Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

, 2003
Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure. The log permeability

Fluid–Structure Interaction and Deformation Modes of UAV Liquid-Filled Tanks Subjected to Dual-Projectile Impacts with Varying Spatiotemporal Parameters

Drones
High-velocity multi-projectile impacts from accidental external debris (e.g., uncontained engine debris or runway stones) on the liquid-filled fuel tanks of modern unmanned aerial vehicles (UAVs) induce complex Fluid–Structure Interaction (FSI) and ...

REAL-TIME MONITORING DEFORMATION OF BUILDING USING PHOTOGRAPHY DYNAMIC MONITORING SYSTEM

Civil Engineering Journal, 2021
The spatial structure building is a type of building system; it is necessary to monitor deformation to determine its stability and robustness. Under the dynamic deformation of structures, it is challenging to determine appropriate zero image (the ...

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

Dynamic strength of fly ash-modified loess subgrade under influences of drying-wetting cycle

Yantu gongcheng xuebao, 2020
The traffic load and the drying-wetting cycle have an important influence on the strength characteristics and stability of fly ash-modified loess subgrade. To illustrate the influences of drying-wetting cycle on the strength of the fly ash-modified loess,

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 ...
