Vortex dynamics controlled by local superconducting enhancement

New Journal of Physics, 2019
A controlled local enhancement of superconductivity yields unexpected modifications in the vortex dynamics. This local enhancement has been achieved by designing an array of superconducting Nb nanostructures embedded in a V superconducting film. The most

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 ...

Geometry and dynamics of vortex sheets in 3 dimension [PDF]

Theoretical and Applied Mechanics, 2002
We consider the properties and dynamics of vortex sheets from a geometrical, coordinate-free, perspective. Distribution-valued forms (de Rham currents) are used to represent the fluid velocity and vorticity due to the vortex sheets. The smooth velocities

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

Molecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Quantum printing and induced vorticity in superconductors II: Laguerre-Gaussian beam

Physical Review Research
The challenge of controlling the quantum states of matter via light has been at the forefront of modern research on driven quantum matter. We explore the imprinting effects of structured light on superconductors, demonstrating how the quantum numbers of ...

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 ...

Discrete-time Point Vortex Dynamics

Journal of Optimization, Differential Equations and Their Applications
The paper examines a difference equation, analogous to the Helmholtz equation, which describes the point vortex dynamics on a plane under control. The dependence of the asymptotic behaviour of the moment of vorticity of a system of point vortices on the ...

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

On the beta-drift of an initially circular vortex patch [PDF]

, 2001
The nonlinear inviscid evolution of a vortex patch in a single-layer quasi-geostrophic fluid and within a background planetary vorticity gradient is examined numerically at unprecedented spatial resolution.

Fractional Vortex Dynamics in Two-Band Superconductors with Linear Normal Strips

Crystals
We investigate the impact of normal linear strips—both perpendicular and parallel to the direction of vortex motion—on the dynamics of fractional vortices in a two-band superconducting slab.
