Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...

We demonstrate for the first time WDM multi-path routing through a monolithically integrated InP/InGaAsP 8 × 8 space and wavelength selective cross-connect. Data channels are dynamically routed from four input ports to the same output port with excellent OSNR from 27.0 to 31.1 dB. Representative data paths are evaluated in terms of optical power penalty. Data routing experiments are performed u...

objective: better understanding of the furcation anatomy may serve to decrease the risk of root perforation. the purpose of this study was to measure the thickness of root walls in the danger zone in mandibular first molars. materials and methods: the roots of 53 extracted human mandibular first molars were sectioned in the horizontal plane 4 mm below the orifice of the mesial and distal root c...

objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...

Wavelength-division-multiplexing (WDM) networks with wide channel grids and bandwidths are promising for low-cost, low-power optical interconnects. Wide-bandwidth, single-band (i.e., no free-spectral range) add-drop filters have been developed on silicon using anti-reflection contra-directional couplers with out-of-phase Bragg gratings. Using such filter components, we demonstrate a 4-channel, ...

We propose and demonstrate 10-Gb/s broadcast signal transmission in a wavelength-division-multiplexing passive optical network (WDM-PON) by employing a modular-type mutually injected Fabry-Perot laser diodes (MI F-P LDs) as a cost-effective multi-wavelength light source (MWS). We introduce a simple interferometric noise suppression technique with proper electrical filtering to improve transmiss...

We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...
