A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]
, 2003 Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

Padrão radiológico da otosclerose coclear. Estudo por TC de 14 doentes.
Acta Médica Portuguesa, 1994 In this review of cochlear otosclerosis 14 cases were studied by CT scan aiming to establish a densitometric pattern of the capsular foci and relating it to the hearing and vestibule dysfunctions.

Braincase anatomy of the Paleocene crocodyliform Rhabdognathus revealed through high resolution computed tomography [PDF]
PeerJ, 2021 Dyrosaurids were highly specialized, largely marine, relatives of living crocodylians, and one of the few archosaur lineages to survive the K-Pg extinction.

Faster and safer evacuations induced by closed vestibules [PDF]
arXiv, 2022 Improving emergency evacuations is a top priority in human safety and in pedestrian dynamics. In this paper, we use the social force model, in order to optimize high-anxiety pedestrian evacuations. We explore two architectural layouts, the 1-door vestibule, and the 2-doors vestibule.

On the length of arcs in labyrinth fractals [PDF]
Cristea, L.L. & Leobacher, G. Monatsh Math (2018) 185: 575, 2018 Labyrinth fractals are self-similar dendrites in the unit square that are defined with the help of a labyrinth set or a labyrinth pattern. In the case when the fractal is generated by a horizontally and vertically blocked pattern, the arc between any two points in the fractal has infinite length [Cristea\&Steinsky 2009,Cristea\&Steinsky 2011].

The vestibular contribution to the head direction cells signal and navigation
Frontiers in Integrative Neuroscience, 2014 Spatial learning and navigation depend on neural representations of location and direction within the environment. These representations, encoded by place cells and head direction cells, respectively, are dominantly controlled by visual cues, but ...

Improving competitive evacuations with a vestibule structure designed from panel-like obstacles [PDF]
arXiv, 2021 It has been shown that placing an obstacle in front of an exit door has proven to be a successful method to improve pedestrian evacuations. In this work, we will focus on the space limited by the exit and the obstacles (i.e. the vestibule structure).

Labyrinth chaos: Revisiting the elegant, chaotic and hyperchaotic walks [PDF]
, 2020 Labyrinth chaos was discovered by Otto R\"ossler and Ren\'e Thomas in their endeavour to identify the necessary mathematical conditions for the appearance of chaotic and hyperchaotic motion in continuous flows. Here, we celebrate their discovery by considering a single labyrinth walks system and an array of coupled labyrinth chaos systems that exhibit ...

Preferential Cochleotoxicity of Cisplatin
Frontiers in Neuroscience, 2021 Cisplatin-induced ototoxicity in humans is more predominant in the cochlea than in the vestibule. Neither definite nor substantial vestibular dysfunction after cisplatin treatment has been consistently reported in the current literature.

Quadrilateral Labyrinth Fractals [PDF]
arXiv, 2021 In this paper, a class of fractals, called quadrilateral labyrinth fractals, are introduced and studied. They are a special kind of fractals on any quadrilateral on the plane. This type of fractal is motivated by labyrinth fractal on the unit square and triangle, which were already studied. This paper mainly deals with the construction of quadrilateral
