In the field of information security,a gap exists in the study of coreference resolution of entities.A hybrid method is proposed to solve the problem of coreference resolution in information *** work consists of two parts:the first extracts all candidates(including noun phrases,pronouns,entities,and nested phrases)from a given document and classifies them;the second is coreference resolution of the selected *** the first part,a method combining rules with a deep learning model(Dictionary BiLSTM-Attention-CRF,or DBAC)is proposed to extract all candidates in the text and classify *** the DBAC model,the domain dictionary matching mechanism is introduced,and new features of words and their contexts are obtained according to the domain *** this way,full use can be made of the entities and entity-type information contained in the domain dictionary,which can help solve the recognition problem of both rare and long *** the second part,candidates are divided into pronoun candidates and noun phrase candidates according to the part of speech,and the coreference resolution of pronoun candidates is solved by making rules and coreference resolution of noun phrase candidates by machine ***,a dataset is created with which to evaluate our methods using information security *** experimental results show that the proposed model exhibits better performance than the other baseline models.

In this study,a series of CuCl_(2)-modified MnO_(x)-CeO_(x)nanorods were synthesized for the oxidation of Hg^(0).The addition of CuCl_(2)resulted in an enhancement in the catalyst’s Hg^(0)oxidation ability,and Hg^(0)oxidation efficiency reached>97%from 150 to 250°*** the MnO_(x)-CeO_(x)catalysts,Mn^(4+)played the role of the active species for Hg^(0)oxidization,but in the CuCl_(2)-doped catalysts Cl−also contributed to Hg^(0)oxidation,conferring the superior performance of these *** introduction of SO_(2) led to a decrease in the availability of Mn^(4+),and the Hg^(0)oxidation efficiency of MnO_(x)-CeO_(x)decreased from about 100%to about 78%.By contrast,CuCl_(2)-promoted samples maintained a Hg^(0)oxidation efficiency of about 100%during the SO_(2) deactivation cycle due to the high reactivity of Cl−.

Sanchuan ham is appreciated in Yunnan Province,China,for its characteristic flavor and taste,while the microbial community structure and biogenic amines content remain unclear during fermentation *** this study,we explored the physicochemical property,biogenic amines concentration and microbial diversity of external and internal Sanchuan ham by high-throughput sequencing during the processing of Sanchuan *** showed that the nitrite remained at a stable level of 0.15 mg/kg which was significantly lower than the national health standard safety level of 20 mg/*** addition,compared with fresh hams,the content of total free amino acids in ripe Sanchuan ham has grown 14 folds;sour and bitter were the main tastes of Sanchuan ***,the concentration of cadaverine was the highest of all biogenic amines during the entire fermentation *** the bacterial phyla level,Firmicutes and Actinobacteria were the two main phyla,while at the genus level,Staphylococcus was a significant strain throughout the whole ***,the dry stage has a great impact on the succession change of microbial community ***,the change trends and composition of bacteria in the interior have slight discrepancies with those of the exterior of Sanchuan ham.

This study demonstrated the impacts of the synthesis methods on the textural structures,chemical properties,and Hg^(0)capture capability of the MnO_(x)*** with the samples synthesized using the precipitation(PR)and hydrothermal(HT)methods,the adsorbent prepared via the sol-gel(SG)technique gave the best *** 150℃,ca.90%Hg^(0)removal efficiency was reached after 7.5 h for MnO_(x)prepared by the SG method,ca.40%higher than that of the other two *** specific surface area of the adsorbent synthesized via the SG technique(23 m^(2)/g)was almost double that of the adsorbent prepared by the HT method(12 m^(2)/g)and three times that of the one prepared by the PR method(7 m^(2)/g).The presence of plentiful acid sites from the SG method facilitated the physisorption of Hg^(0),making more Hg^(0)available to be oxidized to HgO by the redox sites and thus giving the adsorbent prepared by the SG method the highest Hg^(0)removal *** strong oxidative ability accelerated the oxidation of the physically adsorbed Hg^(0)to HgO,which explained the higher Hg^(0)removal efficiency of the sample prepared using the HT method than that of the one synthesized by the PR *** the whole Hg^(0)removal cycles,chemisorption dominated,with the initial adsorption stage and the external mass-transfer process playing important roles.

Plant natural products as effective options for inhibiting foodborne pathogens: A comprehensive review of their activities， mechanisms， and applications in food preservation

2013年教育技术与管理科学国际会议

作者： hu yongjin School of Foreign Studies Suzhou University

The research aims at investigating the effects of different modalities and combinations of them on English Listening Teaching, exploring the factors influencing the pattern of multimodality with optimal function and setting practical example to improve the quality of English Listening Teaching. The result shows that reasonable utilization of the combination of multimodalities can improve learners’ listening competence;the choice of the combination of multimodalities depends on the context of situation;visual information can give play to positive function providing that it is complementary to auditory information;In addition, L2 subtitling is more beneficial than L1 because it causes less lexical interference.

In order to ensure food safety， controlling foodborne pathogen contamination is of utmost importance. Growing apprehensions regarding the safety of synthetic antimicrobials， due to their adverse health effects， have prompted a search for alternative options. Plant natural products (PNPs) with antimicrobial activity are being explored as a viable alternative. Among the various antimicrobial natural products studied， plant essential oils， plant flavonoids， plant polyphenols， plant polysaccharides， and plant antimicrobial peptides have been identified as potential candidates. PNPs demonstrate a diverse array of antimicrobial mechanisms， encompassing cell wall and membrane damage， interference with genetic replication， disruption of energy metabolism， and induction of oxidative stress at the single-cell level， as well as inhibition of biofilm formation and quorum sensing at the population level. Certain PNPs have been harnessed as natural antimicrobial agents for the food preservation. The utilization of encapsulation technology proves to be an effective strategy in protecting PNPs， thereby ensuring good antimicrobial efficacy， enhanced dispersibility， and controlled release within food products. The utilization of nanoemulsions， nanoliposomes， edible packaging， electrospun nanofibers， and microcapsules formed by encapsulation has enriched the ways in which PNPs can be applied in food preservation. Although PNPs have great potential in food preservation， their widespread application in the food industry is currently constrained by factors such as production costs， safety concerns， and legal considerations. Chemical synthesis and biosynthesis pathways offer viable strategies for reducing the cost of producing PNPs， and ongoing efforts to assess safety and improve regulatory frameworks are likely to facilitate the broader adoption of PNPs in food preservation practices. This article provides an overview of the main types of PNPs with antimicrobial activity and their prope

准确地提取林地分布信息是林地管理、保护和可持续利用的关键步骤。针对现有林地提取方法精度较低且边缘不够精细的问题,提出一种联合上下文感知与边界约束(CABC-Net)的遥感影像林地提取方法。首先,设计上下文感知(CA)模块,用于探索空间像素信息之间的联系,并通过层间特征传递提取足够的全局上下文信息,以降低上下文差异和复杂背景对检测结果的干扰。其次,为进一步优化边缘细节,提出边界约束(BC)模块,将边界特征与深层特征结合作为模型的辅助特征,缩小定位林地边界的波动范围,校准不确定性区域以提高边界判别能力。最后,为验证方法的有效性,建立一个新的数据集并开展案例试验分析。结果表明,该方法交并比提高0.55%~9.45%,像素准确率提高0.19%~7.53%,本方法在面对复杂场景时具有更好的边界完整度,能够更好地用于林地提取。
