Inflammatory Hot Phases in Arrhythmogenic Cardiomyopathy

Arrhythmogenic cardiomyopathy (ACM) has traditionally been conceptualized as a progressive inherited cardiomyopathy characterized by fibrofatty replacement and ventricular arrhythmias. Emerging clinical and translational evidence suggests that selected patients experience episodi...

Strontium Varied Across the City: 87 Sr/ 86 Sr Values at Ur (Tell al-Muqayyar, Iraq)

Analyses of isotope ratios provide researchers with evidence of past and present environments, ecologies, diets and more. For isotope analyses to be maximally effective, however, multiple forms of baseline knowledge need to be gathered. This paper contributes to filling key gaps...

Sample-Efficient Robot Skill Learning for Construction Tasks: Benchmarking Hierarchical Reinforcement Learning and Vision-Language-Action Model

Abstract This study evaluates two leading approaches for teaching construction robots new skills to understand their applicability for construction automation: a vision-language-action (VLA) model and reinforcement learning (RL) methods. The goal is to understand task performance...

A Survey of Distributed Asynchronous Many-Task Models and Their Applications

Asynchronous many-task (AMT) runtime systems have become an important paradigm for expressing fine-grained parallelism and managing asynchrony in high-performance computing (HPC). Originating from early dataflow concepts, AMTs have evolved to enable dynamic task generation, expli...

Thermodynamics of the Heisenberg XXX chain with negative spin

A bstract We study the thermodynamics of the isotropic Heisenberg XXX spin chain with negative spin, focusing on the case s = –1. The model is equivalent to the quantum lattice nonlinear Schrödinger (NLS) model and appears as an effective theory in deep inelastic scattering in hi...

Using Lattice-Based Structures to Enhance Collision Safety between Humans and Fixed-Wing UAVs

Abstract The increasing potential of accidents caused by unmanned aerial vehicles (UAVs) over recent years has imposed a new demand to enhance safety. Although many control algorithms exist to avoid collision, these methods have a dependence on electronic devices detecting a pote...

The Reverse Calcification Technique (RCT): A Quantitative Parametric Model of Aortic Stenosis Progression

Abstract Introduction Aortic stenosis (AS) develops from calcific aortic valve disease (CAVD), which narrows the aortic valve opening as leaflet stiffness increases due to calcium deposition. This study extends the Reverse Calcification Technique (RCT) by incorporating a time dim...

“I Was Determined to Take Control of My Own Body”: Self‐Managed Abortion in the US Appalachian Region

ABSTRACT Background Many people living along the Appalachian mountain region, which spread down the eastern side of the United States, experience limited access to abortion care and report high levels of distrust in health care providers. Therefore, Appalachians are likely to hav...

Efficient Computationof Physical Charging Free Energiesfor Monatomic Ions at Any Charge along Alchemical Charging Pathways

Abstract One way to compute solvation free energies is through standard alchemical free energy (AFE) methods. But they can be expensive, and they do not give useful atomwise or site-specific decompositions. Alternatively, these challenges are partly addressed by bottom-up methods...

Developmentof a FRET-Based Assay for Human NeutralSphingomyelinase 2

Abstract Neutral sphingomyelinase 2 (nSMase2) is a membrane-bound enzyme that hydrolyzes sphingomyelin (SM) into ceramide and phosphocholine. By generating the bioactive lipid ceramide, nSMase2 plays a critical role in cell stress responses and in regulating exosomes that package...

Delay Information Sharing in Two-Sided On-Demand Platforms

Problem Definition: We study delay information disclosure policies for on-demand platforms serving two user classes (customers and providers) who seek matches using the platform. The platform's objective is to maximize the match rate by choosing the level of information—no inform...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...

Adapting Architecture: Lipid Membrane Remodeling in Mycobacteria

The mycobacterial cell envelope is a formidable barrier, regarded as one of the most chemically and structurally elaborate architectures in the Bacteria kingdom. Membrane remodeling, defined as changes in membrane lipid composition in response to stressors, has been a subject of...

ElectrocatalyticHydrogenation with NanoparticlesDerived from a Cobalt Metal–Organic Framework

Abstract Electrocatalytic hydrogenation (e -H) provides a sustainable route for converting unsaturated organic substrates under mild conditions using renewable electricity as the driving force. Here, we report an MOF-derived cobalt catalyst for the e -H of acetone and pyridine. A...

Circumventing thermodynamic limitations in converting carbon dioxide into carbon nanotubes via tandem catalysis

Carbon nanotubes (CNTs) are important materials for electronics and structural composites, but their production still relies on hydrocarbon-based chemical vapor deposition, an energy-intensive and fossil-dependent process, limited by rapid catalyst deactivation. Using CO 2 as a c...

A continuous-time approach to short-term activity-cognition dynamics.

= 44.67, 92% non-White). Replicating the older adult findings, moments dominated by passive activities showed beneficial within-person cross-effects on subsequent processing speed, alongside negatively correlated random fluctuations. In contrast, between-person associations indic...

Plants, soil, and coexistence: an alternative approach to modelling plant-soil feedback

Abstract Background and Aims Plant-soil feedback (PSF) affects plant coexistence and diversity. Although the current paradigm provides a direct experimental method to quantify PSF and explains coexistence with varying levels of success, the emphasis on pairwise interactions hinde...

How well can off-the-shelf LLMs elucidate molecular structures from mass spectra using chain-of-thought reasoning?

Mass spectrometry (MS) is a powerful analytical technique for identifying small molecules, yet determining complete molecular structures directly from tandem mass spectra (MS/MS) remains a long-standing challenge due to complex fragmentation patterns and the vast diversity of che...
