  1. Spotlight: Ecuador.

    Science.gov (United States)

    1998-04-01

    This article describes the vital statistics and population growth in Ecuador as of mid-1997. Mid-1997 population numbered about 12 million. Fertility was 3.6 births/woman; deaths were 6/1000 population; and births were 29/1000 population. Ecuador was primarily an agricultural country, until oil was discovered in the early 1970s. The country has worked to increase per capita income and confront environmental consequences. The capital city of Quito is situated in a valley between two mountains and has very high air pollution levels due to cars and factories. In contrast, indigenous populations live in the Andean mountains and farm small plots. Land shortages have pushed these farmers onto higher slopes and more marginal land that is becoming eroded. 22% of Ecuador's forests were cleared for farming during 1980-90. The city of Guayaquil, on the Pacific coast, has serious water pollution problems, sewage problems, and industrial pollution. Shrimp farming relies on high levels of fertilizer, which is damaging coastlines. Oil exploration in the interior of Ecuador, has resulted in disruption of indigenous population, loss of forests, and pollution of rivers. Texaco Oil is accused of spilling about 17 million gallons of crude oil, or 50 times more than the Exxon Valdez oil spill in Alaska. Texaco argues that it met government environmental standards and agreed to a cleanup, which only partially meets the standards of its critics. Oil resources have funded improvements in education and health. About 90% of Ecuador's adult population is literate. Fertility has declined, but the population is still largely young and will be entering their reproductive years by 2025.

  2. Efficient sliding spotlight SAR raw signal simulation of extended scenes

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Abstract Sliding spotlight mode is a novel synthetic aperture radar (SAR imaging scheme with an achieved azimuth resolution better than stripmap mode and ground coverage larger than spotlight configuration. However, its raw signal simulation of extended scenes may not be efficiently implemented in the two-dimensional (2D Fourier transformed domain. This article presents a novel sliding spotlight raw signal simulation approach from the wide-beam SAR imaging modes. This approach can generate sliding spotlight raw signal not only from raw data evaluated by the simulators, but also from real data in the stripmap/spotlight mode. In order to obtain the desired raw data from conventional stripmap/spotlight mode, the azimuth time-varying filtering, which is implemented by de-rotation and low-pass filtering, is adopted. As raw signal of extended scenes in the stripmap/spotlight mode can efficiently be evaluated in the 2D Fourier domain, the proposed approach provides an efficient sliding spotlight SAR simulator of extended scenes. Simulation results validate this efficient simulator.

  13. Living in the spotlight

    CERN Multimedia

    2009-01-01

    Just a few weeks ago, we celebrated the 20th anniversary of the World Wide Web. It gave me my first opportunity since taking up my mandate to see first hand what CERN’s newfound public profile means in practice. There were over 60 media from around the world present at CERN for the event, and some 900 reports in the media over the following days. Some weeks before, Sony pictures held a press event for their upcoming movie, Angels and Demons, part of which takes place at CERN. That happened during the same week that we published the new LHC schedule, and it was the LHC that got the most media coverage. So what does this mean for how we carry out our daily work? Particle physics has always operated in a fully open and transparent way. It’s in our DNA to do so. Meetings are open to all comers, and it is important that we continue to foster such a culture of transparency. Nevertheless, we need to be aware that we are much more in the public spotlight than ever before....

  14. Remote Laser Diffraction PSD Analyzer

    Energy Technology Data Exchange (ETDEWEB)

    Batcheller, Thomas Aquinas; Huestis, Gary Michael; Bolton, Steven Michael

    2000-06-01

    Particle size distribution (PSD) analysis of radioactive slurry samples were obtained using a modified "off-the-shelf" classical laser light scattering particle size analyzer. A Horiba Instruments Inc. Model La-300 PSD analyzer, which has a 0.1 to 600 micron measurement range, was modified for remote application in a "hot cell" (gamma radiation) environment. The general details of the modifications to this analyzer are presented in this paper. This technology provides rapid and simple PSD analysis, especially down in the fine and microscopic particle size regime. Particle size analysis of these radioactive slurries down in this smaller range was not achievable - making this technology far superior than the traditional methods used previously. Remote deployment and utilization of this technology is in an exploratory stage. The risk of malfunction in this radiation environment is countered by gaining of this tremendously useful fundamental engineering data. Successful acquisition of this data, in conjunction with other characterization analyses, provides important information that can be used in the myriad of potential radioactive waste management alternatives.

  18. PSD-95 and PSD-93 Play Critical but Distinct Roles in Synaptic Scaling Up and Down

    Science.gov (United States)

    Sun, Qian; Turrigiano, Gina G.

    2011-01-01

    Synaptic scaling stabilizes neuronal firing through the homeostatic regulation of postsynaptic strength, but the mechanisms by which chronic changes in activity lead to bidirectional adjustments in synaptic AMPAR abundance are incompletely understood. Further, it remains unclear to what extent scaling up and scaling down utilize distinct molecular machinery. PSD-95 is a scaffold protein proposed to serve as a binding “slot” that determines synaptic AMPAR content, and synaptic PSD-95 abundance is regulated by activity, raising the possibility that activity-dependent changes in the synaptic abundance of PSD-95 or other MAGUKs drives the bidirectional changes in AMPAR accumulation during synaptic scaling. We found that synaptic PSD-95 and SAP102 (but not PSD-93) abundance were bidirectionally regulated by activity, but these changes were not sufficient to drive homeostatic changes in synaptic strength. Although not sufficient, the PSD-95-MAGUKs were necessary for synaptic scaling, but scaling up and down were differentially dependent on PSD-95 and PSD-93. Scaling down was completely blocked by reduced or enhanced PSD-95, through a mechanism that depended on the PDZ1/2 domains. In contrast scaling up could be supported by either PSD-95 or PSD-93 in a manner that depended on neuronal age, and was unaffected by a superabundance of PSD-95. Taken together, our data suggest that scaling up and down of quantal amplitude is not driven by changes in synaptic abundance of PSD-95-MAGUKs, but rather that the PSD-95 MAGUKs serve as critical synaptic organizers that utilize distinct protein-protein interactions to mediate homeostatic accumulation and loss of synaptic AMPAR.

  2. High-Accuracy Positioning of an Industrial Robot Using Image/PSD-Based Hybrid Servo Control

    Science.gov (United States)

    Liu, Yong; Xi, Ning; Shen, Yantao

    2011-04-01

    This article presents a new and effective multi-sensor-based control strategy for high-accuracy/precision and high-efficiency automatic robot positioning in the field of industrial robot calibration. The strategy combines both coarsely visual servo and fine position-sensitive detector (PSD) servo control methods. In a large field of view, an image-based visual servo control system is employed to roughly guide the laser spot, which is from a single laser pointer attached to the end-effector of a robot to project to the segmented PSDs with a resolution of better than 0.1 µm. Once the laser spot is projected onto the active area of the PSD surface, the control will automatically be switched to the PSD feedback and servoing for fine positioning. An image/PSD-based servoing system has been presented. Based on the system, the controller design and switch logic of the hybrid servoing are given. The experimental results conducted on an ABB industrial robot IRB1600 verified the effectiveness of the developed visual/PSD hybrid servo controllers, as well as demonstrated that the high accuracy of 30 µm of robot positioning can be approached. The development of the hybrid control method and system has played a major role in achieving high-performance automatic robot calibration.

    1991-12-01

    This report describes Welch's method for computing Power Spectral Densities (PSDs). We first describe the bandpass filter method which uses filtering, squaring, and averaging operations to estimate a PSD. Second, we delineate the relationship of Welch's method to the bandpass filter method. Third, the frequency domain signal-to-noise ratio for a sine wave in white noise is derived. This derivation includes the computation of the noise floor due to quantization noise. The signal-to-noise ratio and noise flood depend on the FFT length and window. Fourth, the variance the Welch's PSD is discussed via chi-square random variables and degrees of freedom. This report contains many examples, figures and tables to illustrate the concepts. 26 refs.

  13. Sliding Spotlight Mode Imaging with GF-3 Spaceborne SAR Sensor

    Directory of Open Access Journals (Sweden)

    Qingjun Zhang

    2017-12-01

    Full Text Available Synthetic aperture radar (SAR sliding spotlight work mode can achieve high resolutions and wide swath (HRWS simultaneously by steering the radar antenna beam. This paper aims to obtain well focused images using sliding spotlight mode with the Chinese Gaofen-3 SAR sensor. We proposed an integrated imaging scheme with sliding spotlight echoes. In the imaging scheme, the two-step approach is applied to the spaceborne sliding spotlight SAR imaging algorithm, followed by the Doppler parameter estimation algorithm. The azimuth spectral folding phenomenon is overcome by the two-step approach. The results demonstrate a high Doppler parameter estimation accuracy. The proposed imaging process is accurate and highly efficient for sliding spotlight SAR mode.

    Ryu, Young Kee; Oh, Choonsuk

    2007-10-01

    This paper describes a monocular PSD-based motion capture sensor to employ with commercial video game systems such as Microsoft's XBOX and Sony's Playstation II. The system is compact, low-cost, and only requires a one-time calibration at the factory. The system includes a PSD(Position Sensitive Detector) and active infrared (IR) LED markers that are placed on the object to be tracked. The PSD sensor is placed in the focal plane of a wide-angle lens. The micro-controller calculates the 3D position of the markers using only the measured intensity and the 2D position on the PSD. A series of experiments were performed to evaluate the performance of our prototype system. From the experimental results we see that the proposed system has the advantages of the compact size, the low cost, the easy installation, and the high frame rates to be suitable for high speed motion tracking in games.

  19. Scientist Spotlight Homework Assignments Shift Students' Stereotypes of Scientists and Enhance Science Identity in a Diverse Introductory Science Class.

    Science.gov (United States)

    Schinske, Jeffrey N; Perkins, Heather; Snyder, Amanda; Wyer, Mary

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments ("Scientist Spotlights") that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms. © 2016 J.

    2015-01-01

    There is a need to derive a power spectral density (PSD) envelope for nonstationary acceleration time histories, including launch vehicle data, so that components can be designed and tested accordingly. This paper presents the results of the three methods for an actual flight accelerometer record. Guidelines are given for the application of each method to nonstationary data. The method can be extended to other scenarios, including transportation vibration.

    The formation and stabilization of new dendritic spines is a key component of the experience-dependent neural circuit plasticity that supports learning, but the molecular maturation of nascent spines remains largely unexplored. The PSD95-family of membrane-associated guanylate kinases (PSD-MAGUKs), most notably PSD95, has a demonstrated role in promoting spine stability. However, nascent spines contain low levels of PSD95, suggesting that other members of the PSD-MAGUK family might act to stabilize nascent spines in the early stages of spiny synapse formation. Here, we used GFP-fusion constructs to quantitatively define the molecular composition of new spines, focusing on the PSD-MAGUK family. We found that PSD95 levels in new spines were as low as those previously associated with rapid subsequent spine elimination, and new spines did not achieve mature levels of PSD95 until between 12 and 20 h following new spine identification. Surprisingly, we found that the PSD-MAGUKs PSD93, SAP97, and SAP102 were also substantially less enriched in new spines. However, they accumulated in new spines more quickly than PSD95: SAP102 enriched to mature levels within 3 h, SAP97 and PSD93 enriched gradually over the course of 6 h. Intriguingly, when we restricted our analysis to only those new spines that persisted, SAP97 was the only PSD-MAGUK already present at mature levels in persistent new spines when first identified. Our findings uncover a key structural difference between nascent and mature spines, and suggest a mechanism for the stabilization of nascent spines through the sequential arrival of PSD-MAGUKs. © 2017 Wiley Periodicals, Inc.

  10. PSD-Constrained PAR Reduction for DMT/OFDM

    Andgart, Niklas; Krongold, Brian S.; Ödling, Per; Johansson, Albin; Börjesson, Per Ola

    2004-12-01

    Common to all DMT/OFDM systems is a large peak-to-average ratio (PAR), which can lead to low power efficiency and nonlinear distortion. Tone reservation uses unused or reserved tones to design a peak-canceling signal to lower the PAR of a transmit block. In DMT ADSL systems, the power allocated to these tones may be limited due to crosstalk issues with many users in one twisted pair bundle. This PSD limitation not only limits PAR reduction ability, but also makes the optimization problem more challenging to solve. Extending the recently proposed active set tone reservation method, we develop an efficient algorithm with performance close to the optimal solution.

    2015-12-15

    Phosphatidylethanolamine (PE) in the yeast Saccharomyces cerevisiae is synthesized through decarboxylation of phosphatidylserine (PS), catalysed by PS decarboxylase 1 (Psd1p) and 2 (Psd2p) and the cytidine 5'-diphosphate (CDP)-ethanolamine (CDP-Etn) pathway. PSD1 null (psd1Δ) and PSD2 null (psd2Δ) mutants are viable in a synthetic minimal medium, but a psdpsd2Δ double mutant exhibits Etn auxotrophy, which is incorporated into PE through the CDP-Etn pathway. We have previously shown that psd1Δ is synthetic lethal with deletion of VID22 (vid22Δ) [Kuroda et al. (2011) Mol. Microbiol. 80: , 248-265]. In the present study, we found that vid22Δ mutant exhibits Etn auxotrophy under PSD1-depressed conditions. Deletion of VID22 in wild-type and PSD1-depressed cells caused partial defects in PE formation through decarboxylation of PS. The enzyme activity of PS decarboxylase in an extract of vid22Δ cells was ∼70% of that in wild-type cells and similar to that in psd2Δ cells and the PS decarboxylase activity remaining in the PSD1-depressed cells became almost negligible with deletion of VID22. Thus, the vid22Δ mutation was suggested to cause a defect in the Psd2p activity. Furthermore, vid22Δ cells were shown to be defective in expression of the PSD2 gene tagged with 6×HA, the defect being ameliorated by replacement of the native promoter of the PSD2 gene with a CYC1 promoter. In addition, an α-galactosidase reporter assay revealed that the activity of the promoter of the PSD2 gene in vid22Δ cells was ∼5% of that in wild-type cells. These results showed that VID22 is required for transcriptional activation of the PSD2 gene. © 2015 Authors; published by Portland Press Limited.

    This report presents results and analysis from a series of proof-of-concept measurements to assess the suitability of segmented detectors constructed from Eljen EJ-299-34 PSD-plastic scintillator with pulse-shape discrimination capability for the purposes of quantifying uranium via active neutron coincidence counting. Present quantification of bulk uranium materials for international safeguards and domestic materials control and accounting relies on active neutron coincidence counting systems, such as the Active Well Coincidence Counter (AWCC) and the Uranium Neutron Coincidence Collar (UNCL), that use moderated He-3 proportional counters along with necessarily low-intensity 241Am(Li) neutron sources. Scintillation-based fast-neutron detectors are a potentially superior technology to the existing AWCC and UNCL designs due to their spectroscopic capability and their inherently short neutron coincidence times that largely eliminate random coincidences and enable interrogation by stronger sources. One of the past impediments to the investigation and adoption of scintillation counters for the purpose of quantifying bulk uranium was the commercial availability of scintillators having the necessary neutron-gamma pulse-shape discrimination properties only as flammable liquids. Recently, Eljen EJ-299-34 PSD-plastic scintillator became commercially available. The present work is the first assessment of an array of PSD-plastic detectors for the purposes of quantifying bulk uranium. The detector panel used in the present work was originally built as the focal plane for a fast-neutron imager, but it was repurposed for the present investigation by construction of a stand to support the inner well of an AWCC immediately in front of the detector panel. The detector panel and data acquisition of this system are particularly well suited for performing active-well fast-neutron counting of LEU and HEU samples because the active detector volume is solid, the 241Am(Li) interrogating

    Wereport a small angle neutron scattering study of the thermodynamics of a polymer mixture in the presence of nanoparticles, both in equilibrium and during phase separation. Neutron cloud point measurements and random phase approximation (RPA) analysis demonstrate that 1-2 mass % of C60 fullerenes destabilizes a highly interacting mixture of poly(tetramethyl bisphenol A polycarbonate) and deuterated polystyrene (TMPC/PSd). We unequivocally corroborate these findings with time-resolved temperature jump experiments that, in identical conditions, result in phase separation for the nanocomposite and stability for the neat polymer mixture. At lower C 60 loadings (viz. 0.2-0.5 mass %), stabilization of the mixture is observed. The nonmonotonic variation of the spinodal temperature with fullerene addition suggests a competitive interplay of asymmetric component interactions and nanoparticle dispersion. The stability line shift depends critically on particle dispersion and vanishes upon nanoparticle agglomeration. © 2010 American Chemical Society.

  7. Practical Findings from Applying the PSD Model for Evaluating Software Design Specifications

    Räisänen, Teppo; Lehto, Tuomas; Oinas-Kukkonen, Harri

    This paper presents practical findings from applying the PSD model to evaluating the support for persuasive features in software design specifications for a mobile Internet device. On the one hand, our experiences suggest that the PSD model fits relatively well for evaluating design specifications. On the other hand, the model would benefit from more specific heuristics for evaluating each technique to avoid unnecessary subjectivity. Better distinction between the design principles in the social support category would also make the model easier to use. Practitioners who have no theoretical background can apply the PSD model to increase the persuasiveness of the systems they design. The greatest benefit of the PSD model for researchers designing new systems may be achieved when it is applied together with a sound theory, such as the Elaboration Likelihood Model. Using the ELM together with the PSD model, one may increase the chances for attitude change.

    Understanding biological processes at the mechanistic level requires a systematic charting of the physical and functional links between all cellular components. While protein-protein and protein-nucleic acid networks have been subject to many global surveys, other critical cellular components such as membrane lipids have rarely been studied in large-scale interaction screens. Here, we review the development of photoactivatable and clickable lipid analogues-so-called bifunctional lipids-as novel chemical tools that enable a global profiling of lipid-protein interactions in biological membranes. Recent studies indicate that bifunctional lipids hold great promise in systematic efforts to dissect the elaborate crosstalk between proteins and lipids in live cells and organisms.

    Directory of Open Access Journals (Sweden)

    Dan O’SULLIVAN

    2015-12-01

    Full Text Available As qualitative research undertakings are not independent of the researcher, the “indissoluble interrelationship between interpreter and interpretation” (Thomas & James, 2006, p. 782 renders it necessary for researchers to understand that their text is a representation, a version of the truth that is the product of writerly choices, and that it is discursive. Endlessly creative, artistic and political, as there is no single interpretative truth, the interpretative process facilitates the refashioning of representations, the remaking of choices and the probing of discourses. As a consequence of the particularity of any researcher’s account, issues pertaining to researcher identity and authorial stance always remain central to research endeavours (Kamler & Thomson, 2006, p. 68; Denzin & Lincoln 2011, pp. 14-15. Therefore, researchers are encouraged to be reflexive about their analyses and research accounts (Elliott, 2005, p. 152, as reflexivity helps spotlight the role of the researcher as narrator. In turn, spotlighting the researcher as narrator foregrounds a range of complex issues about voice, representation and interpretive authority (Chase, 2005, p. 657; Genishi & Glupczynski, 2006, p. 671; Eisenhart, 2006. In essence, therefore, this paper is reflective of the challenges of “doing” qualitative research in educational settings. Its particular focus-the shaping of beginning primary teachers’ identities, in Ireland, throughout the course of their initial year of occupational experience, post-graduation- endeavours to highlight issues pertaining to the researcher as narrator (O’Sullivan, 2014.

    2011-01-01

    We extend the program initiated by T. Werlang et al. [Phys. Rev. Lett. 105, 095702 (2010)] in several directions. Firstly, we investigate how useful quantum correlations, such as entanglement and quantum discord, are in the detection of critical points of quantum phase transitions when the system is at finite temperatures. For that purpose we study several thermalized spin models in the thermodynamic limit, namely, the XXZ model, the XY model, and the Ising model, all of which with an external magnetic field. We compare the ability of quantum discord, entanglement, and some thermodynamic quantities to spotlight the quantum critical points for several different temperatures. Secondly, for some models we go beyond nearest neighbors and also study the behavior of entanglement and quantum discord for second nearest neighbors around the critical point at finite temperature. Finally, we furnish a more quantitative description of how good all these quantities are in spotlighting critical points of quantum phase transitions at finite T, bridging the gap between experimental data and those theoretical descriptions solely based on the unattainable absolute zero assumption.

    2016-04-01

    Full Text Available Vibration at the pedal-pad may contribute to discomfort of foot plantar fascia during driving. This is due to transmission of vibration to the mount, chassis, pedal, and then to the foot plantar fascia. This experimental study is conducted to determine the estimation of peak value using the power spectral density of the vertical vibration input at the foot. The power spectral density value is calculated based on the frequency range between 13 Hz to 18 Hz. This experiment was conducted using 12 subjects testing on three size of pedal-pads; small, medium and large. The result shows that peak value occurs at resonance frequency of 15 Hz. The PSD values at that resonance frequency are 0.251 (m/s2 2/Hz for small pedal-pad, followed by the medium pedal-pad is at 0.387 (m/s2 2/Hz and lastly for the large pedal-pad is at 0.483 (m/s22/Hz. The resultsindicate that during driving, the foot vibration when interact with the large pedal-pad contributed higher stimulus compared with the small and medium pedal-pad. The pedal-pad size plays an important role in the pedal element designs in terms of vibration-transfer from pedal-pads on the feet, particularly to provide comfort to the driver while driving.

    2001-08-01

    Frequency scaling approach is a new spotlight SAR image formation algorithm. It precisely performs the range cell migration correction for dechirped raw data without interpolation by using a novel frequency scaling operation while residual video phase is corrected simultaneously. The computation requirements are lower than the other spotlight SAR image formation approaches such as polar format algorithm and range migration algorithm. In this paper, frequency scaling algorithm is applied to process high squint spotlight data. The new squint illumination geometry is defined and some modifications to the basic algorithm are presented. Point target simulations up to 45 deg squint angle are carried out to show the validity of the algorithm.

    2013-10-01

    According to the principle of centroid measurement, position-sensitive detectors (PSD) are commonly used for micro displacement detection. However, single-beam detection method cannot satisfy such tasks as multi-dimension position measurement, three dimension vision reconstruction, and robot precision positioning, which require synchronous measurement of multiple light beams. Consequently, we designed PSD phase detection method using frequency-domain multiplexing for synchronous detection of multiple modulated light beams. Compared to previous PSD amplitude detection method, the phase detection method using FDM has advantages of simplified measuring system, low cost, high capability of resistance to light interference as well as improved resolution. The feasibility of multi-beam synchronous measurement based on PSD phase detection using FDM was validated by multi-beam measuring experiments. The maximum non-linearity error of the multi-beam synchronous measurement is 6.62%.

    The production of biocontrol factors by Pseudomonads is reported to be controlled at the post-transcriptional level by the GacS/GacA signal transduction pathway. This involves RNA-binding translational repressor proteins, RsmA and RsmE, and the small regulatory RNAs (sRNAs) RsmX, RsmY, and RsmZ. While the former represses genes involved in secondary metabolite production, the latter relieves this repression at the end of exponential growth. We have studied the fluorescent Pseudomonas strain Psd, possessing good biocontrol potential, and confirmed the presence of rsmY and rsmZ by PCR amplification. Gene constructs for all the three small RNAs (RsmX, RsmY and RsmZ) carried on broad host-range plasmid, pME6032 were mobilized into strain Psd. Expression analysis of gacA in the recombinant strains over-expressing rsmX (Psd-pME7320), rsmY (Psd-pME6359) and rsmZ (Psd-pME6918) revealed a significant upregulation of the response regulator. Besides, a remarkable down-regulation of rsmA was also reported in all the strains. The variant strains were found to produce comparatively higher levels of phenazines. Indole acetic acid levels were higher to some extent, and strain Psd-pME6918 also showed elevated production of HCN. The tomato seedlings infected with Fusarium oxysporum and Verticillium dahliae in the presence of culture filtrate of the recombinant strains showed better plant protection response in comparison to the wild-type strain Psd. These results suggest that small RNAs are important determinants in regulation of the biocontrol property of strain Psd. Copyright © 2016 Elsevier GmbH. All rights reserved.

    The DArk Matter Particle Explorer (DAMPE) is a high-resolution multi-purpose space-borne device for detecting the high-energy cosmic-rays like e±, γ-rays, protons, and heavy-ions, which was launched on 2015 December 17th. The Plastic Scintillator Detector (PSD) is the top-most sub-detector of DAMPE. The PSD is designed to measure the charge of incident high-energy particles, and to serve as a veto detector for discriminating γ-rays from the charged particles. In this paper, the on-orbit status of the PSD after launching in terms of high voltage (HV) and temperature stabilities is presented. The temperature and the HV variations of the PSD are less than 1°C and 0.5%, respectively. By using the on-orbit data, the attenuation lengths of PSD bars are obtained according to an empirical formula. A preliminary charge spectrum reconstructed from the X-layer of the PSD is obtained.

    1992-01-01

    Convolution backprojection (CBP) image reconstruction has been proposed as a means of producing high-resolution synthetic-aperture radar (SAR) images by processing data directly in the polar recording format which is the conventional recording format for spotlight mode SAR. The CBP algorithm filters each projection as it is recorded and then backprojects the ensemble of filtered projections to create the final image in a pixel-by-pixel format. CBP reconstruction produces high-quality images by handling the recorded data directly in polar format. The CBP algorithm requires only 1-D interpolation along the filtered projections to determine the precise values that must be contributed to the backprojection summation from each projection. The algorithm is thus able to produce higher quality images by eliminating the inaccuracies of 2-D interpolation, as well as using all the data recorded in the spectral domain annular sector more effectively. The computational complexity of the CBP algorithm is O(N (3)).

    2015-06-01

    Full Text Available In this paper, a method of using a one-dimensional position-sensitive detector (PSD by replacing charge-coupled device (CCD to measure the movement of the interference fringes is presented first, and its feasibility is demonstrated through an experimental setup based on the principle of centroid detection. Firstly, the centroid position of the interference fringes in a fiber Mach-Zehnder (M-Z interferometer is solved in theory, showing it has a higher resolution and sensitivity. According to the physical characteristics and principles of PSD, a simulation of the interference fringe’s phase difference in fiber M-Z interferometers and PSD output is carried out. Comparing the simulation results with the relationship between phase differences and centroid positions in fiber M-Z interferometers, the conclusion that the output of interference fringes by PSD is still the centroid position is obtained. Based on massive measurements, the best resolution of the system is achieved with 5.15, 625 μm. Finally, the detection system is evaluated through setup error analysis and an ultra-narrow-band filter structure. The filter structure is configured with a one-dimensional photonic crystal containing positive and negative refraction material, which can eliminate background light in the PSD detection experiment. This detection system has a simple structure, good stability, high precision and easily performs remote measurements, which makes it potentially useful in material small deformation tests, refractivity measurements of optical media and optical wave front detection.

    Puffy skin disease (PSD) is a disease that causes skin pathology in rainbow trout, Oncorhynchus mykiss (Walbaum). Incidence of PSD in UK fish farms and fisheries has increased sharply in the last decade, with growing concern from both industry sectors. This paper provides the first comprehensive case definition of PSD, combining clinical and pathological observations of diseased rainbow trout from both fish farms and fisheries. The defining features of PSD, as summarized in the case definition, were focal lateral flank skin lesions that appeared as cutaneous swelling with pigment loss and petechiae. These were associated with lethargy, poor body condition, inappetance and low level mortality. Epidermal hyperplasia and spongiosis, oedema of the dermis stratum spongiosum and a mild diffuse inflammatory cellularity were typical in histopathology of skin. A specific pathogen or aetiology was not identified. Prevalence and severity of skin lesions was greatest during late summer and autumn, with the highest prevalence being 95%. Atypical lesions seen in winter and spring were suggestive of clinical resolution. PSD holds important implications for both trout aquaculture and still water trout fisheries. This case definition will aid future diagnosis, help avoid confusion with other skin conditions and promote prompt and consistent reporting. © 2014 John Wiley & Sons Ltd.

    Aberrant increases in NMDA receptor (NMDAR) signaling contributes to central nervous system sensitization and chronic pain by activating neuronal nitric oxide synthase (nNOS) and generating nitric oxide (NO). Because the scaffolding protein postsynaptic density 95kDA (PSD95) tethers nNOS to NMDARs, the PSD95-nNOS complex represents a therapeutic target. Small molecule inhibitors IC87201 (EC5O: 23.94 µM) and ZL006 (EC50: 12.88 µM) directly inhibited binding of purified PSD95 and nNOS proteins in AlphaScreen without altering binding of PSD95 to ErbB4. Both PSD95-nNOS inhibitors suppressed glutamate-induced cell death with efficacy comparable to MK-801. IC87201 and ZL006 preferentially suppressed phase 2A pain behavior in the formalin test and suppressed allodynia induced by intraplantar complete Freund’s adjuvant administration. IC87201 and ZL006 suppressed mechanical and cold allodynia induced by the chemotherapeutic agent paclitaxel (ED50s: 2.47 and 0.93 mg/kg i.p. for IC87201 and ZL006, respectively). Efficacy of PSD95-nNOS disruptors was similar to MK-801. Motor ataxic effects were induced by MK-801 but not by ZL006 or IC87201. Finally, MK-801 produced hyperalgesia in the tail-flick test whereas IC87201 and ZL006 did not alter basal nociceptive thresholds. Our studies establish the utility of using AlphaScreen and purified protein pairs to establish and quantify disruption of protein-protein interactions. Our results demonstrate previously unrecognized antinociceptive efficacy of ZL006 and establish, using two small molecules, a broad application for PSD95-nNOS inhibitors in treating neuropathic and inflammatory pain. Collectively, our results demonstrate that disrupting PSD95-nNOS protein-protein interactions is effective in attenuating pathological pain without producing unwanted side effects (i.e. motor ataxia) associated with NMDAR antagonists.

  6. Impairment of TrkB-PSD-95 signaling in Angelman syndrome.

    Directory of Open Access Journals (Sweden)

    Cong Cao

    Full Text Available Angelman syndrome (AS is a neurodevelopment disorder characterized by severe cognitive impairment and a high rate of autism. AS is caused by disrupted neuronal expression of the maternally inherited Ube3A ubiquitin protein ligase, required for the proteasomal degradation of proteins implicated in synaptic plasticity, such as the activity-regulated cytoskeletal-associated protein (Arc/Arg3.1. Mice deficient in maternal Ube3A express elevated levels of Arc in response to synaptic activity, which coincides with severely impaired long-term potentiation (LTP in the hippocampus and deficits in learning behaviors. In this study, we sought to test whether elevated levels of Arc interfere with brain-derived neurotrophic factor (BDNF TrkB receptor signaling, which is known to be essential for both the induction and maintenance of LTP. We report that TrkB signaling in the AS mouse is defective, and show that reduction of Arc expression to control levels rescues the signaling deficits. Moreover, the association of the postsynaptic density protein PSD-95 with TrkB is critical for intact BDNF signaling, and elevated levels of Arc were found to impede PSD-95/TrkB association. In Ube3A deficient mice, the BDNF-induced recruitment of PSD-95, as well as PLCγ and Grb2-associated binder 1 (Gab1 with TrkB receptors was attenuated, resulting in reduced activation of PLCγ-α-calcium/calmodulin-dependent protein kinase II (CaMKII and PI3K-Akt, but leaving the extracellular signal-regulated kinase (Erk pathway intact. A bridged cyclic peptide (CN2097, shown by nuclear magnetic resonance (NMR studies to uniquely bind the PDZ1 domain of PSD-95 with high affinity, decreased the interaction of Arc with PSD-95 to restore BDNF-induced TrkB/PSD-95 complex formation, signaling, and facilitate the induction of LTP in AS mice. We propose that the failure of TrkB receptor signaling at synapses in AS is directly linked to elevated levels of Arc associated with PSD-95 and PSD-95

    Here, we propose a mathematical model and a calibration procedure for a PSD (position sensitive device) sensor equipped with an optical system, to enable accurate measurement of the angle of arrival of one or more beams of light emitted by infrared (IR) transmitters located at distances of between 4 and 6 m. To achieve this objective, it was necessary to characterize the intrinsic parameters that model the system and obtain their values. This first approach was based on a pin-hole model, to which system nonlinearities were added, and this was used to model the points obtained with the nA currents provided by the PSD. In addition, we analyzed the main sources of error, including PSD sensor signal noise, gain factor imbalances and PSD sensor distortion. The results indicated that the proposed model and method provided satisfactory calibration and yielded precise parameter values, enabling accurate measurement of the angle of arrival with a low degree of error, as evidenced by the experimental results.

  13. D-serine and serine racemase are associated with PSD-95 and glutamatergic synapse stability

    Directory of Open Access Journals (Sweden)

    Hong eLin

    2016-02-01

    Full Text Available D-serine is an endogenous coagonist at the glycine site of synaptic NMDA receptors (NMDARs, synthesized by serine racemase (SR through conversion of L-serine. It is crucial for synaptic plasticity and is implicated in schizophrenia. Our previous studies demonstrated specific loss of SR, D-serine-responsive synaptic NMDARs, and glutamatergic synapses in cortical neurons lacking alpha7 nicotinic acetylcholine receptors, which promotes glutamatergic synapse formation and maturation during development. We thus hypothesize that D-serine and SR (D-serine/SR are associated with glutamatergic synaptic development. Using morphological and molecular studies in cortical neuronal cultures, we demonstrate that D-serine/SR are associated with PSD-95 and NMDARs in postsynaptic neurons and with glutamatergic synapse stability during synaptic development. Endogenous D-serine and SR colocalize with PSD-95, but not presynaptic vesicular glutamate transporter 1 (VGLUT1, in glutamatergic synapses of cultured cortical neurons. Low-density astrocytes in cortical neuronal cultures lack SR expression but contain enriched D-serine in large vesicle-like structures, suggesting possible synthesis of D-serine in postsynaptic neurons and storage in astrocytes. More interestingly, endogenous D-serine and SR colocalize with PSD-95 in the postsynaptic terminals of glutamatergic synapses during early and late synaptic development, implicating involvement of D-serine/SR in glutamatergic synaptic development. Exogenous application of D-serine enhances the interactions of SR with PSD-95 and NR1, and increases the number of VGLUT1- and PSD-95-positive glutamatergic synapses, suggesting that exogenous D-serine enhances postsynaptic SR/PSD-95 signaling and stabilizes glutamatergic synapses during cortical synaptic development. This is blocked by NMDAR antagonist 2-amino-5-phosphonopentanoic acid (AP5 and 7-chlorokynurenic acid (7-CK, a specific antagonist at the glycine site of NMDARs

  14. Numerical simulation and analysis of fuzzy PID and PSD control methodologies as dynamic energy efficiency measures

    International Nuclear Information System (INIS)

    2004-01-01

    Energy efficiency enhancement is achieved by utilizing control algorithms that reduce overshoots and undershoots as well as unnecessary fluctuations in the amount of energy input to energy consuming systems during transient operation periods. It is hypothesized that application of control methodologies with characteristics that change with time and according to the system dynamics, identified as dynamic energy efficiency measures (DEEM), achieves the desired enhancement. The objective of this study is to simulate and analyze the effects of fuzzy logic based tuning of proportional integral derivative (F-PID) and proportional sum derivative (F-PSD) controllers for a heating and cooling energy system while accounting for the dynamics of the major system components. The procedure to achieve the objective includes utilization of fuzzy logic rules to determine the PID and PSD controllers gain coefficients so that the control laws for regulating the heat exchangers heating or cooling energy inputs are determined in each time step of the operation period. The performances of the F-PID and F-PSD controllers are measured by means of two cost functions that are based on quadratic forms of the energy input and deviation from a set point temperature. It is found that application of the F-PID control algorithm, as a DEEM, results in lower costs for energy input and deviation from a set point temperature by 24% and 17% as compared to a PID and 13% and 8% as compared to a PSD, respectively. It is also shown that the F-PSD performance is better than that of the F-PID controller

  15. Plastic Bonded Explosive (PBX) Particle Size Distribution (PSD) Measurements Using an Image Analysis System

    Energy Technology Data Exchange (ETDEWEB)

    Sullivan, Gregg K. [Univ. of Wyoming, Laramie, WY (United States)

    2003-06-01

    The slurry process for producing plastic bonded explosives (PBX) has been used for many years. However, until recently the mechanisms involved have not been studied quantitatively to determine the effects of the various control variables. Recently, the effects of operating variables on the final product have been studied; however, no attempt was made to measure particle growth during the slurry process. This study applies an image analysis tool to measure particle size distributions (PSDs) during the slurry process to produce PBX 9501, a specific formulation used in nuclear weapons. The observed PBX 9501 slurry behavior leads away from the typical population balance description of agglomeration, that is, a discrete particle-particle coalescence mechanism. The behavior observed in these experiments indicates that the initial state of the system contains a number of smaller particles clustered together. The cluster then coalesces into a large particle as solvent is removed and the slurry continuously mixed. Other small fragments are picked up and a relatively small amount of growth is observed. A mass transfer model adequately describes solvent removal, and an empirical model is developed to describe the growth behavior in terms of measured process variables. The image system is applied to dried molding powders. The PSD measurement results of the PBX 9501 library lots, historic samples set aside as PBX 9501 lots were accepted from the manufacturer, are also discussed and analyzed. A correlation analysis was conducted to find relationships between the measured PSD and other properties such as bulk density and pressed densities. While no significant correlation was found between the measured PSD and averaged bulk densities for the library lots, significant correlations are found between the measured PSD and pressed density. The final part of the study was to scale-up the PSD measurement capability. Since the large-scale processes are not yet operational, this work

    Full Text Available ABSTRACT“This one is stronger.” Spotlights on the lifelong learning professional-in-action Around the world, lifelong learning is being promoted as a strategy for coping with the changing realities of life and work. The fourth Sustainable Development Goal, agreed in September 2015, reflects this: “ensure equitable and inclusive quality education and promote lifelong learning opportunities for all”. Despite its importance, doubts remain about the implementation of this goal in practice (Van der Kamp, 2000; Regmi, 2015. This article looks at the practice of lifelong learning from the point of view of the professionals involved, their actions and the way these actions are challenged, supported and further developed. Following Schön’s “reflection-in-action” (1983, the term “professional-in-action” is used to stress the role of the professional in making the difference on the ground. The leading question is: how can lifelong learning professionals be supported in their contribution to surrounding society and its citizens? The professionals-in-action featured in this article include professionals based in the Netherlands as well as in other, less privileged contexts. Meaningful experiences are used to build a story about challenges, the right to exist, commitment, recognition and room to manoeuvre. The experiences reveal the importance of interacting with the learner and the professional space that is necessary to achieve this. Professionalization in professional learning communities and practice-oriented research must accompany this professional space. SAMENVATTING“Deze is sterker”. Spotlights op de leven lang leren professional-in-actieOm te kunnen omgaan met de veranderende realiteit in leven en werk, wordt wereldwijd een leven lang leren aangemoedigd. Het vierde duurzame ontwikkelingsdoel, vastgesteld in september 2015, weerspiegelt dit: “het verzekeren van kwalitatief goed onderwijs en het bevorderen van de mogelijkheden

    NASA Marshall Space Flight Center's Propulsion Systems Department (PSD) is four months into a fifteen month Knowledge Management (KM) initiative to support enhanced engineering decision making and analyses, faster resolution of anomalies (near-term) and effective, efficient knowledge infused engineering processes, reduced knowledge attrition, and reduced anomaly occurrences (long-term). The near-term objective of this initiative is developing a KM Pilot project, within the context of a 3-5 year KM strategy, to introduce and evaluate the use of KM within PSD. An internal NASA/MSFC PSD KM team was established early in project formulation to maintain a practitioner, user-centric focus throughout the conceptual development, planning and deployment of KM technologies and capabilities within the PSD. The PSD internal team is supported by the University of Alabama's Aging Infrastructure Systems Center of Excellence (AISCE), lntergraph Corporation, and The Knowledge Institute. The principle product of the initial four month effort has been strategic planning of PSD KNI implementation by first determining the "as is" state of KM capabilities and developing, planning and documenting the roadmap to achieve the desired "to be" state. Activities undertaken to suppoth e planning phase have included data gathering; cultural surveys, group work-sessions, interviews, documentation review, and independent research. Assessments and analyses have beon pedormed including industry benchmarking, related local and Agency initiatives, specific tools and techniques used and strategies for leveraging existing resources, people and technology to achieve common KM goals. Key findings captured in the PSD KM Strategic Plan include the system vision, purpose, stakeholders, prioritized strategic objectives mapped to the top ten practitioner needs and analysis of current resource usage. Opportunities identified from research, analyses, cultural1KM surveys and practitioner interviews include

    Although the discrete Fourier transform (DFT) based pulse shape discrimination (PSD) method, realized by transforming the digitized scintillation pulses into frequency coefficients by using DFT, has been proven to effectively discriminate neutrons and γ rays, its discrimination performance depends strongly on the selection of the discrimination parameter obtained by the combination of these frequency coefficients. In order to thoroughly understand and apply the DFT-based PSD in organic scintillation detectors, a comparison of three different discrimination parameters, i.e. the amplitude of zero-frequency component, the amplitude difference between the amplitude of zero-frequency component and the amplitude of base-frequency component, and the ratio of the amplitude of base-frequency component to the amplitude of zero-frequency component, is described in this paper. An experimental setup consisting of an Americium–Beryllium (Am–Be) source, a BC501A liquid scintillator detector, and a 5Gsample/s 8-bit oscilloscope was built to assess the performance of the DFT-based PSD with each of these discrimination parameters in terms of the figure-of-merit (based on the separation of the event distributions). The third technique, which uses the ratio of the amplitude of base-frequency component to the amplitude of zero-frequency component as the discrimination parameter, is observed to provide the best discrimination performance in this research. - Highlights: • The spectrum difference between neutron pulse and γ-ray pulse was investigated. • The DFT-based PSD with different parameter definitions was assessed. • The way of using the ratio of magnitude spectrum provides the best performance. • The performance differences were explained from noise suppression features

  8. Multi-electrode circular position-sensitive device (PSD) and its application to angular measurement

    Science.gov (United States)

    Nakajima, Hajime; Shikai, Masahiro; Takashima, Kazuo; Usami, Teruo

    1995-01-01

    Semiconductor position sensitive devices (PSD) enable to measure the position of a light spot using simple construction. A circular PSD, which has a circular photosensitive region, can be used for angular measurement. This paper presents a new type of circular PSD called Multi Electrode Circular PSD (ME-CPSD) and demonstrates its application for angular measurement. This device, constructed on Si substrate, has a photosensitive region, a resistor line and 16 output electrodes. The photosensitive region has the shape of a ring which is formed by a radial arrangement of long and narrow photodiodes. The outer end of the photodiodes are connected to the continuous resistor line. Photoexcited carriers which are generated in the photodiode by the incident light flow to the resistor line and are extracted by the multioutput electrode which divides the resistor into 16 equal parts. To measure the position of the light spot, a pair of electrodes is selected by switches connected to every electrode and the position of the light spot is calculated from the output current of the selected electrodes. Compared to conventional circular PSDs, the reliability of the angular measurement is improved, because the ME-CPSD does not have an undetectable region caused by the unavoidable discontinuity in the structure of conventional circular PSDs. This device can change its measuring range by selecting the pair of electrodes, making it not only capable of measuring any absolute angular position, but allows also a more precise angular measurement by selecting narrower electrode intervals. This device has the capability to realize a high precision noncontact angular measurement system with simple construction.

  9. [A case study of the interrelations among population, health and development. PSD-Mali].

    Konate, M K

    1992-06-01

    The population, health, and development project in Mali (PSD-M) hypothesized that the construction of the Selingue dam would probably improve the income of the populations, cause socio-cultural changes, and degrade the environment. The prevalence of urinary schistosomiasis decreased after construction while the prevalence of intestinal schistosomiasis increased. The prevalence of onchocerciasis fell from 3.6% to 0.2% during 1980-1983. PSD-Mali could not adequately follow up on other parasitic diseases. Information on consumption of fish by the fishermen themselves was unavailable. PSD-Mali did learn, however, that fishing for self-consumption was very much lower than commercial fishing. Fish sales comprised the greatest source of income, so fishing contributed somewhat to improvement of living conditions. Fishing has become a microindustry for the indigenous women, practiced with rudimentary means, with the creation of the artificial lake. The Office for Exploitation of Resources of the Upper Niger lends itself to fishing activities which encourages migration of ethnic fishermen to the Selingue zone. Income-related data were not better available after the dam than before, except for some data related to commercialization of fresh fish. Environmental degradation continues as predicted by PSD-M, which is contradictory to rural practices in the zone. In the past, land was left fallow for several years. 1350 hectares downstream from the dam, 68.7% of which is favorable for growing rice, is not irrigable. Construction of access roads as well as the opening of new tracks allowed deforestation, but the selling of wood for heating, of charcoal, and of bamboo has resulted in a comfortable income. These findings show that there is still need for evaluation of different aspects of life of the population concerned.

  10. Tank Farm WM-182 and WM 183 Heel Slurry Samples PSD Results

    Energy Technology Data Exchange (ETDEWEB)

    Batcheller, Thomas Aquinas

    2000-09-01

    Particle size distribution (PSD) analysis of INTEC Tank Farm WM-182 and WM-183 heel slurry samples were performed using a modified Horiba LA-300 PSD analyzer at the RAL facility. There were two types of testing performed: typical PSD analysis, and setting rate testing. Although the heel slurry samples were obtained from two separate vessels, the particle size distribution results were quite similar. The slurry solids were from approximately a minimum particle size of 0.5 mm to a maximum of 230 mm-with about 90% of the material between 2-to-133 mm, and the cumulative 50% value at approximately 20 mm. This testing also revealed that high frequency sonication with an ultrasonic element may break-up larger particles in the WM-182 and WM-183 tank from heel slurries. This finding represents useful information regarding ultimate tank heel waste processing. Settling rate testing results were also fairly consistent with material from both vessels in that it appears that most of the mass of solids settle to an agglomerated, yet easily redispersed layer at the bottom. A dispersed and suspended material remained in the "clear" layer above the settled layer after about one-half an hour of settling time. This material had a statistical mode of approximately 5 mm and a maximum particle size of 30 mm.

  11. Analysis and Calibration of Sources of Electronic Error in PSD Sensor Response

    Directory of Open Access Journals (Sweden)

    David Rodríguez-Navarro

    2016-04-01

    Full Text Available In order to obtain very precise measurements of the position of agents located at a considerable distance using a sensor system based on position sensitive detectors (PSD, it is necessary to analyze and mitigate the factors that generate substantial errors in the system’s response. These sources of error can be divided into electronic and geometric factors. The former stem from the nature and construction of the PSD as well as the performance, tolerances and electronic response of the system, while the latter are related to the sensor’s optical system. Here, we focus solely on the electrical effects, since the study, analysis and correction of these are a prerequisite for subsequently addressing geometric errors. A simple calibration method is proposed, which considers PSD response, component tolerances, temperature variations, signal frequency used, signal to noise ratio (SNR, suboptimal operational amplifier parameters, and analog to digital converter (ADC quantitation SNRQ, etc. Following an analysis of these effects and calibration of the sensor, it was possible to correct the errors, thus rendering the effects negligible, as reported in the results section.

  12. PSD95 gene specific siRNAs attenuate neuropathic pain through modulating neuron sensibility and postsynaptic CaMKIIα phosphorylation.

    2011-12-01

    To observe the effects of PSD95 gene specific siRNAs on neuropathic pain relief, neuron viability, and postsynaptic calcium/calmodulin-dependent protein kinase IIα (CaMKIIα) phosphorylation in vitro and in vivo. Gene-specific siRNAs of rat PSD95 were synthesized chemically for transfection. Adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups: naïve group (n=6), sham group (n=6), and sciatic nerve chronic constriction injury (CCI) group (n=24). The CCI group was further divided into 4 groups (n=6 in each group), which were pretreated with normal saline, transfection vehicle, negative control siRNAs, and PSD95 gene specific siRNAs respectively. All the subgroups received corresponding agents intrathecally for 3 days, started one day before the CCI of sciatic nerve. Both mechanical allodynia and thermal hyperalgesia were measured on post-operative day 3 and 7. PSD95 gene silenced NG108-15 cells were further stimulated by glutamate, with the cell viability and the expression/phosphorylation of CaMKIIα measured by MTT cell proliferation assay and Western blot, respectively. The siRNAs decreased PSD95 mRNA level significantly both in vivo and in vitro. Neuropathic pain rats pretreated with PSD95 gene specific siRNAs exhibited significant elevation in the mechanical withdrawal threshold and paw withdrawal thermal latency, without affecting the baseline nociception. PSD95 gene silencing enhanced neuronal tolerance against the glutamate excitotoxicity, meanwhile the phosphorylation of CaMKIIα Thr286 was attenuated. Pre-emptive administration of PSD95 gene specific siRNAs may attenuate the central sensitization CaMKIIα-related signaling cascades, leading to the relief of neuropathic pain.

  13. Raw Data-Based Motion Compensation for High-Resolution Sliding Spotlight Synthetic Aperture Radar.

    Science.gov (United States)

    Li, Ning; Niu, Shilin; Guo, Zhengwei; Liu, Yabo; Chen, Jiaqi

    2018-03-12

    For accurate motion compensation (MOCO) in airborne synthetic aperture radar (SAR) imaging, a high-precision inertial navigation system (INS) is required. However, an INS is not always precise enough or is sometimes not even included in airborne SAR systems. In this paper, a new, raw, data-based range-invariant motion compensation approach, which can effectively extract the displacements in the line-of-sight (LOS) direction, is proposed for high-resolution sliding spotlight SAR mode. In this approach, the sub-aperture radial accelerations of the airborne platform are estimated via a well-developed weighted total least square (WTLS) method considering the time-varying beam direction. The effectiveness of the proposed approach is validated by two airborne sliding spotlight C band SAR raw datasets containing different types of terrain, with a high spatial resolution of about 0.15 m in azimuth.

  14. Generalized Chirp Scaling Combined with Baseband Azimuth Scaling Algorithm for Large Bandwidth Sliding Spotlight SAR Imaging.

    2017-05-29

    This paper presents an efficient and precise imaging algorithm for the large bandwidth sliding spotlight synthetic aperture radar (SAR). The existing sub-aperture processing method based on the baseband azimuth scaling (BAS) algorithm cannot cope with the high order phase coupling along the range and azimuth dimensions. This coupling problem causes defocusing along the range and azimuth dimensions. This paper proposes a generalized chirp scaling (GCS)-BAS processing algorithm, which is based on the GCS algorithm. It successfully mitigates the deep focus along the range dimension of a sub-aperture of the large bandwidth sliding spotlight SAR, as well as high order phase coupling along the range and azimuth dimensions. Additionally, the azimuth focusing can be achieved by this azimuth scaling method. Simulation results demonstrate the ability of the GCS-BAS algorithm to process the large bandwidth sliding spotlight SAR data. It is proven that great improvements of the focus depth and imaging accuracy are obtained via the GCS-BAS algorithm.

    Much interest has focussed on glutamate and the N-Methyl-D-Aspartate (NMDA) glutamate receptor in the pathogenesis of schizophrenia. A number of studies have reported abnormal gene transcription of various glutamate receptor subtypes in the hippocampus including the NMDA receptor. However, corresponding protein levels in subregions of the hippocampus have not yet been investigated. We have used immunoautoradiographical techniques to assess the expression of the obligatory NMDA receptor subunit NR1 and an associated post-synaptic density protein PSD-95 in the hippocampal dentate gyrus and orbitofrontal cortex (OFC) in schizophrenia and mood disorder. Optical density measures from film autoradiographs revealed no changes in NR1 or PSD-95 in the OFC or dentate hilus, however a decrease in PSD-95 was found in the dentate molecular layer in both schizophrenia and bipolar disorder relative to major depression. These findings were unrelated to antipsychotic or mood stabilizer drug treatment. The dentate molecular layer contains the dendritic trees of granule cells and is the target of major excitatory afferent inputs from associative cortical, parahippocampal and hippocampal regions. A reduction in PSD-95 at glutamate synapses of the molecular layer may have a deleterious impact on information flow to other hippocampal regions via granule cells and their projecting mossy fibres. A down-regulation of PSD-95 in schizophrenia and bipolar disorder may also relate to disease mechanisms of psychosis.

    Full Text Available A MATLAB/SIMULINK software simulation model (structure and component blocks has been constructed in order to view and analyze the potential of the PSD (Position Sensitive Detector array concept technology before it is further expanded or developed. This simulation allows changing most of its parameters, such as the number of elements in the PSD array, the direction of vision, the viewing/scanning angle, the object rotation, translation, sample/scan/simulation time, etc. In addition, results show for the first time the possibility of scanning an object in 3D when using an a-Si:H thin film 128 PSD array sensor and hardware/software system. Moreover, this sensor technology is able to perform these scans and render 3D objects at high speeds and high resolutions when using a sheet-of-light laser within a triangulation platform. As shown by the simulation, a substantial enhancement in 3D object profile image quality and realism can be achieved by increasing the number of elements of the PSD array sensor as well as by achieving an optimal position response from the sensor since clearly the definition of the 3D object profile depends on the correct and accurate position response of each detector as well as on the size of the PSD array.

    Increased neuroplasticity induced by complex aerobic physical exercise is associated with improved cognitive function in adult mice. Increased cognitive function is assumed to be based on increased synapse formation. One of the regions of the brain that is important in cognitive function is the hippocampus, which plays a role in memory formation. Post synaptic density-95 (PSD-95) is an adhesion protein of the post-synaptic density scaffolding that is essential to synaptic stabilization. As we age, the PSD-95 molecule matures the synapses needed for the formation of the basic circuitry of the nervous system in the brain. However, during the growth period, synapse elimination is higher than its formation. This study aims to determine whether complex aerobic exercise can improve cognitive function and PSD-95 levels in the hippocampus of juvenile mice during their growth stage. The mice performed complex aerobic exercise starting at five weeks of age and continuing for seven weeks with a gradual increase of 8 m/min. At eight weeks it was increased to 10 m/min. The exercise was done for five days of each week. The subjects of the study were tested for cognition one week before being sacrificed (at 12 weeks). The PSD-95 in the hippocampus was measured with ELISA. The results showed that there was a significant difference in cognitive function, where p cognitive ability in adulthood but does not increase the levels of PSD-95 in adults.

  10. Fuzzy norm method for evaluating random vibration of airborne platform from limited PSD data

    Full Text Available For random vibration of airborne platform, the accurate evaluation is a key indicator to ensure normal operation of airborne equipment in flight. However, only limited power spectral density (PSD data can be obtained at the stage of flight test. Thus, those conventional evaluation methods cannot be employed when the distribution characteristics and priori information are unknown. In this paper, the fuzzy norm method (FNM is proposed which combines the advantages of fuzzy theory and norm theory. The proposed method can deeply dig system information from limited data, which probability distribution is not taken into account. Firstly, the FNM is employed to evaluate variable interval and expanded uncertainty from limited PSD data, and the performance of FNM is demonstrated by confidence level, reliability and computing accuracy of expanded uncertainty. In addition, the optimal fuzzy parameters are discussed to meet the requirements of aviation standards and metrological practice. Finally, computer simulation is used to prove the adaptability of FNM. Compared with statistical methods, FNM has superiority for evaluating expanded uncertainty from limited data. The results show that the reliability of calculation and evaluation is superior to 95%.

    Acid-sensing ion channel-1a (ASIC1a) mediates H+-gated current to influence normal brain physiology and impact several models of disease. Although ASIC2 subunits are widely expressed in brain and modulate ASIC1a current, their function remains poorly understood. We identified ASIC2a in dendrites, dendritic spines, and brain synaptosomes. This localization largely relied on ASIC2a binding to PSD-95 and matched that of ASIC1a, which does not co-immunoprecipitate with PSD-95. We found that ASIC2...

  13. Single-Molecule Imaging of PSD-95 mRNA Translation in Dendrites and Its Dysregulation in a Mouse Model of Fragile X Syndrome.

    Ifrim, Marius F; Williams, Kathryn R; Bassell, Gary J

    2015-05-06

    Fragile X syndrome (FXS) is caused by the loss of the fragile X mental retardation protein (FMRP), an RNA binding protein that regulates translation of numerous target mRNAs, some of which are dendritically localized. Our previous biochemical studies using synaptoneurosomes demonstrate a role for FMRP and miR-125a in regulating the translation of PSD-95 mRNA. However, the local translation of PSD-95 mRNA within dendrites and spines, as well as the roles of FMRP or miR-125a, have not been directly studied. Herein, local synthesis of a Venus-PSD-95 fusion protein was directly visualized in dendrites and spines using single-molecule imaging of a diffusion-restricted Venus-PSD-95 reporter under control of the PSD-95 3'UTR. The basal translation rates of Venus-PSD-95 mRNA was increased in cultured hippocampal neurons from Fmr1 KO mice compared with WT neurons, which correlated with a transient elevation of endogenous PSD-95 within dendrites. Following mGluR stimulation with (S)-3,5-dihydroxyphenylglycine, the rate of Venus-PSD-95 mRNA translation increased rapidly in dendrites of WT hippocampal neurons, but not in those of Fmr1 KO neurons or when the binding site of miR125a, previously shown to bind PSD-95 3'UTR, was mutated. This study provides direct support for the hypothesis that local translation within dendrites and spines is dysregulated in FXS. Impairments in the regulated local synthesis of PSD-95, a critical regulator of synaptic structure and function, may affect the spatiotemporal control of PSD-95 levels and affect dendritic spine development and synaptic plasticity in FXS.

    2007-09-01

    Full Text Available This article examines the relations between the European Union (EU and NATO in light of both of the current, deeply unhealthy, state of the transatlantic relationship, and of its ongoing evolution. The first part is devoted to a retrospective outline of the links between European defence and the Atlantic system, which highlights the major constant features of these last sixty years, as well as the rupture points. Then, various issues, from the problem of the division of labour and the definition of the chain of command to coordination on the ground and arms procurement, are evoked as concrete examples where the same fundamental question marks emerge, again and again; all of them revolving around the concept of sovereignty – that of the Europeans vis-à-vis America. It is suggested in the article that current European dependence does not allow but superficial and/or temporary ‘progress’ in EU-NATO relations, just as is the case in the broader Euro-American relationship. As long as Europeans will not assume fully the objective of autonomy (i.e. freedom of decision and action, with all the commitments it would imply, their subjection will continue to generate increasing tensions, since this inherent imbalance is not only detrimental to Europe’s own interests, but it also excludes any reciprocity and prohibits any genuine partnership with the United States.

  15. An Improved Doppler Rate Estimation Approach for Sliding Spotlight SAR Data Based on the Transposition Domain

    Full Text Available In image processing of high-resolution sliding spotlight SAR, it is important to know the Doppler rate with accuracy; however, traditional Doppler rate estimation algorithms are not very helpful because of the azimuth spectrum folding phenomenon. In this study, an algorithm that works on the transposition domain is proposed to solve this problem. Furthermore, the algorithm is also helpful in obtaining excellent focused images by embedding it in the two-step technique. Finally, the proposed algorithm is verified using computer simulations.

    In this paper we describe an algorithm for fast spotlight-mode synthetic aperture radar (SAR) image formation that employs backprojection as the core, but is implemented such that its compute time is comparable to the often-used Polar Format Algorithm (PFA). (Standard backprojection is so much slower than PFA that it is impractical to use in many operational scenarios.) We demonstrate the feasibility of the algorithm on real SAR phase history data sets and show some advantages in the SAR image formed by this technique.

    Shaft calibration is an important technique during installation and maintenance of a rotating machine. It requires unique and high-precision measurement instruments with calculation capability, and relies on experience on heavy, high-speed, or high-temperature machines. A high-precision laser alignment system has been designed using PSD (Position Sensing Detector) to change traditional manual way of shaft calibration and to make the measurement easier and more accurate. The system is comprised of two small measuring units (Laser transmitter and detector) and a hand operated control unit or a PC. Such a laser alignment system has been used in some actual shaft alignment with offset resolution 1.5μm and angular resolution 0.1°.

    2012-02-01

    Middle childhood, from six to 12 years of age, is often known as the 'forgotten years' of development because most research is focused on early childhood development or adolescent growth. However, middle childhood is rich in potential for cognitive, social, emotional and physical advancements. During this period, the brain is actively undergoing synaptic pruning and, as such, is constantly becoming more refined, a process that is heavily dependent on a child's environment. This discovery opens the door to optimizing the experiences a child needs to provide themselves with a strong foundation for adulthood. The present article reviews the neurological changes that occur in middle childhood, their impact on overall development and how to implement this knowledge to augment a child's capabilities.

    Full Text Available Poverty is measured in terms of deficits and unmet basic needs using indicators such as the amount of food intake, income, access to health services, education and housing. This approach assumes that the well is only about the ability to meet the basic needs of food and clothing that are covered, traditionally, with the proceeds of the household head. However, when these revenues are not sufficient for the reproduction of the family, quality of life for women and children were severely affected.This article discusses the role of microfinance as one of the strategies adopted by some countries to reduce poverty in which women live. To achieve this objective, a survey to 82 users of microfinance ProMujer offered through one of its offices in Ixmiquilpan, State of Hidalgo. The results show that women are able to increase the amount of family income and to initiate a process of empowerment, however, and given the flexibility of the labor market, reproduce male domination through economic activities undertaken to use microcredit they are a palliative, but poverty in which they live is not resolved.

    2014-12-01

    Full Text Available This article presents findings from qualitative research which aimed to capture the experience and views of people who were supporting fourteen learners with intellectual disabilities (aged 12-18 to perform with a professional orchestra. Findings have been analysed in two stages. The first analysis, published elsewhere (Rickson 2012, focused on supporters’ experiences of organising and preparing for the performance. The supporters believed that through practising and performing an orchestral work the diverse musicians had the potential to challenge stereotyped portrayals of disability, change attitudes and foster the ongoing inclusion of people with diverse abilities. However, while the learners’ responses during preparatory workshops were described as interesting, meaningful and creative, there seemed to be a general perception that they were vulnerable and in need of protection from potentially unsympathetic audiences. This dichotomy was examined in post-performance interviews with supporters and audience members. Findings, presented here, show that the narrative of vulnerability and ‘overcoming’ persisted. Nevertheless, interviewees remained convinced of the artistic value of the work and believed the learners had the potential to attract wider audiences to their performances. Further opportunities for young people with intellectual disabilities to be involved in community arts projects alongside non-disabled musicians may result.

    Eye movement strategies employed by humans to identify conspecifics are not universal. Westerners predominantly fixate the eyes during face recognition, whereas Easterners more the nose region, yet recognition accuracy is comparable. However, natural fixations do not unequivocally represent information extraction. So the question of whether humans universally use identical facial information to recognize faces remains unresolved. We monitored eye movements during face recognition of Western Caucasian (WC) and East Asian (EA) observers with a novel technique in face recognition that parametrically restricts information outside central vision. We used 'Spotlights' with Gaussian apertures of 2 degrees, 5 degrees or 8 degrees dynamically centered on observers' fixations. Strikingly, in constrained Spotlight conditions (2 degrees and 5 degrees) observers of both cultures actively fixated the same facial information: the eyes and mouth. When information from both eyes and mouth was simultaneously available when fixating the nose (8 degrees), as expected EA observers shifted their fixations towards this region. Social experience and cultural factors shape the strategies used to extract information from faces, but these results suggest that external forces do not modulate information use. Human beings rely on identical facial information to recognize conspecifics, a universal law that might be dictated by the evolutionary constraints of nature and not nurture.

    This paper compares three algorithms for potential use in a real-time, on-board implementation of spotlight-mode SAR image formation. These include: the polar formatting algorithm (PFA), the range migration algorithm (RMA), and the overlapped subapertures algorithm (OSA). We conclude that for any reasonable spotlight-mode imaging scenario, PFA is easily the algorithm of choice because its computational efficiency is significantly higher than that of either RMA or OSA. This comparison specifically includes cases in which wavefront curvature is sufficient to cause image defocus in conventional PFA, because a post-processing refocus step can be performed with PFA to yield excellent image quality for only a minimal increase in computation time. We demonstrate that real-time image formation for many imaging scenarios is achievable using PFA implemented on a single Pentium M processor. OSA is quite slow compared to PFA, especially for the case of moderate to high resolution (9 inches and better). RMA is not competitive with PFA for situations that do not require wavefront curvature correction. For those cases in which PFA requires post-processing to correct for wavefront curvature, RMA comes closer in efficiency to PFA, but is still outperformed by the modified PFA.

    Full Text Available Bonnie L Hay Kraus Department of Veterinary Clinical Sciences, Iowa State University College of Veterinary Medicine, Ames, IA, USA Abstract: Neurokinin-1 (NK-1 receptors are present in both the central nervous system and peripheral tissues. Substance P (SP is the major ligand and is involved in multiple processes including pain transmission, vasodilation, modulation of the inflammatory response, as well as the sensory neuronal transmission involved in stress, anxiety, and emesis. The involvement of NK-1 and SP in the vomiting reflex has led to the development of NK-1 antagonists to prevent and treat vomiting in human and veterinary medicine. Maropitant is a potent, selective neurokinin (NK-1 receptor antagonist that blocks the pharmacologic action of SP in the central nervous system. Maropitant is available in both an injectable and tablet formulation and approved for use in dogs and cats for the treatment and prevention of vomiting from a variety of clinical causes and motion sickness. When administered prior to anesthetic premedication, maropitant prevents or significantly decreases the incidence of opioid-induced vomiting and signs of nausea in dogs and cats. Maropitant has also been shown to improve postoperative return to feeding and food intake in dogs. The minimum alveolar concentration of sevoflurage is decreased in both dogs and cats by maropitant, indicating a potential role as an adjunct analgesic, especially for visceral pain. This article will review the background information and literature, including clinical recommendations with respect to the perioperative use of maropitant in canine and feline veterinary patients.

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

    Male infertility affects >20 million men worldwide and represents a major health concern. Although multifactorial, male infertility has a strong genetic basis which has so far not been extensively studied. Recent studies of consanguineous families and of small cohorts of phenotypically homogeneous patients have however allowed the identification of a number of autosomal recessive causes of teratozoospermia. Homozygous mutations of aurora kinase C (AURKC) were first described to be responsible for most cases of macrozoospermia. Other genes defects have later been identified in spermatogenesis associated 16 (SPATA16) and dpy-19-like 2 (DPY19L2) in patients with globozoospermia and more recently in dynein, axonemal, heavy chain 1 (DNAH1) in a heterogeneous group of patients presenting with flagellar abnormalities previously described as dysplasia of the fibrous sheath or short/stump tail syndromes, which we propose to call multiple morphological abnormalities of the flagella (MMAF). A comprehensive review of the scientific literature available in PubMed/Medline was conducted for studies on human genetics, experimental models and physiopathology related to teratozoospermia in particular globozoospermia, large headed spermatozoa and flagellar abnormalities. The search included all articles with an English abstract available online before September 2014. Molecular studies of numerous unrelated patients with globozoospermia and large-headed spermatozoa confirmed that mutations in DPY19L2 and AURKC are mainly responsible for their respective pathological phenotype. In globozoospermia, the deletion of the totality of the DPY19L2 gene represents ∼ 81% of the pathological alleles but point mutations affecting the protein function have also been described. In macrozoospermia only two recurrent mutations were identified in AURKC, accounting for almost all the pathological alleles, raising the possibility of a putative positive selection of heterozygous individuals.

    The post-synaptic density (PSD) is an electron dense region consisting of ~1000 proteins, found at the postsynaptic membrane of excitatory synapses, which varies in size depending upon synaptic strength. PSD95 is an abundant scaffolding protein in the PSD and assembles a family of supercomplexes comprised of neurotransmitter receptors, ion channels, as well as signalling and structural proteins. We use superresolution STED (STimulated Emission Depletion) nanoscopy to determine the size and shape of PSD95 in the anaesthetised mouse visual cortex. Adult knock-in mice expressing eGFP fused to the endogenous PSD95 protein were imaged at time points from 1 min to 6 h. Superresolved large assemblies of PSD95 show different sub-structures; most large assemblies were ring-like, some horse-shoe or figure-8 shaped, and shapes were continuous or made up of nanoclusters. The sub-structure appeared stable during the shorter (minute) time points, but after 1 h, more than 50% of the large assemblies showed a change in sub-structure. Overall, these data showed a sub-morphology of large PSD95 assemblies which undergo changes within the 6 hours of observation in the anaesthetised mouse.

    The potential performance of a notional active coincidence collar for assaying uranium fuel based on segmented detectors constructed from the new PSD plastic fast organic scintillator with pulse shape discrimination capability was investigated in simulation. Like the International Atomic Energy Agency's present Uranium Neutron Collar for LEU (UNCL), the PSD plastic collar would also function by stimulating fission in the 235U content of the fuel with a moderated 241Am/Li neutron source and detecting instances of induced fission via neutron coincidence counting. In contrast to the moderated detectors of the UNCL, the fast time scale of detection in the scintillator eliminates statistical errors due to accidental coincidences that limit the performance of the UNCL. However, the potential to detect a single neutron multiple times historically has been one of the properties of organic scintillator detectors that has prevented their adoption for international safeguards applications. Consequently, as part of the analysis of simulated data, a method was developed by which true neutron-neutron coincidences can be distinguished from inter-detector scatter that takes advantage of the position and timing resolution of segmented detectors. Then, the performance of the notional simulated coincidence collar was evaluated for assaying a variety of fresh fuels, including some containing burnable poisons and partial defects. In these simulations, particular attention was paid to the analysis of fast mode measurements. In fast mode, a Cd liner is placed inside the collar to shield the fuel from the interrogating source and detector moderators, thereby eliminating the thermal neutron flux that is most sensitive to the presence of burnable poisons that are ubiquitous in modern nuclear fuels. The simulations indicate that the predicted precision of fast mode measurements is similar to what can be achieved by the present UNCL in thermal mode. For example, the

  11. Geolocation with error analysis using imagery from an experimental spotlight SAR

    Science.gov (United States)

    Wonnacott, William Mark

    This dissertation covers the development of a geometry-based sensor model for a specific monostatic spotlight synthetic aperture radar (SAR) system---referred to as the ExSAR (for experimental SAR). This sensor model facilitates single- and multiple-image geopositioning with error analysis. It allows for the use of known ground control points in refining the collection geometry parameters (a process called image resection) and for the subsequent geopositioning of other points using the resected image. Theoretically, the model also allows for the potential recovery of bias-like, persistent errors common across multiple images. The model also includes multi-image correspondence equations to aid in the cross-image identification of conjugate points. The sensor model development begins with a generic, theoretical approach to the modeling of spotlight SAR. A closed-form solution to the range and range-rate condition equations and the corresponding error propagation equation are presented. (The SAR condition equations have traditionally been solved iteratively.) The application of the closed-form solution in the image-to-ground and ground-to-image transformations is documented. The theoretical work also includes a preliminary error sensitivity analysis and a treatment of the spotlight SAR resection process. The ExSAR-specific model is established and assessed with an extensive set of images collected using the experimental radar over arrays of ground control points. Using this set, the imagery metadata elements are assessed, and the optimal element set for geopositioning is determined. The ExSAR imagery is shown to be transformed to the ground plane in only one dimension. The eventual ExSAR sensor model is used with known elevations and single-image geopositioning to show a horizontal accuracy of 8.23 m (rms). With resection using five ground-surveyed control points per image, the horizontal accuracy of reserved check points is 0.45 m (rms). Resections using the same

    Full Text Available Abstract Background The prevalence of overweight and obesity in Europe is high. It is a major cause of the overall rates of many of the main chronic (or non communicable diseases in this region and is characterized by an unequal socio-economic distribution within the population. Obesity is largely determined by modifiable lifestyle behaviours such as low physical activity levels, sedentary behaviour and consumption of energy dense diets. It is increasingly being recognised that effective responses must go beyond interventions that only focus on a specific individual, social or environmental level and instead embrace system-based multi-level intervention approaches that address both the individual and environment. The EU-funded project “sustainable prevention of obesity through integrated strategies” (SPOTLIGHT aims to increase and combine knowledge on the wide range of determinants of obesity in a systematic way, and to identify multi-level intervention approaches that are strong in terms of Reach, Efficacy, Adoption, Implementation and Maintenance (RE-AIM. Methods/Design SPOTLIGHT comprises a series of systematic reviews on: individual-level predictors of success in behaviour change obesity interventions; social and physical environmental determinants of obesity; and on the RE-AIM of multi-level interventions. An interactive web-atlas of currently running multi-level interventions will be developed, and enhancing and impeding factors for implementation will be described. At the neighbourhood level, these elements will inform the development of methods to assess obesogenicity of diverse environments, using remote imaging techniques linked to geographic information systems. The validity of these methods will be evaluated using data from surveys of health and lifestyles of adults residing in the neighbourhoods surveyed. At both the micro- and macro-levels (national and international the different physical, economical, political and socio

    Cortical spreading depression is associated with activation of NMDA receptors, which interact with the postsynaptic density protein 95 (PSD-95) that binds to nitric oxide synthase (nNOS). Here, we tested whether inhibition of the nNOS/PSD-95/NMDA receptor complex formation by anti-ischemic compound......, UCCB01-144 (Tat-N-dimer) ameliorates the persistent effects of cortical spreading depression on cortical function. Using in vivo two-photon microscopy in somatosensory cortex in mice, we show that fluorescently labelled Tat-N-dimer readily crosses blood-brain barrier and accumulates in nerve cells...... during the first hour after i.v. injection. The Tat-N-dimer suppressed stimulation-evoked synaptic activity by 2-20%, while cortical blood flow and cerebral oxygen metabolic (CMRO2) responses were preserved. During cortical spreading depression, the Tat-N-dimer reduced the average amplitude...

    In Zimbabwe, a reproductive health survey conducted in 1984 revealed the highest rate of contraceptive use in sub-Saharan Africa -- 38% of currently married women were using some form of family planning and 27% a modern contraceptive method. The majority of Zimbabwe's population, a country formerly known a Rhodesia, is African, but there also are about 100,000 whites, 20,000 persons of mixed race, and 10,000 Asians. Robert Mugabe formed the 1st government of Zimbabwe as a result of elections held in February 1980. Since independence, rifts have developed between the black nationalist leaders -- Robert Mugabe and Joshua Nkomo -- and continues. Some guerrilla activity has occurred in rural areas and antigovernment dissidence creating security and economic problems. Zimbabwe has a broad range of natural resources -- large mineral deposits including coal, asbestos, copper, nickel, gold, and iron ore. In addition to a well-developed electrical power network, there is a good infrastructure of paved roads and a vital railroad link with neighboring South Africa. Due to the trade sanctions imposed between 1965 and independence, the country has had to look inward for production. The manufacturing sector is well developed as is agriculture. The government identifies the country's most urgent problems as the resettlement of displaced persons and reconstruction of roads, health establishments, and schools destroyed during guerrilla activity.

  16. Spotlight: Afghanistan.

    Science.gov (United States)

    Felt, J C

    1988-05-01

    Afghanistan is a landlocked country approximately the size of Texas with an estimated population of 14.5 million. The fertility level (6.7 children per women) is estimated to be very high, as is the mortality rate (183 infant deaths/1,000 live births). Demographic data sources are scarce, and current estimates are based on a 1972-1974 series of surveys and a 1979 census which enumerated only 55-60% of the population. The government of Afghanistan, a Marxist state, has asked for international aid to improve data collection and analysis. Compounding the problems of accurate data collection is the state of civil war that has existed in Afghanistan since the Marxist coup in in 1978 and Soviet occupation in 1979. The war impelled the emigration of 5 million refugees, who live in camps in neighboring Pakistan and Iran. Although the population decline that resulted from this emigration is significant, the repatriation of the refugees will play a role in determining the population dynamics for the next decade, as will the withdrawal of Soviet troops -- expected in 1990. Because of Afghanistan's central-Asia location, there is a unique ethnic and linguistic mixture of tribes. The largest group is the Pushtus, who make up 40% of the population. Afghan Persian and Pushtu are the dominant languages, and 98% of all Afghans are Moslem. The economy is largely agricultural and half the cultivated land must be irrigated. 85% of the population live in rural areas and another 2.5 million are nomads. The low status of women and female children, low levels of health care, and high fertility contribute to the lower life expectancy of females over males. Although the government supports contraceptive services, such services are inadequate, and sterilization is illegal. The withdrawal of Soviet troops and the possible end to civil war between the Kabul government and the rebel factions, and the effects of repatriation of refugees will determine the direction of Afghanistan's future development.

  17. Pakistan. Spotlight.

    Science.gov (United States)

    Greene, M

    1985-01-01

    Focus in this discussion of Pakistan is on demographic factors, the issue of ethnic versus national solidarity, and economic and social development. The population was estimated at 99.2 million in 1985. The birthrate was 43/1000 in 1984 and the deaths were 15/1000. The infant mortality rate is 105 infant deaths/1000 live births, and life expectancy at birth is 51 years. In 1983 the gross national product per capita was US$390. The population of Pakistan is concentrated around Karachi on the Arabian Sea and in the crescent formed by Lahore, Rawalpindi, and Peshawar. Pakistan was a British colony, part of the Indian subcontinent until partition in 1947, when Britain gave Pakistan and India their freedom. Pakistan is not a theocracy, but the military government turns to traditional Islam for affirmation of its authority. Its martial law regime, established in 1977, is headed by President Ziaul Haq. The issue of ethnic versus national solidarity has been a problem since independence. Bengali-speaking East Pakistanis felt they did not have equal power in their country whose official language was Urdu and whose capital was in West Pakistan. East and West Pakistan ended up in armed conflict with the formation of Bangladesh in 1971 as the result. Regional and ethnic conflict is exacerbated by the low rate of literacy and the low status of certain ethnic groups in Pakistan. In addition, Pakistan suffers problems typical of many developing nations: a low per capita income, a large and growing population, and a highly stratified traditional society. In 1981 doctors, engineers, and craftsmen were in short supply, but there was a surplus of 300,000 agricultural workers. Agriculture makes up 30% of the GNP and employs 55% of the work force. In Pakistan's 6th Five Year Plan, initiated in July 1983, the government acknowledged for the 1st time the extremely poor conditions for women as indicated by literacy, health, and fertility. The total fertility rate is 6.4 average births/woman. Although the government is ostensibly trying to help women, funding for women's programs during the Five Year Plan was cut. Economic growth has been good in recent years, but agricultural growth is a result of increased acreage rather than yield per acre.

  18. Iran: spotlight.

    Science.gov (United States)

    Roudi, N

    1987-09-01

    Given its location between Asia and Asia Minor, Iran has been a country of strategic political importance throughout history. More than 98% of Iran's population is Moslem. During the early 20th century, as Iran gradually gained independence from the USSR and Turkey, a modernization process was begun. However, this modernization process was forced to yield to Islamic traditionalism after the 1979 Islamic Revolution. Women have been most affected by this change. The implementation of Islamic traditions has meant low job opportunity or motivation for continuing education among women. Although fertility remains high, the present government is satisfied with the current rate of population growth. Family planning is allowed if implemented within the framework of Islamic law, but abortion is illegal. Mortality fell substantially after World War II, but has not continued to decline. At present, both males and females have the same life expectancy at birth. Iran's population is growing at a rate of 4%/year, and can be expected to double in another 21 years. It has been projected that Iran, currently the 21st largest country in the world with a population of 50 million, will become the 15th largest with a population of 97 million by the year 2025. Tehran, the 20th largest city in 1985, is projected to be the 9th largest by the year 2000, with a population of 13.6 million.

  19. Spotlight: Malaysia.

    Science.gov (United States)

    Patriquin, W

    1988-03-01

    Focus is on Malaysia -- its population and land area, its total fertility rate and mortality rate, economic development, contraceptive usage, and population policy. In 1987 Malaysia's population was estimated to be 16.1 million with births 31/1000 population and deaths 7/1000 population. The rate of natural increase is 2.4%, the total fertility rate 3.9 children/woman, and the infant mortality rate 30/1000 live births. Ethnically, Malaysia is made up of several distinct groups. Indigenous Malays are the most numerous -- about 50% of the population. Their unique characteristics include that they are Moslem, rural, and usually of lower economic status. Chinese make up the 2nd largest group of Malaysians, nearly 1/3 of the population. This group is active in trade, business, and finance and possesses considerable economic power. About 10% of the population is of Indian descent. Malaysia has experienced much economic growth. Traditional exports grew in volume and value during the 1970; the petroleum sector expanded so rapidly it accounts for 1/4 of all exports. One reason for Malaysia's rapid economic growth is the government's promotion of industrialization and foreign investment. According to the 1982 contraceptive prevalence survey, 42% of currently married women 15-44 years were using contraception. The government considers the current rate of national increase to be satisfactory, but in 1984 it adopted a population policy to more than quadruple its population in 2100 to 70 million. It intends to accomplish this by instituting pronatalist incentives to help the fall in the national growth rate. The government's rationale for more population growth is that a larger domestic population could better support industrial growth that otherwise might be stymied by "protectionist policies practiced by developed countries." Incentives to encourage fertility include income-tax deductions and maternity benefits for women who have up to 5 children.

  20. Spotlight: Barbados.

    Science.gov (United States)

    1984-03-01

    Barbados was among the first to advocate a national system of family planning. In 1954 a joint committee report of birth legislation recommended the institution of a family planning system under the aegis of the government. The country's 1980 total fertility rate of 1.9 live births/woman attests to the success of the program. The rate is among the lowest of any developing nation. The population of Barbados was 122,298 at the 1st post emancipation census in 1844. In 1946 the population totaled 193,680. To a considerable extent, this very low rate of growth (0.46%) was due to substantial emigration, first to Trinidad and Guyana and later to countries outside the region such as the UK and more recently the US and Canada. Net emigration was so great between 1881 and 1921 that it exceeded natural increase by 54%. Consequently, the population declined from 182,867 to 156,724. By 1960, the population had reached 232,820, some 40,000 more than in 1946. Since then growth has been slow. Such a remarkably low rate of growth since World War 2 has been accomplished through continued high levels of emigration combined with declining fertility and mortality. The total fertility rate dropped from 4.7 in 1960 to 3.0 in 1970 to 1.9 in 1980. Life expectancy rose from about 50 in 1946 to 70 in 1980. Levels of net emigration have always been high and remain so. About 18,000 more persons left the country than entered it during the 1970s, a rate of 7.5/1000 population. While high, it is lower than in the 1960s. The mainstays of the economy are sugar and tourism. Since independence in 1966, sugar production has fallen steadily in response to depressed world sugar prices as well as increasing production costs. In recent years the government has sought to reduce dependence on the sugar industry. Tourism, adversely affected by the world recession, shows some signs of recovery. The discovery of some petroleum and natural gas may help. Barbados has one of the most developed infrastructures in the Caribbean and the government hopes to deal with current problems through diversification of the economy. As Barbados is the most densely populated country in the hemisphere, specialists agree that even a future population of 300,000 may be beyond the island's capacity. Because of high 1950s fertility, the labor force is expected to increase by 25% by the year 2000, a serious issue considering that current unemployment is already 14.7% After 2015, Barbados will be faced with an "elderly problem." Given its current demographic behavior, Barbados is in a better position to address and solve these problems than most developing countries.

  1. Spotlight: Azerbaijan.

    Science.gov (United States)

    1999-02-01

    As of mid-1998, Azerbaijan had a population of 7.7 million people residing in a land area of 33,436 square miles. There were 17 births and 6 deaths per 1000 population, as well as 19 infant deaths for every 1000 live births, and a population growing in size at 1.1% annually. The average woman had 2.1 births during her reproductive lifetime and life expectancy was 67 years for men and 74 years for women. Azerbaijan is an oil-producing country, although the agricultural sector is responsible for 25% of gross domestic product and employs 31% of the work force. Despite its oil wealth and strong agricultural and mining sectors, Azerbaijan is struggling to improve its environmental conditions and support a large refugee population. The country's air, water, and soil are severely polluted. Air pollution stems from petrochemical plants, refineries, exhaust fumes, and the burning of untreated garbage; water pollution is the result of oil spills, leaky pipelines and tanks, runoff of fertilizers and pesticides, and improperly treated sewage; and land pollution is due to inadequate waste management. The high incidence of waterborne diseases, including cholera, in Azerbaijan is caused by the inadequate treatment of drinking water and sewage intrusion into leaky distribution pipes. Although over 90% of infants under age 1 year are immunized against diphtheria, whooping cough, tetanus, polio, and measles, babies in Azerbaijan are 3 times as likely to die before reaching age 1 year than are babies in the US. Azerbaijani children are 5 times more likely to die by age 5 than are US children. Living conditions are especially difficult for the 12% of the overall population which are refugees.

  2. Spotlight: Vietnam.

    Science.gov (United States)

    1984-02-01

    Vietnam, with 57 million people, ranks as the world's 13th most populous country with much of the population concentrated in the rice producing areas of the coastal lowlands and the Mekong and Red River valleys. Since reunification, economic recovery has been difficult. Following the failure of the 1976-80 5-Year Plan, the 1981-85 Plan calls for increased food production and the attainment of self sufficiency. Part of this policy is the reduction of the population growth rate. Vietnam's labor force is about 70% agricultural, with women making up about 2/3 of the farm work force. Most heavy industry is in the North and, although badly damaged in the war, has regained much of its capacity. Coal continues to be Vietnam's leading export. The country's extensive forests also provide great potential for the lumber industry and Vietnam has recently begun offshore oil production. Yet, recovery has been elusive. Foreign aid now comes from the Soviet Union, China, Eastern Europe, and France. In recent years the foreign trade balance has improved, but there have been some setbacks in food production. Efforts to raise food production by encouraging private development of unused land have not been very successful, partly because of the continuing shortage of fertilizers, farm machinery, and insecticides. It is also likely that economic progress has been retarded by large military expenditures necessitated by the wars with Cambodia and China. 1 of the government's major efforts has been a large scale population redistribution from urban areas to the less densely inhabited provinces. New Economic Zones have been established in these areas in the hope that new residents will become self sufficient as soon as possible. As part of its national policy, the government has set a goal to reduce the rate of population growth to 1.5% by 1981 through the National Family Planning Program. Officially reported crude birthrates reflect a decline in fertility from about 40/1000 population in 1976 to about 29 in 1980.

  3. Post-translational modifications modulate ligand recognition by the third PDZ domain of the MAGUK protein PSD-95.

    Directory of Open Access Journals (Sweden)

    Javier Murciano-Calles

    Full Text Available The relative promiscuity of hub proteins such as postsynaptic density protein-95 (PSD-95 can be achieved by alternative splicing, allosteric regulation, and post-translational modifications, the latter of which is the most efficient method of accelerating cellular responses to environmental changes in vivo. Here, a mutational approach was used to determine the impact of phosphorylation and succinimidation post-translational modifications on the binding affinity of the postsynaptic density protein-95/discs large/zonula occludens-1 (PDZ3 domain of PSD-95. Molecular dynamics simulations revealed that the binding affinity of this domain is influenced by an interplay between salt-bridges linking the α3 helix, the β2-β3 loop and the positively charged Lys residues in its high-affinity hexapeptide ligand KKETAV. The α3 helix is an extra structural element that is not present in other PDZ domains, which links PDZ3 with the following SH3 domain in the PSD-95 protein. This regulatory mechanism was confirmed experimentally via thermodynamic and NMR chemical shift perturbation analyses, discarding intra-domain long-range effects. Taken together, the results presented here reveal the molecular basis of the regulatory role of the α3 extra-element and the effects of post-translational modifications of PDZ3 on its binding affinity, both energetically and dynamically.

    Mountain glaciers around the world are retreating rapidly, contributing about 20% to present-day sea level rise. Numerous studies have shown that mountain glaciers are sensitive to global environmental change. Temperate-latitude glaciers and snowpack provide water for over 1 billion people. Glaciers are a resource for irrigation and hydroelectric power, but also pose flood and avalanche hazards. Accurate mass balance assessments have been made for only 280 glaciers, yet there are over 130,000 in the World Glacier Inventory. The rate of glacier retreat or advance can be highly variable, is poorly sampled, and inadequately understood. Liquid water from ice front lakes, rain, melt, or sea water and debris from rocks, dust, or pollution interact with glacier ice often leading to an amplification of warming and further melting. Many mountain glaciers undergo rapid and episodic events that greatly change their mass balance or extent but are sparsely documented. Events include calving, outburst floods, opening of crevasses, or iceberg motion. Spaceborne high-resolution spotlight optical imaging provides a means of clarifying the relationship between the health of mountain glaciers and global environmental change. Digital elevation models (DEMs) can be constructed from a series of images from a range of perspectives collected by staring at a target during a satellite overpass. It is possible to collect imagery for 1800 targets per month in the ×56° latitude range, construct high-resolution DEMs, and monitor changes in high detail over time with a high-resolution optical telescope mounted on the International Space Station (ISS). Snow and ice type, age, and maturity can be inferred from different color bands as well as distribution of liquid water. Texture, roughness, albedo, and debris distribution can be estimated by measuring bidirectional reflectance distribution functions (BRDF) and reflectance intensity as a function of viewing angle.

    Keeping up with the latest developments is not easy, but neither is reading articles on research. There are too many medical journals that contain information that is irrelevant to clinical practice. From this mass of articles you have to decide which are important for your own clinical practice and which are not. Most articles naturally fall into the latter category as spectacular findings with important consequences for medical practice do not occur every week. The most important thing in a research article is the research question. If you begin with this, then you can put aside much scientific literature. The methodology section is essential; reading this can save you a lot of time. In this article we take you step-by-step through the process of reading research articles. The articles in our Methodology series can be used as background information. These articles have been combined in a tablet app, which is available via www.ntvg.nl/methodologie.

  17. Bildung, Erziehung [education] and care in German early childhood settings – spotlights on current discourses

    Directory of Open Access Journals (Sweden)

    Frindte Annegret

    2017-08-01

    Full Text Available In German there is a long tradition of institutionalized daycare center-based early education. These institutions are concerned with Bildung, Erziehung und Betreuung - the education and care of children up to six years of age. Education and childrearing as well as care are all important but separate processes in German early childhood settings. Looking back, this theoretical division has a very long tradition. However, the energized public, political and professional discussions about the PISA results at the beginning of the 21st century led to Bildung and ECEC settings becoming increasingly important. Taking into account this complex and difficult historical development it is interesting to have a critical look at the dominant programmatic frames that characterize the German ECEC system nowadays: Bildung and quality of early education. The former double motif of education (Bildung und Erziehung on the one hand and care (Betreuung on the other hand remains an important aspect of German ECEC practices. Nevertheless, in the political arena and professional discourses Erziehung and Betreuung have been pushed into the background, to remain in symbolic form. Bildung and quality of early education seem to be in the spotlight. We will show how those programmatic frames have taken shape and are manifested in early childhood programs and projects.

  18. Comparison of polar formatting and back-projection algorithms for spotlight-mode SAR image formation

    Science.gov (United States)

    Jakowatz, Charles V., Jr.; Doren, Neall

    2006-05-01

    The convolution/back-projection (CBP) algorithm has recently once again been touted as the "gold standard" for spotlight-mode SAR image formation, as it is proclaimed to achieve better image quality than the well-known and often employed polar formatting algorithm (PFA). In addition, it has been suggested that PFA is less flexible than CBP in that PFA can only compute the SAR image on one grid and PFA cannot add or subtract pulses from the imaging process. The argument for CBP acknowledges the computational burden of CBP compared to PFA, but asserts that the increased image accuracy and flexibility of the formation process is warranted, at least in some imaging scenarios. Because CBP can now be sped up by the proper algorithm design, it becomes, according to this line of analysis, the clear algorithm of choice for SAR image formation. In this paper we reject the above conclusion by showing that PFA and CBP achieve the same image quality, and that PFA has complete flexibility, including choice of imaging plane, size of illuminated beam area to be imaged, resolution of the image, and others. We demonstrate these claims via formation of both simulated and real SAR imagery using both algorithms.

  19. Investigation of the Deposition and Densification Parameters on the Mechanical Properties of Pressurized Spray Deposited (PSD) 3-D Printed Ceramic Components

    Energy Technology Data Exchange (ETDEWEB)

    Menchhofer, Paul A [ORNL; Becker, Benjamin [Hot End Works

    2016-07-28

    Oak Ridge National Laboratory (ORNL) and HotEnd Works teamed to investigate the use of pressurized spray deposition (PSD) technology for the production of ceramic parts via additive manufacturing. Scanning electron microscopy of sintered parts provided by HotEnd Works revealed voids large enough to compromise the mechanical properties of PSD manufactured parts. Scanning electron microscopy and particle size analysis of the alumina oxide powder feedstocks indicated that the powders contained some large particles and some agglomerations in the powder. Further classification of the powder feedstocks and removal of the agglomerates by sonication in the liquid used for the PSD process are recommended. Analysis of sintered parts indicated that the sonic modulus for the alumina part is consistent with other known values for alumina. The density for this part was determined by standard Archimedes immersion density methods and was found to be > 99.7 % of the theoretical density for pure alumina.

  20. PSD95 suppresses dendritic arbor development in mature hippocampal neurons by occluding the clustering of NR2B-NMDA receptors.

    Directory of Open Access Journals (Sweden)

    Fernando J Bustos

    Full Text Available Considerable evidence indicates that the NMDA receptor (NMDAR subunits NR2A and NR2B are critical mediators of synaptic plasticity and dendritogenesis; however, how they differentially regulate these processes is unclear. Here we investigate the roles of the NR2A and NR2B subunits, and of their scaffolding proteins PSD-95 and SAP102, in remodeling the dendritic architecture of developing hippocampal neurons (2-25 DIV. Analysis of the dendritic architecture and the temporal and spatial expression patterns of the NMDARs and anchoring proteins in immature cultures revealed a strong positive correlation between synaptic expression of the NR2B subunit and dendritogenesis. With maturation, the pruning of dendritic branches was paralleled by a strong reduction in overall and synaptic expression of NR2B, and a significant elevation in synaptic expression of NR2A and PSD95. Using constructs that alter the synaptic composition, we found that either over-expression of NR2B or knock-down of PSD95 by shRNA-PSD95 augmented dendritogenesis in immature neurons. Reactivation of dendritogenesis could also be achieved in mature cultured neurons, but required both manipulations simultaneously, and was accompanied by increased dendritic clustering of NR2B. Our results indicate that the developmental increase in synaptic expression of PSD95 obstructs the synaptic clustering of NR2B-NMDARs, and thereby restricts reactivation of dendritic branching. Experiments with shRNA-PSD95 and chimeric NR2A/NR2B constructs further revealed that C-terminus of the NR2B subunit (tail was sufficient to induce robust dendritic branching in mature hippocampal neurons, and suggest that the NR2B tail is important in recruiting calcium-dependent signaling proteins and scaffolding proteins necessary for dendritogenesis.

  5. Putting the learner in the spotlight – Future directions for English teachers

    Directory of Open Access Journals (Sweden)

    Anne P A Swan

    2013-10-01

    Full Text Available This paper asserts that English teachers’ understanding of their professionalism enables them to ‘put the learner in the spotlight’ through their highly-developed awareness of local contexts of English use. Changing attitudes to English language teacher identity include a revaluation of the’ native-non-native speaker’ dichotomy which is fast becoming irrelevant as teachers assert new identities based on factors such as professional beliefs about their teaching, understanding their students’ needs and understanding the role of English in their contexts. In a globalising world, these aspects no longer require ‘so-called’ native speaker skills, such as pronunciation and knowledge of ‘English’ culture. In fact, dwelling at length on the issues surrounding native and non-native speaker teacher identity tends to cloud understanding of what qualities English teachers need. Interviews with multilingual teachers of English, working in a variety of countries, have revealed an understanding of the diminishing importance of the ‘native speaker’ and the concomitant growth in the confidence of the multilingual teacher. This confidence has been acquired through depth of linguistic knowledge, through observance of other cultures, and through resistance to the encroachment of English by finding a place for the language which satisfies the needs of multilingual users without requiring subservience. In discovering these strengths of multilingual teachers, I show how stepping outside the boundaries of one’s own limited environment allows English language teachers, wherever they come from, to develop a truly enlightened international professionalism which puts learners firmly in the spotlight.

    Excited states in {sup 20}O were populated in the reaction {sup 10}Be({sup 14}C,{alpha}) at Florida State University (FSU). Charged particles were detected with a particle telescope consisting of 4 annularly segmented Si surface barrier detectors and {gamma} radiation was detected with the FSU {gamma} detector array. Five new states were observed below 6 MeV from the {alpha}-{gamma} and {alpha}-{gamma}-{gamma} coincidence data. Shell model calculations suggest that most of the newly observed states are core-excited 1p-1h excitations across the N=Z=8 shell gap. Comparisons between experimental data and calculations for the neutron-rich O and F isotopes imply a steady reduction of the p-sd shell gap as neutrons are added.

  10. Single-Side Two-Location Spotlight Imaging for Building Based on MIMO Through-Wall-Radar

    Directory of Open Access Journals (Sweden)

    Yong Jia

    2016-09-01

    Full Text Available Through-wall-radar imaging is of interest for mapping the wall layout of buildings and for the detection of stationary targets within buildings. In this paper, we present an easy single-side two-location spotlight imaging method for both wall layout mapping and stationary target detection by utilizing multiple-input multiple-output (MIMO through-wall-radar. Rather than imaging for building walls directly, the images of all building corners are generated to speculate wall layout indirectly by successively deploying the MIMO through-wall-radar at two appropriate locations on only one side of the building and then carrying out spotlight imaging with two different squint-views. In addition to the ease of implementation, the single-side two-location squint-view detection also has two other advantages for stationary target imaging. The first one is the fewer multi-path ghosts, and the second one is the smaller region of side-lobe interferences from the corner images in comparison to the wall images. Based on Computer Simulation Technology (CST electromagnetic simulation software, we provide multiple sets of validation results where multiple binary panorama images with clear images of all corners and stationary targets are obtained by combining two single-location images with the use of incoherent additive fusion and two-dimensional cell-averaging constant-false-alarm-rate (2D CA-CFAR detection.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

  10. Dense ceramic articles

    International Nuclear Information System (INIS)

    Cockbain, A.G.

    1976-01-01

    A method is described for the manufacture of articles of substantially pure dense ceramic materials, for use in severe environments. Si N is very suitable for use in such environments, but suffers from the disadvantage that it is not amenable to sintering. Some disadvantages of the methods normally used for making articles of Si N are mentioned. The method described comprises mixing a powder of the substantially pure ceramic material with an additive that promotes densification, and which is capable of nuclear transmutation into a gas when exposed to radiation, and hot pressing the mixture to form a billet. The billet is then irradiated to convert the additive into a gas which is held captive in the billet, and it is then subjected to a hot forging operation, during which the captive gas escapes and an article of substantially pure dense ceramic material is forged. The method is intended primarily for use for Si N, but may be applied to other ceramic materials. The additive may be Li or Be or their compounds, to the extent of at least 5 ppm and not more than 5% by weight. Irradiation is effected by proton or neutron bombardment. (UK)

  11. Space-variant post-filtering for wavefront curvature correction in polar-formatted spotlight-mode SAR imagery

    Science.gov (United States)

    Doren, Neall Evan

    Wavefront curvature defocus effects occur in spotlight-mode SAR imagery when reconstructed via the well-known polar-formatting algorithm (PFA) under certain imaging scenarios. These include imaging at close range, using a very low radar center frequency, utilizing high resolution, and/or imaging very large scenes. Wavefront curvature effects arise from the unrealistic assumption of strictly planar wavefronts illuminating the imaged scene. This dissertation presents a method for the correction of wavefront curvature defocus effects under these scenarios, concentrating on the generalized, squint-mode imaging scenario and its computational aspects. This correction is accomplished through an efficient one-dimensional, image domain filter applied as a post-processing step to PFA. This post-filter, referred to as SVPF, is precalculated from a theoretical derivation of the wavefront curvature effect and varies as a function of scene location. Prior to SVPF, severe restrictions were placed on the imaged scene size in order to avoid defocus effects under these scenarios when using PFA. The SVPF algorithm eliminates the need for scene size restrictions when wavefront curvature effects are present, correcting for wavefront curvature in broadside as well as squinted collection modes while imposing little additional computational penalty for squinted images. This dissertation covers the theoretical development, implementation and analysis of the generalized, squint-mode SVPF algorithm (of which broadside-mode is a special case) and provides examples of its capabilities and limitations as well as offering guidelines for maximizing its computational efficiency. Tradeoffs between the PFA/SVPF combination and other spotlight-mode SAR image formation techniques are discussed with regard to computational burden, image quality, and imaging geometry constraints. It is demonstrated that other methods fail to exhibit a clear computational advantage over polar-formatting in conjunction

    2018-04-01

    An accurate and stable identification technique is developed to retrieve the optical constants and particle size distributions (PSDs) of particle system simultaneously from the multi-wavelength scattering-transmittance signals by using the improved quantum particle swarm optimization algorithm. The Mie theory are selected to calculate the directional laser intensity scattered by particles and the spectral collimated transmittance. The sensitivity and objective function distribution analysis were conducted to evaluate the mathematical properties (i.e. ill-posedness and multimodality) of the inverse problems under three different optical signals combinations (i.e. the single-wavelength multi-angle light scattering signal, the single-wavelength multi-angle light scattering and spectral transmittance signal, and the multi-angle light scattering and spectral transmittance signal). It was found the best global convergence performance can be obtained by using the multi-wavelength scattering-transmittance signals. Meanwhile, the present technique have been tested under different Gaussian measurement noise to prove its feasibility in a large solution space. All the results show that the inverse technique by using multi-wavelength scattering-transmittance signals is effective and suitable for retrieving the optical complex refractive indices and PSD of particle system simultaneously.

    Excessive N-Methyl-d-aspartate receptor (NMDAR)-dependent production of nitric oxide (NO) is involved in the development and maintenance of chronic pain states, and is mediated by postsynaptic density protein-95 (PSD-95). By binding to both the NMDAR and neuronal NO synthase (nNOS), PSD-95 mediates...... a specific coupling between NMDAR activation and NO production. NMDAR antagonism shows anti-nociceptive action in humans and animal models of chronic pain but is associated with severe disturbances of cognitive and motor functions. An alternative approach to modulate the NMDAR-related activity is to perturb......'s adjuvant (CFA) model of inflammatory pain. To examine side-effect profiles we also compared the effects of UCCB01-125 and MK-801 in tests of attention, long-term memory, and motor performance.

    This study analyzed newspaper coverage of the 2012 London Paralympic Games by 8 Malaysian newspapers. Articles and photographs from 4 English-language and 4 Malay-language newspapers were examined from August 28 (1 day before the Games) to September 10, 2012 (1 day after the Games closing). Tables, graphs, letters, fact boxes, and lists of events were excluded from analysis. A total of 132 articles and 131 photographs were analyzed. Content analysis of the newspaper articles revealed that most (62.8%) of the articles contained positive reference to the athletes with a disability. There were equal numbers (39.1%) of action and static shots of athletes. More articles and photographs of Malaysian (58%) than non-Malaysian (42%) athletes with a disability were identified. Only 14.9% of the articles and photographs were related to female athletes with a disability.

    The inherited metabolic disease phenylketonuria (PKU) is characterized by increased concentrations of phenylalanine in the blood and brain, and as a consequence neurotransmitter metabolism, white matter, and synapse functioning are affected. A specific nutrient combination (SNC) has been shown to improve synapse formation, morphology and function. This could become an interesting new nutritional approach for PKU. To assess whether treatment with SNC can affect synapses, we treated PKU mice with SNC or an isocaloric control diet and wild-type (WT) mice with an isocaloric control for 12 weeks, starting at postnatal day 31. Immunostaining for post-synaptic density protein 95 (PSD-95), a post-synaptic density marker, was carried out in the hippocampus, striatum and prefrontal cortex. Compared to WT mice on normal chow without SNC, PKU mice on the isocaloric control showed a significant reduction in PSD-95 expression in the hippocampus, specifically in the granular cell layer of the dentate gyrus, with a similar trend seen in the cornus ammonis 1 (CA1) and cornus ammonis 3 (CA3) pyramidal cell layer. No differences were found in the striatum or prefrontal cortex. PKU mice on a diet supplemented with SNC showed improved expression of PSD-95 in the hippocampus. This study gives the first indication that SNC supplementation has a positive effect on hippocampal synaptic deficits in PKU mice.

    Full Text Available When related to a single and good contrast object or a laser spot, position sensing, or sensitive, detectors (PSDs have a series of advantages over the classical camera sensors, including a good positioning accuracy for a fast response time and very simple signal conditioning circuits. To test the performance of this kind of sensor for microrobotics, we have made a comparative analysis between a precise but slow video camera and a custom-made fast PSD system applied to the tracking of a diffuse-reflectivity object transported by a pneumatic microconveyor called Smart-Surface. Until now, the fast system dynamics prevented the full control of the smart surface by visual servoing, unless using a very expensive high frame rate camera. We have built and tested a custom and low cost PSD-based embedded circuit, optically connected with a camera to a single objective by means of a beam splitter. A stroboscopic light source enhanced the resolution. The obtained results showed a good linearity and a fast (over 500 frames per second response time which will enable future closed-loop control by using PSD.

    Old Dominion is a not-for-profit generation and transmission cooperative owned by and serving twelve member electric distribution cooperatives in Virginia, Maryland and Delaware. These member cooperatives purchase from Old Dominion all the electric power they supply to over 345,000 member consumers. In 1988, Old Dominion evaluated its long term power needs, and the fact that 300 Megawatts (MW) of base power would have to be replaced by the end of 1994. A power supply alternative study was conducted, and concluded that the interests of the cooperative members would best be served through the construction of a conventional pulverized coal-fired generating units. After comprehensive evaluation and negotiations, Old Dominion signed a contract in April, 1989 with the Consortium of Combustion Engineering, H. B. Zachry, Black ampersand Veatch and Westinghouse for the turnkey construction of a 393 MW coal-fired facility. The contract included an option to build a second twin unit. This option was exercised in August, 1989, when Virginia Power joined Old Dominion as 50% partners in the Clover Project. The partnership agreement stipulates that Old Dominion is responsible for the licensing and construction of the plant and Virginia Power will be responsible for operations

  20. Binaural noise reduction via cue-preserving MMSE filter and adaptive-blocking-based noise PSD estimation

    Science.gov (United States)

    Azarpour, Masoumeh; Enzner, Gerald

    2017-12-01

    Binaural noise reduction, with applications for instance in hearing aids, has been a very significant challenge. This task relates to the optimal utilization of the available microphone signals for the estimation of the ambient noise characteristics and for the optimal filtering algorithm to separate the desired speech from the noise. The additional requirements of low computational complexity and low latency further complicate the design. A particular challenge results from the desired reconstruction of binaural speech input with spatial cue preservation. The latter essentially diminishes the utility of multiple-input/single-output filter-and-sum techniques such as beamforming. In this paper, we propose a comprehensive and effective signal processing configuration with which most of the aforementioned criteria can be met suitably. This relates especially to the requirement of efficient online adaptive processing for noise estimation and optimal filtering while preserving the binaural cues. Regarding noise estimation, we consider three different architectures: interaural (ITF), cross-relation (CR), and principal-component (PCA) target blocking. An objective comparison with two other noise PSD estimation algorithms demonstrates the superiority of the blocking-based noise estimators, especially the CR-based and ITF-based blocking architectures. Moreover, we present a new noise reduction filter based on minimum mean-square error (MMSE), which belongs to the class of common gain filters, hence being rigorous in terms of spatial cue preservation but also efficient and competitive for the acoustic noise reduction task. A formal real-time subjective listening test procedure is also developed in this paper. The proposed listening test enables a real-time assessment of the proposed computationally efficient noise reduction algorithms in a realistic acoustic environment, e.g., considering time-varying room impulse responses and the Lombard effect. The listening test outcome

    This paper comments on The 13th Pacific Basin Nuclear Conference held in Shenzhen, China, on October 21/25, 2002 and summarizes some key papers presented in the Conference and viewpoints from their following discussions, which indicates that nuclear power in the world is once again in the spotlight. The Conference shows that in the coming 50 years the roadmap to develop nuclear energy would be divided into two stages: Near-Term Deployment by 2010-2015, some advanced designs were developed for Utilities; Generation IV Program, its overall goal is to identify and develop next-generation nuclear power systems that could be deployed over the next 30 years to help meet the world's energy needs throughout the 21st century. Some visions is the future, such as co-generation of electricity and space heating or desalination, and combination of Generation IV and so-called Hydrogen Economy-the use of hydrogen in vehicle transport to replace petroleum, were presented. As a primary energy source nuclear power is particularly well suited to hydrogen production, offering the almost unique position of large-scale hydrogen production with near-zero emissions.

  2. Space-variant filtering for correction of wavefront curvature effects in spotlight-mode SAR imagery formed via polar formatting

    Wavefront curvature defocus effects can occur in spotlight- mode SAR imagery when reconstructed via the well-known polar formatting algorithm under certain scenarios that include imaging at close range, use of very low center frequency, and/or imaging of very large scenes. The range migration algorithm, also known as seismic migration, was developed to accommodate these wavefront curvature effects. However, the along-track upsampling of the phase history data required of the original version of range migration can in certain instances represent a major computational burden. A more recent version of migration processing, the frequency domain replication and downsampling (FReD) algorithm, obviates the need to upsample, and is accordingly more efficient. In this paper we demonstrate that the combination of traditional polar formatting with appropriate space-variant post- filtering for refocus can be as efficient or even more efficient than FReD under some imaging conditions, as demonstrated by the computer-simulated results in this paper. The post-filter can be pre-calculated from a theoretical derivation of the curvature effect. The conclusion is that the new polar formatting with post filtering algorithm should be considered as a viable candidate for a spotight-mode image formation processor when curvature effects are present.

  3. Crossreactive T Cells Spotlight the Germline Rules for [alpha beta] T Cell-Receptor Interactions with MHC Molecules

    Dai, Shaodong; Huseby, Eric S.; Rubtsova, Kira; Scott-Browne, James; Crawford, Frances; Macdonald, Whitney A.; Marrack, Philippa; Kappler, John W. (HHMI); (NJMRC)

    2008-10-31

    To test whether highly crossreactive {alpha}{beta} T cell receptors (TCRs) produced during limited negative selection best illustrate evolutionarily conserved interactions between TCR and major histocompatibility complex (MHC) molecules, we solved the structures of three TCRs bound to the same MHC II peptide (IA{sup b}-3K). The TCRs had similar affinities for IA{sup b}-3K but varied from noncrossreactive to extremely crossreactive with other peptides and MHCs. Crossreactivity correlated with a shrinking, increasingly hydrophobic TCR-ligand interface, involving fewer TCR amino acids. A few CDR1 and CDR2 amino acids dominated the most crossreactive TCR interface with MHC, including V{beta}8 48Y and 54E and V{alpha}4 29Y, arranged to impose the familiar diagonal orientation of TCR on MHC. These interactions contribute to MHC binding by other TCRs using related V regions, but not usually so dominantly. These data show that crossreactive TCRs can spotlight the evolutionarily conserved features of TCR-MHC interactions and that these interactions impose the diagonal docking of TCRs on MHC.

  4. Simultaneous determination of environmental α-radionuclides using liquid scintillation counting combined with time interval analysis (TIA) and pulse shape discrimination (PSD)

    1997-01-01

    Some improvements of the detection sensitivity in pulse time interval analysis (TIA) based on selective extraction of successively α-α correlated decay events within millisecond order from random or background events, were established by the utilization of PSD, to reject β/γ-pulses from α-ones and a simple chemical procedure of radium separation, together with the use of well resolved scintillator. By applying the PSD, the contribution of β-decay events was completely eliminated in both the α-spectra and the TIA distribution curves as well as the improvement into clear energy resolution and the enhancement of detection sensitivity for the TIA. As a result, the TIA and α-spectrometric analysis of 226 Ra-extract showed the existence of 223 Ra (Ac-series) and β/α-correlated events with correlated life (due to 0.16 ms due to 214 Bi(β)-> 214 Po(α)->) along with a singly well resolved α-peak to be useful for the determination of 226 Ra (U-series). The difference of half-lives (145 and 1.78 ms) due to 216 Po and 215 Po (direct daughters of 224 Ra for Th-series and 223 Ra for Ac-series, respectively) was also proven for the possibility of the simultaneous determination of both correlated events by using the TIA/PSD combined with chemical separation and liquid scintillation counting method. Finally, the simultaneous determination of three natural decay series, which include U-, Th- and Ac-series nuclides, have been conveniently carried out for some environmental samples using the present method combined with 225 Ra yield tracer (Np-series).

  5. Negative ion MALDI-TOF MS, ISD and PSD of neutral underivatized oligosaccharides without anionic dopant strategies, using 2,5-DHAP as a matrix.

    Oligosaccharides represent complex class of analytes for mass spectrometric analysis due to the high variety of structural isomers concerning glycosidic linkages and possible branching. A systematic study of the negative ion mode matrix-assisted laser desorption/ionization (MALDI) mass spectrometry of various neutral oligosaccharides under selection of an appropriate matrix, like 2,5-dihydroxyacetophenone (2,5-DHAP) is reported here, without commonly used anion dopant strategies. Nevertheless, we were able to generate relevant in-source decay (ISD) cross-ring fragment ions, typically obtained in the negative ion mode. Data observed indicate that the intrinsic property of the terminal non-reduced aldose is crucial for this behavior. A systematic study of the post source decay (PSD) of molecular, pseudomolecular and ISD cross-ring cleavage precursor ions is reported here. A direct comparison of the positive and negative ion mode MALDI MS1 and PSD behavior of neutral oligosaccharides could also be performed under the use of the same matrix preparation, because 2,5-DHAP is fully compatible with positive ion mode acquisition. We found that PSD spectra of deprotonated neutral oligosaccharides obtained in the negative ion mode are richer, because they contained both glycosidic and cross-ring fragment ions. However, we also found that cross-ring fragment ions are readily produced in the positive ion mode when potassiated precursor ions were selected. In addition, we show evidence that non-anionic dopants and specific instrumental parameters can also significantly influence the ISD fragmentation. Taken together, our results should increase our understanding of oligosaccharide behavior in the negative ion mode as well as increase our knowledge regarding many aspects of in-source MALDI chemistry.

    A process is disclosed for producing an article with improved ceramic surface properties including providing an article having a ceramic surface, and placing the article onto a conductive substrate holder in a hermetic enclosure. Thereafter a low pressure ambient is provided in the hermetic enclosure. A plasma including ions of solid materials is produced the ceramic surface of the article being at least partially immersed in a macroparticle free region of the plasma. While the article is immersed in the macroparticle free region, a bias of the substrate holder is biased between a low voltage at which material from the plasma condenses on the surface of the article and a high negative voltage at which ions from the plasma are implanted into the article. 15 figs

  4. Rasagiline meta-analysis: a spotlight on clinical safety and adverse events when treating Parkinson's disease.

    Science.gov (United States)

    Solís-García del Pozo, Julián; Mínguez-Mínguez, Sara; de Groot, Piet W J; Jordán, Joaquín

    2013-07-01

    Rasagiline (Azilect, AGN 1135) is a selective irreversible inhibitor of monoamine oxidase B (MAO-B). MAO-B regulates the brain concentrations of important neurotransmitters that are related to movement, emotion, and cognition. Oral rasagiline, as monotherapy or as adjunctive therapy to levodopa, was effective in the symptomatic treatment of adult patients with Parkinson's disease participating in double-blind, placebo-controlled, international studies. This article reviews the reported adverse effects of rasagiline. A MEDLINE search was performed for all articles from 1990 to present, which reported any adverse effects from rasagiline or related references. We conducted an analysis of the adverse effects of rasagiline based on the reported clinical studies. Furthermore, we compared the incidence of adverse events in clinical trials for rasagiline and placebo. Among the most frequently reported adverse effects for rasagiline as monotherapy are headache, dizziness, and insomnia. Depression, dizziness, somnolence, and other sleep disorders are reported when used in combination therapy. Our analysis demonstrates that the most frequently reported adverse effects in trials did not occur more often with rasagiline than placebo. In conclusion, rasagiline is a well-tolerated MAO-B inhibitor that may help to achieve the desired level of clinical benefit in Parkinson's disease.

  7. Lack of interest in physical activity - individual and environmental attributes in adults across Europe: The SPOTLIGHT project.

    A considerable proportion of European adults report little or no interest in physical activity. Identifying individual-level and environmental-level characteristics of these individuals can help designing effective interventions and policies to promote physical activity. This cross-sectional study additionally explored associations between level of interest and physical activity, after controlling for other individual and environmental variables. Measures of objective and perceived features of the physical environment of residence, self-reported physical activity and other lifestyle behaviors, barriers towards physical activity, general health, and demographics were obtained from 5205 European adults participating in the 2014 online SPOTLIGHT survey. t-Tests, chi-square tests, and generalized estimating equations with negative binomial log-link function were conducted. Adults not interested in physical activity reported a higher BMI and a lower self-rated health, were less educated, and to a smaller extent female and less frequently employed. They were more prone to have less healthy eating habits, and to perceive more barriers towards physical activity. Only minor differences were observed in environmental attributes: the non-interested were slightly more likely to live in neighborhoods objectively characterized as less aesthetic and containing more destinations, and perceived as less functional, safe, and aesthetic. Even after controlling for other individual and environmental factors, interest in physical activity remained a significant correlate of physical activity, supporting the importance of this association. This study is among the first to describe characteristics of individuals with reduced interest in physical activity, suggesting that (lack of) interest is a robust correlate of physical activity in several personal and environmental conditions.

  8. TURNING THE SPOTLIGHT ON CLASS REPRESENTATIVES -EMPIRICAL INSIGHTS FROM DOWN UNDER

    Directory of Open Access Journals (Sweden)

    Jane Caruana

    2012-10-01

    Full Text Available Ten months before Ontario became the first Canadian common law province to authorise American-style class actions, class actions became available in the Federal Court of Australia. In these two countries and in the United States, the named plaintiffs, commonly referred to as class representatives, are the only claimants formally in charge of the litigation, on the plaintiff side, whilst the outcome of class actions binds not only them and their opponents but also the claimants that they represent, the absent class members. And yet, to date, there have been no comprehensive studies of class representatives in these three countries. The aim of this article is to partly address this significant lacuna in the international legal literature by providing the findings of an empirical study, that the authors have undertaken, of the persons that acted as class representatives in the class actions that were filed in the first 17 years of the operation of the class action procedure in the Federal Court of Australia. It is hoped that this article will prompt Canadian scholars to undertake similar studies with respect to Canadian class representatives. Dix mois avant que l’Ontario devienne la première province de common law canadienne à autoriser les recours collectifs à l’américaine, la Cour fédérale d’Australie autorisait ceux-ci. Dans ces deux pays, ainsi qu’aux États-Unis, les demandeurs nommés, communément appelés représentants, sont les seuls demandeurs formellement mêlés au litige du côté de la partie demanderesse, tandis que l’issue des recours collectifs lie non seulement les représentants et leurs adversaires, mais aussi les demandeurs qu’ils représentent, c’est-à-dire les personnes inscrites au recours collectif qui sont absentes. Pourtant, il n’y a eu à ce jour aucune étude approfondie sur ces représentants de groupes dans ces trois pays. L’objet du présent article est de combler en partie cette importante

The first chamber has a contoured periphery to receive articles and the passage is shaped and dimensioned to permit travel therealong only of those articles which are orientated in the first chamber with their longitudinal axes either in the direction of travel or normal to the direction of travel. Articles in other orientations are carried round the first chamber by the rotor for representation at the passage. The rotor in the second chamber permits the passage of those articles which have their longitudinal axes in the direction of travel and topples by means of blades, the articles having their axes normal to the direction of travel into positions in which the axes are in the direction of travel.

    Full Text Available Punita Gupta,1 Gregory M Pastores2 1Division of Genetics, Department of Pediatrics, St. Joseph’s Children’s Hospital, Paterson, New Jersey, USA; 2National Center for Inherited Metabolic Disorders, Mater Misericordiae University Hospital, University College Dublin, Dublin, Ireland Abstract: Gaucher disease (GD is a heritable storage disorder caused by functional defects of the lysosomal acid β-glucosidase and the accumulation of glucosylceramide within macrophages, resulting in multiple organ dysfunction. There are three commercially available enzyme replacement therapy (ERT products for the treatment of GD type 1 (GD1: imiglucerase, velaglucerase alfa, and taliglucerase alfa. Imiglucerase and velaglucerase alfa are produced in different mammalian cell systems; imiglucerase requires postproduction deglycosylation to expose terminal α-mannose residues, which are required for mannose receptor-mediated uptake by target macrophages. These steps are critical to the success of ERT for the treatment of visceral and hematologic manifestations of GD. Taliglucerase alfa is the first US Food and Drug Administration-approved plant-cell-expressed recombinant human protein, using carrot root cell cultures. Furthermore, it does not require postproduction glycosidic modifications. It is indicated for treatment of adults with GD1 in the US, Israel, Australia, Canada, Chile, Brazil, and other countries, and it is additionally approved for the treatment of pediatric patients in the US, Australia, and Canada and for the treatment of hematologic manifestations in pediatric patients with Type 3 GD in Canada and other countries. Our review focuses on the role of taliglucerase alfa in the pediatric population. A literature search through PubMed (from 1995 up till November 2016 of English language articles was performed with the following terms: Gaucher disease, lysosomal storage disease, taliglucerase. Secondary and tertiary references were obtained by reviewing

    A data acquisition system having the various modern electronic devices was designed and tested for practical use of neutron time-of-flight (TOF) measurements with multiple counters. The system is principally composed of TOF logic units (load-able up to 128 units) with a control unit and a conventional micro-computer. The TOF logic unit (main memory, 2048 ch, 24 bits/ch) demonstrates about 1.7 times higher efficiency for neutron counting rate per channel than the one by a conventional TOF logic unit. Meanwhile, some data-access functions of the TOF logic unit were applied to position sensitive analyzer of one-dimensional neutron PSD for small angle scattering. The analyzer was tested with use of pulse generator. The result shows good linearity. (author)

  16. Detection of boiling by Piety's on-line PSD-pattern recognition algorithm applied to neutron noise signals in the SAPHIR reactor

    Spiekerman, G.

    1988-09-01

    A partial blockage of the cooling channels of a fuel element in a swimming pool reactor could lead to vapour generation and to burn-out. To detect such anomalies, a pattern recognition algorithm based on power spectra density (PSD) proposed by Piety was further developed and implemented on a PDP 11/23 for on-line applications. This algorithm identifies anomalies by measuring the PSD on the process signal and comparing them with a standard baseline previously formed. Up to 8 decision discriminants help to recognize spectral changes due to anomalies. In our application, to detect boiling as quickly as possible with sufficient sensitivity, Piety's algorithm was modified using overlapped Fast-Fourier-Transform-Processing and the averaging of the PSDs over a large sample of preceding instantaneous PSDs. This processing allows high sensitivity in detecting weak disturbances without reducing response time. The algorithm was tested with simulation-of-boiling experiments where nitrogen in a cooling channel of a mock-up of a fuel element was injected. Void fractions higher than 30 % in the channel can be detected. In the case of boiling, it is believed that this limit is lower because collapsing bubbles could give rise to stronger fluctuations. The algorithm was also tested with a boiling experiment where the reactor coolant flow was actually reduced. The results showed that the discriminant D5 of Piety's algorithm based on neutron noise obtained from the existing neutron chambers of the reactor control system could sensitively recognize boiling. The detection time amounts to 7-30 s depending on the strength of the disturbances. Other events, which arise during a normal reactor run like scrams, removal of isotope elements without scramming or control rod movements and which could lead to false alarms, can be distinguished from boiling. 49 refs., 104 figs., 5 tabs

  8. Sri Lanka. Spotlight.

    Hoque, M N

    1985-01-01

    Sri Lanka, an island country off the southeastern coast of India, populated by an estimated 16.1 million inhabitants, was one of the 1st developing countries to adopt a population policy aimed at reducing population growth and redistributing the population more equitably throughout the country. Population density is high. There are 636 persons/square mile, and 2/3 of the population lives in the southwestern and central regions of the country. Government redistribution policies seek to increase internal migration flows to the drier and less populated areas. The country's birth rate was 27 in 1982, the death rate was 6 in 1981, and the infant mortality rate was 34.4 in 1980. The rate of natural increase in 1982 was 2.1%, and the population growth rate declined from 2.5% prior to 1970 to 1.7% in 1980. The total fertility rate declined between 1963-74 from 5.0-3.4 and then increased to 3.7 in recent years. Given the age structure of the population, the population is expected to continue growing at a high rate in the coming years; however, the age at marriage is increasing and the proportion of young married women in the population is declining, and these trends will have an impact on population growth. These trends are due in part to increased educational and employment opportunities for women. The delay in marriage may also be linked to the dowry system. Given the high rate of poverty, it is difficult for parents to accummulate sufficient resources to provide dowries for their daughters. Sri lanka's economy is predominantly agricultural, with only 15% of the gross national product derived from manufacturing. Approximately 22% of thepopulation lives in urban areas. In 1981 exports totaled US$1.1 billion, and major export items were tea and rubber. In the same year, imports totaled US$1.8 billion and consisted primarily of food, petroleum, and fertilizers. The per capita gross national product was US$320 in 1982. Sri Lanka receives considerable foreign aid, and the country's family planning program receives substantial outside support.

    2000-10-01

    CERN, ESA and ESO Put Physics On Stage [1] Summary Can you imagine how much physics is in a simple match of ping-pong, in throwing a boomerang, or in a musical concert? Physics is all around us and governs our lives. The World-Wide Web and mobile communication are only two examples of technologies that have rapidly found their way from science into the everyday life. [Go to Physics On Stage Website at CERN] But who is going to maintain these technologies and develop new ones in the future? Probably not young Europeans, as recent surveys show a frightening decline of interest in physics and technology among Europe's citizens, especially schoolchildren. Fewer and fewer young people enrol in physics courses at university. The project "Physics on Stage" tackles this problem head on. An international festival of 400 physics educators from 22 European countries [2] gather at CERN in Geneva from 6 to 10 November to show how fascinating and entertaining physics can be . In a week-long event innovative methods of teaching physics and demonstrations of the fun that lies in physics are presented in a fair, in 10 spectacular performances, and presentations. Workshops on 14 key themes will give the delegates - teachers, professors, artists and other physics educators - the chance to discuss and come up with solutions for the worrying situation of disenchantment with Science in Europe. The European Science and Technology Week 2000 "Physics on Stage" is a joint project organised by the European Organisation for Nuclear Research (CERN) , the European Space Agency (ESA) and the European Southern Observatory (ESO) , Europe's leading physics research organisations. This is the first time that these three organisations have worked together in such close collaboration to catalyse a change in attitude towards science and technology education. Physics on Stage is funded in part by the European Commission and happens as an event in the European Science and Technology Week 2000, an initiative of the EC to raise public awareness of science and technology. Other partners are the European Physical Society (EPS) and the European Association for Astronomy Education (EAAE). European Commissioner Busquin to Visit Physics On Stage On Thursday, November 9, Philippe Busquin , Commissioner for Research, European Commission, Prof. Luciano Maiani , Director-General of CERN, Antonio Rodota , Director-General of ESA, Dr. Catherine Cesarsky , Director-General of ESO, and Dr. Achilleas Mitsos , Director-General of the Research DG in the European Commission, will participate in the activities of the Physics on Stage Festival. On this occasion, Commissioner Busquin will address conference delegates and the Media on the importance of Science and of innovative science and technology education. The Festival Each of the more than 400 delegates of the festival has been selected during the course of the year by committees in each of the 22 countries for outstanding projects promoting science. For example, a group of Irish physics teachers and their students will give a concert on instruments made exclusively of plumbing material, explaining the physics of sound at the same time. A professional theatre company from Switzerland stages a play on antimatter. Or two young Germans invite spectators to their interactive physics show where they juggle, eat fire and perform stunning physics experiments on stage. The colourful centrepiece of this week is the Physics Fair. Every country has its own stands where delegates show their projects, programmes or experiments and gain inspiration from the exhibits from other countries. Physics on Stage is a unique event. Nothing like it has ever happened in terms of international exchange, international collaboration and state of the art science and technology education methods. The Nobel prizewinners of 2030 are at school today. What ideas can Europe's teachers put forward to boost their interest in science? An invitation to the media We invite journalists to take part in this both politically and visually interesting event. We expect many useful results from this exchange of experience, there will a large choice of potential interview partners and of course uncountable images and impressions.

  13. SPOTLIGHTING ENGLISH PHRASAL VERBS

    Directory of Open Access Journals (Sweden)

    Éva Kovács

    2014-03-01

    Full Text Available Phrasal verbs or multi-word verbs, such as call off, go into and run up against, etc. represent a very interesting and challenging aspect of the English language. In ELT there is a widespread view that familiarity with a wide range of phrasal verbs and the ability to use them appropriately in context are among the distinguishing marks of a native-like command of English. However, it is also generally recognised that these verb+particle combinations pose special difficulties for both learners and teachers of English partly because there are so many of them, partly because they have special semantic, syntactic and stylistic properties. Besides, quite many of them can be used as nouns, e.g. a hideaway, a stowaway and a write-off, etc. and adjectives, e.g. a broken-down car and a knockdown price, etc. What is more, again quite many of them have a single word equivalent of Romance origin, which, however, often differs from them in terms of style, collocation and meaning, e.g. blow up ~ explode, do away with ~ eliminate and put out ~ extinguish, etc. Furthermore, it is a misconception that phrasal verbs are mainly used in informal style and in spoken English. In fact, they can be found in many styles of writing, ranging from highly formal texts to slang, e.g. call forth vs. gobble up, etc. This paper sets out to explore the unique and complex nature of English verb+particle constructions in order to make them a more manageable part of the vocabulary of English.

  17. Costa Rica. Spotlight.

    Haub, C; Adams, J

    1985-05-01

    Costa Rica's demographic and economic characteristics are highlighted. Costa Rica's demographic situation is unique in certain respects. Between the late 1950s and the late 1970s, the total fertility rate declined from about 7 to 4 and then stabilized instead of continuing to decline to 2 as expected. This is especially surprising since the level of contraceptive use is similar to that of most European countries. Approximately 2/3 of all couples practice contraception. It is possible that the rate will slowly decline to the expected level, but a delayed decline will ultimately produce a much larger population than initially expected. The demographic situation in Costa Rica is being carefully monitored for insights which might be useful in predicting future fertility patterns in other developing countries. The government of Costa Rica recognizes that family planning is a necessary component of maternal and child health care; however, most family planning services are provided by private organizations. In 1982, population size was 2.6 million, the crude birth rate was 30.7, the crude death rate was 3.9, infant mortality was 19.3, and the rate of natural increase was 2.7%. The population is predominantly Spanish, and the indigenous population totals only 20,000. 48% of the population is urban. Costa Rica has a relatively stable deomocratic government. It relationshiops with other countries are generally peaceful, but tensions between Nicaragua and Costa Rica are increasing. The country's economic situation deteriorated in recent years due primarily to a decline in the price of coffee, the country's principle export commodity. The trade deficit increased markedly, unemployment increased, and income fell sharply. The economic slowdown is now showing signs of a reversal. In 1983 exports, consisting primarily of coffee, bananas, beef, sugar, cane and cacao, totalled US$871 million, and imports, consisting mainly of manufactured goods and equipment, chemicals, fuel, food, and fertilizer, amounted to US$870 million. In 1983 the per capita gross national product was US$1020.

  18. Spotlight on Peru.

    Science.gov (United States)

    1997-01-01

    Lima's population grew from 1 million to 7 million during 1969-89, almost entirely due to rural-urban immigration. Other urban areas such as Iquitos experienced similar growth over the period. National, regional, and municipal governments have been working to restore civil order in the country and to bring basic health, sanitation, and education programs to the population. However, language, attitudinal, and cultural differences impede progress in this diverse and changing country. Peru's young population of median age 21 years presents a challenge to the development and implementation of effective reproductive health care programs for the country. Pathfinder's work in Peru is helped by current President Alberto Fujimori's strong and active support for family planning. In the face of strong opposition from the Roman Catholic Church, President Fujimori has held onto his conviction and commitment to reduce levels of maternal morbidity and mortality in Peru by increasing the accessibility of family planning programs. Pathfinder's work in Peru with the US Agency for International Development (USAID) includes the 5-year program Project 2000 designed to improve maternal and child health in 12 priority regions of the country. Pathfinder is also working with USAID to link family planning to postpartum services in 30 public hospitals throughout the country. New programs will be launched with contributions from individuals and foundations.

    To describe the design, methods and first results of a survey on obesity-related behaviours and body mass index (BMI) in adults living in neighbourhoods from five urban regions across Europe. A cross-sectional observational study in the framework of an European Union-funded project on obesogenic environments (SPOTLIGHT). 60 urban neighbourhoods (12 per country) were randomly selected in large urban zones in Belgium, France, Hungary, the Netherlands and the UK, based on high or low values for median household income (socioeconomic status, SES) and residential area density. A total of 6037 adults (mean age 52 years, 56% female) participated in the online survey. Self-reported physical activity, sedentary behaviours, dietary habits and BMI. Other measures included general health; barriers and motivations for a healthy lifestyle, perceived social and physical environmental characteristics; the availability of transport modes and their use to specific destinations; self-defined neighbourhood boundaries and items related to residential selection. Across five countries, residents from low-SES neighbourhoods ate less fruit and vegetables, drank more sugary drinks and had a consistently higher BMI. SES differences in sedentary behaviours were observed in France, with residents from higher SES neighbourhoods reporting to sit more. Residents from low-density neighbourhoods were less physically active than those from high-density neighbourhoods; during leisure time and (most pronounced) for transport (except for Belgium). BMI differences by residential density were inconsistent across all countries. The SPOTLIGHT survey provides an original approach for investigating relations between environmental characteristics, obesity-related behaviours and obesity in Europe. First descriptive results indicate considerable differences in health behaviours and BMI between countries and neighbourhood types. Published by the BMJ Publishing Group Limited.

  2. Finding and Recommending Scholarly Articles

    Kurtz, Michael J.; Henneken, Edwin A.

    2014-05-01

    The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

  3. Estimation of PSD shifts for high-resolution metrology of thickness micro-changes with possible applications in vessel walls and biological membrane characterization.

    Achieving accurate measurements of inflammation levels in tissues or thickness changes in biological membranes (e.g., amniotic sac, parietal pleura) and thin biological walls (e.g., blood vessels) from outside the human body, is a promising research line in the medical area. It would provide a technical basis to study the options for early diagnosis of some serious diseases such as hypertension, atherosclerosis or tuberculosis. Nevertheless, achieving the aim of non-invasive measurement of those scarcely-accessible parameters on patient internal tissues, currently presents many difficulties. The use of high-frequency ultrasonic transducer systems appears to offer a possible solution. Previous studies using conventional ultrasonic imaging have shown this, but the spatial resolution was not sufficient so as to permit a thickness evaluation with clinical significance, which requires an accuracy of a few microns.

    Full Text Available Achieving accurate measurements of inflammation levels in tissues or thickness changes in biological membranes (e.g., amniotic sac, parietal pleura and thin biological walls (e.g., blood vessels from outside the human body, is a promising research line in the medical area. It would provide a technical basis to study the options for early diagnosis of some serious diseases such as hypertension, atherosclerosis or tuberculosis. Nevertheless, achieving the aim of non-invasive measurement of those scarcely-accessible parameters on patient internal tissues, currently presents many difficulties. The use of high-frequency ultrasonic transducer systems appears to offer a possible solution. Previous studies using conventional ultrasonic imaging have shown this, but the spatial resolution was not sufficient so as to permit a thickness evaluation with clinical significance, which requires an accuracy of a few microns. In this paper a broadband ultrasonic technique, that was recently developed by the authors to address other non-invasive medical detection problems (by integrating a piezoelectric transducer into a spectral measuring system, is extended to our new objective; the aim is its application to the thickness measurement of sub-millimeter membranes or layers made of materials similar to some biological tissues (phantoms.

  9. Earthquake-Induced Building Damage Detection with Post-Event Sub-Meter VHR TerraSAR-X Staring Spotlight Imagery

    Directory of Open Access Journals (Sweden)

    Lixia Gong

    2016-10-01

    Full Text Available Compared with optical sensors, Synthetic Aperture Radar (SAR can provide important damage information due to its ability to map areas affected by earthquakes independently from weather conditions and solar illumination. In 2013, a new TerraSAR-X mode named staring spotlight (ST, whose azimuth resolution was improved to 0.24 m, was introduced for various applications. This data source made it possible to extract detailed information from individual buildings. In this paper, we present a new concept for individual building damage assessment using a post-event sub-meter very high resolution (VHR SAR image and a building footprint map. With the building footprint map, the original footprints of buildings can be located in the SAR image. Based on the building imaging analysis of a building in the SAR image, the features in the building footprint can be extracted to identify standing and collapsed buildings. Three machine learning classifiers, including random forest (RF, support vector machine (SVM and K-nearest neighbor (K-NN, are used in the experiments. The results show that the proposed method can obtain good overall accuracy, which is above 80% with the three classifiers. The efficiency of the proposed method is demonstrated based on samples of buildings using descending and ascending sub-meter VHR ST images, which were all acquired from the same area in old Beichuan County, China.

  10. Application of the EGM Method to a LED-Based Spotlight: A Constrained Pseudo-Optimization Design Process Based on the Analysis of the Local Entropy Generation Maps

    Directory of Open Access Journals (Sweden)

    Enrico Sciubba

    2011-06-01

    Full Text Available In this paper, the entropy generation minimization (EGM method is applied to an industrial heat transfer problem: the forced convective cooling of a LED-based spotlight. The design specification calls for eighteen diodes arranged on a circular copper plate of 35 mm diameter. Every diode dissipates 3 W and the maximum allowedtemperature of the plate is 80 °C. The cooling relies on the forced convection driven by a jet of air impinging on the plate. An initial complex geometry of plate fins is presented and analyzed with a commercial CFD code that computes the entropy generation rate. A pseudo-optimization process is carried out via a successive series of design modifications based on a careful analysis of the entropy generation maps. One of the advantages of the EGM method is that the rationale behind each step of the design process can be justified on a physical basis. It is found that the best performance is attained when the fins are periodically spaced in the radial direction.

    Despotović, Nebojsa; Milosević, Dragoslav P; Erceg, Predrag; Davidović, Mladen

    2009-01-01

    Population aging is a feature of all countries in the world. According to statistics, the Republic of Serbia is one of the countries with the majority of the elderly. Taking this into account, are articles on the elderly well represented in domestic medical journals? The aim of the paper was to determine whether there was a sufficient number of articles on the elderly in domestic medical journals. The articles on the elderly were searched using search engines in domestic and foreign medical journals for the last 5 years compared with the number of articles on children in the same publications for the same period. In the Serbian Citation Index, 11 articles on the topic of the elderly, and 487 on children were registered. In Srpski arhivza celokupno lekarstvo, there was registered only one article on the topic of the elderly, and 30 on children. In Vojnosanitetskipregled, 2 articles on the elderly and 13 on children were registered (p articles on the elderly and 759 articles on children; in the JAMA, there were 63 articles on the elderly and 303 articles on children; and in The Lancet, in the last five years, 46 articles on the elderly and 148 articles on children were published. The themes of the elderly were rarely represented in Serbian medical journals.This has reduced the interest of physicians in medical problems of this growing population of patients and further sent them away from making standards in the diagnosis and treatment of the elderly.

    The information concerning the interchangeability of medical articles is highly valuable because it makes it possible to correlate most precisely medical articles with medical technologies and medical care standards and to optimize budget costs under public purchasing. The proposed procedure of determination of interchangeability is based on criteria of equivalence of prescriptions, functional technical and technological characteristics and effectiveness of functioning of medical articles.

  11. Measuring the Interestingness of News Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

    In the last 30 years lung transplantation has proven to be a lifesaving therapeutic option for patients with end-stage lung disease. The objective of this study was to perform a bibliometric analysis of lung transplantation research articles. A bibliometric evaluation of the evolution of scientific production in the field of lung transplantations between 1989 and 2009 was conducted using the ISI Web of Science. The search terms selected were "lung transplant" OR "pulmonary transplant". Specific features including year of publication, language, geographical distribution, first author, main journal publishing these articles, journals publishing highly cited articles, and institutional affiliation were analyzed. The citation characteristics of articles were additionally analyzed. A total of 6409 (58.0 %) research articles were found. The time trend of the number of articles showed an increase of more than 6.81 between 1989 and 2009. North America contributed 50.4 % and Europe contributed 46.0 % of published articles. The greatest number of contributions came from the USA (43.6 %), followed by England (9.1 %) and Germany (8.6 %). There were 104 522 citations of these articles by 25 July 2010. The average citation per article was 16.31. The New England Journal of Medicine ranked first with regard to the number of articles and the number of highly cited articles. G. A. Patterson, Washington University, and the US National Institutes of Health (NIH) were the top author, institution and funding agency, respectively. The number of publications and the scientific interest in lung transplantation has increased rapidly in recent years. Citations of articles published in the field of lung transplantation are increasing and the numbers of uncited articles are fewer compared to the average citations of articles and uncited articles in the field of medicine. © Georg Thieme Verlag KG Stuttgart · New York.

    2014-04-01

    To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the

  15. High resolution deformation maps of Volcán de Colima, Mexico, derived from a year-long TerraSAR-X Spotlight time series

    Science.gov (United States)

    Salzer, Jacqueline; Nikkhoo, Mehdi; Walter, Thomas R.

    2015-04-01

    Volcán de Colima is a steep sloped explosive stratovolcano located in southern Central Mexico, and one of the most active volcanoes in North America. Major recent historical eruptions occured in 1818 (VEI 4) and 1913 (VEI 5), which removed several hundred meters from the summit of the volcanic edifice [1], and point towards the activity being marked by 100-year cycles which terminate in a large Plinian eruption. Also, five large flank collapse events have been identified during the Holocene [2]. Since the beginning of the most recent eruptiove period in 1998, the type of activity has been varying between predominantly explosive, dome building and dome collapse. Between 2007 and 2011, the activity at Colima was characterized by dome extrusion. The volcano then entered a period of low activity, which lasted until January 2013, when a series of explosions took place which initiated a new, still ongoing period of dome growth. The historical eruption of 1913, as well as the renewal of the activity in 2013, were both preceeded by longer periods of low activity, and only very limited short term precursors. The year 2012 at Volcán de Colima is therefore a good example to study volcanic activity in periods of quiescence, but leading up to an eruption. Furthermore, the possibility of a larger event in the future make it a particularly important volcano to study. We have acquired TerraSAR-X data in spotlight mode for ascending and descending tracks over Colima, obtaining a high spatial resolution of up to 2 m, and a temporal resolution of up to 11 days. Here we present the time series of the dome deformation between February and December 2012. We generated interferograms using an updated version of DORIS, accounting for the doppler variation in along track direction [3] and subsequently analysed the time series of the deformation pattern with the small baseline - persistent scatterer (PS) approach implemented in the StaMPS software. We removed the topographically correlated

  16. From the Margins to the Spotlight: Diverse Deaf and Hard of Hearing Student Populations and Standardized Assessment Accessibility.

    Cawthon, Stephanie

    2015-01-01

    Designing assessments and tests is one of the more challenging aspects of creating an accessible learning environment for students who are deaf or hard of hearing (DHH), particularly for deaf students with a disability (DWD). Standardized assessments are a key mechanism by which the educational system in the United States measures student progress, teacher effectiveness, and the impact of school reform. The diversity of student characteristics within DHH and DWD populations is only now becoming visible in the research literature relating to standardized assessments and their use in large-scale accountability reforms. The purpose of this article is to explore the theoretical frameworks surrounding assessment policy and practice, current research related to standardized assessment and students who are DHH and DWD, and potential implications for practice within both the assessment and instruction contexts.

  17. Apparatus for controlling the conveyance of articles

    International Nuclear Information System (INIS)

    Billington, A.J.; Rice, T.G.

    1987-01-01

    A selector mechanism for controlling transfer of articles from a plurality of upstream feed lines to at least one downstream feed line comprises a plurality of transfer passages each provided with a gate and at least one stop. The gates are operable to block the leading article in the respective transfer passages while the stops are operable to arrest movement of a trailing article and hence the articles that follow it. Operation of the gates and stops is co-ordinated so that the stops are operative when the gates are operated to unblock the leading article. In this way, the number of articles freed for onward movement each time the gates are operated to unblock the path of conveyance can be controlled. (author)

    2012-10-01

    Spine-related research has evolved dramatically during the last century. Significant contributions have been made by thousands of authors. A citation rank list has historically been used within a particular field to measure the importance of an article. The purpose of this article is to report on the 100 most cited articles in the field of spine. Science Citation Index Expanded was searched for citations in 27 different journals (as of 30 November 2010) chosen based on the relevance for all cited spine publications. The top 100 most cited articles were identified. Important information such as journal, date, country of origin, author, subspecialty, and level of evidence (for clinical research) were compiled. The top 100 publications ranged from 1,695 to 240 citations. Fifty-three articles were of the lumbar, 17 were of the thoracolumbar, and 15 of the cervical spine. Eighty-one of the articles were clinical and 19 were basic science in nature. Level of evidence varied for the clinical papers, however, was most commonly level IV (34 of 81 articles). Notably, the 1990-1999 decade was the most productive period with 43 of the top 100 articles published during this time. Identification of the most cited articles within the field of spine recognizes some of the most important contributions in the peer-reviewed literature. Current investigators may utilize the aspects of their work to guide and direct future spine-related research.
