Mainly addressed in this paper is the stability problem of continuous-time switched cascade nonlinear systems with time-varying delays.A robust convergence property is proved first: If a nominal switched nonlinear system with delays is asymptotically stable, then trajectories of corresponding perturbed system asymptotically approach origin provided
Abstract Background Non-vascularized bone grafting (NVBG) has demonstrated to treat osteonecrosis of the femoral head (ONFH).There are a number of articles updating the use of NVBG to treat the ONFH, but the percentage of patients subsequently undergoing a total hip arthroplasty (THA) is controversial.Methods Several electronic databases, including
This study explores highly eco-efficient preplaced aggregate concrete mixtures having superior tensile characteristics and impact resistance developed for pavement and infrastructure applications.A fully recycled granular skeleton consisting of recycled concrete aggregate and recycled tire rubber granules, and steel wire fibers from scrap tires are
quickderm for dogs The privilege walk (PW) has gained traction as a method to raise awareness of privilege and vulnerability across various settings.This experiential activity involves participants responding to statements about their identities and backgrounds by stepping forward or backward, illustrating disparities in social advantage.The PW can
Depression is the most common mental health problem affecting adolescents globally, wherein its increasing prevalence together with the negative health impacts escalates the need for further research in this area.This work determined the prevalence and factors associated with depressive symptoms among young adolescents in Malaysia.A total of 1350 a
