We first review on the peculiar characteristics of the bursting and flaring activity of the Soft Gamma-ray Repeaters and Anomalous Xray Pulsars. We then report on the properties of the SGR 1806-20’s Giant Flare occurred on 2004 December 27th, with particular interest on the pre and post flare intensity/hardness correlated variability. We show that these findings are consistent with the picture ...

A test of a new Bayesian approach to solar flare prediction (Wheatland 2004a) is presented. The approach uses the past history of flaring together with phenomenological rules of flare statistics to make a prediction for the probability of occurrence of a large flare within an interval of time, or to refine an initial prediction (which may incorporate other information). The test of the method i...

We present an 89-year-old woman with newly diagnosed atrial flutter associated with a flare of her rheumatoid arthritis (RA). She had a history of diet-controlled type 2 diabetes mellitus, hypertension, and RA and presented with lightheadedness and worsening hand pain. She was found to be in new atrial flutter with rapid ventricular response and to have an active RA flare. In addition to adequa...

In any patient with a first attack of posterior uveitis, it is important to differentiate whether the underlying cause is infective or non-infective in nature. However, when patients with a history of non-infective posterior inflammation present with recurrent symptoms of a flare-up, there is naturally a much lower suspicion of an infective aetiology and immunosuppression is usually commenced f...

In this paper, we measure the rotation of a sunspot in solar active region NOAA 11158 (Solar Target Identifier SOL2011-02-15) that was associated with an M-class flare. The flare occurred when the rotation rate of the sunspot reached its maximum. We further calculate the energy in the corona produced by the sunspot rotation. The energy accumulated in the corona before the flare reached 5.5× 10 ...

The deduction from solar flare X-ray photon spectroscopic data of the energy dependent model-independent spectral index is considered as an inverse problem. Using the well developed regularization approach we analyze the energy dependency of spectral index for a high resolution energy spectrum provided by Ramaty High Energy Solar Spectroscopic Imager (RHESSI). The regularization technique produ...

This paper discusses a general framework called FLARE, that integrates inductive learning using prior knowledge together with reasoning in a non-recursive, propositional setting. FLARE learns incrementally by continually revising its knowledge base in the light of new evidence. Prior knowledge is generally given by a teacher and takes the form of pre-encoded rules. Simple defaults, combined wit...

We investigate the EUV and X-ray flare rate distribution in radiated energy of the late-type active star AD Leo. Occurrence rates of solar flares have previously been found to be distributed in energy according to a power law, dN/dE ∝ E, with a power-law index α in the range 1.5−2.6. If α ≥ 2, then an extrapolation of the flare distribution to low flare energies may be sufficient to heat the co...

In order to study the flare-up of contact allergy, 35 patients with a contact allergy to gold were given an intramuscular injection of 10 mg gold sodium thiomalate, i.e. the anti-rheumatic drug Myocrisin. Clinical reactions comprised an eczematous flare-up of previously positive patch tests to gold and of a previous dermatitis, which occurred in 80% and 26%, respectively; a toxicoderma-like ras...

Swift-detected GRB 080307 showed an unusual smooth rise in its X-ray light curve around 100 s after the burst, at the start of which the emission briefly softened. This ‘hump’ has a longer duration than is normal for a flare at early times and does not demonstrate a typical flare profile. Using a two-component power-law-to-exponential model, the rising emission can be modelled as the onset of t...
