We provide a review of our recent 100-Gb/s, high spectral efficiency （SE） ex.eriment targeting transoceanic and regional undersea transmission distances. We demonstrated that simple pre-filtering at the transmitter together with a max.mum a posteriori probability （MAP） detection algorithm can significantly improve SE. We transmitted 96×100-Gb/s pre-filtered polarization division multiplex.d return-to-zero quadrature phase shift keyed （PDM-RZ-QPSK） channels with 300% SE over 10608 km using 52-km spans of 150-μm 2 fiber and simple single-stage erbium-doped fiber amplifiers （EDFAs）. We also achieved 400% SE over 4368 km using similar techniques.

We calculate the information entropy of avalanche size distribution in the Bak-Sneppen evolution model. It is found that the information entropy increases as the evolution moves forward. Specifically, we establish relation between the information entropy and the self-organized threshold f. The evolution of the information entropy near the critical point yields an ex.onent, entropy index.E = (7 - 1)/ D(g), related to the information entropy, is suggested to represent the distance between the current state and the critical state.

Randomly amplified polymorphic DNA (RAPD) technique was applied to assess the genetic variations and phylogenetic relationships in genetic differentiation within 4 Chromium-treatment Leersia hex.ndra. The fresh leaves of Leersia hex.ndra cultivated on the condition of chrome pollution and ex.genous organic acids were used as ex.erimental material. The genomic DNA of Leersia hex.ndra was ex.racted by using CTAB method. The results showed that different samples of Leersia hex.ndra ex.ibited DNA polymorphism when using the random primer S43, S51and S55 as the primers in the RAPD reaction. One specific DNA band about 1000 bp was found in the sample which treated with 10 mmol/L concentration EDTA when used the S43 primer to RAPD. The obvious differences between different EDTA-treatment levels suggest that EDTA has certain effects on enrichment to heavy metals of Leersia hex.ndra, it will be more favored to Leersia hex.ndra accumulation of chromium when EDTA concentration increased.

Lattice QCD calculations have predicted a transition from quark-gluon plasma (QGP) to hadronic matter at a high temperature or density. The recent results form the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) have demonstrated that a hot dense new matter with strong collective motion which can not be described with hadronic degrees of freedom was created at RHIC.

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.

In this paper, a distributed adaptive dynamic programming(ADP) framework based on value iteration is proposed for multi-player differential games. In the game setting,players have no access to the information of others' system parameters or control laws. Each player adopts an on-policy value iteration algorithm as the basic learning framework. To deal with the incomplete information structure, players collect a period of system trajectory data to compensate for the lack of information. The policy updating step is implemented by a nonlinear optimization problem aiming to search for the prox.mal admissible policy. Theoretical analysis shows that by adopting prox.mal policy searching rules, the approx.mated policies can converge to a neighborhood of equilibrium policies. The efficacy of our method is illustrated by three ex.mples, which also demonstrate that the proposed method can accelerate the learning process compared with the centralized learning framework.

＜正＞We discuss the problem of scheduling n jobs on a single machine which is subject to stochastic breakdowns to minimize the weighted ex.ectation of quadratic deviation with random processing times. Deterministic equivalent of the stochastic scheduling problem is obtained when point process N（t） related to the machine uptime distribution is a generalized Poisson process. A sufficient condition under which an optimal sequence of the stochastic scheduling problem is V-shaped in terms of μi/Wi,i∈n={1,2…,n} has been derived.
