The voice laboratory at the University of Navarre University Hospital has designed a novel and efficient protocol to evaluate and rehabilitate the voice of patients who have undergone laryngectomy. This involves a monitoring procedure based on patterns of phonatory flow. The study forms part of the PhD thesis by Dr Francisco Vázquez de la Iglesia. The title of the work is “Physiological Bases of the Pharyngoesophageal Segment. Characterisation of the erigmophonic voice as a function of its acoustic and aerodynamic parameters”.
Total laryngectomy is a surgical technique involving the radical extirpation of the larynx in patients suffering from advanced-stage cancer. According to Dr Vázquez, “these patients lose their capacity for oral communication, which greatly influences their quality of life. The most usual procedure for recovering the voice is the use of the esophagic voice. However, there is no diagnostic procedure enabling us to assess this quality of voice or that provides concrete rehabilitation measures that help to improve it”.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
