Micro-macro mechanics of damage and healing in rocks

open access: yesOpen Geomechanics, 2021
This paper presents the state of the art of the theory of damage and healing mechanics, with a particular emphasis on the strategies available to relate the micro-scale of crystals, cracks and pores to the scale of a Representative Elementary Volume ...

A non-local continuum poro-damage mechanics model for hydrofracturing of surface crevasses in grounded glaciers

open access: yesJournal of Glaciology, 2020
Hydrofracturing can enhance the depth to which crevasses propagate and, in some cases, allow full depth crevasse penetration and iceberg detachment.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Parametrically homogenized continuum damage mechanics (PHCDM) models for composites from micromechanical analysis

open access: yesComputer Methods in Applied Mechanics and Engineering, 2019
This paper develops a parametrically homogenized continuum damage mechanics (PHCDM) model for unidirectional fiber-reinforced composites undergoing progressive damage.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Coupling crystal plasticity and continuum damage mechanics for creep assessment in Cr-based power-plant steel

open access: yesMechanics of materials (Print), 2019
To improve the design and safety of power plant components, long-term high-temperature creep behaviour of a power-plant material, such as Cr-based alloy, should be assessed.

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.

Numerical Analysis of the Damage Evolution in a Composite Pipe Joint Under Cyclic Static Axial Tension

open access: yesEngineering Transactions, 2003
The main goal of this paper is to present a computational analysis of damage evolution in adhesive joint connecting composite pipes subjected to cyclic static axial tension with constant amplitude.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

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.
