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 ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

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 ...

Investigators believe they finally have solved the infamous and gruesome 1991 killings of four teenage girls inside an Austin frozen yogurt shop, known as “The Yogurt Shop Murders,” after 34 years. On ...

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 ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

When four mothers in Southern California finally had their kids in school full-time, they didn’t look to fill their hours with Pilates or pickleball. They decided to investigate a murder. In the new ...
