In this short note, we presented a new proof of a weak log-majorization inequality for normal matrices and obtained a singular value inequality related to positive semi-definite matrices. What's more, we also gave an example to show that some conditi

The polygon effect is a major factor affecting the dynamic characteristics of chain drive in oil saw chain system. It causes impact, noise and dithering of the saw chain and significantly affects the lifespan of oil saw. A simple analytical method is

In this study, we explored the effects of soy isoflavone extracts on the growth of estrogen-dependent human breast cancer (MCF-7) tumors implanted in ovariectomized athymic mice. The ovariectomized athymic mice were implanted with MCF-7 cells. They w
