It is shown that manufacturing tolerances of the fiber parameters bend radius and numerical aperture (NA) significantly influence the fiber bend loss performance and spectral response of a fiber based edge filter. A theoretical model, validated by experimental results, is used to determine the changes in key spectral parameters for an edge filter, resulting from changes within their manufacturi...

We develop a Landau theory for bend flexoelectricity in liquid crystals of bent-core molecules. In the nematic phase of the model, the bend flexoelectric coefficient increases as we reduce the temperature toward the nematic to polar phase transition. At this critical point, there is a second-order transition from high-temperature uniform nematic phase to low-temperature nonuniform polar phase c...

We demonstrate a technique for tapering periodically an all-solid soft glass fiber, consisting of two types of lead silicate glasses, by the use of a focused CO(2) laser beam and investigate the bend sensing applications of the periodically tapered soft glass fiber. Such a soft glass fiber with periodic microtapers could be used to develop promising bend sensors with a sensitivity of -27.75 μW/...

We present a novel way to draw planar graphs with good angular resolution. We introduce the polar coordinate representation and describe a family of algorithms for constructing it. The main advantage of the polar representation is that it allows independent control over grid size and bend positions. We first describe a standard (Cartesian) representation algorithm, CRA, which we then modify to ...

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 68-year old male with ischaemic cardiomyopathy who underwent HeartMate II implantation complained of chest discomfort 4 months after the operation. Computed tomography images clearly demonstrated a disconnected outflow graft bend relief (Fig. 1). During reoperation, the bend relief was indeed found to be disconnected and the outflow graft was severely abraded by the sharp metal end of the ben...
