Global prevalence of strains with recombinant genes (Rec-Mas) horizontally transferred from : two major types, dominant circulating clone 7 and MLST ST46 sequence type.

Unlabelled: is a group of emerging antimicrobial-resistant nontuberculous mycobacteria that causes severe lung disease in infected patients globally. Recently, molecular epidemiology studies have indicated that horizontal gene transfer (HGT) events in the gene are prevalent between subspecies. To determine the global prevalence of strains subjected to HGT, we performed phylogenetic inference using a 711-bp sequence extracted from 1,786 .

Triggering Reversible Intercalation-Conversion Combined Chemistry for High-Energy-Density Lithium Battery Cathodes.

Combining intercalation and conversion reactions maximizes the utilization of redox-active elements in electrodes, providing a means for overcoming the current capacity ceiling. However, integrating both mechanisms within a single electrode material presents significant challenges owing to their contrasting structural requirements. Intercalation requires a well-defined host structure for efficient lithium-ion diffusion, whereas conversion reactions entail structural reorganization, which can undermine intercalation capabilities.
