    Decision Making for Inconsistent Expert Judgments Using Negative Probabilities

    Full text link
    In this paper we provide a simple random-variable example of inconsistent information, and analyze it using three different approaches: Bayesian, quantum-like, and negative probabilities. We then show that, at least for this particular example, both the Bayesian and the quantum-like approaches have less normative power than the negative probabilities one.Comment: 14 pages, revised version to appear in the Proceedings of the QI2013 (Quantum Interactions) conferenc

    Parkia gigantocarpa Ducke, conhecida popularmente como Fava- Atanã é uma espécie de grande porte, que pode ser utilizada para produção de celulose, recomposição de áreas degradadas e construção em geral. O objetivo desse estudo foi verificar a influência de diferentes substratos e temperaturas sobre a germinação de sementes de P. gigantocarpa. Realizou-se um experimento inteiramente casualizado em esquema fatorial 5 x 5, com 4 repetições de 25 sementes, por um período de 12 dias. Foram utilizados diferentes substratos (rolo de papel, areia, areia + serragem (1:1), vermiculita e fibra de coco triturada) em função de diferentes temperaturas constantes (15, 20, 25, 30 e 35ºC). Nas temperaturas de 15 e 20ºC houve inibição no desenvolvimento normal das plântulas, ocorrendo germinação de plântulas normais somente nas temperaturas de 25, 30 e 35°C. No geral, a temperatura de 30°C foi a mais favorável para a germinação das sementes de P. gigantocarpa, tendo como melhores substratos a areia, areia + serragem (1:1) e fibra de coco

    Use of the random amplified polymorphic DNA technique to characterize soybean (Glycine max (L.) Merrill) genotypes.

    We have started a breeding program to genetically eliminate. the lipoxygenase isozymes (LOX) from soybean seeds. These enzymes are believed to be lhe main cause of off-flavors in soybean products. LOX are present in the seed as three isozymes encoded by Ihree different genes, which are inherited in a simple mendelian fashion. Mutants lacking each one of these isozymes have been identified in the world gennplasm. To introduce Ihese null ali eles into lhe Brazilian variety Cristalina, three mutant progenitors were chosen PI 408.251 (LOX 1 minus), PI 86.023 (LOX2 minus), and Ichigowase (LOX3 minus). The random amplified polymorphic DNA (RAPD) technique was used to characterize these progenitors, as well as lines lacking LOXI (CRI), LOX3 (CR3), LOXI and 3 (CRI,3), and LOX2 and 3 (UFV 91-263, UFV91-401 and UFV 91-717). The results enabled us to establish lhe fmgerprint of each genotype and the genetic distances among them

    The Rarita-Schwinger Particles Under de Influence of Strong Magnetic Fields

    In this work, we calculate the solutions of the Rarita-Schwinger equation with the inclusion of the eletromagnetic interaction. Our gauge and coupling prescription choices lead to Dirac-type solutions. One of the consequences of our results are the Landau level occupation of particles, quite different from the usual spin 1/2 particle system occupation numbers.Comment: 12 page
