The accurate estimation of grain yield in rice breeding is crucial for breeders to screen and select qualified cultivars. In this study, a low-cost unmanned aerial vehicle (UAV) platform mounted with an RGB camera was carried out capture high-spatial resolution images canopy breeding. random forest (RF) regression techniques were used establish models by using (1) only color vegetation indices ...

[1] Clouds and the Earth’s radiant energy system (CERES) is a satellite-based remote sensing system designed to monitor the Earth’s radiation budget. In this paper we examine uncertainties in the angular distribution models (ADMs) used by CERES over permanently snow covered surfaces with clear skies. These ADMs are a key part of the CERES data processing algorithms, used to convert the observed...

importance of fresh water in agriculture along with the essential demand of the growing population for food, indicates an extreme necessity of the optimum use of water. to this end, plant growth simulation models have been introduced in agricultural sciences to reach maximum yields in varying climates. variations in the of developed models cause difficulties for the unprofessional users. the aq...

in this study, a complex crop model was developed that integrates the various components of swap and csm-ceres-maize (dssat v4.0) model with the purpose of developing a more efficient model and according to the internal requirements. in the hybrid model, ceres-maize supplies swap model with daily leaf area index and root depth and on the other hand swap model supplies ceres-maize with daily wea...

A large number of perturbed-physics simulations of the HadAM3 atmospheric model were compared with the CERES (Clouds and Earth’s Radiant Energy System) estimates of Outgoing Longwave Radiation (OLR) and Reflected Shortwave Radiation (RSR) as well as OLR and RSR from the earlier ERBE (Earth Radiation Budget Experiment) estimates. The model configurations were produced from several independent op...

MOTIVATION There is accumulating evidence that the chromatin environment of transcription factor (TF) binding sites in promoter regions has a critical influence on their regulatory potential. Recent studies have mapped TF binding sites and nucleosome positions throughout the yeast genome; however, there is a lack of computation tools to integrate these data types. RESULTS We have developed th...

Observations and models of Ceres suggest that its evolution was shaped by interactions between liquid water and silicate rock. Hydrothermal processes in a heated core require both fractured rock and liquid. Using a new core cracking model coupled to a thermal evolution code, we find volumes of fractured rock always large enough for significant interaction to occur. Therefore, liquid persistence...

Introduction: We consider Ceres as a prototype for planetary evolution [1]. From thermal modeling by McCord and Sotin [2, 3, 4], Ceres was inferred to have differentiated into a rocky core of hydrated silicates, and an icy outer shell. Thomas et al. [5] confirmed such a model from direct observation of Ceres’s shape from Hubble Space Telescope observations, and pervious occultation measurements...
