Distance-dependent defensive coloration
spatial frequencies (as projected onto the retina) and these will dominate perceptual grouping mechanisms. With increasing distance, the highest frequencies are lost, and the components of the visual scene to which the viewer is most sensitive change systematically [10]. The multi-scale processing of images has been exploited to create hybrid pictures that vary with distance in, for example, pe...
متن کاملAge-dependent allocation of carotenoids to coloration versus antioxidant defences.
Aging is commonly attributed to age-related changes in oxidative damage due to an increased production of reactive oxygen species (ROS) and a weakened efficacy of enzymatic antioxidants. These age-related changes might therefore modify the use of dietary antioxidants, including carotenoids. As carotenoids are closely associated with the expression of secondary sexual signals, the allocation of ...
متن کاملDistance dependent Chinese restaurant processes
We develop the distance dependent Chinese restaurant process, a flexible class of distributions over partitions that allows for dependencies between the elements. This class can be used to model many kinds of dependencies between data in infinite clustering models, including dependencies arising from time, space, and network connectivity. We examine the properties of the distance dependent CRP,...
متن کاملDistance Dependent Localization Approach in Oil Reservoir History Matching: A Comparative Study
To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of the Kalman filter: the Ensemble Kalman Filter (EnKF). The EnKF not only estimate uncertain parameters but also provide a recursive estimat...
متن کاملA two-dimensional neuropsychology of defense: fear/anxiety and defensive distance.
We present in this paper a picture of the neural systems controlling defense that updates and simplifies Gray's "Neuropsychology of Anxiety". It is based on two behavioural dimensions: 'defensive distance' as defined by the Blanchards and 'defensive direction'. Defensive direction is a categorical dimension with avoidance of threat corresponding to fear and approach to threat corresponding to a...
