Right coronary sinus of Valsalva pseudoaneurysm after a motorcycle accident: A case report.
Medicine (Baltimore)
January 2025
Department of Radiology, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.

Highway guardrails are critical safety infrastructure along roadways, designed to redirect vehicles back into their lanes and facilitate a gradual deceleration to a complete stop. Traditional highway steel guardrails exhibit significant limitations, including inadequate energy absorption, susceptibility to corrosion, and an increased risk of vehicles leaving the roadway during severe collisions. Furthermore, the production and transportation of these guardrails contribute to substantial carbon emissions and environmental pollution.

PLoS One

School of Energy Science and Engineering, Henan Polytechnic University, Jiaozuo, Henan, China.
In order to obtain proper speed limits in expressway work zones, CarSim and TruckSim software were used to determine the critical car and truck safe speeds and then VISSIM software was used to determine the traffic capacities and their corresponding speed limits under different upstream transition area lengths and road adhesion coefficients. The results show that critical car and truck safe speeds increase exponentially while traffic capacity and its corresponding speed limit increase logarithmically with rising road adhesion coefficient under a constant upstream transition area length, and critical car and truck safe speeds increase as a power function while traffic capacity and its corresponding speed limit increase exponentially with rising upstream transition area length under a constant road adhesion coefficient. Because Road Traffic Signs and Markings- Part 4: Work Zone (RTSM, GB 5768.

Sci Eng Ethics
January 2025
Department of Philosophy and Religious Studies, North Carolina State University, Raleigh, NC, USA.
The incorporation of ethical settings in Automated Driving Systems (ADSs) has been extensively discussed in recent years with the goal of enhancing potential stakeholders' trust in the new technology. However, a comprehensive ethical framework for ADS decision-making, capable of merging multiple ethical considerations and investigating their consistency is currently missing. This paper addresses this gap by providing a taxonomy of ADS decision-making based on the Agent-Deed-Consequences (ADC) model of moral judgment.

Methods: Forty-eight patients with unstable distal radius fractures between January 2022 and February 2023 were retrospectively analyzed and divided into the CO external fixation group and internal fixation group. CO external fixation group consisted of 25 patients, including 7 males and 18 females, aged from 37 to 56 years old with an average of ( 52.
