Effectiveness of Sowing Methods and Certain Herbicides against Dodder and Aannual Weeds Associated with Flax [PDF]
Egyptian Journal of Agricultural Sciences, 2022 Two field experiments were conducted during 2019/20 and 2020/21 seasons, to evaluate the influence of two sowing methods (broadcasting and drilling) and nine herbicides on dodder (Cuscuta epilinum), annual weeds and the productivity of flax (Linum ...

Entropic optimal transport is maximum-likelihood deconvolution [PDF]
, 2018 We give a statistical interpretation of entropic optimal transport by showing that performing maximum-likelihood estimation for Gaussian deconvolution corresponds to calculating a projection with respect to the entropic optimal transport distance.

The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]
, 2020 There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

The Parts Are Greater Than the Whole: How Securitization of Divisible Interests Can Revolutionize Structured Finance and Open the Capital Markets to Middle-Market Companies [PDF]
, 1993 We evaluated whether new information could be drawn from additional data collection and unconventional statistical analyses of an on-farm trial. First, we compared a conventional sampling method using a biomass estimate of weed abundance to repeated ...

Spatial and temporal stability of weed patches in cereal fields under direct drilling and harrow tillage [PDF]
, 2020 The adoption of conservation agriculture (CA) techniques by farmers is changing the dynamics of weed communities in cereal fields and so potentially their spatial distribution.

INFLUENCE OF INTER- AND INTRASPECIFIC COMPETITION BETWEEN MAIZE AND COMMON COCKLEBUR (Xanthium strumarium) WEED DENSITIES ON MAIZE PRODUCTIVITY [PDF]
Journal of Plant Production, 2016 Common cocklebur is considered a strong weed competitor to maize and distributed all over the world and Egypt. Knowledge about the nature of competition to maize is the key of planning weed management crop strategies in this crop.

Effect of Preceding Winter Crops and Herbicidal Combinations on Weeds, Yield and Econemic Feasability of Broadcast-Seeded Rice Productivity. [PDF]
Journal of Plant Production, 2016 Nowadays, in Egypt there is a big shift towards increasing the cultivated area with broadcast-seeded rice which needs to overcome the heavy out weeds infestation in this case.

Uncoupled isotonic regression via minimum Wasserstein deconvolution
, 2019 Isotonic regression is a standard problem in shape-constrained estimation where the goal is to estimate an unknown nondecreasing regression function $f$ from independent pairs $(x_i, y_i)$ where $\mathbb{E}[y_i]=f(x_i), i=1, \ldots n$. While this problem
