Data on safety and immunogenicity of coronavirus disease 2019 (COVID‐19) vaccinations in hepatocellular carcinoma (HCC) patients are limited. In this multicenter prospective study, HCC patients received two doses of inactivated whole‐virion COVID‐19 vaccines. The safety and neutralizing antibody were monitored. Totally, 74 patients were enrolled from 10 centers in China, and 37 (50.0%), 25 (33.8%),...
The dispersion characteristics of the grounding electrode is an important characteristics of tower grounding network. The electromagnetic parameters of the material have a great influence on the dispersion characteristics of the material with power frequency and impulse sources. In this paper, several kinds of metal and non-metallic grounding materials are selected that are often used for power system...
For simultaneous localization and mapping(SLAM) of underwater robots, the extended Kalman filter algorithm has the problems of slow convergence rate, low accuracy and poor numerical stability, and square root cubature Kalman filter SLAM algorithm (SRCKF-SLAM) for mobile robots is designed according to cubature Kalman filter (CKF) principle. The cubature rule is utilized to calculate Gaussian weighted...
High power pulsed power supply is the basis of electromagnetic emission. In this paper, the capacitor voltage limit mode and non-linear resistor voltage limit mode power pulsed power supply are common models. In this paper, two circuit modes based on high temperature superconducting (HTS) pulsed transformers were introduced and the working principle were analyzed respectively. In accordance with the...
The aim of this study is to assess the diagnostic value of interferon-γ release assays (IGRAs) for latent tuberculosis infection (LTBI) in patients with rheumatic disease before receiving biologic agents. MEDLINE and EMBASE databases were used for searching studies concerning the evaluation on the performance of IGRAs [QuantiFERON-TB Gold (QFT-G), QuantiFERON-TB Gold In-Tube (QFT-GIT) and T-SPOT.TB]...
