Abstract: In a method for recovering a partition using backup boot record information, an unallocated area is separated from a disk or an evidence image. The unallocated area is searched for a location of a backup boot record. Whether is backup boot record of a file system to be detected is present in found sectors is analyzed. If the backup boot record is found to be the backup boot record of the file system desired to be detected as a result of the analysis, it is verified whether the backup boot record is a boot record of a valid partition. If it is verified that the backup boot record is the boot record of the valid partition, a file system of a deleted partition is parsed using the backup boot record and a deleted directory or file is recovered.

Abstract: A method for the quantification of equivalence between mutational phenotypes to develop non-obvious human disease models is described herein. The present inventors discover candidate genes for diseases of interest by: first, identifying orthologous phenotypes (called phenologs) involving the phenotype of interest (the first phenotype), in which a set of genes is associated with the first phenotype in the first organism, a set of genes is associated with a second phenotype in a second organism, the first and second phenotypes not having one or more common characteristics, and the second phenotype is selected such that at least one gene belongs to both the first and second phenotype gene sets; second, selecting from the second organism one or more second phenotype genes, other than the genes known to overlap the first and second phenotypes, as candidates for also belonging to the first phenotype in the first organism.
