Hausdorff measures in topological spaces

open access: yes, 1965
Given a non-negative set function τ on a family ɑ of subsets of a metric space X, an outer measure ν can be generated on X as follows: for B⊂X and δ > 0, [Equations omitted] The Hausdorff s-dimensional and h-measures are special cases of this measure.

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.

Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.

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.

FILOMAT 17 (2003), 15–21 TWO WAYS TO COMPACTNESS

open access: yes, 2014
. In this paper we give two different ways of proving the compactness of some linear operators between certain sequence spaces. One of them is based only on the theory of matrix transformations and the other uses the Hausdorff measure of noncompactness ...

Experiences of Anxiety and Its Relationship to Freezing of Gait in Parkinson's Disease: A Qualitative Study

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Proposed framework depicting how anxiety, FOG, and walking confidence are interrelated. ABSTRACT Freezing of gait (FOG) is a disabling motor symptom in Parkinson's disease (PD) with substantial impact on mobility and quality of life. Anxiety is frequently implicated in triggering or worsening FOG, yet the lived experience of this interaction remains ...

Vector Measures Without Weak Compactness

open access: yes, 2010
The title above refers to a 1955 paper of Bartle, Dunford, and Schwartz \u27Weak Compactness and Vector Measures\u27 in which integration of scalar functions with respect to a vector measure was first defined.

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.

Multiplicity of nonnegative solutions for semilinear Robin problems involving sign‐changing nonlinearities

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract In this article, we investigate the existence and multiplicity of solutions to the Robin problem −Δu=λf(u)inΩ,∂u∂ν+γu=0on∂Ω,$$\begin{equation*} {\begin{cases} -\Delta u = \lambda f(u) & \text{in } \Omega,\\ \frac{\partial u}{\partial \nu } + \gamma u=0 & \text{on } \partial \Omega, \end{cases}} \end{equation*}$$where Ω⊂RN$\Omega \subset ...
