If you are a budget-conscious traveler, there is a chance you've used a travel site aggregator like Orbitz to book your air transportation. Or, perhaps you shopped around on multiple aggregators, and made your final booking on an airline website. Did you ever wonder if you were presented with all airline options, or what kind of itineraries you could have received had you explored all airline sites one by one? Between aggregators and airlines, who ultimately has the upper hand?
Researchers have developed a suite of algorithms to improve the performance of cyber-physical systems - from autonomous vehicles to smart power grids - by balancing each component's need for data with how fast that data can be sent and received.
This scoring system for Covid-19 is simple, could be calculated in a few minutes, and incorporates the main possible data/findings of any patient.
Researchers led by PPPL have upgraded a key computer code for calculating forces acting on magnetically confined plasma in fusion energy experiments. The upgrade will help scientists further improve the design of breakfast-cruller-shaped facilities known as stellarators.
Most epidemics show infection curves with a typical S-shape. The COVID-19 outbreak, however, shows most infection curves exhibiting a linear growth after the first peak. Scientists at the Complexity Science Hub Vienna extend traditional models by describing the spread of disease as so-called cluster transmission. In this way, they are able to explain the typical linear shape of curves.
A mathematical discovery opens up new possibilities for architecture and design: For any desired curved surface a flat grid of straight bars can be calculated that can be folded out to the desired curved structure. The result is a stable form that can even carry loads.
Integrating first-of-its-kind washable hydrogel electrodes with a pulse sensor, researchers from the University of Massachusetts Amherst have developed smart eyewear to track eye movement and cardiac data for physiological and psychological studies. The eyewear -- known as Chesma and presented August 20 in the journal Matter--provides accurate measurements in an everyday environment without compromising users' comfort.
For nearly 50 years, a statistical omission tantamount to data falsification sat undiscovered in a critical study at the heart of regulating one of the most controversial and widely used pesticides in America -- chlorpyrifos.
Many quantum materials have been nearly impossible to simulate mathematically because the computing time required is too long. Now a joint research group at Freie Universität Berlin and the Helmholtz-Zentrum Berlin (HZB, Germany) has demonstrated a way to considerably reduce the computing time. This could accelerate the development of materials for energy-efficient IT technologies of the future.
A world-first study examines the scales of management of the Great Barrier Reef. The findings have the potential to help sustain other ecosystems across the world. The study provides a new approach for diagnosing social-ecological scale mismatches and responding to them.
