Organizational dynamics of memory across days.

When individuals repeatedly study and recall information across multiple learning trials their responses exhibit increasing levels of subjective organization. Whereas classic studies investigated the evolution of organization across lists within the short-time span of a single se...

Cardinalities of Irredundant Bases of Finite Primitive Groups

Let [Formula: see text] be a finite permutation group acting on a set [Formula: see text]. An ordered sequence [Formula: see text] of elements of [Formula: see text] is an irredundant base for [Formula: see text] if the pointwise stabilizer of the sequence is trivial and no point...

Global propagation of analyticity and unique continuation for semilinear waves

In this article, we develop a new method to prove both global propagation of analyticity and unique continuation in finite time for solutions of semilinear wave-type equations with analytic nonlinearity. It combines control theory techniques and Galerkin approximation, inspired b...

Moves for Bergman Algebras

We define Bergman presentations and Bergman algebras associated to Bergman presentations. These algebras embrace various generalisations of Leavitt path algebras. A Bergman presentation can be visualised by a Bergman graph, which is a finite bicoloured hypergraph satisfying two c...

CollaFuse: Collaborative Diffusion Models

In the landscape of generative artificial intelligence, diffusion-based models have emerged as a promising method for generating synthetic images. However, the application of diffusion models poses numerous challenges, particularly concerning data availability, computational requ...

Attraction to water and polarization in dragonflies and damselflies along a light pollution gradient

Abstract Aquatic insects, like odonates, rely on polarized light as a visual cue to locate water bodies for reproduction. However, artificial polarization from light pollution can lead them into ecological traps. This study investigates odonate preference for polarized light cues...

Estimating the Number of Components in Finite Mixture Models via Variational Approximation

This work introduces a new method for selecting the number of components in finite mixture models (FMMs) using variational Bayes, inspired by the large-sample properties of the Evidence Lower Bound (ELBO) derived from mean-field (MF) variational approximation. Specifically, we es...

The Small Finitistic Dimensions of Commutative Rings, II

The small finitistic dimension [Formula: see text] of a ring [Formula: see text] is defined as the supremum of the projective dimensions of [Formula: see text]-modules with finite projective resolutions. We investigate the small finitistic dimensions of four types of ring constru...

On quasi-homomorphism rigidity for lattices in simple algebraic groups

Property (TTT) was introduced by Ozawa as a strengthening of Kazhdan’s property (T) and Burger and Monod’s property (TT) . In this paper, we improve Ozawa’s result by showing that any simple algebraic group of rank \geq 2 over a local field has property (TTT) . We also show that...

Agricultural Factor Misallocation and Land Rentals in Vietnam

ABSTRACT This paper investigates factor misallocation in Vietnam's cropping sector and its connection to land rental markets. It differentiates between market‐based transactions (i.e., those involving compensation) and nonmarket transfers (i.e., those conducted without payment, o...

The center of the asymptotic Hecke category and unipotent character sheaves

In 2015, Lusztig [Bull. Inst. Math. Acad. Sin. (N.S.)10(2015), pp. 1–72] showed that for a connected reductive group over an algebraic closure of a finite field the associated (geometric) Hecke category admits a truncation in a two-sided Kazhdan–Lusztig cell, making it a categori...

Disintermediation Governance and Complementor Innovation: An Empirical Look at Amazon.com

This study investigates how the platform’s disintermediation governance policy (i.e., the policy that disciplines complementors and consumers circumventing the platform to transact directly) affects complementors’ product innovation and launching strategies. We leverage a change...

Polygenic score for sleep duration in relation to the risk of Alzheimer’s disease: results from the UK biobank

Abstract INTRODUCTION Studies have suggested sleep duration may be associated with Alzheimer’s disease risk, but findings based on self-reported sleep duration are likely to be influenced by reverse causation and residual confounding bias. METHODS A polygenic score (PGS) for devi...

Functional Quantum Field Theory in Phase Space

The formulation of Quantum Field Theory (QFT) in phase space offers a unique alternative to operator and path-integral paradigms, providing distinct conceptual advantages for semiclassical expansions. In this work, we present a systematic and self-consistent functional framework...

Use of Cue Sheets in Audio Digitization

Audio digitization is becoming essential to many libraries. As more and more audio files are being digitally preserved, the workflows for handling those digital objects need to be examined to ensure efficiency. In some instances, files are being manually manipulated when it would...

Beyond a Question of Markus Linckelmann

In the 2002 Durham Symposium, Markus Linckelmann conjectured the existence of a regular central [Formula: see text]-extension of the full subcategory over the selfcentralizing Brauer pairs of the Frobenius [Formula: see text]-category [Formula: see text] associated with a block [...

En torno a la singladura filosófica y fenomenológica de Marc Richir

Este artículo traza a grandes rasgos el itinerario intelectual de Marc Richir y termina aclarando algunos de sus conceptos fundamentales. En primer lugar se hace alusión a las actividades científicas de Richir, fundamentalmente a su actividad de físico. Tras su actividad investig...

The Frostyverse: Discrete-Grid Candidate for Gravitational Photon Deflection, Shapiro Delay, and Redshift

The Frostyverse is a speculative discrete mechanical model in which propagation, deformation, and local interaction occur through a three-dimensional elastic grid rather than a continuous spacetime metric. This preprint tests a frozen Frostyverse gravity-family candidate against...

Exact Certificates for the First Two Cases Not Covered by Steinberger's Cyclotomic Minimum-Degree Theorem

Steinberger's cyclotomic minimum-degree theorem leaves 46189 and 96577 as the first two uncovered parameters. This preprint proves the conjectured minimum degree and unique monic nonnegative-real minimizer for both values using exact integer separation certificates in a CRT tenso...
