Dance2MIDI: Dance-driven multi-instruments music generation
Dance-driven music generation aims to generate musical pieces conditioned on
dance videos. Previous works focus on monophonic or raw audio generation, while
the multiinstruments scenario is under-explored. The challenges of the
dance-driven multi-instruments music (MIDI) generation are two-fold: 1) no
publicly available multi-instruments MIDI and video paired dataset and 2) the
weak correlation between music and video. To tackle these challenges, we build
the first multi-instruments MIDI and dance paired dataset (D2MIDI). Based on
our proposed dataset, we introduce a multi-instruments MIDI generation
framework (Dance2MIDI) conditioned on dance video. Specifically, 1) to model
the correlation between music and dance, we encode the dance motion using the
GCN, and 2) to generate harmonious and coherent music, we employ Transformer to
decode the MIDI sequence. We evaluate the generated music of our framework
trained on D2MIDI dataset and demonstrate that our method outperforms existing
methods. The data and code are available on

The effects of large extra dimensions on associated production at linear colliders
In the framework of the large extra dimensions (LED) model, the effects of
LED on the processes \rrtth and \eetth at future linear colliders are
investigated in both polarized and unpolarized collision modes. The results
show that the virtual Kaluza-Klein (KK) graviton exchange can significantly
modify the standard model expectations for these processes with certain
polarizations of initial states. The process \rrtth with
allows the effective scale to be probed up to 7.8 and 8.6 TeV in
the unpolarized and , J=2 polarized collision
modes, respectively. For the \eetth process with , the upper
limits of to be observed can be 6.7 and 7.0 TeV in the unpolarized
and , , polarized collision modes,
respectively. We find the \rrtth channel in J=2 polarized photon collision mode
provides a possibility to improve the sensitivity to the graviton tower
exchange.Comment: To be appeard in Physical Review
QCD corrections to the R-parity violating processes at hadron colliders
We present the QCD corrections to the processes at
the Tevatron and the CERN large hadron collider(LHC). The numerical results
show that variation of K factor is in the range between and
at the Tevatron(LHC). We find that the QCD correction part from
the one-loop gluon-gluon fusion subprocess is remarkable at the LHC and should
be taken into account.Comment: 7 pages, 6 Postscript figures, to be appeared in Phy. Rev.
