A Short Note on Fractal Interpolation in the Space of Convex Lipschitz Functions

Fractal and Fractional
In this short note, we consider fractal interpolation in the Banach space Vθ(I) of convex Lipschitz functions defined on a compact interval I⊂R. To this end, we define an appropriate iterated function system and exhibit the associated Read–Bajraktarević ...

EffiSegNet: Advances in Automated Segmentation of Actinic Cheilitis and Lip Squamous Cell Carcinoma in Clinical Photographs

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Actinic cheilitis (AC) is a potentially malignant oral disorder linked to lip squamous cell carcinoma (LSCC). Clinical diagnosis is hindered by lesion heterogeneity. While AI tools have shown promise in oral lesion detection and diagnosis, image segmentation remains underexplored. This study developed and externally validated a deep

Beyond the Moderating Role of Neuroticism on Evaluative Conditioning: Threat Appraisal

Journal of Personality, EarlyView.
ABSTRACT Objective Reality perception is often altered by general dispositional factors that are associated with emotional vulnerability and emerge in a specific learning context. The current study examined whether neuroticism and looming cognitive style, factors that account for emotional vulnerability, interact to influence emotional learning ...

Understanding Online Meaning‐Making: Normativity, Polycentricity, and Memetic Communication Through a Chronotopic‐Scalar Lens

Journal of Sociolinguistics, EarlyView.
ABSTRACT This article investigates memetic interaction as an illustrative example of complex polycentric online communication. Using a chronotopic‐scalar framework, it offers a theorized account of how online (inter)action works, how it is guided by (perceptions of) normativities, and how it is in dialogue with the “offline.” Specifically, I focus on ...

Fractal Analysis of Periodontal Tissues in Geriatric Patients With Different Periodontal Conditions: A Retrospective Study

Oral Diseases, EarlyView.
ABSTRACT Objective This study evaluated the relationship between fractal dimension (FD) values and periodontal status in geriatric patients using digital panoramic radiographs. Methodology In this retrospective observational study, 147 elderly individuals were classified as periodontally healthy (n = 30), gingivitis (n = 32), Stage I periodontitis (n =

Research on a dynamic early warning model for gas outbursts using adaptive fractal dimension characterization

International Journal of Mining Science and Technology
To address the issues of single warning indicators, fixed thresholds, and insufficient adaptability in coal and gas outburst early warning models, this study proposes a dynamic early warning model for gas outbursts based on adaptive fractal dimension ...

Contractive Multivariate Zipper Fractal Interpolation Functions

Results in Mathematics
AbstractIn this paper we introduce a new general multivariate fractal interpolation scheme using elements of the zipper methodology. Under the assumption that the corresponding Read-Bajraktarevic operator is well-defined, we enlarge the previous frameworks occurring in the literature, considering the constitutive functions of the iterated function ...

Is the World Getting Smaller? Network‐Driven Heterogeneity in Gravity‐Model Elasticities

The World Economy, EarlyView.
ABSTRACT Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks.

A Coarse Geometric Approach to Graph Layout Problems

Journal of Graph Theory, Volume 113, Issue 2, Page 169-194, October 2026.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

One‐Class Autoencoders for Porcelain Art Attribution: The Case of William Billingsley

Archaeometry, Volume 68, Issue 5, Page 1110-1122, October 2026.
ABSTRACT This comprehensive study explores the application of advanced machine learning techniques, specifically one‐class autoencoders, for the authentication and attribution of English porcelain artworks. Focusing primarily on the works of William Billingsley (1758–1828), one of England's most celebrated porcelain decorators, we demonstrate how ...
