Asia is at a dangerous moment. China is rising fast. Young, reckless North Korean dictator Kim Jong-un is engaging in territorial spats with the US president over nuclear missiles. Japan's nationalist government is remilitarising, throwing off the constitutional constraints imposed at the end of World War II. Washington is charting a different course, too: Donald Trump is the first US president to have contact with Taiwanese leaders since the 1970s, and also the first to edge his finger so firmly towards the nuclear button over North Korea. The doomsday clock has reached two minutes to midnight, as the possibility of global catastrophe looms ever closer. In this revelatory analysis, strategic expert Brendan Taylor examines the four Asian flashpoints that are most likely to erupt in sudden and violent conflict: the Korean Peninsula, Taiwan, the South China Sea and the East China Sea. He argues that crisis can only be averted by understanding the dynamics of these global hotspots and the complex interrelations between them. Drawing on history, contemporary sources and in-depth reports to weave an analysis both pertinent and chilling, Taylor asks what the world's major powers can do to avoid an eruption of war -- and what role Australia, as both a force in this region and a historical ally of the United States, can play to change the course of this otherwise disastrous history.

The past two decades have seen remarkable advances in observations of sunspots and their magnetic fields, in imaging of spots and fields in distant stars and in associated theoretical models and numerical simulations. This book provides a comprehensive combined account of the properties of sunspots and starspots. It covers both observations and theory, and describes the intricate fine structure of a sunspot's magnetic field and the prevalence of polar spots on stars. The book includes a substantial historical introduction and treats solar and stellar magnetic activity, dynamo models of magnetic cycles, and the influence of solar variability on the Earth's magnetosphere and climate. This volume is a valuable reference for graduate students and specialists in solar and stellar physics, astronomers, geophysicists, space physicists and experts in fluid dynamics and plasma physics.

Organic photovoltaic is an attractive technology to solve future energy supply scenarios. To further increase the potential of this technology novel absorber materials and interface materials have to be developed. In this work the paramount importance of interface materials for efficient as well as stable organic photovoltaic cells and modules is demonstrated. The general requirements of interface materials are elaborated and properties of a novel interface material which meets the demands are investigated experimentally and by simulations.

"A history of the controversy over sunspots with translations of the letters contained in Galileo's Istoria e dimostrazioni intorno alle macchie solari e loro accidenti. The material that was added during the printing of the Istoria, the dedication, preface, laudatory poems, and the note from the printer to introduce Scheiner's tracts, have been added in an appendix"--

Johann Georg Locher wrote Disquisitiones Mathematicae (Mathematical Disquisitions) in 1614, about astronomy and the sun. Galileo replied, through Dialogue Concerning the Two Chief World Systems, Ptolemaic and Copernican, in 1632.
