A contact map is a simple representation of the structure of proteins and other chainlike macromolecules. This representation is quite amenable to numerical studies of folding. We show that the number of contact maps corresponding to the possible configurations of a polypeptide chain of N amino acids, represented by (N21)-step self-avoiding walks on a… (More)

We have carried out extensive computer simulations of one-dimensional models related to the low noise (solid-on-solid) non-equilibrium interface of a two dimensional anchored Toom model with unbiased and biased noise. For the unbiased case the computed uctuations of the interface in this limit provide new numerical evidence for the logarithmic correction to… (More)

We investigate the phase diagram and the segregation kinetics of a system of particles with three-body interactions on a two-dimensional square lattice. We compare this with the usual case of pair interactions which have particle–hole symmetry. Our simulations suggest that the kinetics belong to the same universality class as the symmetric model with pair… (More)

Astaxanthin (ASTX) is a keto carotenoid, which possesses a non-polar linear central conjugated chain and polar β-ionone rings with ketone and hydroxyl groups at the extreme ends. It is well known as a super anti-oxidant, and recent clinical studies have established its nutritional benefits. Although it occurs in several forms, including free molecule,… (More)
