Method for detecting and identifying unknown bioagents, including bacteria, viruses and the like, by a combination of nucleic acid amplification and molecular weight determination using primers which hybridize to conserved sequence regions of nucleic acids derived from a bioagent and which bracket variable sequence regions that uniquely identify the bioagent. The result is a “base composition signature” (BCS) which is then matched against a database of base composition signatures, by which the bioagent is identified.

In a nonvolatile memory system that includes a block-erasable memory array, records are individually maintained for certain classifications of blocks. One or more lists may be maintained for the blocks, an individual list ordered according to a descriptor value. Such ordered lists allow rapid identification of a block by descriptor value.

The present invention relates to systems and methods capable of characterizing populations of organisms within a sample. The characterization may utilize probabilistic matching of short strings of sequencing information to identify genomes from a reference genomic database to which the short strings belong. The characterization may include identification of the microbial community of the sample to the species and / or sub-species and / or strain level with their relative concentrations or abundance. In addition, the system and methods may enable rapid identification of organisms including both pathogens and commensals in clinical samples, and the identification may be achieved by a comparison of many (e.g., hundreds to millions) metagenomic fragments, which have been captured from a sample and sequenced, to many (e.g., millions or billions) of archived sequence information of genomes (i.e., reference genomic databases).

An innovative optical system and method is disclosed for analyzing and uniquely identifying high-order refractive indices samples in a diverse population of nearly identical samples. The system and method are particularly suitable for ultra-fine materials having similar color, shape and features which are difficult to identify through conventional chemical, physical, electrical or optical methods due to a lack of distinguishing features. The invention discloses a uniquely configured optical system which employs polarized sample light passing through a full wave compensation plate, a linear polarizer analyzer and a quarter wave retardation plate for producing vivid color bi-refringence pattern images which uniquely identify high-order refractive indices samples in a diverse population of nearly visually identical samples. The resultant patterns display very subtle differences between species which are frequently indiscernable by conventional microscopy methods. When these images are analyzed with a trainable with a statistical learning model, such as a soft-margin support vector machine with a Gaussian RBF kernel, good discrimination is obtained on a feature set extracted from Gabor wavelet transforms and color distribution angles of each image. By constraining the Gabor center frequencies to be low, the resulting system can attain classification accuracy in excess of 90% for vertically oriented images, and in excess of 80% for randomly oriented images.

Alternatively spliced RNA, along with their normally-spliced counterparts, can be rapidly identified by hybridizing cDNA from normal tissue to cDNA from an abnormal or test tissue. The two cDNA populations are separately tagged prior to hybridization, which allows isolation of double-stranded cDNA containing both normal and alternatively spliced molecules. Within this population, pairing of cDNA molecules representing an alternatively spliced mRNA with cDNA molecules representing the counterpart normally spliced mRNA will form double-stranded cDNA with single-stranded mismatched regions. The mismatched double-stranded cDNA are isolated with reagents that bind single-stranded nucleic acids. The strands of each mismatched double-stranded cDNA are then coupled and analyzed, simultaneously identifying both normal and alternatively spliced molecules.
