TL;DR: The axion-photon coupling strength of the CERN Axion Solar Telescope (CAST) was shown to be at least 0.02$ eV in the first vacuum phase (2003-2004) with low-background x-ray detectors and a new xray telescope as mentioned in this paper.
Journal ArticleDOI
Morphological waveform coding for writer identification
TL;DR: Both Bayesian classifiers and neural networks are employed to test the efficiency of the proposed feature and the achieved identification success using a long word exceeds 95%.

TL;DR: A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of 10-29 e ⋅ cm by using polarized "magic" momentum 0.7 GeV/c protons in an all-electric storage ring.
Journal ArticleDOI
Optimal CFAR detection in Weibull clutter
TL;DR: In this article, an asymptotically efficient estimator of the mean power of the Weibull clutter was proposed for constant false-alarm rate (CFAR) detection.
Journal ArticleDOI
A multiple projection method for digital tomosynthesis.
TL;DR: A new method of optimized efficiency for the retrospective reconstruction of tomograms is presented, achieved by segmenting the reconstruction process into discrete transformations that are specific to groups of pixels, rather than performing pixel by pixel operations.
