A note on rectifiable curves [PDF]
Edinburgh Mathematical Notes, 1956 Let f be a continuous complex-valued function of a real parameter whose real and imaginary parts are of bounded variation in the range (a, b) of the parameter, so that the range of f is a rectifiable plane curve. The main results connecting the arc-length s with the parametrization are as follows:Theorem 1 (Tonelli).

Topics in differential geometry associated with position vector fields on Euclidean submanifolds
Arab Journal of Mathematical Sciences, 2017 The position vector field is the most elementary and natural geometric object on a Euclidean submanifold. The purpose of this article is to survey six research topics in differential geometry in which the position vector field plays very important roles.

Flow‐Induced Microdomain Alignment During Block Copolymer Graphoepitaxy
Advanced Materials, EarlyView.This study investigates block copolymer flow on topographical templates during solvent vapor annealing and how flow affects the orientation of self‐assembled microdomains. The temporal mapping between flows and microdomain orientation reveals an intriguing dependence of flow‐induced microdomain alignment on film thickness and trench depth, and provides

On pseudo null and null cartan darboux helices in minkowski 3-space
Kuwait Journal of Science, 2016 In this paper, we introduce the notion of pseudo null and null Cartan Darboux helicesin Minkowski 3-space. We characterize the Darboux vectors of the pseudo null andthe null Cartan curves in terms of the Darboux helices and the rectifying curves.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space
Advanced Materials, EarlyView.In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
