Two Additional New Species of Feihyla Sensu Stricto (Anura, Rhacophoridae) from Yunnan Province, China

Two new species of Feihyla sensu stricto are described based on specimens from western and southwestern Yunnan Province, China. Morphologically, the first new species from western Yunnan can be distinguished from other known species of Feihyla sensu stricto by the body size, the...

Hexacatenar Columnar Liquid Crystals with a Perfluoronaphthalene-Core: Synthesis, Self-Organization, Charge Transport and Photoluminescence

Abstract Columnar liquid crystals featuring one-dimensional charge transport and self-assembly are of considerable interest for organic electronic applications such as organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Fluorination emerges as a po...

Extrapolating Molecular Correlation Energies to the Complete Basis Set Limit with Symbolic Regression

Abstract Basis set extrapolation is an important strategy for reducing basis set incompleteness error (BSIE) in correlation energy calculations. However, extrapolating correlation energies from double-ζ/triple-ζ (DZ/TZ) levels to the complete basis set (CBS) limit remains challen...

Neural dynamics of reconstructing knowledge structure from temporally disordered inputs

Humans possess a remarkable ability to integrate fragmented experiences into coherent internal models. However, the neural dynamics supporting structure reconstruction from temporally disordered inputs remain poorly understood. Here, we show that knowledge reconstruction follows...

Facilitating residents’ storytelling in tourism communities: Communication infrastructure and acculturation

Storytelling has become an important means of destination branding, with residents as key creators and disseminators of local narratives. However, the structural and cultural conditions that enable residents' storytelling behavior remain insufficiently understood. Drawing on Comm...

2D theoretically twistable material database

The study of twisted two-dimensional (2D) materials, in which twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly correlated physics. The broader potential of a seemingly infinite set of twistable 2D materials re...

Polarization-controlled ultrafast carrier dynamics in sliding ferroelectrics revealed by machine learning-accelerated nonadiabatic dynamics simulations

Sliding ferroelectrics offer a unique pathway to electrically reconfigurable polarization at the atomic scale, offering compelling opportunities for ultralow-power optoelectronic devices. Yet, despite rapid advances in materials discovery, the fundamental question of how polariza...

Myricitrin Delays Caenorhabditis elegans Aging: Association with DAF-16, SIR-2.1, and Potential Cholinergic Modulation

Background: Aging involves progressive functional decline driven by oxidative stress and mitochondrial dysfunction, and dietary flavonoids are promising aging interventions due to their multi-target regulatory pathways. Methods: This study systematically evaluated the anti-aging...

Removal Efficiency and Transformation Mechanism of Refractory Organic Matter in Food Industry Wastewater Treated by the UV/H2O2 System

Abstract To address the unclear removal efficiency and transformation mechanism of refractory organic matter in food industry wastewater (FIW), this study employed the UV / H 2 O 2 system to conduct deep treatment on the biological effluent from dairy, meat, edible oil, and hot p...

ABE-FL: Efficient and secure federated learning based on CP-ABE with high-security elliptic curves

Existing secure federated learning (FL) schemes suffer from three major limitations: (1) the initial global model is unprotected during distribution; (2) multi-party computation incurs high communication overhead; and (3) the use of homomorphic encryption (HE) for parameter prote...

A Deep Model Framework for Morphological Trait Imputation Across Taxonomic Groups

ABSTRACT Incomplete morphological trait data pose major hurdles for trait‐based analyses, particularly when missing values, multicollinearity, and sparse sampling constrain inference. These issues limit our ability to quantify trait variation and explore broad patterns of functio...

Oxytocin modulates white matter functional connectivity tensor dynamics and circuit-targeted reconfiguration in depressive symptoms

Major depressive disorder involves disrupted neural circuit dynamics. While oxytocin has demonstrated modulatory effects on functional connectivity, its therapeutic potential for depression, particularly through white matter circuit modulation, remains poorly understood. Here we...

Experimental and theoretical analysis of the smoldering-to-flaming transition in moist pine needle beds under unsteady wind flow

Background Smoldering in forest litters is prone to transition to flaming under dry and windy conditions. Most studies focus on smoldering-to-flaming (StF) transition under steady wind conditions, however, a knowledge gap persists regarding periodic wind oscillations in wildfires...

Laccase‐induced structural remodeling of cottonseed protein for improving its emulsion stability and curcumin bioaccessibility

BACKGROUND: Cottonseed is an important byproduct of cottonseed processing and is rich in proteins. A literature review indicated that cottonseed protein isolate (CPI) demonstrated a compact structure because of its limited exposure of hydrophobic groups, leading to poor emulsifyi...

Equivalence relations derived from $U$- and $V$-partial orders on bounded lattices: different neutral and zero elements perspective

This paper investigates the equivalence relations and algebraic structures induced by $U$-partial and $V$-partial orders on bounded lattices, respectively, with respect to the different neutral and zero elements. The study begins by presenting the equivalence classes associated w...

Weak Acceptors Abnormally Reinforce Urethane Networks while Enabling Glassy-State Healability

Abstract Hydrogen bonds are versatile motifs for designing repairable materials. The current preconception is that while weak hydrogen bonds lead to rapid exchanging dynamics beneficial for healing, they compromise mechanical properties by reducing the overall cohesion of the mat...
