It is clear that this fails to capture the temporal behaviour of the fluxes and additional consideration of parametric models is compulsory to fully explain the fluxes; further, this approach is susceptible to noise that is present in experimentally measured metabolite data.
However, a different conclusion was subsequently drawn by García- Hernández et al. (2012a) who subtracted the contribution of C70 to the observed 7.0 μm flux and found that the UV- excitation model cannot explain the C60 flux ratios for a larger sample of PNs.
The results reasonably explain the magnetic flux maps, such as those imaged in Fig. 4h,i, in which the ferromagnetic spin order persists in the narrow APB region.
We caution that differences in sampling grid/density (that was significantly higher in the present surveys, as can be also observed in the number of points of Table 2) can partially explain the CO2 flux diversity between the two campaigns (Viveiros et al. 2010).
Similarly, the reduced demand for fatty acid and TG building blocks, respectively, could explain the reduced flux of acetyl-CoA and PEP.
The acetyl-CoA output for fatty-acid synthesis was also increased after resistin treatment, which would explain the higher flux towards the TCA cycle.
CoreReg is fundamentally different, as it aims to explain the observed flux redirections as the consequence of a bound contraction of a small set of reactions (the core set).
Considered reactions explain the major fluxes of carbon and nitrogen, namely glycolysis, glutaminolysis, TCA cycle, pentose-phosphate pathway, recombinant product synthesis and biosynthesis of cellular components (nucleotides, carbohydrates, lipids and proteins).
Using simultaneous satellite observations of electrons at two altitudes in the cusp, Lin et al. (1986) showed that some parallel potential drop is needed to explain the enhanced energy flux observed in the lower-altitude electrons, although we do not know whether their enhanced energy flux events are related to cusp moving auroral structures.
