The interaction of the Alzheimer's amyloid beta peptide, Aβ40, with sodium dodecyl sulfate (SDS) micelles, together with the self-assembly of SDS molecules around the peptide from an initial random distribution were studied using atomistic and coarse-grained (CG) molecular dynamics simulations. In atomistic simulations, the peptide structure in the micelle(More)
Mixtures of Trifluoroethanol (TFE) and water with different proportions are studied using molecular dynamics simulations. The radial and spatial distribution functions, as well as the size distribution of TFE clusters are obtained from the trajectories. The variation of radial and spatial distribution functions with composition show that the addition of TFE(More)
In this paper, we present a new way to simulate Turing machines using a specific form of Petri nets such that the resulting nets are capable of thoroughly describing behavior of the input Turing machines. We model every element of a Turing machine’s tuple F) q0, δ, Σ, b, Γ, Q, (i.e., with an equivalent translation in Colored Petri net’s set of elements with(More)
We report the results of the electronic structure calculation of a newly discovered member of the YBCO high-Tc family, i.e., Y3Ba5Cu8O18 (Y358) with Tc > 100, based on the full-potential linearized augmented plane waves method (FP-LAPW) of density functional theory in the generalized gradient approximation (GGA). The evolution of the number of hole carriers(More)
The amylin peptide in a dioleoylphosphatidylcholine (DOPC) bilayer is studied using united atom molecular dynamics (MD) simulations. Dynamics and transport properties of the peptide and the phospholipid bilayer are investigated. The lateral diffusion of DOPC is in the order of 10−8 cm2 s−1, which is in agreement with the experimental results. The order(More)
