Emotional interactive experiences in different environments and cultures: machine learning-based electrocardiogram analysis of the emotional elicitation effect in augmented reality

Emotions are dynamic feedback mechanisms by which individuals respond to external stimuli, and the environment profoundly influences their changes. Therefore, it is necessary to incorporate healing and inclusive considerations into public environmental design. This study combines...

Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation

ABSTRACT Indole oxidation reaction is a pivotal process in organic chemistry, playing a crucial role in the synthesis of various natural products and pharmaceuticals. To‐date, indole oxidation is limited to heme enzymes and synthetic iron porphyrin compounds. Herein, we demonstra...

Waltz: Temperature-Aware Cooperative Compression for High-Performance Compression-Based CSDs

Data compression is widely adopted for modern solid-state drives (SSDs) to mitigate SSD lifetime issues. Researchers have proposed compression schemes at different system layers, including device-side solutions like CCSDs ( c ompression-based c omputational S SD s) and compressio...

Multifunctional Double-Network Hydrogel Synergistically Enhanced by Zirconium Ions and Carbon Quantum Dots

Abstract Inspired by the intuitive and efficient information-sensing capability of colorimetric changes, this work presents a design strategy that integrates fluorescent carbon quantum dots (CDs) with metal ion coordination to simultaneously enhance mechanical robustness and mult...

Hepatitis B surface antigen clearance rate with pegylated interferon-α therapy in different chronic hepatitis B virus infection populations: A systematic review and meta-analysis

BACKGROUND: Chronic hepatitis B virus (HBV) infection is an urgent public health issue, particularly in endemic regions of Asia and sub-Saharan Africa. Achieving hepatitis B surface antigen (HBsAg) clearance significantly reduces the risk of hepatocellular carcinoma. Pegylated in...

Infrared temperature gradient microstructure mapping for optimizing filler dispersion in oriented h-BN/Al2O3/PDMS thermal interface materials

High-performance thermal interface materials require continuous heat-conduction networks, whereas filler agglomeration can disrupt heat transport and cause nonuniform heat dissipation. For h-BN/polymer composites, direct visualization of filler dispersion is challenging because o...

Cascading risks in the global nickel supply chain and their implications for battery-based electrification

Global electrification is rapidly increasing nickel demand because of its role in nickel-rich battery chemistries. Yet the systemic vulnerabilities of the global nickel supply chain and their implications for battery-related electrification remain insufficiently understood. Here,...

Phase‐Controlled Bi 2 O 3 Nanosheets for Highly Efficient Electrochemical CO 2 Reduction to Formate

ABSTRACT The electrochemical carbon dioxide reduction reaction (CO 2 RR) offers a sustainable route to convert CO 2 into valuable chemicals, with formic acid being one of the most economically attractive products. Bismuth (Bi)‐based materials have shown promise as CO 2 RR electro...

Language-enhanced generative modeling for amyloid PET synthesis from MRI and blood biomarkers.

Assessment of amyloid pathology in Alzheimer's disease (AD) often relies on amyloid-beta positron emission tomography (Aβ-PET), but its clinical use is limited by cost and accessibility. We developed a language-enhanced generative framework to synthesize Aβ-PET images from T1-wei...

Improving Quantum-ChemicalPrediction of 19F NMR Chemical Shifts via Machine Learning

Abstract 19F nuclear magnetic resonance (NMR) spectroscopy is widely used for structural elucidation of fluorinated molecules, but reliable prediction of 19F chemical shifts remains challenging because quantum-chemical calculations are computationally demanding and their accuracy...

Electron transfer kinetics and molecular structural basis of dissolved black carbon as an electron shuttle

Dissolved black carbon (DBC) serves as a crucial electron shuttle in various biogeochemical cycles owing to its highly mobile and redox-active nature. Prior work on DBC electron-shuttling has focused on thermodynamic metrics—electron donating capacity (EDC) and electron accepting...

stDSVA: spatial transcriptomics deconvolution with a semi-supervised framework and cell type variation analysis

Spatial transcriptomics (ST) integrates transcriptomic profiling with tissue architecture, enabling the investigation of spatial heterogeneity in gene expression within intact tissues. However, due to the limited resolution of many current ST platforms, computational deconvolutio...

Occupational identity, competence dimensions, and psychological well-being among Chinese public security personnel: a cross-sectional path analysis

Police personnel are exposed to substantial occupational stress, yet less is known about how occupational identity and different dimensions of occupational competence are associated with psychological well-being. This study examined the direct associations of occupational cogniti...

Bridging the GapBetween Laboratory Catalyst Researchand Practical Water Electrolyzer Commercialization

Abstract Water electrolyzers are key technologies for enabling a carbon-neutral society by facilitating sustainable hydrogen production. Despite extensive efforts to develop highly active catalysts, a persistent gap remains between catalyst performance evaluated in rotating disk...

Aero-DETR: a frequency-adaptive sparse-interaction network for UAV-assisted aircraft surface defect detection

Abstract Aircraft surface defect inspection is critical for aviation safety but remains challenging because defects in unmanned aerial vehicle (UAV) imagery are often small, low-contrast, and multi-scale. We construct the aircraft UAV defect inspection dataset (AUDID), containing...

STELT: A spatiotemporal deep learning framework for diffusion-ordered NMR spectroscopy reconstruction with artifact suppression

Diffusion Ordered NMR Spectroscopy (DOSY) is a powerful technique for studying mixtures by probing the diffusion behavior of mixed compounds and enabling their identification and separation in mixture samples. The performance of DOSY generally relies on the adopted reconstruction...

Persistent Shelf‐to‐Basin Export of Bioavailable Dissolved Organic Carbon in the Arctic Ocean

Abstract Microbial carbon demand often exceeds local primary production in the oligotrophic central Arctic Ocean. Whether shelf‐derived dissolved organic carbon (DOC) provides a persistent carbon subsidy to reconcile this imbalance remains unclear. Here, we combine amino acid‐bas...
