Study shows one third of candidates are unlikely to benefit from ICD
Last year, about 170,000 people in North America had devices surgically implanted to stop potentially fatal arrhythmias. For many, these were life-saving, but for others they were unnecessary, uncomfortable, and sometimes dangerous. Now a new, noninvasive test may help determine which patients are most likely to benefit from the device, known as implantable cardiac defibrillator (ICD). A large, multicenter, NIH-sponsored study coordinated by Columbia University Medical Center researchers reported on the accuracy of the test was and was published in the latest issue of the Journal of the American College of Cardiology.
The test, known as the Microvolt T-wave Alternans (MTWA) test, measures the electrical activity in the heart while the patient is performing light exercise on a stationary bicycle or treadmill. It can detect an electrical signal that can identify a heart likely to generate a life-threatening rhythm disturbance, a signal too slight to be detected by the traditional electrocardiogram (ECG). The MWTA test will be most helpful for patients who are at risk but have not yet had a cardiac arrest. If an arrhythmia occurred in a patient who had an ICD, the device would deliver a pulse of electrical current through the heart in order to stop the potentially fatal arrhythmia.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
