A footnote to a theorem of Kawamata
No full textKawamata has shown that the quasi-Albanese map of a quasi-projective variety
with log-irregularity equal to the dimension and log-Kodaira dimension 0 is
birational. In this note we show that under these hypotheses the quasi-Albanese
map is proper in codimension 1 as conjectured by Iitaka.Comment: Added an addendum by O. Fujino, M. Mendes Lopes, R. Pardini and S.

Antennule with 9+2 aesthetascs, exopod of pleopod 1 elongated, eyes with 24 ommatidia and coxal plate VII with two noduli laterales. Description Maximum length. Male 8.6 mm, female 8.9 mm. Colour. Similar to that of B. trinodulata, except that the unpigmented regions of the pleon are larger on pleonite 1 (figure 32). Cephalothorax. Eyes with 24 ommatidia. Pereion. Tegument smooth and bright. Coxal plate VII has two noduli laterales (figure 49). Co-ordinates b /c and d/c of the noduli laterales (figure 47). Pleon. Narrows abruptly in relation to the pereion; neopleura well-developed on segments 3–5. Pleotelson triangular with straight margins, with a groove on the distal third and rounded apex, reaching halfway down the protopodite of the uropods. Appendages. Antennula tri-articulate, with the distal article having a series of nine aesthetascs at the distal half of the external margin and two apical aesthetascs (figure 33). Antenna when extended posteriorly, reaches the posterior margin of the fourth pereionite. Flagellum and fifth article of the peduncle of sub-equal length. Second flagellar article shorter than the other articles, which have similar lengths; apical organ one-third of the size of the distal article (figure 34). Mandible: similar to that of B. trinodulata, with two penicils on the incisor process and a tuft of at least ten plumose setae. Maxillula: medial endite with two apical penicils, no distal point; lateral endite with 4+6 teeth, five being pectinate (figure 37). Maxilla: external lobe with the distal-lateral margin narrowing; internal lobe covered with fine setae (figure 38). Maxilliped: endite with a long seta and two short teeth on the distal external margin, which has protuberances, dorsally bearing a short and robust seta (as in figure 10); apex of the palp with a tuft of short fine setae (figure 36). Pereiopods: with short tricorns on all articles and a hand-shaped apical seta on the carpus of pereiopod 1 (figure 43). Sexual differentiation: pereiopods 1–4 of the male with the carpus and merus bearing a set of fissured setae; ischium and merus of pereiopod 7 of the male of sub-equal length (figure 44); ischium of the females larger than the merus. Pleopods: exopod of pleopod 1 of the male cordiform, elongated (z: y ratio= 2.3), with a subapical dentiform expansion (figure 39); endopod with small apical spines (figure 40). Exopod of pleopod 2 distally elongated on the internal margin, carrying setae on the external margin; endopod distally tapered (figure 41). Exopod of pleopod 5 with four setae on the external lateral margin (figure 42). Uropod: insertion of the endopod and exopod at the same level; endopod exceeding half the length of the exopod (figure 35). Etymology The name refers to the region where this species occurs, the Brazilian Araucaria Forest. Remarks This species was collected on the Rio-Grandense Plateau (RS), at altitudes above 900 m. Benthana araucariana is similar to B. trinodulata because it has more than one nodulus lateralis on coxal plate VII, is of similar body colour, has similar antenna and uropods, has a similar number of aesthetascs on the antennula (9+2) and in having the insertion of the exopods and endopods of the uropods at similar levels. It can be differentiated by the elongated exopod of pleopod 1 of the male, two noduli laterales on coxal plate VII (three for the other species) and eyes with 24 ommatidia (20 in B. trinodulata).Published as part of Lopes, Paula Beatriz Araujo Elis Regina C., 2003, Three new species of Benthana Budde-Lund (Isopoda, ' Philosciidae') from Brazil, pp. 2425-2439 in Journal of Natural History 37 on pages 2433-243

Cercus with bristles ventrally over full length. Cerci with distal third narrower than middle part in posterior view; diverging. Pregonite with expanded base and sudden narrowing at apex; unicolorous. Postgonite with expanded base, gradually narrowing to apex; unicolorous. Distiphallus with ventroapical concavity with serrated margin, rounded apex, sinuous dorsal outline and ventroapical projections. Vesica symmetrical, with rounded median projection of main branch; distal lobes well developed, with filaments, tapering, partially membranous, with spines on both dorsal and ventral surfaces. Remarks. See under O. bakeri. The female of O. modesta has T7 partially divided into two plates (Tibana & Mello 1985). Distribution. NEOTROPICAL. Brazil (Amapá *, Bahia *, Maranhão, Minas Gerais, Rio de Janeiro, Pará, Pernambuco, São Paulo), Peru. Biology. Under laboratory conditions, O. modesta was reared on agar and powdered milk, developing from first instar to adult in 14–17 days (Lopes 1973b). Adults have been collected from human feces, pig and mouse carcasses, chicken viscera and liver, rotten cow liver, cow lung, fish, sardine, rotten banana mixed with brown sugar, and rotten S. comosa (Lopes 1973b; Linhares 1981; Dias et al. 1984c; Mendes & Linhares 1993; Oliveira et al. 2002; Barbosa et al. 2009; Oliveira & Vasconcelos 2010; Rosa et al. 2011; Vasconcelos et al. 2013; Barbosa et al. 2015; Sousa et al. 2015, 2016; Barbosa et al. 2017). Linhares (1981) observed no differences in attractiveness of human feces, chicken viscera and mouse carcasses for O. modesta. This author also observed a lower occurrence in urban areas as opposed to rural and forest areas, indicating a low degree of anthropophily. Sunlight, as opposed to shaded areas, is also mentioned by Linhares (1981) as a preference of this species. This species was collected from chicken liver and was classified as a necrophagous/omnivorous species by Oliveira & Vasconcelos (2010). Adults have also been collected in a zoological garden in Rio de Janeiro state, Brazil (Oliveira et al. 2002), in the Brazilian Cerrado (Rosa et al. 2011; Sousa et al. 2016), in a coastline region (Barbosa et al. 2015, 2017), and in urban, rural and forest environments (Linhares 1981; Dias et al. 1984c; Mendes & Linhares 1993; Vasconcelos & Araujo 2012; Vasconcelos et al. 2013). In the Brazilian state of Maranhão, O. modesta was classified as accidental and rare (Sousa et al. 2015). It is also considered an early visitor in forensic entomology (Vasconcelos et al. 2013), and showed a strong preference for preserved beaches according to Barbosa et al. (2017).

Radio Emission in Atmospheric Air Showers : Results of LOPES-10
No full textLOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from Extensive Air Showers. Data taken during half a year of operation of 10 LOPES antennas (LOPES-10), triggered by showers observed with KASCADE-Grande have been analyzed. We report about results of correlations found of the measured radio signals by LOPES-10 with shower parameters
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Rowella Lopes & Klautau 2023, GEN. NOV.
No full textGENUS ROWELLA GEN.NOV. Z o o b a n k r e g i s t r a t i o n: h t t p s: / / z o o b a n k.o r g / urn:lsid:zoobank.org:act: 5163DADD-AD0B-47B9- A595-369DACFA329C. Type species: Leucettusa simplicissima Burton, 1932. Synonym: Leucetta – Poléjaeff, 1883: 28; non Haeckel, 1872: 117. Leucettusa – Dendy & Row, 1913: 738; Burton, 1963: 50; Borojević et al., 1990: 258; 2002: 1148; Hooper & Wiedenmayer, 1994: 481; Voigt et al., 2012: 11; Klautau et al., 2013: 454; Riesgo et al., 2018: 835. Etymology: Named after Dr Harold Row for his efforts on the systematics of calcareous sponges and for being the co-author of Leucaltidae. Diagnosis: Leucettidae with an amorphous or tubular massive body.The well-developed cortical skeleton can be comprised of single or multiple layers of triactines and/ or tetractines. The choanosomal and the atrial skeletons are comprised of pygmy triactines and tetractines. Aquiferous system leuconoid, syconoid or both. Remarks: Most of the species here assigned to RoƜella have a tubular body but several others can grow ramifications (e.g. R. simplicissima), while some have a pyriform or amorphous shape (e.g. R. pyriformis and R. dyctiogaster). More than the external morphology, every member of this genus has a peculiar spicule category, named primarily as pygmy triactines and/ or tetractines by Poléjaeff (1883: 67). These spicules are present in the choanosomal and atrial regions, in different proportions among species. We opt to follow Poléjaeff’s termination and refer to these spicules as pygmy in our descriptions. It is important to highlight that Leucaltis and RoƜella were not recovered as sister-taxa. Hence, pygmy spicules are different from the small choanosomal and atrial spicules of Leucaltis, differing from what was previously thought (e.g. Borojević et al., 1990). Pygmy spicules may have even a reduced actine (assuming a V-shape). As Poléjaeff (1883) just called them pygmy, not defining them, we are defining them by their size range (from 10.0–83.0 μm length to 2.5–13.0 μm width) and location scattered in the choanosomal and atrial skeletons. The presence of these morphological traits should be considered in the diagnosis of the genus. We could not resolve doubts on Leucettusa soyo (Hôzawa, 1933). This species had its position questioned in previous works (e.g. Dendy & Row, 1913; Rapp, 2004; Cavalcanti et al., 2013) and was allocated in different calcinean genera. Hôzawa’s (1933) description is doubtful, because important morphological characters, such as the presence of anastomosed tubes, were not clearly mentioned. He described a massive sponge, with radial choanocyte chambers around the atrium. Yet, he also mentioned the presence of ‘ascon-tubes’ and described the aquiferous system as ‘Dendy’s type D’ (Dendy, 1891), i.e. solenoid (Cavalcanti & Klautau, 2011). This is the only description available for this species and it is not satisfactory for its identification. We consider this a case of species inquirenda and highlight Cavalcanti et al. ’s (2013) statement that its position is uncertain and new material is necessary to make a proper genus assignment. Scope: Ten previously described ‘ Leucettusa ’ species are being transferred to the new genus RoƜella: R. connectens (Brøndsted, 1926); R. dictyogaster (Row & Hôzawa, 1931); R. haeckeliana (Poléjaeff, 1883); R. imperfecta (Poléjaeff, 1883); R. lancifera (Dendy, 1924); R. mariae (Brøndsted, 1926); R. pyriformis (Brønsted, 1926); R. simplicissima (Burton, 1932); R. tubulosa (Dendy, 1924) and R. Ʋera (Poléjaeff, 1883). Leucettusa nuda (Azevedo et al., 2009) is considered a junior synonym of R. simplicissima. Leucettusa soyo (Hôzawa, 1933) is considered species inquirenda.Published as part of Lopes, Matheus Vieira & Klautau, Michelle, 2023, Phylogeny and revision of Leucaltis and Leucettusa (Porifera: Calcarea), with new classification proposals and description of a new type of aquiferous system, pp. 691-746 in Zoological Journal of the Linnean Society 198 on pages 715-716, DOI: 10.1093/zoolinnean/zlad008, http://zenodo.org/record/789415
