The impact of long‐term nucleos(t)ide analogs treatment on host metabolism is a concern. Hence, we conducted this study to compare the effect of entecavir (ETV) and tenofovir disoproxil fumarate (TDF) on metabolic parameters among chronic hepatitis B (CHB) patients. In this real‐life retrospective study, 2030 CHB outpatients treated with ETV or TDF at Nanfang Hospital, China, were included. For treatment‐naïve...
Our earlier work on support vector machines (SVM) and ultrasonic flaw detection algorithms demonstrated i) highly accurate classifier performance and ii) the feasibility of the algorithm for real-time implementation on low-cost embedded systems with graphical processing units (GPU) and CUDA library (a parallel computing platform and programming model) support. This works extends the implementation...
This study investigates the performance of different hardware platforms and development frameworks for efficient realization of an ultrasonic flaw detection algorithm based on the Support Vector Machine (SVM) classifier. The proposed algorithm is based on subband decomposition of ultrasonic signals followed by classification with a trained SVM model that uses subband filter outputs as feature inputs...
In this work, we investigate the hardware implementation of Support Vector Machine (SVM) prediction on an FPGA platform for industrial ultrasound applications. Specifically, SVM is used as classifier for identifying ultrasonic A-scan signals as signals with flaw or signals without flaw. Hardware acceleration using FPGA is the main theme of the presented work. The architecture used to implement the...
We demonstrate a label-free cell analyzer with high throughput and single-cell resolution based on optofluidic time-stretch microscopy. It is capable of acquiring images of cells at a throughput beyond 10,000 cells/s with a spatial resolution of 780 nm in a label-free manner, allowing for statistical analysis of the cells' phenotypes from the images via machine learning methods. Moreover, using compressed...
The development of reliable, sustainable, and economical sources of alternative fuels to petroleum is required to tackle the global energy crisis. One such alternative is microalgal biofuel, which is expected to play a key role in reducing the detrimental effects of global warming as microalgae absorb atmospheric CO2 via photosynthesis. Unfortunately, conventional analytical methods only provide population‐averaged...
