Mode division multiplexing (MDM) is a promising technology for increasing the aggregate bandwidth of multimode fiber (MMF) in conjunction with wavelength division multiplexing (WDM) in face of the impending capacity crunch in optical fiber networks. This paper investigates the effect of radial and azimuthal mode spacings in a 25-channel MDM-WDM system in MMF using a spatial light modulator-cont...

The frequency of various anomalies was compared in probands with Fanconi anaemia and their affected sibs. As probands are usually ascertained because of a 'characteristic' array of physical anomalies, the frequencies of these specific anomalies may be overestimated in probands, whereas their affected sibs may provide a more accurate estimate. The frequencies of growth retardation, skin hyperpig...

We describe and characterize a 25 GHz laser frequency comb based on a cavity-filtered erbium fiber mode-locked laser. The comb provides a uniform array of optical frequencies spanning 1450 nm to 1700 nm, and is stabilized by use of a global positioning system referenced atomic clock. This comb was deployed at the 9.2 m Hobby-Eberly telescope at the McDonald Observatory where it was used as a ra...

A radial p-n junction solar cell based on vertically free-standing silicon nanowire (SiNW) array is realized using a novel low-temperature and shallow phosphorus doping technique. The SiNW arrays with excellent light trapping property were fabricated by metal-assisted chemical etching technique. The shallow phosphorus doping process was carried out in a hot wire chemical vapor disposition chamb...

The microtubule- and centrosome-associated Ste20-like kinase (SLK; long Ste20-like kinase [LOSK]) regulates cytoskeleton organization and cell polarization and spreading. Its inhibition causes microtubule disorganization and release of centrosomal dynactin. The major function of dynactin is minus end-directed transport along microtubules in a complex with dynein motor. In addition, dynactin is ...

Two jets from the Orion (M42) 'proplyds' – kinematics, morphologies and origins. ABSTRACT A spatially unresolved velocity feature, with an approaching radial velocity of ≈ 100 km s −1 with respect to the systemic radial velocity, in a position–velocity array of [O iii] 5007Å line profiles is identified as the kinematical counterpart of a jet from the proplyd LV 5 (158–323) in the core of the Or...

background: the present study was designed to ascertain serial changes on distal radius radiographic parameters attributable to aging.       methods: in this prospective study, the sample consisted of 120 healthy individuals who were divided into four age groups each containing 15 males and 15 females. in the two below-20-year-old groups, only ulnar variance could be investigated. wrist radiogr...

The rst micromachined bimorph organic ciliary array with on-chip CMOS circuitry is presented. This device is composed of an 8 8 array of cells each having four orthogonally oriented actuators in an overall die size of 9:4mm 9:4mm. The polyimide based actuators were fabricated directly above the selection and drive circuitry. Selection and activation of actuators in this array shows that integra...

It is well known that to perform accurate Direction of Arrivals (DOA) estimation using algorithms like MUSIC (MUltiple SIgnals Classification), antenna array data must be calibrated to match the theoretical model upon which DOA algorithms are based. This paper presents experimental measurements from independent sources obtained with a linear antenna array and proposes a novel calibration techni...
