We introduce the first visual dataset of fast foods with a total of 4,545 still images, 606 stereo pairs, 303 360° videos for structure from motion, and 27 privacy-preserving videos of eating events of volunteers. This work was motivated by research on fast food recognition for dietary assessment. The data was collected by obtaining three instances(More)
As a safe and feasible alternative to enriching and enhancing traditional surgical training, virtual-reality-based surgical simulators have been investigated for a long time. But it is still a challenge for researchers to accurately depict the behavior of human tissue without losing the flexibility of simulation. In this paper, we propose an improved scheme(More)
We propose a maximal figure-of-merit (MFoM)-learning approach for robust classifier design, which directly optimizes performance metrics of interest for different target classifiers. The proposed approach, embedding the decision functions of classifiers and performance metrics into an overall training objective, learns the parameters of classifiers in a(More)
The human gastrointestinal tract harbors a complex and abundant microbial community that can reach levels as high as 1013–1014 microorganisms in the colon. These microorganisms are essential to a host’s well-being in terms of nutrition and mucosa immunity. However, numerous studies have also implicated members of the colonic microbiota in the development of(More)
Recent reports have suggested that multiple factors such as host genetics, environment and diet can promote the progression of healthy mucosa towards sporadic colorectal carcinoma. Accumulating evidence has additionally associated intestinal bacteria with disease initiation and progression. In order to examine and analyze the composition of gut microbiota(More)
This paper presents a new class of dual-, tri- and quad-band BPF by using proposed open stub-loaded shorted stepped-impedance resonator (OSLSSIR). The OSLSSIR consists of a two-end-shorted three-section stepped-impedance resistor (SIR) with two identical open stubs loaded at its impedance junctions. Two 50- Ω tapped lines are directly connected to(More)
According to numbers of music cognitive experiments, moods or emotions in music could be categorical. Since mood classifications are commonly used to structure the large collections of music available on the Web, automatic discrimination between mood taxonomy of Chinese traditional music and Western classical music would be a valuable addition to music(More)
Although epithelial barrier dysfunction in the gut has been extensively reported in ulcerative colitis (UC), the pathogenesis of this disease is not completely understood. In the present study, we investigated the role of miR-21 in regulating intestinal epithelial barrier function in UC. Colonic biopsies were obtained from 30 chronic UC patients and 30(More)
