Wind Tunnel Investigation of Wake Characteristics of a Wing with Winglets

open access: yesEngineering Proceedings
Aircraft performance metrics such as range and endurance are highly dependent on induced and vortex drag. There is a close relationship between wake structure and aerodynamic performance.

Correlation between ore particle flow pattern and velocity field through multiple drawpoints under the influence of a flexible barrier

open access: yesOpen Geosciences, 2019
By means of similar tests, the stope room is scaled and the process of multiple-drawpoint ore drawing under the influence of a flexible barrier is simulated by the marking particle method.

Modeling the velocity field during Haines jumps in porous media

open access: yes, 2015
When nonwetting fluid displaces wetting fluid in a porous rock many rapid pore-scale displacement events occur. These events are often referred to as Haines jumps and any drainage process in porous media is an ensemble of such events.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Velocity and Pressure Field of Spilling Breakers

open access: yesCoastal Engineering 1980, 1980
The internal velocity and pressure fields of quasi-steady spilling breaking waves have been investigated experimentally. The internal flow fields are shown to be in qualitative agreement with a model proposed by Peregrine and Svendsen (1978). Furthermore a quantitative comparison is made with nonbreaking wave theories.

Reprocessing of three-decade GNSS observations: millimeter-level nonlinear terrestrial reference frame, global velocity field and plate motion model refinement

open access: yesGeo-spatial Information Science
The Terrestrial Reference Frame (TRF) is essential for solid Earth research, including geodesy and geodynamics, providing a unified spatiotemporal datum.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

A GPS velocity field for Fennoscandia and a consistent comparison to glacial isostatic adjustment models

open access: yes, 2014
In Fennoscandia, the process of Glacial Isostatic Adjustment (GIA) drives ongoing crustal deformation. Crustal velocities from GPS observations have proved to be a useful tool in constraining GIA models.
