Quantitative estimation of sampling uncertainties for mycotoxins in cereal shipments [PDF]

, 2012
Many countries receive shipments of bulk cereals from primary producers. There is a volume of work that is ongoing that seeks to arrive at appropriate standards for the quality of the shipments and the means to assess the shipments as they are out-loaded.

Evaluation of respondent-driven sampling [PDF]

, 2012
Respondent-driven sampling produced a generally representative sample of this well-connected nonhidden population. However, current respondent-driven sampling inference methods failed to reduce bias when it occurred.

Acceptability of unsupervised HPV self-sampling using written instructions [PDF]

, 2006
Objectives The study measured the acceptability of self-sampling for human papillomavirus (HPV) testing in the context of cervical cancer screening. Women carried out self-sampling unsupervised, using a written instruction sheet.Setting Participants were

Intelligent sampling for the measurement of structured surfaces [PDF]

, 2012
Uniform sampling in metrology has known drawbacks such as coherent spectral aliasing and a lack of efficiency in terms of measuring time and data storage.

Mixture models for distance sampling detection functions [PDF]

, 2015
Funding: EPSRC DTGWe present a new class of models for the detection function in distance sampling surveys of wildlife populations, based on finite mixtures of simple parametric key functions such as the half-normal. The models share many of the features

Flexible frames and control sampling in case-control studies\ud [PDF]

, 2008
We propose two innovations in statistical sampling for controls to enable better design of population-based case-control studies. The main innovation leads to novel solutions, without using weights, of the difficult and long-standing problem of selecting

An Optimized Active Sampling Procedure for Aerobiological DNA Studies

Sensors, 2023
The Earth’s atmosphere plays a critical role in transporting and dispersing biological aerosols. Nevertheless, the amount of microbial biomass in suspension in the air is so low that it is extremely difficult to monitor the changes over time in these ...

Sea level, dinosaur diversity and sampling biases: investigating the ‘common cause’ hypothesis in the terrestrial realm [PDF]

, 2010
The fossil record is our primary window onto the diversification of ancient life, but there are widespread concerns that sampling biases may distort observed palaeodiversity counts.
