In att nighthawk hotspot this paper, we derive accurate outage probability and bit error rate expressions for a high altitude platform station (HAPS) assisted terrestrial communication system.In particular, HAPS is deployed as a relay node to assist two ground stations for data transmission.Each ground station-to-HAPS communication link works on a
Perinatal loss, especially in the advanced stages of pregnancy, is associated with severe psychological distress.Insufficient processing of the loss experience can result in a psychological disorder for some of those affected.This holds true especially for women who have suffered a pregnancy loss after the 20th week of pregnancy.Depressive disorder
To investigate the effect of fissure penetration on the spalling process and features of fleshlight automatique rectangular tunnel sidewalls, true triaxial compression tests were conducted on cubic sandstone specimens with varying fissure penetration degrees.Acoustic emission monitoring and video equipment were used to record the failure process of
High-temperature structural materials face severe degradation challenges due to oxidation and corrosion, leading to reduced long-term stability and performance.This review comprehensively examines the interfacial migration mechanisms of reactive elements (REs) such as Ti, Al, and Cr in 7gm pravana Ni/Fe-based alloys, emphasizing their role in formi
