Global navigation satellite system (GNSS) integer ambiguity acceptance test is one of the open problems in GNSS data processing.A number of ambiguity acceptance tests have been proposed from different perspectives and then unified into the integer aperture estimation framework.The existing comparative studies indicate that the impact of test statis
We previously demonstrated that cholesterol deprivation increases endothelial cyclooxygenase-2 (COX-2)-dependent prostacyclin [prostaglandin I2 (PGI2)] production in vitro.Cholesterol directly regulates gene transcription through the sterol response element binding protein (SREBP).In this work, we demonstrate that SREBP directly regulates COX-2 exp
The difficulty of students in learning chemistry subjects is due to the use of media that is not in accordance with the characteristics of students who want fun-based learning.Therefore, it is necessary to develop a Lego hydrocarbon learning media that is suitable for use as a learning medium for hydrocarbon materials.This study aims to produce a f
With the continuous development of network communication technology, the development of simulation training system based on the power of the Internet has been studied.Chemical enterprises themselves have high risks, so the issue of safe production is more and more serious.In this paper, a simulation training system suitable for chemical production
