The non-invasive blood pressure measurement is probably the most common medical measurement, due to its clinical significance and simplicity. The manual version of the technique was introduced in 1905 by Korotkoff and relies on a pressure-cuff, mercury manometer, and hearing of Korotkoff sounds. It is still preferred by most physicians over the available automatic devices for blood pressure measurement. In this paper, I review the physical and physiological basis of the manual and the automatic techniques for the non-invasive measurement of blood pressure. The scientific background of the different techniques helps us to assess their ability to provide accurate evaluation of arterial blood pressure and reliable detection of hypertension. © 2011 IEEE.

A new randomized algorithm is suggested, for extracting static-output-stabilizing-feedbacks, with approximately minimal-norm, for LTI systems. The algorithm has two similar stages, where in the first one the feasibility problem is solved, and in the second one the optimization problem is solved. The formulation is unified for the feasibility and for the optimization problems, as well as for continuous-time or discrete-time systems. The method is demonstrated by applying it to the hard (conjectured to be NP-hard) problem of the minimal-gain static-output-stabilizing-feedback, and to the hard (conjectured to be NP-hard) problem of regional pole-placement via static-output-feedback in non-convex or unconnected regions. A proof of convergence (in probability) that captures the two rounds of the algorithm is given, and complexity analysis is provided, under some mild assumptions. © 2015 Elsevier Ltd. Source

The axion modification of electrodynamics can be considered as produced by an irreducible part of the constitutive pseudotensor. In this paper, we study the modification of wave propagation produced by the second irreducible part, called the skewon. We introduce the notions of the skewon optic tensor and skewon optic covector. With these devices we prove that in a pseudo-Riemannian manifold endowed with an arbitrary skewon at least one solution of the dispersion relation is spacelike. This means that the skewon generates superluminal wave motion and is thus ruled out on the basis of special-relativistic principles. © 2013 American Physical Society. Source

Electrodynamics with a local and linear constitutive law is used as a framework for models violating Lorentz covariance. The constitutive tensor of such a construction is irreducibly decomposed into three independent pieces. The principal part is the anisotropic generalization of the standard electrodynamics. The two other parts, axion and skewon, represent nonclassical modifications of electrodynamics. We derive the expression for the photon propagator in the Minkowski spacetime endowed with a skewon field. For a relatively small (antisymmetric) skewon field, a modified Coulomb law is exhibited. © 2016 American Physical Society. Source
