Investigation and evaluation of the morphology properties of carbon nanowalls based on fractal analysis and Minkowski functionals

open access: yesPhysical Sciences and Technology, 2022
It is well-known that at the nano-scale, morphology can play a crucial role in the properties of nanomaterials and there is still a challenging task to control it during the synthesis.

Induced vacuum currents in anti-de Sitter space with toral dimensions

open access: yesPhysics Letters B, 2015
We investigate the Hadamard function and the vacuum expectation value of the current density for a charged massive scalar field on a slice of anti-de Sitter (AdS) space described in Poincaré coordinates with toroidally compact dimensions.

On the Existential Theory of the Completions of a Global Field

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We discuss the common existential theory of all or almost all completions of a global function field.

On Geometric Phase Model in the Theory of Curves With Myller Configuration

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we introduce a linearly polarized light wave in an optical fiber and rotation of the polarization plane through the Frenet‐type frame with Myller configuration. Since the geometric evaluation and interpretations of a polarized light wave are associated with geometric phase, a new type of geometric phase model has been ...

Celestial holography revisited. Part II. Correlators and Källén-Lehmann

open access: yesJournal of High Energy Physics
In this work we continue the investigation of the extrapolate dictionary for celestial holography recently proposed in [1], at both the perturbative and non-perturbative level.

On the derivative of the $\alpha$-Farey-Minkowski function

open access: yesDiscrete and Continuous Dynamical Systems, 2014
In this paper we study the family of $\alpha$-Farey-Minkowski functions $\theta_\alpha$, for an arbitrary countable partition $\alpha$ of the unit interval with atoms which accumulate only at the origin, which are the conjugating homeomorphisms between each of the $\alpha$-Farey systems and the tent map. We first show that each function $\theta_\alpha$

Refinements of some classical inequalities via superquadraticity

open access: yesJournal of Inequalities and Applications, 2022
Some new refined versions of the Jensen, Minkowski, and Hardy inequalities are stated and proved. In particular, these results both generalize and unify several results of this type. Some results are also new for the classical situation.

Abelian number fields with frobenian conditions

open access: yesMathematika, Volume 72, Issue 4, October 2026.
Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

Remarks on the Maximal Regularity for Parabolic Boundary Value Problems With Inhomogeneous Data

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 15316-15326, 15 September 2026.
ABSTRACT Inspired by Ogawa‐Shimizu and Chen‐Liang‐Tsai on the second and first order derivative estimates of solutions of the heat equation in the upper half space with boundary data in homogeneous Besov spaces, we extend the estimates to any order of derivatives, including fractional derivatives.

Single Linkage Weighted Steepest Gradient Adaboost Cluster-Based D2D in 5G Networks

open access: yesJournal of Telecommunications and Information Technology, 2023
Efficiency of data transmissions with minimum latency levels and better resource utilization is a challenging issue in 5 G device-to-device (D 2D) environments.
