High-order rogue waves of a long wave-short wave model
The long wave-short wave model describes the interaction between the long
wave and the short wave. Exact higher-order rational solution expressed by
determinants is calculated via the Hirota's bilinear method and the KP
hierarchy reduction. It is found that the fundamental rogue wave for the short
wave can be classified into three different patterns: bright, intermediate and
dark ones, whereas the rogue wave for the long wave is always bright type. The
higher-order rogue waves correspond to the superposition of fundamental rogue
waves. The modulation instability analysis show that the condition of the
baseband modulation instability where an unstable continuous-wave background
corresponds to perturbations with infinitesimally small frequencies, coincides
with the condition for the existence of rogue-wave solutions.Comment: 14 pages, 5 figure
Szu-Feng Chen, Assistant Professor, Department of Theatre and Dance, travels to Singapore
Professor Szu-Feng Chen was invited by The Theatre Practice (TTP) in Singapore to create set and costume design for Lao Jiu: The Musical, its feature musical production for the Singapore Kuo Pao Kun Festival.I was invited by The Theatre Practice (TTP) in Singapore to create set and costume design for its feature musical production for Singapore Kuo Pao Kun Festival. Lao Jiu: The Musical, is a musical version of Kuo’s signature play. It was opened in July 2012 in memory of ten years of Kuo Pao Kun’s passing. Kuo Pao Kun was the pioneer and art educator of Singaporean theatre—awarded the National Culture Medallion in 1989, the Culture Award in 1992, Asean Cultural Award in 1993and the Excellence for Singapore Award in 2002. The festival is hosted by The Theatre Practice and supported by Singapore National Arts Council in honor of Kuo’s contribution to the Singapore performing arts
Rare Decays
Studies of rare decays play an important role in the search of physics beyond
the standard model. New particles may participate in the loop processes and can
be probed by seeing any deviations from the standard model predictions. The
very rare decay has been observed with the data collected by
CMS and LHCb experiments. The signal seen by the ATLAS experiment is less
significant but is compatible with the predictions. The measurement itself
provides stringent constraints to new physics models. The first effective
lifetime measurement with candidates has been carried out by
the LHCb experiment. More data are still required to observe the
decays. The decay also proceeds through
a flavour changing neutral current process, and is sensitive to the new
physics. Extended measurements are carried out for decays.
Most of the classical physics parameters are found to be consistent with the
predictions, but tensions do emerge in some of the observables. More data will
help to clarify these potential deviations.Comment: 7 pages, for LHCP 2017 conferenc
