[1] Lightning type identification of temporally coincident optical-VHF time series event pairs collected by the Fast On-orbit Recording of Transient Events (FORTE) satellite’s photodiode detector (PDD) and VHF instrument allows for the investigation of optical properties as a function of lightning type. General trends in the peak optical irradiance and characteristic pulse widths of PDD-VHF coi...
We examined the effects of aging and hypertensive left ventricular hypertrophy on the plasma level of brain natriuretic peptide (BNP), and assessed BNP as a risk marker for incident hypertensive cardiovascular events. One hundred and eighty-five hypertensive patients were echocardiographically divided into a hypertensive group with normal left ventricular mass (n=96; age range, 37-86 years; lef...
Brachial-ankle elasticity index (baEI; also known as brachial-ankle pulse wave velocity) has been proposed as a surrogate end point for cardiovascular disease. We performed a meta-analysis of longitudinal cohort studies for determining the ability of baEI to predict risk of cardiovascular events and all-cause mortality and dissecting factors influencing this predictive ability. Multiple online ...
Air showers from cosmic rays emit short, intense radio pulses. LOFAR is a new radio telescope, that is being built in the Netherlands and Europe. Designed primarily as a radio interferometer, the core of LOFAR will have a high density of radio antennas, which will be extremely well calibrated. This makes LOFAR a unique tool for the study of the radio properties of single air showers. Triggering...

We present here by direct argument the classical Clopper-Pearson (1934) “exact” confidence bounds and corresponding intervals for the parameter p of the binomial distribution. The same arguments can be applied to derive confidence bounds and intervals for the negative binomial parameter p, for the Poisson parameter λ, for the ratio of two Poisson parameters, ρ = λ1/λ2, and for the parameter D o...
Set-point theory posits that individuals react to the experience of major life events, but quickly adapt back to pre-event baseline levels of subjective well-being in the years following the event. A large, nationally representative panel study of Swiss households was used to examine set-point theory by investigating the extent of adaptation following the experience of marriage, childbirth, wid...
Retention is thought to be a crucial component required create favourable habitat for coastal pelagic species. It vital the survival of ‘chokka’ squid (Loligo reynaudii), which fishery that supports thousands people living in Eastern Cape South Africa. After chokka spawn, retention on Agulhas Bank prevent starvation early life stages. Using high-resolution ocean model, this study quantifies pro...
