medical image registration methods which use mutual information as similarity measure have been improved in recent decades. mutual information is a basic concept of information theory which indicates the dependency of two random variables (or two images). in order to evaluate the mutual information of two images their joint probability distribution is required. several interpolation methods, su...

background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...

We report on the association of an X-ray source (WGA J2025.1+3342), serendipitously found with BeppoSAX in two separate observations, with the unidentified EGRET source 3EG J2027+3429. The source is detected from 1 keV up to about 100 keV, has a flat (Γ=0.6-1.5) spectrum and is highly variable both in intensity and shape. The data indicate marginal evidence for an iron line in the source rest f...

The recent developments in wearable devices and the Internet of Medical Things (IoMT) allow real-time monitoring recording electrocardiogram (ECG) signals. However, continuous ECG signals is challenging low-power due to energy memory constraints. Therefore, this article, we present a novel energy-efficient methodology for continuously heart devices. proposed composed three different layers: 1) ...

We report the discovery of a new radio galaxy within the location error box of the γ-ray source 3EG J1735−1500. The galaxy is a double-sided jet source forming a large angle with the line of sight. Optical observations reveal a V ∼ 18 magnitude galaxy at the position of the radio core. Although the association with the EGRET source is not confirmed at the present stage, because there is a compe...
