Abstract: A bot detector is disclosed. The bot detector can apply one or more subsystems for detecting bots. The subsystems may include one or more of a system for identifying self-identified bots, a system for applying one or more rules to identify bots, or a system for identifying bots based on outlier activity. The system for identifying bots based on outlier activity may include one or more outlier detection models that determine whether a user is an outlier based on features of activity data associated with a website.

Abstract: Novel genetic variants of the Fc Fragment Of Ige, High Affinity I, Receptor For; Alpha Polypeptide (FCER1A) gene are described. Various genotypes, haplotypes, and haplotype pairs that exist in the general United States population are disclosed for the FCER1A gene. Compositions and methods for haplotyping and/or genotyping the FCER1A gene in an individual are also disclosed. Polynucleotides defined by the haplotypes disclosed herein are also described.

Abstract: Polynucleotides comprising one or more of 38 novel single nucleotide polymorphisms in the human Interleukin 4 Receptor Alpha(IL4R&agr;) gene are described. Compositions and methods for detecting one or more of these polymorphisms are also disclosed. In addition, various genotypes and haplotypes for IL4R&agr; gene that exist in the population are described.
