For a graph G, let V ar(G) denote the variance of the degree sequence of G, let sq(G) denote the sum of the squares of the degrees of G, and let t(G) denote the number of triangles in G and in its complement. The parameters are related by: V ar(G) = sq(G)/n− d where d is the average degree of G, and t(G) = ( n 3 ) + sq(G)/2−m(n− 1). Let V ar(n) denote the maximum possible value of V ar(G) where...

Amplification of the MYCN gene in neuroblastomas is a potent biological marker of highly aggressive tumors, which are invariably fatal unless sound clinical management is applied. To determine the usefulness of semi-quantitative differential PCR (SQ-PCR) for accurate quantification of MYCN gene copy number, we evaluated the analytical performance of this method by comparing the results obtained...

Condominium management (CM) businesses rely on continuous improvements to service quality (SQ) to increase consumer satisfaction (CS) and thereby improve operations. Lacking knowledge of SQ and CS results in poor efficiency. To develop cost-effective strategies for improvements, the relationship between SQ and CSmust be investigated. This work proposes novel procedures to explore the relationsh...

Regular magnetic daily quiet time (Sq) variations in total intensity of about 30 nT amplitude are determined in Universal Time (UT) from satellite magnetic field measurements. The CHAMP satellite traverses all hours of local time in 132 days and the Sq variations in total intensity are therefore calculated as an average over the 132 days for each hour of UT. Results are compared with the Sq dai...

Active dendrites can be viewed as linear classi"ers augmented by a few second-order product terms representing multiplicative synaptic interactions [4]. To quantify the degree to which local synaptic interactions could augment the memory capacity of a neuron, we have studied the family of `subsampled quadratica (SQ) classi"ers. Each SQ classi"er is a linear classi"er augmented by a subset k of ...

Sulfoquinovose (SQ, 6-deoxy-6-sulfoglucose) has been known for 50 years as the polar headgroup of the plant sulfolipid (Benson 1963, Benning 2007) in the photosynthetic membranes of all higher plants, mosses, ferns, algae, and most photosynthetic bacteria (Benning 1998). It is also found in some non-photosynthetic bacteria (Harwood and Nicholls 1979), and SQ is part of the surface layer of some...

We derive general bounds on the complexity of learning in the Statistical Query model and in the PAC model with classification noise. We do so by considering the problem of boosting the accuracy of weak learning algorithms which fall within the Statistical Query model. This new model was introduced by Kearns [12] to provide a general framework for efficient PAC learning in the presence of class...

INTRODUCTION Parks are an integral part of a favorable built environment, and several studies have found a positive association between a favorable built environment and physical activity. Parks data are available to researchers from various sources; however, the accuracy of data sources in representing parks is unknown. This study compared secondary parks data obtained from a commercial vendor...

We identified that the chemical linkage of the anticancer drug doxorubicin onto squalene, a natural lipid precursor of the cholesterol's biosynthesis, led to the formation of squalenoyl doxorubicin (SQ-Dox) nanoassemblies of 130-nm mean diameter, with an original "loop-train" structure. This unique nanomedicine demonstrates: (i) high drug payload, (ii) decreased toxicity of the coupled anticanc...
