Experimental and numerical investigations on methods for improving impact performance of precast segmental bridge piers

Precast segmental bridge piers (PSBPs) are increasingly used in accelerated bridge construction. However, segmental joints and bottom segments are more vulnerable to severe damage under impact loads. This study experimentally and numerically investigates three retrofitting method...

Resilient train formation control for ASVs under intermittent communication environment via actor–critic reinforcement learning

To address the train formation task of autonomous surface vehicles (ASVs) operating under intermittent communication environment, this paper investigates the problem of resilient formation robust control for ASVs. First, a resilient distributed leader predictor (RDLP) is designed...

Velocity adaptive preview path tracking control for autonomous vehicles using deep reinforcement learning with Lyapunov function-based reward shaping

Traditional rule-based path tracking controllers of autonomous vehicles (AVs) often struggle with nonlinear vehicle dynamics, parameter tuning, and changes in road conditions. Learning-based methods partly address these issues, but remain limited in adapting to velocity changes,...

Hydrogel-Based Sensors for Foodborne Pathogen Detection: Tackling Matrix Interference Through Anti-Fouling and Smart Design Strategies

Significant progress has been made in hydrogel-based biosensors, yet food matrix interference remains underexplored. Previous reviews largely focused on material properties and signal amplification, while systematic understanding of interference mechanisms and mitigation strategi...

The relationship between digital health literacy and short-form video addiction among university students: the sequential mediating role of physical activity and self-control

This study examined the association between digital health literacy (DHL) and short-form video addiction (SVA) among university students. It also examined potential indirect associations through physical activity (PA) and self-control (SC). A cross-sectional survey design was ado...

Tuning Upconversion through Ho3+/Nd3+ Co-sensitized Cascade Energy Transfer

Abstract Lanthanide-doped upconversion nanocrystals (UCNCs) have attracted significant interest, driven by their emerging applications in photonics and anticounterfeiting. However, conventional UCNCs are excited by 808, 980, or 1540 nm, and there remains a gap within the 808–980...

Beyond resistance: an integrated psychological organizational model of employee response to digital transformation

Organizational competitiveness increasingly depends on successful digital transformation, yet employee resistance remains a critical barrier. This study develops an integrated framework grounded in Innovation Resistance Theory and Social Cognitive Theory to investigate key driver...

How Do Information Content and Language Style Relate to Disaster Information Dissemination? The Moderating Role of User Involvement

Social media has become an important channel for information exchange during sudden disasters, with implications for both public-sector communication and corporate risk communication. However, limited research has examined how substantive message content and linguistic presentati...

Manipulatable Cascade Pumping Single-Photon Upconversion

Photon upconversion (UC), while promising for infrared photonics, is fundamentally constrained by limited spectral response range, low efficiency, and slow response speeds. Here, we present a machine learning-guided single-photon UC strategy based on cascade pumping that implemen...
