We consider singular-degenerate, multivalued stochastic fast diffusion equations with multiplicative Lipschitz continuous noise. In particular, this includes the stochastic sign fast diffusion equation arising from the BakTang-Wiesenfeld model for self-organized criticality. A well-posedness framework based on stochastic variational inequalities (SVI) is developed, characterizing solutions to t...

(Hetero)arylsulfur compounds where the S atom is in oxidation state VI represent a large percentage of molecular functionalities present organic chemistry. More specifically, (hetero)aryl-SVI fluorides have recently received enormous attention because their potential as chemical biology probes, result reactivity simple, modular, and efficient manner. Whereas synthesis application level 1 fluori...

Abstract Aims The prognostic impact of flow trajectories according to stroke volume index (SVi) and transvalvular rate (FR) in patients with severe aortic stenosis (AS) undergoing transcatheter valve replacement (TAVR) remains poorly assessed. We evaluated compared SVi FR prior after TAVR for AS. Methods results Patients were categorized (<35 ml/m2) (<200 ml/sec). association pre-...

BACKGROUND Most information on the causes of blindness has come from examining children in special education. To obtain a more representative population-based sample of children, a novel method was developed for ascertaining severe visually impaired (SVI) or blind (BL) children by training local volunteers to act as key informants (KIs). OBJECTIVE To compare the demography and cause of blindn...

PURPOSE To estimate the prevalence and causes of blindness and visual impairment (VI), and report the outcomes of cataract surgery in Chaonan Region, Guangdong Province, southern China. DESIGN Cross-sectional population-based survey. PARTICIPANTS A total of 3484 participants including 1397 men (40.1%) and 2087 women (59.9%) aged ≥50 years were examined (94.2% response rate). METHOD A two-...

BACKGROUND AND OBJECTIVE Accurate assessment of a patient's volume status is an important goal for an anaesthetist. However, most variables assessing fluid responsiveness are either invasive or technically challenging. This study was designed to compare the accuracy of arterial pressure-based stroke volume variation (SVV) and variations in the pulse oximeter plethysmographic waveform amplitude ...

The no Butterfly arbitrage domain of Gatheral SVI 5-parameters formula for the volatility smile has been recently described. It requires in general a numerical minimization 2 functions altogether with few root finding procedures. We study here case some sub-SVIs (all 3 parameters): Symmetric SVI, Vanishing Upward/Downward and SSVI, which we provide an explicit domain, procedure required.

BACKGROUND Randomized trials have shown an improvement in progression-free survival rates with adjuvant radiation therapy (ART) after radical prostatectomy for patients with a high risk of cancer recurrence. Less is known about the relative advantages and disadvantages of initial observation with delayed salvage radiation therapy (SRT). OBJECTIVE To examine the results of SRT in a large singl...

CONTEXT Correct assessment of tumour stage is crucial for prostate cancer (PCa) management. OBJECTIVE To assess the diagnostic accuracy of magnetic resonance imaging (MRI) for local PCa staging and explore the influence of different imaging protocols. EVIDENCE ACQUISITION We searched the PubMed, Embase, and Cochrane databases from 2000 up to August 2014. We included studies that used MRI fo...
