Mechanical properties of peripheral stress fibers in adherent cells spreading on patterned substrates

Céline Jeanne Labouesse

Many cellular processes require or depend on mechanical feedback from the cell's micro-environment. For example, the local organization of the actin cytoskeleton is known to adapt to the physical properties of the extracellular matrix. To gain better under ...

Cell Shape Dynamics Reveal Balance of Elasticity and Contractility in Peripheral Arcs

Jean-Jacques Meister, Chiara Gabella, Alexander Verkhovskiy, Benoît Vianay, Céline Jeanne Labouesse

The mechanical interaction between adherent cells and their substrate relies on the formation of adhesion sites and on the stabilization of contractile acto-myosin bundles, or stress fibers. The shape of the cell and the orientation of these fibers can be ...

Dynamic aggregation of the mid-sized gadolinium complex {Ph-4[Gd(DTTA)(H2O)(2)](-)(3)}

Lothar Helm, Hugues Jaccard, Pascal Miéville

A compound binding three Gd3+ ions, {Ph-4Gd(DTTA)(H2O)(2) (3)} (where H(5)DTTA is diethylenetriaminetetraacetic acid), has been synthesized around a hydrophobic center made up of four phenyl rings. In aqueous solution the molecules start to self-aggre ...

Bedrock topography reconstruction of glaciers from surface topography and mass-balance data

Marco Picasso, Laurent Michel, Heinz Blatter, Martin Funk

Three methods based on the three-dimensional shallow ice approximation of glacier flow are devised that infer a glacier's subglacial topography from the observation of its time-evolving surface and mass balance. The quasi-stationary inverse method relying ...

Phase-field modeling of micropore formation in a solidifying alloy

Hossein Meidani

This thesis is focused on the study of the morphology of micropores formed during solidification of metallic alloys. Micropores constrained to form in well-developed dendritic solid network adopt complex non-spherical shapes. Previous studies using X-ray t ...

Modélisation physique et analyse numérique de la propagation d'une masse granulaire : contribution à l'étude des avalanches rocheuses

Claire Sauthier

Rock avalanches are processes involving a huge amount of mobilised material, larger than 106 m3, and their propagation is characterised by a very high energy, such that no active mitigation measure is capable of protecting human lives and properties potent ...

Ideal knots and other packing problems of tubes

Henryk Gerlach

This thesis concerns optimal packing problems of tubes, or thick curves, where thickness is defined as follows. Three points on a closed space curve define a circle. Taking the infimum over all radii of pairwise-distinct point triples defines the thickness ...

Saturation of curvature-induced secondary flow, energy losses, and turbulence in sharp open-channel bends: Laboratory experiments, analysis, and modeling

Koen Blanckaert

The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry ...

Nonlinear Stability of Riemann Ellipsoids with Symmetric Configurations

Using modern differential geometric methods, we study the relative equilibria for Dirichlet's model of a self-gravitating fluid mass having at least two equal axes. We show that the only relative equilibria of this type correspond to Riemann ellipsoids for ...
