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...

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 Australia, Ross River virus (RRV) is predominantly identified and managed through passive health surveillance. Here, the proactive use of environmental datasets to improve community-scale public health interventions in southeastern Tasmania is explored. Known environmental drivers (temperature, rainfall, tide) of the RRV vector Aedes camptorhynchus are analysed against cumulative case record...

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...

In a no-bend orthogonal drawing of a plane graph, each vertex is drawn as a point and each edge is drawn as a single horizontal or vertical line segment. A planar graph is said to have a no-bend orthogonal drawing if at least one of its plane embeddings has a no-bend orthogonal drawing. Every series-parallel graph is planar. In this paper we give a linear-time algorithm to examine whether a ser...
