A collaboration between EPFL and UCSB has developed a long-anticipated breakthrough, and demonstrated CMOS technology -- used for building microprocessors and memory chips -- that allows wafer-scale manufacturing of chip-scale optical frequency combs.
What The Study Did: Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn't reschedule once reopening occurred.
Using Kirigami, the Japanese art of paper cutting, a mechanical engineer at the University of Houston has developed a camera with a curvy, adaptable imaging sensor that could improve image quality in endoscopes, night-vision goggles, artificial compound eyes and fish-eye cameras.
Researchers at the Georgia Institute of Technology, Nokia Bell Labs, and Heriot-Watt University have found a low-cost way for backscatter radios to support high-throughput communication and 5G-speed Gb/sec data transfer using only a single transistor when previously it required expensive and multiple stacked transistors.
Engineers developed inexpensive methods to make "impossible materials" that interact in unusual ways with microwave energy. Thin film polymers inkjet printed with tiny component patterns collect or transmit energy with much greater selectivity, sensitivity, and power than conventional materials.
Smartphone apps have proved invaluable for helping people manage chronic pain during the COVID-19 pandemic, but researchers warn that the need for information sharing and education in this area is being neglected.
University of Rochester researchers describe the first demonstration of highly chirped pulses created by a using a spectral filter in a Kerr resonator, enabling them to widen a laser pulse wavefront by separating the beam's colors. The chirped pulses remain stable even with more than 90% energy loss.
Researchers have discovered a new and more efficient computing method for pairing the reliability of a classical computer with the strength of a quantum system.
Scientists at Tokyo Institute of Technology and NEC Corporation jointly develop a 28-GHz phased-array transceiver that supports efficient and reliable 5G communications. The proposed transceiver outperforms previous designs in various regards by adapting fast beam switching and leakage cancellation mechanism.
Researchers found differences in sociodemographic and clinical characteristics by entry location for SARS-CoV-2 testing within a safety-net health system. White and English-speaking individuals disproportionately initiated testing via telehealth visits, while black, Native American and non-English-speaking patients disproportionately initiated testing through the emergency department.
