Interaction of supernova blast waves with wind-driven shells: formation of "jets", "bullets", "ears", etc [PDF]

Odessa Astron. Publ., 12 (1999) 117, 1999
Most of middle-aged supernova remnants (SNRs) have a distorted and complicated appearance which cannot be explained in the framework of the Sedov-Taylor model. We consider three typical examples of such SNRs (Vela SNR, MSH 15-52, G 309.2-00.6) and show that their structure could be explained as a result of interaction of a supernova (SN) blast wave ...

Realistic 3D computer model of the gerbil middle ear, featuring accurate morphology of bone and soft tissue structures [PDF]

arXiv, 2011
In order to improve realism in middle ear (ME) finite element modeling (FEM), comprehensive and precise morphological data are needed. To date, micro-scale X-ray computed tomography (\mu CT) recordings have been used as geometric input data for FEM models of the ME ossicles.

Cochlear detection of double-slip motion in cello bowing [PDF]

arXiv, 2018
A double-slip motion of a cello sound is investigated experimentally with a bowing machine and analyzed using a Finite-Difference Time Domain (FDTD) cochlear model. A double-slip sound is investigated. Here the sawtooth motion of normal bowing is basically present, but within each period the bow hair tears off the strings once more within the period ...

Etat de l'art des systèmes robotisés en vue d'une application pour la chirurgie otologique [PDF]

arXiv, 2019
This article deals with a patents state-of-the-art linked to our robotic system which holds an endoscope. In a first part, we analyze how the endoscope operates as well as we discover the environment where we wish to use it: the middle ear. In a second step, we establish a state-of-the-art on patents existing in the robotic and surgical fields.

Self-supervised Mamba-based Mastoidectomy Shape Prediction for Cochlear Implant Surgery [PDF]

arXiv
Cochlear Implant (CI) procedures require the insertion of an electrode array into the cochlea within the inner ear. To achieve this, mastoidectomy, a surgical procedure involving the removal of part of the mastoid region of the temporal bone using a high-speed drill provides safe access to the cochlea through the middle and inner ear. In this paper, we
