Sentences with phrase «frequency shifts»

The researchers found that atom collisions were reduced such that their contribution to frequency shifts in the clock was much less than in previous experiments.

We tried to match up the allele frequency shifts in this experiment with the genome - level differentiation that we observed in our genome - resequencing populations.

By precisely measuring the orbital movements of MESSENGER using the subtle Doppler frequency shifts of its radio signal, geodesist David Smith of the Massachusetts Institute of Technology in Cambridge and 16 colleagues measured how the pull of gravity varies across Mercury, as the team reports online today in Science.

«In this work, both theoretically and experimentally, we demonstrated that even though the electron is rotating this way and the light is rotating (the other) way, they still strongly interact with each other, which leads to a finite frequency shift known as the Bloch - Siegert shift,» Kono said.

The more harmful substances, the greater the so - called centre frequency shift,» says Tobias Erlöv, who is currently continuing his research at the Department of Biomedical Engineering.

As a demonstration, the JILA team created a series of images to map small frequency shifts, or fractions of atoms in the excited state, across different regions of the lattice.

In all Brillouin sensors, the strain and temperature dependence of the Brillouin frequency shift (BFS) is exploited to derive strain and temperature.

Kono and his colleagues created the resonance frequency shift in a two - level electron system induced by coupling with an electromagnetic field inside a cavity even when the electrons and field are rotating in opposite directions — a truly surprising effect that occurs only in a regime where light and matter are mixed together to an extreme degree.

Allele frequency shifts for FMR1 and MSN from O. c. algirus to O. c. cuniculus are abrupt and few introgressed alleles are found in the other subspecies territory.

By using lasers, the kinetic energy of the ions can be cooled to millikelvin temperatures, thereby suppressing Doppler frequency shifts.

This vacuum - matter hybridization had been expected to lead to a finite frequency shift, a vacuum Bloch - Siegert shift, in optical spectra for circularly polarized light counter-rotating with the electrons.

This nonlinear approach — focusing on frequency shifts relative to signal strength rather than the frequency shifts alone — is especially useful because it is not affected by slight variations in size of the capacitors.

Mixing light from these dual frequency combs together creates a «beat» frequency shifted down to the radio band, low enough to be measured.

For a Fermi quantum gas under this clock's operating conditions, quantum mechanics favors a configuration where each individual lattice site is occupied by only one atom, which prevents the frequency shifts induced by atomic interactions in the 1 - D version of the clock.

In prior data, from 1995 to 2007, the frequency shifts in the oscillations had matched up well with the sunspot counts.

Molecules in the Universe emit radio waves with their characteristic frequency, and if the molecules are moving, the frequency shifts slightly due to the effect.

I'd love to know more about the details: is this case like a perfectly elastic collision, or are there subtler effects on the radiation's characteristics (polarization, phase shifts, frequency shifts?)

Hank, it's not that the frequency shifts to lower values, but that the band narrows.

And shots of galaxies, nebulas, and dust clouds take on startling hues thanks to frequency shifting.
