In neurons showing eye-position modulations both in FIX and in at least one action epoch, post hoc tests (Bonferroni-corrected t-test, P < 0.05) were used to determine specific differences among the gaze directions, therefore obtaining the pattern of modulation for each epoch (i.e. a ranking of gaze directions based on the recorded neural mean activities).
The key problem of dynamic single epoch GPS positioning is the rapid decomposition of ambiguity.
A sequential version of the GINS software has been implemented to achieve single epoch GPS positioning.
Finally, for hourly data, ambiguity resolution can significantly improve the accuracy of epoch-wise position estimates from 13.7, 7.1 and 11.4 cm to 0.8, 0.9 and 2.5 cm for the East, North and Up components, respectively, but a few tens of minutes is required to achieve the first ambiguity-fixed solution.
In this approach, we keep all relevant global geodetic parameters fixed and estimate the satellite clock and antenna phase center positions epoch-by-epoch using 30-second observation and clock data from a global multi-GNSS ground station network.
To this purpose, we defined an index of modulation Im that was calculated separately for each of the two tasks, as follows: where f nij is the mean firing frequency of cell n during epoch i for tested position j.
His 1864 paper On the Physical Cause of the Changes of Climate during Glacial Epochs led to a position in the Edinburgh office of the Geological Survey of Scotland, as keeper of maps and correspondence, where Sir Archibald Geikie, encouraged his research.
Furthermore, the performance assessment of single-epoch multi-baseline positioning was analyzed.
One way to test for slow changes would be to divide the spikes according into several different groups depending on their position in the epoch.
We then verified whether the effect of eye position on action epoch(s) was consistent with that on fixation-related activity by comparing the corresponding patterns of modulation.
