In this process,the EU has also formed and developed its National Security Strategy and issued four versions of security strategy reports in 2003, 2008, 2016, and 2022. The 2022 version of the EU security strategy(hereafter referred to as the New Security Strategy), for the first time, has identified Russia as a long-term and direct threat. Furthermore, it has paid increased attention to traditional security, especially the upgrading of military capabilities and has become more reliant on the United States and the North Atlantic Treaty Organization. In the future, the EU will accelerate the militarization process, exert all-out efforts to contain Russia, scrutinize neighborhood security, and increase its swing on China policy.展开更多

Generally, successive governments in India have followed the basic principles articulated in Kautilya’s Arthasastra and various security practices adopted during the British Raj. India’s national security strategies are based on an internal logic of geopolitical rivalry and changes in international scenarios, and they are strongly influenced by Hindu traditions and the “Sad-Dharma” purported by King Ashoka. The objective is to create an India-dominated security order in the South Asian subcontinent, which persistently builds its capacity and system as a “net security provider” in the Indian Ocean Rim. Moreover, India is vigorously expanding its network of influence in the Pacific region in an effort to become a world leading power that enjoys a high level of strategic autonomy.展开更多

Based on the mechanism of physical attack to data remanence, the strategy intends to erase data remanence in memory cells once the power supply is removed, which disturbs attackers trying to steal the right information. Novel on-chip secure circuits including secure power supply and erase transistor are integrated into conventional SRAM to realize erase operation. Implemented in 0.25μm Huahong-NEC CMOS technology, an SRAM exploiting the proposed security strategy shows the erase operation is accomplished within 0.2 μs and data remanence is successfully eliminated. Compared with conventional SRAM, the retentive time of data remanence is reduced by 82% while the operation power consumption only increases by 7%.展开更多

In area of economics and trade, it pushes on the U.S.-Central Asian trade and investment framework agreement, focusing on developing trade in greater Central Asian region so as to encourage the regional countries to lower trade barriers and to advance reconfiguration of the regional countries and Afghanistan neighboring areas. In area of energy, it builds a greater Central Asian transportation network composed of highway, railway, natural gas-pipeline and electricity grid line to boom the regional trade and economy. In area of anti-terrorism, it strengthens security cooperation with the Central Asian countries. Meanwhile, it also pushes forward a multi-lateral security mechanism, increases economic aid, and promotes regional cooperation so as to achieve the regional lasting peace.展开更多

The annexation of Crimea, the hybrid war in Eastern Ukraine, and finally the unexpected interference in Syria--all these actions bring us back to the question of understanding the Russian motivation properly. Generally, it includes the whole interpretation of Russian strategic culture which is based on the research and analysis of the different factors： from literature and history to religion and political nature of the Russian state. Significant attempts to understand Moscow＇s strategic culture were made by the American experts during the Cold War; therefore the article analyzes the main pillars of Russian strategic culture, its continuity and change in comparison to Soviet times as well as the main reactions of Moscow for what it considers to be a threat.展开更多

Information structure is given by an event tree. This paper restricts attention to purely financial securities. It is assume that trading takes place in the sequence of spot markets and futures markets for securities payable in units of account. Unlimited short selling in securities is allowed. Financial markets may be incomplete: some consumption streams may be impossible to obtain by any trading strategy. Securities may be individually precluded from trade at arbitrary states and dates. The security price process is arbitrage free the dividend process if and only if there exists a stochstic state price (present value) process: the present value of the security prices at every vertex is the present value of their dividend and capital values over the set of immediate successors; the current value of each security at every vertex is the present value of its future dividend stream over all succeeding vertices. The existence of such an equilibrium is proved under the following condition: continuous, weakly convex, strictly monotone and complete preferences, strictly positive endowments and dividends processes.展开更多
