Long Short‐Term Memory Network for Co‐Frequency Co‐Time Full‐Duplex Digital Domain Interference Suppression

IET Science, Measurement & Technology
The co‐frequency co‐time full duplex (CCFD) system transmits and receives signals at the same frequency simultaneously, which can effectively improve the communication spectrum utilization of satellite and solve the problem of satellite frequency ...

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Effect of vacuum and air heat treatments on the properties of the electroless Ni−P coating on magnesium alloy

Materials Research Express
Electroless Ni−P coatings on magnesium alloy specimens were heat-treated in vacuum and air atmospheres at 200 °C, 250 °C, and 300 °C. The results showed that the coating grains evolved into fine nodular structures following heat treatment at 200 °C and ...
