open access: yes, 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.

A metaphor for epidemiology: The sea of person time

open access: yesGlobal Epidemiology, 2021
Metaphors have had an important role to play in the theory and practice of epidemiology. Some well-known examples include “black boxes,” the “web of causation,” “shoe-leather epidemiology,” the “ivory tower” and the ubiquitous “gold standard.” Metaphors ...

The dual allelopathic capacity of two Brassicaceae plants’ seed powder in controlling Orobanche crenata infesting Pisum sativum as well as stimulating its growth and yield

open access: yesBulletin of the National Research Centre, 2020
Background It is well known that legume and other crops such as pea, faba bean, lentil, chick pea, and several other crops are susceptible to Orobanche crenata (broomrape) infestation. There is a direct relationship between O.

Laser weeding of common weed species [PDF]

open access: yesFrontiers in Plant Science
The massive use of herbicides since the 1950s has resulted in increasing problems with herbicideresistant weeds and pollution of the environment, including food, feed, and water. These side effects have resulted in political pressures to reduce herbicide application.

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

open access: yesPlants, 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 ...
