Inversion-Based Deblending in Common Midpoint Domain Using Time Domain High-Resolution Radon

open access: yesAlgorithms
We implement an inversion-based deblending method in the common midpoint gathers (CMP) as an alternative to the standard common receiver gather (CRG) domain methods.

The Radon transform of Boehmians [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
The Radon transform, which enables one to reconstruct a function of N N variables from the knowledge of its integrals over all hyperplanes of dimension N − 1 N - 1 , has been extended to Schwartz distributions by several people including Gelfand, Graev, and Vilenkin, who extended it to tempered

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

open access: yesAdvanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Next-Generation Secure and Reversible Watermarking for Medical Images using Hybrid Radon-Slantlet Transform

open access: yesResults in Engineering
This research article proposes a security-enhanced watermarking method for medical images using the Radon and Slantlet transforms. The first step involves transforming the cover image from the spatial domain to the Radon domain.

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

Spherical Radon Transform [PDF]

open access: yesGeophysical Journal International, 1988
SUMMARY Spherical Radon transform is discussed in this paper. We provide a formulism that allows the distribution of a function from a complete set of integral values along great circles on the spherical surface to be obtained. This means that the integral transform and its inverse transform are obtained.
