Fine-Grained Monitoring of Gas Flaring in Persian Gulf Countries With Multispectral SDGSAT-1 Nighttime Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Gas flaring is a major source of greenhouse gas and a waste of nonrenewable resources. Remote sensing is suggested to be a capable proxy to provide independent, reliable, and regular observations on global gas flaring.

Multiwavelength polarization observations of the γ-ray bright quasar PKS 0420-014

EPJ Web of Conferences, 2013
We analyze total and polarized intensity images of the quasar PKS 0420-014 obtained monthly with the VLBA at 43 GHz during 2008–2012 along with γ-ray data provided by the Fermi Large Area Telescope and multi-color photometric and polarimetric ...

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Brightest Gamma-Ray-burst Flare Observed in GRB 221009A: Bridging the Last Gap between the Prompt Emission and Flare in Gamma-Ray Bursts

The Astrophysical Journal Letters
Flares are usually observed during the afterglow phases of Gamma-ray bursts (GRBs) in the soft-X-ray, optical, and radio bands—but rarely in the gamma-ray band.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Statistical Study of the Timing of the Appearance of Hα Postflare Loops: Simple Scaling Law Based on Radiative Cooling

The Astrophysical Journal
Recent Sun-as-a-star studies have shown that postflare loops can manifest as a secondary peak in the H α light curve, suggesting that stellar postflare loops are detectable.

Treatment of a Large Cohort of Childhood Chronic Noninfectious Uveitis in a Multicentric Large Study: Adalimumab Versus Methotrexate as First‐Line Therapy

Arthritis &Rheumatology, EarlyView.
Objective Treatment of childhood chronic idiopathic uveitis (cCIU) is predominantly based on studies in juvenile idiopathic arthritis–associated uveitis and expert opinion. Our aim was to report the treatment outcomes of our cohort of cCIU. Methods Retrospective multicenter study involving the rheumatology and ophthalmology units at Florence, Italy ...

A Seven-day Multiwavelength Flare Campaign on AU Mic. III. Quiescent and Flaring Properties of the X-Ray Spectra and Chromospheric Lines

The Astrophysical Journal
We present the X-ray quiescent and flaring properties from a unique, 7 days multiwavelength observing campaign on the M1 flare star AU Mic. Combining the XMM-Newton X-ray spectra with the chromospheric line and broadband near-UV (NUV) and optical ...

ABOUT THE FLASHES’ ACTIVITY OF AO535+26 IN OPTICAL BAND

Odessa Astronomical Publications, 2017
After the great multipulse outburst of Oct. 1995 (JD 2450019) was recorded we followed the optical activity of Be/neutron star binary system A0535+26. The  information on optical flares during 25 years of photoelectric observations was replenished by the
