Effects of tonotopic matching and spatial cues on segregation of competing speech in simulations of bilateral cochlear implants.

open access: yesPLoS ONE, 2022
In the clinical fitting of cochlear implants (CIs), the lowest input acoustic frequency is typically much lower than the characteristic frequency associated with the most apical electrode position, due to the limited electrode insertion depth.

Oh brother, where art tau? Amyloid, neurodegeneration, and cognitive decline without elevated tau

open access: yesNeuroImage: Clinical, 2021
Mild cognitive impairment (MCI) can be an early manifestation of Alzheimer’s disease (AD) pathology, other pathologic entities [e.g., cerebrovascular disease, Lewy body disease, LATE (limbic-predominant age-related TDP-43 encephalopathy)], or mixed ...

Entropy Density and Mismatch in High-Rate Scalar Quantization with Renyi Entropy Constraint [PDF]

open access: yes, 2012
Properties of scalar quantization with $r$th power distortion and constrained R\'enyi entropy of order $\alpha\in (0,1)$ are investigated. For an asymptotically (high-rate) optimal sequence of quantizers, the contribution to the R\'enyi entropy due to ...

Maximum Power Extraction from a Partially Shaded PV System Using an Interleaved Boost Converter

open access: yesEnergies, 2018
The partially shaded photovoltaic (PSPV) condition reduces the generated power and contributes to hot spot problems that may lead to breakdown of shaded modules. PSPV generates multiple peak, one global one and many other local peaks.

Influence of nocturnal thermal insulation on thermal performance improvement of solar air collector with phase-change material

open access: yesCase Studies in Thermal Engineering, 2023
Solar air collectors (SAC) are widely used for the wintery heating, but they have a mismatch shortcoming between supply and demand periods of heat quantity.

Effect of Technological Mismatch on Photovoltaic Array: Analysis of Relative Power Loss [PDF]

open access: yesJournal of Renewable Energy and Environment, 2021
This study conducts a comparative evaluation of the performance of modules and the arrays under standard test conditions. An equivalent circuit model was developed alongside a computational scheme. The model input data were obtained from the manufacturer’

Effects of mismatched transmissions on two-mode squeezing and EPR correlations with a slow light medium [PDF]

open access: yes, 2005
We theoretically discuss the preservation of squeezing and continuous variable entanglement of two mode squeezed light when the two modes are subjected to unequal transmission.
