The Flatness of Mass-to-Light Ratio on Large Scales [PDF]
The Astrophysical Journal, 1999 It has been suggested that the mass-to-light ($M/L$) ratio of gravitationally clustering objects is scale-independent on scales beyond galaxy clusters, and may also be independent of the mass of the objects. In this paper, we show that the scale behavior of $M/L$ ratio is closely related to the scaling of cosmic structures larger than clusters.

The diagnostic value of the ultrasound gray scale ratio for different sizes of thyroid nodules. [PDF]
Cancer Med, 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.

Using Spectral Radius Ratio for Node Degree to Analyze the Evolution of Scale Free Networks and Small World Networks [PDF]
, 2015 In this paper, we show the evaluation of the spectral radius for node degree as the basis to analyze the variation in the node degrees during the evolution of scale-free networks and small-world networks. Spectral radius is the principal eigenvalue of the adjacency matrix of a network graph and spectral radius ratio for node degree is the ratio of the ...

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

An accurate bound on tensor-to-scalar ratio and the scale of inflation [PDF]
, 2014 In this paper we provide an accurate bound on primordial gravitational waves, i.e. tensor-to-scalar ratio $(r)$ for a general class of single-field models of inflation where inflation occurs always below the Planck scale, and the field displacement ...

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.

A scale of interpretation for likelihood ratios and Bayes factors [PDF]
PLoS ONE 19(2): e0297874 (2024), 2022 Several subjective proposals have been made for interpreting the strength of evidence in likelihood ratios and Bayes factors. I identify a more objective scaling by modelling the effect of evidence on belief. The resulting scale with base 3.73 aligns with previous proposals and may partly explain intuitions.
