This week saw new revelations of election interference, both big and small: On one end of the spectrum, an alleged mother-daughter conspiracy to digitally rig a Florida high school's vote for homecoming queen.
“We came up with the technique by analyzing the sound spectrum of old-fashioned movies,” Klyce says, “and of course Citizen Kane was one that we modeled, and we kind of realized that that film sounded the way it did because of the limitations of the technology.”.
Wi-Fi 6E is a new standard for home networking gadgets—routers, security cameras, internet-connected doorbells—that allows these devices to utilize the 6-GHz wireless spectrum.This new 6-GHz band is also a higher-bandwidth slice of the wireless spectrum, so Wi-Fi 6E devices can send stronger, faster signals that contain more information.
While the advice about personal behavior spurred a negative response from people across the political spectrum, the effect was much stronger among Republicans than Democrats, said Risa Palm, a professor of urban geography at Georgia State and the lead author of the study.
Publishing in Nature today, physicists working on a CERN experiment called ALPHA have measured new properties of antihydrogen, the antimatter twin of the hydrogen atom.For the experiment, ALPHA’s physicists measured part of antihydrogen’s spectrum, the signature light that quantum particles emit.
In 2013, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (known as DSM-5) eliminated Asperger’s and redefined the autism spectrum as encompassing level 1 (“requiring support”) to level 3 (“requiring very substantial support”).“Technically, the DSM-5 essentially made Asperger’s a non-diagnosis ,” says Dania Jekel, executive director of the Asperger/Autism Network, which formed after Asperger’s first gained official status, from an outpouring of people seeking resources and a sense of community.
Justice Department officials said they approved the deal after they were convinced that the sale of Sprint’s so-called prepaid business, which includes the Boost Mobile and Virgin Mobile brands, and portions of Sprint’s wireless spectrum, would help Dish create a viable network.
This process is known as exciton fission and means that the solar cell is able to use high energy photons from the blue-green part of the visible spectrum. Baldo says that using tetracene could bump the theoretical energy efficiency limit up to 35 percent—higher than was ever thought possible for single-junction cells.
It's also possible that Amazon, or another company, could acquire rights to some of the wireless spectrum now licensed by the FCC to Sprint or T-Mobile, or even some of the infrastructure owned by those two carriers.
Birds see in four classes of color – blue, red, green and shorter wavelengths – violet or ultraviolet (UV) – depending on the species. Similar studies have looked at the role of the UV color spectrum in the way turkeys select their mates.
The FCC will continue to auction off rights to use the wireless spectrum during the shutdown because those auctions are funded by the auctions themselves.
NIWA freshwater ecologist Dr Michelle Greenwood is trying to find out how a change in the colour spectrum of street lights is affecting the tiny insects that live in and near freshwater.
The FCC regulates who can use which ranges, or bands, of frequencies to prevent users from interfering with each other’s signals.Low-Band FrequenciesBands below 1 GHz traditionally used by broadcast radio and television as well as mobile networks; they easily cover large distances and travel through walls, but those are now so crowded that carriers are turning to the higher range of the spectrum.Mid-Band SpectrumThe range of the wireless spectrum from 1 GHz to 6 GHz, used by Bluetooth, Wi-Fi, mobile networks, and many other applications.
Rather, these penguins, who were mummified by the cold, dry Antarctica environment, likely died from weather on the opposite end of the spectrum: two extremely rainy and snowy events that happened over the past 1,000 years, a new study finds.
