Web3.11). In [6] we have constructed many examples of cylindrical helices and Bertrand curves. Moreover, we have shown that all cylindrical helices and Bertrand curves can be constructed by using the method in [6]. This is one of the papers of the authors joint project entitled “Geometry of ruled surfaces and line congruences”. WebA cylindrical helix is a curve on a generalized cylinder (take any space curve and form a cylinder by taking parallel lines through each point of the space curve) that makes a …

WebApr 12, 2024 · Sequence analysis of the cloned aquaporins indicated that they all contain six α helices (H1-H6), two half helices (HB and HE), and five loops (LE1–LE5). All PIPs contain dual asparagine–proline–alanine (NPA) motifs and an ar/R region with phenylalanine at H2, histidine at H5, threonine, and arginine at LE position (Figure S1 ). WebOct 1, 2024 · One popular approach of generating a helix geometry is to construct a space curve out of plane curves; these are called associated curves. The generic properties of cylindrical helices and Bertrand curves (discovered by Bertrand, 1850) are studied by Izumiya et al. [20] as applications of singularity theory for plane curves and spherical … WebOct 19, 2015 · This setting sets the style in which cartoon helices are rendered.
