Using spiking studies Can be done at the laboratory and can be done with the real samples, thereby exactly matching the matrix. The main problem in bias determination by spiking is dispersing the analyte in the sample in the same way as the native analyte in the sample.

Spiking solutions
· If you make your spiking solution 10x more concentrated, then you have 10ng/ul and you can spike 10ul into the 500ul of matrix which gives you 100ng/510ul which would be 196ng/1ml. If you make your spiking solution 100x more concentrated, then you have 100ng/ul and you can spike 1ul into the 500ul of matrix which gives you 100ng/501ul which would be 199.6ng/1ml.

· It is often medically necessary to provide results for specimens with concentrations above the analytical measuring interval of an in vitro diagnostic measurement procedure. This guideline helps manufacturers and laboratory scientists with establishing, validating, or verifying a dilution scheme that will provide an extended measuring interval for such specimens.

Spiked Substances
Spiking Side Effects Across a majority of all of the symptoms studied, women experienced spiking side effects more heavily than men. Research suggests basic biology and chemistry may account for why women may feel the effects of drugs and alcohol more.
Solvent Miscibility Table
Miscibility defines how substances combine (or mix) to form a homogenous solution without precipitates. Miscibility most often refers to liquids but can also apply to gas and solid phases. Research concerning miscibility often involves the materials science chemistry domain where additional strategies to predict substance interactions could accelerate discoveries.

Spiking activity in the human hippocampus prior to …
Brain activity in the medial temporal lobe associated with the onset of a study item is thought to influence encoding and, therefore, subsequent memory for that item. However, our study found that spiking activity in the hippocampus prior to the onset of the to-be-studied item predicted both activity during encoding and subsequent memory. Thus, when the hippocampus is in a “ready-to-encode

A brainy idea! The collective spiking behavior of a 1D chain of linearly coupled neurons was investigated. As shown in the Figure, the coefficient of variance of the spike train reaches a clear min Chemistry—A European Journal European Journal of Inorganic
BURSTING, SPIKING, CHAOS, FRACTALS, AND …
With the bifurcating diagrams, we explain how spiking can be transformed to bursting via a complex type of dynamic structure when the key parameter in the model varies. Understanding how this parameter would affect the bifurcation structure is important in predicting …
Interference indices
The guidelines below indicate how lipemia, based on the lipemia index, may affect results on our current chemistry analyzer. These guidelines are derived from manufacturer’s recommendations and are based on data from spiking human samples with Intralipid®.
