Reva and CERNBox: developments and prospected evolution / Geens, Jesse (speaker) ; Lo Presti, Giuseppe (speaker) (CERN)
In this contribution we will touch on the recent developments and the operational experience running Reva as part of CERNBox, the CERN cloud storage, and on our plans to support Reva and the CS3APIs for the community. Having the CS3APIs reached a good level of maturity, in the past year we consolidated the Reva implementation and improved its dependability, in particular with respect to sharing, on one hand, and to supporting the two main storages, EOS and CephFS, on the other. On the operations side, we will share our experience in integrating external applications, and we show how we intend to provision storage with different QoS fulfilling the multiple requirements of our diverse user community. We will conclude with an outlook on the CS3APIs governance and on our plans to evolve CERNBox as a sync & share ecosystem for the community..

Simulating Bell inequalities with Qibo / Masina, Isabella (INFN, Ferrara ; U. Ferrara (main)) ; Lo Presti, Giuseppe (CERN) ; Robbiati, Matteo (CERN ; Milan U.) ; Grossi, Michele (CERN)
We present educational material about Bell inequalities in the context of quantum computing. In particular, we provide software tools to simulate their violation, together with a guide for the classroom discussion. [...]

OCM State of the Art / Lo Presti, Giuseppe (speaker) (CERN)
This presentation will set the scene for the Campfire session. The current state of the specification and its latest evolution will be presented, with reference to the ScienceMesh infrastructure and the CS3 community at large. A number of questions will be raised, which can be discussed in the Panel discussion that will follow the topical lightning talks..

Triad’s consonance and dissonance: combining roughness and compactness models / Masina, Isabella (Ferrara U. ; INFN, Ferrara) ; Lo Presti, Giuseppe (CERN)
Theories of consonance and dissonance based on the “roughness” approach are those that explain these perceptions as due to the primary beatings between harmonics. Originally proposed by Helmholtz, this approach has been very popular in the last century, being naturally associated to continuous functions of the frequency ratios, on the contrary of theories based on the “compactness” approach.

The Physics of Music from Pythagoras to Microtones / Masina, Isabella (speaker) (Universita e INFN, Ferrara (IT)) ; Lo Presti, Giuseppe (speaker) (CERN)
Abstract:What are the physical foundations of Western music? Why are there 12 notes in an octave? Why is Equal Temperament so successful? What is the role of microtones in music composition? In this lecture series we will try to answer these and many other questions, that might have come to the mind of scientists playing an instrument from amateur to semi-professional level. In the first lecture, starting from the case study of the vibrating string, we first review harmonic sounds and timbre in the context of Signal Theory. We then introduce the psychoacoustic notions of "roughness", Critical Bandwidth and Discrimination Limen. [...]

Applications integration beyond local clouds with OCM / Lo Presti, Giuseppe (speaker) (CERN)
The Open Cloud Mesh (OCM) protocol has been adopted as part of the ScienceMesh infrastructure to enable interactive and agile collaboration across various file synchronization and sharing providers at a pan-European level. With such infrastructure emerging as the collaboration space across institutions, an important added value is the ability to open document files and work with other collaborators, by exploiting concurrent editing capabilities of common online editors such as Collabora and CodiMD. In this presentation, we demonstrate the work done towards integrating applications on top of OCM-shared files, both in terms of OCM extensions and web UI, and how this enables organizations that are part of ScienceMesh to share their application engines. We discuss licensing issues related to such cross-sites use cases, and we conclude with future prospects in the landscape of collaborative apps for cloud storage systems..
