A generalized fission-fusion model for the frequency of severe terrorist attacks (2009)

Clauset, Aaron, Wiegel, Frederik W.

We present and analyze a model of the frequency of severe terrorist attacks, which generalizes the recently proposed model of Johnson et al. This model, which is based on the notion of...

Kinetics of ligand binding to a cluster of membrane-associated receptors (1994)

Potanin, Andrew A., Verkhusha, Vladyslav V., Belokoneva, Olga S., Wiegel, Frederik W.

The process of ligand binding to a cluster of membrane-associated receptors is examined theoretically. The theoretical model proposed involves the diffusion of ligands from the solution to the...

Chemoreception by a cell with age-dependent receptor binding sites (1990)

Geurts, Bernard J., Wiegel, Frederik W.

The authors determine the time-dependent ligand current into a spherical cell that is covered with a large number of age-dependent receptors. These receptor can be either of two states: active (i.e.,...

Chaotic motion of a harmonically bound charged particle in a magnetic field, in the presence of a half-plane barrier (1990)

Geurts, Bernard J., Wiegel, Frederik W., Creswick, Richard J.

The motion in the plane of an harmonically bound charged particle interacting with a magnetic field and a half-plane barrier along the positive x-axis is studied. The magnetic field is perpendicular...

Exact quantum-mechanical propagator for an electron in a saddle-point potential and a magnetic field (1989)

Damme Van, Ruud, Wiegel, Frederik W., Harrison, Michael J.

We study the time-dependent propagator for an electron which moves in a plane and which is subject to quadrupolar electric fields with certain reflection symmetries, and to a uniform magnetic field...

Crosslinking and gelation between linear polymers: DNA-antibody complexes in systemic lupus erythematosus (1987)

Wiegel, Frederik W., Geurts, Bernard J., Goldstein, Byron

In the autoimmune disease systemic lupus erythematosus the DNA molecules of an individual are attacked by its own antibodies. As these antibodies are bivalent they can crosslink different DNA...

Some Design Principles for Immune System Recognition

Alan S. Perelson, Frederik W. Wiegel

The immune system is a complex system that learns, remembers what it has learned, and acts to protect us from a variety of pathogens. Here we address the question of how the immune system is able to...
