A Boyer-Moore (or Watson-Watson) type algorithm for regular tree pattern matching
No full textIn this chapter, I outline a new algorithm for regular tree pattern matching. The existence of this algorithm was first mentioned in the statements accompanying my dissertation, [2]. In order to avoid repeating the material in my dissertation, it is assumed that the reader is familiar with Chapters 4 and 5 of the dissertation.

Modeling the Rossiter-McLaughlin Effect: Impact of the Convective Center-to-limb Variations in the Stellar Photosphere
No full textbservations of the Rossiter–McLaughlin (RM) effect provide information on star–planet alignments, which can inform planetary migration and evolution theories. Here, we go beyond the classical RM modeling and explore the impact of a convective blueshift that varies across the stellar disk and non-Gaussian stellar photospheric profiles. We simulated an aligned hot Jupiter with a four-day orbit about a Sun-like star and injected center-to-limb velocity (and profile shape) variations based on radiative 3D magnetohydrodynamic simulations of solar surface convection. The residuals between our modeling and classical RM modeling were dependent on the intrinsic profile width and v sin i; the amplitude of the residuals increased with increasing v sin i and with decreasing intrinsic profile width. For slowly rotating stars the center-to-limb convective variation dominated the residuals (with amplitudes of 10 s of cm s−1 to ~1 m s−1); however, for faster rotating stars the dominant residual signature was due a non-Gaussian intrinsic profile (with amplitudes from 0.5 to 9 m s−1). When the impact factor was 0, neglecting to account for the convective center-to-limb variation led to an uncertainty in the obliquity of ~10°–20°, even though the true v sin i was known. Additionally, neglecting to properly model an asymmetric intrinsic profile had a greater impact for more rapidly rotating stars (e.g., v sin i = 6 km s−1) and caused systematic errors on the order of ~20° in the measured obliquities. Hence, neglecting the impact of stellar surface convection may bias star–planet alignment measurements and consequently theories on planetary migration and evolution

Predictive BRCA1/2 genetic testing: why do men do it?
No full textPurpose: Men who have a family history of breast and/or ovarian cancer may be offered a predictive genetic test to determine whether or not they carry the family specific BRCA1/2 mutation. Male BRCA1/2 carriers may be at increased risk of breast/colon/prostate cancers. Relatively little is known about at-risk men’s decision-making about BRCA1/2 testing. This ongoing qualitative study explores the influences on male patients’ genetic test decisions and the impact of BRCA1/2 predictive genetic testing upon high-risk men and their immediate family.Methodology: Twenty-nine in-depth interviews have been undertaken with both carrier and non-carrier men and immediate family members (17 male patients, 8 female partners 4 adult children), thus far. These explore: their experiences of cancer and genetic testing, decision-making about testing, family support, communication of test results within the family, risk perception and risk managementFindings: The influences on men’s testing decisions, such as, altruism, anxiety about own health and own/partner’s anxiety about children’s risks or curiosity will be examined. Different types of patterns of family communication about DNA-testing and the test results will be described. Some methodological and ethical issues arising during the course of this study will be discussed

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
