In this paper, issues of speeding.up Recurrent neural network lang.ag. model(RNNLM) in the testing.phase are explored so that RNNLMs can be used to re-rank a larg. n-best list in real-time systems which could obtain better performance. A new n-best list rescoring.framework, Prefix tree based n-best list re-scoring.PTNR), is proposed to hundred percent eliminate the repeated computations which makes n-best list re-scoring.ineffective. At the same time, the bunch mode technique,widely-used in speeding.up the training.of Feed-forward neural network lang.ag. model(FF-NNLM), is combined with PTNR and the speed is further improved. Experimental results show that our approach is much faster than basic n-best list re-scoring. take 1000-best as an example, our approach is almost 11 times faster than the basic n-best list re-scoring.

Titanium dioxide nanoparticles （TiO2 NPs） are among.the most widely manufactured nanomaterials on a g.obal scale. However, prudent and vig.lant surveillance, incumbent upon the scientific community with the advent of new technolog.es, has revealed potentially undesirable effects of TiO2 NPs on biolog.cal systems and the natural environment during.their application and discharg.. Such effects are likely best evaluated by first assessing.the fate of the TiO2 NPs in natural environments. In this study, the effects of terrestrial humic acid （HA） and tannic acid （ta）, two major members of the collective： dissolved org.nic matter （DOM）, on the cytotoxicity of TiO2 NPs to Escherichia coli were investig.ted in the presence and absence of natural sunlig.t. Qualitative （transmission electron microscopy （TEM）） and quantitative （LCso） analyses were employed in this study. In addition, the production of reactive oxyg.n species （ROS） in the form of .OH was further assessed-as HA or ta.increased the production of ROS decreased. The inhibition of bacterial viability in the lig.t treatment g.oups, with respective treatment org.nics at concentrations of 10 ppm, was less in ta than in terrestrial HA. SAS was used to analyze the treatment effect of individual factors of lig.t irradiation, DOM, and concentration of TiO2 NPs.

We study radiative decays of T to lig.t quark jets in nonrelativistic QCD by ta.ing.both the color sing.et and color octet b^-b operators into consideration. The cut for quark jet energ. and cut for the ang.e between two quark jets are introduced. The sensitivity to the soft and collinear sing.larities in the loop integ.als are g.eatly reduced by these cuts. With the jet energ. cut of about 1 g.V, and the jet ang.e cut of about 36°, the branching.ratio for γ→ rq^- is found to be 8.2 × 10^-4 from color sing.et contributions. The color octet contributions could be much larg.r than that of color sing.et, depending.on the estimate of the color octet matrix elements. This process may provide a new test for the color octet mechanism in nonrelativistic QCD.
