Beam Squint in Ultra-wideband mmWave Systems: RF Lens Array vs. Phase-Shifter-Based Array [PDF]

, 2022
In this article, we discuss the potential of radio frequency (RF) lens for ultra-wideband millimeter-wave (mmWave) systems. In terms of the beam squint, we compare the proposed RF lens antenna with the phase shifter-based array for hybrid beamforming. To

Squint Among Adult Population in Hail City, Saudi Arabia [PDF]

, 2018
Background: Strabismus, also known as crossed eyes, is a condition in which the eyes do not properly align with each other when looking at an object. If present during a large part of childhood, it may result in amblyopia.

Postoperative outcomes and predictors of functional sequelae following hemispheric surgery in Rasmussen's encephalitis: A retrospective cohort study from the global pediatric epilepsy surgery registry

Epileptic Disorders, EarlyView.
Abstract Objective Rasmussen's encephalitis (RE) is a rare and progressive, immune‐mediated epileptic encephalopathy characterized by drug‐resistant seizures and neurological decline. While hemispheric disconnection (HD) is the gold standard treatment for effective seizure control, this procedure carries significant risk of permanent neurological ...

Reduction of squint in the slant polarised phased array antennas

, 2017
The nature of the squint problem in the electrically tilted phased arrays (e.g. base transceiver station antennas) is explored based on the antenna theory and array theory.

Beyond Skin and Eyes: The Medical and Social Burden of Oculocutaneous Albinism in Africa: A Narrative Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

Laser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Congenital Intraoral Synechiae: A Scoping Review of Airway, Feeding, and Surgical Management

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To map the existing literature on congenital intraoral synechiae and summarize reported anatomic patterns, clinical presentation, associated anomalies/syndromes, and outcomes to inform standardized diagnostic and therapeutic approaches. Data Sources PubMed, CINAHL, Embase, Web of Science, and Google Scholar were searched from January

Managing Robot Perception: How Families Present Their Faces to a Toy Robot

Symbolic Interaction, EarlyView.
Playing with a robot's face detection capabilities constitutes a praxeological approach to learning about new technology. We explore how family members discover suitable formations for a Cozmo robot to scan a single face, drawing on video recordings from Swedish homes. Taking an ethnomethodology and conversation‐analysis perspective, we demonstrate how

SQUINT-A NONLINEAR FEATURE OF FLOW PATTERNS IN NEMATICS

, 1979
The curvature ψ of an electronematodynamic flow pattern obeys, in the steady state, the nonlinear equation ψ'' + q2 ψ - ψ3 + bψψ' = 0. The term ψψ', called squint, is studied. Squint originates in the distortion torque and the distortion stress.
