In recent years there has been a growing interest in the study of sparse representation of signals. Using an overcomplete dictionary that contains prototype signal-atoms, signals are described by sparse linear combinations of these atoms. Applications that use sparse representation are many and include compression, regularization in inverse problems,(More)
A theoretical method is derived for computation of the interactin of pressure and a weak anesthetic such as nitrogen or other narcotic gases in a two-dimensional material so as to prevent signs and symptoms of the high pressure nervous syndrome. A ratio of one part nitogen to 9 parts helium (pressure) is derived, which is in excellent agreement with(More)
This article presents and analyses several cases in which the use of the cut-off effect is useful. It starts from the fact that an anesthetic effect of homologous agents is always expressible as a function of their chain lengths and that the cut-off point is a point at which the function vanishes. We then investigate four categories of results: (i) whole(More)

The Meyer-Overton rule is used extensively in the analysis of general anesthesia, but there is no satisfactory explanation of its origins. In this article we explore its physical content and show that it is not possible to explain this rule by using anesthetic potencies alone: we must consider also the perturbations at anesthetic sites. We then show that,(More)
