Do State Lotteries Exploit their Lottery Power? Optimal Lotto Pricing With Heterogeneous Players: Evidence from the United Kingdom

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We propose a new model of revenue‐maximising lottery pricing under income‐related heterogeneity and apply it to 13 years of UK National Lottery data. Our pricing rule shows how a state's lottery power is shaped by heterogeneities in lotto demand and the income distribution, and we study its efficiency and distributional implications.

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

Cosmological models with Lagrange multiplier field [PDF]

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2011
We first consider the Einstein-aether theory with a gravitational coupling and a Lagrange multiplier field, and then consider the non-minimally coupled quintessence field theory with Lagrange multiplier field.
