Analysis of Rho GTPase signalling pathways regulating epithelial morphogenesis [PDF]

, 2010
Rho GTPases are molecular switches controlling many aspects of cell behaviour, including cell cycle progression, cell division, migration and morphology. The activity of Rho proteins is regulated by conformational changes induced by binding of guanine

Tight-binding molecular-dynamics study of liquid Si

, 1992
We have carried out molecular-dynamics simulation of liquid Si using the tight-binding Hamiltonian proposed by Goodwin, Skinner and Pettifor. The simulation results on the structural and dynamical properties (radial and angular distribution functions ...

Size effect in four-component Au-Cu-Pd-Pt nanoparticles and their stability

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов
The four-component Au-Cu-Pd-Pt nanosystems of different sizes with the stoichiometric composition Au3CuPd12Pt4 were studied. The molecular dynamics method was used as a simulation method, the interatomic interaction was described by the tight-binding ...

THE INTERFACE BOUNDARY ROLE DURING THE HEAT CAPACITY CALCULATIONS OF CU NANOCLASTERS SYNTHESIZED FROM GAS PHRASE [PDF]

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2013
Using molecular dynamics and modified tight-binding potential, the heat of Cu nanoclusters synthesized from the gas phase has been studied. It was shown that the interface boundary in agglomerated clusters cannot be the main reason of the significant ...

Indirect Interaction between Adatoms on a Tight-Binding Solid

, 1973
The indirect interaction between adatom pairs on the (100) surface of a simple-cubic tight-binding solid is investigated within a molecular-orbital approach. A general scheme for calculating the surface-density-of-states change and the interaction energy
