Expanding on its full suite of RF Inductor design tools, Coilcraft has added an updated ADS Component Library to its selection of online 2D/3D, S-Parameter and SPICE Models. Coilcraft’s Component Library includes models of its RF and Spring inductors and integrates with Agilent’s Advanced Design System (ADS), helping engineers accurately simulate the performance of Coilcraft inductors in their circuit designs. After downloading the free ADS Component Library, users can select any Coilcraft part and place it into their design. Once placed, they can select their desired inductance value for simulation. S-Parameters are valid from 1 MHz to just above the SRF of the component, as defined on the respective product datasheet available on the Coilcraft Website. As with all Coilcraft products, free product evaluation samples are also available and shipped the same day when requested from the Coilcraft web site.
LONDON, (Reuters) – South African Caster Semenya’s long and controversial reign as the queen of middle distance running looks set to be ended this year not by a track rival but by a new hyperandrogenism rule that will stop her from running 800 and 1500 metres races. The IAAF will publish new rules today to prevent women with the condition, which produces higher than normal levels of testosterone and is deemed by the governing body to give them an unfair advantage, from running distances from 400m to the mile.The International Association of Athletics Federations would allow them to compete at international level only if they took medication to reduce naturally occurring levels of testosterone.Semenya, double Olympic and triple world champion over 800m and who completed the 800-1500 double at the Commonwealth Games this month, has always been a controversial figure in the sport as its authorities have sought a solution that respected her rights while also providing a “level playing field”. The 27-year-old’s powerful physique and deep voice, followed by the revelations of her hyperandrogenism, left some rivals complaining that they faced an impossible and unfair challenge.The IAAF’s previous attempts to regulate the issue fell foul of a Court of Arbitration for Sport ruling in 2015 following an appeal on behalf of Indian athlete Dutee Chand, who had been banned from competing because of her testosterone levels.The IAAF Council announced last month that following a review of available evidence it would revise its regulations, with the changes coming into force on Nov. 1. “All testosterone, either naturally occurring or artificially inserted into the body, provides significant performance enhancements,” IAAF head Seb Coe said at the time, while also going out of his way to stress that nobody was suggesting Semenya had done anything wrong. “We were asked by CAS to provide evidence of the magnitude of the advantage, which we now have,” he said.FEMALE CLASSIFICATIONMedia in the UK and South Africa yesterday published sections of the report ahead of its official release, revealing that the new hyperandrogenism regulations would include a separate female classification to be known as an Athlete with Differences of Sexual Development (DSD). “Experts consulted by the IAAF have gathered and reviewed all of the published evidence and data, which indicates that increasing the level of circulating testosterone from the normal female range to the normal male range leads to increased muscle mass and strength and higher haemoglobin levels,” the report, which has not been seen by Reuters, is reported to have said. “The result is these new regulations, which seek to facilitate the participation in the sport of athletes with DSDs on terms that preserve fair and meaningful competition in the female classification.“The significant over-representation of DSD athletes in certain events, and their success in those events, provides further indirect but strong corroboration of the above.“In addition, the IAAF has gathered observational data about the difference in performance levels of DSD athletes depending on whether or not their testosterone levels are suppressed.” The IAAF’s medical advisors have suggested the advantage held by DSD athletes is far less pronounced in short sprints or longer distance endurance races, leaving the door open for Semenya to move up to 5,000 or 10,000 metres if she desires.The South African began raising eyebrows when she won the world junior championships in 2008 and the senior world title the following year, with dramatic improvement in her times.The IAAF made Semenya take a sexual verification test, which was initially kept secret but revealed by the media in 2009. Since then virtually all of Semenya’s performances have been followed by questions about her sexual and physical status, but she has long stopped answering them.Reuters yesterday sought Semenya’s response to the IAAF’s decision through her manager but he did not immediately reply.
Related ABC News(NEW YORK) — Most of the nation has a quiet weekend ahead with no significant weather impacts in the forecast. A new system will bring some rain and cool conditions in the Northwest this weekend, while cool air also sinks into parts of the Midwest, Great Lakes and Northeast.On Saturday, temperatures in the 30s are expected in the Northern Plains and into parts of the Great Lakes. This cool air moves to the east on Sunday and Monday, with temperatures dipping down into the 30s across the Great Lakes and Ohio Valley.These temperatures are well below average, with a couple of record-low temperatures possible in the Great Lakes. The cooler air could also bring some scattered snow showers in the Ohio Valley and Great Lakes on Sunday morning.However, a major pattern change is coming next week with dramatically different weather in the forecast.Feeling like summerThe weather pattern will be changing dramatically over the next few days. As a result, severe weather is expected to ramp up significantly next week. This pattern will also bring the warmest air in over seven months to parts of the eastern U.S., with much of the East feeling like summer by the end of the week.Early next week, a new system will move into the Northern Plains. The system will force cooler and drier air to clash with warm and moist air in the Central and Southern Plains. This weather pattern means there is the potential for a multiday significant severe weather event.The first round of severe weather will begin on Monday with damaging winds, large hail and brief tornadoes likely from eastern South Dakota to western Texas, including Sioux Falls, South Dakota; Dodge City, Kansas; Amarillo, Texas; and Lubbock, Texas.On Tuesday, the activity begins to move into the Central Plains, clashing with very warm and moist air. Widespread severe storms will develop from Texas to Kansas — including Oklahoma City, Oklahoma; Wichita, Kansas; and Kansas City, Missouri — on Tuesday and especially Wednesday.Although particulars with the storm setup remain unknown, it appears increasingly likely that these storms could be robust and violent on Wednesday with strong tornadoes possible.The storms will likely move into parts of the Ozarks by Thursday, but there is uncertainty on the magnitude of the impacts of the severe weather right now.It is important to note that this is the time of year when strong and numerous tornadoes develop over the plains. Besides the severe weather outbreak just two weeks ago across the Gulf Coast, April has been very quiet in terms of tornadoes due to the sustained cool and dry air from the north.For parts of the central and eastern U.S. — including New York, Boston and Philadelphia — it is finally time to get your shorts and T-shirts out and put the coats away.A ridge of high pressure developing across the eastern U.S. means temperatures on Monday will be well into the upper 70s and 80s across much of the central United States. In the Northern Plains, 80-degree temperatures are 10 to 15 degrees above average.On Tuesday, the warmth expands to the East Coast, with widespread upper 70s and 80s expected from Texas to New England. Temperatures in the Midwest to the Northeast will be nearly 10 to 15 degrees above average — including in Chicago, Philadelphia, New York City and Boston.Another pulse of warm air heads toward the Northeast by the end of the week. Temperatures by the end of next week could be approaching 90 degrees across the entire Northeast. These forecast highs are nearly 20 to 25 degrees above average. The last time it was 90 degrees in New York was Sept. 24, 2017. For Boston, you have to go back to Aug. 22, 2017.A factor that could hold temperatures down locally would be any sea or bay breezes that develop, since water temperatures remain quite cold.
