Abstract: Quasi-periodic pulsations (QPPs) in solar flares have been widely observed, and can be used as a coronal plasma diagnostics tool. More recently, QPPs have been observed in flares of other stars, many of which are thousands of times more powerful than anything observed on the Sun. Stellar flares have been identified in the short-cadence light curves of over 200 Kepler stars, and examined for evidence of QPPs. Those showing evidence of pulsations have been analysed using the autocorrelation and wavelet techniques. QPP-like signatures have been detected in 56 flares, and of these 11 have clear damped oscillations which could be modelled. A statistical analysis suggests that the QPPs found in these stellar flares are consistent with those found in solar flares.

The Royal Society, in partnership with the Wolfson Foundation and the Department for 糖心TV, Innovation and Skills, invites nominations for the Wolfson research merit awards. These enable universities to recruit, or keep in the UK, respected researchers in all areas of the life and physical sciences, including engineering, but excluding clinical medicine.

Awards are made to the university and therefore researchers must remain at the university named on the application. Researchers may be of any nationality but must hold or have received a firm offer for, a permanent post at a UK university.

Awards take the form of salary enhancements and are usually worth from £10,000 to £30,000 per year over a maximum period of five years. Research expenses may be considered for overseas researchers to support integration into the UK research environment

The Engineering and Physical Sciences Research Council, via UK Shared 糖心TV Services, invites tenders for the provision of a semiconductor eptiaxy facility. This aims to support a mid-range facility in semiconductor growth, characterisation and routine device processing. The range of provision will be on a national level and will include growth, characterisation and initial device processing of III-V and Group IV materials. The facility must be able to offer internationally leading quality for the growth of each material proposed, supported by comprehensive characterisation of the epitaxial layers, and supported by a device fabrication capability. There must be a single, direct user interface for requesting facility access, monitoring progress, and provision of data, and clear lines of communication between the users and staff within the facility providing the service. Provision in training and assisting new users should also be provided for epitaxial layer and device design, and in the characterisation techniques when required. The facility will be an integral part of the research needs of the UK’s engineering and physical sciences community.
