Overall view of the north side (front of the monument) looking towards the Mausoleum of Mao Zedong; A ten-story obelisk (stele) that was erected as a national monument of the People's Republic of China to the martyrs of revolutionary struggle during the 19th and 20th centuries. It is located in the southern edge of Tiananmen Square, to the north of Mausoleum of Mao Zedong. Commissioned by the government in 1949, it was completed in 1958. The architect of the monument was Liang Sicheng, with some elements designed by his wife, Lin Huiyin (an architect and the aunt of Maya Lin). The monument has also served as the center of large-scale mourning activities that later developed into protest and unrest, such as the deaths of Premier Zhou Enlai (which developed into the Tiananmen Square protests of 1976) and Hu Yaobang (which developed into the Tiananmen Square protests of 1989). The monument covers an area of 32,000 square feet. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 4/26/2013

The impacts of overseas M&A on shareholder wealth: evidence from Chinese listed companies

The recent review of literature on M&A focuses on two issues: firstly, whether the borderline M&A made by Chinese companies can create shareholder prosperity; secondly are the factors that influence the prosperity of cross-border M&A. This paper will examine the influence of cross-border M&A on shareholder wealth of listed Chinese companies during the process when they seek their way of development, as well as make a systemic and multivariate analysis of the influencing mechanism. The cross-border M&A created by Chinese A-share listed firms Shenzhen and in Shanghai stock exchange market from 2003 to 2017 are used as samples, and the event survey is used in the evaluation of cumulative abnormal return as well as the chosen firms in the event window. A multiple regression analysis will be used to evaluate the factors that affects wealth at a cross-border M&A in relation to nation, industry and company. The empirical study shows that Chinese companies' cross border M&A will generate substantial and optimistic cumulative abnormal return, which shows that the stock market and the investors holds a positive attitude towards M&A. Cross-border M&A shall still be a strategic choice for Chinese companies to implement the "going-out" strategy, enhance their market power, reduce costs, and enhance global competitiveness. The multiple regression model results indicate a positive correlation between the investors' attitude towards the cross-border M&A and the host country's free economic system, the host company's diversified structure, the scale of M&A and their rich international experience. While, a developed host country, a related industry, the high-tech industry, the company scale, the M&A experience of the host country and its governance will have a undesirable effect on its fortune result

APSE: Attention-aware polarity-sensitive embedding for emotion-based image retrieval

With the popularity of social media, an increasing number of people are accustomed to expressing their feelings and emotions online using images and videos. An emotion-based image retrieval (EBIR) system is useful for obtaining visual contents with desired emotions from a massive repository. Existing EBIR methods mainly focus on modeling the global characteristics of visual content without considering the crucial role of informative regions of interest in conveying emotions. Further, they ignore the hierarchical relationships between coarse polarities and fine categories of emotions. In this paper, we design an attention-aware polarity-sensitive embedding (APSE) network to address these issues. First, we develop a hierarchical attention mechanism to automatically discover and model the informative regions of interest. Specifically, both polarity-and emotion-specific attended representations are aggregated for discriminative feature embedding. Second, we propose a generated emotion-pair (GEP) loss to simultaneously consider the inter-and intra-polarity relationships of the emotion labels. Moreover, we adaptively generate negative examples of different hard levels in the feature space guided by the attention module to further improve the performance of feature embedding. Extensive experiments on four popular benchmark datasets demonstrate that the proposed APSE method outperforms the state-of-the-art EBIR approaches by a large margin

Single-cell transcriptome sequencing reveals heterogeneity of gastric cancer: progress and prospects

Gastric cancer is one of the most serious malignant tumor and threatens the health of people worldwide. Its heterogeneity leaves many clinical problems unsolved. To treat it effectively, we need to explore its heterogeneity. Single-cell transcriptome sequencing, or single-cell RNA sequencing (scRNA-seq), reveals the complex biological composition and molecular characteristics of gastric cancer at the level of individual cells, which provides a new perspective for understanding the heterogeneity of gastric cancer. In this review, we first introduce the current procedure of scRNA-seq, and discuss the advantages and limitations of scRNA-seq. We then elaborate on the research carried out with scRNA-seq in gastric cancer in recent years, and describe how it reveals cell heterogeneity, the tumor microenvironment, oncogenesis and metastasis, as well as drug response in to gastric cancer, to facilitate early diagnosis, individualized therapy, and prognosis evaluation

Barrett’s Esophagus and Intestinal Metaplasia

Intestinal metaplasia refers to the replacement of the differentiated and mature normal mucosal epithelium outside the intestinal tract by the intestinal epithelium. This paper briefly describes the etiology and clinical significance of intestinal metaplasia in Barrett’s esophagus. This article summarizes the impact of intestinal metaplasia on the diagnosis, monitoring, and treatment of Barrett’s esophagus according to different guidelines. We also briefly explore the basis for the endoscopic diagnosis of intestinal metaplasia in Barrett’s esophagus. The identification techniques of goblet cells in Barrett’s esophagus are also elucidated by some scholars. Additionally, we further elaborate on the current treatment methods related to Barrett’s esophagus

The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys
