We propose a novel mechanism to generate sterile neutrinos $\nu_s$ in the early Universe, by converting ordinary $\nu_\alpha$ scattering processes $\nu_s\nu_\alpha\to\nu_s\nu_s$. After initial production oscillations, this leads an exponential growth abundance. show that such regime naturally occurs for self-interacting $\nu_s$, and opens up significant new parameter space where make all of obs...

The delivery of sterile products to the sterile field is essential to perioperative practice. The use of protective packaging for sterilized items is crucial to helping ensure that patients receive sterile items for surgical procedures. AORN's "Recommended practices for selection and use of packaging systems for sterilization" offers guidance to perioperative team members in evaluating, selecti...

New predictions for the antineutrino flux from nuclear reactors suggest that reactor experiments may have measured a deficit in this flux, which can be interpreted in terms of oscillations between the known active neutrinos and new sterile states. We perform a reanalysis of global short-baseline neutrino oscillation data in a framework with one or two sterile neutrinos. While one sterile neutri...

Cosmological and astrophysical constraints on the mixings of sterile neutrinos are commonly much more stringent than the ones coming from laboratory searches. Within the standard cosmological picture, this mixing needs to be very small to prevent the cosmological overabundance of sterile neutrinos. We present here a scenario, based on a low reheating temperature TRH ≪ 100 MeV at the end of (the...

The idealized individual in many fungal species is a haploid self-sterile hermaphrodite that may be propagated by asexually produced spores or that may reproduce sexually. In field populations, polymorphism occurs for female-sterile/hermaphrodite status, and female-sterile mutants, which function only as males during sexual reproduction, may comprise > 50% of the population. The effective popul...
