The ML-EM algorithm in continuum: sparse measure solutions
Camille Pouchol, Olivier Verdier
Linear inverse problems with Poisson noise and non-negative unknown are ubiquitous in applications, for instance in Positron Emission Tomography (PET) in medical…
Spatiotemporal PET reconstruction using ML-EM with learned diffeomorphic deformation
Ozan Öktem, Camille Pouchol, Olivier Verdier
Patient movement in emission tomography deteriorates reconstruction quality because of motion blur. Gating the data improves the situation somewhat: each gate contains a movement p…
Asymptotic analysis of selection-mutation models in the presence of multiple fitness peaks
Tommaso Lorenzi, Camille Pouchol
We study the long-time behaviour of phenotype-structured models describing the evolutionary dynamics of asexual species whose phenotypic fitness landscape is characterised by multi…
Hele-Shaw limit for a system of two reaction-(cross-)diffusion equations for living tissues
Federica Bubba, Benoît Perthame, Camille Pouchol +1
Multiphase mechanical models are now commonly used to describe living tissues including tumour growth. The specific model we study here consists of two equations of mixed parabolic…
