Star Product and Star Exponential [PDF]

open access: yes, 2012
This paper introduces a family of star products, parameterized by the space of complex symmetric matrices. Let us recall that Omori-Maeda-Miyazaki-Yoshioka obtained a generalization of the well-known Moyal-Weyl product by means of complex symmetric matrices.

A Magnetospheric Dichotomy for Pulsars with Extreme Inclinations

open access: yesUniverse, 2021
In this work, we expand on a comment by Lyne et al. (2017), that intermittent pulsars tend to congregate near a stripe in the logarithmic period versus period-derivative diagram.

The Evolutionary Statuses of Solar Type Detached Eclipsing Binary Stars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
We presented fundamental stellar parameters and evolutionary statuses of six solar type detached eclipsing binaries whose masses are in the range of 0.97-1.43 M⊙. EK Cep and FL Lyr belong to the zero age main sequence.

Rainbow’s stars [PDF]

open access: yesThe European Physical Journal C, 2017
In recent years, a growing interest on the equilibrium of compact astrophysical objects like white dwarf and neutron stars has been manifested. In particular, various modifications due to Planck scale energy effects have been considered. In this paper we analyze the modification induced by Gravity's Rainbow on the equilibrium configurations described ...

Safety and Efficacy of Anticoagulation Therapy in Paediatric Patients With Solid Tumours or Lymphomas at Risk of Thrombocytopenia: A Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Patients with solid tumours or lymphomas have an increased risk of thromboembolism (TE) and thrombocytopenia. Evidence‐based strategies for anticoagulation therapy (ACT) for patients with thrombocytopenia are limited. We examined the impact of thrombocytopenia on ACT administration and bleeding incidence in children with solid ...
