A compressive phase-locked loop [PDF]
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012 We develop a new method for tracking narrowband signals acquired via compressive sensing. The compressive sensing phase-locked loop (CS-PLL) enables one to track oscillating signals in very large bandwidths using sub-Nyquist sampling. A key feature of the approach is the fact that we perform the frequency tracking directly on the compressive ...

Radar Waveform Generator with Fuzzy Frequency Regulation [PDF]
International Journal of Telecommunications: The Phase-Locked Loop (PLL) is a common functional component in many electrical systems. Phase-locked loops (PLLs) are closed-loop feedback-driven devices producing a signal depending on the frequency and phase of reference sig-nal that comes in.

Structural Resemblance Between Droop Controllers and Phase-Locked Loops
IEEE Access, 2016 It is well known that droop control is fundamental to the operation of power systems and now the parallel operation of inverters, while phase-locked loops (PLLs) are widely adopted in modern electrical engineering.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using
