Investigations on the performances of the electrical generator of a rim-driven marine current turbine” [PDF]

open access: yes, 2014
In this paper, the electrical generator of a rim-driven horizontal-axis current turbine is modeled in detail. Its main characteristics and performances are evaluated (efficiency, mass, cost, etc).

A generalized open-end winding conversion system using flying capacitor cells [PDF]

open access: yesElectric Power Systems Research, 2019
Abstract Over the years, industrial processes, renewable energy systems and electrification of transport systems have been pushing power electronics equipment towards higher power ratings, quality and faster dynamics. In this context, several multilevel converter structures were developed and became popular, such as neutral-point-clamped, flying ...

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

open access: yesFEBS 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 ...

Non-Intrusive Online Stator Temperature Estimation for Open-End Winding PMSM [PDF]

open access: yes2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
This paper proposes a new method for online identification of stator winding temperature for an open-end winding (OEW) permanent magnet synchronous motor (PMSM). The method exploits the zero sequence current (ZSC) due to the third harmonic back electromotive force (EMF) circulating in the system in order to estimate the phase resistance, which, in turn,

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Conceptual Design of a New Large Superconducting Toroid for IAXO, the New International AXion Observatory

open access: yes, 2012
The International AXion Observatory (IAXO) will incorporate a new generation detector for axions, a hypothetical particle, which was postulated to solve one of the puzzles arising in the standard model of particle physics, namely the strong CP problem ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Performance estimation of interior permanent-magnet brushless motors using the voltage-driven flux-MMF diagram [PDF]

open access: yes, 2006
The flux-magnetomotive force (flux-MMF) diagram, or "energy conversion loop," is a powerful tool for computing the parameters of saturated interior permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are not ...
