Fe 3 d Electron Delocalization in Asymmetric Fe Single Atoms Enables Nonradical Peroxymonosulfate Activation for Micropollutant Degradation

Abstract Nonradical peroxymonosulfate (PMS) activation provides a selective route for micropollutant degradation, yet the orbital-level origin of oxidant speciation at single-atom sites remains unclear. Herein, an asymmetric Fe single-atom catalyst (Fe–N3–VN–C) is synthesized via...

Astronomical spectra as language: Order-agnostic foundation model for low-SNR reconstruction and stellar parameter prediction

Large-scale spectroscopic surveys contain numerous low-SNR stellar spectra that are difficult to analyze with traditional pipelines but remain valuable for Galactic archaeology, chemical-evolution studies, and population-level stellar characterization. We propose an order-agnosti...

Effects of human mobility on tuberculosis incidence in mainland China, 2010–2023: an ecological analysis and metapopulation modeling study

Human mobility plays an important role in the transmission of infectious diseases, yet its contribution to tuberculosis (TB) dynamics in China remains insufficiently quantified. We compiled a province-year panel for mainland China (2010–2023) to describe spatiotemporal trends usi...

A Generalization of Marstrand’s Theorem and Some Geometric Applications

Abstract In this paper we prove using quite elementary methods, with a combinatorial nature, two general results related to Marstrand’s projection theorem in a quite general formulation over metric spaces under a suitable transversality condition (the “projections" are in princip...

Equatorial Indian Ocean productivity over the last 200,000 years and links to deep circulation variations

Ocean circulation plays a key role in regulating atmospheric carbon dioxide levels during Pleistocene glacial-interglacial cycles. However, spatial responses of the oceans remain poorly constrained because reliable records from important carbon exchange regions, such as the equat...

Designof Chiral Antimony Catalyst for Ring-OpeningReaction of Epoxides with Anilines

Abstract Pnictogen-bonding catalysis has emerged as a promising tool for noncovalent transformations; however, its application in asymmetric catalysis remains in its infancy, largely due to the scarcity of efficient chiral catalysts and activating modes. Herein, we report a new c...

Fructose directly remodels the translocase of the outer membrane to impair oxidative phosphorylation in podocytes

Excessive dietary fructose consumption contributes to the rapidly increasing prevalence of obesity, metabolic syndrome, and chronic kidney disease worldwide, and accumulating preclinical evidence has confirmed that excess fructose exposure provokes severe mitochondrial dysfunctio...

Analyzing functional data with a mixture of covariance structures using a curve-based sampling scheme

Abstract Motivated by distinct walking patterns in real-world free-living gait data, this paper proposes an innovative curve-based sampling scheme for the analysis of functional data characterized by a mixture of covariance structures. Traditional approaches often fail to adequat...

Enzymatic degradation of conjugated polymer thin films for electrochemical transistors

Degradable imine linkers within the polymer backbone enabled acid-triggered organic mixed ionic–electronic conductors (OMIECs). Yet, for many bioelectronic applications, OMIECs must work in direct contact with physiological fluids, making it challenging to achieve both excellent...

“Trojan”Methionine Probe Reveals PKM2as a Methionine-Sensing Protein in the mTORC1 Pathway

Abstract Methionine (Met) plays a pivotal role in numerous cellular functions. Methionine restriction has been demonstrated to provide metabolic benefits in aging, obesity, diabetes and as an adjunct to cancer therapy. However, the methionine-sensing proteins and how cells direct...

Hydrogel-EmpoweredInterfacial Reactive Hydrogen onCopper Enables Selective Nitrate-To-Ammonia Electrocatalysis

Abstract Precise control of interfacial reactive hydrogen is crucial for improving the selectivity of proton-coupled electron transfer reactions in electrocatalysis. In the nitrate electroreduction to ammonia reaction, a fundamental trade-off is identified for copper (Cu)-based c...

Structure-BasedDesign and Optimization of Onradivir-DerivedPB2 Inhibitors for the Treatment of Influenza A

Abstract Influenza A remains a major seasonal public health burden. With the approval of onradivir, PB2 has emerged as an attractive antiviral target due to its unique and conserved structural features. Herein, using onradivir as the lead, we employed bioisosteric replacement str...

Steering Isotropic Li 2 S Growth via Bi‐Metallic Coupling: d ‐State Reengineering for Durable Li‐S Batteries

ABSTRACT Uncontrolled Li 2 S accumulation and high nucleation barriers severely hinder the sulfur utilization and cycle lifespan of lithium‐sulfur batteries (LSBs). Herein, we report an advanced bimetallic Mo 2 V 2 C 3 T x MXene as a functional separator modifier designed to acce...

Experimental causal inference from measurements alone in the presence of spatial and temporal quantum correlations

The causal structure of a set of events specifies which events influence which others. Determining this structure, known as causal inference, is a fundamental task in science. Reset-style intervention is commonly used to determine causal structure in classical scenarios. However,...

Falling dynamics of flexible plates with concentrated weight

We investigate the free fall of a flexible plate with a concentrated central weight using numerical simulations to explore the coupling effects of structural flexibility and concentrated loading. Two-dimensional and three-dimensional (3-D) simulations, combining lattice Boltzmann...

Self‐Growing Conductive Hydrogels Establish Volumetric Biointerfaces for Cardiac Conduction Restoration

ABSTRACT Restoring three‐dimensional electrical conduction in infarcted myocardium remains a critical challenge, as conventional conductive hydrogel patches largely remain surface‐confined and prevent electrical coupling of residual cardiomyocytes within fibrotic scars. Here, we...
