The nanosecond self-pulsing operation of a midinfrared solid-state Conditioner laser with no additional passive absorbers is reported in this paper.A proof-of-principle demonstration of the cooperatively enhanced reabsorption method, in which two laserdiode-pumped erbium gain media share the same laser resonator, is proposed.The two excited media a
ObjectivesStudies have Floor Sealer identified increased cancer risk among patients undergoing total hip arthroplasty (THA) compared to the general population.However, evidence of all-cause and site-specific cancer risk associated with different bearing surfaces has varied, with previous studies having short latency periods with respect to use of m
Potential earthquake-induced damage to overlapped tunnels probably occurs during the Leather Wallet operation and maintenance of mountain tunnel engineering, especially in the seismically active zone.This study investigated the dynamic response and the failure characteristics of the parallel overlapped tunnel under seismic loadings by employing sha
