Deep Underground Science and Engineering, EarlyView.The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Hölder differentiability of self-conformal devil's staircases [PDF]
, 2014 In this paper we consider the probability distribution function of a Gibbs measure supported on a self-conformal set given by an iterated function system (devil's staircase) applied to a compact subset of ℝ. We use thermodynamic multifractal formalism to

Higher Order Multifractal Analysis [PDF]
, 1996 Projet FRACTALESWe extend the multifractal analysis to the description of the distribution of the $n$-th order correlation of singularities. For this purpose, new multifractal spectra are defined, and some general relations between them are given.

Revisiting the multifractal analysis of measures
Revista Matemática Iberoamericana, 2013 New proofs of theorems on the multifractal formalism are given. They yield results even at points q for which Olsen’s functions b(q) and B(q) differ. Indeed, we provide an example

Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

Multivariate multifractal analysis [PDF]
, 2019 International audienceWe show how a joint multifractal analysis of a collection of signals unravels correlations between the locations of their pointwise singularities. The multivariate multifractal formalism, reformulated in the general setting supplied

ESC Heart Failure, Volume 12, Issue 2, Page 980-997, April 2025.Abstract Heart failure (HF) creates a considerable clinical, humanistic and economic burden on patients and caregivers as well as on healthcare systems. To attenuate the significant burden of HF, there is a need for enhanced management of patients with HF.

Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics
FlexMat, EarlyView.Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...

International Journal of Finance &Economics, EarlyView.ABSTRACT This study examines risk transmission and co‐movements between financial markets (G7 countries and China) and commodity markets (gold and oil) during the COVID‐19 crisis. Daily closing prices for major equity indices (CAC40, CSI300, DAX30, FTSE100, MIB, NIKKEI, TSX and S&P500) and futures prices for gold, brent and WTI were analysed using DCC ...
