Nevertheless, the reality of "hot economic relations vs. cold political relations" between the two countries puzzles people who show deep concern for Sino-Japanese relations: Are the inherent features of Sino-Japanese relations the cause of the phenomenon? Is the gap between aspiration and action the cause of it? Or both are the causes? The answer is there, but exploration needs to be made. In October 2003, the Export Forum of Contemporary Internation- al Relations held a discussion on "the Future of Sino-Japanese Relations. " On June 5, 2004, the forum further sponsored a symposium, inviting four members of the 21st Century Committee for Sino-Japanese Friendship to have a discussion on "Suggestions to Promote Sino-Japanese Relations" in Wanshou Housing Estate. Based on the current situation of Sino- Japanese relations and on "pulse-feeling" and "group consultation," the four members of the 21st Century Committee for Sino-Japanese Friendship in Beijing tried to write out a "prescription" for the development of Sino-Japanese relations. Though the speeches of the four members vary in length and even differ in views, we sincerely hope the discussion could attract your high attention to Sino-Japanese relations so as to make joint effort to bring Sino-Japanese relations to step onto the right track for healthy development.展开更多

This also marks a later phase of the Abe administration has solidified its later phase, following Abe's second rise to power. The supremacy of the LDP and the administration of the basket of economic policies termed Abenomics have produced initial effects, and the overall climate of political opinion in Japan remains largely conservative, all factors favorable the continuance of Abe's regime. A major task in the future to cement AbeJ s political legacy would be amendment of Japan’ s pacifist constitution. Abe’ s political and security policies are likely not to change, namely, the promotion of multilateral cooperation in the US-Japan alliance, a moderate adjustment of Japan's China policy, and a return to utilitarian diplomacy to maximize Japan’s national interests. Thanks to the return of the Sino-Japanese relationship to the right track, the healthy development of bilateral relations depends on the consolidation of the political foundation, deepening mutually beneficial cooperation, and constructively managing and controlling disagreement.展开更多

On the other hand, we prove that the wave-function of a generalized diffraction in time problem is just the Fourier-transform of a truncated function. Consequently, the existence of dispersion relations for the diffraction in time wave-function follows. We derive these explicit dispersion relations.展开更多

It is found that the dispersion relation can be manipulated by strains through magneto-elastic coupling. Especially, the allowed bands and forbidden bands in dispersion relations shift to higher frequency with strain changing from compressive to tensile,while shifting to lower frequency with strain changing from tensile to compressive. We also confirm that the spin wave with specific frequency can pass the magnonic crystal or be blocked by tuning the strains. The result provides an advanced platform for studying the tunable skyrmion-based spin wave devices.展开更多

Over the past forty years, various versions of the modified scenario have been proposed to simulate the effects of missing mass. These schemes replace the dynamic effect of dark matter by introducing some tiny extra force terms in the dynamic equations. Such extra forces have mainly interactions on large scales of galaxies, such as fitting the Tully-Fisher relation or asymptotically flat rotation curves. The discussion in this paper shows that the evidence of taking the modified schemes as fundamental theory is still insufficient. In this paper, we display a system of simplified galactic dynamical equations derived from weak field and low-speed approximations of Einstein field equations, and then we use it to discuss two important empirical relations in galactic dynamics, namely the Faber-Jackson relation and Tully-Fisher relation, as well as the related fundamental plane. These discussions provide a reference scheme for improving the dispersion of the empirical relations, and also provide a theoretical foundation to analyze the properties of dark matter and galactic structures.展开更多
