This paper describes a novel bandgap reference with high PSRR over a wide frequency range. The design utilizes an internally regulated supply voltage without high gain feedback loop. Thus improve PSRR ...

Radio telescopes saw a strange burst of unknown energy in June 2024. Now we know it was from Relay 2, an early ...

The 10-year survey is the primary mission of the Vera C. Rubin Observatory, located on a mountaintop at the edge of Chile’s ...

Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed ...

AFR's 3 kW Laser Cavity Component integrates a high power (kW) laser combiner and a fiber bragg grating in a compact package that reduces fiber splicing, improves electro-optical efficiency, and ...

They also want to share what they’re learning about the upper atmosphere by shooting massive amounts of radio waves at it.

High-frequency transformers (HFTs) are key devices in solid-state transformers (SSTs). Accurate prediction of the remaining life of the HFT is essential to ensure the reliability of the SST. The ...

Background High frequency chest wall oscillation (HFCWO) is standard treatment for airway clearance in the USA and has recently been introduced in the UK and Europe. There is little published research ...

Between 50 and 1,000 kilometers above our heads is the ionosphere, a layer of Earth's upper atmosphere consisting of charged ...

These antennas at the High-frequency Active Auroral Research Program (HAARP) facility in Alaska send powerful radio signals into Earth’s ionosphere so that scientists can learn more about it.

Cardiac tissue engineering could be useful for replacement and/or repair of diseased or malformed cardiac tissue. The creation of functional, biocompatible contractile tissues, however, remains ...
