We theoretically demonstrate a method for producing the maximally path-entangled state (1/root2)(\N,0>+exp[iNphi]\0,N>) using intensity-symmetric multiport beam splitters, single photon inputs, and either photon-counting postselection or conditional measurement. The use of postselection enables successful implementation with non-unit efficiency detectors. We also demonstrate how to make the same state more conveniently by replacing one of the single photon inputs by a coherent state.

Electron backscattering diffraction has been applied on polycrystalline diamond films grown using microwave plasma assisted chemical vapour deposition on silicon substrate, in order to provide a map of the individual diamond grains, grain boundary, and the crystal orientation of discrete crystallites. The nucleation rate and orientation are strongly affected by using a voltage bias on the substrate to influence and enhance the nucleation process, the bias enhanced nucleation process. In this work, the diamond surface is mapped using electron backscattering diffraction, then a layer of a few microns is ion milled away exposing a lower layer for analysis and so on. This then permits a three dimensions reconstruction of the film texture.

The purpose of this study was to compare average muscle fiber conduction velocity (CV) and its changes over time in the upper trapezius muscle during a repetitive upper limb task in people with chronic neck pain and in healthy controls. Surface EMG signals were detected bilaterally from the upper trapezius muscle of 19 patients and nine healthy controls using linear adhesive arrays of four electrodes. Subjects were asked to tap their hands in a cyclic manner between targets positioned mid-thigh and 120 degrees of shoulder flexion, to the beat of a metronome set at 88 beats/min for up to 5 min. Muscle fiber CV and instantaneous mean power spectral frequency were estimated for each cycle at the time instant corresponding to 90 degrees of shoulder flexion. Average muscle fiber CV of the upper trapezius muscle was higher in people with chronic neck pain (mean +/- SE, 4.8 +/- 0.1 m/s) than in control subjects (4.4 +/- 0.1 m/s; P
