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

The diagnostic value of the ultrasound gray scale ratio for different sizes of thyroid nodules
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.

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

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 ...

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.

Study of Creating Functional Disorder Ratio Scale for Locomotor System Restrictions
Adli Tıp Bülteni, 2021 Objective:The present study aims to emphasize the importance of evaluating locomotor system limitations in terms of functional impairment or loss in injury, traffic accident and occupational accident reports and to develop new scale evaluating percentage
