A Three-Phase Frequency-Fixed DSOGI-PLL With Low Computational Effort
This paper offers a detailed analysis as well as a tuning and discretization approach of the presented frequency-fixed dual second order generalized integrator based phase-locked loop (FFDSOGI-PLL) for three-phase power systems.

The timing-recovery subsystem of the receiver determines the sampling instants that are used for data detection. Since these instants are discrete, any phase-locked-loop (PLL) that is embedded in the timing-recovery subsystem has fundamentally a discrete-time nature.

To handle the low frequency oscillations of the three-phase four-wire inverter grid-connected system caused by small phase-locked range, slow locking speed and large steady-state error of the traditional phase-locked loop, an improved phase-locked loop ...

Phase-Locked Loop with Inverse Tangent based Phase Detection
In this paper, a novel closed-loop synchronization algorithm is proposed based on the linear phase angle detection. The linear phase detection is performed by the inverse tangent (atan2) trigonometric function, while the frequency tracking is performed

A design methodology to enable sampling PLLs to synthesise fractional-N frequencies [PDF]
A novel design methodology is proposed to enable sampling phase-locked loops (SPLL) to synthesise fractional-N frequencies. To date, SPLL can only generate integer-N frequencies.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Linear phase demodulator including a phase locked loop with auxiliary feedback loop [PDF]
A phase modulated wave that may have no carrier power is demodulated by a phase locked loop including a phase detector for deriving an A.C. data output signal having a magnitude and a phase indicative of the phase of the modulated wave.

Insights Into the Antigenic Repertoire of Unclassified Synaptic Antibodies
ABSTRACT Objective We sought to characterize the sixth most common finding in our neuroimmunological laboratory practice (tissue assay‐observed unclassified neural antibodies [UNAs]), combining protein microarray and phage immunoprecipitation sequencing (PhIP‐Seq). Methods Patient specimens (258; 133 serums; 125 CSF) meeting UNA criteria were profiled;
