We deeply regret to have to inform that on 28 May 2016 after a period of serious illness Professor Eligiusz Wajnryb passed away. He was an acclaimed researcher who made progress in the fields of fluid mechanics and neuroinformatics and the author of many significant scientific papers. He will always be our sorely missed colleage, collaborator and friend.

Processes of Brownian particles in fluids
ü Applications
of Dynamical Systems and Stochastic Processes to Biological Systems: Neural
Networks, DNA
Major Contributions
o Hydrodynamic
Interactions: Development of HDROMULTIPOLE code,
used by many authors, for evaluating the Stokesian trajectories and
hydrodynamical mobilities and friction. Numerous applications: effective
transport coefficients in suspensions, dynamics of flexible fibers.
o Stochastic
Processes: Investigation of the Smoluchowski
approach to the Brownian motion of colloidal particles - effective low
frequency transport coefficients, modelling the aggregation of polymers subject
to the external flows.
o
Information Transmission: Application of Shannon Communication Theory to the analysis of neuronal
signals, entropy, mutual information, complexity, Lempel-Ziv algorithms, source
information classifications.
