Molecular structures in biopolymers sols and gels
The short range molecular structure of ogarose in the sol state and r-carrageenans in the gel state have been investigated by small-angle neutron scattering (0.1< q(nm'l) < 2.5). Agarose in the sol state possesses a rod-like conformation (minimum persistence length of 14 nm) with a mass per unit length consistent with a single helm The existence of a double helix in the gel state is accordingly...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Analysis of Mechanics and Dynamics of Biopolymers in Living Cells
F-actin polymers in the cytoskeleton provide mechanical strength and deformability to cells. Thus, understanding their dynamic responses to intracellular and extracellular cues is of critical importance for studying the biological and mechanical behaviors of cells. Unfortunately, to date, no computer software can provide researchers with adequate means to measure these responses since in vivo F...

متن کاملRandom Structures and Evolution of Biopolymers A computational case study on RNA secondary structures
We compute large ensembles of RNA secondary structures by means of various computer algorithms. Their secondary structures are sorted and ranked. The number of neutral neighbours (i.e. one error mutants of a sequence that have the same structure with that sequence) are computed as well as the length of neutral paths (i.e. adjacent neutral neighbours). We calculate and compare correlation length...
