Parallel Vectors Extraction using Bézier Clipping
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

This article investigates a new Appell-type sequence, the telephone polynomials, which extend the classical telephone (involution) numbers. We present their fundamental algebraic properties, structural characterizations, and diverse interconnections with

Hermite polynomials and Fibonacci oscillators [PDF]
We compute the (q1, q2)-deformed Hermite polynomials by replacing the quantum harmonic oscillator problem to Fibonacci oscillators. We do this by applying the (q1, q2)-extension of Jackson derivative. The deformed energy spectrum is also found in terms of these parameters. We conclude that the deformation is more effective in higher excited states.

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

ABSTRACT Background Adults with intellectual disability experience significant health issues that increase with age. Longitudinal analyses offer important evidence on how the trajectories of these conditions' develop and change. Methods Data were drawn from five waves of IDS‐TILDA, with a nationally representative sample of over 700 adults with ...

Longevity, Health, and Housing Risk Management in Retirement
ABSTRACT Annuities, long‐term care insurance, and reverse mortgages remain puzzlingly unpopular to manage post‐retirement longevity, health, and housing price risks. We use a flexible life‐cycle model structurally estimated with a unique stated‐preference survey experiment of Canadian households to understand why. Key factors include high risk aversion,
