We apply the polar decomposition of the Mueller matrix describing a liquid-crystal-on-silicon display to identify the diattenuator, depolarizer, and retarder contributions as a function of the gray level. The retarder contribution is expressed in terms of the equivalent Jones matrix to apply previous techniques to evaluate the phase modulation. This allows searching for optimized polarization c...

[1] Voyager measurements of the galactic proton and Helium nuclei spectra beyond the heliospheric termination shock and out to ∼110 AU seem to imply lower interstellar cosmic ray intensities of these nuclei than previously estimated. Using new interstellar spectra that are in much better agreement with these Voyager measurements we have calculated the production of Be in the Earth’s polar atmos...

we present observation of polar coronal hole plumes with foot point jets that shows evidence of longitudinal acceleration. the series of event, occurring in the north coronal hole on 10 july 2010, was observed by the aia telescopes of the solar dynamic observatory (sdo mission) in the euv lines, with unprecedented details. the structures along the plume show a propagating outward velocity of ab...

QIN, JIFENG. A Low Noise, High Efficiency Envelope Modulator Structure for EDGE Polar Modulation. (Under the direction of Dr. Alex Q. Huang). Dynamic supply of power amplifiers in wireless transmitters can overcome the linearity-efficiency tradeoff issue in power amplifiers design, and envelope modulator is the key block in the dynamic supply system, low noise and high efficiency implementation...

POLAR is a novel compact space-borne Compton polarimeter conceived for a precise measurement of hard X-ray polarization and optimized for the detection of the prompt emission of Gamma-Ray Bursts (GRB) in the energy range 50−500 keV. A first detailed measurement of the polarization from astrophysical sources will lead to a better understanding of the source geometry and of the emission mechanism...

The Polar fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5) is employed to examine the El Niño–Southern Oscillation (ENSO) modulation of Antarctic climate for July 1996–June 1999, which is shown to be stronger than for the mean modulation from 1979 to 1999 and appears to be largely due to an eastward shift and enhancement of convection in the tropical Pacific Ocean. This...
