Full-wave simulations are used to obtain and verify the existence of the SIP in the three-way coupled waveguide and fine-tune the geometry such that a beam would be in synchronism at or near the SIP.  ...  The three-way waveguide SWS exhibits a moderately high Pierce impedance in the vicinity of a nearly-stationary inflection point, making the SWS geometry potentially useful for improving the power gain  ...  We thank Dassault Systèmes for providing CST Studio Suite, which has been instrumental in this work.  ...

In dimensions 3 and 4 the SICs are understandable in terms of elliptic curves, but a general statement escapes us. The geometry of the SICs in 3 and 4 dimensions is discussed in some detail.  ...  In prime dimensions the former are closely tied to an elliptic normal curve symmetric under the Heisenberg group, while the latter are believed to be orbits under the Heisenberg group in all dimensions  ...  Acknowledgments I thank Subhash Chaturvedi for telling me about the Segre configuration, at a point in time when neither of us knew about Segre. Both of us give our best wishes to Tony!  ...

We establish restrictions on the number of real nodes of such curves and construct curves realizing the extreme numbers of real nodes.  ...  We introduce and begin the topological study of real rational plane curves, all of whose inflection points are real.  ...  Of these five, two have three solitary points and no real nodes, while three have two solitary points and one real node.  ...

Two pseudo-metrics on C are introduced, the Klein-Hilbert distance d and the Harnack distance dy, which are characterized in various ways.  ...  Summary: “The problem of drawing the oblique frontal projection (dimetrical oblique axonometry with axes x and z at right angle) is resolved in this paper on the basis of two non-juxtapositioned orthogonal  ...
