Human Pegivirus Encephalitis With Brain Detection and Response to Sofosbuvir Ledipasvir
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Human pegivirus (HPgV‐1) has been associated with severe encephalomyelitis in immunocompromised patients. Its neurological spectrum remains poorly defined. We report a slowly progressive encephalitis in a person living with well‐controlled HIV, characterized by white matter abnormalities and inflammatory cerebrospinal fluid (CSF). HPgV RNA was

Mid-infrared photonics devices in SOI
In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm

A multi-port optical microfiber coil resonator
A new type of multi-port optical microfiber resonator is presented. The coupler-based coil resonator was fabricated by coiling a four port microfiber coupler around a low index support rod and then embedding the resulting device in a low refractive index

Precise fabrication of coupled ring-resonator structures
, 2009 We report improvements in fabrication precision obtained in coupled ring-resonator slow-wave structures on an SOI platform. Optical delay lines were formed by using a cascade of coupled resonant cavities to slow the propagation of light through the ...
