Branching Processes and Evolution at the Ends of a Food Chain.
In a critically self-organized model of punctuated equilibrium, boundaries determine peculiar scaling of the size distribution of evolutionary avalanches. This is derived by an inhomogeneous generalization of standard branching processes, extending previous mean field descriptions and yielding n 1y2 together with t0 7y4, as distribution exponent of avalanches starting from species at the en...

The Polymerase Chain Reaction and Branching Processes
We construct a mathematical model for the polymerase chain reaction and its mutations using the theory of branching processes. Under this model we study the number of mutations in a randomly chosen sequence after n PCR cycles. A method for estimating the mutation is proposed and the variance of this estimator is studied. We also study the distribution of the Hamming distance between two randoml...
متن کاملDepleted Uranium in the food chain at south of Iraq
Background: Depleted Uranium (DU) is uranium with low content of U 235 produced as a result of uranium enrichment. DU has high density (19.05 g /cm3), which is 2.54 more than Iron, so it’s high penetrating power makes it preferable as emanations with high penetration power. It was used in second Gulf ware in 1991 for first time. The radioactivity of soil, plants, fruit, meat, milk and water i...
