Accessory mitral valve tissue, a rare cause of left ventricular outflow tract obstruction, can be difficult to diagnose preoperatively and confusing even at surgery. The reported case illustrates how preoperative evaluation can be made using two-dimensional echocardiography combined with Doppler flow analysis. The intraoperative technique for removing the accessory tissue without causing damage...

The Federal Aviation Administration (FAA) method for sizing small detention and retention basins is a volume-based approach that is sensitive to the release rate. In practice, such a release rate is often approximated by open channel hydraulics or culvert hydraulics. Without a consistent guideline, this practice of approximation can result in significant discrepancy or violation of the volume b...

In this paper we study the contribution of inflows and outflows to the dynamics of unemployment in three European countries, the United Kingdom, France and Spain. We compare performance in these three countries making use of both administrative and labor force survey data. We find that the impact of the 1980s reforms in Britain is evident in the contributions of the inflow and outflow rates. Th...

The Ins and Outs of European Unemployment In this paper we study the contribution of inflows and outflows to the dynamics of unemployment in three European countries, the United Kingdom, France and Spain. We compare performance in these three countries making use of both administrative and labor force survey data. We find that the impact of the 1980s reforms in Britain is evident in the contrib...

ABSTRACT We use the 30 simulations of Auriga Project to estimate temporal dependency inflow, outflow, and net accretion rates onto discs Milky Way-like galaxies. The are found be similar for all galaxies at early times, increasing rapidly up $\sim 10~\mathrm{M}_\odot \, \mathrm{yr}^{-1}$. After ∼6 Gyr evolution, however, diverse: in most galaxies, these exhibit an exponential-like decay, but so...

A hydraulic fluid impedance plot is produced by plotting instantaneous differential pressure against phasic blood flow across a vascular segment. This simple plot quantitatively and compactly describes the changes in flow resistance (impedance) throughout the entire cardiac cycle. Impedance plots were obtained before and after corrective surgery in patients with a variety of left ventricular ou...

CSF-hydrodynamic investigation using the constant pressure infusion method was used in children. The CSF resting pressure was recorded and the CSF formation rate was measured. The conductance of the CSF outflow pathways and the pressure in the sagittal sinus were calculated. The method was used in children with suspicion of disturbed CSF hydrodynamics due to various neurological and other condi...

This paper studies worker flows dynamics in Japan for the period between 1980 and 2009. We construct gross worker flows data from the monthly Labour Force Survey. Our data enables us to examine the size and cyclical patterns of the flows and transition rates between the states of employment, unemployment, and not-in-the labor force. We find that the cyclical pattern of worker flows is similar t...
