Overexpression of the Transcription Factor GROWTH-REGULATING FACTOR5 Improves Transformation of Dicot and Monocot Species

open access: yesFrontiers in Plant Science, 2020
Successful regeneration of genetically modified plants from cell culture is highly dependent on the species, genotype, and tissue-type being targeted for transformation. Studies in some plant species have shown that when expression is altered, some genes

On the association of sum- and max-stable processes [PDF]

open access: yesStatistics & Probability Letters, 2010
We address the notion of association of sum- and max- stable processes from the perspective of linear and max-linear isometries. We establish the appealing results that these two classes of isometries can be identified on a proper space (the extended positive ratio space).

Non-Stationary Dependence Structures for Spatial Extremes [PDF]

open access: yes, 2016
Max-stable processes are natural models for spatial extremes because they provide suitable asymptotic approximations to the distribution of maxima of random fields. In the recent past, several parametric families of stationary max-stable models have been

Spatial modeling of extreme temperature in the Canadian Prairies using max-stable processes

open access: yesResults in Engineering
The Prairie region of Canada is an agriculture-intensive area and is strategic to Canada's food security. Moisture deficit due to extreme temperatures leading to high evapotranspiration can have significant impacts on water availability, resulting in ...

Modelling of Packed Co Nanorods for Hard Magnetic Applications

open access: yesEPJ Web of Conferences, 2014
We present a numerical algorithm based on the bullet physics library to generate densely packed (39% - 41%) structures of high-aspect-ratio nanorods for finite element micromagnetic simulations.

Statistical Modeling of Spatial Extremes [PDF]

open access: yes, 2012
The areal modeling of the extremes of a natural process such as rainfall or temperature is important in environmental statistics; for example, understanding extreme areal rainfall is crucial in flood protection.

Approximation of Supremum of Max-Stable Stationary Processes & Pickands Constants [PDF]

open access: yesJournal of Theoretical Probability, 2019
Let $X(t),t\in \mathbb{R}$ be a stochastically continuous stationary max-stable process with Fr chet marginals $ _ , >0$ and set $M_X(T)=\sup_{t \in [0,T]} X(t),T>0$. In the light of the seminal articles [1,2], it follows that $A_T=M_X(T)/T^{1/ }$ converges in distribution as $T\to \infty$ to $\mathcal{H}_Z^{1/ } X(1)$, where $\mathcal{H ...

Modeling of spatial extremes in environmental data science: time to move away from max-stable processes

open access: yesEnvironmental Data Science
Environmental data science for spatial extremes has traditionally relied heavily on max-stable processes. Even though the popularity of these models has perhaps peaked with statisticians, they are still perceived and considered as the “state of the art ...
