Characterizing Round Spheres Using Half-Geodesics [PDF]
, 2019 A half-geodesic is a closed geodesic realizing the distance between any pair of its points. All geodesics in a round sphere are half-geodesics. Conversely, this note establishes that Riemannian spheres with all geodesics closed and sufficiently many half-

Accelerated Brain Atrophy in Epilepsy: A Prospective Population‐Based Study
Annals of Neurology, EarlyView.Objective Previous longitudinal neuroimaging studies suggest that epilepsy is a progressive disorder. To date, these findings have relied largely on populations from tertiary centers, resulting in ascertainment bias, as severely affected individuals are more likely to be rescanned.

Geodesic flows in cosmology [PDF]
Journal of Physics: Conference Series, 2008 In this brief note we discuss geodesic flows that correspond to cosmological solutions in higher-dimensional supergravity. On the one hand, we explain that S-brane solutions are in one-to-one correspondence with geodesic curves on the moduli space through dimensional reduction over the brane worldvolume.

Archaeological Prospection, EarlyView.ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Autism Research, EarlyView.ABSTRACT The heterogeneity in both the neurobiological mechanisms and the phenotypic presentations of autism spectrum disorder (ASD) poses a major challenge to clinical and translational research. Alterations in functional connectivity (FC) have been associated with ASD, yet it remains unclear whether and how divergent brain network properties may ...

Geodesics Using Mathematica [PDF]
, 2017 We describe surfaces and geodesics without assuming prior knowledge of differential geometry. This involves selecting and presenting basic definitions and theorems.

Autism Research, EarlyView.ABSTRACT Autistic individuals frequently report heightened sensitivity to visual stimuli, often described as discomfort in environments with bright or flickering lights. These experiences are hypothesized to reflect underlying differences in sensory gain or neural hyperexcitability; however, findings across studies have yielded mixed results, likely ...

TRIANGLES, SQUARES AND GEODESICS
International Journal of Algebra and Computation, 2012 In the early 1990s Steve Gersten and Hamish Short proved that compact nonpositively curved triangle complexes have biautomatic fundamental groups and that compact nonpositively curved square complexes have biautomatic fundamental groups. In this paper we report on the extent to which results such as these extend to nonpositively curved complexes built
