Modeling sarcoplasmic reticulum Ca in rat cardiomyocytes.

The sarcoplasmic reticulum (SR) primarily serves as the intracellular Ca store in cardiac myocytes, mediating cellular function under cardiac physiology and diseases. However, the properties of cardiac SR Ca have not yet been fully determined, particularly in rats and mice, which are the most commonly used experimental species in studies on cardiac physiology and diseases. Here, we developed a spatially detailed numerical model to deduce Ca movements inside the junctional SR (jSR) cisternae of rat cardiomyocytes.

Calcium Spark Detection and Event-Based Classification of Single Cardiomyocyte Using Deep Learning.

Ca sparks are the elementary Ca release events in cardiomyocytes, altered properties of which lead to impaired Ca handling and finally contribute to cardiac pathology under various diseases. Despite increasing use of machine-learning algorithms in deciphering the content of biological and medical data, Ca spark images and data are yet to be deeply learnt and analyzed. In the present study, we developed a deep residual convolutional neural network method to detect Ca sparks.

PATL: A RFID Tag Localization based on Phased Array Antenna.

In RFID systems, how to detect the position precisely is an important and challenging research topic. In this paper, we propose a range-free 2D tag localization method based on phased array antenna, called PATL. This method takes advantage of the adjustable radiation angle of the phased array antenna to scan the surveillance region in turns.
