Determining cell-type abundance and expression from bulk tissues with digital cytometry
Nature Biotechnology, 2019 Single-cell RNA-sequencing has emerged as a powerful technique for characterizing cellular heterogeneity, but it is currently impractical on large sample cohorts and cannot be applied to fixed specimens collected as part of routine clinical care.

Nebular Abundance Errors [PDF]
, 1997 The errors inherent to the use of the standard "ionization correction factor" ("i_CF") method of calculating nebular conditions and relative abundances of H, He, N, O, Ne, S, and Ar in emission line nebulae have been investigated under conditions typical

Genome Biology, 2016 We introduce the Microenvironment Cell Populations-counter (MCP-counter) method, which allows the robust quantification of the absolute abundance of eight immune and two stromal cell populations in heterogeneous tissues from transcriptomic data.

Interstellar Extinction and Elemental Abundances [PDF]
, 2020 Elements in the interstellar medium (ISM) exist in the form of gas or dust. The interstellar extinction and elemental abundances provide crucial constraints on the composition, size and quantity of interstellar dust. Most of the extinction modeling efforts have assumed the total abundances (both in gas and in dust) of the dust-forming elements---known ...

Abundance of Lacewing, Glenochrysa sp. (Neuroptera: Chrysopidae) in Forest at Various Stages of Recovery after Logging at Sungai Lalang Forest Reserve, Selangor, Malaysia [PDF]
, 2007 A study on the abundance lacewing Glenochrysa sp. (Neuroptera:Chrysopidae) in a lowland dipterocarp forest at different stages of recovery after longing was carried out. The lacewings were sampled using sticky traps baited with eugenol.

Normalization and microbial differential abundance strategies depend upon data characteristics
Microbiome, 2017 BackgroundData from 16S ribosomal RNA (rRNA) amplicon sequencing present challenges to ecological and statistical interpretation. In particular, library sizes often vary over several ranges of magnitude, and the data contains many zeros.

Chemical Abundances in our Galaxy and Other Galaxies Derived from H II Regions [PDF]
Astrophys.Space Sci. 277 (2001) 147-156, 2000 We discuss the accuracy of the abundance determinations of H II regions in our Galaxy and other galaxies. We focus on the main observational constraints derived from abundance determinations that have implications for models of galactic chemical evolution: a) the helium to hydrogen abundance ratio, He/H; b) the oxygen to hydrogen abundance ratio, O/H ...

An Abundance of Heterotic Vacua [PDF]
, 2008 We explicitly construct the largest dataset to date of heterotic vacua arising from stable vector bundles on Calabi-Yau threefolds. Focusing on elliptically fibered Calabi-Yau manifolds with spectral cover bundles, we show that the number of heterotic ...

Natural Resource Abundance and Economic Growth
, 1995 One of the surprising features of modern economic growth is that economies with abundant natural resources have tended to grow less rapidly than natural-resource-scarce economies. In this paper we show that economies with a high ratio of natural resource
