Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1

Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

Ice-ray pentagonal packing of pseudo-fivefold helices

While fivefold point symmetry is common in nature, fivefold spatial symmetry is seldom observed. Regular pentagons cannot tile a plane without leaving voids, and even the densest “ice-ray” packing is exceptionally rare. Fivefold helices are equally elusive. We report a small mole...

The anatomy of hitting: assessing age-related changes in MLB performance via layered Dirichlet modeling

Abstract The productive career of a professional athlete is short relative to the human lifespan, with most Major League Baseball (MLB) players retiring by age 40. Although younger players often possess superior physical tools, older players may differ in the composition of plate...

Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics

The next generation of particle physics experiments will face an era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environments and operational constraints. Harnessing these data for scientific discovery demands real-time infere...

Pick Aggregator: A Multimodel Ensemble of Machine Learning Pickers to Generate an Onshore–Offshore Seismic Catalog for Puerto Rico and the Virgin Islands

Abstract Offshore seismic swarms north of Puerto Rico and the Virgin Islands remain poorly characterized due to limited azimuthal coverage from the inland Puerto Rico Seismic Network (network code PR). Here, we integrate data from six U.S. Geological Survey (USGS) ocean-bottom se...

Programming Host–Guest Interactions in Covalent Organic Frameworks with Arylazopyrazole Photoswitches

Abstract Programming host–guest interactions in porous crystalline materials using external stimuli offers a promising strategy for adaptive molecular separations but remains challenging because adsorption is often governed by pore structure rather than tunable molecular interact...

The effects of augmented reality within a mobile app for problem posing during math walks

This study explores students using Augmented Reality within the Mathfinder app to engage with math walks, with students positioned as creators of math walks content, engaging in problem-posing. In Study 1, students were randomly assigned to versions of the app that had AR tools/o...

The DESI Y1 RR Lyrae Catalog. II. The Metallicity Dependency of Pulsational Properties, the Shape of the RR Lyrae Instability Strip, and Metal Rich RR Lyrae

Abstract RR Lyrae stars (RRLs) are valuable probes of both Milky Way assembly and stellar-evolution physics. Using a sample 6240 RRLs obtained in the first year of the Dark Energy Spectroscopic Instrument (DESI) survey, we investigate the metallicity of RRLs and its correlation w...

Thermomechanical responses of an imperfectly bonded multi-layered structure resting on an elastic foundation

A new analytical model is developed for predicting responses of a multi-layered structure resting on an elastic foundation and subjected to general thermomechanical loading. The structure is composed of an arbitrary number of thin layers of dissimilar materials that are imperfect...

Performant Tridiagonal Factorization of Skew-Symmetric Matrices

Abstract. The factorization of skew-symmetric matrices is a critically understudied area of dense linear algebra, particularly in comparison to that of general and symmetric matrices. While some algorithms can be adapted from the symmetric case, the cost of algorithms can be redu...

Raman Spectroscopic Characterization of the Benzene:Acetonitrile (3:1) Cocrystal Relevant to Titan, Saturn’s Moon

Abstract Titan, Saturn’s largest moon, hosts active organic chemistry and surface environments where small molecules are expected to crystallize as molecular minerals. Benzene and acetonitrile, both predicted to be present on Titan, were shown to form a thermodynamically stable b...

Cross-Border Anti-Corruption and Critical Infrastructure Compliance Framework (CBACI) — Manual, Version 1.0

Technical manual establishing a methodological framework for cross-border anti-corruption and critical infrastructure compliance, covering third-party due diligence, FCPA-aligned risk assessment, and compliance program design for organizations operating between the United States...

Your choice, your team: psychological ownership and AI decision-making

Purpose This study examines how psychological ownership influences user satisfaction in artificial intelligence (AI)-assisted decision-making contexts within sport consumption. While prior research has focused primarily on algorithmic accuracy and outcome quality, it has paid lim...

Contesting care, navigating paradoxes: a thematic reflexive analysis of eating disorders advocates voices

Abstract Eating disorders (EDs) are a growing public health concern in the United States, yet advocacy for improved treatment and awareness remains underexplored in academic research. While advocacy movements in fields such as HIV/AIDS or breast cancer have received sustained att...

Eating escargot: seasonal terrestrial gastropod exploitation by forest foragers in the ethnoarchaeological record of Central Africa

Abstract In the prehistoric record, the presence of small-sized resources including gastropods is often viewed as a marker of increased dietary breadth, declining foraging efficiency and/or flexible subsistence patterns involving diversified foraging activities. However, research...

Spatial and Epistemic Agency When Engaging with Math Walks at a STEM Residential Camp

Math walks, where participants explore physical spaces and make connections to mathematics, have been implemented in a wide variety of ways in different learning settings. Math walks connect place-based learning, the development of interest in STEM fields, and opportunities for s...

Recognizing gender role congruity in newly appointed CEOs’ strategic risk-taking

Role congruity theory suggests that men and women are perceived according to their gendered roles and may avoid violating expectations based on those roles. However, little is known about what enables individuals to recognize these gendered expectations, particularly in difficult...

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

Abstract Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping their spatial structures are therefore crucial for understanding how large-scale environme...

A generalized supervised contrastive learning framework for integrative multi-omics prediction models

Abstract Recent technological advances have highlighted the significant impact of the human microbiome and metabolites on physiological conditions. Integrating microbiome and metabolite data has shown promise in predictive capabilities. We developed a new supervised contrastive l...
