Vectorized SVE2 Optimization of the Post-Quantum Signature ML-DSA on ARMv9-A Architecture

Post-quantum cryptography (PQC) is essential to securing data in the quantum computing era, and standardization efforts led by NIST have driven extensive research on practical and efficient implementations. With the emerging deployment of ARMv9-A processors in mobile and edge dev...

Reversible Oxygen Redoxin High Voltage for Lithium-RichLayered Oxides

Abstract Lithium-rich layered oxides, characterized by Li ions in the transition-metal layers, can significantly increase battery energy density through the introduction of oxygen redox. However, these cathodes often suffer from substantial voltage hysteresis, leading to a consid...

Artificial PhotosyntheticHydrogel Microspheres asa Versatile Platform for Programmable CO2 Valorization

Abstract Carbon-negative biomanufacturing is essential for global sustainability. Artificial photosynthesis based on material-microbe hybrid systems holds promise but suffers from inefficient energy supply, phototoxicity, abiotic–biotic incompatibility, and limited product spectr...

Cavity-Size-Dependent Recognition of Naphthalene Derivatives by 3,3′-Bipyridinium Tetracationic Cyclophanes

The recognition behavior of tetracationic cyclophanes is strongly influenced by the geometric match between the host cavity and aromatic guests. Herein, we compare two 3,3′-bipyridinium-based tetracationic cyclophanes, BPy-Box⁴⁺ and NBox⁴⁺, toward a series of naphthalene derivati...

Mechanisms and therapeutic strategies of asthma: from bench to bedside

Asthma is a heterogeneous chronic airway disease arising from a complex interplay of genetic susceptibility and environmental exposures. Key pathobiological features include dysregulated immune responses (particularly type 2 inflammation), structural airway remodeling, and mucus...

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,...

Precise Management of n‐Value Distribution at the 2D/3D Interface Enabling Efficient Wide‐Bandgap Perovskite Solar Cells

Introducing a 2D perovskite layer on the surface of 3D perovskite has been broadly recognized as an effective strategy to enhance the performance of perovskite solar cells (PSCs). However, the mechanism governing the 2D phase formation remains uncertain. In this work, the phase t...

Atomic High-Spin Cobalt Unlocks Reversible Multi-Electron Transfer Chemistry for Superb Aqueous Zn-Mn Batteries

Abstract To settle inherent irreversible phase transition and motivate re-dissolution of deposited “dead” MnO 2 without acid and redox mediator addition, we introduced atomic-dispersed Co atoms with high-spin state into layered MnO 2 , denoted as Co–MnO 2 , via an in situ topolog...

Chemistry‑Driven Engineering of PEDOT:PSS Hydrogels for Next‑Generation Bioelectronic Interfaces

ABSTRACT Poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) hydrogels have emerged as a versatile class of mixed ionic‐electronic conductors for next‐generation bioelectronic interfaces, owing to their unique combination of high conductivity, mechanical complianc...

Reconstructing Solvation Structure via Strongly Nucleophilic Anions for High‐Rate and Low‐Temperature Graphite||LFP Pouch Cells in PC‐Based Electrolyte

ABSTRACT Regulating Li + solvation structure in Propylene carbonate (PC)‐based electrolytes modulates solid‐electrolyte interphase (SEI) formation and desolvation, enabling compatibility with graphite anodes. However, existing high‐ and localized high‐concentration strategies rem...

Age-Associated Patterns of Cardiovascular Risk and Disease Phenotypes Across Diverse Care Settings: The GLOB-cAGE Consortium

Reported prevalence of cardiovascular disease (CVD) risk factors and phenotypes varies widely. In multi-cohort analyses, such variation reflects population risk, care setting, and data capture. We harmonized baseline data from four analytic cohorts (N=54,188, aged ≥50 years) in f...

Emerging Near‐Infrared Optical Materials Based on Supramolecular Charge Transfer Complexes

ABSTRACT Organic charge transfer complexes (CTCs), formed by donor–acceptor (D–A) coassembly, have emerged as a supramolecular platform for programmable near‐infrared (NIR) optics. In their D–A assemblies, packing‐dependent electronic coupling and delocalization generate tunable...

Fructose induces PERK-dependent ER stress and mitochondrial dysfunction via nucleotide depletion in clear cell renal cell carcinoma

Abstract Clear cell renal cell carcinoma (ccRCC) exhibits a paradoxical fructose metabolism signature characterized by upregulation of the fructose transporter GLUT5 alongside downregulation of the catabolic enzymes (ketohexokinase, aldolase B, and triokinase), a pattern associat...

Distinct Sex-Specific Characteristics of Apoe Deficient and Ldlr Deficient Mice in Atherosclerosis: Implications for Model Selection and Therapy Development

The progression of cardiovascular disease shows significant sexual dimorphism: although females generally develop the disease later in life, they exhibit a higher age-related incidence than males. While current studies have separately reported sex differences in atherosclerotic d...

Improved building performance prediction model based on the OODA-MDOB approach

Abstract The neglect of subjective factors such as cost consideration and accessibility in occupant behavior models leads to unrealistic device usage simulations, which ultimately undermines prediction accuracy. To address this gap, this paper proposes a Multi-Device Occupant Beh...

Cumulative non-high-density lipoprotein cholesterol exposure and residual cardiovascular mortality risk in patients with peripheral artery disease

Abstract Background Individuals with peripheral artery disease (PAD) face substantial residual cardiovascular risk despite lipid-lowering therapy. Non-high-density lipoprotein cholesterol (non-HDL-C) has been recognized as a more comprehensive marker of cardiovascular risk than l...

Mitigating Stress‐Induced Nonphotoactive Phase Transition Through Sodium Sulfonate Engineering for Stable and Efficient Perovskite Solar Cells

ABSTRACT Formamidinium lead triiodide (FAPbI 3 ) perovskite solar cells (PSCs) have attracted significant attention due to their outstanding optoelectronic properties. However, their long‐term stability remains limited by lattice strain‐induced transition from the photoactive α‐p...

Inter-DropletElectric Fields Drive Water Redox Chemistryin Microdroplets

Abstract The chemistry of water microdroplets is often interpreted from the perspective of isolated droplet interfaces, although practical microdroplet systems more commonly exist as dense ensembles of interacting droplets. Here, we show that a closed reactor based on ultrasonic...

A miniaturized synaptic quantum dot light-emitting diode integrating neuromorphic vision and display

Artificial vision systems conventionally segregate sensing, memory, processing, and display into discrete modules, incurring latency, energy penalties, and architectural complexity. Here, we report a miniaturized synaptic quantum-dot light-emitting diode that monolithically integ...
