Protein binding can induce DNA kinks, which are for example important to enhance the specificity of the interaction and to facilitate the assembly of multi protein complexes. The respective proteins frequently exhibit amino acid sidechains that intercalate between the DNA base steps at the site of the kink. However, on a molecular level there is only little information available about the role ...

Context. It is known that hydrodynamic triangular jets (i.e. the jet with maximal velocity at its axis, which linearly decreases both sides) are unstable to anti-symmetric kink perturbations. The inclusion of magnetic field may lead stabilisation jets. Jets and complex fields ubiquitous in solar atmosphere, suggests possibility instability certain cases. Aims. aim paper study sandwiched between...

The gravitational instability of kinks is scrutinized in the context information entropy, including black hole formation near scalar field critical collapse. differential configurational entropy (DCE) computed and examined for globally perturbed static far-from-equilibrium kink solutions as well. In case first kink, DCE determines a value perturbation parameter regulating points bifurcation tha...

Elucidation of homoepitaxial growth mechanisms on vicinal non-polar surfaces of GaN is highly important for gaining an understanding of and control thin film surface morphology and properties. Using first-principles calculations, we study the step-flow growth in m-plane GaN based on atomic row nucleation and kink propagation kinetics. Ga-N dimer adsorption onto the m-plane is energetically more...

The present paper deals with results of orbital instability of periodic waves related to sine-Gordon equation. Our periodic solutions obtained in our study tend to a kink wave solutions in the infinite wavelength scenario. The approaches used here will be the classical Grillakis, Shatah and Strauss’ theory.

In the present work we explore competition of quadratic and quartic dispersion in producing kink-like solitary waves a model nonlinear Schrödinger type bearing cubic nonlinearity. We first 6 families multikink solutions their bifurcations as strength is varied. reveal rich bifurcation structure for system, connecting two-kink states with involving 4-, well 6-kinks. The stability all these explo...
