Single‐exposure X‐ray phase imaging microscopy with a grating interferometer

Journal of Synchrotron Radiation, Volume 29, Issue 3, Page 794-806, May 2022., 2022
This work presents and extends the single‐exposure phase imaging capabilities of X‐ray grating interferometry as demonstrated by an implementation at beamline I13‐1 of the Diamond Light Source. The results are especially relevant for future single‐pulse imaging experiments at X‐ray free‐electron lasers.The advent of hard X‐ray free‐electron lasers ...

Modeling‐Assisted Design of Thermostable Benzaldehyde Lyases from Rhodococcus erythropolis for Continuous Production of α‐Hydroxy Ketones

ChemBioChem, Volume 23, Issue 7, April 5, 2022., 2022
A novel benzaldehyde lyase for the production of chiral α‐hydroxy ketones was identified by a machine learning model and two variants with altered substrate scopes were created by rational design. All three variants exhibit significantly higher thermostability compared to the only previously described benzaldehyde lyase.

The Relationship of Lightning Radio Pulse Amplitudes and Source Altitudes as Observed by LOFAR

Earth and Space Science, Volume 9, Issue 4, April 2022., 2022
Abstract When a lightning flash is propagating in the atmosphere it is known that especially the negative leaders emit a large number of very high frequency (VHF) radio pulses. It is thought that this is due to streamer activity at the tip of the growing negative leader.

Association of circulating PLA2G7 levels with cancer cachexia and assessment of darapladib as a therapy

Journal of Cachexia, Sarcopenia and Muscle, Volume 12, Issue 5, Page 1333-1351, October 2021., 2021
Abstract Background Cancer cachexia (CCx) is a multifactorial wasting disorder characterized by involuntary loss of body weight that affects many cancer patients and implies a poor prognosis, reducing both tolerance to and efficiency of anticancer therapies.

Timing Calibration and Windowing Technique Comparison for Lightning Mapping Arrays

Earth and Space Science, Volume 8, Issue 7, July 2021., 2021
Abstract Since their introduction 22 years ago, lightning mapping arrays (LMA) have played a central role in the investigation of lightning physics. Even in recent years with the proliferation of digital interferometers and the introduction of the LOw Frequency ARray (LOFAR) radio telescope, LMAs still play an important role in lightning science.

Needle Propagation and Twinkling Characteristics

Journal of Geophysical Research: Atmospheres, Volume 126, Issue 6, 27 March 2021., 2021
Abstract Recently, a new lightning phenomena, termed needles, has been observed in both VHF and in optical along positive lightning leaders. They appear as small (<100 m) leader branches that undergo dielectric breakdown at regular intervals (called twinkles).
