15 The long-term stability of microbiomes is crucial as the persistent occurrence of beneficial microbes and their associ16 ated functions ensure host health. Microbiomes are highly diverse and dynamic, but are they complex to the point of 17 being impossible to understand? We present an approach that while embracing this complexity it allows to identifying 18 meaningful patterns: the dynamic c...

In this paper we introduce the notion of protein interaction network. This is a graph whose vertices are the protein’s amino acids and whose edges are the interactions between them. Using a graph theory approach, we identify a number of properties of these networks. We compare them to the general small-world network model and we analyze their hierarchical structure. Keywords—interaction network...

Motivation: The use of multiple drugs, termed polypharmacy, is common to treat patients with complex diseases or co-existing medical conditions. However, a major consequence of polypharmacy is a much higher risk of adverse side effects for the patient. Polypharmacy side effects emerge because of drug-drug interactions, in which activity of one drug may change, favorably or unfavorably, if taken...

We introduce InVis, a novel visualization technique and tool for exploring, navigating, and understanding user interaction data. InVis creates a interaction network from student-interaction data extracted from large numbers of students using educational systems, and enables instructors to make new insights and discoveries about student learning. Here we present our novel interaction network mod...
