Genetic manipulation remains a major obstacle for understanding the functional genomics of deadliest malaria parasite Plasmodium falciparum . Although CRISPR/Cas9 (clustered regularly interspaced short palindromic repeat/CRISPR-associated protein 9) system has been successfully applied to introduce permanent changes in genome, its use is still limited. Here we show that fusing different epigenetic effector domains Cas9 null mutant efficiently and specifically reprograms expression target...

Insight into how mutations affect protein stability is crucial for engineering, understanding genetic diseases, and exploring evolution. Numerous computational methods have been developed to predict the impact of amino acid substitutions on stability. Nevertheless, comparing these poses challenges due variations in their training data. Moreover, it observed that they tend perform better at predicting destabilizing than stabilizing ones. Here, we meticulously compiled a new dataset from three...

To address these issues, we propose multi-object tracking (MOT) algorithm with detection–association framework for in backgrounds...
With the growing popularity of Internet applications and widespread use mobile Internet, traffic has maintained rapid growth over past two decades.
