Multiwavelength properties of blazars [PDF]
Blazar spectral energy distributions (SEDs) are double peaked and follow a self-similar sequence in luminosity. The so-called "blue" blazars, whose first SED component peaks at X-ray energies, are TeV sources, although with a relatively small fraction of their bolometric luminosities.

The Impact of Plasma Instabilities on the Spectra of TeV Blazars [PDF]
Relativistic jets from blazars are known to be sources of very-high-energy gamma rays (VHEGRs). During their propagation in the intergalactic space, VHEGRs interact with pervasive cosmological photon fields such as the extragalactic background light ...

Abstract Diversity education in the K‐12 years is a contentious issue in the contemporary US context. Given evidence that parental identity influences beliefs about and support for diversity education, we qualitatively explored cisgender‐heterosexual and LGBTQ+ parents’ (N = 609) beliefs about the appropriateness of inclusive educational policies in K ...

Multiwavelength observations of blazars [PDF]
The INTEGRAL mission has played a major role in blazar science, thanks to its sensitive coverage of a spectral region (3-100 keV) that is critical for this type of sources, to its flexibility of scheduling and to the large field of view of its cameras.

Error climate and alienation from teachers: A longitudinal analysis in primary school
Abstract Background Dealing with errors in the classroom is a crucial aspect of instructional quality and has multiple consequences for students' own dealing with errors, their learning and their achievement. The available literature on error climate indicates a paucity of research on the effects of perceived error climate on social aspects such as ...

The VLBA-BU-BLAZAR Multi-Wavelength Monitoring Program
We describe a multiwavelength program of monitoring of a sample of bright γ-ray blazars, which the Boston University (BU) group has being carrying out since June 2007.

Blazar Jets as Possible Sources of Ultra-High Energy Photons: A Short Review
In this paper, I present a qualitative discussion on the prospect of production of ultra-high photons in blazars. The sources are a subclass of active galactic nuclei which host supermassive black holes and fire relativistic jets into the intergalactic ...

BAT AGN Spectroscopic Survey. XVI. General Physical Characteristics of BAT Blazars [PDF]
The recently released 105-month Swift-Burst Alert Telescope (BAT) all-sky hard X-ray survey catalog presents an opportunity to study astrophysical objects detected in the deepest look at the entire hard X-ray (14–195 keV) sky.

Background: The present study analyzes the effects of preoperative serum albumin, hematocrit, and creatinine on postoperative outcomes in patients undergoing carpal tunnel decompression surgery. Methods: The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2011 to 2020.
