On the curvatures of the ruled surfaces of b-lift curves
Cumhuriyet Science Journal, 2021 In this study, we defined a new curve which is called the B-Lift curve, also obtained the Frenet vectors of the B-Lift curve. The ruled surfaces have been produced by taking base curves B-Lift curves.

Osculating Type Ruled Surfaces with Type-2 Bishop Frame in E3
SymmetryThe aim of this work is to investigate osculating type ruled surfaces with a type 2-Bishop frame in E3. We accomplish this by employing the symmetry of osculating curves.

Ruled Surfaces and Tangent Bundle of Unit 2-Sphere of Natural Lift Curves
GAZI UNIVERSITY JOURNAL OF SCIENCE, 2020 This article deals with the isomorphism between unit dual sphere, DS^2, and the subset of the tangent bundle of unit 2-sphere, TM . According to E. Study mapping, a ruled surface in〖 R〗^3corresponds to each curve on DS^2.

Ruled surfaces of finite type [PDF]
Bulletin of the Australian Mathematical Society, 1990 We show that a ruled surface of finite type in a Euclidean space is a cylinder on a curve of finite type or a helicoid in Euclidean 3-space.

Jordan groups and elliptic ruled surfaces
, 2014 We prove that an analogue of Jordan's theorem on finite subgroups of general linear groups holds for the groups of biregular automorphisms of elliptic ruled surfaces. This gives a positive answer to a question of Vladimir L.

Theta divisors and Ulrich bundles on geometrically ruled surfaces [PDF]
Annali di Matematica Pura ed Applicata, 2019 We consider the following question: For which invariants g and e is there a geometrically ruled surface $$S \rightarrow C$$ S → C over a curve C of genus g with invariant e such that S is the support of an Ulrich line bundle with respect to a very ample ...

𝔸1–connected components of ruled surfaces [PDF]
Geometry & Topology, 2019 A conjecture of Morel asserts that the sheaf of $\mathbb A^1$-connected components of a space is $\mathbb A^1$-invariant. Using purely algebro-geometric methods, we determine the sheaf of $\mathbb A^1$-connected components of a smooth projective surface,

PSEUDO-MINIMALITY AND RULED SURFACES [PDF]
Vestnik Tomskogo gosudarstvennogo universiteta. Matematika i mekhanika, 2020 This paper is a follow-up to the author's series of works about shape modeling for an orthotropic elastic material that takes an equilibrium form inside the area with the specified boundaries. V.M. Gryanik and V.I. Loman, based on thin shell equilibrium equations, solved about 30 years ago a similar problem for an isotropic mesh attached to rigid ...

Cyclic and ruled Lagrangian surfaces in complex Euclidean space
, 2007 We study those Lagrangian surfaces in complex Euclidean space which are foliated by circles or by straight lines. The former, which we call cyclic, come in three types, each one being described by means of, respectively, a planar curve, a Legendrian ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
