Environmental Pollution, 2015
The threshold concentrations of pollutants are determined by extrapolating single-species effect data to community-level effects. This assumes the most sensitive endpoint of the life cycle of individuals and the species sensitivity distribution from single-species toxic effect tests, thus, ignoring the ecological interactions.

Sample size determination in clinical trials with multiple co‐primary binary endpoints
Statistics in Medicine, 2010AbstractClinical trials often employ two or more primary efficacy endpoints. One of the major problems in such trials is how to determine a sample size suitable for multiple co‐primary correlated endpoints. We provide fundamental formulae for the calculation of power and sample size in order to achieve statistical significance for all the multiple ...

Experimental Determination of Second Critical Endpoints in Fluid/Melt Systems
Mineralogical Magazine, 1998Fluid phases play an important role during many processes in the upper mantle and in the crust. They work as efficacious transport agents during mantle metasomatism and depress the solidus of silicates towards lower temperatures. Consequently, they have a prominent influence on the velocities of seismic wave propagation and on the rheological ...

An optimization algorithm for determining the endpoints of isolated utterances
ICASSP '81. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005This paper describes an optimization technique for locating the initial and final points of utterances. Acoustic parameters extracted from each signal segment are converted into a cost function versus time. An overall cost for the presence of a speech signal is introduced and is to be optimized with respect to the unknown initial and final points.

Measles virus neutralization assay with endpoint determination using RT-qPCR
Das Masernvirus ist ein humanpathogenes Paramyxovirus, welches vermutlich vom Rinderpestvirus der frühen Antike abstammt. Es ist hochkontagiös und löst bei Menschen die Masern aus, eine Erkrankung, welche mit schweren Komplikationen und Todesfällen einhergehen kann.openaire +2 more sources
