A magnetic-modulator-type current-dividing highly stable DC current transformer for large currents

IEEE Transactions on Instrumentation and Measurement, 1991
A highly stable current-dividing DC current transformer system using a second-harmonic type of magnetic modulator has been developed for a several-hundred-ampere highly regulated current source which is required for nuclear magnetic resonance measurements.

Stable current and voltage generation under process variation

2010 East-West Design & Test Symposium (EWDTS), 2010
A new stable current and voltage generation method is proposed. It allows obtaining stable operating point under process variation (PV) using well-known self-bias technique. Stability against various process corners is achieved using only one type of transistor as current (voltage) generating elements.

[Current Treatment of Stable Angina].

Praxis, 2015
Current therapy for stable angina includes surgical and percutaneous revascularization, which has been improved tremendously over the last decades. Smoking cessation and regular exercise are the cornerstone for prevention of further cerebrovascular events. Medical treatment includes treatment of cardiovascular risk factors and antithrombotic management,

Ivabradine: a Selective If Current Inhibitor in the Treatment of Stable Angina

Recent Patents on Cardiovascular Drug Discovery, 2006
The role of heart rate reduction in the management of myocardial ischemia and chronic stable angina is pivotal. However, broad use and appropriate dosing of commonly used rate-slowing drugs is limited by their poor tolerability. Ivabradine is a selective inhibitor of the If currents of the sinoatrial node cells.

A highly stable current or voltage source

Journal of Physics E: Scientific Instruments, 1972
A powerful iterative method of current stabilization is described which uses FETs in a chain. Zero temperature coefficient for small temperature excursions may be obtained at a certain current value characteristic of the individual transistor. By means of one or two fixed resistors very stable voltages of almost any value may be produced.

A portable and stable source of AC voltage, current and power

Proceedings of Conference on Precision Electromagnetic Measurements Digest, 1995
This paper describes a portable and stable source of AC voltage, current, and power. It was developed for use with the National Research Council of Canada (NRC) watt-voltampere (W-VA) Transfer Standard to provide high-accuracy on-site calibrations of standards maintained by Canadian electrical utilities in order to establish traceability of these ...

rf generation of stable high bootstrap current equilibria

Physical Review Letters, 1990
Self-consistent calculations of radio-frequency (rf), current-drive requirements are presented for tokamak, magnetohydrodynamics equilibria which have been tested for stability. These stable equilibria include ones which have been chosen to have a large fraction of the current generated by the neoclassical bootstrap effect, greatly reducing the ...

A stable low-current source for electrode polarisation

The Analyst, 1971
A constant-current source for the range nanoamperes to microamperes based upon the use of cheap operational amplifiers is described. It has proved satisfactory for use in differential electrolytic potentiometry and other bipotentiometric titrations.

Management of Stable Angina – Current Guidelines: A Critical Appraisal

Cardiovascular Drugs and Therapy, 2016
Guidelines provide recommendations to improve patient outcomes, but many of the recommendations made for treating patients with stable angina are opinion based rather than evidence based. Risk stratification to predict patients at an increased risk of myocardial infarction (MI) and sudden ischemic death, and selection of patients for possible ...

Minimising currents and the stable norm in codimension one

Comptes Rendus Mathematique, 2001
Let \(T\) be a closed current of dimension \((n-1)\) on the \(n\)-dimensional Riemannian manifold \(M\). Suppose that \(T\) is of locally finite mass.
