The Trump Administration’s Nuclear Posture Review: Back to Great Power Competition

Assessing the Nuclear Posture Review

The spread of nuclear weapons to potential U.S. adversaries raises important questions for U.S. nuclear strategy and foreign policy. During the Cold War, U.S. nuclear strategy was designed to meet the challenges posed by the Soviet Union, a superpower adversary that deployed an enormous nuclear arsenal and was viewed as a threat to vital U.S. interests. Today the United States faces a strikingl...

The Great Debate Schools Programme: Nuclear power is the answer to the world’s energy problems

The debate about nuclear power for electricity generation is one that has run for decades, with ever changing terms of reference. The 1970s and 1980s saw a significant expansion in numbers of nuclear power plants in Europe and the US and a parallel growth of anti-nuclear movements which focused on three different areas: health considerations, associated with fears about exposure to radiation; p...

Sparse cliques trump scale-free networks in coordination and competition

Cooperative behavior, a natural, pervasive and yet puzzling phenomenon, can be significantly enhanced by networks. Many studies have shown how global network characteristics affect cooperation; however, it is difficult to understand how this occurs based on global factors alone, low-level network building blocks, or motifs are necessary. In this work, we systematically alter the structure of sc...

An Efficient Strategy for Power Rating Reduction of Back-to-Back Converters Used in Railway Power Conditioner

One of the most common solutions to deal with the power quality issues of electrical railway systems is employing Railway Power Conditioner (RPC). In the conventional mode of operation, the RPC power rating deployed in every Traction Power Substation (TPS) is significantly large. This paper mainly focuses on the power rating reduction of RPC through presenting a novel combinatorial compensation...
