How does the collection and use of private data slow the development of eHealth solutions and which are the recommendations that can speed up innovation of eHealth solutions ?

Schuhmann Dos Santos, Antonio Joao ; Eggimann, Marc-André (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2018 ; TDEE 375.

The concept of eHealth was created in the late 1990s to automate and optimise healthcare. Even though various eHealth technologies exist nowadays, only some of them are available to consumers, while similar technologies are actually being used in other industries, such as the transportation industry. The aim of this paper is to understand how personal data can impact the development of eHealth...

From Asia to Europe : evaluation of parasitoids for the biological control of the invasive fruit pest "Drosophila suzukii"

Girod, Pierre ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

La production agricole est en constante évolution afin d’améliorer le rendement. Actuellement, 40% de la production agricole est perdue à cause des ravageurs des cultures (majoritairement des insectes exotiques). Leur contrôle est une des priorités majeures à laquelle les chercheurs font face aujourd’hui. Le commerce international et le changement climatique ont accéléré la...

Are meta-paths necessary?: revisiting heterogeneous graph embeddings

Hussein, Rana ; Yang, Dingqi ; Cudre-Mauroux, Philippe

In: Proceedings of the 27th ACM International Conference on Information and Knowledge Management, 2018, p. 437–446

The graph embedding paradigm projects nodes of a graph into a vector space, which can facilitate various downstream graph analysis tasks such as node classification and clustering. To efficiently learn node embeddings from a graph, graph embedding techniques usually preserve the proximity between node pairs sampled from the graph using random walks. In the context of a heterogeneous graph,...

Relation extraction using distant supervision: a survey

Smirnova, Alisa ; Cudré-Mauroux, Philippe

In: ACM Comput. Surv., 2018, vol. 51, no. 5, p. 106:1–106:35

Relation extraction is a subtask of information extraction where semantic relationships are extracted from natural language text and then classified. In essence, it allows us to acquire structured knowledge from unstructured text. In this article, we present a survey of relation extraction methods that leverage pre-existing structured or semi- structured data to guide the extraction process....

Change detection of bare-ice albedo in the Swiss Alps

Naegeli, Kathrin ; Huss, Matthias ; Hoelzle, Martin

In: The Cryosphere, 2019, vol. 13, no. 1, p. 397–412

Albedo feedback is an important driver of glacier melt over bare-ice surfaces. Light- absorbing impurities strongly enhance glacier melt rates but their abundance, composition and variations in space and time are subject to considerable uncertainties and ongoing scientific debates. In this study, we assess the temporal evolution of shortwave broadband albedo derived from 15 end-of-summer...

On the use of multiple-point statistics to improve groundwater flow modeling in karst aquifers : A case study from the Hydrogeological Experimental Site of Poitiers, France

Le Coz, M ; Bodin, J ; Renard, Philippe

In: Journal of Hydrology, 2017, vol. 545, p. 109-119

Limestone aquifers often exhibit complex groundwater flow behaviors resulting from depositional heterogeneities and post-lithification fracturing and karstification. In this study, multiple-point statistics (MPS) was applied to reproduce karst features and to improve groundwater flow modeling. For this purpose, MPS realizations were used in a numerical flow model to simulate the responses to...

Genomics of clinal variation in Drosophila: disentangling the interactions of selection and demography

Flatt, Thomas

In: Molecular Ecology, 2016, vol. 25, no. 5, p. 1023–1026

Clines in phenotypes and genotype frequencies across environmental gradients are commonly taken as evidence for spatially varying selection. Classical examples include the latitudinal clines in various species of Drosophila, which often occur in parallel fashion on multiple continents. Today, genomewide analysis of such clinal systems provides a fantastic opportunity for unravelling the...

How viruses hijack the ERAD tuning machinery

Noack, Julia ; Bernasconi, Riccardo ; Molinari, Maurizio

In: Journal of virology, 2014, vol. 88, no. 18, p. 10272-10275

An essential step during the intracellular life cycle of many positive-strand RNA viruses is the rearrangement of host cell membranes to generate membrane-bound replication platforms. For example, Nidovirales and Flaviviridae subvert the membrane of the endoplasmic reticulum (ER) for their replication. However, the absence of conventional ER and secretory pathway markers in virus-induced...

Life-history evolution and the polyphenic regulation of somatic maintenance and survival

Flatt, Thomas ; Amdam, Gro V. ; Kirkwood, Thomas B. L. ; Omholt, Stig W.

In: The Quarterly Review of Biology, 2013, vol. 88, no. 3, p. 185–218

Here we discuss life-history evolution from the perspective of adaptive phenotypic plasticity, with a focus on polyphenisms for somatic maintenance and survival. Polyphenisms are adaptive discrete alternative phenotypes that develop in response to changes in the environment. We suggest that dauer larval diapause and its associated adult phenotypes in the nematode (Caenorhabditis elegans),...

Increased temperature disrupts the biodiversity–ecosystem functioning relationship

Parain, Elodie C. ; Rohr, Rudolf P. ; Gray, Sarah M. ; Bersier, Louis-Félix

In: The American Naturalist, 2018, vol. 193, no. 2, p. 227–239

Gaining knowledge of how ecosystems provide essential services to humans is of primary importance, especially with the current threat of climate change. Yet little is known about how increased temperature will impact the biodiversity–ecosystem functioning (BEF) relationship. We tackled this subject theoretically and experimentally. We developed a BEF theory based on mechanistic population ...
