Recent compressed suffix trees targeted to highly repetitive sequence collections reach excellent compression performance, but operation times are very high. We design a new suffix tree representation for this scenario that still achieves very low space usage, only slightly larger than the best previous one, but supports the operations orders of magnitude faster. Our suffix tree is still orders...

A library of cloned cDNAs representative of lymphocyte total poly(A)+ RNA was screened with total DNA probes at high clone density. 10% of the recombinants showed the presence of sequences which are repeated in the genome. Further analysis of six such isolated cDNA clones indicated that they contain different families of repetitive sequences with reiteration frequencies of between 150 and 45,00...

To salvage marine ecosystems from fishery overexploitation, sustainable and efficient aquaculture must be emphasized. The knowledge obtained available genome sequence of organisms has accelerated in many cases. black tiger shrimp (Penaeus monodon) is one the most prominent cultured penaeid shrimps (Crustacean) with an average annual global production half a million tons last decade. However, it...

Central programming deficits in Parkinson's disease (PD) were studied in two reaction time (RT) experiments. In Experiment 1, PD patients and controls performed sequences of hand postures that varied in length, the number of different postures (repetitive vs heterogeneous), and the delay interval before movement. Before movement, the PD group planned repetitive movements like controls whereas f...
