Detecting Undetectable Computer Viruses
Signature-based detection relies on patterns present in viruses and provides a relatively simple and efficient method for detecting known viruses. At present, most anti-virus systems rely primarily on signature detection. Metamorphic viruses are one of the most difficult types of viruses to detect. Such viruses change their internal structure, which provides an effective means of evading signat...

متن کاملDetecting the undetectable: uncovering duplicated segments in Arabidopsis by comparison with rice.
Genome analysis shows that large-scale gene duplications have occurred in fungi, animals and plants, creating genomic regions that show similarity in gene content and order. However, the high frequency of gene loss reduces colinearity resulting in duplicated regions that, in the extreme, no longer share homologous genes. Here, we show that by comparison with an appropriate second genome, such p...
متن کاملOn the frequency of undetectable recombination events.
Simple analytical results show that many recombination events occur in such a way as to have no effect on the resultant DNA sequence. The proportion of these undetectable events depends on the population size, mutation rate and recombination rate and is quite large for reasonable values of these quantities. Efforts to estimate recombination rates and frequencies directly from DNA sequence data ...
متن کاملWhen prostate cancer remains undetectable: The dilemma.
Since the first report on the efficacy of sextant biopsy under transrectal ultrasound guidance, there have been many modifications related to the total number of cores and the localization of biopsies to improve the prostate cancer (PCa) detection rate. The 2010 National Comprehensive Cancer Network Early PCa Detection Guidelines noted the 12-core biopsy scheme as the standard. However, this ex...
