Brown, M., Jacobs, T., Eickholt, B., Ferrari, G., Teo, M., Monfries, C., ...
Neurite outgrowth is influenced by positive and negative signals that include the semaphorins, an important family of axonal outgrowth inhibitors. Here we report that the Rac GTPase activating...
An extension of the Kac ring model (2003)
De Roeck, W., Jacobs, T., Maes, C., Netocny, K.
We introduce a unitary dynamics for quantum spins which is an extension of a model introduced by Mark Kac to clarify the phenomenon of relaxation to equilibrium. When the number of spins gets very...
Quantum Entropy Production as a Measure of (2002)
I. Callens, W. De Roeck, T. Jacobs, C. Maes
Considering closed and thermally isolated nite quantum systems, we derive that the total change of entropy, de ned for macroscopic trajectories, can be given in terms of a density matrix and its...
Quantum entropy production as a measure of irreversibility (2002)
Callens, I., De Roeck, W., Jacobs, T., Maes, C., Netocny, K.
We consider conservative quantum evolutions possibly interrupted by macroscopic measurements. When started in a nonequilibrium state, the resulting path-space measure is not time-reversal invariant...
Hall, C., Brown, M., Jacobs, T., Ferrari, G., Cann, N., Teo, M., ...
The formation and directional guidance of neurites involves dynamic regulation of Rho family GTPases. Rac and Cdc42 promote neurite outgrowth, whereas Rho activation causes neurite retraction. Here...

Neuronal differentiation involves Rac and Cdc42 GTPases. alpha -Chimaerin, a Rac/Cdc42 regulator, occurs as alpha 1- and alternatively spliced Src homology 2 (SH2) domain-containing alpha 2-isoforms....
Nonlinear Microwave Switching Response Of Bscco Single Crystals (1998)
T. Jacobs, Balam A. Willemsen, Qiang Li, G. D. Gu, N. Koshizuka
this paper was motivated by a chance observation during the study of the microwave response of high quality Bi 2 Sr 2 Ca 1 Cu 2 O8+ffi (BSCCO) single crystals. While measuring the surface impedance,...
