Short-term thermal dynamics in single U-tube borehole heat exchangers: an unbalanced trade-off between coefficient of performance and delivered energy under variable flow rate operation

Variable-speed circulation pumps are common in ground-source heat pump (GSHP) installations, but the short-term response of borehole heat exchangers (BHEs) to variable flow is poorly resolved: line-source methods omit the in-borehole thermal capacity, and thermal-resistance-capac...

The assembly pathway for human papillomavirus L1 capsid protein is encoded in electrostatic interactions

Human papillomavirus L1 protein spontaneously folds and assembles into 60 nm virus-like particles (VLP), with T = 7d icosahedral symmetry at high salt concentrations but not in low salt. Rapid increase from low to high salt during the assembly process gives poor-quality VLPs, whi...

Characterization of Formation Deformation during Production Test from Gas Hydrate in Alaska: A Distributed Fiber Optic Sensing Approach

Abstract Reliable monitoring of geomechanical responses is essential for the safe and sustainable production of gas hydrate reservoirs. This study reports the first field-scale application of distributed strain sensing (DSS) during a 10 month extended gas production test on Alask...

Self-Assembly of Ordered Pt Complexes with Bidentate Ligands from Solution onto Graphite Surfaces

Abstract Metal–ligand coordination offers a versatile platform for programming on-surface nanostructures with well-defined geometries and tunable coordination environments that are directly relevant to the design of ligand-stabilized single-atom catalysts. While numerous studies...

PDSVF: Prompt-driven SAM-Med2D with parallel ViT and state-space fusion for skin lesion segmentation

Accurate segmentation of skin lesions in dermoscopic images underpins computer-aided diagnosis of skin cancer. The task is difficult: lesions show blurred, low-contrast boundaries, vary widely in scale, shape, and color, and are often obscured by hair and other imaging artifacts....

Investigating the Overburden Correction Factor (Kσ) in silty sand using centrifuge modeling

This study involves a comprehensive series of four centrifuge experiments, designed to closely simulate a 5-m-thick layer of silty sand subjected to a range of drainage conditions—both single and double—and exposed to effective overburden pressures of approximately 100 and 600 kP...

Quantifying immunosuppressive barriers using a mathematical framework of tumor-associated myeloid cell mediated resistance in oncolytic virotherapy

Oncolytic virotherapy (OVT) represents a promising frontier in oncology, utilizing engineered viruses to selectively lyse malignant tumor cells while simultaneously triggering a systemic anti-tumor immune response. However, the therapeutic efficacy of OVT is frequently hampered b...

Reproducibility, Replicability, and Research Quality in Homogeneous Catalysis

Abstract Researchers from all sectors of homogeneous catalysis convened in response to concerns regarding reproducibility in science to analyze the issue and provide recommendations. In addition to an in-person workshop, the group engaged the broader homogeneous catalysis communi...

Global waste trade: Comparative advantage, the pollution haven effect, and externality costs

Abstract I quantify how comparative advantage and the pollution haven effect (PHE) shape international waste flows and infer the associated externality costs by constructing a Ricardian model with generation, trade, and use as a production input of waste. Combining waste flow, ta...

ReDON: Recurrent Diffractive Optical Neural Processor with Reconfigurable Self-Modulated Nonlinearity

Diffractive optical neural networks (DONNs) have demonstrated unparalleled energy efficiency and parallelism by processing information directly in the optical domain. However, their computational expressivity is constrained by static, passive diffractive phase masks that lack eff...

Somatic, Psychiatric and Neurodevelopmental Comorbidities in People with Autism Spectrum Disorder (ASD): A Narrative Review

Background/Objectives: Autism spectrum disorder (ASD) is currently singularly described as a behaviourally defined neurodevelopmental diagnosis with symptoms affecting social communication and social understanding alongside the presence of restricted patterns of behaviour. Wide,...

SKYLIGHT: A Scalable Hundred-Channel 3D Photonic In-Memory Tensor Core Architecture for Real-time AI Inference

The growing computational demands of artificial intelligence (AI) are challenging conventional electronics, making photonic computing a promising alternative. However, existing photonic architectures face fundamental scalability and reliability barriers. This paper introduces SKY...

Adaptive drop-deployable visible light communication-based underwater sensing probe

Covering under 0.1% of the ocean’s surface, coral reefs support about 30% of all marine life. Nevertheless, this fragile ecosystem is experiencing an extinction threat due to overexploitation and anthropogenically driven pressure. High-frequency and widespread observations are es...

A game-theoretic attack-defense framework for the study of network resilience

The rapid evolution of communication technologies and the Internet of Things has enhanced system interconnectivity, allowing localized disruptions to cascade into failures. Many such breakdowns are not purely accidental but emerge from intentional countermeasures that influence o...
