A Comparative Study to Understanding about Poetics Based on Natural Language Processing  [PDF]
Lingyi Zhang, Junhui Gao
Open Journal of Modern Linguistics (OJML) , 2017, DOI: 10.4236/ojml.2017.75017
Abstract: This paper tries to find out five poets’ (Thomas Hardy, Wilde, Browning, Yeats, and Tagore) differences and similarities through analyzing their works on nineteenth Century by using natural language understanding technology and word vector model. Firstly, we collect enough poems from these five poets, build five corpus respectively, and calculate their high-frequency words, by using Natural Language Processing method. Then, based on the word vector model, we calculate the word vectors of the five poets’ high-frequency words, and combine the word vectors of each poet into one vector. Finally, we analyze the similarity between the combined word vectors by using the hierarchical clustering method. The result shows that the poems of Hardy, Browning, and Wilde are similar; the poems of Tagore and Yeats are relatively close—but the gap between the two is relatively large. In addition, we evaluate the stability of our approach by altering the word vector dimension, and try to analyze the results of clustering in a literary (poetic) perspective. Yeats and Tagore possessed a kind of mysticism poetics thought, while Hardy, Browning, and Wilde have the elements of realism combined with tragedy and comedy. The results are similar comparing to those we get from the word vector model.
Research on the Interaction between Producer Services and Manufacturing Industry in Shaanxi Province  [PDF]
Lingyi Kong, Xiao Liang
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.85087
Abstract: With the deepening of social division of labor, producer services are gradually separated from manufacturing industry and play a more and more important role in the national economy. In particular, with the rapid development of scientific research, business, law, finance and other industries, the industrial association between the productive service industry and the manufacturing industry becomes more closely. The interactive state between the producer services and manufacturing industry has a direct impact on the industrial upgrading and structural adjustment of all sectors of the national economy, which has become an important way for the economic development of our country in the future. Taking Shaanxi Province as an example, this paper first analyzes the development of producer services and manufacturing in Shaanxi. On this basis, the VAR model is built to analyze the added value of two industries in Shaanxi Province. Finally, according to the empirical results, we put forward relevant countermeasures and suggestions.

Abstract: 提出了一种自顶向下的基于晶体管级的全定制IP漏电流功耗计算方法,该方法计算快速高效,实用性强,取代了以往完全依靠软件仿真进行功耗计算的技术.在设计龙芯 号CPU中的全定制IP时应用了此方法,该芯片采用的是中芯国际0 .18μm CMOS工艺技术.为了验证该方法,把计算结果与Synopsys公司的Nanosim仿真结果进行对比,误差只有10 %左右.由于软件仿真需要大量的测试激励与计算时间,而该方法不需要外加测试激励便可以计算出全定制IP漏电流功耗,并能快速找到其模块所在位置,使设计周期大为缩短,因此完全可以针对这种计算方法开发相应软件及进行应用

Nicotine Promotes Proliferation of Human Nasopharyngeal Carcinoma Cells by Regulating α7AChR, ERK, HIF-1α and VEGF/PEDF Signaling

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0043898
Abstract: Nicotine, the major component in cigarette smoke, can promote tumor growth and angiogenesis, but the precise mechanisms involved remain largely unknown. Here, we investigated the mechanism of action of nicotine in human nasopharyngeal carcinoma (NPC) cells. Nicotine significantly promoted cell proliferation in a dose and time-dependent manner in human NPC cells. The mechanism studies showed that the observed stimulation of proliferation was accompanied by the nicotine-mediated simultaneous modulation of α7AChR, HIF-1α, ERK and VEGF/PEDF signaling. Treatment of NPC cells with nicotine markedly upregulated the expression of α7AChR and HIF-1α proteins. Transfection with a α7AChR or HIF-1α-specific siRNA or a α7AChR-selective inhibitor significantly attenuated the nicotine-mediated promotion of NPC cell proliferation. Nicotine also promoted the phosphorylation of ERK1/2 but not JNK and p38 proteins, thereby induced the activation of ERK/MAPK signaling pathway. Pretreatment with an ERK-selective inhibitor effectively reduced the nicotine-induced proliferation of NPC cells. Moreover, nicotine upregulated the expression of VEGF but suppressed the expression of PEDF at mRNA and protein levels, leading to a significant increase of the ratio of VEGF/PEDF in NPC cells. Pretreatment with a α7AChR or ERK-selective inhibitor or transfection with a HIF-1α-specific siRNA in NPC cells significantly inhibited the nicotine-induced HIF-1α expression and VEGF/PEDF ratio. These results therefore indicate that nicotine promotes proliferation of human NPC cells in vitro through simultaneous modulation of α7AChR, HIF-1α, ERK and VEGF/PEDF signaling and suggest that the related molecules such as HIF-1α might be the potential therapeutic targets for tobacco-associated diseases such as nasopharyngeal carcinomas.

Current progress and prospects of induced pluripotent stem cells
LingYi Chen,Lin Liu
Science China Life Sciences , 2009, DOI: 10.1007/s11427-009-0092-6
Abstract: Induced pluripotent stem (iPS) cells are derived from somatic cells by ectopic expression of few transcription factors. Like embryonic stem (ES) cells, iPS cells are able to self-renew indefinitely and to differentiate into all types of cells in the body. iPS cells hold great promise for regenerative medicine, because iPS cells circumvent not only immunological rejection but also ethical issues. Since the first report on the derivation of iPS cells in 2006, many laboratories all over the world started research on iPS cells and have made significant progress. This paper reviews recent progress in iPS cell research, including the methods to generate iPS cells, the molecular mechanism of reprogramming in the formation of iPS cells, and the potential applications of iPS cells in cell replacement therapy. Current problems that need to be addressed and the prospects for iPS research are also discussed.
Economic Determinants of Happiness
Teng Guo,Lingyi Hu
Statistics , 2011,
Abstract: Many scholars have recently begun to dispute the assumed link between individual wellbeing and economic conditions and the extent to which the latter matters (Easterlin, 1995; Stevenson and Wolfers 2008; Tella and MacCulloch 2008). This dilemma is empirically demonstrated in the Latin America Public Opinion Project (LAPOP, 2011), which surveyed North and Latin America in terms of perceived life satisfaction. Higher measures found in the less developed countries of Brazil, Costa Rica, and Panama than in North America pose an intriguing quandary to traditional economic theory. In light of this predicament this paper aims to construct a sensible measure of the national happiness level for the United States on a year by year basis; and regress this against indicators of the national economy to provide insight into this puzzling enigma between national happiness and economic forces

Abstract: A sub-mA phase-locked loop fabricated in a 65nm standard digital CMOS process is presented.The impact of process variation is largely removed by a novel open-loop calibration that is performed only during start-up but is opened during normal operation.This method reduces calibration time significantly compared with its closed-loop counterpart.The dual-loop PLL architecture is adopted to achieve a process-independent damping factor and pole-zero separation.A new phase frequency detector embedded with a level shifter is introduced.Careful power partitioning is explored to minimize the noise coupling.The proposed PLL achieves 3.1ps RMS jitter running at 1.6GHz while consuming only 0.94mA.
