The top-down sequence of variables corresponds to the sequence that was indicated by the forward selection procedure.
Because visual search strategies like the ones requested for executing a lane change are mainly described as a top-down sequence of information processing steps [ 30], one needs to have a proper mental model of the sensorimotor sequences that must be executed.
In addition, the use of the instrument for top-down sequencing of proteins was explored since this instrument offers particular advantages to this approach.
The above discussion is limited to top-down sequencing of proteins lacking modified residues, but does our line of reasoning also hold true for EDD of posttranslationally modified proteins?
Electron transfer dissociation can then be used for top-down sequencing [138,139] of the intact protein to reveal site-specific information about the location of exposed side-chains.
The top-down sequence is province level, prefectural level, county level, township level and village level [ 13].
Furthermore, the crustacean hyperglycemia hormones (CHHs, 8.5 kDa) were isolated from the American lobster Homarus americanus and identified by integration of MS-based bottom-up and top-down sequencing approaches.
Peak 4 was very weak to be purified and analysed by top-down sequencing.
Unfortunately, successful application of ECD or ETD to top-down protein sequencing of disulfide-containing proteins requires collisional activation as a necessary step to improve the fragmentation efficiency.
In the case of sleeping position and SIDS, 'top-down' sequences of this kind have been documented across several European countries by McKee and others [ 1].
Interestingly, top down mass spectrometry analysis of FlaA from strain 17A did not produce any marker ions characteristic of glycan, although the mass of the protein is greater than could be predicted from its DNA sequence.
