On the distribution on the roots of polynomials [PDF]

open access: yesAnnales de l'Institut Fourier, 1996
Using classical results on conjugate functions, we give very short proofs of theorems of Erdös–Turán and Blatt concerning the angular distribution of the roots of polynomials. Then we study some examples.

Probability Distribution on Full Rooted Trees [PDF]

open access: yesEntropy, 2022
The recursive and hierarchical structure of full rooted trees is applicable to statistical models in various fields, such as data compression, image processing, and machine learning. In most of these cases, the full rooted tree is not a random variable; as such, model selection to avoid overfitting is problematic. One method to solve this problem is to

A sonic root detector for revealing tree coarse root distribution. [PDF]

open access: yesSci Rep, 2020
AbstractThis study assesses the reliability of a non-destructive method for determining the in situ distribution of tree coarse roots within a scaled distance 6-fold the DBH by comparing the results with the actual 3D root architecture revealed by invasive methods. The root architecture of 22-year-old olive trees was determined non-destructively with a

Dry Season Transpiration and Soil Water Dynamics in the Central Amazon

open access: yesFrontiers in Plant Science, 2022
With current observations and future projections of more intense and frequent droughts in the tropics, understanding the impact that extensive dry periods may have on tree and ecosystem-level transpiration and concurrent carbon uptake has become ...

Nitrogen Fertilization Increases Root Growth and Coordinates the Root–Shoot Relationship in Cotton

open access: yesFrontiers in Plant Science, 2020
The root system plays an important role in the growth and development of cotton, and root growth is closely related to shoot growth, both of which are affected by N availability in the soil.

Effects of root morphology on stress distribution at the root apex [PDF]

open access: yesThe European Journal of Orthodontics, 2007
It is thought that the stress concentration at the root apex caused by orthodontic force induces root resorption. The purpose of this study was to investigate stress distribution at the root in cases of deviated root shapes using finite element models (FEMs).

Field traffic-induced soil compaction under moderate machine-field conditions affects soil properties and maize yield on sandy loam soil

open access: yesFrontiers in Plant Science, 2023
Soil compaction due to field trafficking involves a complex interplay of machine-soil properties. In contrast to previous studies simulating worst field scenarios, this two-year field experiment investigated the effects of traffic-induced compaction ...

Response of young 'Tahiti' lime trees to different irrigation levels Resposta de plantas jovens de limeira-ácida 'Tahiti' a diferentes níveis de irrigação

open access: yesEngenharia Agrícola, 2011
The aim of this study was to evaluate the effect of different irrigation levels on canopy and root growth, productivity, and fruit quality of young ‘Tahiti’ acid lime trees. The experiment was installed in Piracicaba, Brazil in a 1.0-ha orchard plot with

Varietal Differences in the Root Systems of Rice (Oryza sativa L.) under Drip Irrigation with Plastic Film Mulch

open access: yesAgronomy, 2023
With the escalating water scarcity in agriculture, a novel water-saving technique has emerged: drip irrigation with plastic film mulch (DI). Root function is crucial for sustaining rice production, and understanding its response to DI is essential ...
