School on Understanding Molecular Simulations Theory and Applications
Molecular Simulations have become a very useful tool to analyze various phenomena in physical, chemical and biological systems. With the advent of better computational facilities, there has been a significant push towards a molecular level analysis. Many complex problems in condensed matter systems like protein folding are regularly investigated using molecular simulation techniques. This school aims to provide the conceptual foundations and working knowledge of molecular simulations. The participants will also be exposed to programming and other technical aspects of molecular simulation. In addition, applications ranging from materials to biology will be showcased. The ten day program will include lectures, tutorial and hands-on computer training sessions conducted by the experts in the field. The proposed school will help the young researchers and students go beyond the usual curriculum of molecular simulation and statistical mechanics practised in academic institutions.

Advanced School on Living Mechanics - cells tissues and organisms
Mechanical signalling has emerged as an important regulator of cell biology and physiology. Forces, flows and fluctuations can have remarkable influences on the properties of molecules, cells, tissues and organs. How living systems generate, sense and transduce mechanical stimuli, and what consequences these have for development and disease are questions that are intrinsically interdisciplinary and have captured the interests not just of biologists but also engineers, mathematicians and theoretical physicists.The school will bring together leading researchers engaged in understanding the active mechanical principles regulating an amazing diversity of biological systems over a variety of length scales using experimental and theoretical interdisciplinary approaches. The program will combine pedagogy and research with leisurely and detailed scientific interactions and serve to train advanced students, postdocs and faculty from India and abroad in this young and rapidly growing area at the...

Groups Actions Computations 2010
This program combines a workshop and conference covering a broad range of modern and currently very active areas of the theory of finite groups, encompassing computational techniques as well as applications. In particular, general techniques for matrix and permutation groups, the classification of and computations with p-groups, an introduction to finite simple groups, and actions of finite groups on Riemann surfaces will be addressed.The program will have two parts:Workshop, September 01-09, 2010, consisting of some five series of four two-hour lectures each, aiming at introducing graduate students and young post-doctoral researchers to these fields. In particular, guided practical instructions to the use of the computer algebra system GAP will be included.Conference, September 10-12, 2010, leading to the frontiers of current research. Experts in the above fields will present new and recent research results. This is intended both to disseminate results and current problems across the ...

Application of Control Theory And Optimisation Techniques In Biochemical Pathways
Control theory is concerned with designing strategies that ensure the robust performance of a system by automatically adapting to changes in the environment. Biochemical pathways in the cell are responsible for processing environmental signals, inducing appropriate cellular responses, and regulating internal events such as gene expression. Through elaborate mechanisms, they allow cells and entire organisms to perform their basic functions. The key role played by feedback in life are manifested in the homeostatic control and regulation of biochemical pathways, which break down nutrients and provide the cell with energy and materials, and their appropriate timing in functions. Recent years have witnessed remarkable advances in elucidating the components of cellular pathways and networks of genes. They provide a snapshot of the complete genetic activity of a cell, yet the overall connectivity and functional characteristics are still poorly understood - a fundamental lacuna in understand...
