ThO2 is a promising fuel for next-generation nuclear reactors.As a critical quantity measuring its radiation tolerance, the dependence of the threshold displacement energy on temperature and crystal orientation in ThO2 is unclear and established using comprehensive molecular dynamics simulations in this work.For both Th and O primary knock-on atoms
Abstract Background Protein-DNA interaction governs a large number of cellular processes, and it can be altered by a small fraction of interface residues, i.e., the so-called hot spots, which account for most of the interface binding free energy.Accurate prediction of hot spots is critical to understand the principle of protein-DNA interactions.The
To achieve mobility and rapid-response, vehicles are used to launch satellites, and such systems will inevitably undergo random vibrations caused by uneven ground excitations.However, cameras or other high-precision satellite payloads cannot withstand such harsh mechanical environment in the absence of isolators.Hence, in the Washing present paper,
Ellipse center extraction is the important basis of camera calibration with circle arrays calibration board, which directly affects the measurement accuracy of machine vision system.Aiming at the problem of high noise sensitivity of the most ellipse center extraction methods, a high robust multi-ellipse center extraction method is proposed.The idea
In various practical scenarios, autonomous vehicles must navigate through unfamiliar areas to reach their destinations.This navigation is facilitated by two-dimensional (2D) and three-dimensional (3D) maps.Simultaneous localization and mapping (SLAM) systems enable autonomous vehicles to map their surroundings while in motion.Traditionally, SLAM sy
