The spread of atmospheric pollutants in the Sichuan Basin is difficult because of its unique topography, static wind, high humidity, and other meteorological conditions. Owing to the acceleration of urbanization and industrialization, PM pollution in the region is becoming increasingly severe, and the Sichuan Basin has become one of the key areas of national air pollution prevention and control. In this study, based on the remote sensing inversion product of PM concentration, spatial autocorrelation and gray correlation analyses are used to evaluate the spatial and temporal distribution characteristics and influencing factors of PM concentration in the Sichuan Basin.

It is important to understand the response of vegetation to climate change in Tibetan Pla-teau (TP), an ecological barrier for China and Asia. The spatiotemporal variation of the normalized difference vegetation index (NDVI) of vegetation growing season were analyzed based on the gro-wing season NDVI retrieved from MOD09A1. The relationship between NDVI and climate factors was analyzed by combining the data of meteorological stations in TP from 2001 to 2018.

Magnetic hyperthermia (MH) mediated by magnetic nanoparticles is one of the most promising antitumor modalities. The past several decades have witnessed great progress for MH antitumor therapy in scientific trials and clinic applications since it was initially advanced by Gilchrist et al. The ultimate object of MH in vivo is to efficiently kill cancer cells, and hence, it is of great importance to develop an optimized cellular MH method to evaluate the therapeutic efficiency in vitro.
