Interplay between Process Zone and Material Heterogeneities for Dynamic Cracks

In the context of dynamic fracture propagation along an heterogeneous domain, it has been shown in [1] how the presence of small-scale heterogeneities can impact the rupture dynamics of a crack. In the particular case of a mode-II crack propagating along a ...

Revealing Tumor Habitats from Texture Heterogeneity Analysis for Classification of Lung Cancer Malignancy and Aggressiveness

Adrien Raphaël Depeursinge

We propose an approach for characterizing structural heterogeneity of lung cancer nodules using Computed Tomography Texture Analysis (CTTA). Measures of heterogeneity were used to test the hypothesis that heterogeneity can be used as predictor of nodule ma ...

Atomistic-continuum coupling of random alloys

William Curtin, Till Junge, Shankha Nag

Random alloys are multicomponent systems where the atomic type on each lattice site is independent of the atom types on any other lattice site. The fluctuations in local atomic configurations inherent to the random alloy prevents the accurate application o ...

Applicability of Tail Corrections in the Molecular Simulations of Porous Materials

Berend Smit, Daniele Ongari, Kevin Maik Jablonka

Molecular simulations with periodic boundary conditions require the definition of a certain cutoff radius, r(c) beyond which pairwise dispersion interactions are neglected. For the simulation of homogeneous phases the use of tail corrections is well-establ ...

The detection of two-component mixture alternatives

Daria Rukina

In this thesis, we deal with one of the facets of the statistical detection problem. We study a particular type of alternative, the mixture model. We consider testing where the null hypothesis corresponds to the absence of a signal, represented by some kno ...

Logement de masse

Alessandro Porotto

This research has investigated the urban policies about mass housing at the beginning of 20th century. This was a unifying and crucial issue of several modern experiences to which many European cities developed adequate answers showing a wide range of dist ...

SENSITIVITY ANALYSIS OF A PATIENT SPECIFIC FINITE ELEMENT MODEL FOR SHOULDER ARTHOPLASTY

Gerard Guell Bartrina

Background Glenohumeral osteoarthritis is common degenerative disease within the elderly population, which causes pain and reduced mobility. In advanced cases, total shoulder arthroplasty (TSA) is usually performed. Although TSA is an established procedure ...

Graded-permittivity polymer nanocomposites as superior dielectrics

Yves Leterrier, Nicolas Mora Parra, Tommaso Nardi

Materials exhibiting a gradient in permittivity are synthesized through the application of an external magnetic field to a suspension of Fe3O4@TiO2 nanoparticles in an epoxy matrix. It is shown how the application of the magnetic field not only induces the ...

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Jher Hau Yeap

We recently reported a nonenzymatic biomass deconstruction process for producing carbohydrates using homogeneous mixtures of γ-valerolactone (GVL) and water as a solvent. A key step in this process is the separation of the GVL from the aqueous phase, enabl ...
