Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reactive Power Compensation Scheme for Urban Rail Power Supply System Considering Main Substation Resource Sharing

open access: yesChengshi guidao jiaotong yanjiu
[Objective] The resource sharing among main substations in urban rail transit power supply system can lead to significant cost savings. In this context, it is essential to investigate reactive power compensation schemes for different phases of main ...

Utilizing the dead-time effect to achieve decentralized reactive power sharing in islanded AC microgrids

open access: yes, 2019
In islanded ac microgrids, distributed energy storage systems (DESSs) are normally coupled to the grid through voltage source inverters (VSIs). To improve the operation efficiency and to avoid overloading, it is desirable that VSIs can share active and ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Power-sharing: Institutions, Behavior, and Peace [PDF]

open access: yes, 2018
Grievances that derive from the unequal treatment of ethnic groups are a key motivation for civil war. Ethnic power-sharing should therefore reduce the risk of internal conflict.

Improved Optimal Control of Transient Power Sharing in Microgrid Using H-Infinity Controller with Artificial Bee Colony Algorithm

open access: yesEnergies, 2022
The microgrid has two main steady-state modes: grid-connected mode and islanded mode. The microgrid needs a high-performance controller to reduce the overshoot value that affects the efficiency of the network.

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Virtual Impedances Optimization to Enhance Microgrid Small-signal Stability and Reactive Power Sharing

open access: yes, 2020
Microgrid instability poses critical issues to the power delivery following a load change or a tripping event. In island operating mode lack of grid intensifies this challenge.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

A data-driven droop control strategy for reactive power sharing and stability enhancement in islanded AC microgrids

open access: yesInternational Journal of Electrical Power & Energy Systems
In islanded microgrids, distributed generation (DG) units employing conventional droop control often exhibit significant mismatches in reactive power sharing. This issue primarily arises from the mismatches in line impedances. These inaccuracies not only
