Recognizing Weighted Means in Geodesic Spaces

Foundations of Computational Mathematics
Geodesic metric spaces support a variety of averaging constructions for given finite sets. Computing such averages has generated extensive interest in diverse disciplines. Here we consider the inverse problem of recognizing computationally whether or not a given point is such an average, exactly or approximately. In nonpositively curved spaces, several

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Totally geodesic submanifolds of Teichmuller space

We show that any totally geodesic submanifold of Teichmuller space of dimension greater than one covers a totally geodesic subvariety, and only finitely many totally geodesic subvarieties of dimension greater than one exist in each moduli space.Comment ...

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Stroke and motor outcomes are associated with regional and age‐specific changes in periodic and aperiodic cortical activity

Experimental Physiology, EarlyView.
Abstract Historically, stroke and ageing have been associated with changes in narrow‐band periodic neuronal activity, but recent work has highlighted the importance of broad‐band aperiodic activity. Aperiodic activity is represented by the 1/f slope of power spectral density generated by cortical activity.

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, EarlyView.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Visual modulation of vestibular‐evoked balance response disturbed by posterior cortical atrophy

The Journal of Physiology, EarlyView.
Abstract figure legend Summary of key findings. (A) Effect of vision on balance responses to vestibular stimulation in controls. Mean galvanic vestibular stimulation (GVS)‐evoked response time‐course is shown without and with vision, illustrating how visual input ‘dampens’ the balance response.
