Rare metal resources with uneven distribution.

Uneven distribution of light in standard phototherapy.

Maldistribution of light is a potential cause of phototherapy failure in the neonate. Differences in light intensity over the surface can be measured with a radiometer as this detects the radiant energy impinging on the incubator mattress. An infant nursed on the front third of the mattress receives less than 40% of the maximal light incident on the centre of the mattress, and consequently degr...

Rare gas collisions with molten metal surfaces.

Newly available experimental data for the scattering of argon, neon, and xenon atoms from molten gallium, indium, and bismuth surfaces are compared to calculations with classical scattering theory. The results of the theory are in reasonable agreement with observed energy-resolved spectra taken at fixed angles, with in-plane angular distributions, and with the first available out-of-plane angul...

Evaluation of Classifiers for an Uneven Class Distribution Problem

Classification problems with uneven class distributions present several difficulties during the training as well as during the evaluation process of classifiers. A classification problem with such characteristics has resulted from a data-mining project where the objective was to predict customer insolvency. Using the dataset from the customer insolvency problem we study several alternative meth...

Uneven global distribution of randomized trials in hip fracture surgery

BACKGROUND AND PURPOSE Hip fractures are among the top causes of global disability. Conduction of high-quality studies such as randomized controlled trials to assess the effectiveness of interventions remains crucial. The geographic distribution of hip fracture studies is largely unknown. We wanted to make a global assessment of national contributions of randomized controlled trials on surgical...
