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.

An understanding of the numerous anomalies of water is closely linked to an
understanding of the phase diagram of the metastable non-crystalline states of ice. The discovery of high- (HDA) and low-density amorphous ice (LDA)  prompted the question whether this phenomenon of polyamorphism is connected to the occurrence of more than one supercooled liquid phase. In case of LDA the connection to the low-density liquid (LDL) was inferred from several experiments including the observation of a calorimetric glass-to-liquid
transition at 136 K . However, in case of HDA instead no calorimetric signature has been detected so far.
Experiments using differential scanning calorimetry (DSC) and dielectric spectroscopy show for the first time that HDA transforms into a liquid upon heating at ambient pressure . The glass-to-liquid transition upon heating is
evidenced by an endothermic step, which indicates that the liquid has a higher heat capacity than the glass due to an increase of molecular mobility, e.g., by unfreezing of translational motion. In our measurements the corresponding calorimetric signature occurs at 116 K. This glass transition can also be detected by dielectric spectroscopy via the appearance of an absorption peak centred at about 10–2 Hz. From the temperature dependent peak positions a relaxation map can be constructed. The good agreement between dielectric and calorimetric results convey for a clearer picture of water's vitrification phenomenon.
