BACKGROUND The convolution approach to thyroid time-activity curve (TAC) data fitting with a gamma distribution convolution (GDC) TAC model following bolus intravenous injection is presented and applied to 99mTc-MIBI data. The GDC model is a convolution of two gamma distribution functions that simultaneously models the distribution and washout kinetics of the radiotracer. The GDC model was fitt...

Loops without dependence8 among iterations are a rich source of paTalle&sm in many applications. Among these type8 of loops, non-uniform loops with vatiable execution times need eficient scheduling schemes to take advantages of the capabilities of parallel machines. In this paper, we present a global distributed control scheme (GDC) to schedule nonuniform loops on distributed memory parallel ma...

We report herein a 63-year-old female with gastric duplication cyst (GDC), of which resected specimen was histologically shown to be composed of gastric foveolar epithelium and thin bundles of smooth muscle. Computed tomography revealed a thin-walled cystic lesion surrounded by the pancreatic tail, spleen, left kidney, and the stomach. Magnetic resonance imaging demonstrated a thin layer betwee...

BACKGROUND Matrix coils are based on Gugliemi detachable coils (GDC) but are covered with polyglycolic/polylactic acid. We present our experience regarding the immediate posttreatment results of aneurysm embolization using the 2 coil systems. PATIENTS We embolized 219 aneurysms in 187 patients with the use of GDCs and 145 aneurysms in 120 patients with the use of Matrix coils. Age, sex distri...

The electrochemical performance and carbon deposition on palladium catalyst promoted Ni/Gd0.1C0.9O1.95 (Ni/GDC) anode in methane and alcohol fuels like methanol and ethanol are investigated at open circuit potential and under dc bias using electrochemical impedance spectroscopy technique. Presence of Pd nanoparticle catalyst significantly promotes the electrocatalytic activity of Ni/GDC for the...

Deregulation of the Phosphoinositide 3-kinase (PI3K)/AKT signalling network is a hallmark of oncogenesis. Also medulloblastoma, the most common malignant brain tumor in children, is characterized by high levels of AKT phosphorylation and activated PI3K signalling in medulloblastoma is associated with enhanced cellular motility, survival and chemoresistency underscoring its role of as a potentia...

The cerebellum of BALB/cJ mice has approximately 2.5 times as much glycerol-3-phosphate dehydrogenase (GPDH) as that of C57BL/6J mice. This difference in enzyme levels, which positively correlates with similar differences in the levels of hybridizable GPDH mRNA, is controlled by at least two unlinked regulatory loci and the structural gene, Gdc-1, located on chromosome 15. These regulatory loci...

We herein report an impedance spectroscopy study of Au electrodes on Gd-doped CeO2 (GDC) – molten Li2CO3+Na2CO3 (LNC) composite electrolytes in O2 and O2+CO2 atmospheres. Complementary measurements GDC alone are provided for supporting insight. find that the adsorption CO2 atmospheres effectively blocks oxygen severely slows reduction kinetics. The conductivity is dominated by phase solid-solid...

The tribological performance and friction-induced vibration of Gd0.2-Ce0.8O1.9 (GDC) reinforced nickel oxide (NiO) metal matrix composites prepared via sintering on the performance, as well friction induced were investigated. Compared to pure NiO, exhibit improved mechanical properties, such a relatively high dislocation density, hardness small grain size. results show that GDC-reinforced NiO n...
