Electromagnetic ion cyclotron (EMIC) waves are an integral component of the Earth’s dynamic space environment. In order to quantify their effect, it is necessary to know their saturation amplitude, but in modeling studies it is usually the linear growth rate that is calculated and various assumptions need to be made in order to relate this growth rate to the final amplitude of the wave. Here, we perform a comparison of the saturation characteristics of EMIC waves using a 2.5-D electromagnetic hybrid PIC code, with the corresponding linear growth rates calculated with the hot-plasma dispersion solver of the HOTRAY code. We choose a set of values consistent with satellite observations for our nominal case, and explore the parameter space in the neighborhood of this nominal case, by varying the hot proton density and thermal anisotropy. We find that the saturation amplitudes increase monotonically, and the times to saturation decrease monotonically with increasing growth rates, independent of the values of density and anisotropy. Both the saturation amplitude and time to saturation curves can be fit by simple two-parameter models with acceptable errors. This result implies that within the limitations and caveats of the present study, the saturation amplitudes and time to saturation can be predicted with good accuracy based on the linear growth rates alone, which can be used directly in conjunctions with global ring current simulations to model the resultant effects on magnetospheric particles.
Many different times, said quarterback J.J. Razmovski, “I thought we were toast”, but he added that the coaches made sure that the players always believed that things could turn around – and they did.And a thrilling post-season that included a comeback from a 28-7 halftime deficit to shock Liverpool in the sectional semifinals continued at the Dome, where trailing Proctor three times did not keep the Northstars from finding its championship destiny again.For much of the night, what kept C-NS alive was the big plays of junior running back Mike Washington, who took off for touchdown runs of 59 and 73 yards straight up the middle, almost untouched. Whatever terms were used to describe the Cicero-North Syracuse football team’s Section III Class AA champions of 2017 and 2018, the words “unlikely” or “underdog” never entered the conversation. In 2017 and 2018, the Northstars were supposed to win, and did so, by big margins.On the other hand, when C-NS made its way past undefeated Utica Proctor 28-25 in Saturday night’s title game at the Dome at Syracuse University, it was difficult to find any player or fan who imagined that this would happen back in September, or even mid-October.Early in the season, the Northstars lost at Rome Free Academy, who finished the season 2-6. And when it met the two favorites in the AA title race, Liverpool and Proctor, it did not score a point in either game, shut out 10-0 by the Warriors and 32-0 by the Raiders. Tags: C-NSfootball This helped the Northstars overcome Proctor’s 12-0 lead established through two long first-half scoring drives of 85 and 87 yards where it used its ground attack to wear C-NS defenders down..Even after the Raiders regained the lead 18-14 in the third quarter on Patrick Minor’s six-yard scoring run, Washington, again finding a seam right up the middle of the field, dashed 55 yards to the end zone just one minute later.All that was a prelude to a wild fourth quarter that began with C-NS getting another big late-game turnover, freshman LaQuan Lemon intercepting Brandon Peterson’s screen pass at the Northstars’ 15 to thwart a Raiders drive.When the Northstars didn’t capitalize, Proctor, from its own 29, started another big march, converting a fourth down in its own end before Peterson completed two big passes to Saleh Eltayeb, one covering 22 yards, the other a 29-yard scoring pass with 4:38 left.Now trailing 25-21, C-NS turned to Razmovski, who to that point had mostly met with frustration any time he tried to throw. But from the Raiders’ 27, he threw 36 yards to Adron Pafford, followed by Washington going 30 yards on a sweep to the Proctor five.And then it got crazy.Pafford was called for offensive pass interference on a possible go-ahead TD catch with less than two minutes to play. Pushed back to the 25, the Northstars then moved closer when the Raiders were flagged for defensive pass interference.Thus, on third-and-goal from the Proctor 12, Razmovski rolled out right, saying that he “was just trying to make a play to win the game”, only to throw across his body toward the middle of the field, usually a no-no for any good quarterback since it often means a pass into traffic.Except that, this time, Razmovski’s throw was letter-perfect, finding Matt Klamm in the end zone with 1:26 to play.Proctor still had a chance, driving it inside C-NS’s 35, only to stall right there and have Peterson throw an incomplete pass on fourth down, setting off another championship celebration for the Northstars, one far sweeter than the previous two because of the way it rallied from season-long adversity to get it.Now C-NS can turn its attention back to the state playoffs, where next Saturday at 6 p.m. at Vestal it faces Section IV champion Corning. The winner gets Rochester McQuaid (Section V) or Lancaster (Section VI) in the Nov. 23 state semifinals.Share this:FacebookTwitterLinkedInRedditComment on this Story read more
The USC Price School of Public Policy is now ranked 2019’s second best graduate public affairs program in the nation by the U.S. News and World Report. Photo from Price School of Public Policy.Price ties for second with Syracuse University’s Maxwell School of Citizenship and Public Affairs. Price Dean Jack H. Knott said this reflects the dedication of the school’s students and faculty.“I attribute this steady ascent in the rankings to our exceptional faculty, students and staff who are deeply committed to fulfilling our mission to improve the quality of life for people and their communities, here and abroad,” Knott said in a news release. U.S. News determines its rankings based on peer reviews. Surveys are sent to 282 master’s programs nationwide and are filled out by deans, directors and department chairs. The respondents rank peer institutions on a scale of one to five which is then totaled and averaged to determine the nationwide ranking. According to U.S. News’ website, this year’s response rate was 49 percent.Individual programs within the school are also ranked. Price is ranked first for its urban planning program and ranked third for both its health policy and management program and its homeland and national security program. The school’s other programs ranked highly as well, with the lowest ranking being the public finance and budgeting program at 13th in the nation. Knott said it is “deeply gratifying” for Price to be ranked as one of the best in the nation. He recognizes that rankings do not entirely define a school, but said this news marks the upward trajectory of the Price School.“I am equally proud of who we are, what we stand for and the significant role each of us plays as part of our amazing USC Price School community,” Knott said. read more
Advertisement Avast has discovered a new form of malware on a number of popular apps throughout the Google Play Store, meaning that millions could be infected.The Anti-virus company discovered the exploit after a user posted a tip to its forums.The malware in question sits on a number of apps in the Google Play Store across a number of countries. What’s even more disturbing is that many of these apps have already been downloaded millions of times. – Advertisement – Most prominent of these infected apps is a card game called Durak, which has (according to Google’s own figures) attracted 5-10 million downloads.When you install an infected app, your phone’s behaviour will appear normal for as long as 30 days, which serves to mask the culprit of what comes next.After the 30 days, you start getting a barrage of ads every time you unlock your phone. These warn you about a security problem, tell you that your phone is out of date, or notify you that it is full of porn.The app in each case, offers a button to help fix this issue and when you agree, you will be redirected to more harmful software on fake app stores, including apps that send premium SMS messages or collect personal data.Google says, the apps listed in this report have now been suspended, but the worry is that there are more of them out there.Via Trusted Reviews read more
