✦ Synopsis

The present paper considers a biaxial nematogenic lattice model, involving particles of D 2h symmetry, whose centres of mass are associated with a three-dimensional simple-cubic lattice; the pair potential is isotropic in orientation space, restricted to nearest neighbours, and has the simpliÿed form recently proposed by Sonnet, et al. (Phys. Rev. E 67 (2003) 061701); the mean ÿeld analysis carried out by the named authors predicts a range of parameters where a direct ÿrst-order transition occurs between biaxial and isotropic phases; we have performed Monte Carlo simulations, and found results which qualitatively conÿrm their prediction.

By now, nematogenic lattice models have been extensively studied in the literature dealing with liquid crystals; they usually involve cylindrically symmetric (uniaxial) particles and pairwise additive interaction potentials. On the other hand, quantum mechanical perturbation theory shows that intera

## Abstract A three‐dimensional lattice model of protein designed to assimilate lysozyme is introduced. An attractive interaction is assumed to work between preassigned specific pairs of units, when they occupy the nearest‐nighbor lattice points. The behavior of this lattice lysozyme is studied by

## Synopsis It is suggested that the three-dimensional structure of globular proteins is partly determined by a framework of strengthened hydrogen bonds that involves both ionic side chains and water molecules in addition to the polypeptide backbone. This conclusion follows from a combination of t
