We study possible quantum states of two correlated electrons in a twodimensional periodic potential and find a metastable energy band of electron pairs between the two lowest singleelectron bands. These metastable states ...

The combined behavior of two or more individuals is subject to selection by the consequences of the environment, in the same way as individual operant behavior. Previous studies used an interdependence procedure to investigate ...

The coordinated multiple-point (CoMP) transmission technique recently has been considered as an efficient method to achieve energy-efficient cellular wireless communications and enhance cell-edge user performance. Conventional ...

Individuals with stroke often present functional impairment and gait alteration. Among different aspects, intralimb coordination of these individuals is one of the key points that should be considered before implementing ...

Temporal coordination of duets consists of nonrandom overlap, alternation or association between rhythms of acoustic elements. Since duet coordination presumably requires high attentiveness between signallers, the coalition ...

Observing high-energy gamma-rays from Active Galactic Nuclei (AGN) offers a unique potential to probe extremely tiny values of the intergalactic magnetic field (IGMF), a long standing question of astrophysics, astropa rticle ...

We analyze a recent discussion of one-dimensional quantum-mechanical models with a perturbation produced by a delta-function potential. We show that the authors failed to derive a correct transcendental equation for the ...
