A bioinspired multi-modal flying and walking robot
No full textWith the aim to extend the versatility and adaptability of robots in complex environments, a novel multi-modal flying and walking robot is presented. The robot consists of a flying wing with adaptive morphology that can perform both long distance flight and walking in cluttered environments for local exploration. The robotʼs design is inspired by the common vampire bat Desmodus rotundus, which can perform aerial and terrestrial locomotion with limited trade-offs. Wings' adaptive morphology allows the robot to modify the shape of its body in order to increase its efficiency during terrestrial locomotion. Furthermore, aerial and terrestrial capabilities are powered by a single locomotor apparatus, therefore it reduces the total complexity and weight of this multi-modal robot.NCCR-ROBOTICSLI
Who is the author of the 1876 Stefano manuscript?
Full text linkFor over one hundred years the Stefano manuscript was a private document in the possession of the Baccich family and descendants. It told a story of the 1875 Stefano shipwreck as narrated by the shipwreck survivor and the founding family patriarch Miho Baccich. In these circumstances the question of authorship of the manuscript was immaterial and did not arise as an issue. However, with the publication of the manuscript the author‟s name, or names, need to be formally attributed to it. It turns out that this is not such a clear-cut matter.
As we shall see, all informed sources attributed the authorship, and the ownership, of the manuscript to Miho Baccich. But the manuscript itself was written by Canon Stjepan Skurla – a priest from Miho‟s hometown of Dubrovnik. The question then arises: should Skurla also be considered as an author of the manuscript, or, even as the sole author (as some would have it)
Fashion Culture: Power In Fashion with Stefano Tonchi and Grazia d'Annunzio

The green leafhopper, cicadella viridis (hemiptera, auchenorrhyncha, cicadellidae), jumps with near-constant acceleration
No full textJumping insects develop accelerations that can greatly exceed gravitational acceleration. Although several species have been analysed using different tools, ranging from a purely physical to a morpho-physiological approach, instantaneous dynamic and kinematic data concerning the jumping motion are lacking. This is mainly due to the difficulty in observing in detail events that occur in a few milliseconds. In this study, the behaviour of the green leafhopper, Cicadella viridis, was investigated during the take-off phase of the jump, through high-speed video recordings (8000 frames s-1). We demonstrate that C. viridis is able to maintain fairly constant acceleration during overall leg elongation. The force exerted at the foot-ground interface is nearly constant and differs from the force expected from other typical motion models. A biomechanical model was used to highlight that this ability relies on the morphology of C. viridis hind legs, which act as a motion converter with a variable transmission ratio and use the time-dependent musculo-elastic force to generate a nearly constant thrust at the body-ground interface. This modulation mechanism minimizes the risk of breaking the substrate thanks to the absence of force peaks. The results of this study are of broad relevance in different research fields ranging from biomechanics to robotics. © 2013. Published by The Company of Biologists Ltd
Introduzione [a I cartolari del notaio Stefano di Corrado di Lavagna]
No full textSaggio introduttivo all’edizione dei frammenti dei protocolli del notaio Stefano di Corrado di Lavagna nel quale viene fatta l’analisi codicologica dei frammenti e si ricostruisce la biografia del notaio. Vengono inoltre esaminate la tipologia dei documenti, le tecniche redazionali del notaio e l’organizzazione burocratica della Chiesa genovese nella seconda metà del secolo XIII.
Introduction essay to the edition of the fragments of the protocols of the notary Stefano di Corrado of Lavagna in which the analysis of the codex fragments and reconstructs the biography of the notary is made by the author. She also examined the types of documents, the technical drafting of the notary and the bureaucratic organization of the Church of Genoa in the second half of the thirteenth century
From Lausanne to Luxembourg: the CJEU’s Seraing Judgment and the Boundaries of Sports Arbitration Under EU Law
No full textIn this expert analysis, Professor Stefano Bastianon dissects the CJEU’s landmark Seraing ruling (Case C-600/23), which reshapes the contours of sports arbitration under EU law. With particular focus on judicial review and EU public policy, the author explores how the Court balances the autonomy of arbitral mechanisms like CAS with the imperative of effective judicial protection — a judgment that could have far-reaching implications for the future of dispute resolution in sport
