    Lawrence, David

    2007-09-14

    The C++ data analysis framework \\emph{JANA} has been written to support the next generation of Nuclear Physics experiments at Jefferson Lab coinciding with the anticipated 12GeV upgrade. The JANA framework was designed to allow multi-threaded event processing with a minimal impact on developers of reconstruction software. This document describes how JANA implements multi-threaded event processing and compares it to simply running multiple instances of a program.

    2007-09-01

    The C++ reconstruction framework JANA has been written to support the next generation of Nuclear Physics experiments at Jefferson Lab in anticipation of the 12GeV upgrade. The JANA framework was designed to allow multi-threaded event processing with a minimal impact on developers of reconstruction software. As we enter the multi-core (and soon many-core) era, thread-enabled code will become essential to utilizing the full processor power available without invoking the logistical overhead of managing many individual processes. Event-based reconstruction lends itself naturally to mutli-threaded processing. Emphasis will be placed on the multi-threading features of the framework. Test results of the scaling of event processing rates with number of threads are presented.

    The C++ reconstruction framework JANA has been written to support the next generation of Nuclear Physics experiments at Jefferson Lab in anticipation of the 12GeV upgrade. This includes the GlueX experiment in the planned 4th experimental hall "Hall-D". The JANA framework was designed to allow multi-threaded event processing with a minimal impact on developers of reconstruction software. As we enter the multi-core era, thread-enabled code will become essential to utilizing the full processor power available without invoking the logistical overhead of managing many individual processes. Event-based reconstruction lends itself naturally to mutli-threaded processing. Emphasis will be placed on the multi-threading features of the framework. Test results of the scaling of event processing rates with number of threads will be shown.

  4. The JANA calibrations and conditions database API

    2010-04-01

    Calibrations and conditions databases can be accessed from within the JANA Event Processing framework through the API defined in its JCalibration base class. The API is designed to support everything from databases, to web services to flat files for the backend. A Web Service backend using the gSOAP toolkit has been implemented which is particularly interesting since it addresses many modern cybersecurity issues including support for SSL. The API allows constants to be retrieved through a single line of C++ code with most of the context, including the transport mechanism, being implied by the run currently being analyzed and the environment relieving developers from implementing such details.

    2012-12-01

    The study on the amphibian fauna of Bukit Jana, Taiping, Perak was carried out from January 2009 until December 2010 with a total of 12 nights of observation. Twenty four species of frogs from 14 genera and 6 families were recorded to inhabit the Bukit Jana areas. Seven commensal species were found around human habitations near the foothill whereas the others are typical forest frogs found mostly near the rivers, streams and forest floor. This is the first amphibian checklist of Bukit Jana, Perak and it contributed 22% out of 107 species of frogs that are recorded to inhabit Peninsular Malaysia.

  7. Phylogeny, Morphology, and Metabolic and Invasive Capabilities of Epicellular Fish Coccidium Goussia janae.

    PubMed

    Dogga, Sunil Kumar; Bartošová-Sojková, Pavla; Lukeš, Julius; Soldati-Favre, Dominique

    2015-12-01

    To fill the knowledge gap on the biology of the fish coccidian Goussia janae, RNA extracted from exogenously sporulated oocysts was sequenced. Analysis by Trinity and Trinotate pipelines showed that 84.6% of assembled transcripts share the highest similarity with Toxoplasma gondii and Neospora caninum. Phylogenetic and interpretive analyses from RNA-seq data provide novel insight into the metabolic capabilities, composition of the invasive machinery and the phylogenetic relationships of this parasite of cold-blooded vertebrates with other coccidians. This allows re-evaluation of the phylogenetic position of G. janae and sheds light on the emergence of the highly successful obligatory intracellularity of apicomplexan parasites. G. janae possesses a partial glideosome and along with it, the metabolic capabilities and adaptions of G. janae might provide cues as to how apicomplexans adjusted to extra- or intra-cytoplasmic niches and also to become obligate intracellular parasites. Unlike the similarly localized epicellular Cryptosporidium spp., G. janae lacks the feeder organelle necessary for directly scavenging nutrients from the host. Transcriptome analysis indicates that G. janae possesses metabolic capabilities comparable to T. gondii. Additionally, this enteric coccidium might also access host cell nutrients given the presence of a recently identified gene encoding the molecular sieve at the parasitophorous vacuole membrane.

  10. Prevalence of STDs among prostitutes in Czech border areas with Germany in 1997–2001 assessed in project "Jana"

    PubMed Central

    Resl, V; Kumpova, M; Cerna, L; Novak, M; Pazdiora, P

    2003-01-01

    Objectives: To prevent STDs, including HIV/AIDS, and assessment of STD prevalence in the target group. Methods: Prostitutes working in night clubs and in the streets and roads of three districts in the West Bohemian Region of the Czech Republic bordering on Germany were studied. Interactions included street work, venereology check up, psychology and sociology counselling, psychological preparation on possible treatment, and continuous and regular contact. Results: The number of "love clubs" involved in project "Jana" increased from 46 in 1997 to 72 in 2000. Of 561 street girls registered in the project during 1997–2001, there was one HIV positive, every 11th prostitute had syphilis, and one in 93 women had gonorrhoea, whereas incidence of syphilis in the Czech Republic was 10.2/100 000 and that of gonorrhoea 9.5/100 000 inhabitants in 2001, 31 women had Chlamydia trachomatis urinary tract and genital infection, and 25 were HBsAg positives. STD frequency revealed in project participants significantly exceeds numbers of STDs in the other inhabitants of the Czech Republic. The majority of prostitutes were foreigners, mostly Ukrainians and Russians. Conclusion: The situation in the border areas is alarming. The priority must be to concentrate efforts on prevention of spread of venereal diseases in borders of economically disparate states. PMID:14663136

    Černá, Alena M.; Hadrava, Petr; Hadravová, Alena; Stluka, Martin

    The critical edition of the collection "King John's Astronomy" is based on the Old Czech manuscript written at the beginning of the 15th century which is preserved at the Library of the National Museum in Prague (ms. II F 14). The collection consists of several separate parts - first of all it contains astronomical and astrological treatises refering to Ptolemy's works. Explanations on the impact of the seven planets and twelve zodiacal signs on the fate of man, who was born under their influence, prevail in the texts. The texts which are connected with Hippocrates and Galenos' doctrines about humoral physiology and humoral pathology are another subject. They are supplemented by a treatise on blood-letting and by pharmaceutical instructions on different weight units. Another treatise deals with God, God's acts and with human fate. The manuscript also contains calendar tools for the calculation of Easter and other feasts during the year. The origin of this Old Czech text coincides with the period of the development of national languages as languages of science. Vocabulary contained in the manuscript is rich. It yields evidence about the formation of terminological systems in various fields involved in the collection. The Old Czech language of this literary monument exhibits unexpectedly archaic features. The present edition is a result of interdisciplinary collaboration of researchers from the fields of diachronic Bohemistics, classical philology, and astronomy. The publication is completed with the critical apparatus, indices, vocabulary, by a list of the chosen literature and other related supplements.

    A chub of previously ambiguous identity from the Boljunscica and Pazincica rivers (south-eastern Istra Peninsula) was studied and compared with geographically close Squalius squalus, Squalius zrmanja, and Squalius janae recently described from the Dragonja River drainage in the Adriatic Sea basin in Slovenia. It was shown that the chub from the south-eastern Istra Peninsula differs from all know species of Squalius but one: Squalius janae. Three samples examined from Boljunscica and Pazincica rivers and Squalius janae from its type locality, Dragonja River, show the following characters typical for the latter species: a long head (the head length 27-32% SL); a pointed conical snout with a clearly projecting upper jaw; a long straight mouth cleft, the lower jaw length (39-45% HL) exceeding the caudal peduncle depth; a large eye; commonly 9? branched anal-fin rays; commonly 44 total vertebrae (24+20 or 25+19); bright silvery colouration, scales easily lost; iris, pectoral, pelvic and anal fin pigmentation with yellow shades. The data on the distribution of Squalius chubs in the northern Adriatic basin support the assumption that the range of Squalius janae is determined by the geology of the Trieste Flysch Basin and the Pazin Flysch Basin forming the base of the Istra Peninsula. The distribution pattern of this species does not support a simple model of fish dispersal and a complete connectivity within the whole Palaeo-Po historical drainage. Indeed, it indicates a disrupted surface palaeohydrography that was heavily fragmented by karstification in the whole Dinaric area.

    Biological oceanographer Jana Davis is AGU's Congressional Science Fellow for 2004-2005. She will spend the year in the office of U. S. Senator Frank Lautenberg (D-N. J.), working on ocean and other environment issues. Davis received her Ph.D. in 2000 from the Scripps Institution of Oceanography in San Diego, California, and most recently was with the Maritime Studies Program, Williams College-Mystic Seaport in Connecticut, and the Smithsonian Environmental Research Center in Maryland. She is AGU's 28th Congressional Science Fellow. Davis applied for the fellowship in order to focus on policy at this point in her career. She observed, ``I feel that cases in which policy might benefit from increased incorporation of science outnumber those in which science lags policy.'' Davis said that the fellowship will ``provide the ideal educational experience'' to learn how policy makers struggle to ``balance current human need with future human and ecological value.''

    Although the occurrence of Pleistocene mammals is abundant in many localities of Minas Gerais State (e.g., Lagoa Santa, Janaúba, Bambuí, Cordisburgo, Patos de Minas, Araxá), there are no references at present of Quaternary megafauna in Uberaba, Triângulo Mineiro, southeastern Brazil. This region is traditionally recognized for its taxonomically diverse fauna of the Late Cretaceous Bauru Group. In 2006, fossil material attributed to giant ground sloth Eremotherium laurillardi (Xenarthra, Megatheriidae), a typical taxon of the Brazilian Pleistocene, was discovered in the Uberaba City (Minas Gerais State). The specimen (CPP 1122) which is here described consists of several cranial and postcranial bones of a single individual. The material was confined to a small alluvial deposit, yielding in the Córrego da Saudade stream, which due its restricted area distribution it is not represented in geological maps.

    The distinctive pattern of element concentrations in the upper mantle provides essential evidence in our attempts to understand the accretion and differentiation of the Earth (e.g., Drake and Righter, 2002; Jones and Drake, 1986; Righter et al., 1997; Wanke 1981). Core formation is best investigated through use of metal/silicate partition coefficients for siderophile elements. The variables influencing partition coefficients are temperature, pressure, the major element compositions of the silicate and metal phases, and oxygen fugacity. Examples of studies investigating the effects of these variables on partitioning behavior are: composition of the metal phase by Capobianco et al. (1999) and Righter et al. (1997); silicate melt composition by Watson (1976), Walter and Thibault (1995), Hillgren et al. (1996), Jana and Walker (1997), and Jaeger and Drake (2000); and oxygen fugacity by Capobianco et al. (1999), and Walter and Thibault (1995). Here we address the relative influences of silicate melt composition, pressure and temperature.

    In attempt to induce doubled haploids in potato we studied interspecific hybrids between tetraploid Solanum tuberosum cultivars Igor, Jana, Vesna, Romano, Arinda, Fianna, Donald and Vital and Solanum phureja (clone IVP 48). Four out of eight cultivars produced 21 berries in total and 149 seedlings were obtained. Their ploidy was measured using flow cytometry. Analysis revealed 137 tetraploids, 10 triploids and 2 haploids. One haploid, 6 triploids and most of the tetraploids produced tubers. Nine out of 10 triploids were produced in a cross between cv. Igor and S. phureja. The vigour of the haploid plant was weak and produced characteristic long light yellow tubers. Triploid plants were characterized by a dark violet coloration of the stem, which was the same as the coloration of the S. phureja. Tubers had violet skin colour of various intensities and deep eyes. The majority of the tetraploid plants (135) were phenotypically similar to the S. tuberosum, while two plants had a similar violet stem and tubers as the triploids. Triploids were interspecific hybrids and tetraploids were produced by spontaneous chromosome doubling from S. tuberosum gametes. Two tetraploid plants expressing violet coloration might have been interspecific hybrids formed from 2n S. phureja gametes. Further studies are needed to confirm these assumptions.

    The iron gall inks were one of the writing materials mostly applied in historical documents of the western civilization. Due to the ink corrosive character, the documents are faced with a danger of being seriously, and in some cases also irreversibly changed. The elemental composition of the inks is an important information for taking the adequate conservation action [Project InkCor, http://www.infosrvr.nuk.uni-lj.si/jana/Inkcor/index.htm, and references within]. Here, the in-air PIXE analysis offers an indispensable tool due to its sensitivity and almost non-destructive character. An experimental approach developed for precise and automatic analysis of documents at Jožef Stefan Institute Tandetron accelerator is presented. The selected documents were mounted, one at the time, on the positioning board and the chosen ink spots on the sample were irradiated by 1.7 MeV protons. The data acquisition on the selected ink spots is done automatically throughout the measuring pattern determined prior to the measurement. The chemical elements identified in the documents ranged from Si to Pb, and between them the significant iron gall ink components like Fe, S, K, Cu, Zn, Co, Mn, Ni were deduced with precision of ±10%. The measurements were done non-destructively and no visible damage was observed on the irradiated documents.

    Professor Bolesław Jałowy (1906-1943) was a chairman of Department of Histology and Embryology at Faculty of Medicine of King John Casimir University (Polish: Universytet Jana Kazimierza: UJK) in Lvov. He succeeded Professor Władysław Szymonowicz (1869-1939) who held this position for decades. As the most skillful followers of his tutor, Bolesław Jałowy was a great investigator of physiology of human tissue, embryogenesis, histological consequences of female sex hormones on blood clotting action as well as regeneration of nerves in addition to description of silver staining technique for reticulin fibers of skin. He was a hard working person with gentle attitude to such a subtle matter as microscopic structure of human body. However, he happened to live in brutal conditions of nationalistic struggles. His example shows how much a dedicated scientist could do in a very short time as his life was tragically ended with murdering him during World War Two. His story is a great lesson for generations of academic workers how to meet high moral standards with efficient and creative scientific work in evil and destructive, nationalistic climate that occurs usually in wartime.

    The determination of crop evapotranspiration (ETc) values is very useful information for planning irrigation, water supply estimation, regulation of water rights and river basins hydrologic studies. Values of ETc in the North region of Minas Gerais state, Brazil, were estimated in this research from the multispectral images of the Landsat 5 TM by means of the model Surface Energy Balance Algorithm for Land- SEBAL, based on the simplified energy balance equation of a surface covered by vegetation, using a few daily surface climatological parameters (wind speed, rainfall, air temperature and relative humidity, solar radiation). The aim of this study was to estimate the regional spatial distribution of the energy balance components and evapotranspiration in the study area, covering the irrigated perimeter of Gorutuba, involving the cities of Nova Porteirinha, Janaúba, Porteirinha, Verdelândia and Pai Pedro. Thematic maps of regional evapotranspiration and energy balance components were generated from spectral analyzes of the images obtained, associated with the used weather data. The ability of SEBAL to provide the spatial variability of energy balance components, including evapotranspiration, demonstrated its sensitivity to different occupation of the soil surface vegetation, and to high data temporal and spatial resolutions data, indicating that the SEBAL model can be used in scales and operational routine for north region of Minas Gerais.

    Accurate structure refinement from electron-diffraction data is not possible without taking the dynamical-diffraction effects into account. A complete three-dimensional model of the structure can be obtained only from a sufficiently complete three-dimensional data set. In this work a method is presented for crystal structure refinement from the data obtained by electron diffraction tomography, possibly combined with precession electron diffraction. The principle of the method is identical to that used in X-ray crystallography: data are collected in a series of small tilt steps around a rotation axis, then intensities are integrated and the structure is optimized by least-squares refinement against the integrated intensities. In the dynamical theory of diffraction, the reflection intensities exhibit a complicated relationship to the orientation and thickness of the crystal as well as to structure factors of other reflections. This complication requires the introduction of several special parameters in the procedure. The method was implemented in the freely available crystallographic computing system Jana2006.

  15. Incommensurate lattice modulations in Potassium Vanadate

    NASA Astrophysics Data System (ADS)

    Potassium Vanadate (K2V3O8) is an S = 1/2 2D square lattice antiferromagnet that shows spin reorientation indicating a strong coupling between the magnetism and its dielectric properties with a promise of rich physics that promises multiferroicity. These tangible physical properties are strongly tied through a spin-lattice coupling to the underlying lattice and superlattice behavior. It has a superlattice (SL) onsetting below Tc = 115 K with an approximate [3 x 3 x 2] modulation. Here we present our recent experiments at TOPAZ beamline at SNS which for the first time proves conclusively that the lattice modulations are incommensurate, with an in-plane Q of 0.315. We will also show our attempts to refine the data using JANA which requires a redefinition of the lattice, as well as the temperature and Q dependence of the superlattice modulation measured using neutrons at HFIR and synchrotron x-rays at APS. Our results are not only relevant for the ongoing search of multifunctional behavior in K2V3O8 but also generally for the superlattice modulations observed in a large family of fresnoites. Work performed at ORNL and ANL is supported by U.S. Dept. of Energy, Office of Basic Energy Sciences and Office of User Facilities Division.

  16. Effect of alteration in the global body plan on the deployment of morphogenesis-related protein epitopes labeled by the monoclonal antibody 12G9 in Tetrahymena thermophila.

    2003-04-01

    We have employed monoclonal antibodies to reinvestigate the janus mutants of the ciliate Tetrahymena thermophila, which cause reversal of circumferential polarity on the dorsal surface of the cell. This reversal brings about frequent ectopic expression of ventral cortical landmarks, such as a "secondary" oral apparatus, on the dorsal surface. The principal antibody employed, FXXXIX-12G9, immunolabels both transient cortical structures not directly associated with basal bodies (the fission line and the postoral meridional filament) and more permanent structures (apical band and oral crescent) that are associated with basal bodies. 12G9-immunolabeling of janus cells has revealed additional phenotypes, including disorder of ciliary rows. Further, this labeling has shown that the postoral meridional filament is often expressed and the apical band is frequently interrupted on the mid-dorsal surface of janus cells irrespective of whether or not these cells express a "secondary" oral apparatus. Of the permanent structures revealed by 12G9 immunofluorescence, modifications of the oral crescent (OC) are associated with prior modifications in the development of basal body-containing structures in the secondary oral apparatus. The formation of the apical band (AB) is also commonly abnormal in janus cells; analysis of specific abnormalities shows that the AB depends both on its initiation at a specific site near the anterior basal body of apical basal body couplets and on the normal location of these couplets just posterior to the fission line. We also have uncovered an intriguing difference in the reactivity of apical-band filaments to the 12G9 antibody in the two non-allelic janus mutants (janA1 and janC2) that we have investigated. Taken together, our observations indicate that the formation of new cellular structures at division depends both upon pre-existing cytoskeletal structures and upon the positional information provided by large-scale cellular polarities.

  17. Alkalinity Enrichment Enhances Net Calcification of a Coral Reef Flat

    NASA Astrophysics Data System (ADS)

    Albright, R.; Caldeira, K.

    2015-12-01

    Ocean acidification is projected to shift reefs from a state of net accretion to one of net dissolution sometime this century. While retrospective studies show large-scale changes in coral calcification over the last several decades, it is not possible to unequivocally link these results to ocean acidification due to confounding factors of temperature and other environmental parameters. Here, we quantified the calcification response of a coral reef flat to alkalinity enrichment to test whether reef calcification increases when ocean chemistry is restored to near pre-industrial conditions. We used sodium hydroxide (NaOH) to increase the total alkalinity of seawater flowing over a reef flat, with the aim of increasing carbonate ion concentrations [CO32-] and the aragonite saturation state (Ωarag) to values that would have been attained under pre-industrial atmospheric pCO2 levels. We developed a dual tracer regression method to estimate alkalinity uptake (i.e., calcification) in response to alkalinity enrichment. This approach uses the change in ratios between a non-conservative tracer (alkalinity) and a conservative tracer (a non-reactive dye, Rhodamine WT) to assess the fraction of added alkalinity that is taken up by the reef as a result of an induced increase in calcification rate. Using this method, we estimate that an average of 17.3% ± 2.3% of the added alkalinity was taken up by the reef community. In providing results from the first seawater chemistry manipulation experiment performed on a natural coral reef community (without artificial confinement), we demonstrate that, upon increase of [CO32-] and Ωarag to near pre-industrial values, reef calcification increases. Thus, we conclude that, the impacts of ocean acidification are already being felt by coral reefs. This work is the culmination of years of work in the Caldeira lab at the Carnegie Institution for Science, involving many people including Jack Silverman, Kenny Schneider, and Jana Maclaren.

    We perform histogram-reweighting grand canonical Monte Carlo simulations of the Lennard-Jones fluid confined between two parallel hard walls and determine the vapor-liquid critical and coexistence properties in the range of σ ≤H≤6σ and 10σ≤Lx,Ly≤28σ, where H is the wall separation, Lx=Ly is the system size and σ is the characteristic length. By matching the probability distribution of the ordering operator, P(M ), to the three-dimensional (3D) and two-dimensional (2D) Ising universality classes according to the mixed-field finite-size scaling approach, we establish a "phase diagram" in the (H,L) plane, showing the boundary between four types of behavior: 3D, quasi-3D, quasi-2D, and 2D. In order to facilitate 2D critical point calculation, we present a four-parameter analytical expression for the 2D Ising universal distribution. We show that the infinite-system-size critical points obtained by extrapolation from the apparent 3D and 2D critical points have only minor differences with each other. In agreement with recent reports in the literature [Jana et al., J. Chem. Phys. 130, 214707 (2009)], we find departure from linearity in the relationship between critical temperature and inverse wall separation, as well as nonmonotonic dependence of the critical density and the liquid density at coexistence upon wall separation. Additional studies of the ST2 model of water show similar behavior, which suggests that these are quite general properties of confined fluids.

  20. Electron emission in collisions of fast highly charged bare ions with helium atoms

    2016-01-01

    We have studied the electron emission from ground state helium atom in collision with fast bare heavy ions at intermediate and high incident energies. In the present study, we have applied the present three-body formalism of the three Coulomb wave (3C-3B) model and the previously adopted four-body formalism of the three Coulomb wave (3C-4B). To represent the active electron in the helium atom in the 3C-3B model, the initial bound state wavefunction is chosen to be hydrogenic with an effective nuclear charge. The wavefunction for the ejected electron in the exit channel has been approximated to be a Coulomb continuum wavefunction with same effective nuclear charge. Effectively the continuum-continuum correlation effect has been considered in the present investigation. Here we have calculated the energy and angular distribution of double differential cross sections (DDCS) at low and high energy electron emission from helium atom. The large forward-backward asymmetry is observed in the angular distribution which is explained in terms of the two-center effect (TCE). Our theoretical results are compared with available experimental results as well as other theoretical calculations based on the plain wave Born approximation (PWBA), continuum-distorted wave (CDW) approximation, continuum-distorted wave eikonal-initial state (CDW-EIS) approximation, and the corresponding values obtained from the 3C-4B model [S. Jana, R. Samanta, M. Purkait, Phys. Scr. 88, 055301 (2013)] respectively. It is observed that the four-body version of the present investigation produces results which are in better agreement with experimental observations for all cases.

  2. Effect of water on metal-silicate partitioning and hydrogen incorporation in the core of the Earth and Mars

    The accretion of planets from primordial materials and their subsequent differentiation to form a core and a mantle are fundamental questions in terrestrial and solar system. Many of the questions about the processes are still open and much debated. For example, could the presence of water during the metallic phase segregation affect the planet-accretion models? The existing studies on the elemental metal-silicate partitioning under hydrous conditions are limited to 1 GPa [5,6] well below the likely conditions prevailing during core formation on Earth and Mars. In the present study we use multi-anvil technique aver a range of P, T, fO_2 and water content (5 - 20 GPa, 2000 - 2500 K, from 1 to 5 log units below the iron-wüstite buffer, and for XH2O varying from 500 ppm to 1.5 wt.{%}). The present experimental results show that except for Fe, there is no effect of water on the partitioning of moderately siderophile elements. It allowed us to build consistent models of planetary accretion from reducing to oxidized conditions. Furthermore, for the range of water concentrations studied, there is no evidence of an important hydrogen incorporation into planetary cores, thus making unlikely for hydrogen to be a major light element of the core as previsously assumed [7].

    The 6th edition of the Workshop for Young Scientists on the Physics of Ultrarelativistic Nucleus-Nucleus Collisions (Hot Quarks 2014) was held in Las Negras, Spain from 21-28 September 2014. Following the traditions of the conference, this meeting gathered more than 70 participants in the first years of their scientific careers. The present issue contains the proceedings of this workshop. As in the past, the Hot Quarks workshop offered a unique atmosphere for a lively discussion and interpretation of the current measurements from high energy nuclear collisions. Recent results and upgrades at CERN's Large Hadron Collider (LHC) and Brookhaven's Relativistic Heavy Ion Collider (RHIC) were presented. Recent theoretical developments were also extensively discussed as well as the perspectives for future facilities such as the Facility for Antiproton and Ion Research (FAIR) at Darmstadt and the Electron-Ion Collider at Brookhaven. The conference's goal to provide a platform for young researchers to learn and foster their interactions was successfully met.

    Observations of land-atmosphere interactions using satellite data Julia Green (1), Pierre Gentine (1), Alexandra Konings (1,2), Seyed Hamed Alemohammad (3), Jana Kolassa (4) (1) Columbia University, Earth and Environmental Engineering, NY, NY, USA, (2) Stanford University, Environmental Earth System Science, Stanford, CA, USA, (3) Massachusetts Institute of Technology, Civil and Environmental Engineering, Cambridge, MA, USA, (4) National Aeronautics and Space Administration/Goddard Space Flight Center, Greenbelt, MD, USA. Previous studies of global land-atmosphere hotspots have often relied solely on data from global models with the consequence that they are sensitive to model error. On the other hand, by only analyzing observations, it can be difficult to distinguish causality from mere correlation. In this study, we present a general framework for investigating land-atmosphere interactions using Granger Causality analysis applied to remote sensing data. Based on the near linear relationship between chlorophyll sun induced fluorescence (SIF) and photosynthesis (and thus its relationship with transpiration), we use the GOME-2 fluorescence direct measurements to quantify the surface fluxes between the land and atmosphere. By using SIF data to represent the flux, we bypass the need to use soil moisture data from FLUXNET (limited spatially and temporally) or remote sensing (limited by spatial resolution, canopy interference, measurement depth, and radio frequency interference) thus eliminating additional uncertainty. The Granger Causality analysis allows for the determination of the strength of the two-way causal relationship between SIF and several climatic variables: precipitation, radiation and temperature. We determine that warm regions transitioning from water to energy limitation exhibit strong feedbacks between the land surface and atmosphere due to their high sensitivity to climate and weather variability. Tropical rainforest regions show low magnitudes of

    Nurnet - The net of the Nuraghes (http://www.nurnet.it) is a Foundation of Participation aiming to promote the culture of the Pre-Nuragical (3200-2700 BC) and Nuragical period (up to the 2nd century AD) in the island of Sardinia (Italy). It is fed by a net of conventional social connections or through social web- networks empowered by private citizens, agents and public administrations sharing the same goals and interests. CRS4 (Center for Advanced Studies, Research and Development in Sardinia), in collaboration with Nurnet Foundation, developed a geoportal (http://nurnet.crs4.it/nurnetgeo/) on the web, at the moment as a beta version, enable the users to access and share information. The application is based on Geographic Information System (GIS) and Participatory Geographic Information System (PGIS) and it manages several types of information like archaeological sites, artifacts and museum information. Such information comes from the users of the portal and from other sources that make the data available, according to the "open data" philosophy: free data accessible to anyone. The users are encouraged to generate and manage information of archaeological sites in the Italian island of Sardinia about location, history, preservation of the archaeological patrimony, pictures and videos to enrich a wide geo-database pertaining the big heritage of this region in every place there are nuraghes, dolmens domus de janas, menhirs, villages and sacred pits. A specific data model has been created, the geo-attribute is in WGS84 and it can be a point, a line or a polygon. There are three types of actors: viewers, editors and validators. The viewer can query data with a map or a form; the editor can insert and update data through maps using Google or Open Street Map as base layer; the validators are the experts working behind the geoportal: they evaluate and validate the data quality (archaeologists for example). To implement the geoportal, open source software has been used and

Storey, Sebastian Willis, Jojanneke van den Beukel, Jonathan Woodward, James Pollard, Benjamin Wood, Victoria Newton, Jana Virian, Owen Haswell, and Samuel J. Oliver. MEDEX2015: Greater sea-level fitness is associated with lower sense of effort during Himalayan trekking without worse acute mountain sickness. High Alt Med Biol. 18:152-162, 2017.-This study examined the complex relationships of fitness and hypoxic sensitivity with submaximal exercise responses and acute mountain sickness (AMS) at altitude. Determining these relationships is necessary before fitness or hypoxic sensitivity tests can be recommended to appraise individuals' readiness for altitude. Forty-four trekkers (26 men; 18 women; 20-67 years) completed a loaded walking test and a fitness questionnaire in normoxia to measure and estimate sea-level maximal aerobic capacity (maximum oxygen consumption [[Formula: see text]O2max]), respectively. Participants also completed a hypoxic exercise test to determine hypoxic sensitivity (cardiac, ventilatory, and arterial oxygen saturation responses to acute hypoxia, fraction of inspired oxygen [Fio2] = 0.112). One month later, all participants completed a 3-week trek to 5085 m with the same ascent profile. On ascent to 5085 m, ratings of perceived exertion (RPEascent), fatigue by Brunel Mood Scale, and AMS were recorded daily. At 5085 m, RPE during a fixed workload step test (RPEfixed) and step rate during perceptually regulated exercise (STEPRPE35) were recorded. Greater sea-level [Formula: see text]O2max was associated with, and predicted, lower sense of effort (RPEascent; r = -0.43; p < 0.001; RPEfixed; r = -0.69; p < 0.001) and higher step rate (STEPRPE35; r = 0.62; p < 0.01), but not worse AMS (r = 0.13; p = 0.4) or arterial oxygen desaturation (r = 0.07; p = 0.7).

    configuration management policies for distributed applications' present a system in which the configuration of the system in terms of its constituent components and their interconnections can be controlled by reconfiguration rules. Neumair and Wies in the paper `Case study: applying management policies to manage distributed queuing systems' examine how high-level policies can be transformed into practical and efficient implementations for the case of distributed job queuing systems. Koch and Krämer in `Rules and agents for automated management of distributed systems' describe the results of an experiment in using the software development environment Marvel to provide a rule based implementation of management policy. The paper by Jardin, `Supporting scalability and flexibility in a distributed management platform' reports on the experience of using a policy directed approach in the industrial strength TeMIP management platform. Both human managers and automated management components rely on a comprehensive monitoring system to provide accurate and timely information on which decisions are made to modify the operation of a system. The monitoring service must deal with condensing and summarizing the vast amount of data available to produce the events of interest to the controlling components of the overall management system. The paper `Distributed intelligent monitoring and reporting facilities' by Pavlou, Mykoniatis and Sanchez describes a flexible monitoring system in which the monitoring agents themselves are policy directed. Their monitoring system has been implemented in the context of the OSIMIS management platform. Debski and Janas in `The SysMan monitoring service and its management environment' describe the overall SysMan management system architecture and then concentrate on how event processing and distribution is supported in that architecture. The collection of papers gives a good overview of the current state of the art in distributed system management. It has

    The Editor welcomes letters, by e-mail to ped@iop.org or by post to Dirac House, Temple Back, Bristol BS1 6BE Contents: Force on a pendulum Sound slows down Bond is back Force on a pendulum The simple pendulum has been used by several educationalists for investigating the patterns of thinking among students and their observations that Aristotelian thinking persists among students at college level. I had also considered the simple pendulum in my 1985 letter in Physics Today [1], so I was interested to read the test given by Lenka Czudková and Jana Musilová [2]. When students were asked to draw net forces acting on the particle at various positions, 31.9% of students believed that the net force was tangential to the particle's path the whole time. To me this is no surprise because in our derivation of the equation for the period of a simple pendulum we assume that the unbalanced sine component provides the restoring force for the harmonic motion of the bob. Of course, Czudková and Musilová's question asked students for the net force on the particle, not the component. The student's answer fits well with the logic of the equilibrium of forces and the parallelogram law. Lastly, let me bring out the similarity between the student's answer and the thinking of George Gamow. He used to call positrons 'donkey' electrons because of their displacement against the applied force, before Paul Dirac termed them positrons. Victor Weisskeptf told me this anecdote in a letter in May 1982. References [1] Sathe D 1985 Phys. Today 38 144 [2] Czudková L and Musilová J 2000 Phys.

Jennifer Cash (South Carolina U), Lucianne Walkowicz (Adler), and Joe Filipazzo (CUNY) worked with these Full-Frame Images to identify all the sources. The next step is to identify all the stars in the image and perform aperture photometry.There are likely new exoplanets, binary stars, and other interesting variable sources hidden in this dataset.Exoplanets in the WorldWide Telescope (WWT): Did someone say exoplanets?WWT, now run by the AAS, is an open source data visualization tool often used by planetariums to virtually fly around the Universe.David Weigal (Samford U) worked to improve WWT by adding exoplanetary systems. This was tricky, but he was able to demo one example of a planet orbiting a Sirius-like star.Career Paths: Peter Yoachim (UW) and Eric Bellm (Caltech) took different approaches to study career paths in astronomy.
