Taxonomie et écologie des Hymenochaetales dans les forêts de montagne de l'Est de la République démocratique du Congo : le cas du Parc National de Kahuzi-Biega

Hymenochaetales belong to a large group of lignivorous fungi. Forty-one species from 7 genera (Coltricia, Inonotus, Fomitiporia, Fulvifomes, Fuscoporia, Phellinus and Phylloporia) have been recorded in the eastern of DRC for the first time, particularly from the Kahuzi-Biega National Park (KBNP), Virunga National Park (ViNP), in several arboretums as well as in other vegetation types in the region. Inonotus rwenzorianus Balezi & Decock had been recorded as new and Phylloporia afrospathala nom. prov. is added as new. Fulvifomes merrillii, F. grenandensis, F. sublinteus, Phellinus carteri and P. macroporus are recorded for the first time in Africa. In addition, four species are recorded as new to African Great Lakes Region. The ecology of these species had been partially studied, including their relationship with the host plant and their distribution according to plant communities, which distribution depend on the altitude. Habitat, altitude and substrate have an impact on the distribution of the Hymenochaetales in KBNP. Identified species were classified into two trophic groups, either as parasitic on trunk or roots, or saprophytic on dead wood. Following Hymenochaetales distribution, six habitat types had been identified: including primary forest, old secondary forest, young secondary forest, mixed forest of bamboo, glades and arboretum. Five plant communities were favorable to the presence of Hymenochaetales in KBNP. These are: Staudtia stipitata and Julbernardia seretii, Michelsonia microphylla and Monopetalanthus microphyllus, Strombosia scheffleri and Chrysophyllum gorungosanum, Newtonia buchananii and Strombosia scheffleri and finally Ficalhoa laurifolia and Parinari excelsa. Only three species of Hymenochaetales are common for the two main areas (sectors) of KBNP, those species are Fuscoporia gilva, F. senex and F. wahlbergii.

An Aluminum Nitride Integrated Photonics Platform for the Ultraviolet to Visible Spectrum

We demonstrate a wide-bandgap semiconductor photonics platform based on aluminum nitride on sapphire. We measure ring resonators with quality factor >140, 000 at 638 nm and >20, 000 down to 369 nm, which shows a promising path for low-loss integrated photonics in the ultraviolet and visible spectrum.
Seismicity in the vicinity of the Ramapo fault, New Jersey-New York

Abstract Since 1962 the Lamont seismograph network in southeastern New York and northern New Jersey has recorded four small earthquakes with epicenters along the Ramapo fault near the New York-New Jersey border. The northeast trending fault separates the Triassic basin to the southeast from the Precambrian highland to the northwest. The proximity of these events to the fault and the previous earthquake history of the area suggest that much of the seismic activity of the area is associated with this major tectonic feature, which has apparently not been highly active since the Triassic.
${\cal L}_{\infty}$-Norm Computation for Continuous-Time Descriptor Systems Using Structured Matrix Pencils

In this technical note, we discuss an algorithm for the computation of the L∞-norm of transfer functions related to descriptor systems. We show how one can achieve this goal by computing the eigenvalues of certain skew-Hamiltonian/Hamiltonian matrix pencils and analyze arising problems. We also formulate and prove a theoretical result which serves as a basis for testing a transfer function matrix for properness. Finally, we illustrate our results using a descriptor system related to mechanical engineering.
The 2010 ash emissions at the summit craters of Mt Etna: Relationship with seismo‐acoustic signals

Mt Etna volcano (Italy) typically generates lava fountains and Strombolian eruptions from the summit craters, producing significant emissions of tephra which may cause moderate to high impact both in the atmosphere and on the ground. However, we have also witnessed a number of minor ash emissions that, although far less powerful, may pose considerable volcanic hazards. In this paper, we deal with three ash emissions occurring in 2010 (8 April at Southeast Crater, 25 August at Bocca Nuova, and 14–15 November at Northeast Crater), correlating their volcanological features with the associated seismo‐acoustic signals. We provide details regarding the chronology, eruption column, dispersal of the deposit, and texture (grain size, componentry and morphology) of the emitted ash. Each eruptive episode has also been characterized by means of seismo‐acoustic analyses evaluating the volcanic acoustic‐seismic ratio (VASR). Furthermore, the source of volcanic tremor recorded from March to December 2010 was localized. The joint volcanological and seismo‐acoustic analyses allowed distinguishing two main kinds of ash emissions: types a (8 April and 25 August) and b (14–15 November). Regarding the former, the accumulation of gas below a dense cap rock obstructing the conduit vent, giving rise, with the uncorking, to impulsive explosivity, was hypothesized. The latter type instead is characterized by a longer‐lasting and less explosivity, likely due to the existence of open conduit conditions. Therefore, type b ash emissions are less hazardous than type a. This simple model, regarding minor explosive activity, may constitute a starting point to assess the volcanic risk from unexpected explosions.
Creencias sobre la relación familia-escuela. Cambios en el futuro profesorado tras recibir formación específica

espanolLas creencias sobre la relacion familia-escuela de los docentes varian en un continuo segun el papel atribuido a padres y docentes, y el poder que tienen unos y otros. Los futuros docentes tambien tienen creencias sobre esta relacion y su competencia para desarrollarla. En este trabajo participaron dos grupos de futuros docentes, alumnos de segundo curso. Un grupo recibio formacion especifica sobre la relacion familia-escuela y su mejora (116 alumnos del grado de Educacion Infantil, que constituyen el grupo experimental, GE). El otro grupo no recibio dicha formacion (92 alumnos del grado de Educacion Primaria, que constituyen el grupo control, GC). Se elaboro el Cuestionario de creencias sobre las relaciones familia-escuela (CCR) y se aplico antes y despues del entrenamiento del GE. Los resultados indican que los alumnos del GE incrementaron sus creencias sobre la colaboracion familia-escuela en el post-test y redujeron las creencias sobre la subordinacion y dejacion de los padres y sobre la autoridad de los docentes. Los alumnos del GC mantuvieron sus creencias, significativamente mas basadas en la autoridad de los profesores y la subordinacion y dejacion de los padres con respecto al GE. La competencia percibida para relacionarse con las familias no cambio significativamente en ambos grupos. No obstante, se hallaron correlaciones significativas entre las creencias y la competencia percibida, que evidencian la importancia de trabajar con los futuros docentes las creencias basadas en la colaboracion familia-escuela. EnglishTeachers’ beliefs about family-school relationship vary in a continuum according to the role that parents and teachers have, and the power that they hold. Pre-service teachers also have beliefs about this relationship and their own competence to develop it. Two groups of pre-service teachers (second year students) participated in this study. One group received specific training on family-school relationship and its improvement (116 students attending a degree in Early Childhood Education, who constituted the experimental group, EG). The other group was not trained (92 students attending a degree in Primary Education, who made up the control group, CG). The Beliefs about family-school Questionnaire (CCR) was developed and applied before and after the EG was trained. Results show that students in the EG increased their beliefs about family-school collaboration in the post-test and decreased their beliefs about parental subordination to teachers’ authority and parents’ carelessness. Students in the CG kept their beliefs unchanged, which were significantly more prone to support teachers’ authority and parental subordination and parents’ carelessness compared to the EG. Perceived competence for family-school relationship did not change significantly in either group. However, significant correlations between beliefs and perceived competence were found, pointing out the importance of working pre-service teachers’ beliefs about family-school collaboration.
2015 Ieee International Conference on Big Data (big Data) Parallel Meta-blocking: Realizing Scalable Entity Resolution over Large, Heterogeneous Data

—Entity resolution constitutes a crucial task for many applications, but has an inherently quadratic complexity. Typically, it scales to large volumes of data through blocking: similar entities are clustered into blocks so that it suffices to perform comparisons only within each block. Meta-blocking further increases efficiency by cleaning the overlapping blocks from unnecessary comparisons. However, even Meta-blocking can be time-consuming: applying it to blocks with 7.4 million entities and 2.2·10 11 comparisons takes almost 8 days on a modern high-end server. In this paper, we parallelize Meta-blocking based on MapReduce. We propose a simple strategy that explicitly creates the core concept of Meta-blocking, the blocking graph. We then describe an advanced strategy that creates the blocking graph implicitly, reducing the overhead of data exchange. We also introduce a load balancing algorithm that distributes the computationally intensive workload evenly among the available compute nodes. Our experimental analysis verifies the superiority of our advanced strategy and demonstrates an almost linear speedup for all meta-blocking techniques with respect to the number of available nodes. I. Introduction Entity resolution (ER) is the task of mapping different entities to the same real-world object [6]. In the context of Big Web Data, it constitutes a batch process of quadratic complexity that is confronted with two Vs: volume, as it receives a large number of profiles as input, and variety, because the profiles are described by diverse schemata [16], [17] (velocity appears in Incremental ER). Volume is typically addressed by blocking, which places similar profiles into blocks and performs comparisons within each block. Variety is addressed by schema-agnostic blocking methods, which completely disregard attribute names; for instance, Token Blocking [16] creates one block for every token shared by at least two entities. Most of these blocking methods are redundancy-positive, placing profiles into multiple blocks so that the more blocks two profiles share, the more likely they are to be matching [16]. On the flip side, they entail two kinds of unnecessary comparisons: the rendundant ones repeatedly compare the same profiles in multiple blocks, while the superfluous ones involve non-matching profiles. For example, the blocks b 2 and b 4 in Figure 1(a) contain one redundant comparison each, repeated in b 1 and b 3 ; assuming that profiles e 1 and e 2 match with e 3 and e 4 , b 5 , b 6 , b 7
The use of caddisfly fauna (Insecta: Trichoptera) to characterise the Late‐glacial River Trent, England

Trichoptera have been utilised infrequently in palaeoecological studies despite their value as environmental indicators of freshwater habitat structure and quality, via their aquatic larvae, and catchment macroclimate conditions, via the aerial adults. Two sites, dated ca. 11 600 14C yr BP, in the middle reaches of the River Trent (England) supported caddisfly (Trichoptera) assemblages indicative of a dynamic braided river with extensive floodplain development. At the first, Barrow‐upon‐Trent, the caddisfly assemblage was dominated by taxa indicative of a medium to large gravel‐bed river (Lepidostoma hirtum, Micrasema setiferum and taxa from the family Hydropsychidae). At the second site, Hemington, the caddisfly fauna was dominated by taxa from the families Limnephilidae and Phryganeidae. These usually occur in slow flowing and standing waters and are indicative of cut‐off channels on the floodplain. Micrasema setiferum does not occur in the contemporary UK fauna and has a modern distribution across central Europe and Fennoscandia. A gridded climatology extracted for those geographical areas where M. setiferum occurs today indicated a greater degree of continentality than currently prevailing in the Trent catchment. The value of Trichoptera in palaeoecological studies is explored and a model of channel evolution for the River Trent is presented based on caddisfly data. Copyright © 2003 John Wiley & Sons, Ltd.
Ensambles de aves en un sitio quemado y en un sitio no alterado en un área forestal del noroeste de la Patagonia argentina

Se muestrearon las aves de un sitio no alterado y de un sitio afectado por un incendio en un área de la cuenca del arroyo Challhuaco, en el Parque Nacional Nahuel Huapi, Argentina, registrándose la densidad y los sustratos de alimentación de cada especie. Se registraron 24 especies de aves, 19 en el sitio no alterado y 15 en el quemado. Algunas especies presentes en el sitio no alterado no se encontraron o se registraron en menor densidad en el quemado. Estas especies se alimentan sobre el follaje, las ramas y los troncos en pie, o bien habitan sitios húmedos y con alta cobertura. Su ausencia o menor abundancia en el sitio quemado se debería a la reducción de los sustratos de alimentación y a la modificación de la estructura de la vegetación por efectos del fuego. La mayoría de las especies encontradas en el sitio quemado que estuvieron ausentes o presentes en menores densidades en el sitio no alterado comen en el suelo. Su respuesta positiva a la perturbación puede deberse a la mayor disponibilidad de alimento en el suelo quemado y a cambios en la vegetación que les son favorables para sus actividades de alimentación. La diversidad específica fue mayor en el sitio quemado. Esto podría explicarse por el aumento de la heterogeneidad espacial y de la diversidad de los recursos inducidos por el fuego. Algunas especies del sitio quemado podrían moverse a otros ambientes para cubrir sus requerimientos de hábitat.
A diverse shallow-water barnacle assemblage (Cirripedia: Sessilia) from the Oligocene of Southland, New Zealand

An extraordinarily diverse assemblage of cirripedes is described from a shallow-water deposit of late Oligocene age from Cosy Dell farm, near Waimumu, Southland, New Zealand. It is unusual not only because it represents a rarely preserved intertidal to shallow subtidal fauna, but also because it contains at least nine species, five of which are new to science. The deposit contains the earliest known representatives of the genera Chamaesipho and Notobalanus and these are associated with abundant Verruca, an association that no longer occurs in present-day New Zealand waters. Although the remains are intimately associated with each other, the deposit is interpreted as a condensed heterogeneous taphocoenosis, with intertidal zone taxa (Verruca, Chamaesipho, Tetraclitella, Austrobalanus, Protelminius) mixing with upper subtidal species (Eolasma, Notobalanus, Tasmanobalanus) and pelagic cirripedes (Lepas). urn:lsid:zoobank.org:pub:74EECF88-AF4A-4EA7-BF7B-7487D0E35D5D urn:lsid:zoobank.org:act:8D81F5AD-3861-48A5-A54B-CD99621D2525 urn:lsid:zoobank.org:act:D0636517-BEE5-4D10-92A7-1EAD0F54C11A urn:lsid:zoobank.org:act:79A2668E-2CAA-4CE6-AD4E-9035050DBD33 urn:lsid:zoobank.org:act:66B5BDFF-A3F4-4D7C-88E8-6ADB09A25471 urn:lsid:zoobank.org:act:7B508D69-6705-43CA-8C1E-0A98676B604A
Polar stratospheric clouds observed during the Airborne Polar Experiment-Geophysica Aircraft in Antarctica (APE-GAIA) campaign

[1] In this work, observations of polar stratospheric clouds (PSC) carried out during one flight of the stratospheric research aircraft Geophysica deployed in the Airborne Polar Experiment–Geophysica Aircraft in Antarctica (APE-GAIA) campaign in September–October 1999 are presented. An analysis of data from the two lidars and a backscatter sonde on board the Geophysica aircraft is presented, coupled with temperature measurements. The observations are analyzed with the aid of a mesoscale model to provide air mass thermal histories and a microphysical box model to simulate PSC formation. The results obtained from this comparison are discussed in view of the theories for PSC formation processes.
Life at the top of the greenhouse Eocene world--A review of the Eocene flora and vertebrate fauna from Canada's High Arctic

Early–middle Eocene (ca. 53–38 Ma) sediments of the Eureka Sound Group in Canada’s Arctic Archipelago preserve evidence of lush mixed conifer-broadleaf rain forests, inhabited at times by alligators, turtles, and diverse mammals, including primates, tapirs, brontotheres, and hippo-like Coryphodon. This biota reflects a greenhouse world, offering a climatic and ecologic deep time analog of a mild ice-free Arctic that may be our best means to predict what is in store for the future Arctic if current climate change goes unchecked. In our review of the early–middle Eocene Arctic flora and vertebrate fauna, we place the Arctic fossil localities in historic, geographic, and stratigraphic context, and we provide an integrated synthesis and discussion of the paleobiology and paleoecology of these Eocene Arctic forests and their vertebrate inhabitants. The abundance and diversity of tapirs and plagiomenids (both rare elements in midlatitude faunas), and the absence of artiodactyls, early horses, and the hyopsodontid “condylarth” Hyopsodus (well represented at midlatitude localities) are peculiar to the Eocene Arctic. The Eocene Arctic macrofloras reveal a forested landscape analogous to the swamp-cypress and broadleaf floodplain forests of the modern southeastern United States. Multiple climate proxies indicate a mild temperate early–middle Eocene Arctic with winter temperatures at or just above freezing and summer temperatures of 20 °C (or higher), and high precipitation. At times, this high precipitation resulted in freshwater discharge into a nearly enclosed Arctic Ocean basin, sufficient to cause surface freshening of the Arctic Ocean, supporting mats of the floating fern Azolla . Fluctuating Arctic Ocean sea level due to freshwater inputs as well as tectonics produced temporary land bridges, allowing land plants and animals to disperse between North America and both Europe and Asia.
Mapping Seagrass from Space: Addressing the Complexity of Seagrass LAI Mapping

Abstract Information of seagrass LAI is still lacking in most parts of the world due to the high cost of comprehensive mapping. In this paper, we described the use of remote sensing as the cost and time effective solution to perform continuous seagrass LAI mapping, and discussed the issues and difficulties encountered during the mapping. ASTER VNIR and ALOS AVNIR-2 were used to perform the mapping. We proposed at life-form seagrass classification scheme to accommodate the low accuracy of at species level mapping. We also developed sampling mapping unit consist of several factors affecting the distribution of seagrass LAI. The results showed that sensor, method, and environmental limitation contribute to the low accuracy of seagrass LAI mapping.
3D Seismic Surveys for Shallow Targets

Summary A high-resolution 3D seismic survey was undertaken to map shallow stratigraphy near Calgary, Alberta. The survey was 500m x 300m in area, with shot and receiver lines in an orthogonal geometry using 50m line separation. Shots and geophones were spaced at 10m intervals along source and receiver lines, respectively. The surface source used was an 18,000lb EnviroVibe sweeping over a 10Hz to 180Hz range. The survey yielded excellent reflections with a dominant frequency of 50Hz. One high-amplitude west-dipping reflection, occurring between depths of 250m and 450 m, was mapped over the survey area. The project demonstrates the efficacy of reflection seismic surveys for shallow (100m – 500m) targets.
Bayesian modeling of presence-only data

The prediction of species distribution in suitable regions is essential forplanning conservation and management strategies. Unfortunately, quite often the onlyavailable information are the presence of the species at few locations while theassociated environmental covariates can be observed over the complete area of interest.This kind of situation can be seen as a missing data problem with asymmetric andpartial information, we say that data are presence-only data. In this paper we present aBayesian approach to handle with presence-only data, we also consider the case when aspatial effect acts among the observations. MCMC computation has been implementedthrough a data augmentation algorithm allowing us to result consistent estimates for theregression parameters jointly with the unknown species prevalence.
SNIFFI

We present SNIFFI, an innovative gas sensor system for the study and validation of chemiresistive sensing films and artificial smell technique. This system differs from a traditional e-nose, it wants to be an open-source hardware and software platform that can be easily adapted to a wide spread of olfactory scenery. The aim is to open the way to a new typology of gas sensing system that give in output an image “odourmap” representative of odours.
Autonomous Control of Inverter-Interfaced Distributed Generation Units for Harmonic Current Filtering and Resonance Damping in an Islanded Microgrid

Harmonic current filtering and resonance damping have become important concerns in the operation and control of the islanded microgrids. To address these challenges, this paper proposes a control method for the inverter-interfaced distributed generation (DG) units to autonomously share the harmonic currents and resonance damping burdens. The approach employs a load compensator based on the decomposition of output current, in addition to the outer droop-based power controller and the inner voltage and current controllers. The load compensator consists of a virtual-fundamental-impedance loop for the enhanced reactive power sharing and a variable-harmonic-impedance loop which allows to counteract the harmonic voltage drops across the grid-side inductance of the DG inverter and also to dampen out harmonic resonance propagation in the microgrid. Finally, the laboratory tests on a three-phase islanded microgrid setup are carried out to validate the performance of the proposed control scheme.
