In this paper we give a necessary and sufficient condition for the oscillation of the first-order neutral differential equations of Euler form with variable unbounded delays $\tfrac{d} {{dt}}\left( {x ...

This paper is concerned with the relationship between the concepts of oscillation, nonoscillation and disconjugacy of the general third order linear differential equation y''' + p(x)y" + q(x)y' + ...

From cadence to stride length and heart rate to calories burned, there’s an abundance of measurements and markers most smart watches can track these days. One metric you may have noticed even if you ...
