Inheritance, contact, convergence

Exponential Convergence for One Dimensional Contact Processes * )

The complete convergence theorem implies that starting from any initial distribution the one dimensional contact process converges to a limit as t--,-oo. In this paper we give a necessary and sufficient condition on the initial distribution for the convergence to occur with exponential rapidity.

Mitochondrial DNA Mutations, Pathogenicity and Inheritance

Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...

Organelle Inheritance

The need to inherit those membranes that arise from the ER is much less clear. As an example, the integral *Imperial Cancer Research Fund Cell Biology Laboratory membrane proteins and lipids of the Golgi apparatus are derived entirely from the ER. If a daughter did not 44 Lincoln's Inn Fields London WC2A 3PX inherit a copy of the Golgi apparatus, it should be able to synthesize one de novo. Sev...

Systemic Inheritance

In this paper we face the problem of providing a common representation for knowledge learnt from examples and some kind of background knowledge about a given framework. To this end we postulate inheritance hierarchies endowed with some retrieval rules in addition to the inheritance operation. This hierarchies can be algorithmicaly built according to the specifications encoded in our input data....
