Alternative models of subsidizing scholarly publishing and dissemination have germinated and gathered momentum in the fertile soil of dissatisfaction. Like the stubborn spring dandelion that needs but a small crack in the sidewalk to flower boldly, the first flowers of Open Access in library literature, including Biomedical Digital Libraries, have sensed their opportunity to change the existing...

Structural elements, such as stiffened panels, are designed by combining material strength data obtained from coupon tests with a failure theory for 3D stress field. Material variability is captured by dozens of coupon tests, but there remains epistemic uncertainty due to error in the failure theory, which can be reduced by element tests. Conservativeness to compensate for the uncertainty in fa...

This is a preliminary version of visual interpretation integrating multiple sensors in SUCCESSOR, an intelligent, model-based vision system. We pursue a thorough integration of hierarchical Bayesian inference with comprehensive physical representation of objects and their relations in a system for reasoning with geometry, surface materials and sensor models in machine vision. Bayesian inference...

conclusions this study provides support for the hypothesis that humans are probably infected after contact with swine sources. the findings emphasize the importance of checking the country of origin of swine and of improving sanitary control measures from the veterinary standpoint to prevent the spread of hev infection in italy. materials and methods a total of 327 hev sequences of swine and hu...

This study investigated the effects of some plant extracts on the bacterial communication system, expressed as quorum sensing (QS) activity. Quorum sensing has a directly proportional effect on the amount of certain compounds, such as pigments, produced by the bacteria. Alcohol extracts of 23 ornamental and medicinal plants were tested for anti-QS activity by the Chromobacterium violaceum assay...

Selected cultural and environmental variables were investigated for their influence on the efficacy of Phoma herbarum and Phoma exigua to cause disease on dandelion (Taraxacum officinale) under growth room conditions. In both species, mycelial fragments caused significantly greater disease severity on dandelion than spore suspensions. Mycelial age was not an important factor in disease severity...

The growth of the flowering stalk of dandelion, Taraxacuwm officiiwle, is of considerable interest because of the presence of two distinct periods of rapid growth. The last of these precedes and accompanies the maturation of the fruit, and represents a resumption of rapid growth in what would normally be considered a mature organ. MIYAKE (8, 9) showed that growth of the dandelion scape may be d...

Adaptive testing is impractical in real world situations where many diierent learner traits need to be measured in a single test. Recent student modelling approaches have attempted to solve this problem using diierent course representations along with sound knowledge propagation schemes. This paper shows that these diierent representations can be merged together and realized in a granularity hi...
