This paper addresses the design of a novel bionic robotic device for upper limb rehabilitation tasks at home.The main goal of the design process has been to obtain a rehabilitation device,which can be easily portable and can be managed remotely by a profe
Stingrays can undulate their wide pectoral fins to thrust themselves and swim freely underwater.Many researchers have used bionics to directly imitate their undulating mechanism and manufacture undulatory underwater robots.Based on the limitations of the
For magmatic rocks,it is often found that zircon 206 Pb/238 U and 207 Pb/235 U ratios continuously plot on the concordia line with a relatively large age span for the same sample,which gives rise to large dating errors or even unrealistic dating results.A
