In order 2-Layer Acrylic Keychain to improve the mechanical properties of the metal matrix composite, the copper-graphene composites were prepared by FSP (friction stir processing) method.The samples were analyzed through the metal microstructure observation test and mechanical test, the effects of agitation speed and the amount of graphite on the
Continual model learning for nonlinear dynamic systems, such as autonomous robots, presents several challenges.First, it tends to be computationally expensive as the amount of data collected by the robot quickly grows in time.Second, the model accuracy is impaired when data from repetitive motions prevail in the training set and outweigh scarcer sa
Traditional theories on ancient Egyptian mummification postulate that in the prehistoric period (i.e.the Neolithic and Chalcolithic periods, 5th and 4th millennia B.C.) bodies were naturally desiccated through the action of the hot, dry desert sand.Although molding of the body with resin-impregnated linen is believed to be an early Pharaonic foreru
Pluripotent stem cells represent one promising source for cell replacement therapy in heart, but differentiating embryonic stem cell-derived cardiomyocytes (ESC-CMs) are highly heterogeneous and show a variety of maturation states.In this study, we employed an ESC clonal line that contains a cardiac-restricted ncx1 promoter-driven puromycin resista
