b MA-XRF maps showing the repartition of Zn, Ba (L-rays), Cd (K-rays), Hg (L rays) and Pb (L and M rays) elements in the overall painting.
Biorthogonal Fourier transform (BFT), consistent with the matched signal transform (MST), has been introduced to demodulate the M-ray chirp-rate signal which possesses good orthogonality in the BFT domain.
The high-resolution von Hamos Bragg crystal spectrometer was constructed for the study of K X-ray emission from low-Z elements and L and M X-ray spectra of medium to high Z elements.
We consider the problem of exploring m concurrent rays using a searcher.
In this paper we show that depth-first iterative deepening (DFID) strategies are optimal for an agent searching in a line, in m concurrent rays, and in uniform b-ary trees.
In contrast, as the concentration was increased above 0.01 M, X-ray attenuation by Au DENPs became progressively greater than that of the corresponding iohexol solution.
All radiographs of the hand were acquired by a Siemens Multix Polymat equipment (Siemens AG, Erlangen, Germany) (AGFA Curix film; film focus distance, 1 m; X-ray tube voltage, 55 kV; exposure dose, 6 mAs).
16 h later, cells were starved in serum-free media for 4 h, then stimulated for 3 h, and irradiated using the Faxitron at a distance of 0.33 m x-ray source for 1.1, 2.2, or 3.3 min (for 2, 4, 6 Gy, respectively).
Under these conditions, for each constant s the numbers (lambda_{sjn}=ialpha_{n} ( omega_{j}-omega_{s} ) ^{-1}), (nin mathbb{N}), (j=1,2,ldots,m), (jneq s), are located on the (m-1) rays from the origin.
The CT acquisition consisted of 120 projections acquired with exposure time of 200 ms, X-ray voltage of 80 kVp and anode current of 500 μA for 220° rotation.
