Although the discontinuity structures in the microstrip transmission lines such as a gap and bend have been largely studied, the three-dimensional edge effects, skin effects and metal losses have hardly been analyzed. In this paper, modeling of transmission line with bend and gap discontinuity with equation based process technology independent method are developed. The effect of the signal laye...

The centromere complex is a multicomponent structure essential for faithful chromosome transmission. Here we show that the S. cerevisiae centromere protein Cpf1 bends centromere DNA element I (CDEI) with the bend angle ranging from 66 degrees to 71 degrees. CDEI DNA sequences that carry point mutations which lead to reduced Cpf1 binding affinity and in vivo centromere activity are still able to...

We have designed and fabricated a novel 90 bend in a photonic crystal waveguide. The design was obtained using topology optimization and the fabricated waveguide displays a bend loss for transverse-electric-polarized light of less than 1 dB per bend in a 200-nm wavelength range.

a numerical study has been done through an al2o3–water in a double lid-driven  square  cavity with various  inclination  angles  and discrete heat sources. the top and right moving walls are at low temperature. half of  the  left and bottom walls are  insulated and  the  temperatures of the other half are kept at high. a large number of simulations for a wide  range  of richardson  number  of  ...

JCO/APRIL 2010 © 2010 JCO, Inc. C techniques for activating a closing loop are problematic. Cinching the distal end of the archwire can be time-consuming and inaccurate. Tying back an omega loop between the premolars or between the second premolar and first molar is difficult when the interbracket space is narrow. Lacing back the archwire to a hook is possible, but a crimpable hook can come loo...

In this paper, skew estimation and correction method for document image has been presented. Image of text document can be acquired via camera or other type of machines which cause sometime a skew angle (alignment) on its horizontal direction. To find skew angle of document image, the Radon transform method is used here. The skew angle used in database within the range of ±90o w.r.t x-axis. Kew ...

The coordinated movements of epithelial tissues play vital roles in a variety of processes, from embryonic development to wound healing. The multicellular green alga Volvox carteri is a useful model organism for studying one such movement: epithelial bending [2]. During embryogenesis, the immature spheroid Volvox undergoes a process known as inversion whereby it turns itself completely inside o...

Abstract Employment of protective structures is vital for reducing the effect local scour created surrounding bridge piers. One most effective used controlling and piers collars. Hence, research on mechanism scouring combination pier collar as well reduction great significance. In this study, various width-to-pier width ratios parameters rectangular has been investigated experimentally in 180-d...

The Hawaiian-Emperor bend has played a prominent yet controversial role in deciphering past Pacific plate motions and the tempo of plate motion change. New ages for volcanoes of the central and southern Emperor chain define large changes in volcanic migration rate with little associated change in the chain's trend, which suggests that the bend did not form by slowing of the Hawaiian hot spot. I...
