Weak mixing suspension flows over shifts of finite type are universal [PDF]
Let S be an ergodic measure-preserving automorphism on a non-atomic probability space, and let T be the time-one map of a topologically weak mixing suspension flow over an irreducible subshift of finite type under a Holder ceiling function.

Cross sections for geodesic flows and \alpha-continued fractions
We adjust Arnoux's coding, in terms of regular continued fractions, of the geodesic flow on the modular surface to give a cross section on which the return map is a double cover of the natural extension for the \alpha-continued fractions, for each ...

Worklow for calibrating excursion sets of random fields using methods from generative artificial intelligence. This article presents a computational method for generating virtual 3D morphologies of functional materials using low‐parametric stochastic geometry models, that is, digital twins, calibrated with 2D microscopy images.

Underwater Image Restoration Using Geodesic Color Distance and Complete Image Formation Model
Underwater images suffer from different types of quality degradation, including haze, blur, low contrast, and color distortion, owing to light scattering and absorption.

Geodesic mappings of pseudo-Riemannian manifolds
The author considers the metrics \(g\) and \(\overline{g}\) on a pseudo- Riemannian manifold \(M\) which are in geodesic correspondence. He describes the local structure of such manifolds with an arbitrary Segre characteristic of the form \(\overline{g}\). This structure theorem generalizes the result of \textit{A. Aminova} [Tensor, New Ser.

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity
This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)
ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...

Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)
ABSTRACT A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved.

Instantons from geodesics in AdS moduli spaces
We investigate supergravity instantons in Euclidean AdS5 × S5/ℤk. These solutions are expected to be dual to instantons of N $$ \mathcal{N} $$ = 2 quiver gauge theories.
