description: Large language models (LLMs) are increasingly leveraged as foundational backbones in the development of advanced recommender systems, offering enhanced capabilities through their extensive knowledge and reasoning. Existing llm-based recommender systems (RSs) often face challenges due to the significant differences between the linguistic semantics of pre-trained LLMs and the collaborative semantics essential for RSs. These systems use pre-trained linguistic semantics but learn collaborative semantics from scratch via the llm-Backbone. However, LLMs are not designed for recommendations, leading to inefficient collaborative learning, weak result correlations, and poor integration of traditional RS features. To address these challenges, we propose EAGER-LLM, a decoder-only llm-based generative recommendation framework that integrates endogenous and exogenous behavioral and semantic information in a non-intrusive manner. Specifically, we propose 1)dual-source knowledge-rich item indices that integrates indexing sequences for exogenous signals, enabling efficient link-wide processing; 2)non-invasive multiscale alignment reconstruction tasks guide the model toward a deeper understanding of both collaborative and semantic signals; 3)an annealing adapter designed to finely balance the model's recommendation performance with its comprehension capabilities. We demonstrate EAGER-LLM's effectiveness through rigorous testing on three public benchmarks.

description: Sentiment Analysis has seen much progress in the past two decades. For the past few years, neural network approaches, primarily RNNs and CNNs, have been the most successful for this task. Recently, a new category of neural networks, self-attention networks (SANs), have been created which utilizes the attention mechanism as the basic building block. Self-attention networks have been shown to be effective for sequence modeling tasks, while having no recurrence or convolutions. In this work we explore the effectiveness of the SANs for sentiment analysis. We demonstrate that SANs are superior in performance to their RNN and CNN counterparts by comparing their classification accuracy on six datasets as well as their model characteristics such as training speed and memory consumption. Finally, we explore the effects of various SAN modifications such as multi-head attention as well as two methods of incorporating sequence position information into SANs.
Statistical Mechanics of Structural Fluctuations

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The theory of mesoscopic fluctuations is applied to inhomogeneous solids consisting of chaotically distributed regions with different crystalline structure. This approach makes it possible to describe statistical properties of such mixture by constructing a renormalized Hamiltonian. The relative volumes occupied by each of the coexisting structures define the corresponding geometric probabilities. In the case of a frozen heterophase system these probabilities should be given a priori. And in the case of a thermal heterophase mixture the structural probabilities are to be defined self-consistently by minimizing a thermodynamical potential. This permits to find the temperature behavior of the probabilities which is especially important near the points of structural phase transitions. The presense of these structural fluctuations yields a softening of a crystal and a decrease of the effective Debye temperature. These effects can be directly seen by nuclear gamma resonance since the occurrence of structural fluctuations is accompanied by a noticeable sagging of the Mössbauer factor at the point of structural phase transition. The structural fluctuations also lead to the attenuation of sound and increase of isothermic compressibility.

description: Convective motions in the solar atmosphere cause spectral lines to become asymmetric and shifted in wavelength. For photospheric lines, this differential Doppler shift varies from the solar disk center to the limb. Precise and comprehensive observations of the convective blueshift and its center-to-limb variation improve our understanding of the atmospheric hydrodynamics and ensuing line formation, and provide the basis to refine 3D models of the solar atmosphere. We performed systematical spectroscopic measurements of the convective blueshift of the quiet Sun with the Laser Absolute Reference Spectrograph (LARS) at the German Vacuum Tower Telescope. The spatial scanning of the solar disk covered four radial (meridional and equatorial) axes. The high-resolution spectra of 26 photospheric to chromospheric lines in the visible range were calibrated with a laser frequency comb to absolute wavelengths at the 1m/s accuracy. Applying ephemeris and reference corrections, the bisector analysis provided line asymmetries and Doppler shifts with an uncertainty of only few m/s. To allow for a comparison with other observations, we convolved the results to lower spectral resolutions. Typically, a blueshifted "C"-shaped curve at disk center transforms into a less blueshifted "\"-shape toward the solar limb. The comparison of all lines reveals the systematic dependence of the convective blueshift on the line depth. Synthetic models yield considerable deviations from the observed center-to-limb variation. The obtained Doppler shifts of the quiet Sun can serve as an absolute reference for other observations, the relative calibration of Dopplergrams, and the necessary refinement of atmospheric models. Based on this, the development of high-precision models of stellar surface convection will advance the detection of (potentially habitable) exoplanets by radial velocity measurements.
title: Testing for the Diffusion Matrix in a Continuous-Time Markov Process Model with Applications to the Term Structure of Interest Rates
Creators: name: Li, Fuchun
Publisher: name: Bank of Canada
Year: 2015

description: The author proposes a test for the parametric specification of each component in the diffusion matrix of a d-dimensional diffusion process. Overall, d (d-1)/2 test statistics are constructed for the off-diagonal components, while d test statistics are constructed for the main diagonal components. Using theories of degenerate U-statistics, each of these test statistics is shown to follow an asymptotic standard normal distribution under null hypothesis, while diverging to infinity if the component is misspecified over a significant range. Our tests strongly reject the specification of diffusion functions in a variety of popular univariate interest rate models for daily 7-day eurodollar spot rates, and the specification of the diffusion matrix in some popular multivariate affine term-structure models for monthly U.S. Treasury yields.
description: L’auteur propose un test permettant de vérifier la validité de la spécification paramétrique des différentes composantes de la matrice de distribution d’un processus de distribution à d dimensions. À cette fin, il construit d(d-1)/2 statistiques de test pour les composantes hors-diagonale, et d statistiques pour les composantes de la diagonale principale. En se fondant sur les théories des U-statistiques dégénérées, l’auteur montre que chacune de ces statistiques de test suit asymptotiquement une loi de distribution normale sous l’hypothèse nulle, mais diverge à l’infini si la spécification de la composante est erronée sur une large fourchette. Ses tests invalident clairement la spécification des fonctions de distribution de divers modèles univariés de taux d’intérêt, très utilisés, lorsque ces modèles sont appliqués aux taux au comptant pour les dépôts à sept jours en eurodollars, ainsi que la spécification de la matrice de distribution utilisée dans certains modèles affines multivariés de la structure par terme, également très utilisés pour les rendements mensuels des titres du Trésor américain.

description: Synthetic hectorite clay Laponite RD/XLG is composed of disk-shaped nanoparticles that acquire dissimilar charges when suspended in an aqueous media. Owing to their property to spontaneously self-assemble, Laponite is used as a rheology modifier in a variety of commercial water-based products. Particularly, aqueous dispersion of Laponite undergoes liquid - to - solid transition at about 1 volume % concentration. The evolution of the physical properties as dispersion transforms to solid state is reminiscent of physical aging in molecular as well as colloidal glasses. The corresponding soft glassy dynamics of an aqueous Laponite dispersion, including the rheological behavior, has been extensively studied in the literature. In this feature article we take an overview of recent advances in understanding soft glassy dynamics and various efforts taken to understand the peculiar rheological behaviors. Furthermore, the continuously developing microstructure that is responsible for eventual formation of soft solid state that supports its own weight against gravity has also been a topic of intense debate and discussion. Particularly extensive experimental and theoretical studies lead to two types of microstructures for this system: an attractive gel-like or repulsive glass like. We carefully examine and critically analyze the literature and propose a state diagram that suggests aqueous Laponite dispersion to be present in an attractive gel state.

description: Heralding techniques are useful in quantum communication to circumvent losses without resorting to error correction schemes or quantum repeaters. Such techniques are realized, for example, by monitoring for photon loss at the receiving end of the quantum link while not disturbing the transmitted quantum state. We describe and experimentally benchmark a scheme that incorporates error detection in a quantum channel connecting two transmon qubits using traveling microwave photons. This is achieved by encoding the quantum information as a time-bin superposition of a single photon, which simultaneously realizes high communication rates and high fidelities. The presented scheme is straightforward to implement in circuit QED and is fully microwave-controlled, making it an interesting candidate for future modular quantum computing architectures.

description: Concept designers in the entertainment industry create highly detailed, often imaginary environments for movies, games, and TV shows. Their early ideation phase requires intensive research, brainstorming, visual exploration, and combination of various design elements to form cohesive designs. However, existing AI tools focus on image generation from user specifications, lacking support for the unique needs and complexity of concept designers' workflows. Through a formative study with 12 professional designers, we captured their workflows and identified key requirements for AI-assisted ideation tools. Leveraging these insights, we developed AIdeation to support early ideation by brainstorming design concepts with flexible searching and recombination of reference images. A user study with 16 professional designers showed that AIdeation significantly enhanced creativity, ideation efficiency, and satisfaction (all p<.01) compared to current tools and workflows. A field study with 4 studios for 1 week provided insights into AIdeation's benefits and limitations in real-world projects. After the completion of the field study, two studios, covering films, television, and games, have continued to use AIdeation in their commercial projects to date, further validating AIdeation's improvement in ideation quality and efficiency.

description: We study the behavior of gravitational waves and their backreaction on the background in cosmological solutions of the five-dimensional Hořava-Witten theory. As a dynamical background, we consider two cosmological solutions with spatially flat expanding FRW branes, called $(\uparrow)$- and $(\downarrow)$-solutions, in which the orbifold size increases and decreases in time, respectively. % For these background solutions, the wave equation for the tensor perturbation can be solved by the method of separation of variables, and the mode functions are classified by a separation constant which can be regarded as a graviton mass. We show that the spatial behavior of the mode functions are the same for both background solutions, but the temporal behavior is significantly different. We further show that for the $(\uparrow)$ solution, the background bulk geometry is unstable against the backreaction of the perturbation, while for the $(\downarrow)$ solution, the backreaction on the bulk geometry can be neglected. We also show that, in contrast to the effect to the bulk geometry, the backreaction of the perturbation significantly alters the intrinsic geometry of the brane for the $(\downarrow)$ solution.

Publisher: name: Bank of Canada
Year: 2015

description: We use internationally comparable household-level data for ten euro area economies and the United States to investigate cross-country differences in debt holdings and the potential of debt overhang. U.S. households have the highest prevalence of both collateralized and non-collateralized debt, hold comparatively large amounts of loans outstanding, and face a higher debt-service burden. These differences are mainly attributed to the U.S. economic environment, which appears to be more conducive to both types of debt. For instance, differences in the economic environment between the United States and the median European country explain more than 85% of the overall difference in the prevalence of debt holdings. Even though U.S. households have higher income and financial wealth than their European counterparts, their debt burden remains comparatively elevated, primarily because a given level of collateral translates into a higher prevalence of collateralized debt, and larger amounts of it, in the United States. This suggests that U.S. households are relatively more vulnerable to adverse shocks.
description: À partir de microdonnées sur les ménages exploitables à des fins de comparaison internationale, les auteurs étudient les différences dans le niveau d’endettement et la nature des dettes des ménages de dix pays de la zone euro et des États-Unis, et la possibilité que ces ménages se retrouvent en situation de surendettement. Les ménages américains sont proportionnellement les plus nombreux à contracter des emprunts garantis et non garantis; ils supportent aussi d’importants encours de dette comparativement aux ménages européens, et leur situation financière est davantage grevée par le service de la dette. Ces disparités sont essentiellement attribuables au contexte économique américain qui apparaît plus propice à la souscription des deux types d’emprunt. Par exemple, les différences de contexte économique sont à l’origine de plus de 85 % de l’écart entre les États-Unis et le pays européen médian dans les proportions de ménages endettées. Même si les ménages américains ont un niveau plus élevé de revenu et de patrimoine financier que les ménages européens, le service de la dette pèse plus lourdement sur leur situation financière du fait essentiellement qu’un montant de garantie donné se traduit aux États-Unis par une plus forte proportion de ménages souscripteurs d’emprunts garantis et des encours plus importants. Ces résultats donnent à penser que les ménages américains sont relativement plus vulnérables aux chocs négatifs.

description: We report on beating appearance in Shubnikov-de Haas oscillations in conduction band of 18-22nm HgTe quantum wells under applied top-gate voltage. Analysis of the beatings reveals two electron concentrations at the Fermi level arising due to Rashba-like spin splitting of the first conduction subband H1. The difference dN_s in two concentrations as a function of the gate voltage is qualitatively explained by a proposed toy electrostatic model involving the surface states localized at quantum well interfaces. Experimental values of dN_s are also in a good quantitative agreement with self-consistent calculations of Poisson and Schrodinger equations with eight-band kp Hamiltonian. Our results clearly demonstrate that the large spin splitting of the first conduction subband is caused by surface nature of $H1$ states hybridized with the heavy-hole band.

The Cost of an Insincere Performance: Motherhood and Punishment in Revolutionary Road, The Hours, and We Need to Talk About Kevin
Creators: name: Newton, Charli
Publisher: name: Monash University
Year: 2025

description: This essay examines Richard Yates’ Revolutionary Road (1961), Michael Cunningham’s The Hours (1998), and Lionel Shriver’s We Need to Talk About Kevin (2003) through the application of Adrienne Rich’s concept of maternal altruism and Michel Foucault’s Discipline and Punish (1975) and Technologies of the Self (1988). I argue that the aforementioned novels destabilise and subvert mythologies of motherhood and the nuclear family to expose the role of the twentieth-century American mother as a performative act. This subversion is exemplified through an array of central characters who undertake this performativity reluctantly and as the result of a societal coercion reinforced by a patriarchal hegemony that posits Rich’s maternal altruism as the universally-approved feature of womanhood., This essay seeks to demonstrate that what ensues as a result of the central characters’ failed attempt to perform motherhood intuitively is, in part, the rupture of the mother-child dynamic, enforced through the violent death of the child or childlike figure, a spectacle made public in line with Foucault’s theory on the nature of punishment.

description: Lattice relaxations, surface phonon spectra, surface energies, and work functions are calculated for Rh(100) and Rh(110) surfaces using density-functional theory and the full-potential linearized augmented plane wave method. Both, the local-density approximation and the generalized gradient approximation to the exchange-correlation functional are considered. The force constants are obtained from the directly calculated atomic forces, and the temperature dependence of the surface relaxation is evaluated by minimizing the free energy of the system. The anharmonicity of the atomic vibrations is taken into account within the quasiharmonic approximation. The importance of contributions from different phonons to the surface relaxation is analyzed.

Introducing $B_1$-embedding and $B_1^*$-embedding, several analogous results, especially, an analogue of Urysohn's extension theorem is established.

description: We have examined the spin polarization of the electron current in a ferromagnetic metal induced by the spin-dependent surface screening at the dielectric-ferromagnetic metal (D-FM) interface. In an applied ac voltage, the dynamic band splitting driven by the changes in the screening charge at the D-FM interface develops spin accumulation. The resultant spin accumulation gradient produces a time-dependent spin current. We have derived the rate of the spin accumulation on the rate of the screening charge density accumulation within the Stoner band model. The spin-charge dynamics in the system is then modeled by a set of diffusive equations with the contributions from spin-dependent surface screening ands spin-dependent conductivity. We show for MgO-Cu-Co-MgO system that the spin-dependent screening in thin Co film produces spin accumulation 7 times higher than that obtained by the spin-dependent conductivity in thick Co films. We propose an experimental approach to validate our numerical predictions and to distinguish between spin accumulation induced by the spin-dependent conductivity and by the spin-dependent surface screening.

description: Using the Panel Study of Income Dynamics, this paper studies household stock market participation and trading behavior in 2007–09, a period that saw a major stock market downswing. The stock market participation rate fell after the market crash. We find evidence that less-educated households, poor households and households with heads belonging to a minority are the ones that dropped out of the market after the market crash. We also find that, of the households that held stocks in non-retirement accounts in 2007, a significant portion reported no stock market activity in non-retirement accounts during the crisis period.

À la suite de l’effondrement des marchés, le taux de participation au marché boursier a chuté, et nous constatons que les ménages moins instruits, les ménages pauvres et les ménages dont le chef appartient à une minorité sont ceux qui ont quitté le marché à ce moment-là. Nous observons aussi qu’une proportion importante de ménages qui détenaient des actions dans des comptes autres que des comptes de retraite en 2007 n’ont déclaré aucune activité boursière liée à ces comptes pendant la crise.
title: A Wake-Up-Call Theory of Contagion

Year: 2015

description: We propose a novel theory of financial contagion. We study global coordination games of regime change in two regions with an initially uncertain correlation of regional fundamentals. A crisis in region 1 is a wake-up call to investors in region 2 that induces a reassessment of local fundamentals. Contagion after a wake-up call can occur even if investors learn that fundamentals are uncorrelated and common lender effects or balancesheet linkages are absent. Applicable to currency attacks, bank runs and debt crises, our theory of contagion is supported by existing evidence and generates a new testable implication for empirical work.
description: Les auteurs proposent une théorie inédite de la contagion financière. Ils étudient les jeux globaux de coordination autour d’un changement de régime dans deux régions dont les facteurs fondamentaux présentent initialement une corrélation incertaine. Une crise dans la première région envoie un signal d’alerte aux investisseurs de la seconde, ce qui pousse ces derniers à réévaluer les facteurs fondamentaux de leur propre région. Il peut y avoir contagion après l’envoi de ce signal, même si les investisseurs apprennent que les facteurs fondamentaux des deux régions ne sont pas corrélés et qu’on observe une absence d’effets de créancier commun ou de liens entre les bilans. Cette théorie de la contagion, qui s’applique aux attaques contre la monnaie, aux retraits massifs de dépôts bancaires et aux crises d’endettement, est corroborée par les données existantes et génère une nouvelle prédiction susceptible d’être testée par des travaux empiriques.

description: Using the lumped circuit equations, we derive a stability criterion for superconducting pinned states in two-dimensional arrays of Josephson junctions. The analysis neglects quantum, thermal, and inductive effects, but allows disordered junctions, arbitrary network connectivity, and arbitrary spatial patterns of applied magnetic flux and DC current injection. We prove that a pinned state is linearly stable if and only if its corresponding stiffness matrix is positive definite. This algebraic condition can be used to predict the critical current and frustration at which depinning occurs.

description: We elaborate on the recently proposed static brane world scenario, where the effective 4-D cosmological constant is exponentially small when parallel 3-branes are far apart. We extend this result to a compactified model with two positive tension branes. Besides an exponentially small effective 4-D cosmological constant, this model incorporates a Randall-Sundrum-like solution to the hierarchy problem. Furthermore, the exponential factors for the hierarchy problem and the cosmological constant problem obey an inequality that is satisfied in nature. This inequality implies that the cosmological constant problem can be explained if the hierarchy problem is understood. The basic idea generalizes to the multibrane world scenario. We discuss models with piecewise adjustable bulk cosmological constants (to be determined by the 5-dimensional Einstein equation), a key element of the scenario. We also discuss the global structure of this scenario and clarify the physical properties of the particle (Rindler) horizons that are present. Finally, we derive a 4-D effective theory in which all observers on all branes not separated by particle horizons measure the same Newton's constant and 4-D cosmological constant.

Collimated Fast Winds in Wide Binary Progenitors of Planetary Nebulae
Creators: name: Soker, Noam
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We discuss the formation of planetary nebulae (PNe) having a pair of lobes, or multi-lobes, in their inner region surrounded by an elliptical or spherical shell or halo. We suggest that most of these PNe are formed by wide binary systems, with final orbital periods in the range of 40-10,000 years, such that there is no strong tidal interaction. The outer more spherical structure is formed from the early asymptotic giant branch (AGB) wind. Toward the end of the AGB the mass loss rate increases, and wind velocity possibly decreases, making the conditions for the formation of an accretion disk around the wide companion, more favorable. We assume that the accreting companion blows jets or a collimated fast wind (CFW), which lead to the formation of a pair of lobes in the inner region. In cases of a precessing accretion disk, a multi-lobes structure can be formed. We conduct a population synthesis study of such systems, and find that overall 5-20 percents of all PNe are formed by such binary systems. We also estimate that 20-40 percents of these systems possess observable departure from axisymmetry, e.g., the central star is not in the center of the nebula.

Spin-charge separation and Kondo effect in an open quantum dot

description: We study a quantum dot connected to the bulk by single-mode junctions at almost perfect conductance. Although the average charge $e\langle N \rangle$ of the dot is not discrete, its spin remains quantized: $s=1/2$ or $s=0$, depending (periodically) on the gate voltage. This drastic difference from the conventional mixed-valence regime stems from the existence of a broad-band, dense spectrum of discrete levels in the dot. In the doublet state, the Kondo effect develops at low temperatures. We find the Kondo temperature $T_K$ and the conductance at $T\lesssim T_K$.

title: Euro Area Government Bonds—Integration and Fragmentation During the Sovereign Debt Crisis
Creators: name: Ehrmann, Michael
name: Fratzscher, Marcel
Publisher: name: Bank of Canada
Year: 2015

description: The paper analyzes the integration of euro area sovereign bond markets during the European sovereign debt crisis. It tests for contagion (i.e., an intensification in the transmission of shocks across countries), fragmentation (a reduction in spillovers) and flight-to-quality patterns, exploiting the heteroskedasticity of intraday changes in bond yields for identification. The paper finds that euro area government bond markets were well integrated prior to the crisis, but saw a substantial fragmentation from 2010 onward. Flight to quality was present at the height of the crisis, but has largely dissipated after the European Central Bank’s (ECB’s) announcement of its Outright Monetary Transactions (OMT) program in 2012. At the same time, Italy and Spain became more interdependent after the OMT announcement, providing our only evidence of contagion. While this suggests that countries have been effectively ring-fenced, and Italy and Spain benefited from the joint reduction in yields following the OMT announcement, the high current degree of fragmentation poses difficult challenges for policy-makers, since it leads to an unequal transmission of the ECB’s monetary policy to the various countries.
description: Dans la présente étude, les auteurs examinent le degré d’intégration des marchés des obligations d’État de la zone euro durant la crise de la dette souveraine en Europe. Ils recherchent des indices de contagion (intensification de la propagation des chocs entre les pays), de fragmentation (réduction des effets de débordement) et de fuite vers les titres de qualité en s’appuyant sur l’hétéroscédasticité qui caractérise les variations intrajournalières des rendements obligataires pour repérer les chocs. Ils constatent que les marchés des obligations d’État de la zone euro sont fortement intégrés avant la crise, mais connaissent une importante fragmentation à partir de 2010. On remarque, au plus fort de la crise, une ruée vers les titres de qualité, qui diminue sensiblement après l’annonce du lancement du programme d’opérations monétaires sur titres (OMT) de la Banque centrale européenne (BCE) en 2012. Par ailleurs, le lien d’interdépendance entre l’Italie et l’Espagne se resserre à la suite de cette annonce, ce qui représente le seul cas avéré de contagion dans l’étude. Un tel résultat porte à croire que les pays de la zone euro ont été bien protégés les uns des autres. D’autre part, l’Italie et l’Espagne ont tiré avantage de la diminution conjointe des rendements dans le sillage de la création du programme d’OMT. Cependant, le niveau élevé de fragmentation à l’heure actuelle met les décideurs publics à rude épreuve, en ce qu’il induit une transmission inégale de la politique monétaire de la BCE dans les différents pays.
$SU(2)/Z_2$ symmetry of the BKT transition and twisted boundary conditio n

description: Berezinskii-Kosterlitz-Thouless (BKT) transition, the transition of the 2D sine-Gordon model, plays an important role in the low dimensional physics. We relate the operator content of the BKT transition to that of the SU(2) Wess-Zumino-Witten model, using twisted boundary conditions. With this method, in order to determine the BKT critical point, we can use the level crossing of the lower excitations than the periodic boundary case, thus the convergence to the transition point is highly improved. Then we verify the efficiency of this method by applying to the S=1,2 spin chains.

Quarkonium dissociation in perturbative QCD

description: For weakly bound quarkonia, we rederive the next-to-leading order cross sections of quarkonium dissociation by partons that include the hard thermal loop (HTL) resummation. Our results calculated with an effective vertex from the Bethe-Salpeter amplitude reduce to those obtained by potential nonrelativistic QCD (pNRQCD) in the relevant kinematical limit, and they can be used in a wide temperature range applicable to heavy quark systems in heavy ion collisions. Based on the lattice computation of the temperature-dependent binding energy, our numerical analysis on $Υ(1S)$ indicates that at high temperature the dominant mechanism for quarkonium dissociation is inelastic parton scattering as expected in the quasifree approximation, while it is the gluo-dissociation at low temperature. By comparing with the momentum diffusion coefficient of a heavy quark, we discuss possible O(g) corrections to the next-to-leading order thermal width.
