BACKGROUND Timely reporting of influenza A virus subtype affects patient management. Real-time PCR is a rapid and sensitive method routinely used to characterise viral nucleic acid, but the full spectral capability of the instruments is not employed. OBJECTIVES To evaluate a hexaplex real-time PCR assay (Flu-6plx assay) capable of detecting influenza A and B, hMPV, respiratory syncytial virus...

We report measurements of the properties of turbulent thermal convection of a fluid with a Prandtl number Pr = 4.38 in a cylindrical cell with an aspect ratio Γ = 0.50. The rotational symmetry was broken by a small tilt of the sample axis relative to gravity. Measurements of the heat transport (as expressed by the Nusselt number Nu), as well as properties of the large-scale circulation (LSC) ob...

BACKGROUND The relationship between osteopathic manipulative treatment (OMT) and the autonomic nervous system has long been acknowledged, but is poorly understood. In an effort to define this relationship, cervical myofascial release was used as the OMT technique with heart rate variability (HRV) as a surrogate for autonomic activity. This study quantifies that relationship and demonstrates a c...

A high-throughput, broadband optical spectrometer coupled to the Rochester optical streak system equipped with a Photonis P820 streak tube was designed to record time-resolved spectra with 1-ps time resolution. Spectral resolution of 0.8 nm is achieved over a wavelength coverage range of 480 to 580 nm, using a 300-groove/mm diffraction grating in conjunction with a pair of 225-mm-focal-length d...

A dose of 5.0310 antimony (Sb) ions cm was implanted into silicon wafers at an energy of 70 keV, at different tilt angles ~0°, 15°, 30°, 45°, and 60°!. One set of samples was preamorphized with 160 keV germanium (Ge) ions with a dose of 1310 cm. The second set consisted of implants into single crystal silicon. After implantation the samples were annealed at 700 °C for 30 s in a pure nitrogen am...

Two sets of silicon wafers were implanted with 60 keV arsenic ions at a dose of 5x1015 cm-2, using an Applied Materials SWIFT implanter. The first batch consisted of five silicon preamorphised wafers, whilst the second batch was implanted under the same conditions into <100> single crystal wafers. The tilt angle was varied over the range 0o 45o. After implantation the samples were cut into smal...

In this research the polymer which contains aldehyde group [H1] has been prepared by oxidation [H] using oxidizing agent (Dess Martin Periodinane), dialyzed ethanol, Schiff bases[H2,H5andH8] compounds have through reaction of compound with appropriate amines, [H3] hydroquinazolin ring [H2] 2-amino benzoic acid.[H4]which cyclization phthalic anhydride. [H6,H7]were [H5] acid and anhydriede. React...

In mobile communications, post-processing methods are used to improve the intelligibility of speech in adverse background noise conditions. In this study, post-processing based on modelling the Lombard effect is investigated. The study focuses on comparing different spectral envelope estimation methods together with Gaussian mixture modelling in order to change the spectral tilt of speech in a ...

Most cues for Mandarin tone recognition involve pitch, overall intensity and duration. This paper investigates ten other possible cues, and finds one that results in modest, but significant, improvement in classification accuracy on a small speaker-independent corpus of Mandarin news broadcast speech. This cue consists of the energies in the sixteen non-overlapping bands of bandwidth 500Hz from...
