Crystallographic Regulation of LIPSS Formation on Metal Surface Under Randomly Polarized Nanosecond Laser Irradiation

ABSTRACT Laser‐induced periodic surface structures (LIPSS) provide a mask‐free route for fabricating periodic micro/nanostructures. However, the directional energy modulation imposed by linear polarization can often mask crystallography‐dependent material responses, leaving the r...

Driving mechanisms of a new SVR-based trend anomaly in China’s A-share market

This paper constructs a multi-horizon trend signal using support vector regression trained on short-, medium-, and long-term moving averages to capture asynchronous trading behaviours of heterogeneous investors. Long-short portfolios sorted on the trend signal yield significant r...

Revisiting and Improving Soil Surface Resistance Schemes for Land Surface Modeling

Abstract Accurate representation of soil evaporation is critical for understanding land‐atmosphere interactions and improving climate simulations, where soil surface resistance plays a key regulatory role. However, existing schemes differ substantially and lack systematic evaluat...

Overcoming the Spin Barrier of Oxygen Redox Chemistry in Lithium–Oxygen Batteries via Metal–Support Magnetic Interaction

ABSTRACT A major bottleneck for the practical application of lithium–oxygen (Li–O 2 ) batteries is the high overpotential resulting from sluggish kinetics of oxygen redox chemistry. This kinetic limitation can rise in part from the spin‐state transition barriers in converting tri...

Mixture cure rate model with artificial neural network for interval-censored data

Mixture cure rate models represent a valuable tool to delineate the presence of a cured subgroup in the entire population under study. Among the vast literature, a popular research line is to regress the probability of an individual being cured on covariates through a parametric...

Performance Characteristics and Sensitivity Analysis of an Ammonia-Diesel Dual-Fuel Engine Under Varying Ammonia Energy Ratios and Diesel Injection Parameters

Ammonia can partially replace diesel in compression ignition engines, but the relative influences of the ammonia energy ratio (AER), pilot–main injection timing advance, and injection pressure on engine performance remain insufficiently quantified. This study evaluated these infl...

A novel sensitivity-driven multistage feedforward inverse modeling approach for source identification of organic-contaminated aquifer

In the present study, a sensitivity-driven multistage combined search system was established to improve the search capability and accuracy of inverse modeling for the simultaneous identification of DNAPL contamination sources and contaminant transport (CTR) parameters. The system...

Integration of Nascent Transcriptomes and Cross-Species Atlases Reveals Evolutionary Barriers in Transcriptional Kinetics During Mammalian Hibernation

Mammalian hibernation requires extensive metabolic remodeling, but traditional transcriptomic approaches cannot distinguish between mRNA synthesis and degradation, leaving the evolutionary barriers governing its transcriptional control unclear. To address this, we integrated nasc...

Updating thermal head of RECoverable Autonomous Sonde (RECAS) for better drilling performance in Qilin Subglacial Lake exploration

Abstract. There are numerous subglacial lakes in Antarctica, typically covered by thick ice sheets. Qilin subglacial lake is one of the largest subglacial lakes in Antarctica, lying beneath approximately 3600 m of ice. The exploration of this unique environment is of considerable...

High-Performance Near-Infrared Perovskite Single-Crystal Photodetectors Enabled by Multifunctional Additive Engineering for Image Encryption

Abstract Iodide-based metal halide perovskite single crystals are promising candidates for near-infrared photodetection because of their favorable bandgaps and outstanding optoelectronic characteristics. However, iodide oxidation during crystallization deteriorates precursor stab...

Cooperative Shunt Photocatalysis of Pt Single Atoms and Nanoparticles for Efficient Methanol Conversion to Hydrogen and Formaldehyde

ABSTRACT Photocatalytic methanol dehydrogenation requires not only charge separation but, more critically, synchronized and rapid consumption of photogenerated electrons and holes—an unmet challenge in conventional Pt‐based photocatalysts. Here we report a photocatalytic platform...

Smoking status and duration are associated with taxonomic and functional differences in the oral microbiome

Smoking is a major modifiable risk factor for human health and has been linked to alterations in the oral microbiome. However, how oral microbial composition and functional potential differ across smoking duration remains insufficiently characterized. This study aimed to evaluate...

Bioinspired Hierarchical Silica Nanoarchitecture for VOCs Discrimination through Confined-Space Optical Modulation

Abstract Optical discrimination of volatile organic compounds (VOCs) commonly relies on chemically active materials or multisensor arrays, making stable signal transduction and structural integration challenging. Here, we report a bioinspired hierarchical silica nanoarchitecture...

Sex‐Specific Digital Phenotyping of Lower Urinary Tract Symptoms: A Cross‐Sectional Study of 1586 Adults From 35 Centers in China

ABSTRACT Background and Purpose Lower urinary tract symptoms (LUTS) represent a complex clinical syndrome with significant sexual dimorphism. Traditional “one‐size‐fits‐all” management often overlooks intra‐sex phenotypic heterogeneity. This study utilized unsupervised machine le...

Interfacially Assembled Hollow AuAg Nanostars on Flexible PDMS for Sensitive SERS Detection
