Dual‐Response Photoluminescence of Halide Double Perovskite for Novel Self‐Calibrating Thermometers, Multicolor Anti‐Counterfeiting and White LED

ABSTRACT Lead‐free halide double perovskites (LHDPs) as potentially luminescent materials are gaining recognition owing to their multi‐stimuli responsive and tunable spectra. However, the current single functionality and luminescence mode limit further application and development...

Integrated dataset of atmospheric bioaerosols over east Asia

Abstract. Bioaerosols are one of the main types of aerosols originating from the Earth's biosphere and are widely found in the atmosphere. They possess both biological attributes and aerosol characteristics, thereby exerting significant influences on climate, the environment, eco...

Charge transport, not interaction range, bounds the Lieb-Schultz-Mattis twist cost

Geometric interaction range can overestimate the energy cost of a Lieb-Schultz-Mattis twist. We prove that, under the stated assumptions, every sufficiently large admitted periodic ring with L>3R has an explicit O(1/L) upper bound on its full spectral gap. The bound is governed b...

Mitochondria-targeted therapy: a promising treatment strategy for intervertebral disc degeneration

Low back pain (LBP) is a prevalent musculoskeletal disorder worldwide, and intervertebral disc degeneration (IDD) constitutes its primary etiological factor. With the continuous advancement of research, an increasing number of studies have demonstrated that mitochondrial dysfunct...

Age-related shifts of dissolved hydrogen and its impact on rumen fermentation dynamics and microbial communities in goats (Capra hircus)

Abstract The rumen is a complex anaerobic fermentation ecosystem in which microbial communities undergo dynamic changes during host development, influencing fermentation efficiency, hydrogen utilization, and methane (CH₄) production. However, how rumen maturation reshapes hydroge...

Machine Learning–Based Cytokine Endotyping of Thyroid Eye Disease

Purpose: Thyroid eye disease (TED) exhibits profound phenotypic heterogeneity that conventional binary thyrotropin receptor antibody fails to capture. We aimed to deconstruct this heterogeneity by establishing a cytokine-derived molecular taxonomy. Methods: We profiled 102 plasma...

Fungal necromass dominates soil organic carbon accrual after decadal active restoration of alpine grassland

Active (seeding native grasses) and passive (natural recovery via degradation factor removal) restoration practices regulate soil organic carbon (SOC) recovery in degraded grasslands through distinct mechanisms. We quantified microbial- (amino sugars) and plant-derived (lignin ph...

Ultralow‐Dose Direct Photopatterning of Metal–Organic Frameworks for Scalable Device Integration

ABSTRACT The integration of metal–organic frameworks (MOFs) into microelectronic and optoelectronic devices requires patterning strategies that combine high sensitivity, structural preservation, and compatibility with scalable fabrication. Direct optical patterning offers a photo...

Unveiling the link between extreme precipitation events and flood disasters in China: from a 3D perspective

Abstract. Extreme precipitation events and their triggered flood disasters have received increasing attention owing to their severe threats to human lives and socioeconomic development. However, there is still a lack of research on their evolutionary characteristics and driving f...

The 2024 cascading glacial lake outburst flood in the Thame Valley of Everest region, Nepal: process, impacts and implications

Abstract. On the afternoon of 16 August 2024, a catastrophic flood devastated Thame Village in the Everest region of Nepal. This event resulted from a cascading glacial lake outburst flood (GLOF), where the outburst of an upstream glacial lake triggered the failure of a downstrea...

Significant Latitude‐Dependent Sensitivity of Cloud Vertical Distribution to Surface Temperature Anomalies

Abstract Changes in the vertical distributions of cloud fraction (CF) and cloud phase (CP) are robust signatures of climate change and directly influence atmospheric heating rates, planetary energy budget and hydrological cycle. However, the global sensitivities of CF and CP prof...

Optimal timing of endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy in the management of cholecystocholedocholithiasis: a multicenter retrospective analysis

To compare the clinical outcomes of ERCP combined with laparoscopic LC using both one-step and two-step approaches for the treatment of cholecystocholedocholithiasis, and to investigate the optimal timing for performing LC within two weeks after ERCP. The clinical data of 520 pat...

Reconfiguration of rural social-spatial network by mobile social platform and its impact on apple farmer livelihoods: a case study of Li County, China

Abstract Digital transformation is profoundly reshaping rural socio-economic landscapes and livelihood trajectories worldwide. However, the spatially differentiated mechanisms through which specific mobile social platforms reconfigure farmers’ social-spatial networks and the cons...

A Subtle Atmospheric Shift Is Redefining Winter Hydrology on the Tibetan Plateau

Abstract Winter climate over the Tibetan Plateau has long been characterized by cold conditions that preserve snow and regulate downstream water supply through delayed melt. Here we show that this buffering function is weakening in the Sanjiangyuan region due to a shift in winter...

Recent Advances of Metal–Organic Frameworks‐Based Sensors for Food Safety and Environmental Monitoring

Metal‐organic frameworks (MOFs) are versatile porous materials increasingly used in sensing for food safety and environmental monitoring, where on‐site detection is critical. Compared to traditional methods, MOF‐based sensors offer higher surface areas, tunable pores, abundant ac...

Mechanistic Insights Into Anionic Doping in O3‑Type Na(NiFeMn) 1/3 O 2 Cathode

ABSTRACT The lack of mechanistic guidelines hinders rational anionic doping in layered oxide cathodes for sodium‐ion batteries (SIBs). Using O3‐type Na(NiFeMn) 1/3 O 2 as a model and combining experiments with density functional theory (DFT) calculations, we reveal that doping ef...

Structural integrity facilitates multi-layer modulation of the brain-metabolome-microbiota network by Lilium lancifolium-derived vesicles in depression

Plant-derived vesicles (PDVs) have emerged as promising natural nanotherapeutics with multi-component cargo profiles and potential biological activity. However, their delivery behavior and mechanisms of action, particularly in complex neuro-immune-metabolic disorders such as depr...

Younger Dryas Glacial Advances on the Tibetan Plateau

The Younger Dryas (YD) terminated the last glaciation and initiated the Holocene, which was accompanied by widespread glacial advances. Traditional scaling models, production rates, and outlier screening approaches for 10Be exposure dating often yield inconsistent formation ages...

Quantifying the Effects of Aerosol Size Distribution on Variations in Single Scattering Albedo

Abstract Aerosol optical properties, closely linked to complex physicochemical processes, critically influence climate and environmental impacts. However, quantitative links between particle size and the changing of scattering and absorption remain insufficiently constrained. Usi...

Quasinormal modes of a charged spherically symmetric black hole in bumblebee gravity

Abstract Lorentz symmetry may be violated at the Planck scale. In the bumblebee model, a vector field acquires a nonzero vacuum expectation value, spontaneously breaking Lorentz symmetry. We study quasinormal modes of a charged spherically symmetric black hole in this framework,...
