Resonant mode coupling theory: Fifty years of progress in space plasma physics

Perspective: Fifty years of density-functional theory in chemical physics.

Since its formal inception in 1964-1965, Kohn-Sham density-functional theory (KS-DFT) has become the most popular electronic structure method in computational physics and chemistry. Its popularity stems from its beautifully simple conceptual framework and computational elegance. The rise of KS-DFT in chemical physics began in earnest in the mid 1980s, when crucial developments in its exchange-c...

+ Leprosy: Fifty Years of Progress

The first technical issue of the Boletin de la Oficina Sanitaria Panamericana, published in 1922, was dedicated to leprosy. During the intervening SO years considerable progress has been made in understanding the disease, leading to benefit for the patient and more effective control. Movement away from institutionalization and toward ambulatory care for patients plus new and effective treatment...

Fifty Years of Medical Progress, 1873-1922

Fifty Years of Shannon Theory

A brief chronicle is given of the historical development of the central problems in the theory of fundamental limits of data compression and reliable communication.

Congestive heart failure: fifty years of progress.

Volume 1 of Circulation provides an excellent snapshot of the understanding of the mechanisms and treatment of heart failure a half century ago. During that era, circulatory pathophysiology was at the center of investigative attention. For example, Tinsley Harrison and his group divided heart failure into “primary disorders of filling and primary disorders of emptying,”1 a forerunner of our cur...
