The invention is directed to methods of generating sequence profiles of populations of nucleic acids, whose member nucleic acids contain regions of high variability, such as populations of nucleic acids encoding T cell receptors or B cell receptors. In one aspect, the invention provides pluralities of sets of primers for generating nested sets of templates from nucleic acids in such populations, thereby insuring the production of at least one template from which sequence reads are generated, despite such variability, or dispite limited lenghs or quality of sequence reads. In another aspect, members of such populations are bidirectionally sequenced so that further sequence information is obtained by analyzing overlapping sequence reads in the zones of highest variability.

A system, method and program product for evaluating search algorithms. A method is provided that includes: defining a population of searches and database records from a search history database; applying a sampling method and direct sampling rates to each search/record pair in the population using a computing system, wherein search/record pairs having a higher variability relative to the population are assigned a relatively higher probability; randomly sampling a direct sample of search/record pairs with the computing system using the direct sampling rates to increase a likelihood of obtaining search/record pairs having the higher variability; running a search algorithm and measuring errors for the direct sample and/or for an associated indirect sample; and calculating an estimated error rate for the search algorithm using inverse probability weighting.

A method for forecasting a future inventory demand includes receiving historical demand data associated with a part number and statistically analyzing the historical demand data associated with one or more part numbers to identify each part number as one of a seasonal part number, a quasi-seasonal part number, a high variability part number, or a non-seasonal part number. If the part number is identified as a seasonal part number, a first inventory requirement for a first predetermined portion of a future demand period is estimated. If the part number is identified as a quasi-seasonal part number, a second inventory requirement for a second predetermined portion of a future demand period is estimated, wherein the second predetermined portion of the future demand period is a multiple of the first predetermined portion. If the part number is identified as a high variability part number, a third inventory requirement for a third predetermined portion of a future demand period is estimated.

The invention provides a mitochondrial gene sequence for identifying authenticity and quality of Cordyceps sinensis and an operation method thereof. According to the method, differences of mitochondrial genes between ghostmoth and other lepidopteran insects are compared and thus high-variability areas can be searched. Specific primers of the ghostmoth are designed to obtain sequences of corresponding sections of mitochondria of host insects; if a nucleotide difference rate is less than 1-1.5 %, the insects are determined to be a same species but different individuals, and if the nucleotide difference rate is more than 6 %, the insects are determined to be a same genus but different species, thereby not only identifying whether to-be-detected samples are the Cordyceps sinensis formed with Hepialus larvae as the host insects, but also determining producing areas of the to-be-detected samples, and thus determining the authenticity and grades of the to-be-detected samples The method is simple in steps, easy to operate, and few in sample amount, and can minimize sample loss. According three pairs of the specific primers provided by the invention, the authenticity and the grades of the samples can be rapidly and conveniently detected through detecting whether the samples have same or similar nucleotide sequences as well as similarity of the nucleotide sequences.
