Search-and-rescue algorithm identifies hidden 'traps' in ocean waters(图)
Search-and-rescue algorithm identifies hidden traps ocean waters
2020/6/5
When an object or person goes missing at sea, the complex, constantly changing conditions of the ocean can confound and delay critical search-and-rescue operations.Now researchers at the Massachu...

undersea kelp forest missing nitrogen
2019/10/28
Plants need nutrients to grow. So scientists were surprised to learn that giant kelp maintains its impressive growth rates year-round, even in summer and early fall when ocean currents along the Calif...

On the heels of their participation in the historic research that resulted in the detection of gravitational waves, West Virginia University astrophysicists continue to plow new ground ...
In search of compromise among climate risk management strategies
search of compromise climate risk management strategies
2016/4/13
Balancing the impacts of climate change risks for all involved may not be within the realm of economics or physics, but a novel approach may help to achieve a better compromise, according to Penn Stat...

Search Technique Helps Researchers Find DNA Sequences in Minutes Rather Than Days
Researchers DNA Sequences Minutes Rather Than Days
2016/2/23
Database searches for DNA sequences that can take biologists and medical researchers days can now be completed in a matter of minutes, thanks to a new search method developed by computer scientists at...
In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Boosting search by rare events
Random search algorithm combination nonequilibrium random random algorithm
2015/8/21
Randomized search algorithms for hard combinatorial problems exhibit a large variability of per- formances. We study the different types of rare events which occur in such out-of-equilibrium stochasti...
