Whose “Fault” Is This? Untangling Domain Concepts in an Ontology of Resilient Computing
No full textCertain ontology domain concepts are difficult to model due to the complexity of their definition, the number of roles that they fulfill or the different types of relationships they participate in. To assist ontologists in overcoming these challenges, a comparative analysis of two Ontology Design Patterns (ODPs) has been carried out. A terminology is introduced that describes the role and certain reusability scenarios of domain concepts in the ODPs studied. These findings make explicit certain potentially implicit modeling decisions previously taken in the ontology modeling field. Our contribution is illustrated with a concrete example from an ontology of resilient computing that will benefit from the outcome of this study

Cryptodacus bernardoi is known only from Colombia in Cundinamarca department in the municipios of Anolaima and Guaduas at middle altitudes on the west side of the eastern cordillera. Host plant. Three of the paratypes were reared from tiny fruits of Phoradendron sp. near piperoides (Kunth) Trel. (Figs. 43, 44), which was found parasitizing the upper part of a Psidium guajava L. shrub. This host plant is locally known by the common names “muérdago”, “matapalo”, “injerto” and “pajarito”. Phoradendron is variously classified in the Santalaceae or Viscaceae. The only previous host data for Cryptodacus was the single record of C. silvai Lima from fruit of “herva de passarinho” (Loranthus sp.) from southern Brazil (Lima 1947). The Loranthaceae, Santalaceae (and Viscaceae, when recognized as distinct from Santalaceae) belong to the order Santalales, many of which are parasitic plants. Etymology. This species is named for José Bernardo Rodríguez, father of the senior author. Comments. This species runs with difficulty in the keys of Norrbom (1994) and Norrbom & Korytkowski (2008). C. bernardoi may be most closely related to C. lopezi Norrbom, which has a similar aculeus, or it may belong to a clade along with that species and C. tau and trinotatus. The abdominal pattern is intermediate between those species, which have a distinct medial brown vitta or pair of vittae bordered by white or yellow sublateral areas on at least tergite 5 and female tergite 6, and the predominantly brown pattern in other species. In C. bernardoi the bands on tergites 4–5 in the male and 5–6 in the female may be interrupted. These four species also have the head mostly or entirely yellow posteriorly. The males were described only for C. bernardoi, C. obliquus, C. parkeri and C. tau.Published as part of Rodriguez, Pedro Alexander, Rodriguez, Erick J., Norrbom, Allen L. & Arévalo, Emilio, 2016, A new species and new records of Cryptodacus (Diptera: Tephritidae) from Colombia, Bolivia and Peru, pp. 276-290 in Zootaxa 4111 (3) on pages 277-279, DOI: 10.11646/zootaxa.4111.3.5, http://zenodo.org/record/26487
A case of the Rodriguez Villegas conjecture
No full textLet L be a number field and let E be any subgroup of the units O_L^* of L. If
rank(E) = 1, Lehmer's conjecture predicts that the height of any non-torsion
element of E is bounded below by an absolute positive constant. If rank(E) =
rank(O_L^*), Zimmert proved a lower bound on the regulator of E which grows
exponentially with [L:Q]. Fernando Rodriguez Villegas made a conjecture in 2002
that "interpolates" between these two extremes of rank. Here we prove a
high-rank case of this conjecture. Namely, it holds if L contains a subfield K
for which [L:K] >> [K:Q] and E contains the kernel of the norm map from O_L^*
to O_K^*

MCN 16.03 / 3038: a dissected specimen from Argatxa cave (Ereñozar karst unit, 15 December 1984). Other material. One dissected specimen from the type locality (15 December 1984), 2 dissected specimens from Goiketxe cave (27 December 2007), 27 specimens (8 dissected, 3 whole-mounted and 16 in 70 % alcohol) from Artzegi cave (18 October 2007, 7 May 2008, 30 July 2008, 17 June 2009, 17 June 2009), 7 specimens (2 dissected and 5 in 70 % alcohol) from Lapurzulo II cave (15 October 2007), 5 dissected specimens from Ubegi II spring (25 October 2007, 25 June 2008), 8 specimens (2 dissected and 6 in 70 % alcohol) from Zubialde spring (18 October 2007) and 3 dissected specimens from Mairulegorreta cave (8 November 1987).

Taxonomic remarks. The lectotype and paralectotype were chosen among the syntypes in the National Museum of Natural Sciences (Madrid). Although the original description by Giani and Rodriguez (1988) was only based on the population of Santa Eufemia-Ereñozar karst unit, new material from Gorbeia karst unit barely modifies the range of values of some characters (Table 1). New measurements of the penial sac and the spermathecal vestibule of the lectotype and paralectotype are given after their re-examination. Main diagnostic characters for the species are: ringed glandular epidermis; comma-shaped atrium with densely granulated epithelial cells in the concave part of the atrium both ental and ectal to the prostate junction, and non granulated epithelial cells in the convex and ectal part (Fig. 3 B); large prostate, joining the atrium subapically by a stout bundle of canals (Fig. 3 B); vas deferens ciliated throughout, longer than atrium, about 20–25 µm diameter, entering the atrium apically; penial sac rounded, maximum diameter 80–110 µm (lectotype: 100 µm; paralectotype: 85 µm); thick cuticular penial sheath, of particular form and size (see measurements of characters in Table 1), with longitudinal folds. One pair of spermathecae containing spermatozeugmata; spermathecal duct narrow (25–35 µm) ending in a spherical vestibule, 75–150 µm maximum diameter (paralectotype: 105 µm). The finding of specimens in different states of development (incompletely mature) in Gorbeia karst unit has revealed details on the formation of the penial sheath. In an early state, the penis is naked and when the formation of the penial sac seems to be completed, a cuticular sheath begins to develop around the penis (d, e, f and h in Fig. 2). In the end, the cuticular sheath covers also the internal wall of the penial sac (a and b in Fig. 2; Fig. 4).Published as part of Achurra, Ainara, Chatelliers, Michel Creuze Des & Rodriguez, Pilar, 2012, Troglodrilus jugeti n. sp.
