Lack of controllability of the heat equation with memory [PDF]
, 2012 We consider a model for the heat equation with memory, which has infinite propagation speed, like the standard heat equation. We prove that, in spite of this, for every T > 0 there exist square integrable initial data which cannot be steered to hit zero ...

Heat input calculation for friction welding
Journal of Japan Institute of Light Metals, 2004 In friction welding, heat input is significant factor, which affects the quality of welded joints. It is difficult to calculate the heat input, because friction heating is complicated phenomenon. Therefore, there is no general calculation method in friction welding. As one of the parameter for calculation, friction torque is used. However, torque meter

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
