This study used taxometric methods to investigate the latent structure of the construct of marital adjustment as indexed by the Marital Adjustment Test (MAT; H. J. Locke & K. M. Wallace, 1959). That is, the authors examined whether marital adjustment is best thought of as a "dimension" of adjustment only or whether there also are categorical differences between "discordant" and "nondiscordant" ...

Characterization of the correlations of a multiparticle system remains an open problem. We generalize the notion of quantum discord, using multivariate mutual information, to characterize the quantum properties of a multiparticle system. This new measure, called dissension, is a set of numbers – quantumness vector. There are a number of different possible generalizations. We consider two of the...

We present an operational interpretation of quantum discord based on the quantum state merging protocol. Quantum discord is the markup in the cost of quantum communication in the process of quantum state merging, if one discards relevant prior information. Our interpretation has an intuitive explanation based on the strong subadditivity of von Neumann entropy. We use our result to provide opera...

In this work, we introduce some novel heuristics which can enhance the efficiency of the Heuristic Discord Discovery (HDD) algorithm proposed by Keogh et al. for finding most unusual time series subsequences, called time series discords. Our new heuristics consist of a new discord measure function which helps to set up a range of alternative good orderings for the outer loop in the HDD algorith...

Advancing the process-oriented study of links between interparental discord and child adjustment, 2 multimethod prospective tests of emotional security as an explanatory mechanism are reported. On the basis of community samples, with waves spaced 2 years apart, Study 1 (113 boys and 113 girls, ages 9-18) identified emotional security as a mediator in a 2-wave test, whereas Study 2 (105 boys and...

Discord, originally notable as a signature of bipartite quantum correlation, in fact can be nonzero classically, i.e. arising from noisy measurements by one the two parties. Here we redefine classical discord to quantify channel distortion, contrast previous restriction state, and then show monotonic relationship between (channel) distortion. We that is equivalent (doubly stochastic) distortion...
