Intracerebral metaplastic meningioma with prominent ossification and extensive calcification
Jingxiang Huang,Fredrik Petersson
Rare Tumors , 2011, DOI: 10.4081/rt.2011.e20
Abstract: We present a patient (male 26 years) with a short history of recurrent seizures induced by a largely intracerebrally located frontal lobe meningioma. The tumor displayed a heretofore unpublished combination of extensive metaplastic bone formation and prominent non-psammomatous calcifications with focal chicken-wire pattern.
Gaussian Mixture Embeddings for Multiple Word Prototypes

Computer Science , 2015,
Abstract: Recently, word representation has been increasingly focused on for its excellent properties in representing the word semantics. Previous works mainly suffer from the problem of polysemy phenomenon. To address this problem, most of previous models represent words as multiple distributed vectors. However, it cannot reflect the rich relations between words by representing words as points in the embedded space. In this paper, we propose the Gaussian mixture skip-gram (GMSG) model to learn the Gaussian mixture embeddings for words based on skip-gram framework. Each word can be regarded as a gaussian mixture distribution in the embedded space, and each gaussian component represents a word sense. Since the number of senses varies from word to word, we further propose the Dynamic GMSG (D-GMSG) model by adaptively increasing the sense number of words during training. Experiments on four benchmarks show the effectiveness of our proposed model.

Advances in Applied Sociology (AASoci) , 2015, DOI: 10.4236/aasoci.2015.55015
Abstract: Patriotism is a kind of emotion, will, thought theory and behavior as a whole. The reaction of the complex relationship between individuals and country value system is formed in the process of social history, and it is developed and consolidated in the process of the history of human society, it is a kind of thought and feeling of loyalty and love their motherland. Under the background of contemporary economic globalization, some people that carry forward the patriotism produce confusion even think patriotism has become less important. From the perspective of the development of China and the world, this paper makes researches on contemporary value of patriotism, patriotism is of realistic significance on safeguarding national sovereignty and interests, and helps to achieve the China dream, deal with complex international environmental challenges, and participate in the international competition.

Cross-Cultural Communication , 2012, DOI: 10.3968/j.ccc.1923670020120806.1885
Abstract: Chinese Medicine as a treasure of Chinese people is a health care system used in China for more than four millenniums. Chinese Medicine has also been recognized as a popular complementary and alternative medicine in overseas countries. Media coverage usually reflects the attentions of society, because of the wide spread of Chinese Medicine, media around the world have a lot of reports concerning it. This study uses the media coverage downloaded from Nexis news media archive as data to build a corpus and conduct social survey on Chinese Medicine. The major purpose of this study is to see what topics are frequently included in the News Mentioning Chinese Medicine (NMCM) in order to find foreigners’ interests in Chinese Medicine and the overseas development of Chinese Medicine, and further analyze their specific fields. It is an attempt to apply corpus-based critical discourse analysis in the field of social survey. Key words: Chinese medicine; Media coverage; Corpus; Keyword analysis
Insulin Stimulates Adipogenesis through the Akt-TSC2-mTORC1 Pathway

PLOS ONE , 2009, DOI: 10.1371/journal.pone.0006189
Abstract: Background The signaling pathways imposing hormonal control over adipocyte differentiation are poorly understood. While insulin and Akt signaling have been found previously to be essential for adipogenesis, the relative importance of their many downstream branches have not been defined. One direct substrate that is inhibited by Akt-mediated phosphorylation is the tuberous sclerosis complex 2 (TSC2) protein, which associates with TSC1 and acts as a critical negative regulator of the mammalian target of rapamycin (mTOR) complex 1 (mTORC1). Loss of function of the TSC1-TSC2 complex results in constitutive mTORC1 signaling and, through mTORC1-dependent feedback mechanisms and loss of mTORC2 activity, leads to a concomitant block of Akt signaling to its other downstream targets. Methodology/Principal Findings We find that, despite severe insulin resistance and the absence of Akt signaling, TSC2-deficient mouse embryo fibroblasts and 3T3-L1 pre-adipocytes display enhanced adipocyte differentiation that is dependent on the elevated mTORC1 activity in these cells. Activation of mTORC1 causes a robust increase in the mRNA and protein expression of peroxisome proliferator-activated receptor gamma (PPARγ), which is the master transcriptional regulator of adipocyte differentiation. In examining the requirements for different Akt-mediated phosphorylation sites on TSC2, we find that only TSC2 mutants lacking all five previously identified Akt sites fully block insulin-stimulated mTORC1 signaling in reconstituted Tsc2 null cells, and this mutant also inhibits adipogenesis. Finally, renal angiomyolipomas from patients with tuberous sclerosis complex contain both adipose and smooth muscle-like components with activated mTORC1 signaling and elevated PPARγ expression. Conclusions/Significance This study demonstrates that activation of mTORC1 signaling is a critical step in adipocyte differentiation and identifies TSC2 as a primary target of Akt driving this process. Therefore, the TSC1-TSC2 complex regulates the differentiation of mesenchymal cell lineages, at least in part, through its control of mTORC1 activity and PPARγ expression.

Abstract: 1. There are 56 families of flora commonly distributed in Zhejiang, Taiwan Provinces of China and Japan. There are 71 families, 148 genera 222 species similar in Zhejiang and Japan, and 68 families, 135 genera, 214 species similar in Zhejiang and Taiwan Provinces. It denotes that the relationship of Zhejiang and Japan is closer than the relationship of Zhejiang and Taiwan.2. All kinds of elements of the tropical forest flora are common in Zhejiang, Taiwan and Japan. The common tropical elements in Zhejiang and Japan are 68 genera, i. e. 46 percent of the total common genera. There are 82 common genera of tropical elements in Zhejiang and Taiwan, i. e. 61 percent of the total common genera. It denotes that the relation of tropic elements of the later is more closer. than the former.3. The East Asian elements in Zhejiang and Japan arc onefold more than Zhejiang and Taiwans'. All kinds of the temperate elements, and the cosmopolitan genera in Zhejiang and Japan are much more than in Zhejiang and Taiwans'. For example, Rosaceae is common and much more in Zhejiang and Japan. It has 13 genera, 23 species, seven genera of them are the temperate (the North temperate one, the old world temperate one), four genera of them are the East Asian, one genus of them is the consmopolitan and the East Asian and the North American have one genus respectively. There are only two genera, four species of woody plants of Rosaceae in Zhejiangand Taiwan. They are all the North temperate elements.4. The endemic elements only exist in common flora of Zhejiang and Taiwan. There are no endemic common flora in Zhejiang and Japan. It shows that the division between Taiwan and the Continent happened at a later stage and the Continent has great influence on Taiwan.

Abstract: The seven free parameters were introduced into the governing equation of a motion to design new direct integral algorithms for solving structural dynamics problems. Two new one-step schemes were presented by selecting free parameters in the process of algorithmic finite difference analysis. The proposed methods are implicit, unconditionally stable, second-order accurate, numerically dissipative, and no overshot. One of the algorithms is able to annihilate the high-frequency modes asymptotically, and is more dissipative than Houbolt method for damped system. The numerical dissipation of the other method is minimum in the low-frequency regime and is controllable in the high-frequency regime. An analysis of the overshoot property is directly performed for damped system and show that proposed two algorithms no exhibits overshoot, while the HHT-a scheme suffers from the displacement and velocity overshoot simultaneously when damping existed. Finally, the results of the analysis were validated numerically by the comparison with the Newmark, HHT-a and Houbolt methods by analyzing a simulated two degree-of-freedom system representing a large structural.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0071730
Abstract: Objective The transcription factor 7-like 2 (TCF7L2) gene has been suggested to play an important role in the pathogenesis of cancer. However, the results have been inconsistent. In this study, we performed a meta-analysis to clarify the associations between TCF7L2 polymorphism and cancer risk. Methods Published literature from PubMed and EMBASE were retrieved. Pooled odds ratios (ORs) with 95% confidence interval (CIs) were calculated using fixed- or random-effects model. Results A total of 19 studies (14,814 cases and 33,856 controls) were identified for the analysis of the association between TCF7L2 polymorphism and cancer risk. The results showed that TCF7L2 polymorphism was associated with breast cancer (Homogeneous model: OR = 1.17, 95%CI = 1.02–1.35, I2 = 21.8%, p for heterogeneity = 0.276; Heterogeneous model: OR = 1.11, 95%CI = 1.03–1.20, I2 = 0.0%, p for heterogeneity = 0.543), prostate cancer (Homogeneous model: OR = 0.89, 95%CI = 0.84–0.96, I2 = 0.0%, p for heterogeneity = 0.640; Heterogeneous model: OR = 0.89, 95%CI = 0.84–0.95, I2 = 0.0%, p for heterogeneity = 0.871), and colon cancer (Heterogeneous model: OR = 1.15, 95%CI = 1.01–1.31, I2 = 0.0%, p for heterogeneity = 0.658), but not with colorectal cancer, lung cancer, and ovarian cancer. Conclusions The present meta-analysis indicated that there were significantly associations between the TCF7L2 rs7903146 polymorphism and risk of breast, prostate and colon cancers, rather than colorectal cancer, lung cancer, and ovarian cancer.

Abstract: In this paper, the nonlinear sloshing of liquid in a circle cylindrical tank under pitching excitation is studied analytically for the first time. Owing to the complexity of problem, it is very difficult to solve the nonlinear sloshing of liquid in a container subjected to forced pitching and (or) yawing oscillation by existing methods. Therefore, a method used to analyze this problem is presented. Firstly the nonlinear initial-boundary problem of PDE system for liquid sloshing in a container under pitching and (or) yawing excitation is established. With regard to the previous problem, variational principle and Lagrange function in the form of the volume integration of liquid pressure are obtained. Based on the variation equation and new Lagrange function proposed, nonlinear dynamic system for sloshing of liquid in a circle cylindrical container under pitching and (or) yawing excitation is derived. Subsequently, the nonlinear dynamic system gives the free surface kinematics and dynamic boundary condition. At the same time, the present method greatly reduces the work of formula derivation. Finally, the nonlinear dynamic system is solved by the multiple scale method. The dynamic characteristic of nonlinear liquid sloshing is analyzed in detail. Some kinds of motion which may appear in the liquid sloshing are discussed. Response curves and stable-unstable regions of liquid motion are determined. As to two-dimensional sloshing in a rigid, rectangular, open tank, the comparison between theoretical result by the present method and experiments shows good agreement. So, the present method is proved feasible. By means of the present method, the coupled dynamics of liquid in a tank and structure may also be investigated analytically.
