TL;DR: In this paper, the authors have experimentally and comparatively investigated and compared malignant human cancer cells and tissues before and after irradiating of white and monochromatic synchrotron radiation using Vibrational Circular Dichroism Spectroscopy and video spectroscopy, respectively.
Abstract: In the current study, we have experimentally and comparatively investigated and compared malignant human cancer cells and tissues before and after irradiating of white and monochromatic synchrotron radiation using Vibrational Circular Dichroism Spectroscopy and Video Spectroscopy, respectively. It is clear that malignant human cancer cells and tissues have gradually transformed to benign human cancer cells and tissues under white and monochromatic synchrotron radiation with the passage of time (Figures 1-4) [1-108].

TL;DR: Fluorescence tomography utilizing focussed, tunable, monoenergetic X-rays from synchrotron light sources hold the promise of a non-invasive analytic tool for studying trace elements in specimens, particularly biological, at spatial resolutions of the order of micrometers as mentioned in this paper.
Abstract: Fluorescence tomography utilizing focussed, tunable, monoenergetic X-rays from synchrotron light sources hold the promise of a non-invasive analytic tool for studying trace elements in specimens, particularly biological, at spatial resolutions of the order of micrometers. This note reports an early test at the National Synchrotron Light Source at Brookhaven National Laboratories in which fluorescence tomographic scans were successfully made of trace elements of iron and titanium in NBS standard glass and in a bee.

TL;DR: In this paper, a balance between these two aspects of the same phenomenon is found to determine the degree of beam polarization that can be built up and maintained in a machine. But the balance between the two aspects is not the same as in this paper.

TL;DR: Beniamini et al. as discussed by the authors considered a model for the prompt phase of Gamma-Ray Burst (GRB) emission arising from a magnetized jet undergoing gradual energy dissipation due to magnetic reconnection.
Abstract: We considered a model for the prompt phase of Gamma-Ray Burst (GRB) emission arising from a magnetized jet undergoing gradual energy dissipation due to magnetic reconnection. The dissipated magnetic energy is translated to bulk kinetic energy and to acceleration of particles. The energy in these particles is released via synchrotron radiation as they gyrate around the strong magnetic fields in the jet. At small radii, the optical depth is large, and the radiation is reprocessed through Comptonization into a narrow, strongly peaked, component. At larger distances the optical depth becomes small and radiation escapes the jet with a non-thermal distribution. The obtained spectra typically peak around $\approx 300$keV (as observed) and with spectral indices below and above the peak that are, for a broad range of the model parameters, close to the observed values. The small radius of dissipation causes the emission to become self absorbed at a few keV and can sufficiently suppress the optical and X-ray fluxes within the limits required by observations (Beniamini & Piran 2014).

TL;DR: The small-scale structure of the liquid-vapor interface is investigated using synchrotron x-ray scattering for liquids with different molecular structures and interactions and the large wave-vector increase is attributed to a bending energy for which local and nonlocal contributions are equally important.
Abstract: We have investigated the small-scale structure of the liquid-vapor interface using synchrotron x-ray scattering for liquids with different molecular structures and interactions. The effective momentum-dependent surface energy first decreases from its macroscopic value due to the effect of long-range forces, and then increases with increasing wave vector. The results are analyzed using a recent density functional theory. The large wave-vector increase is attributed to a bending energy for which local and nonlocal contributions are equally important.
