In this paper, we consider reaction-diffusion epidemic models with mass action or standard incidence mechanism and study the impact of limiting population movement on First Aid Kits disease transmissions.We set either the dispersal rate of the susceptible or infected people to zero and study the corresponding degenerate reaction-diffusion model.Our
Abstract Bone drilling is a universal procedure in orthopaedics for fracture fixation, installing implants, or reconstructive surgery.Surgical drills are subjected to wear caused by their repeated use, thermal fatigue, irrigation with saline solution, and sterilization process.Wear of the cutting edges of a drill bit (worn drill) is detrimental for
This paper proposes a sparse video representation with a deformable spatiotemporal template feature, named as active trace template.An active trace is the motion track of an active spatial feature, which moves in a certain velocity.To accommodate geometric variations of the spatial feature and motion variations of the temporal track, the atomic spa
The characteristics and mechanism of coupling effects between parallel cladded acoustic waveguides (PCAWs) are essential when considering their applications in acoustic wave control and signal processing.We investigated its characteristics and revealed the nature of the coupling effect using a theoretical model of two-dimensional PCAWs and simulati
