Silver europium(III) polyphosphate

open access: yesActa Crystallographica Section E, 2009
Europium(III) silver polyphosphate, AgEu(PO3)4, was prepared by the flux method. The atomic arrangement is built up by infinite (PO3)n chains (periodicity of 4) extending along the c axis. These chains are joined to each other by EuO8 dodecahedra. The Ag+

Dual affine translation surfaces in 3-dimensional simply isotropic space I13

open access: yesAnnals of the Alexandru Ioan Cuza University - Mathematics
In this paper, we study dual affine translation surfaces in the 3-dimensional simply isotropic space I1 3. We obtain the classification results for dual affine translation surfaces with constant dual isotropic Gaussian curvature or constant dual isotropic mean curvature.

Associations of Cumulative Burden of Prehypertension, Prediabetes and Predyslipidemia With All‐Cause and Cardiovascular Disease Mortality: A Retrospective Cohort Study

open access: yesThe Journal of Clinical Hypertension, Volume 28, Issue 5, May 2026.
ABSTRACT We aimed to examine the individual and combined impact of prehypertension, prediabetes, and predyslipidemia on all‐cause and cardiovascular disease (CVD) mortality in community‐dwelling adults. A retrospective cohort study of 11 986 US adults from the 1999–2018 National Health and Nutrition Examination Survey was conducted.

SAS Macros for Analysis of Unreplicated 2^k and 2^(k-p) Designs with a Possible Outlier

open access: yesJournal of Statistical Software, 2008
Many techniques have been proposed for judging the significance of effects in unreplicated 2^k and 2^(k-p) designs. However, relatively few methods have been proposed for analyzing unreplicated designs with possible outliers.

Why are there more accidents on Mondays? Economic incentives, ergonomics or externalities

open access: yesFrontiers in Behavioral Economics
IntroductionResearch consistently finds more workplace injuries occur on Mondays than on other weekdays. One hypothesis is that workers fraudulently claim that off-the-job weekend sprains and strains occurred at work on the Monday in order to receive ...

tmle : An R Package for Targeted Maximum Likelihood Estimation

open access: yesJournal of Statistical Software, 2012
Targeted maximum likelihood estimation (TMLE) is a general approach for constructing an efficient double-robust semi-parametric substitution estimator of a causal effect parameter or statistical association measure. tmle is a recently developed R package

FIAR: An R Package for Analyzing Functional Integration in the Brain

open access: yesJournal of Statistical Software, 2011
Functional integration in the brain refers to distributed interactions among functionally segregated regions. Investigation of effective connectivity in brain networks, i.e, the directed causal influence that one brain region exerts over another region ...

ipw: An R Package for Inverse Probability Weighting

open access: yesJournal of Statistical Software, 2011
We describe the R package ipw for estimating inverse probability weights. We show how to use the package to fit marginal structural models through inverse probability weighting, to estimate causal effects.
