Three cases are reported of concurrence of malignant gliomas (astrocytomas and glioblastomas) with multiple sclerosis (MS). This situation may lead to considerable diagnostic difficulties, yet an accurate appraisal is of prognostic, if not therapeutic, value. There is suggestive but inconclusive evidence that the two conditions may be causally related, malignant astrocytic tumours arising from ...

We perform a numerical study on the concurrence of the ground state Heisenberg XXX with next-nearest-neighbor interaction with open and periodic boundary condition.

Quantifying genuine entanglement is a key task in quantum information theory. We study the quantification of multipartite for four-qubit systems. Based on concurrence nine different classes states, with each class being closed under stochastic local operation and classical communication, we construct tetrahedron. Proper measure presented by using volume For non entangled pure classifies bi-sepa...

Congenital hypothyroidism has been found in four patients with Klinefelter's syndrome. It is likely that this reflects more than chance concurrence of these conditions.

We propose generalizations of concurrence for multipartite quantum systems that can distinguish qualitatively distinct quantum correlations. All introduced quantities can be evaluated efficiently for arbitrary mixed sates.

In this work we study the steady state entanglement between two qubits interacting asymetrically with a common non-Markovian environment. Depending on initial two-qubit state, asymmetry in couplings each qubit and environment may lead to enhanced of system, measured terms concurrence. Our results indicate that, if qubit-qubit interaction is also present, concurrence always favored by symmetric ...

INTRODUCTION Multiple sclerosis (MS) is a chronic demyelinating inflammatory disease of the central nervous system (CNS) with multifactorial pathogenesis that includes genetic and environmental factors. A primary brain tumor is a neoplasm developing from the cells of the brain. There is high heterogeneity of primary brain tumors (about 100 different types); however, most of them develop from th...

Early histological changes in the thyroid gland were examined in 30 patients with juvenile thyrotoxicosis, by means of needle biopsy. Based on the degree of lymphocytic infiltration and degenerative changes in follicular epithelium, results were classified into four groups. A: hyperplastic changes without cellular infiltration (6 patients, 20%); B: hyperplastic changes with areas of focal thyro...

The topological data analysis method “concurrence topology” is applied to mutation frequencies in 69 genes in glioblastoma data. In dimension 1 some apparent “mutual exclusivity” is found. By simulation of data having approximately the same second order dependence structure as that found in the data, it appears that one triple of mutations, PTEN, RB1, TP53, exhibits mutual exclusivity that depe...
