Variable Flux Memory Machines for Electric Vehicles: A Comparative Study [PDF]
EPJ Web of ConferencesThis paper overviews different synchronous machine types and topologies applied to electric vehicles (EV) traction. The very widespread permanent magnet synchronous machine (PMSM) and wound field synchronous machine (WFSM) are first compared in terms of ...

Internal Induced Voltage Modification for Current Limitation in Virtual Synchronous Machine
Energies, 2022 Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of

Efficient Synchronous Byzantine Consensus [PDF]
, 2017 We present new protocols for Byzantine state machine replication and Byzantine agreement in the synchronous and authenticated setting. The celebrated PBFT state machine replication protocol tolerates $f$ Byzantine faults in an asynchronous setting using $

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

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 ...
