Channel Estimation for Wideband Multi-RIS-Assisted mmWave Massive-MIMO OFDM System With Beam Squint Effect

open access: yesIEEE Open Journal of the Communications Society
Reconfigurable intelligent surfaces (RISs) and massive multiple-input multiple-output (massive-MIMO) systems are promising technologies for improving the energy efficiency of millimeter-wave (mmWave) communication.

The role of pain in Graves' orbitopathy: Associations with clinical activity and quality of life

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Pain is included in the clinical activity score (CAS) as an indicator of inflammatory activity in Graves' orbitopathy (GO), yet its clinical relevance has not been systematically evaluated. We therefore investigated the relationship between pain, other inflammatory signs and quality of life (QoL), and assessed the effect of intravenous

Clinical manifestations of dual‐gene variants in retinitis pigmentosa

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Retinitis pigmentosa (RP) is an inherited retinal disease (IRD), whereby each affected individual typically harbours pathogenic variants in a single causative gene, yet the disorder exhibits marked genetic heterogeneity, with more than 100 genes reported to underlie RP.

Comparison of ocular response analyzer parameters in primary open angle glaucoma and exfoliative glaucoma patients

open access: yesIndian Journal of Ophthalmology, 2014
Aim: We sought to identify differences in the following measures of the ocular response analyser (ORA) between primary open angle glaucoma (POAG) and exfoliative glaucoma (EXG) patients: Corneal hysteresis (CH), corneal resistance factor (CRF), corneal ...

Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.
