As the largest producing country of municipal solid waste (MSW) around the world, China is always challenged by a lower utilization rate of MSW due to a lack of a smart MSW forecasting strategy.This paper mainly aims to construct an effective MSW prediction model to handle this problem by using machine learning techniques.Based Electronics on the e

Chronic stress is associated with the development of cardiovascular diseases.The sympathoneural system plays an important role in the regulation of cardiac function both in health and disease.In the present study, the changes in gene expression of the catecholamine biosynthetic enzymes tyrosine hydroxylase (TH), dopamine-β-hydroxylase (DBH) an
