—With the rise of many-core chips that require substantial bandwidth from the network on chip (NoC), integrated photonic links have been investigated as a promising alternative to traditional electrical interconnects. While numerous opto-electronic NoCs have been proposed, evaluations of photonic architectures have thus-far had to use a number of(More)
This paper presents photonic devices with 3 dB/cm waveguide loss fabricated in an existing commercial electronic 45 nm SOI-CMOS foundry process. By utilizing existing front-end fabrication processes the photonic devices are monolithically integrated with electronics in the same physical device layer as transistors achieving 4 ps logic stage delay, without(More)
The performance of future manycore processors will only scale with the number of integrated cores if there is a corresponding increase in memory bandwidth. Projected scaling of electrical DRAM architectures appears unlikely to suffice, being constrained by processor and DRAM pin-bandwidth density and by total DRAM chip power, including off-chip signaling,(More)
The goal of high level event classification from videos is to assign a single, high level event label to each query video. Traditional approaches represent each video as a set of low level features and encode it into a fixed length feature vector (e.g. Bag-of-Words), which leave a big gap between low level visual features and high level events. Our paper(More)

—Integrated photonic interconnects have emerged recently as a potential solution for relieving on-chip and chip-to-chip bandwidth bottlenecks for next-generation many-core processors. To help bridge the gap between device and cir-cuit/system designers, and aid in understanding of inherent photonic link tradeoffs, we present a set of link component models(More)
Extrahepatic cholangiocarcinoma (EHCC) is a refractory malignancy with poor prognosis due to its early invasion, metastasis and recurrence after operation. Therefore, understanding the mechanisms of invasion and metastasis is the key to the development of new and effective therapeutic strategies for EHCC. In the present study we demonstrated that miR-221(More)
Event recognition has been an important topic in computer vision research due to its many applications. However , most of the work has focused on videos taken from a fixed camera, known environments and basic events. Here, we focus on classification of unconstrained, web videos into much higher level activities. We follow the approach of constructing fixed(More)
