The Role of Extracellular Vesicles in Diseases of the Ear, Nose, and Throat

open access: yesMedical Sciences, 2022
Extracellular vesicles (EVs) are membranous nanoparticles produced by most cell types into the extracellular space and play an important role in cell-to-cell communication.

Asymptotic analysis of oscillatory integrals via the Newton polyhedra of the phase and the amplitude

open access: yes, 2012
The asymptotic behavior at infinity of oscillatory integrals is in detail investigated by using the Newton polyhedra of the phase and the amplitude. We are especially interested in the case that the amplitude has a zero at a critical point of the phase ...

Boundary-layer receptivity for a parabolic leading edge [PDF]

open access: yes, 2006
The effect of the nose radius of a body on boundary-layer receptivity is analysed for the case of a symmetric mean flow past a body with a parabolic leading edge.

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Increased nasal tip projection with “pseudo-flaps” using excess lateral cephalic alar cartilage [PDF]

open access: yesRevista Brasileira de Cirurgia Plástica, 2019
Introduction: An increased nasal tip projection is sometimes necessary to achieve an appropriate proportion between nasal tip and dorsum. Numerous techniques and tactics have been described for this purpose using cartilaginous grafts obtained from the ...

OC-163 identification of inflammatory bowel disease (IBD) using field asymmetric ion mobility spectrometry (FAIMS) [PDF]

open access: yes, 2012
Introduction Resident colonic bacteria, principally anaerobes and firmicutes, ferment undigested fibre. The resultant volatile organic compounds (VOCs) formed are dissolved in the faeces but also absorbed and excreted in the urine.

Electronic Nose with Digital Gas Sensors Connected via Bluetooth to a Smartphone for Air Quality Measurements

open access: yesItalian National Conference on Sensors, 2020
This paper introduces a miniaturized personal electronic nose (39 mm × 33 mm), which is managed through an app developed on a smartphone. The electronic nose (e-nose) incorporates four new generation digital gas sensors.

Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

open access: yesAdvanced Functional Materials, EarlyView.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Non-surgical methods for the correction of the hump and the tip of the nose

open access: yesJournal of Education, Health and Sport, 2018
Introduction: It can be said that the nose is the most characteristic element of every face. It occupies one third of the middle part of the face. For this reason, it is very important in creating face profile.

Comparison of 3D printed nose bolus to traditional wax bolus for cost‐effectiveness, volumetric accuracy and dosimetric effect

open access: yesJournal of Medical Radiation Sciences, 2020
Introduction Three‐dimensional printing technology has the potential to streamline custom bolus production in radiotherapy. This study evaluates the volumetric, dosimetric and cost differences between traditional wax and 3D printed versions of nose bolus.
