Direction-aware structural and semantic alignment for SAR-optical image matching

Cross-modal image matching between synthetic aperture radar (SAR) and optical images is an essential task for applications such as change detection and scene understanding. However, it remains challenging due to significant structural distortions and semantic inconsistencies aris...

Reversible Inhibition of Ammonia Monooxygenase by 1,9-Decanediol Triggers a RegB-RegA-Associated Energy Crisis and Stress Response in Nitrosomonas europaea

Abstract 1,9-decanediol, a rice-derived biological nitrification inhibitor (BNI) suppresses soil nitrification and nitrous-oxide emissions, but the mechanisms of action against ammonia-oxidizing bacteria remain unclear. Combining physiology and transcriptomics in Nitrosomonas eur...

Grassland soil bulk density decreases under grazing exclusion and responds asymmetrically to altered precipitation

Soil structure is a key determinant of grassland health and functioning, with bulk density serving as a widely used proxy. Grazing exclusion is a common restoration practice that often reduces soil bulk density in grasslands by restoring plant productivity and removing livestock...

Endogenous Functional Group Engineering Enables High‐Efficiency Hard Carbon Anodes for Sodium‐ion Batteries

ABSTRACT Hard carbon is a leading anode for sodium‐ion batteries, but its widespread use is still prevented from low initial Coulombic efficiency (ICE) and unstable electrode‐electrolyte interfaces. In this work, we show that engineering endogenous functional groups can directly...

Plug-and-Play Dramaturge: A Divide-and-Conquer Approach for Iterative Narrative Script Refinement via Collaborative LLM Agents

Although LLMs have been widely adopted for creative content generation, a single-pass process often struggles to produce high-quality long narratives. How to effectively revise and improve long narrative scripts like scriptwriters remains a significant challenge, as it demands a...

Sliding-ferroelectric order imprinted onto excitonic and valley responses in van der Waals heterostructures

Ferroelectricity driven by interlayer sliding provides a distinct route to nonvolatile control in van der Waals (vdW) heterostructures, yet resolving stacking-dependent ferroelectric states and their local interfacial consequences remains challenging. Here, we report that bilayer...

Spatial layout planning of cable based on a hybrid method combining interference obstacle local post-insertion and improved Dubins curves

Cables in three-dimensional (3D) wall-adherent routing must simultaneously satisfy terminal direction vectors and bending curvature constraints, making forward design and precise pre-cutting a significant challenge. To address this, this paper proposes a hybrid planning method, t...

Narrowing urban heat disparities alongside faster greening in low-income neighborhoods across cities in the United States

Urban heat disproportionately burdens socioeconomically vulnerable communities, yet how these disparities change over time remains poorly understood. Here we show that heat disparities between low- and high-income neighborhoods generally narrowed across 55 major cities in the Uni...

Formation of Carbonisocyanatidic Amide in Interstellar Ice Analogs as a Candidate Precursor to Prebiotic Pyrimidines

Abstract Understanding how pyrimidine nucleobases form in space is central to prebiotic chemistry, yet the pathways assembling these heterocycles remain unresolved. Carbonisocyanatidic amide (H2NC(O)NCO), an acyclic intermediate with heteroatom connectivity relevant to uracil and...

EcoMLC: An Energy-Efficient Machine Learning Compilation Framework via Cache Reuse and Frequency Scaling

While modern machine learning compilers (MLCs) are pushing deep neural network (DNN) inference latency to its theoretical limits, the accompanying energy overhead has become a critical bottleneck for large-scale deployment. Excessive energy consumption not only increases electric...

Aggregate size regulates soil carbon priming through divergent microbial CN acquisition strategies

Soil aggregates create heterogeneous microenvironments that influence soil organic carbon (SOC) turnover and microbial communities. However, how aggregate size regulates priming effects (PE) through microbial life-history strategies and C N acquisition pathways remains unclear. W...

Let Token Draw Itself

Recent autoregressive image generation models achieve impressive results by modeling images as sequences of discrete tokens. However, these tokens are treated as opaque latent codes that are decoded jointly, making the visual contribution of each generation step invisible. We pro...

Targeting the CD4+ effector memory T cells re-expressing CD45RA suppressor galectin-7: a multi-omics-guided therapeutic strategy for idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial lung disease with limited therapeutic options. Although single-cell and spatial transcriptomics have revealed cellular heterogeneity within the IPF lung microenvironment, the immune drivers with causal rel...

Depth-dependent microbial roles and associations with soil multifunctionality along an afforestation chronosequence in a hyper-arid desert

Soil multifunctionality refers to the capacity of soil to support multiple ecosystem processes (e.g., nutrient cycling, organic matter stabilization), which is mediated by soil microorganisms. Afforestation is a pivotal strategy for combating desertification in hyper-arid regions...

Decadal Dynamics of Air Temperature on the Southern and Northern Slopes of the Kunlun Mountains, Qinghai‐Tibet Plateau, and the Topographic Modulation Effects

ABSTRACT Topographic conditions are key factors governing surface energy distribution in high‐alpine mountainous areas, determining the dynamic variations of local climate and the thermal state of permafrost, which holds profound implications for understanding global climate syst...

Urban-rural household carbon emissions and their inequality in China: From the perspective of consumption structure

Reducing household carbon emissions (HCE) and their inequality is a global concern to promote fair environmental sustainability. However, the research on analyzing this issue across urban-rural households with different consumption structures is scarce, also not holistically capt...

The Impact of Infectious Disease Severity on Stigma Associated With Affected Regions: A Facial Representation Perspective

ABSTRACT Individuals from regions affected by infectious disease outbreaks may be stigmatized because others hold negative mental images—or mental representations—of them. This study investigated whether such outbreaks lead to the formation of negative mental representations of r...

Improved estimation of lake storage variation via DEM reconstruction integrating elevation and morphological constraints

High-quality Digital Elevation Models (DEMs) are essential for accurately estimating lake storage variations, but the high cost of in-situ measurements limits their large-scale application. Reconstructing DEMs from remote sensing-derived lake contours is a promising low-cost alte...

Time-synchronization-based constant-frequency grid-forming technology for power electronics-dominated systems

With rising penetration of distributed energy resources, power systems are becoming increasingly power electronics-dominated. Constant-frequency control ensures a fixed system frequency and mitigates frequency instability risks, but existing schemes cannot intuitively and flexibl...
