This article provides an overview of neonatal intensive care unit (NICU) treatment costs. It discusses data sources as well as the methods for measuring costs, contrasting the strengths and weaknesses of alternate approaches. In addition, detailed information on NICU treatment costs is presented from a nationally representative sample of 25 hospitals with NICUs. The sample consists of 3288 very...

Patients with active interstitial lung disease (ILD) are often treated with high-dose corticosteroids, although such therapy is not universally effective and has significant risks. Clinicians have utilized various ancillary diagnostic techniques to help with difficult treatment decisions. Since magnetic resonance imaging (MRI) has the theoretic and experimental potential of differentiating vari...

SUMMARY For a variable and parameter of the same dimension, the tangent exponential model (Fraser, 1988) approximates an asymptotic model to third order in a rst derivative neighbourhood of the data point and to second order otherwise. For the more usual case of a variable of larger dimension than the parameter, we obtain a unique expression for the third order ancillary distribution as project...

The clinical diagnosis of dementia includes medical history, neurological examination, psychiatric interview and dementia scale. The identification of conditions producing dementia can only be achieved by adding to the clinical information the data gathered from ancillary investigations. The usual ancillary diagnostic investigations (biochemical tests, cerebrospinal fluid (CSF), EEG, CT, MRI, a...

High resolution, contemporary data on human population distributions are vital for measuring impacts of population growth, monitoring human-environment interactions and for planning and policy development. Many methods are used to disaggregate census data and predict population densities for finer scale, gridded population data sets. We present a new semi-automated dasymetric modeling approach ...

Assembly of genomic sequences and maps relies on a primary set of experimental data (e.g., the sequences of individual DNA fragments, or hybridization fingerprints of individual clone inserts), but almost always also relies on several streams of related but distinct kinds of data for completeness and accuracy of the final construction. These secondary data sets, which we term ancillary informat...

This study assessed the suitability of both visible and shortwave infrared ASTER data and vegetation indices for estimating forest structural attributes of Eucalyptus species in the southern KwaZulu Natal, South Africa. The empirical relationships between forest structural attributes and ASTER data were derived using stepwise multiple regression analysis; Modified Soil Adjusted Vegetation Index...
