Net current measurements and secondary electron emission characteristics of the Voyager plasma science experiment and their impact on data interpretation [PDF]

The Voyager Plasma Science (PLS) instrument is capable of returning integral (DC) current measurements, similar in some respects to measurements made with a Langmuir probe or a retarding potential analyzer, although there are significant differences. The

Bank Value and Financial Fragility [PDF]

We propose a valuation model for a bank which faces a bankruptcy risk. Banks are identified with a possibly infinite random sequence of net benefits. A bank is solvent as long as its benefits remain non-negative.
