The Dust Attenuation Law in Galaxies [PDF]
Understanding the properties of dust attenuation curves in galaxies and the physical mechanisms that shape them are among the fundamental questions of extragalactic astrophysics, with great practical significance for deriving the physical properties of ...

Dust Attenuation Curves in the Local Universe: Demographics and New Laws for Star-forming Galaxies and High-redshift Analogs [PDF]
We study the dust attenuation curves of 230,000 individual galaxies in the local universe, ranging from quiescent to intensely star-forming systems, using GALEX, SDSS, and WISE photometry calibrated on the Herschel ATLAS.

Predicting Depth of Mineral Deposit using Gravity-Density Downward Correlation by Fourier Transform
Residual gravity anomalies are the superposition of effects originating from several interfaces in the subsurface. In downward projection of the anomalies for the determination of the depth of the particular substructure which accounts for the bulk of ...

Attenuated Psychosis Syndrome [PDF]
Byline: M. Reddy Diagnostic and Statistical Manual of Mental Disorders, 5 [sup]th edition (DSM - 5) included attenuated psychosis syndrome (APS) in Section III under "conditions for further study". The DSM - 5 task force determined that there was insufficient evidence to warrant inclusion of APS as official mental disorder diagnosis in Section II. "The

Attenuation correction in SPECT without attenuation map [PDF]
A method of attenuation correction in Single Photon Emission Computed Tomography (SPECT), based on emission data only is presented. The algorithm uses the well known Helgason-Ludwig consistency conditions. However, it does not attempt to find the attenuation map, but rather the correction factors for the projection data, which makes the problem simpler
