Different pretreatment methods exist, each with unique action mechanisms, such as removing hemicelluloses and/or lignin, reducing the cellulose crystallinity, and increasing the biomass surface area.
As noted in [20], other limitations of the likelihood methods exist, in particular with respect to the incorporation of uncertainties about calibration points into an analysis; these limitations are however naturally dealt within a Bayesian framework [20].
For example, a variety of analytical methods exist for dealing with selection bias 60 64 and surveillance bias.
Very few physical synthesis methods exist that are compatible with transparent oxide substrates due to the high synthesis temperatures that are 900 1,200°C [10].
While methods exist for QTL mapping with function-valued phenotypes, they are generally computationally intensive and focus on single-QTL models.
Numerous methods exist for peptide modification with respect to sequence, backbone or side chains, also incorporating non-proteinogenic amino acids (Gante 1994).
For these models, powerful methods exist for detecting association with rare genetic variation [ Asimit et al., 2012; Neale et al., 2011; Wu et al., 2011.
Other methods exist that combine molecular data with morphological data to reveal additional phylogenetic signals, but it is then not clear how to reconstruct the tree using generally accepted models of evolution.
