Pulsating in unison at optical and X-ray energies: simultaneous high-time resolution observations of the transitional millisecond pulsar PSR J1023+0038

, 2019
PSR J1023+0038 is the first millisecond pulsar discovered to pulsate in the visible band; such a detection took place when the pulsar was surrounded by an accretion disk and also showed X-ray pulsations.

The Progenitor Dependence of the Preexplosion Neutrino Emission in Core-Collapse Supernovae [PDF]

, 2013
We perform spherically-symmetric general-relativistic simulations of core collapse and the postbounce preexplosion phase in 32 presupernova stellar models of solar metallicity with zero-age-main-sequence masses of 12 M_{sun} to 120 M_{sun}.

Statistical Estimation of Quantum Tomography Protocols Quality

, 2010
A novel operational method for estimating the efficiency of quantum state tomography protocols is suggested. It is based on a-priori estimation of the quality of an arbitrary protocol by means of universal asymptotic fidelity distribution and condition ...

Amorphous-amorphous transition and the two-step replica symmetry breaking phase

, 2007
The nature of polyamorphism and amorphous-to-amorphous transition is investigated by means of an exactly solvable model with quenched disorder, the spherical s+p multi-spin interaction model.

The Mott insulator phase of the one dimensional Bose-Hubbard model: a high order perturbative study [PDF]

, 2006
The one dimensional Bose-Hubbard model at a unit filling factor is studied by means of a very high order symbolic perturbative expansion. Analytical expressions are derived for the ground state quantities such as energy per site, variance of on-site ...

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

Wildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Board age and value diversity: Evidence from a collectivistic and paternalistic culture

Borsa Istanbul Review, 2021
The current study investigates whether board age diversity affects company financial performance and risk, and whether diverse work-related values held by directors of different ages are the underlying cause of any effects via a sample of listed ...
