Octree Optimized Micrometric Fibrous Microstructure Generation for Domain Reconstruction and Flow Simulation.

Over recent decades, tremendous advances in the field of scalable numerical tools and mesh immersion techniques have been achieved to improve numerical efficiency while preserving a good quality of the obtained results. In this context, an octree-optimized microstructure generation and domain reconstruction with adaptative meshing is presented and illustrated through a flow simulation example applied to permeability computation of micrometric fibrous materials. Thanks to the octree implementation, the numerous distance calculations in these processes are decreased, thus the computational complexity is reduced.

[Young athletes and doping in sports].

Young athletes and doping in sports. Prevalence of doping among young athletes (whether children or adolescents) reaches 3 to 5%. In France, this result means that, on average, 240.

Dose to organ at risk and dose prescription in liver SBRT.

Stereotactic body radiation therapy (SBRT) is delivered in a curative intent to many primary and secondary tumors. Concerning liver metastasis, SBRT can be safely delivered using one to five fractions. An excellent local control is obtained with doses from 20 to 60 Gy.

[Health of adolescents restricted under court order: self-esteem, perceived parental support, projects].

Objective: To describe certain aspects of the physical and mental health of adolescents with restricted or deprived liberty as ordered by the court within the Youth Judicial Protection Service (YJP), and their ability to project themselves into the future.

Methods: Survey by on-line self-administered questionnaires.

Population: Among the adolescents, 373 were randomly selected with restricted or deprived liberty, in the Lorraine region (eastern France).
