Multilevel minimization in trust-region framework : algorithmic and software developments

Kopaničáková, Alena ; Krause, Rolf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO021.

The field of scientific computing is associated with the modeling of complex physical phenomena. The resulting numerical models are often described by differential equations, which, in many cases, can be related to non-convex minimization problems. Thus, after discretization, the solution of large-scale non-convex optimization problem is required. Various iterative solution strategies can be...

Advanced metaheuristics for the probabilistic orienteering problem

Chou, Xiaochen ; Gambardella, Luca Maria (Dir.) ; Montemanni, Roberto (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO020.

Stochastic Optimization Problems take uncertainty into account. For this reason they are in general more realistic than deterministic ones, meanwhile, more difficult to solve. The challenge is both on modelling and computation aspects: exact methods usually work only for small instances, besides, there are several problems with no closed-form expression or hard- to-compute objective functions....

Self-avoiding walk on $\mathbb{Z}^{2}$ with Yang–Baxter weights: Universality of critical fugacity and 2-point function

Glazman, Alexander ; Manolescu, Ioan

In: Annales de l’Institut Henri Poincaré, Probabilités et Statistiques, 2020, vol. 56, no. 4, p. 2281–2300

We consider a self-avoiding walk model (SAW) on the faces of the square lattice Z2. This walk can traverse the same face twice, but crosses any edge at most once. The weight of a walk is a product of local weights: each square visited by the walk yields a weight that depends on the way the walk passes through it. The local weights are parametrised by angles θ∈[π3,2π3] and satisfy the...

Identification of avoidance genes through neural pathway-specific forward optogenetics

Marques, Filipe ; Saro, Gabriella ; Lia, Andrei-Stefan ; Poole, Richard J. ; Falquet, Laurent ; Glauser, Dominique A.

In: PLOS Genetics, 2019, vol. 15, no. 12, p. e1008509

Understanding how the nervous system bridges sensation and behavior requires the elucidation of complex neural and molecular networks. Forward genetic approaches, such as screens conducted in C. elegans, have successfully identified genes required to process natural sensory stimuli. However, functional redundancy within the underlying neural circuits, which are often organized with multiple...

Occupational career patterns over 30 years: predictors and outcomes

Schellenberg, Claudia: Interkantonale Hochschule für Heilpädagogik ; Krauss, Annette ; Hättich, Achim ; Häfeli, Kurt

In: Empirical Research in Vocational Education and Training, 2016, vol. 8, no. 15, p. 1-22

Background: Investigating individuals’ sequences of occupations and identifying suitable patterns is a complex task. Most research focuses on single time-points, single jobs and single transitions and only few longitudinal studies have investigated career paths over a long period of time. The aim of this study is to describe occupational career patterns (OCP) over a period of 30 years using...

Intermediality and the discursive construction of popular music genres: the case of ‘Japanese City Pop’

Sommet, Moritz

In: Handai ongaku gakuhō / Journal of Handai Music Studies, 2020/16/17//15-42

Commonly said to embody the 'urbane' and 'refined' lifestyle of metropolitan Tokyo and to prefigure the transnational and consumerist characteristics of today's mainstream J-Pop, Japanese City Pop has undergone several recontextualizations since it first surfaced in the last quarter of the 20th century. I use City Pop as an example to interrogate the intermedial qualities of the processes at...

Circadian and genetic modulation of visually-guided navigation in Drosophila larvae

Asirim, Ece Z. ; Humberg, Tim-Henning ; Maier, G. Larisa ; Sprecher, Simon G.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 2752

Organisms possess an endogenous molecular clock which enables them to adapt to environmental rhythms and to synchronize their metabolism and behavior accordingly. Circadian rhythms govern daily oscillations in numerous physiological processes, and the underlying molecular components have been extensively described from fruit flies to mammals. Drosophila larvae have relatively simple nervous...

Software documentation : automation and challenges

Aghajani, Emad ; Lanza, Michele (Dir.) ; Bavota, Gabriele (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO014.

Despite the undeniable practical benefits of documentation during software development and evolution activities, its creation and maintenance is often neglected, leading to inadequate and even inexistent documentation. Thus, it is not unusual for developers to deal with unfamiliar code they have difficulties in comprehending. Browsing the official documentation, or accessing online resources,...

Who is included in VET, who not?

Scharnhorst, Ursula ; Kammermann, Marlise

In: Education + Training, 2020, vol. 62, no. 6, p. 645-658

Purpose The paper describes the Swiss Vocational Education and Training (VET) system, its crucial role and challenges with respect to the inclusion of vulnerable groups and investigates the effectiveness of the efforts undertaken to promote inclusion in VET so far. Design/methodology/approach Empirical research focusing on various indicators of inclusion (national monitoring data and own studies)...
