Bending and Twisting Elasticity of DNA
We derive the elastic theory suitable for describing the free energy required to deform a stiff helical molecule with the symmetry of DNA. At quadratic levels in the strains we find, in addition to the independent bending and torsional energies incorporated in previous theories, a previously unknown coupling between twist and bend. If the backbone is given constant curvature, minimization of th...

The main goal of the paper is to present how CAD and the simulation results of a virtual model were used to develop and adapt an educational platform to various manufacturing scenarios in an Industrial Logistics laboratory optimizing the performances in terms of productivity. Our paper is divided in two parts. The first part describes the design and development of an educational platform contai...

The paper is concerned about the system of automatic detecting of wear and damages of the end mill tool by the use of computer vision. By using the algorithms developed for image segmentation and by an innovative approach to extraction of features describing individual end mill tool tooth the information representing significant features of the individual tool tooth is effectively gained from t...
متن کاملTwisting and bending stress in DNA minicircles.
The interplay between bending of the molecule axis and appearance of disruptions in circular DNA molecules, with ∼100 base pairs, is addressed. Three minicircles with different radii and almost equal contents of AT and GC pairs are investigated. The DNA sequences are modeled by a mesoscopic Hamiltonian which describes the essential interactions in the helix at the level of the base pair and inc...
متن کاملBending and Twisting Elasticity: a Revised Marko-Siggia Model on DNA Chirality
A revised Marko-Siggia elastic model for DNA double helix [Macromolecules 27, 981 (1994)] is proposed, which includes the WLC bending energy and a new chiral twisting energy term. It is predicted that the mean helical repeat length (HRL) for short DNA rings increases with the decreasing of chain length; while for very long chains, their mean HRL is the same, independent of both the chain length...
