Intelligent vehicle lateral control strategy research based on feedforward + predictive LQR algorithm with GA optimisation and PID compensation.

Targeting the lateral motion control problem in the intelligent vehicle autopilot structural system, this paper proposes a feedforward + predictive LQR algorithm for lateral motion control based on Genetic Algorithm (GA) parameter optimisation and PID steering angle compensation. Firstly, based on the vehicle dynamics tracking error model, the intelligent vehicle LQR lateral motion controller as well as the feedforward controller are designed, and upon which the predictive controller is added to eliminate the system lag.Subsequently, exploiting the advantage that the PID algorithm is not model-based, a PID steering angle compensation controller that can directly control and correct the lateral error is designed.

A Case of Nosocomial Coinfection of SARS-CoV-2 and Influenza A Virus in a Hospitalized Patient with Acute Myocardial Infarction.

Background: Inpatients in cardiovascular medicine departments often have complicated conditions, long hospital stays, and a high risk of nosocomial infection. Good infection control is of great importance for the treatment and rehabilitation of inpatients in cardiovascular medicine departments.

Methods: We report a case of coinfection with the 2019 novel coronavirus (SARS-CoV-2) and influenza A virus in a hospitalized patient with acute myocardial infarction.

NiFe/BC nanocatalysts based on biomass charcoal self-reduction achieves excellent hydrogen storage performance of MgH.

Bimetallic catalysts offer unique advantages for improving the hydrogen storage performance of MgH. Herein, NiFe/BC nanocatalysts were prepared a simple solid phase reduction method using a low-cost biomass charcoal (BC) material as the carrier. The onset temperature of hydrogen release for the MgH + 10 wt% NiFe/BC composite was 184.

Two Cases of Pseudoelevation of Plasma D-Dimer Levels.

Background: D-dimer is a molecular marker of fibrin degradation and fibrinolytic system activation and is an effective indicator for early diagnosis of thrombotic diseases, monitoring of thrombolytic therapy, and efficacy evaluation; therefore, the accuracy of D-dimer test results is of great significance to the diagnosis and treatment of diseases in clinical practice.

Methods: This paper reports two cases of pseudoelevation of plasma D-dimer levels by different test systems.

Results: In case 1, the abnormal increases in the results of the ACL TOP 700 analyzer were considered to be the pseudoelevation caused by interferences, and the abnormal increases in the STA-R Max results were considered to be the pseudoelevation caused by interferences in case 2.

Clinical value of serum trophoblast cell surface protein 2 (TROP2) antibody in non-small-cell lung cancer patients.

Objective: This study was to explore the clinical role of serum trophoblast cell surface protein 2 (TROP2) antibody in patients with non-small-cell lung cancer (NSCLC).

Materials And Methods: We collected serum specimens from 117 NSCLC patients, 40 benign lung disease patients, and 60 healthy controls. TROP2 antibody concentrations were measured using enzyme-linked immunosorbent assay.

Combined measurement of CA 15-3 with novel autoantibodies improves diagnostic accuracy for breast cancer.

Objective: CA 15-3 is a traditional biomarker for advanced breast cancer with limited sensitivity for early stage patients. In order to increase the sensitivity for early detection, in this study, we introduced novel tumor-associated autoantibodies that were measured concurrently with serum CA 15-3 to evaluate their diagnostic advantage in breast cancer.

Methods: We investigated a T7 breast cancer complementary deoxyribonucleic acid (cDNA) phage library for tumor-associated antigens using sera from normal and breast cancer patients.
