A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Researchers have developed a powerful computational framework that shows how carefully optimized nanotube shapes can amplify ...

The killer was identified as Ernest Theodore Gable, who himself was murdered in 1987 at 36 years old. "The convergence of irrefutable DNA evidence, fingerprint analysis, compelling witness testimony, ...

Abstract: A specific limitation of spatial modulation (SM) is that the number of transmit antennas must be a power of two, otherwise it will cause a fractional bits problem. To solve this problem, ...

Supertwisted WS2 spirals can be synthesized at the edges of nanoribbons, where larger step heights or contact areas of the nanoribbons lead to larger twist angles. The photoluminescence properties of ...

You probably don’t need more time. By Jancee Dunn When I look back on all the major decisions I’ve dithered over, I could scream. It took me a decade to commit to becoming a parent. I wavered for a ...

President Trump claimed he has ended seven wars during a news conference in the United Kingdom. Since taking office, the U.S. has been involved in five ceasefires or peace agreements, though not all ...

The 1975 murder of a Maryland woman was finally solved with the help of an old cassette tape and a picture of the victim, authorities announced Tuesday. The cold case of Roseann Sturtz, who was ...

For years, a small but heavily engaged community has gathered online, entirely dedicated to the goal of identifying a single elusive song. On Monday, following an exhaustive search, they announced ...

Two New Orleans students who solved the Pythagorean theorem using trigonometry have had their discovery confirmed by the math community after their findings were published in the American Mathematical ...
