Remarks on the mutual singularity of multifractal measures

open access: yes, 2021
In the present work, we study the mutual singularity of multifractal Hausdorff and packing measures which provide a positive answer to Olsen’s questions in a more general framework.

Energy‐Associated Splitting Schemes for Closed Nonlinear Port‐Hamiltonian Systems

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT We present splitting methods for port‐Hamiltonian (pH) systems, focusing on the preservation of their internal structure, in particular, the dissipation inequality. Classical high‐order splitting schemes possess negative step sizes, which might cause instabilities and the violation of the dissipation inequality.

Divergence points of self-similar measures and packing dimension

open access: yes, 2007
Let μ be a self-similar measure in Rd. A point x∈Rd for which the limit limr↘0logμB(x,r)logr does not exist is called a divergence point. Very recently there has been an enormous interest in investigating the fractal structure of various sets of ...

Clinicopathological characteristics of patients with inoperable non‐small cell lung cancer harboring circulating NRF2 pathway mutations

open access: yesThe Journal of Pathology, Volume 269, Issue 2, Page 164-181, June 2026.
Abstract Lung cancer is the leading cause of global cancer‐related morbidity and mortality, with tobacco smoking as its strongest risk factor. Nuclear factor erythroid 2‐related factor 2 (NRF2) is a redox‐regulated transcription factor frequently dysregulated in non‐small cell lung cancer (NSCLC), leading to aggressive disease and resistance to therapy.

Packing measures and dimensions on cartesian products

open access: yes, 2021
Packing measures Pg(E) and Hewitt-Stromberg measures vg(E) and their relatives are investigated. It is shown, for instance, that for any metric spaces X, Y and any Hausdorff functions f, g vg (X) • Ph (Y) ≤ Pgh (X x Y).

Machine Learning for Local Detection of Separators in Three‐Dimensional Magnetic Fields

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Magnetic reconnection is a major plasma phenomenon occurring in various key environments ranging from the Sun and near‐Earth space to astrophysical plasmas. While magnetic reconnection is relatively well‐understood under two‐dimensional (2D) settings, it remains challenging to characterize in three‐dimensional (3D) magnetic fields.

Freezing of Gait in Parkinson's Disease: A Heterogeneous Phenomenon Across Assessment Tools

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 11, June 2026.
Freezing of gait in Parkinson's disease is a heterogeneous, context‐ and tool‐dependent phenomenon that may emerge in early disease. Capturing freezing requires multimethod assessment, and interpretation of freezing‐related outcomes should take into account disease severity.

Hausdorff dimension of fiber-coding sub-Sierpinski carpets

open access: yes, 2007
In this paper we study a class of subset of Sierpinski carpets for which the allowed digits in the expansions fall into each fiber set with a prescribed frequency.

On relations between entropy and Hausdorff dimension of measures

open access: yes, 2002
International audienceWe characterize probability measures whose Hausdorff dimension or packing dimension can be calculated by an entropy formula. In particular, we prove that such measures are unidimensional. We also construct examples of unidimensional

An Approach to Automatic Georeferencing of Single Architectural BIM Models Using Shape Geometry Matching of Footprints

open access: yesTransactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT The integration of Building Information Models (BIM) and Geospatial Information Systems (GIS) is important to designing and developing smart cities and digital twins. Although significant advancements have been achieved, challenges remain in georeferencing BIM models to integrate them into the geospatial environment.
