Two-Luminescent-Site Synergistic Responses in a Lanthanide-Functionalized Covalent Organic Framework for Ratiometric Fluorescence and Visual Detection of Cinoxacin Antibiotics

Abstract There is an urgent need to design a sensitive and rapid sensor for visual sensing of cinoxacin (CIN) antibiotics. Herein, a two-luminescent-site synergistic responsive ratiometric fluorescent sensing platform was rationally constructed by postsynthetically anchoring lant...

Generalization of Defense Effects Learned from a Single Adversarial Attack

Adversarial attacks misled deep neural networks by injecting perturbations into input images. Training networks with adversarial examples defended against adversarial attacks. However, training with specific adversarial examples only defended against the corresponding attacks. To...

Unraveling the Importance of Carboxyl Groups in Photochemically Excited Triplet Formation of Chromophoric Dissolved Organic Matter

Abstract Carboxylation and decarboxylation are among the most ubiquitous processes in chromophoric dissolved organic matter (CDOM) transformation, occurring during humification, photooxidation, and microbial activity. However, their impacts on the formation of excited triplet-sta...

Salt Stress Accelerates Tyrosine Depletion by Enterococcus lactis KUST2812: Multi-Omics Insights into Metabolic Remodeling

Enterococcus lactis KUST2812 is a halotolerant strain isolated from broad bean paste (BBP). It shows strong potential as a safe fermentation starter due to its high survival rate (98.32% in 18% NaCl), absence of hemolytic activity, and susceptibility to clinically relevant antibi...

TC-GAFnet: A Time-Aware Contrastive Grouped Attention Fusion Network with Empirical Priors for Adolescent Vision Prediction

Accurate prediction of spherical equivalent (SE) values is essential for early intervention in adolescent myopia management. Large-scale vision screening data provide valuable opportunities for longitudinal prediction; however, their utilization is challenged by sparse observatio...

Controlled Synthesis of Spherical Silver Powder via Bromide-Ion Capping of Silver Facets in Molten-Salt Electrodeposition for Photovoltaic Silver Paste

Abstract Spherical micro-nano silver powder plays a key role in heterojunction solar cells because it strongly affects electrode contact quality and ultimately device efficiency. However, conventional liquid-phase reduction usually relies on strong acids and organic reducing agen...

Stabilizing Grain Boundaries by Flexible Bidirectional Multisite Hydrazide Cations toward High-Performance Inverted Perovskite Solar Cells

Abstract The grain boundary instability induced by defects and tensible strain impedes the realization of high-performance inverted perovskite solar cells (PSCs). Here, we propose a flexible bidirectional multisite additive strategy to stabilize perovskite. (6-(2,5-Dioxo-2,5-dihy...

Towards Efficient and Explainable Road Crack Detection: A Transfer Learning-Driven SqueezeNet-based Approach

Abstract Under long-term exposure to complex environmental conditions and variable traffic loads, road pavements are generally prone to typical early damages such as cracking. Such defects can lead to severe structural deterioration and pavement service life reduction if not dete...

Investigation on energy collection characteristics of novel non-imaging cusp concentrator

In solar energy utilization, the concentrating performance of the conventional non–imaging cusp concentrator (NICC) is degraded due to the gap design. To address this, this paper conducts structural optimization design on NICC, thereby forming a novel non-imaging cusp concentrato...

Coherence‐Preserving Fluctuation Diagnostics for an Engineered Population‐Inverted Qubit Otto Engine

ABSTRACT Finite‐time quantum thermal machines require diagnostics beyond average work and efficiency because microscopic engines operate where fluctuations, incomplete thermalization, and coherence strongly affect performance. A coherence‐preserving fluctuation diagnostic is deve...

Thioredoxin-1 induces immune tolerance against α-syn presented by MHC-II in microglia via promoting Tregs differentiation in MPTP-induced Parkinson’s disease mice

Parkinson's disease (PD) is a common neurodegenerative disease characterized by the loss of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNpc) and the formation of Lewy bodies composed of misfolded alpha-synuclein (α-syn). A growing number of studies indi...

The Therapeutic Potential of Phages in Multi-Drug Resistance Infections and Future Directions

Phage therapy has been revisited as a biologically based strategy to tackle the escalating global crisis of multidrug-resistant (MDR) bacterial infections. Distinct from conventional antibiotics, bacteriophages target specific bacterial strains precisely, replicate locally at inf...

Transcription factor CCA1 interacts with RGL1 to regulate flowering in Arabidopsis

Flowering time is regulated by both external environmental cues and internal factors. CCA1(CIRCADIAN CLOCK ASSOCIATED 1) is a core component of the plant circadian clock. While previous studies have implicated CCA1 in flowering regulation, its underlying mechanism has remained in...

Hotspot to Homogeneous: Amorphous Interfacial Current Redistribution Enables Stable Solid-State Lithium-Metal Batteries

Abstract Interfacial instability in oxide ceramic electrolyte (OCE)-based solid-state lithium metal batteries (SSLMBs) is conventionally attributed to chemical incompatibility or mechanical failure, yet the underlying atomic-scale mechanisms remain elusive. Here, we reveal that g...
