We propose a new integral equation formulation to characterize and compute transmission eigenvalues in electromagnetic scattering. As opposed to the approach that was recently developed by Cakoni, Haddar and Meng (2015) which relies on a two‐by‐two system of boundary integral equations, our analysis is based on only one integral equation in terms of the electric‐to‐magnetic boundary trace operator that results in a simplification of the theory and in a considerable reduction of computational costs. We establish Fredholm properties of the integral operators and their analytic dependence on the wave number. Further, we use the numerical algorithm for analytic nonlinear eigenvalue problems that was recently proposed by Beyn (2012) for the numerical computation of the transmission eigenvalues via this new integral equation.

The usefulness of ice application in the treatment of epistaxis as a first aid method is not generally accepted, but is widespread. In order to evaluate the effect of cold application on the blood vessels of the nasal mucosa, their blood flow and blood content were investigated on 56 healthy volunteers before and after exposure to cold in the neck area. Nasal mucosal microcirculatory blood flow was measured directly by non-invasive laser Doppler flowmetry in Kiesselbach's area. Changes in the nasal mucosal blood content were estimated using a conventional computer-aided rhinomanometer by measuring alterations in nasal airflow. After ice application in the neck area, no statistically significant effects on the blood vessels of the nasal mucosa were seen. These results do not support the usefulness of this manoeuvre in the treatment of epistaxis. [ABSTRACT FROM AUTHOR]
