We present a novel approach to the exponential stability of switched functional differential equations. Our approach does not involve Lyapunov functions. It is simple and based upon spectral properties of Metzler matrices, a comparison principle and the average dwell-time technique. Consequently, some new explicit criteria for the exponential stability of switched functional differential equations are derived. Some illustrative examples are given. [ABSTRACT FROM AUTHOR]

As two neighboring countries, China and India not only have “emerging” economies, but also have a very important position and role in international political life. In addition to the trend of cooperation, China-India relations also take place in fierce competition in many fields, including energy security. From the early years of the twenty-first century, the need to exploit energy sources to serve the economic development of these two powers has become even more acute. This article focuses on some outstanding cooperation achievements as well as the fierce competition in the field of energy security between China and India in the first decade of the twenty-first century. At the same time, we also give some remarks on the relationship of China – India competition and cooperation on energy security in the aforementioned period.

This work addresses the global exponential stability of nonlinear delayed discrete-time systems with Markovian switching. By a novel approach, some explicit criteria for the exponential stability in mean square of such systems are derived. An application to discrete-time neural networks is presented.

The Nguyen Dynasty was the last monarchy in Vietnamese history, established after Nguyen Anh ascended the throne in 1802 and ended when Bao Dai abdicated in 1945, a total of 143 years. Stemming from the sense of protecting the throne of the feudal regime associated with the protection of national security, the Nguyen kings implemented foreign policy in a complicated historical context, especially was in the face of the growing pressure of Western colonialism. As a result , The Nguyen Kings had a “difficult problem” with behavioral culture and foreign policies with Western countries, particularly France, leading to implementing an “unclear” and “inconsistent” foreign pocily. This article presents a different perspective on the Nguyen Dynasty's relations with Western countries during the period of independence and self-control (1802-1858). Accordingly, the author look at the Nguyen Dynasty’s Diplomatic relations to the West in the view of the development, with the approach: From Limited access policy (under reigns of King Gia Long and King Minh Mang) to Anti-access policy (under reigns of King Thieu Tri and King Tu Duc). From there, it shows a different view of the contact process between Eastern and Western civilizations, specifically between Vietnam and other countries, such as France, Britain, and America in the Modern period.

The Sino-Philippines relations underwent many challenges and changes for over two decades. It is characterized as a "fighting and cooperating" relationship in various domains, specifically in the context of their long-standing dispute over the South China Sea (SCS). The two countries have established diplomatic ties since 1975, and although the relationship between the Philippines and China has gone a long way in forging economic relations with regard to conducting a more conducive, progressive, and fair-trade partnership, China is still perceived as a significant threat to the national security of the Philippines. The Philippine government has lodged numerous complaints with international bodies about China's violation of the law of the sea, particularly the UNCLOS. However, the regional environment and China's phenomenal rise in becoming an economic super power, and in particular the positive outcome resulting from the establishment of the ASEAN Economic Community (AEC), have all aided in developing the economic cooperation between the Philippines and China. Against the backdrop of these developments, the present article has focused on analyzing the two countries' relations in terms of the financial impacts from the surging waves of disagreements over the two countries' maritime belt areas in the South China Sea. It is also an empirical review of the literature on the myriad recommendations of international organizations, international courts, experts, jurists, and researchers, which seek to find solutions by providing legal viewpoints and political opinions on the issue of the maritime conflict between the Philippines and China. These are ongoing attempts for a peaceful solution to the maritime disputes between the two countries, as well as for the benefit of the rest of the ASEAN member nations. [ABSTRACT FROM AUTHOR]
