By using satellite surveillance dilution of precision （SSDOP） as fitness function, an amplification method is proposed to optimize the reference stations distribution in the mainland of China. According to the curve of SSDOP changing with stations number, seventeen reference stations are needed in China. The locations of these seventeen stations are obtained by the amplification method. Experiments are made to verify the performance of SBAS with this stations distribution. The horizontal positioning accuracy is 2.77 meter, the vertical positioning accuracy is 0.88 meter, and the availability is better than 99%. These three indicators satisfy the requirements of CAT I.

Some studies have confirmed the neuroprotective effect of remote ischemic conditioning against stroke. Although numerous animal researches have shown that the neuroprotective effect of remote ischemic conditioning may be related to neuroinflammation, cellular immunity, apoptosis, and autophagy, the exact underlying molecular mechanisms are unclear. This review summarizes the current status of different types of remote ischemic conditioning methods in animal and clinical studies and analyzes their commonalities and differences in neuroprotective mechanisms and signaling pathways. Remote ischemic conditioning has emerged as a potential therapeutic approach for improving stroke-induced brain injury owing to its simplicity, non-invasiveness, safety, and patient tolerability. Different forms of remote ischemic conditioning exhibit distinct intervention patterns, timing, and application range. Mechanistically, remote ischemic conditioning can exert neuroprotective effects by activating the Notch1/phosphatidylinositol 3-kinase/Akt signaling pathway, improving cerebral perfusion, suppressing neuroinflammation, inhibiting cell apoptosis, activating autophagy, and promoting neural regeneration. While remote ischemic conditioning has shown potential in improving stroke outcomes, its full clinical translation has not yet been achieved.

The Satellite-based augmentation system(SBAS) is intended to provide real-time differential global navigation satellite system corrections with the high accuracy, availability, and integrity required for aviation applications. Since the performance of Satellite clock and ephemeris(SCE) corrections and Ionospheric range delay(IRD) corrections can vary dramatically depending on satellites and Ground reference stations(GRSs) geometry,therefore, we present a GRSs distribution optimized criteria and process to improve SBAS corrections *** present step-by-step optimized scheme using the average satellite surveillance dilution of precision and relative centroid metric availability of grid points as fitness values to determine the appropriate GRSs distribution to sufficiently meet the corrections requirements. The results show that the statistical mean RCM availability can reach more than 0.5518 for all IGPs and the coverage depth of GRSs in China and its surrounding areas is more than 25,which fully satisfies the requirement for solving SCE and IRD corrections.
