On the Mass-to-Light Ratio of Large Scale Structure [PDF]
The Astrophysical Journal, 2004 We examine the dependence of the mass-to-light (M/L) ratio of large-scale structure on cosmological parameters, in models that are constrained to match observations of the projected galaxy correlation function w(rp). For a sequence of cosmological models

INTERVAL ESTIMATION FOR THE RATIO OF SCALE PARAMETERS AND FOR ORDERED SCALE PARAMETERS [PDF]
Statistics & Risk Modeling, 2000 Summary: Confidence intervals for the ratio of scale parameters are constructed in general families of distributions with nuisance (location) parameters. Each of these intervals has coverage probability at least as large as that of the standard minimum size (i.e., minimum ratio of endpoints) interval and, in addition, smaller size.

The diagnostic value of the ultrasound gray scale ratio for different sizes of thyroid nodules [PDF]
Cancer Medicine, 2019 At present, hypoechogenicity, as one of the clinically relevant features associated with suspicion of malignant thyroid disease, is affected by the variability of modules and the experience of sonographers, thus leading to unsatisfying results.

Determining drivers of phytoplankton carbon to chlorophyll ratio at Atlantic Basin scale
Frontiers in Marine Science, 2023 We demonstrate the ability of flow cytometry to determine species specific cellular carbon and chlorophyll content in vivo by using laboratory cultures of phytoplankton encompassing a wide range of cell sizes.

The mass-to-charge ratio scale [PDF]
Journal of the American Society for Mass Spectrometry, 1994 Increases in the capacity for accurately measuring the mass-to-charge ratio of specific gas-phase ions justify the reconsideration and standard definition of the gas-phase mass-to-charge ratio scale and the clearly denned connection of that scale to condensed phases.

Sequential Probabilistic Ratio Test for the Scale Parameter of the P-Norm Distribution
Discrete Dynamics in Nature and Society, 2021 We consider a series of independent observations from a P-norm distribution with the position parameter μ and the scale parameter σ. We test the simple hypothesis H0:σ=σ1 versus H1: σ=σ2.

Performance Ratio Analysis Based on Energy Production for Large-Scale Solar Plant
IEEE Access, 2022 This paper presents an industrial approach to assess the performance of large-scale solar plants (LSSPs) has been developed using a novel performance ratio (PR) formula model based on energy production.
