BACKGROUND & AIMS AIM2 plays an important role in innate immunity, but its role in regulating the immune response to hepatitis B virus (HBV) is unknown. We hypothesized that AIM2 expression is positively correlated with HBV-mediated inflammation in patients with HBV-associated glomerulonephritis (HBV-GN), potentiating inflammation and leading to renal(More)
Although the radiation force balance is the gold standard for measuring ultrasound intensity, it cannot be used for real-time monitoring in certain settings, for example, bioreactors or in the clinic to measure ultrasound intensities during treatment. Foreseeing these needs, we propose a close-proximity thermoacoustic sensor. In this article, we describe(More)
Generating renewable energy while sequestering CO2 using algae has recently attracted significant research attention, mostly directing towards biological methods such as systems biology, genetic engineering and bio-refining for optimizing algae strains. Other approaches focus on chemical screening to adjust culture conditions or culture media. We report for(More)
Riskless interest rate and volatility are two important variables in option pricing model, but are hard to be estimated precisely. The concept of fuzziness is used to describe these variables in this paper. We apply fuzzy set theory to the American put option valuation and extend the fuzzy option pricing model by introducing riskless interest rate and(More)
An automatic image processing method is proposed to extract vocal fold vibrations from high-speed digital imaging. Extracted regular vocal fold vibrations contribute to periodic voices, and irregular vocal fold vibrations contribute to aperiodic voices. The effects of image resolutions are investigated. This study combines the features of both image and(More)
Over the past decades, we have witnessed the growth demands of portable lab-on-chip biosensors. These lab-on-chip devices are mostly powered by battery, and intelligent power management systems are required to provide supply voltage for different functional units on biosensors (e.g. a microfluidic control system might require higher voltage than the rest(More)
In this paper, a simple and adaptive thermoacoustic sensor was designed to measure Low Intensity Pulsed Ultrasound (LIPUS). Compared to other thermoacoustic sensor designs, our novelty lies in (i) integrating an ultrasound medium layer during the measurement to simplify the complicated set-up procedures and (ii) taking the effect of ambient temperatures(More)
