Moore, Oct 2010, (1, 92E; 1 NE, mid-body fragment, male with sperm, W: 0.37 mm). Description. (based on holotype and other material where noted). Long, slender body with small parapodia, short, notochaetal paleal fans transparent to pale golden colour. Live Philippine specimen with pale body, bright, lightgold paleae. Holotype 100 segments not entire, length 11 mm, width 0.64 mm. Anterior end same as that described for P.s i l u s n. sp. with two pairs of maroon-red eyes dominating prostomium; median antenna comparatively more subulate, not with swollen tip (Fig. 7 A). Notochaetae of mid-body notopodium composed of 2–4 pointed lateral paleae with slender, fine serrate margins, 4–6 ribs; single sub-unit 1 palea with 7–9 ribs; short spine may be present (Fig. 7 C). Main paleae number up to 10 with shallow apices, serrate convex margin to apex (tiny hoods may be present); 14–17 ribs, nearly all with full length b.l. pattern. Median paleae number 3–5 with (13), 14–17 ribs, including 3−4 noticeable raised ribs and up to 14 b.l. ribs; median broad, leaf-shaped with pointed tips (Fig. 7 B, D). Neurochaetae of mid-body neuropodium composed of 2 superior long falcigers; 1 slightly shorter midsuperior; 15 mid-group falciger; about 5 inferior shortest falcigers. Total number approximately 25 with all compound articles slender; ventral cirrus subulate (Fig. 7 C). Remarks. Paleanotus silopsis n. sp. is represented by two entire specimens from Thailand and Indonesia; other specimens are broken with no anterior or posterior ends present. One GBR individual of 100 segments, not entire, has a length of 11 mm. Diagnostic characters of Paleanotus silopsis n. sp. include broad, leaf shaped and pointed median paleae; broad main paleae rounded distally with a slightly more distinct apex; greater degree of serrated paleae margins and b.l. projection and ventral cirri basally more broad (Figs 1 H; 7 B, D). Paleanotus silopsis n. sp. (western Pacific Ocean) is very similar to P. silus n. sp. (eastern Indian Ocean) but possesses median paleae of a different shape with a greater number of ribs and main paleae with a slightly greater number of ribs (detailed comparison in P. s i l u s n. sp. see Remarks). One male from Raja Ampat had sperm visible in segments 6 to 36 of an entire specimen. A Philippine ovigerous female had large eggs, similar in size to those observed in P. silus n. sp. Segments full of gametes may appear bead-like. A live male from Moorea had a clear body with yellow oil globules inside and white pigment on each segment, indicative of white granules; a condition seen in mature Treptopale species (Watson 2010). Eastern Pacific, Moorea specimen (P. silopsis species complex) exhibits characters similar to the western Pacific P. s i l o ps i s n. sp., but agrees more with Caribbean Sea material collected by the author. These constitute a new species which will be described as part of a genetic study of the ‘ silus / silopsis ’complex (Watson in prep.). Etymology. The species name silopsis refers to this species being very similar in appearance to silus. Silus refers to the pug-nosed shape of the main paleae and the Latin suffix ‘ opsis ’ refers to a likeness. Habitat / Distribution. Paleanotus silopsis n. sp. is present along the western Pacific Ocean rim at Lizard Island, GBR, Indonesia and the Philippines. Found amongst coral rubble from 1− 16 m.Published as part of Watson, Charlotte, 2015, Seven new species of Paleanotus (Annelida: Chrysopetalidae) described from Lizard Island, Great Barrier Reef, and coral reefs of northern Australia and the Indo-Pacific: two cryptic species pairs revealed between western Pacific Ocean and the eastern Indian Ocean, pp. 707-732 in Zootaxa 4019 (1) on pages 724-726, DOI: 10.11646/zootaxa.4019.1.24, http://zenodo.org/record/23424
A microelectrode study of competing electrode reactions in the commercial process for the hydrodimerization of acrylonitrile to adiponitrile
The hydrodimerization of acrylonitrile to adiponitrile is a commercial electrolytic process carried out in a narrow gap, undivided, bipolar cell and with a multiphase electrolyte. As a consequence of the process chemistry, the electrolyte contains oxygen, iron (III), and Pb(II) and the reduction of these species along with hydrogen evolution compete with the reduction of acrylonitrile at the cathode surfaces. This paper defines the cathode reactions which can occur and considers the influence of additives to the electrolyte and of pH changes induced by the cathode reaction itself on the relative importance of the competing electrode reactions

A Simple Modularity Measure for Search Spaces based on Information Theory
Within the context of Artificial Life the question about the role of modularity has turned out to be crucial, especially with regard to the problem of evolvability. In order to be able to observe the development of modular structure, appropriate modularity measures are important. We introduce a continuous measure based on information theory which can characterize the coupling among subsystems in a search problem. In order to illustrate the concepts developed, they are applied to a very simple and intuitive set of combinatorial problems similar to scenarios used in the seminal work by Simon (1969). It is shown that this measure is closely related to the classification of search problems in terms of Separability, Non-Decomposability and Modular Interdependency as introduced in (Watson and Pollack, 2005)
Precision measurement of D meson mass differences
Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected in pp collisions at 7 TeV. Using the decay D 0 → K + K − K − π +, the D 0 mass is measured to be M(D0)=1864.75±0.15(stat)±0.11(syst)MeV/c2.
The mass differences
M(D+)−M(D0)=4.76±0.12(stat)±0.07(syst)MeV/c2,M(Ds)−M(D+)=98.68±0.03(stat)±0.04(syst)MeV/c2
are measured using the D 0 → K + K − π + π − and D+(s)→K+K−π+ mode

Experimental determination of the differential cross section for the reaction d(p,2p)n
A kinematically complete experiment for the reaction d(p,2p)n has been performed for an incident proton energy of 28.61 MeV. Simultaneous detection of the two protons was made by two systems of 96 scintillation detectors each (9216 detector pairs), located uniformly over a 1.22 m diameter spherical scattering chamber. Use of an IBM 7094 computer for on-line data acquisition allowed accumulation of approximately 300,000 three-nucleon break-up events during an eight hour period. The differential cross section as a function of the proton center-of-momentum energies and the total break-up cross section are presented. Comparison of the total break-up cross section with a value suggested by other experiments shows fairly good agreement
