The Fallacy of Nuclear Primacy

"The United States is easily deterred by any nuclear armed state, even by the most primitive and diminutive of nuclear arsenals." Bruce G. Blair is the President of the World Security Institute. Chen Yali is the editor in chief of Washington Observer

The Oil Weapon: Myth of China's Vulnerability

The geopolitical canvass on which China plots its strategy for energy security displays a ubiquitous presence of one country: the United States. Chinese energy security planners must reckon with America's ravenous consumption of imported oil, its strategic alliances with other heavy importers of oil in Asia, its overseas military operations in the heart of the world's leading oil producing region, its naval dominion over the world's oil transportation routes, and the global domination of U.S. oil companies or multinational oil companies heavily capitalized by American investment. This is the context in which China pursues its energy security, sometimes blandly described as 'conservation and diversification of supply', which masks the nation's real struggle to satisfy its rapidly growing energy needs without exposing its energy lifelines to external forces that may, intentionally or not, betray China's interests

Resource Allocation for Device-to-Device Communications Underlaying Heterogeneous Cellular Networks Using Coalitional Games

Heterogeneous cellular networks (HCNs) with millimeter wave (mmWave) communications included are emerging as a promising candidate for the fifth generation mobile network. With highly directional antenna arrays, mmWave links are able to provide several-Gbps transmission rate. However, mmWave links are easily blocked without line of sight. On the other hand, D2D communications have been proposed to support many content based applications, and need to share resources with users in HCNs to improve spectral reuse and enhance system capacity. Consequently, an efficient resource allocation scheme for D2D pairs among both mmWave and the cellular carrier band is needed. In this paper, we first formulate the problem of the resource allocation among mmWave and the cellular band for multiple D2D pairs from the view point of game theory. Then, with the characteristics of cellular and mmWave communications considered, we propose a coalition formation game to maximize the system sum rate in statistical average sense. We also theoretically prove that our proposed game converges to a Nash-stable equilibrium and further reaches the near-optimal solution with fast convergence rate. Through extensive simulations under various system parameters, we demonstrate the superior performance of our scheme in terms of the system sum rate compared with several other practical schemes.Comment: 13 pages, 12 figure

Transnormal Functions and Focal Varieties on Finsler Manifolds

In this paper, we study transnormal functions and their level sets and focal varieties on complete Finsler manifolds. We prove that the focal varieties of a C2 transnormal function are smooth submanifolds and each regular level set is a tube over either of the focal varieties.Comment: 20 page

Appropriation, Rewriting and Alienation: A Postcolonial Critique of Mulan

Released in September, 2020, Mulan, a live-action film starring Liu Yifei, was adapted by Disney from the Ballad of Mulan[1]. The film was produced from its animated version Mulan (1998) which hit global box office amounting to 304 million with marvelous reputation. However, the live-action movie Mulan did not continue the brilliant results of the previous work. Instead, Mulan (2020) disappointed most Chinese audience[2] because historical facts and cultural values about Mulan were excessively appropriated, rewritten and alienated. Applying theories of Postcolonialism, this essay analyzes the live-action movie Mulan revealing the ethnocentric abuse of the target culture as the “other”: arbitrary appropriation, rewriting and distortion of its historical events and traditional values. Also, theories of popular culture will be used to analyze the cultural industry strategies applied in this unsuccessful film.[1]the Ballad of Mulan (Chinese: 木兰辞; pinyin: Mù lán cí), a famous folk song of the Northern Dynasty in China.[2]The investment in the live-action film Mulan is as high as US$200 million (about 1.4 billion RMB). As a result, the global box office is less than US$70 million. Also, the score in Douban is only 5.0 points. (the full mark is 10.)Sources:https://new.qq.com/rain/a/20201102A0J6EO00,https://movie.douban.com/subject/26357307
