By Dialogo March 27, 2012 European researchers said on March 22 they have created a device invisible to a static magnetic field that could have practical military and medical applications. Fedor Gomory and colleagues in Slovakia and Spain designed a cloak for a direct current (DC) magnetic field that is static and produced by a permanent magnet or coil carrying a direct current. DC magnetic fields are used in MRI imaging devices, in hospitals and in security systems, such as those in airports. The researchers’ device, described in a study in the March 23 edition of the journal Science, features a cylinder with two concentric layers. While the inner layer consists of a superconducting material that repels magnetic fields, the outer layer is a ferromagnetic material that attracts them. Placed in a magnetic field, the device has no effect on the field lines, showing neither a shadow nor a reflection. So an object inside the device cannot be detected. “There are many applications – for some cars, ships or a submarine,” said study co-author Alvaro Sanchez of the Autonomous University of Barcelona. He told AFP the device could also be used for patients who have a pacemaker and need a MRI of a knee or other body part, so the image would not be distorted. Because it is made from commercially available materials, as well as operating under relatively strong magnetic fields and relatively warm liquid nitrogen temperatures, the device could easily be put to practical use, according to the authors. “For the submarine, you have to make a shell around the submarine that will make the submarine magnetically undetectable,” said Sanchez. “This could also be used to protect some (military and medical) equipment against electromagnetic disturbances.”
Whenever new stocks come in, theyimmediately run out due to high demand, he added.(With a report from PNA/PN) On March 13, DTI-Negros reported that a huge supermarket here displayed shelves empty of rubbing alcohol stocks, although various brands of bar soaps were readily available. The said establishment actually limits selling of rubbing alcohol to only three bottles per customer, based on the notices posted on its shelves. Moreover, Amihan said stocks of face masks are still limited especially in pharmacies here. “Generally, there are no available stocks in the province now,” he said. “So far, there’s no panic buying inNegros Occidental, but a significant increase in the purchase of alcohol andhand sanitizers has been observed,” Amihan said. Some consumers, however, have reportedlycomplained about stores imposing such limits. BACOLOD City – The Department of Tradeand Industry-Negros Occidental welcomed the decision of stores in this provincein limiting the volume of rubbing alcohol and hand sanitizers that customersmay purchase amid the coronavirus disease 2019 scare. According to Romel Amihan, head ofConsumer Protection Unit of DTI-Negros Occidental, the self-regulation willprevent consumers from hoarding the said products. In another shopping mall, meanwhile, its stores are limiting purchases of the said product to only two bottles per person. Display shelves for rubbing alcohol in a supermarket in Bacolod City on March 13 were empty, despite limiting purchases of it to three bottles only per customer. PNA
Famed statistician Nate Silver spoke to students and faculty in Bovard Auditorium on Friday morning in a presentation titled “Baseball and Politics are Data Driven.”Numbers game · Writer and statistician Nate Silver speaks to students about the process of predicting outcomes on Friday at Bovard Auditorium. – Ralf Cheung | Daily TrojanSilver’s presentation was the first in a yearlong series of events made possible by the Dennis F. and Brooks Holt Distinguished Lecture, a speaker’s series. The event, put on by the Bedrosian Center on Governance and the Price School of Public Policy, drew students, faculty and members of the public for an hour-long lecture and Q & A with Silver.Known for his extremely accurate predictions of election results over the last few years, Silver sold his original election prediction blog “538” to The New York Times, and later sold to ESPN.He first gained national attention in 2008 when he correctly predicted both the primary election results and the presidential winner in 49 out of 50 states. In 2012, Silver topped his previous record and perfectly predicted the electoral map. Now, he’s taking the 538 blog to ESPN to bring his statistical knowledge to baseball.Silver said his success stems from his ability to not only accurately interpret statistics, but also his ability to communicate this knowledge to others.“As a statistician, you have to understand that however interesting your finding might be based on the statistical evidence, it won’t persuade anyone unless you have a wider audience,” he said. “I’m definitely far from the best statistician in the world, and I’m far from the best writer, but the overlap of those skills is what characterizes what I’ve tried to do.”Silver began the presentation by describing the role technologies such as the printing press and the Internet have played in society. He discussed the importance of finding data that shows causation, not just correlation, the subject of his most recent book, The Signal and The Noise: Why Most Predictions Fail — But Some Don’t.He concluded with a series of suggestions to help students navigate the data minefield and be aware of misleading information. Using a combination of graphs, jokes and well-timed Notre Dame jabs, Silver presented a lecture many students found entertaining.Jack Knott, dean of the Price School, says making his expertise accessible is what sets Silver apart.“Nate would be a great teacher. He is able to make statistics relevant to not just focusing on political elections, but because of his expertise in things like baseball and poker, he has a very special ability not only to do high level statistical analysis but to also communicate it in a way to a much broader audience,” Knott said.Christian Patterson, a junior majoring in political science, said Silver’s unique style made the lecture engaging and fun.“I thought that he was a very talented speaker,” he said. “His presentation made a very strong case for using statistics as a means of predicting election results.”Knott also says that Silver’s outlook is the same view the Price School tries to instill in its students.“Evidence-based public policy decision making is hugely important for our country — it’s not based just on ideology, or one partisan way of looking at something,” he said. “We offer courses that teach students to think in a probabilistic, statistical way about policy issues and about the role of information and the news media in information and decision making.”Cat Duffy, a first year doctoral student in the Annenberg School for Communication and Journalism, agreed.“With the explosion of social media and the 24-hour news cycle, individuals are bombarded with information that is unfortunately presented as definitive fact, even when it lacks evidentiary proof,” Duffy said. “It’s important for students to recognize that being skeptical can be a virtue and recognizing that ‘not all information is created equal’ to ensure they make better and more informed decisions about the world around them.”For Silver, statistics is not just about data, but also the perspective it can provide on how humans interact with their environment.“To me, statistics do not just mean numbers,” he said. “It means an empirical way of looking at the world.”Follow Nathaniel on Twitter @haas4prez2036
Expo Center at South Florida Fairgrounds PALM BEACH COUNTY – Palm Beach County is in the process of implementing a plan to stage a field hospital at the South Florida Fairgrounds.Palm Beach County has multiple plans for multiple hazards and is always refining and testing these plans. With the assistance of the state, this hospital will be setup in case there is a significant surge in hospitalizations due to COVID-19.Emergency Management Director Bill Johnson explains the rationale behind the planning: “Palm Beach County has to take into consideration many possible scenarios in response to emergencies. Some of these responses require days of planning and setup and this requires us to implement a plan even before it is apparent that there is a need. This is a normal occurrence in emergency management and does not guarantee these worst-case scenarios will come to pass.”During his press conference in Miami, Governor Ron DeSantis stressed that there are at least five field hospitals being planned around the state, but at this time there is no need for these hospitals.The state as a whole has nearly forty-two percent available capacity in Florida hospitals and Palm Beach County currently has over forty-six percent of hospital beds available.Once the decision is made to open the field hospital, it will be made public through the media. This hospital will not be accessible to the public and will be used to take the pressure off of local hospitals that have a surge of incoming patients due to COVID-19.
Watch Live Next Game: Preview Drake continues its road trip at Illinois on Sunday afternoon. First kick with the Redbirds will be 2 p.m. and the match will be broadcast on The Valley on ESPN3. Following Sunday’s match, the Bulldogs will close the regular season against Loyola on Oct. 26 at 4 p.m. at the Cownie Soccer Complex. Print Friendly Version The Valley on ESPN3 Live Stats at Illinois State 10/22/2017 – 2 p.m. SPRINGFIELD, Mo. – The Drake University women’s soccer team battled Missouri State to a scoreless draw on Tuesday night in Missouri Valley Conference action at Allison South Stadium. Drake (11-3-2, 4-0-1 MVC) outshot Missouri State (6-9-1, 2-2-1 MVC), 23-12, including 11-7 shots on goal in its third match in seven days. The Bulldogs backline and senior goalkeeper Haley Morris (Clive, Iowa) recorded their sixth shutout this season. Morris finished with seven saves. Seniors Kasey Hurt (Ankeny, Iowa), Brooke Salisbury (Kearney, Mo.) and Ali Smith (Lenexa, Kan.) each recorded two shots on goal. Salisbury had one of her shots pushed by the MSU goalkeeper Lexi Palacio, into the crossbar and Smith just missed a header shot off a corner kick. Junior Alyssa Brand (Skokie, Ill.) had a game-highs seven shots, including two shots on goal. Full Schedule Roster “We didn’t do a good enough job in the first half of adjusting in the run of play of breaking down their backline,” said head coach Lindsey Horner. “We continued to make the same mistake over and over again. We were far better in the second half and overtime once we established some movement patterns and fixed our timing in the attack. I’m very proud of our players for playing three games in seven days, including two long road trips, and coming down here and getting a shutout on the road. A few months ago, we would have been very pleased with this road point, but what I love about our players is that they’re disappointed that we got shutout and left two points on the table. Haley made a great save tonight, and our back four were once again tremendous. At this point we need some rest and to fine tune our own game prior to Illinois State. We have to stay hungry and continue to strive for our best games as a team as we approach the end of our regular season.”
