This paper presents a wildfire smoke detection method based on a spatiotemporal bag-of-features (BoF) and a random forest classifier. First, candidate blocks are detected using key-frame differences and non-parametric color models to reduce the computation time. Subsequently, spatiotemporal three-dimensional (3D) volumes are built by combining the candidate(More)
Primary squamous cell carcinomas arising from the thyroid gland (SCCTh) is extremely rare diseases, which have never been fully studied. Thus, we performed a systematic review and individual participant data meta-analysis of published SCCTh cases, to understand the clinical characteristics and to identify the prognostic factors of primary SCCTh.

OBJECTIVES Although biofilms have been implicated in poor prognosis after endoscopic sinus surgery (ESS), traditional methods detecting biofilm such as scanning electron microscope and confocal scanning laser microscope were rarely used in the practice. The aims of this study was to determine whether the presence or absence of a biofilm detected by(More)
