Stretching an anisotropic DNA.

چکیده
We present a perturbation theory to find the response of an anisotropic DNA to the external tension. It is shown that the anisotropy has a nonzero but small contribution to the force-extension curve of the DNA. Thus an anisotropic DNA behaves like an isotropic one with an effective bending constant equal to the harmonic average of its soft and hard bending constants.

Tight- binding study of electronic band structure of anisotropic honeycomb lattice
The two-dimensional structure of graphene, consisting of an isotropic hexagonal lattice of carbon atoms, shows fascinating electronic properties, such as a gapless energy band and Dirac fermion behavior of electrons at fermi surface. Anisotropy can be induced in this structure by electrochemical pressure. In this article, by using tight-binding method, we review anisotropy effects in the elect...
متن کاملNumerische Simulation Auf Massiv Parallelen Rechnern Anisotropic Mesh Construction and Error Estimation in the Nite Element Method Preprint-reihe Des Chemnitzer Sfb 393
In an anisotropic adaptive nite element algorithm one usually needs an error estimator that yields the error size but also the stretching directions and stretching ratios of the elements of a (quasi) optimal anisotropic mesh. However the last two ingredients can not be extracted from any of the known anisotropic a posteriori error estimators. Therefore a heuristic approach is pursued here, name...
متن کاملAdaptive finite elements with large aspect ratio based on an anisotropic error estimator involving first order derivatives
An anisotropic error estimator involving only first order derivatives is proposed for the Laplace problem and continuous, piecewise linear finite elements. Upper and lower bounds are presented, the involved constants being independent of the mesh aspect ratio provided the error gradient is equidistributed in the directions of maximum and minimum stretching. An anisotropic adaptive algorithm is ...
متن کاملVortex stretching and anisotropic diffusion in the 3D Navier-Stokes equations
The goal of this article is to present – in a cohesive, and somewhat self-contained fashion – several recent results revealing an experimentally, numerically, and mathematical analysis-supported geometric scenario manifesting large data logarithmic sub-criticality of the 3D Navier-Stokes regularity problem. Shortly – in this scenario – the transversal small scales produced by the mechanism of v...
متن کاملThe Alignment of Rods and Disks in Turbulence
We study the orientation and rotational dynamics of anisotropic particles in homogenous isotropic turbulence. By analyzing direct numerical simulation (DNS) data at Taylor-microscale Reynolds number of Rλ = 180, we quantify the preferential alignment between particle orientations and vorticity, as well as alignment with principal stretching directions defined by the Cauchy-Green strain tensor. ...
