Centrifuge modelling of tunnelling with forepoling [PDF]

, 2016
Geotechnical centrifuge modelling provides a means by which geotechnical events and processes can be better understood. In particular, the technique has proved invaluable when investigating collapse mechanisms in small scale models that can be related ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Imaging spontaneous imbibition in full Darcy‐scale samples at pore‐scale resolution by fast X‐ray tomography [PDF]

, 2019
Spontaneous imbibition is a process occurring in a porous medium which describes wetting phase replacing nonwetting phase spontaneously due to capillary forces.

Soil Permeability in Centrifuge Modeling [PDF]

, 2019
If the same prototype soil and water are used for a centrifuge model, as it is generally accepted, the seepage velocity in the centrifuge is increased by N times earth gravity produced by the centrifuge environment. The increased seepage velocity produces a time scaling conflict between diffusion time and dynamic time.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Calibration method and effect factors of miniature pore water pressure transducer for geotechnical centrifuge modelling

Yantu gongcheng xuebao, 2020
Accurate measurement of pore water pressure is one of key technologies in geotechnical centrifugal modelling. Aiming at noticeable scatter of dynamic pore pressure measuring results in the recently repeated dynamic centrifugal liquefaction tests at home ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Ground collapse: effect of building position on tunnelling-induced soil movements

Geohazard Mechanics
The mechanisms of tunnelling-induced ground movements are important for risk assessments of tunnelling beneath masonry buildings with shallow foundations, including ground collapse disasters.

Centrifuge modelling of jacket foundation subjected to cyclic lateral loading in soft clay

Yantu gongcheng xuebao, 2018
The centrifugal model tests are carried out on a jacket foundation subjected to cyclic lateral loading in saturated soft clay to investigate the force and deformation characteristics of the jacket foundation under cyclic lateral loading from wind and ...
