Searches for IceCube neutrinos from blazar flares using correlations with gamma-ray lightcurves [PDF]
EPJ Web of Conferences, 2019 Blazars have long been considered as accelerator candidates for cosmic rays. In such a scenario, hadronic interactions in the jet would produce neutrinos and gamma rays.

Blazars at Very High Energies: Emission Modelling
Galaxies, 2022 Blazars are very broadband cosmic sources with spectra spanning over twenty orders of magnitude in frequency, down to the 100 MHz regime in the radio range, up to VHE at several tens of TeV.

Immunohistopathology of oral mucosal chronic graft‐versus‐host disease severity and duration
Oral Diseases, Volume 29, Issue 8, Page 3346-3359, November 2023., 2023 Abstract Objective Chronic graft‐versus‐host disease (cGVHD) is the main cause of late non‐relapse mortality following hematopoietic cell transplantation. Oral mucosal (om‐) cGVHD is common, but diagnosis and assessment rely on clinical interpretation and patient‐reported symptoms.

X-ray Spectral Evolution of High Energy Peaked Blazars
Galaxies, 2020 The synchrotron hump of the high energy peaked blazars generally lies in the 0.1–10 keV range and such sources show extreme flux and spectral variability in X-ray bands. Various spectral studies showed that the X-ray spectra of high energy peaked blazars

Swift detection of all previously undetected blazars in a micro-wave flux-limited sample of WMAP foreground sources [PDF]
, 2007 Almost the totality of the bright foreground sources in the WMAP CMB maps are blazars, a class of sources that show usually also X-ray emission. However, 23 objects in a flux-limited sample of 140 blazars of the WMAP catalog (first year) were never ...

Radio core-dominance of Fermi-blazars: implication for blazar unification [PDF]
Astrophysics and Space Science, 2021 ...The distribution of radio core-dominance is consistent with average projection angles of 13.5, 14.8, 16.8, 20.4, and 28.2 for ISPs, LSPs, FSRQs, HSPs, and radio galaxies, respectively. Linear regression analyses of our data yield significant anti-correlation r greater than 0.60 between core-dominance parameter and extended luminosity in each ...

A tool to understand emission mechanisms of blazars through their high‐energy gamma‐ray emission
Astronomische Nachrichten, Volume 344, Issue 6, August 2023., 2023 The blazar SED is characterized by two energy components. Evidence suggests that the low‐energy component is generated by the synchrotron mechanism, but for the high‐energy component, the mechanism is still uncertain. Two main models have been proposed to explain this emission. According to the leptonic model, a correlation between the emission of both

The impact of guardian's usage of the Internet on children's cognitive skills
International Studies of Economics, Volume 18, Issue 2, Page 193-210, June 2023., 2023 Abstract In the digital age, the internet has become an essential source of information gathering and maintains a network of social contact. In this paper, we use microdata from the China Family Panel Studies to examine the effects of guardian's internet use on teenager's cognitive skills.

Multi-Wavelength Intra-Day Variability and Quasi-Periodic Oscillation in Blazars
Galaxies, 2017 We reviewed multi-wavelength blazars variability and detection of quasi-periodic oscillations on intra-day timescales. The variability timescale from a few minutes to up to less than a days is commonly known as intra-day variability.
