ARGENTINA: Río Negro: Atlantic coast, easternmost kilometer of the colony (41 º 3 ’ S, 62 º 48 ’ W) (Masello & Quillfeldt 2004 b); 3 km west of the mouth of the Río Negro River, 30 km southeast of Viedma (41 º 04’ S, 62 º 50 ’ W) (Masello et al. 2006 a). Further explorations are needed for determining if Cyanolicimex patagonicus is restricted to the type-locality and/or only to the subspecies Cyanoliseus patagonus patagonus. This is the southernmost known limit of the Haematosiphoninae in the Western Hemisphere (Fig. 1), and the third Haematosiphoninae with a Psittacidae bird as a host. Etymology. Specific epithet refers to the Argentinean region where this species was found (Fig. 1). Bionomics of the host and Cyanolicimex patagonicus. The cimicid bugs live inside crevices along the face of the sandstone cliff where the Burrowing Parrots dig their burrows. From there, they access the burrows of the parrots and their breeding chambers. During the first years of bug collection (1999, 2001, 2003, 2004), the numbers of bugs were not quantified, but they were very high around all nests of the study sector at the Burrowing Parrot colony (for details and precise location of the study sector see Masello & Quillfeldt 2002, 2004a). In contrast, the cimicid bug was very scarce in the same parrot colony during December, 2009 (Masello pers. obs.). The summer 2009–2010 was very hot and dry, and the collected specimens died soon after they were extracted from the crevices and burrows. The entire sequence of a breeding season of Cyanoliseus patagonus at El Cóndor (Masello & Quillfeldt 2002, 2004a 2008, Masello et al. 2006) can be, on average, summarized as follows. 1) Return of the migrating birds to the colony: August-September. 2) Copulations: September–October. 3) Incubation of the eggs: October–November. 4) Hatching of the nestlings: end of October through the end of November. 5) Nestling period: end of October through the end of January. 6) Fledgling: end of December through the end of January. 7) Migration (partial): February–March. Therefore, the feeding period of C. patagonicus is restricted when the burrows are occupied by the parrots, i.e., from August −September through the end of January (fledgling of the nestlings). As the breeding pairs spend the night inside the nests during the nestling period (Masello et al. 2006 c), both nestlings and adults can be food sources for C. patagonicus. After this, the bugs are deprived of food for at least 6 months (from February through the end of July). In this way, the bionomics of C. patagonicus are similar to other species of Cimicidae from the nests of swallows in the Northern Hemisphere [Oeciacus vicarius Horvath, 1912 from North America, and Oeciacus hirundinis (Lamark, 1816) from Europe]. Where colonies are reoccupied each year, the three-month breeding period of the cliff swallow Petrochelidon pyrrhonota (Vieillot, 1817) [Aves: Hirundinidae] limits its specialized ectoparasite, O. vicarius, to a short feeding period before host migration, and a food resource deprivation that lasts nine months (Loye 1985). Semi-collapsed and abandoned burrows of C. patagonus are also used by other bird species for nesting. Nevertheless, there are only few records in the literature (Appendix II), probably because of the inaccessibility of the places chosen by the Burrowing Parrots. Observations by one of the authors (J.F.M.) permit the addition of new records (Appendix II). These other bird species may be potential hosts of C. patagonicus, especially if some of them use the burrows for roosting during autumn and winter. Noteworthily, the geographically-distant species Rhynchopsitta pachyrhyncha (Swainson, 1827) [Aves: Psittacidae] from Mexico has a similar-associated ectoparasitic fauna (Table 2). The nests of R. pachyrhyncha are made inside natural cavities or by using old woodpecker holes, forming high-density clusters of nesting pairs sharing nest trees, with a maximum of three nesting pairs per tree. Clusters contained a mean of 11.5 breeding pairs [5 nests/ha]. Thirty-three (68 %) from a total of 48 monitored nest trees were reused for at least 2 nesting seasons; a mean annual reuse was 62 ± 0.08 % nest trees [range 56–71 %] (Monterrubio-Rico et al. 2006). In contrast, Myiopsitta monachus (Boddaert, 1873) [Aves: Psittacidae] is a nonmigratory Psittacidae, that uses its nest year-round for roosting and breeding (Navarro et al. 1992). In this way, the food sources of Psitticimex uritui (Lent & Abalos, 1946) [Hemiptera: Cimicidae] are available all the time. The nests of M. monachus from western and northern Argentina are also colonized by great numbers of Argas monachus Keirans, Radovsky, & Clifford, 1973 [Acari: Argasidae], exclusively specific to this parrot (Turienzo & Di Iorio pers. obs.).

Quantum black holes as classical space factories
No full textSpace and matter may both be manifestations of a single fundamental quantum dynamics, as it may become evident during black-hole evaporation. Inspired by the fact that quantum electrodynamics underlies the classical theory of elasticity, that in turn has a natural and well-known geometric description in terms of curvature and torsion, related to topological defects, here we move some necessary steps to find the map from such fundamental quantum level to the emergent level of classical space and quantum matter. We proceed by adapting the boson transformation method of standard quantum field theory to the quantum gravity fundamental scenario and successfully obtain the emergence of curvature and torsion, our main focus here. In doing so, we have been able to overcome difficult issues of interpretation, related to the Goldstone modes for rotational symmetry. In fact, we have been able to apply the boson transformation method to disclinations, to relate them to the spin structure and to give an heuristic derivation of the matter field equation on curved space. We also improve results of previous work on the emergence of geometric tensors from elasticity theory, as the non-Abelian contributions to the torsion and curvature tensors, postulated in those papers, here emerge naturally. More work is necessary to identify the type of gravity theories one can obtain in this way

Probing a r-nmodification of the Newtonian potential with exoplanets
No full textThe growing availability of increasingly accurate data on transiting exoplanets suggests the possibility of using these systems as possible testbeds for modified models of gravity. In particular, we suggest that the post-Keplerian (pK) dynamical effects from the perturbations of the Newtonian potential falling off as the square or the cube of the distance from the mass of the host star break the degeneracy of the anomalistic, draconitic and sidereal periods. The latter are characteristic temporal intervals in the motion of a binary system, and all coincide in the purely Keplerian case. We work out their analytical expressions in presence of the aforementioned perturbations to yield preliminary insights on the potential of the method proposed for constraining the modified models of gravity considered. A comparison with other results existing in the literature is made
Constraining some r-n extra-potentials in modified gravity models with LAGEOS-type laser-ranged geodetic satellites
No full textWe focus on several models of modified gravity which share the characteristic of leading to perturbations of the Newtonian potential K2 r-2 and K3 r-3. In particular, by using existing long data records of the LAGEOS satellites, tracked on an almost continuous basis with the Satellite Laser Ranging (SLR) technique, we set preliminary constraints on the free parameters K2, K3 in a model-independent, phenomenological way. We obtain |K2|< 2.1× 106 m4 s-2, -2.5× 1012 m5 s-2< K3 < 4.1× 1012 m5 s-2. They are several orders of magnitude tighter than corresponding bounds existing in the literature inferred with different techniques and in other astronomical and astrophysical scenarios. Then, we specialize them to the different parameters characterizing the various models considered. The availability of SLR data records of increasing length and accuracy will allow to further refine and strengthen the present results
The L^P data depth and its application to multivariate process control charts.
No full textControl charts are used to identify non-random behaviours of a manufacturing process by monitoring changes in the distribution of the quality characteristics of the tested product. Process monitoring of related variables is usually referred to as a multivariate quality control problem. In many applications there is not enough information to justify the assumption of a specific form for the underlying process distribution. Thus, a non-parametric approach is a valid tool in a quality control process. Among possible non-parametric statistical techniques, data depth functions are gaining increasing interest in multivariate quality control. The aim of this work is to investigate the behaviour of a non-parametric approach based on the notion of the L^p depth in the statistical process control
