Asbestos case and its current implications for global health

Annali dell'Istituto Superiore di Sanità, 2013
Notwithstanding a major body of evidence on the carcinogenicity of all asbestos fibres and a general consensus of the scientific community on the health impact of this agent, asbestos is still produced and used in a large number of countries, thus ...

On the High-dimensional Bak-Sneppen model

, 1998
We report on extensive numerical simulations on the Bak-Sneppen model in high dimensions. We uncover a very rich behavior as a function of dimensionality.

Capital flow in a two-component dynamical system

, 1999
A model of open economics composed of producers and speculators is investigated by numerical simulations. The capital flows from the environment to the producers and from them to the speculators.

Continuum time limit and stationary states of the Minority Game

, 2001
We discuss in detail the derivation of stochastic differential equations for the continuum time limit of the Minority Game. We show that all properties of the Minority Game can be understood by a careful theoretical analysis of such equations.

When is coffee not coffee? Luigi Ferdinando Marsigli's depictions of the coffee plant in “Notizie, di Costantinopoli; sopra la pianta del caffè” (1703) [PDF]

Italian Botanist
The late 17th and early 18th centuries were an era in which the coffee drink was first becoming known throughout Europe, and there was a strong interest in disseminating what the plant looked like through the use of botanical illustrations.

Laplacian Fractal Growth in Media with Quenched Disorder

, 1997
We analyze the combined effect of a Laplacian field and quenched disorder for the generation of fractal structures with a study, both numerical and theoretical, of the quenched dielectric breakdown model (QDBM).

Dynamics of Fractures in Quenched Disordered Media

, 1998
We introduce a model for fractures in quenched disordered media. This model has a deterministic extremal dynamics, driven by the energy function of a network of springs (Born Hamiltonian).

Influence of external information in the minority game

, 2003
The influence of a fixed number of agents with the same fixed behavior on the dynamics of the minority game is studied. Alternatively, the system studied can be considered the minority game with a change in the comfort threshold away from half filling ...

Simulation of Intramolecular Hydrogen Bond Dynamics in Manzamine A as a Sensitive Test for Charge Distribution Quality

Natural Product Communications, 2012
Subtle balance of inter- and intramolecular hydrogen bond strength in aqueous solutions often governs the structure and dynamics of molecular species used as potential drugs and in supramolecular applications.
