A simple method for estimating the major nuclide fractional fission rates within light water and advanced gas cooled reactors
The standard method for calculating anti-neutrino emissions from a reactor involves knowing the fractional fission rates for the most important fissioning nuclides in the reactor. To calculate these rates requires detailed reactor physics calculations based upon the reactor design, fuel design, burnup dependent fuel composition, location of specific fuel assemblies in the core and detailed operational data from the reactor. This has only been published for a few reactors during specific time periods, whereas to be of practical use for anti-neutrino reactor monitoring it is necessary to be able to predict these on the publicly available information from any reactor, especially if using these data to subtract the anti-neutrino signal from other reactors to identify an undeclared reactor and monitor its operation. This paper proposes a method to estimate the fission fractions for a specific reactor based upon publicly available information and provides a database based upon a series of spent fuel inventory calculations using the FISPIN10 code and its associated data libraries

Molecular basis of hereditary C1q deficiency-revisited: identification of several novel disease-causing mutations
C1q is the central pattern-recognition molecule in the classical pathway of the complement system and is known to have a key role in the crossroads between adaptive and innate immunity. Hereditary C1q deficiency is a rare genetic condition strongly associated with systemic lupus erythematosus and increased susceptibility to bacterial infections. However, the clinical symptoms may vary. For long, the molecular basis of C1q deficiency was ascribed to only six different mutations. In the present report, we describe five new patients with C1q deficiency, present the 12 causative mutations described till now and review the clinical spectrum of symptoms found in patients with C1q deficiency. With the results presented here, confirmed C1q deficiency is reported in 64 patients from at least 38 families.
