The temperature-sensitive gametogenesis-defective mutant, gam-1 is sex-limited, expressed only in mating type minus (mt-), and can sexually agglutinate but not fuse at the restrictive temperature (35 degrees C) with gametes of wild type (wt) mt+. Thin-section, freeze-cleave, and scanning electron microscopy reveal that the gam-1 phenotype is dependent on both the temperature at which the cells ...

Geodesic acoustic mode(GAM) driven by energetic particles are observed in the Large Helical Device by a heavy ion beam probe. The GAM frequency shifts upward in plasmas with monotonic magnetic shear. In plasmas with reversed magnetic shear, on the other hand, the observed GAM and the energetic-particle induced mode, which is probably reversed-shear induced Alfvén Eigenmode(RSAE), appears, and t...

We report purification of an 18-kDa heparin-binding growth factor secreted from human cancer cells which is homologous to a developmentally regulated, neurotrophic factor, heparin-binding growth-associated molecule/pleiotrophin (HB-GAM/PTN; Merenmies, J., and Rauvala, H. (1990) J. Biol. Chem. 265, 16721-16724; Li, Y. S., Milner, P. G., Chauhan, A. K., Watson, M. A., Hoffman, R. M., Kodner, C. M...

The energetic-particle driven geodesic acoustic mode (GAM) has been identified on the basis of the spatial structures and frequency measured by heavy ion beam probe (HIBP) and Mirnov coil array. The frequency of the mode is higher than the GAM frequency estimated using parameters of bulk plasmas, and the high frequency GAM can be derived by taking into account the energy distribution function o...

In this paper we formally define the Generic Adaptivity Model (GAM). This model provides a strong theoretical foundation for adaptive personalisation. Staying true to existing approaches in user modelling, the GAM can be used descriptively as well as prescriptively. The GAM consists of a number of pillars bound together by a common foundation. In order to allow for extensibility the GAM is doma...

Global gyrokinetic toroidal code (GTC) is used to study the low-frequency modes in tokamaks including geodesic acoustic mode (GAM) and beta-induced Alfvén eigenmode (BAE). GAM and BAE have the same frequency due to the geodesic curvature and thermal particle compressibility in toroidal plasmas. Important new insights include: the collisionless damping rate of the GAM is greatly enhanced by trap...

Identification of areas containing high biological diversity (‘hotspots’) from species presence-only data has become increasingly important in species and ecosystem management when presence/absence data is unavailable. However, as presence-only data sets lack any information on absences and as they suffer from many biases associated with the ad hoc or non-stratified sampling, they are often ass...

This paper examines the generalization characteristic of Gaussian ARTMAP (GAM) neural network in classification tasks. GAM performance for classification during training and testing is evaluated using the k-folds cross validation technique. A comparison is also done between GAM and Fuzzy ARTMAP (FAM) neural network. It is found that GAM performs better (98-99%) when compared to FAM (79-82%) usi...
