Improved performance of a hybrid radio/fiber system using a directly modulated laser transmitter with external injection [PDF]

open access: yes, 2002
A directly modulated laser diode with external light injection is used to generate microwave optical signals for a hybrid radio/fiber system. The external light injection greatly enhances the frequency response of the laser, and thus, significantly ...

Development and design of binder systems for titanium metal injection molding: An overview

open access: yes, 2013
Titanium metal injection molding (Ti-MIM) has been practiced since the late 1980s. Logically, the Ti-MIM practice follows the similar processes developed for the antecedent materials such as stainless steel and ceramics.

Evidence and information for national injection safety policies [PDF]

open access: yes, 2003
The adverse consequences of poor injection practices have been reported for a few decades. However, key elements of evidence and information were lacking to allow decision-makers to formulate policies for the safe and appropriate use of injections.

Injective Envelopes of Operator Systems

open access: yesPublications of the Research Institute for Mathematical Sciences, 1979
We show the existence and uniqueness of a minimal injective operator system (resp. minimal unital C *-algebra) "containing" a given operator system. V , which will be called the injective (resp. C *-) envelope of
