BCFs are often estimated from the octanol-water partition coefficient (KOW), especially when there is a lack of empirical data.

Due to the lack of empirical data of users' social relationships, we use well-known theoretical graph to represent the real network.

The choice of model is not entirely dependent on its numerical accuracy, however, as a lack of empirical data will often necessitate the use of a specific approach.
However, the long-term impacts of model-based development on maintenance effort and model complexity can hardly be investigated due to a lack of empirical data.
Despite the emerging evidence, there is lack of empirical data to actually characterize the burden and risk factors associated with road traffic fatalities, especially in low- and middle-income countries (Ameratunga et al. 2006; Peden and Toroyan 2005).

Due to the lack of empirical data about available contact or all encounters between a pair of SUs, to evaluate the uncertainty of contact ( {mathcal{C}}^{left i,bright)} ) along link l i, b), we assume that the minimum and maximum values of encounter duration for all encounters within contact ( {mathcal{C}}^{left i,bright)} ) is offered in Fig. 6.
Due to a lack of empirical data on CR for lionfish, we selected two values for CR, 5 and 15.
