Denoising framework for X-ray absorption spectroscopy data. [PDF]
J Synchrotron RadiatWe introduce a high‐performance Python‐based XAS denoising package called XASDenoise, which implements our newly developed stationarity warping method and advanced denoising techniques based on Gaussian process regression and a convolutional autoencoder.X‐ray absorption spectroscopy (XAS) is a powerful tool for probing the structural and electronic ...

A high transmission tender X-ray monochromator employing a matched pair of multilayer grating and mirror. [PDF]
J Synchrotron RadiatMonochromators based on multilayer gratings can provide a very high throughput on an extended energy range (1 to 5 keV) in the tender X‐ray domain. A multilayer mirror must be associated with the grating to achieve a fixed exit direction. We show how important an accurate modeling of the reflectivity of these two elements is to achieve both an optimal ...

Post-glitch variability in the anomalous X-ray pulsar 1RXS J170849.0–400910 [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 We report on the first XMM-Newton observation of the Anomalous X-ray Pulsar 1RXS J170849.0-400910. The source was observed in 2003 August and was found at a flux level a factor of about two lower than previous observations. Moreover, a significant spectral evolution appears to be present, the source exhibiting a much softer spectrum than in the past ...

Glitches in Anomalous X‐Ray Pulsars [PDF]
The Astrophysical Journal, 2008 We report on 8.7 and 7.6 yr of Rossi X-Ray Timing Explorer (RXTE) observations of the anomalous X-ray pulsars (AXPs) RXS J170849.0–400910 and 1E 1841–045, respectively. These observations have allowed us to study the long-term timing, pulsed flux, and pulse profile evolution of these objects.

X-ray absorption spectroscopy of lanmodulin-derived peptides bound to rare earth elements. [PDF]
J Synchrotron RadiatThis study uses X‐ray absorption spectroscopy (XAS) to observe the structural and electronic differences of coordination complexes of lanthanides (La, Ce, Pr and Nd) bound by lanmodulin‐derived peptides and other organic chelators in aqueous solution. The reported sensitivity of XAS for subtle changes in lanthanide coordination environment supports its

Thermal X-Ray Pulses Resulting From Pulsar Glitches [PDF]
International Astronomical Union Colloquium, 2000 Abstract The non-spherical symmetric and exact thermal evolution model is used to calculate the transient thermal response to pulsar glitches. The three ways of energy release originated from glitches, namely the ‘shell’, ‘ring’ and ‘spot’ cases are compared.

Best Practice: CT-guided Adaptive Radiotherapy Reference Planning on the Ethos Platform. [PDF]
J Appl Clin Med PhysAbstract Online adaptive radiotherapy (ART) enables treatment plan modifications based on the patient's anatomy at each fraction, addressing limitations of conventional radiotherapy that relies on a static pre‐treatment plan. CT‐guided ART (CTgART), as implemented on the Varian Ethos platform, has gained increased clinical adoption over the past ...

A Glitch in an Anomalous X-Ray Pulsar [PDF]
The Astrophysical Journal, 2000 We report the detection of a sudden spin-up of the 11 s anomalous X-ray pulsar 1RXS J170849.0-4000910 in regular timing observations made with the Rossi X-ray Timing Explorer. The event, which occurred between MJD 51446 (1999 September 25) and 51472 (1999 October 21), is well characterized by an increase in the rotational frequency of magnitude (Delta ...
