Modeling of a Single-Phase High-Voltage Power Supply for a Single Magnetron [PDF]

E3S Web of Conferences
Industrial microwave generators operating at 2.45 GHz commonly use magnetrons as microwave sources, requiring robust and reliable high-voltage (HV) power supplies. This paper presents a nonlinear electrical model of a single-phase HV power supply feeding

Bragg grating based integrated photonic Hilbert transformers

, 2013
Planar Bragg grating based photonic Hilbert transformers are experimentally demonstrated in this work. Planar Bragg gratings are utilized to implement a general Hilbert transform, a fractional order Hilbert transform and terahertz bandwidth Hilbert ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Experimental studies of influence of DC and AC electric fields on bridging in contaminated transformer oil

, 2015
Analysis of real operating condition revealed that HVDC transformers experience combined effect of DC biased AC electric field. The dynamics of pressboard particle in contaminated transformer oil under the influence of DC, AC and DC biased AC electric ...

INTERNAL RESONANCE FOR POWER TRANSFORMER INTERACTED WITH CABLE TRANSIENTS

Yanbu Journal of Engineering and Science, 2019
Power transformers may be subjected to switching surges or fault events that may be responsible for internal transformer resonance. This paper deals with two scenarios of cable-transformer resonance.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
