The invention is in concern of an arrangement for producing artificial rainbows, particularly for use in planetaria, in which a bundle of light emitted from a light source and directed through an aperture upon a prism is dispersed by the latter and reflected at a cylindrical reflector. Due to ...
For instance, in neuroscience the activity of the cell body of a neuron can interact with synaptic activity which can be directly affected by gliomes in the presence of brain tumors44. In order to shed light on the possible phase transitions that can occur when topological signals defined on...
A spectral decomposition of the variable optical, ultraviolet and X‐ray continuum of NGC 5548 We present an analysis and decomposition of the broad-band optical/UV/X-ray/-ray spectrum of the Seyfert 1 galaxy NGC 5548. The spectrum consists of an ave... M Paweł,OM Blaes,AA Zdziarski,...
For spectrally-resolved measurements, we send part of the FH light to the optical spectrum analyzer. We calibrate the fiber-to-chip coupling efficiency based on power transmission measurements and fits of theoretical models to nonlinear response data (see “Methods”). The typical edge coupling ...

This includes source spectrum, X-ray projection through digitized 3D object phantom, detector gain, noise and system blur. The models account for blurring effects due to both the focal-spot and the scintillator component of the detector. The detector in this study was modeled as a CsI (0.1 ...
