On the Spectrum and Polarization of Magnetar Flare Emission
Galaxies, 2018 Bursts and flares are among the distinctive observational manifestations of magnetars, isolated neutron stars endowed with an ultra-strong magnetic field ( B ≈ 10 14 – 10 15 G).

Observation of metre-scale impactors by the Desert Fireball Network [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Earth is impacted by 35-40 metre-scale objects every year. These meteoroids are the low mass end of impactors that can do damage on the ground. Despite this they are very poorly surveyed and characterised, too infrequent for ground based fireball ...

Advanced Science, EarlyView.Chronic microinflammation in high myopia suppresses MANF in lens epithelial cells. MANF normally resides within MAMs and promotes ubiquitin‐mediated degradation of the ER Ca2+ pump SERCA2. MANF loss causes pathological SERCA2 accumulation, MAM hyperassembly, and disrupted ER‐to‐mitochondria Ca2+ transfer, leading to mitochondrial failure, oxidative ...

Multipulse Fermi Gamma-Ray Bursts. I. Evidence of the Transition from Fireball to Poynting-flux-dominated Outflow [PDF]
Astrophysical Journal Supplement Series, 2018 The composition of a jet is still an unsolved problem in gamma-ray bursts (GRBs). Several previous studies have suggested that the prompt emission spectrum of GRBs is likely to consist of a few components that may arise from different jet compositions ...

Advanced Science, EarlyView.ABSTRACT Osteoarthritis (OA) is a progressive and disabling joint disease driven by oxidative stress, chondrocyte senescence and extracellular matrix (ECM) degradation, yet lacks effective disease‐modifying treatments. In this study, we identified miR‐197‐3p as a previously unrecognized, cartilage‐protective miRNA significantly downregulated in both ...
