Crosstalk 1. Surmounting barriers cooperatively
Speaker. Prof. K. L. Sebastian.
Title. Surmounting barriers cooperatively
Abstract. Many a times, long chain biological molecules have to pass through nano-sized pores. Entering a pore is a constraint, which results in a decrease of entropy or in other words, increase in free energy. Thus, the molecule has to cross a free energy barrier in space. Because of these biological examples, passage of long chain molecules have been studied in vitro too. Motivated by this we consider the process of passage of a long chain molecule over a free energy barrier. Interestingly, the simplest model for the process would be a chain of drunken walkers, climbing over a hill. One can find analytical solutions for simplest possible model for such systems, known as the Rouse model. Within this model, we find that calculating the activation energy for the process is (mathematically) equivalent to calculting the exponent in a quantum mechanical tunneling problem. Using this, it is easy to see that for a long enough molecule, the activation energy has to be independent of the length of the molecule. Further, a long enough molecule will cross the barrier with a steady velocity which is determined by the “steadily moving kink” like solutions of the associated non-linear equation. As a result, the time that it takes for the molecule to cross over the barrier is proportional to its length. The relevance of the results to biology will be quickly outlined.
If time permits, and if there is sufficient interest, my experiences in publishing the results too will be outlined, and it will be stressed how useful I found the arXiv.org to be.

Crosstalk 5. Designs For Purpose: Nature is a Brilliant Designer!
Speaker. Dr. Padmesh A.
Title: Designs For Purpose: Nature is a Brilliant Designer!
Abstract. The talk will introduce you through different molecular assemblies ( specifically the macromolecules) in living systems, their organisation and functions, giving emphasize on PROTEINS (polypeptides). To conclude, a small polypeptide is investigated to understand its structural preference.
