Lagrangian Numerical Approximations to One-Dimensional Convolution-Diffusion Equations

This work focuses on the numerical analysis of one-dimensional nonlinear diffusion equations involving a convolution product. First, homogeneous friction equations are considered. Algorithms follow recent ideas on mass transportation methods and lead to simple schemes which can be proved to be…

Transmission conditions obtained by homogenisation

Given a bounded open set in [Formula presented], [Formula presented], and a sequence [Formula presented] of compact sets converging to an [Formula presented]-dimensional manifold [Formula presented], we study the asymptotic behaviour of the solutions to some minimum problems for integral…

ICF-specific DNMT3B dysfunction interferes with intragenic regulation of mRNA transcription and alternative splicing.

Hypomorphic mutations in DNA-methyltransferase DNMT3B cause majority of the rare disorder Immunodeficiency, Centromere instability and Facial anomalies syndrome cases (ICF1). By unspecified mechanisms, mutant-DNMT3B interferes with lymphoid-specific pathways resulting in immune response defects.…

Coupling quadrature and continuous Runge-Kutta methods for optimal control problems

This paper deals with the numerical solution of optimal control problems for ODEs. The approach is based on the coupling between quadrature rules and continuous Runge-Kutta solvers and it lies in the framework of direct optimization methods and recursive discretization techniques. The…

Image Scaling by de la Vallée-Poussin Filtered Interpolation

We present a new image scaling method both for downscaling and upscaling, running with any scale factor or desired size. The resized image is achieved by sampling a bivariate polynomial which globally interpolates the data at the new scale. The method's particularities lay in both the sampling…

Anisotropic Diffusion and Curve Evolution for Segmentation of Color Images in Cultural Heritage

Fluidization and wall slip of soft glassy materials by controlled surface roughness

We present a comprehensive study of concentrated emulsions flowing in microfluidic channels, one wall of which is patterned with micron-size equally spaced grooves oriented perpendicularly to the flow direction. We find a scaling law describing the roughness-induced fluidization as a function of…
