TL;DR: In this article, the authors make initial steps toward an empirical model for ionospheric perturbations related to space weather events that are observable in the total electron content (TEC).

TL;DR: In this paper, Shen et al. proposed a chiral quark model with diquark pairing in spin-1 single-flavor, spin-0 two-flavour, and three-flavours channels, where the three light quark flavors are sequentially deconfined under increasing pressure in cold asymmetric nuclear matter.

TL;DR: An infrastructure exploiting the capabilities of both optical technologies for the realization of a modernized constellation of navigation satellites emitting highly synchronized signals is reviewed, and such infrastructure improves satellite navigation in terms intra-system synchronization, orbit determination accuracy, as well as system monitoring and integrity.

TL;DR: In this article, the occurrence rate of signal scintillations between the different global navigation satellite systems and their different signal frequencies was compared, and the overall influence of short scale ionospheric disturbances on the GNSS signals was estimated.
