In this paper, we introduce a general numerical method to approximate the reproduction numbers of a large class of multi-group, age-structured, population models with a finite age span.To provide complete flexibility in the definition of the birth and transition processes, we propose an Vacuum Brush Roller equivalent formulation for the age-integra
Abstract ATPase Inhibitory Factor 1 (IF1) regulates the activity of mitochondrial ATP synthase.The expression of IF1 in differentiated human and mouse cells is highly variable.In intestinal cells, the overexpression of IF1 protects against colon inflammation.Herein, we have developed a conditional IF1-knockout mouse model in intestinal epithelium t
Over the last few decades, the English language has become prevalent throughout the world in the domains of international diplomacy, business, research, and technology and is becoming increasingly important in many other areas.Much research into the use of English as a lingua franca has focused on its role in fostering communication across linguist
This paper presents a positioning error model and a control compensation scheme for a six-degree-of-freedom (6-DOF) micro-positioner based on a compliant mechanism and piezoelectric actuators (PZT).The positioning error model is established by means of the kinematic model of the compliant mechanism and complete differential coefficient theory, whic
