Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

Acta Crystallographica Section D, Volume 82, Issue 5, Page 471-483, May 2026.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...

Narrowing the “Digital Divide”: The Role of Fixed and Mobile Infrastructure

Journal of Economics &Management Strategy, Volume 34, Issue 4, Page 799-829, Winter 2025.
ABSTRACT We study the substitution between fixed and mobile broadband services in South Africa using survey data on 134,000 individuals collected between 2009 and 2014. In our discrete‐choice model, individuals choose fixed or mobile voice and data services in a framework that allows these services to be considered substitutes or complements.

Oblique diffraction geometry for the observation of several non‐coplanar Bragg reflections under identical illumination

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1439-1446, August 2025.
We derive a closed analytical expression that allows determination of the strain and lattice rotation from the deviation of experimental observables (e.g. goniometer angles) from their nominal position for an unstrained lattice. We also propose an experimental geometry wherein such measurements can be carried out while keeping the illuminated sample ...
