Graph neural networks : operators and architectures

Grattarola, Daniele ; Alippi, Cesare (Dir.) ; Livi, Lorenzo (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO014.

This thesis explores the field of graph neural networks, a class of deep learning models designed to learn representations of graphs. We organise the work into two parts. In the first part, we focus on the essential building blocks of graph neural networks. We present three novel operators for learning graph representations: one graph convolutional layer and two methods for pooling. We put...

Epilepsy-associated neurocognitive disorders (EAND) in an onchocerciasis-endemic rural community in Cameroon : A population-based case–control study

K.Njamnshi, Alfred ; Chokote, Eric-Samuel ; Ngarka, Leonard ; Nfor, Leonard N. ; Tabaha, Earnest N. ; Basseguin Atchou, Jonas G. ; Angwaforbe, Samuel A. ; Nkouonlack, Cyrille ; Mengnjo, Michel K. ; Njamnshi, Wepnyu Y. ; Demaa, Fidèle ; Tataha, Godwin Y. ; Zoung-KanyiBissek, Anne-Cecile ; Annoni, Jean-Marie ; Ruffieux, Nicolas

Epilepsy affects at least 50 million individuals worldwide, especially in sub-Saharan Africa (sSA). Cognitive impairment is common in people with epilepsy (PWE) yet, little is known on the burden of cognitive impairment in people with epilepsy in sSA. This study was thus designed to assess cognitive impairment in PWE or epilepsy- associated neurocognitive disorders (EAND) in a rural...

The immunomodulatory effects of macrolides - a systematic review of the underlying mechanisms

Zimmermann, Petra ; Ziesenitz, Victoria C. ; Curtis, Nigel ; Ritz, Nicole

In: Frontiers in Immunology, 2018, vol. 9, p. -

The mechanisms underlying the non-antimicrobial immunomodulatory properties of macrolides are not well understood.Objectives: To systematically review the evidence for the immunomodulatory properties of macrolides in humans and to describe the underlying mechanism and extent of their influence on the innate and adaptive immune system.Methods: A systematic literature search was done in MEDLINE...

Stereological analysis of the rhesus monkey entorhinal cortex

Piguet, Olivia ; Chareyron, Loïc J. ; Lavenex, Pamela Banta ; Amaral, David G. ; Lavenex, Pierre

In: Journal of Comparative Neurology, 2018, vol. 526, no. 13, p. 2115–2132

The entorhinal cortex is a prominent structure of the medial temporal lobe, which plays a pivotal role in the interaction between the neocortex and the hippocampal formation in support of declarative and spatial memory functions. We implemented design‐based stereological techniques to provide estimates of neuron numbers, neuronal soma size, and volume of different layers and subdivisions of...
