They compared this to activity in the dorsal attention network, which keeps us focused on one thing, and watched how the two fluctuated over time when people were asked to do a boring, repetitive task.
The unsteady nature of the spectra of the real-time velocities measured by two hot-wire sensors in a vortical flow region is investigated by using cross-correlation coefficient and retarded time of the two fluctuating velocities.
Given the problems associated with designing an appropriate control for a fluctuating temperature treatment and the SYNC/ASYNC experimental design used in the present study, as an alternative, researchers might adopt an experimental design with two fluctuating temperature treatments that vary only in peak temperature and fluctuate synchronously with a fluctuating UVBR irradiance regime.
While the two fluctuating temperature treatments would presumably lead to differences in growth rate and size, these effects could be accounted for using appropriate statistical analytical techniques (Freckleton, 2002; García-Berthou, 2001; Packard and Boardman, 1999) and thus the interaction between UVBR and temperature could still be considered.
Field-collected beetles were mated in the laboratory, and the offspring that hatched were equally subdivided into two fluctuating temperature regimes: stressful, with mean temperature of 17°C (13°C for 4 h, 20°C for 16 h), and more favourable, with mean temperature of 23°C (18°C for 4 h, 25°C for 16 h).
Both three and six genes are associated with rather major changes (Supplementary Figure 1a), and deletions with more than six genes fluctuate in frequency at low levels.
The populations of all six communities fluctuate in size due to families travelling between communities and regional centres for cultural, social, family and sporting reasons.
Indeed, inclusion of spt3Δ expression data did not significantly alter SPT3 rank across the representative FL experiments; three of the ranks increased while two widely fluctuated.
In France, the song peaked at number twelve, and spent nineteen weeks fluctuating within the French singles chart.
The men, though, could claim the title for the first time since 1924 after a day when the fortunes of the two teams fluctuated wildly.
No one knew whether any of this was actually going to happen and, as the fortunes of the two teams fluctuated through the final day, the parade was on, then off, then on, then off, then on again.
