篇章级共指关系是语言学和计算语言学的研究难点之一。本文在梳理共指理论研究与趋势的基础上,回顾共指语料库的构建与自动解析方法,指出共指语料的构建主要存在以下两个问题:共指关系的标注较为粗疏,也基本不考虑与句子语义结构本身的关系。本文在句子级语义标注体系(中文抽象语义表示)的基础上,设计篇章共指的标注体系,以“概念同一性”为基本原则,从词形的异同和概念的表述角度区分9种篇章共指关系,标注了500个篇章的共指信息。与已完整标注的52种句内语义关系相结合,构建出带有篇章共指信息的篇章抽象语义图库。该语料库选自CTB新闻语料,体裁涵盖经济、体育及生活类,规模为6237句,16万词例。该语料库的构建为篇章级语义分析提供了新框架与数据资源。

Indoxacarb and metaflumizone belong to a relatively new class of sodium channel blocker insecticides （SCBIs）. Due to intensive use of indoxacarb, field-evolved indoxacarb resistance has been reported in several lepidopteran pests, including the dia- mondback moth Plutella xylostella, a serious pest of cruciferous crops. In particular, the BY 12 population of P. xylostella, collected from Baiyun, Guangdong Province of China in 2012, was 750-fold more resistant to indoxacarb and 70-fold more resistant to metaflu- mizone compared with the susceptible Roth strain. Comparison of complementary DNA sequences encoding the sodium channel genes of Roth and BY12 revealed two point mu- tations （F1845Y and V1848I） in the sixth segment of domain IV of the PxNav protein in the BY population. Both mutations are located within a highly conserved sequence region that is predicted to be involved in the binding sites of local anesthetics and SCBIs based on mammalian sodium channels. A significant correlation was observed among 10 field-collected populations between the mutant allele （Y 1845 or I 1848） frequencies （1.7% to 52.5%） and resistance levels to both indoxacarb （34- to 870-fold） and metaflumizone （1- to 70-fold）. The two mutations were never found to co-exist in the same allele of PxNav, suggesting that they arose independently. This is the first time that sodium channel muta- tions have been associated with high levels of resistance to SCBIs. F 1845Y and V 1848I are molecular markers for resistance monitoring in the diamondback moth and possibly other insect pest species.

Helicoverpa armigera single nucleocapsid nucleopolyhedrovirns open reading frame 101 （ha101） is 762 nts in length and encodes a 254 amino acid peptide with predicted 29 kDa molecular weight. The homologues of ha101 were explored using BLASTP searching tool in the updated GenBank/EMBL and SWlSS-PROT databases. The results showed that the homologues of ha101 were present in all the completely sequenced lepidopteran nucleopolyhedrovirnses and granulovirnses, suggesting that ha101 might be a functional gene associated with their lepidopteran hosts. Sequence alignment of ha101 and its homologues revealed that 10 amino acids were completely conserved. RT-PCR analysis of ha101 manifested that the transcript of ha101 was first detected at 24 hpi and remained detectable at up to 122 hpi, suggesting that ha101 was transcribed during late stages of infection. Ha101 was expressed using Bac to Bac system in Tn5B-1-4 cells. The product of ha101 expressed in Tn5B-1-4 cells was approximately 29kDa, consistent with the predicted molecular weight, and the results were confirmed by western blot analysis. The subcellular localization indicated that ha101 was aggregated along nuclear envelope during the early stages of infection and spread out to the entire nucleus including virogenic stroma in late stages of infection, suggesting that ha101 may play a specific role in virion assembly process or virogenic stroma arrangement.

The existing three-parameter single-step time integration methods, such as the Generalized-a method, improve numerical dissipation by modifying equilibrium equation at time points, which cause them to lose accuracy due to the interpolation of load vectors. Moreover, these three-parameter methods do not present an available formulation applied to a general secondorder non linear differential equatio n. To solve these problems, this paper proposes an innovative three-parameter single-step method by introducing an additional variable into update equations. Although the present method is spectrally identical to the Generalized-cx method for undamped systems, it possesses higher accuracy since it strictly satisfies the equilibrium equation at time points, and can be readily used to solve nonlinear equations. By the analysis of accuracy, stability, numerical dissipation and dispersion, the optimal second-order implicit and explicit schemes are generated, which can maximize low-frequency accuracy when high-frequency dissipation is specified. To check the performance of the proposed method, several numerical experiments are conducted and the proposed method is compared with a few up-to-date methods.
