Form and structure factors with complex scattering vector
Journal of Applied Crystallography, EarlyView.Under grazing incidence, form and structure factors must be evaluated for complex scattering vectors, which can be done by analytic continuation.In condensed‐matter scattering, especially under grazing incidence, complex scattering vectors account for absorption and evanescent waves.

Dynamical refinement against 3D‐ED data in Olex2–AutoChem using the N‐Beam approach
Journal of Applied Crystallography, EarlyView.Dynamical diffraction effects in electron diffraction can now be modelled directly within Olex2–AutoChem using data processed with CrysAlisPro, enabled by a new N‐Beam refinement method based on the Bloch‐wave formalism. This workflow allows dynamical refinement of integrated rotation electron diffraction intensities, improving structural models and ...

Consolidation in times of changes: ISSN from 1989 to 1998
Ciência da Informação, 2015 After the years of creation and implementation of the ISSN system, the network and the International Centre had to face a new stage of development. On a relational level, the sudden death of Mrs Rosenbaum had deeply affected all who had taken part in the

SAS_MoCa: software for small‐angle scattering data analysis of large unilamellar vesicles
Journal of Applied Crystallography, EarlyView.SAS_MoCa is an open‐source Python package for quantitative analysis of small‐angle scattering (SAS) data from large unilamellar vesicles, combining a compositional scattering density profile model of lipid bilayers with a separated form factor description of vesicle size and polydispersity in a Bayesian framework.

Experimental observation of grazing‐incidence X‐ray back‐diffraction with large angular dispersion
Journal of Applied Crystallography, EarlyView.The first experimental observation of grazing‐incidence X‐ray back‐diffraction validates both the dynamical description and a simple geometrical interpretation of its exceptionally large angular dispersion.We report the first experimental observation of grazing‐incidence X‐ray back‐diffraction (GIXBD) exhibiting exceptionally large angular dispersion ...

Using a dumb number to do smart things: learning to dance with ISSN
Ciência da Informação, 2015 This written celebration of 40 years of the ISSN Network is written in two parts. The first takes its starting point in about 1995, about halfway in the life of the ISSN Network, when the Internet was well established and the Web was beginning to have ...

TorchRef: an open‐source PyTorch framework for crystallographic refinement
Journal of Applied Crystallography, EarlyView.TorchRef is an open‐source PyTorch‐based crystallographic refinement framework that exposes all refinable parameters to automatic differentiation, accelerates structure factor evaluation by about two orders of magnitude on a GPU and enables novel workflows such as direct refinement against amplitude differences in time‐resolved crystallography ...
