Accuracy of electron counting using a 7‐junction electron pump
We have operated a 7‐junction electron pump as an electron counter with an error per pumped electron of 15 parts in 109 and an average hold time of 600 s. The accuracy and hold time are sufficient toExpand

Theory for a dissipative droplet soliton excited by a spin torque nanocontact
A distinct type of solitary wave is predicted to form in spin torque oscillators when the free layer has a sufficiently large perpendicular anisotropy. In this structure, which is a dissipativeExpand

Value of regional wall motion abnormality in the emergency room diagnosis of acute myocardial infarction. A prospective study using two-dimensional echocardiography.
Because regional wall motion abnormality (RWMA) is usually noted during ischemia, we hypothesized that the presence of this finding with two-dimensional echocardiography would be superior toExpand

The behavior of sonicated albumin microbubbles within the microcirculation: a basis for their use during myocardial contrast echocardiography.
The purpose of this study was to determine whether the behavior of sonicated albumin microbubbles accurately mimics red blood cell flow in the microcirculation and is thus consistent with their useExpand

Nonequilibrium quasiparticles and 2e periodicity in single-Cooper-pair transistors.
We have fabricated single-Cooper-pair transistors in which the spatial profile of the superconducting gap energy was controlled by oxygen doping. The profile dramatically affects the switchingExpand

Time domain measurement of phase noise in a spin torque oscillator
We measure oscillator phase from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of the phase noise varies withExpand

Determination of capillary tube hematocrit during arteriolar microperfusion.
Intracapillary hematocrit is known to be substantially lower than arterial hematocrit. We hypothesized that capillary hematocrit might be influenced by interactions between plasma macromolecules andExpand

Value of two-dimensional echocardiography for determining the basis of hemodynamic compromise in critically ill patients: a prospective study.
We postulated that because the first step in the management of critically ill patients with hypotension, pulmonary edema, or both is to determine whether the cause is cardiac or noncardiac, directExpand

Sonicated echocardiographic contrast agents: reproducibility studies.
This article describes the production, analysis, and reproducibility of forming microbubbles for contrast ultrasound imaging. The sonication method used to generate microbubbles was tested by fourExpand
