Multiscale methods for Stokes flow in heterogeneous media

Fluid flow in porous media is a multiscale process where the effective dynamics, which is often the goal of a computation, depends strongly on the porous micro structure. Resolving the micro structure in the whole porous medium can, however, be prohibitive ...

Chemical Genetic Screen Identifies Natural Products that Modulate Centriole Number

Kai Johnsson, Pierre Gönczy, Michele Graciotti, Zhou Fang

Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...

Microfluidic chip for monitoring Ca2+ transport through a confluent layer of intestinal cells

Martinus Gijs, Paolo Silacci, Hüseyin Cumhur Tekin, Josias Basil Wacker, Christine Ruffert, Guy Vergères

The absorption of dietary calcium through the intestinal barrier is essential for maintaining health in general and especially of the bone system. We propose a microfluidic model that studies free calcium (Ca2+) transport through a confluent monolayer of C ...

Multi-Scale Approach for Modeling Desiccation Shrinkage in Granular Soils

Lyesse Laloui

This paper aims to identify and quantitatively evaluate various critical mechanisms associated with the processes of desiccation shrinkage and cracking in drying silty soils. A previously developed 1D bundle-of-tubes model is refined to simulate the variou ...

Emerging predictable features of replicated biological invasion fronts

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...

Microtechnologies to Map the Fate of Single Stem Cells and their Progeny

Stefan Kobel

Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...

Dispersal strategies, few dominating or many coexisting: the effect of environmental spatial structure and multiple sources of mortality

Séverine Vuilleumier Varisco

Interspecific competition, life history traits, environmental heterogeneity and spatial structure as well as disturbance are known to impact the successful dispersal strategies in metacommunities. However, studies on the direction of impact of those factor ...

Single-Cell Analysis of Mycobacterial Persistence Using Microfabricated Tools

Meltem Elitas

Bacterial cells behave as individuals despite being genetically identical and subject to the same environment. Although the underlying mechanisms of cellular individuality are not well understood, temporal variation of gene expression and protein levels in ...

Sample preparation microfluidic cartridge for on-line adjustment of osmolarity in miniaturized cell-based analysis systems

Nico de Rooij, Peter Van der Wal, Sara Talaei

Cell based biosensors are increasingly used as detection tools for tracing toxins in environmental samples. In such biosensors the reaction of cells cultivated in vitro is monitored upon exposing them to different samples. As the sample will be in close co ...

Hydrologic controls and anthropogenic drivers of the zebra mussel invasion of the Mississippi-Missouri river system

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

We propose a novel ecohydrological model for the invasion of inland waters by the zebra mussel Dreissena polymorpha and test it against field data gathered within the Mississippi-Missouri river system in North America. This biological invasion poses major ...
