Exploring autonomous vehicle crash risk: system coupling effects and key causal factors.

Introduction: The continuous progression of autonomous driving technology is propelling the automotive industry into an unprecedented era, with the intelligence and driving safety capabilities of autonomous vehicles serving as crucial benchmarks for assessing industry development. However, crashes involving autonomous vehicles have raised concerns among both government authorities and the general public regarding this technology. Consequently, conducting a comprehensive analysis of crash causes and key causal factors holds immense significance for technological progress, personnel safety, and shaping the future direction of the automotive industry.

Using microplastic-carbon to reassess pollution level of microplastics in urban rivers.

Environmental microplastics (MPs) are challenging to compare due to non-harmonized sampling and quantification methods. As MPs are predominantly composed of recalcitrant organic carbon (OC), they contribute to the total organic carbon (TOC) pool in environments. The concentration of recalcitrant carbon in microplastics (MPC) can theoretically serve as a complementary, standardized mass-based index to characterize MPs pollution levels.

Full Characterization of Genuine 17-qubit Entanglement on the Superconducting Processor.

We present a least square state estimator regularized by state purity to accomplish the task of quantum state tomography and entanglement verification, and report an experimental validation on a superconducting processor. First, a scalable full-state tomography is achieved with state fidelity 0.8217(1) for the 9-qubit W state and 0.

The Systemic Immune-Inflammation Index Predicts Long-Term Outcomes in Patients With Unstable Angina and Diabetes After Revascularization.

Background: The incidence of unstable angina (UA), a type of cardiovascular disease (CVD), has increased in recent years. Meanwhile, timely percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA) procedures are crucial for patients with UA who also have diabetes mellitus (DM). Additionally, exploring other factors that may influence the prognosis of these patients could provide long-term benefits.

Coagulation Disorders in Patients With Acute Respiratory Distress Syndrome Following Acute Aortic Dissection: A Prospective Observational Study.

Background: Coagulation disorders are potentially one of the most important pathogeneses of acute respiratory distress syndrome (ARDS) following acute type A aortic dissection (ATAAD). This study aimed to determine whether aortic dissection singularly and cardiopulmonary bypass (CPB) surgery can activate coagulation pathways, promoting ARDS development in patients with ATAAD.

Methods: A total of 450 patients who received treatment at Beijing Anzhen Hospital, Capital Medical University, between March 2023 and February 2024 were consecutively enrolled in this prospective cohort study.
