Changes in the Quality and Nontargeted Metabolites of Salt-Fermented Shrimp (Saeu-jeot) Based on Fermentation Time

open access: yesFermentation, 2023
Saeu-jeot is a widely consumed variety of jeotgal, a South Korean salt-fermented food. However, there is a lack of existing studies conducting nontargeted metabolomic analyses of saeu-jeot during fermentation.

Efficient spin control in high-quality-factor planar micro-cavities [PDF]

open access: yes, 2012
A semiconductor microcavity embedding donor impurities and excited by a laser field is modelled. By including general decay and dephasing processes, and in particular cavity photon leakage, detailed simulations show that control over the spin dynamics is

Quality factor due to roughness scattering of shear horizontal surface acoustic waves in nanoresonators [PDF]

open access: yes, 2008
In this work we study the quality factor associated with dissipation due to scattering of shear horizontal surface acoustic waves by random self-affine roughness. It is shown the quality factor is strongly influenced by both the surface roughness exponent H, and the roughness amplitude w to lateral correlation length X ratio.

Spin Waves in Quantum Gases --- The Quality Factor of the Identical Spin Rotation Effect [PDF]

open access: yesPhys. Scr. 93 094002 (2018), 2018
Our recent experimental work on electron spin waves in atomic hydrogen gas has prompted a revisit of the theory of the Identical Spin Rotation Effect (ISRE). A key characteristic determining the properties of the spin waves is the quality factor of ISRE. Unfortunately, calculating this quality factor takes some toil.

Mechanical quality factor of a sapphire fiber at cryogenic temperatures [PDF]

open access: yes, 2000
A mechanical quality factor of $1.1 \times 10^{7}$ was obtained for the 199 Hz bending vibrational mode in a monocrystalline sapphire fiber at 6 K. Consequently, we confirm that pendulum thermal noise of cryogenic mirrors used for gravitational wave ...
