Restoring the density-gradient expansion for exchange in solids and surfaces.

J. Perdew, A. Ruzsinszky, G. Csonka et al.

Popular modern generalized gradient approximations are biased toward the description of free-atom energies. Restoration of the first-principles gradient expansion for exchange over a wide range of density gradients eliminates this bias. We introduce a revised Perdew-Burke-Ernzerhof generalized gradient approximation that improves equilibrium properties of densely packed solids and their surfaces.

Fluid mechanics

Huy Q. Nguyen

The author discusses some basic questions in fluid dynamics. He describes Newton's contribution to fluid dynamics in the second volume of the Principia. He presents a brief review of fluid dynamics since Newton, and discusses the nature and content of physics curricula in schools and universities. He also outlines some aspects of modern research.

Political Order in Changing Societies

S. Huntington

This now-classic examination of the development of viable political institutions in emerging nations is a major and enduring contribution to modern political analysis. In a new Foreword, Francis Fukuyama assesses Huntington's achievement, examining the context of the book's original publication as well as its lasting importance. "This pioneering volume, examining as it does the relation between development and stability, is an interesting and exciting addition to the literature."--American Political Science Review "'Must' reading for all those interested in comparative politics or in the study of development."--Dankwart A. Rustow, Journal of International Affairs
