Electron beam irradiation on novel coronavirus (COVID-19): A Monte–Carlo simulation*

Autor: Wanzhao Cui, Guobao Feng, Lu Liu, Fang Wang

Publikováno v: Chinese Physics B = Zhongguo Wu Li B

The novel coronavirus pneumonia triggered by COVID-19 is now raging the whole world. As a rapid and reliable killing COVID-19 method in industry, electron beam irradiation can interact with virus molecules and destroy their activity. With the unexpec

New mechanism of solution of the k B T-problem in magnetobiology

Autor: Jürn W. P. Schmelzer, Zakirjon Kanokov, Avazbek Nasirov

Publikováno v: Open Physics, Vol 8, Iss 4, Pp 667-671 (2010)

The effect of ultralow-frequency or static magnetic and electric fields on biological processes is of huge interest for researchers due to the resonant change of the intensity of biochemical reactions although the energy in such fields is small. A si

Deformation in cooperative molecular motors

Autor: Sencer Taneri, M. Cemal Yalabik

Publikováno v: European Physical Journal B

We implement a model to represent the effect of the deformation of the backbone of a system of motor proteins while sliding on a track filament. This model incorporates a nearest neighbor interaction term among the motors for the deformation energy.

Energy transfer in nonlinear network models of proteins

We investigate how nonlinearity and topological disorder affect the energy relaxation of local kicks in coarse-grained network models of proteins. We find that nonlinearity promotes long-range, coherent transfer of substantial energy to specific, fun
