Controlled multiple spectral hole burning via a tripod-type atomic medium

New Journal of Physics
In limit of saturation spectroscopy, we theoretically study the spectral hole burning (SHB) in the absorption spectrum of a probe field through a tripod atomic system. The response function for the probe field is calculated in a Doppler-broadened medium.

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

New Photonic System for Optical Packet Switching [PDF]

Journal of Systemics, Cybernetics and Informatics, 2003
Fast optical switching (ms timebase) is realized by using a RF frequency tone inserted in the optical packet that carries a digital payload. By using a highly selective RF filtering for optical packet header frequency recognition, we have obtained ...

All-Optical Switching and Router via the Direct Quantum Control of Coupling between Cavity Modes

Physical Review X, 2013
In this work, we describe a scheme to execute all-optical control of the routing or switching of photonic information where, by optically controlling the internal quantum state of a individual scatterer coupled to two independent cavity modes, one can ...

Investigation of the Thermal Sensitive Spectral Response of Chalcogenide Fiber Bragg Grating

Communications, 2013
This contribution presents numerical studies of the nonlinear fiber Bragg grating (FBG). The proposed model corresponds well to chalcogenide FBG as a considerable tool for optical switching. The spectral response of this device is discussed theoretically.

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.

Ultrafast defect dynamics: A new approach to all optical broadband switching employing amorphous selenium thin films

AIP Advances, 2015
Optical switches offer higher switching speeds than electronics, however, in most cases utilizing the interband transitions of the active medium for switching. As a result, the signal suffers heavy losses. In this article, we demonstrate a simple and yet

Comparative Effectiveness and Safety of Inebilizumab Versus Rituximab in AQP4‐IgG‐Positive NMOSD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rituximab (anti‐CD20, RTX) and inebilizumab (anti‐CD19, INE) represent B‐cell‐depleting therapies used for aquaporin‐4 antibody‐positive (AQP4‐IgG+) neuromyelitis optica spectrum disorder (NMOSD); however, direct comparative evidence remains limited.

Ultrafast Electric Switching of Brookite TiO2 Nanorods with a Permanent Dipole Moment at High Concentrations

Advanced Materials Interfaces
Transient electric birefringence measurements are used to show that brookite titania nanorods dispersed in the apolar liquid butylbenzene possess a large permanent dipole moment of 516 debye (rod length: 39 nm, diameter: 4.1 nm). This dipole moment makes

Modeling an Optical Network Operating with Hybrid-Switching Paradigms

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
The continuous increasing of the Internet traffic has brought serious concerns about capacity exhaustion of the optical infrastructure in a medium term horizon. Taking into account the optical networks, comprising the Internet backbone, the strategies to
