CHICAGO Nike Air Max 270 Women's Triple White Australia , April 24 (Xinhua) -- Chicago Board of Trade (CBOT) grains futures closed mixed on Monday with soybean futures touching a three-week high on short-covering, as a weaker U.S. dollar raised hopes for fresh export sales.


Corn futures edged higher on support from fund short-covering and worries over a slow start to spring planting, while wheat declined on abundant stocks.


The most active corn contract for July delivery rose 1.75 cents, or 0.48 percent, to settle at 3.6555 dollars per bushel. July wheat delivery dropped 1.75 cents Nike Air VaporMax Moc 2 Sail Anthracite Australia , or 0.42 percent to 4.1925 dollars per bushel. July soybeans added 11 cents, or 1.14 percent, to 9.7175 dollars per bushel.


In the outside markets, the Brent crude oil market is 0.42 dollar per barrel lower, the U.S. dollar is lower Nike Air Max 95 Premium Neutral Olive Men's Australia , and the Dow Jones Industrials are 242 points higher.


Jason Roose, U.S. Commodities grain analyst, says that the grains are trading mixed Monday on a mixed weather outlook.


"Even though the southern states, Illinois and Nebraska will be above average for planting, the other states are behind average which will support the corn short term. Also Nike Air Max 1 Mars Stone Men's Australia , the weak dollar and strong exports are giving the corn and beans mild support today," Roose says.


The U.S. Department of Agriculture's weekly crop progress report is expected to show U.S. corn planting was 15 percent complete as of Sunday.


The Commodity Futures Trading Commission's weekly commitments of traders report also showed that non-commercial traders, a category that includes hedge funds, increased net short positions in CBOT wheat and soybeans.

SAN FRANCISCO, June 11 (Xinhua) -- Security researchers at the University of Washington (UW) have developed a new system called SeaGlass to detect anomalies in the cellular landscape that can indicate where and when cell phone surveillance devices are being used.


Described in a paper published in the June 2017 issue of Proceedings on Privacy Enhancing Technologies, the system was deployed during a two-month period with SeaGlass sensors installed in ride-sharing vehicles in Seattle and Milwaukee, resulting in the identification of dozens of anomalies consistent with patterns one might expect from cell-site simulators.


Cell phones are vulnerable to attacks from rogue cellular transmitters called International Mobile Subscriber Identity (IMSI) catchers, also known as cell-site simulators or Stingrays Nike Air Vortex Men's Orange Black Australia , surveillance devices that can precisely locate mobile phones, eavesdrop on conversations or send spam.


"Up until now the use of IMSI-catchers around the world has been shrouded in mystery, and this lack of concrete information is a barrier to informed public discussion," co-lead author Peter Ney, a doctoral student at the Allen School of Computer Science & Engineering at the UW Nike Air Vortex Grand Men's Purple Black Australia , was quoted as saying in a news release.


"Having additional, independent and credible sources of information on cell-site simulators is critical to understanding how - and how responsibly - they are being used."


Cell-site simulators work by pretending to be a legitimate cell tower that a phone would normally communicate with, and tricking the phone into sending back identifying information about its location and how it is communicating.


The portable surveillance devices now range in size from a walkie-talkie to a suitcase, and in price from several thousand to hundreds of thousands of U.S. dollars.


While law enforcement teams in the United States have used the technology to locate people of interest and to find equipment used in the commission of crimes, cyber criminals are deploying them worldwide Nike Epic React Flyknit Men's Olive Black Green Australia , especially as models become more affordable.


To catch these IMSI-catchers in the act, SeaGlass uses sensors built from off-the-shelf parts that can be installed in vehicles, ideally ones that drive long hours and to many parts of a city, such as ridesharing vehicles.


The sensors pick up signals broadcast from the existing cell tower network, which remain fairly constant. Then SeaGlass aggregates that data over time to create a baseline map of "normal" cell tower behavior.


The research team from the UW Security and Privacy Research Lab developed algorithms and other methods to detect irregularities in the cellular network that can expose the presence of a simulator.


These include a strong signal in an odd spot or at an odd frequency that has never been there before Nike Epic React Flyknit Women's Cargo Khaki Black Green Australia , "temporary" towers that disappear after a short time and signal configurations that are different from what a carrier would normally transmit.


For instance, around an immigration services building south of Seattle, the largest city in Washington state, run by the U.S. Department of Homeland Security, SeaGlass detected a cell tower that transmitted on six different frequencies over the two-month period.


That was notable because 96 percent of all other base cell towers broadcast on a single channel Nike Epic React Flyknit Men's Black White Australia , and the other 4 percent only used two or three channels.


In addition, the team detected an odd signal near the Seattle-Tacoma International airport with suspicious properties that were markedly different from those normally used by network providers.


Those patterns would make sense if a mimicking cell-site simulator were operating in those areas, the researchers noted.


"In this space there's a lot of speculation, so we want to.
