Varieties of planes on intersections of three quadrics [PDF]
arXiv, 2019 We study the geometry of spaces of planes on smooth complete intersections of three quadrics, with a view toward rationality questions.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

TEACHING BASIC ELEMENTS IN DESCRIPTIVE GEOMETRY – LINE INTERSECTING A PLANE
Journal of Industrial Design and Engineering GraphicsThe paper presents applications developed for teaching descriptive geometry. The aim of the applications presented is the understanding of the basic elements of the descriptive geometry – the relative positions of a straight line and a plane and they ...

Gluing two affine Yangians of 𝔤𝔩1
Journal of High Energy Physics, 2019 We construct a four-parameter family of affine Yangian algebras by gluing two copies of the affine Yangian of 𝔤𝔩1. Our construction allows for gluing operators with arbitrary (integer or half integer) conformal dimension and arbitrary (bosonic or ...

Topological equivalence of finitely determined real analytic plane-to-plane map-germs [PDF]
arXiv, 2009 Generic smooth plane-to-plane map germs are topologically equivalent to cones of mappings of the circle. We carry out a complete topological classification of smooth stable mappings of the circle and show how this classification leads, via the result mentioned above, to a topological classification of finitely determined real analytic plane-to-plane ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study quantitatively evaluates bladder changes and their dosimetric impact during the on‐couch adaptive process on a commercial CBCT‐based online adaptive radiotherapy (CT‐gART) platform. Methods Data from 183 fractions of ten patients receiving online ART for pelvic cancers were analyzed retrospectively.

The Grushin plane and quasiconformal Jacobians [PDF]
arXiv, 2011 We construct a quasiconformal map from the Grushin plane to the Euclidean plane. Then, we generalize the Grushin plane slightly and explain how the Grushin plane can serve as an intermediary in dealing with quasiconformal maps on Euclidean spaces. In particular, we construct a family of quasiconformal embeddings of the Euclidean plane into larger ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose A new workflow was investigated for Elekta Unity MR‐Linac by removing the computed tomography (CT)‐simulation step and using diagnostic CT (DCT) for reference plan generation. Materials and methods Ten patients with ultra‐hypofractionated prostate cancer treated with magnetic resonance imaging (MRI)‐guided adaptive radiotherapy were ...

GEOMETRY – AN IMPORTANT MEANS OF EDUCATION IN THE CIVILISATION SCOPE
Journal of Industrial Design and Engineering Graphics, 2017 Geometry (from the Greek: γεωμετρία; geo = earth, metria = measure) is a genuine science, rooted in mathematics, which studies the plane and spatial forms of bodies from the objective or conceptual reality and the nature of the relationship that exists ...
