Pattern formation in the brain
Science, 2017Neurodevelopment Neurons in the developing brain cooperate to build circuits. Mountoufaris et al. found that ∼50 variable protocadherin genes support a combinatorial identity code that allows millions of olfactory neuron axons to sort into ∼2000 glomeruli.

A fundamental question in biology is how biological patterns emerge. Because of the presence of numerous confounding factors, it is tremendously challenging to elucidate the mechanisms underlying pattern formation solely on the basis of studies of natural biological systems.

The Pattern Formation problem is one of the most important coordination problem for robotic systems. Initially the entities are in arbitrary positions; within finite time they must arrange themselves in the space so to form a pattern given in input. In this chapter, we will mainly deal with the problem in the OBLOT model.

Publisher Summary This chapter focuses on the concept of optical pattern formation. The field of optical pattern formation (OPF) studies the spatial and spatiotemporal phenomena that arise in the structure of electromagnetic field in the planes orthogonal with respect to the direction of propagation.

Experiments were designed to test the validity ofTuring's suggested pattern-forming mechanisms, which are initially capable of giving rise to only five to seven uniform structures.

Somite formation and patterning
2000As a consequence of their segmented arrangement and the diversity of their tissue derivatives, somites are key elements in the establishment of the metameric body plan in vertebrates. This article aims to largely review what is known about somite development, from the initial stages of somite formation through the process of somite regionalization ...

Reflecting pattern relationships in a pattern format
Proceedings of the 24th European Conference on Pattern Languages of Programs, 2019Patterns can be applied in isolation. However, the power of patterns lies in using them in sequences. Identifying pattern relationships with other patterns is difficult. The existing pattern formats reflect the relationships with other patterns in a very informal way.

Over the last few decades, studies of pattern formation in Drosophila imaginal discs have been proceeding along two rather separate lines. One line of research includes the studies initiated by Vogt, Bodenstein and the Hadorn group on the experimental embryology of imaginal discs, where the ability of disc fragments to grow, to regenerate, and to ...

Patterns of thylakoid system formation
Journal of Ultrastructure Research, 1979Plastid differentiation has been studied in leaves of both tobacco and wheat. We could point out a correlation between the differentiation speed of the plastids and that of the cell containing them. The ontogenetic patterns of both tobacco and wheat plastids appear to be different from the standard ones. The significance of these particular ontogeneses
