Deep neural networks learn representations of data to facilitate problem-solving in their respective domains. However, they struggle to acquire a structured representation based on more symbolic entities, which are commonly understood as core abstractions central to human capacity for generalization. This dissertation studies this issue for visual reasoning tasks. Inspired by how humans solve...

The binary compound V3Ga can exhibit two near-equilibrium phases, the A15 structure that is superconducting and the Heusler D03 structure that is semiconducting and antiferromagnetic. Density functional theory calculations show that these two phases are nearly degenerate, being separated in energy by only ±10 meV/atom. Our magnetization measurements on bulk-grown samples show ...

In vitro three-dimensional (3D) lung cell models have been thoroughly investigated in recent years and provide a reliable tool to assess the hazard associated with nanomaterials (NMs) released into the air. In this study, a 3D lung co-culture model was optimized to assess the hazard potential of multiwalled carbon nanotubes (MWCNTs), which is known to provoke inflammation and fibrosis,...

A human alveolar cell coculture model is described here for simulation of the alveolar epithelial tissue barrier composed of alveolar epithelial type II cells and two types of immune cells (i.e., human monocyte-derived macrophages [MDMs] and dendritic cells [MDDCs]). A protocol for assembling the multicellular model is provided. Alveolar epithelial cells (A549 cell line) are grown and...

Hydrogenolysis of tertiary benzylic alcohols on palladium on carbon (Pd/C) generally proceeds with inversion of configuration. However, little is known about the hydrogenolysis mechanism of primary and secondary benzylic alcohols. Literature precedents suggest that these substrates may interact differently with the catalyst. To study the mechanism, we synthesized a pair of deuterated...

Les troubles de la production écrite de type dysgraphie de surface font partie des critères diagnostiques de la variante sémantique de l’aphasie primaire progressive (APP-s). Cependant, un recensement des études décrivant les différents patterns de difficultés orthographiques des patients APP-s met en évidence que si l’atteinte de la voie d’adressage, dans les modèles séquentiels,...

The arrival of new organisms that may potentially become harmful for people and ecosystems has become a world-wide daily concern to the point that in Switzerland about 800 established alien species exist, of which at least 107 are considered invasive. A possible way to control such pests is by importing and releasing natural enemies from their countries of origin, letting them to act as so-called...

The present PhD thesis includes three different projects which belong to the domain of inner-shell atomic physics and high energy resolution X-ray spectroscopy. The first project consists of a series of in-house measurements of the characteristic K and L X-ray absorption spectra (XAS) of several 3d, 4d and 5d transition metals. For this project the target chamber of the von Hamos curved crystal...
