Thanks Colin for comprehensive report. At last its good to see some fellows in gov. gets action, however i dont see anything for short term. japan had agreements with Kazakh, Vietnam and Mongols to secure mining rights for rare earths. What about US? Only a warn-report ?

More good/bad news for the industry here. With the increasing importance of rare earths, any scarcity will be a problem for some segment of the industry. Hopefully we can get through with minimal disruptions until the supply reaches the point where it is adequate.

R_Colin_Johnson: one thing I would conclude from the report (thanks for sharing it!) is that it is screaming for recycling and re-use! I am not sure if it is at all possible to find globally diverse supplies for some of these precious metals. Find the appropriate substitutes is where innovation can help. For the vast growth in smart (using Haptics) appliances that the industry pundits are happily predicting(!), this is a dire necessity. You simply can not depend on one country's (read: China!) natural resources to serve the whole world's needs. The report has a tonne of information for the supply chain managers to worry about in 2011! Dr. MP Divakar

Anyone concerned about rare earth scarcity should read this 172 page report, which is very comprehensive. The Critical Materials Strategy includes predictions about just how scarce each of the rare earths will become, for how long and with what specific results for business. In 2011, the report promises an even more comprehensive analysis of specific steps that need to be taken in order to insure an uninterrupted supply chain going forward.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
