A compact, wireless fluorimeter system for continuous, real-time monitoring of tissue perfusion via in vivo fluorescence signals

In vivo fluorescence signals provide physiological and pathological insights for the interpretation of biological states associated with anatomical abnormalities or disease. Conventional methods for measuring fluorescence signals rely on bulky, costly instrumentation for imaging...

A dual-path trust–risk model of GenAI continuance: Conversational attributes, psychological evaluations, and configurational patterns

The rapid advancement of generative artificial intelligence (GenAI) has transformed human–AI interaction by enabling more efficient, flexible, and conversational forms of user support. To better understand users' continuance intention, this study draws on the post-adoption satisf...

Impact of Polyimide Semi-Interpenetrating Polymer Networks on the Physicochemical Properties of Vulcanized Acrylonitrile–Butadiene Rubber

This work demonstrates the physicochemical property changes of composite thermoset elastomers prepared by incorporating mechanically and thermally stable polyimide (PI) into vulcanized acrylonitrile butadiene rubber (NBR) through a semi-interpenetrating polymer network (semi-IPN)...

Homogeneous growth of self-assembled Si nanopillar array via an asymmetric overlap of a spot beam laser

Nanosecond ultraviolet (UV) laser irradiation of Si thin films with a Gaussian beam was employed to study the transition from laser-induced periodic surface structures (LIPSS) to nanopillar formation. Single-pulse irradiation produced concentric modification regimes, ranging from...

Criteria for unbiased estimation: applications to noise-agnostic sensing and quantum channel estimation

We establish the necessary and sufficient conditions for local unbiased estimation in multi-parameter estimation tasks. More specifically, we first consider quantum state estimation, where multiple parameters are encoded in a quantum state, and derive simple and intuitive necessa...

The Impact of Medicaid Managed Long-Term Services and Supports on Nursing Home Staffing and Care Diversion: A Staggered Difference-In-Differences Approach

State governments have increasingly adopted Medicaid managed long-term services and supports (MLTSS) programs. Drawing on data from nursing homes in six states that implemented mandatory statewide MLTSS between 2010 and 2014, this study examines MLTSS impacts on care diversion an...

Mapping the nuclear environments of extreme coronal line emitting galaxies

Abstract Extreme coronal line emitters (ECLEs) are a rare class of galactic nuclei exhibiting unusually strong high-ionisation forbidden emission lines, and several ECLEs have been linked to tidal disruption events (TDEs). In this work, we compile and analyse optical spectra of 3...

Human milk-derived Limosilactobacillus reuteri improved growth performance of weaned pigs by modulating systemic immune responses and enhancing intestinal health

This study aimed to evaluate the effects of dietary supplementation of human milk-derived Limosilactobacillus reuteri (REU) on growth performance, frequency of diarrhea, and systemic and intestinal health parameters of weaned pigs. Dietary supplementation of REU had greater (P =...

Multi-objective optimization of desiccant wheel performance using adaptive sampling and SHAP analysis

Design optimization of desiccant wheel-based dehumidification systems requires performance data that sufficiently cover a high-dimensional design space. However, obtaining such data through conventional design of experiments is burdensome because experiments and repeated high-fid...

Towards a universal ovarian cancer biomarker model: clinical validation of Trx1 and CA125 dual strategy

Abstract Background Ovarian cancer is the fifth leading cause of cancer-related mortality in women, with early detection being critical for improving patient outcomes. Current diagnostic biomarkers, including Cancer antigen 125 (CA125), human epididymis protein 4 (HE4), and their...

Effect of pre-emptive operational strategies on product quality and deterioration dynamics

The innovative logistics strategy of cross-docking enables the offloading of goods from incoming vehicles at the receiving dock, followed by loading the products into outgoing trucks, eliminating the need for prolonged product storage. The brisk movement of products within the cr...

Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
