A new type of bake-hardenable high strength hotrolled sheet steel was developed, which shows remarkable increase in tensile strength as well as yield strength after strain age hardening without addition of special elements. The new sheet steel possesses excellent crashworthiness and high fatigue strength, and also shows good formability almost equal to that of conventional high strength sheet s...

∫ F d μt . . . Integral über alle Moduli. ∫ Dγ . . . Integral über alle Eichtransformationen (Diffeomorphismen undWeyl-Transformationen). h[γ] Die durch die Eichtransformation γ aus h erzeugte World-Sheet-Metrik. ĥ(t) Der aus dem durch die Moduli t bestimmten Eichorbit ausgewählte Repräsentant (ebenfalls eine World-Sheet-Metrik). ∏ (α,i)∈f . . . Produkt über eine Anzahl von Koordinaten auf dem ...

We study a two-dimensional superconductor in close proximity to a two-dimensional metallic sheet. The electrons in the superconducting sheet are coupled to those in the metallic sheet by the Coulomb interaction only. We obtain an effective phase-only action for the superconductor by integrating out all the electronic degrees of freedom in the problem. The Coulomb drag of the normal electrons in...

[1] The results of a three-dimensional kinetic simulation of a Harris current sheet are used to show and reproduce the ISEE-1/2, Geotail, and Cluster observations of the magnetotail current sheet structure. Current sheet flapping, current density bifurcation, and reconnection are explained as the results of the evolution of a Harris current sheet, where lower-hybrid drift, kink, and tearing ins...

This brief paper has two purposes. First, we gauge developments in the study of the Antarctic ice sheet over the last seven years by comparing the contents of this issue with the volume produced from an American Geophysical Union meeting, held in September 1998, on the West Antarctic ice sheet. We focus on the uptake of satellite-based observation; ice-ocean interactions; ice streams as foci of...

It is well known that light-sheet illumination can enable optically sectioned wide-field imaging of macroscopic samples. However, the optical sectioning capacity of a light-sheet macroscope is undermined by sample-induced scattering or aberrations that broaden the thickness of the sheet illumination. We present a technique to enhance the optical sectioning capacity of a scanning light-sheet mic...

a procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. the method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. the main advantage of this systematic procedure with respect to other reported procedures is using non-equilibrium s...
