Generalized Quantum Theory: Overview and Latest Developments

The main formal structures of Generalized Quantum Theory are summarized. Recent progress has sharpened some of the concepts, in particular the notion of an observable, the action of an observable on states (putting more emphasis on the role of proposition observables), and the concept of generalized entanglement. Furthermore, the active role of the observer in the structure of observables and the partitioning of systems is emphasized.Comment: 14 pages, update in reference

Glucose measurements by electrocatalytic sensor in the extracorporeal blood circulation of a sheep.

Glucose tolerance tests are monitored by means of an electrocatalytic glucose sensor in an animal experiment in extracorporeal circulation. The sensor is integrated via a vascular graft into an artery of the animal and is operated by the load program of an electronic device. The measurement principle of the electrocatalytic glucose sensor is based on the measurement of the electrode impedance at various potentials. Using the sensor, it is possible to carry out one continuous glucose determination on each day over a week. A calibration applicable to the entire measurement period is found by subsequent correlation of the measured values with the enzymatically determined glucose concentration. In this experiment the measuring error of the sensor is on average 20%
