Lower Bounds of Concurrence for Multipartite States

, 2012
We study the entanglement of multipartite quantum states. Some lower bounds of the multipartite concurrence are reviewed. We further present more effective lower bounds for detecting and qualifying entanglement, by establishing functional relations ...

Functional connectivity of hippocampal subregions in PTSD: relations with symptoms

BMC Psychiatry, 2018
Background Posttraumatic stress disorder (PTSD) is associated with abnormal hippocampal activity; however, the functional connectivity (FC) of the hippocampus with other brain regions in PTSD and its relations with symptoms warrants further attention. We

Fifth-neighbor spin-spin correlator for the anti-ferromagnetic Heisenberg chain

, 2005
We study the generating function of the spin-spin correlation functions in the ground state of the anti-ferromagnetic spin-1/2 Heisenberg chain without magnetic field.

Detection of Functional Form Misspecification in Cointegrating Relations [PDF]

A simple specification test based on fully modified residuals and the CUSUM test for cointegration of Xiao and Phillips (Journal of Econometrics, 2002) are considered as means of testing for functional form in long-run cointegrating relations.

Aspects of the Functional Renormalisation Group

, 2005
We discuss structural aspects of the functional renormalisation group. Flows for a general class of correlation functions are derived, and it is shown how symmetry relations of the underlying theory are lifted to the regularised theory. A simple equation

Fusion hierarchies, $T$-systems and $Y$-systems for the $A_2^{(1)}$ models

, 2018
The family of $A^{(1)}_2$ models on the square lattice includes a dilute loop model, a $15$-vertex model and, at roots of unity, a family of RSOS models.

Intragroup relations of cadets as indicators of the social and psychological climate at diff erent stages of higher education [PDF]

Известия Саратовского университета. Новая серия: Акмеология образования. Психология развития
The relevance of the study is due to the fact that assessment of intragroup relations is one of the means of studying social and psychological climate in a group; its use allows timely solving the problem of preventing confl icts and tension within the ...
