Energy‐Flux‐Weighted Absorption Designed Metallic Gratings Enable Polarization‐Sensitive Perovskite Photodiodes at the O‐Band Wavelength

ABSTRACT Polarization‐sensitive photodetectors operating in the O‐band spectrum are essential for advanced optoelectronic applications. However, mostly metal halide perovskite photodetectors lack intrinsic polarization sensitivity and are typically limited to the UV–vis spectrum...

Reconfigurable phase in manganese nitride thin films by nitrogen stoichiometry

Transition-metal nitrides exhibit excellent electrical conductivity, chemical stability, and diverse physical properties, making them promising for GaN-based semiconductors, quantum bits, and spintronic applications. However, precise and reversible control of nitrogen stoichiomet...

Silicon-carbon anodes for solid‑state batteries: Challenges, optimization strategies, and future perspectives

Abstract Developing safe, high‑energy‑density energy storage systems is a central goal in electrochemistry. Silicon (Si) delivers a high theoretical specific capacity of 4200 mAh g-1, yet it suffers from severe volume expansion and interfacial degradation. Solid-state electrolyte...

Internal Resonance Mismatch‐Controlled Dissipative Bistability Collapse in Coupled Micromechanical Oscillators

ABSTRACT Nonlinear resonance governs the stability boundaries of high‐Q micromechanical systems, but the collapse of Duffing bistability is usually limited by fixed intrinsic dissipation. Here we demonstrate internal resonance mismatch‐controlled dissipative bistability collapse...

Recent progress on airway basal stem cells in chronic respiratory diseases

Airway basal stem cells (ABSCs), as tissue-resident adult stem cells within the pulmonary epithelium, possess potent self-renewal and multilineage differentiation capacities. They not only serve as the cornerstone for maintaining airway epithelial homeostasis and mediating injury...

Acetylated KLF5 as a therapeutic target mediating the anti-metastatic effects of doxycycline and methacycline in prostate cancer bone metastasis

Bone metastasis is a common and lethal complication of breast, prostate, and lung cancers. TGF-β in the bone microenvironment is pivotal for metastatic progression. We previously demonstrated that TGF-β induces acetylation of KLF5 at K369 and that acetylated KLF5 (Ac-KLF5) drives...

Efficacy and Safety Assessment of Upadacitinib for SAPHO Syndrome: A Retrospective Study of 35 Patients

OBJECTIVE: This study aimed to evaluate the efficacy and safety of upadacitinib administered over a short-term period in patients with SAPHO syndrome. METHODS: In this 12-week retrospective observational study, eligible SAPHO syndrome patients diagnosed within the past year and t...

Contrasting nighttime heterogeneous and daytime photochemical aging drive the optical evolution of black carbon

Abstract. Black carbon (BC) particles play a critical role in the climate system, yet their atmospheric aging processes and consequent optical impacts in real-world atmospheres remain insufficiently understood. In this study, we present integrated single-particle measurements usi...

Functional characterization of a pore‐forming effector TseMt from the H4 type VI secretion system of Pseudomonas aeruginosa

Abstract Pseudomonas aeruginosa is a major nosocomial pathogen in which the type VI secretion system (T6SS) contributes to interbacterial competition and virulence. While most strains encode three T6SSs, additional T6SS clusters have been identified in clinical isolates through c...

Projected westward advance of tropospheric formaldehyde over China

Economic development and population aggregation are driving the east-to-west spread of tropospheric formaldehyde (HCHO) in China; yet the historical trajectory and future threat of this westward migration remain poorly understood. Here, we analyze OMI satellite observations utili...

Observation of Antichiral Hinge States in a Three-dimensional Gyromagnetic Photonic Crystal

Abstract Recent advances in topological physics have revealed a counterintuitive class of antichiral edge and surface states that propagate in the same direction along spatially separated parallel boundaries. To date, however, experimental realizations of antichiral states have b...

A conserved small RNA-generating gene cluster undergoes sequence diversification and contributes to plant immunity

Abstract Small RNA-mediated gene silencing contributes to plant immunity. The secondary small interfering RNA (siRNA) pathway promotes defense by silencing target genes in invading fungal and oomycete pathogens. Many secondary siRNAs are derived from transcripts potentially encod...

Seismic Radial Anisotropy of the Southern Tibetan Rifts From Ambient Noise Adjoint Tomography: Basal Shear and Localized Crustal Weak Zones Promote Rifting

Abstract North–south‐trending rifts in southern Tibet record E–W extension within the Tibetan Plateau, closely linked to high gravitational potential energy from collisional thickening and northward underthrusting of the Indian lower crust. To reveal how basal shear is transmitte...

Papillary urothelial neoplasm of low malignant potential: real-world diagnostic pitfalls and clinical outcomes from a case series

Papillary urothelial neoplasm of low malignant potential (PUNLMP) is an uncommon non-muscle-invasive bladder tumor. Its indolent nature often leads to underestimation of diagnostic complexity and recurrence risk, particularly in real-world practice where pathological distinction...

Impact of Physico-Chemical Heterogeneity on the Reactive Transport Processes of Chromium (VI) in the Porous Medium

The reactive transport of hexavalent chromium (Cr(VI)) in anthropogenically disturbed sites (e.g., mine waste rock dumps, chromium salt industrial sites) is critically influenced by physico-chemical heterogeneity, yet the interplay between physical and chemical heterogeneities re...

Decadal surge of water-surface solar in China's Yangtze Delta: A high-fidelity SAR-optical fusion inventory (2015–2024)

Abstract. China hosts approximately 97 % of the world's water-surface photovoltaics (WPV), with nearly two-thirds of its national capacity concentrated in the Yangtze River Delta (YRD), a densely populated economic powerhouse facing intense land-energy trade-offs. Despite this do...

Fe 3 d Electron Delocalization in Asymmetric Fe Single Atoms Enables Nonradical Peroxymonosulfate Activation for Micropollutant Degradation

Nonradical peroxymonosulfate (PMS) activation provides a selective route for micropollutant degradation, yet the orbital-level origin of oxidant speciation at single-atom sites remains unclear. Herein, an asymmetric Fe single-atom catalyst (Fe-N3-VN-C) is synthesized via molten-s...

Integrated proteomic and metabolomic analysis identifies complement activation and metabolic alterations in the serum of patients with idiopathic membranous nephropathy: an exploratory study

Idiopathic membranous nephropathy (IMN) is a common cause of nephrotic syndrome in adults, yet its pathogenesis remains incompletely understood. This exploratory study aimed to characterize serum molecular profiles in IMN patients by integrating proteomics and metabolomics analys...

ZCCHC4 promotes replication-dependent histone mRNA translation through interaction with the eIF3 complex

Abstract Histone synthesis is tightly coupled with DNA replication to ensure proper chromatin assembly and genome stability. To meet the sharply elevated demand for histones during S phase, eukaryotic cells employ specialized mechanisms to translate replication-dependent (RD) his...
