This article, based on historical and anthropological sources, ethnographic materials, highlights the issues of understanding genealogical identity associated with genealogies preserved by Uzbeks their kinship system. Various groups Uzbeks, ethnocultural structures such as clans (generation, clan) processes manifestation a single cultural unit in same space time are analyzed.

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

Despite the increasing popularity of multilocus sequence typing (MLST), the most appropriate method for characterizing bacterial variation and facilitating epidemiological investigations remains a matter of debate. Here, we propose that different typing schemes should be compared on the basis of their power to infer clonal relationships and investigate the utility of sequence data for genealogi...

Classical ancestor trees, descendant trees, Hourglass charts, and their visual variants such as node-link diagrams or fan charts are suitable for assessment of people’s relationships when one is focused on a particular person (the so-called main person) and his/her direct ancestors and descendants. Such tree-based representations miss a broader context of relationships and do not allow quick as...

In this communication a representation of the links between DNA-relatives based on Graph Theory is applied to the analysis of personal genomic data to obtain genealogical information. The method is tested on both simulated and real data and its applicability to the field of genealogical research is discussed. We envisage the proposed approach as a valid tool for a streamlined application to the...

MICROBIAL EVOLUTION: A GENEALOGICAL PERSPECTIVE Protists, bacteria and archaea (the prokaryotes), and their mobile genetic elements populate the microbial world. This world is ancient (several billion years old), numerically huge (with 5 × 1030 prokaryotic cells and 10–100 times more viruses!), and genetically extremely diversified. Such a large assemblage cannot be ignored in attempts to under...

This paper presents a challenging Family History Knowledge Base (FHKB) authored in OWL 2 DL. Originally, the FHKB was designed to act as a tool for education, especially about OWL 2’s features and the use of automated reasoners. As a result, the FHKB has been constructed to maximise use of inference. For individuals representing people, only genealogical assertions on parentage and sparse asser...

Last year marked the 10th anniversary of the birth of phylogeography as a formal discipline. However, the field’s gestation began in the mid-1970s with the introduction of mitochondrial (mt) DNA analyses to population genetics, and to the profound shift toward genealogical thought at the intraspecific level (now formalized as coalescent theory) that these methods prompted. This paper traces the...
