Computer scientists have created D-REC, an edge caching optimization method that uses a “digital twin” to forecast and improve data storage in wireless networks, thereby boosting speed and reliability.
At issue is something called edge caching. Caching refers to storing data on a server that a system or network thinks users will be using in the near future. This allows the system to meet user demands more quickly than if the system had to retrieve the data from the original source. Edge caching is when a system caches data in the server that is closest to the end user, such as computers that are incorporated into network routers or colocated with those routers.
“The method can be applied to any wireless network, depending on the system administrator or network operator’s needs,” says Liu. “D-REC can be adjusted depending on the needs of the user.” In addition, because D-REC’s digital twin focuses on predicting network behavior, it can identify potential problems in advance.

New method for generating monochromatic light in storage ringsWhen ultrafast electrons are deflected, they emit light—synchrotron radiation. This is used in so-called storage rings in which magnets force the particles onto a closed path. This light is longitudinally incoherent and consists of a broad spectrum of wavelengths.
