CPD-FCOS: A Scale-Isolated P2 Pathway for UAV Small-Object Detection
Small objects in UAV imagery fail for two coupled reasons. Repeated downsampling destroys their evidence—60.5% of VisDrone instances are COCO-small and the median object spans 26 pixels, so a typical target covers fewer than four cells at stride 8—and ...

Anomalies of land-atmospheric parameters in the 2023 Turkey earthquake (Mw7.8) using GNSS and ERA5
The Turkey earthquake (Mw 7.8) caused severe damage to Turkey and Syria on Feb. 6, 2023. It was observed that anomalies of land surface and atmospheric multi-parameters were associated with the land–atmosphere–ionosphere coupling (LAIC) mechanism.

Stochastic Models of Very High-Rate (50 Hz) GPS/BeiDou Code and Phase Observations
In recent years, very high-rate (10–50 Hz) Global Navigation Satellite System (GNSS) has gained a rapid development and has been widely applied in seismology, natural hazard early warning system and structural monitoring.
