Comparative Analysis of a Super-Wideband Millimeter Wave Array Antenna for Body-Centric Communications

open access: yesInternational Journal of Antennas and Propagation, 2022
The future of wireless technology is moving towards millimeter wave bands due to a surge in the use of wearable gadgets in current wireless bands. The 60 GHz band is unlicensed around the world and has gathered high research interest.

Intraspecific variation in semicircular canal morphology—A missing element in adaptive scenarios?

open access: yesAmerican Journal of Physical Anthropology, 2018
AbstractObjectivesRecent evidence suggests that the amount of intraspecific variation in semicircular canal morphology may, itself, be evidence for varying levels of selection related to locomotor demands. To determine the extent of this phenomenon across taxa, we expand upon previous work by examining intraspecific variation in canal radii and canal ...

Surgical capping of superior semicircular canal dehiscence [PDF]

open access: yes, 2014
Surgical plugging and resurfacing are well established treatments of superior semicircular canal dehiscence, while capping with hydroxyapatite cement has been little discussed in literature.

Numerical and Experimental Study of the Blade Profile of a Savonius Type Rotor Implementing a Multi-Blade Geometry

open access: yesApplied Sciences, 2021
In the present study, the implementation of multi-blade profiles in a Savonius rotor was evaluated in order to increase the pressure in the blade’s intrados and, thus, decrease motion resistance.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Microgravity affects the hair cell ionic currents of the frog semicircular canals [PDF]

open access: yes, 2010
The effects of microgravity on the biophysical properties of frog labyrinthine hair cells have been examined by analyzing calcium and potassium currents in dissociated cells, using the patch-clamp technique.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Beam Performance Optimization of Multibeam Imaging Sonar Based on the Hybrid Algorithm of Binary Particle Swarm Optimization and Convex Optimization

open access: yesInternational Journal of Antennas and Propagation, 2016
It should be noted that the peak sidelobe level (PSLL) significantly influences the performance of the multibeam imaging sonar. Although a great amount of work has been done to suppress the PSLL of the array, one can verify that these methods do not ...

Evolution of arboreality and fossoriality in squirrels and aplodontid rodents: Insights from the semicircular canals of fossil rodents

open access: yesJournal of Anatomy, 2020
Reconstructing locomotor behaviour for fossil animals is typically done with postcranial elements. However, for species only known from cranial material, locomotor behaviour is difficult to reconstruct.

HSV-1 not only in human vestibular ganglia but also in the vestibular labyrinth [PDF]

open access: yes, 2001
Reactivation of herpes simplex virus type 1 (HSV-1) in the vestibular ganglion (VG) is the suspected cause of vestibular neuritis (VN). Recent studies reported the presence of HSV-1 DNA not only in human VGs but also in vestibular nuclei, a finding that ...
