Scenario-Based Dynamic Assessment of Rooftop Solar Photovoltaic and Heat Pump Systems for Low-Emission French Single-Family Houses

Achieving the European Union’s (EU) climate neutrality targets requires residential buildings to reduce operational carbon emissions, while increasing on-site renewable generation. However, the relative contributions of rooftop photovoltaic (PV) systems with battery storage and h...

The Composite Spectrum of QSO Absorption Line Systems in DESI DR2

Abstract We present details regarding a composite spectrum of quasar (QSO) absorption line systems. In this composite spectrum, we identify more than 70 absorption lines and observe oxygen and hydrogen emission features at a higher signal-to-noise ratio than any previous study. A...

Retail café cup preferences: evidence from global and domestic coffee brands

Purpose The rapidly expanding coffee market in an emerging economy provides the context for this study, which examines how café cup design in café retailing influences purchase intention. It compares customers of Starbucks (a global semi-luxury brand) and Luckin Coffee (a domesti...

Existence analysis of nonlinear q-fractional differential inclusions with p-Laplacian operators and an aerospace vibration-modeling illustration

This paper investigates a coupled system of nonlinear q -fractional differential inclusions involving nested p -Laplacian operators and nonlocal boundary conditions. The problem is formulated in a multivalued setting, where the nonlinear inclusion depends on the state vector and...

A zero-shot LLM framework for analyzing user preference on product attributes: a case study of smartwatch reviews

The rise of zero-shot learning through Large Language Models (LLMs) opens new opportunities for analyzing consumer feedback without relying on annotated data. This study proposes a zero-shot framework to uncover user preferences on product attributes, using 12,900 Amazon smartwat...

Molecular Mechanism of AtCAX3-Induced BPA Tolerance in Plants

Cation/H+ Exchangers (CAXs) are involved in the sequestration of cations such as Ca2+, Mn2+, Li+, Zn2+, and Cd2+ from the cytosol into the vacuole using proton gradients. Our previous studies demonstrated the involvement of AtCAX3 in Cd2+ tolerance. In this study, we investigated...

The DESI Y1 RR Lyrae Catalog. I. Empirical Modeling of the Cyclic Variation of Spectroscopic Properties and a Chemodynamical Analysis of the Outer Halo

Abstract We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6240 RRLs out to ∼120 kpc from the Galactic center and over 12,000 individual epochs with homogeneous...

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...

APC/C−CDH1 suppresses AROS-mediated protection against DNA damage-induced senescence by ubiquitination

Anaphase-promoting complex/cyclosome (APC/C) regulates the cell cycle by destruction of target proteins ubiquitination. However, understanding the control of APC/C has remained elusive. We identify APC2, the catalytic core subunit of APC/C, as a binding partner of active regulato...

Tumor subtype-specific transcriptional signatures predict recurrence risk in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) displays significant molecular heterogeneity that clinical staging alone does not fully account for when assessing the risk of recurrence following curative treatment. To address this, we developed a multi-cohort survival modeling framework that tra...

Comprehensive Thermal and Bio‐Convection Analysis of MHD Casson‐Hybrid Nanofluid Flows With Hall and Current Effects Over a Sheet

ABSTRACT Thermal energy management is a central idea in modern engineering systems such as advanced electronics and renewable uses for heat all rely on it. Hybrid nanofluids, which integrate two distinct types of nanoparticles within a base fluid, enhances their thermal propertie...

Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated CP/QD...

Bayesian 3D modeling of the orbital dynamics of wide binary stars: gravitational anomaly at low acceleration from a highest-quality sample of 36 wide binaries with accurate 3D velocities

Python modules, data files, and MCMC output figures for "Detection of Gravitational Anomaly at Low Acceleration from a Highest-quality Sample of 36 Wide Binaries with Accurate 3D Velocities" (arXiv:2601.21728, submitted to the AAS journals). [Note: Due to upload limitations, MCMC...

Uncertainty-aware ordinal deep learning for automated periapical index assessment on dental radiographs

Abstract Automated radiographic assessment of periapical health may support scalable review, but the five-grade Periapical Index (PAI) is ordinal and should not be treated as nominal classification. We present PAI-SegScore as a single-cohort framework developed on DenPAR radiogra...

A compact, wireless fluorimeter system for continuous, real-time monitoring of tissue perfusion via in vivo fluorescence signals

In vivo fluorescence signals provide physiological and pathological insights for the interpretation of biological states associated with anatomical abnormalities or disease. Conventional methods for measuring fluorescence signals rely on bulky, costly instrumentation for imaging...
