Interplay of Lattice Distortion and Cation Disorder Governs Li-Ion Transport in Cation-Disordered Rocksalt Cathodes

Abstract Cation-disordered solids provide a chemically complex landscape in which local environments, lattice responses, and configurational disorder collectively influence ion transport. In cation-disordered rocksalt cathodes, Li+ diffusion has traditionally been interpreted usi...

Four Special Directions in AG(2,13): The 52-Point Obstruction and the Sharp Minimum

We prove that no 52-point subset of the affine plane over the field with 13 elements has exactly four special directions, where a direction is special when its thirteen parallel affine lines do not all meet the set in the same number of points. A universal incidence identity and...

A durably colonising engineered native symbiont enables sustained intestinal delivery for metabolic dysfunction and colitis

Background Engineered bacterial therapeutics represent a promising strategy for sustained intestinal delivery of therapeutic molecules, but their efficacy is limited by inefficient colonisation, safety concerns and the need for repeated administration or auxiliary delivery system...

NBS ‐Mediated Mitsunobu Glycosylation: Facile Assembly of N ‐Glycosides from Unprotected Sugars and Application to Polysaccharide Analysis

Comprehensive Summary Chemical N ‐glycosylation is a crucial step in the synthesis of complex N ‐glycosides, particularly nucleosides. However, traditional carbohydrate chemistry often relies heavily on protecting groups, which can lead to cumbersome, time‐consuming substrate pre...

Studying Physical–Virtual Hybridisation in Everyday Life Through the Time‐Geographic Project Concept

Abstract This study proposes a time‐geographic approach for operationally defining and quantitatively measuring the physical–virtual hybridisation of daily activities. While hybridisation has been proposed to move beyond separating the usage of information and communications tech...

Association of F11 Gene Variants With Cardiovascular Events and Cardiac Function

Background FXI (Factor XI) inhibitors have emerged as a promising antithrombotic strategy. However, a recent study linked decreased FXI levels with increased risk of heart failure (HF) and atrial fibrillation (AF), particularly in older adults. This study aims to investigate the...

Onvansertib-mediated PLK1 inhibition impairs spermatogenesis in the murine testis

Onvansertib (ONV) is a selective inhibitor of polo-like kinase 1 (PLK1) and has promise in treating cancer. However, its potential effects on male reproductive function remain insufficiently characterized. In this study, male mice received clinically relevant doses of ONV by intr...

Positive formulas for q-Zeta numerators of Ferrers-cell posets

We establish explicit positive formulas for Chapoton's q-Zeta numerators of Ferrers-cell posets F_b = {(i,c): 1 <= i <= r, i <= c <= b_i}, for every integer r >= 1 and every boundary sequence b_1 >= ... >= b_r >= r, together with formulas for every interval of their minimum-augme...

Machine-Learning Prediction of Carrier Mobility and Polarity Type of Polymer Semiconductors: from High-Fidelity Data to Experimental Realization

Abstract Machine learning has rapidly advanced the discovery of functional materials. However, its application to polymer-based organic field-effect transistors (OFETs) remains limited by the scarcity of high-fidelity databases and the complex structure-process-property couplings...

Association between endometriosis and cardiovascular disease: a population-based cohort study

Background: The relationship between endometriosis and cardiovascular disease (CVD) risk remains unclear. This study aimed to evaluate the association between endometriosis and CVD risk, to examine whether the association was affected by age group, and to exploratorily assess the...

Sex-specific effects of early-life arsenic exposure on body weight, arsenic metabolism, and gut microbiome stability in C57BL/6J mice

Arsenic exposure in early-life is strongly linked to health risks for mothers and their offspring. Although the mechanisms by which arsenic induces the toxicity and health impacts remain unclear, the gut microbiome makes key contributions to the metabolism of arsenic. This study...

Urban electricity demand in response to price surges: Evidence from three U.S. cities

Urban electricity systems are increasingly exposed to volatile energy prices, yet the behavioral response of consumers to extreme price shocks remains poorly quantified. The historic surge in electricity prices in many world cities from late 2022 to early 2023 provides a unique o...

Decoding fat-driven appetite: implications for flavor science and health-oriented food design

Fat perception engages overlapping neurobiological pathways—spanning taste, texture, and gut–brain signaling—that encode reward, incentive salience, and energy-balance feedback. In obesity, these circuits become dysregulated, amplifying maladaptive eating. Deciphering these mecha...

Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion

Abstract We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using JWST near-infrared (NIR) imaging and ALMA H13CO+(1–0) observations. The JWST images uncover a compact (∼0.5 pc) hub-filament system (HFS), comprising a dense central hub connected b...

The prognostic value of resistin in patients with sepsis: a systematic review and meta-analysis

Sepsis remains a leading cause of mortality worldwide. Resistin, a pro-inflammatory cytokine secreted by monocytes and macrophages, has emerged as a potential biomarker of sepsis severity and prognosis. We systematically searched PubMed, EMBASE, Web of Science, and the Cochrane L...

Scalarization of Einstein–Euler–Heisenberg black hole with multiple horizons

Abstract Scalarizations of the Einstein–Euler–Heisenberg (EEH) black hole (EEHBH) with multiple horizons are investigated in the EEH-scalar theory by introducing a quadratic scalar coupling to the Maxwell term. For mass $$M=1$$ M = 1 and Euler–Heisenberg parameter $$\mu =0.03$$ μ...

Association between sarcopenia and hypertension: results from large databases in China and the United States

Sarcopenia and hypertension are prevalent conditions with substantial public health implications. However, whether their association is consistent across different populations remains unclear. This study aimed to investigate the association between sarcopenia and hypertension usi...

Gas transport modeling and disturbance-suppression strategy during vacuum depressurization of lunar regolith simulant

Ground-based vacuum tests of lunar-regolith-related systems require granular simulant beds to be depressurized without disturbing the sample or contaminating the vacuum chamber. Delayed pore-gas release may generate transient internal–external pressure differences and induce part...

Physics-guided diffusion models for inverse design of disordered metamaterials

Disordered metamaterials are promising for programming physical properties, yet their inverse design remains challenging due to the non-intuitive structure-property relationships. Recent generative approaches, particularly diffusion models, have shown potential in high-dimensiona...

A CsWRKY46-CsPBL9-CsARI1 tripartite regulatory module coordinates H2O2 production and callose deposition in citrus fruit immunity

Plant immunity against pathogens involves multiple immune responses and intricate regulatory networks. However, how immune networks are deployed in fruit remains poorly understood. Here, we show that citrus fruit immune responses, including hydrogen peroxide (H 2 O 2 ) production...
