Catalytic and Mutually Catalytic Branching
In this paper we present an overview of recent work on lattice and measure-valued models of catalytic reactions and in particular catalytic branching systems. The main phenomena exhibited by nearly critical branching systems are dimension-dependent clumping in small and large space and time scales. Special emphasis is given to the e ects which occur when the catalyst is highly clumped and in pa...

متن کاملMultivesicular bodies
theoreticians in developmental biology, as mainstream opinion held that one had to clone the genes involved and isolate the corresponding molecules — and that development would then be understood. The interest in theories was correspondingly low. At this time, the fascinating and beautiful patterns on shells were for me an inspiring looking glass to study the richness of patterns that can emerg...
متن کاملCajal bodies
What are they? Cajal bodies are nuclear suborganelles, typically 0.5 μm in diameter, discovered in 1903 by Santiago Ramón y Cajal. They are dynamic structures involved in the biogenesis of small ribonucleoproteins (RNPs). Cajal bodies contain the highest concentration of small RNPs in the nucleoplasm, as well as a host of other protein factors involved in diverse processes. They are not major s...
متن کاملIsoradial Bodies
In this paper, we show that for any dimension d ≥ 2 there exists a non-spherical strongly isoradial body i.e., a non-spherical body of constant breadth, such that its orthogonal projections on any subspace has constant inand circumradius. Besides the curiosity aspect of these bodies, they are highly relevant for the analysis of geometric inequalities between the radii and their extreme cases.
