Neck stabilization through sensory integration of vestibular and visual motion cues

open access: yesFrontiers in Neurology, 2023
BackgroundTo counteract gravity, trunk motion, and other perturbations, the human head–neck system requires continuous muscular stabilization. In this study, we combine a musculoskeletal neck model with models of sensory integration (SI) to unravel the ...

A-jump in horizontal inverted semicircular open channels

open access: yesAin Shams Engineering Journal, 2013
The hydraulic jump is a transitional state from supercritical to subcritical flow. The phenomenon of the hydraulic jump has been widely studied because of its frequent occurrence in nature and because of its uses in many practical applications.

Numerical Simulation of Fracturing in Coals Using Water and Supercritical Carbon Dioxide with Potential-Based Cohesive Zone Models

open access: yesGeofluids, 2021
The Park-Paulino-Roesler (PPR) cohesive zone model (CZM) for coal was established for analyzing mixed-mode I/II fractures using semicircular specimens under punch-through shear (PTS) and three-point bending (SCB) tests.

Multidimensional limit theorems for homogeneous sums: a general transfer principle [PDF]

open access: yes, 2015
The aim of the present paper is to establish the multidimensional counterpart of the \textit{fourth moment criterion} for homogeneous sums in independent leptokurtic and mesokurtic random variables (that is, having positive and zero fourth cumulant ...

Partial transpose of random quantum states: exact formulas and meanders [PDF]

open access: yes, 2013
We investigate the asymptotic behavior of the empirical eigenvalues distribution of the partial transpose of a random quantum state. The limiting distribution was previously investigated via Wishart random matrices indirectly (by approximating the matrix

Free Deterministic Equivalents for the Analysis of MIMO Multiple Access Channel [PDF]

open access: yes, 2016
In this paper, a free deterministic equivalent is proposed for the capacity analysis of the multi-input multi-output (MIMO) multiple access channel (MAC) with a more general channel model compared to previous works. Specifically, a MIMO MAC with one base

Locomotor behavior and hearing sensitivity in an early lagomorph reconstructed from the bony labyrinth

open access: yesEcology and Evolution, 2023
The structure of the bony labyrinth is highly informative with respect to locomotor agility (semicircular canals [SCC]) and hearing sensitivity (cochlear and oval windows).
