Guiding and Manipulating Light Fields in Microstructured Liquid Crystals
Advanced Physics Research, EarlyView.This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Face and Construct Validity of a Grapefruit Arthroscopy Training Model With Active Fluid Management
Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.Purpose To evaluate the face and construct validity of a grapefruit arthroscopy training model with active fluid management across varying levels of arthroscopic experience. Methods Orthopaedic residents, fellows, and attending surgeons were stratified into novice (n = 10), intermediate (n = 10), and advanced (n = 9) groups.

Anatomical 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

Lévy copulae for financial returns
Dependence Modeling, 2016 The paper uses Lévy processes and bivariate Lévy copulae in order to model the behavior of intraday log-returns. Based on assumptions about the form of marginal tail integrals and a Clayton Lévy copula, the model allows for capturing intraday cross ...

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

On the reducibility of affine models with dependent Lévy factors
Modern Stochastics: Theory and ApplicationsThe paper is devoted to the study of the short rate equation of the form \[ \text{d}R(t)=F(R(t))\text{d}t+{\sum \limits_{i=1}^{d}}{G_{i}}(R(t-))\text{d}{Z_{i}}(t),\hspace{1em}R(0)={R_{0}}\ge 0,\hspace{3.33333pt}t\gt 0,\] with deterministic functions
