Catalyst-free Polyannulations of Potassium Sulfide and Unactivated Alkynes toward Multifunctional Thiophene-Containing Polymers

Abstract Facile and efficient transformation of inexpensive inorganic sulfides into high-value polymer materials is of great academic and industrial significance. Herein, we report a catalyst-free polyannulation strategy between potassium sulfide and internal diynes, which can ef...

Physically inspired geometry-to-photometry rendering and lightweight convolutional neural network for real-time weld defect detection

Welding quality inspection of battery top covers is critical to lithium-ion battery safety and reliability. The height deviation between weld defects and normal areas is extremely small; on specular, weakly textured surfaces it produces no stable brightness contrast, so two-dimen...

Vertex Hashing Assignment‐Based Distributed Sampling Algorithm for Large‐Scale Dynamic Graph Stream

ABSTRACT In recent years, research on triangle counting in large graphs has primarily focused on estimating the number of triangles in static graphs. Most streaming graph sampling algorithms are only capable of estimating triangle counts in static graphs and cannot handle dynamic...

Evaluating the efficacy of pressure microcatheters for fractional flow reserve measurement in chronic thromboembolic pulmonary hypertension: a comparative study

This study aimed to compare the efficacy and procedural performance of pressure microcatheters and pressure guidewires for fractional flow reserve (FFR) measurement in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BP...

Atomic Site-Specific Eigenstrain for Efficient Electrocatalysis

Abstract Strain engineering is a powerful approach to tailoring the performance of metal electrocatalysts. Despite substantial advancements in controlling the average surface strain and establishing its correlation with catalytic activity, the impact of strain at individual activ...

Temporal Faraday Effect Enabled by Floquet‐Induced Chirality

ABSTRACT The Faraday effect is a hallmark of nonreciprocal light–matter interactions and traditionally requires magnetic bias or intrinsically chiral media. Here we introduce a temporal chiral metamaterial in which an effective chiral response is generated entirely by Floquet mod...

Sensitivity of Satellite-Derived Gross Primary Productivity to Environmental and Canopy Inputs in a Subtropical Mangrove Forest

Accurate estimates of mangrove gross primary productivity (GPP) are needed to quantify coastal carbon dynamics, but the performance of satellite-based GPP models in mangrove forests remains uncertain. We compared eight models—four light-use-efficiency models (MOD17, EC-LUE, VPM,...

How Heat Stress Mediates the Impacts of Street-level Environmental Features on Housing Prices: A Comparative Study of Center City and Outside Areas in Philadelphia

Urban heat increasingly shapes housing markets, but existing studies often use coarse data and overlook spatial differences. This study develops an SEM-centered framework, with RF-SHAP as a non-parametric robustness check, to examine how 1-meter Universal Thermal Climate Index (U...

Safeguarding global terrestrial vertebrate species from future sea-level rise

Sea-level rise (SLR) threatens terrestrial biodiversity, yet its spatiotemporal and species-specific impacts remain unclear. Integrating relative SLR projections across five Shared Socioeconomic Pathways (SSPs) with Area of Habitat (AOH) maps for 34,120 terrestrial vertebrate spe...

Deep Learning-Enhanced Lateral-Flow Microarray Biosensor for Multiplexed Inflammatory Biomarker Analysis

Abstract Beyond simply functional integration, achieving synergistic enhancements in multiplex detection, quantitative robustness, and intelligent analysis remains a key challenge for next-generation biosensing platforms in precision diagnostics. Lateral flow biosensors are attra...

A novel unified loading path design method for rock dynamic and static triaxial loading: An analytical investigation

True triaxial testing technique is one of the research focuses in rock mechanics, where appropriate loading paths are critical for triaxial experiments. However, dynamic true triaxial testing remains at an early stage of development, and conventional loading procedures developed...

Abstract This work presents an engineered single-plasmid, dual-pigment whole-cell biosensor for simultaneous colorimetric detection of Pb(II) and Hg(II). To address the challenge of signal interference in cocontaminated environmental samples, a Pb(II)-responsive PbrR regulatory m...

UAV-based super-resolution instance segmentation enables ecological monitoring of sea cucumbers in shallow coral reef habitats

Accurate monitoring of sea cucumbers from UAV imagery remains challenging because submerged individuals often exhibit low contrast, camouflage against coral-rubble backgrounds, and weak boundary information under water-surface disturbance. In particular, key visual cues such as b...

Fenton-Mediated Surface Modulation of Microplastics: Effects and Mechanisms on the Fluorescence Response of Nile Red Staining

Abstract Nile Red (NR) fluorescence staining enables rapid microplastic (MP) screening, but weak dye affinity and matrix-derived false positives limit quantitative reliability. This study investigated whether controlled Fenton digestion can modulate microplastic surfaces to enhan...
