In spite of recent economic growth, India is
a country with serious deficits in its power sector. Four hundred million Indians lack access to
electricity, blackouts have become front-page
news, and...

Modern scientific technology has provided a new class of large-scale simultaneous inference
problems, with thousands of hypothesis tests to consider at the same time. Microarrays epitomize this...
Power counting of loop diagrams in general relativity
Cyclic graph the general theory of relativity energy expansion quantum effects physical power calculation

2013/7/3
We investigate the spatial coherence of the light generated from high-power multi-chip red LEDs by using the van Cittert-Zernike theorem. It is theoretically demonstrated that the light generated from...
Ultrasolitons: multistability and subcritical power threshold from higher-order Kerr terms
Ultrasolitons multistability and subcritical power threshold higher-order Kerr terms Pattern Formation and Solitons
font style='font-size:12px;'>
2012/4/27
We show that an optical system involving competing higher-order Kerr nonlinearities can support the existence of ultrasolitons, namely extremely localized modes that only appear above a certain thresh...
