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

Voltage control method based on three‐phase four‐wire sensitivity for hybrid AC/DC low‐voltage distribution networks with high‐penetration PVs

open access: yesIET Renewable Power Generation, 2022
The increasing integration of distributed photovoltaics may further aggravate the over‐voltage and three‐phase unbalance issues of low‐voltage distribution networks with three‐phase four‐wire structures.

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 ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Application of the arithmetic optimization algorithm to the phase-balancing problem in three-phase asymmetric distribution networks

open access: yesTecnura
Objective: This article presents the application of the arithmetic optimization algorithm (AOA) to the phase balancing problem in three-phase asymmetric distribution systems. The algorithm is implemented in MATLAB and its performance is compared with the

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Load Flow Independent Method for Estimating Neutral Voltage in Three-Phase Power Systems

open access: yesEnergies, 2019
A precise modeling of three-phase power systems is of great importance due to its ability to represent load unbalance and asymmetry in system components.

Proceedings of the German-Japanese symposium on multi-phase flow [PDF]

open access: yes, 1994
Multi-phase flow with and without heat transfer has proved to be a true interdisciplinary science of paramount importance in industrial application such as power, refrigeration, process, petroleum, and environmental technologies.
