Environmental and social factors associated with the spread of Covid-19:- A review study
مجله دانشگاه علوم پزشکی بیرجند, 2023 Environmental and social determinants play a key role in health safety, and this factor is significantly highlighted in a pandemic situation. In this review study, determinants of health were examined from social and environmental approaches n the ...

Nature of singularities in anisotropic string cosmology [PDF]
, 2002 We study nature of singularities in anisotropic string-inspired cosmological models in the presence of a Gauss-Bonnet term. We analyze two string gravity models-- dilaton-driven and modulus-driven cases-- in the Bianchi type-I background without an axion

The octagon as a determinant [PDF]
Journal of High Energy Physics, 2019 Abstract The computation of a certain class of four-point functions of heavily charged BPS operators boils down to the computation of a special form factor — the octagon. In this paper, which is an extended version of the short note [1], we derive a non-perturbative formula for the square of the octagon as the determinant of a semi-

Journal of Information and Technology, 2016 Cloud computing (CC) is an emerging form of IT outsourcing (ITO) that requires organizations to adjust their sourcing processes. Although ITO researchers have established an extensive knowledge base on the determinant factors that drive sourcing ...

On some properties of a generalized min matrix
AIMS Mathematics, 2023 In this paper, we investigate a min matrix and obtain its $ LU $-decomposition, determinant, permanent, inverse, and norm properties. In addition, we obtain a recurrence relation provided by the characteristic polynomial of this matrix.

Complex Langevin dynamics and zeroes of the fermion determinant [PDF]
, 2017 A bstractQCD at nonzero baryon chemical potential suffers from the sign problem, due to the complex quark determinant. Complex Langevin dynamics can provide a solution, provided certain conditions are met.

A comparative study of overlap and staggered fermions in the Schwinger model [PDF]
, 2004 We investigate the validity of the square rooting procedure of the staggered determinant in the context of the Schwinger model. We find some evidence that at fixed physical quark mass the square root of the staggered determinant becomes proportional to ...

Frontiers in Oncology, 2022 BackgroundBreast cancer (BC) screening can be performed in a screening program (BCSP) or in opportunistic screening. The existing reviews on the determinants of non-participation depend on self-reported data which may be biased.

Determinant-Gravity: Cosmological implications
, 2004 We analyze the action $\int d^4x \sqrt{\det||{\cal B} g_{\mu\nu}+ {\cal C} R_{\mu\nu}}||$ as a possible alternative or addition to the Einstein gravity. Choosing a particular form of ${\cal B}(R)= \sqrt {R}$ we can restore the Einstein gravity and, if $
