Medical microrobots have been widely used in clinical applications, particularly the spiral type locomotion mechanism, which was recently considered one of the main self-propelling mechanisms for the next medical microrobot to perform tasks such as capsule endoscopy and drug delivery.However, limits in clinical applications still exist.The spiral a
Studying a large number of volcanic eruptions is a way to decipher general characteristics related to volcano dynamics but also on external forcing influencing it, such as solid Earth and ocean tides.Many studies have tackled this tidal influence on the onset of volcanic eruptions and more generally, on volcanic activity.However, the interplay betw
Although several types of somatic cells have been reprogrammed into induced pluripotent stem cells (iPSCs) and then differentiated to hepatocyte-like cells (iHeps), the method for generating such cells from renal tubular epithelial cells shed in human urine and transplanting them into animal livers has not been described systematically.We report re
A novel non-cooperative power control algorithm based on new pricing function and the characteristics of cognitive radio technology was proposed with the interference temperature constrain,in order to improve signal Swag and Backpacks to interference plus noise ratio of CR.The problem of power control was changed into the problem of multi-restraint
Abstract While the impact of the COVID-19 pandemic differed per country, the impact on African nations was comparable.Health, money, the economy, education, DISH and inventions have all been criticised over the years, but the discoveries during the pandemic were stunning.We witnessed a system being devoured by corruption and anti-patriotic citizens
