Soil mapping using electro-magnetic methods: development of a unified constitutive model.

In the context of sustainable development, there is a growing interest in mapping soil characteristics and land use, in particular to evaluate threats to soil quality. Fast non-invasive geophysical surveys have been used to estimate the areal distribution ...

A general basis for quarter-power scaling in animals

Andrea Rinaldo, Amos Maritan

It has been known for decades that the metabolic rate of animals scales with body mass with an exponent that is almost always 2/3, and often very close to 3/4. The 3/4 exponent emerges naturally from two models of resource distribution networks, radia ...

Obtaining molecular orientation from second harmonic and sum frequency scattering experiments in water: angular distribution and polarization dependence

Sylvie Roke

We present a method for determining molecular orientation from second-order nonlinear light scattering experiments. Our modeling shows that there is an optimal angular region, for which the scattering pattern is most sensitive to molecular orientation. We ...

Rat model: neural substrates of the battered woman syndrome

Xavier Fontana

This study is part of a long term study on a male rat model of peripubertal stress in the Laboratory of Behavioural Genetics that shows increase aggressive behaviours against their partners. We are using here these rats in order to create a female rat mode ...

Effective Spin Model for the Spin-Liquid Phase of the Hubbard Model on the Triangular Lattice

Frédéric Mila

We show that the spin-liquid phase of the half-filled Hubbard model on the triangular lattice can be described by a pure spin model. This is based on a high-order strong coupling expansion ( up to order 12) using perturbative continuous unitary transformat ...

Harnessing bacterial power in microscale actuation

Mahmut Selman Sakar

This paper presents a systematic analysis of the motion of microscale structures actuated by flagellated bacteria. We perform the study both experimentally and theoretically. We use a blotting procedure to attach flagellated bacteria to a buoyancy-neutral ...

Three- and four-element Windkessel models: assessment of their fitting performance in a large cohort of healthy middle-aged individuals

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

Lumped-parameter models are used to estimate the global arterial properties by fitting the model to measured (aortic) pressure and flow. Different model configurations coexist, and it is still an open question as to which model optimally reflects the arter ...

Two-dimensional quantum antiferromagnet with a fourfold degenerate dimer ground state

Frédéric Mila

We study the competition between antiferromagnetic order and valence-bond-crystal formation in a two-dimensional frustrated spin-1/2 model. The J(1)-J(2) model on the square lattice is further frustrated by introducing products of three-spin projectors whi ...

Mechanical characterization of a dielectric elastomer microactuator with ion-implanted electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...

Mécanismes rétroactifs de ségrégation, entre une société urbaine et son espace : Un modèle basé agents

André Ourednik

This paper describes an agent-based model of socio-spatial segregation, result of a synthesis between « Schelling’s spatial segregation model » and a demographc model of dependency between household fertility rates and socio-economical status of their desc ...
