Asymptotics of Linear Waves and Resonances with Applications to Black Holes [PDF]
, 2015 We describe asymptotic behavior of linear waves on Kerr(–de Sitter) black holes and more general Lorentzian manifolds, providing a quantitative analysis of the ringdown phenomenon.

Journal of Reproductive Immunology, 2022 The authors state that sperm apoptosis is a useful indicator of male infertility in the case of varicocele, while being unable to detect Fas and Fas-L on sperm cells. At the same time, they also claim that the presence of Fas is a debated issue. We demonstrated beyond any reasonable doubt that Fas is not present in human sperm and clarified that ...

Quality of Semen Stored in On-the-Farm Semen Tanks
Journal of Dairy Science, 1980 We assessed the damage to frozen semen packaged in French straws stored for 2 yr in 60 on-the-farm semen tanks on 56 Washington dairy farms. Percentage of motile spermatozoa and percentage of spermatozoa with intact acrosomes were not affected significantly by position of the semen on the rack (top or bottom goblet).

Birthweight and semen characteristics [PDF]
International Journal of Andrology, 2000 A correlation between birthweight and sperm counts in adult life was anticipated because impaired fetal growth could impair replication of Sertoli cells produced in fetal life. Furthermore, it was expected that males born with a high birthweight might have impaired sperm production as they are expected to have been exposed to higher levels of oestrogen

Symmetry-breaking phase-transitions in highly concentrated semen [PDF]
, 2016 New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shaped micro- fluidic chip leads to a spontaneous vortex state of the fluid at sufficiently large sperm concentration.
