A new collaboration with Alphabet's Wing will only deliver sandwiches. It demonstrates the tricky parts of taking to the sky. Starting today, eager customers of the US pizza restaurant chain Papa Johns living in one corner of southern North Carolina will have the opportunity to receive their food from the sky, thanks to a new collaboration with Alphabet's drone company, Wing . But Papa Johns' signature pizzas won't be on offer. Instead, drone-loving North Carolinians will have to choose between three kinds of sandwiches, a newer product for the fast-food chain: Philly cheesesteak, chicken bacon ranch, or steak and mushroom varieties.

Since the PDE in Eq. 5 in the main manuscript is equivalent to the E-L equation of the quadratic

The birds can make good pets, but only if taken care of properly. Breakthroughs, discoveries, and DIY tips sent six days a week. Rescuers in North Carolina recently saved over 500 pigeons from a home in Greensboro. Guildford County Animal Services and two other bird rescues based in Charlotte initially believed that the call was for about 300 birds . Instead, they found about 550 pigeons inside of a shed behind the home, hidden from the street.

Iran's supreme leader, Ayatollah Ali Khamenei, in his secret hideout these days, knows he is now a marked man. He will not be sitting on his veranda anytime soon. When discussing what the United States might do next to help the protesters in Iran, US President Trump has mentioned Qassem Soleimani and Abu Bakr al-Baghdadi. The former, Iran's all-important military strategist in the Middle East, was killed on 3 January 2020 in a drone strike just outside Baghdad's international airport on the president's order. The latter, who was the leader of IS, killed himself and two children by detonating a suicide vest on 27 October 2019 when US forces raided his hideout in northern Syria after the approval of the president.

Scientists Thought Parkinson's Was in Our Genes. New ideas about chronic illness could revolutionize treatment, if we take the research seriously. Amy Lindberg spent 26 years in the Navy and she still walked like it--with intention, like her chin had someplace to be. But around 2017, her right foot stopped following orders. Lindberg and her husband Brad were five years into their retirement. After moving 10 times for Uncle Sam, they'd bought their dream house near the North Carolina coast. They had a backyard that spilled out onto wetlands. From the kitchen, you could see cranes hunting. They kept bees and played pickleball and watched their children grow. But now Lindberg's right foot was out of rhythm. She worked hard to ignore it, but she couldn't disregard the tremors.

The University of North Carolina has placed Asian and Middle Eastern Studies professor Dwayne Dixon on leave after his ties to the far-left gun club Redneck Revolt were exposed.

A college seafood forensics class investigated some fishy labelling. Breakthroughs, discoveries, and DIY tips sent every weekday. Sharks have been swimming in Earth's seas over 450 million years, but some struggling shark species may be ending up on grocery store shelves, in fish markets, and even sold online. Meat from shark species at risk of extinction is still available for sale in the United States, despite lawmaker's best efforts. "We found critically endangered sharks, including great hammerhead and scalloped hammerhead, being sold in grocery stores, seafood markets, and online," said Dr. Savannah J. Ryburn, a marine ecologist at University of North Carolina at Chapel Hill and co-author of a small study recently published in "Of the 29 samples, 93 percent were ambiguously labeled as'shark,' and one of the two products labeled at the species level was mislabeled." In the new study, a seafood forensic class at UNC bought 30 different shark products-19 raw steaks and 11 packages of shark jerky.

Then p E r Y |Z,A " a s is obtained from the regression forest [ 4 ] on Y Z with the dataset tp y We refer to [ 3 ] for more discussions about the case of misspecifying the main effect, and the corresponding robust and efficient method to solve the misspecification problem. A.2 Implementation details for the adaptive proximal gradient algorithm Recall that U " diag pX The main steps of the proposed algorithm for SCAF are summarized as below. In particular, the experiments were run on a Linux-based computing server.
