An effective method based on the combination of solid phase extraction and gel chromatography to extract and purify microcystin-RR (MC-RR) from natural cyanobacteria bloom was developed. Thirty five gram natural cyanobacterial bloom scum was extracted with 70% aqueous methanol. After the methanol in the crude extract was removed by a rotary evaporator, the solid phase extraction was used for pr...

Surgical phase recognition is of particular interest to computer assisted surgery systems, in which the goal predict what occurring at each frame for a video. Networks with multi-stage architecture have been widely applied many vision tasks rich patterns, where predictor stage first outputs initial predictions and an additional refinement operates on perform further refinement. Existing works s...

A Bloom filter is a simple space-efficient randomized data structure for representing a set in order to support membership queries. Bloom filters allow false positives but the space savings often outweigh this drawback when the probability of an error is controlled. Bloom filters have been used in database applications since the 1970s, but only in recent years have they become popular in the ne...

Bloom Filters are widely used in many applications including database management systems. With a certain allowable error rate, this data structure provides an efficient solution for membership queries. The error rate is inversely proportional to the size of the Bloom filter. Currently, Bloom filters are stored in main memory because the low locality of operations makes them impractical on secon...

Privacy-preserving record linkage with Bloom filters has become increasingly popular in medical applications, since Bloom filters allow for probabilistic linkage of sensitive personal data. However, since evidence indicates that Bloom filters lack sufficiently high security where strong security guarantees are required, several suggestions for their improvement have been made in literature. One...

Samples of natural phytoplankton assemblages were taken on 4 occasions between 28 March and 19 April 1990 at 2 stations located to the southwest of Plymouth (UK) and incubated in experimental microcosms under constant light and temperature. 14C incorporation into cell constituents [proteins, polysaccharides, lipids and low molecular weight metabolites (LMWM)] and the biochemical compos~tion of ...

Sporadic algal bloom development within a 10 year monitoring program in Virginia tidal tributaries of Chesapeake Bay is reviewed. These blooms were common events, characteristically producing a color signature to the surface water, typically short lived, occurring mainly from spring into autumn throughout different salinity regions of these rivers, and were produced primarily by dinoflagellates...

background: cutaneous reactions like pruritus and erythema are common in warm months of the year in bushehr port, persian gulf, iran due to jellyfish envenomation. this study reports isolation of the chrysaora hysoscella nematocysts and evaluating its pharmacological activities during a bloom in 2013. methods: the venom of c. hysoscella captured in jofre area in bushehr port was analyzed. the e...

DNA, as all molecules in the cell, is constantly agitated through thermal energy and bombardment from water and neighboring masses. Through super-resolution tracking of DNA in live cells and simulation of the statistical mechanics of polymers we are building intuition into the function of DNA loops. We have discovered that the normal kinetics of replication fork progression allows time for ther...
