The Zero Curvature Formulation of TB, sTB Hierarchy and Topological Algebras
A particular dispersive generalization of long water wave equation in 1 + 1 dimensions, which is important in the study of matrix models without scaling limit, known as two–Boson (TB) equation, as well as the associated hierarchy has been derived from the zero curvature condition on the gauge group SL(2, R) ⊗ U(1). The supersymmetric extension of the two–Boson (sTB) hierarchy has similarly been...

متن کاملSTB-tree: A Self-Tunable Spatio-Temporal B-tree Index for Moving Objects
In a moving objects database (MOD) the dataset and the workload change frequently. As the locations of objects change in space and time, the data distribution also changes and the answer for a same query over the same region may vary widely over time. As a result, traditional static indexes are not able to perform well and it is critical to develop selftuning indexes that can be reconfigured au...
متن کاملEscherichia coli heat-stable enterotoxin b (STb) in vivo internalization within rat intestinal epithelial cells.
Heat-stable enterotoxin b (STb) is a low molecular weight toxin known to bind sulfatide, its receptor. The fate of STb bound to rat intestinal epithelium cells was followed using an anti-toxin gold labeled assay and transmission electron microscopy. The data suggest that STb toxin and the fusion protein maltose binding protein (MBP)-STb were internalized whereas its mutant I41 E-M42R with reduc...
متن کاملCharacterization of Escherichia coli strains producing heat-stable enterotoxin b (STb) isolated from humans with diarrhea.
Two of 49 cytolethal distending toxin-producing strains of Escherichia coli isolated from human stools contained the gene coding for heat-stable enterotoxin b (STb), as detected by a colony hybridization assay. The STb gene was found to be on a 70-kb plasmid also coding for heat-labile enterotoxin (pLT-I). Restriction endonuclease analysis showed the STb gene from human isolates to be similar t...
