Hemorrhagic complications occur with a frequency of 1% to 10% during treatment for ACS. In fact, bleeding events are the most common extrinsic complication associated with ACS therapy. The identification of clinical characteristics and particularities of the antithrombin therapy associated with an increased risk of hemorrhagic complications would make it possible to adopt prevention strategies, especially among those exposed to greater risk. The international societies of cardiology renewed emphasis on bleeding risk stratification in order to decide strategy and therapy for patients with ACS. With this review, we performed an update about the ACS bleeding risk scores most frequently used in daily clinical practice.展开更多

We know that Amy Tan is a woman, what she has written about in Joy Luck Club reflects more about feminism. And it is a female novel to some extent. The author writes many things from a woman's perspective. But when it was adapted to a film, the director Wayne Wang deemphasized this part, and attached more importance to the Chinese immigrants as a whole group. As a Chinese American male director, he presents the novel mainly in a man's perspective. In this process, the main theme changed greatly. The adaptation of The Joy Luck Club is actually an adaptation from a feminist text to a cultural film.展开更多

As a result, more attention has been paid to the study of inertia-gravity waves, especially to the middle atmosphere gravity waves. This paper presents some aspects of inertia-gravity waves with emphasis on the propagation. Two methods are used here, namely, geometric optical method and physical optical method. We can see from the study that inertia-gravity waves are similar to planetary waves in some respects and they are different from planetary waves in others.展开更多

Monte Carlo simulation is used to generate random sea. An emphasis is placed on the nonlinear hydrodynamic force. Several distributions for the statistical estimation of extreme responses are compared. For Gumble distribution, the parameters of its asymptotic distribution expression have been checked. The results show that the Gumbel distribution agrees well with the simulated values of the responses.展开更多
