Measurements of these rates using time-resolved FRET revealed that DNA within the nucleosome remains fully wrapped for only 250 ms before it is unwrapped for 10-50 ms and then rapidly rewrapped.

Measurements carried out in Ulan Bator have shown that PM is by far the most serious component of the air pollution problem.

Measurements are usually made at a peak to minimize errors produced by errors in wavelength in the instrument, that is errors due to having a different extinction coefficient than assumed.

Measurements showed that, unlike in former times, the wave energy of the sea is not any more consumed off the beach, today it carries its destructive effects on to the beaches proper.

Measurements of Fomalhaut's rotation indicate that the disk is located in the star's equatorial plane, as expected from theories of star and planet formation.

Measurements from the Spectral Irradiance Monitor on NASA's Solar Radiation and Climate Experiment show that solar UV output is more variable over the course of the solar cycle than scientists had previously thought, resulting in, for example, colder winters in the US and southern Europe and warmer winters in Canada and northern Europe during solar minima.

Measurements in the late 1960s showed that the orbital velocity of stars in spiral galaxies with respect to their distance from the galactic center is indeed higher than expected from Newtonian dynamics but still cannot explain the stability of the spiral structure.

When the temperature profile is adiabatic, the wind speed should vary logarithmically with height, Measurements over open terrain in 1961 showed good agreement with the logarithmic fit up to 100 m or so, with near constant average wind speed up through 1000 m .< ref name = Thuillier >

Measurements of one particle will be correlated with measurements on the other particle, but this is only known after the experiment is performed and notes are compared, therefore there is no way to actually send information faster than the speed of light.

Measurements of motorist speed throughout time have found many roadways where compliance with speed laws is very low, making many motorists liable to be pulled over at the discretion of law enforcement.

Measurements of actual programs suggest that an 8 or 10 bit offset is large enough for some 90 % of conditional jumps.
