Note on Thermalization of Non-resonantly Produced Sterile Neutrinos [PDF]
JCAP 10 (2020) A01, 2020 Using an analytic treatment, we discuss the parameter regions of large active-sterile neutrino mixing angles where sterile neutrinos produced in non-resonant flavour oscillations can approach thermalization in several cosmologies. We show that thermalization affects only large active-sterile neutrino mixing already rejected by different limits.

Journal of Laboratory Medicine, 2021 – FSH is an influencing factor on parameters of bone metabolism.– Short term rFSH/HMG-treatment does not significantly enhance parameters of bone resorption.– No significant difference between rFSH- und HMG-stimulation has been found.

THBD sequence variants potentially related to recurrent pregnancy loss
Reproductive Biology and Endocrinology, 2017 Recurrent pregnancy loss (RPL) is a frequently occurring disease, which is classified as idiopathic in more than 50% of cases. THBD, the endothelial cell receptor for thrombin, has been associated with distinct biological processes and considered a ...

On the minimal active-sterile neutrino mixing in seesaw type I mechanism with sterile neutrinos at GeV scale [PDF]
Phys. Rev. D 89, 017302 (2014), 2013 Renewed interest in GeV-scale sterile neutrinos capable of explaining active neutrino oscillations via see-saw type I mechanism has been expressed in several proposals of direct searches. Given this activity we estimate the minimal values of sterile-active mixing angles provided one, two, or three sterile neutrinos are lighter than D-meson.

Sterile neutrino production at small mixing in the early universe [PDF]
, 2022 Sterile neutrinos can be produced in the early universe via interactions with their active counterparts. For small active-sterile mixing angles, thermal equilibrium with the standard model plasma is not reached and sterile neutrinos are only produced via flavor oscillations.

Male and female sterility in Zambia
Demographic Research, 2014 Background: Population measures of sterility are traditionally constructed for women, despite fertility and sterility being conditions of the couple. Estimates of male sterility provide insight into population-level sterility, and complement estimates ...
