Rhythms in longitudinal thalamic recordings are linked to seizure risk
Epilepsia, EarlyView.Abstract Objective Seizure unpredictability remains a major clinical challenge for people with epilepsy. Previous works have shown that seizure risk is associated with circadian and multi‐day cycles in both brain and physiological signals. However, it remains unclear whether neural activity from deep brain structures such as the anterior nucleus of the

The Radon and Hilbert transforms and their applications to atmospheric waves
Atmospheric Science LettersThe Radon and Hilbert transform and their applications to convectively coupled waves (CCWs) are reviewed. The Hilbert Transform is used to compute the wave envelope, whereas the Radon transform is used to estimate the phase and group velocities of CCWs ...

Spherical Radon Transform and Related Wavelet Transforms
Applied and Computational Harmonic Analysis, 1998 The author introduces the continuous wavelet transform associated with the spherical Radon transform \(Rf\) on the \(n\)-dimensional unit sphere \({\mathbf S}^n\), \(n\geq 2\), where \(f\in L^p({\mathbf S}^n)\) or \(f\in C({\mathbf S}^n)\). Explicit wavelet representations for the spherical Radon transform \(R\) and for its inverse transform \(R^{-1}\)

Frontiers in EEG as a tool for the management of pediatric epilepsy: Past, present, and future
Epilepsia Open, EarlyView.Abstract Electroencephalography (EEG) has evolved into an indispensable tool in pediatric epilepsy, fundamentally transforming the diagnosis, classification, and management of this condition. This review chronicles the historical journey of EEG from its groundbreaking inception to its current pivotal role in delineating distinct pediatric epilepsy ...

The Radon transform on the Heisenberg group and the transversal Radon transform
Journal of Functional Analysis, 2012 The notion of the Radon transform on the Heisenberg group was introduced by R. Strichartz and inspired by D. Geller and E.M. Stein's related work. The more general transversal Radon transform integrates functions on the m-dimensional real Euclidean space over hyperplanes meeting the last coordinate axis.
