Random cliques in random graphs [PDF]

open access: yes, 2018
We show that for each $r\ge 4$, in a density range extending up to, and slightly beyond, the threshold for a $K_r$-factor, the copies of $K_r$ in the random graph $G(n,p)$ are randomly distributed, in the (one-sided) sense that the hypergraph that they ...

Evidence for the reliability and validity, and some support for the practical utility of the two-factor Consideration of Future Consequences Scale-14 [PDF]

open access: yes, 2016
Researchers have proposed 1-factor, 2-factor, and bifactor solutions to the 12-item Consideration of Future Consequences Scale (CFCS-12). In order to overcome some measurement problems and to create a robust and conceptually useful two-factor scale the ...

High-throughput, quantitative analyses of genetic interactions in E. coli. [PDF]

open access: yes, 2008
Large-scale genetic interaction studies provide the basis for defining gene function and pathway architecture. Recent advances in the ability to generate double mutants en masse in Saccharomyces cerevisiae have dramatically accelerated the acquisition of

On the Complexity Landscape of Connected f-Factor Problems [PDF]

open access: yes, 2016
Given an n-vertex graph G and a function f:V(G) -> {0, ..., n-1}, an f-factor is a subgraph H of G such that deg_H(v)=f(v) for every vertex v in V(G); we say that H is a connected f-factor if, in addition, the subgraph H is connected.

Novel calibrations of virial black hole mass estimators in active galaxies based on X-ray luminosity and optical/NIR emission lines [PDF]

open access: yes, 2016
Accurately weigh the masses of SMBH in AGN is currently possible for only a small group of local and bright broad-line AGN through reverberation mapping (RM).

The Efficiency of the Assay for Haemopietic Colony Forming Cells [PDF]

open access: yes, 1970
The quantitative efficiency of the spleen colony assay in mice is discussed in the light of recent findings on the kinetics of colony forming cells. Arguments are presented showing that the f factor, the 2 hr CFU recovery fraction in the spleen, markedly

Performance characteristics of a new structured packing [PDF]

open access: yes, 2010
A new structured packing using carbon fibres, called Sepcarb® 4D, is presented. This packing has several attractive properties, such as high voidage (ε=94%) and high effective area (a=420 m2 m−3).

Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]

open access: yes, 2009
In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...

The Black Hole Mass Scale of Classical and Pseudo Bulges in Active Galaxies

open access: yes, 2014
The mass estimator used to calculate black hole (BH) masses in broad-line active galactic nuclei (AGNs) relies on a virial coefficient (the "$f$ factor") that is determined by comparing reverberation-mapped (RM) AGNs with measured bulge stellar velocity ...

Modeling reverberation mapping data II: dynamical modeling of the Lick AGN Monitoring Project 2008 dataset [PDF]

open access: yes, 2014
We present dynamical modeling of the broad line region (BLR) for a sample of five Seyfert 1 galaxies using reverberation mapping data taken by the Lick AGN Monitoring Project in 2008.
