This paper presents an algorithm for exact pattern matching based on a new type of Bloom filter that we call a feed-forward Bloom filter. Besides filtering the input corpus, a feed-forward Bloom filter is also able to reduce the set of patterns needed for the exact matching phase. We show that this technique, along with a CPU architecture aware design of the Bloom filter, can provide speedups b...

The onset of phytoplankton blooms in late winter, early spring has been traditionally associated with the shoaling of the mixed layer above a critical depth. Here we show that the onset of a bloom can also be triggered by a reduction in air-sea fluxes at the end of winter. When net cooling subsides at the end of winter, turbulent mixing becomes weak, thereby increasing the residence time of phy...

BLOOM is a system for doing software understanding through visualization. Software understanding involves asking specific questions about the structure and behavior of a software system and getting accurate answers quickly. BLOOM addresses software understanding by providing a complete system that combines facilities for collecting and analyzing program data, a visual language for defining what...

The fate of diazotrophic nitrogen (N(D)) fixed by planktonic cyanobacteria in pelagic food webs remains unresolved, particularly for toxic cyanophytes that are selectively avoided by most herbivorous zooplankton. Current theory suggests that N(D) fixed during cyanobacterial blooms can enter planktonic food webs contemporaneously with peak bloom biomass via direct grazing of zooplankton on cyano...

The study was conducted to elucidate the possibility that a shift in color preferences of adults of the apple blossom beetle, Epicometis hirta, occurs sometime after the end of overwintering and the onset blooming of Prunus spp. trees and between the termination of blooming and the death of the adults. Such information is needed to choose the best color of the traps used for the detection, moni...

Research and optimization of the Bloom filter algorithm in Hadoop An increasing number of enterprises have the need of transferring data from a traditional database to a cloud-computing system. Big data in Teradata (a data warehouse) often needs to be transferred to Hadoop, a distributed system, for further computing and analysis. However, if data stored in Teradata is not synced with Hadoop, e...

The Werner and Bloom syndromes are caused by loss-of-function mutations in WRN and BLM, respectively, which encode the RecQ family DNA helicases WRN and BLM, respectively. Persons with Werner syndrome displays premature aging of the skin, vasculature, reproductive system, and bone, and those with Bloom syndrome display more limited features of aging, including premature menopause; both syndrome...

The surface composition, in terms of sugar and fat content, on untempered and overtempered chocolates was estimated by carefully scraping the surface layer and analyzing fat and sugar melting enthalpies by differential scanning calorimetry. The dull surface of over-tempered chocolate had a fat and sugar composition similar to the initial chocolate mass, whereas the surface bloom formed on untem...
