Masking Ability of CAD‐CAM Materials at Different Thicknesses: A Study on Color, Translucency, and Infinite Optical Thickness

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 37, Issue 9, Page 2134-2143, September 2025.
ABSTRACT Objective To evaluate the masking ability of different thicknesses of CAD‐CAM resin‐matrix and feldspar porcelain materials. Materials and Methods Specimens (Ø7.5 mm, thickness 0.5, 1.0, and 1.5 mm, n = 3/material) were fabricated from Lava Ultimate‐LU, Grandio Blocs‐GB, VITA Enamic‐VE, and VITA Mark II‐VM.

Brief Review of Soft Sets and Its Application in Coding Theory

open access: yesJournal of New Theory, 2020
In this paper, we will focus to one of the recent applications of PU-algebras in the coding theory, namely the construction of codes by soft sets PU-valued functions. First, we shall introduce the notion of soft sets PU-valued functions on PU-algebra and

Graded C*-algebras and twisted groupoid C*-algebras

open access: yes, 2019
Let $C^*$-algebra that is acted upon by a compact abelian group. We show that if the fixed-point algebra of the action contains a Cartan subalgebra $D$ satisfying an appropriate regularity condition, then $A$ is the reduced $C^*$-algebra of a groupoid twist.

Taking limits in topological recursion

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectral curve changes at the limit point. We provide sufficient (straightforward‐to‐use) conditions for checking when the commutation with limits holds, thereby closing a ...

Group C*-algebras as decreasing intersection of nuclear C*-algebras

open access: yes, 2016
We prove that for every exact discrete group $\Gamma$, there is an intermediate C*-algebra between the reduced group C*-algebra and the intersection of the group von Neumann algebra and the uniform Roe algebra which is realized as the intersection of a ...

Parity of ranks of Jacobians of curves

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 3, September 2025.
Abstract We investigate Selmer groups of Jacobians of curves that admit an action of a non‐trivial group of automorphisms, and give applications to the study of the parity of Selmer ranks. Under the Shafarevich–Tate conjecture, we give an expression for the parity of the Mordell–Weil rank of an arbitrary Jacobian in terms of purely local invariants ...

Semiprojectivity with and without a group action

open access: yes, 2014
The equivariant version of semiprojectivity was recently introduced by the first author. We study properties of this notion, in particular its relation to ordinary semiprojectivity of the crossed product and of the algebra itself.

MARTApp: software for the processing and reconstruction of synchrotron‐radiation‐based magnetic tomographies

open access: yesJournal of Synchrotron Radiation, Volume 32, Issue 4, Page 1095-1104, July 2025.
MARTApp is an open‐source software for magnetic vector reconstruction of the data acquired from magnetic transmission X‐ray microscopy. It automates the tasks of image normalization, alignment, computation of magnetic signal and the reconstruction of quasi‐2D and ‐3D systems.

Inductive limits of projective C*-algebras [PDF]

open access: yes, 2016
We show that a separable C*-algebra is an inductive limits of projective C*-algebras if and only if it has trivial shape, that is, if it is shape equivalent to the zero C*-algebra.
