Oriented basement membrane fibrils provide a memory for F-actin planar polarization via the Dystrophin-Dystroglycan complex during tissue elongation

How extracellular matrix contributes to tissue morphogenesis is still an open question. In the Drosophila ovarian follicle, it has been proposed that after Fat2-dependent planar polarization of the follicle cell basal domain, oriented basement membrane (BM) fibrils and F-actin stress fibers constrain follicle growth, promoting its axial elongation. However, the relationship between BM fibrils...

Liquid web applications : design and implementation of the decentralized cross-device web

Gallidabino, Andrea ; Pautasso, Cesare (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO006.

Web applications are traditionally designed having in mind a server-centric architecture, whereby the whole persistent data, dynamic state and logic of the application are stored and running on a Web server. The clients running in the Web browsers traditionally render only pre-computed views fetched from the server. Nowadays this centralized approach does not fit well with the kind of...

Le développement de la richesse lexicale en langue de scolarisation et en langue d'origine

Bonvin, Audrey

In: Bulletin VALS-ASLA, 2020, vol. Spécial, p. 141-160

This paper compares short narrative and argumentative texts written by migrant Portuguese-speaking children in Switzerland to those written by Portuguese-speaking children living in Portugal as well as French-speaking and German-speaking children in Switzerland. This contribution focuses on human intuitive perception of the richness of vocabulary. Our corpus comprises of 3,060 French, German and...

The last surviving Thalassochelydia — A new turtle cranium from the Early Cretaceous of the Purbeck Group (Dorset, UK)

Anquetin, Jérémy ; André, Charlotte

In: PaleorXiv, 2020, p. 7pa5c

Background. The mostly Berriasian (Early Cretaceous) Purbeck Group of southern England has produced a rich turtle fauna dominated by the freshwater paracryptodires Pleurosternon bullockii and Dorsetochelys typocardium. Each of these species is known by numerous relatively complete shells and by a single cranium. The two other turtles found in the Purbeck Group (Hylaeochelys belli, a species of...

Essays in household finance and monetary policy transmission

Gianinazzi, Virginia ; Plazzi, Alberto (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO005.

This thesis consists of three chapters that contribute to two fundamental questions in finance: how households make financial decisions and how market prices react to uninformative demand shocks. The first chapter investigates how household respond to mortgage refinancing incentives. A well-documented finding in household finance is that many borrowers miss out on substantial savings by...

γδ T cells kill Plasmodium falciparum in a granzyme- and granulysin-dependent mechanism during the late blood stage

Hernández-Castañeda, Maria Andrea ; Happ, Katharina ; Cattalani, Filippo ; Wallimann, Alexandra ; Blanchard, Marianne ; Fellay, Isabelle ; Scolari, Brigitte ; Lannes, Nils ; Mbagwu, Smart Ikechukwu ; Fellay, Benoît ; Filgueira, Luis ; Mantel, Pierre-Yves ; Walch, Michael

In: The Journal of Immunology, 2020, vol. 204, no. 7, p. 1798–1809

Plasmodium spp., the causative agent of malaria, have a complex life cycle. The exponential growth of the parasites during the blood stage is responsible for almost all malaria-associated morbidity and mortality. Therefore, tight immune control of the intraerythrocytic replication of the parasite is essential to prevent clinical malaria. Despite evidence that the particular lymphocyte subset ...

Human-robot interaction with pointing gestures : intuitive interaction between co-located humans and robots

Gromov, Boris ; Gambardella, Luca Maria (Dir.) ; Giusti, Alessandro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO004.

Human-robot interaction (HRI) is an active area of research and an essential component for the effective integration of mobile robots in everyday environments. In this PhD work, we studied, designed, implemented, and experimentally validated new efficient interaction modalities between humans and robots that share the same workspace. The core of the work revolves around deictic (pointing)...

Secrecy in the age of transparency : an investigation into legitimations, conceptions and practices of non-disclosure

Heide, Marlen ; Villeneuve, Jean-Patrick (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019COM004.

The objective of this research is to illustrate the complexity and fluidity of the relationship between secrecy and transparency by considering the multiple rationales that serve to justify secrecy. The conceptual contribution of this thesis lies at two levels: (1) the reconceptualization of national security secrecy from realism to risk management and (2) the implications of such...

Participation in Energy Transition : The Potential and the Coordination of Energy Communities

Hertig, Yves ; Teufel, Stephanie (Dir.)

Thèse de doctorat : Université de Fribourg, 2019.

The Swiss electricity sector aims to have a future that is greener, cheaper, fairer and more reliable. With the approval of the new Energy Act (EnA), politicians and society anticipate a more participative role of Swiss households concerning such major energy-related aims. However, the question arises whether such expectations are actually justified. This thesis relativizes major expectations...

Labour market outcomes : Careers, transitions and durations

Malfitano, Paolo ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO004.

This thesis contributes to labour economics by considering a wide range of factors influencing career paths, transitions to self- employment and duration in entrepreneurship. In the past literature, several studies have analysed labour market outcomes, transitions and durations. Nevertheless, there is the need of knowing more about the influence of individual and background characteristics on...
