Statistical Behavior of PMU Measurement Errors: An Experimental Characterization
IEEE Open Journal of Instrumentation and Measurement, 2022 Different power system applications based on synchrophasors measured in different nodes of the electric grid require information about the statistical distribution of the errors introduced by the phasor measurement units (PMUs).

Optimal choice of the number of even harmonics demodulated from the excitation current of a sensor for precise dc voltage component detection in low voltage distributive grid as a strategy for suppression of the systematic error due to the grid voltage fluctuation [PDF]
Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2018 This paper addresses the problem of suppression of a systematic measurement error during the detection of a parasitic DC voltage component, superimposed to an AC voltage. As a sensor the toroidal transformer is employed.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...
