Testing deep placement of an 15N tracer as a method for in situ deep root phenotyping of wheat, barley and ryegrass

Plant Methods, 2019
Background Deep rooting is one of the most promising plant traits for improving crop yield under water-limited conditions. Most root phenotyping methods are designed for laboratory-grown plants, typically measuring very young plants not grown in soil and

Sampling Reconstruction of Stochastic Signals– The Roots in the Fifties

Austrian Journal of Statistics, 2016
In this article we are interested in the beginnings and the development of the sampling theory in signal analysis of stochastic signals, locating these in the early fifties. Besides the most important papers by Parzen (1956), Balakrishnan (1957), Belyaev (1959), and Lloyd (1959) we expose and report on few other interesting articles not widely known ...

Determination of the Suitable Location of Soil Moisture Sampling in Drip-Tape Irrigation Management in A Maize Field

علوم آب و خاک, 2019
Location of soil moisture sampling in irrigation management is of special importance due to the spatial variability of soil hydraulic characteristics and the development of root system.

Aeroponic approach for nondestructive root exudate collection and simulation of variable water stress trialed on cotton (Gossypium hirsutum)

Scientific Reports
Analyzing root exudates during drought poses a serious challenge; sampling root exudates in soil is destructive to roots and leads to biased molecular analysis, along with microbial decomposition and exudate sorption to soil components.

Bias in the Estimation of the Mean Reversion Parameter in Continuous Time Models [PDF]

It is well known that for continuous time models with a linear drift standard estimation methods yield biased estimators for the mean reversion parameter both in finite discrete samples and in large in-fill samples.

Between Two Extremes: Tripsacum dactyloides Root Anatomical Responses to Drought and Waterlogging

Plant Direct
Plant roots are the critical interface between plants, soil, and microorganisms, and respond dynamically to changes in water availability. Although anatomical adaptations of roots to water stress (e.g., the formation of root cortical aerenchyma) are well

Sampling random cycle-rooted spanning forests on infinite graphs

Electronic Journal of Probability
On a finite graph, there is a natural family of Boltzmann probability measures on cycle-rooted spanning forests, parametrized by weights on cycles. For a certain subclass of those weights, we construct Gibbs measures in infinite volume, as limits of probability measures on cycle-rooted spanning forests of increasing sequences of finite graphs.
