Leaf–Litter–Soil C:N:P Stoichiometry Varies with Stand Age in Three Subtropical Plantation Types

Stoichiometry provides an integrative framework for evaluating nutrient dynamics in plantation ecosystems. However, whether stand-age-related changes in leaf–litter–soil carbon (C), nitrogen (N), and phosphorus (P) stoichiometry are consistent among plantation types remains uncle...

Characteristics, treatment patterns, and outcomes of patients with transthyretin amyloidosis: a large-scale, observational, retrospective study in China (OverTTuRe China)

Abstract Background Evidence remains limited on disease journey for transthyretin (ATTR) amyloidosis in China. This study aims to analyse China data from OverTTuRe, an observational, retrospective, multi-country cohort study. Methods Data were extracted from medical records (2013...

Corporate disclosures of carbon-reduction actions and firm value: the moderating role of digital transformation

Purpose This study examines whether corporate disclosures of carbon-reduction actions are associated with firm value under China's “dual-carbon” strategy. It further compares the valuation relevance of internally oriented operational disclosures and value-chain-oriented disclosur...

Development and exploratory external assessment of a machine learning model for early delirium prediction in non–mechanically ventilated patients with sepsis

Delirium is a common and severe complication of sepsis in critically ill patients and is associated with increased mortality and prolonged hospitalization. Early identification of high-risk individuals remains challenging, particularly among non–mechanically ventilated patients w...

Flash Laser Heating of Sn Single-Atom Reconstructed Graphene toward Multifunctional Thermal Management

Abstract Battery power loss, sluggish sensor response, and surface icing in low-temperature environments demand flexible and efficient thermal management materials. Here, we propose a flash-laser heating strategy to fabricate Sn single-atom anchored laser-induced graphene (Sn-SA@...

Femtosecond laser-patterned microfluidic surfaces with spreading carbon QDs toward dynamic information encryption

Traditional static optical anti-counterfeiting relies on fixed luminescent patterns or a single optical response, making it susceptible to copying and counterfeiting; moreover, its mode of information presentation is singular, making it difficult to meet the demands of informatio...

Polymorphic crystallites model for monolayer amorphous materials

Establishing atomistic models of amorphous materials remains a central challenge in materials science. Here, we examine three representative multicomponent monolayer systems using first-principles-trained machine-learning potentials and an energy-guided Monte Carlo structural-sea...

Network analysis of non-suicidal self-injury risk: school bullying, depressive symptoms, and psychotic-like experiences in 15,968 Chinese students

Abstract Background Non-suicidal self-injury (NSSI) is a major public health concern. While several factors have been associated with NSSI, their complex interactions and joint effects on NSSI remain unclear. This study examined the factors associated with NSSI using network anal...

Bisphenol A and Its Substitutes Bisphenol S/Bisphenol F in Combined Exposure Collectively Exacerbate Hepatotoxicity by Triggering Oxidative Stress and Inflammatory Responses via the PI3K-Akt/NF-κB Axis

Abstract Bisphenol A (BPA) and its substitutes bisphenol S (BPS) and bisphenol F (BPF) are environmental endocrine-disrupting chemicals that frequently co-occur. However, the hepatotoxic effects and underlying mechanisms of their combined exposure remain unclear. This study integ...

Exogenous pillaring engineering toward stable layered potassium manganese oxide cathodes

Layered potassium manganese oxides (KMO) offer a theoretically high energy density but intrinsically suffer from insufficient structural stability driven by Jahn–Teller lattice distortion. Herein, we report a spatially distributed pillaring structure that enables synergistic bulk...

Cellular and In Vivo Fate of DNA Nanostructures.

DNA nanotechnology is a cutting-edge discipline that exploits the principle of complementary base pairing to direct the self-assembly of precisely defined nanostructures. This review systematically surveys the fundamental concepts, assembly strategies, and biomedical applications...

Outward Charge-Enriched Boundaries Stabilize Halide–Sulfide Solid–Electrolyte Interfaces

Abstract Halide–sulfide bilayer electrolytes offer a practical route toward all-solid-state lithium batteries by combining the high-voltage compatibility of halide electrolytes with the favorable interfacial contact and Li+-transport characteristics of sulfide interlayers. Howeve...

Polyhydroxy Molecular Regulator Enabled Interfacial Microenvironment Programming for Alkaline Zinc–Iron Flow Batteries

Abstract Alkaline zinc–iron flow batteries (ZIFBs) are attractive for large-scale energy storage because of their low cost, intrinsic safety, and scalable architecture, yet their practical deployment remains hindered by hydrogen evolution and uncontrolled Zn deposition in three-d...

HyperLayout: A decoupled and planning-oriented framework for parcel-level building layout generation

Urban development is increasingly shifting from outward expansion toward the renewal and optimization of existing urban areas. This transition has created a growing demand for building layout generation methods that can satisfy complex planning requirements while maintaining soun...

Periostin attenuates senescence of human placental mesenchymal stem cells and enhances diabetic wound healing in rats

Refractory diabetic wounds are still big trouble for patients with diabetes, causing great mental and economic burdens. The application of mesenchymal stem cells (MSCs) represents a promising therapeutic strategy, but replicative senescence during ex vivo expansion limits MSC sel...

Use of a single CO₂ coolant in a Cascade manner for thermal protection of hypersonic vehicles

To address the thermal protection of hot-end components in hypersonic vehicles under extreme high-enthalpy aerodynamic heating, this study proposes and experimentally validates a channel–film combined cooling scheme based on the cascaded use of a single CO₂ coolant. Tests were co...

Synaptotagmin family proteins in neurological disorders: from synaptic vesicle fusion to neuronal vulnerability

The maintenance of neuronal and glial homeostasis depends on precise membrane fusion, vesicular trafficking, receptor turnover and stress-response signaling, processes regulated in part by synaptotagmin (SYT) family proteins. SYTs comprise a family of 17 mammalian membrane-associ...

Autologous Iliac Crest Bone Graft After Anterior Cruciate Ligament Reconstruction Failure in Patients With Both Femoral and Tibial Tunnel Enlargement
