A characterization of the normal distribution using stationary max-stable processes

open access: yes, 2015
Consider the max-stable process $\eta(t) = \max_{i\in\mathbb N} U_i \rm{e}^{\langle X_i, t\rangle - \kappa(t)}$, $t\in\mathbb{R}^d$, where $\{U_i, i\in\mathbb{N}\}$ are points of the Poisson process with intensity $u^{-2}\rm{d} u$ on $(0,\infty)$, $X_i$,

Validating and Developing Hyperspectral Indices for Tracing Leaf Chlorophyll Fluorescence Parameters under Varying Light Conditions

open access: yesRemote Sensing, 2023
Chlorophyll a fluorescence (ChlFa) parameters provide insight into the physiological and biochemical processes of plants and have been widely applied to monitor and evaluate the photochemical process and photosynthetic capacity of plants in a variety of ...

Efficient simulation of Brown-Resnick processes based on variance reduction of Gaussian processes [PDF]

open access: yes, 2018
Brown-Resnick processes are max-stable processes that are associated to Gaussian processes. Their simulation is often based on the corresponding spectral representation which is not unique.

Spatial risk measures for max-stable and max-mixture processes [PDF]

open access: yesStochastics, 2019
In this paper, we consider isotropic and stationary max-stable, inverse max-stable and max-mixture processes $X=(X(s))\_{s\in\bR^2}$ and the damage function $\cD\_X^ = |X|^ $ with ...

Testing the key processes that accelerate outer radiation belt relativistic electrons during geomagnetic storms

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Since the discovery of the Earth’s radiation belts in 1958, it has always been a challenge to determine the dominant physical mechanisms, whether local acceleration by chorus or inward radial diffusion, that leads to outer radiation belt relativistic ...

Conditional Sampling for Max-Stable Processes with a Mixed Moving Maxima Representation

open access: yes, 2014
This paper deals with the question of conditional sampling and prediction for the class of stationary max-stable processes which allow for a mixed moving maxima representation.

On the occurrence times of componentwise maxima and bias in likelihood inference for multivariate max-stable distributions [PDF]

open access: yes, 2015
Full likelihood-based inference for high-dimensional multivariate extreme value distributions, or max-stable processes, is feasible when incorporating occurrence times of the maxima; without this information, $d$-dimensional likelihood inference is ...

Ocean biogeochemistry in the warm climate of the late Paleocene [PDF]

open access: yesClimate of the Past, 2015
The late Paleocene is characterized by warm and stable climatic conditions that served as the background climate for the Paleocene–Eocene Thermal Maximum (PETM, ~55 million years ago).

Geometric ergodicity for some space-time max-stable Markov chains

open access: yes, 2018
Max-stable processes are central models for spatial extremes. In this paper, we focus on some space-time max-stable models introduced in Embrechts et al. (2016).

Coexistence of reward and unsupervised learning during the operant conditioning of neural firing rates.

open access: yesPLoS ONE, 2014
A fundamental goal of neuroscience is to understand how cognitive processes, such as operant conditioning, are performed by the brain. Typical and well studied examples of operant conditioning, in which the firing rates of individual cortical neurons in ...
