Polarization and Spectral Energy Distribution in OJ 287 during the 2016/17 Outbursts

open access: yesGalaxies, 2017
We report optical photometric and polarimetric observations of the blazar OJ 287 gathered during 2016/17. The high level of activity, noticed after the General Relativity Centenary flare, is argued to be part of the follow-up flares that exhibited high ...

GRB Fireball Physics: Prompt and Early Emission

open access: yes, 2006
We review the fireball shock model of gamma-ray burst prompt and early afterglow emission in light of rapid follow-up measurements made and enabled by the multi-wavelength Swift satellite.

Efficacy and Safety of Subcutaneous Anifrolumab in Systemic Lupus Erythematosus: the Randomized, Phase 3, TULIP‐SC Study

open access: yesArthritis &Rheumatology, Accepted Article.
Objective The multinational, phase 3, double‐blind, placebo‐controlled TULIP‐SC trial evaluated the efficacy and safety of subcutaneous anifrolumab in adults who have moderate‐to‐severe SLE activity, despite receiving standard therapy. Methods Adults with SLE received subcutaneous anifrolumab 120 mg or placebo once weekly for 52 weeks (1:1 ...

FUMES. IV. Optical and Far-ultraviolet Spectra of a Flare on the M Dwarf GJ 4334

open access: yesThe Astronomical Journal
On 2017 September 20, we observed GJ 4334, an M5V dwarf rotating with a period of 23.5 days, simultaneously with both the Space Telescope Imaging Spectrograph aboard Hubble (1160–1710 Å) and the Dual Imaging Spectrograph mounted on the 3.5 m telescope at

Exploring the blazar zone in High Energy flares of FSRQs

open access: yes, 2014
The gamma-ray emission offers a powerful diagnostic tool to probe jets and their surroundings in flat spectrum radio quasars (FSRQ). In particular, sources emitting at high energies (>10 GeV) give us the strongest constraints.

‘Where are the adults?’: Troubling child‐activism and children's political participation

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Hemolysis Detected Following the Preparation and Collection of Blood in a Porcine Model Using a Syringe‐Based Aspiration Thrombectomy System for Autotransfusion

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Autologous transfusion of filtered, unwashed blood is a technique to mitigate the effects of blood loss during mechanical thrombectomy, but the degree of hemolysis resulting from this approach and guidance for blood return in this setting is not well understood.

S5 1803+78 Revisited

open access: yesActa Polytechnica, 2012
We report on our optical monitoring of the BL Lac object S5 1803+78 from 1996 to 2011. The source showed no clear periodicity, but a time scale of about 1 300 days between major flares is possibly present. No systematic trend of the color index with flux

Optical and Gamma-Ray Variability Behaviors of 3C 454.3 from 2006 to 2011

open access: yes, 2018
We present our photometric monitoring of a flat spectrum radio quasar (FSRQ) 3C 454.3 at Yunnan observatories from 2006 to 2011. We find that the optical color of 3C 454.3 shows obvious redder-when-brighter trend, which reaches a saturation stage when ...
