High-Fidelity Voltage-Behind-Reactance Model of Electrically Excited Synchronous Machines Using Flux Maps

IEEE Open Journal of Industry Applications
Electrically excited synchronous machines (EESMs) have historically been used as efficient and reliable synchronous generators. However, the actual need for cost-effective, sustainable motors without rare-earth magnets has notably increased the interest ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Speedups of deterministic machines by synchronous parallel machines

Proceedings of the fifteenth annual ACM symposium on Theory of computing - STOC '83, 1983
The paper presents new speedups of deterministic multitape Turing machines by both fixed and variable structure parallel machines. Namely, it is shown that DTIME(T)\(\subseteq ATIME(T/\log T)\) and DTIME(T)\(\subseteq PRAM\)-time(\(\sqrt{T})\). These improve many previously known results.
