An improved model of t cell development in the thymus and its stability analysis

open access: yesMathematical Biosciences and Engineering, 2005
Based on some important experimental dates, in this paper weshall introduce time delays into Mehrs's non-linear differential system modelwhich is used to describe proliferation, differentiation and death of T cells inthe thymus (see, for example, [3], [6]

Gravitational fields with a non Abelian bidimensional Lie algebra of symmetries [PDF]

open access: yes, 2001
Vacuum gravitational fields invariant for a bidimensional non Abelian Lie algebra of Killing fields, are explicitly described. They are parameterized either by solutions of a transcendental equation (the tortoise equation) or by solutions of a linear ...

Pentagon integrals to arbitrary order in the dimensional regulator

open access: yesJournal of High Energy Physics, 2021
We analytically calculate one-loop five-point Master Integrals, pentagon integrals, with up to one off-shell leg to arbitrary order in the dimensional regulator in d = 4−2𝜖 space-time dimensions.

A new principle technic for the transformation from frequency domain to time domain

open access: yesAIP Advances, 2017
A principle technic for the transformation from frequency domain to time domain is presented. Firstly, a special type of frequency domain transcendental equation is obtained for an expected frequency domain parameter which is a rational or irrational ...
