Direct observation of tRNA-chaperoned folding of a dynamic mRNA ensemble

open access: yesNature Communications, 2023
T-box riboswitches are multi-domain noncoding RNAs that surveil individual amino acid availabilities in most Gram-positive bacteria. T-boxes directly bind specific tRNAs, query their aminoacylation status to detect starvation, and feedback control the ...

Magnetic Small Angle X-Ray Scattering [PDF]

open access: yesLe Journal de Physique IV, 1997
We present first experimental results of the extension of X-ray Magnetic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems.

Serial small- and wide-angle X-ray scattering with laboratory sources

open access: yesIUCrJ, 2022
Recent advances in X-ray instrumentation and sample injection systems have enabled serial crystallography of protein nanocrystals and the rapid structural analysis of dynamic processes. However, this progress has been restricted to large-scale X-ray free-

Energy-sensitive scatter estimation and correction for spectral x-ray imaging with photon-counting detectors [PDF]

open access: yes, 2022
As photon counting detectors are being explored for medical and industrial imaging applications, there is a critical need to understand spectral characteristics of scattered x-ray photons. Scattered radiation is detrimental to x-ray imaging by reducing image quality and quantitative accuracy.
