The HectoMAP Cluster Survey - I. redMaPPer Clusters [PDF]
, 2018 We use the dense HectoMAP redshift survey to explore the properties of 104 redMaPPer cluster candidates. The redMaPPer systems in HectoMAP cover the full range of richness and redshift (0.08 $< z

The Journal of Economic Inequality, 2013 An index of richness in a society is a measure of the extent of its affluence. This paper presents an analytical discussion on several indices of richness and their properties. It also develops criteria for ordering alternative distributions of income in terms of their richness. Given a line of richness, an income level above which a person is regarded

Proceedings of the American Mathematical Society, 1980 Let ( V = L ) α {(V = L)_\alpha } say that every bounded subset of α \alpha is an element of L α {L_\alpha } . We show that if ( V = L ) α

Mammal predator and prey species richness are strongly linked at macroscales [PDF]
, 2013 Predator-prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large-scale gradients of species richness remains unexplored.

Fire Effects on Understory Forest Regeneration in Southern Amazonia
Frontiers in Forests and Global Change, 2020 Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks. Currently, there are large gaps in understanding how fire affects understory forest structure and composition, interactions with fire recurrence, and

Making the observational parsimonious richness a working mass proxy [PDF]
, 2015 Richness, i.e., the number of bright cluster galaxies, is known to correlate with the cluster mass, however, to exploit it as mass proxy we need a way to estimate the aperture in which galaxies should be counted that minimizes the scatter between mass ...

Mass-Richness relations for X-ray and SZE-selected clusters at $0.4 < z <2.0$ as seen by $Spitzer$ at 4.5$\mu$m [PDF]
, 2017 We study the mass-richness relation of 116 spectroscopically-confirmed massive clusters at $0.4 < z < 2$ by mining the $Spitzer$ archive. We homogeneously measure the richness at 4.5$\mu$m for our cluster sample within a fixed aperture of $2^{\prime ...

Generalized Thue-Morse words and palindromic richness [PDF]
, 2011 We prove that the generalized Thue-Morse word $\mathbf{t}_{b,m}$ defined for $b \geq 2$ and $m \geq 1$ as $\mathbf{t}_{b,m} = (s_b(n) \mod m)_{n=0}^{+\infty}$, where $s_b(n)$ denotes the sum of digits in the base-$b$ representation of the integer $n ...

Vegetation Analysis in Community Forests of Terai Region, Nepal
International Journal of Environment, 2019 This paper deals with the study of vegetation analysis of tree species in Ganesh and Ramnagar community forests (CF) of the Terai region. For the study, altogether 63 concentric sample plots (each plot of 500 m2) were laid using systematic sampling with

Using abundance data to assess the relative role of sampling biases and evolutionary radiations in Upper Muschelkalk ammonoids [PDF]
, 2011 The Middle Triassic ammonoid genus Ceratites diversified spectacularly within the Germanic Muschelkalk Basin during the Anisian/Ladian (244–232 Mya). Previous studies have interpreted this diversification as a sequence of rapid, endemic radiations from a
