BACKGROUND: The purpose of this study was to determine the indications for implantation
of the coflex device (Paradigm Spine, LLC, New York, New York), assess long-term …

The purpose of this study was to determine the safety and efficacy of the coflex® interspinous
implant in patients between the ages of 40 and 80 years old with the primary diagnosis of …

BACKGROUND CONTEXT: Degenerative spinal stenosis is a severely disabling disease
common in the elderly with patient symptoms usually including bilateral radicular pain that …

We first optimize the design and compare the performance of thermo-optic phase-shifters
based on TiN metal and N_++ doped silicon, in the same SOI process. The designs don’t …

We characterize the impact of the modulator material on chirp, digital signal processing (DSP)
algorithms and system-level performance in coherent digital optical links. We compare …

In this paper, we present inphase-quadrature (IQ) modulation in the O-band using dual parallel
Mach-Zehnder modulators on the silicon photonics platform. The detailed design of the …

We propose and experimentally demonstrate low-power and broadband variable optical
attenuators (VOAs) on the silicon photonics platform. The VOAs are based on a Mach-Zehnder …

We demonstrate an optical time-gate isolator entirely fabricated on the silicon-on-insulator (SOI)
platform based on a conventional traveling-wave Mach-Zehnder modulator (TW-MZM) …

… It was first invented in 1994 by the French orthopaedic surgeon Jacques Samani as an
alternative to arthrodesis, in order to protect adjacent levels after spinal surgery and for the …

… Jacques Samani in 1994 and has been in continuous use (more than 40,000 cases) since
that time outside the United States. The device is placed between two adjacent spinous …
