Based on Lyapunov exponent criterion, the aircraft lateral-directional stability during critical flight cases is presented.A periodic motion or limit cycle oscillation isdisplayed.A candidate mechanism for the wing rock limit cycle is the inertia coupling between an unstable lateral-directional (Dutch roll) mode with stable longitudinal (short peri
About 10% of male infertile patients show abnormalities in spermatogenesis.The microdeletion of azoospermia factor a (AZFa) region of the Y chromosome is thought to be a cause of spermatogenic failure.However, candidate gene responsible for the spermatogenic failure in AZFa deleted patients has not been elucidated yet.Using mice, we explored the RE
