Mobile agent systems incur resource overheads as they acquire and maintain knowledge about their network environment. This paper presents a technique that, for a speci c set of cases, optimises network resource consumption through dynamic selection of agent interaction protocols. This process is made possible through learning on the part of static knowledge agents, which can then predict the li...

Although most people believe that planners that delay step-ordering decisions as long as possible are more eecient than those that manipulate totally ordered sequences of actions, this intuition has received little formal justii-cation or empirical validation. In this paper we do both, characterizing the types of domains that ooer performance diierentiation and the features that distinguish the...

The comparative analysis effectiveness according to country origin institution shows that ...

me to coordinate a review series on adult immuno-defi ciency, I voluntarily agreed and suggested 10 topics. Th e editors selected six with the greatest importance for rheumatologists. Th e authors of the six articles all come from research groups with outstanding track-records in their respective fi elds. Why present adult-onset immunodefi ciency to a readership of rheumatologists? Th e answer ...

With the advent of large submillimeter telescopes at high, dry sites, the atmospheric background noise in a moderate bandwidth can be low enough to challenge the ability of instrument designers to produce su ciently low noise bolometers to be background limited. We compare the predictions for the noise power of a bolometer observing through an emissive atmosphere, considering the e ect of atmos...

In this paper, we demonstrate the effi ciency of seller entry in a model of competing auctions in which we allow for both buyer and seller heterogeneity. This generalizes existing effi ciency results in the competitive search literature by simultaneously allowing for nonrival (many-on-one) meetings and private information. ∗We thank Andrzej Skrzypacz, our editor, and Jeremy Bulow for their help...

Sir, Common variable immunode¢ciency (CVID), one of the most frequent of the primary speci¢c immunode¢ciencies, is a heterogeneous group of syndromes characterized by a de¢ciency in antibody synthesis associated with panhypogammaglobulinaemia and recurrent bacterial infections (1). The occurrence of non-caseating granulomas in di¡erent organs, including the skin, has been described previously. ...

Introduction . Over the past decade, incidence of iron deficiency anemia has increased. According to World Health Organization (WHO), it occurs in every 3 people world. Most often, developing countries and is mainly affected by 2 groups population — young children pregnant women. In pediatric practice, there are single works devoted problem comorbidity, connection with which our studies particu...
