Optimized Parameter Extraction in Triple Diode Solar PV Models Using Kookaburra‐based Dwarf Mongoose Approach

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Improving photovoltaics (PV) system performance through simulation requires accurate PV models. The nonlinear relationship between current and voltage, coupled with incomplete manufacturer data, presents a significant challenge in parameter estimation.

Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

Metamaterial Polarization Converter Analysis: Limits of Performance

open access: yes, 2012
In this paper we analyze the theoretical limits of a metamaterial converter that allows for linear-to- elliptical polarization transformation with any desired ellipticity and ellipse orientation.

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

open access: yesThe Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

open access: yesLaser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

open access: yesMaterials and Corrosion, EarlyView.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.

High-frequency gate manipulation of a bilayer graphene quantum dot

open access: yes, 2012
We report transport data obtained for a double-gated bilayer graphene quantum dot. In Coulomb blockade measurements, the gate dielectric Cytop(TM) is found to provide remarkable electronic stability even at cryogenic temperatures.

On the Electron Transport in Simplified IBC‐SHJ Solar Cells With MoOx Blanket Layer

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
In this work, we present a study of electron transport through a novel (n)nc‐Si:H/MoOx stack to improve the understanding and performance of simplified IBC‐SHJ solar cells with MoOx blanket layer. The champion solar cell fabricated with the optimized contact stack and metalized with copper electroplating enables efficiencies beyond 23.5%.
