We confirm Odijk’s scaling laws for (i) the average chain extension; (ii) the variance about the average extension; and (iii) the confinement free energy of a wormlike chain confined in a rectangular nanochannel smaller than its chain persistence length through pruned-enriched Rosenbluth method (PERM) simulations of asymptotically long, discrete wormlike chains. In the course of this analysis, ...

We demonstrate that the recently proposed pruned-enriched Rosenbluth method (PERM) (Grassberger, Phys. Rev. E 56:3682, 1997) leads to extremely efficient algorithms for the folding of simple model proteins. We test it on several models for lattice heteropolymers, and compare it to published Monte Carlo studies of the properties of particular sequences. In all cases our method is faster than the...

Structure-preserving discretization of the Rosenbluth–Fokker–Planck equation is still an open question especially for unlike-particle collision. In this paper, a mass-energy-conserving isotropic scheme introduced. The structure related to energy conservation skew-symmetry in mathematical sense, and action–reaction law physical sense. A thermal relaxation term obtained by using integration-by-pa...

A criterion for assessing the reliability of measurements Sachs form factor ratio using Rosenbluth technique is proposed and applied to an analysis three known experiments (Andivahis1994, Walker1994, Qattan2005) a recent experiment on CEBAF accelerator upgraded 12 GeV at JLab (arXiv:2103.01842 [nucl-ex]). Based results polarization measuring $\mu_p G_E/G_M$ in $\vec e p \to \vec p$ process, kin...

this field study was conducted on 60 women who working in related centers of universities of medical sciences in tehran. data gathering tool was maternal separation anxiety questionnaire that designated by hock & et al. (1982).  findings revealed that majority of the research units (71.7%), have high degree of maternal separation anxiety. mean degree of maternal separation anxiety was (21.22±3....

The magnetic drift and the electric potential play an important role in microtearing destabilization by increasing growth rate of this instability presence collisions, while electrostatic plasma micro-turbulence, zonal potentials can have a strong impact on turbulent saturation. A reduced model has been developed, showing that Rechester–Rosenbluth is good for prediction electron heat diffusivit...

â a model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. while the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the cpu time is decreased ess...

Detailed study of the nucleons is very important to understand the nucleus. Electron-Proton scattering is the best tool to probe the nucleus and hence deep into it. In the One-Photon exchange (Born) approximation, the structure of the nucleon characterized by electric and magnetic form factors, GE(Q ) and GM(Q ), which depend only on momentum transfer squared, Q. At Q=0, the proton form factors...
