Almost complex surfaces in the nearly Kaehler S6

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
It is shown that a compact almost complex surface in S6 is either totally geodesic or the minimum of its Gaussian curvature is less than or equal to 1/3.

Accelerated Brain Atrophy in Epilepsy: A Prospective Population‐Based Study

open access: yesAnnals 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.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

open access: yesArchaeological 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 ...

Cortical Network Overconnectivity Relates to Sensory, Cognitive, and Social Dimensions in Young Children With Autism Spectrum Disorder

open access: yesAutism 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 ...

On balls and totally geodesic submanifolds [PDF]

open access: yesAnnales Polonici Mathematici, 1984
Let (M,g) be a Riemannian manifold and let N be a submanifold of (M,g). Further, let \(x\in N\) and denote by \(B_ N(x,r)\) (or \(B_ M(x,r)\), respectively) the open geodesic ball on N (or M, respectively) with center x and radius r. N is said to be \(\epsilon\)-regular if \(B_ N(x,r)=B_ M(x,r)\cap N\) for any \(x\in N\) and \(r\in (0,\epsilon).\) In ...

Visual Responsivity in Autism: Measuring Visual Responses in Autistic and Non‐Autistic Adults Using Psychophysics, fMRI, and EEG

open access: yesAutism 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 ...

Compact Totally Real Minimal Submanifolds in a Bochner-Kaehler Manifold

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper, we establish the following results: Let $M$ be an $% m-$dimensional compact totally real minimal submanifold immersed in a locally symmetric Bochner-Kaehler manifold $\tilde{M}$ with Ricci curvature bounded from below. Then either $M$ is a

From Centrality to Sustainability: How Connected Boards Shape Waste Management Outcomes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The escalating climate crisis has elevated waste management from an operational concern to a critical issue of corporate governance. However, the role of board connectedness in shaping firms' waste practices remains largely unexplored. Drawing on resource dependency and social capital theories, this study examines how board network centrality ...

Totally real submanifolds of generalized Hopf manifolds

open access: yesLe Matematiche, 1987
We classify totally geodesic totally-real submanifolds of generalized Hopf manifolds, provided the normal connection is flat.
