QLS Seminar TODAY - Thu. 15 May at 14h00 - "Flow of Information in Living Systems" by Arnab Saha, U. Calcutta

[Quantitative Life Sciences]

Dear All,

Today,  Thursday, 15 May at 14:00 CET, Prof. Arnab Saha (Department of 
Physics, University of Calcutta, India) will give a seminar titled:

*"*Flow of Information in Living Systems *"

*_Abstract:

_Living entities in a group communicate and transfer information to one 
another for a variety of reasons. It might be for foraging food, 
migration, or escaping from obstacles and threats that may appear 
suddenly. They do so by interacting with each other and also with the 
environment. Statistical mechanics and information theory can be useful 
to develop the tools to quantify and analyse the flow of information 
among the living entities. The living entities can be modelled as active 
(i.e. self-propelling) particles. Here we consider a group of active 
particles under confinement. First we will show that the 
self-organisation of the particles can crucially depend on whether the 
confinement is soft or hard. Then we quench the trap boundary from soft 
to hard instantaneously. Consequently the self-organised cluster of the 
active particles, which was stable when the boundary was soft, becomes 
unstable and undergoes extreme deformation after the quench to find 
another stable configuration suitable for the hard boundary. Finally we 
will quantify the information regarding the quench that flows throughout 
the individual particles of the deforming cluster and show that the flow 
spans the whole cluster, propagating ballistically.
