Traditional Chinese Medicine Strategy for Patients with Tourette Syndrome Based on Clinical Efficacy and Safety: A Meta-Analysis of 47 Randomized Controlled Trials. [PDF]

Biomed Res Int, 2021
Objective. Although increasing evidence reveals the efficacy of traditional Chinese medicine (TCM) and its safety on Tourette Syndrome (TS) patients, whether TCM is indeed improving TS remains unclear. The purpose of the current study is to perform a meta‐analysis to evaluate the efficacy and safety of TCM on treating TS patients. Method.

Hydrologic Controls on Individual Ostracode Stable Isotopes in a Desert Lake: A Modern Baseline for Lake Turkana

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 5, May 2023., 2023
Abstract Stable carbon (δ13C) and oxygen (δ18O) isotope measurements in lacustrine ostracodes are widely used as paleolimnological indicators of past climate change. Previous work has used individual ostracode valves to resolve seasonal and subdecadal paleohydrological signals, yet replicated assessments of co‐occurring specimens from modern samples ...

Multiobjective Synchronous Control of Heavy‐Duty Vehicles Based on Longitudinal and Lateral Coupling Dynamics

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
The steering system, suspension system, and braking system of the vehicle are interrelated, so the ride comfort and handling stability of the vehicle are also closely related. But the vertical and lateral dynamics equations and controls system of the vehicle are always independent of each other, and the multiobjective control is generally achieved ...

Ecological cooperative adaptive cruise control of over‐actuated electric vehicles with in‐wheel motor in traffic flow

IET Intelligent Transport Systems, Volume 15, Issue 6, Page 765-780, June 2021., 2021
Abstract Since electric vehicle with in‐wheel motor has advantages in aspects of vehicle dynamics control and energy‐efficient control, it has been widely applied in the vehicle platoon in the highway. This paper proposes an optimization and control structure that integrates ecological cooperative adaptive cruise control (CACC) for the vehicle platoon,
