Cosmic Crystallography with a Pullback [PDF]
Phys.Lett. A261 (1999) 235-239, 1999 We present a modified version of the cosmic crystallography method, especially useful for testing closed models of negative spatial curvature. The images of clusters of galaxies in simulated catalogs are ``pulled back'' to the fundamental domain before the set of distances is calculated.

, 2003 Crystallography has proven a rich source of ideas over several centuries. Among the many ways of looking at space groups, N. David Mermin has pioneered the Fourier-space approach. Recently, we have supplemented this approach with methods borrowed from algebraic topology. We now show what topology, which studies global properties of manifolds, has to do

Combinatorial problems of (quasi-)crystallography [PDF]
In: Quasicrystals - Structure and Physical Properties, ed. H.-R.
Trebin (Wiley-VCH, Weinheim, 2003), pp. 160-171, 2002 Several combinatorial problems of (quasi-)crystallography are reviewed with special emphasis on a unified approach, valid for both crystals and quasicrystals. In particular, we consider planar sublattices, similarity sublattices, coincidence sublattices, their module counterparts, and central and averaged shelling.

The Evolution of Raw Data Archiving and the Growth of Its Importance in Crystallography [PDF]
arXivThe hardware for data archiving has expanded capacities for digital storage enormously in the past decade or more. This article charts the efforts of IUCr to facilitate discussions and plans relating to raw data archiving and reuse within the various communities of crystallography, diffraction, and scattering.

Abstract OR-2: The Formation of Dps-DNA Complexes under Different Conditions According to Cryo-EM and SAXS [PDF]
International Journal of Biomedicine, 2021 Background: The effect of Dps-DNA co-crystals formation, which occurs in stressed Escherichia coli cells exposed to extreme conditions, is well described in the literature.

Non-Mechanical Multiplexed Beam-Steering Elements Based on Double-Sided Liquid Crystal Metasurfaces
Photonics, 2022 We propose, optimize, fabricate and test beam-steering elements based on double-sided liquid-crystal (LC) metasurfaces allowing for diffractive and spectral multiplexing, and thus covering three different beam deflection directions each.
