A study of the nerve root damage in whiplash injury occurrence mechanisms using human head-neck finite element model

open access: yesNihon Kikai Gakkai ronbunshu, 2021
The number of whiplash injuries in rear-end collisions is still high worldwide. Since the 1990s, many researchers have studied the mechanisms of injury occurrence in which were focused in the early stage of the rear impact. However, the current situation

Characterization of PECVD Silicon Nitride Photonic Components at 532 and 900 nm Wavelength [PDF]

open access: yes, 2014
Low temperature PECVD silicon nitride photonic waveguides have been fabricated by both electron beam lithography and 200 mm DUV lithography. Propagation losses and bend losses were both measured at 532 and 900 nm wavelength, revealing sub 1dB/cm ...

Enzyme-ultracytochemical study of adenylate and guanylate cyclases in normal and pathologic human nasal mucosa

open access: yesEuropean Journal of Histochemistry, 2009
The ultracytochemical localization of adenylate cyclase (AC) and guanylate cyclase B (GC-B) and C (GC-C) activity was studied after stimulation with pituitary adenylate cyclase activating peptide, C-type natriuretic peptide and guanylin, respectively, in

Silicon implantation in GaAs [PDF]

open access: yes, 1979
The electrical properties of room-temperature Si implants in GaAs have been studied. The implantations were done at 300 keV with doses ranging from 1.7×10^13 to 1.7×10^15 cm^–2.

Quasimodularity and large genus limits of Siegel-Veech constants

open access: yes, 2018
Quasimodular forms were first studied in the context of counting torus coverings. Here we show that a weighted version of these coverings with Siegel-Veech weights also provides quasimodular forms.

On the classical r-matrix structure of the rational BCn Ruijsenaars–Schneider–van Diejen system

open access: yesNuclear Physics B, 2015
In this paper, we construct a quadratic r-matrix structure for the classical rational BCn Ruijsenaars–Schneider–van Diejen system with the maximal number of three independent coupling parameters.
