Causal Inference With Observational Data and Unobserved Confounding Variables. [PDF]

Ecol Lett
As ecology tackles progressively larger problems, we are moving beyond the scales at which randomised controlled experiments are feasible. Using observational data for causal inference raises the problem of confounding variables, those affecting both a causal variable and response of interest, which can create bias when not measured and omitted from ...

Patient Safety/Quality Improvement Primer, Part IV: How to Measure and Track Improvements

Otolaryngology–Head and Neck Surgery, Volume 169, Issue 6, Page 1683-1690, December 2023., 2023
Abstract Patient safety and quality improvement (PS/QI) has become an integral part of the health care system, and the ability to effectively use data to track, understand, and communicate performance is essential to designing and implementing quality initiatives, as well as assessing their impact.

Postoperative full leg radiographs exhibit less residual coronal varus deformity compared to intraoperative measurements in robotic arm‐assisted total knee arthroplasty with the MAKO™ system

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 31, Issue 9, Page 3912-3918, September 2023., 2023
Abstract PurposeRobotic arm‐assisted total knee arthroplasty (raTKA), currently a major trend in knee arthroplasty, aims to improve the accuracy of implant positioning and limb alignment. However, it is unclear whether and to what extent manual radiographic and navigation measurements with the MAKO™ system correlate. Nonetheless, a high agreement would

Hamiltonian chaos and differential geometry of configuration space–time

, 2021
This paper tackles Hamiltonian chaos by means of elementary tools of Riemannian geometry. More precisely, a Hamiltonian flow is identified with a geodesic flow on configuration space–time endowed with a suitable metric due to Eisenhart.

Gravitational Waves and Conformal Time Transformations

, 2022
International audienceRecent interest in the "memory effect" prompted us to revisit the relation of gravitational waves to oscillators. 50 years ago Niederer [1] found that an isotropic harmonic oscillator with a constant frequency can be mapped onto a ...

Joint‐specific measures improve risk adjustment in total knee arthroplasty: A machine learning approach

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Accurate risk adjustment in total knee arthroplasty (TKA) is essential for outcome prediction and quality assessment. Most existing prediction models rely solely on patient demographics and comorbidities and do not account for joint‐specific pathology.

From Rating System to Thought Leadership: The Evolution of the Canada Green Building Council

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT Green Building Social Movement Organizations encourage the adoption of green buildings, primarily by promoting sustainability rating tools. While numerous papers have explored the market impact of these sustainability rating tools, very few have examined either the lengthy and protracted process of their selection and enrollment by ...

Time-Dependent Conformal Transformations and the Propagator for Quadratic Systems

, 2021
International audienceThe method proposed by Inomata and his collaborators allows us to transform a damped Caldirola–Kanai oscillator with a time-dependent frequency to one with a constant frequency and no friction by redefining the time variable ...
