Novel Compact Three-Way Filtering Power Divider Using Net-Type Resonators
In this paper, we present a novel compact three-way power divider with bandpass responses. The proposed power divider utilizes folded net-type resonators to realize dual functions of filtering and power splitting as well as compact size. Equal power ratio with low magnitude imbalance is achieved due to the highly symmetric structure. For demonstration, an experimental three way filtering power divider is implemented. Good filtering and power division characteristics are observed in the measured results of the circuit. The area of the circuits is 14.5 mm x 21.9 mm or 0.16 λg x 0.24 λg, where the λg is the guide wavelength of the center frequency at 2.1 GHz
Anisotropic distributions in a multi-phase transport model
With A Multi-Phase Transport (AMPT) model we investigate the relation between
the magnitude, fluctuations and correlations of the initial state spatial
anisotropy and the final state anisotropic flow coefficients
in Au+Au collisions at 200 GeV. It is found
that the relative eccentricity fluctuations in AMPT account for the observed
elliptic flow fluctuations, in agreement with measurements of the STAR
collaboration. In addition, the studies based on 2- and multi-particle
correlations and event-by-event distributions of the anisotropies suggest that
the Elliptic-Power function is a promising candidate of the underlying
probability density function of the event-by-event distributions of
as well as . Furthermore, the correlations between
different order symmetry planes and harmonics in the initial coordinate space
and final state momentum space are presented. Non-zero values of these
correlations have been observed. The comparison between our calculations and
data will, in the future, shed new insight into the nature of the fluctuations
of the Quark-Gluon Plasma produced in heavy ion collisions.Comment: 10 pages, 8 figures, accepted by PR
On Functional Decomposition of Multivariate Polynomials with Differentiation and Homogenization
In this paper, we give a theoretical analysis for the algorithms to compute
functional decomposition for multivariate polynomials based on differentiation
and homogenization which are proposed by Ye, Dai, Lam (1999) and Faugere,
Perret (2006, 2008, 2009). We show that a degree proper functional
decomposition for a set of randomly decomposable quartic homogenous polynomials
can be computed using the algorithm with high probability. This solves a
conjecture proposed by Ye, Dai, and Lam (1999). We also propose a conjecture
such that the decomposition for a set of polynomials can be computed from that
of its homogenization with high probability. Finally, we prove that the right
decomposition factors for a set of polynomials can be computed from its right
decomposition factor space. Combining these results together, we prove that the
algorithm can compute a degree proper decomposition for a set of randomly
decomposable quartic polynomials with probability one when the base field is of
characteristic zero, and with probability close to one when the base field is a
finite field with sufficiently large number under the assumption that the
conjeture is correct
Neighborhood Matching Network for Entity Alignment
Structural heterogeneity between knowledge graphs is an outstanding challenge
for entity alignment. This paper presents Neighborhood Matching Network (NMN),
a novel entity alignment framework for tackling the structural heterogeneity
challenge. NMN estimates the similarities between entities to capture both the
topological structure and the neighborhood difference. It provides two
innovative components for better learning representations for entity alignment.
It first uses a novel graph sampling method to distill a discriminative
neighborhood for each entity. It then adopts a cross-graph neighborhood
matching module to jointly encode the neighborhood difference for a given
entity pair. Such strategies allow NMN to effectively construct
matching-oriented entity representations while ignoring noisy neighbors that
have a negative impact on the alignment task. Extensive experiments performed
on three entity alignment datasets show that NMN can well estimate the
neighborhood similarity in more tough cases and significantly outperforms 12
previous state-of-the-art methods.Comment: 11 pages, accepted by ACL 202
