Estimation of Net Ecosystem Carbon Exchange for the Conterminous United States by Combining MODIS and AmeriFlux Data
(Elsevier, 2008)
Eddy covariance flux towers provide continuous measurements of net ecosystem carbon exchange (NEE) for a wide range of climate and biome types. However, these measurements only represent the carbon fluxes at the scale of ...
Optimum-Weighted RLS Channel Estimation for Rapid Fading MIMO Channels
(Institute of Electrical and Electronics Engineers, 2008)
This paper investigates on an accurate channel estimation scheme for fast fading channels in multiple-input multiple-output (MIMO) mobile communications. A high-order exponential-weighted recursive least-squares (EW-RLS) ...
Fibronectin Unfolding Revisited: Modeling Cell Traction-Mediated Unfolding of the Tenth Type-III Repeat
(Public Library of Science, 2008)
Fibronectin polymerization is essential for the development and repair of the extracellular matrix. Consequently, deciphering the mechanism of fibronectin fibril formation is of immense interest. Fibronectin fibrillogenesis ...
Plasmonic Laser Antennas and Related Devices
(IEEE Photonics Society, 2008)
This paper reviews recent work on device applications of optical antennas. Localized surface plasmon resonances of gold nanorod antennas resting on a silica glass substrate were modeled by finite difference time-domain ...
Optical Information Processing in Bose-Einstein Condensates
(Nature Publishing Group, 2008)
Testing a Purportedly More Learnable Auction Mechanism
(Berkeley Mathemarketics Group, 2008)
We describe an auction mechanism in the class of Groves mechanisms that has received attention in the computer science literature because of its theoretical property of being more “learnable” than the standard second price ...
Enabling Environment Design via Active Indirect Elicitation
(2008)
Many situations arise in which an interested party wishes to
affect the decisions of an agent; e.g., a teacher that seeks to
promote particular study habits, a Web 2.0 site that seeks to
encourage users to contribute ...
Defect-Mediated Emulsification in Two Dimensions
(American Physical Society, 2008)
We consider two-dimensional dispersions of droplets of isotropic phase in a liquid with an XY-like order parameter, tilt, nematic, and hexatic symmetries being included. Strong anchoring boundary conditions are assumed. ...
Transpacific Transport of Ozone Pollution and the Effect of Recent Asian Emission Increases on Air Quality in North America: An Integrated Analysis Using Satellite, Aircraft, Ozonesonde, and Surface Observations
(Copernicus Publications, 2008)
We use an ensemble of aircraft, satellite, sonde, and surface observations for April–May 2006 (NASA/INTEX-B aircraft campaign) to better understand the mechanisms for transpacific ozone pollution and its implications for ...
New Constraints on Terrestrial and Oceanic Sources of Atmospheric Methanol
(Copernicus Publications, 2008)
We use a global 3-D chemical transport model (GEOS-Chem) to interpret new aircraft, surface, and oceanic observations of methanol in terms of the constraints that they place on the atmospheric methanol budget. Recent ...
