Pressbox (Press Release) - ?3A ?. Here, the position of the concentration front in space is evaluated at the concentration equal to the complex threshold C?=C?T=0.3. Within one period of the oscillatory flow, the profiles of the front change significantly ( Fig.?3B ?). The averaged propagation velocity is then found as the slope u?=dx?/dt? of the linear fit in the stable periodic regime ( Fig.?3A). Dependences of the average propagation velocity on the period of the oscillatory flow are plotted in Fig.?4. The characteristics are typically nonlinear with lower and upper asymptotes (dashed lines ?). Several inflection points as well as a distinct velocity maximum at T?��3 are identified for two of the three considered parameter sets. The common feature of Crizotinib supplier all these dependences is that larger periods of the oscillatory flow accelerate the autocrine communication more significantly than the shorter ones. The velocity increase C-646 amounts to several tens of percent for parameter Sets 1 and 2 and>100% for parameter Set 3. As we will show in the discussion, the character of these dependences results from different timescales of the reaction and transport processes at the cellular layer. In general, the quantitative character of the calculated frequency characteristics depends on the choice of the sharpness parameter ��? in Eq. 11. To document this effect, we selected a periodic regime corresponding to the maximum in Fig.?4A ? and studied the effect of the parameter ��? click here on the propagation velocity (see the Supporting Material). The propagation velocity attains an asymptotic value for ��???<0.02, and this value corresponds to the Heaviside dependence of the protease activity on the complex concentration. An increase of ��? above 0.02 leads to an increase of the propagation velocity. However, the relative difference between the propagation velocities in the asymptotic regime and for ��?=0.1 does not exceed 5%, i.e., our results are not significantly affected in a wide range of the sharpness parameter. All amplitude characteristics showing u? versus PeA plotted in Fig.?5 are monotonous and increasing in the studied range. In certain ranges of periods of the flow oscillations T?, the velocity increase exceeds 100%. For T?��0, we find u? to be the same as the velocity of the signal propagation in the absence of the convective transport. The amplitude characteristics are plotted only for Set 1; qualitatively identical behavior is found for the other sets. From the above results, we can conclude that the oscillatory convection in the extracellular space can, under certain conditions, lead to a significant acceleration of the signal transmission when compared to the no-convection system. In the following, we explain the observed findings and compare them qualitatively with available experimental results. We will now focus on the lower asymptote of the frequency/period characteristics shown in Fig.?4.
