Structure and pressure-induced ferroelectric phase transition in antiphase domain boundaries of strontium titanate from first principles

Nava Setter, Alexander Tagantsev, Alexander Kvasov

In this work, using zero kelvin ab initio calculations, we revisit the structure and ferroelectric phase transition in antiphase domain boundaries (APBs) in SrTiO3 (STO), which has been previously addressed in terms of a phenomenological approach. We confi ...

Stability of stationary wave maps from a curved background to a sphere

Sohrab Mirshams Shahshahani

We study time and space equivariant wave maps from

M \times \mathbb{R} \rightarrow S^2

, where

M

is dieomorphic to a two dimensional sphere and admits an action of

SO(2)

by isometries. We assume that metric on

M

can be written as $dr^2+f^2(r)d\theta ...

Wireless Channel Characterization in Burning Buildings Over 100-1000 MHz

Andrew Charles Mallory Austin

A 3-D implementation of the finite-difference time-domain (FDTD) method is used to model 100-1000-MHz radio wave propagation in a generalized office building. Fire within this building is modeled as a cold plasma medium. The presence of fire is found to de ...

Multisensory effects on somatosensation: a trimodal visuo-vestibular-tactile interaction

Olaf Blanke, Bruno Herbelin, Mariia Kaliuzhna

Vestibular information about self-motion is combined with other sensory signals. Previous research described both visuo-vestibular and vestibular-tactile bilateral interactions, but the simultaneous interaction between all three sensory modalities has not ...

Characterization of rotational behavior of web-flange junctions of pultruded GFRP bridge decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The rotational behavior of the web-flange junctions (WFJs) of a pultruded GFRP bridge deck system was investigated. The rotational response of three WFJ types was characterized. An experimental procedure based on three-point bending and cantilever experime ...

The vestibular implant: frequency-dependency of the electrically evoked vestibulo-ocular reflex in humans

Thuy Anh Khoa Nguyen, Maurizio Ranieri

The vestibulo-ocular reflex (VOR) shows frequency-dependent behavior. This study investigated whether the characteristics of the electrically evoked VOR (eVOR) elicited by a vestibular implant, showed the same frequency-dependency. Twelve vestibular electr ...

Inference of perceptual priors from path dynamics of passive self-motion

Olaf Blanke, Danilo Jimenez Rezende

The monitoring of one's own spatial orientation depends on the ability to estimate successive self-motion cues accurately. This process has become to be known as path integration. A feature of sequential cue estimation, in general, is that the history of p ...

The Geometry of Eye Movement Dynamics

Simon Nessim Henein, Ilan Vardi

Eye movements consist of spherical rotations, with orientation generally constrained by Listing’s law. Our main result is a complete explicit formulation of ballistic eye movement under the Listing constraint. We present a conceptual framework for eye move ...

Accuracy and Precision of Head Motion Information in Multi-Channel Free Induction Decay Navigators for Magnetic Resonance Imaging

Tobias Kober, Michael Herbst

Free induction decay (FID) navigators were found to qualitatively detect rigid-body head movements, yet it is unknown to what extent they can provide quantitative motion estimates. Here, we acquired FID navigators at different sampling rates and simultaneo ...

Learning to integrate contradictory multisensory self-motion cue pairings

Olaf Blanke, Mariia Kaliuzhna, Steven Gale, Sunho Lee

Humans integrate multisensory information to reduce perceptual uncertainty when perceiving the world and self. Integration fails, however, if a common causality is not attributed to the sensory signals, as would occur in conditions of spatiotemporal discre ...
