In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Turbulent Transport of Extended and Interacting Particles: Beyond the Spherical Particle Approximation
(International Center for Theoretical Sciences, Tata Institute of Fundamental Research, Bangalore)
A string of tracers, interacting elastically, in a turbulent flow,
shows a dramatically different behaviour when compared to the non-interacting
case. Such an elastic chain shows strong preferential sampling of the turbulent
flow unlike the usual tracer limit: an elastic chain is trapped in the vortical
regions. The degree of preferential sampling and its dependence on the
elasticity of the chain is quantified via the Okubo-Weiss parameter. The effect
of modifying the deformability of the chain, via the number of links that form
it, is also examined. We then end with recent results which suggest that
suitable choice of particle interactions can lead to either crystalline phases
in particle-aggregates or collective behaviour reminiscent of flocking in the
