Supercritical Pitchfork Bifurcation of a Fractional‐Order Doubly‐Fed Induction Generator

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT To address the problem of the chaos phenomenon caused by the parameter drift of a doubly‐fed induction generator (DFIG) due to a changing operating environment, a fractional‐order stator voltage/flux‐oriented control model is developed, and bifurcation theory and numerical simulations reveal that the chaos mechanism originates from ...

Global importance of Amazonian freshwaters

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Amazonian freshwaters have large influences on regional and global climate, harbor remarkable and unique species, and are vital to human society. Nevertheless, as compared to their terrestrial counterparts in the Amazon, these freshwaters have received less attention from the international conservation community.

Starmerella bacillaris Yeast Derivatives for Improving Wine Stability: Effect of Cell Wall Composition and Extraction Techniques

open access: yesFood Frontiers, EarlyView.
Yeast derivatives from S. bacillaris showed superior protein haze reduction in wine compared to those from S. cerevisiae, with the most effective results from alkaline extraction. The consistently higher glucose content in S. bacillaris derivatives suggests the presence of (gluco)mannoproteins of high molecular weight, a feature not previously reported
