Terrestrial and satellite communications, tactical data links, positioning, navigation, and timing (PNT), as well as distributed sensing will continue to require precise timing and the ability to synchronize and disseminate time effectively.However, the supply of space-qualified clocks that meet Global Navigation Satellite Systems (GNSS)-level perf
The interest in the use of ceilometers for optical aerosol characterization has increased in the last few years.They operate continuously almost unattended and are also much less expensive than lidars; hence, they can be distributed in dense networks over large areas.However, due to kids shoes the low signal-to-noise ratio it is not always possible
By the advent of the Bauhaus, the notion of design did engage in a two-track operation.Without dissociating itself from themes central to the formation of the architectural discipline, the concept of design, on the one hand, had to recode and at Lower Slide Tube times delete thematic that had attained visibility in the context of labour and skills
Abstract Objective The Polycomb Repressive Complex 2 (PRC2) regulates neural stem cell behaviour during development of the cerebral cortex, yet how the loss of PRC2 developmentally influences cell identity in the mature brain is poorly defined.Using a mouse model in which the PRC2 gene Embryonic ectoderm development (Eed) was conditionally deleted
