By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

Optimizing fusion bead preparation techniques is crucial for high-precision XRF analysis, improving calibration stability and ...

We revisit the problem of determining the sample size for a Gaussian process emulator and provide a data analytic tool for exact sample size calculations that goes beyond the n = 10d rule of thumb and ...

Pew Research Center designed this study to assess the current state of online survey sampling methods – both probability-based and opt-in – and determine their accuracy on general population estimates ...

In the first part of this piece I pointed out why it can be difficult to validate TAR using control set metrics. When the overall proportion of responsive documents is very low, it becomes ...

Implementing efficient crushing and pulverizing protocols in XRF labs is crucial for achieving precise, contamination-free ...
