Rotman lens-based two-tier hybrid beamforming for wideband mmWave MIMO-OFDM system with beam squint

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
In this paper, we study the hybrid beamforming for the wideband mmWave multiuser MIMO-OFDM system. We characterize the frequency-dependent beam angle problem, i.e., beam squint effect. Firstly, we extend the mmWave channel model from the Saleh-Valenzuela

High‐Resolution Genomic Characterization of WAGR Spectrum Disorder: Insights From a Novel Cohort and Literature Synthesis, and Validation of Patient‐Reported Data

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT WAGR spectrum disorder (WAGRSD) is an ultra‐rare congenital disorder caused by heterozygous deletion of chromosome 11p13. While classically associated with Wilms tumor, Aniridia, Genitourinary anomalies, and a Range of developmental delays, accurate delineation of the deletion is critical for prognosis because the phenotypic spectrum extends ...

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Descriptive Epidemiology From the Myhre Syndrome Foundation Registry: The Value of Self‐Reported Data

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is an ultrarare genetic disease characterized by short stature, distinct craniofacial features, cardiovascular and respiratory fibrosis and stenosis, neurodevelopmental delays, autism, intellectual disability, and hearing loss. The natural history of Myhre syndrome is still not fully understood due to a small patient population ...

Safety and Perioperative Outcomes of Immediate Versus Delayed Sequential Bilateral Cataract Surgery in the Pediatric Population: A Systematic Review and Meta‐Analysis

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Background Bilateral congenital cataracts are a major cause of preventable childhood blindness. Although delayed sequential bilateral cataract surgery (DSBCS) has traditionally been the preferred approach, immediate sequential bilateral cataract surgery (ISBCS) is increasingly being considered to reduce anesthesia exposure and healthcare ...

Two-Dimensional Autofocus for Ultra-High-Resolution Squint Spotlight Airborne SAR Based on Improved Spectrum Modification

open access: yesRemote Sensing
For ultra-high-resolution (UHR) squint spotlight airborne synthetic aperture radar (SAR), the severe range-azimuth coupling caused by squint mode and the spatial and frequency dependence of the motion error brought by ultra-wide bandwidth both make it ...

On the infrared scaling solution of SU(N) Yang-Mills theories in the maximally Abelian gauge

open access: yes, 2010
An improved method for extracting infrared exponents from functional equations is presented. The generalizations introduced allow for an analysis of quite complicated systems such as Yang-Mills theory in the maximally Abelian gauge.
