The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and ...
Understanding molecular femtosecond dynamics under intense X-ray exposure is critical to progress in biomolecular imaging and matter under extreme conditions. Imaging viruses and proteins at an atomic spatial scale and on the time scale of atomic motion requires rigorous, quantitative understanding of dynamical effects of intense X-ray exposure. Here we present an experimental and theoretical s...
In this note we demonstrate the occurrence of first-order transitions in temperature for some recently introduced generalized XY models, and also 1 point out the connection between them and annealed site-diluted (lattice-gas) continuous-spin models.
Listener perceptions of changes in the arousal expressed by classical music have been found to correlate with changes in sound intensity/loudness over time. This study manipulated the intensity profiles of different pieces of music in order to test the causal nature of this relationship. Listeners (N = 38) continuously rated their perceptions of the arousal expressed by each piece. An extract f...
We illustrate the thesis that if time did not exist, we would have to create it if space is noncommutative, and extend functions by something like Schroedinger’s equation. We propose that the phenomenon is a somewhat general mechanism within noncommutative geometry for ‘sponteneous time generation’. We show in detail how this works for the su2 algebra [xi, xj ] = 2ıλǫijxk as noncommutative spac...
Using a recursive approach, we obtain a simple exact expression for the L-distance from the limit in the classical limit theorem of Régnier (1989) for the number of key comparisons required by QuickSort. A previous study by Fill and Janson (2002) using a similar approach found that the d2-distance is of order between n−1 logn and n−1/2, and another by Neininger and Ruschendorf (2002) found that...
Results are given for aggregating a system of nonnegative integer equations of the form Xj = bj, je N, to yield a single equivalent equation whose coefficients correspond to those of the best previously known result for the special case b, = 1, jc,V. Different aggregations are obtained for different permutations of the indexes jEIV, according to the sizes of the b, values, and we also identify ...
The integral octonions arise from the octonion XY-product. A parallel is shown to exist with the quaternion Z-product. Connections to the laminated lattices in dimensions 4, 8, 16 and 24 (Leech) are developed.
We deal with the reversible dynamics of coupled quantum and classical systems. Based on a recent proposal by authors, we exploit theory hybrid quantum–classical wavefunctions to devise closure model for in which both density matrix Liouville distribution retain their initial positive sign. In this way, evolution allows identifying state interaction at all times, thereby addressing series string...
