Design and analysis strategies for robust microbiome ageing research

FEBS 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

Multi-parametric deformed Heisenberg algebras: a route to complexity [PDF]

Journal of Physics A: Mathematical and General, 2001
We introduce a generalization of the Heisenberg algebra which is written in terms of a functional of one generator of the algebra, $f(J_0)$, that can be any analytical function. When $f$ is linear with slope $θ$, we show that the algebra in this case corresponds to $q$-oscillators for $q^2 = \tan θ$.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Dynamic processes in surface layers of parts as a source of their multicycle failure under friction and wear

Проблеми трибології
During the operation of various machines and mechanisms, oscillatory movements may occur, excited by a non-stationary friction characteristic. These oscillations appear either at the contact area of two parts or in the zone located ahead of the moving ...

Rapid Parametric CAx Tools for Modelling Morphing Wings of Micro Air Vehicles (MAVs)

Aerospace, 2023
This paper shows a series of tools that help in the research of morphing micro air vehicles (MAVs). These tools are aimed at generating parametric CAD models of wings in a few seconds that can be used in aerodynamic studies, either via CFD directly using

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

A hierarchical non-parametric method for capturing non-rigid deformations [PDF]

Image and Vision Computing, 2005
We present a novel approach for measuring deformations between image patches. Our algorithm is a variant of dynamic programming that is not inherently one-dimensional, and its scores are on a relative scale. The method is based on the combination of similarities between many overlapping sub-patches.
