Modeling small‐angle scattering data of porous and/or bicontinuous structures in n dimensions

open access: yesJournal of Applied Crystallography, EarlyView.
A small‐angle scattering fitting function is derived for porous materials with arbitrary fractal dimension. It includes a correlation peak and a power law at higher q.Fractal structures are often observed in small‐angle scattering experiments where a simple power law q−α describes the scattering intensity over many orders of magnitude.

Shaped electrodes for adaptive X‐ray optics

open access: yesJournal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Cryo‐EM structure of ALC1 in an open conformation bound to a PARylated nucleosome

open access: yesActa Crystallographica Section D, EarlyView.
Reanalysis of a publicly available cryo‐EM dataset identifies a new conformation of the oncogenic chromatin remodeler ALC1/CHD1L bound to a PARylated nucleosome. This new structure reveals the position of the macro domain in the complex, and may help to understand the large conformational change leading to the activation of ALC1.Nucleosomes are the ...

The Consequences of Soil Organic Carbon for Crop Yield, Farm Productivity and Profit

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Crop choices affect soil organic carbon (SOC) stocks, allowing farmers to manipulate the amount of carbon sequestered in the soil over time. This paper examines the private and public benefits of crop rotations that sequester additional carbon across the province of Saskatchewan, Canada using a novel field‐level dataset from the Saskatchewan ...
