Journal ArticleDOI
Baroclinic Instability and Loss of Balance
TL;DR: In this article, the authors analyzed the particular example of an unbalanced instability of a balanced, horizontally uniform, vertically sheared current, as it occurs within the Boussinesq equations.
Journal ArticleDOI
Sparsity-based single-shot subwavelength coherent diffractive imaging
Alexander Szameit,Yoav Shechtman,Eliyahu Osherovich,Elad Bullkich,Pavel Sidorenko,Hod Dana,Stefan Steiner,Ernst-Bernhard Kley,Snir Gazit,T. Cohen-Hyams,Shy Shoham,Michael Zibulevsky,Irad Yavneh,Yonina C. Eldar,Oren Cohen,M. Segev +15 more
TL;DR: In this paper, a sparsity-based single-shot subwavelength resolution coherent diffractive imaging (CDI) method was proposed to reconstruct sub-wavelength features from far-field intensity patterns at a resolution several times better than the diffraction limit.
Journal ArticleDOI
A Plurality of Sparse Representations Is Better Than the Sparsest One Alone
Michael Elad,Irad Yavneh +1 more
TL;DR: It is shown that while the maximum a posteriori probability (MAP) estimator aims to find and use the sparsest representation, the minimum mean- squared-error (MMSE) estimators leads to a fusion of representations to form its result, which is a far more accurate estimation in terms of the expected lscr2 -norm error.

Sparsity-based single-shot sub-wavelength coherent diffractive imaging
Alexander Szameit,Yoav Shechtman,Eliyahu Osherovich,Elad Bullkich,Pavel Sidorenko,Hod Dana,Stefan Steiner,E.-B. Kley,Snir Gazit,T. Cohen-Hyams,Shy Shoham,Michael Zibulevsky,Irad Yavneh,Yonina C. Eldar,Oren Cohen,Mordechai Segev +15 more
TL;DR: A method of performing single-shot sub-wavelength resolution Coherent Diffractive Imaging (CDI), i.e. algorithmic object reconstruction from far-field intensity measurements, applicable to objects that are sparse in a known basis.
Journal ArticleDOI
Anisotropy and coherent vortex structures in planetary turbulence.
TL;DR: High-resolution numerical simulations were made of unforced, planetary-scale fluid dynamics based on the quasi-geostrophic equations for a Boussinesq fluid in a uniformly rotating and stably stratified environment, which is an idealization for large regions of either the atmosphere or ocean.
