The beauty of plants has attracted the attention of mathematicians for Mathematics centuries.
Conspicuous geometric features such as the bilateral sym and beauty metry of leaves, the …

A theory is proposed for the development of filamentous organisms, based on the assumptions
that the filaments are composed of cells which undergo changes of state under inputs …

Sixty vascular tumors including 23 angiosarcomas, 300 nonvascular tumors, and selected
normal tissues were immunohistochemically evaluated with antibodies to CD31, CD34, and …

In this paper we present a method for modeling herbaceous plants, suitable for generating
realistic plant images and animating developmental processes. The idea is to achieve realism …

Formal systems are proposed and constructed to generate cellular arrays corresponding to
developmental stages of some simple organisms: lower plants, snail embryos and leaves. …

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease of variable
severity. Progressive muscle wasting and impairment in functional ability in SMA have a …

Multicellular organisms are construed as arrays of symbols, each symbol standing for a cell.
Their development is modelled by algorithmic rules which provide the allowed substitutions …

Developmental systems were introduced (Lindenmayer, 1968, 1971) in order to model
morphogenetic (pattern-generating) processes in growing, multicellular, filamentous organisms. …

L-systems (1, 2, 3)* were introduced by one of us in order to model morphogenetic processes
in growing multicellular filamentous organisms. We will show here, how a computer model …
