Simple three-level neutral point voltage balance control strategy based on SVPWM [PDF]
, 2013 The unbalance of the neutral point voltage is an inherent problem of three-level neutral-point-clamped (NPC) inverter, the effect of neutral point voltage balancing which is caused by voltage vector is analyzed, and the relationship of the voltage offset

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

FEBS Open Bio, EarlyView.This pilot study investigates the potential of Generative AI to provide formative feedback to students. ChatGPT was prompted to provide feedback on Year 1 Bioscience essays, which were evaluated against established good feedback practices. GenAI‐authored feedback had useful elements, but was limited in scope. GenAI may have potential to provide instant,

The persistence of balance in geophysical flows [PDF]
, 2007 This paper introduces a novel, powerful way to understand the why geophysical flows are largely under the control of a single scalar field, the potential vorticity, a materially conserved dynamical tracer in the absence of viscous and diabatic effects ...

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Effect of Prandtl's ration on balance in geophysical turbulence [PDF]
, 2015 Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant no. EP/H001794/1).The fluid dynamics of the atmosphere and oceans are to a large extent controlled by the slow evolution of a scalar field called ...
