Water Metaphors in Dao de jing: A Conceptual Analysis  [PDF]
Yanying Lu
Open Journal of Modern Linguistics (OJML) , 2012, DOI: 10.4236/ojml.2012.24020
Abstract: This paper focuses on the use of water metaphors in the ancient Chinese text Dao de jing (168 BC), which is the foundational text of Daoism and a primary source of modern Chinese ideas about life and politics. The paper analyses how the image of water is used in the text to facilitate the conceptualization of the core philosophical concepts. The analysis is based on the theoretical framework of the Conceptual Metaphor Theory (Lakoff & Johnson, 1980; Kövecses, 2002). Water is discovered as occupying an essential position in the conceptualization of the Daoist worldview, which is manifested in notions of 道 dao and 德 de. It demonstrates that a cognitive approach offers an effective way to explore the cognitive basis of the text’s views on the eternal cosmological processing and of the application of morality in the human world.
Sub-10 fs laser pulses with repetition rate of 1.1 GHz by a Ti: sapphire oscillator
Qing Zhang,YanYing Zhao,ZhiYi Wei
Chinese Science Bulletin , 2009, DOI: 10.1007/s11434-009-0191-6
Abstract: We demonstrate a compact Ti: sapphire oscillator with ring cavity configuration. By optimizing the intracavity dispersion with chirped mirrors, pulses with repetition rate of 1.1 GHz are coupled out by the uncoated wedges in the cavity. Under 7W CW pump laser centered at 532 nm, the average power of the output pulses is about 30 mW, the duration is less than 10fs and the spectrum spans from 670 nm to 920 nm.
Sectoral Analysis of Energy Productivity Convergence: Empirical Evidence from Asian Countries  [PDF]
Dipa Adhikari, Yanying Chen
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.59090

This study examines the convergence of energy productivity at the sectoral level across 35 Asian countries from 1991 to 2011 by using the spatial panel data approach. The results reveal that mixed evidence of convergence process in the sectoral energy productivity for these 35 Asian countries. We found beta-convergence process exists in energy productivity in the construction, manufacturing, mining; manufacturing and utilities, transport; storage and communications, and wholesale; retail trade; restaurants and hotels sectors. While there is no evidence of energy productivity convergence in the agriculture; hunting; forestry and fishing sector over the study period. Moreover, the spatial spillover effect has a positive impact on the sectoral energy productivity growth in 35 Asian countries.

Mobility as a Service (MaaS): Challenges of Implementation and Policy Required  [PDF]
Yanying Li, Tom Voege
Journal of Transportation Technologies (JTTs) , 2017, DOI: 10.4236/jtts.2017.72007
Abstract: Mobility as a service (MaaS) is a relatively new concept, which holds the promise for a paradigm shift in the provision of urban mobility. The concept of MaaS is to use a single app to access and pay for various transport modes within a city or beyond; and the app will give options to allow a traveller to select the most suitable transport mode. The concept of MaaS is enabled by the current mass uptake of smartphones and social media as well ubiquitous internet connection. By studying current applications of MaaS in Europe and US conditions of operation of MaaS have been summarised. Based on the necessary conditions, a checklist has been developed for potential developers of MaaS to assess if they can implement MaaS in a city. This paper also discusses challenges of implementation of MaaS and their potential impacts on urban mobility and societal changes.
Survivin gene silencing sensitizes prostate cancer cells to selenium growth inhibition

Abstract: Expression of survivin was analyzed in a collection of normal and malignant prostatic tissues by immunohistochemical staining. In vitro studies were conducted in PC-3M, C4-2B, and 22Rv1 prostate cancer cells. The effect of selenium on survivin expression was analyzed by Western blotting and semi-quantitative RT-PCR. Survivin gene knockdown was carried out by transfecting cells with a short hairpin RNA (shRNA) designed against survivin. Cell proliferation was quantitated by the 3-(4,5-Dimethylthiazol-2-yl)- 2,5-Diphenyltetrazolium Bromide (MTT) assay and apoptosis by propidium iodide staining followed by flow cytometry analysis. Finally, in vivo tumor growth assay was performed by establishing PC-3M xenograft in nude mice and monitoring tumor growth following transfection and treatment.We found that survivin was undetectable in normal prostatic tissues but was highly expressed in prostate cancers. Survivin knockdown or selenium treatment inhibited the growth of prostate cancer cells, but the selenium effect was modest. In contrast to what have been observed in other cell lines, selenium treatment had little or no effect on survivin expression in several androgen-independent prostate cancer cell lines. Survivin knockdown sensitized these cells to selenium growth inhibition and apoptosis induction. In nude mice bearing PC-3M xenografts, survivin knockdown synergizes with selenium in inhibiting tumor growth.Selenium could inhibit the growth of hormone-refractory prostate cancer cells both in vitro and in vivo, but the effects were modest. The growth inhibition was not mediated by downregulating survivin expression. Survivin silencing greatly enhanced the growth inhibitory effects of selenium.Prostate cancer (PCa) is the second most commonly diagnosed cancer and the second leading cause of cancer deaths in men in the United States [1]. Surgery and radiation therapy are effective for localized disease [2], but there is no effective treatment strategy for recurrent or meta
Principles of Constructing Multiple-choice in Reading Comprehension of CET-4 and Their Enlightening to General College English Teaching
Yanying Xu
International Journal of English Linguistics , 2011, DOI: 10.5539/ijel.v1n1p219
Abstract: Reading comprehension multiple-choice (MC) is an indispensable part in College English Tests Band 4(CET-4) in China. The paper focuses on some principles of designing reading comprehension MC. To illustrate this, a detailed analysis is made on reading comprehension MC options taken from CET-4 to enlighten the general college English teachers to instruct their students to develop reading comprehension skill.
Summing up the Sentences in Active Voice without Passive Counterparts
Yanying Xu
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.7.828-831
Abstract: Some active English sentences can express passive implicature and they have no passive counterparts. In what cases can’t they convert into passive voice (or have no passive counterparts)? The paper will make a study on the problem from four various cases of active sentences without passive counterparts. By analyzing the four cases, the author draws a conclusion that the variety in English voice shows the tendency of the linguistic phenomenon of active voice taking the place of passivisation.
Supercontinuum generation and carrier envelope offset frequency measurement in a tapered single-mode fiber
Long Zhang,Hainian Han,Yanying Zhao,Lei Hou,Zijiao Yu,Zhiyi Wei
Physics , 2014, DOI: 10.1007/s00340-014-5942-7
Abstract: We report supercontinuum generation by launching femtosecond Yb fiber laser pulses into a tapered single-mode fiber of 3 um core diameter. A spectrum of more than one octave, from 550 to 1400 nm, has been obtained with an output power of 1.3 W at a repetition rate of 250 MHz, corresponding to a coupling efficiency of up to 60%. By using a typical f-2f interferometer, the carrier envelope offset frequency was measured and found to have a signal-to-noise ratio of nearly 30 dB.
Entropy, Substitution and Sustainable Economic Growth
Yanying Chen,Chunying Li
Research in World Economy , 2011, DOI: 10.5430/rwe.v2n2p66
Abstract: In the debate over sustainable economic growth, two critical issues are elasticity of substitution and technical change. Due to entropy increasing law in MEI system, the elasticity of substitution between any two resources must decline to zero and the efficiency improvement of resources from technical change is also limited. Therefore, substitution and technical change can not sustain economic growth forever.
Duality Theorems for Infinite Braided Hopf Algebras
Shouchuan Zhang,Yanying Han
Mathematics , 2003,
Abstract: Let $H$ be an infinite-dimensional braided Hopf algebra and assume that the braiding is symmetric on $H$ and its quasi-dual $H^d$. We prove the Blattner-Montgomery duality theorem, namely we prove $$ (R # H)# H^{d} \cong R \otimes (H # H^{d}) \hbox {as algebras in braided tensor category} {\cal C}.$$ In particular, we present two duality theorems for infinite braided Hopf algebras in the Yetter-Drinfeld module category.
