Research on an Alpha Navigation Signal Detection Method Based on Multichannel Orthogonal Correlation
Publikováno v:
Applied Sciences, Vol 14, Iss 9, p 3620 (2024)
The Alpha navigation system is the only operating radio system based on very-low-frequency (VLF) signals that can be used to research VLF navigation, timing, and ionospheric characteristics. The detection of the Alpha navigation signal is the key ste

Background. Patients with congestive heart failure (CHF) are vulnerable to contrast-induced kidney injury (CI-AKI), but few prediction models are currently available. Therefore, we aimed to establish a simple nomogram for CI-AKI risk assessment for p
