PURPOSE The purpose of this study is to evaluate the results of spinal cord protection based on selective reconstruction of the segmental arteries. METHODS Twenty-one patients who underwent repair of aneurysms (nine descending thoracic and 12 thoracoabdominal: three type I, six type II, and three type III) were analyzed. Ten patients had postdissection aneurysms. Operative techniques consiste...
This paper deals with the application of distributed source coding (DSC) theory to remote sensing image processing systems. We first provide a brief overview of DSC of correlated information sources. We discuss several possible applications of DSC in a remote sensing system, aimed at improving the performance of on-board, on-the-ground and hybrid lossless image compression systems. We then focu...
Background: Alterations in striatal dopamine neurotransmission are central to the emergence of psychotic symptoms and to the mechanism of action of antipsychotics. Although the functional integrity of the presynaptic system can be assessed by measuring striatal dopamine synthesis capacity (DSC), no quantitative meta-analysis is available. Methods: Eleven striatal (caudate and putamen) [C/F]DOPA...
BACKGROUND AND PURPOSE Histopathologic evaluation remains the reference standard for diagnosis of glioma and classification of histologic subtypes, but is challenged by subjective criteria, tissue sampling error, and lack of specific tumor markers. Anatomic imaging is essential for surgical planning of gliomas but is limited by its nonspecificity and its inability to depict beyond morphologic a...
BACKGROUND The thermal decomposition of cephalexine, cefadroxil and cefoperazone under non-isothermal conditions using the TG, respectively DSC methods, was studied. In case of TG, a hyphenated technique, including EGA, was used. RESULTS The kinetic analysis was performed using the TG and DSC data in air for the first step of cephalosporin's decomposition at four heating rates. The both TG an...
Introduction Cerebral blood volume (CBV) in brain tumours reflects vascularity and can be used to differentiate intracranial tumour types. Measurement of CBV with dynamic susceptibility weighted imaging (DSC-MRI) requires injection of a contrast agent. As an alternative, a recently introduced, model-free arterial spin labelling technique (ASL) named QUASAR enables quantification of cerebral blo...
INTRODUCTION Blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI) during manipulation of inhaled carbon dioxide (CO2) can be used to measure cerebrovascular reactivity (CVR) and map regions of exhausted cerebrovascular reserve. These regions exhibit a reduced or negative BOLD response to inhaled CO2. In this study, we sought to clarify the mechanism behind the negative BOLD resp...

Tungsten dioxide (WO(2)) nanorods were synthesized, which showed excellent catalytic activity for the reduction of triiodide to iodide. The dye-sensitized solar cell (DSC) using WO(2) as a counter electrode (CE) reached a high energy conversion efficiency of 7.25%, which can match the performance of the DSC based on a Pt CE.
Large eddy simulation of turbulent flow is given a natural setting in the DSC framework of computational fluid dynamics. Periodic cellular coarsegraining prevents the nodal flow from piling up and preserves its large patterns. The coarsening operations are consistent with the near-field interaction principle of DSC and therefore uncomplicated at boundaries. Numerical examples validate the appro...
