Turris undosa</i>; Vera-Peláez <i>et al.</i> (2000): pl. 1, fig. 2 (protoconch), pl. 4, figs 4–6.</p> <p> DESCRIPTION: Shell very variable in proportions and in length of siphonal canal, b/l 0.27–0.32, a/l 0.28–0.42. Suture shallow. Sculptured by sharp spiral cords, with rather wide intervals, bearing fine collabral threads. Subsutural cord low (in fact distinctly impressed), bearing a sharp median ridge with a weak one on either side. Sulcus moderately deep, and recessed under sinus cord, bordered by delicate, oblique scales (instead of a thin lamellate flange as in <i>T. undosa</i>). Sinus cord angular and shouldered (i.e. sloping) towards lip becoming flattened and with two thin ridges. Peripheral cord angular and moderately prominent, separated from sinus cord by a delicate, minute interstitial flange bearing oblique scales. Base of spire whorls with two angular ridges with widely sloping sides, intervals sometimes one or more spiral threads. Base of last whorl with a total of 17–20 spiral ridges, the upper 5–6 the strongest, becoming gradually weaker anteriorly (with a few finer intermediary threads), 5–6 uniformly fine ones on base of rostrum.</p> <p>White or brownish-white, with oblique axial stripes, breaking into spots on base of last whorl, crests of main ridges often with a thin brown line; inner lip and base of last whorl tinged with violet.</p> <p> Protoconch small, conical, <i>ca</i> 2.5 whorls, all except 1st with arcuate axial riblets.</p> <p>Attains 87.5 mm.</p> <p>DISTRIBUTION: Southern Japan and Vietnam to the Philippines, Thailand and Solomon Islands, 10–150 m, sand.</p> <p> TYPES: <i>T. nadaensis</i>: Holotype in private collection of late Masao Azuma, no. 16151, present location not traced.</p> <p> OTHER MATERIAL EXAMINED: JAPAN: Tanabe Bay, Honshu, Japan (ANSP 421607 and 420647).

Springsteen); SOLOMON IS: 9°50.4’S, 160°53.2’E, 82-83m (MNHN)</p> <p> REMARKS: <i>Turris nadaensis</i> is often confused with <i>T. cristata,</i> but is easily distinguished by its weak subsutural cord, much more uniform spirals and non-contracted base. Olivera (2000) discussed variation in <i>T. undosa</i> (as <i>T. nadaensis</i>) and noted the occurrence of a form with a stronger, sharper peripheral cord, rendering the whorls more angular; this form would appear to be typical <i>undata</i>. However, available material of <i>T. nadaensis</i> appears to show variation that is not easy to interpret. Variability in length of siphonal canal and in its degree of tapering is obvious, as is colour of base (vivid violet to pinkish-white). But size also varies: adult Philippine examples are usually 67.0 to 76.0 mm in length, Vietnamese specimens are particularly large (to 87.5 mm) but Thai adults may not exceed 46 mm. One Vietnamese specimen (NMSA L7994) has a particularly short, recurved siphonal canal. Variation in angularity of spiral cords may be visually exaggerated by a distinct spiral line on their crests.</p>Published as part of <i>Kilburn, Richard N., Fedosov, Alexander E. & Olivera, Baldomero M., 2012, Revision of the genus Turris Batsch, 1789 (Gastropoda: Conoidea: Turridae) with the description of six new species, pp. 1-58 in Zootaxa 3244 (1)</i> on pages 37-39, DOI: 10.11646/zootaxa.3244.1.1, <a href="http://zenodo.org/record/246329">http://zenodo.org/record/246329</a>
PERTIDAKSAMAAN AZUMA PADA MARTINGALE UNTUK MENENTUKAN SUPREMUM PELUANG
No full textCounting probability a two-tailed hypothesis determine level of the significance. This case follows positive and negative random variables. So that the probability distribution is a symmetric. The probability will be counted by Azuma inequality on martingales. The lowest upper bound is a decay exponential function. It is determined in some a, n, m, and value by a simulation. The conclusion of this paper is that the random variable value is higher than the probability value (supremum) is lower, vise versa. Therefore, Its property is same as the distribution functio

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Amioidinae Mabuchi & Fraser & Song & Azuma & Nishida 2014, new subfamily
No full textAmioidinae new subfamily Fraser & Mabuchi Type genus Amioides Smith & Radcliffe in Radcliffe 1912 Diagnosis. Incomplete, based on radiographs and external characters: Two dorsal fins VIII or IX dorsal spines deeply divided as VII or VIII+I,9–10; anal fin II,7–8; internal support of spines by serial proximal-middle radials closely associated, 6th and 7th elements broadening at fin division; two supernumerary dorsal spines; three supraneurals; first anal proximal-middle radial straight; 15 branched caudal fin-rays, upper and lower unbranched; preopercle ridge smooth, preopercle edges serrate; large supramaxilla; basisphenoid present; vertebrae10+14; rodlike ribs on 3rd to 10th vertebrae; epineurals present on ribs of 3rd to 8th vertebrae; PU 2 and PU 3 with autogenous haemal spines; two pairs of uroneurals; hypurals 1–5 present, not fused; parhypural free; three epurals; perforated anterior ceratohyal; posttemporal serrate or one or two large spines on edge; cephalic pore system complex with many small pores and canal flutes; multiple pores in lateral-line scales, many free neuromast on lateral-line scales; lateral-line scales large, 24–25, ctenoid; mouth brooding of eggs unknown. Distribution. Amioides is a deep-dwelling (77–267 m) genus known from limited material. The collection sites support the conclusion that it is widespread from continental locations and islands of the Indo-Pacific of East Africa to Japan and Vanuatu (Fraser 2013a). Holapogon is a deeper-dwelling (38–100 m) genus known from limited material from the Andaman Islands and in the Arabian Sea along the west coast of India and Oman. It should be expected along the coast of Yemen and possibly Somalia. Remarks. This subfamily contains two genera, two species: Amioides polyacanthus and Holapogon maximus (Boulenger 1888). Although the latter species was absent from the present molecular analyses, it is placed in this subfamily based on the morphology (see Fraser 1973). Among cardinalfishes the presence of a deeply divided spinous dorsal fin with IX dorsal spines, a visible, but small, eighth dorsal spine, a large supramaxilla shaped lacking an slender antero-proximal point, multiple pores in lateral-line scales with multiple free neuromasts on the lateral-line scales, serrated preopercular edge, perforated anterior ceratohyal, caudal skeleton (three epurals, two pairs of uroneurals, five free hypurals a free parhypural), ribs on 3rd to 10th vertebrae, nine epineurals and vertebrae arrangement with median fins are all plesiomorphic family characters. These characters plus other family characters possessed by this subfamily should be very useful in the hunt for close family relatives. The cephalic arrangement of pores and flutes are likely synapomorphies that united these two large, relatively deep-dwelling genera (Bergman 2004). Other possible synapomorphies await more detailed studies. The osteology of both species has not been studied with cleared and counter stained small specimens. No small specimens, <80 mm SL exist in collections, only large adults up to 198 mm SL (Fraser 2013a).Published as part of Mabuchi, Kohji, Fraser, Thomas H., Song, Hayeun, Azuma, Yoichiro & Nishida, Mutsumi, 2014, Revision of the systematics of the cardinalfishes (Percomorpha: Apogonidae) based on molecular analyses and comparative reevaluation of morphological characters, pp. 151-203 in Zootaxa 3846 (2) on page 175, DOI: 10.11646/zootaxa.3846.2.1, http://zenodo.org/record/492854
