We demonstrate 10Gbit/s operation of two different types of monolithic photocurrent driven wavelength converters (PD-WC). These photonic integrated circuits use a Semiconductor Optical Amplifier (SOA)-PIN photodetector receiver to drive an Electro-absorption (EA), or Mach-Zehnder (MZ) modulator that is integrated with a SGDBR tunable laser. We demonstrate improvements in optical bandwidth, inse...

We propose a novel ultracompact (5 μm) hybrid plasmonic polarization rotator operating at telecommunication wavelength for integrated silicon photonic circuits. The polarization mode of a silicon waveguide is rotated with >14 dB polarization extinction ratio and low total insertion losses of 2.1 dB.

background: primary stability is an important factor for the clinical success of orthodontic mini-screws. the present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws. materials and methods: in this experimental study, 72 mini-screws (dual top anchor system, jeil, 1.6 mm diameter, 8 mm length) were use...

The mai...

Cybersecurity breaches may be correlated due to geography, similar infrastructure, or use of a third-party contractor. We show how logistic regression used estimate the probability an attack where among firms up and down supply chain. also Poisson number records breached. Losses arising from cybersecurity have unknown distribution. propose stock price reaction breach as objective measure loss i...

A novel compact wideband (2-12 GHz) Wilkinson equal power divider on microstrip line is proposed in this paper. In this paper, a novel approach to the design of a Wideband (2-12) power divider is presented. In order to achieve the wideband performance, the divider is established by introducing variable width of microstrip line between input lines to output lines of different impedance. Finally,...

background carbapenemes are a good choice for treatment of infections caused by multidrug resistant pseudomonads aeruginosa. the emergence of carbapenem resistance has become a major problem in treatment of this organism especially among immunocompromised patients including burn patients. objectives the aim of this study was to investigate carbapenem-resistance mechanisms among burn patients in...

BACKGROUND In 2001, 6.3 million passengers were involved in motor vehicle crashes. This study aimed to determine the number of work days lost as a result of motor vehicle crashes and factors that influenced people's return to work. METHODS This was a retrospective, population based cohort study of occupants in motor vehicles involved in crashes from the 1993-2001 Crashworthiness Data System p...
