Atom Lithography with Near-Resonant Light Masks: Quantum Optimization Analysis [PDF]

open access: yes, 2006
We study the optimal focusing of two-level atoms with a near resonant standing wave light, using both classical and quantum treatments of the problem.

Standing Waves Are Not Fibromuscular Dysplasia

open access: yesJACC: Cardiovascular Interventions, 2012
As physicians who care for a large number of patients with fibromuscular dysplasia (FMD) in our clinical practice, we read with interest the case of fibromuscular dysplasia of the left anterior descending coronary artery by Lluri et al. ([1][1]).

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Nanometer-scale spatial modulation of an inter-atomic interaction in a Bose-Einstein condensate

open access: yes, 2010
We demonstrate nanometer-scale spatial control of inter-atomic interactions in a Bose-Einstein condensate of ytterbium(Yb). A pulsed optical standing wave, tuned near an optical Feshbach resonance varies the s-wave scattering length continuously across ...

Two-particle scattering on the lattice: Phase shifts, spin-orbit coupling, and mixing angles [PDF]

open access: yes, 2007
We determine two-particle scattering phase shifts and mixing angles for quantum theories defined with lattice regularization. The method is suitable for any nonrelativistic effective theory of point particles on the lattice.

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Achilles tendon shear wave speed tracks the dynamic modulation of standing balance

open access: yesPhysiological Reports, 2019
Standing balance performance is often characterized by sway, as measured via fluctuations of the center of pressure (COP) under the feet. For example, COP metrics can effectively delineate changes in balance under altered sensory conditions. However, COP

Material Selection for Photothermal Driving of Micromachine Elements

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
The photothermal effect, which changes light into heat, can be used to generate driving force from thermal stress. Micro-cantilevers, the simplest micromachine element, are driven using a modulated laser diode and the frequency response characteristics ...

The Genesis of the Aortic Standing Wave [PDF]

open access: yesCirculation Research, 1953
On the basis of observations of arterial pulse forms in anesthetized dogs, a hypothesis is developed to account for the genesis of the aortic standing wave which is responsible for the dicrotic characteristics of pulses recorded from the abdominal-femoral system.
