We have analyzed archival Hubble Space Telescope/Advanced Camera for Surveys images in g and z of the globular cluster (GC) systems of 53 ellipticals in the Virgo Cluster, spanning massive galaxies to dwarf ellipticals (dEs). Several new results emerged: (i) In the giant ellipticals (gEs) M87 and NGC 4649, there is a correlation between luminosity and color for individual metal-poor GCs, such t...

Background: It is pertinent to objectively assess the severity of diabetic gastroparesis and tailor treatment accordingly. The current study was planned to document gastroparesis by gastric emptying scintigraphy (GES) objectively and see the effect of medications and diet control on clinical and GES after four weeks. Methods: A prospective, open-label randomized trial was conducted in the Depa...

AIM To evaluate the agreement of multichannel intraluminal impedance-pH monitoring (MII-pHM) and gastroesophageal reflux scintigraphy (GES) for the diagnosis of gastroesophageal reflux disease. METHODS Seventy-five consecutive patients with suspected gastroesophageal reflux disease (GERD) underwent 24-h combined MII-pHM recording and one hour radionuclide scintigraphy during the course of the...

This paper considers the globally exponential synchronization (GES) of the family of Rössler chaotic systems. One pair of the six transmitter-receiver systems is specifically studied, and algebraic criterion for the GES is obtained via proper nonlinear feedback controls. Based on the study of the systems’ structures, appropriate Lyapunov functions are constructed for error systems. The method p...

Previous research has shown that glycolytic enzymes (GEs) exist as multi-enzyme complexes on the inner surface of human erythrocyte membranes. Because GE binding sites have been mapped to sequences on the membrane protein, band 3, that are not conserved in other mammalian homologs, the question arose whether GEs can organize into complexes on other mammalian erythrocyte membranes. To address th...

Targeting vectors for embryonic stem (ES) cells typically contain a mouse gene segment of >7 kb with the neo gene inserted for positive selection of the targeting event. More complex targeting vectors carry additional genetic elements (e.g. lacZ, loxP, point mutations). Here we use homologous recombination in yeast to construct targeting vectors for the incorporation of genetic elements (GEs) i...

A class of discrete-time recurrent neural networks for solving quadratic optimization problems over bound constraints is studied. The regularity and completeness of the network are discussed. The network is proven to be globally exponentially stable (GES) under some mild conditions. The analysis of GES extends the existing stability results for discrete-time recurrent networks. A simulation exa...
