TL;DR: In this paper, the potential grain yield of winter wheat (Triticum aestivum L) was predicted using in-season spectral measurements collected between January and March, where the normalized difference vegetation index (NDVI) was determined from reflectance measurements under daytime lighting in the red and near-infrared (NIR) regions of the spectra.
Abstract: Nitrogen fertilization rates in cereal production systems are generally determined by subtracting soil test N from a specified N requirement based on the grain yield goal, which represents the best achievable grain yield in the last 4 to 5 yr. If grain yield could be predicted in season, topdress N rates could be adjusted based on projected N removal. Our study was conducted to determine if the potential grain yield of winter wheat (Triticum aestivum L.) could be predicted using in-season spectral measurements collected between January and March. The normalized difference vegetation index (NDVI) was determined from reflectance measurements under daytime lighting in the red and near-infrared (NIR) regions of the spectra. In-season estimated yield (EY) was computed using the sum of two postdormancy NDVI measurements (Jan. and Mar.) divided by the cumulative growing degree days (GDD) from the first to second reading. A significant relationship between grain yield and EY was observed (R 2 = 0.50, P > 0.0001) when combining all nine locations across a 2-yr period. Our estimates of potential grain yield (made in early Mar.) differed from measured grain yield (mid-July) at three sites where yield-altering factors (e.g., late summer rains delayed harvest and increased grain yield loss due to lodging and shattering) were encountered after the final sensing. Evaluating data from six of the nine locations across a 2-yr period, EY values explained 83% of the variability in measured grain yield. Use of EY may assist in refining in-season application of fertilizer N based on predicted potential grain yield.

Journal ArticleDOI
TL;DR: The Oklahoma Mesonet as mentioned in this paper is a multipurpose network with more than 110 surface observing stations that send data every 5 min to an operations center for data quality assurance, product generation, and dissemination.
Abstract: Established as a multipurpose network, the Oklahoma Mesonet operates more than 110 surface observing stations that send data every 5 min to an operations center for data quality assurance, product generation, and dissemination. Quality-assured data are available within 5 min of the observation time. Since 1994, the Oklahoma Mesonet has collected 3.5 billion weather and soil observations and produced millions of decision-making products for its customers.

TL;DR: Evidence is provided that tick bites are a cause, possibly the only cause, of IgE specific for alpha-gal in this area of the United States, and the first example of a response to an ectoparasite giving rise to an important form of food allergy is reported.
Abstract: Background: In 2009, we reported a novel form of delayed anaphylaxis to red meat that is related to serum IgE antibodies to the oligosaccharide galactose-alpha-1,3-galactose (alpha-gal). Most of th ...

TL;DR: In this article, a cancellation of absorption occurs on resonance for two (or any even number of) coupled optical resonators, due to mode splitting and classical destructive interference, particularly when the resonator finesse is large and the loss in resonator farthest from the excitation waveguide is small.
Abstract: We demonstrate that a cancellation of absorption occurs on resonance for two (or any even number of) coupled optical resonators, due to mode splitting and classical destructive interference, particularly when the resonator finesse is large and the loss in the resonator farthest from the excitation waveguide is small. The linewidth and group velocity of a collection of such coupled-resonator structures may be decreased by using larger resonators of equal size, by using larger resonators of unequal size where the optical path length of the larger resonator is an integer multiple of that of the smaller one, or by using a larger number of resonators per structure. We explore the analogy between these effects and electromagnetically-induced transparency in an atomic system.

Journal ArticleDOI
TL;DR: In this article, a study based on a long-term manipulation experiment in a grassland ecosystem describes the microbial mechanisms controlling feedbacks to carbon and nutrient cycling under warming, and suggests that ecosystem models should more explicitly consider microbial feedbacks.
Abstract: A study based on a long-term manipulation experiment in a grassland ecosystem describes the microbial mechanisms controlling feedbacks to carbon and nutrient cycling under warming. The findings suggest that ecosystem models should more explicitly consider microbial feedbacks to climate change.
