Experimental and numerical investigation of ignition effects on explosion temperature fields in residential buildings

This study systematically investigates the temperature evolution characteristics of methane explosions in a full-scale residential building under various ignition scenarios through a combined approach of full-scale experiments and CFD simulations. A 280 m 3 full-scale experimenta...

Frequency-specific structure-function decoupling underlies core symptoms in schizophrenia

A major challenge in schizophrenia is its clinical heterogeneity, which has obstructed biomarker identification. Recent research indicates that frequency-specific structural eigenmodes, which govern distinct spatiotemporal propagation patterns, are linked to the functions of unim...

Superconducting Hydride Mg2RhH6 Experimentally Achieved at Lower Pressure

Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressure...

Water Vapor Adsorption Behavior Evolution of MarineKerogen across Maturity from Carbonization to Graphitization Stages:New Insights Based on Thermodynamic and Kinetic Characterization

Abstract The water adsorption behavior of marine overmature kerogen is a theoretical foundation for the shale gas exploration and development and CO2 geological sequestration. However, this issue remains poorly understood, especially regarding graphitization effects. This study i...

Long-memory and cyclical link prediction in temporal social networks

<title>Abstract</title> Temporal social networks contain persistent tie activation and periodic communication rhythms, but most link prediction models either emphasize short-term recurrence or rely on black-box embeddings that offer no interpretable summary of temporal structure....

Machine-learning-based model for predicting surface impedance of microslit panels in grazing flow

Accurately predicting the acoustic properties of noise-reduction materials in real-world, flow-exposed environments remains a significant challenge in engineering. Classical models of microslit panels are unsuited for grazing flow conditions due to complex, nonlinear flow-acousti...

Altitude-dependent role of nitric acid in iodic acid-iodous acid nucleation: from marine boundary layer catalyst to upper troposphere core component

Abstract. With global sulfur emissions declining and concurrent marine iodine emissions rising, new particle formation (NPF) driven by iodic acid (HIO3) and iodous acid (HIO2) has become critical to global aerosol and cloud condensation nuclei (CCN) budget. However, the role of u...

Multisensory Biophilic Experience in Virtual Retail Interiors: Effects of Visual and Auditory Stimuli on Visual Attention and Emotion

Advances in digital technology have facilitated the integration of biophilic design principles into retail interiors, presenting new opportunities to enhance consumer experiences. This study examines the impact of multisensory biophilic stimuli, specifically visual and auditory e...

Superconductivity from doping symmetric mass generation insulators: application to La3Ni2O7 under pressure

Abstract We investigate the bilayer nickelates as a platform to realize the symmetric mass generation (SMG) insulator, a featureless Mott insulator that arises due to the Lieb-Schultz-Mattis (LSM) anomaly cancellation in bilayer spin-1/2 lattice systems. Through a single-orbital...

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

ABSTRACT Biohybrids promise to endow photosynthetic organisms with new or enhanced functions, yet most operate monofunctionally, targeting either photosynthesis enhancement or stress tolerance, and cannot report environmental changes. Here, we develop an environmentally responsiv...

In vivo labeling–based proteomic analysis of early follicle oocytes and cisplatin-induced alterations in mice

Abstract A systematic proteomic profile of oocytes from early-stage follicles, particularly primordial follicles, is critical to protect female reproductive capacity in the context of chemotherapy, yet progress has been hindered by the rarity of oocyte samples and technical chall...

Quantifying the Correlation Between Capacity Utilization and Electrolyte Dosage for Ultrahigh‐Energy‐Density 769 Wh Kg −1 Rechargeable Lithium Metal Batteries

ABSTRACT The pursuit of high‐energy‐density lithium metal batteries requires simultaneous optimization of electrode architecture, electrolyte formulation, and interfacial stability. Here, we establish a fundamental parameter g(σ e , D e ) that quantifies the relationship between...

Isotropic-carrier-transport perovskite single crystal enables high-photoresponsivity solar-blind photodetectors for selective flame monitoring

Low-dimensional halide perovskites are promising candidates for solar-blind ultraviolet photodetectors. However, simultaneously achieving high photoresponsivity and low dark current remains challenging, due to the restricted transport and collection of photogenerated carriers cau...

Peptide language pragmatic analysis and two-stage hierarchical learning framework for therapeutic peptide prediction

Therapeutic peptides exert pivotal effects in diverse biological processes, and have attracted significant interest in the field of biomedicine in recent years. However, most existing methods often fail to adequately capture the intricate interactions among amino acid residues an...

From making to judging: Art education in the AI era

Art creation becomes almost effortless with Generative AI. However, a bigger challenge arises at the heart of creativity: assessing the quality of what is produced and remaking it accordingly. This essay argues that the truly scarce and teachable skill in art education is not mer...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets
