Guiding the AI revolution in periodontology and implant dentistry: Concepts, ethics, accountability, and a roadmap for sustainable adoption

Periodontology 2000, EarlyView.
Abstract Background Artificial intelligence (AI) is increasingly gaining attention in the field of periodontology and implant dentistry. Currently developed models can support diagnosis, treatment planning, and maintenance monitoring. However, most of the available literature is based on retrospective and often single‐modality data sets.

An unconditionally stable nonstandard finite difference method applied to a mathematical model of HIV infection [PDF]

International Journal of Applied Mathematics and Computer Science, 2013
We formulate and analyze an unconditionally stable nonstandard finite difference method for a mathematical model of HIV transmission dynamics. The dynamics of this model are studied using the qualitative theory of dynamical systems. These qualitative features of the continuous model are preserved by the numerical method that we propose in this paper ...

There Is More Than Meets the Eye: The Dual Role of Perception in Shaping Color Lexicons

Topics in Cognitive Science, EarlyView.
Abstract Color's ultimate physical reality is continuous, and yet human beings “cut” this continuum into a rather small number of categories reflected in their languages’ color lexicon. There are striking cross‐linguistic differences in the color lexicon, which are primarily attributed to differences in communicative needs, but also striking ...

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

Interdisciplinary Materials, Volume 5, Issue 5, Page 834-867, September 2026.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

SelExNet: A Self‐Supervised Physics‐Informed Framework for Multi‐Channel Joint RF and Gradient Waveform Optimization in 2D Spatially Selective Excitation

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1219-1234, September 2026.
ABSTRACT Purpose To introduce SelExNet: a self‐supervised framework for two‐dimensional spatially selective excitation that jointly optimizes radiofrequency (RF) pulses and gradient waveforms, and extends to multi‐channel transmission MRI. Methods Building on prior RF‐only and joint RF‐gradient optimization approaches, SelExNet couples neural RF and ...

Accurate and Efficient Data‐Driven Partitioned Scheme for Coupled Heterogeneous Numerical Models

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT Heterogeneous numerical models (HNMs) combine conventional discretization modules such as finite elements with nonconventional data‐driven and reduced‐order modules. HNMs can improve computational efficiency and enable simulations of multi‐physics systems in which one or more constituent components lack first‐principles descriptions and must ...

Automatic Workout Mortgage and Housing Consumption Choice

International Review of Finance, Volume 26, Issue 3, September 2026.
ABSTRACT This paper further develops the Automatic Workout Mortgage (AWM) which embeds an insurance put option to reduce negative equity, systemic risk and promote economic recovery. We introduce a mathematical model showing that AWM raises household utility and increases housing demand.
