A method based on the curvelet transform is introduced to estimate the orientation distribution from
two-dimensional images of small anisotropic particles. Orientation of fibers in paper is considered as a particular
application of the method. Theoretical aspects of the suitability of this method are discussed and its efficiency is
demonstrated with simulated and real images of fibrous systems. Comparison is made with two traditionally used
methods of orientation analysis, and the new curvelet-based method is shown to perform better than these tradi-
tional methods.

Pseudorapidity dependence of the anisotropic flow of charged particles in Pb–Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Elsevier B.V., 2016)We present measurements of the elliptic (v2), triangular (v3) and quadrangular (v4) anisotropic azimuthal flow over a wide range of pseudorapidities (−3.5 <η<5). The measurements are performed with Pb–Pb collisions at ... -

The Calderón problem in transversally anisotropic geometries
Ferreira, David Dos Santos; Kurylev, Yaroslav; Lassas, Matti; Salo, Mikko (European Mathematical Society Publishing House; European Mathematical Society, 2016)We consider the anisotropic Calder´on problem of recovering a conductivity matrix or a Riemannian metric from electrical boundary measurements in three and higher dimensions. In the earlier work [13], it was shown that ...
