Article describes the results of friction stir welding of aluminum and steel, in which heat input and high strain rate deformation during resulted in the diffusion-based formation of a FexAly intermetallic compound (IMC) layer.

The article describes cosmic expansion as correlated with the standpoints of local observers’ co-moving horizons. In keeping with relational quantum mechanics, which claims that quantum systems are only meaningful in the context of measurements, the authors suggest that information gets ergodically “diluted” in our isotropic and homogeneous expanding Universe, so that an observer detects just a limited amount of the total cosmic bits.

Paper examines the impacts of variations in the mean annual lake bottom temperature (MALBT) on talik development and permafrost degradation beneath expanding thermokarst lakes in the Beiluhe Basin on the Qinghai–Tibetan Plateau.
