Convergence properties of the generalized gradient projection algorithm in the presence of data perturbations are investigated. It is shown that every trajectory of the method is attracted, in a certain sense, to an "-stationary set of the problem, where " depends on the magnitude of the perturbations. Estimates for the attraction sets of the iterates are(More)
The 8890 nucleotide RNA sequence of shallot virus X (ShVX), a new virus isolated from shallot, has been determined. The sequence contains six open reading frames (ORFs) which encode putative proteins (in the 5' to 3' direction) of M(r) 194528 (ORF1), 26333 (ORF2), 11245 (ORF3), 42209 (ORF4), 28486 (ORF5) and 14741 (ORF6). The ORF1 protein was found to be(More)
DNA clones complementary to the 3'-terminal 3426 nucleotides of the genomic RNA of the carlavirus chrysanthemum virus B (CVB) have been sequenced. The sequence contains six open reading frames (ORFs) which encode putative proteins (in the 5'----3' direction) of Mr 25,749 (ORF2), Mr 11,435 (ORF3), Mr 6984 (ORF4), the triple gene block proteins, a protein Mr(More)
A number of defense polypeptides from latent seeds of weed cereal barnyard grass (Echinochloa crusgalli L.) has been isolated and characterized using an acidic extraction and high performance liquid chromatography methods in combination with MALDI-TOF mass spectrometry and Edman sequencing. Members of three antimicrobial peptide families and two protease(More)
A highly sensitive test system, based on the immuno-PCR method, was developed for the detection of two staphylococcal toxins: enterotoxin A (SEA) and toxic shock syndrome toxin (TSST). A key element of the developed systems was to obtain supramolecular complexes of bisbiotinylated oligodeoxynucleotides and streptavidin, which were to be used as DNA-tags.(More)
Optimization problems involving an infinite number of constraints are considered. This paper presents a general stochastic outer approximations method which incorporates mechanisms for active search of relevant constraints and for dropping of irrelevant constraints. The method extracts the characteristic features of several stochastic outer approximations(More)
The immuno-PCR (iPCR) method combines advantages of enzyme-linked immunosorbent assay and polymerase chain reaction, which is used in iPCR as a method of “visualization” of antigen–antibody interaction. The use of iPCR provides classical PCR sensitivity to objects traditionally detected by ELISA. This method could be very sensitive and allow for detection(More)
