Multiple Gamma-Ray Detection Capability of a CeBr3 Detector for Gamma Spectroscopy

open access: yesJournal of Spectroscopy, 2017
The newly developed cerium tribromide (CeBr3) detector has reduced intrinsic gamma-ray activity with gamma energy restricted to 1400–2200 keV energy range.

Induced variability in quantitative characters of groundnut (Arachis hypogaea L.) [PDF]

open access: yesElectronic Journal of Plant Breeding, 2010
Groundnut genotype AK-280 was treated with EMS 40 mM, 60 mM, gamma rays 30 kR, 40 kR, 50 kR and combination treatment of EMS 20mM + gamma rays 20 kR. The observations on various quantitative characters were recorded in M2 generation.

Comparison of radiosensitivity of two rice (Oryza sativa L.) varieties to gamma rays and electron beam in M1 generation

open access: yesElectronic Journal of Plant Breeding, 2017
The present study was carried out to compare effect of gamma rays and electron beam on two rice varieties viz., ADT-37 and ADT(R) 45. Dried seeds of both the varieties were treated with gamma rays and electron beam with different doses viz., 100Gy, 200Gy,

EXTRAGALACTIC GAMMA-RAYS: GAMMA RAY BURSTS AND BLAZARS

open access: yesInternational Journal of Modern Physics A, 2005
The extragalactic gamma-ray sky is dominated by two classes of sources: Gamma-Ray Bursts (GRBs) and radio loud active galactic nuclei whose jets are pointing at us (blazars). We believe that the radiation we receive from them originates from the transformation of bulk relativistic energy into random energy.

Gamma-ray polarimetry [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003
An astrophysics application of a low noise Double-sided Silicon Strip Detector (DSSD) is described. A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gamma-ray universe in the 0.1-20 MeV energy band. Excellent energy resolution and polarization sensitivity are key features of the SMCT.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Supernova Remnants in Gamma Rays

open access: yesUniverse
In the 1960s, the remnants of supernova explosions (SNRs) were indicated as a possible source of galactic cosmic rays through the Diffusive Shock Acceleration (DSA) mechanism.

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.

Generation and measurement of gamma rays with axially symmetric polarization states via Compton scattering

open access: yesPhysical Review Research
Highly polarized gamma rays with linear or circular polarization are essential light sources for nuclear and particle physics experiments, astronomical detector evaluations, and relativistic electron beam diagnostics.
