Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

open access: yesLaser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Enhanced algorithm for gear calculation for justified selection of materials of gears and wheels

open access: yesIzvestiya MGTU MAMI, 2014
This paper proposes a new improved algorithm for gear calculating allowing justified selection of sizes and heat treatment of the material for manufacture of gears and wheels, considering service life and operational mode. On the basis of the proposed algorithm, a program for gear calculation is developed.

Role of Hearing Loss Genes in the Sensory Epithelia Associated With Meniere Disease

open access: yesSensory Neuroscience, EarlyView.
ABSTRACT Meniere disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, fluctuating sensorineural hearing loss (SNHL), and aural fullness. Its hallmark pathological feature is endolymphatic hydrops. MD shows significant familial clustering in European and East Asian populations, supporting a strong genetic component in ...
