The Role of Learning Progressions in Standards-Based Education Reform written by Frederic A. Mosher, summarizes findings from two reports examining the concepts of learning progressions and learning trajectories as they are being applied in science and mathematics education. This policy brief reviews conclusions from the two extensive reports and discusses the implications of their findings for...

Mohs surgery is considered ideal treatment for many types of skin cancers. Developed by Dr Frederic Edward Mohs (1910-2002), Mohs surgery allows all surgical margins to be viewed microscopically, ensuring no cancer cells go unremoved, yet it failed to achieve immediate acceptance when first introduced in the 1940s. A catalyst to the widespread acceptance of Mohs surgery occurred with the work o...

The impact of optical feedback on the direct performance of a monolithic InAs/GaAs quantum dot passively mode-locked laser intended for applications such as multi-gigahertz interchip/intra-chip clock distribution is experimentally investigated. Evaluation of the feedback resistance is an important feature, as the laser is to be monolithically integrated on chip with other devices, in which case...
