Вестник Дагестанского государственного технического университета: Технические науки, 2023 Objective. The article proposes a method for finite element analysis of pipe-concrete columns in a physically nonlinear setting by reducing a three-dimensional problem to a twodimensional one based on the hypothesis of plane sections.Method.The equations

Small dilatation pseudo-Anosov mapping classes coming from the simplest hyperbolic braid [PDF]
Algebr. Geom. Topol. 10 (2010) 2041-2060, 2009 In this paper we study the minimum dilatation pseudo-Anosov mapping classes coming from fibrations over the circle of a single 3-manifold, the mapping torus for the "simplest pseudo-Anosov braid". The dilatations that arise include the minimum dilatations for orientable mapping classes for genus g=2,3,4,5,8 as well as Lanneau and Thiffeault's ...

International Journal of Gastrointestinal Intervention, 2020 Plummer–Vinson syndrome is known as the association of dysphagia, upper esophageal web, weight loss, and iron-deficiency anemia. Esophageal dilation therapy is usually necessary to remove webs and to relieve dysphagia in order to encourage oral intake ...

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Studies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of
