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)

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 ...

Axially Symmetric Null Dust Space-Time, Naked Singularity, and Cosmic Time Machine

Advances in High Energy Physics, 2017
We present a gravitational collapse null dust solution of the Einstein field equations. The space-time is regular everywhere except on the symmetry axis where it possesses a naked curvature singularity and admits one parameter isometry group, a generator

On The Closed Geodesics Problem

The São Paulo Journal of Mathematical Sciences, 2008
In this paper we review some important results on the closed geodesics problem for compact Riemannian manifolds, as the Gromoll-Mayer Theorem, and discuss some extension of those results to the case of Finsler and semi Rimannian manifolds.

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

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 ...

Closed geodesics on surfaces

, 2021
Diese Arbeit beschäftigt sich mit Geodätischen auf Flächen. Im ersten Teil der Arbeit werden Ergebnisse von Thorbergsson und Bangert über die Existenz geschlossener Geodätischen auf Flächen mit vollständigen riemannschen Metriken auf reversible und zum Teil auch auf allgemeine Finsler-Metriken ausgeweitet.

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

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 ...

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

Business 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 ...

Lengths of closed geodesics for certain warped product metrics and nearly round metrics on spheres

Journal of Inequalities and Applications
We study warped product metrics on spheres and prove that the shortest length of closed geodesics for such metrics can be bounded above by its volume, under suitable assumptions on the warping function.

Climate Change, Strategic Orientation, and Green Innovation: Unpacking External and Internal Drivers in Competitive Contexts

Business Strategy and the Environment, EarlyView.
ABSTRACT Firms increasingly face political and societal pressures to pursue green strategies and sustainable innovation amid escalating climate change disruptions. Drawing upon contingency theory, institutional theory, and the natural resource‐based view, this article examines external (stakeholder pressures) and internal (environmental culture ...

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates

Chemistry – A European Journal, EarlyView.
Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium
