Semantic content in titi monkey alarm call sequences

Berthet, Mélissa ; Zuberbühler, Klaus (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

The comparative approach aims to understand the uniqueness of human language and how it evolved from primitive communication systems. Black-fronted titi monkeys Callicebus nigrifrons possess two soft alarm calls: A-calls are specific to threats within the canopy while B-calls are general calls emitted to terrestrial predators but also in non-predatory contexts, while moving near the...

Stress und seine Bedeutung in der Kindheit : die Messung von frühen Stressoren und möglichen Folgen auf die psychische Gesundheit von Vorschulkindern

Stülb, Kerstin ; Munsch, Simone (Dir.)

Thèse de doctorat : Université de Fribourg, 2018.

Early adversities such as critical live events or cumulative everyday challenges might exceed individual coping strategies or resources and thus lead to pathological changes in the long term. Maladaptive physiological and psychological processes as a consequence of dysfunctional stress response are the basis of these changes. Preschool age plays an important role in this context, since the...

Deciphering the complexity of human noncoding promoter-proximal transcriptome : different scales of transcriptional control : from a single gene to the whole epigenome

Mapelli, Sarah Natalia ; Krause, Rolf (Dir.) ; Catapano, Carlo V. (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO001.

Long noncoding RNAs (lncRNAs) have gained increasing interest in molecular studies, their active participation in important biological functions has emerged and their direct involvement in genomic reprogramming during development and diseases, including cancer, has been demonstrated. Several studies have shown their active contribution in transcriptional control and they are emerging as...

Large scale geometry of box spaces

Delabie, Thiebout ; Valette, Alain (Dir.) ; Khukhro, Ana (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Box spaces are metric space that are constructed using group. They are useful as examples of metric spaces with exceptional large scale geometric properties. In this thesis we further investigate box space.

Hydrogeological characterization of karst aquifers in Switzerland using a pragmatic approach

Malard, Arnauld ; Jeannin, Pierre-Yves (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Recent studies reveal that karst aquifers represent a significant part of the Swiss groundwater reserve (120 km3) and resource (8.4 km3/year), although they only extend over 20% of the territory. On the one hand, high infiltration rates and large permeabilities of karstified rocks make karst aquifers highly interesting for water management. On the other hand, karst...

Isoperimetric inequalities for Laplace and Steklov problems on Riemannian manifolds

Pétiard, Luc ; Colbois, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

This thesis is about the spectra of the Laplacian and of the Dirichlet-to-Neumann operators on a compact Riemannian manifold. Both problems have physical interpretations that can be found in [Eva 1998] and [Ban 1980]. We focused on finding upper bounds for the eigenvalues, based on the geometry of the manifold. More precisely, we consider if it is possible to obtain upper bounds in which the...

Erasure coding for distributed storage systems

Barbi, Roberta ; Mercier, Hughes (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

A huge quantity of data is generated and stored every day. Preeminent examples are the 300 million photos that get uploaded daily to Facebook or the 156 million emails sent every minute. Furthermore, it is remarkable that almost 90% of the data in the world has been generated in the last 2 years. This humongous quantity of data is typically hosted in data centres located in different geographic...

Hydrogeological and topographical controls on catchment dynamics and their implications for low flows

Carlier, Claire ; Brunner, Philip (Dir.) ; Hunkeler, Daniel (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Periods with scarce precipitation will likely occur more frequently and last longer under changing climatic conditions, even in relatively humid regions like Switzerland. To assess the sensitivity of water resources to dry spells and to identify regions that might experience water scarcity issues, a thorough understanding of the mechanisms governing catchment dynamics in the absence of rain is...

Predicting the spatial correlation of daily streamflows to understand the hydrological response of river networks

Betterle, Andrea ; Schirmer, Mario (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Rivers are fascinating expressions of the hydrological cycle and their waters, riparian areas and floodplains harbor a multitude of ecosystems. The potential for rivers to sustain life depends on the dynamics of water quantity – and quality – that are critically controlled by catchment-scale geomorphoclimatic processes. In particular, the temporal and spatial availability of streamflows is...
