Testing for the presence of a broken linear trend when the nature of the persistence in the data is unknown is not a trivial problem, since the test needs to be both asymptotically correctly sized and consistent, regardless of the order of integration of the data. In a recent paper, Sayginsoy and Vogelsang (2011) [SV] show that tests based on xed-b asymptotics provide a useful solution to this ...

Aneurysms of the sinus of Valsalva (SV) and the atrial septum are a rare association. We report the case of a 28-year-old woman, who was admitted to our department complaining of progressive dyspnea of 10 days of evolution, five hours previous to her admission to the hospital; she presented sudden oppressive anterior chest pain, accompanied by palpitations. The presence of rupture of the right ...

To simulate dynamic soft geo-objects and reflect geoscientific laws, the authors discuss the characteristics, mathematical expression, parameter representation and rendering of GIS Flow Element (FE) and GIS Soft Voxel (SV). The simulation and rendering algorithms of GIS FE and GIS SV are based on particle system and metaball technology in computer graphics. The main differences are that GIS FE ...

Primary seminal vesicle (SV) adenocarcinoma is a rare tumor. A small amount of data about the role of imaging to detect tumor recurrence is available. We report the case of a 58-year-old patient with primary SV clear-cell well-differentiated adenocarcinoma. Clinical and instrumental examinations were negative for the 32 months after treatments when computed tomography scan, [(18)F]fluoro-D-gluc...

We present results of concurrent maximum likelihood restoration implementations with spatially-variant point spread function (SV-PSF) on both synthetic and real datasets from the Hubble Space Telescope (HST). We demonstrate that SV-PSF restoration exhibits superior performance compared to restoration with a spatially invariant PSF. We realize concurrency on a network of Unix workstations, and a...

Background: Children with seizure disorder are often treated with sodium valproate (SV) on long-term basis. SV acts mainly through gamma amino butyric acid pathways, reducing the excitatory neurotransmission and modifying the monoamine concentration. Altered monoamine concentration by SV is expected to cause movement disorder and cognitive dysfunction, considered reversible after the withdrawal...

BACKGROUND This study aimed to evaluate whether treatment with sodium valproate (SV) was associated with reduced risk of stroke or myocardial infarction (MI). METHODS Electronic health records data were extracted from Clinical Practice Research Database for participants ever diagnosed with epilepsy and prescribed antiepileptic drugs. A nested case-control study was implemented with cases diag...

growing demand for wheat grain with optimal technological parameters results in looking for the possibilities of accurately meeting the plant needs. environmental conditions in the surroundings of germinating grains can be improved by application of humic preparations. qualitative features of grain can be also changed by foliar application of potassium, which is the activator of enzymes catalys...
