Oval shaped measuring 1279 – 1610 [1371] long by 939 – 1219 [1010] wide with the holotype 1588 long by 1194 wide. Cephalic margin straight narrowing to an obtuse angle medially; caudal margin becoming slightly concave between the pair of marginal caudal setae (Figs 1, 3, 7)). Margin smooth with slightly roughened and expanded marginal areas at posterior margin of each segment immediately mesad of intersegmental sutures, particularly noticeable in abdominal segments (Figs 3, 9). Dorsum. Longitudinal and transverse sutures on dorsum terminate at margin; pro-mesothoracic suture terminates at margin anteriorly to a position opposite rostrum; mesometathoracic suture terminates at subdorsum. Abdominal rhachis present with lateral arms extending submedially, coalescing with pronounced intersegmental sutures on III–VIII, each rhachis reaching margin (Figs 1, 3–6). Submedian tubercles on dorsum present from cephalothorax extending in a series to abdominal segment VIII (Figs 5, 6). Median width of abdominal segment VII much narrower than preceding segments. Vasiform orifice cordate (Figs 14, 15), operculum (Fig. 15) covering most of orifice and situated 5–6 times the width of the orifice from posterior margin. Lingula (Fig. 13) included within vasiform orifice with head rounded and partially exposed beyond operculum. Chaetotaxy. Cephalothoracic and abdominal setae present on submedian, subdorsal, submarginal and pupal case margin. Two pairs of dorsal submedian cephalic setae and one pair each on T 1, T 2, and T 3 present (Fig. 5). Meso-metathoracic legs with one ventral seta each on basal segment of leg (Fig. 17). Abdominal submedian setae on abdominal A 1, A 3, A 5, and A 7 absent. Pairs of dorsal submedian abdominal setae present on A 2, A 4, A 6, and A 8 (P(n) SmdS where n = 2, 4, 6, 8). Two pairs of P(8)SmdS present with one pair directly anterior and one directly posterior to the vasiform orifice. Also one ventral pair, PVSMdS, of submedian setae (Fig. 14) present lateral to midpoint of vasiform orifice. Margin with more than 20 pairs of evenly distributed setae; submargin with one dorsal abdominal seta paired between each lateral arm of rhachis from A 1 to A 8; subdorsum with two abdominal setae between each lateral arm of rhachis from A 1 to A 7 (one inside and one outside of the ventral fold). (Figs 3, 6). Ve n te r. Legs two segmented, suture between leg segments visible only under high magnification; leg segments angular with their outer lateral angle oriented downward and slightly toward the median, each terminating in adhesive pad (Figs 3, 16, 18); antennae short, overlapping prothoracic leg segment but not extending beyond leg margin (Figs 16, 18). Distinctive ventral margin-concentric fold present slightly distal to legs and at some distance from margin. In vivo, the external margin and the concentric and radiating folds are waxy (Fig. 2). Etymology. The genus is named in honor of the Gadigal tribe, the indigenous inhabitants of the Sydney basin, the area from which the original specimens were collected. Comments. This genus is erected to contain a single unusual new species. It is remarkable for the well-defined segmental sutures including the rhachis, subdorsal papillae, submedian tubercles, two segmented legs, ventral fold, and the setation on the dorsum, venter, margin of the pupal case, subdorsum, and submedian. The unusual ventral fold appears to enclose and protect the legs. The variation in length, diameter, and structure of the dorsal and ventral setae and papillae into different sizes may be the result of effects of host substrates. This species appears to be quite uncommon, and was not found in a repeated search at both collection sites. Gadigaleyrodes froggatti sp. n . Puparium habitus. Thin veneer of clear wax present on dorsum but unapparent in life. Marginal wax not obvious, but whitish wax present ventrally (Fig. 2); puparium found on upper side of leaf; puparium oval shaped, pale brown with two pigmented areas medially, one from mesothoracic to metathoracic segments, and one on abdominal segments V and VI (Fig. 1).

Material examined: Australia, New South Wales: Holotype puparium slide, “Aleurodes sp.”/ “ Syncarpia laurifol ”/ “Bot Gard. Sydney”/ “21.12.[18] 99 ” (apwca091012638002—CASC). Paratypes: 20 puparia on 14 slides same data as holotype, 4 puparia on 3 slides (ASCU), 2 puparia on 1 slide (BMNH), 7 puparia on 5 slides (CASC), 1 puparium slide (CDFA), 4 puparia on 2 slides (PPQC), 1 puparium slide (USNM); 1 puparium slide, Unknown host (climber), Jerusalem Falls, Barrington Tops National Park, NSW, 32.245618o S 151.724361o E, elev 347m, 23 Jan 2008, P.S. Gillespie (ASCT00167723—ASCU) Comments. Despite the slightly damaged label, the handwriting is clearly that of Froggatt (P. Gillespie pers. obs.) and the “Bot Gard. Sydney” he refers to is clearly (the now) Royal Botanic Gardens, in Sydney central district on the shore between the current Sydney harbor bridge and Opera house. Many other specimens similarly labeled are in the collections of ASCU and Froggatt’s interest in these gardens (Froggatt, 1932) showed he liked to collect there. The name of the host, “ Syncarpia laurifol ”, is presumably a misspelling of Syncarpia laurifolia, a junior synonym of Syncarpia glomulifera.Published as part of Dooley Iii, John W. & Gillespie, Peter, 2013, Gadigaleyrodes froggatti, a new genus and species of whitefly (Hemiptera: Aleyrodidae) from Australia, pp. 137-146 in Zootaxa 3608 (2) on pages 138-144, DOI: 10.11646/zootaxa.3608.2.4, http://zenodo.org/record/22421
Arizona Then and Now: Exploring Arizona's Five Cs Through Photography
No full textabstract: Arizona Then and Now: Exploring Arizona's Five Cs Through Photography is a photographic exploration of the evolution of Arizona's five Cs: cotton, copper, citrus, cattle, and climate. This project first looks to the past to see how these five elements shaped the state of Arizona. Photographs were taken across the valley of these elements, or lack thereof, discovering what Arizona has transformed into in the process. Each chapter of the book begins with a brief history of the element focused on in that chapter, followed by an analytical thought about the photographs taken and how the element has evolved. Each chapter shows two historical photographs followed by a series of photographs taken during the project that the author thought depicted what is seen today. The book ends on a final positive note about how the five Cs are not dead, but soon could be completely taken over. This project was a way for a non-art major to explore the state that she grew up while also challenging herself by more than just taking pictures. The photographs displayed in the book depict a sampling of what the author saw that is left of the five Cs
IR-improved DGLAP-CS QCD parton showers in Pythia8
No full textAbstractWe introduce the recently developed IR-improved DGLAP-CS theory into the showers in Pythia8, as this Monte Carlo event generator is in wide use at LHC. We show that, just as it was true in the IR-improved shower Monte Carlo Herwiri, which realizes the IR-improved DGLAP-CS theory in the Herwig6.5 environment, the soft limit in processes such as single heavy gauge boson production is now more physical in the IR-improved DGLAP-CS theory version of Pythia8. This opens the way to one’s getting a comparison between the actual detector simulations for some of the LHC experiments between IR-improved and unimproved showers as Pythia8 is used in detector simulations at LHC whereas Herwig6.5, the environment of the only other IR-improved DGLAP-CS QCD MC in the literature, Herwiri1.031, is not any longer so used. Our achieving the availability of the IR-improved DGLAP-CS Pythia8 then is an important step in the further development of the LHC precision theory program under development by the author and his collaborators

Microporous cesium salts of tetravalent Keggin-type polyoxotungstates Cs-4[SiW12O40], Cs-4[PW11O39(Sn-n-C4H9)], and Cs-4[PW11O39(Sn-OH)] and their adsorption properties
No full textMicroporous cesium salts of modified and unmodified tetravalent Keggin-type polyoxometalates, including Cs-4[SiW12O40], Cs-4[PW11O39(Sn-n-C4H9)], and Cs-4[PW11O39(Sn-OH)], were synthesized. The crystalline structures, which had body-centered cubic (bcc) arrangements, the lattice constants, and the pore-size distributions of the three Cs salts were similar, regardless of the presence or absence and types of functional groups introduced. The Cs salts had only micropores and no mesopores. The micropore size distributions were determined from adsorption isotherms of Ar, which showed a sharp peak at 0.59 nm and a shoulder at 0.62 nm. The fractions of the external surface areas to the total surface areas of the Cs salts were less than 6%. It is plausible that the micropores originate from the heteropoly anion defects in the crystallite, which form to avoid mismatches in the Cs+/(heteropoly anion) ratio required for charge balance (=4) and for a bcc structure (=3). The surface of the Cs salt introduced with n-butyl groups was hydrophobic, although the surface density of the n-butyl groups was low. On the other hand, the hydroxyl groups present on the surface of Cs-4[PW11O39(Sn-OH)] had little effect on the adsorption of water, methanol, ethanol, and hexane but a great impact on that for benzene due to the interactions between the -OH groups and the aromatic rings (-OH center dot center dot center dot pi).

No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
INFRARED SPECTRA OF He--CS, Ne--CS, AND Ar--CS
No full textAuthor Institution: Department of Physics and Astronomy, University of Calgary, Calgary, AB T2N; 1N4, CanadaInfrared spectra of weakly bound Rg--CS (Rg = He, Ne, and Ar) clusters formed in a pulsed supersonic slit-jet expansion have been recorded by exciting the CS fundamental band ( 1535 cm) using a tuneable diode laser. Spectra were well fitted to a conventional semi-rigid asymmetric rotor Hamiltonian. The He--CS spectrum was assigned to an a-type band, while spectra of Ne--CS and Ar--CS were well described by b-type bands, indicating a/b axis switching in transition from the He--CS complex to the Ne--CS and Ar--CS complexes. The results show that the complexes have vibrationally averged T-shaped structures. The determined structural parameters along with the observed vibrational shifts are and {\AA}, and 86.4^irc} and and cm for He--CS, Ne--CS and Ar--CS, respectively.
