No full textBassozetus levistomatus Machida, 1989. 80.5 cm (31.7 in) SL. Circumglobal; western Pacific Ocean north to Izu-Ogasawara Trench (Nakabo in Nakabo 2002); central California (34°40’N, 125°05’W). Depth: 3,965 –5,200 m (13,005 –17,056 ft). All in Nielsen and Merrett (2000).Published as part of Love, Milton S., Bizzarro, Joseph J., Cornthwaite, Maria, Frable, Benjamin W. & Maslenikov, Katherine P., 2021, Checklist of marine and estuarine fishes from the Alaska-Yukon Border, Beaufort Sea, to Cabo San Lucas, Mexico, pp. 1-285 in Zootaxa 5053 (1) on page 81, DOI: 10.11646/zootaxa.5053.1.1, http://zenodo.org/record/557800
Multitestis elongatus Machida 1982
No full textMultitestis elongatus Machida, 1982 (Figs 5–6) New material. Host: Platax pinnatus (Linnaeus), Ephippidae, dusky batfish (Ephippidae). Site: Intestine. Locality: Lizard Island (14°40’S, 145°28’E, April, 2008). Prevalence: 1 of 5. Voucher specimen: QM G 231061. Discussion. Measurements of the single specimen have been included in Table 1. According to Bray et al. (1994), Machida in a personal communication said he considered this species a synonym of Multitestis pyriformis. Having found one specimen that appears to us to be very distinct from M. pyriformis and which generally agrees with Machida’s (1982) description, we believe that Machida was correct originally to describe this form as a new species from Platax orbicularis off Palau. It differs from M. pyriformis in bodyshape (elongate oval vs pyriform; width 29% of body length (new specimen) to 39% (Machida’s data) vs 37– 73% - Machida (1982) fixed his worms under cover glass pressure which may (?) have exaggerated the width somewhat, so the higher figures relating to both species may be result of this fixation technique), sucker width ratio (1:0.97 (new), 0.97–1.00 (original) vs 1:1.01–1.40) and pre-testicular distance (49% (new), 52% (Machida’s data) of body-length vs 30–42%). In addition, the bulk of the cirrus-sac in M. elongatus is oriented antero-posteriorly versus mostly transverse in M. pyriformis.Published as part of Bray, Rodney A., Cribb, Thomas H. & Justine, Jean-Lou, 2010, Multitestis Manter 1931 (Digenea: Lepocreadiidae) in ephippid and chaetodontid fishes (Perciformes) in the south-western Pacific Ocean and the Indian Ocean off Western Australia, pp. 36-46 in Zootaxa 2427 on pages 40-42, DOI: 10.5281/zenodo.29425

Hastatobythites Machida 1997
No full textHastatobythites Machida, 1997 Hastatobythites Machida 1997: 385, type species by original designation Hastatobythites arafurensis Machida, 1997. Hastatobythites: Nielsen et al. 1999: 105. Diagnosis. A monotypic genus of the subfamily Bythitinae (Cohen & Nielsen 1978: 42) with the following characters: two spines placed in midline of head, one anteriorly directed on frontal above eye and another upward directed, weak and thin on ethmoid, three bony ridges on dorsum behind frontal spine; maximum width of head 5.6 –6.0% SL and of body 3.5–3.9 % SL. Also the following combination of characters is diagnostic: Elongate body with joined vertical fins; head naked and anterior part of body with scattered scales in midline and posterior half of body almost fully scaled; skin thin, translucent; eye diameter less than snout-length; opercular spine covered by skin; posterior part of maxilla greatly expanded vertically; dentigerous bones with granular teeth; palatines with 2–3 tooth rows; pectoral peduncle slightly longer than broad, not adnate; gill opening extending well above opercular spine; anterior gill arch with three long rakers; precaudal vertebrae 15 and total vertebrae 57–58; fin rays in dorsal 99–100, caudal 12, anal 64–65 and pectoral 16–17; otolith length to height = 2.5, sulcus undivided, placed in central part of inner face, otolith length to sulcus length = 2.7. Similarity. Hastatobythites is most similar to Saccogaster in having more or less prolonged pectoral radials, naked head, teeth on palatines and thin skin. Hastatobythites differs from Saccogaster by having one median spine on frontal plate (vs. a pair or none), very narrow head (5.6 –6.0 % SL vs. 10.5 –15.0 % SL) and body (3.5–3.9 % SL vs. 4.2–9.5 % SL) and three median bony ridges behind frontal spine (absent or one in Saccogaster). Hastatobythites differs from Parasaccogaster n. gen. in the very narrow head, three median bony ridges behind frontal spine, prolonged free pectoral radials (vs. adnate) and the thin, tight head skin (vs. thick and loose).

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Reflection and transmission in a neutron-spin test of the quantum Zeno effect
No full textThe dynamics of a quantum system undergoing frequent "measurements," leading to the so-called quantum Zeno effect, is examined on the basis of a neutron-spin experiment recently proposed for its demonstration. Unlike in all previous studies, the spatial degrees of freedom of the neutron are duly taken into account. Their inclusion in the analysis is important for two reasons: first, neutron-reflection effects are shown to be very important; second, the evolution may rum out to be totally different from the ideal case. Our results can be interpreted in terms of a rigorous theorem due to Misra and Sudarshan: indeed we clarify that, in contrast with a widespread belief, a quantum Zeno effect does not halt the evolution of a quantum system; it rather modifies it, by forcing the system to remain in a certain subspace, defined by the very measurement performed.

Extension of Fill's perfect rejection sampling algorithm to general chains (Extended Abstract)
No full text. We provide an extension of the perfect sampling algorithm of Fill (1998) to general chains, and describe how use of bounding processes can ease computational burden. Along the way, we unearth a simple connection between the Coupling From The Past (CFTP) algorithm originated by Propp and Wilson (1996) and our extension of Fill's algorithm. 1 Introduction Markov chain Monte Carlo (MCMC) methods have become extremely popular for Bayesian inference problems (consult, e.g., Gelfand and Smith [16], Smith 1991 Mathematics Subject Classification.
