Short and Long Range Population Dynamics of the Monarch [PDF]
arXiv, 2011 The monarch butterfly annually migrates from central Mexico to southern Canada. During recent decades, its population has been reduced due to human interaction with their habitat. We examine the effect of herbicide usage on the monarch butterfly's population by creating a system of linear and non-linear ordinary differential equations that describe the

Voltammetric Determination of Paraquat Using Graphite Pencil Electrode Modified with Doped Polypyrrole [PDF]
arXiv, 2016 Recognition and determination of paraquat (PQ) using graphite pencil electrode (GPE) modified with polypyrrole (Ppy) doped with Eriochrome blue-black B (EBB) is reported. To that end, a thin film of Ppy was deposited onto the electrode surface by electropolymerization in the presence of a functional doping ion, EBB.

Marginalization in nonlinear mixed-effects models with an application to dose-response analysis [PDF]
arXiv, 2017 Inference in hierarchical nonlinear models needs careful consideration about targeting parameters that have either a conditional or population-average interpretation. For the special case of mixed-effects nonlinear sigmoidal models we propose a method for the estimation of derived parameters with a marginal interpretation, but also maintaining the ...

Real-time Semantic Segmentation of Crop and Weed for Precision Agriculture Robots Leveraging Background Knowledge in CNNs [PDF]
arXiv, 2017 Precision farming robots, which target to reduce the amount of herbicides that need to be brought out in the fields, must have the ability to identify crops and weeds in real time to trigger weeding actions. In this paper, we address the problem of CNN-based semantic segmentation of crop fields separating sugar beet plants, weeds, and background solely

Heliyon, 2023 Biodegradation studies of herbicides applied to the soil alone and in a mixture are required since herbicides are often used in combinations to control weeds. When herbicides are applied in mixtures, interactions may affect their environmental fate. Thus,

BRTSim, a general-purpose computational solver for hydrological, biogeochemical, and ecosystem dynamics [PDF]
arXiv, 2019 This paper introduces the recent release v3.1a of BRTSim (BioReactive Transport Simulator), a general-purpose multiphase and multi-species liquid, gas and heat flow solver for reaction-advection-dispersion processes in porous and non-porous media with application in hydrology and biogeochemistry.
