Ultrafast In-Plane Photo-Dember Ring at Buried Semiconductor Heterointerfaces Visualized by Scanning Ultrafast Electron Microscopy

Abstract The ultrafast transport dynamics of photogenerated carriers at buried semiconductor heterointerfaces govern the operation of modern optoelectronic devices, yet direct real-space visualization of in-plane carrier motion at such interfaces has remained an outstanding exper...

Functional Inequalities and Random Walks on Increasing Subsets of the Hypercube

Abstract. Motivated by random walks on subsets of the hypercube, we prove two discrete functional inequalities on the hypercube by the technique of induction-by-restrictions. First, we give a short, elementary proof of the Poincaré inequality on increasing subsets of the cube rec...

Designing the waiting experience: How order tracking shapes consumer engagement and loyalty

The post-purchase waiting period is an important yet underexamined stage of the digital customer journey. Consumers increasingly interact with order tracking systems during this phase, yet research has treated tracking primarily as a logistics tool rather than an experiential tou...

Recent Advances in Nanotechnology for Targeted Protein Degradation

Mutations or overexpression of proteins contribute to the pathogenesis and progression of numerous diseases, including cancers and neurodegenerative disorders. Traditional small-molecule inhibitors have played a crucial role in treating these diseases; however, they still face se...

Elastically bendable chiral metal halide crystals

Metal halide single crystals exhibit superior optoelectronic properties, promising for applications in optics and energy. However, they are inherently brittle, which has posed a major challenge for use in flexible electronics. Here, we report the elastic bending in a family of ch...

Activatable Nanovesicle Rewires Immunometabolic Barriers for NIR-II Photoacoustic-Guided Sono-immunotherapy of Glioblastoma

Abstract Glioblastoma (GBM) remains largely refractory to immunotherapy owing to a restrictive brain tumor niche that limits therapeutic access and fosters persistent immune evasion. Here, we present a programmed nanovesicle to sequentially overcome biological barriers and rewire...

Unveiling the Effect of π-Chain on Competitive Radiative and Non-Radiative Decay in Pyrene-Based Schiff Bases: ESIPT-AIE Fluorophores

Abstract Organic fluorophores combining excited-state intramolecular proton transfer (ESIPT) and aggregation-induced emission (AIE) offer enhanced photoluminescence properties. Herein, we have adopted a significant distance strategy for asymmetric pyrene Schiff bases (HPBC and 1H...

A Parameterized Algorithm for \({K_r}\)-Factors in Graphs of High Minimum Degree

Abstract. A [Formula: see text]-factor of a graph [Formula: see text] is a collection of vertex-disjoint [Formula: see text]-cliques covering [Formula: see text]. We prove the following algorithmic version of the classical Hajnal–Szemerédi theorem in graph theory, when [Formula:...

Donor‐Selective NiCo‐LDH Templating Directs Polymer Assembly for Enhanced Exciton Transport in Efficient Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) have achieved remarkable progress, yet improving exciton utilization in polymer donors remains challenging due to their intrinsically limited exciton diffusion length ( L D ). Here, we report a donor‐selective templating strategy based on few‐l...

Power outages, multi-product firms, and firm productivity: Theory and evidence from China

This study develops a model of multi-product firms (MPFs) to examine their responses to power outages and the consequent effects on firm productivity. In the model, MPFs mitigate the adverse effects of power outages by discontinuing their less-productive products and focusing mor...

Stabilizing Water Molecules in Hydrogel Electrolytes Enables 2.8 V‐Class Purely Aqueous Zn–Li Hybrid Batteries

ABSTRACT Currently, reported high‐voltage aqueous zinc batteries generally operate below 2.0 V. Achieving a discharge plateau/average operating voltage exceeding 2.0 V typically requires charging voltages above 2.5 V; however, the limited electrochemical stability of water molecu...

Timing of transurethral laser enucleation of the prostate after transperineal prostate biopsy: a multicenter cohort study

The optimal timing of transurethral laser enucleation of the prostate after transperineal prostate biopsy (TPB) remains uncertain. This study evaluated whether the interval between TPB and subsequent transurethral laser enucleation influences perioperative outcomes and postoperat...

Why does collective labor re-emerge in a marketized rural society? Evidence from rural China

As global market transformation and neoliberal restructuring deepen, labor relations have become increasingly individualized and commodified. Labor relations traditionally rooted in locality, kinship, and collective organization have gradually weakened in rural societies. Evidenc...

Why Peri‐Implant Tissues Are Susceptible to Inflammatory Breakdown—Single‐Cell Transcriptomics Reveals Immune Priming in Clinically Healthy Peri‐Implant Mucosa and CXCR2 + Neutrophil Activation in Peri‐Implantitis

ABSTRACT Aim Peri‐implant tissues are more susceptible than gingiva to rapid inflammatory breakdown, but the cellular basis of this vulnerability remains unclear. This study investigated (1) whether clinically healthy peri‐implant mucosa already displays an immune landscape disti...

EvidenT: An Evidence-Preserving Framework for Iterative System-Level Package Repair

Frequent toolchain updates and the expanding diversity of instruction set architectures (ISAs) have made large-scale system-level software package repair a critical task. Diagnosing and repairing build failures remains challenging due to heterogeneous failure evidence, complex de...

Mind the Gap: An Empirical Study of Synchronization Gaps, Delays, and Missed Opportunities in Software Forks

Fork-based development enables parallel evolution of software, but unsynchronized contributions create persistent divergence: security patches, bug fixes, and quality improvements often fail to propagate across fork families, leaving downstream users exposed to known vulnerabilit...

Quantitative Carleman‐type estimates for holomorphic sections over bounded domains

Abstract This paper establishes quantitative Carleman‐type inequalities for holomorphic sections of Hermitian vector bundles over bounded domains in with . We first prove a Sobolev‐type inequality with explicit constants for the Laplace operator, which leads to quantitative Carle...

Topological magnon noises

Abstract We develop a comprehensive formalism for magnon transport in ferromagnetic insulators driven by a temperature gradient. The formulas for magnon current and corresponding magnon noise are derived herein based on the spin Hamiltonian of a topological magnon insulator, whic...

Prevalence and geographic variation of enteric pathogens among asymptomatic individuals in China: a nationwide, cross-sectional, multiplex molecular survey

The increasing use of multiplex molecular assays has improved the detection of enteric pathogens, but baseline carriage in asymptomatic populations remains poorly characterized, complicating the interpretation of positive test results. We aimed to investigate the prevalence and g...

Sustained Fe3+/Fe2+ Cycling Enables Photochemical Defluorination of Perfluoroalkyl Carboxylic Acids via Ligand-to-Metal Charge Transfer

Abstract Per- and polyfluoroalkyl substances (PFASs) are widespread persistent pollutants that threaten environmental and human health. Although Fe3+-mediated ligand-to-metal charge transfer (LMCT) has been shown to promote PFAS photochemical defluorination, existing systems rely...
