We study the dynamic relation between aggregate mutual fund flow and market-wide volatility. Using daily flow data and a VAR approach, we find that market volatility is negatively related to concurrent and lagged flow. A structural VAR impulse response analysis suggests that shock in flow has a negative impact on market volatility: An inflow (outflow) shock predicts a decline (an increase) in v...

A new methodology is presented for the model estimation of an import–export pollution balance across country borders based on the classification of the synoptic scale atmospheric circulation. As an application, the transboundary transport of SO2 and NOx across the Greek borders is investigated for the year 1995. The annual total inflow–outflow fluxes were derived by weighting the model results ...

PURPOSE To propose an alternative method to characterize postocclusion surge using a collapsible artificial anterior chamber to replace the currently used rigid anterior chamber model. SETTING Fundación Oftamológica Los Andes, Santiago, Chile. METHODS The distal end of a phacoemulsification handpiece was placed inside a compliant artificial anterior chamber. Digital recordings of chamber pr...

Abstract We study the equilibrium configurations of a possibly asymmetric fluid–structure interaction problem. The fluid is confined in bounded planar channel and governed by stationary Navier–Stokes equations with laminar inflow outflow. A body immersed subject to both lift force from some external elastic force. Asymmetry, which motivated natural models, non-vanishing velocity on boundary req...

Amplitude-weighted mean velocity from continuous wave (CW) Doppler spectra was used to measure aortic flow (QAo) and left ventricular mitral inflow (QLVin). These flows were used to quantify mitral regurgitation fraction: RFm = (QLVin-QAo).QLVin-1.100(%).QLVin was calculated from the diastolic time integral of amplitude-weighted mean velocity that was derived from CW spectra with the transducer...

Of 279 patients with transposition of the great arteries, 14(5%) had narrowing of the aorta, including local coarctation (6), isthmus hypoplasia (6), isthmus atresia (1), and kinking of the aorta (1). There were six deaths in 10 surgically treated patients; in addition four patients died before operation. Two of the four survivors had a subpulmonary malalignment ventricular septal defect with a...
