Configurational entropy of adsorbed particles on two-dimensional heterogeneous surfaces

Romá, F.; Ramirez-Pastor, A.J. - In: Physica A: Statistical Mechanics and its Applications 328 (2003) 3, pp. 513-524

The configurational entropy of repulsive interacting particles adsorbed on heterogeneous surfaces is studied by combining Monte Carlo simulation and thermodynamic integration method. The substrate is represented by a bivariate lattice characterized by l×l patches of weak and strong adsorbing...

Tracer diffusion of dimers on correlated heterogeneous surfaces

Bulnes, F.; Bustingorry, S.; Ramirez-Pastor, A.J. - In: Physica A: Statistical Mechanics and its Applications 330 (2003) 3, pp. 409-414

The diffusion of a single dimer adsorbed on highly correlated heterogeneous substrates is studied through Monte Carlo simulations. The topography has been characterized by patches of weak and strong adsorbing sites, arranged in a chessboard-like ordered structure. The time behavior of the...

A real options perspective on R&D portfolio diversification

Bekkum, Sjoerd van; Pennings, Enrico; Smit, Han T. J. - 2008

This paper shows that the presence of conditional staging in R&D (Research & Development) has a critical impact on portfolio risk, and changes diversification arguments when a portfolio is constructed. When R&D projects exhibit option-like characteristics, correlation between projects plays a...
