It can be achieved either by channel reciprocity characteristics in time-division-duplex (TDD) mode or by feedback in frequency-division-duplex (FDD) mode.
The semi-inductor accounts for electromagnetic eddy-currents, the 'skin effect' of a conductor (Vanderkooy, 1989), while the gyrator (McMillan, 1946; Tellegen, 1948) accounts for the anti-reciprocity characteristic [Lenz's law (Hunt, 1954, p. 113)].
This unavoidable reciprocity is characteristic for the sense of touch.
This rests on recurrent message-passing between these systems that leads to self-organized activation patterns with a characteristic reciprocity or 'give-and-take' among levels.
Authority moderated associations between reciprocity and several characteristics of closeness such that reciprocity was positively linked to interdependence, daily social interaction, and weekly activity diversity, but only in relationships characterized by low levels of authority.
Lorentz reciprocity is a fundamental characteristic of the vast majority of electronic and photonic structures.
The main focus is on the connections between certain symmetry properties (such as reality and reciprocity) of the external characteristics of a s/s system and the respective symmetry of the evolution of the inner state of the system.
Honesty, fidelity, trustworthiness, kindness to others, and reciprocity are probably primeval characteristics that helped our ancestors survive.
I would be remiss not to point out that although it entails high levels of prosocial behavior characteristic of gratitude, reciprocity itself doesn't necessarily have to involve gratitude.
Previous work has shown reciprocity to be a dominant characteristic of several online social networks such as Twitter [28], Flickr [41], and Yahoo 360 [42].
Following the identification approach proposed to solve this problem and which is based on the reciprocity theorem, the impact location characteristics were determined by using particle swarm optimization algorithm.
