When implementing new features into a software system, developers may duplicate several lines of code to reuse some existing code segments. This action creates code clones in the software system. The literature has documented different types of code clone (e.g., Type-1, Type-2, and Type-3). Once created, code clones evolve as they are modified during both(More)
Homogeneous assays possess important advantages that no washing or physical separation is required, contributing to robust protocols and easy implementation which ensures potential point-of-care applications. Optimizing the detection strategy to reduce the number of reagents used and simplify the detection device is desirable. A method of homogeneous(More)
Copy and paste activities create clone groups in software systems. The evolution of a clone group across the history of a software system is termed as clone genealogy. During the evolution of a clone group, developers may change the location of the code fragments in the clone group. The type of the clone group may also change (e.g., from Type-1 to Type-2).(More)
Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory condition. Psychological stress has been postulated to affect the clinical symptoms and recurrence of IBD. The exact molecular mechanisms are not fully understood. In the present study, we demonstrate that psychological stress promotes neutrophil infiltration into colon tissues in dextran(More)
Hardware implementation of human detection is a challenging task for embedded designs. This paper presents a real-time image-based field-programmable gate array (FPGA) implementation of human detection. Our implementation is based on the histograms of oriented gradients (HOG) feature and linear support vector machine (SVM) classifier. The novelty of this(More)
Rapid separation of white blood cells from whole blood sample is often required for their subsequent analyses of functions and phenotypes, and many advances have been made in this field. However, most current microfiltration-based cell separation microfluidic chips still suffer from low-throughput and membrane clogging. This paper reports on a(More)
Solar energy absorption coating CoCuMnOx was prepared by co-precipitation method and applied to photodegrade multi- component VOCs including toluene, ethyl acetate and acetone under visible light irradiation. The photocatalytic oxidation performance of toluene, ethyl acetate and acetone was analyzed and reaction kinetics of VOCs were investigated(More)
