Hadronic gamma-ray images of Sedov supernova remnants
, 2011 A number of modern experiments in high-energy astrophysics produce images of supernova remnants (SNRs) in the TeV and GeV gamma-rays. Either relativistic electrons (due to the inverse-Compton scattering) or protons (due to the pion decays) may be ...

physica status solidi (RRL) – Rapid Research Letters, EarlyView.A new parameterization of Si and Ge in the framework of the extended Hückel theory is presented. Bandgap and effective mass are calculated for unstrained and biaxially strained SiGe alloys. In SiGeC alloys with C atoms in close proximity, additional bands are observed, which are related to defect states in real crystals.

2+1-dimensional electrically charged black holes in Einstein - Power Maxwell Theory
, 2012 A large family of new black hole solutions in 2+1-dimensional Einstein-Power-Maxwell (EPM) gravity with prescribed physical properties is derived. We show with particular examples that according to the power parameter k of the Maxwell field, the obtained

SmartBot, EarlyView.Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...

SmartBot, EarlyView.Magnetic robots have the characteristics of small size, non‐cable drive and motion agility, but multi‐angle folding and real‐time reconfigurable magnetization are difficult to be integrated into small‐sized soft structures. Here, the authors propose a magnetic soft sheet robot based on the dynamic magnetization characteristics of magnetorheological ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,
