Chasing the Neutrino Blazar Candidates
In our study of the correlations between IceCube-detected neutrino events and γ -ray properties of blazars, we recognize the inherent challenges posed by the limited detection of neutrinos.

Radiation processes in blazars [PDF]
We present an overview of the current theoretical models attempting to describe the structure and radiative processes operating in blazars and discuss the observational constraints that these models must confront.

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 ...

Association of the IceCube neutrinos with CAZ blazar light curves
The IceCube Neutrino Observatory has detected several hundred high-energy neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not known which sources emit them.

The results of both BVRI CCD photometric monitoring and fast photometry for 8 blazars and variable quasars are presented. There is intraday variability for 6 blazars and very short timescales (minutes to two hours) variability for 5 objects. Implications for relativistic beaming are briefly discussed.

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.

Recognizing Blazars Using Radio Morphology from the VLA Sky Survey
Blazars are radio-loud active galactic nuclei whose jets have a very small angle to our line of sight. Observationally, the radio emissions are mostly compact or compact-core with a one-sided jet.

Long-Term Optical Monitoring of Blazars
Systematic monitoring of specific targets in the optical regime was historically applied on a very narrow sample of known variable stars. The discovery of blazars in the 20th century brought to the foreground the need for new global sky surveys, covering

Can teaching be taught? Improving teachers' pedagogical skills at scale in rural Peru
We evaluate the impact of a large‐scale teacher coaching program in Peru, a context with high teacher turnover, on teachers' pedagogical skills and student learning. Previous studies find that small‐scale coaching programs can improve teaching of reading and science in developing countries.
