QUaD is a bolometric CMB polarimeter sited at the South Pole, operating at frequencies of 100 and 150 GHz. In this paper we report preliminary results from the first season of operation (austral winter 2005). All six CMB power spectra are presented derived as cross spectra between the 100 and 150 GHz maps using 67 days of observation in a low foreground region of approximately 60 deg. These dat...
Sensorimotor theories of semantic memory require overlap between conceptual and perceptual representations. One source of evidence for such overlap comes from neuroimaging reports of co-activation during memory retrieval and perception; for example, regions involved in color perception (i.e., regions that respond more to colored than grayscale stimuli) are activated by retrieval of object color...
We estimate the twoand three-dimensional power spectra, P2(K) and P3(k), of the galaxy distribution by applying a maximum likelihood estimator to pixel maps of the APM Galaxy Survey. The analysis provides optimal estimates of the power spectra and of their covariance matrices if the fluctuations are assumed to be Gaussian. Our estimates of P2(K) and P3(k) are in good agreement with previous wor...
BACKGROUND Health profession learners can foster clinical reasoning by studying worked examples presenting fully worked out solutions to a clinical problem. It is possible to improve the learning effect of these worked examples by combining them with other learning activities based on concept maps. This study investigated which combinaison of activities, worked examples study with concept map c...
This paper develops a formal model for metaphor and analogy built on information flow theory, formal concept analysis and conceptual graphs. Metaphor and analogy are important principles of human cognition based on representational maps. The model suggested in this paper defines metaphoric use in terms of information transfer via an information channel with respect to contextual constraints.
This paper assesses the impact of the Kyoto Protocol on CO2 emissions. With this aim a dynamic panel data model is estimated for a cross-section of 213 countries over the period 1960 to 2009. The model, based on a STIRPAT approach, also integrates the EKC approach and specifically considers the endogeneity of the policy variable. To sort out causality the number of financed CDM projects is used...
Today, the study of the spatial-temporal pattern of urban physical expansion and the identification of the parameters affecting the expansion play a crucial role in urban-related decision-making and long-term planning processes. Consequently, the use of precise and efficient methods to predict the physical expansion of urban areas is of great importance. The objective of present study is to pro...
