In situ evidence of tiered adaptations buffering a chemosynthetic clam holobiont against environmental sulfide fluctuations

Deep-sea holobionts adapt to extreme environmental fluctuations, but the molecular mechanisms underlying resilience remain poorly understood. We investigated the vesicomyid clam Archivesica marissinica and its sulfur-oxidizing symbionts during sulfide shortage via in situ transpl...

Multi-granularity spatiotemporal flow patterns

Abstract Analyzing flow of objects or data at different granularities of space and time can unveil interesting insights or trends. For example, transportation companies, by aggregating passenger travel data (e.g., counting passengers traveling from one region to another), can ana...

An electro-thermo-chemo-mechanical coupled computational framework for contact–dissolution corrosion using a phase-field formulation

Metallic contact interfaces in electrical connectors, microelectromechanical systems, and related components are commonly subjected to sustained mechanical loading, electrical conduction, thermal effects, and corrosive environments. The strong coupling between contact constraints...

Decentralized Solar-Driven Plant Factories Secure an Adequate Global Vegetable Supply beyond the Electricity Grid and Water Limitations

Abstract Conventional open-field vegetable production is increasingly constrained by climate volatility and natural resource endowments, creating supply instabilities and shortages that threaten global food resilience and human health. Here, we integrate solar photovoltaics and a...

Ferroptosis in liver biology and diseases.

Ferroptosis is a form of non-apoptotic cell death driven by iron-dependent lipid peroxidation (LPO). Ferroptosis is closely associated with hepatic metabolic pathways, particularly those involving iron, fatty acids, amino acids, and redox changes. This review aims to provide a co...

Red-Teaming Coding Agents from a Tool-Invocation Perspective: An Empirical Security Assessment

Coding agents powered by large language models are becoming central modules of modern IDEs. They help users to perform various complex coding tasks by invoking tools. Although powerful, tool-invocation operation in coding agents opens a substantial attack surface for adversaries....

Consensus recommendations for neurofibromatosis type 1 management in Asia Pacific

Neurofibromatosis type 1 (NF1) is a complex multisystem disorder requiring coordinated multidisciplinary care. This study aimed to develop consensus recommendations for NF1 management in the Asia-Pacific region. A modified Delphi process involving two survey rounds and a virtual...

Is “Knowing It’s Malicious” Enough? Evaluating LLMs for Fine-Grained Malware Behavior Auditing

Automated malware classifiers achieve strong detection performance, but auditing requires more than flagging a sample: analysts must explain malicious behaviors and justify them with concrete code evidence, a requirement that traditional signature-based methods and learning-based...

Towards On-Device Evidence Gathering for Intimate Partner Infiltration: A Feasibility Study for Joint Identity-Action Detection

Intimate Partner Infiltration (IPI) refers to phone-side privacy infiltration in intimate or close relationships, often enabled by physical access to a person's smartphone and discussed in technology-facilitated Intimate Partner Violence (IPV) contexts. Unlike conventional cybera...

Realization of Quantum Spin Hall Insulator Superlattice with Emergent Multigap‐Like Helical Edge States

ABSTRACT The functional quantum spin Hall insulators (QSHI), protected by time‐reversal symmetry against single‐particle backscattering, hold great promise for dissipationless quantum electronics. Realization of QSHI with gapped helical edge states, which would enable determinist...

Delaunay Weighted Two-sample Test for High-dimensional Data by Incorporating Geometric Information

Two-sample hypothesis testing is a fundamental problem with various applications, which faces new challenges in the high-dimensional context.To mitigate the issue of the curse of dimensionality, high-dimensional data are typically assumed to lie on a low-dimensional manifold.To i...

CRAFT: Exploring Wearable Creative AI on Smart Glasses for Fiction Writing in Real-World Contexts

Creative writing increasingly integrates AI assistance, yet current tools miss in-situ moments when writers draw inspiration from real-world experiences. We envision Context-aware Reality-Fiction Transformation ( CRAFT ), an approach for AI glasses that translates daily experienc...

Exfoliation of Molecular Crystals Enables Two-Dimensional Polymerization for Stable Photoelectric Response Devices

Two-dimensional polymers (2DPs) have emerged as a class of important materials with the unique advantages of an ultrathin, lightweight nature and a large accessible surface area, showing their promising potential in the area of optoelectronics, energy storage and conversion, and...

Managing Boundaries in Urban China: Nonprofit Social Work Agencies’ Strategies in Community Governance

Abstract Nonprofit social work agencies (NSWAs) play increasingly important roles in community governance by combining professional social work values with nonprofit organizational mandates. However, little is known about how these agencies manage organizational boundaries in sta...

DentalGEN: a large-scale controllable generative AI framework for automated dental crown restoration

Dental crown restoration addresses a global public health burden, yet is constrained by a slow, variable, and labor-intensive manual design process that limits access to high-quality treatment. Here we introduce DentalGEN, a large-scale controllable generative artificial intellig...

Molecular Machine‐Driven Fluorogenic Probes for Motion–Signal Conversion and Hydrophilicity Retention in Live‐Cell Nanoscopy

ABSTRACT Traditional fluorogenic and cell‐permeable molecular probes for live‐cell nanoscopy mainly rely on structural or hydrophilicity changes to generate intracellular fluorescence signals. Here, we introduce molecular machines into fluorogenic probe design. As a proof of conc...

The impact of an emergency department‐based advanced care unit on medical admissions, inter‐hospital transfers, and clinical outcomes for severe acute exacerbation of chronic obstructive pulmonary disease: A retrospective cohort study at North Lantau Hospital

Abstract Background North Lantau Hospital (NLTH) is a community hospital. The Emergency Medicine Advanced Care Unit (EMACU) was established to provide local critical care to unstable patients. Objective To evaluate the impact of EMACU on medical admissions and to compare outcomes...

Ecosocial environments and chronic lower respiratory disease mortality: a nationwide ecological study

Chronic lower respiratory disease (CLRD) is a leading cause of death in the United States and imposes a substantial economic burden. Ecosocial environments are closely linked to population health, yet nationwide evidence on their associations with CLRD mortality remains limited....

Assessing the Lagged Regional Economic Output Gaps After the 2015 South India Flood

ABSTRACT Natural hazards can adversely impact society, environment, and human well‐being. The development of mitigation strategies is typically based on estimates of economic losses, but such estimates are difficult when high‐resolution post‐disaster data are scarce. Models such...
