Approximation algorithms for survivable network design

Jabal Ameli, Afrouz ; Grandoni, Fabrizio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO005.

Many relevant discrete optimization problems are believed to be hard to solve efficiently (i.e. they cannot be solved in polynomial time unless P=NP). An approximation algorithm is one of the ways to tackle these hard optimization problems. These algorithms have polynomial running time and compute a feasible solution whose value is within a proven factor (approximation factor) of the optimal...

Digitally Enhanced Apprentices’ Perception of Connectivity Across Learning Locations

Amenduni, Francesca ; Cattaneo, Alberto

In: Pathways in Vocational Education and Training and Lifelong Learning. Proceedings of the 4th Crossing Boundaries Conference in Vocational Education and Training, Muttenz and Bern online, 8. – 9. April, 2021, p. 39-44

When crossing the borders from educational to professional environments, VET apprentices can perceive discontinuities and contradictions between what they learn at school and in the workplace. This research explores whether a digital tool named e- DAP, designed as a space for reflective practices in VET educational systems supports apprentices’ perception of connectivity across learning...

Benchmarking nonparametric Granger causality: Robustness against downsampling and influence of spectral decomposition parameters

Pagnotta, Mattia F. ; Dhamala, Mukesh ; Plomp, Gijs

In: NeuroImage, 2018, vol. 183, p. 478-494

Brain function arises from networks of distributed brain areas whose directed interactions vary at subsecond time scales. To investigate such interactions, functional directed connectivity methods based on nonparametric spectral factorization are promising tools, because they can be straightforwardly extended to the nonstationary case using wavelet transforms or multitapers on sliding time...

Detecting selection from linked sites using an f-model

Galimberti, Marco ; Leuenberger, Christoph ; Wolf, Beat ; Szilágyi, Sándor Miklós ; Foll, Matthieu ; Wegmann, Daniel

In: Genetics, 2020, vol. 216, no. 4, p. 1205–1215

Allele frequencies vary across populations and loci, even in the presence of migration. While most differences may be due to genetic drift, divergent selection will further increase differentiation at some loci. Identifying those is key in studying local adaptation, but remains statistically challenging. A particularly elegant way to describe allele frequency differences among populations...

A quantitative and qualitative analysis of the success of the smartwatch over Swiss luxury watch brands and how sustainable is this new threat

Arya, Rishikesh ; Furley, Sophie (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 100.

The aim of this research is to identify and understand how the smartwatch market has gained so much popularity in such a short period of time that it managed to surpass not only the Swiss luxury watch industry but the entire Swiss watch market in terms of sales volume globally. The study will focus on some critical quantitative and qualitative measures such as marketing, financials, consumer...

NESSi: The Non-Equilibrium Systems Simulation package

Schüler, Michael ; Golež, Denis ; Murakami, Yuta ; Bittner, Nikolaj ; Herrmann, Andreas ; U.R.Strand, Hugo ; Werner, Philipp ; Eckstein, Martin

In: Computer Physics Communications, 2020, vol. 257, no. 2020, p. 107484

The nonequilibrium dynamics of correlated many-particle systems is of interest in connection with pump–probe experiments on molecular systems and solids, as well as theoretical investigations of transport properties and relaxation processes. Nonequilibrium Green’s functions are a powerful tool to study interaction effects in quantum many-particle systems out of equilibrium, and to extract...

Corporate social responsibility and information and communication technology in the digital age

Schultz, Mario Dominik ; Seele, Peter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020COM003.

Pervasive digital technologies are transforming economies and societies worldwide. This dissertation focuses on Corporate Social Responsibilities (CSR) as the dominant model of business ethics over the last decades, in an attempt to better understand the digital transformation. Digitalization represents a fundamental and challenging transformation and promises to touch on almost all areas of...

Molecular connections between circadian clocks and mood-related behaviors

Albrecht, Urs

In: Journal of Molecular Biology, 2020, vol. 432, no. 12, p. 3714–3721

The circadian system consists of individual cellular clocks. It organizes and synchronizes biochemical and physiological processes in order to optimally adapt an organism to its environment. This requires that the circadian system is responsive to environmental cues, which contain information about geophysical time (e.g., light), and allows an organism to predict daily recurring events....

The significance of the adversative connectives aber, mais, ma (‘but’) as indicators in young children’s argumentation

Rocci, Andrea ; Greco, Sara ; Schär, Rebecca ; Convertini, Josephine ; Perret-Clermont, Anne-Nelly ; Iannaccone, Antonio

In: Journal of Argumentation in Context, 2020, vol. 69, no. 1, p. 69-94

Adversative connectives have been analyzed as articulating explicit and implicit facets of argumentative moves and have been thus recognized as potential argumentative indicators. Here we examine adversative connectives Ger. aber, Fr. mais, It. ma (‘but’) in young children’s speech in the context of the ArgImp project, a research endeavor seeking to understand in which...

The Dynamic Reorganization of Cortical Network Interactions during Visual Selective Attention

Pagnotta, Mattia ; Plomp, Gijs (Dir.)

Thèse de doctorat : Université de Fribourg, 2020.

Visual selective attention prioritizes the processing of behaviorally relevant over irrelevant information, to optimize the use of limited cognitive resources in the brain. These selective mechanisms preferentially route relevant neuronal representations through a network of distributed brain regions. Previous studies suggested that selective information routing in the attention network may...
