Abstract The truncation equation for the derivative nonlinear Schrdinger equation has been discussed in this paper. The existence of a special heteroclinic orbit has been found by using geometrical singular perturbation theory together with Melnikovs technique.
Query-by-keywords is the most popular manner to search for data in this computing age. However, most work was proposed for searching centralized relational databases. This paper investigates how keyword search is to be deployed in relational database-enabled peer-to-peer systems. Unlike centralized system, the key challenges in this new computing paradigm come from the autonomy of peers, the lack...
Three synthetic cyclic tripeptides, each containing a γ-glutamyl residue were shown to induce the production of interleukin-1 (IL-1) from human peripheral blood mononuclear cells (PBMC). In addition, the cyclic peptide cyclo[Glu(Lys-β-Ala-)-OH] (cG-2) was capable of eliciting IL-1 production from PBMC dose-dependently.
