GNSS Total Electron Content Data (60 s) at Ny-Ålesund in 2016

open access: yes, 2020
This data set contains Total Electron Content data at 60 seconds time resolution at Ny-Ålesund, Svalbard. The measurements were collected by the University of Bergen using a NovAtel GPStation-6 global navigation satellite system receiver.

Total electron content variations in the ionosphere before the Colima, Mexico, earthquake of 21 January 2003 [PDF]

open access: yesGeofísica Internacional, 2005
Anomalous ionospheric variations associated with the process of strong earthquake (M>5) preparation has been fairly well established. To check possible ionospheric variations connected with the recent Colima earthquake, M=7.8, of 21 January 2003, the ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

GPS Total Electron Content measurements at low latitudes in Brazil for low solar activity [PDF]

open access: yesGeofísica Internacional, 2004
Variations of ionospheric Total Electron Content (TEC) have been calculated using GPS data at station Presidente Prudente, Brazil (22.1° S; 51.4° W) in 1997, a period of low solar activity. Two hourly TEC averages are presented for the period.

Detection of ionospheric signatures from GPS-derived total electron content maps

open access: yesJournal of Geodetic Science, 2014
The processing of measurement data from satelliteconstellations such as Global Navigation Satellite Systems(GNSS), including the well-known Global PositioningSystem (GPS), have been successfully applied to virtuallyall areas of geophysical sciences.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
