In this Roentgen centennial year, honoring the epochal discovery of the X-ray in 1895 [2], it is particularly appropriate to reflect on the circumstances of creativity that lead to important discoveries in science. In radiolc , as in gen. . . . ne and surgery, histories of the development of the discipline have generally presented a chronicle of sequential events without specific consideration ...

Shocked by what he considered to be the savagery he encountered in Tierra del Fuego, Charles Darwin ranked the Fuegians lowest among the human races. An enduring story has it, however, that Darwin was later so impressed by the successes of missionaries there, and by the grandeur they discovered in the native tongue, that he changed his mind. This story has served diverse interests, religious an...

Inspired by the reduced basis approach and modern numerical multiscale methods, we present a new framework for an efficient treatment of heterogeneous multiscale problems. The new approach is based on the idea of considering heterogeneous multiscale problems as parametrized partial differential equations where the parameters are smooth functions. We then construct, in an offline phase, a suitab...

Surprisingly, to the eyes of many experts, the draft of DSM‐5 better captures the essence of narcissistic personality disorder (NPD) than previous versions did. Many clinicians (myself included) were dissatisfied with the descriptions of NPD in earlier versions of DSM. Persons with NPD are aggressive and boastful, overrate their performance, and blame others for their setbacks; current editions...

Monitoring évapotranspiration (ET) at large scales is important for assessing climate and anthropogenic effects on natural and agricultural ecosystems. This paper describes techniques used in evaluating ET with remote sensing, which is the only technology that can efficiently and economically provide regional and global coverage. Some of the empirical/statistical techniques have been used opera...
