The signals recorded by a microphone array, with sensors denoted with indices in an acoustic environment where sound sources are present, can be modeled as a finite impulse response convolutive mixture, written as (1).
"Since multiple pathways are involved in [the] photocarcinogenic response, a mixture of several phytochemicals working through different cell signaling pathways or other mechanisms could be an effective strategy".
Powder physical and chemical properties, powder mixtures, response of powder mixtures to the pharmaceutical processes (mixing, roll compaction, milling, tableting, coating, etc)., and the processes themselves can add to the complexity within the whole system.
Cbh1 and CelD enzyme mixtures on crystalline cellulosic substrates show a strong combinatorial effort response for mixtures where Cbh1 is present in 2 1 or 4 1 molar excess.
This is a very interesting result because it illustrates clearly that the toxic response to mixtures may be different from the toxic response of the individual components of the mixture.
The bees' response to mixtures composed of only the key odorants was as good as to the original mixtures of 14 odorants.
Based on these concentration-response data, mixture effects were predicted by applying the model of concentration addition.
The previous studies have compared the recorded transcriptomic response to mixtures against responses to individual stressors, but have not formally evaluated interactive effects between the stressors.
Statistically significant deviations of biomarkers responses from mixture toxicity reference models were analyzed using the MIXTOX spreadsheet model developed by [ 7].
This approach has been used to evaluate the biological response to mixtures of polychlorinated biphenyls (PCBs) before and after remediation by reductive dechlorination.
If responses to mixture components would add up linearly ("linear interpolation"), many naturally occurring odors with tens or hundreds of components might quickly lead to saturated receptor cell output, thus reducing the coding capacity of the system.
