The Granular Origins of Aggregate Fluctuations [PDF]

This paper proposes that idiosyncratic firm-level fluctuations can explain an important part of aggregate shocks, and provide a microfoundation for aggregate productivity shocks. Existing research has focused on using aggregate shocks to explain business

Evaluation of the effect of segregation on coarse aggregate structure and rutting potential of asphalt mixtures using Dominant Aggregate Size Range (DASR) approach

, 2018
Segregation of asphalt mixtures indicates an artificially altered aggregate gradation, which consists of excessive coarse aggregates and insufficient fine aggregates that may result in premature failures and eventually reduce the pavement service life ...

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

FEBS 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 ...

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

Soil aggregate and organic nitrogen distributions as influenced by vermicompost application in vegetable greenhouse

Scientific Reports
Vermicompost application can improve soil physical structure and increase soil nitrogen (N) sequestration, yet its specific impact on soil aggregates in relation to changes in organic N fractions remains underexplored, especially in protected vegetable ...

Reconstructing enzyme evolution by protein engineering

FEBS 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 ...

Soil physical structure and aggregate stability dynamics during pit-mound microrelief development

Trees, Forests and People
Tree uprooting is a prevalent natural disturbance in primary forests, creating pit-mound microrelief that initiates a natural chronosequence of soil recovery.

Designing Optimal Integral Aggregate Structure

Journal of Technical Science and Technologies, 2015
In the absence of aprioristic information about the arrangement of the Support points in Integral Aggregate of nonlinear regressionanalysis there is a need for elimination of statistically non significant Reference point.

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 ...
