Perturbation of eigenvalues of matrix pencils and optimal assignment problem [PDF]

open access: yes, 2004
We consider a matrix pencil whose coefficients depend on a positive parameter $\epsilon$, and have asymptotic equivalents of the form $a\epsilon^A$ when $\epsilon$ goes to zero, where the leading coefficient $a$ is complex, and the leading exponent $A ...

Third virial coefficient of the unitary Bose gas [PDF]

open access: yes, 2013
By unitary Bose gas we mean a system composed of spinless bosons with s-wave interaction of infinite scattering length and almost negligible (real or effective) range. Experiments are currently trying to realize it with cold atoms.

In silico evaluation of the antioxidant activity of 4-mercaptoimidazole monosubstituted derivatives

open access: yesTạp chí Khoa học và Công nghệ, 2023
In this study, 54 monoderivatives of 4-mercaptoimidazole (4MC) were screened for their antioxidant activity using computational simulations. It was discovered that the presence of electron-absorbing groups, such as NO2, CN, CF3, COOH, and COOCH3 ...

Asymptotic direction for random walks in random environments [PDF]

open access: yes, 2007
In this paper we study the property of asymptotic direction for random walks in random i.i.d. environments (RWRE). We prove that if the set of directions where the walk is transient is non empty and open, the walk admits an asymptotic direction. The main

Geodesically Complete Lorentzian Metrics on Some Homogeneous 3 Manifolds [PDF]

open access: yes, 2008
In this work it is shown that a necessary condition for the completeness of the geodesics of left invariant pseudo-Riemannian metrics on Lie groups is also sufficient in the case of 3-dimensional unimodular Lie groups, and not sufficient for 3 ...
