A representation basis for the quantum integrable spin chain associated with the su(3) algebra
An orthogonal basis of the Hilbert space for the quantum spin chain
associated with the su(3) algebra is introduced. Such kind of basis could be
treated as a nested generalization of separation of variables (SoV) basis for
high-rank quantum integrable models. It is found that all the monodromy-matrix
elements acting on a basis vector take simple forms. With the help of the
basis, we construct eigenstates of the su(3) inhomogeneous spin torus (the
trigonometric su(3) spin chain with antiperiodic boundary condition) from its
spectrum obtained via the off-diagonal Bethe Ansatz (ODBA). Based on small
sites (i.e. N=2) check, it is conjectured that the homogeneous limit of the
eigenstates exists, which gives rise to the corresponding eigenstates of the
homogenous model.Comment: 24 pages, no figure, published versio
On the Bethe states of the one-dimensional supersymmetric t-J model with generic open boundaries
By combining the algebraic Bethe ansatz and the off-diagonal Bethe ansatz, we
investigate the supersymmetric t-J model with generic open boundaries. The
eigenvalues of the transfer matrix are given in terms of an inhomogeneous T-Q
relation, and the corresponding eigenstates are expressed in terms of nested
Bethe states which have well-defined homogeneous limit. This exact solution
provides basis for further analyzing the thermodynamic properties and
correlation functions of the model.Comment: 17 pages, 2 tables, published versio
Semi-inclusive electroproduction of hidden-charm and double-charm hadronic molecules
The semi-inclusive electroproduction of exotic hadrons, including the
states, states, and hidden-charm baryon-antibaryon states, is
explored under the assumption that they are -wave hadronic molecules of a
pair of charmed hadrons. We employ the Monte Carlo event generator Pythia to
produce the hadron pairs and then bind them together to form hadronic
molecules. With the use of such production mechanism, the semi-inclusive
electroproduction rates are estimated at the order-of-magnitude level. Our
results indicate that a larger number of states and
molecules can be produced at the proposed
electron-ion colliders in China and in the US, EicC and US-EIC, respectively.
The results also suggest that the states and other hidden-charm
baryon-antibaryon states can be searched for at US-EIC. Besides, the potential
24 GeV upgrade of CEBAF at Jefferson Lab can play an important role in the
search of the hidden-charm tetraquark and pentaquark states due to its high
luminosity.Comment: 20 pages, 4 figure
A convenient basis for the Izergin-Korepin model
We propose a convenient orthogonal basis of the Hilbert space for the
Izergin-Korepin model (or the quantum spin chain associated with the
algebra). It is shown that the monodromy-matrix elements acting
on the basis take relatively simple forms (c.f. acting on the original basis ),
which is quite similar as that in the so-called F-basis for the quantum spin
chains associated with -type (super)algebras. As an application, we present
the recursive expressions of Bethe states in the basis for the Izergin-Korepin
model.Comment: 24 pages, no figure
Bethe ansatz solutions of the Ï„ 2-model with arbitrary boundary fields
The quantum -model with generic site-dependent inhomogeneity and
arbitrary boundary fields is studied via the off-diagonal Bethe Ansatz method.
The eigenvalues of the corresponding transfer matrix are given in terms of an
inhomogeneous T-Q relation, which is based on the operator product identities
among the fused transfer matrices and the asymptotic behavior of the transfer
matrices. Moreover, the associated Bethe Ansatz equations are also obtained.Comment: 26 pages, no figures, published versio
Complete genome sequence of a Megalocytivirus (family Iridoviridae) associated with turbot mortality in China
<p>Abstract</p> <p>Background</p> <p>Turbot reddish body iridovirus (TRBIV) causes serious systemic diseases with high mortality in the cultured turbot, <it>Scophthalmus maximus</it>. We here sequenced and analyzed the complete genome of TRBIV, which was identified in Shandong province, China.</p> <p>Results</p> <p>The genome of TRBIV is a linear double-stranded DNA of 110,104 base pairs, comprising 55% G + C. Total 115 open reading frames were identified, encoding polypeptides ranging from 40 to 1168 amino acids. Amino acid sequences analysis revealed that 39 of the 115 potential gene products of TRBIV show significant homology to other iridovirus proteins. Phylogenetic analysis of conserved genes indicated that TRBIV is closely related to infectious spleen and kidney necrosis virus (ISKNV), rock bream iridovirus (RBIV), orange-spotted grouper iridovirus (OSGIV), and large yellow croaker iridovirus (LYCIV). The results indicated that TRBIV belongs to the genus <it>Megalocytivirus </it>(family Iridoviridae).</p> <p>Conclusions</p> <p>The determination of the genome of TRBIV will provide useful information for comparative study of Megalocytivirus and developing strategies to control outbreaks of TRBIV-induced disease.</p
An optimal data service providing framework in cloud radio access network
Much work has been conducted to design effective and efficient algorithms for quality of service (QoS)-aware service computing in the past several years. The wireless mobile computing and cloud computing environments have brought many challenges to QoS-aware service providing. Mobile cloud computing (MCC) and cloud radio accessing networks (C-RANs) are the new paradigms arising in recent years. This work proposes a wireless data service providing framework in C-RAN aiming to provide data service in C-RAN by a more efficient way. The efficiency is measured by cost with time constraint. An abstract formal model is built on the proposed framework, and the corresponding optimal solution is deduced theoretically using queuing theory and convex optimization. The simulation results show that the proposed optimal strategy on the optimal solution works well and has a better performance than compared one
