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...

The interaction of heparin with heparin binding growth-associated molecule (HB-GAM) was studied using isothermal titration calorimetry (ITC) and surface plasmon resonance (SPR). ITC studies showed that, in solution, heparin bound HB-GAM with a deltaH of -30 kcal/mole corresponding to a dissociation constant (Kd) of 460 nM. The stoichiometry of interaction was 3 moles of HB-GAM per mole of hepar...

Geodesic Acoustic Modes (GAM) are shown to constitute a continuous spectrum due to radial inhomogeneities. The existence of a singular layer causes GAM to mode convert to short-wavelength kinetic GAM (KGAM) via finite ion Larmor radii; analogous to kinetic Alfvén waves (KAW). KGAM are shown to propagate radially outward; consistent with experimental observations and numerical simulation results...

This article discusses the General Aggression Model (GAM), which provides a comprehensive and integrative social–cognitive framework for understanding aggression and violence. After providing a brief description of the basic components of GAM, we discuss how it can be used to better understand 4 topics related to phenomena that occur primarily outside the laboratory and apply to a broad range o...

Bone has an enormous capacity for growth, regeneration, and remodeling. This capacity is largely due to induction of osteoblasts that are recruited to the site of bone formation. The recruitment of osteoblasts has not been fully elucidated, though the immediate environment of the cells is likely to play a role via cell- matrix interactions. We show here that heparin-binding growth-associated mo...
