A 77-118 GHz Resonance-free Septum Polarizer [PDF]

open access: yesYen-Lin Chen et al. 2014, ApJS, 211, 11, 2014
Measurements of the polarized radiation often reveal specific physical properties of emission sources, such as strengths and orientations of magnetic fields offered by synchrotron radiation and Zeeman line emission, and the electron density distribution by free-free emission.

Machine learning of endoscopy images to identify, classify, and segment sinonasal masses

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background We developed and assessed the performance of a machine learning model (MLM) to identify, classify, and segment sinonasal masses based on endoscopic appearance. Methods A convolutional neural network‐based model was constructed from nasal endoscopy images from patients evaluated at an otolaryngology center between 2013 and 2024 ...

A study of vowel nasalization using instantaneous spectra [PDF]

open access: yesarXiv, 2020
Nasalization of vowels is a phenomenon where oral and nasal tracts participate simultaneously for the production of speech. Acoustic coupling of oral and nasal tracts results in a complex production system, which is subjected to a continuous changes owing to glottal activity.

Unilateral Versus Bilateral Endoscopic Resection of Olfactory Neuroblastoma: Pooled Analysis From Prospective and Retrospective Multicenter Data

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however ...

Reassessment of the basis of cell size control based on analysis of cell-to-cell variability [PDF]

open access: yes, 2019
Fundamental mechanisms governing cell size control and homeostasis are still poorly understood. The relationship between sizes at division and birth in single cells is used as a metric to categorize the basis of size homeostasis [1-3]. Cells dividing at a fixed size regardless of birth size (sizer) are expected to show a division-birth slope of 0 ...

Measuring Cognitive Load of Software Developers Based on Nasal Skin Temperature [PDF]

open access: yesarXiv, 2022
It has recently become increasingly important to measure the cognitive load of developers. This is because continuing with a development under a high cognitive load may cause human errors. Therefore, to automatically measure the cognitive load, existing studies have used biometric measures such as brain waves and the heart rate. However, developers are

Empirical Analysis of Oral and Nasal Vowels of Konkani [PDF]

open access: yesarXiv, 2023
Konkani is a highly nasalised language which makes it unique among Indo-Aryan languages. This work investigates the acoustic-phonetic properties of Konkani oral and nasal vowels. For this study, speech samples from six speakers (3 male and 3 female) were collected.

Differential Immune Cell Infiltration in Eosinophilic and Non‐Eosinophilic CRS: Correlations With Clinical, Endoscopic, and Radiological Findings

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The pathogenesis of inflammation in eosinophilic chronic rhinosinusitis (ECRS) and non‐eosinophilic chronic rhinosinusitis (NECRS) remains poorly understood. This study aimed to assess immune cell infiltration within the sinonasal microenvironment in these conditions.
