G. R. BRINDHA,P. SWAMINATHAN,B. SANTHI

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 11,   Pages 1186-1198 doi: 10.1631/FITEE.1500283

Abstract: into data and to enhance opinion mining analysis, we propose a novel weighting scheme, referred to as inferredword weighting (IWW).IWW is computed based on the significance of the word in the document (SWD) and the significance of theword in the expression (SWE) to enhance their performance.

Syntactic word embedding based on dependency syntax and polysemous analysis None

Zhong-lin YE, Hai-xing ZHAO

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 4,   Pages 524-535 doi: 10.1631/FITEE.1601846

Abstract: Most word embedding models have the following problems: (1) In the models based on bag-of-words contexts, the structural relations of sentences are completely neglected; (2) Each word uses a single embedding, which makes the model indiscriminative for polysemous words; (3) Word embedding easily tends to contextualTo solve these problems, we propose an easy-to-use representation algorithm of syntactic word embeddingExperimental results show that our model generates desirable word embedding in similarity evaluation

interpretation of textbook vocabulary lists: comments on Xiao et al.’s Corpus-based research on English wordrecognition rates in primary school and word selection strategy Correspondence

Qiong HU, Ming YUE

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 7,   Pages 863-866 doi: 10.1631/FITEE.1700418

Abstract: Xiao et al. (2017)在对比分析4个语料库的基础上，提出国内小学六年级学生的识词率增长不能令人满意的观点，建议人教版小学英语通用教材总词汇在原有726个的基础上再增加903个，并删除twelfth（序数词，第十二）这样的低频词。作为外语教师和语言学家，我们赞同他们应用先进信息技术对传统词表进行评估的做法，但认为这项工作：1. 在构建参考语料库时需重视语料抽样的合理性；2. 在解读词频时需重视齐夫定律（Zipf’s law，即英语词频与词秩成反比）的作用——识字率增长随词汇量增加而减缓的情况是合理的；3. 在提出教材选词策略时，需考虑小学生认知特点和课业负担等现实因素限制，以及语言教育的总体目标，不能随便删除twelfth这样承载文化的词汇；4. 学龄儿童全国通用外语教材编写是项复杂的系统工程，需要各领域专家共同关注。

Uncovering the effect of poly(ethylene-co-vinyl alcohol) molecular weight and vinyl alcohol content on

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1484-1502 doi: 10.1007/s11705-023-2331-y

Abstract: Various hydrophilic poly(ethylene-co-vinyl alcohol) (EVOH) were used herein to precisely control the structure and hydrodynamic properties of polysulfone (PSF) membranes. Particularly, to prepare pristine PSF and PSF/EVOH blends with increasing vinyl alcohol (VOH: 73%, 68%, 56%), the non-solvent-induced phase separation (NIPS) technique was used. Polyethylene glycol was used as a compatibilizer and as a porogen in N,N-dimethylacetamide. Rheological and ultrasonic separation kinetic measurements were also carried out to develop an ultrafiltration membrane mechanism. The extracted membrane properties and filtration capabilities were systematically compared to the proposed mechanism. Accordingly, the addition of EVOH led to an increase in the rheology of the dopes. The resulting membranes exhibited a microporous structure, while the finger-like structures became more evident with increasing VOH content. The PSF/EVOH behavior was changed from immediate to delayed segregation due to a change in the hydrodynamic kinetics. Interestingly, the PSF/EVOH32 membranes showed high hydrophilicity and achieved a pure water permeability of 264 L·m–2·h–1·bar–1, which was higher than that of pure PSF membranes (171 L·m–2·h–1·bar–1). In addition, PSF/EVOH32 rejected bovine serum albumin at a high rate (> 90%) and achieved a significant restoration of permeability. Finally, from the thermodynamic and hydrodynamic results, valuable insights into the selection of hydrophilic copolymers were provided to tailor the membrane structure while improving both the permeability and antifouling performance.

Sharpest Contradiction and Most Favourable Opportunity ——A word on development of Chinese architectural

Wu Liangyong

Strategic Study of CAE 2004, Volume 6, Issue 2,   Pages 13-16

Abstract:

With the urbanization in China entering the period of accelerated development, the flourish of building industry has attracted numerous foreign architects offices to come to China for “seizing a beach before others”.The crisis for Chinese construction industry companies lies in the fact that they usually can not take charge of important projects but only act as secondaries or cooperators; urban planning and architectural design are not supported by comprehensive scientific demonstration and some big cities become test sites for freakish architectural designs of foreign architects; residential environment is not stressed on, economics and practicability is not given importance but instead peculiarity and novelty is one-sidedly sought for. This paper emphatically points out that architectural buildings and urban planning are closely related to the function, economy, technology, environment, etc. of a city, being an open macroscopic system of the city. Hence basic principles of architecture should be followed, more architectural factors should be considered so that architecture, landscape and urban planning are merged into a homogenous entirety. While the trend of globalization is tracked, more important is the inheritance and innovation of local and traditional culture. The academic level of a modern architect can only be based on his rich cultural background, trans-science learning and solid speciality knowledge.

Effects of molecular weight and concentration of carboxymethyl cellulose on morphology of hydroxyapatite

Ruiqiang LIU,Rattan LAL

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 804-812 doi: 10.1007/s11783-015-0785-y

Abstract: Nano-sized apatite particles (nAP) synthesized with carboxymethyl cellulose (CMC) have shown great application potentials in in situ heavy metal remediation. However, differences in CMC’s properties effects on the size of nAP produced are not well understood. In this paper, two types of CMC, with respective molecular weights (MW) of ~120000 and ~240000 Dalton or respective polymerization degrees of 500 (CMC-500) and 1050 (CMC-1050), were studied in a concentration range of 0.05%–0.5% (w/w) for nAP synthesis. Morphology of the particles was characterized with transmission electron microscopy (TEM). Results showed that 0.05% CMC-500 solution gave an average particle size of 148.7±134.9 nm, 0.25% CMC-500 solution produced particles of 21.8±20.4 nm, and, 0.5% CMC-500 solution contained particles of 15.8±7.7 nm. In comparison, 0.05% CMC-1050 solution produced nanoparticles of 6.8±3.2 nm, 0.25% CMC-1050 produced smaller nAP of 4.3±3.2 nm, and 0.5% CMC-1050 synthesized the smallest nanoparticles in this study, with an average diameter of 3.0±2.1 nm. Chemical composition of the products was identified with X-ray diffraction (XRD) as pure hydroxyapatite. Interactions between nAP and CMC were discussed with help of attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopic data. This study showed that CMC at higher concentration as well as higher MW facilitated to produce finer nanoparticles, showing that nAP size could be manipulated by selecting appropriate CMC MW and/or applying appropriate CMC concentration.
