Heading Direction Is Significantly Biased by Preceding Whole-Body Roll-Orientation While Lying

Frontiers in Neurology, 2022
BackgroundAfter a prolonged static whole-body roll-tilt, a significant bias of the internal estimates of the direction of gravity has been observed when assessing the subjective visual vertical.ObjectiveWe hypothesized that this post-tilt bias represents

Influence of reheating on the trispectrum and its scale dependence [PDF]

, 2013
We study the evolution of the non-linear curvature perturbation during perturbative reheating, and hence how observables evolve to their final values which we may compare against observations.

A Coupled SVM-NODE Model for Efficient Prediction of Ship Roll Motion

Journal of Marine Science and Engineering
Traditional analyses of ship roll damping and added moment of inertia rely on free roll decay and forced roll tests, but acquiring linear (small angles) and nonlinear (large angles) relationships demands extensive computational cases and parameter ...

Evolution of Large Scale Curvature Fluctuations During the Perturbative Decay of the Inflaton

, 2007
We study the evolution of cosmological fluctuations during and after inflation driven by a scalar field coupled to a perfect fluid through afriction term. During the slow-roll regime for the scalar field, the perfect fluid is also frozen and isocurvature

Two-Stage Inflation in Supergravity [PDF]

, 1998
We investigate the viability of a two-stage inflationary scenario in the context of supergravity, so as to resolve the problem of initial conditions for hybrid inflation.

Numerical Study on the Effect of Weight Variables on the Roll Damping Coefficients for a Fishing Vessel

Polish Maritime Research
The roll damping coefficient is essential when considering the viscous effect in the potential-based hydrodynamic analysis of fishing vessels; it is an important factor in the roll motion response.

Encyclopaedia Curvatonis [PDF]

, 2015
We investigate whether the predictions of single-field models of inflation are robust under the introduction of additional scalar degrees of freedom, and whether these extra fields change the potentials for which the data show the strongest preference ...

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

Advanced Engineering Materials, EarlyView.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Multi-field open inflation model and multi-field dynamics in tunneling

, 2011
We consider a multi-field open inflation model, in which one of the fields dominates quantum tunneling from a false vacuum while the other field governs slow-roll inflation within the bubble nucleated from false vacuum decay.
