EMST model

As discussed in Subramaniam and Pope (1998), the EMST model does not satisfy the independence and linearity properties proposed by Pope (1983). 

The support of a PDF is the sub-set of composition space whereon the PDF is non-zero. Thus, a one-dimensional support is a curve in two- (or higher) dimensional space. The intermittency feature in the EMST model will cause the support to thicken around the stoichiometric point, so that it will be locally two-dimensional. 

Likewise, if (F) (0) lies well below the reaction zone, the IEM model will collapse all points outside the reaction zone towards the mean values without passing through the reaction zone, i.e., the flame will be quenched even when the local reaction rate is infinite.66 Such unphysical behavior is avoided with the EMST model (Subramaniam and Pope 1999). 

Although (t ) is not explicitly input into the EMST model, a form is implied by the interaction matrix, which is affected by chemistry through the PDF shape. 

Structure-activity studies suggested pheromones were detected by receptor proteins [37, 38], and chemicals that disrupt protein structure had been used to uncouple odour response pathways [39, 40], In 1974, Karl-Emst Kaissling [41] proposed a model for pheromone detection in silk moths in which pheromone molecules were transported to neuronal receptor proteins via pore-tubules [42, 43] and were subsequently inactivated by some rapid non-enzymatic process.
