Local region-based active contour models (ACMs) can effectively segment images corrupted by intensity inhomogeneity, however, they always converge to local minimum and are sensitive to the initial position of contour.In this paper, a novel fuzzy ACM is proposed to tackle these problems.In order to deal with intensity inhomogeneity, the fuzzy local
IntroductionThe rates of gonorrhea and chlamydia have been increasing in the years preceding the COVID19 pandemic.Because most gonorrhea and chlamydia infections are located in the oropharynx and rectum for men who have sex with men (MSM), and because at-home self-collected swabs for these infections are not licensed by Health Canada or the United
Internal gravity waves are propagating disturbances in stably stratified fluids, and can transport momentum and energy over large spatial extents.From a fundamental viewpoint, internal waves are interesting due to the nature of their dispersion relation, and their linear dynamics are reasonably well-understood.From an oceanographic viewpoint, a qua
One of the largest and least documented populations of dugongs (Dugong dugon) resides in the coastal waters of the United Arab Emirates, and waters surrounding Saudi Arabia, Bahrain, and Qatar.The archaeological record of dugongs in the Gulf Panel Kits Region is abundant, but little is known about their fossil record in the region.Here we report an
