The interest in dynamic processes on networks is steadily rising recent years. In this paper, we consider the (α,β)-Threshold Network Dynamics ((α,β)-Dynamics), where α≤β, which only structural dynamics (edge of network) are allowed, guided by local threshold rules executed each node. particular, discrete round t, active pair nodes u and v, computes a value E(u,v) (the potential pair) as functi...

Sommerfeld effect concerns the non-linear jump phenomena induced due to the influence of the unbalance response on a non-ideal drive around the critical speed of the excited structure. In this work, we study the influence of external and internal dampings and gyroscopic forces on the Sommerfeld effect in rotationally symmetric planar dynamical systems. The rotational symmetry assumption allows ...

Experimental investigations on protein dynamics are usually carried out in solution; however, in most cases, the determination of protein structure is done by crystallography that relies on the diffraction properties of the protein arranged in a three-dimensional lattice. X-ray Absorption Spectroscopy (XAS) is an ideal tool to investigate the deep relationships between structure and dynamics, o...

Previous simulation studies have suggested that structural dynamics and protein motion play an important role in enzyme catalysis, but these results are difficult to verify experimentally. R. August Estabrook et al. have developed a predictive approach to guide the direct experimental testing of how enzyme dynamics impact catalysis. Their method highlights specific amino acid pairs likely to be...

Small- and wide-angle X-ray scattering (SWAXS) has evolved into a powerful tool to study biological macromolecules in solution. The interpretation of SWAXS curves requires their accurate predictions from structural models. Such predictions are complicated by scattering contributions from the hydration layer and by effects from thermal fluctuations. Here, we describe the new web server WAXSiS (W...
