Controlled symmetry breaking and vortex dynamics in intersecting flows

The Physics of Fluids, 2019
Vortices are a ubiquitous feature in complex flows and turbulence, but their dynamics are challenging to study due to their typically transient nature. Here, we perform a detailed study of the vortex dynamics and interactions associated with a symmetry ...

Vortex dynamics and Lagrangian statistics in a model for active turbulence [PDF]

The European Physical Journal E : Soft matter, 2017
Cellular suspensions such as dense bacterial flows exhibit a turbulence-like phase under certain conditions. We study this phenomenon of “active turbulence” statistically by using numerical tools. Following Wensink et al. (Proc. Natl. Acad. Sci.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Investigation of vortex dynamics and effects on a wall induced by a cavitation bubble near a hemisphere on the wall [PDF]

International Journal of Fluid Engineering
Cavitation-induced damage in hydraulic machinery is primarily caused by bubble collapse that generates high-speed jets and vortex structures. The present study employs a compressible two-phase flow model and a third-generation vortex identification ...

Dynamical influence of vortex-antivortex pairs in magnetic vortex oscillators

, 2015
We study the magnetization dynamics in a nanocontact magnetic vortex oscillators as function of temperature. Low temperature experiments reveal that the dynamics at low and high currents differ qualitatively.

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

FEBS 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 ...

Relaxation of twisted vortices in the Faddeev-Skyrme model

, 2003
We study vortex knotting in the Faddeev-Skyrme model. Starting with a straight vortex line twisted around its axis we follow its evolution under dissipative energy minimization dynamics. With low twist per unit length the vortex forms a helical coil, but

Non-linear vortex dynamics and transient effects in ferromagnetic disks [PDF]

, 2009
We report a time resolved imaging and micromagnetic simulation study of the relaxation dynamics of a magnetic vortex in the non-linear regime. We use time-resolved photoemission electron microscopy and micromagnetic calculations to examine the emergence ...

Digital twins to accelerate target identification and drug development for immune‐mediated disorders

FEBS Open Bio, EarlyView.
Digital twins integrate patient‐derived molecular and clinical data into personalised computational models that simulate disease mechanisms. They enable rapid identification and validation of therapeutic targets, prediction of drug responses, and prioritisation of candidate interventions.
