Phase‐shifted metasurface design for pseudo‐nondiffractive beam deflection
IET Microwaves, Antennas & Propagation, 2022 A transmission phase‐shifted metasurface (PSM) array has been proposed for non‐diffractive beam deflection. A PSM element consists of two identical semicircular rings and an I‐shaped structure, which is symmetrically printed on both sides of the F4B ...

Neck stabilization through sensory integration of vestibular and visual motion cues
Frontiers 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 ...

Partial transposition of random states and non-centered semicircular distributions [PDF]
, 2012 Let W be a Wishart random matrix of size d^2 times d^2, considered as a block matrix with d times d blocks. Let Y be the matrix obtained by transposing each block of W.

On the semicircular law of large dimensional random quaternion matrices [PDF]
, 2015 It is well known that Gaussian symplectic ensemble (GSE) is defined on the space of $n\times n$ quaternion self-dual Hermitian matrices with Gaussian random elements. There is a huge body of literature regarding this kind of matrices.

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

A-jump in horizontal inverted semicircular open channels
Ain 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.

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