SQQ: Python Joint Toolkit for Water-Shell Topology Analysis

Abstract Order parameters are essential for molecular dynamics structures of crystalline water, as they provide quantitative measures of phase change. Yet conventional descriptors cannot directly resolve water-ring connectivity, face adjacency, or cage closure. Here, we develop t...

To Run or Not to Run: Analyzing the Cost-Effectiveness of Code Execution in LLM-Based Program Repair

LLM-based agents for program repair are increasingly built on a “generate-run-revise” paradigm, iteratively executing tests to evaluate and refine patches. This execution-based approach has become standard practice in state-of-the-art systems. However, executions can be time-cons...

From citation intent to knowledge contribution: Classifying what cited papers actually contribute

Abstract Understanding the flow and evolution of scientific knowledge is essential for assessing research impact. Existing citation analysis methods mainly focus on citing authors' subjective intents, failing to consistently characterize cited papers' knowledge contributions. Thi...

DentalGEN: a large-scale controllable generative AI framework for automated dental crown restoration

Dental crown restoration addresses a global public health burden, yet is constrained by a slow, variable, and labor-intensive manual design process that limits access to high-quality treatment. Here we introduce DentalGEN, a large-scale controllable generative artificial intellig...

From Direct to Alternating Current Electrosynthesis: Transition-Metal-Catalyzed Oxidative Cross-Coupling with Hydrogen Evolution

Conspectus Electrochemical transition-metal catalysis is an effective yet underexplored platform for molecular construction. Combining the advantages of electrochemically driven oxidation processes with the selectivity control afforded by transition-metal catalysis, this field is...

AMET-YOLO: A Pear Leaf Disease and Pest Detection Model Integrating Multi-Strategy Feature Enhancement and Task Alignment

Accurate and robust detection of pear leaf diseases and pests is important for early warning in orchards, precision control, and intelligent disease and pest management. In natural environments, this detection task is still difficult because target scales vary greatly, lesion bou...

A novel transient zero-dimensional physics-based model of vanadium redox flow batteries with electrolyte crossover-induced capacity fade

Conventional lumped models of vanadium redox flow batteries (VRBs) typically neglect bulk electrolyte transfer because its effects are often insignificant over short time scales. This simplification, however, prevents accurate representation of electrolyte crossover-induced volum...

Nanopore-Induced Thickness Independence of In-Plane Thermal Transport in Few-Layer Graphitic Carbon Nitride

Abstract Although in-plane thermal transport in many two-dimensional (2D) materials exhibits pronounced thickness dependence, it remains unclear whether this behavior persists in intrinsically porous 2D systems. In this work, we employ a scalable, high-accuracy atomistic simulati...

Fracture characteristics of layered rock during supercritical carbon dioxide fracturing: an experimental and thermal–hydraulic–mechanical–damage numerical study

Rock heterogeneity and structural anisotropy exert significant influences on fracture propagation during reservoir stimulation. Focusing on layered sandstone, this study conducted supercritical carbon dioxide (SC-CO₂) fracturing experiments under different stress ratios and beddi...

Hierarchical operation optimization of reserve storage capacity in pumped-storage power stations for enhanced high-penetration renewable energy accommodation

Pumped-storage power (PSP) stations play a vital role in promoting renewable energy accommodation, yet the operational potential of their reserve storage capacity (RSC) remains insufficiently exploited. This study proposes a hierarchical control framework for RSC in PSP peak-shav...

Hierarchical microbial distribution organized by ordered river structure explains why GHG emission favors small streams

In river networks, small streams usually emit the largest proportion of greenhouse-gases (GHGs). However, the associated microbial mechanisms affected by the hierarchy of river systems are unclear. To address this, we measured N 2 O, CH 4 and CO 2 fluxes at 22 sites selected from...

C/EBPβ/AEP pathway mediates synaptic impairments and depression-like phenotypes induced by chronic stress

Depression is a common psychiatric disorder characterized by episodes of low mood. Disruptions in synaptic homeostasis contribute to the onset of depression. However, the molecular mechanisms underlying synaptic impairments in depression remain elusive. Here we show that chronic...

Multi-facility GNSS antenna calibration

Abstract Accurate antenna calibrations are a cornerstone of high-quality global navigation satellite systems (GNSS) positioning, time and frequency transfer, precise orbits, and troposphere estimates. The international GNSS service (IGS) antenna committee maintains antenna phase...

Some General Features of Curing Temperature Effects on Strength Behavior of Various Cement-Bound Materials

Abstract Curing temperature critically influences the strength behavior of cement-bound materials (CBMs), including concrete, mortar, and cement-stabilized soil (CSS). Existing reviews mostly address these systems separately, lacking a unified perspective essential for understand...

Safety and Efficacy of Left Atrial Ablation After Percutaneous Left Atrial Appendage Occlusion in High-Bleeding-Risk Patients with Atrial Fibrillation: A Multicenter Analysis from the PROCEED-AF Ablation Registry

BACKGROUND AND AIMS: Patients with left atrial appendage (LAAO) devices are increasingly referred for AF ablation, yet anticoagulation strategies remain uncertain. The goal of this study was to evaluate the safety and efficacy of catheter ablation for atrial fibrillation (AF) in...

Controlled Epoxide-Enabled Formal Oxygen Insertion of Indenones to Isocoumarins

Abstract Regioselective oxygen insertion into sp2-rich carbonyl scaffolds remains challenging because Baeyer–Villiger oxidation relies on migratory aptitude. Here, we translate an aziridine-based nitrogen-insertion platform to an epoxide-enabled oxygen-insertion manifold for inde...

Bulk 1T-NbSe2 Superconductor Stabilized by the Doped Ti-3d0 Electronic Configuration

Abstract Metastable 1T-phase transition-metal dichalcogenides host rich strongly correlated electronic phenomena, yet the synthesis of bulk 1T-NbSe2 remains a challenge. This difficulty stems from the energetic penalty associated with the octahedral coordination of Nb4+, whose 4d...
