A digital workflow for full‐arch implant fixed prosthesis: Clinical application of a 3D‐printed polychromatic flangeless trial denture, anatomic bone reduction guide, and intraoral scanning for definitive prosthesis fabrication

open access: yesJournal of Prosthodontics, EarlyView.
Abstract This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full‐arch, implant‐supported fixed dental prosthesis (FP‐1). It highlights the integration of a 3D‐printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling ...

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

Clifford quantum computer and the Mathieu groups

open access: yes, 2009
One learned from Gottesman-Knill theorem that the Clifford model of quantum computing \cite{Clark07} may be generated from a few quantum gates, the Hadamard, Phase and Controlled-Z gates, and efficiently simulated on a classical computer.

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Generalized Quadrangles and Flocks of Cones

open access: yesEuropean Journal of Combinatorics, 1987
A flock of the quadratic cone K of PG(3,q) is a partition of K but its vertex into disjoint conics. It is called linear if the planes of the q conics of such a flock all contain a common line. A flock is linear if and only if there corresponds a Desarguesian translation plane to it. W. M.

Exploring 2D Geometric Shape Classification Using AI‐Driven Feature Tables in Mathematics

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study explored the effectiveness of an AI‐integrated instructional task designed to enhance preservice teachers' understanding of the features and hierarchical relationships of 2D geometric shapes. Originally developed and tested in online K‐12 professional development settings, this intervention was adapted for in‐person preservice ...

Geometrical Constructions of Flock Generalized Quadrangles

open access: yesJournal of Combinatorial Theory, Series A, 2001
Let \({\mathbf K}\) be a quadratic cone of PG\((3,q)\) with vertex a point \(v\). A partition of \({\mathbf K}\setminus \{v\}\) into \(q\) irreducible conics is a flock of \({\mathbf K}.\) It was shown by J. A. Thas in 1987 that with a flock \({\mathcal F}\) there corresponds a set, called a \(q\)-clan, of \(q\) upper triangular matrices of order \(2\)

An Efficient Geometrically‐Exact Nonlinear Shell Formulation Based on Rodrigues Parameters

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Thin‐walled structures are part of many engineering applications, as wind turbine blades, pressure vessels, and sheet metal products. A thin‐walled structure is characterized by one significantly smaller dimension compared to the others.

US‐Japan Alliance: Emmeshing Bilateralism Into Broader Multilateralism

open access: yesAsia &the Pacific Policy Studies, Volume 13, Issue 2, May 2026.
ABSTRACT In the 21st Century, geopolitical confrontation between the Eurasian continental powers and the sea powers works to divide Asia. The US‐Japan alliance has transformed itself from Japanʼs asymmetrical security dependence of the Cold War period into a mutual and more integrated partnership today.
