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...

A small molecule increases mycobacterial translation fidelity without a fitness cost by targeting ribosomal protein S5

A central dogma of molecular biology is the "speed-accuracy trade-off," where ribosomes must slow down to ensure accurate protein synthesis. In mycobacteria, a high basal level of mistranslation at glutamine and asparagine codons, caused by an indirect tRNA aminoacylation pathway...

Analytical and numerical solutions for the staged pressure filtration-electroosmotic dewatering process of slurry

High-water-content slurry is difficult to dewater efficiently because of its low permeability, high compressibility, and strong water retention, hindering construction-waste reduction and resource utilization. This study develops a staged analytical-numerical model for pressure f...

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...

Environmental Injection Attacks against GUI Agents in Realistic Dynamic Environments

Graphical User Interface (GUI) agents are increasingly deployed to interact with online web services, yet their exposure to open-world content renders them vulnerable to Environmental Injection Attacks (EIAs). In these attacks, an attacker can inject crafted triggers into a websi...

Efficient Grammar-Constrained Decoding via Parser Stack Classification

LLMs are widely used to generate structured output like source code or JSON. Grammar-constrained decoding (GCD) can guarantee the syntactic validity of the generated output, by masking out tokens that violate rules specified by a context-free grammar. However, the online computat...

Lookahead-Then-Verify: Reliable Constrained Decoding for Diffusion LLMs under Context-Free Grammars

Diffusion Large Language Models (dLLMs) have demonstrated promising capabilities and are increasingly used to produce formal languages defined by context-free grammars, such as source code and chemical expressions. However, as probabilistic models, they still struggle to generate...

Molecular Fingerprint-Dependent Retention and Fractionation of Combustion-Derived Dissolved Organic Matter on Kaolinite and Montmorillonite

Abstract The environmental fate of combustion-derived dissolved organic matter (CDOM) at clay mineral interfaces remains poorly understood. We applied FT-ICR-MS, XPS, and other techniques to investigate the interfacial behavior of CDOM from coal, charcoal, pinewood, and maize str...

Act2Intention: A Benchmark For Developing Active Mobile Agents Through Inferring User Intention from GUI Actions

Mobile GUI Agents powered by multimodal large language models (MLLMs) show promise in human-computer intelligence. However, current research primarily focuses on reactive task execution while lacking a comprehensive “understanding-prediction-execution” process for user intentions...

GUIA uditor : Enabling Post-hoc Child Safety Forensics via Action-Guided GUI Provenance on Mobile Devices

The proliferation of smart devices exposes children to online risks like grooming and financial scams that are deeply embedded within legitimate applications. Current approaches rely on automated prevention and detection, a paradigm that is fundamentally limited by its inherent f...

Earinter: A Closed-Loop System for Eating Pace Regulation with Just-in-Time Intervention Using Commodity Earbuds

Rapid eating is common yet difficult to regulate in situ, partly because people seldom notice pace changes and sustained self-monitoring is effortful. We present Earinter, a commodity-earbud-based closed-loop system that integrates in-the-wild sensing, real-time reasoning, and th...

AuthGlass: Benchmarking Voice Liveness Detection and Authentication on Smart Glasses via Comprehensive Acoustic Features

With the rapid advancement of smart glasses, voice interaction has been widely adopted due to its naturalness and convenience. However, its practical deployment is often undermined by vulnerability to spoofing attacks, while no public dataset currently exists for voice liveness d...

Selective Adsorption of Methyl Acetate from Model Fischer–Tropsch Synthetic Oil on 13X Zeolite: Experimental and Computational Insights

Abstract The efficient removal of ester oxygenates from Fischer–Tropsch (FT) synthetic oil remains challenging due to limited understanding of selective adsorption mechanisms and adsorption kinetics. Herein, a combined experimental and theoretical approach was employed to investi...

Towards Wearable Opportunistic Crowdsensing for Open-Vocabulary Activity Data Collection Through User-Scheduled Trigger-Action Routines

Collecting richly labeled wearable activity data in everyday settings remains difficult because retrospective annotation is costly and often imprecise. Prior data collection apps rely on a labor-intensive self-reporting strategy and primarily treat participants as crowd labelers....

JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova

Abstract We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from ∼2 weeks before to ∼1 yr after maximum light. JWST near- and mid-infrared spectra at +276 and +363 days show ∼400 K dust emission that cools by ∼75 K between epochs, the first una...

PPG as a Bridge: Cross-Device Authentication for Smart Wearables with Photoplethysmography

As smart wearable devices become increasingly powerful and pervasive, protecting user privacy on these devices has emerged as a critical challenge. While existing authentication mechanisms are available for interaction-rich devices such as smartwatches, enabling on-device authent...

Phase-dependent high-temperature oxidation behavior of multiphase Ti2AlNb alloy

Environmental degradation of Ti 2 AlNb alloys is intrinsically coupled with their multiphase constitution, yet the local mechanisms by which individual phases mediate oxidation remain insufficiently resolved. Here, we reveal the phase-selective high-temperature oxidation behavior...

Unraveling the mechanism of programmable heating and quenching in enhancing tar yield from PVC pyrolysis: a ReaxFF MD study

The conventional continuous heating (CCH) method for recovering polyvinyl chloride (PVC) has limitations that result in a low tar yield. The programmable heating and quenching (PHQ) method can increase the tar yield of PVC, but the underlying mechanism was still unclear. In this...

Beam layout design in shear wall structures using a diffusion model guided by rule-based masks

Serving as critical load supports and transfer components in shear wall structures, beams require layout designs that balance mechanical rationality with architectural functionality constraints. Conventional design methods, which rely on engineers' expertise, are challenging to s...
