We propose a power-law decay model with autocorrelation for posting data to
social networking services concerning particular events such as national
holidays or major sport events. In these kinds of events we observe people's
interest both before ...

We discussed subspaces of the N=1 supersymmetric sine-Gordon model with
Dirichlet boundaries through light-cone lattice regularization. In this paper,
we showed, unlike the periodic boundary case, both of Neveu-Schwarz (NS) and
Ramond (R) sectors ...

It is known that the Markov matrix of the asymmetric simple exclusion process
(ASEP) is invariant under the Uq(sl2) algebra. This is the result of the fact
that the Markov matrix of the ASEP coincides with the generator of the
Temperley-Lieb (TL) ...

Revising the derivation of the previous papers, for the integrable spin-Tex
XXZ chain we express any form factor in terms of a single sum over scalar
products of the spin-1/2 XXZ chain. With the revised method we express the
spin-Tex XXZ correlati...

We discuss some fundamental properties of the XXZ spin chain, which are
important in the algebraic Bethe-ansatz derivation for the multiple-integral
representations of the spin-s XXZ correlation function with an arbitrary
product of elementary mat...
