Untreated trichophagia secondary to trichotillomania is a potentially life-threatening condition. Taking a thorough family and social history, most notably with the aid of a genogram or family tree, can aid in including this disorder in the differential diagnosis. This case presentation describes a unique occurrence of untreated trichotillomania in a female adolescent that led to formation of a...

Several populational networks present complex topologies when implemented in evolutionary algorithms. A common feature of these is the emergence a power law. Power law behavior with different scaling factors can also be observed genealogical networks, but we still not satisfactorily describe its dynamics or relation to population evolution over time. In this paper, use an algorithm measure impa...

In this paper we describe past experience and outline current directions in performing record linkage over large genealogical databases. 1. INTRODUCTION AND MOTIVATION Record linkage is the problem of identifying multiple records that refer to the same real-world entity. In genealogical databases, it is the problem of identifying when individuals situated in different pedigrees refer to the sam...

A genealogical species is defined as a basal group of organisms whose members are all more closely related to each other than they are to any organisms outside the group ("exclusivity"), and which contains no exclusive group within it. In practice, a pair of species is so defined when phylogenies of alleles from a sample of loci shows them to be reciprocally monophyletic at all or some specifie...

The recent genealogical history of human populations is a complex mosaic formed by individual migration, large-scale population movements, and other demographic events. Population genomics datasets can provide a window into this recent history, as rare traces of recent shared genetic ancestry are detectable due to long segments of shared genomic material. We make use of genomic data for 2,257 E...

The Arabian Horse is one of the most valued breeds in an international and historical context and has been involved in the formation of many other horse breeds. Since 2005, the Spanish Arabian Horse Breeder Association (AECCA) has developed a breeding program aimed at improving both conformation traits and endurance performance. While this selection depends on individual breeders, a population ...

Genealogy-based methods were used to estimate migration of the fungal virus Cryphonectria hypovirus 1 between vegetative compatibility types of the host fungus, Cryphonectria parasitica, as a means of estimating horizontal transmission within two host populations. Vegetative incompatibility is a self/non-self recognition system that inhibits virus transmission under laboratory conditions but it...
