Arcuate nucleus-specific progesterone receptor knockdown in female mice is sufficient to induce PCOS-like hyperactivity in the reproductive axis. [PDF]
J NeuroendocrinolAbstract Mammalian reproductive function is dependent upon gonadal steroid hormone feedback within the hypothalamic–pituitary–gonadal (HPG) axis. In polycystic ovary syndrome (PCOS), impaired progesterone (P4) negative feedback leads to hyperactive pulsatile secretion of luteinising hormone (LH) and impaired reproductive function.

I–V and C–V characteristics and interface electron states of Al2O3/AlGaN/GaN structures [PDF]
Modern Electronic MaterialsThis paper analyzes properties of the dielectric/AlGaN/GaN system with an ALD Al2O3 film as a dielectric. It was investigated how the current flow process in the system changes due to the deposition of films with different thicknesses; at what bias ...

CONNECTION OF ADDITIONAL PULSAR EMISSION COMPONENTS IN THE CRAB WITH THE RESONANCE REFLECTION FROM A NEUTRON STAR [PDF]
Radio Physics and Radio Astronomy, 2018 Purpose: The subject of the paper is discussion of reflected radiation from the neutron star surface. Such radiation, as was shown earlier by S. V. Trofymenko and one of the authors, occurs when reflects the radiation of relativistic positrons flying ...

Why the distance of PSR J0218+4232 does not challenge pulsar emission theories [PDF]
, 2014 Recent VLBI measurements of the astrometric parameters of the millisecond pulsar J0218+4232 by Du et al. have suggested this pulsar is as distant as 6.3 kpc.

Pulsar statistics - IV. Pulsar velocities [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 We have used Monte Carlo simulations of the Galactic pulsar population to reassess the kinematics of radio pulsars in light of the large number of recently published proper motions and the revised distance model. Our modelling of the observational selection effects that distort the observed sample is far more detailed and self-consistent than that of ...

DETERMINATION OF THE ROTATION MEASURE VALUE SIGN WHEN RECEIVING A SINGLE LINEAR POLARIZATION OF THE PULSAR RADIO EMISSION [PDF]
Radio Physics and Radio Astronomy, 2020 Purpose: The studies of pulsars allow enriching our knowledge in determination of parameters of both the exotic electron-positron plasma in the pulsar magnetosphere with strong magnetic field and the ordinary ion-electron plasma of the interstellar ...

Physics Today, 1968 THE DISCOVERY OF PULSARS, or rapidly pulsating radio sources, was, like certain other historic events in astronomy, an accident. It is reminiscent of the unexpected detection of radio bursts from Jupiter by Bernard F. Burke and Kenneth L. Franklin, who were studying the Crab Nebula, and of the discovery of the cosmic fireball radiation by Arno A ...
