Dark heritage tourism education: effects of information-led versus narrative-led advertising appeals on tourists’ heritage preservation intentions

In dark cultural heritage communication, eliciting empathy does not necessarily translate into preservation actions. Dark cultural heritage is both educational and sensitive: communication needs to reduce audiences’ psychological distance and facilitate understanding and commemor...

Resolving closely spaced corners using second order Gaussian directional derivatives

Corner detection is a fundamental step in many computer vision tasks, including image matching and 3D reconstruction. However, closely spaced corners are difficult to distinguish because inappropriate smoothing scales may cause the filtered responses of neighboring structures to...

Effects of Unilateral Versus Bilateral Training on Physical Performance Outcomes in Team Sport Athletes: A Systematic Review and Meta-Analysis

Objective: This systematic review and meta-analysis evaluated the comparative effects of unilateral versus bilateral training on physical performance outcomes relevant to team sport athletes. The review addresses strength, power, speed, agility, reactive strength, and core stabil...

A multi-task deep learning network for robust and high accuracy star sensor image centroiding

Star sensors require reliable onboard centroid estimation despite binary-star interference and non-Gaussian distortions. Conventional algorithms lack robustness, while deep learning models often sacrifice accuracy or computational efficiency for real-time operation. This study pr...

Efficient ISAR imaging of ship-ocean scenes using improved bidirectional ray tracing with BVH acceleration

This paper proposes an improved bidirectional ray tracing algorithm based on BVH (Bounding Volume Hierarchy) acceleration for ISAR imaging of complex ocean scenes. The proposed method was employed to obtain the frequency-domain electromagnetic scattering characteristics of compos...

Verifying Interrupt-driven Programs Efficiently via Heuristic and Reduced Partial-order Constraints

Interrupt-driven programs are extensively utilized in embedded systems for safety-critical domains. However, uncertain interleaving executions of enabled tasks with different priorities often lead to concurrency defects. In this context, assertion violation detection is a fundame...

Economic Consequences of Environmentally Sustainable Improvements for Corporate Liquidity in Emerging Markets

This study examines the association between environmentally sustainable improvements and corporate liquidity in BRICS economies. Using a panel of non-financial firms from 2010 to 2022, the study considers both the pre-COVID-19 period and the post-COVID-19 period. Environmental im...

Comments on “Adaptive Finite‐Time Cooperative Platoon Control of Connected Vehicles Under Actuator Saturation”

ABSTRACT This brief paper points out a serious flaw in the development of the controller of [“Adaptive finite‐time cooperative platoon control of connected vehicles under actuator saturation,” Asian Journal of Control 24 (2022): 3552–3565], making the proposed approach therein un...

A Defect Detection Method for Rail Ultrasonic B-Scan Images Based on a Multi-Scale Dense Attention Network

Rail internal defects pose significant threats to railway operational safety, and ultrasonic B-scan imaging provides an effective nondestructive testing approach for visualizing subsurface rail conditions. However, manual interpretation of B-scan images is time-consuming and depe...

Longitudinal brain dynamics and prediction of craving changes in individuals with methamphetamine use disorder

Abstract Individuals with methamphetamine use disorder (MUD) exhibited functional and structural brain recovery during abstinence. However, longitudinal neural changes of large-scale brain networks after prolonged abstinence remain unclear. Here, energy landscape analysis was app...

Identification of differential topologically associating domains from low sequencing depth and pseudo-bulk chromatin contact maps

Topologically associating domains (TADs) are fundamental units of 3D genome architecture that shape gene regulation. Comparative analyses of TADs across biological conditions have revealed their involvement in development and disease. However, accurately identifying differential...

Authentication and key agreement scheme based on PUF and Chebyshev chaotic map for blockchain-enabled UAV networks

Abstract Aiming at the security issues of open channel vulnerability, limited node resources, and single-point failure caused by centralized authentication in unmanned aerial vehicle (UAV) swarm networks, this paper proposes an authentication and key agreement scheme integrating...

Quasi-Vertical GaN-Based Trench Gate MOSFETs Treated with Fluorine-Plasma

In this paper, a quasi-vertical GaN-based trench gate MOSFETs treated with F-plasma is proposed. The F-plasma-treated devices exhibit a breakdown voltage (Vbr) increased from 170 V to 275 V compared to the untreated devices. TCAD simulations reveal that F-plasma treatment signifi...

VARE: Geometry-Anchored Bearing and Range Stabilization for USV Recovery
