Value of acoustic rhinometry for measuring nasal valve area.
TL;DR: To assess the validity of acoustic rhinometry for measuring nasal valve area in human subjects, a large number of subjects were recruited for studies on sneezing and wheezing patterns.
Acoustic rhinometry in humans: accuracy of nasal passage area estimates, and ability to quantify paranasal sinus volume and ostium size
TL;DR: The results suggest that AR measurements of the healthy adult nasal cavity are reasonably accurate to the level of the paranasal sinus ostia and beyond this point, AR overestimates cross-sectional area and provides no quantitative data for sinus volume or ostium size.

Acoustic rhinometry in healthy humans: accuracy of area estimates and ability to quantify certain anatomic structures in the nasal cavity.
TL;DR: The local minima on the AR area-distance curve beyond the nasal valve are caused by acoustic resonances in the nasal cavity, and do not correspond to any anatomic structure.
Well-width dependence of the in-plane effective mass and quantum lifetime of electrons in multiple quantum wells
TL;DR: In this article, the electronic properties of modulation-doped multiple quantum wells (MWQ) with well width in the range between 51 and 145? have been investigated by using the Shubnikov - de Haas (SdH) oscillations technique.

Warm-electron power loss in GaAs/Ga1-xAlxAs multiple quantum wells: Well-width dependence.
TL;DR: With decreasing confinement length, acoustic phonons become less efficient in cooling electrons than those predicted by the theoretical models, and it is argued that this discrepancy may be associated with the overestimated piezoelectric component and with the simplifying assumptions made in the theoretical calculations.
