Most cosmologists don't dispute the primordial nature of the fluctuations
seen by COBE and other large-angle experiments.
To examine the smaller angularscale variations associated with the evolution of galaxy superclusters, clusters, or individual galaxies, researchers turn to larger antennas, which can resolve fluctuations
on a liner spatial scale.
recorded on the COBE and balloon maps are so faint that the charted hot and cold spots which vary a mere 30 millionths of a kelvin from the background -- represent only average variations over a large scale rather than particular hot and cold regions of the sky, Cheng explains.
By using the more predictable component, which displays less extreme fluctuations
than even the vacuum, researchers can substantially improve the sensitivity of their measurements (SN: 3/10/90, p.
But because the plants still fall within the same long time-scale eddy, the power they produce will have correlated fluctuations
at low frequencies, which generate the most power.
of the magnetic field will be monitored by a set of 16 optically-pumped alkali-vapor magnetometers (OPM), using the property that the oscillation frequency of an OPM is proportional to the modulus of the local magnetic field.
Much of the research on Holocene glacier and climate fluctuations
in western Canada has been done in the southern Canadian Rocky Mountains (see Luckman, 2000, for references).
in the solar wind affect our local space weather, predicting these is as challenging as predicting large changes in stock prices.
This results in a higher conveying efficiency and a significant reduction of pressure fluctuations
Real-time measurements on the spatial and temporal fluctuations
of single molecules in living cells, which are not possible using other methods, are a major goal of this initiative.
that influence auditors to revise their audit plans.
At the same time, strong fluctuations
occurred in the power-distribution grid in southern Sweden, damaging capacitors and power cables.
