Longitudinal analysis of hippocampal subfield atrophy and network centrality associated with cognitive decline in Alzheimer's disease progression

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by structural degeneration of the hippocampus. Previous studies have demonstrated that specific hippocampal subfields, such as the cornu ammonis (CA)1 and the subiculum, are susceptible to AD‐related atrophy.

Geodesics and Almost Geodesics Curves

Results in Mathematics, 2018
An \textit{almost geodesic} of an affine connection \(\nabla\) on a manifold is a curve \(x(t)\) in the manifold so that \[ \nabla^2_{\dot{x}}\dot{x}=a\nabla_{\dot{x}} \dot{x}+b\dot{x}, \] for some real-valued continuous functions \(a(t)\), \(b(t)\).

Geodesic compatibility and integrability of geodesic flows

Journal of Mathematical Physics, 2003
We give a natural geometric condition called geodesic compatibility that implies the existence of integrals in involution of the geodesic flow of a pseudo-Riemannian metric. We prove that if two metrics satisfy the condition of geodesic compatibility then we can produce a hierarchy of metrics that also satisfy this condition. A lot of metrics studed in
