    ALE (Astronomical LIDAR for Extinction) is deployed at the University of New Mexico's (UNM) Campus Observatory in Albuquerque, NM. It has begun a year-long testing phase prior deployment at McDonald Observatory in support of the CCD/Transit Instrument II (CTI-II). ALE is designed to produce a high-precision measurement of atmospheric absorption and scattering above the observatory site every ten minutes of every moderately clear night. LIDAR (LIght Detection And Ranging) is the VIS/UV/IR analog of radar, using a laser, telescope and time-gated photodetector instead of a radio transmitter, dish and receiver. In the case of ALE -- an elastic backscatter LIDAR -- 20ns-long, eye-safe laser pulses are launched 2500 times per second from a 0.32m transmitting telescope co-mounted with a 50mm short-range receiver on an alt-az mounted 0.67m long-range receiver. Photons from the laser pulse are scattered and absorbed as the pulse propagates through the atmosphere, a portion of which are scattered into the field of view of the short- and long-range receiver telescopes and detected by a photomultiplier. The properties of a given volume of atmosphere along the LIDAR path are inferred from both the altitude-resolved backscatter signal as well as the attenuation of backscatter signal from altitudes above it. We present ALE profiles from the commissioning phase and demonstrate some of the astronomically interesting atmospheric information that can be gleaned from these data, including, but not limited to, total line-of-sight extinction. This project is funded by NSF Grant 0421087.

  3. Establishing a Statistical Link between Network Oscillations and Neural Synchrony.

    Full Text Available Pairs of active neurons frequently fire action potentials or "spikes" nearly synchronously (i.e., within 5 ms of each other. This spike synchrony may occur by chance, based solely on the neurons' fluctuating firing patterns, or it may occur too frequently to be explicable by chance alone. When spike synchrony above chances levels is present, it may subserve computation for a specific cognitive process, or it could be an irrelevant byproduct of such computation. Either way, spike synchrony is a feature of neural data that should be explained. A point process regression framework has been developed previously for this purpose, using generalized linear models (GLMs. In this framework, the observed number of synchronous spikes is compared to the number predicted by chance under varying assumptions about the factors that affect each of the individual neuron's firing-rate functions. An important possible source of spike synchrony is network-wide oscillations, which may provide an essential mechanism of network information flow. To establish the statistical link between spike synchrony and network-wide oscillations, we have integrated oscillatory field potentials into our point process regression framework. We first extended a previously-published model of spike-field association and showed that we could recover phase relationships between oscillatory field potentials and firing rates. We then used this new framework to demonstrate the statistical relationship between oscillatory field potentials and spike synchrony in: 1 simulated neurons, 2 in vitro recordings of hippocampal CA1 pyramidal cells, and 3 in vivo recordings of neocortical V4 neurons. Our results provide a rigorous method for establishing a statistical link between network oscillations and neural synchrony.

    Full Text Available The compelling ideal of modern architectural education associated with Boyer’s (1990 framework is a scholarly collaboration by a relationship between teaching and research. Research enhances teaching through the introduction of new topics and methodologies. Research-based teaching stimulates better communication between students and lecturers as researchers. Students’ comments and questions can improve the subject of future research. A model of research-based teaching can be structured to teach both research findings and processes. This model can be well integrated to current curriculum with emphasis on research-oriented teaching in which students take part in the research process. In this process, instructors use their research experience during their interactions with students. This paper discusses the establishment of the link between research and teaching in the built environment with cases from studio-based learning in Landscape Architecture discipline. The argument is that studio-based education should be accepted as a pedagogical method to take part in teaching research to make connections between architecture and other disciplines. This effort will position the education into a research-based setting and make proposals to re-orient curriculum so that researchers can teach what and how they research.

    It is well established that the development of new technologies for early detection and quantitative monitoring of dental caries at its early stage could provide health and economic benefits ranging from timely preventive interventions to reduction of the time required for clinical trials of anti-caries agents. However, the new technologies currently used in clinical setting cannot assess and monitor caries using the actual mineral concentration within the lesion, while a laboratory-based microcomputed tomography (MCT) has been shown to possess this capability. Thus we envision the establishment of mathematical equations relating the measurements of each of the clinical technologies to that of MCT will enable the mineral concentration of lesions detected and assessed in clinical practice to be extrapolated from the equation, and this will facilitate preventitive care in dentistry to lower treatment cost. We utilize MCT and the two prominent clinical caries assessment devices (Quantitative Light-induced Fluorescence [QLF] and Diagnodent) to longitudinally monitor the development of caries in a continuous flow mixed-organisms biofilm model (artificial mouth), and then used the collected data to establish mathematical equation relating the measurements of each of the clinical technologies to that of MCT. A linear correlation was observed between the measurements of MicroCT and that of QLF and Diagnodent. Thus mineral density in a carious lesion detected and measured using QLF or Diagnodent can be extrapolated using the developed equation. This highlights the usefulness of MCT for monitoring the progress of an early caries being treated with therapeutic agents in clinical practice or trials.

    In the current global positioning system (GPS), the reliability of information transmissions can be enhanced with the aid of inter-satellite links (ISLs) or crosslinks between satellites. Instead of only using conventional radio frequency (RF) crosslinks, the laser crosslinks provide an option to significantly increase the data throughput. The connectivity and robustness of ISL are needed for analysis, especially for GPS constellations with laser crosslinks. In this paper, we first propose a hybrid GPS communication architecture in which uplinks and downlinks are established via RF signals and crosslinks are established via laser links. Then, we design an optical crosslink assignment criteria considering the practical optical communication factors such as optical line- of-sight (LOS) range, link distance, and angular velocity, etc. After that, to further improve the rationality of establishing crosslinks, a topology control algorithm is formulated to optimize GPS crosslink networks at both physical and network layers. The RF transmission features for uplink and downlink and optical transmission features for crosslinks are taken into account as constraints for the optimization problem. Finally, the proposed link establishment criteria are implemented for GPS communication with optical crosslinks. The designs of this paper provide a potential crosslink establishment and topology control algorithm for the next generation GPS.

    The Brooklyn Traffic Real-Time Ambient Pollutant Penetration and Environmental Dispersion (B-TRAPPED) study, conducted in Brooklyn, NY, USA, in 2005, was designed with multiple goals in mind, two of which were contaminant source characterization and street canyon transport and dispersion monitoring. In the portion of the study described here, synchronized wind velocity and azimuth as well as particulate matter (PM) concentrations at multiple locations along 33rd Street were used to determine the feasibility of using traffic emissions in a complex urban topography as a sole tracer for studying urban contaminant transport. We demonstrate in this paper that it is possible to link downwind concentrations of contaminants in an urban street canyon to the vehicular traffic cycle using Eigen-frequency analysis. In addition, multivariable circular histograms are used to establish directional frequency maxima for wind velocity and contaminant concentration.

    Full Text Available Transcranial focused ultrasound (FUS is capable of modulating the neural activity of specific brain regions, with a potential role as a non-invasive computer-to-brain interface (CBI. In conjunction with the use of brain-to-computer interface (BCI techniques that translate brain function to generate computer commands, we investigated the feasibility of using the FUS-based CBI to non-invasively establish a functional link between the brains of different species (i.e. human and Sprague-Dawley rat, thus creating a brain-to-brain interface (BBI. The implementation was aimed to non-invasively translate the human volunteer's intention to stimulate a rat's brain motor area that is responsible for the tail movement. The volunteer initiated the intention by looking at a strobe light flicker on a computer display, and the degree of synchronization in the electroencephalographic steady-state-visual-evoked-potentials (SSVEP with respect to the strobe frequency was analyzed using a computer. Increased signal amplitude in the SSVEP, indicating the volunteer's intention, triggered the delivery of a burst-mode FUS (350 kHz ultrasound frequency, tone burst duration of 0.5 ms, pulse repetition frequency of 1 kHz, given for 300 msec duration to excite the motor area of an anesthetized rat transcranially. The successful excitation subsequently elicited the tail movement, which was detected by a motion sensor. The interface was achieved at 94.0±3.0% accuracy, with a time delay of 1.59±1.07 sec from the thought-initiation to the creation of the tail movement. Our results demonstrate the feasibility of a computer-mediated BBI that links central neural functions between two biological entities, which may confer unexplored opportunities in the study of neuroscience with potential implications for therapeutic applications.

    In an air-to-ground free-space optical communication system, strong background interference seriously affects the beacon detection, which makes it difficult to establish the optical link. In this paper, we propose a correlation beacon detection scheme under strong background interference conditions. As opposed to traditional beacon detection schemes, the beacon is modulated by an m-sequence at the transmitting terminal with a digital differential matched filter (DDMF) array introduced at the receiving end to detect the modulated beacon. This scheme is capable of suppressing both strong interference and noise by correlation reception of the received image sequence. In addition, the DDMF array enables each pixel of the image sensor to have its own DDMF of the same structure to process its received image sequence in parallel, thus it makes fast beacon detection possible. Theoretical analysis and an outdoor experiment have been demonstrated and show that the proposed scheme can realize fast and effective beacon detection under strong background interference conditions. Consequently, the required beacon transmission power can also be reduced dramatically.

    The mechanisms that contribute to the development of chronic ankle instability are not understood. Investigators have developed a hypothetical model in which neuromuscular alterations that stem from damaged ankle ligaments are thought to affect periarticular and proximal muscle activity. However, the retrospective nature of these studies does not allow a causal link to be established. To assess temporal alterations in the activity of 2 periarticular muscles of the rat ankle and 2 proximal muscles of the rat hind limb after an ankle sprain. Controlled laboratory study. Laboratory. Five healthy adult male Long Evans rats (age = 16 weeks, mass = 400.0 ± 13.5 g). Indwelling fine-wire electromyography (EMG) electrodes were implanted surgically into the biceps femoris, medial gastrocnemius, vastus lateralis, and tibialis anterior muscles of the rats. We recorded baseline EMG measurements while the rats walked on a motor-driven treadmill and then induced a closed lateral ankle sprain by overextending the lateral ankle ligaments. After ankle sprain, the rats were placed on the treadmill every 24 hours for 7 days, and we recorded postsprain EMG data. Onset time of muscle activity, phase duration, sample entropy, and minimal detectable change (MDC) were assessed and compared with baseline using 2-tailed dependent t tests. Compared with baseline, delayed onset time of muscle activity was exhibited in the biceps femoris (baseline = -16.7 ± 54.0 milliseconds [ms]) on day 0 (5.2 ± 64.1 ms; t 4 = -4.655, P = .043) and tibialis anterior (baseline = 307.0 ± 64.2 ms) muscles on day 3 (362.5 ± 55.9 ms; t 4 = -5.427, P = .03) and day 6 (357.3 ± 39.6 ms; t 4 = -3.802, P = .02). Longer phase durations were observed for the vastus lateralis (baseline = 321.9 ± 92.6 ms) on day 3 (401.3 ± 101.2 ms; t 3 = -4.001, P = .03), day 4 (404.1 ± 93.0 ms; t 3 = -3.320, P = .048), and day 5 (364.6 ± 105.2 ms; t 3 = -3.963, P = .03) and for the tibialis anterior (baseline = 103.9 ± 16.4 ms

A sample of children (N = 1264) aged 10-12 years completed the questionnaire and the "Athens Coping Scale". Multiple fit indices provided support that the 9-factor model had a good fit to the data. Reliability coefficients ranged from .68 to .83. The study provided also preliminary evidence of convergent validity of the "Dimensions of Academic Hardiness" scores with one theoretically related measure, the "Athens Coping Scale". The results enrich the notion of Academic Hardiness in late elementary school children as the role of awareness and the role of children's previous experiences has been distinguished. The relation between the "Dimensions of Academic Hardiness" and achievement goal orientations in children learning is also noted. These findings are discussed in the context of the relevant literature.

    Here, we present a novel method for the solution of the diffusion equation on a composite AMR mesh. This approach is suitable for including diffusion based physics modules to hydrocodes that support ALE and AMR capabilities. To illustrate, we proffer our implementations of diffusion based radiation transport and heat conduction in a hydrocode called ALE-AMR. Numerical experiments conducted with the diffusion solver and associated physics packages yield 2nd order convergence in the L2 norm.

    The increasing need to communicate to exchange data can be handled by personal microcomputers. The necessity for the transference of information stored in one type of personal computer to another type of personal computer is often encountered in the process of integrating multiple sources of information stored in different and incompatible computers in Medical Research and Practice. A practical example is demonstrated with two relatively inexpensive commonly used computers, the IBM PC jr. and the Apple IIe. The basic input/output (I/O) interface chip for serial communication for each computer are joined together using a Null connector and cable to form a communications link. Using BASIC (Beginner's All-purpose Symbolic Instruction Code) Computer Language and the Disk Operating System (DOS) the communications handshaking protocol and file transfer is established between the two computers. The BASIC programming languages used are Applesoft (Apple Personal Computer) and PC BASIC (IBM Personal computer).

    Full Text Available Blooms of the benthic dinoflagellate Ostreopsis have been related to sporadic acute respiratory symptoms and general malaise in people exposed to marine aerosols on some Mediterranean beaches. However, the direct link between recurrent Ostreopsis blooms and health problems has not been clearly established. In order to establish and elucidate the connection, we conducted a joint ecology and epidemiology study in an Ostreopsis hot spot. Throughout the bloom, which extended from the end of June until the end of October 2013, 81% of the human cohort that we studied experienced at least one Ostreopsis-related symptom. Paradoxically, the time when the effects were greatest was during a short time window in early August. This corresponded to the transition from the exponential growth to the stationary phase of the bloom. Negligible symptoms were reported from August to mid-October, during the stationary period of the proliferation, when O. cf. ovata maintained high concentrations of epiphytic cells. No clear patterns in the landward wind component were noted during the time when health effects were greatest. Our main hypothesis is that the irritants present in the aerosol are produced during a particular physiological phase of the Ostreopsis cells during the bloom.

    In 1848 pharmacist Horváth Mihály established the first pharmacy in Aleşd, called Speranţa (Remény). Following the brief history of this pharmacy we will notice that in 1874 the pharmacy comes into the possession of Kocsiss József. In 1906 the personal rights of the pharmacy are transcribed to Kocsiss Béla, and since 1938 the his son, Kocsiss Dezső, pharmacist, became the new owner. In 1949 the pharmacy was nationalized and became the property of the Pharmaceutical Office Oradea, the pharmacy got the name Farmacia nr. 22 of Aleşd, and continued its activity throughout the whole communist period. Starting with the year 1991 it entered into private system as Angefarm, as the property of Mermeze Gheorghe, pharmacist, and from 2003 until now works under the name Vitalogy 3, as the property of Ghitea Sorin. A second pharmacy, Sfântul Anton was founded in 1937 by pharmacist Herceg Dobreanu Atena, which however had no continuity during the communist period.

  3. Coastal Improvements for Tide Models: The Impact of ALES Retracker

    Full Text Available Since the launch of the first altimetry satellites, ocean tide models have been improved dramatically for deep and shallow waters. However, issues are still found for areas of great interest for climate change investigations: the coastal regions. The purpose of this study is to analyze the influence of the ALES coastal retracker on tide modeling in these regions with respect to a standard open ocean retracker. The approach used to compute the tidal constituents is an updated and along-track version of the Empirical Ocean Tide model developed at DGFI-TUM. The major constituents are derived from a least-square harmonic analysis of sea level residuals based on the FES2014 tide model. The results obtained with ALES are compared with the ones estimated with the standard product. A lower fitting error is found for the ALES solution, especially for distances closer than 20 km from the coast. In comparison with in situ data, the root mean squared error computed with ALES can reach an improvement larger than 2 cm at single locations, with an average impact of over 10% for tidal constituents K 2 , O 1 , and P 1 . For Q 1 , the improvement is over 25%. It was observed that improvements to the root-sum squares are larger for distances closer than 10 km to the coast, independently on the sea state. Finally, the performance of the solutions changes according to the satellite’s flight direction: for tracks approaching land from open ocean root mean square differences larger than 1 cm are found in comparison to tracks going from land to ocean.

  4. Affective mapping: An activation likelihood estimation (ALE) meta-analysis.

    Functional neuroimaging has the spatial resolution to explain the neural basis of emotions. Activation likelihood estimation (ALE), as opposed to traditional qualitative meta-analysis, quantifies convergence of activation across studies within affective categories. Others have used ALE to investigate a broad range of emotions, but without the convenience of the BrainMap database. We used the BrainMap database and analysis resources to run separate meta-analyses on coordinates reported for anger, anxiety, disgust, fear, happiness, humor, and sadness. Resultant ALE maps were compared to determine areas of convergence between emotions, as well as to identify affect-specific networks. Five out of the seven emotions demonstrated consistent activation within the amygdala, whereas all emotions consistently activated the right inferior frontal gyrus, which has been implicated as an integration hub for affective and cognitive processes. These data provide the framework for models of affect-specific networks, as well as emotional processing hubs, which can be used for future studies of functional or effective connectivity.

  5. Time-Discrete Higher-Order ALE Formulations: Stability

    KAUST Repository

    Bonito, Andrea

    2013-01-01

    Arbitrary Lagrangian Eulerian (ALE) formulations deal with PDEs on deformable domains upon extending the domain velocity from the boundary into the bulk with the purpose of keeping mesh regularity. This arbitrary extension has no effect on the stability of the PDE but may influence that of a discrete scheme. We examine this critical issue for higher-order time stepping without space discretization. We propose time-discrete discontinuous Galerkin (dG) numerical schemes of any order for a time-dependent advection-diffusion-model problem in moving domains, and study their stability properties. The analysis hinges on the validity of the Reynold\\'s identity for dG. Exploiting the variational structure and assuming exact integration, we prove that our conservative and nonconservative dG schemes are equivalent and unconditionally stable. The same results remain true for piecewise polynomial ALE maps of any degree and suitable quadrature that guarantees the validity of the Reynold\\'s identity. This approach generalizes the so-called geometric conservation law to higher-order methods. We also prove that simpler Runge-Kutta-Radau methods of any order are conditionally stable, that is, subject to a mild ALE constraint on the time steps. Numerical experiments corroborate and complement our theoretical results. © 2013 Society for Industrial and Applied Mathematics.

    We construct a new family of classical BPS solutions of type IIB supergravity describing 3-branes transverse to a 6-dimensional space with topology R 2 xALE. They are characterized by a non-trivial flux of the supergravity 2-forms through the homology 2-cycles of a generic smooth ALE manifold. Our solutions have two Killing spinors and thus preserve N=2 supersymmetry. They are expressed in terms of a quasi harmonic function H (the 'warp factor'), whose properties we study in the case of the simplest ALE, namely the Eguchi-Hanson manifold. The equation for H is identified as an instance of the confluent Heun equation. We write explicit power series solutions and solve the recurrence relation for the coefficients, discussing also the relevant asymptotic expansions. While, as in all such N=2 solutions, supergravity breaks down near the brane, the smoothing out of the vacuum geometry has the effect that the warp factor is regular in a region near the cycle. We interpret the behavior of the warp factor as describing a three-brane charge 'smeared' over the cycle and consider the asymptotic form of the geometry in that region, showing that conformal invariance is broken even when the complex type IIB 3-form field strength is assumed to vanish. We conclude with a discussion of the basic features of the gauge theory dual

    Cysteine residues introduced at specific locations in the aspartate receptor of Salmonella typhimurium provide anchor points for cross-linking and serve as chemical markers for structural studies of this oligomeric receptor. These markers have been used to measure the rate of subunit exchange between oligomeric receptors and to show that ligand binding inhibits this exchange. The cysteine-containing receptors can be oxidatively cross-linked to completion within the oligomeric receptor, indicating that the receptor has an even number of subunits. Based on this observation, a technique has been developed that can be used to determine the oligomeric structure of proteins under a variety of experimental conditions. The technique involves the measurement of the effect of dilution by cysteineless receptor subunits on cross-linking and reveals that the aspartate receptor is dimeric in detergent solution, in a mixed-micelle system, and in reconstituted membrane vesicles. Binding of aspartate does not change the oligomeric structure of the receptor, indicating that transmembrane signaling occurs within an oligomeric receptor of constant size

    The chemical composition of the gases emitted from a hornito close to the active lava lake of Erta'Ale, Ethiopia, as derived from chemical analyses on 18 samples collected on 23 January 1974, was found to be (in mol-percent): H/sub 2/O: 79.4; CO/sub 2/: 10.4, total S: 7.36, HCl: 0.42, H/sub 2/: 1.49, N/sub 2/: 0.18, Ar: 0.001, CO: 0.46, and COS: 0.009. Thermodynamic considerations, based on the equilibria CO/sub 2/ + H/sub 2/ reversible CO + H/sub 2/O and CO/sub 2/ + 3H/sub 2/ + SO/sub 2/ reversible COS + 3H/sub 2/O show that the analytical values represent the equilibrium composition of a gas mixture at the measured temperature of around 1130/sup 0/C under close to the surface pressure conditions. Comparison of the Erta'Ale gas emissions with those from other volcanoes suggests a close similarity in their chemical composition. This similarity is considered to be due to common processes governing the release of gaseous species from a magma.

    Previous research has shown that voters' perception of electoral fairness has an impact on their attitudes and behaviors. However, less research has attempted to link objective measurements of electoral integrity on voters' attitudes about the democratic process. Drawing on data from the Comparative Study of Electoral Systems and the Quality of Elections Data, we investigate whether cross-national differences in electoral integrity have significant influences on citizens' level of satisfaction with democracy. We hypothesize that higher levels of observed electoral fraud will have a negative impact on evaluations of the democratic process, and that this effect will be mediated by a respondent's status as a winner or loser of an election. The article's main finding is that high levels of electoral fraud are indeed linked to less satisfaction with democracy. However, we show that winning only matters in elections that are conducted in an impartial way. The moment elections start to display the telltale signs of manipulation and malpractice, winning and losing no longer have different effects on voter's levels of satisfaction with democracy.

    Extending research based on newlywed couples, this study investigated longitudinal associations between marital satisfaction and depressive symptoms in a community sample of 296 couples in established relationships (M = 13.25 years, SD = 5.98) with children (M age = 11.05 years, SD = 2.31). Support was found for reciprocal relations between marital satisfaction and depressive symptoms in couples with established relationships. Further extending previous work, the study showed that relationship length and hostile marital conflict were significant moderators of these linkages. Husbands in longer term relationships were more vulnerable to depressive symptoms in the context of marital problems compared with husbands in shorter term relationships. At higher levels of marital conflict, the negative relationship between marital satisfaction and depressive symptoms was strengthened. Reflecting an unexpected finding, increased conflict buffered spouses from marital dissatisfaction in the context of depressive symptoms. Copyright 2008 APA, all rights reserved.

    Full Text Available The aim of the paper is to highlight the changing role of archives and to use the case study to indicate the lacking communication with students due to the absence of PR activities, as well as to point to the difficulties of access to digital archival materials needed for student research. Using PR strategies the archives can sensitise the public for its material through different public programmes, exhibitions and fostering goodmedia relations. The archives try to develop good relations with target groups, in this case with students as potential users, taking into consideration their research needs and materials they are interested in. Research findings on student needs for archival data are extremely rare, even in recent American research. Therefore, we conducted this research using a questionnaire for students of four departments of the University of Zadar (geography, history, art history, tourism and communication, who were users of the State Archives in Zadar. The research results show whether the subjects use archival material, for what purposes, and what other resources they used prior to archival material. It also provides information on the level of familiarity with online archival material and use of web pages with archival resources. We can conclude that the students in Zadar are not well acquainted with the digital resources and use them rarely for their research purposes. The situation can be improved by having the State Archives in Zadar take a more proactive role in identifying target groups of students, their user profiles, difficulties they face, and by allowing a more flexible access to archival material. In addition to goo d relations with the Department of Information Sciences, the Archives should foster links with other departments and include them in planning and implementation of their programmes.

  13. A Cell-Centered Multiphase ALE Scheme With Structural Coupling

    Energy Technology Data Exchange (ETDEWEB)

    Dunn, Timothy Alan [Univ. of California, Davis, CA (United States)

    2012-04-16

    A novel computational scheme has been developed for simulating compressible multiphase flows interacting with solid structures. The multiphase fluid is computed using a Godunov-type finite-volume method. This has been extended to allow computations on moving meshes using a direct arbitrary-Eulerian- Lagrangian (ALE) scheme. The method has been implemented within a Lagrangian hydrocode, which allows modeling the interaction with Lagrangian structural regions. Although the above scheme is general enough for use on many applications, the ultimate goal of the research is the simulation of heterogeneous energetic material, such as explosives or propellants. The method is powerful enough for application to all stages of the problem, including the initial burning of the material, the propagation of blast waves, and interaction with surrounding structures. The method has been tested on a number of canonical multiphase tests as well as fluid-structure interaction problems.

  14. An Invariant-Preserving ALE Method for Solids under Extreme Conditions

    Energy Technology Data Exchange (ETDEWEB)

    2012-07-17

    We are proposing a fundamentally new approach to ALE methods for solids undergoing large deformation due to extreme loading conditions. Our approach is based on a physically-motivated and mathematically rigorous construction of the underlying Lagrangian method, vector/tensor reconstruction, remapping, and interface reconstruction. It is transformational because it deviates dramatically from traditionally accepted ALE methods and provides the following set of unique attributes: (1) a three-dimensional, finite volume, cell-centered ALE framework with advanced hypo-/hyper-elasto-plastic constitutive theories for solids; (2) a new physically and mathematically consistent reconstruction method for vector/tensor fields; (3) advanced invariant-preserving remapping algorithm for vector/tensor quantities; (4) moment-of-fluid (MoF) interface reconstruction technique for multi-material problems with solids undergoing large deformations. This work brings together many new concepts, that in combination with emergent cell-centered Lagrangian hydrodynamics methods will produce a cutting-edge ALE capability and define a new state-of-the-art. Many ideas in this work are new, completely unexplored, and hence high risk. The proposed research and the resulting algorithms will be of immediate use in Eulerian, Lagrangian and ALE codes under the ASC program at the lab. In addition, the research on invariant preserving reconstruction/remap of tensor quantities is of direct interest to ongoing CASL and climate modeling efforts at LANL. The application space impacted by this work includes Inertial Confinement Fusion (ICF), Z-pinch, munition-target interactions, geological impact dynamics, shock processing of powders and shaped charges. The ALE framework will also provide a suitable test-bed for rapid development and assessment of hypo-/hyper-elasto-plastic constitutive theories. Today, there are no invariant-preserving ALE algorithms for treating solids with large deformations. Therefore

  15. Why Seedlings Die: Linking Carbon and Water Limitations to Mechanisms of Mortality During Establishment in Conifer Seedlings

    Reinhardt, K.; Germino, M. J.; Kueppers, L. M.; Mitton, J.; Castanha, C.

    2012-12-01

    BACKGROUND Recent ecophysiological studies aimed at explaining adult tree mortality during drought have examined the carbon (C)-exhaustion compared to the hydraulic-failure hypotheses for death. Prolonged drought leads to durations of stomatal closure (and thus limited C gain), which could result in long periods of negative C balance and fatal reductions in whole-plant C reserves (i.e., available non-structural carbohydrates ["NSC"]). Alternatively, C reserves may not decrease much but could become increasingly inaccessible to sink tissues in long dry-periods due to impediments to translocation of photosynthate (e.g., through disruption of hydrostatic pressure flow in phloem). As C reserves decline or become inaccessible, continued maintenance respiration has been hypothesized to lead to exhaustion of NSC after extended durations of drought, especially in isohydric plant species. On the other hand, hydraulic failure (e.g., catastrophic xylem embolisms) during drought may be the proximate cause of death, occurring before true C starvation occurs. Few studies have investigated specifically the mechanism(s) of tree death, and no published studies that we know of have quantified changes in NSC during mortality. EXPERIMENTAL DESIGN AND HYPOTHESES We conducted two studies that investigated whole-tree and tissue-specific C relations (photosynthetic C gain, respiration, dry-mass gain, and NSC pools) in Pinus flexilis seedlings during the initial establishment phase, which is characterized by progressive drought during summer. We measured survival, growth and biomass allocation, and C-balance physiology (photosynthetic C-gain and chlorophyll fluorescence, respiration C-use, and NSC concentrations) from germination to mortality. We hypothesized that 1) stomatal and biochemical limitations to C gain would constrain seedling survival (through inadequate seasonal C-balance), as has been shown for conifer seedlings near alpine treeline; 2) hydraulic constraints (embolisms and

    This report details continuing validation efforts for the Sphere and Tunnel (STUN) and ALE3D codes. STUN has been validated previously for blast propagation through tunnels using several sets of experimental data with varying charge sizes and tunnel configurations, including the MARVEL nuclear driven shock tube experiment (Glenn, 2001). The DHS-funded STUNTool version is compared to experimental data and the LLNL ALE3D hydrocode. In this particular study, we compare the performance of the STUN and ALE3D codes in modeling an in-tunnel airblast to experimental results obtained by Lunderman and Ohrt in a series of small-scale high explosive experiments (1997).

  3. +2.71 LOD score at zero recombination is not sufficient for establishing linkage between X-linked mental retardation and X-chromosome markers

    1996-07-12

    Nonspecific X-linked mental retardation (MRX) is the denomination attributed to the familial type of mental retardation compatible with X-linked inheritance but lacking specific phenotypic manifestations. It is thus to be expected that families falling under such broad definition are genetically heterogeneous in the sense that they may be due to different types of mutations occurring, most probably, at distinct X-chromosome loci. To facilitate a genetic classification of these conditions, the Nomenclature Committee of the Eleventh Human Gene Mapping Workshop proposed to assign a unique MRX-serial number to each family where evidence of linkage with one or more X-chromosome markers had been established with a LOD score of at least +2 at zero recombination. This letter is meant to emphasize the inadequacy of this criterion for a large pedigree where the segregation of the disease has been evaluated against the haplotype constitution of the entire X-chromosome carrying the mutation in question. 12 refs., 2 figs., 1 tab.

  4. Brewhouse-resident microbiota are responsible for multi-stage fermentation of American coolship ale.

    Directory of Open Access Journals (Sweden)

    Nicholas A Bokulich

    Full Text Available American coolship ale (ACA is a type of spontaneously fermented beer that employs production methods similar to traditional Belgian lambic. In spite of its growing popularity in the American craft-brewing sector, the fermentation microbiology of ACA has not been previously described, and thus the interface between production methodology and microbial community structure is unexplored. Using terminal restriction fragment length polymorphism (TRFLP, barcoded amplicon sequencing (BAS, quantitative PCR (qPCR and culture-dependent analysis, ACA fermentations were shown to follow a consistent fermentation progression, initially dominated by Enterobacteriaceae and a range of oxidative yeasts in the first month, then ceding to Saccharomyces spp. and Lactobacillales for the following year. After one year of fermentation, Brettanomyces bruxellensis was the dominant yeast population (occasionally accompanied by minor populations of Candida spp., Pichia spp., and other yeasts and Lactobacillales remained dominant, though various aerobic bacteria became more prevalent. This work demonstrates that ACA exhibits a conserved core microbial succession in absence of inoculation, supporting the role of a resident brewhouse microbiota. These findings establish this core microbial profile of spontaneous beer fermentations as a target for production control points and quality standards for these beers.

    We derive optimal a priori error estimates for discontinuous Galerkin (dG) time discrete schemes of any order applied to an advection-diffusion model defined on moving domains and written in the Arbitrary Lagrangian Eulerian (ALE) framework. Our estimates hold without any restrictions on the time steps for dG with exact integration or Reynolds\\' quadrature. They involve a mild restriction on the time steps for the practical Runge-Kutta-Radau methods of any order. The key ingredients are the stability results shown earlier in Bonito et al. (Time-discrete higher order ALE formulations: stability, 2013) along with a novel ALE projection.

  10. A coupling of empirical explosive blast loads to ALE air domains in LS-DYNA (registered)

    International Nuclear Information System (INIS)

    Slavik, Todd P

    2010-01-01

    A coupling method recently implemented in LS-DYNA (registered) allows empirical explosive blast loads to be applied to air domains treated with the multi-material arbitrary Lagrangian-Eulerian (ALE) formulation. Previously, when simulating structures subjected to blast loads, two methods of analysis were available: a purely Lagrangian approach or one involving the ALE and Lagrangian formulations coupled with a fluid-structure interaction (FSI) algorithm. In the former, air blast pressure is computed with empirical equations and directly applied to Lagrangian elements of the structure. In the latter approach, the explosive as well as the air are explicitly modeled and the blast wave propagating through the ALE air domain impinges on the Lagrangian structure through FSI. Since the purely Lagrangian approach avoids modeling the air between the explosive and structure, a significant computational cost savings can be realized - especially so when large standoff distances are considered. The shortcoming of the empirical blast equations is their inability to account for focusing or shadowing of the blast waves due to their interaction with structures which may intervene between the explosive and primary structure of interest. The new method presented here obviates modeling the explosive and air leading up the structure. Instead, only the air immediately surrounding the Lagrangian structures need be modeled with ALE, while effects of the far-field blast are applied to the outer face of that ALE air domain with the empirical blast equations; thus, focusing and shadowing effects can be accommodated yet computational costs are kept to a minimum. Comparison of the efficiency and accuracy of this new method with other approaches shows that the ability of LS-DYNA (registered) to model a variety of new blast scenarios has been greatly extended.

    BACKGROUND: It is well known that brewer’s yeast affects the taste and aroma of beer. However, the influence of brewer’s yeast on the protein composition of beer is currently unknown. In this study, changes of the proteome of immature beer, i.e. beer that has not been matured after fermentation......, by ale brewer’s yeast strains with different abilities to degrade fermentable sugars were investigated. RESULTS: Beers were fermented from standard hopped wort (13° Plato) using two ale brewer’s yeast (Saccharomyces cerevisiae) strains with different attenuation degrees. Both immature beers had the same....... These three proteins, all derived from yeast, were identified as cell wall associated proteins, that is Exg1 (an exo-β-1,3-glucanase), Bgl2 (an endo-β-1,2-glucanase), and Uth1 (a cell wall biogenesis protein). CONCLUSION: Yeast strain dependent changes in the immature beer proteome were identified, i.e. Bgl2...

  12. Establishing a common metric for depressive symptoms: linking the BDI-II, CES-D, and PHQ-9 to PROMIS depression.

    Interest in measuring patient-reported outcomes has increased dramatically in recent decades. This has simultaneously produced numerous assessment options and confusion. In the case of depressive symptoms, there are many commonly used options for measuring the same or a very similar concept. Public and professional reporting of scores can be confused by multiple scale ranges, normative levels, and clinical thresholds. A common reporting metric would have great value and can be achieved when similar instruments are administered to a single sample and then linked to each other to produce cross-walk score tables (e.g., Dorans, 2007; Kolen & Brennan, 2004). Using multiple procedures based on item response theory and equipercentile methods, we produced cross-walk tables linking 3 popular "legacy" depression instruments-the Center for Epidemiologic Studies Depression Scale (Radloff, 1977; N = 747), the Beck Depression Inventory-II (Beck, Steer, & Brown, 1996; N = 748), and the 9-item Patient Health Questionnaire (Kroenke, Spitzer, & Williams, 2001; N = 1,120)-to the depression metric of the National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS; Cella et al., 2010). The PROMIS Depression metric is centered on the U.S. general population, matching the marginal distributions of gender, age, race, and education in the 2000 U.S. census (Liu et al., 2010). The linking relationships were evaluated by resampling small subsets and estimating confidence intervals for the differences between the observed and linked PROMIS scores; in addition, PROMIS cutoff scores for depression severity were estimated to correspond with those commonly used with the legacy measures. Our results allow clinicians and researchers to retrofit existing data of 3 popular depression measures to the PROMIS Depression metric and vice versa.

    Belgian red-brown acidic ales are sour and alcoholic fermented beers, which are produced by mixed-culture fermentation and blending. The brews are aged in oak barrels for about two years, after which mature beer is blended with young, non-aged beer to obtain the end-products. The present study evaluated the microbial community diversity of Belgian red-brown acidic ales at the end of the maturation phase of three subsequent brews of three different breweries. The microbial diversity was compared with the metabolite composition of the brews at the end of the maturation phase. Therefore, mature brew samples were subjected to 454 pyrosequencing of the 16S rRNA gene (bacteria) and the internal transcribed spacer region (yeasts) and a broad range of metabolites was quantified. The most important microbial species present in the Belgian red-brown acidic ales investigated were Pediococcus damnosus, Dekkera bruxellensis, and Acetobacter pasteurianus. In addition, this culture-independent analysis revealed operational taxonomic units that were assigned to an unclassified fungal community member, Candida, and Lactobacillus. The main metabolites present in the brew samples were L-lactic acid, D-lactic acid, and ethanol, whereas acetic acid was produced in lower quantities. The most prevailing aroma compounds were ethyl acetate, isoamyl acetate, ethyl hexanoate, and ethyl octanoate, which might be of impact on the aroma of the end-products.

  14. Compatible, energy conserving, bounds preserving remap of hydrodynamic fields for an extended ALE scheme

    2018-02-01

    From the very origins of numerical hydrodynamics in the Lagrangian work of von Neumann and Richtmyer [83], the issue of total energy conservation as well as entropy production has been problematic. Because of well known problems with mesh deformation, Lagrangian schemes have evolved into Arbitrary Lagrangian-Eulerian (ALE) methods [39] that combine the best properties of Lagrangian and Eulerian methods. Energy issues have persisted for this class of methods. We believe that fundamental issues of energy conservation and entropy production in ALE require further examination. The context of the paper is an ALE scheme that is extended in the sense that it permits cyclic or periodic remap of data between grids of the same or differing connectivity. The principal design goals for a remap method then consist of total energy conservation, bounded internal energy, and compatibility of kinetic energy and momentum. We also have secondary objectives of limiting velocity and stress in a non-directional manner, keeping primitive variables monotone, and providing a higher than second order reconstruction of remapped variables. In particular, the new contributions fall into three categories associated with: energy conservation and entropy production, reconstruction and bounds preservation of scalar and tensor fields, and conservative remap of nonlinear fields. The paper presents a derivation of the methods, details of implementation, and numerical results for a number of test problems. The methods requires volume integration of polynomial functions in polytopal cells with planar facets, and the requisite expressions are derived for arbitrary order.

    Understanding the magmatic systems beneath rift volcanoes provides insights into the deeper processes associated with rift architecture and development. At the slow spreading Erta Ale segment (Afar, Ethiopia) transition from continental rifting to seafloor spreading is ongoing on land. A lava lake has been documented since the twentieth century at the summit of the Erta Ale volcano and acts as an indicator of the pressure of its magma reservoir. However, the structure of the plumbing system of the volcano feeding such persistent active lava lake and the mechanisms controlling the architecture of magma storage remain unclear. Here, we combine high-resolution satellite optical imagery and radar interferometry (InSAR) to infer the shape, location and orientation of the conduits feeding the 2017 Erta Ale eruption. We show that the lava lake was rooted in a vertical dike-shaped reservoir that had been inflating prior to the eruption. The magma was subsequently transferred into a shallower feeder dike. We also find a shallow, horizontal magma lens elongated along axis inflating beneath the volcano during the later period of the eruption. Edifice stress modeling suggests the hydraulically connected system of horizontal and vertical thin magmatic bodies able to open and close are arranged spatially according to stresses induced by loading and unloading due to topographic changes. Our combined approach may provide new constraints on the organization of magma plumbing systems beneath volcanoes in continental and marine settings.

  17. Parallel Dynamic Analysis of a Large-Scale Water Conveyance Tunnel under Seismic Excitation Using ALE Finite-Element Method

    2016-01-01

    Full Text Available Parallel analyses about the dynamic responses of a large-scale water conveyance tunnel under seismic excitation are presented in this paper. A full three-dimensional numerical model considering the water-tunnel-soil coupling is established and adopted to investigate the tunnel’s dynamic responses. The movement and sloshing of the internal water are simulated using the multi-material Arbitrary Lagrangian Eulerian (ALE method. Nonlinear fluid–structure interaction (FSI between tunnel and inner water is treated by using the penalty method. Nonlinear soil-structure interaction (SSI between soil and tunnel is dealt with by using the surface to surface contact algorithm. To overcome computing power limitations and to deal with such a large-scale calculation, a parallel algorithm based on the modified recursive coordinate bisection (MRCB considering the balance of SSI and FSI loads is proposed and used. The whole simulation is accomplished on Dawning 5000 A using the proposed MRCB based parallel algorithm optimized to run on supercomputers. The simulation model and the proposed approaches are validated by comparison with the added mass method. Dynamic responses of the tunnel are analyzed and the parallelism is discussed. Besides, factors affecting the dynamic responses are investigated. Better speedup and parallel efficiency show the scalability of the parallel method and the analysis results can be used to aid in the design of water conveyance tunnels.

    The success of efforts to prevent continued transmission of the human immunodeficiency virus (HIV) and to increase compliance with HIV prophylactic interventions among homosexual and bisexual men will depend in part on health care professionals' understanding of and ability to establish linkages with these men. In order to recruit men into a research project and an educational program, staff at the Pitt Men's Study, an epidemiological investigation of HIV infection, developed a process described here as "brokering," which was based on community organizing and marketing principles. Brokering is a dynamic process by which researchers and public health professionals exchange goods and services with formal and informal leaders of the gay community in order to establish strong, long-term linkages. To date, this process yielded 2,989 homosexual and bisexual recruits into the study, which began in 1983. After 8 years, 79% of those still alive continue to return for follow-up. While recruitment techniques will need to vary from city to city, the importance of establishing linkages with the local indigenous leadership remains of major importance.

  19. The Relationship between Language Functions and Character Types in "Noon- Valghalam" by Jalal-Ale-Ahmad

    Full Text Available Making harmony among language functions of story characters with their character types, is one of the characteristics and advantages of modern and successful story writing. In traditional storied literature in Iran (prose and verse, this point is not considered important and story characters, generally, tell in narrator or writers way of speaking and since there is the narrators statement, they are not the representativeness of their class and character type. Not paying attention to this subject, causes disorder in either making supposition of reality or personifying, which are both important principals of story telling. This study, identifies the story of " Noon Val Ghalam" of Jalal- Ale- Ahmad who is a contemporary writer aspect. The methodology is qualitative, and data collection is based on content–analysis and document- analysis. As Ale- Ahmad was one of the Iranian contemporary writers and was familiar with western and Iranian writers, he was expected that the language and way of describing story characters he made, be based on the social class. But this study, by stating different proofs, shows that, this writer ignores the relationship necessary for language functions and character type among characters in the story and because of the imposition of his knowledge, statement and political and social view, the independence of the protagonists in his story is not well-concidered. The inflection of political and social thoughts of each writer among his works, is not a shortfall by it self, but representing of speeches in protagonists, in the way which is not in harmony with their characters, lowering the importance of then is based or an instrument for specific social and political representatives. This action not only shows the character. The specific characters, but also disorders the processing of one important issue in story conversation. Since in each language people from different social groups, use almost the same vocabularies that

    The management of natural hazards involves, as generally known, the four stages of the risk management cycle: Prevention, preparedness, response and recovery. Accordingly, the mitigation of disasters can be performed in terms of short-term and long-term purposes. Whereas emergency management or civil protection helps to strengthen a community's capacity to be better prepared for natural hazards and to better respond in case a disaster strikes, thus addressing the short-term perspective, spatial planning serves long-term planning goals and can therefore implement long-term prevention measures. A purposefully applied risk mitigation strategy requires coordination of short-term and long-term mitigation measures and thus an effective coordination of emergency management and spatial planning. Several actors are involved in risk management and should consequently be linked throughout the whole risk management cycle. However, these actors, partly because of a historically fragmented administrative system, are hardly connected to each other, with spatial planning only having a negligible role compared to other actors1, a problem to which Young (2002) referred to as the "problem of interplay". In contrast, information transfer and decision-taking happen at the same time and are not coordinated among different actors. This applies to the prevention and preparedness phase as well as to the recovery phase, which basically constitutes the prevention phase for the next disaster2. Since investments in both risk prevention and emergency preparedness and response are considered necessary, a better coordination of the two approaches is required. In this regard, Decision Support Systems (DSS) can be useful in order to provide support in the decision-making aspect of risk management. The research work currently undertaken examines the problem of interplay in the four case study areas of the Marie Curie ITN, CHANGES3. The link between different risk management actors will be explored

  1. Abrupt Climatic Change during the Latest Maastrichtian: Establishing Robust Temporal Links with the Onset of Deccan Volcanism and K/Pg Mass Extinction

    A transient period of climate change, characterized by a global warming of 2.5-5°C followed by a cooling to pre-excursion conditions, occurred during the last 300 kyr of the Maastrichtian ( 66.34-66.02 Ma). This instability may have played a role in destabilizing marine and terrestrial ecosystems, priming the system for abrupt extinction at the K-Pg boundary, likely triggered by a large bolide impact. This pre-K-Pg warming event has often been linked to the main phase of Deccan Trap volcanism, however large uncertainties associated with radio-isotopic dating methods of basalts, along with low sedimentation rates and hiatuses in many studied sedimentary sequences, have long hampered a definitive correlation. To complement recent advances in dating of the traps, we have generated the first complete and highest resolution (2.5-4 kyr) benthic stable δ13C and δ18O record for the final million years of the Maastrichtian using the epifaunal foraminifera species Nuttallides truempyi from ODP Site 1262, Walvis Ridge, South Atlantic, calibrated to an updated orbitally-tuned age model. We then compare our data to other previously published geochemical data from other sites in the high, middle, and low latitudes. Our data confirms that the onset of the warming event coincides with the onset of the main phase of Deccan volcanism, strongly suggesting a causal link. Furthermore, spectral analysis of our extended late Maastrichtian-Early Eocene record suggests that the onset of the warming event corresponds to a 405-kyr eccentricity minima, in contrast to many transient warming events (hyperthermals) of the Paleogene, suggesting a control by orbital forcing alone is unlikely. A peculiar feature of the event, compared to other hyperthermals, is a muted carbon cycle response during warming, which may be related to the comparatively heavier δ13C signature of volcanogenic CO2 (-7‰), compared to other sources of light carbon invoked to explain Paleogene hyperthermals. The warming

    By representational difference analysis, we previously identified the rat Erc (Expressed in renal carcinoma) gene that was more abundantly expressed in the renal carcinoma tissues of Eker rats than in the rat normal kidney. In this study, we raised antibodies against the amino-terminal portion of the rat Erc, and demonstrated the existence of a approximately 30-kDa secretory form in the supernatant of cultured cells derived from rat renal carcinoma. The enzyme-linked immunosorbent assay (ELISA) system using these antibodies detected high concentrations of this form in the sera of Eker rats bearing renal carcinomas, and in the sera of rats transplanted with mesothelioma cells. Mesothelin, a human homolog of the rat Erc, was recently reported to be a serum marker of malignant mesothelioma. The prognosis of mesothelioma is poor and there is no effective treatment at present. There are several rat model systems of mesothelioma that may be promising tools in the development of an antimesothelioma treatment. We hope our ELISA to detect the soluble form of rat Erc/Mesothelin is useful in the rat model system to exploit the antimesothelioma therapy to be used in human cases.

    Full Text Available Although the DEAD-box RNA helicase family is ubiquitous in eukaryotes, its developmental role remains unelucidated. Here, we report that cooperative action between the Arabidopsis nucleolar protein RH10, an ortholog of human DEAD-box RNA helicase DDX47, and the epigenetic repressor complex of ASYMMETRIC-LEAVES1 (AS1 and AS2 (AS1-AS2 is critical to repress abaxial (ventral genes ETT/ARF3 and ARF4, which leads to adaxial (dorsal development in leaf primordia at shoot apices. Double mutations of rh10-1 and as2 (or as1 synergistically up-regulated the abaxial genes, which generated abaxialized filamentous leaves with loss of the adaxial domain. DDX47 is part of the small subunit processome (SSUP that mediates rRNA biogenesis. In rh10-1 we found various defects in SSUP-related events, such as: accumulation of 35S/33S rRNA precursors; reduction in the 18S/25S ratio; and nucleolar hypertrophy. Double mutants of as2 with mutations of genes that encode other candidate SSUP-related components such as nucleolin and putative rRNA methyltransferase exhibited similar synergistic defects caused by up-regulation of ETT/ARF3 and ARF4. These results suggest a tight link between putative SSUP and AS1-AS2 in repression of the abaxial-determining genes for cell fate decisions for adaxial development.

    2018-06-01

    We present a multidimensional asymptotic preserving scheme for the approximation of a mixture of compressible flows. Fluids are modelled by two Euler systems of equations coupled with a friction term. The asymptotic preserving property is mandatory for this kind of model, to derive a scheme that behaves well in all regimes (i.e. whatever the friction parameter value is). The method we propose is defined in ALE coordinates, using a Lagrange plus remap approach. This imposes a multidimensional definition and analysis of the scheme.

    Over the past 13 years, ANDRITZ Hydro has developed an in-house tool based on the SPH-ALE method for applications in flow simulations in hydraulic turbines. The initial motivation is related to the challenging simulation of free surface flows in Pelton turbines, where highly dynamic water jets interact with rotating buckets, creating thin water jets traveling inside the housing and possibly causing disturbances on the runner. The present paper proposes an overview of industrial applications allowed by the developed tool, including design evaluation of Pelton runners and casings, transient operation of Pelton units and free surface flows in hydraulic structures.

    Several studies reported that hypnosis can modulate pain perception and tolerance by affecting cortical and subcortical activity in brain regions involved in these processes. We conducted an Activation Likelihood Estimation (ALE) meta-analysis on functional neuroimaging studies of pain perception under hypnosis to identify brain activation-deactivation patterns occurring during hypnotic suggestions aiming at pain reduction, including hypnotic analgesic, pleasant, or depersonalization suggestions (HASs). We searched the PubMed, Embase and PsycInfo databases; we included papers published in peer-reviewed journals dealing with functional neuroimaging and hypnosis-modulated pain perception. The ALE meta-analysis encompassed data from 75 healthy volunteers reported in 8 functional neuroimaging studies. HASs during experimentally-induced pain compared to control conditions correlated with significant activations of the right anterior cingulate cortex (Brodmann's Area [BA] 32), left superior frontal gyrus (BA 6), and right insula, and deactivation of right midline nuclei of the thalamus. HASs during experimental pain impact both cortical and subcortical brain activity. The anterior cingulate, left superior frontal, and right insular cortices activation increases could induce a thalamic deactivation (top-down inhibition), which may correlate with reductions in pain intensity.

    2012-03-01

    A meta-analysis was performed independently to view the changes in gray matter (GM) on patients with Bipolar disorder (BP). The meta-analysis was conducted on a Talairach Space using GingerALE to determine the voxels and their permutation. In order to achieve the data acquisition, published experiments and similar research studies were uploaded onto the online Voxel-Based Morphometry database (VBM). By doing so, coordinates of activation locations were extracted from Bipolar disorder related journals utilizing Sleuth. Once the coordinates of given experiments were selected and imported to GingerALE, a Gaussian was performed on all foci points to create the concentration points of GM on BP patients. The results included volume reductions and variations of GM between Normal Healthy controls and Patients with Bipolar disorder. A significant amount of GM clusters were obtained in Normal Healthy controls over BP patients on the right precentral gyrus, right anterior cingulate, and the left inferior frontal gyrus. In future research, more published journals could be uploaded onto the database and another VBM meta-analysis could be performed including more activation coordinates or a variation of age groups.

    MRI/fMRI has already proven itself as a valuable tool in the diagnosis and treatment of many illnesses of the brain, including cognitive problems. By exploiting the differences in magnetic susceptibility between oxygenated and deoxygenated hemoglobin, fMRI can measure blood flow in various regions of interest within the brain. This can determine the level of brain activity in relation to motor or cognitive functions and provide a metric for tissue damage or illness symptoms. Structural imaging techniques have shown lesions or deficiencies in tissue volumes in schizophrenics corresponding to areas primarily in the frontal and temporal lobes. These areas are currently known to be involved in working memory and attention, which many schizophrenics have trouble with. The ALE (Activation Likelihood Estimation) Meta-Analysis is able to statistically determine the significance of brain area activations based on the post-hoc combination of multiple studies. This process is useful for giving a general model of brain function in relation to a particular task designed to engage the affected areas (such as working memory for the n-back task). The advantages of the ALE Meta-Analysis include elimination of single subject anomalies, elimination of false/extremely weak activations, and verification of function/location hypotheses.

New formulations have been developed for FSI applications using ALE (Arbitrary Lagrangian Eulerian and mesh free methods as SPH method, (Smooth Particle Hydrodynamic. In defence industry, engineers have been developing protection systems for many years to reduce the vulnerability of light armoured vehicles (LAV against mine blast using classical Lagrangian FEM methods. To improve simulations and assist in the development of these protections, experimental tests, and new numerical techniques are performed. To carry out these numerical calculations, initial conditions such as the loading prescribed by a mine on a structure need to be simulated adequately. The effects of blast on structures depend often on how these initial conditions are estimated and applied. In this report, two methods were used to simulate a mine blast: the classical Lagrangian and the ALE formulations. The comparative study was done for a simple and a more complex target. Particle methods as SPH method can also be used for soil structure interaction.

    Imagery is a widely spread technique in the sport sciences that entails the mental rehearsal of a given situation to improve an athlete's learning, performance and motivation. Two modalities of imagery are reported to tap into distinct brain structures, but sharing common components: kinesthetic and visual imagery. This study aimed to investigate the neural basis of those types of imagery with Activation Likelihood Estimation algorithm to perform a meta - analysis. A systematic search was used to retrieve only experimental studies with athletes or sportspersons. Altogether, nine studies were selected and an ALE meta - analysis was performed. Results indicated significant activation of the premotor, somatosensory cortex, supplementary motor areas, inferior and superior parietal lobule, caudate, cingulate and cerebellum in both imagery tasks. It was concluded that visual and kinesthetic imagery share similar neural networks which suggests that combined interventions are beneficial to athletes whereas separate use of those two modalities of imagery may seem less efficient from a neuropsychological approach.

  20. ALE finite volume method for free-surface Bingham plastic fluids with general curvilinear coordinates

    Nagai, Katsuaki; Ushijima, Satoru

    2010-01-01

    A numerical prediction method has been proposed to predict Bingham plastic fluids with free-surface in a two-dimensional container.

    A numerical prediction method has been proposed to predict Bingham plastic fluids with free-surface in a two-dimensional container. Since the linear relationships between stress tensors and strain rate tensors are not assumed for non-Newtonian fluids, the liquid motions are described with Cauchy momentum equations rather than Navier-Stokes equations. The profile of a liquid surface is represented with the two-dimensional curvilinear coordinates which are represented in each computational step on the basis of the arbitrary Lagrangian-Eulerian (ALE) method.

La compresión de estas señales permite disminuir el volumen de datos adquiridos, facilitando su manipulación.   La epilepsia es una de las más comunes de esas enfermedades y las señales que registran este tipo de anomalía difieren algo de las señales electroencefalográficas comunes. En este trabajo se analiza el comportamiento de la compresión de señales que contienen episodios epilépticos, comparado con otras que no lo contienen. Se establecen un grupo de parámetros de calidad y de compresión para establecer la comparación. Como resultado se obtiene una mejor calidad y una mayor compresión cuando la señal contiene episodios epilépticos. Este resultado se asocia a la sincronización que ocurre en estos casos y la correspondiente contracción de las bandas de frecuencia con mayor contenido de información relevante.

  3. Flocculation in ale brewing strains of Saccharomyces cerevisiae: re-evaluation of the role of cell surface charge and hydrophobicity.

    Flocculation is an eco-friendly process of cell separation, which has been traditionally exploited by the brewing industry. Cell surface charge (CSC), cell surface hydrophobicity (CSH) and the presence of active flocculins, during the growth of two (NCYC 1195 and NCYC 1214) ale brewing flocculent strains, belonging to the NewFlo phenotype, were examined. Ale strains, in exponential phase of growth, were not flocculent and did not present active flocculent lectins on the cell surface; in contrast, the same strains, in stationary phase of growth, were highly flocculent (>98%) and presented a hydrophobicity of approximately three to seven times higher than in exponential phase. No relationship between growth phase, flocculation and CSC was observed. For comparative purposes, a constitutively flocculent strain (S646-1B) and its isogenic non-flocculent strain (S646-8D) were also used. The treatment of ale brewing and S646-1B strains with pronase E originated a loss of flocculation and a strong reduction of CSH; S646-1B pronase E-treated cells displayed a similar CSH as the non-treated S646-8D cells. The treatment of the S646-8D strain with protease did not reduce CSH. In conclusion, the increase of CSH observed at the onset of flocculation of ale strains is a consequence of the presence of flocculins on the yeast cell surface and not the cause of yeast flocculation. CSH and CSC play a minor role in the auto-aggregation of the ale strains since the degree of flocculation is defined, primarily, by the presence of active flocculins on the yeast cell wall.

    Fragmentation is a fundamental process that naturally spans micro to macroscopic scales. Recent advances in algorithms, computer simulations, and hardware enable us to connect the continuum to microstructural regimes in a real simulation through a heterogeneous multiscale mathematical model. We apply this model to the problem of predicting how targets in the NIF chamber dismantle, so that optics and diagnostics can be protected from damage. The mechanics of the initial material fracture depend on the microscopic grain structure. In order to effectively simulate the fragmentation, this process must be modeled at the subgrain level with computationally expensive crystal plasticity models. However, there are not enough computational resources to model the entire NIF target at this microscopic scale. In order to accomplish these calculations, a hierarchical material model (HMM) is being developed. The HMM will allow fine-scale modeling of the initial fragmentation using computationally expensive crystal plasticity, while the elements at the mesoscale can use polycrystal models, and the macroscopic elements use analytical flow stress models. The HMM framework is built upon an adaptive mesh refinement (AMR) capability. We present progress in implementing the HMM in the NIF-ALE-AMR code. Additionally, we present test simulations relevant to NIF targets

    We analyze several new and existing approaches for limiting tensor quantities in the context of deviatoric stress remapping in an ALE numerical simulation of elastic flow. Remapping and limiting of the tensor component-by-component is shown to violate radial symmetry of derived variables such as elastic energy or force. Therefore, we have extended the symmetry-preserving Vector Image Polygon algorithm, originally designed for limiting vector variables. This limiter constrains the vector (in our case a vector of independent tensor components) within the convex hull formed by the vectors from surrounding cells – an equivalent of the discrete maximum principle in scalar variables. We compare this method with a limiter designed specifically for deviatoric stress limiting which aims to constrain the J2 invariant that is proportional to the specific elastic energy and scale the tensor accordingly. We also propose a method which involves remapping and limiting the J2 invariant independently using known scalar techniques. The deviatoric stress tensor is then scaled to match this remapped invariant, which guarantees conservation in terms of elastic energy.

  13. Drawing and writing: An ALE meta-analysis of sensorimotor activations.

    Drawing and writing are the two major means of creating what are referred to as "images", namely visual patterns on flat surfaces. They share many sensorimotor processes related to visual guidance of hand movement, resulting in the formation of visual shapes associated with pictures and words. However, while the human capacity to draw is tens of thousands of years old, the capacity for writing is only a few thousand years old, and widespread literacy is quite recent. In order to compare the neural activations for drawing and writing, we conducted two activation likelihood estimation (ALE) meta-analyses for these two bodies of neuroimaging literature. The results showed strong overlap in the activation profiles, especially in motor areas (motor cortex, frontal eye fields, supplementary motor area, cerebellum, putamen) and several parts of the posterior parietal cortex. A distinction was found in the left posterior parietal cortex, with drawing showing a preference for a ventral region and writing a dorsal region. These results demonstrate that drawing and writing employ the same basic sensorimotor networks but that some differences exist in parietal areas involved in spatial processing.

  14. Dynamic debonding in layered structures: a coupled ALE-cohesive approach

    Directory of Open Access Journals (Sweden)

    Marco Francesco Funari

    2017-07-01

    Full Text Available . A computational formulation able to simulate crack initiation and growth in layered structural systems is proposed. In order to identify the position of the onset interfacial defects and their dynamic debonding mechanisms, a moving mesh strategy, based on Arbitrary Lagrangian-Eulerian (ALE approach, is combined with a cohesive interface methodology, in which weak based moving connections are implemented by using a finite element formulation. The numerical formulation has been implemented by means of separate steps, concerned, at first, to identify the correct position of the crack onset and, subsequently, the growth by changing the computational geometry of the interfaces. In order to verify the accuracy and to validate the proposed methodology, comparisons with experimental and numerical results are developed. In particular, results, in terms of location and speed of the debonding front, obtained by the proposed model, are compared with the ones arising from the literature. Moreover, a parametric study in terms of geometrical characteristics of the layered structure are developed. The investigation reveals the impact of the stiffening of the reinforced strip and of adhesive thickness on the dynamic debonding mechanisms.

    Potential threat of intentional sabotage of spent nuclear fuel storage facilities is of significant importance to national security. Paramount is the study of focused energy attacks on these materials and the potential release of aerosolized hazardous particulates into the environment. Depleted uranium oxide (DUO2) is often chosen as a surrogate material for testing due to the unreasonable cost and safety demands for conducting full-scale tests with real spent nuclear fuel. To account for differences in mechanical response resulting in changes to particle distribution it is necessary to scale the DUO2 results to get a proper measure for spent fuel. This is accomplished with the spent fuel ratio (SFR), the ratio of respirable aerosol mass released due to identical damage conditions between a spent fuel and a surrogate material like depleted uranium oxide (DUO2). A very limited number of full-scale experiments have been carried out to capture this data, and the oft-questioned validity of the results typically leads to overly-conservative risk estimates. In the present work, the ALE3D hydrocode is used to simulate DUO2 and spent nuclear fuel pellets impacted by metal jets. The results demonstrate an alternative approach to estimate the respirable release fraction of fragmented nuclear fuel.

    The Neutralized Drift Compression Experiment II (NDCX II) is an induction accelerator planned for initial commissioning in 2012. The final design calls for a 3 MeV, Li+ ion beam, delivered in a bunch with characteristic pulse duration of 1 ns, and transverse dimension of order 1 mm. The NDCX II will be used in studies of material in the warm dense matter (WDM) regime, and ion beam/hydrodynamic coupling experiments relevant to heavy ion based inertial fusion energy. We discuss recent efforts to adapt the 3D ALE-AMR code to model WDM experiments on NDCX II. The code, which combines Arbitrary Lagrangian Eulerian (ALE) hydrodynamics with Adaptive Mesh Refinement (AMR), has physics models that include ion deposition, radiation hydrodynamics, thermal diffusion, anisotropic material strength with material time history, and advanced models for fragmentation. Experiments at NDCX-II will explore the process of bubble and droplet formation (two-phase expansion) of superheated metal solids using ion beams. Experiments at higher temperatures will explore equation of state and heavy ion fusion beam-to-target energy coupling efficiency. Ion beams allow precise control of local beam energy deposition providing uniform volumetric heating on a timescale shorter than that of hydrodynamic expansion. The ALE-AMR code does not have any export control restrictions and is currently running at the National Energy Research Scientific Computing Center (NERSC) at LBNL and has been shown to scale well to thousands of CPUs. New surface tension models that are being implemented and applied to WDM experiments. Some of the approaches use a diffuse interface surface tension model that is based on the advective Cahn-Hilliard equations, which allows for droplet breakup in divergent velocity fields without the need for imposed perturbations. Other methods require seeding or other methods for droplet breakup. We also briefly discuss the effects of the move to exascale computing and related

    A numerical study of the equilibrium and stability properties of the Scyllac experiment at Los Alamos is described. The formulation of the numerical method, which is an extension of the ICED-ALE method to magnetohydrodynamic flow in three dimensions, is given. The properties of the method are discussed, including low computational diffusion, local conservation, and implicit formulation in the time variable. Also discussed are the problems encountered in applying boundary conditions and computing equilibria. The results of numerical computations of equilibria indicate that the helical field amplitudes must be doubled from their design values to produce equilibrium in the Scyllac experiment. This is consistent with other theoretical and experimental results

  3. Soil Sampling to Demonstrate Compliance with Department of Energy Radiological Clearance Requirements for the ALE Unit of the Hanford Reach National Monument

    2007-04-01

    The Hanford Reach National Monument consists of several units, one of which is the Fitzner/Eberhardt Arid Lands Ecology Reserve (ALE) Unit. This unit is approximately 311 km2 of shrub-steppe habitat located to the south and west of Highway 240. To fulfill internal U. S. Department of Energy (DOE) requirements prior to any radiological clearance of land, DOE must evaluate the potential for residual radioactive contamination on this land and determine compliance with the requirements of DOE Order 5400.5. Historical soil monitoring conducted on ALE indicated soil concentrations of radionuclides were well below the Authorized Limits. However, the historical sampling was done at a limited number of sampling locations. Therefore, additional soil sampling was conducted to determine if the concentrations of radionuclides in soil on the ALE Unit were below the Authorized Limits. This report contains the results of 50 additional soil samples. The 50 soil samples collected from the ALE Unit all had concentrations of radionuclides far below the Authorized Limits. The average concentrations for all detectable radionuclides were less than the estimated Hanford Site background. Furthermore, the maximum observed soil concentrations for the radionuclides included in the Authorized Limits would result in a potential annual dose of 0.14 mrem assuming the most probable use scenario, a recreational visitor. This potential dose is well below the DOE 100-mrem per year dose limit for a member of the public. Spatial analysis of the results indicated no observable statistically significant differences between radionuclide concentrations across the ALE Unit. Furthermore, the results of the biota dose assessment screen, which used the ResRad Biota code, indicated that the concentrations of radionuclides in ALE Unit soil pose no significant health risk to biota.

The NDCX II will be used in studies of material in the warm dense matter (WDM) regime, and ion beam/hydrodynamic coupling experiments relevant to heavy ion based inertial fusion energy. We discuss recent efforts to adapt the 3D ALE-AMR code to model WDM experiments on NDCX II. The code, which combines Arbitrary Lagrangian Eulerian (ALE) hydrodynamics with Adaptive Mesh Refinement (AMR), has physics models that include ion deposition, radiation hydrodynamics, thermal diffusion, anisotropic material strength with material time history, and advanced models for fragmentation. Experiments at NDCX-II will explore the process of bubble and droplet formation (two-phase expansion) of superheated metal solids using ion beams. Experiments at higher temperatures will explore equation of state and heavy ion fusion beam-to-target energy coupling efficiency. Ion beams allow precise control of local beam energy deposition providing uniform volumetric heating on a timescale shorter than that of hydrodynamic expansion. We also briefly discuss the effects of the move to exascale computing and related computational changes on general modeling codes in fusion. (authors)

    This paper considers the problems of proving the causal link between a nuclear incident and bodily injury when the latter is a non-stochastic effect or a stochastic effect of ionizing radiation and the author suggests that a solution should be sought in presumption. In the absence of such a solution, inconsistencies with the present tendency to raise coverage amounts might be misunderstood by public opinion if an incident were to occur. To conclude, the author suggests that proof of the causal link should act as a trigger for transfers of financial charges between the different categories of persons. (NEA) [fr

    In 1995, the Spanish-moroccan Mixed Committee for the Gibraltar Strait Fixed Link selected the excavated tunnel solution, as preferred to the suspension bridge one. This was based on detailed scientific and technical studies. Nonetheless, further geology studies on the tunnel layout have detected sections of difficult excavation, which would entail increases in the length, the term of execution and the cost of the tunnel. Taking this into account, and due to the important technology development in bridge construction that has taken place over the last 20 years, the paper presents a state-of-the-art of the most advanced structural materials (high performance concrete, ultra-high performance concrete, suspension cables, structural steel, reinforcing and prestressing steel, stainless steel) available for an eventual reconsideration of the suspension bridge solution for the Gibraltar Strait Fixed Link.

    The neural systems for phonological processing of written language have been well identified now, while models based on these neural systems are different for different language systems or age groups. Although each of such models is mostly concordant across different experiments, the results are sensitive to the experiment design and intersubject variability. Activation likelihood estimation (ALE) meta-analysis can quantitatively synthesize the data from multiple studies and minimize the interstudy or intersubject differences. In this study, we performed two ALE meta-analysis experiments: one was to examine the neural activation patterns of the phonological processing of two different types of written languages and the other was to examine the development characteristics of such neural activation patterns based on both alphabetic language and logographic language data. The results of our first meta-analysis experiment were consistent with the meta-analysis which was based on the studies published before 2005. And there were new findings in our second meta-analysis experiment, where both adults and children groups showed great activation in the left frontal lobe, the left superior/middle temporal gyrus, and the bilateral middle/superior occipital gyrus. However, the activation of the left middle/inferior frontal gyrus was found increase with the development, and the activation was found decrease in the following areas: the right claustrum and inferior frontal gyrus, the left inferior/medial frontal gyrus, the left middle/superior temporal gyrus, the right cerebellum, and the bilateral fusiform gyrus. It seems that adults involve more phonological areas, whereas children involve more orthographic areas and semantic areas. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available Resumen: En este trabajo de investigación se aplican métodos adaptables en el diseño de algoritmos computacionales, dichos algoritmos emplean redes neuronales y series de wavelets para construir “neuroaproximadores” wavenets. Se muestra cómo las wavenets pueden combinarse con los métodos autosintonizables para obtener el seguimiento de señles complejas que están en función del tiempo. Los algoritmos obtenidos se aplican en la aproximación de señales que representan funciones algebraicas y funciones aleatorias, así como en una señal médica deun ECG. Se muestran los resultados en simulación numérica de dos arquitecturas de neuroaproximadores wavenets: el primero está basado en una wavenet, con el cual se aproximan las señales bajo estudio donde los parámetros de la red neuronal son ajustados en línea; el otro esquema emplea un filtro IIR a la salida de la red wavenet para discriminar las contribuciones de aquellas neuronas que tienen menos peso en la aproximación de la señal, lo que ayuda a reducir el tiempo de convergencia a un error mínimo deseado. Abstract: In this paper adaptable methods for computational algorithms are presented. These algorithms use neural networks and wavelet series to build neuro wavenets approximators. The algorithms obtained are applied to the approximation of signals that represent algebraic functions and random functions, as well as a medical EKG signal. It shows how wavenets can be combined with auto-tuning methods for tracking complex signals that are a function of time. Results are shown in numerical simulation of two architectures of neural approximators wavenets: the first is based on a wavenet with which they approach the signals under study where the parameters of the neural network are adjusted online, the other neuro approximator scheme uses an IIR filter to the output of wavenet, which serves to filter the out- put, in this way

    Full Text Available Morphometric characterization is an important element in the study of dynamic cellular behavior in plant responses to biotic and abiotic stimuli. The aim of study was to determine the morphometric parameters of meiocytes and pollen grains in different phases of microsporogenesis in fertile and induced androsterility sunflower plants. Thus, the comparative morphometric analysis revealed the gametocidal effect of gibberellin that is manifested as abnormal changes in shape and volume of cells. These modifications lead to deficiencies in the integrity/rigidity and, respectively, in the functionality of the cell wall, as well as in the physical properties of the protoplasm. The low values of morphometric parameters were also correlated with the degree of sterility of pollen grains. Rezumat. Caracterizarea morfometrică este un element important în studiul proceselor celulare dinamice ca răspuns la stimulii biotici şi abiotici. Scopul studiului constă în determinarea parametrilor morfometrici ai meiocitelor şi grăuncioarelor de polen în diferite faze ale microsporogenezei la plantele de floarea-soarelui fertile şi cu androsterilitate indusă. Astfel, analiza morfometrică comparativă a relevat efectul gametocid al giberelinei exprimat prin schimbările anormale ale formei şi volumului celulelor. Aceste modificări induc deficienţe atât în integritatea/rigiditatea şi, respectiv, în funcţionalitatea peretelui celular, cât şi în proprietăţile fizice ale protoplasmei. De asemenea, valorile scăzute ale parametrilor morfometrici au fost corelate cu gradul de sterilitate al grăuncioarelor de polen.

    Full Text Available Teorii și practice ale integrării europene [Theories and Practices of European Integration] is a genuine contribution to understanding how the European Union’s particular character has been adjusted in more than half of century of institutional growth and development. Professor Ivan`s key argument for this book is that the European Union has been shaped as a functional project taking into consideration the diverse heritage and traditions of its Member States. The opening chapter of this book focuses on the particularities of international relations discipline after the Second World War in order to introduce the theme of European Integration Process. This chapter must be analysed in a series of contributions dedicated to the European Integration process and to the theories that made this integration possible because professor Ivan has previously published books such as: Statele Unite ale Europei [The United States of Europe], Sub zodia Statelor Unite ale Europei [Under the Sign of the United States of Europe], in which he debates the origins of the European construction and brings forward arguments to support the importance of each theoretical and functional pillar of this “Common European Project”.

In an attempt to better understand the essence of some of these popular and religious social components, this paper aims to briefly present the most relevant biographical notes about Rafael D. Crisanto Alesón Alesón as a first approach to his life. Alesón was a character who lived between those two centuries which meant the emergence of the Enlightenment firstly and liberalism thereafter, that would eventually overthrow the Old Regime monarchy. A man of the Church, well educated, who enjoyed a comfortable economic status that gave him a good education and high social consideration from his neighbors. These pages seek to define this religious figure who, from a local level and a humble exercise of his religious ministry, helped to spread the message of the Catholic faith at a time of great stress and generalized crisis in Spain.

    2015-01-01

    The moduli space of instantons on an ALE space is studied using the moduli space of $\\mathcal{N}=4$ field theories in three dimensions. For instantons in a simple gauge group $G$ on $\\mathbb{C}^2/\\mathbb{Z}_n$, the Hilbert series of such an instanton moduli space is computed from the Coulomb branch of the quiver given by the affine Dynkin diagram of $G$ with flavour nodes of unitary groups attached to various nodes of the Dynkin diagram. We provide a simple prescription to determine the ranks and the positions of these flavour nodes from the order of the orbifold $n$ and from the residual subgroup of $G$ that is left unbroken by the monodromy of the gauge field at infinity. For $G$ a simply laced group of type $A$, $D$ or $E$, the Higgs branch of such a quiver describes the moduli space of instantons in projective unitary group $PU(n) \\cong U(n)/U(1)$ on orbifold $\\mathbb{C}^2/\\hat{G}$, where $\\hat{G}$ is the discrete group that is in McKay correspondence to $G$. Moreover, we present the quiver whose Coulomb ...

    1980-05-01

    The analyses of 18 volcanic gas samples collected over a two-hour period at 1075/sup 0/C from Erta' Ale lava lake in December 1971 and of 18 samples taken over a half-hour period at 1125 to 1135/sup 0/C in 1974 display moderately to intensely variable compositions. These variations result from imposed modifications caused by (1) atmospheric contamination and oxidation, (2) condensation and re-evaporation of water during collection, (3) analytical errors, and (4) chemical reactions between the erupted gases and a steel lead-in tube. Detailed examinations of the analyses indicate the erupted gases were at chemical equilibrium before collection. This condition was partially destroyed by the imposed modifications. High-temperature reaction equilibria were more completely preserved in the 1974 samples. Numerical procedures based on thermodynamic calculations have been used to restore each analysis to a composition representative of the erupted gases. These procedures have also been used to restore the anhydrous mean compositions reported for two series of collections taken at the lava lake in January 1973.

    In 1912, Louis-Camille Maillard described a reaction between amino acids and reducing sugars that produced a discolored (brown) reaction mixture in the presence of heat [1]. This complex network of reactions between reducing sugars and free amine groups on amino acids or proteins came to be known as the Maillard reaction and was the domain of food chemists for the next 50 years. Work in the 1960s began a very exciting era in the field. A few years earlier, several groups [2-5] reported on the heterogeneity of normal human adult hemoglobin (HbA) as determined chromatographically, and Allen et al were the first to use cation-exchange chromatography to separate a previously observed fast moving component (HbAI) into three fractions that they termed AIa, AIb, and AIc. An increase in the fast moving HbAI of four diabetic patients was subsequently reported by Huisman and Dozy in 1962 [6], and the link between diabetes and increased HbAI was later strengthened by Rahbar’s observation of increased HbAI – the majority of which is HbAIc – in 47 cases of diabetes [7]. Bookchin and Gallop determined that HbAIc consisted of a hexose bound to both β-chains [8], and Bunn and colleagues subsequently proposed that glucose binds to the N-terminal amine groups of the β-chain valine residues in the form of a Schiff base, which then rearranges to form an Amadori compound [9]. Thus, while Maillard chemistry was known to occur during the heating and processing of food, the identification of Amadori-modified hemoglobin proved that it also occurred in vivo (after all, as John Baynes likes to point out, humans are essentially low temperature ovens with long cooking cycles!).

    2016-06-01

    Brewing yeasts are classified into two species-Saccharomyces pastorianus and Saccharomyces cerevisiae. Most of the brewing yeast strains are natural interspecies hybrids typically polyploids and their identification is thus often difficult giving heterogenous results according to the method used. We performed genetic characterization of a set of the brewing yeast strains coming from several yeast culture collections by combination of various DNA-based techniques. The aim of this study was to select a method for species-specific identification of yeast and discrimination of yeast strains according to their technological classification. A group of 40 yeast strains were characterized using PCR-RFLP analysis of ITS-5·8S, NTS, HIS4 and COX2 genes, multiplex PCR, RAPD-PCR of genomic DNA, mtDNA-RFLP and electrophoretic karyotyping. Reliable differentiation of yeast to the species level was achieved by PCR-RFLP of HIS4 gene. Numerical analysis of the obtained RAPD-fingerprints and karyotype revealed species-specific clustering corresponding with the technological classification of the strains. Taxonomic position and partial hybrid nature of strains were verified by multiplex PCR. Differentiation among species using the PCR-RFLP of ITS-5·8S and NTS region was shown to be unreliable. Karyotyping and RFLP of mitochondrial DNA evinced small inaccuracies in strain categorization. PCR-RFLP of HIS4 gene and RAPD-PCR of genomic DNA are reliable and suitable methods for fast identification of yeast strains. RAPD-PCR with primer 21 is a fast and reliable method applicable for differentiation of brewing yeasts with only 35% similarity of fingerprint profile between the two main technological groups (ale and lager) of brewing strains. It was proved that PCR-RFLP method of HIS4 gene enables precise discrimination among three technologically important Saccharomyces species. Differentiation of brewing yeast to the strain level can be achieved using the RAPD-PCR technique. © 2016 The

În pofida evoluţiilor înregistrate la nivel instituţional în Uniunea Europeană în ultimul deceniu şi jumătate, autorităţile de supraveghere naţionale au continuat să fie privite ca principalii actori care sunt responsabili de supravegherea prudenţială a instituţiilor financiare. Subiectul este cu atât mai captivant cu cât regle­men­tările europene în materie nu vin să stabilească o abordare unitară pentru toate statele membre, ceea ce face ca, la data analizei, să întâlnim o diversitate de modalităţi de organizare a activităţilor de supraveghere prudenţială.MODELS OF MACROPRUDENTIAL SUPERVISION FRAMEWORKThe issue of financial markets supervision in general and banking in particular is still a very topical issue. Taking into account the complexity and the variety of the issues that may be the object of this topic, the present paper is not having a comprehensive approach, as we would not succeed, but is mainly an analysis of the role of national supervising authorities. Despite the achievements registered at the institutional level in the EU during the last decade, the national supervisory authorities continue to be seen as the main actors responsible for the prudential supervision of financial institutions. The subject is even more interesting as the European regulations are not aimed at establishing a uniform approach for all Member States, which made us meet, during our analysis, a variety of ways of organizing the activities of prudential supervision.

    Full Text Available Introduction : Cette étude vise à comparer le contenu nutritionnel et les bienfaits pour la santé des céréales pour déjeuner destinées aux enfants et celles non destinées aux enfants et à évaluer la prédominance du sucre ajouté dans ces produits. Méthodologie : Nous avons recueilli des données sur le contenu nutritionnel de 262 céréales pour déjeuner vendues dans les cinq principales chaînes d’alimentation à Ottawa (Ontario et à Gatineau (Québec. Pour chaque céréale, nous avons pris en note les cinq premiers ingrédients et la quantité de sucres ajoutés indiqués sur la liste des ingrédients. Les diverses marques de céréales ont été ensuite classées en deux catégories, soit « plus saines » ou « moins saines », à l’aide du modèle de profil nutritionnel du Royaume-Uni. Nous avons évalué chaque céréale en fonction de divers critères afin de déterminer si elle était destinée ou non aux enfants. Des comparaisons statistiques ont été établies entre les céréales destinées aux enfants et les autres. Résultats : Sur l'ensemble des céréales pour déjeuner, 19,8 % étaient destinées aux enfants et contenaient beaucoup moins de gras et de gras saturés. Ces céréales avaient une teneur en sodium et en sucre significativement plus élevée et une teneur en fibres et en protéines plus faible, et elles étaient trois fois plus susceptibles d’être classées comme « moins saines » par rapport aux céréales non destinées aux enfants. Aucune des céréales destinées aux enfants n’était sans sucre et, pour 75 % d’entre elles, le sucre occupait le deuxième rang dans la liste des ingrédients. Six entreprises de céréales pour déjeuner possédaient une gamme de produits destinés aux enfants composée entièrement de céréales « moins saines ». Conclusion : Il est nécessaire d’adopter un règlement qui limite le marketing alimentaire ciblant les enfants et les jeunes de moins de 17

    The brain network governing meditation has been studied using a variety of meditation practices and techniques practices eliciting different cognitive processes (e.g., silence, attention to own body, sense of joy, mantras, etc.). It is very possible that different practices of meditation are subserved by largely, if not entirely, disparate brain networks. This assumption was tested by conducting an activation likelihood estimation (ALE) meta-analysis of meditation neuroimaging studies, which assessed 150 activation foci from 24 experiments. Different ALE meta-analyses were carried out. One involved the subsets of studies involving meditation induced through exercising focused attention (FA). The network included clusters bilaterally in the medial gyrus, the left superior parietal lobe, the left insula and the right supramarginal gyrus (SMG). A second analysis addressed the studies involving meditation states induced by chanting or by repetition of words or phrases, known as “mantra.” This type of practice elicited a cluster of activity in the right SMG, the SMA bilaterally and the left postcentral gyrus. Furthermore, the last analyses addressed the effect of meditation experience (i.e., short- vs. long-term meditators). We found that frontal activation was present for short-term, as compared with long-term experience meditators, confirming that experts are better enabled to sustain attentional focus, rather recruiting the right SMG and concentrating on aspects involving disembodiment.

    Full Text Available The overall objective of this paper is to analyze the effect of origin on the physical-mechanical Pinus tropicalis Morelet wood, with a view to providing the information necessary for their rational use properties. Five provenances were selected in the experimental plots at the Experimental Station of Viñales, where 10 trees were randomly selected to analyze the dendrometer following variables: diameter at 1.30 total height, crown diameter and crown height. In turn, at the height of 1.30 m a log of 50 cm in length for the study Densities, Total shrinkage in volume, radial contraction, Longitudinal, tangential and compression is obtained. The results obtained state that the origin is not a variable that has a marked influence on the physical - mechanical properties analyzed. Diameter 1.30 and crown diameter dendrometric variables are best levels of correlation present in relation to the properties of the wood examined. Considering the results obtained provenances La Jagua and Viñales must be very careful during drying and commissioning since they have a higher coefficient of anisotropy.

    Full Text Available Advanced glycation (AGEs and lipoxidation (ALEs products are formed through specific condensation reactions between nucleophiles (amino groups of free amino acids or their residues in peptides, aminophospholipids or proteins and electrophiles (carbonyls of reducing sugars, oxidized lipids or others generating well-defined sets of covalent adducts. The ε-amino group of the lysine is the most reactive precursor in proteins and the primary target of carbohydrate attacks. AGEs/ALEs accumulation has consequences in the development of vascular, renal, neural and ocular complications, as well as in the triggering of inflammatory and neurodegenerative diseases. Therefore, AGEs/ALEs detection, quantification and, in some cases, the assessment of the extent of glycation in biomolecules of different matrices represent a factor of primary interest for science. Reliable analytical methods are thus required. Together with basic concepts, this review presents the main advances, challenges and prospects of research involving AGEs and ALEs in biological and food systems, exploring practical strategies to ensure greater reliability in the analysis of these compounds in different matrices.

The proposals arise from a full review carried out in 1989 and include points raised by the Select Committee on the Trident programme. Studies of productivity, pay and conditions, information systems and long term manufacturing strategy have been started to enable recommendations of the reorganisation of the establishments to be made. The details of the Bill were debated for just over two hours. The debate is reported verbatim. The main issues were over the principle of contractorisation, possible staff redundancies, conditions of employment, safety and security. The proposal that the Bill be read a second time was carried.

    Full Text Available En este artículo se presenta el desarrollo de un filtro para la reducción de la interferencia de línea de potencia en señales electrocardiográficas (ECG, basado en estimación dual de parámetros y de estado, empleando la filtración Kalman, en el cual se consideran modelos independientes entre la interferencia de línea de potencia y la señal ECG. Ambos modelos son combinados para simular la señal ECG medida sobre la que se realiza la estimación de estado para separar la señal de la interferencia. El algoritmo propuesto es sintonizado y comparado en un conjunto de pruebas realizadas sobre la base de datos QT de electrocardiografía. Inicialmente se hacen pruebas de sintonización del algoritmo para el rastreo de la señal ECG limpia, cuyos resultados son utilizados después para las pruebas de filtrado. Luego se llevan a cabo pruebas exhaustivas sobre la base de datos QT en la filtración de interferencia de línea de potencia, la cual ha sido introducida artificialmente en los registros, para una relación de señal a ruido (SNR dada, obteniendo así curvas del desempeño del algoritmo, que permiten a su vez comparar con el desempeño de otros algoritmos de filtración, a saber, un filtro notch recursivo de respuesta infinita al impulso (IIR y un filtro de Kalman, basado en un modelo más simple para la señal ECG. Como resultado, se demuestra que el algoritmo de filtrado obtenido es robusto a los cambios de amplitud de la interferencia; además, conserva sus propiedades para los diferentes tipos de morfologías de señales ECG normales y patológicas.

    Les malformations anorectales chez l'adulte sont des anomalies congénitales rares du tube digestif qui prédominent chez le sexe féminin. Notre étude porte sur deux observations de malformation anorectale basses vues et traitées au stade adulte par les 2 équipes (plasticiens et viscéralistes) à l'Hôpital Avicenne à Rabat. Il s'agit d'un homme de 24 ans avec une dyschésie anale l'autre cas est une femme de 18 ans avec une malformation anovulvaire Les caractéristiques cliniques combinées avec les imageries radiologiques (lavement baryté, et la manométrie anorectale) ont confirmé qu'il s'agit d'une malfomation anorectale basse. Les deux cas sont corrigés par une reconstruction sphinctérienne, réimplantation anale avec anoplastie périnéale. Les suites opératoires étaient simples, pas de souffrance cutanée ou nécrose, avec changement de pansement gras chaque jour. Le résultat fonctionnel (la continence) était favorable pour les 2 patients. La présentation des MAR à l’âge adulte est rare, d’étiologie mal connu, elles apparaissent selon le mode sporadique. Les caractéristiques cliniques, couplées à l'imagerie (lavement baryté, IRM pelvienne), l'endoscopie et la manométrie anorectale, permettent de confirmer le diagnostic et classer ces anomalies en 3 types: basses, intermédiaires, et hautes. Les formes basses sont traités d'emblée par une réimplantation anale et anoplastie périnéale simple tels nos deux cas, elles peuvent être traités dans certains cas par un abaissement anorectale associé à une plastie V-Y permettant ainsi un emplacement anatomique correct de l'anus; alors que les formes hautes ou intermédiaires relèvent d'une chirurgie complexe avec souvent une dérivation digestive transitoire. Contrairement aux autres formes, Les formes basses ont un pronostic fonctionnel favorable. PMID:25667689

  2. Establishing Substantial Equivalence: Transcriptomics

    Science.gov (United States)

    Baudo, María Marcela; Powers, Stephen J.; Mitchell, Rowan A. C.; Shewry, Peter R.

    Regulatory authorities in Western Europe require transgenic crops to be substantially equivalent to conventionally bred forms if they are to be approved for commercial production. One way to establish substantial equivalence is to compare the transcript profiles of developing grain and other tissues of transgenic and conventionally bred lines, in order to identify any unintended effects of the transformation process. We present detailed protocols for transcriptomic comparisons of developing wheat grain and leaf material, and illustrate their use by reference to our own studies of lines transformed to express additional gluten protein genes controlled by their own endosperm-specific promoters. The results show that the transgenes present in these lines (which included those encoding marker genes) did not have any significant unpredicted effects on the expression of endogenous genes and that the transgenic plants were therefore substantially equivalent to the corresponding parental lines.

  4. Causality re-established.

    Science.gov (United States)

    D'Ariano, Giacomo Mauro

    2018-07-13

    Causality has never gained the status of a 'law' or 'principle' in physics. Some recent literature has even popularized the false idea that causality is a notion that should be banned from theory. Such misconception relies on an alleged universality of the reversibility of the laws of physics, based either on the determinism of classical theory, or on the multiverse interpretation of quantum theory, in both cases motivated by mere interpretational requirements for realism of the theory. Here, I will show that a properly defined unambiguous notion of causality is a theorem of quantum theory, which is also a falsifiable proposition of the theory. Such a notion of causality appeared in the literature within the framework of operational probabilistic theories. It is a genuinely theoretical notion, corresponding to establishing a definite partial order among events, in the same way as we do by using the future causal cone on Minkowski space. The notion of causality is logically completely independent of the misidentified concept of 'determinism', and, being a consequence of quantum theory, is ubiquitous in physics. In addition, as classical theory can be regarded as a restriction of quantum theory, causality holds also in the classical case, although the determinism of the theory trivializes it. I then conclude by arguing that causality naturally establishes an arrow of time. This implies that the scenario of the 'block Universe' and the connected 'past hypothesis' are incompatible with causality, and thus with quantum theory: they are both doomed to remain mere interpretations and, as such, are not falsifiable, similar to the hypothesis of 'super-determinism'.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

    This research is about gene distribution of ABO blood type system on the Dengue Hemorrhagic Fever (DHF) patients in the working area of Puskesmas Bonto Bangun, District of Rilau Ale, Bulukumba. This research aimed to determine the blood type which is most affected by DHF using ABO blood type system. In this research, there are 104 samples, 8 of them were attacked by DF and 96 were attacked by DHF. From the 96 patients of DHF, there were 38 patients with A-blood type, 17 patients with B-blood type, 36 patients with O-blood type and 5 patients of AB-blood type. The data were tested using genotype frequency test and the results showed that the percentage of A-homozygous blood type (IAIA) is 0:09%; A heterozygous blood type (IAIo) is 0:36%; B-homozygous blood type (IBIB) is 0.01%; B heterozygous blood type (IB Io) is 0.12%; AB blood type (IAIB) is 0.06% and O blood type (IoIo) is 12:36%. So the biggest frequency of genotype are IAIo (0.36%) and IoIo (0.36%). The results showed that O blood type gene is the most affected by DHF. Then continued by the regression test between blood type and DHF, it is obtained that the correlation value is 1 which indicated that there is a strong relationship.

    Full Text Available Resumen: Uno de los principales retos en el diseño de prótesis de mano es poder establecer un control intuitivo que reduzca el esfuerzo del usuario durante su entrenamiento. Este trabajo presenta un esquema para identificar tareas de motricidad fina de la mano, agrupadas en movimientos de los dedos individuales y gestos para el agarre de objetos el cual se ha validado con sujetos amputados. Se han comparado diferentes métodos de selección de características y clasificadores para el reconocimiento de patrones mioeléctricos, utilizando cuatro electrodos superficiales. Las características de las señales en el dominio del tiempo y la frecuencia se han combinado con métodos no lineales basados en análisis de fractales, mostrando una diferencia significativa en comparación con los métodos expuestos en la literatura para clasificar tareas de fuerza. Los resultados con amputados mostraron una exactitud de hasta 99,4% en los movimientos individuales de los dedos, superior a la obtenida con los gestos de agarre, de hasta 93,3%. El sistema ha obtenido una tasa de acierto promedio de 86,3% utilizando máquinas de soporte vectorial (SVM, seguido muy de cerca por K-vecinos más cercanos (KNN con 83,4%. Sin embargo, KNN ha obtenido un mejor rendimiento global, debido a que es más rápido que SVM, lo que representa una ventaja para aplicaciones en tiempo real. El método aquí propuesto ofrece una mayor funcionalidad en el control de prótesis de mano, lo que mejoraría su aceptación por parte de los amputados.

    Food cues are omnipresent and may enhance overconsumption. In the last two decades the prevalence of childhood obesity has increased dramatically all over the world, largely due to overconsumption. Understanding children's neural responses to food may help to develop better interventions for preventing or reducing overconsumption. We aimed to determine which brain regions are concurrently activated in children/adolescents in response to viewing food pictures, and how these relate to adult findings. Two activation likelihood estimation (ALE) meta-analyses were performed: one with studies in normal weight children/adolescents (aged 8-18, 8 studies, 137 foci) and one with studies in normal weight adults (aged 18-45, 16 studies, 178 foci). A contrast analysis was performed for children/adolescents vs. adults. In children/adolescents, the most concurrent clusters were in the left lateral orbitofrontal cortex (OFC), the bilateral fusiform gyrus, and the right superior parietal lobule. In adults, clusters in similar areas were found. Although the number of studies for a direct statistical comparison between the groups was relatively low, there were indications that children/adolescents may not activate areas important for cognitive control. Overall, the number of studies that contributed to the significant clusters was moderate (6-75%). In summary, the brain areas most consistently activated in children/adolescents by food viewing are part of the appetitive brain network and overlap with those found in adults. However, the age range of the children studied was rather broad. This study offers important recommendations for future research; studies making a direct comparison between adults and children in a sufficiently narrow age range would further elucidate how neural responses to food cues change during development.

    To evaluate marine sediment quality in the Gulf of Cadiz, chemical concentration and toxicity test endpoints from sediments were linked using multivariate analysis. Sediment samples were collected synoptically at seven stations in two littoral ecosystems of the Gulf of Cadiz (five in the Bay of Cadiz and two in the salt marsh of the Barbate River), and subjected to six separate, replicated sediment toxicity tests and comprehensive sediment chemistry analyses. The toxic effects of sediments were tested using three operational sediment phases: whole sediment, using the estuarine amphipod Microdeutopus gryllotalpa (10 d static: survival) and the estuarine clam Ruditapes philippinaru (48 h static: survival) and of the marine fish Sparus aurata (48 h static. Survival); and interstitial water, using populations of the estuarine rotifer Brachionus Plicatilis (7 d static: Population decline) and of the marine bacteria Photobacterium phosphoreum (Microtox ). To evaluate the levels of contamination, the concentrations in the sediments of organic carbon, 14 trace metals (Fe, Mn, Cu, Zn, Pb, Cd, Ag, Hg, As, Sn, V, Ni, Co and Cr) and the surfactant linear alkylbenzenesulphonate (LAS) were measured. The results of the toxicity tests were compared in a dose-response relationship between sites, demonstrating a general agreement between the toxicity values determined by all the tests, except in the case of interstitial water toxicity (principally due to toxic mixtures of trace metals). Data derived from sediment chemistry and bioassays were assembled by multivariate statistical techniques (PCA and factor analysis), showing that the two data types could be represented by only five factors corresponding to five overlapping chemical-biological effect relations. Positive prevalence of these factors in the cases studied was used to establish those ranges in chemical concentrations associated with adverse effects.

    Autism and related disorders are grouped into the category of « Autism Spectrum Disorder » (ASD) in the DSM-5. This appellation reflects the idea of a dimensional representation of autism that combines symptoms and characteristics that vary in severity and intensity. Despite common characteristics, there are varying degrees in intensity and in the onset of symptoms, ranging from a disability that can be very heavy with a total lack of communication and major disorders associated with the existence of a relative autonomy associated, sometimes, with extraordinary intellectual abilities. Parents are faced with several difficult situations, such as sleep disturbances, agitation, shouting, hetero violence, self-harm, learning difficulties, stereotyping, lack of social and emotional reciprocity, inappropriate behavior, etc. They can feel helpless and may experience stress related to these developmental and behavioral difficulties. The heterogeneity of symptoms, the presence of behavioral problems, the lack of reciprocity and autonomy also represent a challenge for practitioners in institutions and teachers at school. The objective of this research is to present the validation of a French translation of the Appraisal of Life Events Scale (ALES-vf) from Ferguson, Matthex and Cox, specifically adapted to the context of ASD. ALES was originally developed to operationalize the three dimensions of perceived stress (threat, loss and challenge) described by Lazarus and Folkman. ALES-vf was initially translated into French and adapted to the situation of parents of children with ASD. It was subsequently administered to 343 parents, 150 paramedical professionals involved with people with ASD, and 155 teachers from an ordinary school environment and from specialized schools, welcoming in their classroom at least one child with ASD. An exploratory factor analysis performed on data from 170 parents highlighted two exploratory models with four and three factors, slightly different

    Full Text Available En la actualidad el campo de la visión computacional, se muestra como una técnica que facilitará las actividades que pasan desapercibidas o no se es capaz de captar por descuido o falta de información. En este sentido son varios los campos que se beneficiarán por el uso de visión para contar con información que facilite operaciones, indique detalles no disponibles a simple vista, etc. En nuestro caso se presenta un prototipo que permite ayudar a un conductor de un vehículo a colocar atención a las señales del tránsito que estén postadas en la vía, pretendiendo asistir al conductor, y por ende evitar infracciones o accidentes. El prototipo desarrollado con técnicas de visión computacional, permite detectar y reconocer las señaléticas presentes en la vía e informar su naturaleza al conductor mediante una señal audible o proyección visual. La investigación se centró principalmente en las fases de detección inicial; con el fin de contar con una heurística rápida, aprovechando la segmentación por color, con sus características de invariabilidad del sistema HSV (Brillo, Saturación, Valor [10], y/o detección inicial por bordes, aprovechando el algoritmo de Chamfer optimizado [1] . Para finalmente detectar y reconocer los símbolos de la señal, utilizando técnicas de transformación distancia y matching jerárquico de Chamfer [1], acondicionadas para este tipo de aplicación. El prototipo en su fase de prueba fue implementado en Matlab, con el propósito inicial de comprobar la efectividad de los métodos empleados. Una vez comprobados se utilizó OpenCV para probar su funcionamiento en tiempo real.Nowdays the computer vision field is shown as a technique that will facilitate those activities that are not noticed or those that have not been caught because of a lack of information.

    Wrist and knee radiographs from children with X-linked hypophosphatemic rickets were analyzed and compared with those from normal children and children with established rickets to assess whether radiographically apparent rickets is a consistent abnormality in X-linked hypophosphatemia. The absence or presence of rickets was correctly identified in 94.8% of wrist and knee films from normal and positive controls. In contrast, patients with X-linked hypophosphatemia exhibited rachitic abnormalities in only 5 of 11 wrist and 13 of 15 knee radiographs. Our data indicate that radiographically detectable rickets is a variable abnormality of X-linked hypophosphatemia and does not provide an unambiguous index for the diagnosis of this disease.

    Wells, James D.; Zhang, Zhengkang; Zhao, Yue

    2017-02-01

    The goal of this article is to initiate a discussion on what it takes to claim ''there is no new physics at the weak scale,'' namely that the Standard Model (SM) is ''isolated.'' The lack of discovery of beyond the SM (BSM) physics suggests that this may be the case. But to truly establish this statement requires proving all ''connected'' BSM theories are false, which presents a significant challenge. We propose a general approach to quantitatively assess the current status and future prospects of establishing the isolated SM (ISM), which we give a reasonable definition of. We consider broad elements of BSM theories, and show many examples where current experimental results are not sufficient to verify the ISM. In some cases, there is a clear roadmap for the future experimental program, which we outline, while in other cases, further efforts - both theoretical and experimental - are needed in order to robustly claim the establishment of the ISM in the absence of new physics discoveries.

    The debate concerns the authorisation of payment of the money required to reorganise the atomic weapons establishment in the United Kingdom provided for in the Atomic Weapons Establishment Bill in progress through Parliament. In the Bill the contractorisation of the establishment is recommended and some sort of Government owned company operated scheme set up. The debate lasted about half an hour and is reported verbatim. The issues raised concerned the actual sums likely to be incurred in the formation of a Company to carry out the designated activities of the Bill. These are connected with the research, development, production or maintenance of nuclear devices and the premises needed. The government spokesman suggested the sums required to support the Bill would not be large and the resolution was agreed to without a vote. (UK)

    Three conventional methods used to establish flaw tolerances are compared with new approaches using fracture mechanics. The conventional methods are those based on (a) non-destructive testing methods; (b) fabrication and quality assurance experience; and (c) service and damage experience. Pre-requisites of fracture mechanics methods are outlined, and summaries given of linear elastic mechanics (LEFM) and elastoplastic fracture mechanics (EPFM). The latter includes discussion of C.O.D.(crack opening displacement), the J-integral and equivalent energy. Proposals are made for establishing flaw tolerances. (U.K.)

    "Linked Data" is a term used in Computer Science to encapsulate a methodology for publishing data and metadata in a structured format so that links may be created and exploited between objects. Berners-Lee (2006) outlines the following four design principles of a Linked Data system: Use Uniform Resource Identifiers (URIs) as names for things. Use HyperText Transfer Protocol (HTTP) URIs so that people can look up those names. When someone looks up a URI, provide useful information, using the standards (Resource Description Framework [RDF] and the RDF query language [SPARQL]). Include links to other URIs so that they can discover more things. In 2010, Berners-Lee revisited his original design plan for Linked Data to encourage data owners along a path to "good Linked Data". This revision involved the creation of a five star rating system for Linked Data outlined below. One star: Available on the web (in any format). Two stars: Available as machine-readable structured data (e.g. An Excel spreadsheet instead of an image scan of a table). Three stars: As two stars plus the use of a non-proprietary format (e.g. Comma Separated Values instead of Excel). Four stars: As three stars plus the use of open standards from the World Wide Web Commission (W3C) (i.e. RDF and SPARQL) to identify things, so that people can point to your data and metadata. Five stars: All the above plus link your data to other people's data to provide context Here we present work building on the SeaDataNet common vocabularies served by the NERC Vocabulary Server, connecting projects such as the Rolling Deck to Repository (R2R) and the Biological and Chemical Oceanography Data Management Office (BCO-DMO) and other vocabularies such as the Marine Metadata Interoperability Ontology Register and Repository and the NASA Global Change Master Directory to create a Linked Ocean Data cloud. Publishing the vocabularies and metadata in standard RDF XML and exposing SPARQL endpoints renders them five-star Linked

    Full Text Available Uno de los problemas comunes que se presentan en las ruedas de los trenes, es la presencia de planos. Éstos generan un impacto suficiente como para afectar el funcionamiento normal del tren. La detección temprana de planos en las ruedas permite realizar las correcciones necesarias (tornear la superficie de la rueda a fin de evitar daños a los componentes del tren que degraden la prestación del servicio a los usuarios. Aunque existen muchos sensores de vibración en el mercado para detectar vibraciones generadas por el paso de un tren, no hay aún una herramienta estándar que permitan detectar la presencia de planos en las ruedas del mismo. Este estudio presenta la selección apropiada de una ventana temporal para utilizar la Transformada de Fourier en Tiempos Cortos (STFT, por sus siglas en inglés en el análisis de señales de vibración, tomadas al pie del carril y generadas al paso de un tren, que permita determinar la presencia de dichos planos. Para ello, en primer lugar se generó, utilizando la herramienta Matlab, una señal que simule la presencia de un plano y que permita conocer como la STFT, implementando diferentes ventanas temporales (Rectangular, Gauss, Hanning y Chebyshev, permite descubrir la presencia del mismo, en el dominio conjunto tiempo-frecuencia. Seguidamente, se aplica la STFT a señales tomadas en campo. Los resultados obtenidos demuestran que la STFT es una herramienta efectiva para detectar planos en la rueda de los trenes, si la función ventana y sus parámetros se seleccionan correctamente al realizar un análisis tiempo-frecuencia.

    1988-01-01

    At the Geneva Summit Meeting in November, 1985, a proposal was made by the Soviet Union to build a next-generation tokamak experiment on a collaborative basis involving the world's four major fusion blocks. In October, 1986, after consulting with Japan and the European Community, the United States responded with a proposal on how to implement such an activity. Ensuing diplomatic and technical discussions resulted in the establishment, under the auspices of the IAEA, of the International Thermonuclear Experimental Reactor Conceptual Design Activities. This tome represents a collection of all documents relating to the establishment of ITER, beginning with the initial meeting of the ITER Quadripartite Initiative Committee in Vienna on 15-16 March, 1987, through the meeting of the Provisional ITER Council, also in Vienna, on 8-9 February, 1988

    Full text: The main objective of the activity of the Establishment for Nuclear Equipment (ZdAJ) in 1999 was to obtain the ISO 9001 certificate. Work on this problem has been successfully completed. The changes introduced in agreement with requirements of ISO in supervising the construction, manufacturing and servicing eliminate possible deficiencies of our products and will pay in the future. Two new important ventures have been undertaken: design of an accelerator with two photon energies and a reconstruction of simulator directed towards better geometrical parameters. The completion of the improvements in accelerator is foreseen for the year 2002. The changes comprise almost all sub-assemblies of the device. The modernized simulator will be installed in the hospital already in the year 2000 - the ameliorations concern mainly the arm of the apparatus, collimator, driving gears and control system. Of course - apart from this, the routine production activity of the Establishment was continued in 1999. (author)

    Status epilepticus is the most severe form of epilepsy, with a high mortality rate and high health care costs. Status epilepticus is divided into four stages: early, established, refractory, and super-refractory. While initial treatment with benzodiazepines has become standard of care for early status epilepticus, treatment after benzodiazepine failure (established status epilepticus (ESE)) is incompletely studied. Effective treatment of ESE is critical as morbidity and mortality increases dramatically the longer convulsive status epilepticus persists. Phenytoin/fosphenytoin, valproic acid, levetiracetam, phenobarbital, and lacosamide are the most frequently prescribed antiseizure medications for treatment of ESE. To date there are no class 1 data to support pharmacologic recommendations of one agent over another. We review each of these medications, their pharmacology, the scientific evidence in support and against each in the available literature, adverse effects and safety profiles, dosing recommendations, and limitations of the available evidence. We also discuss future directions including the established status epilepticus treatment trial (ESETT). Substantial further research is urgently needed to identify these patients (particularly those with non-convulsive status epilepticus), elucidate the most efficacious antiseizure treatment with head-to-head randomized prospective trials, and determine whether this differs for convulsive vs. non-convulsive ESE.

  3. Helically linked mirror arrangement

    1986-08-01

    A scheme is described for helical linking of mirror sections, which endeavors to combine the better features of toroidal and mirror devices by eliminating the longitudinal loss of mirror machines, having moderately high average β and steady state operation. This scheme is aimed at a device, with closed magnetic surfaces having rotational transform for equilibrium, one or more axisymmetric straight sections for reduced radial loss, a simple geometrical axis for the links and an overall positive magnetic well depth for stability. We start by describing several other attempts at linking of mirror sections, made both in the past and the present. Then a description of our helically linked mirror scheme is given. This example has three identical straight sections connected by three sections having helical geometric axes. A theoretical analysis of the magnetic field and single-particle orbits in them leads to the conclusion that most of the passing particles would be confined in the device and they would have orbits independent of pitch angle under certain conditions. Numerical results are presented, which agree well with the theoretical results as far as passing particle orbits are concerned

    The multitude of different supplements recommended for animals grazing natural pastures, which testifies to the need for a metabolic basis for supplementary feeding practices. The first approach to this problem was to simulate different feeding conditions in the laboratory, where the metabolic responses of body tissues to changes in the supply of purified nutrients could be studied using radioisotope techniques. The second step was to link these fundamental studies to field conditions. The results of these studies suggest that the efficiency of feed conversion and growth rates of ruminants grazing winter pastures in the highveld region of South Africa could be substantially improved by strategic supplementation with glucose precursors. Acetate clearance rate represents a valuable link in the process of applying information obtained from controlled laboratory experiments to field conditions. As this technique is inexpensive, quick and simple to carry out, it is ideally suited to application under field conditions where the use of isotopes is impractical. By providing a link with field conditions, it greatly extended the scope and practical application of isotope tracer techniques

    2006-01-01

    Research and development works conducted in the Establishment for Nuclear Equipment (ZdAJ) were focused around 3 subject areas: an accelerator for cancer treatment, therapeutical tables, systems and methods for controlling objects that cross international borders. The new, medium energy accelerator for cancer therapy cases is being designed in the Establishment for several years. In 2005 progress was achieved. A physical part, containing an electron beam has been completed and the parameters of that beam make it useful for therapeutical purposes. Consequently, the work on designing and testing of beam control systems, ensuring its high stability, repetition of irradiation parameters and accuracy of dosage have been started. Results of these tests make it very probable that 2006 will be the final year of scientific works and in 2007 the new apparatus will be ready for sales. Therapeutical tables have become a leading product of ZdAJ IPJ. Their technical parameters, reliability and universality in uses are appreciated by many customers of ZdAJ. In 2005, the table Polkam 16 was registered by the national Office for Registration of Medical Equipment as the first product of ZdAJ that meets all technical and formal requirements of the safety mark CE. This allows sales of the product on the market of the European Union. The research and development part of designing a therapeutical table for uses in the total body irradiation technique was also concluded in 2005. After the September 11 terrorist attacks on WTC a matter of controlling international borders have become a priority for many countries. In 2005 in ZdAJ IPJ, we conducted many preliminary calculations and experiments analyzing systems of irradiation sources, both photon and neutron as well as systems of detection and designing of signals triggered by controlling objects crossing the border. The results so far have enabled us to formulate a research project which has been positively evaluated by experts and found

    Many Saskatchewan communities are interested in the potential benefits of establishing an ethanol production facility. A guide is presented to outline areas that communities should consider when contemplating the development of an ethanol production facility. Political issues affecting the ethanol industry are discussed including environmental impacts, United States legislation, Canadian legislation, and government incentives. Key success factors in starting a business, project management, marketing, financing, production, physical requirements, and licensing and regulation are considered. Factors which must be taken into consideration by the project manager and team include markets for ethanol and co-products, competent business management staff, equity partners for financing, production and co-product utilization technologies, integration with another facility such as a feedlot or gluten plant, use of outside consultants, and feedstock, water, energy, labour, environmental and site size requirements. 2 figs., 2 tabs

The main programme is nuclear and is concerned with the design and development of warheads for strategic and tactical nuclear weapons for the British nuclear deterrent, including those for the Royal Navy's missile carrying submarine fleet. The work is described grouped as design physics, development and materials. Services to these groups and to the whole establishment are provided by Engineering, Safety and Administration. The work ranges from long-term fundamental research, the development of technology, design, prototype development to the environmental testing of engineered products. In materials research the emphasis is on plutonium, uranium and beryllium, on high explosives and a wide range of inorganic and organic materials. The physics of the earth's crust is studied to aid detection of underground nuclear explosions. Reactor research facilities include the two reactors, Herald and Viper. (U.K.)

  14. Bringing back the bridge solution to establish a fixed link over the Strait of Gibraltar

    The aim of this essay is to address some of the aspects of the Bridge alternative and to examine the conclusions reached back in 1995 over the feasibility of such a solution. Although having been left aside for decades, the Bridge Solution of the Strait of Gibraltar Crossing Project has been brought back to life as an available alternative to close the gap between the two continents, being the reason to have recently detected some impediment down into the lower layers of the site laying grounds. All of which has revealed further geotechnical issues to tackle. Given the current level of development the Tunnel solution has reached, the 20-year-old Bridge solution needs to be fully updated in order to catch up with the former: As well as taking into consideration the new trends present in the state of the art on design of structures, the Bridge solution would also entail updating construction procedures if it is to incorporate all the potentialities offered by: (1) related tools (2) machinery, and (3), many new ideas which, coming from distinct industrial sectors others than the public works, have worked their way through the construction field. Furthermore, it would be necessary to bear in mind the ceaseless development materials science is going through, which involves constant increases in both levels of resilience and number of characteristics such materials present.

    Phosphorus is a highly reactive element that is essential for life and forms a variety of compounds in terrestrial and aquatic ecosystems. In water, phosphorus may be present as the orthophosphate ion (PO43-) and is also present in all life forms as an essential component of cellular material. In natural ecosystems, phosphorus is derived from the erosion of rocks and is conserved for plant growth as it is returned to the soil through animal waste and the decomposition of plant and animal tissue; but in agricultural systems, a portion of the phosphorus is removed with each harvest, especially since phosphorus is concentrated in the seeds and fruit. Phosphorus is added to soil by using chemical fertilizers, manure, and composted materials. Agricultural use of chemical phosphorus fertilizer, in the United States, in 2008 was 4,247,000 tons, which is an increase of 25 percent since 1964 (http://www.ers.usda.gov/Data/FertilizerUse/). Widely grown corn, soybeans, and wheat use the greatest amount of phosphorus fertilizer among agricultural crops.

    Full Text Available For many years, English has been studied apart from the other subjects in nonbilingual centres, isolating it from other knowledge areas, underestimating its nature as a vehicle for communication. English has thus been considered just as a set of rules to be memorized with no communicative purpose. As English teachers our objective to design this proposal, was to show this language as a useful tool, not only to be practiced in the classroom, but also in the context of other areas, in this case, science. Throughout the piloting of this project at Gustavo Restrepo school, in the south of Bogotá, English was used to learn science and science was used to practice English during the performance of some tasks with a communicative purpose so that the students of ninth grade had the opportunity to learn by doing.

    Full Text Available Job satisfaction pertains to people’s reactions and feelings towards their jobs. It is an indicator of emotional well-being or psychological health. On the other hand, subjective well-being refers to how people evaluate their lives which may include cognitive judgments and affective evaluations. With the aim of knowing the possible relationship between job satisfaction and subjective well-being, 251 teachers who came from 52 government schools were asked to respond to the Generic Job Satisfaction Scale (GJSS and the Satisfaction with Life Scale (SWLS. The item on the GJSS which registered the highest mean pertained to job security (M=4.35, SD=.62 while the lowest means were observed on items that pertained to concern of the management towards the teacher (M=4.04, SD=.61 and getting along with supervisors (M=4.04, SD=.64. As to the items in the SWLS, the highest mean was observed on the item that pertained to satisfaction with life (M=5.65, SD=1.09 while the item with lowest mean pertained to getting the important things one wants in life (M=5.21, SD=1.28. Generally, the participants of the study had high job satisfaction and subjective well-being. Also, it was revealed that job satisfaction was significantly related to subjective well-being with job satisfaction predicting subjective well-being.

    Full Text Available In the present report, we studied the associations that might exist between alcohol consumption, cognitive functions and diabetic pathology in patients with type 2 diabetes (T2D. The alcohol intake of 219 patients diagnosed with diabetes was classified into 6 groups: nondrinkers, 0.1-9.9, 10.0-14.9, 15.0-29.9, 30.0-49.9 and ≥ 50.0, according to the total amount (grams/day of alcohol consumption. Our results mainly confirm that moderate alcohol consumption can reduce some of the neuropathological aspects of T2D, as demonstrated by the decrease in glycemic levels in patients that consumed higher levels of alcohol (30.0-49.9 g/day, when compared to non-drinkers (p=0.04 or groups in which individuals consumed 0.1-9.9 g/day (p=0.01 and 10.0-14.9 g/day (p=0.02. Regarding the results of cognitive testing, we noticed a significant increase in the values of the MMSE score a lower dose of alcohol intake (0.1-9.9 g/day was compared with higher doses: 30.0-49.9 g/day (p=0.008 and ≥ 50.0 g/day (p=0.047.

    Carlos Julio Montoya Guarín

    1999-04-01

    Full Text Available A diferencia de lo observado para los linfocitos B, que reconocen antígenos libres en forma nativa, los linfocitos T han evolucionado para reconocer pequeños péptidos antigénicos presentados por moléculas de histocompatibilidad en la superficie de células presentadoras especializadas o de células diana. Para ello los linfocitos T maduros cuentan con un grupo de proteínas de membrana que en conjunto se denominan complejo TCR. Este grupo de cadenas polipeptídicas se expresan en la membrana de los linfocitos T y cumplen una función doble: reconocer los fragmentos antigénicos presentados por las moléculas de histocompatibilidad y transmitir las señales de ese reconocimiento al interior del linfocito. Las consecuencias de esta señalización pueden variar desde la activación funcional hasta la anergia o la apoptosis. Gracias a una intensa investigación en esta área, en los últimos años se han revelado muchas de las proteínas involucradas en la transducción de señales en los linfocitos T y sus mecanismos de acción. En esta revisión se examinan los modelos que explican la dinámica de la ligación del TCR, las principales vías de transducción de señales, los agentes farmacológicos que han permitido su estudio y dos modelos de enfermedades humanas que presentan entre sus mecanismos fisiopatológicos alteraciones en las vías de señalización a través del TCR. T lymphocytes, in contrast to B lymphocytes which bind free antigens in a native form, recognize little antigenic peptides displayed on histocompatibility molecules in the surface of specialized or target cells. For this, mature T lymphocytes have a group of membrane proteins that together are named TCR complex. This group of polypeptide chains expresses in the membrane and has a double function: to recognize the antigenic fragments bound to histocompatibility molecules and to transmit signals arisen from the recognition to the inner of the lymphocyte.

    2016-10-15

    Decommissioning has recently become an issue highlighted in Korea due to the Permanent Shutdown (PS) of Kori-1 plant. Since Korea Hydro and Nuclear Power (KHNP) Company decided the PS of Kori-1 instead of further continued operation, Kori-1 will be the first decommissioning plant of the commercial reactors in Korea. Korean regulatory authority demands Initial Decommissioning Plan (IDP) for all the plants in operation and under construction. In addition, decommissioning should be considered for the completion of the life cycle of NPPs. To date, Korea has no experience regarding decommissioning of the commercial reactor and a lot of uncertainties will be expected due to its site-specific factors. However, optimized decommissioning process schedule must be indispensable in the safety and economic efficiency of the project. Differed from USA, Korea has no experience and know-hows of the operation and site management for decommissioning. Hence, in Korea, establishment of decommissioning schedule has to give more weight to safety than precedent cases. More economical and rational schedule will be composed by collecting and analyzing the experience data and site-specific data and information as the decommissioning progresses. In a long-range outlook, KHNP having capability of NPP decommissioning will try to decommissioning business in Korea and foreign countries.

    1979-01-01

    1978 was the second year in the Joint Research Centre's 1977-1980 multiannual research programme. Since the following exercise is intended to run from 1980 to 1983 with a one year overlap, new proposals will be placed before the Council of Ministers in 1979. To this end, a considerable part of the programme and project management staff activities has been devoted to the peliminary preparation of future plans. In general it is expected that the Establishment's three research activities will continue along the lines already proceeding successfully in the present programme in the materials testing reactor (HFR), high temperature materials and organic chemistry spheres with some updating and refocussing where necessary. Consultation with the appropriate Advisory Committees for Programme Management has been contributed to these processes. Another important development has been the question of site security, following decisions of the European Commission and the Dutch Government to apply International Atomic Agency regulations. The work to apply the necessary measures has had to be executed in the shortest possible time. We have endeavoured to maintain and increase for all three programmes the already intensive contacts with research institutes and industry in the Member States. Important in this connection are the international conferences, 'Alloy 800' held in March and 'Ramping and Load following Behaviour of Reactor Fuel' in December, as well as an international meeting of the 'irradiation Devices Working Party' which took place in May

    Full Text Available En los colibríes la memoria espacial desempeña un papel importante durante el forrajeo. Éste se basa en el uso de señales específicas (visuales o en señales espaciales (localización de flores y plantas con néctar. Sin embargo, el uso de estas señales por los colibríes puede variar de acuerdo con la escala espacial que enfrentan cuando visitan flores de una o más plantas durante el forrajeo; ésto se puso a prueba con individuos del colibrí cola-ancha Selasphorus platycercus. Por otro lado, para evaluar la posible variación en el uso de las señales, se llevaron a cabo experimentos en condiciones semi-naturales utilizando flores de la planta Penstemon roseus, nativa del sitio de estudio. A través de la manipulación de la presencia/ausencia de una recompensa (néctar y señales visuales, evaluamos el uso de la memoria espacial durante el forrajeo entre 2 plantas (experimento 1 y dentro de una sola planta (experimento 2. Los resultados demostraron que los colibríes utilizaron la memoria de localización de la planta de cuyas flores obtuvieron recompensa, independientemente de la presencia de señales visuales. Por el contrario, en flores individuales de una sola planta, después de un corto periodo de aprendizaje los colibríes pueden utilizar las señales visuales para guiar su forrajeo y discriminar las flores sin recompensa. Asimismo, en ausencia de señales visuales los individuos basaron su forrajeo en la memoria de localización de la flor con recompensa visitada previamente. Estos resultados sugieren plasticidad en el comportamiento de forrajeo de los colibríes influenciada por la escala espacial y por la información adquirida en visitas previas.In hummingbirds spatial memory plays an important role during foraging.

    2013-01-01

    Full Text Available Collagen cross-linking (CXL has become the standard of care for progressive keratoconus, after numerous clinical studies have established its efficacy and safety in suitably selected eyes. The standard protocol is applicable in eyes which have a minimum corneal thickness of 400 μm after epithelial debridement. This prerequisite was stipulated to protect the corneal endothelium and intraocular tissues from the deleterious effect of ultraviolet-A (UVA radiation. However, patients with keratoconus often present with corneal thickness of less than 400 μm and could have otherwise benefited from this procedure. A few modifications of the standard procedure have been suggested to benefit these patients without a compromise in safety. Transepithelial cross-linking, pachymetry-guided epithelial debridement before cross-linking, and the use of hypoosmolar riboflavin are some of the techniques that have been attempted. Although clinical data is limited at the present time, these techniques are worth considering in patients with thin corneas. Further studies are needed to scientifically establish their efficacy and safety.

    Various aspects of knot theory are discussed when fermionic degrees of freedom are taken into account in the braid group representations and in the state models. It is discussed how the R matrix for the Alexander polynomial arises from the Fox differential calculus, and how it is related to the quantum group U q gl(1,1). New families of solutions of the Yang Baxter equation obtained from ''linear'' representations of the braid group and exterior algebra are investigated. State models associated with U q sl(n,m), and in the case n=m=1 a state model for the multivariable Alexander polynomial are studied. Invariants of links in solid handlebodies are considered and it is shown how the non trivial topology lifts the boson fermion degeneracy is present in S 3 . (author) 36 refs

We base our examination in part on the classic positions of the wayfi nding literature—for example, Lynch’s seminal study, The Image of the City ( 1960 ). However, we also examine the so......-called mobilities turn in which mobility is viewed as a complex, multilayered process that entails much more than simply getting from point A to point B (see Cresswell 2006 ; Jensen 2013 ; Urry 2007 ).The structure of the chapter is simple: We fi rst introduce the concepts that are key to linking wayfi nding...

  5. Named Entity Linking Algorithm

    2017-01-01

    Full Text Available In the tasks of processing text in natural language, Named Entity Linking (NEL represents the task to define and link some entity, which is found in the text, with some entity in the knowledge base (for example, Dbpedia. Currently, there is a diversity of approaches to solve this problem, but two main classes can be identified: graph-based approaches and machine learning-based ones. Graph and Machine Learning approaches-based algorithm is proposed accordingly to the stated assumptions about the interrelations of named entities in a sentence and in general.In the case of graph-based approaches, it is necessary to solve the problem of identifying an optimal set of the related entities according to some metric that characterizes the distance between these entities in a graph built on some knowledge base. Due to limitations in processing power, to solve this task directly is impossible. Therefore, its modification is proposed. Based on the algorithms of machine learning, an independent solution cannot be built due to small volumes of training datasets relevant to NEL task. However, their use can contribute to improving the quality of the algorithm. The adaptation of the Latent Dirichlet Allocation model is proposed in order to obtain a measure of the compatibility of attributes of various entities encountered in one context.The efficiency of the proposed algorithm was experimentally tested. A test dataset was independently generated. On its basis the performance of the model was compared using the proposed algorithm with the open source product DBpedia Spotlight, which solves the NEL problem.The mockup, based on the proposed algorithm, showed a low speed as compared to DBpedia Spotlight. However, the fact that it has shown higher accuracy, stipulates the prospects for work in this direction.The main directions of development were proposed in order to increase the accuracy of the system and its productivity.

  9. Teleoperation over low bandwidth communication links

    International Nuclear Information System (INIS)

    Fryer, R.J.; Mair, G.M.; Clark, N.; Heng, J.

    1996-01-01

    Teleoperation is well established for many areas of hazardous environment working. Where such environments are well structured and contained, such as within a working plant, communications bandwidths need not be a constraining factor. However where the worksite is remote, large, poorly structured or damaged communications rapidly become a critical factor in the efficient deployment and use of teleoperation equipment. The paper justifies and describes means which we are exploring to reduce the required communications bandwidth for teleoperation whist retaining full functionality. Techniques involved include incorporation of local intelligence at the worksite, with bandwidth devoted to high-level up-link control signals and down-link feedback, and the use of highly compressed video feeding 'virtual reality type' HMDs to provide maximum system transparency for the operator. The work is drawing on previous experience with an 'anthropomorphic robot heat' for telepresence work, and proprietary algorithms capable of compressing full colour video to standard telephone modem data rates.

    Full Text Available Since the advent of Linked Data (LD as a method for building webs of data, there have been many attempts to apply and implement LD in various settings. Efforts have been made to convert bibliographic data in libraries into Linked Data, thereby generating Library Linked Data (LLD. However, when memory institutions have tried to link their data with external sources based on principles suggested by Tim Berners-Lee, identifying appropriate vocabularies for use in describing their bibliographic data has proved challenging. The objective of this paper is to discuss the potential role of Linked Open Vocabularies (LOV in providing better access to various open datasets and facilitating effective linking. The paper will also examine the ways in which memory institutions can utilize LOV to enhance the quality of LLD and LLD-based ontology design.

    Objective Injury, the most common type of pediatric trauma, can lead to a number of adverse psychosocial outcomes, including posttraumatic stress disorder. Currently, few evidence-based parent programs exist to support children hospitalized after a traumatic injury. Using methods in evaluation and intervention research, we completed a formative research study to develop a new program of psychological first aid, Link for Injured Kids, aimed to educate parents in supporting their children after a severe traumatic injury. Methods Using qualitative methods, we held focus groups with parents and pediatric trauma providers of children hospitalized at a Level I Children's Hospital because of an injury in 2012. We asked focus group participants to describe reactions to trauma and review drafts of our intervention materials. Results Health professionals and caregivers reported a broad spectrum of emotional responses by their children or patients; however, difficulties were experienced during recovery at home and upon returning to school. All parents and health professionals recommended that interventions be offered to parents either in the emergency department or close to discharge among admissions. Conclusions Results from this study strongly indicate a need for posttrauma interventions, particularly in rural settings, to support families of children to address the psychosocial outcomes in the aftermath of an injury. Findings presented here describe the process of intervention development that responds to the needs of an affected population. PMID:26428077

  14. The CMS link system

    The Compact Muon Solenoid (CMS) is a multi-purpose detector that is going to be installed in the future Large Hadron Collider (LHC) at CERN. Muons are one of the main physical signatures of the expected new physics. The muons are going to be detected by the Central Tracker (CT) and the Muon Spectrometer (MS). Both, the CT and MS can provide an independent muon momentum measurement, but for all η and momentum values the highest precision for muon momentum measurement is achieved when the muon tracks are reconstructed using both tracking detectors. The calorimeters and the solenoid volumes separate about three meters the CT and the MS. It has been shown that the alignment of the CT with respect to the MS can not be guaranteed by a software alignment in a reasonable time scale. Therefore, an opto-mechanical system (the multipoint link system) have been designed to monitor, on-line, the relative position of both sub-detectors providing a common reference frame for both of them. The local alignment of the muon barrel spectrometer determines the relative position of the muon chambers with respect to themselves and also with respect to a carbon fiber rigid structure called MAB (Module for the Alignment of the Barrel). There are a total of 36 MABs distributed in the boundary planes of each muon spectrometer sector. This paper describes all the equipment and presents the principle of measurement. (author)

    Full Text Available Introduction The number of patients suffering from diabetes mellitus is growing globally. It is expected to observe 253.4 million sufferers in geriatric population in 2045. In this time, also 131.5 million of people is going to have dementia and other cognitive problems. In people aged over 65 these two diseases are concomitant quite often. What are the connections in the area of etiology and treatment? Aim The purpose of this study is to present links between dementia and diabetes are depicted in professional literature. Results Diabetes and dementia are associated on many levels. These conditions have common risk factors. Diabetes may contribute to cognitive impairment in many ways, promoting development of atherosclerosis, brain vessel damage and vascular dementia. Alzheimer disease may be promoted by hyperglycemia and hyperinsulinemia. On contrary also hypoglycaemia, often met in elderly diabetic patients has negative impact on cognitive function. Dementia seriously affects treatment of diabetes. The main problems are not satisfying adherence and diabetes self-management. Conclusions Prevention of diabetes and dementia risk factors can be performed simultaneously as the are common for both diseases. Enhancing physical activity, reducing saturated fats consumption, levels of cholesterol and body mass are considered to be beneficial in the context of described conditions. Furthermore, treatment of diabetes is strongly affected by cognitive dysfunction. Management of dementive diabetics requires individualization and using long-acting drugs. It is crucial to reduce risk of life-threatening hypoglycaemias and to create wide team to take care of these patients.

  16. Hierarchical Linked Views

    Energy Technology Data Exchange (ETDEWEB)

    Erbacher, Robert; Frincke, Deb

    2007-07-02

    Coordinated views have proven critical to the development of effective visualization environments. This results from the fact that a single view or representation of the data cannot show all of the intricacies of a given data set. Additionally, users will often need to correlate more data parameters than can effectively be integrated into a single visual display. Typically, development of multiple-linked views results in an adhoc configuration of views and associated interactions. The hierarchical model we are proposing is geared towards more effective organization of such environments and the views they encompass. At the same time, this model can effectively integrate much of the prior work on interactive and visual frameworks. Additionally, we expand the concept of views to incorporate perceptual views. This is related to the fact that visual displays can have information encoded at various levels of focus. Thus, a global view of the display provides overall trends of the data while focusing in on individual elements provides detailed specifics. By integrating interaction and perception into a single model, we show how one impacts the other. Typically, interaction and perception are considered separately, however, when interaction is being considered at a fundamental level and allowed to direct/modify the visualization directly we must consider them simultaneously and how they impact one another.

    of JCE in the mail each month, and I expect you do too. I can glance at the cover to get an overview of an issue's content, and I usually am enticed inside by intriguing cover art. I can scan the table of contents to find articles I want to read, or I can just browse through the issue to see what looks interesting. Usually the editors have juxtaposed related articles so that I often find a small treasure trove. The printed Journal is quite portable and can be read in a car or airplane. It will last a long time, and until the paper deteriorates, I will never have a problem reading back issues. I have almost every issue from the first day I subscribed and have even added some older ones from collections of retired colleagues who no longer had shelf space for them. I certainly would not want to give up my printed copies, and I want to keep getting them. I find that JCE Online provides a different kind of resource that is equally valuable. It contains more information, and information that is more appropriate in electronic form. It links related ideas into a much more complex web of information than is possible in print. And it opens pathways to lots of information that is not part of JCE but resides elsewhere. Using this issue as an example, let's take a tour of what JCE Online can do. Point your Web browser to http://jchemed.chem.wisc.edu Click on Journal and then on Current Issue (unless September 1999 is no longer the current issue, in which case you will find it in Past Issues). In the table of contents, find the article "UV Catalysis, Cyanotype Photography, and Sunscreens". Click on the title. When the abstract appears, click on Full Text (PDF) to see the article, just as it appears on page 1199 in this issue.

    Eichmann, David (Editor); Beck, Jon; Atkins, John; Bailey, Bill

    1992-01-01

    This topic is covered in three sections. The first section explores some of the architectural ramifications of extending the Eichmann/Atkins lattice-based classification scheme to encompass the assets of the full life cycle of software development. A model is considered that provides explicit links between objects in addition to the edges connecting classification vertices in the standard lattice. The second section gives a description of the efforts to implement the repository architecture using a commercially available object-oriented database management system. Some of the features of this implementation are described, and some of the next steps to be taken to produce a working prototype of the repository are pointed out. In the final section, it is argued that design and instantiation of reusable components have competing criteria (design-for-reuse strives for generality, design-with-reuse strives for specificity) and that providing mechanisms for each can be complementary rather than antagonistic. In particular, it is demonstrated how program slicing techniques can be applied to customization of reusable components.

    1993-01-01

    A new study around the Aldermaston and Burghfield nuclear weapons establishments published in the British Medical Journal has found a similar association between the risk of childhood leukaemia and employment in the nuclear industry to that found by Professor Gardner in 1990 at Sellafield. It suggests that occupational exposure to radiation prior to conception increases the risk of a subsequent child developing leukaemia by 9 times. It is clear that working at Aldermaston or Burghfield does not explain the entire excess of cancers -there must be another factor at work. The one factor that Aldermaston, Burghfield, Sellafield and Dounreay where a similar pattern is found, have in common is plutonium. Whilst further studies are important to determine the role played by plutonium, it should be declared 'guilty until proven innocent'. The production and use of plutonium should cease immediately.

    Radiopharmaceuticals are nowadays under the responsibility of the radio-pharmacist because of their medicinal product status. Radiopharmacy belongs to the hospital pharmacy department, nevertheless, interactions with nuclear medicine department are important: rooms are included or located near nuclear medicine departments in order to respect radiation protection rules, more over staff, a part of the material and some activities are shared between the two departments. Consequently, it seems essential to formalize links between the radiopharmacy and the nuclear medicine department, setting the goals to avoid conflicts and to ensure patients' security. Modalities chosen for this formalization will depend on the establishment's organization. (authors)

    Full Text Available According to common perception, hypothyroidism is held responsible for obesity. However, linking them causally is controversial. Overt hypothyroidism is associated with modest weight gain, but there is a lack of clarity regarding subclinical hypothyroidism. Novel view indicates that changes in thyroid-stimulating hormone (TSH could well be secondary to obesity. The increasing prevalence of obesity further confounds definition of normal TSH range in population studies. Thyroid autoantibody status may help in establishing the diagnosis of subclinical hypothyroidism in obesity. High leptin levels may play a role in the hyperthyrotropinemia of obesity and also increase susceptibility to thyroid autoimmunity and subsequent hypothyroidism. There is at most a modest effect of L-T4 treatment in overt hypothyroidism in inducing weight loss; benefit in subclinical hypothyroidism is not established with no data supporting thyroid hormone use in euthyroid obese patients.

    -change-feedback processes, bridge basic soil science research and management, and facilitate the communication between science and society . To meet these challenges an international community effort is required, similar to initiatives in systems biology, hydrology, and climate and crop research. We therefore propose to establish an international soil modelling consortium with the aims of 1) bringing together leading experts in modelling soil processes within all major soil disciplines, 2) addressing major scientific gaps in describing key processes and their long term impacts with respect to the different functions and ecosystem services provided by soil, 3) intercomparing soil model performance based on standardized and harmonized data sets, 4) identifying interactions with other relevant platforms related to common data formats, protocols and ontologies, 5) developing new approaches to inverse modelling, calibration, and validation of soil models, 6) integrating soil modelling expertise and state of the art knowledge on soil processes in climate, land surface, ecological, crop and contaminant models, and 7) linking process models with new observation, measurement and data evaluation technologies for mapping and characterizing soil properties across scales. Our consortium will bring together modelers and experimental soil scientists at the forefront of new technologies and approaches to characterize soils. By addressing these aims, the consortium will contribute to improve the role of soil modeling as a knowledge dissemination instrument in addressing key global issues and stimulate the development of translational research activities. This presentation will provide a compelling case for this much-needed effort, with a focus on tangible benefits to the scientific and food security communities.

    Full Text Available El virus de la Lengua azul (VLA es un ARN virus de doble cadena que induce apoptosis tanto en cultivos celulares como en tejidos blanco. Con el fin de dilucidar el mecanismo de apoptosis en la infección por el VLA, en el presente trabajo examinamos en detalle, por la técnica de Western blot, las señales celulares de caspasas, Bax, citocromo c, Smac/DIABLO y factor nuclear kappa B (NF-kB que se activan en la infección viral. Hemos comprobado que luego de la infección in vitro con el VLA, se detectó la activación de la caspasa 8 y con ello el mecanismo extrínseco de la apoptosis. También detectamos por primera vez no sólo la activación de miembros de la familia Bcl-2 (Bax, sino también la liberación del citocromo c y la proteína Smac/DIABLO, confirmando que en la infección por el VLA está involucrado el mecanismo secuencial intrínseco de la apoptosis. Asimismo, demostramos que la infección por el VLA activa el NF-kB y que la apoptosis es sustancialmente reducida mediante la inhibición del mismo. La activación de las señales celulares tales como Bax, citocromo c, Smac/DIABLO y NF-kB presentados en este trabajo, esclarecen los mecanismos apoptóticos durante la infección por el VLA para una mayor comprensión del papel primario que juega la apoptosis en la patogénesis del virus.Bluetongue (BTV is a double-stranded RNA virus that induces apoptosis both in mammalian cell cultures and in target tissues. To elucidate the apoptosis pathways in BTV infection, we have examined in detail the apoptosis mechanism by examination of caspases, Bax, cytochrome c, Smac/DIABLO and NF-kB signalling pathways. In this report, after cell infection with BTV, the activation of caspase 8 was detected, proving the extrinsic receptor binding apoptotic pathway.

    Full Text Available Las hembras de los mosquitos vectores de enfermedades utilizan señales físicas y químicas para localizar su fuente de alimentación sanguínea en hospederos vertebrados. Los mosquitos zoofílicos responden preferentemente al CO2 y al octenol liberados en la respiración y excreciones, mientras que los mosquitos antropofílicos responden al ácido láctico y a una variedad de compuestos del sudor. Estos compuestos son modificados por microrganismos saprófitos de las glándulas sebáceas de la piel. Otros factores presentes en las viviendas contribuyen a la integración de microsistemas constituidos por olores característicos, que explican los diferentes niveles de atracción de mosquitos y la focalización de la transmisión del paludismo a una porción de casas en localidades de áreas endémicas. La identificación de estos atrayentes químicos y sus moléculas receptoras en mosquitos puede ser utilizada como complemento de nuevos métodos para la vigilancia epidemiológica, para atraer a los mosquitos a trampas de colecta o para incrementar su contacto con insecticidas usados en su control, así como en la manipulación genética para desviar las picaduras de los mosquitos hacia otros hospederos vertebrados.

    To assess the opinions of dental hygienists in Saudi Arabia regarding the establishment of a professional association including the role it should have to meet their professional needs. A cross-sectional electronic survey using Qualtrics was utilized. IRB exemption was obtained prior to distribution. Although there are 298 licensed Saudi dental hygienists in Saudi Arabia, email addresses were only available for 101 respondents: those obtained previously by direct contact for the purpose of initiation of a professional association and those referred by the direct contacts. Subjects were emailed a link to the survey. Seventy-seven subjects responded fully to the survey yielding a response rate of 70.3%. Most 91.5% (n = 65) of the respondents favoured the establishment of a Saudi dental hygiene professional association. Eighty-eight per cent (n = 59) responded that such an association would promote development of the profession in the country at least somewhat and 86.6% (n = 58) agreed that their professional needs could be met by its establishment. Interestingly, half of those who did not support the creation of the professional association believed it would promote development of the profession and meet professional needs. A representative sample of dental hygienists in Saudi Arabia support the establishment of a professional association and feel that it would advocate and promote the dental hygiene profession in the country and meet their professional needs. © 2018 John Wiley & Sons A/S.

  3. Strategii de reducere a deficitelor şi datoriei publice a Statelor Unite ale Americii adoptate de Administraţia Obama

    Directory of Open Access Journals (Sweden)

    Full Text Available At the beginning of the second decade of the 21st century, the sovereign debts of one of the largest economies of the world were “blown up” because of the ageing population and the costs determined by the financial crisis. According to an analysis by Standard & Poor’s rating agency, if governments maintain current fiscal policies, for 49 states representing 2/3 of the world population, the average debt as percentage of GDP will reach 245% by 2050. "The pressure of increasing expenses will determine profound changes in the economical perspectives of these countries. The erosion will start in 2015, when the quota of many states with high rating will start being under pressure", declare the Agency’s analysis. In mid April 2011, Barack Obama announced the elaboration of an ambitious plan for the reduction of the federal budget deficit, in total amount of USD 4,000 billion, over a period of 12 years. Democrat and Republican leaders of the Congress reached an agreement in respect to the raise of the debt limits, after months of intense closed-doors negotiations and only two days before the due date set by the Ministry of Finance. In order to avoid payment default, democrats and republicans reached an agreement to increase the leveraging to USD 14,300 billion, by USD 2,100 billion. Moreover, this agreement establishes a reduction of governmental expenses for the next 10 years with up to USD 3,000 billion and enough loans in order to avoid another increase in the leveraging limits in 2013. In turn, FED announced they will maintain stimulating policies for another two years, although in June the economic stimulation program should have ended. The monetary policy interest rate is at the lowest level in the history of the Central Bank, between 0% and 0.25% since 2008. At the beginning of September, President Barack Obama presented a new plan of economic revival and labor market support for a period of six years, rounded at USD 447 billion, in the

  12. ‘Quadrilateral’ in Philosophy and Bie-modernism (Comments on Aleš Erjavec’s “Zhuyi: From Absence to Bustle? Some Comments on Wang Jianjiang's Article ‘The Bustle and the Absence of Zhuyi’”

    Directory of Open Access Journals (Sweden)

    Wang Jianjiang

    2017-09-01

    Full Text Available Aleš Erjavec proposed the global philosophical quadrilateral, giving Chinese philosophy, aesthetics, and humanities an expectation. However, the realization of this expectation hinges on the question whether Chinese philosophy as well as aesthetics and the humanities can rid themselves of the staggering level of ‘voice’ and develop their ‘speech’. To make ‘speech’, any nation should have its own idea, theory and Zhuyi. How to overcome the embarrassment that ‘quadrilateral’ expectation implies? Time spatialization and four-phase development theories of the Bie-modern, and great leap forward pause theory have provided an answer. The quadrilateral expectation as shown by Aleš Erjavec, is encountering the antagonism between ‘cosmopolitanism’ and ‘nationalism’. The key to resolving this antagonism is ‘my’ original achievement consisting of ‘Chinese traditional philosophy, Western philosophy, Marxism and I (myself’. Bie-modernism is a Zhuyi of self-regulation, self-renewal and self-transcendence and of their practical implementation.   Article received: May 21, 2017; Article accepted: May 24, 2017; Original scholarly paper How to cite this article: Jianjiang, Wang.

    Wrist and knee radiographs from children with X-linked hypophosphatemic rickets were analyzed and compared with those from normal children and children with established rickets to assess whether radiographically apparent rickets is a consistent abnormality in X-linked hypophosphatemia. The absence or presence of rickets was correctly identified in 94.8% of wrist and knee films from normal and positive controls. In contrast, patients with X-linked hypophosphatemia exhibited rachitic abnormalities in only 5 of 11 wrist and 13 of 15 knee radiographs. Our data indicate that radiographically detectable rickets is a variable abnormality of X-linked hypophosphatemia and does not provide an unambiguous index for the diagnosis of this disease.

    1988-01-01

    It is possible to expand the data acquisition capabilities of an existing process computer to include other dedicated computer based systems, provided each system has at least minimal data link capabilities. The following paper discusses the addition of three computer based acquisition systems to a Honeywell 4500C (also designated the 45000) running the SEER system. Only one data link port was required to support the link. Each of the three specialized systems implemented data link protocols used by their suppliers in previous projects: none of the three were compatible with Honeywell's protocol. Part one of the following provides a generic overview of the project and would be relevent to the operator of any process system interested in expansion. Part two provides specific details of this project and may serve to provide performance benchmarks to those who wish to consider a similar project

  4. Moisture availability limits subalpine tree establishment.

    Science.gov (United States)

    Andrus, Robert A; Harvey, Brian J; Rodman, Kyle C; Hart, Sarah J; Veblen, Thomas T

    2018-03-01

    In the absence of broad-scale disturbance, many temperate coniferous forests experience successful seedling establishment only when abundant seed production coincides with favorable climate. Identifying the frequency of past establishment events and the climate conditions favorable for seedling establishment is essential to understanding how climate warming could affect the frequency of future tree establishment events and therefore future forest composition or even persistence of a forest cover. In the southern Rocky Mountains, USA, research on the sensitivity of establishment of Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa)-two widely distributed, co-occurring conifers in North America-to climate variability has focused on the alpine treeline ecotone, leaving uncertainty about the sensitivity of these species across much of their elevation distribution. We compared annual germination dates for >450 Engelmann spruce and >500 subalpine fir seedlings collected across a complex topographic-moisture gradient to climate variability in the Colorado Front Range. We found that Engelmann spruce and subalpine fir established episodically with strong synchrony in establishment events across the study area. Broad-scale establishment events occurred in years of high soil moisture availability, which were characterized by above-average snowpack and/or cool and wet summer climatic conditions. In the recent half of the study period (1975-2010), a decrease in the number of fir and spruce establishment events across their distribution coincided with declining snowpack and a multi-decadal trend of rising summer temperature and increasing moisture deficits. Counter to expected and observed increases in tree establishment with climate warming in maritime subalpine forests, our results show that recruitment declines will likely occur across the core of moisture-limited subalpine tree ranges as warming drives increased moisture deficits. © 2018 by the

    Nikonov, Igor M [M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics, Moscow (Russian Federation)

    2012-08-31

    Graph-links arise as the intersection graphs of turning chord diagrams of links. Speaking informally, graph-links provide a combinatorial description of links up to mutations. Many link invariants can be reformulated in the language of graph-links. Khovanov homology, a well-known and useful knot invariant, is defined for graph-links in this paper (in the case of the ground field of characteristic two). Bibliography: 14 titles.

    2012-06-01

    Full Text Available Abstract Background Establishment success in newly founded populations relies on reaching the established phase, which is defined by characteristic fluctuations of the population’s state variables. Stochastic population models can be used to quantify the establishment probability of newly founded populations; however, so far no simple but robust method for doing so existed. To determine a critical initial number of individuals that need to be released to reach the established phase, we used a novel application of the “Wissel plot”, where –ln(1 – P0(t is plotted against time t. This plot is based on the equation P0t=1–c1e–ω1t, which relates the probability of extinction by time t, P0(t, to two constants: c1 describes the probability of a newly founded population to reach the established phase, whereas ω1 describes the population’s probability of extinction per short time interval once established. Results For illustration, we applied the method to a previously developed stochastic population model of the endangered African wild dog (Lycaon pictus. A newly founded population reaches the established phase if the intercept of the (extrapolated linear parts of the “Wissel plot” with the y-axis, which is –ln(c1, is negative. For wild dogs in our model, this is the case if a critical initial number of four packs, consisting of eight individuals each, are released. Conclusions The method we present to quantify the establishment probability of newly founded populations is generic and inferences thus are transferable to other systems across the field of conservation biology. In contrast to other methods, our approach disaggregates the components of a population’s viability by distinguishing establishment from persistence.

    2011-01-01

    A swarming mobile sensor network is comprised of a swarm of wirelessly connected mobile robots equipped with various sensors. Such a network can be applied in an uncertain environment for services such as cooperative navigation and exploration, object identification and information gathering. One of the most advantageous properties of the swarming wireless sensor network is that mobile nodes can work cooperatively to organize an ad-hoc network and optimize the network link capacity to maximize the transmission of gathered data from a source to a target. This paper describes a new method of link optimization of swarming mobile sensor networks. The new method is based on combination of the artificial potential force guaranteeing connectivities of the mobile sensor nodes and the max-flow min-cut theorem of graph theory ensuring optimization of the network link capacity. The developed algorithm is demonstrated and evaluated in simulation.

    S100A4 is implicated in metastasis and chronic inflammation, but its function remains uncertain. Here we establish an S100A4-dependent link between inflammation and metastatic tumor progression. We found that the acute-phase response proteins serum amyloid A (SAA) 1 and SAA3 are transcriptional...... targets of S100A4 via Toll-like receptor 4 (TLR4)/nuclear factor-κB signaling. SAA proteins stimulated the transcription of RANTES (regulated upon activation normal T-cell expressed and presumably secreted), G-CSF (granulocyte-colony-stimulating factor) and MMP2 (matrix metalloproteinase 2), MMP3, MMP9...... and MMP13. We have also shown for the first time that SAA stimulate their own transcription as well as that of proinflammatory S100A8 and S100A9 proteins. Moreover, they strongly enhanced tumor cell adhesion to fibronectin, and stimulated migration and invasion of human and mouse tumor cells...

  1. [Clinical application of super-link system theory in spinal cord injury patients during rehabilitation stage].

    Science.gov (United States)

    Chen, Hsiao-Yu

    2008-04-01

    The purpose of this paper is to introduce Super-Link System Theory, which is a theory of spinal cord injury rehabilitation. This theory has been developed using the grounded theory research method. By explaining the procedure for establishing a super-link system the paper explains the complex structure of this theory. Super-Link System Theory emphasizes that rehabilitation nurses 'build up their interpersonal relationships' with clients, family caregivers, the interdisciplinary team, and the community, and attempt to 'establish links' among them. They know these links have to be made with appropriate 'timing', and must be able to access the appropriate people when necessary. Super-link systems include the following four links: link to client with spinal cord injury, link to family caregiver, link to interdisciplinary rehabilitation team, and link to community. It can enable rehabilitation nurses to provide a better quality of nursing care to clients and their family caregivers, as well as promote their professional position in the interdisciplinary rehabilitation team.

    Inspired by the missing (new) link prediction and the spurious existing link identification in link prediction theory, this paper establishes an auxiliary optimization method for public transit route network (PTRN) based on link prediction. First, link prediction applied to PTRN is described, and based on reviewing the previous studies, the summary indices set and its algorithms set are collected for the link prediction experiment. Second, through analyzing the topological properties of Jinan’s PTRN established by the Space R method, we found that this is a typical small-world network with a relatively large average clustering coefficient. This phenomenon indicates that the structural similarity-based link prediction will show a good performance in this network. Then, based on the link prediction experiment of the summary indices set, three indices with maximum accuracy are selected for auxiliary optimization of Jinan’s PTRN. Furthermore, these link prediction results show that the overall layout of Jinan’s PTRN is stable and orderly, except for a partial area that requires optimization and reconstruction. The above pattern conforms to the general pattern of the optimal development stage of PTRN in China. Finally, based on the missing (new) link prediction and the spurious existing link identification, we propose optimization schemes that can be used not only to optimize current PTRN but also to evaluate PTRN planning.

  7. Critical factors in the establishment of allopolyploids.

    Science.gov (United States)

    Fowler, Norma L; Levin, Donald A

    2016-07-01

    The growth and spread of new polyploid populations have been explained in terms of fitness advantages over their diploid progenitors. However, a fitness advantage is not sufficient to insure the establishment of a polyploid; it must also overcome the obstacles of demographic stochasticity and minority disadvantage. Several studies have addressed the population dynamics of autopolyploids, but the present study is the first to consider allopolyploids, which are affected by more factors than autopolyploids. We constructed a population dynamic model of four types of plants (two parent species, hybrids, allopolyploids) that also included an explicit breeding system. The numbers of plants of each type were the most important factors determining whether the new allopolyploid would become established. More polyploid plants greatly increased the likelihood of polyploid persistence. More plants of the parent species and more hybrids resulted in more polyploids being produced. The model parameters with the most effect on polyploid establishment were potential population size (K), individual plant fecundity, and niche separation (α). The most important breeding system parameters were selfing rates, which mitigated minority disadvantage imposed by pollen limitation. The importance of population sizes, and the parameters that controlled them, in overcoming demographic stochasticity parallels the well-recognized role of propagule pressure in determining the success of invasive species. We modeled the establishment of a new allopolyploid; analogous considerations would affect the establishment of a new autopolyploid. The critical role of population sizes in polyploid establishment should be more widely recognized. © 2016 Botanical Society of America.

  8. Establishing community trust at radioactively contaminated sites

    International Nuclear Information System (INIS)

    Simpson, E.

    1999-01-01

    Establishing community trust is an essential element in the successful remediation of a radioactively contaminated site. The US Environmental Protection Agency (EPA), Region 2 has been involved in the clean up of numerous radioactively contaminated Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Resource Conservation Recovery Act (RCRA), and Formerly Utilized Site Remedial Action Program (FUSRAP) sites in New Jersey and New York. Each site presented a unique challenge which centered around establishing and, often, re-establishing the trust of the surrounding community. Thanks to the United States government's history regarding the use of radioactive materials, people question whether governmental regulators could possibly have the public's best interests in mind when it comes to addressing radioactively contaminated sites. It has been our experience that EPA can use its position as guardian of the environment to help establish public confidence in remedial actions. The EPA can even use its position to lend credibility to remedial activities in situations where it is not directly responsible for the clean-up. Some ways that we have found to instill community confidence are: establishing radioanalytical cross-check programs using EPA's National Air and Radiation Environmental Laboratory to provide analytical quality assurance; and establishing an environmental radiation monitoring program for the contaminated site and surrounding community.

  9. Establishing model credibility involves more than validation

    International Nuclear Information System (INIS)

    Kirchner, T.

    1991-01-01

    One widely used definition of validation is that the quantitative test of the performance of a model through the comparison of model predictions to independent sets of observations from the system being simulated. The ability to show that the model predictions compare well with observations is often thought to be the most rigorous test that can be used to establish credibility for a model in the scientific community. However, such tests are only part of the process used to establish credibility, and in some cases may be either unnecessary or misleading. Naylor and Finger extended the concept of validation to include the establishment of validity for the postulates embodied in the model and the test of assumptions used to select postulates for the model. Validity of postulates is established through concurrence by experts in the field of study that the mathematical or conceptual model contains the structural components and mathematical relationships necessary to adequately represent the system with respect to the goals for the model. This extended definition of validation provides for consideration of the structure of the model, not just its performance, in establishing credibility. Evaluation of a simulation model should establish the correctness of the code and the efficacy of the model within its domain of applicability. (24 refs., 6 figs.)

    Full Text Available Abstract X-linked alpha thalassaemia mental retardation (ATR-X syndrome in males is associated with profound developmental delay, facial dysmorphism, genital abnormalities and alpha thalassaemia. Female carriers are usually physically and intellectually normal. So far, 168 patients have been reported. Language is usually very limited. Seizures occur in about one third of the cases. While many patients are affectionate with their caregivers, some exhibit autistic-like behaviour. Patients present with facial hypotonia and a characteristic mouth. Genital abnormalities are observed in 80% of children and range from undescended testes to ambiguous genitalia. Alpha-thalassaemia is not always present. This syndrome is X-linked recessive and results from mutations in the ATRX gene. This gene encodes the widely expressed ATRX protein. ATRX mutations cause diverse changes in the pattern of DNA methylation at heterochromatic loci but it is not yet known whether this is responsible for the clinical phenotype. The diagnosis can be established by detection of alpha thalassaemia, identification of ATRX gene mutations, ATRX protein studies and X-inactivation studies. Genetic counselling can be offered to families. Management is multidisciplinary: young children must be carefully monitored for gastro-oesophageal reflux as it may cause death. A number of individuals with ATR-X are fit and well in their 30s and 40s.

    Full Text Available Sustainable Development Management. Our paper focuses on defining the concept of sustainable from a geographical point of view as it compulsory has a territorial connotation, a spatial one that is characteristic of any geographical study. As a result we started from the premises that its defining elements were territorial cohesion, environmental preservation, natural resources preservation, demographical optimum, economic development, and social harmony. As the development phenomenon is not a linear one, neither lacking convulsions nor contradictions, it supposes, in order to be sustainable, an appropriate management. This management includes the following main aspects: use of renewable resources, resources complementarity, optimum relationship between population and resources, tolerable anthropic pressure, harmonisation of request and offer relationship, resilience to climatic change and permanent dissipation of negative impact in nature and in society. The conclusion of our study points out the complexity of the phenomenon of sustainable development, and also the possibility of optimising it through permanent and inspired management.

    A wide spectrum of maturing methods and tools, collectively characterized as the Semantic Web, is helping to vastly improve the dissemination of scientific research. Creating semantic integration requires input from both domain and cyberinfrastructure scientists. OceanLink, an NSF EarthCube Building Block, is demonstrating semantic technologies through the integration of geoscience data repositories, library holdings, conference abstracts, and funded research awards. Meeting project objectives involves applying semantic technologies to support data representation, discovery, sharing and integration. Our semantic cyberinfrastructure components include ontology design patterns, Linked Data collections, semantic provenance, and associated services to enhance data and knowledge discovery, interoperation, and integration. We discuss how these components are integrated, the continued automated and semi-automated creation of semantic metadata, and techniques we have developed to integrate ontologies, link resources, and preserve provenance and attribution.

PEFP planned to supply 20MeV and 100MeV proton beam by the development of the 100MeV, 20mA linear accelerator during ten years from 2002 to 2012. The final goal of this project is establishment of 20MeV and 100MeV user facilities. To do this, we must develop the key technologies for establishing user facilities. Before the main facilities are normally operated, we have established the test user facilities to support various kinds of users' basic experiments and pilot studies. The necessity of this research are as follows; - Domestic achievement of key technologies for the development and design of the user facilities for the several tens to hundreds MeV class high current proton beam - Beam application researches can be revitalized and improved the efficiency by the establishment and operation of user facilities and test facilities. - Ion implantation facilities have contributed to increase Industrial applications - It is more effective in saving money that users use the PEFP's user facility than other country's user facilities. - It is possible to contribute to the local society and commercialize the beam application technologies by the establishment of PEFP's research branch in Kyungju

    Until now, because we have imported experimental animal from foreign experimental animal corporation, we could have saved money by establishing the quality control of animal in barrier system. In order to improve the quality of animal experiment and efficiency of biomedical study, it is indispensable to control many factors that effect in the experiment. Therefore, it is essential to organize the system of laboratory animal care for enhancing reliability and revivability of experimental results. The purpose of the present investigation was to establish the quality control system of experimental animals that we can provide good quality animals according to the experimental condition of each investigator although the exact quality control system to estimate the infection of bacteria and virus easily remains ill-defined yet. Accordingly, we established the useful quality control system for microbiologic monitoring and environmental monitoring to protect experimental animal from harmful bacteria and virus

    2012-09-30

    This project was directed at establishing a comprehensive wind energy program in Indiana, including both educational and research components. A graduate/undergraduate course ME-514 - Fundamentals of Wind Energy has been established and offered and an interactive prediction of VAWT performance developed. Vertical axis wind turbines for education and research have been acquired, instrumented and installed on the roof top of a building on the Calumet campus and at West Lafayette (Kepner Lab). Computational Fluid Dynamics (CFD) calculations have been performed to simulate these urban wind environments. Also, modal dynamic testing of the West Lafayette VAWT has been performed and a novel horizontal axis design initiated. The 50-meter meteorological tower data obtained at the Purdue Beck Agricultural Research Center have been analyzed and the Purdue Reconfigurable Micro Wind Farm established and simulations directed at the investigation of wind farm configurations initiated. The virtual wind turbine and wind turbine farm simulation in the Visualization Lab has been initiated.

    Medical application of radiation has gained wider study since diagnostic radiology plays a very important role in modern medicine. The need of the service seems to increase since the invention of digital radiology as a new technology that promises greater accuracy while minimizing patient dose. However, it is not exempted in the harmonization of doses delivered to the patient undergoing same radiologic examination in different institutions either regional or nationwide. The objective of this project was to review the establishment of Diagnostic Reference Levels (DRLs) in digital radiology at National level with the aim to reduce patient dose while maintaining appropriate image quality. A general discussion on digital radiology has been presented focusing on the optimization of patient dose as well as dosimetric quantities used for the establishment of DRLs. Recommendations have been provided for Rwanda to initiate steps to establish National Diagnostic Reference Levels for common procedures in digital radiology. (au)

    Nuclear data is fundamental data for development of new type of nuclear, upgrade of nuclear fuel, treatment of radwaste, research on fusion reactor, radioisotope usage, and nuclear medical therapy. Nuclear data is produced with experiments. However rack of experimental data for thousands of nuclides and various reaction types makes it essential to do statistical evaluation and theoretical interpolation. This study is intended to join international cooperation after establishing domestic basis for nuclear data evaluation work. This project is the first year of five year plan to do followings: 1) Establishment of database system to collect experimental data, 2) Setup of computer assistance system for evaluation work, 3) Verification of established system by test evaluation of selected nuclide reaction. The system has a collection of mass data of nuclides, computer codes for test evaluation of total cross section of 0-16 and collection of EXFOR format data for 0-16. This system will be improved continuously on next years. (Author)

    Craniopharynigoma samples were collected from 36 patients. Out of the 36 samples, 29 achieved successful sub-culturing, with a success rate of 80.6%. Immunohistochemistry staining showed that cytokeratin-7 was positively expressed in the cytomembrane and cytoplasm of craniopharyngioma cells at 6-8 passages, confirming that all cultured cells were squamous epithelial cells. The doubling time of craniopharyngioma cells was 3 days, as confirmed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. In this study, craniopharyngioma cells cultured in vitro were established; however, establishment of immortalized craniopharyngioma cell lines requires further research. PMID:25745451

At first this paper reviews the concept of tolerable soil loss and summarises the available definitions and the knowledge on the recommended values and evaluating criteria. Then a threshold soil loss value, at the annual temporal scale, established for limiting riling was used for defining the classical soil loss tolerance. Finally, some research needs on tolerable soil loss are listed.

  16. Simulation of Controller Pilot Data Link Communications over VHF Digital Link Mode 3

    Science.gov (United States)

    Bretmersky, Steven C.; Murawski, Robert; Nguyen, Thanh C.; Raghavan, Rajesh S.

    2004-01-01

    The Federal Aviation Administration (FAA) has established an operational plan for the future Air Traffic Management (ATM) system, in which the Controller Pilot Data Link Communications (CPDLC) is envisioned to evolve into digital messaging that will take on an ever increasing role in controller to pilot communications, significantly changing the way the National Airspace System (NAS) is operating. According to FAA, CPDLC represents the first phase of the transition from the current analog voice system to an International Civil Aviation Organization (ICAO) compliant system in which digital communication becomes the alternate and perhaps primary method of routine communication. The CPDLC application is an Air Traffic Service (ATS) application in which pilots and controllers exchange messages via an addressed data link. CPDLC includes a set of clearance, information, and request message elements that correspond to existing phraseology employed by current Air Traffic Control (ATC) procedures. These message elements encompass altitude assignments, crossing constraints, lateral deviations, route changes and clearances, speed assignments, radio frequency assignments, and various requests for information. The pilot is provided with the capability to respond to messages, to request clearances and information, to report information, and to declare/rescind an emergency. A 'free text' capability is also provided to exchange information not conforming to defined formats. This paper presents simulated results of the aeronautical telecommunication application Controller Pilot Data Link Communications over VHF Digital Link Mode 3 (VDL Mode 3). The objective of this simulation study was to determine the impact of CPDLC traffic loads, in terms of timely message delivery and capacity of the VDL Mode 3 subnetwork. The traffic model is based on and is used for generating air/ground messages with different priorities. Communication is modeled for the en route domain of the Cleveland

  17. Formaldehyde cross-linking and structural proteomics: Bridging the gap.

    Science.gov (United States)

    Srinivasa, Savita; Ding, Xuan; Kast, Juergen

    2015-11-01

    Proteins are dynamic entities constantly moving and altering their structures based on their functions and interactions inside and outside the cell. Formaldehyde cross-linking combined with mass spectrometry can accurately capture interactions of these rapidly changing biomolecules while maintaining their physiological surroundings. Even with its numerous established uses in biology and compatibility with mass spectrometry, formaldehyde has not yet been applied in structural proteomics. However, formaldehyde cross-linking is moving toward analyzing tertiary structure, which conventional cross-linkers have already accomplished. The purpose of this review is to describe the potential of formaldehyde cross-linking in structural proteomics by highlighting its applications, characteristics and current status in the field.

  1. Establishing rigour in qualitative radiography research

    Energy Technology Data Exchange (ETDEWEB)

    Murphy, F.J. [School of Healthcare Professions, University of Salford, Salford M6 6PU (United Kingdom)], E-mail: f.j.murphy@salford.ac.uk; Yielder, J. [Medical Imaging, School of Health Sciences, Unitec, Auckland (New Zealand)

    2010-02-15

    The vast majority of radiography research is subject to critique and evaluation from peers in order to justify the method and the outcome of the study. Within the quantitative domain, which the majority of medical imaging publications tend to fall into, there are prescribed methods for establishing scientific rigour and quality in order to critique a study. However, researchers within the qualitative paradigm, which is a developing area of radiography research, are often unclear about the most appropriate methods to measure the rigour (standards and quality) of a research study. This article considers the issues related to rigour, reliability and validity within qualitative research. The concepts of reliability and validity are briefly discussed within traditional positivism and then the attempts to use these terms as a measure of quality within qualitative research are explored. Alternative methods for research rigour in interpretive research (meanings and emotions) are suggested in order to compliment the existing radiography framework that exists for qualitative studies. The authors propose the use of an established model that is adapted to reflect the iterative process of qualitative research. Although a mechanistic approach to establishing rigour is rejected by many qualitative researchers, it is argued that a guide for novice researchers within a developing research base such as radiography is appropriate in order to establish the credibility and trustworthiness of a qualitative study.

However, researchers within the qualitative paradigm, which is a developing area of radiography research, are often unclear about the most appropriate methods to measure the rigour (standards and quality) of a research study. This article considers the issues related to rigour, reliability and validity within qualitative research. The concepts of reliability and validity are briefly discussed within traditional positivism and then the attempts to use these terms as a measure of quality within qualitative research are explored. Alternative methods for research rigour in interpretive research (meanings and emotions) are suggested in order to compliment the existing radiography framework that exists for qualitative studies. The authors propose the use of an established model that is adapted to reflect the iterative process of qualitative research. Although a mechanistic approach to establishing rigour is rejected by many qualitative researchers, it is argued that a guide for novice researchers within a developing research base such as radiography is appropriate in order to establish the credibility and trustworthiness of a qualitative study.

    Full Text Available Semantic Web technologies have redefined and strengthened the Enterprise-Web interoperability over the last decade. Linked Open Data (LOD refers to a set of best practices that empower enterprises to publish and interlink their data using existing ontologies on the World Wide Web. Current research in LOD focuses on expert search, the creation of unified information space and augmentation of core data from an enterprise context. However, existing approaches for publication of enterprise data as LOD are domain-specific, ad-hoc and suffer from lack of uniform representation across domains. The paper proposes a novel methodology called LinkED that contributes towards LOD literature in two ways: (a streamlines the publishing process through five stages of cleaning, triplification, interlinking, storage and visualization; (b addresses the latest challenges in LOD publication, namely: inadequate links, inconsistencies in the quality of the dataset and replicability of the LOD publication process. Further, the methodology is demonstrated via the publication of digital repository data as LOD in a university setting, which is evaluated based on two semantic standards: Five-Star model and data quality metrics. Overall, the paper provides a generic LOD publication process that is applicable across various domains such as healthcare, e-governance, banking, and tourism, to name a few.

  16. Establishment of human papillomavirus infection requires cell cycle progression.

    Full Text Available Human papillomaviruses (HPVs are DNA viruses associated with major human cancers. As such there is a strong interest in developing new means, such as vaccines and microbicides, to prevent HPV infections. Developing the latter requires a better understanding of the infectious life cycle of HPVs. The HPV infectious life cycle is closely linked to the differentiation state of the stratified epithelium it infects, with progeny virus only made in the terminally differentiating suprabasal compartment. It has long been recognized that HPV must first establish its infection within the basal layer of stratified epithelium, but why this is the case has not been understood. In part this restriction might reflect specificity of expression of entry receptors. However, this hypothesis could not fully explain the differentiation restriction of HPV infection, since many cell types can be infected with HPVs in monolayer cell culture. Here, we used chemical biology approaches to reveal that cell cycle progression through mitosis is critical for HPV infection. Using infectious HPV16 particles containing the intact viral genome, G1-synchronized human keratinocytes as hosts, and early viral gene expression as a readout for infection, we learned that the recipient cell must enter M phase (mitosis for HPV infection to take place. Late M phase inhibitors had no effect on infection, whereas G1, S, G2, and early M phase cell cycle inhibitors efficiently prevented infection. We conclude that host cells need to pass through early prophase for successful onset of transcription of the HPV encapsidated genes. These findings provide one reason why HPVs initially establish infections in the basal compartment of stratified epithelia. Only this compartment of the epithelium contains cells progressing through the cell cycle, and therefore it is only in these cells that HPVs can establish their infection. By defining a major condition for cell susceptibility to HPV infection, these

    Full Text Available Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases, vision deteriorates and can require corneal transplant surgery. Corneal collagen cross-linking (CCL with riboflavin (C3R is a recent treatment option that can enhance the rigidity of the cornea and prevent disease progression. Since its inception, the procedure has evolved with newer instrumentation, surgical techniques, and is also now performed for expanded indications other than keratoconus. With increasing experience, newer guidelines regarding optimization of patient selection, the spectrum of complications and their management, and combination procedures are being described. This article in conjunction with the others in this issue, will try and explore the uses of collagen cross-linking (CXL in its current form.

  19. Using turbocodes on optical links

    Full Text Available The fast evolving telecommunication world is permanently in search for faster and better communication links. On one hand, turbo codes are like a dream come true. Due to their amazing performance, they have become the reference in the word of error detecting and correcting codes. On the other hand, broadband transmission channels like optical fibres can meet the need for higher transmission velocity. In this paper therefore we will bring these two elements together and thus the performance of turbocodes on optical links will be studied. First the turbocode will be optimised throughout an individual analysis of each of its design parameters. Moreover it wil be shown that turbocodes have much better performance than the well known Reed-Solomon codes. Finally we will show that the 8Bit/10Bit code, which is required to comply with the Gigabit Ethernet standard, becomes superfluous when working with turbocodes. All tests were carried out on multimode graded-index glass fibres.
