Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.

Parity-time symmetry in wavelength space within a single spatial resonator
Nature Communications, 2020 Most conventional PT-symmetric systems contain two physically separated modes. Here the authors proposed a PT-symmetric microwave optoelectronic oscillator, where the gain and loss modes are confined in a single spatial resonator, resulting in an ...

An Out‐of‐Place Etiology: Recognizing FMR1 Premutation in the Memory Clinic
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT The FMR1 gene premutation (55–200 CGG repeats) is usually associated with a wide range of symptoms and phenotypes within the Fragile X‐tremor/ataxia syndrome (FXTAS), but may also manifest as predominant or isolated cognitive decline. We describe three male patients referred for progressive cognitive impairment and behavioral changes. Standard

Rayleigh Fading Suppression in One-Dimensional Optical Scatters
IEEE Access, 2019 A highly coherent wave is favorable for applications in which phase retrieval is necessary, yet a high-coherence wave is prone to encounter Rayleigh fading phenomenon as it passes through a medium of random scatters.

Longitudinally-graded optical fibers
Optics Express, 2012 Optical fibers have become ubiquitous tools for the creation, propagation, manipulation, and detection of light. However, while the intensity of light propagating through the fiber can increase or decrease along the length through amplification or attenuation, respectively, the properties of the fiber itself generally do not, thus removing an ...
