Earthquakes reveal deep secrets beneath East Asia | PHYS.org

Earthquakes reveal deep secrets beneath East Asia | PHYS.org | Sciences & Technology | Scoop.it

A new work based on 3-D supercomputer simulations of earthquake data has found hidden rock structures deep under East Asia. Researchers from China, Canada, and the U.S. worked together to publish their results in March 2015 in the American Geophysical Union Journal of Geophysical Research, Solid Earth.

 

The scientists used seismic data from 227 East Asia earthquakes during 2007-2011, which they used to image depths to about 900 kilometers, or about 560 miles below ground.

 

Notable structures include a high velocity colossus beneath the Tibetan plateau, and a deep mantle upwelling beneath the Hangai Dome in Mongolia. The researchers say their line of work could potentially help find hidden hydrocarbon resources, and more broadly it could help explore the Earth under East Asia and the rest of the world.

 

"With the help of supercomputing, it becomes possible to render crystal-clear images of Earth's complex interior," principal investigator and lead author Min Chen said of the study. Chen is a postdoctoral research associate in the department of Earth Sciences at Rice University.

 

Chen and her colleagues ran simulations on the Stampede and Lonestar4 supercomputers of the Texas Advanced Computing Center through an allocation by XSEDE, the eXtreme Science and Engineering Discovery Environment funded by the National Science Foundation.

 

"We are combining different kinds of seismic waves to render a more coherent image of the Earth," Chen said. "This process has been helped by supercomputing power that is provided by XSEDE."

 

"What is really new here is that this is an application of what is sometimes referred to as full waveform inversion in exploration geophysics," study co-author Jeroen Tromp said. Tromp is a professor of Geosciences and Applied and Computational Mathematics, and the Blair Professor of Geology at Princeton University.

 

In essence the application combined seismic records from thousands of stations for each earthquake to produce scientifically accurate, high-res 3-D tomographic images of the subsurface beneath immense geological formations.

"Grab your screwdrivers, makers! There’s a new, more powerful Raspberry Pi in town… The just announced Pi 2, which goes on sale today, adds a quad-core chip and double the memory to support more intensive processing tasks.

The Pi Foundation also reckons this sequel takes the Pi microprocessor “firmly into the PC space”, as they put it — in terms of power punch packed.

“With the Pi 1, there were people using it as a PC but you had to make allowances for the fact it was a $35 PC,” says Pi creator, Eben Upton, in an interview with TechCrunch. “The big difference with the Pi 2 is it’s a PC. It’s not a PC which is pretty good considering it cost you $35. It’s a PC that’s pretty good..."

Zinc oxide materials tapped for tiny energy harvesting devices

Zinc oxide materials tapped for tiny energy harvesting devices | Sciences & Technology | Scoop.it

"Today, we're surrounded by a variety of electronic devices that are moving increasingly closer to us - we can attach and wear them, or even implant electronics inside our bodies.

 

Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable and powered by ambient renewable energy.

This last goal inspired a group of Korea Advanced Institute of Science and Technology (KAIST) researchers to explore how the attractive physical features of zinc oxide (ZnO) materials could be more effectively used to tap into abundant mechanical energy sources to power micro devices. They discovered that inserting aluminum nitride insulating layers into ZnO-based energy harvesting devices led to a significant improvement of the devices' performance. The researchers report their findings in the journal Applied Physics Letters..."

Laser pulses used to track motion of electrons in metals with attosecond precision

Laser pulses used to track motion of electrons in metals with attosecond precision | Sciences & Technology | Scoop.it

"It is easy to measure electric current. But it is extremely hard to watch the individual electrons which make up this current. Electrons race through the metal with a speed of several million meters per second, and the distance they have to cover between two adjacent atoms is very small. This means that tiny time intervals have to be resolved in order to watch the electrons dashing through the metal.

 

Measurements in Garching (Germany) and theoretical calculations at the Vienna University of Technology (Austria) have now made this possible. As it turns out, the motion of the electrons in the metal is remarkably similar to ballistic motion in free space. The results have now been published in the journal Nature..."
