors, the efficacy of therapeutic targets, and disease association mechanisms. This thesis also aims to identify the association between NAFLD risk and CVD risk in Scottish populations.

Using the GODARTs Scottish cohort (longitudinal). In GoDARTs, genotypic and biochemistry data were available for 13,150 patients.

We evaluated the role of the CYP2E1 gene, as well as biochemical and anthropometric parameters for their association with NAFLD in the GODARTs cohort. We found some candidate genes for CYP2E1, and environmental factors predispose to non-alcoholic fatty liver disease. In addition, we found the CYP2E1 polymorphism rs2249695 was positively associated with ALD. In IL-6 and IL-6R polymorphisms to interact with NAFLD in determining CVD risk, we did not find an association between them in the GODARTs cohort.

The work presented in this thesis highlights the worth of employing a large population dataset to investigate the distribution of genetic polymorphisms in NAFLD and control populations, as well as the relevance of environmental co-factors, therapeutic efficacy, and mechanisms of disease association.

description: This article reports the study of SnO by using the first-principles pseudopotential plane-wave method within the generalized gradient approximation (GGA). We have calculated the structural, elastic, electronic and optical of SnO under high pressure. The elastic properties such as the elastic constants Cij bulk modulus, shear modulus, Young modulus, anisotropic factor, Pugh ratio, Poisson ratio are calculated and analyzed. Mechanical stability of SnO at all pressure are confirmed by using Born stability criteria in terms of elastic constants and are associated with ductile behaviour based on G/B ratios. It is also found that SnO exhibits very high anisotropy. The energy band structure and density of states are also calculated and analyzed. The results show the semiconducting and metallic properties at 0 (zero) and high pressure, respectively. Furthermore, the optical properties such as dielectric function, refractive index, photoconductivity, absorption coefficients, loss function and reflectivity are also calculated. All the results are compared with those of the SnO where available but most of the results at high pressure are not compared due to unavailability of the results.

description: We explore a model based on the classically-scale invariant standard model (SM) with a strongly coupled vector-like dynamics, which is called hypercolor (HC). The scale symmetry is dynamically broken by the vector-like condensation at the TeV scale, so that the SM Higgs acquires the negative mass-squared by the bosonic seesaw mechanism to realize the electroweak symmetry breaking. An elementary pseudoscalar $S$ is introduced to give masses for the composite Nambu-Goldstone bosons (HC pions): the HC pion can be a good target to explore through a diphoton channel at the LHC. As the consequence of the bosonic seesaw, the fluctuating mode of $S$, which we call $s$, develops tiny couplings to the SM particles and is predicted to be very light. The $s$ predominantly decays to diphoton and can behave as an invisible axion-like dark matter. The mass of the $s$-dark matter is constrained by currently available cosmological and astrophysical limits to be $10^{-4} {\rm eV} \lesssim m_s \lesssim 1 \,{\rm eV}$. We find that the sufficient amount of relic abundance for the $s$-dark matter can be accumulated via the coherent oscillation. The detection potential in microwave cavity experiments is also addressed.

description: A fall is an abnormal activity that occurs rarely; however, missing to identify falls can have serious health and safety implications on an individual. Due to the rarity of occurrence of falls, there may be insufficient or no training data available for them. Therefore, standard supervised machine learning methods may not be directly applied to handle this problem. In this paper, we present a taxonomy for the study of fall detection from the perspective of availability of fall data. The proposed taxonomy is independent of the type of sensors used and specific feature extraction/selection methods. The taxonomy identifies different categories of classification methods for the study of fall detection based on the availability of their data during training the classifiers. Then, we present a comprehensive literature review within those categories and identify the approach of treating a fall as an abnormal activity to be a plausible research direction. We conclude our paper by discussing several open research problems in the field and pointers for future research.

description: Analysis of the correlation between the angular positions of distant radio galaxies on the sky and the orientations of their polarization vectors with respect to their major axes, indicates a dipolar anisotropy in the large scale. We consider a single mode of large-scale scalar perturbation to the FRW metric. Using Newman-Penrose formalism, we calculate the rotation of the galaxy major axis with respect to the polarization vector as the elliptic image and the polarization vector are carried through the perturbed space-time. The dependence of the rotation on the polar angular coordinate of the galaxy, is qualitatively similar to the claimed dipole pattern.

How to infer non-Abelian statistics and topological invariants from tunneling conductance properties of realistic Majorana nanowires

description: We consider a simple conceptual question with respect to Majorana zero modes in semiconductor nanowires: Can the measured non-ideal values of the zero-bias-conductance-peak in the tunneling experiments be used as a characteristic to predict the underlying topological nature of the proximity induced nanowire superconductivity? In particular, we define and calculate the topological visibility, which is a variation of the topological invariant associated with the scattering matrix of the system as well as the zero-bias-conductance-peak heights in the tunneling measurements, in the presence of dissipative broadening, using realistic nanowire parameters to connect the topological invariants with the zero bias tunneling conductance values. This dissipative broadening is present in both (the existing) tunneling measurements and also (any future) braiding experiments as an inevitable consequence of a finite braiding time. The connection between the topological visibility and the conductance allows us to obtain the visibility of realistic braiding experiments in nanowires, and to conclude that the current experimentally accessible systems with non-ideal zero bias conductance peaks may indeed manifest (with rather low visibility) non-Abelian statistics for the Majorana zero modes. In general, we find that large (small) superconducting gap (Majorana peak splitting) is essential for the manifestation of the non-Abelian braiding statistics, and in particular, a zero bias conductance value of around half the ideal quantized Majorana value should be sufficient for the manifestation of non-Abelian statistics in experimental nanowires.

description: The description of interacting quantum impurity models in steady-state nonequilibrium is an open challenge for computational many-particle methods: the numerical requirement of using a finite number of lead levels and the physical requirement of describing a truly open quantum system are seemingly incompatible. One possibility to bridge this gap is the use of Lindblad-driven discretized leads (LDDL): one couples auxiliary continuous reservoirs to the discretized lead levels and represents these additional reservoirs by Lindblad terms in the Liouville equation. For quadratic models governed by Lindbladian dynamics, we present an elementary approach for obtaining correlation functions analytically. In a second part, we use this approach to explicitly discuss the conditions under which the continuum limit of the LDDL approach recovers the correct representation of thermal reservoirs. As an analytically solvable example, the nonequilibrium resonant level model is studied in greater detail. Lastly, we present ideas towards a numerical evaluation of the suggested Lindblad equation for interacting impurities based on matrix product states. In particular, we present a reformulation of the Lindblad equation, which has the useful property that the leads can be mapped onto a chain where both the Hamiltonian dynamics and the Lindblad driving are local at the same time. Moreover, we discuss the possibility to combine the Lindblad approach with a logarithmic discretization needed for the exploration of exponentially small energy scales.

description: Excerpts from the report Introduction: This bulletin presents cereal statistics developed to provide a comparable long-term series of data for use by researchers, administrators, exporters, and others interested in the world grain supply. A four-part table is included for each of 117 countries, the world, and 10 major geographic regions of the world. Each table consists of grain area, yield, production, and production per person and includes, where applicable, wheat, rye, rice, corn, barley, oats, millet, sorghums, and other grains (mainly buckwheat and mixed grains). Regional and world totals are limited to those countries included in the publication. The country names used in the report do not imply any legal or constitutional status of territory or title. They are used to identify certain geographic land areas without any limitations to administrative or legal boundaries. Statistics used are primarily those published by the governments of each country. Other sources of statistics and information were used when published data from official governmental sources were not available. A major secondary source of statistics was provided through agricultural attaches of the U.S. Department of Agriculture and economic counselors of the U.S. Department of State assigned to U.S. embassies and consulates in foreign countries. Cereal statistics published by the Food and Agricultural Organization (FAO) of the United Nations in conjunction with published and unpublished data from other international organizations were used to fill some gaps. Where no data were available in some years for a few countries, estimates were made to complete the 26 year series.

Dialogical Narrative analysis on Islam in British Muslim Women's stories of Domestic Abuse

description: Domestic abuse is a human rights issue that has negative consequences for both individuals and wider society, including the cost to the economy and its impact on physical and mental health. Although numerous studies have been conducted on domestic abuse, there remains a dearth of academic literature focusing on the stories of Muslim women living in the UK. Furthermore, Muslims living in the West face inequalities, discrimination, and Islamophobia, all of which are likely to impact domestic abuse survivors. To explore how narratives on Islam are used to construct stories of domestic abuse, semi-structured interviews were conducted with five British Muslim women of South Asian descent. A dialogical narrative analysis underpinned by a social constructionist framework was employed to analyse the qualitative data. The findings highlight the way participants constructed narratives on ‘real Islam’ and ‘cultural Islam’, whereby the former is the antithesis to domestic abuse, while most participants perceived ‘cultural Islam’ and the concept of ‘honour’ and shame as explanations for their partners’ abuse. Narratives on Islam, as an instrument of abuse as well as a coping strategy, support previous research on this topic. Moreover, the findings illustrate how participants constructed counter- narratives on Islamophobia. A critical evaluation of the study is also presented, followed by a consideration of the implications for clinical practice, service providers, the field of counselling psychology, and further research.
Critical temperature of two-dimensional hydrogenated multilayer graphene-based diluted ferromagnet

description: In the paper a theoretical study of critical (Curie) temperature of diluted ferromagnet based on multilayer graphene (or graphite) with hydrogen adatoms deposited over carbon atoms belonging to single sublattice is presented. The calculations are performed within Pair Approximation (PA) for diluted ferromagnetic system with long-range interactions. The method is able to take into account the spin-space anisotropy of coupling. The results obtained within Mean Field Approximation (MFA) are also presented for comparison. The assumed interaction between hydrogen adatom spins is inversely proportional to their mutual distance, with the additional exponential attenuation reflecting the presence of disorder in the system. The results obtained for a wide range of impurity concentrations and interaction decay length are discussed. The strongly non-linear behaviour of critical temperature as a function of dilution is predicted, at variance with MFA predictions. Moreover, MFA tends to overestimate heavily the critical temperature values compared to PA. An universal dependence of critical temperature on impurity concentration and interaction decay length is found for strong dilution regime.

Star-shaped Oscillations of Leidenfrost Drops

description: We experimentally investigate the self-sustained, star-shaped oscillations of Leidenfrost drops. The drops levitate on a cushion of evaporated vapor over a heated, curved surface. We observe modes with $n = 2-13$ lobes around the drop periphery. We find that the wavelength of the oscillations depends only on the capillary length of the liquid, and is independent of the drop radius and substrate temperature. However, the number of observed modes depends sensitively on the liquid viscosity. The dominant frequency of pressure variations in the vapor layer is approximately twice the drop oscillation frequency, consistent with a parametric forcing mechanism. Our results show that the star-shaped oscillations are driven by capillary waves of a characteristic wavelength beneath the drop, and that the waves are generated by a large shear stress at the liquid-vapor interface.
