Variable stiffness actuator is a new actuation of robot which is inspired by motor control of human arm.And it is promising way to exploit the human-like performance and Underwear human-like motion.However, due to the mechanical complexity and redundancy of the actuators, it is not trivial to control the variable stiffness actuated robot to perform
Endometrial injury caused by intrauterine surgery often leads to pathophysiological changes in the intrauterine environment, resulting in infertility in women of childbearing age.However, clinical treatment strategies, especially for moderate to severe injuries, often fail to provide satisfactory therapeutic effects and pregnancy outcomes.With the
Introduction.It should be noted that the study on the problem Soaps of the effect of the mass of parts on the vibration-abrasive processing is insufficient.In the works of A.P.Babichev and M.A.Tamarkin, the fact of such an effect is mentioned, but the degree and mechanism of the effect are not disclosed.In the metal removal formulas, only the numbe
Cooperation is widespread across the tree of life, with examples ranging from vertebrates to lichens to multispecies biofilms.The initial evolution of such cooperation is likely to involve interactions that produce non-additive fitness effects among small groups of individuals in local populations.However, most models for the evolution of cooperati
