Neuromyelitis optica

open access: yesThe Indian Anaesthetists Forum, 2021
Neuromyelitis optica (NMO), a rare devastating demyelinating syndrome involving optic neuritis and myelitis, poses a challenge to anesthesiologists. Here, we present the anesthetic management of a diagnosed case of NMO posted for total hip replacement.

Deep-learning-enabled electromagnetic near-field prediction and inverse design of metasurfaces

open access: yes, 2023
Metasurfaces generate desired electromagnetic wavefronts using sub-wavelength structures that are much thinner than conventional optical tools.However, their typical design method is based on trial and error, which is adversely inefficient in terms of ...

Pre-Lens Tear Meniscus Height, Lipid Layer Pattern and Non-Invasive Break-Up Time Short-Term Changes with a Water Gradient Silicone Hydrogel Contact Lens

open access: yesLife, 2022
To evaluate pre-lens tear film volume, stability and lipid interferometry patterns with a silicone hydrogel water content contact lens, a novel, noninvasive, ocular-surface-analyzer technology was used.

The history of neuromyelitis optica [PDF]

open access: yesJournal of Neuroinflammation, 2013
The discovery of a novel serum autoantibody (termed NMO-IgG or AQP4-Ab) in a subset of patients in 2004 has revived interest in neuromyelitis optica (NMO). While the history of classical multiple sclerosis has been extensively studied, only little is known about the history of NMO.

New Two-Dimensional Materials Obtained by Functionalization of Boron Graphdiyne Layers with Nickel

open access: yesNanomaterials
The decoration of hexagonal boron graphdiyne (BGDY) layers with Ni atoms has been investigated by density functional calculations. For one, two, and three Ni atoms per hexagon, the BGDY structure is approximately maintained.

Symmetry Groups, Quantum Mechanics and Generalized Hermite Functions

open access: yesMathematics, 2022
This is a review paper on the generalization of Euclidean as well as pseudo-Euclidean groups of interest in quantum mechanics. The Weyl–Heisenberg groups, Hn, together with the Euclidean, En, and pseudo-Euclidean Ep,q, groups are two families of groups ...

High-flux single-photon lidar [PDF]

open access: yes, 2021
In time-correlated single-photon counting (TCSPC), photons that arrive during the detector and timing electronics dead times are missed, causing distortion of the detection time distribution.

Dual-Band Uniaxial Dielectric Anisotropy Sensor Using Coupled-Line Resonators

open access: yesIEEE Access, 2023
In this paper, a new dual-band sensor to measure uniaxial anisotropy at two frequency bands is proposed. This sensor is composed of two dual-mode resonators separated by a T-shaped structure implemented in microstrip technology.
