Neurons rely on a unique organization of their cytoskeleton to build, maintain and transform extraordinarily intricate shapes. After decades research the neuronal cytoskeleton, it is exciting that novel assemblies are still discovered thanks progress in cellular imaging methods. Indeed, super-resolution microscopy has revealed axons lined with periodic scaffold actin rings, spaced every 190 nm ...

In this paper, the periodic, quasi periodic and chaotic responses of rotational machines with a hexagonal centrifugal governor are studied. The external disturbance is assumed as a sinusoid effect. By using the forth order Rung-Kutta numerical integration method, bifurcation diagram, largest Lyapunov exponent and Lyapunov dimension are calculated and presented to detect the critical controlling...

we prove that each normal automorphism of the $n$-periodic product of cyclic groups of odd order $rge1003$ is inner, whenever $r$ divides $n$.

Typically, many of the modern buildings have concrete walls constructed from cinder block walls, that have periodic nature in their relative dielectric constant. This periodic nature excites higher-order Floquet harmonic modes at microwave frequencies, which leads to the propagation of scattered waves along with non-specular directions. Periodic structures exhibit different behaviors when illum...
