InfoVis experience enhancement through mediated interaction
Information visualization is an experience in which both the aesthetic representations and interaction are part. Such an experience can be augmented through close consideration of its major components. Interaction is crucial to the experience, yet it has seldom been adequately explored in the field. We claim that direct mediated interaction can augment such an experience. This paper discusses the reasons behind such a claim and proposes a mediated interactive manipulation scheme based on the notion of directness. It also describes the ways in which such a claim will be validated. The Literature Knowledge Domain (LKD) is used as the concrete domain around which the discussions will be held
Photon-Mediated Interaction between Two Distant Atoms
We study the photonic interactions between two distant atoms which are
coupled by an optical element (a lens or an optical fiber) focussing part of
their emitted radiation onto each other. Two regimes are distinguished
depending on the ratio between the radiative lifetime of the atomic excited
state and the propagation time of a photon between the two atoms. In the two
regimes, well below saturation the dynamics exhibit either typical features of
a bad resonator, where the atoms act as the mirrors, or typical characteristics
of dipole-dipole interaction. We study the coherence properties of the emitted
light and show that it carries signatures of the multiple scattering processes
between the atoms. The model predictions are compared with the experimental
results in J. Eschner {\it et al.}, Nature {\bf 413}, 495 (2001).Comment: 18 pages, 15 figure
Photon mediated interaction between distant quantum dot circuits
Engineering the interaction between light and matter is an important goal in
the emerging field of quantum opto-electronics. Thanks to the use of cavity
quantum electrodynamics architectures, one can envision a fully hybrid
multiplexing of quantum conductors. Here, we use such an architecture to couple
two quantum dot circuits . Our quantum dots are separated by 200 times their
own size, with no direct tunnel and electrostatic couplings between them. We
demonstrate their interaction, mediated by the cavity photons. This could be
used to scale up quantum bit architectures based on quantum dot circuits or
simulate on-chip phonon-mediated interactions between strongly correlated
electrons
Dimensional Affect and Expression in Natural and Mediated Interaction
There is a perceived controversy as to whether the cognitive representation
of affect is better modelled using a dimensional or categorical theory. This
paper first suggests that these views are, in fact, compatible. The paper then
discusses this theme and related issues in reference to a commonly stated
application domain of research on human affect and expression: human computer
interaction (HCI). The novel suggestion here is that a more realistic framing
of studies of human affect in expression with reference to HCI and,
particularly HCHI (Human-Computer-Human Interaction) entails some
re-formulation of the approach to the basic phenomena themselves. This theme is
illustrated with several examples from several recent research projects.Comment: Invited article presented at the 23rd Annual Meeting of the

On the ion-mediated interaction between protein and DNA
The mechanism allowing a protein to search of a target sequence on DNA is
currently described as an intermittent process composed of 3D diffusion in bulk
and 1D diffusion along the DNA molecule. Due to the relevant charge of protein
and DNA, electrostatic interaction should play a crucial role during this
search. In this paper, we explicitly derive the mean field theory allowing for
a description of the protein-DNA electrostatics in solution. This approach
leads to a unified model of the search process, where 1D and 3D diffusion
appear as a natural consequence of the diffusion on an extended interaction
energy profile.Comment: Proceedings of the 29th ICMP Conference, Tianjin, China (2013
Internal Consistency and Reliability of the Networked Minds\ud Measure of Social Presence
This study sought to develop and test a measure\ud
of social presence. Based on review of current\ud
definitions and measures, a synthesis of the\ud
theoretical construct that meets the criteria and\ud
dimensions [1] is proposed for a broad successful\ud
measure of social presence. An experiment was\ud
conducted to test the internal consistency and\ud
criterion validity of the measures as determined by\ud
theory, specifically the ability of the measure to\ud
distinguish levels of social presence that almost all\ud
theories suggest exist between (1) face-to-face\ud
interaction and mediated interaction, and (2)\ud
different levels of mediated interaction
High fidelity quantum gates of trapped ions mediated by a dissipative bus mode
We describe the optimal realization of entangling quantum gates for trapped
ions mediated by a dissipative bus mode. With suitably shaped control pulses
one can substantially decrease ion-phonon entanglement while maintaining the
mediated interaction
