An Impedance Detection Circuit for Applications in a Portable Biosensor System    (01/02/2016)

An Impedance Detection Circuit for Applications in a Portable Biosensor System (Accepted for the coming International Symposium on Circuits and Systems 2016 (http://iscas2016.org/).) Abstract— As the world’s population ages, healthcare costs become heavy burdens worldwide. Portable point-of-care diagnostic devices, such as glucose meters, can significantly reduce the costs associated with patient care. There are many of small biological molecules present in biological samples which are of interest in healthcare applications. In this paper, a simple low-cost impedance detection circuit has been designed to detect different biomolecules such as DNA, proteins and other metabolites. In particular, the impedance across an electrode will change due to the binding of target biomolecules and gold nanoparticles.  Experimental results show that the device can measure impedance changes with accuracy in the range of ±3%.

Implementation of Efficient Parallel Discrete Cosine Transform Using Stochastic Logic    (22/01/2016)

Implementation of Efficient Parallel Discrete Cosine Transform Using Stochastic Logic
This paper is accepted for the coming International Symposium on Circuits and Systems 2016 (http://iscas2016.org/)
 Abstract—This paper provides a new scheme for the VLSI implementation of a parallel Discrete Cosine Transform (DCT) using stochastic logic. Stochastic computation is a number representation, which can carry out complex computations with very low hardware cost. However, the delay of data output is proportional to the length of serial sequence. We provide a new area-saving parallel DCT design to improve the system throughput by using our proposed stochastic OR-adder and OR-AND-adder. Results show the proposed parallel stochastic DCT can meet the requirement of image processing while maintaining a 5% performance difference compared to the traditional DCT implementation. Our synthesized chip design using the TSMC CMOS 130nm technology also shows that the proposed parallel stochastic DCT is at least 10 times more efficient in area and delay than that of the traditional DCT and the serial stochastic DCT.

Area-Efficient Partial-Clique-Energy MRF Pair Design with Ultra-Low Supply Voltage    (22/01/2016)

Area-Efficient Partial-Clique-Energy MRF Pair Design with Ultra-Low Supply Voltage
This paper is accepted for the coming International Symposium on Circuits and Systems 2016 (http://iscas2016.org/)
 Abstract—As the size of CMOS devices continues to scale down, the reliability of circuits becomes one of main challenges in low supply voltage designs. Markov Random Field (MRF) circuits, a probabilistic-based approach, can achieve higher noise immunity compared to traditional designs under conditions of ultra-low supply voltage and low threshold voltage. However, the basic MRF elements have complex structures and become a stringent factor that limits MRF-based VLSI design. In this paper, we provide a partial-clique-energy MRF (PMRF) design method, trading off the noise immunity for area efficiency. We then propose an Enhanced PMRF (EPMRF)-pair for multi-level and multi-function joint PMRF designs. The main idea is to use the joint clique energy of two complementary partial clique energies to make up performance losses. The measurement results show that, the proposed EPMRF pair can operate at 0.25 V with 10-4 dB output noise power with 5.6 dB input signal-noise ratio (SNR). With the 130 nm CMOS technology, the chip of our EPMRF based carrylook-ahead adder achieves 29% area-saving and 55% energysaving compared to existing ultra-low supply voltage fault tolerant designs.   (Full paper).

Design of a Thermoacoustic Sensor for Low Intensity Ultrasound Measurements Based on an Artificial Neural Network    (19/08/2015)

By Jida Xing and Jie Chen  Was published in Sensors, 2015  "A novel two-layer thermoacoustic sensor based on an artificial neural network is described and investigated in this paper. The structure design improvement enables the sensor to reduce its measurement time from 20 s to 12 s. The artificial neural network algorithm is integrated in order to compensate for the influence of the temperature drifts, adapting the sensor for a range of ambient temperatures, and providing an accurate and consistent measurement of the ultrasound intensities. The experimental result show that the compensation provided by the artificial neural network reduced the temperature drift errors from more than 15% to 1%. The final results show that the new sensor achieves an average error of 1.31mW/cm2 over 18 measurement samples. The new sensor design is a low-cost alternative method that can provide rapid ultrasound intensity measurements without any complex set-up procedure. Although the radiation force balance is the golden standard method with minimal measurement error, the application of the technique is limited by the requirements of experience in regards to equipment set-up and operation. In addition, measurement accuracy is affected by background vibrations, which in turn limits its application in biology laboratories. The new thermoacoustic sensor design is an easy-to-operate alternative method for rapidly measuring low ultrasound intens [ ... ]

Killam Professorship    (22/06/2015)

(Edmonton) Jie Chen was thrilled to be named one of five University of Alberta recipients of a 2015 Killam Annual Professorship—less because of the personal recognition, and more because of the opportunities it opens up. “This recognition can bring me to the next level of excellence,” he said. A Killam can help open doors to further research collaborations, international awards, and funding opportunities, observed Chen. He takes particular pride in the fact that the Killam reflects all aspects of professorship. “The Killam Professorship is like a triathlon,” he said, “because it looks at your teaching, your research, and your community service.” The award represents a validation of Chen’s decision a decade ago to leave an Ivy League posting at Brown University for a fresh start at the U of A. “At the time, I was looking to work in a more multi-disciplinary area—more towards biomedical,” he said. “The National Research Council and its National Institute for Nanotechnology (NINT—a world-class research facility operated jointly by the U of A and the NRC) were recruiting people worldwide.” The opportunities for interdisciplinary collaboration began virtually the moment Chen arrived on campus. At an introductory workshop, Chen and other new faculty members were exploring ways to motivate students to study subjects they don’t like. “One of the other professors said, ‘I hate circuit design.’ So I stood up in front of my peers, an [ ... ]

Treating Cancer Stem Cells and Cancer Metastasis Using Glucose-coated Gold Nanoparticles    (24/01/2015)

 "Treating Cancer Stem Cells and Cancer Metastasis Using Glucose-coated Gold Nanoparticles", to be for published in International Journal of Nanomedicine. Abstract:  Cancer ranks among the leading causes of human mortality. Cancer becomes intractable when it spreads from the primary tumor site to various organs (such as bone, lung, liver, and brain). Unlike solid tumor cells, cancer stem cells and metastatic cancer cells grow in a non-attached (suspension) form when moving from their source to other locations in the body. Due to the nature of non-attached growth, metastasis is often first detected in the circulatory systems, for instance in a lymph node near the primary tumor. Cancer research over the past several decades has primarily focused on treating solid tumors, but targeted therapy to treat cancer stem cells and cancer metastasis has yet to be developed. Because cancers undergo faster metabolism and consume more glucose than normal cells, glucose was chosen in this study as a reagent to target cancer cells. In particular, by covalently binding gold nanoparticles (GNPs) with thio-PEG (Polyethylene glycol) and thio-glucose, the resulting functionalized GNPs (Glu-GNPs) were created for targeted treatment of cancer metastasis and cancer stem cells. Suspension cancer cell THP-1 (human monocytic cell line derived from acute monocytic leukemia patients) was selected because it has properties similar to cancer stem cells and has been used as a metastatic cance [ ... ]
