Until recently, X-ray flares during the afterglow of gamma-ray bursts (GRBs) were a rarely detected phenomenon; thus, their nature is unclear. During the afterglow of GRB 050502B, the largest X-ray flare ever recorded rose rapidly above the afterglow light curve detected by the SwiftX-Ray Telescope. The peak flux of the flare was >500 times that of the underlying afterglow, and it occurred >12 ...
We present a case study of solar flare forecasting by means metadata feature time series, treating it as prominent class-imbalance and temporally coherent problem. Taking full advantage pre-flare series in active regions is made possible via the Space Weather Analytics for Solar Flares (SWAN-SF) benchmark dataset; partitioned collection multivariate region properties comprising 4075 spanning ov...
PURPOSE To evaluate the possible inhibitory effects of hot water extract of Scutellariae radix and its major components (baicalein, baicalin, and wogonin) on experimental elevation of aqueous flare in pigmented rabbits. METHODS To produce aqueous flare elevation in rabbits, prostaglandin E(2) (PGE(2)), 25 microg/mL, was applied to the cornea with the use of a glass cylinder, or lipopolysaccha...
OBJECTIVES Despite advances in systemic lupus erythematosus (SLE) treatment, many patients suffer from the disease and side effects. Atacicept is a fusion protein that blocks B-lymphocyte stimulator and a proliferation-inducing ligand, which are increased in patients with SLE. METHODS In this double-blind, placebo-controlled study, patients with moderate-to-severe SLE were randomised to ataci...
BACKGROUND To evaluate the incidence of flare-ups and identify the risk factors including age, gender, tooth type, number of root canals, initial diagnosis, the type of irrigation regimen, treatment modality and the number of visits, in patients who received root canal treatment from January 2002 to January 2008. METHODS Records of 1819 teeth belonging to 1410 patients treated by 1 endodontic...
We derive the minimum observing time scales to detect a blazar at a given flux level with the LAT on GLAST in the scanning and pointing modes. Based upon Phase 1 observations with EGRET, we predict the GLAST detection rate of blazar flares at different flux levels. With some uncertainty given the poor statistics of bright blazars, we predict that a blazar flare with integral flux > ∼ 200 × 10−8...
A new method for automated coronal loop tracking, in both spatial and temporal domains, is presented. The reliability of this technique was tested with TRACE 171Å observations. The application of this technique to a flare-induced kink-mode oscillation, revealed a 3500 km spatial periodicity which occur along the loop edge. We establish a reduction in oscillatory power, for these spatial periodi...
Context. Coordinated observations of a GOES B4.8 microflare with SDO’s Atmospheric Imaging Assembly (AIA) and the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) on 2010 July 31 show that emission in all seven of AIA’s EUV channels brightened simultaneously nearly 6 min before RHESSI or GOES detected emission from plasma at temperatures around 10 MK. Aims. To help interpret these and AIA...
OBJECTIVE To present a rare case of breast cancer associated with both inflammatory muscle disease and liver disease as a paraneoplastic syndrome. CLINICAL PRESENTATION AND INTERVENTION A woman with breast cancer presented with elevated liver enzymes and progressive proximal muscle weakness. Liver biopsy was consistent with hepatitis and muscle biopsy revealed myositis. The start of corticost...
Magnetic activity phenomena are characteristic for T-Tauri stars as well as protostellar class I objects. A model for the flare-like emissivity based on a macroscopic plasma instability, the resistive tearing mode, is proposed. The dispersion relation for the unstable modes for the appropriate partially ionized dusty plasma regime is presented and solved numerically. The results indicate that t...
