A New Framework for Unidimensional Structures Based on Generalised Continua
Mewen Crespo, Casale Guy, Loïc Le Marrec +1
The present work introduces a family of beam models derived from a three-dimensional higher-order elasticity framework. By incorporating three kinematic fields - the macroscopic di…
A novel attention mechanism for noise-adaptive and robust segmentation of microtubules in microscopy images
Achraf Ait Laydi, Louis Cueff, Mewen Crespo +2
Segmenting cytoskeletal filaments in microscopy images is essential for studying their roles in cellular processes. However, this task is highly challenging due to the fine, densel…
Defects in unidimensional structures
Mewen Crespo, Guy Casale, Loïc Le Marrec +1
In a previous work of the first authors, a non-holonomic model, generalising the micromorphic models and allowing for curvature (disclinations) to arise from the kinematic values,…
Two-Scale Geometric Modelling for Defective Media
Mewen Crespo, Guy Casale, Loïc Le Marrec
A new geometrically exact micro-structured model is constructed using a generalisation of the notion of Riemann-Cartan manifolds and fibre bundle theory of rank 3. This model is ba…
