Three syenite dike sets, named the Santa Cruz dikes, are coeval with the 627 ± 13 Ma old porphyritic calc-alkalic Princesa Izabel granitoid, northeastern Brazil. Dike set 1 is up to 1.5 m wide, strike 030 e040 Az, roughly parallel to the regional foliation. Dike set 2 strikes 120 e130 Az and consists of xenolith-bearing syenites and is roughly parallel to dike set 3, which is up to 1.5 m wide a...

BACKGROUND Within-person variability in measured values of a risk factor can bias its association with disease. We investigated the extent of regression dilution bias in calculated variables and its implications for comparing the aetiological associations of risk factors. METHODS Using a numerical illustration and repeats from 42,300 individuals (12 cohorts), we estimated regression dilution ...

A Monte Carlo computer program has been used to calculate characteristics of the response of fully depleted silicon and germanium radiation detectors to monoenergetic gamma rays. Data for total absorption probability, intrinsic efficiency, escape peak efficiency and pulse height spectra are presented as functions of detector thickness and photon energy. Other parameters of interest in analysing...

We performed a first-principle, computational study of the optical properties of ruthenium dioxide. Our method employed a local density potential and the linear combination of atomic orbitals (LCAO). We circumvented a recently discovered spurious effect that is inherently associated with basis sets in variational calculations of the Rayleigh-Ritz type. Consequently, a significantly new feature ...

AIM Cardiovascular disease is the major cause of morbidity and mortality across the world. Despite health campaigns to improve awareness of cardiovascular risk factors, there has been little improvement in cardiovascular mortality. In this study, we sought to examine the association between cardiovascular risk factors and people's perception on cardiovascular risk. METHODS This was an epidemi...

AIMS Elevated non-fasting triglycerides mark elevated levels of remnant cholesterol. Using a Mendelian randomization approach, we tested whether genetically increased remnant cholesterol in hypertriglyceridaemia due to genetic variation in the apolipoprotein A5 gene (APOA5) associates with an increased risk of myocardial infarction (MI). METHODS AND RESULTS We resequenced the core promoter an...
