Instability of MHD couette flow of an electrically conducting fluid

open access: yesAIP Advances, 2018
We study the electrically conducting fluid stability of magnetohydrodynamic flow between parallel plates by Chebyshev collocation method by applied transverse magnetic field. Temporal growth is obtained by the governing equations.

A Corrective to Bovens and Hartmann's Measure of Coherence [PDF]

open access: yes, 2004
Bovens and Hartmann (2003a, 2003b) propose to analyze coherence as a confidence-boosting property. On the basis of this idea, they construct a new probabilistic theory of coherence.

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

The Ekman-Hartmann layer in MHD Taylor-Couette flow

open access: yes, 2007
We study magnetic effects induced by rigidly rotating plates enclosing a cylindrical MHD Taylor-Couette flow at the finite aspect ratio $H/D=10$. The fluid confined between the cylinders is assumed to be liquid metal characterized by small magnetic ...

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Lattice Boltzmann simulation of magnetic field effects on nanofluid [PDF]

open access: yes, 2014
This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the ...

Accuracy of Shack-Hartmann wavefront sensor using a coherent wound fibre image bundle

open access: yes, 2018
Shack-Hartmann wavefront sensors using wound fibre bundles are desired for multi-object adaptive optical systems to provide large multiplex positioned by Starbugs.

Modeling Acoustic Attenuation, Sound Velocity and Wave Propagation in Lithium‐Ion Batteries via a Transfer Matrix

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
“A simple 1D transfer matrix model of a battery is introduced and parametrized using harvested individual cell components at 0 % and 100 % SoC. This model allows for the calculation of group velocity and attenuation. The results of the model show good agreement with measured values, highlighting increased attenuation and group velocity at the ...

Force-detected nuclear double resonance between statistical spin polarizations

open access: yes, 2008
We demonstrate nuclear double resonance for nanometer-scale volumes of spins where random fluctuations rather than Boltzmann polarization dominate. When the Hartmann-Hahn condition is met in a cross-polarization experiment, flip-flops occur between two ...

Academic misconduct appeal services in China: Platform logics, self‐platformization and implications for integrity education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Academic misconduct appeal services have quietly emerged within China's education marketplace, with commercial agencies promoting themselves on social media to assist international students facing misconduct hearings. While existing research on academic integrity has emphasized prevention and detection, far less attention has been paid to what
