Bioanalytical TERS and Advanced Data Processing Methods

Journal of Raman Spectroscopy, EarlyView.
Tip‐enhanced Raman spectroscopy delivers label‐free, subnanometer vibrational imaging of biological systems. Recent advances in instrumentation, data analysis, and ambient/liquid operation enable surface‐selective mapping of molecular heterogeneity in proteins, nucleic acids, membranes, and viruses, positioning TERS as a powerful platform for nanoscale

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

Journal of Raman Spectroscopy, EarlyView.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

Journal of Raman Spectroscopy, EarlyView.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Residual Neural Network Compensation of Temperature‐Induced Gamma Shift in OLED Display

Journal of the Society for Information Display, EarlyView.
The figure summarizes the proposed white‐only sensing framework and highlights its key advantages in improving color accuracy and reducing calibration time ABSTRACT Organic light‐emitting diode (OLED) displays exhibit temperature‐induced chromatic shifts and luminance‐dependent nonlinear responses, causing CIEDE2000 color difference (ΔE) and local ...

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

The 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 ...

Cochlear Implantation in Autoimmune Inner‐Ear Disease: Outcome and Patient‐Reported Benefit

The Laryngoscope, EarlyView.
This study demonstrates that patients with secondary autoimmune inner‐ear disease (AIED) achieve significant improvements in speech perception and quality of life following cochlear implantation. Although AIED patients may show slightly lower performance in noisy environments compared to controls, their subjective hearing benefit converges with matched
