A note on twisted discrete singular Radon transforms [PDF]
Mathematical Research Letters, 2010 In this paper we consider three types of discrete operators stemming from singular Radon transforms. We first extend an $\ell^p$ result for translation invariant discrete singular Radon transforms to a class of twisted operators including an additional oscillatory component, via a simple method of descent argument. Second, we note an $\ell^2$ bound for

ChemBioChem, Volume 27, Issue 11, 15 June 2026.Polycomb (Pc), a core component of Polycomb Repressive Complex 1 (PRC1), is largely intrinsically disordered yet forms buffer‐ and concentration‐dependent higher‐order assemblies. Integrative biophysical analysis and cryo‐electron microscopy reveal dynamic, heterogeneous oligomers, whereas AlphaFold modeling suggests that structural organization is ...

Fast computation of two-dimensional discrete cosine transforms using fast discrete radon transform
, 1991 A new fast algorithm is presented for computing the two-dimensional discrete cosine transform (2D DCT) using the fast discrete Radon transform. The algorithm has the lowest number of multiplications compared with other algorithms.

Advanced Science, Volume 13, Issue 34, 19 June 2026.INB3P is a multimodal framework for blood–brain barrier‐penetrating peptide prediction under extreme data scarcity and class imbalance. By combining physicochemical‐guided augmentation, sequence–structure co‐attention, and imbalance‐aware optimization, it improves predictive performance and interpretability.

Chebyshev Inversion of the Radon Transform
, 2016 In its two-dimensional form, the Radon transform of an image (function) is a collection of projections of the image which are parameterized by a set of angles (from the positive x-axis) and distances from the origin.

Reconstructing a set from its subset sums: $2$-torsion-free groups
Discrete AnalysisA famous conjecture in graph theory, asked by Kelly (1957) and Ulam (1960) and now known as the reconstruction conjecture, states that every graph with $n\geq 3$ vertices is determined up to isomorphism by the multiset of induced subgraphs with $n-1 ...
