Optimization of anchor nodes placement in wireless localization networks

Balac, Katarina ; Malek, Miroslaw (Dir.) ; Prevostini, Mauro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO009.

This work focuses on optimizing node placement for time-of-flight-based wireless localization networks. Main motivation are critical safety applications. The first part of my thesis is an experimental study on in-tunnel vehicle localization. In- tunnel localization of vehicles is crucial for emergency management, especially for large trucks transporting dangerous goods such as inflammable...

A privacy-aware and secure system for human memory augmentation

Bexheti, Agon ; Langheinrich, Marc (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO011.

The ubiquity of digital sensors embedded in today's mobile and wearable devices (e.g., smartphones, wearable cameras, wristbands) has made technology more intertwined with our life. Among many other things, this allows us to seamlessly log our daily experiences in increasing numbers and quality, a process known as ``lifelogging''. This practice produces a great amount of pictures and videos...

Modeling user information needs on mobile devices : from recommendation to conversation

Aliannejadi, Mohammad ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO010.

Recent advances in the development of mobile devices, equipped with multiple sensors, together with the availability of millions of applications have made these devices more pervasive in our lives than ever. The availability of the diverse set of sensors, as well as high computational power, enable information retrieval (IR) systems to sense a user’s context and personalize their results ...

When and how java developers give up static type safety

Mastrangelo, Luis ; Hauswirth, Matthias (Dir.) ; Nystrom, Nathaniel (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO008.

The main goal of a static type system is to prevent certain kinds of errors from happening at run time. A type system is formulated as a set of constraints that gives any expression or term in a program a well-defined type. Besides detecting these kinds of errors, a static type system can be an invaluable maintenance tool, can be useful for documentation purposes, and can aid in generating ...

Adjuvants and the vaccine response to the DS-Cav1-stabilized fusion glycoprotein of respiratory syncytial virus

Sastry, Mallika ; Zhang, Baoshan ; Chen, Man ; Joyce, M. Gordon ; Kong, Wing-Pui ; Chuang, Gwo-Yu ; Ko, Kiyoon ; Kumar, Azad ; Silacci, Chiara ; Thom, Michelle ; Salazar, Andres M. ; Corti, Davide ; Lanzavecchia, Antonio ; Taylor, Geraldine ; Mascola, John R. ; Graham, Barney S. ; Kwong, Peter D.

In: Plos one, 2017, vol. 12, no. 10, p. e0186854

Appropriate adjuvant selection may be essential to optimize the potency and to tailor the immune response of subunit vaccines. To induce protective responses against respiratory syncytial virus (RSV)—a highly prevalent childhood pathogen without a licensed vaccine—we previously engineered a pre-fusion-stabilized trimeric RSV F (pre-F) “DS-Cav1” immunogen, which induced high titer...

Phenotype and specificity of T cells in primary human cytomegalovirus infection during pregnancy : IL-7Rpos long-term memory phenotype is associated with protection from vertical transmission

Mele, Federico ; Fornara, Chiara ; Jarrossay, David ; Furione, Milena ; Arossa, Alessia ; Spinillo, Arsenio ; Lanzavecchia, Antonio ; Gerna, Giuseppe ; Sallusto, Federica ; Lilleri, Daniele

In: Plos one, 2017, vol. 12, no. 11, p. e0187731

Congenital human cytomegalovirus (HCMV) infection is the major cause of birth defects and a precise definition of the HCMV-specific T-cell response in primary infection may help define reliable correlates of immune protection during pregnancy. In this study, a high throughput method was used to define the frequency of CD4+ and CD8+ T cells specific for four HCMV proteins in the naïve...

Molecular signatures of immunity and immunogenicity in infection and vaccination

Haks, Mariëlle C. ; Bottazzi, Barbara ; Cecchinato, Valentina ; De Gregorio, Corinne ; Del Giudice, Giuseppe ; Kaufmann, Stefan H. E. ; Lanzavecchia, Antonio ; Lewis, David J. M. ; Maertzdorf, Jeroen ; Mantovani, Alberto ; Sallusto, Federica ; Sironi, Marina ; Uguccioni, Mariagrazia ; Ottenhoff, Tom H. M.

In: Frontiers in immunology, 2017, vol. 8, p. 1563

Vaccinology aims to understand what factors drive vaccine-induced immunity and protection. For many vaccines, however, the mechanisms underlying immunity and protection remain incompletely characterized at best, and except for neutralizing antibodies induced by viral vaccines, few correlates of protection exist. Recent omics and systems biology big data platforms have yielded valuable...

Transcriptional signature of human pro-inflammatory TH17 cells identifies reduced IL10 gene expression in multiple sclerosis

Hu, Dan ; Notarbartolo, Samuele ; Croonenborghs, Tom ; Patel, Bonny ; Cialic, Ron ; Yang, Tun-Hsiang ; Aschenbrenner, Dominik ; Andersson, Karin M. ; Gattorno, Marco ; Pham, Minh ; Kivisakk, Pia ; Pierre, Isabelle V. ; Lee, Youjin ; Kiani, Karun ; Bokarewa, Maria ; Tjon, Emily ; Pochet, Nathalie ; Sallusto, Federica ; Kuchroo, Vijay K. ; Weiner, Howard L.

In: Nature communications, 2017, vol. 8, p. 1600

We have previously reported the molecular signature of murine pathogenic TH17 cells that induce experimental autoimmune encephalomyelitis (EAE) in animals. Here we show that human peripheral blood IFN-γ+IL-17+ (TH1/17) and IFN-γ−IL-17+ (TH17) CD4+ T cells display distinct transcriptional profiles in high-throughput transcription analyses. Compared to TH17 cells, TH1/17 cells have gene...

Epigenetic and transcriptional control of mast cell responses

Monticelli, Silvia ; Leoni

In: F1000 research, 2017, vol. 6, p. 2064

Mast cells are tissue-resident, innate immune cells present in most tissues of the body and are important effector and immunomodulatory cells. Differentiated mast cells typically are characterized by the surface expression of the receptors KIT and FcεRI, the latter especially being important for stimulation through IgE antibodies, although these cells have the ability to respond to a wide...

TRPM7 kinase activity is essential for T cell colonization and alloreactivity in the gut

Romagnani, Andrea ; Vettore, Valentina ; Rezzonico-Jost, Tanja ; Hampe, Sarah ; Rottoli, Elsa ; Nadolni, Wiebke ; Perotti, Michela ; Meier, Melanie A. ; Hermanns, Constanze ; Geiger, Sheila ; Wennemuth, Gunther ; Recordati, Camilla ; Matsushita, Masayuki ; Muehlich, Susanne ; Proietti, Michele ; Chubanov, Vladimir ; Gudermann, Thomas ; Grassi, Fabio ; Zierler, Susanna

In: Nature communications, 2017, vol. 8, p. 1917

The melastatin-like transient-receptor-potential-7 protein (TRPM7), harbouring a cation channel and a serine/threonine kinase, has been implicated in thymopoiesis and cytokine expression. Here we show, by analysing TRPM7 kinase-dead mutant (Trpm7 R/R) mice, that the enzymatic activity of the receptor is not essential for thymopoiesis, but is required for CD103 transcription and gut-homing of ...
