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.

The topology of partial metric spaces [PDF]

open access: yes
The T0 world of Scott's topological models used in the denotational semantics of programming languages may at first sight appear to have nothing whatever in common with the Hausdorff world of metric space theory.

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.

Besov spaces and Hausdorff dimension for some CarnotCaratheodory metric spaces

open access: yes, 2014
. We regard a system of left invariant vector fields X = {X1,..., Xk} satisfying the Hörmander condition and the related Carnot-Carathéodory metric on a unimodular Lie group G.

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 ...

Gromov-Hausdorff compactness theorem for non-Archimedean fuzzy metric spaces

open access: yes
The authors introduced in a previous paper the notion of fuzzy Gromov-Hausdorff distance between non-Archimedean compact fuzzy metric spaces, presenting a fuzzy version of the Gromov's completeness theorem. In this paper we present a fuzzy version of the

Development and Validation of an AI‐Integrated System for Automated Fracture Detection and Pedicle Puncture Planning in Lumbar Osteoporotic Vertebral Compression Fractures Based on the Nine‐Grid Area Division Method

open access: yesOrthopaedic Surgery, Volume 18, Issue 6, Page 1266-1277, June 2026.
This study developed a three‐module AI‐integrated software. Its effectiveness was verified, and it was confirmed to have certain transformation potential. ABSTRACT Objective The clinical application of the Nine‐grid Area Division Method for pedicle puncture in L‐OVCF is limited by high technical thresholds and low efficiency.

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.
