Inhomogeneous M-theory cosmologies [PDF]
Journal of Mathematical Physics, 2002 We study a class of inhomogeneous and anisotropic G2 string cosmological models. In the case of separable G2 models we show that the governing equations reduce to a system of ordinary differential equations. We focus on a class of separable G2 M-theory cosmological models, and study their qualitative behavior (a class of models with time-reversed ...

Advanced Engineering Materials, EarlyView.Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.

Die Behandlung des systematischen Fehlers bei Niederschlagsmessungen
Meteorologische Zeitschrift, 1992 Bei allen Arten von Niederschlagsmessungen mit konventionellen Meßgeräten treten geräteabhängig systematische Meßfehler auf, wobei im allgemeinen der aktuell gefallene Niederschlag unterschätzt wird.

Supersymmetric inhomogeneous field theories in 1+1 dimensions
Journal of High Energy Physics, 2022 We study supersymmetric inhomogeneous field theories in 1+1 dimensions which have explicit coordinate dependence. Although translation symmetry is broken, part of supersymmetries can be maintained.

Inhomogeneity effects in Cosmology
, 2011 This article looks at how inhomogeneous spacetime models may be significant for cosmology. First it looks at how the averaging process may affect large scale dynamics, with backreaction effects leading to effective contributions to the averaged energy ...

A note on generalized hydrodynamics: inhomogeneous fields and other concepts [PDF]
, 2016 Generalized hydrodynamics (GHD) was proposed recently as a formulation of hydrodynamics for integrable systems, taking into account infinitely-many conservation laws. In this note we further develop the theory in various directions.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study
Advanced Engineering Materials, EarlyView.This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

The Hyades open cluster is chemically inhomogeneous [PDF]
, 2016 We present a high-precision differential abundance analysis of 16 solar-type stars in the Hyades open cluster based on high resolution, high signal-to-noise ratio (S/N ~ 350 - 400) spectra obtained from the McDonald 2.7m telescope.

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
