When does mental well-being matter for entrepreneurial income? The role of external objective resources from social contexts

Entrepreneurs’ mental well-being has increasingly captured the attention of both scholars and the broader public. Building on self-efficacy theory and conservation of resources (COR) theory, we examine how entrepreneurs’ mental well-being influences their income. We theorize that...

Error-Controlled Mixed-Precision Cholesky Factorization with MX Microscaling Formats

Existing tile-centric mixed-precision Cholesky factorization, as used in recent Gordon Bell campaigns, is based on a heuristic that bounds only rounding contribution while ignoring underflow when classifying tiles for different IEEE floating point precisions. Direct application t...

Association between body mass index and sarcopenia in older adults: a systematic review and dose-response meta-analysis

Sarcopenia is a common geriatric syndrome associated with adverse health outcomes in older adults. Body mass index (BMI), a simple anthropometric measure, has been associated with sarcopenia; however, the dose–response relationship between BMI and sarcopenia remains incompletely...

Quantifying and mitigating explanation drift under INT8 quantization in plant disease image classification

Abstract Deep learning image classifiers are routinely compressed to INT8 for edge deployment, yet the effect of quantization on post-hoc saliency explanations has not been quantified at scale. We define explanation drift as the systematic change in a saliency map between a full-...

Exploring Usability and Legal Practice: Insights From German Judicial Users of Digital Forensics

Digital forensics has become an integral part of modern criminal proceedings, yet its effective integration remains challenging because of increasing data volumes, evolving technologies, and complex interactions between technical and legal stakeholders. Although prior work has fo...

A decade of cannabis‐related hospital admissions in Victoria, Australia: A retrospective observational study

BACKGROUND AND AIMS: Over the past decade, there has been increased lifetime use of illicit and medical cannabis, underscoring the need to examine public health impacts. This includes reports of increased cannabis-related psychosis. In this context, this study aimed to determine...

Critical factors influencing the precise ultrasound-mediated production of lipid nanoparticles

Due to their characteristics, sonicators are widely used in the pharmaceutical and food industries for the preparation of stable suspensions and oil-in-water emulsions. Ultrasound-assisted processing enables the production of lipid nanoparticles, which are of considerable interes...

Collective phases in overdamped magnetic self-propelled spherocylinders

We study the collective dynamics of self-propelled spherocylinders carrying magnetic dipole moments in two dimensions. Magnetic interactions are modeled as two opposite monopoles ± Q separated by a distance ℓ along the particle orientation axis, an idealized dumbbell model that r...

A Survey on Rigorous Results for the Dynamics of Periodic FPU Chains

Abstract In this paper we review some analytic results on the dynamics of the FPU system. In the first part of the paper, having in mind that the FPU Hamiltonian and the Toda Hamiltonian are close to each other, we present some results on the action angle variables of the Toda sy...

In-situ synchrotron X-ray diffraction and pair distribution function analysis of clay structural evolution during calcination

This study presents an in-situ synchrotron X-ray diffraction (XRD) and pair distribution function (PDF) analysis under controlled heating conditions of three raw clays, kaolinite-bearing mixed clay (NK), montmorillonite‑carbonate-rich (NM), and illite-bearing mixed clay (NI), fro...

Data-Driven Prediction of Speech-in-Noise Performance: A Systematic Review and Meta-analysis of Machine Learning Models

PURPOSE: Difficulty understanding speech in noise (SIN) is a major determinant of communication ability and quality of life, affecting individuals with hearing loss as well as some with normal hearing. Data-driven prediction methods offer a promising approach for modeling complex...

Unpacking the Role of Financial Incentives in the Motivation and Individual Performance of Nurses in LMICs: A Scoping Review Protocol

ABSTRACT Background Health systems in low‐ and middle‐income countries (LMICs) continue to face persistent challenges related to health worker performance and quality of care, exacerbated by a global shortage of nurses. Financial incentive strategies (FIS), which include performa...

Making Large Language Models More Flexible to Changing Contingencies through Tracking Induction

Abstract Recent research has shown that large language models (LLMs) exhibit rule-based insensitivity to contingencies, a functional analog of a well-documented phenomenon in human behavior. The present study extended these findings by examining whether tracking inductions can at...

Bounty Hunter: Autonomous, Comprehensive Emulation of Multi-Faceted Adversaries

Adversary emulation is an essential procedure for cybersecurity assessments such as evaluating an organization’s security posture or facilitating structured training and research in dedicated environments. To allow for systematic and time-efficient assessments, several approaches...

Opinion Dynamics Modelling: Distinct Attraction and Repulsion Topologies Highlight Quantitative Effects of Trolling

Abstract We introduce a model of opinion dynamics based on networked nonlinear differential equations. The model combines a linear attraction with a repulsive hyperbolic tangent interaction, labelled controversialness . For low controversialness, the model displays universal cons...

Economic impact of biomarker-based aging interventions on healthcare costs and individual value

We investigate the economic impact of controlling the pace of aging through biomarker monitoring and targeted interventions. Using the DunedinPACE epigenetic clock as a measure of biological aging rate, we model how different intervention scenarios affect frailty trajectories and...

Extendability of the $$B_2$$-Arrangement

Abstract Let $$({\mathscr {A}},m)$$ ( A , m ) be a free multiarrangement, and let $${\mathscr {E}}$$ E be an extension of $$({\mathscr {A}},m)$$ ( A , m ) . It is well known that if $${\mathscr {A}}$$ A is the Coxeter arrangement of type $$A_2$$ A 2 , then a free extension of $$(...

A Spectral Clustering-Type Algorithm for the Consistent Estimation of the Hurst Distribution in Moderately High Dimensions

Abstract Scale invariance (fractality) is a prominent feature of the large-scale behavior of many stochastic systems. In this work, we construct a provably convergent and easily interpretable algorithm for the statistical identification of the Hurst distribution (in particular, t...

Approximation of Askey-Wilson roots

This note presents a fixed-point formula designed to approximate the roots of Askey-Wilson polynomials for small parameter values.

A comparative evaluation of Bayesian model-assisted two-stage designs for Phase I/II clinical trials

The primary goal of a two-stage Phase I/II trial is to identify the optimal dose for the following large-scale Phase III trial. Conventional Phase I designs focus on the maximum tolerated dose (MTD), assuming that efficacy increases monotonically with dose. However, this assumpti...
