A narrow resonance peak was observed at 1.54±0.01 GeV/c as an exotic baryon with strangeness S = +1 in the γ + n → K +K− + n reaction on C. The new state have a width smaller than 0.025 GeV/c and a Gaussian significance of 4.6σ. It can not be interpreted as three quark state and is consistent with the lightest member of an antidecuplet of baryons predicted by the chiral soliton model.

The three flavor version of the Nambu–Jona–Lasinio chiral soliton model for baryons is employed to calculate the twist–2 contribution to the polarized nucleon structure function g 1 (x). In particular the role of the strange quark degree of freedom as a collective excitation of the chiral soliton is investigated in the context of flavor symmetry breaking. The model prediction for g 1 (x) refers...

We find a new type of optical vector soliton that originates from trapping of a dipole mode by the soliton-induced waveguides. These solitons, which appear as a consequence of the vector nature of the two-component system, are more stable than the previously found optical vortex solitons and represent a new type of extremely robust nonlinear vector structure.

We study improved degree distribution for Luby Transform (LT) codes which exhibits improved bit error rate performance particularly in low overhead regions. We construct the degree distribution by modifying Robust Soliton distribution. The performance of our proposed LT codes is evaluated and compared to the conventional LT codes via And-Or tree analysis. Then we propose a transmission scheme b...

: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...

We quantify the notion of a dense soliton gas by establishing an upper bound for the integrated density of states of the quantum-mechanical Schrödinger operator associated with the Korteweg-de Vries soliton gas dynamics. As a by-product of our derivation, we find the speed of sound in the soliton gas with Gaussian spectral distribution function.

An overview of recent results in the field of vortex (spinning) solitons and soliton complexes composed of several fundamental (nonspinning) solitons in twoand three-dimensional optical media with competing nonlinearities is presented. It is concluded that multidimensional solitons with intrinsic topological charge are stable provided that their internal size and power (energy) are large enough...

The soliton physics for the propagation of waves is represented by a stochastic model in which the particles of the wave can jump ahead according to some probability distribution. We demonstrate the presence of a steady state (stationary distribution) for the wavelength. It is shown that the stationary distribution is a convolution of geometric random variables. Approximations to the stationary...

the paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. in real-world cases, demands and transshipment costs change over the period of the time. this may lead to large cost deviation in total cost. scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...
