Data-Driven Inference of Susceptibility, Correlation, and Dynamic Responses via Machine Learning

Abstract Understanding how complex systems respond to external perturbations is essential to characterize the intrinsic properties of the systems and then to control their responses. Despite some preliminary trials via either analytical modeling or numerical calculations, it is u...

An Agent Framework for Land Resource Monitoring and Analysis

This paper proposes an agent framework for land resource monitoring and analysis. The framework organizes and encapsulates domain knowledge and operational workflows into standardized skill units, enabling the agent to perform task planning, execution, and reflection under skill-...

Investigation of glacier mass balance based on multi-source observation in the Karakoram over the past 25 years

The “Karakoram Anomaly” — the atypical stability of glaciers in a warming climate—has introduced considerable uncertainty into projections of regional water resources. However, the resilience of this anomaly under sustained climate forcing remains poorly quantified. In this study...

Thermo-mechanical analysis and structural modification of the boss–liner interface in Type IV hydrogen pressure vessels

Type IV hydrogen pressure vessels rely critically on the boss–liner interface for sealing, which is challenged by coupled temperature and pressure variations. Since the localized evolution of interfacial contact behavior lacks sufficient quantitative characterization, this study...

Forest and bioenergy expansion amplifies climate warming by accelerating regional cloud loss

Abstract. Land use and land cover change (LUCC) can exacerbate cloud-mediated climate warming. However, the long-term response of cloud cover to LUCC remains underexplored, particularly regarding differences between idealized and realistic forest expansion scenarios, as well as b...

Concurrently Achieving Excellent Anti‐Thermal Quenching and Ultrahigh Light Yield in Scintillation of Hybrid Manganese Halides

ABSTRACT Simultaneously achieving high thermal stability and excellent scintillation performance in Mn‐based organic inorganic hybrid metal halide (Mn‐OIMH) scintillators remains a highly challenging task. Through the rational substitution of the monocation by asymmetric dication...

Intensifying compound drought–heatwave events weaken ecosystem water-use efficiency in the Nile River Basin

Climate warming has intensified compound drought–heatwave (CDHW) events worldwide, posing growing threats to ecosystem carbon–water dynamics. However, the impacts of CDHWs on ecosystem water-use efficiency (WUE), particularly event sequencing, drought memory, and climatic heterog...

In Situ Formation of a Hybrid Alloy‐Fluoride Interphase for Stable High‐Capacity Phosphorus Anodes

ABSTRACT Phosphorus‐based anodes are promising candidates for next‐generation high‐energy‐density lithium‐ion batteries owing to their high theoretical capacity. However, their practical application is severely limited by drastic volume variation and unstable solid electrolyte in...

Virome Diversity and Host-Associated Heterogeneity in Mosquitoes and Biting Midges Across Yunnan, China

Mosquitoes and biting midges harbor diverse viruses, but the factors shaping their viromes remain incompletely understood. We analyzed 35 pooled libraries from seven host groups across 15 locations in Yunnan, China, sampled in June 2025, using total-RNA sequencing, viral annotati...

GaSb–TFLN Hybrid Integrated Pockels Laser for Ultrafast Spectroscopy in the 2 μm Waveband

Abstract High-speed wavelength-tunable lasers in the 2 μm waveband are important for laser spectroscopy, optical communication, and frequency-modulated continuous-wave LiDAR. Here, we demonstrate a hybrid integrated Pockels laser that combines a GaSb reflective semiconductor opti...

A Developed VMD-DMD Algorithm with Machine Learning Models for Improving Sea Level Predictions: A Case Study of the Mediterranean Coastlines

Accurate prediction of sea level change in the Mediterranean Sea is essential for coastal risk management; however, the nonstationary behavior of sea level makes this difficult. This study presents a hybrid framework that integrates variational mode decomposition (VMD) and dynami...

Mode‐Selective C═C and C─N Vibrational Coupling Modulates Nonradiative Decay in Regioisomeric Organic Phosphorescent Emission

ABSTRACT Structural isomerization has emerged as an effective strategy for improving the performance of organic room‐temperature phosphorescent materials, but reported explanations are mainly attributed to differences in molecular packing, spin‐orbit coupling, excited‐state elect...

Enantioselective Synthesis of Axially Chiral Tetraphenylethenes via NHC-Catalyzed Desymmetrization and Following Kinetic Resolution

Abstract Herein, we report an efficient method for the enantioselective construction of axially chiral tetraphenylethylene (TPE) via N-heterocyclic carbene (NHC)-catalyzed desymmetrization of prochiral isophthalaldehyde-derived TPEs. Both aliphatic alcohols and phenols were well-...

Energetic near-inertial waves induced by winter storms and mesoscale eddies in the subtropical Northwestern Pacific Ocean

Abstract. Near-inertial waves (NIWs) play a fundamental role in transferring wind energy into the ocean interior and sustaining diapycnal mixing, yet their wintertime characteristics and interactions with mesoscale eddies remain insufficiently understood. Using subsurface mooring...

Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

Machine Learning Guided Broadleaf‐Inspired Reconfigurable Triboelectric Array for Space‐Efficient Ocean Current Energy Harvesting and Antifouling

ABSTRACT Ocean currents represent a stable source of blue energy. Flag‐type triboelectric nanogenerators (F‐TENGs), which have been widely investigated for harvesting energy from low‐velocity ocean currents, generally rely on bluff body to induce vortex. This dependence limits th...

A non-biomineralized trilobitomorph euarthropod (Helmetiida) with appendicular morphology from the early Cambrian Chengjiang biota, China

Abstract Helmetiida is a major group of Trilobitomorpha and Artiopoda known from Cambrian Burgess Shale-type Lagerstätten. Phylogenetic studies have suggested that they are closely related to trilobites as their possible sister taxon. With seven genera and eight species, Helmetii...

Neonatal overfeeding accelerates age-related sarcopenia and metabolic disorders through lifelong gut mucosa and microbiota programming in mice

Early-life nutrition shapes lifelong health, yet the long-term consequences of childhood overnutrition, particularly on musculoskeletal aging, remain unclear. Here, we show that neonatal overfeeding acts as a developmental insult that accelerates age-related sarcopenia in both se...
