Reliable Energy-Efficient Routing Algorithm for Vehicle-Assisted Wireless Ad-Hoc Networks
We investigate the design of the optimal routing path in a moving vehicles
involved the internet of things (IoT). In our model, jammers exist that may
interfere with the information exchange between wireless nodes, leading to
worsened quality of service (QoS) in communications. In addition, the transmit
power of each battery-equipped node is constrained to save energy. We propose a
three-step optimal routing path algorithm for reliable and energy-efficient
communications. Moreover, results show that with the assistance of moving
vehicles, the total energy consumed can be reduced to a large extend. We also
study the impact on the optimal routing path design and energy consumption
which is caused by path loss, maximum transmit power constrain, QoS
requirement, etc.Comment: 6 pages, 5 figures, rejected by IEEE Globecom 2017,resubmit to IEEE

Bound on genuine multipartite correlations from the principle of information causality
Quantum mechanics is not the unique no-signaling theory which is endowed with
stronger-than-classical correlations, and there exists a broad class of
no-signaling theories allowing even stronger-than-quantum correlations. The
principle of information causality has been suggested to distinguish quantum
theory from these nonphysical theories, together with an elegant
information-theoretic proof of the quantum bound of two-particle correlations.
In this work, we extend this to genuine -particle correlations that cannot
be reduced to mixtures of states in which a smaller number of particles are
entangled. We first express Svetlichny's inequality in terms of multipartite
no-signaling boxes, then prove that the strongest genuine multipartite
correlations lead to the maximal violation of information causality. The
maximal genuine multipartite correlations under the constraint of information
causality is found to be equal to the quantum mechanical bound. This result
consolidates information causality as a physical principle defining the
possible correlations allowed by nature, and provides intriguing insights into
the limits of genuine multipartite correlations in quantum theory.Comment: 5 pages, 3 figures, published versio
Relativistic symmetry breaking in light kaonic nuclei
As the experimental data from kaonic atoms and scatterings imply
that the -nucleon interaction is strongly attractive at saturation
density, there is a possibility to form -nuclear bound states or kaonic
nuclei. In this work, we investigate the ground-state properties of the light
kaonic nuclei with the relativistic mean field theory. It is found that the
strong attraction between and nucleons reshapes the scalar and vector
meson fields, leading to the remarkable enhancement of the nuclear density in
the interior of light kaonic nuclei and the manifest shift of the
single-nucleon energy spectra and magic numbers therein. As a consequence, the
pseudospin symmetry is shown to be violated together with enlarged spin-orbit
splittings in these kaonic nuclei.Comment: 15 pages, 7 figure
