Medical Image Analysis, 2006 The process of constructing an atlas typically involves selecting one individual from a sample on which to base or root the atlas. If the individual selected is far from the population mean, then the resulting atlas is biased towards this individual. This, in turn, can bias any inferences made with the atlas.

The stratification of cirrhosis [PDF]
Hepatology Research, 2020 Cirrhosis is traditionally seen as an irreversible stage of chronic liver disease although its clinical course may last several years. Overall, the clinical management of patients with cirrhosis is based on the observation of clinical events mostly related to complications of portal hypertension.

The stratification of rigidity [PDF]
Journal of High Energy Physics, 2022 Abstract We show that a master integrand basis exists for all planar, two-loop amplitudes in massless four-dimensional theories which is fully stratified by rigidity — with each integrand being either pure and strictly polylogarithmic or (pure and) strictly elliptic-polylogarithmic, with each of the later involving a single ...

On adaptive stratification [PDF]
Annals of Operations Research, 2009 This paper investigates the use of stratified sampling as a variance reduction technique for approximating integrals over large dimensional spaces. The accuracy of this method critically depends on the choice of the space partition, the strata, which should be ideally fitted to thesubsets where the functions to integrate is nearly constant, and on the ...

Migration and Stratification [PDF]
Social Science Research, 2011 Migration and stratification are increasingly intertwined. One day soon it will be impossible to understand one without the other. Both focus on life chances. Stratification is about differential life chances who gets what and why and migration is about improving life chances getting more of the good things of life.

Income stratification and between-group inequality [PDF]
, 2013 The paper shows explicitly how the overlapping of groups impacts between-group inequality by generalizing a result on the group-wise decomposition of the Gini index to more than two groups.

Stratifications on the Ran Space [PDF]
Order, 2021 AbstractWe describe a partial order on finite simplicial complexes. This partial order provides a poset stratification of the product of the Ran space of a metric space and the nonnegative real numbers, through the Čech simplicial complex. We show that paths in this product space respecting its stratification induce simplicial maps between the ...

Impacts of morphological change and sea-level rise on stratification in the Pearl River Estuary
Frontiers in Marine Science, 2023 The Pearl River Delta (PRD), where several megacities are located, has undergone drastic morphological changes caused by anthropogenic impact during the past few decades.

Who Gets Accepted and Who Gets Rejected? Status in the Production of Social Science
RSF: The Russell Sage Foundation Journal of the Social Sciences, 2022 This article considers science as a stratified social system that may reflect and reproduce broader social patterns of stratification. Analyses are based on a unique data archive with more than ten thousand published and unpublished manuscripts and the ...
