A New Platform for Editing Digital Multimedia : the eTalks
The eTalks are a new digital multimedia editing plaform developed at the University of Lausanne: their application is implemented via an easy-to-use editor interface, designed for the use of researchers themselves, to create and edit original eTalks. This permits the linking together of images, sounds and textual materials with hyperlinks, enriching it with relevant information. The final release of eTalks allows complete ‘citability’ of its contents: each and every portion of the researchers' talks can be precisely referred to and thus cited with a specific identifier, just like any traditional, paper-based scientific publication but with all the potential for plural literacies. It is openly accessible and the code is open source, including guidelines to install the eTalks. It contributes to the development of multiliteracies in the digital academic production of knowledge
Landauer vs. Nernst: What is the True Cost of Cooling a Quantum System?
Thermodynamics connects our knowledge of the world to our capability to
manipulate and thus to control it. This crucial role of control is exemplified
by the third law of thermodynamics, Nernst's unattainability principle, stating
that infinite resources are required to cool a system to absolute zero
temperature. But what are these resources and how should they be utilised? And
how does this relate to Landauer's principle that famously connects information
and thermodynamics? We answer these questions by providing a framework for
identifying the resources that enable the creation of pure quantum states. We
show that perfect cooling is possible with Landauer energy cost given infinite
time or control complexity. However, such optimal protocols require complex
unitaries generated by an external work source. Restricting to unitaries that
can be run solely via a heat engine, we derive a novel Carnot-Landauer limit,
along with protocols for its saturation. This generalises Landauer's principle
to a fully thermodynamic setting, leading to a unification with the third law
and emphasising the importance of control in quantum thermodynamics.Comment: 15 pages, 4 figures, 46 pages of appendice

L'arrivée du lecteur en exégèse biblique: a-t-on ouvert la boîte de Pandore de l'interprétation sans limite ?
Tout-ski. La fin d’un mythe ?
L’acceptation de l’initiative pour la limitation des résidences secondaires a constitué un véritable choc pour les régions touristiques suisses. En replaçant cette décision dans le contexte plus général du débat sur les avantages et les inconvénients d’un modèle de développement des stations basé sur la construction de résidences secondaires, nous rappelons tout d’abord le rôle jusqu’ici restreint joué en Suisse par les pouvoirs publics dans la gestion de cette problématique. Nous montrons également le décalage existant entre le discours des responsables politiques et touristiques, favorable à une restriction de la construction de nouvelles résidences secondaires, et la réalité du terrain matérialisée par une augmentation continuelle de ces dernières. Notre hypothèse principale consiste à affirmer que la modification du cadre légal imposée par l’acceptation de l’initiative va contraindre les acteurs du tourisme à innover afin de mettre en place un nouveau modèle de développement basé sur l’hébergement marchand, autrement dit à passer d’un « tourisme de construction » à un « tourisme d’exploitation »
