The genome of the human hepatitis delta virus (HDV) harbors a self-cleaving catalytic RNA motif, the genomic HDV ribozyme, whose crystal structure shows the dangling nucleotides 5' of the cleavage site projecting away from the catalytic core. This 5'-sequence contains a clinically conserved U-1 that we find to be essential for fast cleavage, as the order of activity follows U-1 > C-1 > A-1 > G-...

The Diamond booster and storage ring are equipped with Libera Electron Beam Position Processors with turnby-turn capabilities. We describe here the turn-by-turn data acquisition system and the software used for postprocessing the beam data. The signals from the Libera boxes are acquired and controlled with EPICS and then transferred to the MATLAB environment via the MATLAB Channel Access or Lab...

A turn-by-turn vertical beam profile monitor has been developed at the Cornell Electron Storage Ring (CESR). The instrument optically images the vertical beam distribution with an array of optical fibers that transport visible synchrotron radiation to an array of photo-multiplier tubes. Each PMT signal is recorded by a turn-by-turn data acquisition system. With this instrument, we compare profi...

We prove the existence of a solution for the nonlinear boundary value problem u = f ( x, u, u′′, . . . , u ) , x ∈ [0, 1], u(0) = 0 = u(1), 0 ≤ i ≤ m + 1, where f : [0, 1] × R → R is continuous. The technique used here is a monotone method in the presence of upper and lower solutions. We introduce a new maximum principle which generalizes one due to Bai which in turn was an improvement of a max...

The complete coverage path planning algorithm based on A* algorithms for the cleaning robot in known environment is proposed in this paper, which uses A* algorithm as heuristic in the U-turn search algorithm. The idea of this algorithm is the cleaning robot clean the cleaning area from the point of origin by using U-turn algorithm, then planning of the shortest path from cleaning robot to not c...
