Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform ...

Sample size calculations for a continuous outcome require specification of the anticipated variance; inaccurate specification can result in an underpowered or overpowered study. For this reason, ...

This article discusses reduced sampling and testing of starting materials or components. Different strategies are presented to reduce the workload at the steps from sampling to release. Viewpoints ...

Selecting a random sample from a set is simple. But what about selecting a fair random sample from a set of unknown or indeterminate size? That’s where reservoir sampling comes in, and [Sam Rose] has ...

Stable isotope techniques can help identify the sources of water pollution associated with agricultural activities. Knowing the origin of nutrients or contaminants is essential to improve agricultural ...
