Divergent Forest Cover Changes Dominate Inter‐Model Spread in Near‐Surface Wind Speed Trends Over China

Abstract Near‐surface wind speed (NSWS) regulates the intensity of land‐atmosphere fluxes and the viability of wind energy systems, playing a pivotal role in human adaptation to climate change. However, at the current stage, global climate models exhibit a wide inter‐model spread...

Experimental study of the startup and heat-transfer performance of a novel two-phase closed thermosyphon with an internal phase-separation structure

Two-phase closed thermosyphons (TPCTs) are widely used as active cooling devices in permafrost engineering. Countercurrent transport of rising gas and returning liquid through a shared flow channel can impede working-medium circulation and constrain heat-transfer performance. Thi...

Structural Relaxation Modulated Phonon‐Assisted Energy Transfer Scintillator for Simultaneous X‐Ray Imaging and Thermal Signals Visualization

ABSTRACT Abnormal overheating often leads to malfunctions in electronic components during operation. Although traditional scintillators have shown great potential in object imaging, they are often unable to capture thermal signals. In this work, a series of Tb 3+ /Eu 3+ co‐doped...

Heatwave‐Period Temperature Response Parameterizations Amplify Modeled Isoprene Emissions From Temperate Trees

Abstract Heatwaves can alter temperature responses of biogenic volatile organic compound emissions, yet these effects remain poorly constrained for temperate trees. We measured leaf‐level isoprene temperature response curves for Platanus occidentalis and Populus deltoides in cent...

Biocontrol efficacy and possible mechanism of a broad-spectrum antagonistic yeast, Pichia kluyveri NY23, screened from peach fruit via microbiome analysis

Fungus-induced postharvest diseases are the leading causes of fruit loss and waste. Meanwhile, some pathogens also produce mycotoxins, posing a grave risk to public health. Fruit epicarps harbor abundant microbiota, and shifts in these communities are tightly coupled with the occ...

Pixel‐Level Reconfigurable Pancharatnam–Berry Phase Induced by Inter‐Layer Coupling of Isotropic Metasurfaces

ABSTRACT The growing demand for dynamic electromagnetic wave control has accelerated the development of programmable metasurfaces. However, conventional approaches that rely on active components such as pin diodes, varactor diodes, and liquid crystals often suffer from limited mo...

A Biomimetic Binocular Visual System Based on β ‐Ga 2 O 3 Optoelectronic Synaptic Device for Motion Recognition

ABSTRACT With the rapid development of autonomous vehicles, robotics, and monitoring systems, the demand for having visual system capable of recognizing explicit motion information, such as motion direction, state, and speed, has increased substantially. To address this demand, b...

Astronomical spectra as language: Order-agnostic foundation model for low-SNR reconstruction and stellar parameter prediction

Large-scale spectroscopic surveys contain numerous low-SNR stellar spectra that are difficult to analyze with traditional pipelines but remain valuable for Galactic archaeology, chemical-evolution studies, and population-level stellar characterization. We propose an order-agnosti...

Spatially Controlled Imaging of Proteases in Acidic Extracellular Milieu of Lesions Using DNA‐Peptide‐PNA Hybrid Probes
