Hyams Grade and Ki‐67 as Predictive Factors for Primary Treatment Failure in Olfactory Neuroblastoma

open access: yesThe Laryngoscope, EarlyView.
The aim of the present study was to investigate the influence of various prognostic parameters on the occurrence of primary tumor progression and/or tumor recurrence (TPR) in esthesioneuroblastoma after primary curative therapy in a single center. Time to first TPR in esthesioneuroblastoma was significantly shorter in cases with a younger age and ...

Temporal‐Parotid Resection for Malignant Parotid Tumors: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
Parotid gland tumors represent a complex surgical challenge. Temporal‐parotid resection (TPR) is indicated to manage temporal bone invasion. Thirteen studies investigated the role of TPR in literature, including 336 patients. High rates of negative margins and local disease control are achieved with TPR.

Broadband Visible Wavelength Microcomb Generation In Silicon Nitride Microrings Through Air‐Clad Dispersion Engineering

open access: yesLaser &Photonics Reviews, EarlyView.
Air‐clad silicon nitride microring resonators enable visible microcomb generation in wavelength regions where oxide‐clad structures cannot achieve anomalous dispersion. Despite lower quality factors, enhanced nonlinearity from tighter mode confinement allows comb generation at standard pump powers (150 mW).

Room‐Temperature Mid‐Infrared Detection Using Metasurface‐Absorber‐Integrated Phononic Crystal Oscillator

open access: yesLaser &Photonics Reviews, EarlyView.
Room‐temperature mid‐infrared (MIR) detectors are demonstrated using lithium niobate surface acoustic wave phononic crystal oscillators integrated with metasurface absorbers. The devices exhibit rapid thermal response and simplified fabrication compared to suspended resonators.

Combs, Fast and Slow: Non‐Adiabatic Mean‐Field Theory of Active Cavities

open access: yesLaser &Photonics Reviews, EarlyView.
A unified mean‐field theory is developed that describes active cavities with dynamics of any speed, whether they be fast, slow, or anything in between. By creating an operator‐based framework that makes no adiabatic approximation, this approach delivers more efficient simulations and new analytical insights for a wide range of integrated combs, such as
