A Compact Four-Port MIMO Antenna for UWB Applications

Sensors, 2022
A compact four-port multiple-input multiple-output (MIMO) antenna for ultrawideband (UWB) applications is presented in this paper. The proposed antenna has four unit cell antennas. Each unit cell is placed orthogonal to its adjacent elements.

A Wide Frequency Scanning Printed Bruce Array Antenna with Bowtie and Semi-Circular Elements

Sensors, 2020
A printed edge-fed counterpart of the wire Bruce array antenna, for frequency scanning applications, is presented in this paper. The unit-cell of the proposed antenna consists of bowtie and semi-circular elements to achieve wide bandwidth from below 22 ...

On the enigma of Palaenigma wrangeli (Schmidt), a conulariid with a partly non-mineralized skeleton [PDF]

PeerJ, 2021
Palaenigma wrangeli (Schmidt) is a finger-sized fossil with a tetraradiate conical skeleton; it occurs as a rare component in fossiliferous Upper Ordovician strata of the eastern Baltic Basin and is known exclusively from north Estonia.

Primes in Intervals and Semicircular Elements Induced by p-Adic Number Fields Q p over Primes p

Mathematics, 2019
In this paper, we study free probability on (weighted-)semicircular elements in a certain Banach *-probability space ( LS , τ 0 ) induced by measurable functions on p-adic number fields Q p over primes p .

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 ...

Spatiotemporal symmetries in the disynaptic canal-neck projection [PDF]

, 2007
The vestibular system in almost all vertebrates, and in particular in humans, controls balance by employing a set of six semicircular canals, three in each inner ear, to detect angular accelerations of the head in three mutually orthogonal coordinate ...
