150-Channel Four Wave Mixing Based Multiwavelength Brillouin-Erbium Doped Fiber Laser

open access: yesIEEE Photonics Journal, 2013
A wide band tunable multiwavelength Brillouin-erbium fiber laser (BEFL) is developed. In this structure, the laser is formed between a double pass amplification box and a highly nonlinear fiber (HNLF), which acts as a virtual mirror, results in removing ...

Triangular Index Ratio as an Alternative Method to the Alpha Angle for Defining the Presence of Cam Morphology: A Prospective Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Cam morphology, which is a significant risk factor for hip osteoarthritis, is commonly quantified by the alpha angle (AA). This study aims to explore the potential of the triangular index ratio (TIR) to quantify cam morphology on anteroposterior radiographs by assessing the association between TIR‐defined cam morphology and the development of

IEEE 802.15.3c WPAN Standard Using Millimeter Optical Soliton Pulse Generated by a Panda Ring Resonator

open access: yesIEEE Photonics Journal, 2013
A system of microring resonators (MRRs) connected to an optical modified add/drop filter system known as a Panda ring resonator is presented. The optical soliton pulse of 60 GHz frequency band can be generated and used for Wireless Personal Area Network (

On Kreĭn's formula

open access: yesJournal of Mathematical Analysis and Applications, 2009
Let \(A_0\) be a fixed selfadjoint extension of a closed symmetric operator \(S\) on a Hilbert space \(\mathfrak H\). The well-known Kreǐn formula \[ P_{\mathfrak H}(\tilde A-\lambda)^{-1}\big|{\mathfrak H}=(A_0-\lambda)^{-1}-\gamma(\lambda)\bigl(M(\lambda)+\tau)(\lambda)\bigr)^{-1}\gamma(\overline{\lambda})^* \] gives a description of the compressed ...

Real‐World Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

Data-Aided OSNR Estimation for QPSK and 16-QAM Coherent Optical System

open access: yesIEEE Photonics Journal, 2013
We propose an optical signal-to-noise ratio (OSNR) estimation technique using self-equalized complementary Golay sequences for both QPSK and 16-QAM coherent optical systems. The training sequences have complementary spectra, which enable accurate channel
