Pseudotensors in asymptotically curvilinear coordinates [PDF]
General Relativity and Gravitation, 1987 Die Verff. befassen sich mit geometrischen Größen, die durch Auszeichnung spezieller Koordinatensysteme entstehen, und möchten diese in beliebigen Koordinaten ausdrücken. Was sie dabei erreichen, ist mangels klarer Formulierung ebenso wenig erkennbar wie der Nutzen der Verwendung der veralteten Pseudotensoren.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

The curvature of the conical intersection seam: An approximate second-order analysis [PDF]
, 2004 We present a method for analyzing the curvature (second derivatives) of the conical intersection hyperline at an optimized critical point. Our method uses the projected Hessians of the degenerate states after elimination of the two branching space ...
