We previously reported that plasma levels of glycine, a co-agonist at N-methyl-D-asparate (NMDA)-type glutamate receptors, are decreased in patients with schizophrenia, and that glycine levels are negatively correlated with negative symptoms. The aim of the present study was to determine if glycine, or its ratio to serine, a precursor of glycine, predicts change in negative symptoms in subjects...
A quantum statistical parametrization of parton distributions has been considered. In this framework, the exclusion Pauli principle connects the violation of the Gottfried sum rule with the Ellis and Jaffe one, and implies a defect in the Bjorken sum rule. However, in terms of standard parametrizations of the polarized distributions a good description of the data is obtained once a large gluon ...
We introduce the Laplacian sum-eccentricity matrix LS_e} of a graph G, and its Laplacian sum-eccentricity energy LS_eE=sum_{i=1}^n |eta_i|, where eta_i=zeta_i-frac{2m}{n} and where zeta_1,zeta_2,ldots,zeta_n are the eigenvalues of LS_e}. Upper bounds for LS_eE are obtained. A graph is said to be twinenergetic if sum_{i=1}^n |eta_i|=sum_{i=1}^n |zeta_i|. Conditions ...
Rheumatoid arthritis (RA) is a bone destructive autoimmune disease. Many patients with RA recognize fluctuations of their joint synovitis according to changes of air pressure, but the correlations between them have never been addressed in large-scale association studies. To address this point we recruited large-scale assessments of RA activity in a Japanese population, and performed an associat...
We introduce a refinement of the persistence diagram, graded diagram. It is Möbius inversion rank function, which obtained from function using unary numeral system. Both diagrams and are integer-valued functions on Cartesian plane. Whereas diagram takes non-negative values, values 0, 1, or $$-1$$ . The sum show that positive negative points in kth correspond to local maxima minima, respectively...
Light-cone QCD sum rules are employed to compute the strong coupling constants: gB∗B∗π, gB1B0π and gB1B∗π, where (B,B ∗) and (B0, B1) are negative and positive parity (0−, 1−) and (0+, 1+) q̄Q doublets. The couplings are calculated both for finite values of the heavy quark mass and in the infinite heavy quark mass limit, deriving sum rules for mQ → ∞. PACS:11.55.Hx,13.20.He
Multiplier conditions equivalent to the constructive boundedness of a non-negative real sequence M are derived. If the termwise product sM is bounded in sum whenever s is bounded in sum, then an upper bound for M can be constructed. One consequence is a constructive generalization of Fichtenholz's characterization of Lipschitz functions on metric spaces. The appropriate Lipschitz constants are ...
