  • Island shapes show differing self-affine scaling

    What the study found Earth's islands show different self-affine scaling behavior depending on the geometric feature measured. The authors report four Hurst exponent estimates, which are roughness measures for self-affine surfaces, and these estimates are sorted by increasing expected influence of coastal processes. Why the authors say this matters The study suggests that these patterns…

  • Hausdorff dimension computed for shrinking targets in affine systems

    What the study found The authors compute the Hausdorff dimension of a set of points that recur infinitely often to a shrinking target of geometric balls in certain affine iterated function systems. Their results apply to a representative class of affine systems made of a pair of diagonal affine maps. Why the authors say this…
