Disagreement in middle ear volume estimation between tympanometry and three-dimensional volume reconstruction in the context of tympanic membrane perforation

open access: yesJournal of Otology, 2017
Introduction: Middle ear volume (MEV) is a clinically relevant parameter across middle ear diseases. MEV values between these techniques have never before been tested for agreement in ears with perforated tympanic membranes (TMs).

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Comparative Analysis of Electron, Proton and Neutron Irradiation Damage in Gallium Arsenide Flexible Triple-Junction Solar Cells

open access: yesEngineered Science
This paper presents a detailed investigation of the effects of 1 MeV electron, 1 MeV neutron, and 3 MeV proton irradiations on the performance of flexible inverted metamorphic GaInP/GaAs/InGaAs triple-junction (IMM3J) solar cells.

Study of neutron spectra in extended uranium target. New experimental data

open access: yesEPJ Web of Conferences, 2017
The spatial distribution of neutron fluences in the extended uranium target (“Quinta” assembly) irradiated with 0.66 GeV proton, 4 AGeV deuteron and carbon beams was studied using the reactions with different threshold energy (Eth).

Directional Flow of Confined Polaritons in CrSBr

open access: yesAdvanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

GEANT4 Target Simulations for Low Energy Medical Applications [PDF]

open access: yes, 2013
The GEANT4 code offers an extensive set of hadronic models for various projectiles and energy ranges. These models include theoretical, parameterized and, for low energy neutrons, data driven models.

Neutron-induced fission cross section of 242Pu from 15 MeV to 20 MeV

open access: yesEPJ Web of Conferences, 2017
Accurate nuclear-data needs in the fast-neutron-energy region have been recently addressed for the development of next generation nuclear power plants (GEN-IV) by the OECD Nuclear Energy Agency (NEA).

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

open access: yesAdvanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Origin of measles virus: divergence from rinderpest virus between the 11th and 12th centuries

open access: yesVirology Journal, 2010
Measles, caused by measles virus (MeV), is a common infection in children. MeV is a member of the genus Morbillivirus and is most closely related to rinderpest virus (RPV), which is a pathogen of cattle.
