Electromechanics of graphene spirals

AIP Advances, 2014
Among the most fascinating nanostructure morphologies are spirals, hybrids of somewhat obscure topology and dimensionality with technologically attractive properties.

Reversing downward performance spirals [PDF]

, 2013
Research has typically portrayed downward performance spirals as inevitable following initial failure experiences. On the basis of social identity theorizing, we provide a prescription for reversing these spirals.

The fractal structure of elliptical polynomial spirals [PDF]

, 2022
We investigate fractal aspects of elliptical polynomial spirals; that is, planar spirals with differing polynomial rates of decay in the two axis directions.

Revisiting the Equipartition Assumption in Star-Forming Galaxies

Galaxies, 2019
Energy equipartition between cosmic rays and magnetic fields is often assumed to infer magnetic field properties from the synchrotron observations of star-forming galaxies. However, there is no compelling physical reason to expect the same.

Information Transmission Concept Based Model of Wave Propagation in Discrete Excitable Media

Nonlinear Analysis, 2004
A new information transmission concept based model of excitable media with continuous outputs of the model’s cells and variable excitation time is proposed. Continuous character of the outputs instigates infinitesimal inaccuracies in calculations.

Spirals in Galaxies

Annual Review of Astronomy and Astrophysics, 2022
Spirals in galaxies have long been thought to be caused by gravitational instability in the stellar component of the disk, but discerning the precise mechanism had proved elusive. Tidal interactions, and perhaps bars, may provoke some spiral responses, but spirals in many galaxies must be self-excited.
