Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

Mapping of Euclidean resonance on static resonant tunneling [PDF]

open access: yesarXiv, 2004
Quantum tunneling through an almost classical potential barrier can be strongly enhanced by a nonstationary field so that the penetration through the barrier becomes not exponentially small. This constitutes an extremely unusual phenomenon of quantum physics called Euclidean resonance.

Spectroscopy of Three-Particle Entanglement in a Macroscopic Superconducting Circuit

open access: yes, 2005
We study the quantum mechanical behavior of a macroscopic, three-body, superconducting circuit. Microwave spectroscopy on our system, a resonator coupling two large Josephson junctions, produced complex energy spectra well explained by quantum theory ...

Soft lithography replica molding of critically coupled polymer microring resonators [PDF]

open access: yes, 2004
We use soft lithography replica molding to fabricate unclad polystyrene (PS) and clad SU-8 microring resonator filters. The PS resonator has an intrinsic quality factor of 1.0/spl times/10/sup 4/ at /spl lambda/=1.55 /spl mu/m, while that of the SU-8 ...

An Integrable Model for the Dynamics of Planetary Mean Motion Resonances [PDF]

open access: yes, 2019
I consider the dynamics of mean motion resonances between pairs of co-planar planets and derive a new integrable Hamiltonian model for planets' resonant motion. The new model generalizes previously-derived integrable Hamiltonians for first-order resonances to treat higher-order resonances by exploiting a surprising near-symmetry of the full, non ...

Cavity piezooptomechanics: piezoelectrically excited, optically transduced optomechanical resonators

open access: yes, 2013
We present a monolithic integrated aluminum nitride (AlN) optomechanical resonator in which the mechanical motion is actuated by piezoelectric force and the displacement is transduced by a high-Q optical cavity.

The resonance strategy

open access: yesComputers & Mathematics with Applications, 1995
AbstractEspecially in mathematics and in logic, lemmas (basic truths) play a key role for proving theorems. In ring theory, for example, a useful lemma asserts that, for all elements x, the product in either order of 0 and x is 0; in two-valued sentential (or propositional) calculus, a useful lemma asserts that, for all x, x implies x.
