It has been shown that the Fourier analysis of recorded turn–by–turn tracking data can be used to derive resonance terms of an accelerator. Beside the resonance driving terms, the non–linear one–turn map can be obtained with all non–linearities arising from magnetic imperfections and correction elements. This could be interesting for the LHC which will be a machine dominated by strong non–linea...

Eukaryotes have hundreds (sometimes thousands) of ribosomal RNA (rRNA) genes whose transcription by RNA polymerase I helps establish the proliferative ability of cells by dictating the pace of ribosome production and protein synthesis. Interestingly, only a subset of the total rRNA gene pool is active at any one time, making rRNA genes attractive for understanding the dynamic balance between ge...
