Dual-Optimized Medium-Entropy Alloy Heterojunction: Synergistically Enhancing Surface Kinetics and Interfacial Mass Transfer for Hydrazine-Assisted Hydrogen Evolution

Abstract To address the prominent “bubble shielding” effect at high current densities during hydrazine oxidation reaction (HzOR) as a replacement for the traditional oxygen evolution reaction (OER), this study successfully designed a medium-entropy heterojunction electrocatalyst...

Closed-Form and Boundary Expressions for Task-Success Probability in Status-Driven Systems

Status-driven task offloading appears in many systems such as vehicular coordination, UAV control, and compute-first networking, where an user-side node (or access point, AP) forwards user tasks based on periodically received server status. Whether a task ultimately succeeds depe...

Data-driven modeling of Galactic diffuse emission with multi-wavelength observations

Abstract We present a data-driven investigation of Galactic diffuse emission. Using multi-frequency Planck maps (30–857 GHz), we construct a non-linear mapping between microwave-to-far-infrared and gamma-ray intensity through supervised machine learning. Our models achieve high p...

Reconfigurable Charge Transfer Between Type‐II and Z‐Scheme in WO 3 /Cu 2 O for All‐Day Photoreduction of CO 2

ABSTRACT Solar‐driven CO 2 conversion to high‐value chemicals provides a sustainable solution to energy and climate challenges, but its practical use is limited by sunlight intermittency. Since photocatalytic CO 2 reduction relies on photogenerated electrons, sustaining electron...

DDSF-UNet: dual-domain spatial–frequency learning for underwater image enhancement

Abstract Underwater image enhancement (UIE) is still difficult. This is mainly due to wavelength-dependent light absorption, scattering, and environmental noise, which lead to low visibility, color distortion, and loss of fine details. Most existing deep learning (DL) based model...

The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200...

Apiin from sugarcane leaves modulates postprandial hyperglycemia by targeting dipeptidyl peptidase IV, α ‐amylase, and α ‐glucosidase

Abstract BACKGROUND Postprandial hyperglycemia is a metabolic abnormality that can emerge early in the progression toward type 2 diabetes and is closely associated with insulin resistance. Sugarcane leaves, an underutilized by‐product of sugar production, are rich in flavonoids a...

Carbohydrate‐binding modules: powerful tools in the research and development of carbohydrates – a review

Abstract Carbohydrate‐binding modules (CBMs) are independent domains generally appended in carbohydrate‐active enzymes (CAZymes) with carbohydrate‐binding functions. The primary roles of CBMs in CAZymes include targeting, proximity, disruption, and adhesion effects. Due to their...

Single-Atom Ce Enables Interfacial Pathway Regulation of Fe2 Atomic Pairs in Alkaline Oxygen Reduction

Abstract Fe2 atomic pairs are among the most active motifs in Fe–N–C catalysts for the alkaline oxygen reduction reaction (ORR), but their performance is limited by an activity–stability trade-off. In alkaline media, slow interfacial water dissociation restricts proton-coupled el...

Valuing ecosystem services in marine ranching development: evidence from a choice experiment in Qingdao, China

Marine ranching is increasingly regarded as an important mode of coastal fisheries upgrading and ecosystem restoration. Robust valuation of its ecosystem services is therefore essential for informing public investment decisions and policy design for the sector's sustainable devel...

Cellular remodeling during reversible life-stage transition in sessile ciliates: Genomic and transcriptomic insights

Unraveling mechanisms driving dramatic life-stage transitions in response to environmental stress is central to understanding cellular adaptation. We studied a distinctive group of sessile ciliates that undergo profound morphological and organellar remodeling when transitioning f...

Tectono-magmatic–volatile coupling in postcollisional giant porphyry Cu formation: Evidence from slab tearing and mantle inputs at Qulong, Tibet

The origin of postcollisional porphyry copper deposits (PCDs) within thickened crust remains debated, particularly regarding the coupling between tectono-magmatic–volatile evolution and ore formation. At Qulong, Tibet, new geochemical and isotopic data across four Miocene intrusi...

Fluorescent Molecular Scaffold-Building Mononuclear Iron(II) Complexes Display Synergistic Spin Crossover and Fluorescence Behaviors

Abstract Magnetic fluorescent bifunctional spin crossover (SCO) materials show switchable magnetic and optical properties and have attracted continuous research interest due to their potential application in magneto-optical switches and multi-sensors. Herein, we report two octahe...
