Elucidating the Role of Matrix Stiffness in 3D Cell Migration and Remodeling

Matthias Lütolf, Adrian Ranga, Philipp Sebastian Lienemann, Katarzyna Mosiewicz, Martin Ehrbar

Reductionist in vitro model systems which mimic specific extracellular matrix functions in a highly controlled manner, termed artificial extracellular matrices (aECM), have increasingly been used to elucidate the role of cell-ECM interactions in regulating ...

MaSM: Efficient Online Updates in Data Warehouses

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis, Radu Ioan Stoica

Data warehouses (DW) have been traditionally optimized for readonly query performance, allowing only offline updates at night, essentially trading off data freshness for performance. The need for 24x7 operations in global markets and the rise of online and ...

Scientific diasporas from developing countries in Switzerland: empirical evidence and policy responses. Skilled migrants from Colombia, India and South Africa in Switzerland as partners in development

Jean-Claude Bolay, Gabriela Tejada Guerrero

Over the last two decades, globalisation has accelerated international migration flows, particularly of skilled labour. Yet increasing migration by skilled workers from developing countries («brain drain») has raised serious concerns internationally about ...

Evolution in heterogeneous populations From migration models to fixation probabilities

Séverine Vuilleumier Varisco, Nicolas Perrin

Although dispersal is recognized as a key issue in several fields of population biology (such as behavioral ecology population genetics metapopulation dynamics or evolutionary modeling) these disciplines focus on different aspects of the concept and often ...

ON CORRELATING BIRD MIGRATION TRAJECTORY WITH CLIMATE CHANGES

José Antonio Fernandes de Macedo, Janaina Oleinik Moura Rosa

Climate changes are expected to affect bird migration in several aspects including timing changes, breeding and migration orientation. The correlation analysis of several climate conditions (e.g. temperature, wind, humidity, etc) and bird migration traject ...

Self-organization in bird flight formations using diffusion adaptation

Ali H. Sayed

Flocks of birds self-organize into V-formations when they need to travel long distances. It has been shown that this formation allows the birds to save energy, by taking advantage of the upwash generated by the neighboring birds. In this work we use a simp ...

River Networks as Ecological Corridors: a Complex Systems Perspective for Integrating Hydrologic, Geomorphological and Ecologic Dynamics

Andrea Rinaldo, Enrico Bertuzzo

This paper synthesizes recent works at the interface of hydrology, geomorphology, and ecology under an integrated framework of analysis with an aim for a general theory. It addresses a wide range of related topics, including biodiversity of freshwater fish ...

Advanced Data Mining Method for Discovering Regions and Trajectories of Moving Objects: "Ciconia ciconia" Scenario

Stefano Spaccapietra, Claudio Magalhaes Carneiro

Trajectory data is of crucial importance for a vast range of applications involving analysis of moving objects behavior. Unfortunately, the extraction of relevant knowledge from trajectory data is hindered by the lack of semantics and the presence of error ...

Part I: A novel in-vitro system for simultaneous mechanical stimulation and time-lapse microscopy in 3D

Jeffrey Alan Hubbell

To investigate the migration response of cells to changes in their biophysical environment, a novel uniaxial cell stimulation device (UCSD) has been designed and tested. The device is capable of applying very precise user-defined static or dynamic mechanic ...
