Linear and Non Linear Effects on the Newtonian Gravitational Constant as deduced from the Torsion Balance [PDF]
The Newtonian gravitational constant has still 150 parts per million of uncertainty. This paper examines the linear and nonlinear equations governing the rotational dynamics of the torsion gravitational balance.

Critical Oscillation Constant for Difference Equations with Almost Periodic Coefficients
We investigate a type of the Sturm-Liouville difference equations with almost periodic coefficients. We prove that there exists a constant, which is the borderline between the oscillation and the nonoscillation of these equations.

The Oscillation of a Class of the Fractional-Order Delay Differential Equations
Several oscillation results are proposed including necessary and sufficient conditions for the oscillation of fractional-order delay differential equations with constant coefficients, the sufficient or necessary and sufficient conditions for the ...

The Landauer's formula conductance of the telescoped armchair nanotubes is calculated with the Hamiltonian defined by first-principles calculations (SIESTA code). Herein, partially extracting the inner tube from the outer tube is called 'telescoping'. It

We are concerned with oscillation of the first order neutral delay differential equation [x(t)−px(t−τ)]′+qx(t−σ)=0 with constant coefficients, and we obtain some necessary and sufficient conditions of oscillation for all the solutions in respective cases

A Survey on the Oscillation of Difference Equations with Constant Delays
In this survey, necessary and sufficient conditions for the oscillation of all solutions of delay difference equations with one or several constant arguments, in terms of the characteristic equation, are presented.
