One-parameter Lie groups and inverse integrating factors of n-th order autonomous systems

Journal of Mathematical Analysis and Applications, 2012
In the last years some works have appeared that show that the inverse integrating factors of a differential equations system can reveal some qualitative properties of the system. The key role that the inverse integrating factors play in the different theories of integrability has also been shown recently.

Generalized modes in Bayesian inverse problems [PDF]

, 2019
Uncertainty quantification requires efficient summarization of high- or even infinite-dimensional (i.e., non-parametric) distributions based on, e.g., suitable point estimates (modes) for posterior distributions arising from model-specific prior ...

A Geometry-Driven Quantitative Modeling Framework for Image-Based Human Motion Evaluation: Application to Sub-Pixel Posture Analysis and Feature Attribution

Mathematics
Quantitative evaluation of human motion from image data requires both high geometric precision and mathematical interpretability. To address the limitations of pixel-level posture analysis and empirical performance scoring, this study proposes a geometry-

Bioengineered 3D Human Trabecular Meshwork Models for Outflow Physiology and Glaucoma Research

Bioengineering
Primary open angle glaucoma (POAG) is one of the leading causes of irreversible blindness and is associated with dysfunction of the trabecular meshwork (TM), a three-dimensional (3D) structure that regulates aqueous humor outflow and, consequently ...

THE INVERSE LEWBEL DEMAND SYSTEM [PDF]

A new model of consumer preferences is introduced. It is appropriate for modeling perishable commodities which are produced with a lag, where it is reasonable to assume the market-level quantities are fixed by previously made production decisions.
