Tidskriftsartikel (refereegranskat)abstract
- Biological neurons are good examples of a threshold device - this is why neural systems are in the fetus when looking for realization of Stochastic Resonance (SR) and spatio-temporal stochastic resonance (STSR) phenomena. In this Letter a simple integrate

Spatiotemporal stochastic resonance and its consequences in neural model systems
- 2001
-
Ingår i: CHAOS. - : AMER INST PHYSICS. - 1054-1500. ; 11:3, s. 563-569
-
Tidskriftsartikel (refereegranskat)abstract
- The realization of spatiotemporal stochastic resonance is studied in a two-dimensional FitzHugh-Nagumo system, and in a one-dimensional system of integrate-and-fire neurons. We show that spatiotemporal stochastic resonance occurs in these neural model sys

Ag-Mn nanoparticles: Three-dimensional finite size effect of the spin glass state
- 1999
-
Ingår i: JOURNAL OF APPLIED PHYSICS. - : AMER INST PHYSICS. - 0021-8979. ; 86:11, s. 6571-6575
-
Tidskriftsartikel (refereegranskat)abstract
- Ag-Mn nanoparticles were prepared by advanced gas evaporation. Their composition corresponded to Ag0.89Mn0.11, and the particle size distribution was log normal. The particles demonstrated an unambiguous spin glass behavior with the temperature depen

NON-DYNAMICAL STOCHASTIC RESONANCE - THEORY AND EXPERIMENTS WITH WHITE AND VARIOUS COLORED NOISES

-
Tidskriftsartikel (refereegranskat)abstract
- We describe the simplest system which shows stochastic resonance. A linear(ized) theory for white and (almost) arbitrarily coloured noise is presented. The presented new system has new, unique properties which originate from its non-dynamical character; f

New approach to the origin of lognormal size distributions of nanoparticles
- 1999
-
Ingår i: NANOTECHNOLOGY. - : IOP PUBLISHING LTD. - 0957-4484. ; 10:1, s. 25-28
-
Tidskriftsartikel (refereegranskat)abstract
- A new model for particle growth can predict the well known lognormal particle size distribution from first principles in a physically realistic way. The model is completely different from the usually applied coagulation models; it is based on a reside
