Semicopulae [PDF]

open access: yes, 2005
We define the notion of semicopula, a concept that has already appeared in the statistical literature and study the properties of semicopulas and the connexion of this notion with those of copula, quasi-copula, t ...

Searching for Universality of Turbulence in the Earth's Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Turbulence in space plasmas remains a fundamental challenge, and Earth's magnetosphere (MSP) offers a natural laboratory for its study. Using high‐resolution magnetic field data from the Magnetospheric Multiscale (MMS) mission, we extend a stochastic Markovian framework to analyze turbulence across 10 diverse magnetospheric regions, including ...

Anthropogenic Changes of Compound Extreme Precipitation Preconditioned by Heatwaves Have Emerged From the Internal Climate Variability in China

open access: yesEarth's Future, Volume 13, Issue 9, September 2025.
Abstract Compound extreme precipitation preconditioned by heatwaves (CHEPs) are attracting people's attention nowadays, due to their devastating impacts on ecosystems and society. Although previous studies have widely investigated the historical changes of CHEPs, when these changes emerge from the internal climate variability remains unclear.

Investigation on the Calibration of Numerical Models for Cast Steel Replaceable Modular Yielding Links in Steel Eccentrically Braced Frames

open access: yesEarthquake Engineering &Structural Dynamics, Volume 54, Issue 10, Page 2433-2452, August 2025.
ABSTRACT A new generation of yielding links, referred to as cast steel replaceable modular yielding links (CMLs), was recently validated through extensive large‐scale testing, to enhance the seismic performance of steel eccentrically braced frames (EBFs). The effective use of CMLs relies on accurately evaluating the seismic response of the EBF systems,

Improved Robust Price Bounds for Multi-Asset Derivatives under Market-Implied Dependence Information

open access: yes, 2022
We show how inter-asset dependence information derived from observed market prices of liquidly traded options can lead to improved model-free price bounds for multi-asset derivatives.

Discrete Imprecise Copulas [PDF]

open access: yes
In this paper, we study discrete quasi-copulas associated with imprecise copulas. We focus on discrete imprecise copulas that are in correspondence with the Alternating Sign Matrices and provide some construction techniques of dual pairs.

A primer on triangle functions II [PDF]

open access: yes, 2010
In [32] we presented an overview of concepts, facts and results on triangle functions based on the notions of t-norm, copula, (generalized) convolution, semicopula, quasi-copula. Here, we continue our presentation.
