Excretory-secretory products (ESP) of myiasis producing agents are involved in nutrition and development of larvae and are often immunogens. This study was carried out in order to define the antigenicity, the immunogenicity of Oestrus ovis ESP and the role of sheep immune response to ESP. Twenty-four six to eight month old female lambs were randomly allocated into two groups. The first one was ...

A 68-kilodalton (kd) outer membrane protein antigen of Bordetella bronchiseptica has been identified by using monoclonal antibodies that recognized two nonoverlapping determinants. Antibody BB05 also reacted with homologous proteins from Bordetella pertussis and Bordetella parapertussis but not with another 12 organisms from various bacterial genera. Passive injection of BB05 antibody protected...

The crystal delta-endotoxin of Bacillus thuringiensis subsp. israelensis is less toxic to larvae of Anopheles freeborni than to larvae of Aedes aegypti. However, when solubilized crystal was used, larvae from both species showed similar sensitivities. This effect presumably was due to the differences in feeding behavior between the two mosquito larvae when crystal preparations are used. A proce...

The original model of P systems with symbol objects introduced by Păun was shown to be computationally universal, provided that catalysts and priorities of rules are used. By reduction via register machines Sosík and Freund proved that the priorities may be omitted from the model without loss of computational power. Freund, Oswald, and Sosík considered several variants of P systems with catalys...

We describe several improvements to Freund and Schapire's AdaBoost boosting algorithm, particularly in a setting in which hypotheses may assign confidences to each of their predictions. We give a simplified analysis of AdaBoost in this setting, and we show how this analysis can be used to find improved parameter settings as well as a refined criterion for training weak hypotheses. We give a spe...

Many applications require the solution of multiple linear systems that have the same coeecient matrix, but diier in their right-hand sides. Instead of applying an iterative method to each of these systems individually, it is more eecient to employ a block version of the method that generates iterates for all the systems simultaneously. In this paper, we propose a block version of Freund and Nac...

Three AdaBoost variants are distinguished based on the strategies applied to update the weights for each new ensemble member. The classic AdaBoost due to Freund and Schapire only decreases the weights of the correctly classified objects and is conservative in this sense. All the weights are then updated through a normalization step. Other AdaBoost variants in the literature update all the weigh...

Immunization of rabbits and rhesus monkeys with Streptococcus mutans whole cells, cell walls, and defined streptococcal antigens (SAs) SA I/II, SA I, and SA II resulted in high antibody titers to SA I/II (10(-4) to 10(-6)) when tested by the solid-phase radioimmunoassay. Cross-reactive antibodies to heart homogenates (HH) were not elicited in rhesus monkeys. A few rabbits immunized with cell wa...

Insbesondere Social Media Plattformen arbeiten in ihren diversen Anwendungsoptionen mit Konzepten des kollektiv und algorithmisch hergestellten Optimums permanenten, potentiellen Verbesserung. Die Optimierungsappelle sind strukturell dezentral gesteuerte Prozesse eingelagert erzeugen spezifische Affizierungsrelationen Selbstbezügl...

A synthetic peptide whose sequence was derived from the circumsporozoite protein of Plasmodium knowlesi coupled to bovine gamma globulin has been shown to be immunogenic when administered with Freund complete adjuvant. The present experiments were designed to test the immunogenicity of the peptide when attached to a tetanus toxoid carrier and administered with alum or murabutide, both acceptabl...
