A review is given of the development of the concept of an artificial tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly-glycolic acid, poly-lactic acid and poly-alpha-amino acids. As a non-degradable material microporous PTFE and bisphenol-A poly (carbonate) were in...

The 3D geometry of a hydrogen absorbing metal grain (Pd) is mimicked by membrane made the with identical properties, which sealed on one side semi-impermeable surface (Cu). loss through negligible, i.e., uptake measurement that bulk material (Sieverts measurement), but desorbs sufficient to be detected mass spectrometer. With this, two independent spatial and temporal kinetic properties are def...

In 1952, Hodgkin and Huxley and others generated a revolution in our concept of the axon membrane and how it propagates the action potential. In 1959, Bullock described another revolution, a “quiet revolution” in our concept of the functions performed by the remainder of the nerve cell. In this paper we have attempted to show a possible connection between these two revolutions. We have proposed...

The task of re-organizing the teaching materials to generate concept maps for MOOCs is significant to improve the experience of learning process, e.g. adaptive learning. This paper introduces a novel and tailored Semantic Concept Map (SCM), and we design a two-phase approach based on machine learning methods to generate it.
