We calculate conformal anomalies in noncommutative gauge theories by using path integral method (Fujikawa’s method). As well as the axial anomalies and chiral gauge anomalies, the conformal anomalies take the form of the straightforward Moyal deformation in the corresponding conformal anomalies in ordinary gauge theories. However, Moyal star product leads the difference in the coefficient of th...

[1] The ratio of monthly median foF2 values between the ionosondes at Maui (20.8 N, 156 E geographic; 21.2 N, 90.4 E geomagnetic) and Yamagawa (31.2 N, 130.6 E geographic; 20.6 N, 160.9 E geomagnetic) from January 1960 to June 1993 are used to investigate interannual variability in the wave-4 longitudinal structure of the low-latitude F region ionosphere. Analysis of Global Positioning System t...

X-linked recessive ocular albinism type I (OA1) is due to mutations in the OA1 gene (approved gene symbol GPR143), which is expressed in the retinal pigment epithelium (RPE). The Oa1 (Gpr143) knockout mouse (Oa1(-/-)) model recapitulates many of the OA1 retinal morphological anomalies, including a lower number of melanosomes of increased size in the RPE. The Oa1(-/-) mouse also displays some of...

S U M M A R Y Lateral variations in mantle anelasticity (Q) are important for understanding the Earth’s thermal and chemical structure in the mantle. In the past decades, preliminary global 3-D tomographic Q models have been developed based upon the assumption that traveltime (phase delay) anomalies are due to the Earth’s elastic (velocity) structure whereas amplitude anomalies are dominated by...

In this study we examine the possibility that the historical total of human landcover changes have had a comparable effect on climate to that of historical increases in CO2 and aerosols. We compared results from two coupled climate model simulations which investigated transient climate changes produced by observed historical changes of CO2 combined with sulfate aerosol forcing with two other cl...

We present N abundances for 21 bright giants in the globular cluster NGC 6752 based on high-resolution UVES spectra of the 3360Å NH lines. We confirm that the Strömgren c1 index traces the N abundance and find that the star-tostar N abundance variation is 1.95 dex, at the sample’s luminosity. We find statistically significant correlations, but small amplitude variations, between the abundances ...

The long-wavelength topography of Titan has an amplitude larger than that expected from tidal and rotational distortions at its current distance from Saturn. This topography is associated with small gravity anomalies, indicating a high degree of compensation. Both observations can be explained if Titan has a floating, isostatically-compensated ice shell with a spatially-varying thickness. The s...

The processing of Chirp data is limited by the usual recording signal envelope, which enhances its immediate visibility but prevents applying methods based on wave equations. This normally not case for Boomer data. However, both systems are monochannel instruments, cannot estimate properly propagation velocity in rocks. In this paper, we present two theorems: first one links or source spectrum ...
