Congenital anomaly surveillance in England—ascertainment deficiencies in the national system
Description :
Objective Firstly, to assess the completeness of ascertainment in the National Congenital Anomaly System (NCAS), the basis for congenital anomaly surveillance in England and Wales, and its variation by defect, geographical area, and socioeconomic deprivation. Secondly, to assess the impact of the la...

Using decision analysis to compare policies for antenatal screening for Down's syndrome.
Description :
OBJECTIVE--To compare different screening policies for Down's syndrome across a broad range of outcomes, using decision analysis, with particular reference to the role of maternal serum testing. DESIGN--A decision tree was used to combine data from local sources and the medical literature to predict...

What is important to patients receiving extracorporeal shock-wave lithotripsy for urinary tract calculi?
Description :
INTRODUCTION: Patients' experience and expectations are paramount in the current era of clinical governance. However, there is lack of published information on patients' expectations from extracorporeal shock-wave lithotripsy (ESWL) treatment for renal stone disease. We conducted a survey to quantif...

Climate-mediated changes to mixed-layer properties in the Southern Ocean: assessing the phytoplankton response
Description :
Concurrent changes in ocean chemical and physical properties influence phytoplankton dynamics via alterations in carbonate chemistry, nutrient and trace metal inventories and upper ocean light environment. Using a fully coupled, global carbon-climate model (Climate System Model 1.4-carbon), we quant...

Description :
We present Keck II spectroscopy of an optical mHz quasi-periodic oscillations
(QPOs) in the lightcurve of the X-ray pulsar binary Her X-1. In the power
spectrum it appears as `peaked noise', with a coherency $\sim$2, a central
frequency of 35 mHz and a peak-to-peak amplitude of 5%. However, the dy...

Low Dimensional Dynamics in a Pulsating Star
Description :
We report the discovery of a low dimensional dynamical system in a 5.5 hr
Hubble Space Telescope High Speed Photometer observation of a rapidly
oscillating star. The topological description of the phase space orbits is
given, as well as a dynamical model which describes the results. This model
sho...
