Superconducting undulator activities at the European X-ray Free-Electron Laser Facility

open access: yesFrontiers in Physics, 2023
For more than 5 years, superconducting undulators (SCUs) have been successfully delivering X-rays in storage rings. The European X-Ray Free-Electron Laser Facility (XFEL) plans to demonstrate the operation of SCUs in X-ray free-electron lasers (FELs ...

Vimentin intermediate filaments stabilize dynamic microtubules by direct interactions

open access: yesNature Communications, 2021
The tasks of the cytoskeleton depend on the fine-tuned interplay between the three filamentous components: actin filaments, microtubules, and intermediate filaments.

Metal Halide Perovskites for X-ray Imaging Scintillators and Detectors

open access: yes, 2021
Radiation detection, using materials to convert high-energy photons to low-energy photons (X-ray imaging) or electrical charges (X-ray detector), has become essential for a wide range of applicatio...

An X-ray polarimeter for hard X-ray optics [PDF]

open access: yes, 2006
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

Radionuclide diagnosis of ureteric function in patients with stages I-IV cancer of the cervix uteri

open access: yesОпухоли женской репродуктивной системы, 2014
The experience with serial renal scintigraphy demonstrated its high informative value and safety in evaluating the severity of intrarenal urine outflow disorders; however, failure to make an objective assessment of ureteral patency considerably limits ...

In situ X-ray area detector flat-field correction at an operating photon energy without flat illumination

open access: yesJournal of Synchrotron Radiation, 2023
Flat-field calibration of X-ray area detectors is a challenge due to the inability to generate an X-ray flat-field at the selected photon energy the beamline operates at, which has a strong influence on the measurement behavior of the detector.

Clocking Femtosecond X Rays [PDF]

open access: yesPhysical Review Letters, 2005
Linear-accelerator-based sources will revolutionize ultrafast x-ray science due to their unprecedented brightness and short pulse duration. However, time-resolved studies at the resolution of the x-ray pulse duration are hampered by the inability to precisely synchronize an external laser to the accelerator.

Intra-nosological diagnosis of endometrial cancer

open access: yesОпухоли женской репродуктивной системы, 2014
The study is based on the analysis of comprehensive ultrasound examinations of 158 patients with a verified diagnosis of endometrial cancer (EC). It was conducted, by taking into account the concept of 3 types of microinvasive EC growth. Echosemiotics in
