We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

Despite Leonardo da Vinci's observation (circa 1511) that "the atria or filling chambers contract together while the pumping chambers or ventricles are relaxing and vice versa," the dynamics of four-chamber heart function, and of diastolic function (DF) in particular, are not generally appreciated. We view DF from a global perspective, while characterizing it in terms of causality and clinical ...

BACKGROUND Regional left ventricular (LV) diastolic wall motion abnormalities detected by color kinesis (CK), an echocardiographic technique, may be a more sensitive measure to postischemic damage following coronary spasm than parameters of global diastolic function. METHODS AND RESULTS Regional LV diastolic wall motion was evaluated by using CK in 18 patients with variant angina on the day f...

T first of the Millennium Development Goals targets global poverty.1 The global poverty number is estimated by the World Bank as a worldwide count of people who live below a common international poverty line. This line, loosely referred to as the dollar-a-day line, is calculated as an average over the world’s poorest countries of their national poverty lines expressed in international dollars; ...

The adoption of a global index (GI) for performance evaluation has been increasingly recognized as useful strategy decision-making it simplifies the interpretation and monitoring results. Because GI is often built by adopting combination different procedures normalization, weighting, aggregation indicators, challenging to select optimal procedures, since countless combinations lead This paper p...

The clinical evaluation of right ventricular (RV) contractility is problematic because instantaneous RV volumetry is difficult to achieve. Our aim was to test whether global RV contractility can be assessed by using regional indexes in the longitudinal and/or circumferential axis. Six anesthetized adult ewes were instrumented with a RV conductance catheter and four RV free wall sonomicrometry c...

Social reciprocity may explain certain emerging psychological processes likely to be founded on dyadic relations. Although indexes and statistics have been proposed to measure and make statistical decisions regarding social reciprocity in groups, these tools were generally developed to identify association patterns rather than to quantify the discrepancies between what each individual addresses...

In this paper, variability analysis was performed on the model calibration methodology between a multi-camera system and a LiDAR laser sensor (Light Detection and Ranging). Both sensors are used to digitize urban environments. A practical and complete methodology is presented to predict the error propagation inside the LiDAR-camera calibration. We perform a sensitivity analysis in a local and g...

This paper introduces the geometric continuity equations of the closed planar polygons and gives the definition of a morphing with geometric continuity between two arbitrary planar polygons, including simple, non-3 and even degenerated polygons. A simple morphing technique based on linear interpolation of the geometric continuity equations is proposed. The closureness of the in-between polygons...
