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

Halecium tubatum Watson 2008
No full textHalecium tubatum Watson, 2008 (Fig. 5 L) Halecium tubatum Watson, 2008: 174 –175, fig. 10 A, B (in part). Material examined. Holotype, BANZARE, Stn 105, 67° 46 'S 67 °03'E (Mawson Coast), 13 –02– 1931, 163 m; one microslide (Hydr. 710 / 12): F 147470.1, a hydrorhizal stolon giving rise to four stems. Diagnosis. Stems with a single distal hydrotheca, relatively high and strongly widening distally. Rim strongly everted. Gonothecae unknown. Cnidome consisting of at least microbasic mastigophores? Description. All the available material of this species consists of a hydrorhizal stolon giving rise to four stems provided with one or two basal rings (Fig. 5 L). Three stems provided with a single distal hydrotheca; fourth one without hydrotheca. Hydrothecae relatively high and strongly widening distally (Fig. 5 L). Only one hydrotheca with diaphragm. Hydrothecal rim strongly everted (Fig. 5 L). Only a single putative nematocyst could be observed. Measurements (in µm). Hydrothecae: diameter at aperture c. 285, diameter at diaphragm c. 110, height c. 90. Cnidome: microbasic mastigophores? (6 x 2). Remarks. The available material of this species could simply correspond to incipient stems of another haleciid. As indicated above, the hydrotheca in H. tubatum is quite wide, but this could be due to the microslide cover. This is a poorly characterized species, particularly taking into account the absence of gonothecae, the incipient, unbranched stems and the shape of the hydrotheca. In addition, there is practically no information about the cnidome. It should be considered as species inquirenda. As indicated above, part of the material assigned by Watson (2008) to Halecium tubatum actually belong to H. interpolatum (cf. Fig. 5 H–J). It is worth mentioning that, in the material from F 147470.2, the origin of the stem is apparently through a quite long apophysis, in contrast to the basal rings of H. tubatum. In relation to the remaining material assigned by Watson (2008) to H. tubatum, it should be necessary to reexamine it in order to clarify its systematic position. Ecology and distribution. Halecium tubatum was found at depths from 163 to 502 m, off Mawson Coast and Knox Coast (Watson 2008).Published as part of Peña Cantero, Álvaro L., 2014, Revision of the Antarctic species of Halecium Oken, 1815 (Cnidaria, Hydrozoa, Haleciidae), pp. 243-280 in Zootaxa 3790 (2) on pages 274-275, DOI: 10.11646/zootaxa.3790.2.2, http://zenodo.org/record/22689
Energy shifts and relative intensities of K X-rays produced in fast heavy charged particle collisions
No full textCurrent theories of inner-shell ionization in fast ion-atom collisions have been reviews and a simplified classical treatment for multiple inner-shell ionization by Coulomb excitation, based upon the binary encounter model, has been developed. The probability of simultaneous K-plus-L-shell ionization in collisions between Ca, Ti, Fe, and Cu target atoms and fast deuterons, alpha particles, and carbon ions has been investigated. The results show that the fraction of K?? x-rays emitted in the presence of an L-shell vacancy (a) decreases with increasing projectile velocity above a projectile to L-shell electron velocity ration 1, (b) decreases with increasing target atomic number, and (c) increases with projectile charge. The projectile velocity dependence is in fairly good agreement with the simplified classical multiple ionization model. Systematic measurements of the dependence of K??/K?? x-ray intensity rations on target atomic number (19 [less than or equal to] Z [less than or equal to] 47), and on the projectile energy and charge have been carried out. The results were compared with Hartree-Fock-Slater calculations of radiative transition probabilities and found to be consistent with the intensity ratios expected for atoms multiply ionized in the L- and M-shells. Using the information obtained on simultaneous K-plus-L-shell ionization, the energy dependence of the simultaneous M-shell ionization probability was deduced and found to be in good agreement with the simplified classical multiple ionization model. Fission fragments from the spontaneous fission of ???ü???Cf were used to study x-ray spectra for ion-atom collisions involving very heavy projectiles. Spectral measurements of K, Ni, and Br K x-rays and Au L x-rays were carried out and compared with spectra resulting from excitation by alpha particles and photons. The large energy shifts and relative intensity differences observed in the fission fragment excited spectra are similar in character to those observed in fast carbon ion bombardments. Multiple L- and M-shell vacancy configurations together with high ionic charge states are required to reproduce the measured x-ray energy shifts with HFS calculations
A Simple Modularity Measure for Search Spaces based on Information Theory
No full textWithin 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)
