Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

CFT Narrowband Validation

AbstractWe report the detection of narrowband resonances in pulsar timing residuals at 6.1 nHz and 4.1 nHz, with quality factors Q ≈ 46 and Q ≈ 10, respectively. To assess statistical significance, we performed 2000 null simulations using time-shifted pulsar data, preserving noise characteristics while eliminating any coherent sky signal.

Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.

Kinetically Controlled Direct In Situ Photolithography of Perovskite Color‐Conversion Layers

Small, EarlyView.
Kinetically controlled direct in situ photolithography (KC‐ISP) enables high‐resolution patterning of micrometer‐thick perovskite color‐conversion layers. By regulating thiol–ene reaction kinetics and redistributing precursors within the polymer matrix, lateral curing is suppressed and spatially selective crystallization is achieved.
