, 2001 Indoor performance is of great interest for the network operators, especially in office buildings and airports. Because current GPS receivers do not work indoors, the need of gaining positions by another tool is crucial. Ericsson Erisoft AB develops and markets TEMS Automatic, a system that measures the quality of service experienced by the users of ...

Steps Toward Vitrification and Banking of Coral Larvae Using Field‐Friendly Cryomesh Technology
Advanced Science, EarlyView.Cryomesh enables a low‐tech cryopreservation method, adding a valuable option to the coral reef conservation toolkit. The approach reveals how size, toxicity, and developmental stage govern larval survival, while modeling links cooling and rewarming rates to a theoretical upper volume limit.
