Prospects and complexities in sustainability impacts of global residue-based bioenergy deployment

Amid rising global demand for sustainable energy, agricultural and forestry residues (AFRs) emerge as a key yet underutilized resource in energy transition. Mechanisms of how optimizing multipath AFR utilization advances sustainability contributions in varied socioeconomic contex...

Integrated BSEM-Raman reveals the spatial heterogeneity of mineralogical phases in KOH-GGBS pastes

The large volume utilisation of GGBS from locally available sources remains challenging in China because compositional variability influences the long-term degree of slag reaction, spatial heterogeneity, assemblage, and chemistry of the resulting reaction products. This study int...

Hydrophobic Microphase Separation‐Driven Polycondensation and Carbonization for the Formation of Carbonized Polymer Dots

ABSTRACT Hydrothermal synthesis has been widely used to prepare carbonized polymer dots (CPDs) in a one‐pot manner, yet how initial precursors evolve into nanoparticles in water‐rich environments remains poorly understood. Here, hydrophobic microphase separation is identified as...

Formation of LiFN2 with puckered LiF layers via nitrogen intercalation under high pressure

The incorporation of molecular guests into ionic frameworks under pressure can produce host–guest structures inaccessible under ambient conditions. Here, we report the synthesis of an intercalated compound, LiFN2, at 105 GPa and 2100 K using the laser-heated diamond anvil cell te...

Electrochemical Solubility Switching Enables Lateral Etching Toward Sub‐20 nm Nanopatterning

The miniaturization of patterns to sub-20 nm dimensions remains challenging, owing to the fundamental constraints of optical patterning and the increasing complexity and cost of advanced lithographic technologies such as extreme-ultraviolet lithography. Here, we introduce an elec...

Energy-Transfer Pathways in Nd-Sensitized Er-Rich Nanostructures: The Competition between Cross-Relaxation and Phonon-Assisted Sensitization

Abstract Rare earth-doped upconversion nanomaterials, which convert near-infrared light into visible or ultraviolet light, are widely recognized as having a huge potential application market, which unfortunately is restricted by their obstinate insufficient luminescence efficienc...

Frailty-Related Metabolic Signature in the Association Between Frailty and Coronary Artery Disease: Modification by Genetic Susceptibility

Background Frailty is associated with increased coronary artery disease (CAD) risk, but the circulating metabolic features underlying the frailty–CAD relationship and their interplay with genetic susceptibility remain unclear. This study aimed to identify a frailty-related metabo...

Dynamic Thermal Characteristics of the Liquid Hydrogen Tank Filling Process Under Different Gas Phase Space Configurations

The gas phase space influences liquid redistribution and pressure evolution during liquid hydrogen (LH2) filling, but the effects of its geometry remain insufficiently understood. A 34 L onboard LH2 tank was investigated using a two-dimensional volume-of-fluid (VOF) model incorpo...

Seismic Signal Denoising via RRTO-Optimized VMD Combined with Spectral Kurtosis and Enhanced Wavelet Packet Thresholding

Abstract Seismic signal denoising is a key link to improve the interpretation accuracy of seismic data, especially in the complex noise background, where random noise and coherent noise will seriously interfere with the identification and extraction of effective signals. To this...

A multicenter multistate modeling on the natural history of liver decompensation: Longitudinal analysis of 1777 patients.

BACKGROUND: Cirrhosis often remains silent until decompensation, after which survival deteriorates sharply. Contemporary, transition-aware estimates are limited, especially in Asian-predominant cohorts. We analyzed trajectories from compensated advanced chronic liver disease (cAC...

An imputation method for single‐cell RNA sequencing data based on a parallel gated recurrent unit neural network

Abstract Single‐cell RNA sequencing (scRNA‐seq) generates high‐dimensional transcriptomic data but is severely affected by dropout events, which obscure true gene–gene relationships. These missing values introduce bias into downstream analyses, complicate data processing, and red...

Domino effect enables dynamic electronic structure evolution for stable and efficient water purification

The purification of water contaminated by persistent organic pollutants remains a critical global challenge, largely due to the intrinsic trade-off between high catalytic activity and long-term stability in advanced oxidation processes. Despite the tremendous potential of single-...

Maximum Principle for Optimal Control of Infinite Horizon Stochastic Difference Equations Driven by Fractional Noises

Abstract. In this paper, infinite horizon stochastic difference equations and backward stochastic difference equations with fractional noise are studied. The main difficulty comes from the self-dependence of fractional noise on an infinite horizon. By introducing the infinite hor...

Piezoelectric-Actuated Flexible Undulating Fins for Biomimetic Surface Robot Propulsion: Design, Modeling, and Experimental Evaluation

Small unmanned surface vehicles operating in confined, vegetation-rich, or ecologically sensitive waters require compact propulsion systems that minimize entanglement and unintended contact. Here, we present a 178 mm biomimetic surface robot propelled by bilateral flexible fins a...

Protective effect of Lacticaseibacillus paracasei Jlus66 against Salmonella in a mouse model

Abstract Given the increasing prevalence of antibiotic-resistant strains and the presence of antibiotic residues in poultry products, the adoption of biocontrol strategies as alternatives to antibiotics has become increasingly crucial for ensuring food safety. This study aimed to...
