A straightforward calculation reveals the essentially nonlocal character of the leading heavy Q Q interaction arising from nonperturbative gluon eld correlations in the model of a uctuating QCD vacuum. In light of this quarkonium spin splitting ratio predictions which have supported the scalar connnement ansatz are reconsidered as a speciic example of possible consequences for spectroscopy. A g...

Let I , H , S , P , Pf be the usual operators on classes of algebras of the same type (Pf for filtered products). The partially ordered monoid generated by the operators H , S , P with respect to composition of operators, I as an identity element, and a natural ordering between operators is described by Pigozzi (Algebra Universalis 2 (1972), 346–353). Let us denote by M = 〈H,S, P 〉 and by Mf = ...

Standard calibration methods used to determine trace analytes usually yield significant deviations from the actual analyte value in the presence of interferents in the assay media. These deviations become of particular concern when the concentration of the analyte is low, and when the results are used to draw mechanistic or kinetic conclusions, for instance in enzyme structure-function studies....

NAD(P)H quinone oxidoreductase 1 (NQO1) is an antioxidant and detoxifying enzyme involved in the two-electron reduction of a wide variety of quinones. As a non-enzymatic function, it is involved in the stabilization of several tumour suppressors such as p53, p33 and p73α. NQO1 is overexpressed in several types of tumours, and two common polymorphisms are associated with increased cance...

Availability of farmers markets may increase fruit and vegetable consumption among rural residents of the United States. We conducted a community-based marketing campaign, Plate it Up Kentucky Proud (PIUKP), in 6 rural communities over 2 years to determine the association between exposure to the campaign and fruit and vegetable purchases, adjusted for Supplemental Nutrition Assistance Program r...

In the current study, we examined latent growth in 731 young children's inhibitory control from ages 2 to 4, and whether demographic characteristics or parenting behaviors were related to initial levels and growth in inhibitory control. As part of an ongoing longitudinal evaluation of the Family Check-Up (FCU), children's inhibitory control was assessed yearly at ages 2, 3, and 4. Inhibitory co...

This pilot study examined the effectiveness of an attachment-based intervention program, PRERAYMI, based on video technique, psychological counseling and developmental guidance in improving the style of interaction and emotion regulation of adolescent mothers and their infants after 3 and 6 months of intervention. Analyses revealed that adolescent mothers who participated in the intervention (v...
