Miniaturizing the iron oxide particles to certain sizes in which each particle consists of a single magnetic domain with thermal energy high enough to overcome the energy barrier of magnetic flipping could generate local interactions with water protons that can induce proton
dephasing and shorten transverse T2 relaxation.
To assess stenosis, an SSFP gradient echo sequence will demonstrate the
dephasing jet through the site of obstruction.
Refocused pulses, usually 180[degrees], correct many sources of
dephasing, making FSE imaging effective for minimising susceptibility artifact.
A virtual-reality program is being developed to misalign sound from video, a technique called
dephasing, in ways that mimic the experience of disordered thinking in psychiatric illness.
SPION is known as a negative contrast agent, but USPION is a positive contrast agent because of its very short T2 relaxation time, basic T1-weighted acquisition, and
dephasing gradient effect on slice axis.
Here we report an experiment which shows for the first time that quantum coherence in a large ensemble of nuclear spins can be naturally preserved under exposure to strong
dephasing noise at room temperature, without external control, and for timescales as long as a second and beyond.
2009) Universality of bias- and temperature-induced
dephasing in ballistic electronic interferometers.
It is NOT quantum decoherence; in fact,
dephasing rather than decoherence is in any case how quantum states seem to occur and unravel in nature, with surrounding "noise" actually helping the coherence.
Main interests in neutral modes in the QHE regime are: (a) Their direct association with the nature of the wavefunction of the quantum state; (b) Being excited when a charge mode is being partitioned (say, by a quantum point contact), they may play a prime role in
dephasing interference of quasi-particles due to the energy they rob (in the partitioning process).
As Manning describes it, "the milieu is hyperrelational, every act calling forth a
dephasing, a transduction, a welling of an environmentality that constitutively challenges the oneness of self separated from the milieu of interaction, its skin intact" (2013, 9).
The force of inhomogeneous field around the vessel is the susceptibility difference between inside and outside vessel, which is the static
dephasing regime (SDR) effect.
When the field changes speedily with position, there is significant
dephasing of the signal, resulting in signal loss.
