Post-Functionalized Vinyl-Addition Polynorbornenes as Modular Platforms for Anion Exchange Membranes: Structure–Property Relationships

Abstract Fully hydrocarbon-based anion exchange membranes (AEMs) were developed through a facile post-polymerization strategy using vinyl-addition polynorbornene (VA-PNB) backbones. A high-molecular-weight poly(5-vinyl-2-norbornene) (PVNB) precursor was synthesized via chemoselec...

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...

Performance Enhancement of Solar Stills Using Wire‐Mesh Materials: A Systematic Review of Passive, Hybrid, and Active Approaches

ABSTRACT Solar still (SS) desalination is a solar‐based desalination technology that is environmentally friendly and has the potential to provide an abundant supply of saline water, but has been limited in practice due to low productivity and thermal efficiency. This systematic r...

Nonlinear Electro‐Optic Visible Photonic Circuits for Solid‐State Quantum Defects

Integrated visible photonic engines for solid-state quantum defects provide a foundation for scalable quantum networks. While miniaturization is advancing, active manipulation remains limited by the difficulty of achieving simultaneous milliwatt-scale visible light generation and...

Sex determination through metric analysis of teeth crown

Teeth that are resistant to external stimuli and have little diversity for individuals can be an important identification factor. This study aimed to present a method that can be used easily and accurately to identify individuals using their teeth, specifically to determine their...

Joint Modeling of GD-1 and C-19 as Old Streams

Abstract DESI observational data for the GD-1 and C-19 streams are compared to stream simulations in an evolving multihalo potential of a Milky Way–like galaxy based on a cosmological Milky Way–like simulation. The number of subhalos decreases with time, and the subhalo-stream en...

Three dimensional conjugate natural convection heat transfer of Mxene toluene nanofluid in a heat generating finned cubic cavity: finite element and ANN investigation

This study numerically investigates three dimensional natural convection heat transfer of an Mxene toluene nanofluid in a cubic cavity containing six internal heat generating fins using the Galerkin finite element method, motivated by the need for efficient passive thermal manage...

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...

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...

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...

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...

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...

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...

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

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
