Topological turning points across the human lifespan [PDF]

open access: yesNature Communications
Structural topology develops non-linearly across the lifespan and is strongly related to cognitive trajectories. We gathered diffusion imaging from datasets with a collective age range of zero to 90 years old (N = 4,216).

Managing Contextual Complexity in an Experiential Learning Course: A Dynamic Systems Approach through the Identification of Turning Points in Students' Emotional Trajectories [PDF]

open access: yesFrontiers in Psychology, 2017
This study adopts a dynamic systems approach to investigate how individuals successfully manage contextual complexity. To that end, we tracked individuals' emotional trajectories during a challenging training course, seeking qualitative changes–turning ...

Cosmologies with turning points

open access: yesPhysics Letters B, 2023
We explore singularity-free and geodesically-complete cosmologies based on manifolds that are not quite Lorentzian. The metric can be either smooth everywhere or non-degenerate everywhere, but not both, depending on the coordinate system.

Period function of planar turning points

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
This paper is devoted to the study of the period function of planar generic and non-generic turning points. In the generic case (resp. non-generic) a non-degenerate (resp.

Forensic Turning Points: Exhumations, Dignity, and Iconoclasm

open access: yesLingue Culture Mediazioni, 2022
Between 100,000 and 130,000 people were murdered during the war and dictatorship in Spain from 1936 onward. Thousands of bodies were buried in mass graves which were then monumentalized decades later.

The Uniqueness Theorem for the Solutions of Dual Equations of Sturm-Liouville Problems with Singular Points and Turning Points [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
In this paper, linear second-order differential equations of Sturm-Liouville type having a finite number of singularities and turning points in a finite interval are investigated.
