Sexually transmitted diseases (STDs), including urethritis caused by gonococcus and Chlamydia trachomatis, are of increasing public health importance (1, 3, 6, 7, 9). The common occurrence of coinfections and the emergence of antimicrobial resistance of both pathogens emphasize the need for a single broadly active drug for management of these STDs (2, 3, 7, 9, 11–13). Penicillins and other beta...

Genetic Algorithm Combining Operation Tree (GAOT) was constructed to estimate the slump flow of high-performance concrete (HPC) by using seven concrete ingredients. HPC is a highly complex material; because modeling its behavior is extremely difficult, robust optimization techniques are required. GAOT is a type of evolutionary algorithm that simultaneously optimizes functions and their associat...

Four neurotoxins that activate the action potential Na+ ionophore of electrically excitable neuroblastoma cells interact with two distinct classes of sites, one specific for the alkaloids veratridine, batrachotoxin, and aconitine, and the second specific for scorpion toxin. Positive heterotropic cooperativity is observed between toxins bound at these two classes of sites. Tetrodotoxin is a nonc...

Abstract argumentation frameworks have received a lot of interest in recent years. Most computational problems in this area are intractable but several tractable fragments have been identified. In particular, Dunne showed that many problems can be solved in linear time for argumentation frameworks of bounded tree-width. However, these tractability results, which were obtained via Courcelle’s Th...

operated applicator and incorporated Waudo, S. W., and Norton, D. C. 1986. Pathogenic effects of Pratylenchus scribneri in maize into the top 4 cm of soil. Soil samples inbreds and related cultivars. Plant Disease 70:636-638. were taken from the top 25 cm of soil with a 2-cm-diameter soil probe at planting Maize inbreds C123Ht, C103, and Mol7Ht inoculated with 8,500 ± 500 Pratylenchus scribneri...
