To see the effects of the direct X-ray in a Lanex screen-coupled CMOS APS imager, we measured modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). These measurements were performed under the condition of non-destructive test (NDT). By increasing the cumulative exposure on the imager, the MTF was degraded, and also leading to the DQE degradation...

Abstract Redshift evolution and peculiar velocities break the isotropy of cosmological surveys with respect to directions parallel transverse line sight, limiting accuracy Fourier representation small areas redshift ranges. In contrast space power spectrum, full information about two-point function tracers large-scale structure is encapsulated in redshift-dependent angular spectrum C ij ℓ ( z i...

The amplitude of the second peak in the angular power spectrum of the cosmic microwave background radiation is constrained to be small by recent experiments like Boomerang. This is surprising in the context of the ΛCDM model, which predicted a large second peak. However, this result is expected if CDM does not exist. The observed shape of the power spectrum was accurately predicted (before the ...

In the previous study, the author has proposed a simplified propagation modeling and a performance evaluation scheme of MIMO antennas, which utilizes the ideal base-station antenna configuration so that the angular power spectrum model for the user terminal is applicable for Kronecker MIMO model. By utilizing this modeling concept, this paper considers the impact of the concentrated azimuth pow...

We describe the angular power spectrum of unresolved 3.6 μm IR light in Spitzer GOODS fields. The amplitude of the anisotropy spectrum decreases with decreasing flux threshold to which resolved sources are removed from images. When all pixels brighter than a Vega magnitude of 24.6 are removed, the amplitude of the power spectrum at arcminute angular scales can be described with an extra compone...

We study the inflation process of universe based on the renormalizable quantum gravity formulated as a conformal field theory (CFT). We show that the power-law CFT spectrum approaches to that of the Harrison-Zel’dovich-Peebles type as the amplitude of gravitational potential gradually reduces during the inflation. The non-Gaussanity parameter is preserved within order of unity due to the diffeo...
