Adding guarana and other popular substances, such as ginseng and taurine, to these types of drinks may generate "uncertain interactions", the researchers said.
In this paper, the problem of decentralized adaptive output-feedback stabilization is investigated for large-scale stochastic nonlinear systems with three types of uncertainties, including parametric uncertainties, nonlinear uncertain interactions and stochastic inverse dynamics.
First, all uncertainties influencing the performance of controlled outputs, which include internal unmodelled dynamics, external disturbances, and uncertain nonlinear interactions between subsystems, are refined into the total disturbance in the control channels of subsystems.
Finally, we conduct 122 groups of contrast tests based on uncertain protein interactions network data preprocessed by Todor et al. from MINT database.
The molecular mechanism that results in an aggregation of Aß with increasing age in the brain is still uncertain, but abnormal interactions with biometals (principally copper and zinc) may play a prominent role [15].
While the molecular mechanism of how this is achieved is uncertain, altered protein protein interactions (Wu et al., 2000; Vazquez et al., 2001; Sumitomo et al., 2004; Takahashi et al., 2006; van Diepen et al., 2009; Huang et al., 2012) as well as conformational changes (Odriozola et al., 2007; Rahdar et al., 2009) in PTEN have been suggested to be induced by phosphorylation.
Because the lipid overlay assay was performed at a single time point and at a single concentration of lipids, it is uncertain whether Syt lipid interactions have reached equilibrium and if the observed difference in the extent of binding of Syt to different anions has different affinities or different on or off rates.
However, details of the interaction remain uncertain as the exact topology of VDAC within the OMM is still unresolved (Colombini, 2012; Tomasello et al., 2013).
Health risks arise from the interaction of uncertain future climatic changes with complex ecological, physical, and socio-economic systems, which are simultaneously affected by numerous other changes, e.g. globalisation, demographic changes, and changes in land use, nutrition, health care quality.
