A medium-sized brown species, superficially resembling <i>Dasybasis circumdata</i> (Walker), but generally paler, with bare eyes, narrower frons, usually clear indications of ocelli, differently shaped callus; and vein R 4 without appendix. Distinguished from <i>C. palmensis</i> and <i>C. pseudoardens</i> as noted under those species. Readily distinguished from <i>C. bancroftae</i> by its paler brown colouration, absence of brown suffusion on costal cell and wing veins, narrower frons, conspicuous callus extending full width of frons at base, and longer more slender antennae. Length 11–14 mm.</p> <p> <b>Female. Head</b>. Eyes (relaxed) reddish brown, bare, (fine sparse hairs visible at 35X magnification). Frons medium, parallel, index 3.7–4.4, with dark brown tomentum, paler on eye margins, with short dark hairs on darker part; vertex slightly hollow, vertical triangle grey, with relatively dense short hairs; ocellar tubercle well defined, usually with three flat but definite ocelli; callus pyriform, bulging, shiny, brown, nearly full width of frons at base, with tapered extension that reaches to slightly above middle of frons. Subcallus smooth, with greyish white tomentum, yellowish above antennae, without hairs; parafacials and face greyish white, with white hairs mixed with some black ones above and below; beard greyish white. Antennae slender; scape distinctly longer than wide, with well-marked dorsal hood, with greyish tomentum and short black hairs; pedicel cup-shaped, with dorsal prolongation, brown with black hairs; basal plate brown, narrow, with small but sharp sub-basal dorsal angle; style chocolate brown. Palpi thin, tapered to fine point, with relatively long creamy hairs basally above and below, dark brown ones more distally.</p> <p> <b>Thorax.</b> Scutum and scutellum brown with greyish hue, hairs black and creamy white, without well marked tufts or zones. A narrow dark median line and the sublateral ground colour which is darker olivebrown than the median area, give the appearance of two broad, widely separated darker vittae on a relatively pale scutum. Pleura light grey, with greyish white hairs, few darker ones on upper mesopleural convexity.</p> <p> <b>Legs.</b> Femora brown, with greyish overlay, hairs greyish white, anterior surface of fore femora shiny mahogany brown, with black hairs; remaining segments darker brown, darkening to blackish on tarsi, with black hairs.</p> <p> <b>Wings</b>. Uniformly pale greyish; veins brown; stigma inconspicuous relative to previous two species, brown.</p> <p> <b>Abdomen.</b> Cinnamon brown, with dark brown to black hairs. Apical margins well defined, paler brownish grey; tergites 2–5 with median triangles bearing creamy white hairs. Venter brownish grey, darker in centres of sternites, paler on apical edges, hairs black on darker centres, creamy white elsewhere.</p> <p> <b>Male.</b> The male of this species remains in question as none have been collected with characteristic females. However, two specimens are at hand which, although differing somewhat, may be males of <i>C. fergusoni</i>.</p> <p> <b>Mt Waring specimen</b>: Similar to female but with more conspicuous pale median triangles on abdominal tergites and less conspicuous vittae on scutum due to dense covering of erect long dark brown hairs on scutum and scutellum. Eyes bare, (few scattered short hairs just visible at 35X magnification), with upper facets enlarged, reddish brown, contrasting with small darker lower and posterior facets. Ocellar tubercle not observed. Antennae missing. Face greyish white with black hairs. Beard dark brownish black. Palpi with fawn tomentum, with long dark brown hairs. Legs almost uniformly brown, fore tibiae darker brown, with long mixed white and brown hairs on femora, short dark brown hairs elsewhere.</p> <p> <b>Hornsby specimen:</b> A worn and rubbed male specimen differs from the above as follows: ocellar tubercle present, greyish brown, elongate, sunken below level of eyes. Antennal scape and pedicel dark brown with slight dorsal prolongations, with few dark brown hairs; basal plate of flagellum amber-brown, with gentle dorsal angle, style darker brown. Face more grey; palps grey with paler hairs.</p> <p> <b>Distribution.</b> SE QLD from the Brisbane region to the Sydney area NSW and west to the Blue Mountains.</p> <p> <b>Etymology</b>. The specific epithet is in honour of the late Dr E.W. Ferguson, former Director of Public Health in NSW, for his contribution to knowledge of Tabanidae in Australia.</p>Published as part of <i>Mackerras, I. M., Spratt, D. M. & Yeates, D.

DEFRApH - Sample collection and handling procedures
No full textAll chemical and biogeochemical process in the sea are affected by the acidity of the water. Acidity is therefore fundamental property of seawater. The growing concern that the acidity of the oceans might be increasing has revealed weaknesses in our knowledge of this fundamental property and its variation in space and time. In 2008 the DEFRApH project (DEFRA contract ME4133) was initiated to provide this missing information in UK related waters. It required sampling for and analysis of the total inorganic carbon and total alkalinity content of samples. This reports documents the procedures sued for sampling. A companion document Hartman Dumousseaud and Roberts (NOC Internal Document No. 01) describes in detail the analytical procedures used and the calculation of the results
Electron loss and excitation in atom-atom collisions
No full textIn this thesis we consider processes involving collisions of atomic Hydrogen, or a positive ion, with noble gas targets in which the projectile is excited to a discrete state or ionized. Theoretical methods based upon the first Born approximation, the impulse approximation and the pseudostate close-coupling approximation have been used. For sound theoretical reasons it is useful to distinguish between collisions in which the target remains in its ground state, (singly inelastic collisions), from those in which it is excited or ionized (doubly inelastic collisions). Particular attention has been paid to the problem of summing over all final states of the target. One form of the impulse approximation that is used in this thesis requires a knowledge of differential elastic electron-target scattering. To provide this information for noble gas targets a data base of 'best estimates' has been constructed from results published in literature. Also a computer program to calculate elastic electron-noble gas scattering in the static-exchange approximation has been devised. The theoretical basis for this program, which uses the R-matrix method, has been discussed in detail. Applications have been made to the phenomenom of electron loss to the continuum, the theoretical predictions being compared with experimental data for collisions of atomic Hydrogen and positive ions of Carbon, Oxygen and Silicon with gaseous targets of Helium and Argon. Direct excitation of H(1s) to the n = 2 and n = 3 levels in collisions with Helium, Neon, Argon, Krypton and Xenon targets has also been extensively studied.

Sunitinib treatment exacerbates intratumoral heterogeneity in metastatic renal cancer

Stewart) and an educational grant from Pfizer (to T. Powles).Purpose: The aim of this study was to investigate the effect of VEGF targeted therapy (sunitinib) on molecular intratumoral heterogeneity (ITH) in metastatic clear cell renal cancer (mccRCC). Experimental design: Multiple tumor samples (n=187 samples) were taken from the primary renal tumors of mccRCC patients who were sunitinib treated (n=23, SuMR clinical trial) or untreated (n=23, SCOTRRCC study). ITH of pathological grade, DNA (aCGH), mRNA (Illumina Beadarray) and candidate proteins (reverse phase protein array) were evaluated using unsupervised and supervised analyses (driver mutations, hypoxia and stromal related genes). ITH was analysed using intratumoral protein variance distributions and distribution of individual patient aCGH and gene expression clustering. Results: Tumor grade heterogeneity was greater in treated compared to untreated tumors (P=0.002). In unsupervised analysis, sunitinib therapy was not associated with increased ITH in DNA or mRNA. However, there was an increase in ITH for the driver mutation gene signature (DNA and mRNA) as well as increasing variability of protein expression with treatment (p<0.05). Despite this variability, significant chromosomal and transcript changes to key targets of sunitinib, such as VHL, PBRM1 and CAIX, occurred in the treated samples. Conclusions: These findings suggest that sunitinib treatment has significant effects on the expression and ITH of key tumor and treatment specific genes/proteins in mccRCC. The results, based on primary tumor analysis, do not support the hypothesis that resistant clones are selected and predominate following targeted therapy.Peer reviewe

Wavelength tunable 10-GHz 3-ps pulse source using a dispersion decreasing fiber-based nonlinear optical loop mirror
No full textWe experimentally demonstrate the use of a dispersion decreasing fiber (DDF)-based nonlinear optical loop mirror (NOLM) for the generation of wavelength tunable soliton-like pulses at a repetition rate of 10 GHz. We compress ~12 ps Gaussian pulses from an electro-absorption modulator (EAM) (followed by 125 m of DCF for preliminary linear dispersion compensation) into 3 ps pedestal-free pulses using both high-order soliton compression and nonlinear switching effects within an 8.5 km DDF-based loop mirror. The output pulses from the DDF-based NOLM show considerable pedestal reduction compared to those obtained by directly compressing the EAM seed pulses via a single passage through the DDF. Wavelength tuning of the compressed pulses over a ~15 nm bandwidth (from 1541 to 1556 nm) is demonstrated without a significant increase in pulse duration or degradation in pulse quality
