Abstract The Vettore–Bove normal fault system in central Italy ruptured during the 2016 M W 6.5 Norcia earthquake causing extensive surface faulting. At Pian Grande di Castelluccio hanging wall basin, along southern section of mainshock, we performed a high‐resolution seismic reflection/refraction experiment aimed at (a) imaging shallow pattern system, and (b) reconstructing architecture contin...

We show that a metal-dielectric-metal structure can function as a negative refraction lens for surface plasmon waves on a metal surface. The structure is uniform with respect to a plane of incidence and operates at the optical frequency range. Using three-dimensional finite-difference time-domain simulations, we demonstrate the imaging operation of the structure with realistic material paramete...

Two ultrasonic techniques for reconstructing the internal temperature distribution in metal bodies-timeof-flight tomography and dimensional resonance profiling-are described. An analysis of the tomographic reconstruction of temperature (including ray refraction effects) in a cylindrical body is presented together with initial experimental results. Dimensional resonance profiling is a new techni...

purpose: to investigate the effects of surface ablation excimer surgery on higher-order aberrations and to assess the safety and efficacy of wavefront-guided surface ablation excimer surgery in patients with hyperopia and hyperopic astigmatism. methods: in this analytical & descriptive study, wavefront-guided surface ablation excimer surgery was performed in 58 eyes of 31 patients with hyperopi...

We consider the problem of radiative transfer in stellar atmospheres where the index of refraction departs from unity and is a function of density and temperature. We present modified Feautrier and Lambda-iteration methods to solve the equation of radiative transfer with refraction in a plane parallel atmosphere. These methods are general and can be used in any problem with 1-D geometry where t...

Abstract. In semi-arid Chile, rock glaciers cover more surface area than and are potentially important water reserves. To understand their current future hydrological role, it is necessary to characterize internal structure (e.g. boundaries ice, air, content). this study, we present the results interpretations of profiles electrical resistivity refraction seismic tomography collected on two con...
