GrIT: Group Informed Transformer for Sequential Recommendation

Sequential recommender systems aim to predict a user's future interests by extracting temporal patterns from their behavioral history. Existing approaches typically employ transformer-based architectures to process long sequences of user interactions, capturing preference shifts...

Petroleum Wealth and Intergenerational Equity in Norway and Alberta

This article examines how Norway and Alberta transform petroleum wealth into an inheritance for future generations. Connecting economic history, institutional economics and narrative economics, it compares public participation, fund contributions and withdrawals, and institutiona...

Infection and transmission dynamics of bovine and human influenza A H5N1 viruses in mouse and hamster models

ABSTRACT Here we investigated the pathogenesis and contact transmission of bovine- and human-derived highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b genotype B3.13 viruses in mammalian models. Using reverse genetics, we rescued three naturally occurring viruses, rTX2...

Efficiency, Curvature, and Complexity of Quantum Evolutions for Qubits in Nonstationary Magnetic Fields

In optimal quantum-mechanical evolutions, motion can take place along paths of minimal length within an optimal time frame. Alternatively, optimal evolutions may occur along established paths without any waste of energy resources and achieving 100% speed efficiency. Unfortunately...

A human-centred design of a novel user interface that combines submarine systems and integrates augmented reality

Abstract Modern submarine control rooms are the outcome of an iterative design process, that incorporates advancing technology, increasing automation, and evolving ways of working. Novel user interfaces that address existing limitations in contemporary submarine systems is one wa...

Fermi acceleration mechanisms beyond Lorentz symmetry

Abstract We construct models for first- and second-order Fermi acceleration of particles, incorporating generic frame transformations, dispersion relations, and conservation laws. Within this framework, we study deformations of Lorentz symmetry via the $$\kappa $$ κ -Poincaré alg...

Controlling Nonadiabatic Transitions through Engineered Ultrafast Laser Fields at Conical Intersections

Abstract In this paper, we investigate the coherent control of nonadiabatic dynamics at a conical intersection (CI) using engineered ultrafast laser pulses. Within a model vibronic system, we tailor the pulse chirp and temporal profile and compute the resulting wave packet popula...

ForeSpeed: A Real-World Video Dataset of CCTV Cameras with Different Settings for Vehicle Speed Estimation

The need to estimate the speed of road vehicles has become increasingly important in the field of video forensics, particularly with the widespread deployment of CCTV cameras worldwide. Despite the development of various approaches, the accuracy of forensic speed estimation from...

Topological pressure and equilibrium state for certain correspondences

In \cite{Miller-Akin1999}, Miller and Akin investigated the invariant measures for correspondences, which are also known as upper semi-continuous set-valued maps. Recently, the variational principle and thermodynamic formalism for forward expansive correspondences were studied by...

Adaptive cut reveals multiscale complexity in networks

Abstract Hierarchical clustering and community detection are important problems in machine learning and complex network analysis. A common approach to identify clusters is to simply cut dendrograms at some threshold. However, single-level cuts are often suboptimal in terms of cap...

Sentiment analysis in rural areas: a systematic review of applications and approaches

Rural depopulation and territorial imbalances are ongoing challenges that require innovative tools for understanding community needs and informing evidence-based policy. Sentiment Analysis (SA) has emerged as a promising methodology for extracting emotional information from large...

Interplay Between Standard Quantum Detailed Balance and Thermodynamically Consistent Entropy Production

Abstract We demonstrate that, for a quantum Markovian semigroup on a finite-dimensional Hilbert space, if it satisfies the standard quantum detailed balance condition, its generator admits a special representation that yields a vanishing entropy production rate. Conversely, if th...

Mixing ventilation by in-seat air outlets for single-aisle aircraft

Abstract In recent years, alternative ventilation systems for aircraft cabins have attracted the attention of scientists and aircraft manufacturers due to their potential to save energy and increase thermal comfort. The aim of this study was to investigate whether comfortable the...

Online Disjoint Spanning Trees and Polymatroid Bases

Abstract. Finding the maximum number of disjoint spanning trees in a given graph is a well-studied problem with several applications and connections. The Tutte–Nash–Williams theorem provides a min-max relation for this problem which also extends to disjoint bases in a matroid and...

Selective sparsity–enhanced synchronization in disordered semiconductor laser networks

Biological networks tend to leverage selective sparsity as an economic strategy to optimize function while minimizing wiring costs. In contrast, achieving synchronization in engineered systems such as semiconductor laser arrays is traditionally expected to require resource-intens...

Homogenization of Non-symmetric Convolution Type Operators

The paper studies homogenization problem for a bounded in $$L_2(\mathbb {R}^d)$$ convolution type operator $${\mathbb {A}}_\varepsilon $$ , $$\varepsilon >0$$ , of the form $$\begin{aligned} ({\mathbb {A}}_\varepsilon u) ({\textbf{x}}) = \varepsilon ^{-d-2} \int _{\mathbb {R}^d}...

Analog quantum feature selection with neutral-atom quantum processors

Abstract We present a quantum-native approach to feature selection (QFS) based on analog quantum simulation with neutral-atom arrays. Feature relevance, measured through mutual information with the target variable, is encoded in site-dependent local detunings, while pairwise feat...

Ethynyl Substituents as Rheostatic Triggers in Single‐Molecule Junctions

ABSTRACT Miniaturised mechanoresistive devices, where charge transport efficiency is modulated by mechanical displacement, are an important class of electromechanical systems that promise unique sensing accuracy and sensitivity. Single‐molecule junctions have emerged recently as...

Zeros and Exponential Profiles of Polynomials I: Limit Distributions, Finite Free Convolutions and Repeated Differentiation

Abstract Given a sequence of polynomials $$(P_n)_{n \in \mathbb {N}}$$ ( P n ) n ∈ N with only nonpositive zeros, the aim of this article is to present a user-friendly approach for determining the limiting zero distribution of $$P_n$$ P n as $$\deg P_n \rightarrow \infty $$ deg P...

Asymptotic-Preserving Schemes for the Initial-Boundary Value Problem of Hyperbolic Relaxation Systems

Abstract. In this work, we present a numerical method for the initial-boundary value problem (IBVP) of first-order hyperbolic systems with source terms. The scheme directly solves the relaxation system using a relatively coarse mesh and captures the equilibrium behavior quite wel...
