Collective oscillation period of inter-coupled biological negative cyclic feedback oscillators [PDF]

open access: yes, 2014
A number of biological rhythms originate from networks comprised of multiple cellular oscillators. But analytical results are still lacking on the collective oscillation period of inter-coupled gene regulatory oscillators, which, as has been reported ...

Oscillatory results for second-order noncanonical delay differential equations [PDF]

open access: yesOpuscula Mathematica, 2019
The main purpose of this paper is to improve recent oscillation results for the second-order half-linear delay differential equation \[\left(r(t)\left(y'(t)\right)^\gamma\right)'+q(t)y^\gamma(\tau(t))= 0, \quad t\geq t_0,\] under the condition \[\int_ ...

Aspects of Neutrino Oscillation in Alternative Gravity Theories

open access: yes, 2015
Neutrino spin and flavour oscillation in curved spacetime have been studied for the most general static spherically symmetric configuration. Using the symmetry properties we have derived spin oscillation frequency for neutrino moving along a geodesic or ...

Resonance in Bose-Einstein condensate oscillation from a periodic variation in scattering length [PDF]

open access: yes, 2003
Using the explicit numerical solution of the axially-symmetric Gross-Pitaevskii equation we study the oscillation of the Bose-Einstein condensate induced by a periodic variation in the atomic scattering length $a$. When the frequency of oscillation of $a$

Functional differential equations in the non-canonical case: New conditions for oscillation

open access: yesAIMS Mathematics
In this paper, we study the oscillation of a class of second-order nonlinear differential equations with mixed neutral terms in the non-canonical case. New criteria are derived that ensure the oscillation of the studied equation.

Oscillation theorems for certain third order nonlinear delay dynamic equations on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, we establish some new oscillation criteria for the third order nonlinear delay dynamic equations $$\left(b(t)\left([a(t)(x^\Delta(t))^{\alpha_1}]^\Delta\right)^{\alpha_2}\right)^\Delta+q(t)x^{\alpha_3}(\tau(t))=0$$ on a time scale $\mathbb{
