Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering

Mathematical Finance, EarlyView.
ABSTRACT Whereas data on implied volatilities are available for a large number of assets, this is less frequently the case of implied covolatilities. We introduce a new approach based on static and dynamic Wishart models to solve this problem of missing data.

On the photon–classical electromagnetic field relationship

Annals of the New York Academy of Sciences, EarlyView.
Abstract This paper discusses how the two ways in which the wavefunction of a free‐propagating photon can be introduced—starting from the relativistic energy−momentum relationship or based on the electromagnetic field, in particular on Riemann–Silberstein vectors—are not entirely equivalent since they can lead to different consequences regarding photon

A Neural Network Model for Intelligent Classification of Distal Radius Fractures Using Statistical Shape Model Extraction Features

Orthopaedic Surgery, Volume 17, Issue 5, Page 1513-1524, May 2025.
This study developed an automated distal radius fracture classification system based on statistical shape model (SSM) feature extraction and neural network classification. The method first extracts point cloud data from CT images, then extracts fracture features through registration, downsampling, and PCA dimensionality reduction, before inputting them

A Computer Vision‐Based Methodology to Estimate Fruit Colour Diversity in Ornamental Pepper (Capsicum spp.)

Plant Breeding, EarlyView.
ABSTRACT Fruit colour diversity within different ripening stages confers ornamental value for pepper plants. Using images can be helpful in analysing the fruit colour‐related genetic diversity and enable selecting accessions for ornamental purposes by avoiding subjectiveness.
