Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

open access: yesJournal of Raman Spectroscopy, EarlyView.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Early Spectral Resolution Predicts Later Speech Recognition in Adult Cochlear Implant Recipients

open access: yesThe Laryngoscope, EarlyView.
In 531 ears from 498 adult cochlear implant recipients, spectral modulation detection (EasyQSMD) stabilized within 1 week post‐activation and significantly predicted later speech recognition outcomes. Early spectral resolution thresholds can identify potential poor performers during the critical first month, enabling earlier implementation of targeted ...

Attrition in Cochlear Implant Research: Sociodemographic, Audiologic, and Performance Variables

open access: yesThe Laryngoscope, EarlyView.
In a retrospective review of attrition patterns for participants in a clinical research study, sociodemographic variables were not significantly different between those who elected to withdraw and those who completed the study. Those in the withdrawal group had poorer low‐frequency residual hearing, were less likely to be electric‐acoustic stimulation ...

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.
