Corneal Surface Disease Topology
International Ophthalmology Clinics, 1998The specific morphology and distribution of corneal surface lesions may point toward a specific diagnosis and pathogenesis in individual cases (see Fig 1). Staining lesions may be fine (e.g., staphylococcal) or punctate (e.g., keratitis sicca). The size and appearance of staining and nonstaining lesions of the epithelium and subepithelial cornea may be

Topological Surface Acoustic Waves
Physical Review Applied, 2021Topological materials for classical waves, e.g., electromagnetic and acoustic waves, have attracted growing interest, mainly due to the robustness, low loss, and new artificial degree of freedom conferred by their boundaries. Surface acoustic waves (SAWs), as widely used information carriers of microdevice relevance, are ubiquitous in today's wireless ...

SURFACE TOPOLOGY USING RUTHERFORD BACKSCATTERING
Nuclear Instruments and Methods, 1980Abstract In order to investigate roughness, we have scattered protons in the vicinity of 400 keV off a variety of surfaces. The energy spectra were measured using surface barrier detectors as a function of incident and emergent angle. Spectra have been calculated theoretically, simulating the particle trajectories using both analytical and computer ...

Topological Approach to Quantum Surfaces
Communications in Mathematical Physics, 1999A topological approach to quantisation of closed surfaces is presented. This is done by imposing the following ``minimal'' requirements for a quantisation \(R\) of a closed Riemann surface \(\Sigma\) of genus \(g\geq 2\): \(R\) is a unital \(C^*\)-algebra, both \(R\) and \(C(\Sigma)\) are fibres in a continuous family of \(C^*\)-algebras over a path ...
