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

Biochar‐Iron Oxide Composites for Adsorption of Chlorophenoxy Herbicides: Impact of Chlorine Substituents on Bath and Continuous Adsorption Performance

Advanced Sustainable Systems, EarlyView.
Iron oxide‐impregnated biochar from sugarcane bagasse exhibits remarkable efficiency in removing 2,4‐dichlorophenoxyacetic acid and chlorophenoxyacetic acid, offering a sustainable option for water purification. The material retains high performance under real conditions while meeting safety criteria for irrigation use. Distinct structural features and

Smart Harrowing—Adjusting the Treatment Intensity Based on Machine Vision to Achieve a Uniform Weed Control Selectivity under Heterogeneous Field Conditions

Agronomy, 2020
Harrowing is mostly applied with a constant intensity across the whole field. Heterogeneous field conditions such as variable soil texture, different crop growth stages, variations of the weed infestation level, and weed species composition are usually ...

Transgene Was Silenced in Hybrids between Transgenic Herbicide-Resistant Crops and Their Wild Relatives Utilizing Alien Chromosomes

Plants, 2022
The commercialization of transgenic herbicide-resistant (HR) crops may cause gene flow risk. If a transgene in progenies of transgenic crops and wild relatives is silencing, these progenies should be killed by the target herbicide, thus, the gene flow ...

Tolerance to weed harrowing in spring barley genotypes [PDF]

, 2005
Controlling weeds in spring cereals grown under organic conditions is mostly done by post emergence weed harrowing, where spring tines of the weed harrow control weeds by uprooting and/or covering small weeds plants with soil.

The Potential of Cognitive‐Inspired Neural Network Modeling Framework for Computer Vision

Advanced Science, EarlyView.
In article number 202507730, Guorun Li, Lei Liu, Yuefeng Du, and co‐workers present a cognitive modeling framework (CMF) to bridge the ‘representation gap’ and ‘conceptual gap’ between cognitive theory and vision deep neural networks (VDNNs). The research findings provide new insights and solid theoretical support for VDNN modeling inspired by ...
