The echocardiogram at rest was encouraging and showed the same LVEF and a mild MR. The TTG was 22 mmHg. We decided to perform exercise Doppler echocardiography to understand the discrepancy ...

The KCRA 3 weather team is issuing Impact Days through Tuesday because back-to-back storm systems will bring waves of rain and snow that can affect outdoor activities and travel.

When NASA and the Indian Space Research Organization's (ISRO) new Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar) launches in coming months, it will capture images of Earth's surface so ...

Rain and snow showers could start by late Friday morning. A nearly four week stretch of dry winter weather in Northern ...

NASA's Jet Propulsion Laboratory used radar data taken by ESA's Sentinel-1A satellite before and after the 2015 eruption of the Calbuco volcano in ...

Echocardiography is widely used for this, but the subjectivity of visual observation may hamper accurate evaluation. The analysis of myocardial velocity and strain by tissue Doppler and speckle ...

Abstract: Time delay and Doppler shift between the echo signal and the reference signal are two most commonly used measurements in target localization for the passive radar. Doppler rate, which can be ...

When NASA and the Indian Space Research Organisation’s (ISRO) new Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar) ...

This is even more common with Doppler radars due to their higher sensitivity. As you move further away from the radar, the returned echo becomes weaker. This occurs because as the radar beam broadens ...

Thus a weak echo may not mean that it is raining at the ground because ... Why isn't the 64km view available for most radars? Only Doppler radars (denoted by a black diamond on the radar selection map ...
