this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

We propose two new classes of Bayesian measure to investigate conflict among data sets from multiple studies. The first (“concentration ratio”) is used quantify the amount information provided by a single set through comparison prior and its posterior distribution, or according their corresponding distributions. second class (“dissonance”) quantifies extent contradiction between sets. Both are ...

Many animal species rely on chemical signals to extract ecologically important information from the environment. Yet in natural conditions chemical signals will frequently undergo concentration changes that produce differences in both level and pattern of activation of olfactory receptor neurons. Thus, a central problem in olfactory processing is how the system is able to recognize the same sti...
