When a famous Federation scientist dies, his son puts his inventions up for sale to the highest bidder, be they Federation, Klingon, Romulan, or Cardassian. Among the items at auction is a photon pulse canon capable of punching through a starship's shields with a single shot. Meanwhile, Wesley Crusher is kidnapped from the Academy by renegade Ferengi who have set their sights on the photon canon as well, and Captain Picard must outmaneuver enemies on every side to save Wesley and protect the EnterpriseTM from the deadly fire of the new canon.

The year 2009 marks the 30th anniversary of normalization of Sino-U.S. relations. Over the past 30 years, the bilateral relations have developed by twists and turns. It is not until recent years that some stability and forward-looking exchanges have returned to the central stage, albeit tension, grievances, and mistrust continue to persist. Washington has encouraged China to become a “responsible stakeholder” in the world affairs, while China has urged the U.S. to work with China to build a “harmonious world.” Both sides want to work together to solve their differences through dialogs and negotiations. In the wake of the worldwide financial crisis of 2008–2009, China has contributed greatly in financing the crumbling U.S. financial market and lent a helping hand in stabilizing the world economy. Nevertheless, the foundation of the relationship remains very fragile and the long-term prospect for a constructive cooperative relationship is still full of uncertainties. For many Americans, China’s increasing global reach and growing political and economic influence constitute the greatest challenge to world dominance by the United States. As a result, some perceive China’s rise as a threat to Americans’ core national interests. The recent changes in the global geostrategic landscape and economic interdependence have suggested that some new ideas, factors, conditions, and elements are shaping the relations between the two countries. The task of Thirty Years of China-U.S. Relations: Analytical Approaches and Contemporary Issues is to explore these factors, issues, and challenges and their impact for the bilateral relations in the 21st century.

With the considerable increase of AI applications, AI is being increasingly used to solve optimization problems in engineering. In the past two decades, the applications of artificial intelligence in power systems have attracted much research. This book covers the current level of applications of artificial intelligence to the optimization problems in power systems. This book serves as a textbook for graduate students in electric power system management and is also useful for those who are interested in using artificial intelligence in power system optimization.

Energy has been an inevitable component of human lives for decades. Recent rapid developments in the area require analyzing energy systems not as independent components but rather as connected interdependent networks. The Handbook of Networks in Power Systems includes the state-of-the-art developments that occurred in the power systems networks, in particular gas, electricity, liquid fuels, freight networks, as well as their interactions. The book is separated into two volumes with three sections, where one scientific paper or more are included to cover most important areas of networks in power systems. The first volume covers topics arising in electricity network, in particular electricity markets, smart grid, network expansion, as well as risk management. The second volume presents problems arising in gas networks; such as scheduling and planning of natural gas systems, pricing, as well as optimal location of gas supply units. In addition, the second volume covers the topics of interactions between energy networks. Each subject is identified following the activity on the domain and the recognition of each subject as an area of research. The scientific papers are authored by world specialists on the domain and present either state-of-the-arts reviews or scientific developments.
