Optimal power system stabilizer tuning in multi-machine system via an improved differential evolution

open access: yes, 2008
Power system stabilizer (PSS) is one of the most important controllers in modern power systems for damping low frequency oscillations. Many efforts have been dedicated to design the tuning methodologies and allocation techniques to obtain optimal damping

An adaptive implicit surface reconstruction method for three-dimensional point cloud

open access: yesDianzi Jishu Yingyong, 2019
Based on adaptive octree and improved differential evolution algorithm, an implicit surface reconstruction method for three-dimensional point cloud data is presented.Firstly, the original point cloud is adaptively segmented by octree. Secondly, the local

An Improved Differential Evolution Scheme for Noisy Optimization Problems [PDF]

open access: yes, 2005
Differential Evolution (DE) is a simple and surprisingly efficient algorithm for global optimization over continuous spaces. It has reportedly outperformed many versions of EA and other search heuristics when tested over both benchmark and real world problems.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
