On the Accusative Weapon of the Poetic Image of London in William Blake’s London against the Brutalities of English Realities  [PDF]
Jun Luo, Guijun Li
Advances in Literary Study (ALS) , 2018, DOI: 10.4236/als.2018.62008
Abstract: Although he has not been accepted as a famous English poet by the mainstream consciousness of his poetic production at his age, William Blake is now extensively regarded as one of the earliest and greatest figures who have pioneered the early romanticism in English literature. His typical poems have been discussed for a long time from various perspectives but the role of the image of London in his emblematic poem London has rarely been touched by scholars to make an exploration of the critical spirits of the poet. To attach an academic importance on the academic values in this respect, this essay will take London as an analytical sample to justify that the image of London in William Blake’s London can be taken as an accusative weapon against the social brutalities of England in reference to the social reality of that repressive time based on a better analysis of the image of London in this poem from the perspective of reflectionism in terms of the social oppression, class repression, religious misconduct as much as liberal exploitation of English society as what can be seen in the poetic images of this poem.
On the Euphemistic Insinuation of the Historical Reality of America in the Poetic Historicity of I, Too, Sing America  [PDF]
Jun Luo, Guicai Chen
Advances in Literary Study (ALS) , 2019, DOI: 10.4236/als.2019.72007
Abstract:
In the historical observation of Harlem Renaissance that has already been epitomized in the historical elaboration in the poetic production of Langston Hughes, what his readers have been insatiable with is that although both international and Chinese scholars and critics have not only made various valuable explorations of his poetic texts but also made a mention of the lower social position and their unfair treatment of the dark brothers in the American society dominated by whites’ culture, they have hardly devoted their studies to this poetic text titled I, Too, Sing America to quest for the historical reality embedded euphemistically in the textual interweavement of this poetic text. Owing to their failure to do so in their studies, this paper will try to make an exploration of the euphemistic representation of the profound reality grounded on poetic historicity of this poetic text that dwells on historical reality of the miserable lots of those dark brothers.
SNAP: SNowbAll multi-tree Pushing for Peer-to-Peer Media Streaming
Jun Luo
Computer Science , 2010,
Abstract: Given the respective advantages of the two complimentary techniques for peer-to-peer media streaming (namely tree-based push and mesh-based pull), there is a strong trend of combining them into a hybrid streaming system. Backed by recently proposed mechanisms to identify stable peers, such a hybrid system usually consists of backbone trees formed by the stable peers and other overlay structures in the second tier to accommodate the remaining peers. In this paper, we embrace the hybrid push-pull structure for peer-to-peer media streaming. Our protocol is dominated by a multi-tree push mechanism to minimize the delay in the backbone and is complemented by other overlay structures to cope with peer dynamics. What mainly distinguishes our multi-tree pushing from the conventional ones is an unbalanced tree design guided by the so called snow-ball streaming, which has a provable minimum delay and can be smoothly "melded" with virtually any other existing overlay structures lying in the second tier. We design algorithms to construct and maintain our SNowbAll multi-tree Pushing (SNAP) overlay, and we also illustrate how to smoothly weld the SNAP backbone with the second tier. Finally, we perform simulations in ns-2; the results indicate that our approach outperforms a recently proposed hybrid streaming system.
A New Test for Large Dimensional Regression Coefficients  [PDF]
June Luo, Yi-Jun Zuo
Open Journal of Statistics (OJS) , 2011, DOI: 10.4236/ojs.2011.13025
Abstract: In the article, hypothesis test for coefficients in high dimensional regression models is considered. I develop simultaneous test statistic for the hypothesis test in both linear and partial linear models. The derived test is designed for growing p and fixed n where the conventional F-test is no longer appropriate. The asymptotic distribution of the proposed test statistic under the null hypothesis is obtained.
Measurement of Cooling Effect of Building Environment Greening  [PDF]
Qinghai Luo, Jun Zou, Xiufei Yang
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.37068
Abstract: A series of measurements showed that community greening and trees shading had different degree of cooling effect. The cooling effect of wall greening was related to factors such as heat storage capacity and the orientation of the wall, climatic conditions. As compared to the heat reduced by sheltering the solar radiation, the heat absorbed by plant transpiration had greater cooling contribution. Comprehensive considering environment, technology and economics factors, the building district greening should take trees as the priority. The trees shading can significantly drop indoor temperature and temperature fluctuation, also created better condition for night-time natural ventilation.
Adverse Events of Extracorporeal Ultrasound-Guided High Intensity Focused Ultrasound Therapy
Tinghe Yu, Jun Luo
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0026110
Abstract: Background High-intensity focused ultrasound (HIFU) is considered to be an alternative to surgery. Extracorporeal ultrasound-guided HIFU (USgFU) has been clinically used to treat solid tumors. Preliminary trials in a small sample of a Western population suggested that this modality was safe. Most trials are performed in China thereby providing comprehensive data for understanding the safety profile. The aim of this study was to evaluate adverse events of USgFU therapy. Methods and Findings Clinical data were searched in 2 Chinese databases. Adverse events of USgFU were summarized and compared with those of magnetic resonance-guided HIFU (MRgFU; for uterine, bone or breast tumor) and transrectal ultrasound-guided HIFU (for prostate cancer or benign prostate hyperplasia). USgFU treatment was performed using 7 types of device. Side effects were evaluated in 13262 cases. There were fewer adverse events in benign lesions than in malignant lesions (11.81% vs. 21.65%, p<0.0001). Rates of adverse events greatly varied between the disease types (0–280%, p<0.0001) and between the applied HIFU devices in both malignant (10.58–44.38%, p<0.0001) and benign lesions (1.67–17.57%, p<0.0001). Chronological analysis did not demonstrate a decrease in the rate of adverse events. Based upon evaluable adverse events, incidences in USgFU were consistent with those in MRgFU or transrectal HIFU. Some side effects frequently occurred following transrectal HIFU were not reported in USgFU. Several events including intrahepatic metastasis, intraoperative high fever, and occlusions of the superior mesenteric artery should be of particular concern because they have not been previously noted. The types of adverse events suggested that they were ultrasonic lesions. Conclusion The frequency of adverse events depended on the location of the lesion and the type of HIFU device; however, side effects of USgFU were not yet understood. USgFU did not decrease the incidence of adverse events compared with MRgFU.
Prediction for human transcription start site using diversity measure with quadratic discriminant
Jun Lu,Liaofu Luo
Bioinformation , 2008,
Abstract: The accurate identification of promoter regions and transcription start sites is a challenge to the construction of human transcription regulation networks. Thus, an efficient prediction method based on theoretical formulation is necessary for this purpose. We used the method of increment diversity with quadratic discriminant analysis (IDQD) to predict transcription start sites (TSS). The method produced sensitivity and positive predictive value of more than 65% with positives to negatives ratio of 1:58. The performance evaluation using Receiver Operator Characteristics (ROC) showed an auROC (area under ROC) of greater than 96%. The evaluation by Precision Recall Curves (PRC) showed an auPRC (area under PRC) of about 26% for positives to negatives ratio of 1:679 and about 64% for positives to negatives ratio of 1:113. The results documented in this approach are either better or comparable to other known methods.
NMR Quantum Computation with a hyperpolarized nuclear spin bulk
Jun Luo,Xizhi Zeng
Physics , 1998,
Abstract: We consider two new quantum gate mechanisms based on nuclear spins in hyperpolarized solid $^{129}Xe$ and HCl mixtures and inorganic semiconductors. We propose two schemes for implementing a controlled NOT (CNOT) gate based on nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) from hyperpolarized solid $^{129}Xe$ and HCl mixtures and optically pumped NMR in semiconductors. Such gates might be built up with particular spins addressable based on MRI techniques and optical pumping and optical detection techniques. The schemes could be useful for implementing actual quantum computers in terms of a cellular automata architecture.

Moran Sets and Hyperbolic Boundaries
Jun Jason Luo
Mathematics , 2012, DOI: 10.5186/aasfm.2013.3814
Abstract: In the paper, we prove that a Moran set is homeomorphic to the hyperbolic boundary of the representing symbolic space in the sense of Gromov, which generalizes the results of Lau and Wang [Indiana U. Math. J. {\bf 58} (2009), 1777-1795]. Moreover, by making use of this, we establish the Lipschitz equivalence of a class of Moran sets.
