Human activities are inherently translation invariant and hierarchical. Human activity recognition (HAR), a field that has garnered a lot of attention in recent years due to its high demand in various application domains, makes use of time-series sensor data to infer activities. In this paper, a deep convolutional neural network (convnet) is proposed to perform efficient and effective HAR using...

Recent advancements in depth video sensors technologies have made human activity recognition (HAR) realizable for elderly monitoring applications. Although conventional HAR utilizes RGB video sensors, HAR could be greatly improved with depth video sensors which produce depth or distance information. In this paper, a depth-based life logging HAR system is designed to recognize the daily activiti...

BACKGROUND AND OBJECTIVES Hyperacute rejection (HAR) is a major obstacle to successful xenotransplantation of vascularized organs. This study was conducted to observe the effect of hemolysis of perfused human whole blood on pig heart function, and determine the major risk factors for preservation of xenoperfused cardiac function using ex-vivo pig to human xenogeneic cardiac perfusion model. M...

One of the great chemists of the 20th century died on November 9, 2011. H. Gobind Khorana, a founder of what we now call chemical biology and a pioneer at the dawn of the age of molecular biology, was 89 (see Image 1). Gobind was a creative and insightful chemist, with many landmark achievements to his credit, including the first practical synthesis of nucleotides and coenzymes in the mid-1950s...
