55. Coupling and reduction of hydro-ecological models for the simulation of freshwater aquatic ecosystems

joseph luis kahn casapia (INRIA MONTPELLIER)

03/12/2020 10:00

Algal Bloom is a natural process of rapid population growth of cyanobacteria (a group of photosynthetic bacteria) in aquatic environments, this is a consequence of the artificial enrichment caused by human activity. Our main objective is to build a hydro-ecological model to understand the dynamics of cyanobacteria in aquatic environments, taking into account the various essential factors for...

46. Optimization problem for a microalgal raceway pond to enhance productivity

Liudi Lu (Sorbonne Université & Inria)

03/12/2020 10:30

Microalgae are photosynthetic organisms whose potential has been proven in the last decade for several biotechnological applications (e.g.,Y. Chisti. Biodiesel from microalgae, Biotechnology Advances, 2007). These micro-organisms can be massively cultivated in closed or open photobioreactors. In this talk, we focus on the cultivation of algae in a raceway pond, where a paddle wheel is...

49. Three-dimensional modeling and experiment-driven numerical simulation of zebrafish escape swimming for biological applications

Guillaume Ravel (Université de Bordeaux)

03/12/2020 11:00

Swimming simulations are performed to study the performance of an active immersed body according to its shape and deforming movements. The deformation velocity of the body is usually imposed using a proper analytic formulation to model simple deforming movements. In the literature, more complex motions can be derived to model food, and prey captures (Bergmann et al.2011). To our knowledge,...

50. How can mathematics help someone with Glioblastoma Multiforme?

Flavien Alonzo (Doctorant)

03/12/2020 11:30

Glioblastoma Multiforme (GBM) is the deadliest and the most frequent brain tumour, only 5% of patients survive more than 5 years after being diagnosed. Patients go through emergency surgery and are being treated with both chemotherapy (Temozolomide) and radiotherapy. But those treatments still remain inefficient with that cancer because of the cellular heterogeneity.

In this work, the goal...

33. The Ocular Mathematical Virtual Simulator: a sensitivity analysis study

Lorenzo Sala (Inria Paris)

03/12/2020 12:00

Optic neuropathies such as glaucoma are often late-onset, progressive and incurable diseases.
Despite the recent progress in clinical research, there are still numerous open questions regarding the etiology of these disorders and their pathophysiology.
Furthermore, data on ocular posterior tissues are difficult to estimate noninvasively and their clinical interpretation remains challenging...

77. A Simple Cardiac Mitochondrial Model Validated Against Oxygen Consumption Measures Using a Global Senstivity Analysis Approach

Bachar Tarraf (phd student)

03/12/2020 12:30

Cardiac mitochondria are intracellular organelles that play an important role
in energy metabolism and cellular calcium regulation.
This is done through intra mitochondrial reactions and ionic fluxes across the
inner mitochondrial membrane.
In particular, cardiac mitochondria influence the excitation-contraction cycle of the heart cell.

We proposed previously a mathematical model of...
