Genome-Wide Identification and Expression Analysis of Aquaporin Gene Family in 84K Poplar

Aquaporins (AQPs) mediate the transmembrane transport of water and diverse small molecules, playing essential roles in plant growth and development and stress responses. However, their genome-wide organization and evolution at the subgenome level in hybrid 84K poplar (Populus alb...

Collaborative governance for household livelihood resilience under climate change: evidence from China and a government–community–household framework

Enhancing household livelihood resilience under climate change requires attention not only to household assets and coping strategies, but also to the governance arrangements through which support, coordination, and feedback are organized. However, the mechanisms through which gov...

Network pharmacology and metabolomics analysis of ginsenosides in fibrinolysis balance after hip arthroplasty

Abstract Total hip arthroplasty (THA) is an effective treatment for end‑stage hip disease. However, postoperative fibrinolytic imbalance is common and increases the risks of bleeding and thrombosis. Ginsenosides, the main active constituents of Panax ginseng , exhibit multiple ph...

SUGP1 Deficiency Leads to Splicing Dysregulation and Reduced piRNA Abundance in Insects

SUGP1 (SURP and G-patch domain containing 1) participates in splice-site recognition through its interaction with SF3B1, and loss of this factor leads to aberrant splicing. While its role in pre-mRNA splicing is well-documented, its impact on small RNA pathways remains poorly und...

Plant DICER-LIKE, dual measurement RNA rulers

Small RNA (sRNA)-mediated gene silencing plays critical roles in eukaryotic gene regulation. The biogenesis of the two major types of sRNA, microRNA (miRNA) and small interfering RNA (siRNA), relies on the type III endoribonuclease Dicer. Unlike animals, which typically harbor fe...

Stability of nonlinear systems with delayed saturated impulsive control and its application to synchronization of coupled neural networks with switching topology

This study is presented on the local exponential stability (LES) of a class of nonlinear systems with discrete and distributed delays, using an impulsive control strategy that incorporates both input delays and actuator saturation. By integrating Lyapunov function theory, the Raz...

Dual-Responsive Dextran-Based Nanosystem for NIR Dual-Modal Imaging-Guided Photothermal-Chemotherapy of Breast Cancer

Abstract Breast cancer is a highly prevalent malignancy, but the conventional single chemotherapy suffers from insufficient therapeutic outcomes. To overcome this challenge, this study developed a dextran-based prodrug nanogel (DDIR) with dual pH/GSH responsiveness to the tumor m...

Federated Distillation: A Survey

Federated learning (FL) enables collaborative model training without centralizing clients’ raw data, but parameter exchange can impose substantial communication costs and usually requires compatible model architectures. Federated distillation (FD) instead transfers predictive or...

Sliding Ferroelectric Metals: An Emerging Frontier

ABSTRACT Sliding ferroelectric (FE) metals have emerged as a distinct paradigm in which interlayer sliding enables switchable out‐of‐plane polarization in a metallic state, overcoming the conventional incompatibility between FE switching and metallicity. This Perspective traces t...

Differential associations of aging attitude risk with depression, anxiety, and suicide-related risk among older Chinese adults: a network analysis and GGMNIRA-based simulated intervention study

Attitudes toward aging reflect how individuals understand and appraise their own aging process and may be closely associated with mental health in later life. Previous studies have primarily examined associations of attitudes toward aging with depression, anxiety, and suicide-rel...

Metabolic Analysis Reveals Alkaloid-Mediated Resistance of Tobacco against Ralstonia solanacearum

Abstract Tobacco (Nicotiana tabacum L.) is a globally important industrial crop, yet its productivity is severely threatened by bacterial wilt caused by R. solanacearum. In this study, integrative metabolomics and transcriptomics profiling of tobacco plants infected with R. solan...

Sparse Electromagnetic-Compatibility Flexible Electrodes for High-Accuracy, Fast-Recognition Human–Computer Interfaces

Surface electromyography (sEMG) gesture recognition technology offers significant potential for enhancing human-computer interaction and rehabilitation engineering by providing an intuitive and noninvasive method of engagement. However, challenges such as electromagnetic interfer...

Finite‐Time Synchronization of Delayed Coupled Memristive Neural Networks via Intermittent Pinning Control

ABSTRACT This work investigates finite‐time synchronization (FTS) of coupled memristive neural networks (CMNNs) with time delays by intermittent pinning control (IPC). It resolves the problem that delayed memristive neural networks (MNNs) cannot achieve FTS via intermittent contr...

Exceptionally Water‐Stable Hybrid Metal Halides via Divide‐and‐Conquer Strategy for Anti‐Counterfeiting and X‐Ray Imaging

ABSTRACT The lattice of organic–inorganic hybrid metal halides (OIMHs) is predominated by ionic interactions, which leads to spontaneous hydrolysis and structural collapse in water. Most prevailing stabilization approaches tend to either compromise photophysical performance to so...

Continuously Tunable Localized Surface Plasmon Resonance of Anisotropic Gold Nanopolyhedrons for Multiplexed Surface-Enhanced Raman Scattering Imaging

Abstract Surface-enhanced Raman scattering (SERS) is attractive for multiplex bioimaging owing to its excellent photostability and ultranarrow spectral bandwidth. However, achieving synergistic enhancement of excitation and Raman scattering fields remains challenging. Herein, the...

Comparative Hydrochemistry of Brines in Cambrian-Hosted Aquifer Systems: Evidence from Six Representative Regions

Comparisons of Cambrian-hosted brines across sedimentary basins are complicated by differences in initial salinity, host lithology, hydrogeological setting, and later fluid circulation. We compiled TDS, major-ion concentrations, stable water isotope values (δ18O and δD), and avai...

Genesis of Geothermal Water in Southwestern China: Insights from Hydrochemistry and Stable Isotopes

The research objective is to constrain the genesis and evolution of medium–low temperature geothermal waters hosted in carbonate rocks within complex fault-controlled settings, which represent cost-effective geothermal resources yet remain poorly understood in terms of their hydr...
