MinInversion: A Program for Petrophysical Composition Analysis of Geophysical Well Log Data
Geosciences, 2018 Knowledge of the composition (mineral and fluid proportions) of rock formation lithologies is important for petrophysical and rock physics analysis. The mineralogy of a rock formation can be estimated by solving a system of linear equations that relate a

Do not log-transform count data [PDF]
, 2010 1. Ecological count data (e.g., number of individuals or species) are often log-transformed to satisfy parametric test assumptions. 2. Apart from the fact that generalized linear models are better suited in dealing with count data, a log ...

The Calibration of the WISE W1 and W2 Tully-Fisher Relation [PDF]
, 2014 In order to explore local large-scale structures and velocity fields, accurate galaxy distance measures are needed. We now extend the well-tested recipe for calibrating the correlation between galaxy rotation rates and luminosities -- capable of ...

A Correlation between Galaxy Light Concentration and Supermassive Black Hole Mass [PDF]
, 2001 We present evidence for a strong correlation between the concentration of bulges and the mass of their central supermassive black hole (M_bh) -- more concentrated bulges have more massive black holes.

The Structure of Stellar Coronae in Active Binary Systems [PDF]
, 2002 A survey of 28 stars using EUV spectra has been conducted to establish the structure of stellar coronae in active binary systems from the EMD, electron densities, and scale sizes. Observations obtained by the EUVE during 9 years of operation are included
