Traditional flexure hinges are designed by using a single material, and their performance is inadequate, compared to the ideal hinge.This paper presents a topology-optimization design method for multi-material flexure hinges based on the tamiya xf-16 element stacking method.A topology optimization model for multi-material flexure hinges is construc

Cell entry of severe acute respiratory coronavirus-2 (SARS-CoV-2) and other CoVs can occur via two distinct routes.Following receptor binding by the spike glycoprotein, membrane fusion can be triggered by spike cleavage either at the cell surface in a transmembrane serine protease 2 (TMPRSS2)-dependent tamiya xf-16 manner or within endosomes in a c

ABSTRACT BACKGROUND AND OBJECTIVES: Victims of traumatic brain injury, in intensive care units, frequently experience pain.Tracheal aspiration is a procedure with nociceptive potential routinely carried out in these patients.The objective of this study was to evaluate the effectiveness of tracheal aspiration in patients with traumatic brain injury

mama mellace s mores Impulsive differential systems are an important class of mathematical models for many practical systems in physics, chemistry, biology, engineering, and information science that exhibit impulsive dynamical behaviors due to abrupt changes at certain instants during the dynamical processes.This paper studies the controllability a
