Zurich, Switzerland

ETH Zürich is an engineering, science, technology, mathematics and management university in the city of Zürich, Switzerland. Like its sister institution Swiss Federal Institute of Technology in Lausanne , it is an integral part of the Swiss Federal Institutes of Technology Domain that is directly subordinate to Switzerland's Federal Department of Economic Affairs, Education and Research.ETH Zürich is consistently rated among the top universities in the world. It is currently ranked 4th in Europe overall, and 3rd best university in the world in engineering, science and technology. Twenty-one Nobel Prizes have been awarded to students or professors of the Institute in the past, the most famous of which is Albert Einstein in 1921, and the most recent is Richard F. Heck in 2010. It is a founding member of the IDEA League and the International Alliance of Research Universities and a member of the CESAER network.The school was founded by the Swiss Federal Government in 1854 with the stated mission to educate engineers and scientists, serve as a national center of excellence in science and technology and provide a hub for interaction between the scientific community and industry.

A device (100) for a non-destructive measurement of mechanical properties of a test body (21) comprises a striker (4) having a tip (3). The striker is positioned above the test body and is configured that the tip impacts the test body (21) with a predetermined velocity (v0) causing a displacement (d), wherein at least one sensor (5) determines one of the physical values from the group of force acting on and acceleration of the striker. The device further comprises a control unit connected with the striker and configured to obtain the sensor signals over time (30) of the impact and the predetermined impact velocity and calculates a force-displacement diagram (35) based on the sensor signal and the knowledge of the predetermined impact velocity through Newtons second law and integrating the force profile while taking into account the normal modes of vibration of the strikers tip.


The invention relates to mammalian cells comprising at least one prokaryotic two-component signaling (TCS) pathway comprised of an activator protein A, a response regulator (RR) protein B activated by said protein A, such activation leading to an activated RR protein B, and an output gene C operably linked to a promoter. Transcription from said promoter is activated by activated RR protein B, and the expression of output gene C defines at least a first state (0, no transcription) and a second state (1, detectable transcription). The invention further relates to logic gates designed from such cells, and methods for integrating a plurality of output signals based on the cells and logic gates of the invention.

A method to measure the vibrational characteristics of an oscillating system (1) uses a control system (6,7a, 7b, 7c). The oscillating system comprises a resonator, at least one vibration exciter and at least one sensor. The resonator is excited by the vibration exciter, and the motion of the resonator is measured by the sensor. The control system uses the sensor to control the motion of the resonator by the vibration exciter. The motion of the resonator is a superposition of at least two harmonic motions, and the control system comprises at least two subcontrollers (7a, 7b, 7c). Each harmonic motion is controlled independently by one of the subcontrollers. The harmonic motions are controlled by the subcontrollers simultaneously. A corresponding device is also disclosed.
