The self-organization of cells into a living organism is a very intricate process. Under the surface of orchestrating regulatory networks there are physical processes which make the information processing possible, that is required to organize such a multitude of individual entities. We use a quantitative information theoretic approach to assess self-organization of a collective system. In part...

The mechanical and rheological behaviour of particulate granular assemblies is significantly influenced by the shape their individual particles. We present a code that implements characterisation three-dimensional particles in an automated rigorous manner, allowing for processing samples composed thousands irregular within affordable time runs. input particle geometries can be provided one foll...

We study the influence of particle shape on evolution breakage process taking place inside rotating cylinders. Extensive dynamics simulations into account granular flow, breakage, and polygonal shapes were carried out. find that rate is faster in samples composed initially rounder particles. The analysis active flowing layer thickness suggests for particles a relatively lower dilatancy higher c...

In many cases, the accuracy of statistical pixel classification can be improved by applying a spatially varying prior that can be derived from a shape model. We propose to represent the prior knowledge on the spatial distribution of tissue classes by a distribution of shape particles, each representing one possible distribution of tissue classes. Classification and shape can then be optimized j...
