Feasibility of a method for low contrast CT image quality assessment using difference detail curves for abdominal scans.
Sommer C, Özden I, Weyland MS, Duran C, Lutters G, Scheidegger S. Sommer C, et al. Z Med Phys. 2022 May;32(2):209-217. doi: 10.1016/j.zemedi.2022.01.001. Epub 2022 Feb 17. Z Med Phys. 2022. PMID: 35184974 Free PMC article. German.
This work describes a measurement method for assessing dose-related image-quality of CT scans based on the difference detail curve (DDC) method, and showcases its use in a low contrast setting. The method is based on a phantom consisting of elliptical slices of diff …

Pariah moonshine.
Duncan JFR, Mertens MH, Ono K. Duncan JFR, et al. Nat Commun. 2017 Sep 22;8(1):670. doi: 10.1038/s41467-017-00660-y. Nat Commun. 2017. PMID: 28935903 Free PMC article.
Here we report on a solution to this problem that reveals the O'Nan pariah group as a source of hidden symmetry in quadratic forms and elliptic curves. Using this we prove congruences for class numbers, and Selmer groups and Tate-Shafarevich groups of elliptic …

Higher-rank zeta functions for elliptic curves.
Weng L, Zagier D. Weng L, et al. Proc Natl Acad Sci U S A. 2020 Mar 3;117(9):4546-4558. doi: 10.1073/pnas.1912023117. Epub 2020 Feb 18. Proc Natl Acad Sci U S A. 2020. PMID: 32071252 Free PMC article.
In earlier work by L.W., a nonabelian zeta function was defined for any smooth curve X over a finite field [Formula: see text] and any integer [Formula: see text] by[Formula: see text]where the sum is over isomorphism classes of [Formula: see text]-rational semistable vect …

ELLIPTIC CURVES ARISING FROM THE TRIANGULAR NUMBERS.
Juyal A, Kumar SD, Moody D. Juyal A, et al. Integers. 2019;19:A10. Integers. 2019. PMID: 31275081 Free PMC article.
We study the Legendre family of elliptic curves E(t) : y (2) = x(x - 1)(x - delta (t) ), parametrized by triangular numbers delta (t) = t(t + 1)/2. ...We also produce some infinite subfamilies whose Mordell-Weil rank is positive, and find high rank curves fro …

Characteristic Mapping for Ellipse Detection Acceleration.
Jia Q, Fan X, Yang Y, Liu X, Luo Z, Wang Q, Zhou X, Latecki LJ. Jia Q, et al. IEEE Trans Image Process. 2023;32:2568-2579. doi: 10.1109/TIP.2023.3268563. Epub 2023 May 5. IEEE Trans Image Process. 2023. PMID: 37093727
It is challenging to characterize the intrinsic geometry of high-degree algebraic curves with lower-degree algebraic curves. The reduction in the curve's degree implies lower computation costs, which is crucial for various practical computer vision sys …

Isogenies on twisted Hessian curves.
Perez FL, Dang T, Fouotsa E, Moody D. Perez FL, et al. J Math Cryptol. 2021;15(1):10.1515/jmc-2020-0037. doi: 10.1515/jmc-2020-0037. J Math Cryptol. 2021. PMID: 34322179 Free PMC article.
Elliptic curves are typically defined by Weierstrass equations. Given a kernel, the well-known Velu's formula shows how to explicitly write down an isogeny between Weierstrass curves. ...Previous papers have shown some isogeny formulas for (twisted) Edwards, …

High rank elliptic curves with torsion /4.
Khoshnam F, Moody D. Khoshnam F, et al. Integers. 2016;17:A70. Integers. 2016. PMID: 28769739 Free PMC article.
Working over the field (t), Kihara constructed an elliptic curve with torsion group /4 and five independent rational points, showing the rank is at least five. Following his approach, we give a new infinite family of elliptic curves with torsion group …

We define objective Eulerian Coherent Structures (OECSs) in two-dimensional, non-autonomous dynamical systems as the instantaneously most influential material curves. Specifically, OECSs are stationary curves of the averaged instantaneous material stretching-rate or …
