Mathematical modeling of antigenicity for HIV dynamics

François Dubois, Hervé V.J. Le Meur, Claude Reiss (2010)

MathematicS In Action

Similarity:

This contribution is devoted to a new model of HIV multiplication motivated by the patent of one of the authors. We take into account the antigenic diversity through what we define “antigenicity”, whether of the virus or of the adapted lymphocytes. We model the interaction of the immune system and the viral strains by two processes. On the one hand, the presence of a given viral quasi-species generates antigenically adapted lymphocytes. On the other hand, the lymphocytes kill only viruses...

Flocking with informed agents

Felipe Cucker, Cristián Huepe (2008)

MathematicS In Action

Similarity:

Two similar Laplacian-based models for swarms with informed agents are proposed and analyzed analytically and numerically. In these models, each individual adjusts its velocity to match that of its neighbors and some individuals are given a preferred heading direction towards which they accelerate if there is no local velocity consensus. The convergence to a collective group swarming state with constant velocity is analytically proven for a range of parameters and initial conditions....

A quantitative study of the rate of change in Spanish employment.

Antoni Espasa (1984)

Qüestiió

Similarity:

In this paper the homogeneous information available for the Spanish economy on employment, productivity and wages is processed by means of annual single equation models. The aim in this exercise is to fix ideas about the fundamental characteristics that dominate the relationships between the mentioned data. A set of conclusions is listed at the end of the paper.
