A unified field theory from a complexified quaternion-octonion Dirac equation [PDF]

open access: yesarXiv, 2022
It is set manifest an underlying algebraic structure of Dirac equation and solutions, in terms of Cl2 Clifford algebra projectors and ladder operators. From it, a scheme is proposed for constructing unified field theories by enlarging the pointed algebra.

Beyond Intent: Technology Adoption and Appropriation by University Staff [PDF]

open access: yes, 2010
In this paper, we propose a model for understanding adoption and appropriation of technology. We describe a university-wide system that is designed for faculty and students, but which has been adopted by staff, followed by a survey study and some ...

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

open access: yesAdvanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
