A new model for turbulence-corrupted imagery is proposed based on the theory of optimal mass transport. By describing the relationship between photon density and the phase of the traveling wave, and combining it with a least action principle, the model suggests a new class of methods for approximately recovering the solution of the photon density flow created by a turbulent atmosphere. Both coherent and incoherent imagery are used to validate and compare the model to other methods typically used to describe this type of data. Given its superior performance in describing experimental data, the new model suggests new algorithms for a variety of atmospheric imaging and wave propagation applications.
Careful internal defect coverage is important for a well vascularised internal base for the transplant in reconstructive nasal surgery. Secondary healing of intranasal wounds often results in nostril contracture and scar stenosis. The choice of methods for surgical coverage depends on the location of the defect and the condition of surrounding elements. For example, the double-stemmed "pot handle" flap is suitable for small defects of the internal lining of the nasal lobule. The septal mucosa flap can be used for larger and more complex defects of the internal nasal lining. Using composite skin and cartilage grafts from the ear, three-layered nasal defects can be treated in a variety of ways. The turn-in flap is a tilt flap and is very versatile for the treatment of inner defects of the lower nasal half.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
