The 2018 GaN Power Electronics Roadmap [PDF]

, 2018
Gallium nitride (GaN) is a compound semiconductor that has tremendous potential to facilitate economic growth in a semiconductor industry that is silicon-based and currently faced with diminishing returns of performance versus cost of investment.

A Multilevel Active-Clamped Converter Topology—Operating Principle

IEEE Transactions on Industrial Electronics, 2011
This paper presents a novel multilevel activeclamped converter topology, which is an extension to m levels of the three-level active neutral-point-clamped topology. The operating principle is established through the definition of a proper set of switching states and a transition strategy between adjacent switching states.

Model predictive control for Active-Bridge-Active-Clamp (ABAC) converter [PDF]

, 2018
The Dual-Active-Bridge is a well-established isolated, bidirectional DC/DC topology suitable for applications where high efficiency, galvanic isolation and large voltage conversion ratios are required. However, in low voltage high power cases, the output

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Transcription initiation at a consensus bacterial promoter proceeds via a ‘bind-unwind-load-and-lock’ mechanism

eLife, 2021
Transcription initiation starts with unwinding of promoter DNA by RNA polymerase (RNAP) to form a catalytically competent RNAP-promoter complex (RPo). Despite extensive study, the mechanism of promoter unwinding has remained unclear, in part due to the ...
