The demand for energy has continued to increase because of global economic development, which has led to rising fuel prices and continued pollution problems. China is currently the largest coal consumer and is also the largest emitter of coal-fired CO emissions. However, past efficiency studies have been mostly limited to static analyses and have not considered undesirable outputs. Therefore, this study developed a bound dynamic directional distance function (DDF) data envelopment analysis (DEA) model to explore the energy and environmental efficiencies in 30 Chinese provinces from 2011 to 2015, from which it was found that (1) the overall efficiency was the best in the eastern region, but relatively low in the western region; (2) Beijing, Guangdong, Jiangsu, Shandong, Shanghai, Tianjin, Jiangxi, Jilin, and some other regions had efficiencies of 1; (3) the revenue and non-coal indicator efficiencies were reasonably good, but the expenditure and emissions efficiencies were generally poor; and (4) the key direction for primary improvements was found to be the emissions index.

All organisms are exposed to various stressors, which can sometimes lead to organismal death, depending on their intensity. While stress-induced organismal death has been observed in many species, the underlying mechanisms remain unclear. In this study, we investigated the molecular mechanisms of stress-induced organismal death in the fruit fly .

We study how protein condensates respond to a site of active RNA transcription (i.e., a gene promoter) due to electrostatic protein-RNA interactions.

The growing consumer interest in functional and health-oriented foods prompted the incorporation of tartary buckwheat sprout flour (TBSF) into food production. The addition of TBSF enhanced the nutritional value of noodles. Research has shown that as the proportion of TBSF increased, both the water absorption rate and thermal stability of the dough improved, while formation time decreased and dough aging was inhibited.

Recently, the atmospheric aerosol surface, which is reported to be quite acidic, is recognized as an important microreactive medium for atmospheric chemistry, profoundly impacting air quality and global climate. Nevertheless, the molecular-level understanding of the effect of surface-bound acids on atmospheric chemical reactions remains limited. Herein, the reactions between CO and NH/amines at the air-water interface with organic acids are investigated using combined molecular dynamic simulations and quantum chemical calculations.

Targeting thrombin to screen safe thrombin inhibitors from natural plants and animals is a critical direction in anticoagulant drug development. This study aimed to screen thrombin inhibitors from the nonbloodsucking leech Whitmania pigra (WP) and elucidate the mechanism of anticoagulation through a "computation-guided experimentation" strategy. A peptide library was constructed from WP hydrolysates, and virtual screening was performed using molecular docking and dynamics simulations.
