When employing a similarity function to measure the similarity between two cases, one large problem is how to determine the feature weights. This paper presents a new method for learning feature weights in a similarity function from the given similarity information. The similarity information can be divided into two kinds: One is called qualitative similarity information which represents the si...

Information about similarities and differences in the demographic history of host and parasite populations is potentially useful for making inferences about a variety of evolutionary processes. However, it is difficult to observe the historical demographic properties of natural populations directly. Here, the extent of demographic similarity in a host and its parasite was examined indirectly by...

High novelty seeking is a complex personality attribute correlated with risk for substance abuse. There are many putative mouse models of some aspects of novelty seeking, but little is known of genetic similarities among these models. To assess the genetic coherence of "novelty seeking," we compared the performance of 14 inbred strains of mice in five tests: activity in a novel environment, nov...

Essential hypertension (EH) accounts for 80-90% of hypertension, and pregnancy-induced hypertension (PIH) is responsible for hypertension during pregnancy. Both considered multifactorial disorders. While both have many features in common, conditions and causes of these diseases have yet to be clarified. Since both diseases are associated with hypertension, the genetic backgrounds may contain co...

Subspecies are commonly used taxonomic units to formally describe intraspecific geographic variation in morphological traits. However, the concept of subspecies is not clearly defined, and there is little agreement about what they represent in terms of evolutionary units, and whether they can be used as reliably useful units in conservation, evolutionary theory and taxonomy. We here investigate...

objectives: it has been noted that stuttering is more prevalent in bilinguals than in monolinguals. the similarities of the languages involved have been mentioned to justify the difference between stuttering prevalence among bilingual and monolingual speakers. the aim of this study is to investigate the effect of language similarities on prevalence of stuttering among kurdish-farsi bilingual st...
