A Proposal of Portfolio Choice for Infinitely Divisible Distributions of Assets Returns [PDF]

open access: yes
In the paper we present a proposal of augmenting portfolio analysis for the infinitely divisible distributions of returns - so that the prices of assets can follow Lévy processes.

Distal femoral morphology as a risk factor for osteoarthritis

open access: yesThe Anatomical Record, EarlyView.
Abstract Osteoarthritis (OA) is a leading cause of disability affecting millions of adults in the United States, commonly resulting in the need for total knee arthroplasty (TKA) to restore mobility and quality of life. This study investigates potential differences in baseline distal femoral shape between individuals who received TKA due to OA and a ...

Effect of Time to Start of Biologic Therapy on Treatment Response in Childhood Arthritis: Results From the UCAN CAN‐DU Cohort

open access: yesArthritis &Rheumatology, EarlyView.
Objective To estimate the effect of time from symptom onset to start of biologic treatment on achieving inactive arthritis within six months in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The international UCAN CAN‐DU study prospectively enrolled patients with JIA across Canada and the Netherlands.

From Local Volatility to Local Levy Models. [PDF]

open access: yes
We define the class of local Lévy processes. These are Lévy processes time changed by an inhomogeneous local speed function. The local speed function is a deterministic function of time and the level of the process itself. We show how to reverse engineer

BSDEs and log-utility maximization for Lévy processes

open access: yesModern Stochastics: Theory and Applications, 2019
In this paper we establish the existence and the uniqueness of the solution of a special class of BSDEs for Lévy processes in the case of a Lipschitz generator of sublinear growth.

Legal and ethical considerations around the use of existing illustrations to generate new illustrations in the anatomical sciences

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 289-300, March 2025.
Abstract It is likely existing anatomical illustrations are often used as the basis for new illustrative works, given not all illustrators have access to human tissues, bodies, or prosections on which to base their illustrations. Potential issues arise with this practice in the realms of copyright infringement and plagiarism when authors are seeking to

Duality and Derivative Pricing with Lévy Processes [PDF]

open access: yes
The aim of this work is to use a duality approach to study the pricing of derivatives depending on two stocks driven by a bidimensional Lévy process. The main idea is to apply Girsanov's Theorem for Lévy processes, in order to reduce the posed problem to

Body donor programs in Australia and New Zealand: Current status and future opportunities

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.
Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.

Markov Regime Switching of Stochastic Volatility Lévy Model on Approximation Mode

open access: yesJournal of Applied Mathematics, 2013
This paper deals with financial modeling to describe the behavior of asset returns, through consideration of economic cycles together with the stylized empirical features of asset returns such as fat tails.

The lack of legal protections in the United States to prevent commercializing the dead for education and research: Consequences and risks to anatomists

open access: yesAnatomical Sciences Education, EarlyView.
Abstract A lack of minimum legal standards for body donation programs undermines recent strides by anatomy professionals to promote ethical best practices in the United States (US). In particular, the commercialization of the dead by nontransplant tissue banks poses a risk to the public trust in academic body donation programs.
