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.

Phase jitter dynamics of first-order digital phase-locked loops with frequency-modulated input [PDF]
, 2008 IEEE International Symposium on Circuits and Systems (ISCAS), Seattle, USA, 18-21 May 2008Inherent to digital phase-locked loops is frequency quantization in the number-controlled oscillator which prevents the loop from locking exactly onto its reference

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Advanced Engineering Materials, EarlyView.Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design
