In referendum elections, voters are often required to register simultaneous votes on multiple proposals. The separability problem occurs when a voter’s preferred outcome on one proposal depends on the outcomes of other proposals. This type of interdependence can lead to unsatisfactory or even...

We propose the Langevin-type microscopic equations of motion for magnetic fluids. Magnetic fluids are modeled as an ensemble of interacting ferromagnetic nanoparticles suspended in a viscous fluid. The present model is described in terms of position vectors of nanoparticles and orientation...

We present a model equation that describes nucleation and growth of hemispherical nanoclusters or islands deposited on a substrate for the small surface coverage case. The model is formulated in terms of a set of rate equations for the island sizes, combined with the time-dependent behavior of...

Recent research has shown that in referendum elections, the presence of interdependence within voter preferences can lead to election outcomes that are undesirable and even paradoxical. However, most of the examples leading to these undesirable outcomes involve contrived voting situations that...
