TL;DR: TT on DSA correlates with cerebral AVM flow measured using QMRA and with AVM angioarchitecture and hemorrhagic presentation and may be an indicator of important AVM characteristics associated with outflow resistance and increased rupture risk, such as venous stenosis.

Ahmed Mohamed,Shreya Ghosh,Marcos Araque,Debopam Datta,Mojgan Mazouchi,Vaidehi Rane,Mitra Dutta,Michael A. Stroscio +7 more
TL;DR: In this paper, the quantization of the acoustic modes in nanomechanical systems with coupled acoustic and electromagnetic modes in piezoelectric structures is studied, where the relationship between acoustic modes and the electromagnetic modes can be examined in the limit where the acoustic mode is a single acoustic phonon.

Noise processes in nanomechanical resonators
Andrew Cleland,Michael L. Roukes +1 more
TL;DR: In this article, a self-contained formalism for treating thermomechanical noise, Nyquist-Johnson noise, and adsorption-desorption noise was developed to estimate the impact that these noise processes will have on the noise of a model nanoscale resonator.

Systems with Small Dissipation
TL;DR: In this paper, a virtual encyclopedia of theoretical formulas, experimental techniques, and practical lore derived from twenty-five years of experience is provided for the experimenter who wishes to construct near-perfect instrumentation, providing information on the role of phonon-phonon scattering as a fundamental source of dissipation.
