Atrial fibrillation (AF) is the most common supraventricular tachyarrhythmia and its prevalence is expected to increase with the aging population. However, the mechanisms AF initiation, maintenance and termination are not completely understood. The surface electrocardiogram (ECG) characteristics are a direct reflection of pathophysiologic events in the atria and can be...
As we move into deeper sub-micron technologies, the complexity of pushing the circuit performance further is becoming an important obstacle. To achieve better performance, there is an increasing need for collaboration of higher level (e.g. microarchitecture-level) and circuit level optimizations. Traditionally for a computer system, applications lie at the top...
Process scaling has enabled the production of integrated circuits with millions of transistors. System-on-a-Chip becomes feasible as more functionalities can be packed into a single chip. As the human brain power is limited, the design process of such sophisticated systems should be automated in order to meet the stringent design...
The growing technological industry is demanding the development of powerful and smaller devices. Dielectric thin-films can play an important role to help push towards achieving these goals. However, their advantage of high-quality material and low material costs compared to bulk can only be achieved with consideration of the technique, conditions,...
Visual object tracking, i.e. consistently inferring the motion of a desired target from image sequences, is a must-have component to bridge low-level image processing techniques and high-level video content analysis. This has been an active and fruitful research topic in the computer vision community for decades due to both its...
Integrated circuits have been continuously scaled to increase speed and integration density as a means to improve the performance or pack more functionality. However, an extremely enormous amount of effort is needed to further scale the dimensions in deep submicron technologies. As technology scaling is slowing down and design complexity...

As manufacturing technology moves toward fundamental limits of silicon CMOS processing, it is increasingly important to utilize the full potential of available transistors and interconnects. While manufacturing technology faces fundamental limits inherent in physical laws or material properties, design and verification technology faces fundamental limitations inherent in the computational intractability...
Leakage currents limit the operation of high performance type II InAs/GaSb superlattice photodiode technology. Surface leakage current becomes a dominant, limiting factor to the ideal performance of a photodiode, especially at the scale of a focal plane array pixel (< 25 µm), and must be addressed. A reduction of the...
Multi-hop wireless networks hold promise for increasing network capacity, lowering power requirements, and improving coverage over traditional cellular networks. However, their widespread adoption is hampered by challenges that include: 1) unreliable and complex routing protocols due to the transient nature of wireless nodes, 2) difficulties in guaranteeing quality of service...
