heart,organthat serves as a pump tocirculatetheblood. It may be a straight tube, as in spiders and annelid worms, or a somewhat moreelaboratestructure with one or more receiving chambers (atria) and a main pumping chamber (ventricle), as in mollusks. Infishesthe heart is a folded tube,...
Heart Structure A normal heart consists of 4 chambers – 2 atria and 2 ventricles. The main pumping chamber of the heart is the left ventricle. It pumps oxygenated blood up to the aorta to go right around the whole body and to be returned by veins to the right side of the heart and ...
Every cotilting module over a ring R induces a t-structure with a Grothendieck heart in the derived category D(Mod-R). We determine the simple objects in this heart and their injective envelopes, combining torsion-theoretic aspects with methods from the model theory of modules and Auslander-Rei...
Figure 1.Anterior view of adult chicken heart. This diagram shows a longitudinal section from an adult avian heart fromLu et al. (1993a). This diagram illustrates the basic structure of the avian heart with the relative thicknesses of atria (RA and LA) and ventricles (RV and LV). The ...
Advantages: TAPSE is simple, less dependent on optimal image quality, and reproducible, and it does not require sophisticated equipment or prolonged image analysis. Disadvantages: TAPSE assumes that the displacement of a single segment represents the function of a complex 3D structure. Furthermore, it...
The CNN-LSTM-SE model proposed in this paper has the characteristics of simple structure and lightweight. Noise filtering, feature extraction and selection techniques are not required. 3. Discuss the effect of different length ECGs of patients with heart failure on heart failure classification, and...
The structure of our pipeline has various advantages over manual analysis or already existing methods. First, using the ImageJ macro language, application-specific adaptations, and customizations are easy to implement. We have exemplarily shown this for the analysis of cardiomyocyte nuclei, pro-ANP ...

Physiological systems vary in a day-night manner anticipating increased demand at a particular time. Heart is no exception. Cardiac output is primarily determined by heart rate and unsurprisingly this varies in a day-night manner and is higher during the
3D CNN, 3D CNN with temporal encoder-decoder (ED) structure, and 2D CNN combined with RNN for further comparison. All variants were trained and validated under the OBF dataset. The result showed that 3DCNN-ED achieved the best performance in HR estimation compared to the worst case, RNN’s...
