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.

Cadernos de Saúde Pública, 2009 A case-control study was carried out at a public teaching hospital in Recife, Pernambuco State, Brazil in 1997 to investigate risk factors among women who feel regret after undergoing sterilization through tubal ligation.

'Majorana mass' fermions as untrue Majorana particles, rather endowed with pseudoscalar-type charges than genuinely neutral [PDF]
, 2014 The idea of a `Majorana mass' to make a chiral neutrino really neutral is here reconsidered. It is pointed out that such an approach, unlike Majorana's (non-chiral) old one, does not strictly lead, in general, to a true self-conjugate particle. This can be seen on directly using the basic definition (or fundamental representation) of charge conjugation

Semileptonic decays of charmed and beauty baryons with sterile neutrinos in the final state [PDF]
Phys.Rev.D79:077701,2009, 2008 We obtain tree-level estimates of various differential branching ratios of heavy baryon decays with massive sterile neutrinos $\nu_{x}$ in the final state. Heavy sterile neutrinos can be searched for in heavy baryon decays with missing mass as a signature as well as in fixed target experiments, where heavy baryon decays contribute to sterile neutrino ...

Fallopian tube anatomy predicts pregnancy and pregnancy outcomes after tubal reversal surgery [PDF]
, 2019 We conducted this study to determine whether fallopian tube anatomy can predict the likelihood of pregnancy and pregnancy outcomes after tubal sterilization reversal. We built a flexible, non-parametric, multivariate model via generalized additive models to assess the effects of the following tubal parameters observed during tubal reparative surgery ...

About contamination by sterile females and residual male fertility on the effectiveness of the sterile insect technique. Impact on disease vector control and disease control [PDF]
arXiv, 2023 The sterile insect technique (SIT) is a technique to control pests and vectors of diseases by releasing mainly sterile males. Several challenges need to be solved before large-scale field application in order to guarantee its success. In this paper we intend to focus on two important issues: residual (sterile) male fertility and contamination by ...

Constraints on massive sterile neutrino species from current and future cosmological data [PDF]
Phys.Rev.D83:115023,2011, 2011 Sterile massive neutrinos are a natural extension of the Standard Model of elementary particles. The energy density of the extra sterile massive states affects cosmological measurements in an analogous way to that of active neutrino species. We perform here an analysis of current cosmological data and derive bounds on the masses of the active and the ...

Molecular Oncology, EarlyView.This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.
