A Corpus-based Study on "However" in Chinese Learners' Writing

The use of "however" by Chinese learners' writing is studied through a comparison of its use in CLEC and in BROWN and found that "however" is overused in the front of a sentence,underused in the middle of a sentence and misused as a disjunctive conjunction,as is followed by the analysis of three attributable factors,i.e.the writing style,confusion with "but" and negative L1 transfer.

Corpus-Based Approach on Stylistic Features in Mark Twain's Novel——Taking The Man That Corrupted Hadlyburg as One Example

Mark Twain, the founder of critical realism in the United States, is a famous master of short story in the world. He experienced the process from American liberal capitalism to imperialism. The writing style is also changed from funny to pessimistic. His works have been translated into many languages and highly praised by readers and media all over the word. One of his novels, the classic novel The Man that Corrupted Hedlyburg by Mark Twain. Its plot is designable and the description of psychology is profound. It is known as the treasure of Mark Twain's works. Various literary critical analyses on this story have been made from different perspectives; however, there is no complete and thorough analysis on it from the perspective of corpus-based stylistics.In order to achieve this target, an observed corpus and a reference corpus are both built. The observed corpus is the electronic text of The Man while the reference corpus consists of four electronic texts of Mark Twain. In this research, three softwares, AntConc,WordSmith Tools and UAM CorpusTool, are applied. This thesis conducts a systemic stylistics analysis to the corpus-based approach of The Man That Corrupted Hadlyburg at three levels, lexical level, syntactic level, discourse level. At last it summarizes theprevious study and points out the main purpose of the thesis. And in the meantime, the limitation exists in the thesis and the suggestions for the subsequent exploration are also concluded. It is hoped that this study will help English learners to better understand and appreciate the meaning and aesthetic value of the text.

A Review on Sources,Extractions and Analysis Methods of a Sustainable Biomaterial:Tannins

Condensed and hydrolysable tannins are non-toxic natural polyphenols that are a commercial commodity industrialized for tanning hides to obtain leather and for a growing number of other industrial applications mainly to substitute petroleum-based products.They are a definite class of sustainable materials of the forestry industry.They have been in operation for hundreds of years to manufacture leather and now for a growing number of applications in a variety of other industries,such as wood adhesives,metal coating,pharmaceutical/medical applications and several others.This review presents the main sources,either already or potentially commercial of this forestry by-materials,their industrial and laboratory extraction systems,their systems of analysis with their advantages and drawbacks,be these methods so simple to even appear primitive but nonetheless of proven effectiveness,or very modern and instrumental.It constitutes a basic but essential summary of what is necessary to know of these sustainable materials.In doing so,the review highlights some of the main challenges that remain to be addressed to deliver the quality and economics of tannin supply necessary to fulfill the industrial production requirements for some materials-based uses.

The Bibliometric Studies on China’s Corpus-Based Interpreting Studies

Shlesinger (1998) first proposed that corpus-based interpreting studies(CIS) should be regarded as an offshoot of corpus-based translation studies (CTS).In China, owing to the development and compilation of interpreting corpora, CIShas gained momentum since 2007. To review the past achievements in this regard,the present paper first summarizes four readily compiled interpreting corpora. Then,based on the China National Knowledge Infrastructure (CKNI), it conducts thestatistics mainly on relevant published papers in Chinese Social Science and Index(CSSCI) journals. Next, it pinpoints a bibliometric analysis on the data by taking intoaccount three parameters, namely, H index, reference citation and their distribution.Then, it makes a detailed review and comments on the background of CIS and itsparadigm, theoretical interpretation of CIS and the research areas of CIS, standardsof developing interpreting corpora and solutions to difficulties in compilation ofinterpreting corpora, research orientations including topics and objects. At present,although CIS have attained preliminary findings and conclusions, it has mainly reliedon the theoretical and analytical frameworks of Systemic Functional Grammar andits utility in CIS, given the fact that it has introduced few interdisciplinary studies.As a result, CIS do not take full advantage of the paradigm of corpus linguistics norexplore into such research topics as features of interpretation, interpreters’ identitiesand interpreting styles. Finally, regarding future studies, the paper proposes that CISshould foreground the relevance of improving the mechanism of interpreting corpuscompilation in order to gain ground in new research methods and perspectives.

A Corpus-Based Comparative Study of Translation Universals in Two English Translations of Li Sao

The present study chooses Li Sao,one of the representatives of traditional Chinese Chu culture,as the research subject.Through establishing two small monolingual corpora,a comparative analysis of Yang Xianyi’s translation and David Hawkes’translation was made from the perspective of translation universals on three levels,namely lexical level,syntactic level and textual level.The results show that two translations both reflect the translation universals to some extent,but Hawkes’translation is more consistent with the translation universals in comparison with Yang Xianyi’s on the whole.

Drilling-based measuring method for the c-φ parameter of rock and its field application

The technology of drilling tests makes it possible to obtain the strength parameter of rock accurately in situ. In this paper, a new rock cutting analysis model that considers the influence of the rock crushing zone(RCZ) is built. The formula for an ultimate cutting force is established based on the limit equilibrium principle. The relationship between digital drilling parameters(DDP) and the c-φ parameter(DDP-cφ formula, where c refers to the cohesion and φ refers to the internal friction angle) is derived, and the response of drilling parameters and cutting ratio to the strength parameters is analyzed. The drillingbased measuring method for the c-φ parameter of rock is constructed. The laboratory verification test is then completed, and the difference in results between the drilling test and the compression test is less than 6%. On this basis, in-situ rock drilling tests in a traffic tunnel and a coal mine roadway are carried out, and the strength parameters of the surrounding rock are effectively tested. The average difference ratio of the results is less than 11%, which verifies the effectiveness of the proposed method for obtaining the strength parameters based on digital drilling. This study provides methodological support for field testing of rock strength parameters.

A Corpus-Based Contrastive Critical Genre Analysis of Universities’Introductory Discourses

Educational discourses,or to be more specific,universities’introductory discourses have not been studied from the contrastive perspective using critical genre analysis theories.This study uses Fairclough’s framework of discourse analysis to take a corpus-based contrastive study between the Chinese and global universities’introductory discourses from three aspects.Firstly,the textual dimension will be explored using the corpus-based approach.Secondly,it studies from the discursive dimension from intertextuality and interdiscursivity.Finally,the social cultural perspective study will be given about the corresponding social cultural interpretation on the differences between Chinese and global universities’introduction discourses.

A comparison study on structure-function relationship of polysaccharides obtained from sea buckthorn berries using different methods:antioxidant and bile acid-binding capacity

In this study,the structural characters,antioxidant activities and bile acid-binding ability of sea buckthorn polysaccharides(HRPs)obtained by the commonly used hot water(HRP-W),pressurized hot water(HRP-H),ultrasonic(HRP-U),acid(HRP-C)and alkali(HRP-A)assisted extraction methods were investigated.The results demonstrated that extraction methods had significant effects on extraction yield,monosaccharide composition,molecular weight,particle size,triple-helical structure,and surface morphology of HRPs except for the major linkage bands.Thermogravimetric analysis showed that HRP-U with filamentous reticular microstructure exhibited better thermal stability.The HRP-A with the lowest molecular weight and highest arabinose content possessed the best antioxidant activities.Moreover,the rheological analysis indicated that HRPs with higher galacturonic acid content and molecular weight showed higher viscosity and stronger crosslinking network(HRP-C,HRP-W and HRP-U),which exhibited stronger bile acid binding capacity.The present findings provide scientific evidence in the preparation technology of sea buckthorn polysaccharides with good antioxidant and bile acid binding capacity which are related to the structure affected by the extraction methods.

Corpus-based Contrastive Analysis of“Root”Metaphor Translation in Dream of the Red Mansion

Both the study of metaphor and translation has taken an empirical turn in the past decade,corpus-based method has provided a practical and objective way for investigating metaphor translation from a comparative and cognitive perspective.The purpose of this paper is to reveal the cognitive differences in the perception of“root”between English and Chinese through a contrastive analysis of the two English translations of a Chinese classic novel—Dream of the Red Mansion,the two translations are completed by a native Chinese speaker and a native English speaker respectively.The study is divided into two parts,the first part is devoted to a contrastive analysis of typical examples selected from the data acquired from the online English-Chinese parallel corpus with the online corpus analysis tool Wmatrix,two deductions have been drawn through the analysis concerning the cognition difference in root perception:(1)the integral perception of root and a plant in Chinese VS the binary cognition in English;(2)the concreteness of“root”metaphor in Chinese VS the abstractness in“root”metaphor application in English.Then the two deductions are further demonstrated through corpus-assisted study of“root”metaphor in large online corpuses.The differences in root metaphor usage as well as the cognitive reasons behind the differences have been investigated with emphasis not only on the dominant conceptual root metaphors,but also the semantic preference of the collocated words of the metaphors.

A Corpus-based Analysis of Keywords in Chinese Government Work Reports and State of the Union from the Perspective of Political Linguistics

This study compared and analyzed the features of keywords and their collocations in corpora:Chinese Government Work Reports and State of the Union(USA).A further comparison and analysis of the collocations of“develop”and“improve”was then conducted from the perspective of political linguistics.Results suggested that China and the United States have their own emphasis of government work.It was also indicated that“we”and“will”are both high-frequency keywords and combinations of“develop”and“improve”,which shows that both countries give the highest priority to narrowing the distance between the government and the public.

Audio Description for Educational Videos on COVID-19 Response:A Corpus-Based Study on Linguistic and Textual Idiosyncrasies

Audio description(AD),unlike interlingual translation and interpretation,is subject to unique constraints as a spoken text.Facilitated by AD,educational videos on COVID-19 anti-virus measures are made accessible to the visually disadvantaged.In this study,a corpus of AD of COVID-19 educational videos is developed,named“Audio Description Corpus of COVID-19 Educational Videos”(ADCCEV).Drawing on the model of Textual and Linguistic Audio Description Matrix(TLADM),this paper aims to identify the linguistic and textual idiosyncrasies of AD themed on COVID-19 response released by the New Zealand Government.This study finds that linguistically,the AD script uses a mix of complete sentences and phrases,the majority being in Present Simple tense.Present participles and the“with”structure are used for brevity.Vocabulary is diverse,with simpler words for animated explainers.Third-person pronouns are common in educational videos.Color words are a salient feature of AD,where“yellow”denotes urgency,and“red”indicates importance,negativity,and hostility.On textual idiosyncrasies,coherence is achieved through intermodal components that align with the video’s mood and style.AD style varies depending on the video’s purpose,from informative to narrative or expressive.

The material point method(MPM)has been gaining increasing popularity as an appropriate approach to the solution of coupled hydro-mechanical problems involving large deformation.In this paper,we survey the current state-of-the-art in the MPM simulation of hydro-mechanical behaviour in two-phase porous geomaterials.The review covers the recent advances and developments in the MPM and their extensions to capture the coupled hydro-mechanical problems involving large deformations.The focus of this review is aiming at providing a clear picture of what has or has not been developed or implemented for simulating two-phase coupled large deformation problems,which will provide some direct reference for both practitioners and researchers.

Deciphering gastric inflammation-induced tumorigenesis through multi-omics data and AI methods

Gastric cancer(GC), the fifth most common cancer globally, remains the leading cause of cancer deaths worldwide. Inflammation-induced tumorigenesis is the predominant process in GC development;therefore, systematic research in this area should improve understanding of the biological mechanisms that initiate GC development and promote cancer hallmarks. Here, we summarize biological knowledge regarding gastric inflammation-induced tumorigenesis, and characterize the multi-omics data and systems biology methods for investigating GC development. Of note, we highlight pioneering studies in multi-omics data and state-of-the-art network-based algorithms used for dissecting the features of gastric inflammation-induced tumorigenesis, and we propose translational applications in early GC warning biomarkers and precise treatment strategies. This review offers integrative insights for GC research, with the goal of paving the way to novel paradigms for GC precision oncology and prevention.

Volumetric lattice Boltzmann method for pore-scale mass diffusionadvection process in geopolymer porous structures

Porous materials present significant advantages for absorbing radioactive isotopes in nuclear waste streams.To improve absorption efficiency in nuclear waste treatment,a thorough understanding of the diffusion-advection process within porous structures is essential for material design.In this study,we present advancements in the volumetric lattice Boltzmann method(VLBM)for modeling and simulating pore-scale diffusion-advection of radioactive isotopes within geopolymer porous structures.These structures are created using the phase field method(PFM)to precisely control pore architectures.In our VLBM approach,we introduce a concentration field of an isotope seamlessly coupled with the velocity field and solve it by the time evolution of its particle population function.To address the computational intensity inherent in the coupled lattice Boltzmann equations for velocity and concentration fields,we implement graphics processing unit(GPU)parallelization.Validation of the developed model involves examining the flow and diffusion fields in porous structures.Remarkably,good agreement is observed for both the velocity field from VLBM and multiphysics object-oriented simulation environment(MOOSE),and the concentration field from VLBM and the finite difference method(FDM).Furthermore,we investigate the effects of background flow,species diffusivity,and porosity on the diffusion-advection behavior by varying the background flow velocity,diffusion coefficient,and pore volume fraction,respectively.Notably,all three parameters exert an influence on the diffusion-advection process.Increased background flow and diffusivity markedly accelerate the process due to increased advection intensity and enhanced diffusion capability,respectively.Conversely,increasing the porosity has a less significant effect,causing a slight slowdown of the diffusion-advection process due to the expanded pore volume.This comprehensive parametric study provides valuable insights into the kinetics of isotope uptake in porous structures,facilitating the development of porous materials for nuclear waste treatment applications.

Uncertainties of landslide susceptibility prediction: Influences of random errors in landslide conditioning factors and errors reduction by low pass filter method

In the existing landslide susceptibility prediction(LSP)models,the influences of random errors in landslide conditioning factors on LSP are not considered,instead the original conditioning factors are directly taken as the model inputs,which brings uncertainties to LSP results.This study aims to reveal the influence rules of the different proportional random errors in conditioning factors on the LSP un-certainties,and further explore a method which can effectively reduce the random errors in conditioning factors.The original conditioning factors are firstly used to construct original factors-based LSP models,and then different random errors of 5%,10%,15% and 20%are added to these original factors for con-structing relevant errors-based LSP models.Secondly,low-pass filter-based LSP models are constructed by eliminating the random errors using low-pass filter method.Thirdly,the Ruijin County of China with 370 landslides and 16 conditioning factors are used as study case.Three typical machine learning models,i.e.multilayer perceptron(MLP),support vector machine(SVM)and random forest(RF),are selected as LSP models.Finally,the LSP uncertainties are discussed and results show that:(1)The low-pass filter can effectively reduce the random errors in conditioning factors to decrease the LSP uncertainties.(2)With the proportions of random errors increasing from 5%to 20%,the LSP uncertainty increases continuously.(3)The original factors-based models are feasible for LSP in the absence of more accurate conditioning factors.(4)The influence degrees of two uncertainty issues,machine learning models and different proportions of random errors,on the LSP modeling are large and basically the same.(5)The Shapley values effectively explain the internal mechanism of machine learning model predicting landslide sus-ceptibility.In conclusion,greater proportion of random errors in conditioning factors results in higher LSP uncertainty,and low-pass filter can effectively reduce these random errors.

A Corpus-based Comparative Study of the Semantic Collocations of English and Chinese THROW Verbs

A verb plays an vital role in a sentence, therefore the study of this perspective attracts numerous scholars. Particularly, corpus-based study has increasing attention in recent years. The present study chooses the THROW verbs in both English and Chi?nese as the subject. The author applies"collocated"function or"pattern query"in two corpus, then analyzes the distinctions of the semantic collocation of the THROW verbs. The findings show that although these verbs belong to the same categorization in a limit?ed range of the specific histories and cultures, there is no one-to-one corresponding relation of these THROW verbs in translation across the two languages.

A Corpus-based Study on Differentiation of English Synonyms:“Conquer”“Overcome”and“Surmount”

Synonym differentiation has always been a difficulty in English learning. Traditionally, definitions and examples from dictionaries are taken to illustrate shades of differences between synonyms, which fails to provide a comprehensive description of these differences for students to differ synonyms. However, with the large volume, authentic materials, fast and convenient retrieval provided by corpus, the corpus-based synonym differentiation method can make a comprehensive description of synonyms in terms of their distinctive features in frequency distribution, collocation, colligation and semantic prosody. A corpus-based method will be employed to analyze the differences among the three English synonyms"conquer""overcome"and"surmount"based on the data collected from COCA (Corpus of Contemporary American English), so as to throw new light on synonym differentiation, offering a new way to study synonyms, and to provide references for lexical teaching and second language acquisition.

Sparse Modal Decomposition Method Addressing Underdetermined Vortex-Induced Vibration Reconstruction Problem for Marine Risers

When investigating the vortex-induced vibration(VIV)of marine risers,extrapolating the dynamic response on the entire length based on limited sensor measurements is a crucial step in both laboratory experiments and fatigue monitoring of real risers.The problem is conventionally solved using the modal decomposition method,based on the principle that the response can be approximated by a weighted sum of limited vibration modes.However,the method is not valid when the problem is underdetermined,i.e.,the number of unknown mode weights is more than the number of known measurements.This study proposed a sparse modal decomposition method based on the compressed sensing theory and the Compressive Sampling Matching Pursuit(Co Sa MP)algorithm,exploiting the sparsity of VIV in the modal space.In the validation study based on high-order VIV experiment data,the proposed method successfully reconstructed the response using only seven acceleration measurements when the conventional methods failed.A primary advantage of the proposed method is that it offers a completely data-driven approach for the underdetermined VIV reconstruction problem,which is more favorable than existing model-dependent solutions for many practical applications such as riser structural health monitoring.

A Corpus-based Analysis of Noun-verb Collocation of Knowledge

Corpus-based analysis is adopted to study the acceptable noun-verb collocation of the word knowledge. Verbs like acquire, have etc. are found to be frequently collocate with knowledge, and the Chinese students' favorite patterns like learn knowledge, enlarge knowledge are not acceptable. The finding may encourage teachers to consider about the pedagogical value of corpus while teaching languages.
