The search for quantum critical scaling in a classical system
(American Institute of Physics, 2009)
Order-disorder phase transitions in magnetic metals that occur at zero temperature have been studied in great detail. Theorists have advanced scenarios for these quantum critical systems in which the unusual response can ...
Magnetic ordering in the spinel compound Li[Mn2-xLix]O4(x=0,0.04)
(American Institute of Physics, 2009)
The two B-site ions Mn3+ and Mn4+ in the stoichiometric spinel structure LiMn2O4 form a complex, columnar ordered pattern below the charge-ordering transition at room temperature. On further cooling to below 66 K, the ...
Sub-2 nm Size-Tunable High-Density Pt Nanoparticle Embedded Nonvolatile Memory
(Institute of Electrical and Electronics Engineers, 2009-12)
The charge-storage characteristics of a metal-oxide-semiconductor (MOS) structure containing size-tunable sub-2 nm Pt nanoparticles (NPs) between Al2O3 tunneling and capping oxide layers were studied. Significantly different ...
Formal framework for a nonlocal generalization of Einstein's theory of gravitation
(American Physical Society, 2009)
The analogy between electrodynamics and the translational gauge theory of gravity is employed in this paper to develop an ansatz for a nonlocal generalization of Einstein's theory of gravitation. Working in the linear ...
Entropy driven spontaneous formation of highly porous films from polymer-nanoparticle composites
(Institute of Physics, 2009)
Nanoporous materials have become indispensable in many fields ranging from photonics, catalysis and semiconductor processing to biosensor infrastructure. Rapid and energy efficient process fabrication of these materials ...
Optics of rotating systems
(American Physical Society, 2009)
Electrodynamics of rotating systems is expected to exhibit novel nonlocal features that come about when acceleration-induced nonlocality is introduced into the special relativity theory in conformity with the Bohr-Rosenfeld ...
Nonlocal Transformations for Accelerated Observers
(arXiv, 2009)
According to the locality postulate of special relativity, the measurements of physical fields by accelerated observers at a given event in Minkowski spacetime are related to each other by the representations of the Lorentz ...
Subdiffusion and lateral diffusion coefficient of lipid atoms and molecules in phospholipid bilayers
(American Physical Society, 2009)
We use a long, all-atom molecular-dynamics MD simulation combined with theoretical modeling to investigate the dynamics of selected lipid atoms and lipid molecules in a hydrated diyristoyl-phosphatidylcholine
lipid ...
Using stochastic models calibrated from nanosecond nonequilibrium simulations to approximate mesoscale information
(American Institute of Physics, 2009)
We demonstrate how the surrogate process approximation (SPA) method can be used to compute both the potential of mean force along a reaction coordinate and the associated diffusion coefficient using a relatively small ...
Harvesting triplet excitons for application in polymer solar cells
(American Institute of Physics, 2009)
Triplet enhanced ladder-type poly (para-phenylene) polymer (PhLPPP) with covalently bound trace amounts of palladium blended with a fullerene derivative [[6,6]-phenyl C61-butyric acid methyl ester (PCBM)] shows power ...
Characteristics of Herbicides and Weed-Management Programs Most Important to Corn, Cotton, and Soybean Growers
(AgBioForum, 2009)
The introduction and rapid adoption of herbicide-tolerant crops has renewed interest in better understanding the characteristics of herbicides and weed-management programs that are important to growers besides profitability. ...
Glyphosate-Resistant Crops and Weeds : Now and in the Future
(AgBioForum, 2009)
Glyphosate-resistant (GR) crops represent more than 80% of the 120 million ha of transgenic crops grown annually worldwide. GR crops have been rapidly adopted in soybean, maize, cotton, canola, and sugarbeet in large part ...
Effects of Weed-Resistance Concerns and Resistance-Management Practices on the Value of Roundup Ready[trademark] Crops
(AgBioForum, 2009)
This study estimates grower benefits of Roundup-Ready[trademark] (RR) weed management programs and how weed-resistance concerns and resistance-management practices affect those benefits. Direct survey methods were used to ...
Stakeholder Positions Toward GM Food : the Case of Vitamin A Biofortified Cassava in Brazil
(AgBioForum, 2009)
This article examines the factors that affect stakeholders' positions toward genetically modified (GM) crops in Brazil, both in general and in the case of GM cassava in particular. Perceptions about the benefits of ...
Perceived Consequences of Herbicide-Tolerant and Insect-Resistant Crops on Integrated Pest Management Strategies in the Western United States : Results of an Online Survey
(AgBioForum, 2009)
We conducted an online survey to assess the potential effects of herbicide-tolerant (HT) and insect-resistant (IR) crops on integrated pest management (IPM) practices in the Western United States For HT crops, participants ...
Predicted Willingness of Irish Farmers to Adopt GM Technology
