Quantification of Segregation in Portland Cement Concrete Based on Spatial Distribution of Aggregate Size Fractions

Image Analysis and Stereology, 2020
Segregation is one of the quality standards that must be monitored during the fabrication and placement of Portland cement concrete. Segregation refers to separation of coarse aggregate from the cement paste, resulting in inhomogeneous mixture.

Capturing the two dimensions of residential segregation at the neighborhood level for health research

Frontiers in Public Health, 2014
Two conceptual and methodological foundations of segregation studies are that (i) segregation involves more than one group, and (ii) segregation measures need to quantify how different population groups are distributed across space. Therefore, percentage

Relationship Between Health Care Team Segregation and Receipt of Care by a Cardiologist According to Patient Race in a Midwestern State

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Segregation index (SI) has been associated with worsened health. However, the relationship between SI within health care teams (degree of heterogeneity between teams caring for Black compared with White patients) and cardiovascular care is ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The invariance properties of the mutual information index of multigroup segregation [PDF]

, 2009
In the context of educational segregation by ethnic group, it has been argued that rigorous pair wise segregation comparisons over time or across space should be invariant in two situations: when the ethnic composition of the population changes while the distribution of each ethnic group over the schools remains constant (invariance 1 ...

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Association between clinician team segregation, receipt of cardiovascular care and outcomes in valvular heart diseases

ESC Heart Failure
Aims Racial disparities exist in clinical outcomes for valvular heart disease (VHD). It is unknown whether clinician segregation contributes to these disparities.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Machine Learning Prediction of Surface Segregation Energies on Low Index Bimetallic Surfaces

Energies, 2020
Surface chemical composition of bimetallic catalysts can differ from the bulk composition because of the segregation of the alloy components. Thus, it is very useful to know how the different components are arranged on the surface of catalysts to gain a ...
