Un alieno sta visitando la Terra attraverso una proiezione astrale quando involontariamente assiste a un omicidio. Ora deve affrontare due problemi: deve riferire il crimini alle autorita? E se si, in che modo?
Wesley Stoneham, un avvocato e un politico molto ambizioso, ha appena ucciso sua moglie in un impeto di rabbia. Ora sta pianificando di incolpare un innocente ma non sa che c'e stato un testimone dell'omicidio: un alieno invisibile che, attraverso una proiezione astrale sta visitando la Terra. ORa l'alieno ha due problemi; deve riferire il crimine alle autorita? e se si, come?

Discrete Time Branching Processes in Random Environment
Автор: Gotz Kersting
Год издания:
Branching processes are stochastic processes which represent the reproduction of particles, such as individuals within a population, and thereby model demographic stochasticity. In branching processes in random environment (BPREs), additional environmental stochasticity is incorporated, meaning that the conditions of reproduction may vary in a random fashion from one generation to the next. This book offers an introduction to the basics of BPREs and then presents the cases of critical and subcritical processes in detail, the latter dividing into weakly, intermediate, and strongly subcritical regimes.
Controlled Branching Processes
Автор: George Petrov Yanev
Год издания:
The purpose of this book is to provide a comprehensive discussion of the available results for discrete time branching processes with random control functions. The independence of individuals’ reproduction is a fundamental assumption in the classical branching processes. Alternatively, the controlled branching processes (CBPs) allow the number of reproductive individuals in one generation to decrease or increase depending on the size of the previous generation. Generating a wide range of behaviors, the CBPs have been successfully used as modeling tools in diverse areas of applications.
