description: We report a comparative study of the series Fe1.1Te1-xSex and the stoichiometric FeTe1-xSex to bring out the difference in their magnetic, superconducting and electronic properties. The Fe1.1Te1-xSex series is found to be magnetic and its microscopic properties are elucidated through Moessbauer spectroscopy. The magnetic phase diagram of Fe1.1Te1-xSex is traced out and it shows the emergence of spin-glass state when the antiferromagnetic state is destabilized by the Se substitution. The isomer shift and quadrupolar splitting obtained from the Moessbauer spectroscopy clearly brings out the electronic differences in these two series.

ANODE MATERIAL

description: The development of high-performance electrode materials has become a critical area of research in the lithium and sodium-ion battery (LIBs and SIBs) community to meet the high energy and power density demands of the current and future electrical energy storage applications. So far, the progress in the development of suitable anode materials has been mostly limited to carbon-based materials, metal sulphides and oxides to a minor extent. Overall, these electrodes show room for improvement given their low voltage, low gravimetric density and poor long-term cyclability. Thus, at this juncture, alternative anodes to these with an excellent rate performance and a high capacity with long cyclability must be sought. The discovery of graphene initiated a surge of interest in other two-dimensional (2D) atomically thin materials, such as transition metal dichalcogenides (TMDs). These types of materials have been studied as promising materials for a broad range of applications for decades. The rising interest in these materials is due to their earth-abundant presence in nature, excellent mechanical properties, ability to tune interlayer spacing, good performance when large current densities are applied, long life capability and wide operation range temperatures. Although the excellent theoretical properties of these materials have not yet been reached, TMDs are a group of very promising materials to be used in energy storage. This thesis is a proof of concept to study the viability of two different TMD materials (WTe2 and TaTe2) as anode materials for both LIBs and SIBs. With this study, we will shed a light on the charge compensation mechanisms for these materials during lithium and sodium ion intercalation. The structure of the materials studied in this work was characterised using XRD, SEM and TEM. Their electrochemical response was tested using electrochemical techniques such as galvanostatic cycling, CV and EIS to probe ion (de)intercalation into the electrode crystal structure. Moreover, electrochemical tests were coupled with operando synchrotron XRD and XANES spectroscopy to understand the structural evolution upon ion insertion and extraction.

description: In this paper we consider the lossy compression of a binary symmetric source. We present a scheme that provides a low complexity lossy compressor with near optimal empirical performance. The proposed scheme is based on b-reduced ultra-sparse LDPC codes over GF(q). Encoding is performed by the Reinforced Belief Propagation algorithm, a variant of Belief Propagation. The computational complexity at the encoder is O(.n.q.log q), where is the average degree of the check nodes. For our code ensemble, decoding can be performed iteratively following the inverse steps of the leaf removal algorithm. For a sparse parity-check matrix the number of needed operations is O(n).

description: The problem of multi-agent learning and adaptation has attracted a great deal of attention in recent years. It has been suggested that the dynamics of multi agent learning can be studied using replicator equations from population biology. Most existing studies so far have been limited to discrete strategy spaces with a small number of available actions. In many cases, however, the choices available to agents are better characterized by continuous spectra. This paper suggests a generalization of the replicator framework that allows to study the adaptive dynamics of Q-learning agents with continuous strategy spaces. Instead of probability vectors, agents strategies are now characterized by probability measures over continuous variables. As a result, the ordinary differential equations for the discrete case are replaced by a system of coupled integral--differential replicator equations that describe the mutual evolution of individual agent strategies. We derive a set of functional equations describing the steady state of the replicator dynamics, examine their solutions for several two-player games, and confirm our analytical results using simulations.

description: The emergence of the metaverse is being widely viewed as a revolutionary technology owing to a myriad of factors, particularly the potential to increase the accessibility of learning for students with disabilities. However, not much is yet known about the views and expectations of disabled students in this regard. The fact that the metaverse is still in its nascent stage exemplifies the need for such timely discourse. To bridge this important gap, we conducted a series of semi-structured interviews with 56 university students with disabilities in the United States and Hong Kong to understand their views and expectations concerning the future of metaverse-driven education. We have distilled student expectations into five thematic categories, referred to as the REEPS framework: Recognition, Empowerment, Engagement, Privacy, and Safety. Additionally, we have summarized the main design considerations in eight concise points. This paper is aimed at helping technology developers and policymakers plan ahead of time and improving the experiences of students with disabilities.

description: We review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. Evidence from many different directions now all imply that five sixths of the material content of the universe is in this mysterious form, separate from and beyond the ordinary "baryonic" particles in the standard model of particle physics. Dark matter appears not to interact via the electromagnetic force, and therefore neither emits nor reflects light. However, it definitely does interact via gravity, and has played the most important role in shaping the Universe on large scales. The most successful technique with which to investigate it has so far been the effect of gravitational lensing. The curvature of space-time near any gravitating mass (including dark matter) deflects passing rays of light - observably shifting, distorting and magnifying the images of background galaxies. Measurements of such effects currently provide constraints on the mean density of dark matter, and its density relative to baryonic matter; the size and mass of individual dark matter particles; and its cross section under various fundamental forces.

Supersymmetric N=2 gauge theory with arbitrary gauge group

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A new universal model to implement the Seiberg-Witten approach to low-energy properties of the supersymmetric N=2 gauge theory with an arbitrary compact simple gauge group, classical or exceptional, is suggested. It is based on the hyperelliptic curve, whose genus equals the rank of the gauge group. The weak and strong coupling limits are reproduced. The magnetic and electric charges of light dyons, which are present in the proposed model comply with recent predictions derived from the general properties of the theory. The discrete chiral symmetry is implemented, the duality condition is reproduced, and connections between monodromies at weak and strong coupling are established. It is found that the spectra of monopoles and dyons are greatly simplified when vectors representing the scalar and dual fields in the Cartan algebra are aligned along the Weyl vector. This general feature of the theory is used for an additional verification of the model. The model predicts the identical analytic structures of the coupling constants for the theories based on the SU(r+1) and Sp(2r) gauge groups.

description: We compare the results of capacitance measurements in the lens-plane and sphere-plane configurations with theoretical predictions from various models of a spherical surface. It is shown that capacitance measurements are incapable of discriminating between models of perfect and modified spherical surfaces in an experiment demonstrating the anomalous scaling law for the electric force. Claims to the contrary in the recent literature are explained by the use of irregular comparison. The data from capacitance measurements in an experiment measuring the Casimir force using a micromechanical torsional oscillator are shown to be in excellent agreement with theoretical predictions using the model of a perfect spherical surface.

description: The role of the anti-bonding state in the electron correlations in Copper Oxide HTSC is analyzed. Then the t-J Hamiltonian is used to establish the formation of the charge stripes in underdoped oxides. It is proposed that these stripes make up the boundaries between the two degenerate anti-ferromagnetic (AFM) states, and that they are a key factor in switching between these states. We also provide a theoretical expression for the charge driven AFM magnons that have been observed by Neutron scattering experiments. Finally, the double correlation theory is applied to the stripe phase of holes to result in the superconductive gap and in the "pseudogap".

We draw analogies between the Carnot machines and possible devices employing such circuit element. We further point out the parallels between the operational principles of thermoelectric and magnetocaloritronic cooling and power generation and also introduce a magnetocaloritronic figure of merit. Even though the magnetocaloritronic figure of merit turns out to be very small for transition-metal based magnets, we speculate that larger numbers may be expected in ferromagnetic insulators.

description: AI for Biological Discovery: Data Integration and Self-Driving Instruments

Self-driving cars are changing transportation and setting a precedent for automated decision-making in the physical world.  Following that precedent, self-driving instruments will revolutionize the way in which experimental science is done. A major task in biomedical research is creating empiricalmodels that can predict, for example, how a person with a particular genetic makeup will respond to a particular drug. Predictive models are created from the results of some experiments to predict the outcome of others. The accuracy of a predictive model will in general be higher the more data is used to build it.  This is where integration of as many existing data sources as possible is critical.  However, we have data for only a tiny fraction of possible experiments, and there are experiments that we can’t or don’t want to do (such as treating a person with all possible drugs to see which works the best against their disease). We need a means of deciding which new experiments are best to do to improve our models. An important idea is to use our current predictive model to decide which experiments to do next (and rebuild the model) – an approach called activemachine learning.  The idea is to continuously try to improve the model (e.g., by choosing experiments whose outcome the model cannot confidently predict). The experiments themselves can nowadays often be executed using automated instruments.  The combination of active machine learning and automated instruments leads to automated science: experiments are not only executedusing robotic equipment but the choice of experiments is also made by computer – a combination we term “self-driving instruments.”  We have shown that automated science can produce an accurate model of drug effects while performing only a fraction of possible experiments.  Of course, just as self-driving cars don’t decide where you want to go, self-driving instruments need to be given a goal.  The promise is to build useful predictive models much more efficiently (in terms of time, money and reducing duplication of effort) than is possible with current human directed efforts.

description: In momentum transfer, the fluid is treated as a continuous distribution of matter. The study of momentum transfer, or fluid mechanics can be divided into two branches: fluid statics (fluids at rest), and fluid dynamics (fluids in motion). Fluid statics or hydrostatics is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body "fluids at hydrostatic equilibrium and the pressure in a fluid, or exerted by a fluid, on an immersed body". It encompasses the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics, the study of fluids in motion. Hydrostatics is a subcategory of fluid statics, which is the study of all fluids, both compressible or incompressible, at rest. Due to the fundamental nature of fluids, a fluid cannot remain at rest under the presence of a shear stress. However, fluids can exert pressure normal to any contacting surface. If a point in the fluid is thought of as an infinitesimally small cube, then it follows from the principles of equilibrium that the pressure on every side of this unit of fluid must be equal. If this were not the case, the fluid would move in the direction of the resulting force. Thus, the pressure on a fluid at rest is isotropic; namely it acts with equal magnitude in all directions. This characteristic allows fluids to transmit force through the length of pipes or tubes; namely a force applied to a fluid in a pipe is transmitted, via the fluid, to the other end of the pipe. In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids-liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications. Fluid dynamics offers a systematic structure, which underlies these practical disciplines, that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.

description: We define iterated monodromy groups of more general structures than partial self-covering. This generalization makes it possible to define a natural notion of a combinatorial model of an expanding dynamical system. We prove that a naturally defined "Julia set" of the generalized dynamical systems depends only on the associated iterated monodromy group. We show then that the Julia set of every expanding dynamical system is an inverse limit of simplicial complexes constructed by inductive cut-and-paste rules.

The first-order relativistic wave equation in the 20-dimensional matrix form is derived. We prove that the matrices of the equation obey the Petiau-Duffin-Kemmer algebra. The Hermitianizing matrix and Lagrangian in the first-order formalism are given. The projection operators extracting solutions of field equations for states with definite energy-momentum and spin projections are obtained, and we find the density matrix for the massive state. The $13\times 13$-matrix Schrodinger form of the equation is derived, and the Hamiltonian is obtained. Projection operators extracting the physical eigenvalues of the Hamiltonian are found.

description: We study the behavior of a Bose-Einstein condensate in which atoms are weakly coupled to a highly excited Rydberg state. Since the latter have very strong van der Waals interactions, this coupling induces effective, nonlocal interactions between the dressed ground state atoms, which, opposed to dipolar interactions, are isotropically repulsive. Yet, one finds partial attraction in momentum space, giving rise to a roton-maxon excitation spectrum and a transition to a supersolid state in three-dimensional condensates. A detailed analysis of decoherence and loss mechanisms suggests that these phenomena are observable with current experimental capabilities.

Given an $A^{(m)}$-module $T$, we denote by $δ(T)$ the number of non isomorphic indecomposable summands of $T$. In this paper, we prove that a partial tilting $A^{(m)}$-module $T$ is a tilting $A^{(m)}$-module if and only if $δ(T)=δ(A^{(m)})$, and that every partial tilting $A^{(m)}$-module has complements. As an application, we deduce that the tilting quiver $\mathscr{K}_{A^{(m)}}$ of $A^{(m)}$ is connected. Moreover, we investigate the number of complements to almost tilting modules over duplicated algebras.

description: A number of datasets for Relation Extraction (RE) have been created to aide downstream tasks such as information retrieval, semantic search, question answering and textual entailment. However, these datasets fail to capture financial-domain specific challenges since most of these datasets are compiled using general knowledge sources such as Wikipedia, web-based text and news articles, hindering real-life progress and adoption within the financial world. To address this limitation, we propose REFinD, the first large-scale annotated dataset of relations, with $\sim$29K instances and 22 relations amongst 8 types of entity pairs, generated entirely over financial documents. We also provide an empirical evaluation with various state-of-the-art models as benchmarks for the RE task and highlight the challenges posed by our dataset. We observed that various state-of-the-art deep learning models struggle with numeric inference, relational and directional ambiguity.

Assessing work-based learning on tourism and hospitality programmes in Irish higher education – the view from three main stakeholders (students, industry, HEI staff)
Creators: name: Carty, John
Publisher: name: Lancaster University
Year: 2021

description: The tourism and hospitality industry has been at the forefront in partnerships with higher education for many years and a key feature of this relationship is work-based learning, which sees students enter industry-partner workplaces as part of their study. The main issues with work-based learning are the lack of consistency across and within higher education institutes, the tensions that exist between the stakeholders and the changing higher education sector that is impacted by a neoliberalism agenda and marketisation, resulting in a push for employable graduates. The Covid19 pandemic and negative industry image present challenges for higher education and tourism and hospitality, whilst the work-based learning power imbalance has also led to an attitude of servitude from higher education institutes towards industry. The research utilises the community of practice theoretical framework and a case study approach to investigate these issues in an Irish context by assessing work-based learning from the viewpoint of three key stakeholders: students, industry and higher education institute staff. Fifty-seven surveys were conducted with students at one higher education institute and 20 semi-structured interviews were conducted with higher education staff (n=13) and tourism and hospitality industry professionals (n=7). The main finding of this research is the variety and inconsistencies that prevail within and across higher education institutes regarding work-based learning, fragmented partnerships and the opportunities and challenges of assessment. Resourcing work-based learning was found to be a significant issue that attracts high costs for higher education and industry partners, but research shows evidence of low investment. Assessment of work-based learning varies greatly, and a more consistent approach is suggested for the sector, with special attention given to the role of industry and the scheduling of assessments to allow for more meaningful and consistent work-based learning experiences. The research recommends a refocusing of work-based learning on the learner and presents the Learner Focused Work-Based Learning Framework to create more effective partnerships and address consistency across the landscape, overseen by a national oversight group.

description: There has been disagreement currently about whether cooling in protoplanetary disks can be sufficiently fast to induce the formation of gas giant protoplanets via gravitational instabilities. Simulations by our own group and others indicate that this method of planet formation does not work for disks around young, low- mass stars inside several tens of AU, while simulations by other groups show fragmentation into protoplanetary clumps in this region. To allow direct comparison in hopes of isolating the cause of the differences, we here present a high resolution three-dimensional hydrodynamics simulation of a protoplanetary disk, where the disk model, initial perturbation, and simulation conditions are essentially identical to those used in a set of simulations by Boss. As in earlier papers by the same author, Boss (2007, hereafter B07) purports to show that cooling is fast enough to produce protoplanetary clumps. Here, we evolve the same B07 disk using an improved version of one of our own radiative schemes and find that the disk does not fragment in our code but instead quickly settles into a state with only low amplitude nonaxisymmetric structure, which persists for at least several outer disk rotations. We see no rapid radiative or convective cooling. We conclude that the differences in results are due to different treatments of regions at and above the disk photosphere, and we explain at least one way in which the scheme in B07 may lead to artificially fast cooling.

Contribution of Vision and Proprioception to the Precision of Reaching Movements

description: Ren and colleagues (2006) found that saccades to visual targets became less accurate when somatosensory information about hand location was added, suggesting that saccades rely mainly on vision. We conducted two kinematic experiments to examine whether or not reaching movements would also show such strong reliance on vision. In Experiment 1, subjects used their dominant right hand to perform reaches, with or without a delay, to an external visual target or to their own left fingertip positioned either by the experimenter or by the participant. Unlike saccades, reaches became more accurate and precise when proprioceptive information was available. In Experiment 2, subjects reached toward external or bodily targets with differing amounts of visual information. Proprioception improved performance only when vision was limited. Our results indicate that reaching movements, unlike saccades, are improved rather than impaired by the addition of somatosensory information.

description: A rigorous quantum theory of atomic collisions in the presence of radio frequency (rf) magnetic fields is developed and applied to elucidate the effects of combined dc and rf magnetic fields on elastic scattering in ultracold collisions of Rb atoms. We show that rf fields can be used to induce Feshbach resonances, which can be tuned by varying the amplitude and frequency of the rf field. The rf-induced Feshbach resonances occur also in collisions of atoms in low-field-seeking states at moderate rf field strengths easily available in atom chip experiments, which opens up the world of tunable interactions to magnetically trappable atomic quantum gases.

description: In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. This state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but they are equal. Thus, there are no net changes in the concentrations of the reactants and products. Such a state is known as dynamic equilibrium. Equilibrium can be broadly classified as heterogeneous and homogeneous equilibrium. Homogeneous equilibrium consists of reactants and products belonging in the same phase whereas heterogeneous equilibrium comes into play for reactants and products in different phases. In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its individual parts is zero. In addition to defining mechanical equilibrium in terms of force, there are many alternative definitions for mechanical equilibrium which are all mathematically equivalent. In terms of momentum, a system is in equilibrium if the momentum of its parts is all constant. In terms of velocity, the system is in equilibrium if velocity is constant. In a rotational mechanical equilibrium, the angular momentum of the object is conserved and the net torque is zero. More generally in conservative systems, equilibrium is established at a point in configuration space where the gradient of the potential energy with respect to the generalized coordinates is zero. If a particle in equilibrium has zero velocity, that particle is in static equilibrium. Since all particles in equilibrium have constant velocity, it is always possible to find an inertial reference frame in which the particle is stationary with respect to the frame.

description: The survey approachs the issue of health and the problem of its effective protection in a context of deprivation of liberty and coercion, which is the prison.
The theoretical reflection born from the reform of the Legislative Decree 230/99 which marked the transition from an employee by the Prison Health within prison a fully integrated in the National Health Service. The comparison between an institution of health promotion and institution of punishment which may operate on the same subject held produces multiple attrits, making their relationship problematic. The work shows the daily difficulties in the management of prison health within the institution, physician-patient between different health care roles, and between the latter and prison workers. The coexistence, in fact, is not always harmonious though quite often it is common sense and the willingness of operators to reduce barriers: overcrowding, limited resources and insufficient staff make the application of the rule and therefore the right to goal a difficult to be pursued.
It is designed for a scheme of semi-structured interview essay is divided into 3 sections covering: "staff and its functions", "health reform" and "health of the prisoner"; questions were directed to doctors, nurses and psychologists engaged inside the prison of Rimini with the specific aim of examining the ambivalent relationship between the demand for health care in prisons and the need for security and a clear - albeit partial - point of view. We tried to reconstruct the situation of prison health care through the perception of prison operators, capturing the problematic issues that deal on both issues is instrumental to the experience of persons detained by analyzing, in terms of operators , what happens inside of a prison institution in everyday health care.

description: In the previous version of this paper we prove a theorem on the boundary behavior of the conical plurisubharmonic measure. However, the proof turns out to be incomplete. In the present version we give a corrected proof of this theorem. We next apply it to the theory of separately holomorphic functions. These applications are presented in a more accessible way than in the previous version.
