Measuring Lead Userness: Development and Validation of a Hierarchical Scale

open access: yesCreativity and Innovation Management, Volume 34, Issue 4, Page 944-962, December 2025.
ABSTRACT Lead user theory has gained traction in both academia and practice, given that involving lead users (LUs) can yield more innovative and commercially successful products. Yet, measurement inconsistencies have hindered consensus on how to reliably assess lead userness.

Holography and Emergence [PDF]

open access: yes, 2013
In this paper, I discuss one form of the idea that spacetime and gravity might ‘emerge’ from quantum theory, i.e. via a holographic duality, and in particular via AdS/CFT duality.

Violation of the holographic principle in the loop quantum gravity [PDF]

open access: yes, 2016
In this paper, we analyze the holographic principle using loop quantum gravity (LQG). This will be done by using polymeric quantization for analysing Yurtsever's holographic bound on the entropy, which is obtained from local quantum field theories.

An inelastic bound on chaos

open access: yesJournal of High Energy Physics, 2019
We study a generalization of the chaos bound that applies to out-of-time-ordered correlators between four different operators. We prove this bound under the same assumptions that apply for the usual chaos bound and extend it to non-hermitian operators ...

Graphene oxide–modified fluoridated varnish promotes mineral recovery in demineralized bovine enamel: An in vitro study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the efficacy of an experimental fluoridated varnish modified with graphene oxide (GO) nanoparticles in arresting initial caries lesion progression and promoting mineral recovery in demineralized bovine enamel.

Thickness variation of self-processing acrylamide-based photopolymer and reflection holography [PDF]

open access: yes, 2000
There are many types of holographic recording material. The acrylamide-based recording material examined here has one significant advantage: it is self-processing.

Extended Reality in Endodontics: A Review of Current Applications and Future Potential

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.

Hyperspectral tomographic diffractive microscopy: Development and applications

open access: yesJournal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

Enhancing the Eyebox Brightness and Size in Augmented Reality Waveguide Devices via Polarization Multiplexing

open access: yesAdvanced Photonics Research, Volume 7, Issue 10, October 2026.
Proposed 4‐zone system with 2D exit pupil expansion with 4 separate and selectable paths. An initial PBD in combination with two switchable polarizers enables the selection between the IC set of path (a) and path (b) or between the other IC set of path (c) and path (d). Waveguide‐based augmented reality displays often suffer from low optical efficiency.
