description: The discoveries that GRBs have X-ray, optical and radio afterglows have connected the study of GRBs to the rest of astronomy, and revolutionized the field. In this review, I discuss the implications that the observation of these afterglows have for burst energies and luminosities, and for models of the bursts and their afterglows. I describe recent evidence linking the long, softer, smoother GRBs detected by BeppoSAX and core collapse supernovae. Finally, I summarize recent work showing that, if these GRBs are due to the collapse of massive stars, they may provide a powerful probe of the very high redshift universe.

description: Four molluscan assemblage zones in southern Florida corresponding to the Pinecrest Sand Member of the Tamiami Formation, and the Caloosahatchee, Bermont and Fort Thompson shell beds were identified following quantitative and qualitative analyses of the fossil molluscan fauna. Twenty-eight bulk sediment samples collected from 16 localities across southern Florida were processed for fossil material, and yielded nearly 60,000 specimens belonging to 311 species. A Q-mode cluster analysis compared sediment samples on the basis of 188 species whose abundances had been converted to binary presence-absence form. The cluster analysis was run four times using the Jaccard and Dice similarity coefficients as well as weighted and unweighted pair-group averaging methods. Results of the analysis remained the same despite these different clustering techniques, and thus supported the robustness of the data. Careful examination of paleoecological and age relationships between clusters and their characteristic taxa revealed that clusters formed as a result of age similarities among collections. Index species for each biostratigraphic unit were identified and provide valuable tools for recognizing these units in the field. Further study may yield tests on the utility and validity of the suggested index species.

description: We study the dynamics of Green-Schwarz superstring on the gravitational wave background corresponding to the Matrix string theory and the supersymmetry transformation rules of the superstring. The dynamics is obtained in the light-cone formulation and is shown to agree with that derived from the Matrix string theory. The supersymmetry structure has the corrections due to the effect of the background and is identified with that of the low energy one-loop effective action of Matrix string theory in two superstring background in the weak string coupling limit.

Restrained eating behavior, anorexia nervosa and food consumption: a scoping review protocol
Creators: name: PEREIRA, EMILE

Subjects: subject: Medicine and Health Sciences
subject: Restrained eating behavior, anorexia nervosa and food consumption

description: Anorexia nervosa is a serious eating disorder and has one of the highest mortality rates among all psychiatric disorders. One of the important characteristics of this eating disorder is the adoption of dieting restrictive due to body dissatisfaction and fear to gain weight. However, individuals may also develop disordered eating behavior in the absence of an eating disorder such as anorexia nervosa, but it involves heir centrality to achieve the ideal of a lean body that directs them to excessive preoccupation with food and consequent damage in psychological, emotional and nutritional aspects. Studies results show that food intake is a potential bidirectional behavioral factor related to the development and / or maintenance of food restriction behavior and anorexia nervosa. Therefore, this review aims to evaluate the breadth and extent of the current state of evidence on the association between restrained eating behavior / anorexia nervosa and food intake.

description: Multiharmonic ac-magnetic susceptibility \ch11,\chi2,chi3, of neutron irradiated Li-doped YBa2Cu3O7-x has revealed a nonmonotonic dependence of all harmonics on the neutron fluence. The irradiation has a strongly depressive influence on the intergrain connection suggesting an increase of the effective thickness of the intergranular Josephson junction at aneutron fluence of 0.98x10$^{17}$ cm$_{-2}$. Less damaged are the intragrain properties. A spectacular enhancement of the superconducting intragranular properties reflected in the characteristics of all harmonics was observed at highest fluence Φ= 9.98x10$^{17}$ cm$_{-2}$. We assume that this effect results from the development of a space inhomogeneous distribution with alternating defectless and defect rich regions.

String Field Theory Around the Tachyon Vacuum

description: Assuming that around the tachyon vacuum the kinetic term of cubic open string field theory is made purely of ghost operators we are led to gauge invariant actions which manifestly implement the absence of open string dynamics around this vacuum. We test this proposal by showing the existence of lump solutions of arbitrary codimension in this string field theory. The key ingredients in this analysis are certain assumptions about the analyticity properties of tachyon Green's functions. With the help of some further assumptions about the properties of these Green's functions, we also calculate the ratios of tensions of lump solutions of different dimensions. The result is in perfect agreement with the known answers for the ratios of tensions of D-branes of different dimensions.

description: Knowledge about fertiliser limitation to soil microbes is crucial for exploring microbial community succession and ecosystem functions. In this study, an experiment was conducted to promote ecological restoration by different treatments of organic fertiliser (OF), microbial fertiliser (MF) and non-fertiliser (CK) in a coal mine dump. We investigated microbial community structure using high-throughput sequencing. Soils under OF and MF treatment showed distinct community structures with highly bacterial α-diversity due to the variation of soil pH and organic matters (SOM). Of those, the community dissimilarity between OF and CK was higher. The DistLM analysis indicated that SOM and available nitrogen (AN) significantly influenced microbial community structure. Furthermore, functional annotation by the FAPROTAX revealed that the functional groups associating with C, N, and S cycling increased significantly under OF and MF treatment, but decreased that associated with parasites or symbionts. Compared with MF, the functional groups with OF treatment varied greatly. However, the function groups including nitrogen_fixation, hydrocarbon_degradation and methanotrophy were significantly improved under the MF treatment, which have an important implication for soil quality and microbial growth. It was concluded that MF treatment could improve microbial community structure and enhance potential ecosystem function in coal mine dump soils.
A new perspective on the Fano absorption spectrum in terms of complex spectral analysis

description: A new aspect of understanding a Fano absorption spectrum is presented in terms of the complex spectral analysis. The absorption spectrum of an impurity embedded in semi-infinite superlattice is investigated. The boundary condition on the continuum causes a large energy dependence of the self-energy, enhances the nonlinearity of the eigenvalue problem of the effective Hamiltonian, yielding several nonanalytic resonance states. The overall spectral features is perfectly reproduced by the direct transitions to these discrete resonance states. Even with a single optical transition path the spectrum exhibits an asymmetric Fano profile, which is enhanced for the transition to the nonanalytic resonance states. Since this is the genuine eigenstates of the total Hamiltonian, there is no ambiguity in the interpretation of the absorption spectrum, avoiding the arbitrary interpretation based on the quantum interference. The spectral change around the exceptional point is well understood when we extract the resonant state component.

description: New photometric solutions have been carried out on the important eccentric eclipsing system V380 Cygni (B1.5II-III + B2V) from UBV differential photoelectric photometry obtained by us. The photometric elements obtained from the analysis of the light curves have been combined with the spectroscopic solution recently published by Popper & Guinan and have led to the physical properties of the system components. The effective temperature of the stars has been determined by fitting IUE UV spectrophotometry to Kurucz model atmospheres and compared with other determinations from broad-band and intermediate-band standard photometry. The values of mass, absolute radius, and effective temperature, for the primary and secondary stars are: 11.1+/-0.5 Mo, 14.7+/-0.2 Ro, 21350+/-400 K, and 6.95+/-0.25 Mo, 3.74+/-0.07 Ro, 20500+/-500 K, respectively. In addition, a re-determination of the system's apsidal motion rate has been done from the analysis of 12 eclipse timings obtained from 1923 to 1995. Using stellar structure and evolutionary models with modern input physics, tests on the extent of convection in the core of the more massive star of the system have been carried out. Both the analysis of the log g-log Teff diagram and the apsidal motion study indicate a star with a larger convective core, and thus more centrally condensed, than currently assumed. This has been quantified in form of an overshooting parameter with a value of 0.6+/-0.1. Finally, the tidal evolution of the system (synchronization and circularization times) has also been studied.

Abstract: Artificial Intelligence (AI) has significantly advanced in recent years, driving innovation across various fields, especially in robotics. Even though robots can perform complex tasks with increasing autonomy, challenges remain in ensuring explainability and user-centered design for effective interaction. A key issue in Human-Robot Interaction (HRI) is enabling robots to effectively perceive and reason over multimodal inputs, such as audio and vision, to foster trust and seamless collaboration. In this paper, we propose a generalized and explainable multimodal framework for context representation, designed to improve the fusion of speech and vision modalities. We introduce a use case on assessing ‘Relevance’ between verbal utterances from the user and visual scene perception of the robot. We present our methodology with a Multimodal Joint Representation module and a Temporal Alignment module, which can allow robots to evaluate relevance by temporally aligning multimodal inputs. Finally, we discuss how the proposed framework for context representation can help with various aspects of explainability in HRI.

title: Hydrogeologic Variations Across a Barrier Island that Influence Inter-Dune Wetlands False Cape State Park, Virginia
Creators: name: Richardson, Matthew Collier
Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98
publisherIdentifierScheme: ROR
Year: 2013

description: False Cape State Park in southeastern Virginia Beach, Virginia contains a transgressive barrier island complex. Inter-dune swales located on the eastern coast of the barrier island contain soils that experience hydric conditions. However, these swales lack the prolonged presence of hydric soil indicators that are necessary for a site to be officially recognized as a jurisdictional wetland. The appearance and subsequent disappearance of redoximorphic wetland soil features in the young, sandy soils of the inter-dune swales here may stem from changes in the patterns of groundwater recharge and discharge across the island. These soils are being monitored by the Mid Atlantic Hydric Soils committee and features there may be proposed for formal recognition as hydric soil indicators.

Hydraulic head data indicate that a strongly asymmetric freshwater lens crests under the eastern half of the island. The asymmetric shape of the water table could be due to differences in either vegetation cover or permeability of stratigraphic packages. The densely-vegetated western half of the island experiences higher rates of evapotranspiration (ET) than the more open-canopied eastern half. Permeameter testing and grain size analysis indicates slight differences in the permeability and grain size between the soils of each respective island half. Stratigraphic analyses of ground penetrating radar (GPR) data suggest the upper beds of the island have relatively minor permeability contrasts that will not significantly affect shallow groundwater flow patterns in models and in the field. Analyses of annual-scale groundwater variation made using a MODFLOW - based package showed that the asymmetric shaped water table depended mostly on spatial variation in permeability and recharge. Results of groundwater models indicate that the spatial differences in ET are the dominant factor controlling the shape of the barrier island water table. Historic hydrographs created for the inter-dune swale demonstrate that regardless of the wetness period, the swale almost always experiences wetland hydrology conditions. This study may ultimately aid in the development of inter-dune hydric soil indicators.

description: We present a three-dimensional (3D) common-refinement method for non-matching meshes between discrete non-overlapping subdomains of incompressible fluid and nonlinear hyperelastic structure. To begin, we first investigate the accuracy of common-refinement method (CRM) to satisfy traction equilibrium condition along the fluid-elastic interface with non-matching meshes. We systematically assess the accuracy of CRM against the matching grid solution by varying grid mismatch between the fluid and solid meshes over a cylindrical tubular elastic body. We demonstrate second-order accuracy of CRM through uniform refinements of fluid and solid meshes along the interface. We then extend the error analysis to transient data transfer across non-matching meshes between fluid and solid solvers. We show that the common-refinement discretization across non-matching fluid-structure grids yields accurate transfer of the physical quantities across the fluid-solid interface. We next solve a 3D benchmark problem of a cantilevered hyperelastic plate behind a circular bluff body and verify the accuracy of coupled solutions with respect to the available solution in the literature. By varying the solid interface resolution, we generate various non-matching grid ratios and quantify the accuracy of CRM for the nonlinear structure interacting with a laminar flow. We illustrate that the CRM with the partitioned NIFC treatment is stable for low solid-to-fluid density ratio and non-matching meshes. Finally, we demonstrate the 3D parallel implementation of common-refinement with NIFC scheme for a realistic engineering problem of drilling riser undergoing complex vortex-induced vibration with strong added mass effects.

Non-dissipative drag of superflow in a two-component Bose gas

Year: 2005
Subjects: subject: Other Condensed Matter (cond-mat.other)

description: A microscopic theory of a non-dissipative drag in a two-component superfluid Bose gas is developed. The expression for the drag current in the system with the components of different atomic masses, densities and scattering lengths is derived. It is shown that the drag current is proportional to the square root of the gas parameter. The temperature dependence of the drag current is studied and it is shown that at temperature of order or smaller than the interaction energy the temperature reduction of the drag current is rather small. A possible way of measuring the drag factor is proposed. A toroidal system with the drag component confined in two half-ring wells separated by two Josephson barriers is considered. Under certain condition such a system can be treated as a Bose-Einstein counterpart of the Josephson charge qubit in an external magnetic field. It is shown that the measurement of the difference of number of atoms in two wells under a controlled evolution of the state of the qubit allows to determine the drag factor.

description: We investigate a distributed optimal control problem for a phase field model of Cahn-Hilliard type. The model describes two-species phase segregation on an atomic lattice under the presence of diffusion; it has been introduced recently in [4], on the basis of the theory developed in [15], and consists of a system of two highly nonlinearly coupled PDEs. For this reason, standard arguments of optimal control theory do not apply directly, although the control constraints and the cost functional are of standard type. We show that the problem admits a solution, and we derive the first-order necessary conditions of optimality.

description: Microchannel plate photodetectors provide both picosecond time resolution and sub-millimeter position resolution, making them attractive photosensors for particle identification detectors of a future U.S. Electron Ion Collider. We have tested the rate capability and magnetic field tolerance of 6$\times$6 cm$^{2}$ microchannel plate photodetectors fabricated at Argonne National Laboratory. The microchannel plate photodetector is designed as a low-cost all-glass vacuum package with a chevron pair stack of next-generation microchannel plates functionalized by atomic layer deposition. The rate capability test was performed using Fermilab's 120 GeV primary proton beam, and the magnetic field tolerance test was performed using a solenoid magnetic with tunable magnetic field strength up to 4 Tesla. The measured gain of the microchannel plate photodetector is stable up to 75 kHz/cm$^{2}$, and varies depending on the applied magnetic field strength and the rotation angle relative to the magnetic field direction.

description: In this paper, we prove a kind of Abelian theorem for a class of stochastic volatility models $(X, V)$, where both the state process $X$ and the volatility process $V$ may have jumps. Our results relate the asymptotic behavior of the characteristic function of $X_Delta$ for some $Delta > 0$ in a stationary regime to the Blumenthal-Getoor indexes of the Lévy processes driving the jumps in $X$ and $V$ . The results obtained are used to construct consistent estimators for the above Blumenthal-Getoor indexes based on low-frequency observations of the state process $X$. We derive the convergence rates for the corresponding estimator and prove that these rates can not be improved in general.

description: An interesting problem in statistical physics is the condensation of classical particles in droplets or clusters when the pair-interaction is given by a stable Lennard-Jones-type potential. We study two aspects of this problem. We start by deriving a large deviations principle for the cluster size distribution for any inverse temperature $betain(0,infty)$ and particle density $rhoin(0,rho_rmcp)$ in the thermodynamic limit. Here $rho_rmcp >0$ is the close packing density. While in general the rate function is an abstract object, our second main result is the $Gamma$-convergence of the rate function towards an explicit limiting rate function in the low-temperature dilute limit $betatoinfty$, $rho downarrow 0$ such that $-beta^-1logrhoto nu$ for some $nuin(0,infty)$. The limiting rate function and its minimisers appeared in recent work, where the temperature and the particle density were coupled with the particle number. In the de-coupled limit considered here, we prove that just one cluster size is dominant, depending on the parameter $nu$. Under additional assumptions on the potential, the $Gamma$-convergence along curves can be strengthened to uniform bounds, valid in a low-temperature, low-density rectangle.

Monsieur,

Quoi que je sois pris de douleurs de rhumatisme qui m'empêchent d'agir et de m'occuper, je ne veux pas différer à vous informer de ce que le Père Fabricy m'a fait savoir dans sa lettre du 28e avril dernier en écrivant au père Clapiers, prieur des dominicains de cette ville, qui est venu avant-hier chez moi pour le communiquer.

Ce père s'excuse d'abord sur les circonstances des temps où il s'est trouvé qui ne lui ont permis encore de me répondre, mais que malgré ses occupations il s'en acquittera le plus tôt possible et qu'il répondra aussi à vos lettres que je lui envoyai avec la mienne. Il a déjà fait tout ce qu'il a pu sans cependant beaucoup espérer d'avoir le peu de lettres manuscrites de Peiresc. Il vous en rendra raison dans la lettre qu'il doit vous écrire. Il me charge de vous en prévenir et de vous en faire ses excuses. Il a fait une copie du testament d'Holstenius d'après l'imprimé qui s'en trouve dans les Analaecta Vindobonensia de Kollarius qui se sont trouvés dans la Bibliohèque de la Minerve. Il me marque ensuite qu'aucun des antiquaires qu'il a consultés ne connaît point les bas reliefs représentant l'Excidium Templi Delphici a Gallis excisis, dont fait mention Holstenius.

Vous voyez que cet obligeant religieux ne nous oublie point et qu'il nous donnera bientôt des nouvelles plus détaillées de tout ce qu'il aura fait. L'état où je me trouve ne me permet pas d'allonger la lettre. J'ai l'honneur d'être avec les sentiments d'attachement et d'amitié que je vous conserve votre très humble et obéissant serviteur,

description: In this paper, we introduce a benchmark for evaluating the overall quality of emergent languages using data-driven methods. Specifically, we interpret the notion of the "quality" of an emergent language as its similarity to human language within a deep learning framework. We measure this by using the emergent language as pretraining data for a downstream NLP tasks in human language -- the better the downstream performance, the better the emergent language. We implement this benchmark as an easy-to-use Python package that only requires a text file of utterances from the emergent language to be evaluated. Finally, we empirically test the benchmark's validity using human, synthetic, and emergent language baselines.

description: We analyze a rate-independent model for damage evolution in elastic bodies. The central quantities are a stored energy functional and a dissipation functional, which is assumed to be positively homogeneous of degree one. Since the energy is not simultaneously (strictly) convex in the damage variable and the displacements, solutions may have jumps as a function of time. The latter circumstance makes it necessary to recur to suitable notions of weak solution. However, the by-now classical concept of global energetic solution fails to describe accurately the behavior of the system at jumps. Hence, we consider rate-independent damage models as limits of systems driven by viscous, rate-dependent dissipation. We use a technique for taking the vanishing viscosity limit, which is based on arc-length reparameterization. In this way, in the limit we obtain a novel formulation for the rate-independent damage model, which highlights the interplay of viscous and rate-independent effects in the jump regime, and provides a better description of the energetic behavior of the system at jumps.

description: Background: Posttraumatic stress disorder (PTSD) is considered an independent risk factor for dementia. Despite the (clinical) evidence that PTSD is associated with neuropsychiatric symptoms in people with dementia, studies on its prevalence and clinical manifestation are limited, and their quality is affected by the lack of a structured method to diagnose PTSD in this population. The primary aim of the current study is to validate the ‘TRAuma and DEmentia’ interview as a diagnostic tool for PTSD in people with dementia and to test feasibility of EMDR treatment for people with PTSD and dementia. Methods: This prospective multi-centre study is divided into two parts. In study A, 90 participants with dementia will be included to test the criterion validity, inter-rater reliability and feasibility of the ‘TRAuma and DEmentia’ interview. In study B, 29 participants with dementia and PTSD will receive eye movement desensitisation and reprocessing therapy by a trained psychologist, and 29 participants with dementia and PTSD will be placed on the waiting list control group. Conclusion: This study aims to improve the diagnostic process of PTSD and to assess the effects of eye movement desensitisation and reprocessing treatment in people with dementia living in Dutch care facilities.

Non-monotonic transformation kinetics and the morphological stability of phase boundaries in thermoelastic materials

description: Abstract: "The linear stability of an isothermal two-phase process involving a planar phase boundary of normal type is analyzed. Results are obtained for cases wherein: i. the temperature field is unaltered as a consequence of the disturbance which is imposed, ii. the process is initially static, iii. the phase boundary associated with the process propagates steadily with non-zero velocity. In the first case the linear stability criteria are equivalent to those obtained in a related purely mechanical investigation. In the second case the process is found to be linearly stable. In the last case it is shown that instability can arise under a variety of circumstances. Of particular interest is a case where the kinetic relation is mechanically stable but thermally unstable; in this case the transformation process is unstable with respect to disturbances which include only suitably long waves, implying that a state involving a highly wrinkled interface is favored over one involving a planar interface."
The Influence of Neutron Irradiation on (B0.65C0.35)Ba1.4Sr0.6Ca2Cu3Oz Superconducting Phase: the Role of the Grain Edge

description: Using the transport and magnetization measurements the influence of neutron irradiation at a fluence of 5x10$^{17}$ n cm$^{-2}$ on (B0.65C0.35)Ba1.4Sr0.6Ca2Cu3Oz has been investigated. The neutron irradiation was found to decrease critical temperature and transport critical current density, increase the residual and normal state resistivity, and improve the intragranular critical current density with 1.6x10$^{57}$ A/cm$^{2}$ (at 77.3K and in the applied field up to 160 kA m) and ΔMirr/ΔMnonirr ratio (up to factor of 3) at highest field used for investigation. The field dependence of this ratio, which is below the unity at very low field but higher than 1 at high fields, correlated with the shape of the hystertic loops as well as with the change of the transport parameters after irradiation suggests the role of the irradiation induced effects on the grain edges. We discuss these effects in the framework of the Bean-Livingstone surface barriers and geometrical barriers.

description: This paper deals with the study of a three-dimensional model of thermomechanical coupling for viscous solids exhibiting hysteresis effects. This model is written in accordance with the formalism of generalized standard materials. It is composed by the momentum equilibrium equation combined with the flow rule, which describes some stress-strain dependance, and the heat-transfer equation. An existence result for this thermodynamically consistent problem is obtained by using a fixed-point argument and some qualitative properties of the solutions are established.

description: An explanation is offered for the large anomalous electro-optic (e.o.) effect reported by Fujiwara in 1994. It is based on the large e.o. coefficient of ordered water at an interface measured in recent years. The concept of water-based photonics is introduced, suggesting that liquid states of matter can allow ready shaping and exploitation of many processes in ways not previously considered.

description: We consider the contact between an electrolyte and a solid electrode. At first we formulate a thermodynamic consistent model that resolves boundary layers at interfaces. The model includes charge transport, diffusion, chemical reactions, viscosity, elasticity and polarization under isothermal conditions. There is a coupling between these phenomena that particularly involves the local pressure in the electrolyte. Therefore the momentum balance is of major importance for the correct description of the layers. The width of the boundary layers is typically very small compared to the macroscopic dimensions of the system. In a second step we thus apply the method of asymptotic analysis to derive a simpler reduced model that does not resolve the boundary layers but instead incorporates the electrochemical properties of the layers into a set of new boundary conditions. For a metal-electrolyte interface, we derive a qualitative description of the double layer capacitance without the need to resolve space charge layers.

description: We study the well-posedness of a class of nonlocal-interaction equations on general domains Ω⊂Rd, including nonconvex ones. We show that under mild assumptions on the regularity of domains (uniform prox-regularity), for λ-geodesically convex interaction and external potentials, the nonlocal-interaction equations have unique weak measure solutions. Moreover, we show quantitative estimates on the stability of solutions which quantify the interplay of the geometry of the domain and the convexity of the energy. We use these results to investigate on which domains and for which potentials the solutions aggregate to a single point as time goes to infinity. Our approach is based on the theory of gradient flows in spaces of probability measures
