A unified approach to hadron phenomenology at zero and finite temperatures in a hard-wall AdS/QCD model
We propose a unified approach to study meson, nucleon and -baryon
properties at zero and finite temperatures in the context of hard-wall AdS/QCD
model. We first combine some previous works dealing with mesons and baryons
separately, and introduce a new parameter~ so that the model could give a
universal description of spectrum and couplings of both sectors in a
self-consistent way. All observables calculated numerically show reasonable
agreement with experimental data. We then study these observables at nonzero
temperature by modifying the AdS space-time into AdS-Schwartzchild space-time.
Numerically solving the model, we find an interesting temperature dependence of
the spectrum and the couplings. We also make a prediction on the finite
temperature decay width of some nucleon and excited states.Comment: 19 latex pages, 5 figures, final version for publicatio
A Unified Approach to Holomorphic Anomaly Equations and Quantum Spectral Curves
We present a unified approach to holomorphic anomaly equations and some
well-known quantum spectral curves. We develop a formalism of abstract quantum
field theory based on the diagrammatics of the Deligne-Mumford moduli spaces
and derive a quadratic recursion relation for
the abstract free energies in terms of the edge-cutting operators. This
abstract quantum field theory can be realized by various choices of a sequence
of holomorphic functions or formal power series and suitable propagators, and
the realized quantum field theory can be represented by formal Gaussian
integrals. Various applications are given.Comment: A section is adde
AP17-OLR Challenge: Data, Plan, and Baseline
We present the data profile and the evaluation plan of the second oriental
language recognition (OLR) challenge AP17-OLR. Compared to the event last year
(AP16-OLR), the new challenge involves more languages and focuses more on short
utterances. The data is offered by SpeechOcean and the NSFC M2ASR project. Two
types of baselines are constructed to assist the participants, one is based on
the i-vector model and the other is based on various neural networks. We report
the baseline results evaluated with various metrics defined by the AP17-OLR
evaluation plan and demonstrate that the combined database is a reasonable data
resource for multilingual research. All the data is free for participants, and
the Kaldi recipes for the baselines have been published online.Comment: Submitted to APSIPA ASC 2017. arXiv admin note: text overlap with
