  9. Multi-Line Quiet Sun Spectro-Polarimetry at 5250 and 6302 \\AA

    The reliability of quiet Sun magnetic field diagnostics based on the \\ion{Fe}{1} lines at 6302 \\AA has been questioned by recent work. We present here the results of a thorough study of high-resolution multi-line observations taken with the new spectro-polarimeter SPINOR, comprising the 5250 and 6302 \\AA spectral domains. The observations were analyzed using several inversion algorithms, including Milne-Eddington, LTE with 1 and 2 components, and MISMA codes. We find that the line-ratio technique applied to the 5250 \\AA lines is not sufficiently reliable to provide a direct magnetic diagnostic in the presence of thermal fluctuations and variable line broadening. In general, one needs to resort to inversion algorithms, ideally with realistic magneto-hydrodynamical constrains. When this is done, the 5250 \\AA lines do not seem to provide any significant advantage over those at 6302 \\AA . In fact, our results point towards a better performance with the latter (in the presence of turbulent line broadening). In any...

  16. Development of a fast multi-line x-ray CT detector for NDT

    Typical X-ray detectors for non-destructive testing (NDT) are line detectors or area detectors, like e.g. flat panel detectors. Multi-line detectors are currently only available in medical Computed Tomography (CT) scanners. Compared to flat panel detectors, line and multi-line detectors can achieve much higher frame rates. This allows time-resolved 3D CT scans of an object under investigation. Also, an improved image quality can be achieved due to reduced scattered radiation from object and detector themselves. Another benefit of line and multi-line detectors is that very wide detectors can be assembled easily, while flat panel detectors are usually limited to an imaging field with a size of approx. 40 × 40 cm2 at maximum. The big disadvantage of line detectors is the limited number of object slices that can be scanned simultaneously. This leads to long scan times for large objects. Volume scans with a multi-line detector are much faster, but with almost similar image quality. Due to the promising properties of multi-line detectors their application outside of medical CT would also be very interesting for NDT. However, medical CT multi-line detectors are optimized for the scanning of human bodies. Many non-medical applications require higher spatial resolutions and/or higher X-ray energies. For those non-medical applications we are developing a fast multi-line X-ray detector.In the scope of this work, we present the current state of the development of the novel detector, which includes several outstanding properties like an adjustable curved design for variable focus-detector-distances, conserving nearly uniform perpendicular irradiation over the entire detector width. Basis of the detector is a specifically designed, radiation hard CMOS imaging sensor with a pixel pitch of 200 μ m. Each pixel has an automatic in-pixel gain adjustment, which allows for both: a very high sensitivity and a wide dynamic range. The final detector is planned to have 256 lines of

    An improved photoconductive semiconductor switch comprises multiple-line optical triggering of multiple, high-current parallel filaments between the switch electrodes. The switch can also have a multi-gap, interdigitated electrode for the generation of additional parallel filaments. Multi-line triggering can increase the switch lifetime at high currents by increasing the number of current filaments and reducing the current density at the contact electrodes in a controlled manner. Furthermore, the improved switch can mitigate the degradation of switching conditions with increased number of firings of the switch.

    2004-09-01

    Full Text Available Abstract Background We developed a method to make a various high quality random peptide libraries for evolutionary protein engineering based on a combinatorial DNA synthesis. Results A split synthesis in codon units was performed with mixtures of bases optimally designed by using a Genetic Algorithm program. It required only standard DNA synthetic reagents and standard DNA synthesizers in three lines. This multi-line split DNA synthesis (MLSDS is simply realized by adding a mix-and-split process to normal DNA synthesis protocol. Superiority of MLSDS method over other methods was shown. We demonstrated the synthesis of oligonucleotide libraries with 1016 diversity, and the construction of a library with random sequence coding 120 amino acids containing few stop codons. Conclusions Owing to the flexibility of the MLSDS method, it will be able to design various "rational" libraries by using bioinformatics databases.

    2016-04-01

    A multi-line internal standard calibration method is proposed for the quantitative analysis of carbon steel using laser-induced breakdown spectroscopy (LIBS). A procedure based on the method was adopted to select the best calibration curves and the corresponding emission lines pairs automatically. Laser-induced breakdown spectroscopy experiments with carbon steel samples were performed, and C, Cr, and Mn were analyzed via the proposed method. Calibration curves of these elements were constructed via a traditional single line internal standard calibration method and a multi-line internal standard calibration method. The calibration curves obtained were evaluated with the determination coefficient, the root mean square error of cross-validation, and the average relative error of cross-validation. All of the parameters were improved significantly with the proposed method. The results show that accurate and stable calibration curves can be obtained efficiently via the multi-line internal standard calibration method. © The Author(s) 2016.

  13. Range estimation by Doppler of multi-line in radiated noise spectrum

    Institute of Scientific and Technical Information of China (English)

    WU Guoqing; MA Li

    2005-01-01

    A method by applying Doppler frequency shift of multi-line in radiated noise spectrum to estimate the vertical range from a receiver to a moving vessel, which is supposed to move along a straight line at a constant velocity, is developed. This method is based on passive ranging by a single sensor and the depth of the sea and other environment parameters are not necessarily known. First the Wigner-Ville distribution is used as the instantaneous frequency estimator to find out the instantaneous frequencies of the muti-lines as a signal. Then define Doppler frequency shift basis functions, based on an algorithm called matching pursuit, by a searching strategy of variable span, and explore the minimum spatial distance between the signal and the Doppler frequency shift basis functions in a five-dimension space. The basis function of the obtained minimum spatial distance corresponds to the estimation of range and speed of the moving vessel. Computer simulations yield statistics errors in the range and speed estimates with differing intensities of noise. If the white noise deviation is less than 10% of the maximum Doppler frequency shift and time-window width is 1.47 times of reference-duration,relative error of range estimate is less than 5.4% and relative error of speed estimate is less than 1.4%. This estimation method has been tested and the result conforms to data collected during an experiment on the sea, the estimated speed is 52 knots and the estimated range is 42 m. The single point passive ranging method can be used for ranging purposes in sonar-buoys, mines,movement analysis of an underwater object in underwater acoustics experiment, and sound source level measurements.

  14. Acoustic output of multi-line transmit beamforming for fast cardiac imaging: a simulation study.

    Achieving higher frame rates in cardiac ultrasound could unveil short-lived myocardial events and lead to new insights on cardiac function. Multi-line transmit (MLT) beamforming (i.e., simultaneously transmitting multiple focused beams) is a potential approach to achieve this. However, two challenges come with it: first, it leads to cross-talk between the MLT beams, appearing as imaging artifacts, and second, it presents acoustic summation in the near field, where multiple MLT beams overlap. Although several studies have focused on the former, no studies have looked into the implications of the latter on acoustic safety. In this paper, the acoustic field of 4-MLT was simulated and compared with single-line transmit (SLT). The findings suggest that standard MLT does present potential concerns. Compared with SLT, it shows a 2-fold increase in mechanical index (MI) (from 1.0 to 2.3), a 6-fold increase in spatial-peak pulse-average intensity (I(sppa)) (from 99 to 576 W∙cm(-2)) and a 12-fold increase in spatial-peak temporalaverage intensity (I(spta)) (from 119 to 1407 mW∙cm(-2)). Subsequently, modifications of the transmit pulse and delay line of MLT were studied. These modifications allowed for a change in the spatio-temporal distribution of the acoustic output, thereby significantly decreasing the safety indices (MI = 1.2, I(sppa) = 92 W∙cm(-2) and I(spta) = 366 mW∙cm(-2)). Accordingly, they help mitigate the concerns around MLT, reducing potential tradeoffs between acoustic safety and image quality.

  15. On a family of KP multi-line solitons associated to rational degenerations of real hyperelliptic curves and to the finite non-periodic Toda hierarchy

    Science.gov (United States)

    Abenda, Simonetta

    2017-09-01

    We continue the program started in Abenda and Grinevich (2015) of associating rational degenerations of M-curves to points in GrTNN(k , n) using KP theory for real finite gap solutions. More precisely, we focus on the inverse problem of characterizing the soliton data which produce Krichever divisors compatible with the KP reality condition when Γ is a certain rational degeneration of a hyperelliptic M-curve. Such choice is motivated by the fact that Γ is related to the curves associated to points in GrTP(1 , n) and in GrTP(n - 1 , n) in Abenda and Grinevich (2015). We prove that the reality condition on the Krichever divisor on Γ singles out a special family of KP multi-line solitons (T-hyperelliptic solitons) in GrTP(k , n) , k ∈ [ n - 1 ] , naturally connected to the finite non-periodic Toda hierarchy. We discuss the relations between the algebraic-geometric description of KP T-hyperelliptic solitons and of the open Toda system. Finally, we also explain the effect of the space-time transformation which conjugates soliton data in GrTP(k , n) to soliton data in GrTP(n - k , n) on the Krichever divisor for such KP solitons.

  20. SiO multi-line laser-induced fluorescence for quantitative temperature imaging in flame-synthesis of nanoparticles

    Science.gov (United States)

    Chrystie, Robin S. M.; Feroughi, Omid M.; Dreier, Thomas; Schulz, Christof

    2017-04-01

    Silicon monoxide (SiO) is an intermediate in the gas-phase synthesis of SiO2 nanoparticles and coatings. We demonstrate a method for in situ imaging the gas-phase temperature via multi-line laser-induced fluorescence (LIF) using excitation in the A 1Π- X 1Σ+(0,0) band near 235 nm. A low-pressure lean (3 kPa, φ = 0.39) premixed hydrogen/oxygen flame was seeded with 210 ppm hexamethyldisiloxane (HMDSO) to produce SiO2 nanoparticles. Spectral regions with no interference from other species in the flame were located, and the excitation-spectral range that provides the best temperature sensitivity was determined from numerical experiments. Quenching rates of the selected transitions were also determined from fluorescence lifetime measurements, and found to be independent of the excited rotational state. Upon laser light-sheet excitation, images of fluorescence were recorded for a sequence of excitation wavelengths and pixel-wise multi-line fitting of the spectra yields temperature images. The results were compared against multi-line NO-LIF temperature imaging measurements using the A 2Σ+- X 2Π(0,0) band near 225 nm from 500 ppm NO added to the gas flow as a thermometry target. Both methods show good qualitative agreement with each other and demonstrate that temperature can be evaluated from the zone in the reactor where SiO is naturally present without adding tracers. SiO LIF exhibited high signal-to-noise ratios of the order of ten times that of NO LIF.

    Baudelot, Christian

    2017-04-01

    Treating suicide as a social fact means disregarding its individual and dramatic dimensions. Sociologists do not reason on the basis of specific cases but by studying the variations, in space and time, of suicide rates. Their contribution relates essentially to a renewed perspective on society: suicide is in fact a very accurate indicator of the intensity and quality of the bonds which unite or isolate individuals in a society.

    Full Text Available Examination of microscopic sections of animal tissues reveals facts which are not always related to its normal histology or pathology. Processing of tissue specimens consists of lengthy procedures from the stage of surgical removal to the stained and mounted microscopic sections. Defects are common in tissue sections as a result of faulty procedures. These defects are referred to as artifacts. They lead to misinterpretation of histopathological diagnosis but at times they throw limelight into diagnosis. This paper attempts to put together all the facts regarding the various artifacts that are encountered in histopathology.

    Arterial vascular diseases comprise the leading cause of death in the industrialized world. Every physician learns about the pathology of these diseases in medical school. All pathologists evaluate arterial disease in surgical pathology and/or autopsy specimens. All clinicians encounter patients with clinical manifestations of these diseases. With such a common and clinically-important group of entities one would think there would be a general understanding of the "known" information that exists. That is, physicians and scientists should be able to separate what is fact and what is fancy. This review article is intended to generate thought in this regard.

    The FACT collaboration operates an imaging air-Cherenkov telescope on La Palma optimized for monitoring bright blazars. Recently, the collaboration reported a technological breakthrough. For the first time, avalanche photo diodes operated in Geiger mode have been employed in the camera. The low power consumption, high quantum efficiency, and high reliability of the novel semi-conductor based camera is the key to robotic operation needed for monitoring. Moreover, linearity permits observations even during moon light. Analysis of gamma-ray lightcurves of blazars holds the key to understand particle acceleration and its relation to the central engine.

    At a time of fake news, hacks, leaks, and unverified reports, many people are unsure whom to believe. How can we communicate in ways that make individuals question their assumptions and learn? My colleagues at The Hastings Center and many journalists and scientists are grappling with this question and have, independently, reached the same first step: recognize that facts can't be fully understood without probing their connection to values. "Explaining the basics is important, of course, but we also need to diversify our approach to the coverage of science-particularly as it intersects with the matrix of cultural, religious, social, and political values of our readers," said an article in Undark, an online magazine of science journalism. An editorial in Nature called for scientists to engage directly with citizens in debates over climate change and genome editing, noting that "the ethical issues can be critically dependent on the science, for example, in understanding where the boundaries between non-heritable and heritable genome modifications might be." We're here to help. © 2017 The Hastings Center.

    Successful merger of state-of-the-art, semiconductor quantum-cascade lasers (QCL), with the mature CO2 laser technology, resulted in a delivery of highly-desired qualities of CO2 laser output that were not available previously without much effort. These qualities, such as multi-line operation, excellent spectro-temporal stability and pulse waveform control, became available from a single device of moderate complexity. This paper describes the operation principle and the unique properties of the solid{state seeded CO2 laser, invented for an application in laser-produced-plasma (LPP), extreme-UV (EUV) light source.

    Here we argue that the essence of institutional facts is status functions. Humans recognize these functions which contain a set of deontic powers through collective intentionality. Therefore, institutional facts are ontologically subjective and epistemologically objective. Nevertheless, objectivity of institutional facts totally depends on language which itself is a fundamental institution for other institutions.

  18. Strain: Fact or Fiction?

    Science.gov (United States)

    Heilbronner, Renée

    2017-04-01

    2017 marks the 50th anniversary of the publication of John Ramsay's well known textbook "Folding and Fracturing of Rocks" - ... and the 30th anniversary of the rejection of a rather less well known paper entitled "Strain: Fact or Fiction?" submitted by Renée Panozzo to the Journal of Structural Geology. The gist of the paper was simple and straight forward: it was argued that not every fabric that can be observed in deformed rocks is necessarily a measure of the amount of strain the rock incurred. A distinction was made between a general "fabric", i.e., the traceable geometry of grain boundaries, for example, and a so-called "strain fabric", i.e., the model geometry that would result from homogeneously straining an initially isotropic fabric and that would exhibit at least orthorhombic symmetry. To verify if a given fabric was indeed a strain fabric it was therefore suggested to use the SURFOR method (published by Panozzo) and to carry out a so-called strain test, i.e., a check of symmetry, before interpreting the results of a fabric analysis in terms of strain. The problem with the paper was that it was very obviously written out of frustration. The frustration came form having reviewed a number of manuscripts which tried to use the then novel SURFOR method for strain analysis without first checking if the the fabric was a indeed a "strain fabric" or not, and then blaming the SURFOR method for producing ambiguous results. As a result, the paper was not exactly well balanced and carefully thought out. It was considered "interesting but not scholarly" by one of the reviewers and down-right offensive by the second. To tell the truth, however, the paper was not formally rejected. The editor Sue Treagus strongly encouraged Panozzo to revise the paper, ... and 30 years later, I will follow her advise and offer a revised paper as a tribute to John Ramsay. To quote from the original manuscript: "We should be a little more impressed that strain works so well, and less

  19. Effect of fluctuations on time-averaged multi-line NO-LIF thermometry measurements of the gas-phase temperature

    Science.gov (United States)

    Feroughi, Omid M.; Kronemayer, Helmut; Dreier, Thomas; Schulz, Christof

    2015-09-01

    Multi-line NO laser-induced fluorescence (LIF) thermometry enables accurate gas-phase temperature imaging in combustion systems through least-squares fitting of excitation spectra. The required excitation wavelength scan takes several minutes which systematic biases the results in case of temperature fluctuations. In this work, the effect of various types (linear, Gaussian and bimodal) and amplitudes of temperature fluctuations is quantified based on simulated NO-LIF excitation spectra. Temperature fluctuations of less than ±5 % result in a negligible error of less than ±1 % in temperature for all cases. Bimodal temperature distributions have the largest effect on the determined temperature. Symmetric temperature fluctuations around 900 K have a negligible effect. At lower mean temperatures, fluctuations cause a positive bias leading to over-predicted mean temperatures, while at higher temperatures the bias is negative. The results of the theoretical analysis were applied as a guide for interpreting experimental multi-line NO-LIF temperature measurements in a mildly turbulent pilot-plant scale flame reactor dedicated for nanoparticle synthesis.

    Full Text Available Every science is searching for 'it's facts', it's concept and categorical decree, and by this defines specific subject of it's science researching. Here, the researching is steered on identification of ontological contents of 'normative fact' in the aim of comprehension of it's categorical entity and conceptual disposition.'The normative fact' refers to importance, significance and sense which norm has, in other words, which is attributed to the norm by man and society, and which in the air of importance influence on it's behavior. Exclusive term of sociological science is 'normative fact' as behavior of an individual, groups, institutions and society with regard to establishment, application and changes of social norms.

    2011-07-01

    The First G-APD Cherenkov Telescope (FACT) project develops a novel camera type for very high energy gamma-ray astronomy. A total of 1440 Geiger-mode avalanche photodiodes (G-APD) are used for light detection, each accompanied by a solid light concentrator. All electronics for analog signal processing, digitization and triggering are fully integrated into the camera body. The event data are sent via Ethernet to the counting house. In order to compensate for gain variations of the G-APDs an online feedback system analyzing calibration light pulses is employed. Once the construction and commissioning of the camera is finished it will be transported to La Palma, Canary Islands, and mounted on the refurbished HEGRA CT3 telescope structure. In this talk the architecture and status of the FACT camera is presented.

  7. Quantum mechanics: Myths and facts

    CERN Document Server

    Nikolic, H

    2006-01-01

    A common understanding of quantum mechanics (QM) among students and practical users is often plagued by a number of "myths", that is, widely accepted claims on which there is not really a general consensus among experts in foundations of QM. These myths include wave-particle duality, time-energy uncertainty relation, fundamental randomness, the absence of measurement-independent reality, locality of QM, nonlocality of QM, the existence of well-defined relativistic QM, the claims that quantum field theory (QFT) solves the problems of relativistic QM or that QFT is a theory of particles, as well as myths on black-hole entropy. The fact is that the existence of various theoretical and interpretational ambiguities underlying these myths does not yet allow us to accept them as proven facts. I review the main arguments and counterarguments lying behind these myths and conclude that QM is still a not-yet-completely-understood theory open to further fundamental research.

  11. How is kinematic structure connected to the core scale from filament scale?; Mopra mapping observations with multi-lines of dense cores in Lupus I

    Science.gov (United States)

    Kiyokane, Kazuhiro; Saito, Masao; Tachihara, Kengo; Saigo, Kazuya; van Kempen, Tim; Cortes, Paulo; Hill, Tracey; Knee, Lewis; Kurono, Yasutaka; Takahashi, Satoko; Aya, Higuchi; Nyman, Lars-Ake

    2014-06-01

    Recently, high sensitivity mappings of nearby molecular clouds in far-infrared and submillimeter wavelengths with Hershel and AzTEC/ASTE show ubiquitous existence of the filamentary structures with 0.1-pc uniform width. It is important to investigate dense core formation from large scale structure via fragmentation. We have conducted MOPRA multi-line mapping observations covered on 0.02 - 0.2 pc scales of 8 dense cores in a filamentary cloud of nearby Lupus I at 140 pc. A class 0/I protostellar core IRAS 15398-3359 is included as a sample, which has an adjacent prestellar core with the separation of 0.13pc in the west. The maps of N2H+, HNC, HC3N show well associated with each core. The velocity field of C18O shows 1.4 km/s/pc from north to south over the region containing two dense cores, which is consistent with past observation of NANTEN. In contrast to C18O results, the velocity field of HC3N shows different structures, which suggest counter rotation of two dense cores; 1.2 km/s/pc from north-west to south-east around a protostellar core and 0.8 km/s/pc from east to west around a presteller core. The filament will be fragmentized and collapsed to dense cores when the line density is over 2Cs/G (where Cs is sound speed and G is gravitational constant). If that velocity gradient was caused by such situation, it should be red-blue-red-blue across two dense cores but the observed kinematics is not consistent with this scenario, which requires that the filament structure would be extremely curved with a skew angle. Although we cannot reject the collapsing interruption, those results suggest the spin-up rotating picture separated from large-scale structure.

  12. FACT, Mega-ROSA, SOLAROSA

    Science.gov (United States)

    Spence, Brian; White, Steve; Schmid, Kevin; Douglas Mark

    2012-01-01

    The Flexible Array Concentrator Technology (FACT) is a lightweight, high-performance reflective concentrator blanket assembly that can be used on flexible solar array blankets. The FACT concentrator replaces every other row of solar cells on a solar array blanket, significantly reducing the cost of the array. The modular design is highly scalable for the array system designer, and exhibits compact stowage, good off-pointing acceptance, and mass/cost savings. The assembly s relatively low concentration ratio, accompanied by a large radiative area, provides for a low cell operating temperature, and eliminates many of the thermal problems inherent in high-concentration-ratio designs. Unlike other reflector technologies, the FACT concentrator modules function on both z-fold and rolled flexible solar array blankets, as well as rigid array systems. Mega-ROSA (Mega Roll-Out Solar Array) is a new, highly modularized and extremely scalable version of ROSA that provides immense power level range capability from 100 kW to several MW in size. Mega-ROSA will enable extremely high-power spacecraft and SEP-powered missions, including space-tug and largescale planetary science and lunar/asteroid exploration missions. Mega-ROSA's inherent broad power scalability is achieved while retaining ROSA s solar array performance metrics and missionenabling features for lightweight, compact stowage volume and affordability. This innovation will enable future ultra-high-power missions through lowcost (25 to 50% cost savings, depending on PV and blanket technology), lightweight, high specific power (greater than 200 to 400 Watts per kilogram BOL (beginning-of-life) at the wing level depending on PV and blanket technology), compact stowage volume (greater than 50 kilowatts per cubic meter for very large arrays), high reliability, platform simplicity (low failure modes), high deployed strength/stiffness when scaled to huge sizes, and high-voltage operation capability. Mega-ROSA is adaptable to

  14. Concentrating Solar Power Fact Sheet

    Energy Technology Data Exchange (ETDEWEB)

    None

    2015-12-01

    This fact sheet is an overview of the Concentrating Solar Power (CSP) subprogram at the U.S. Department of Energy SunShot Initiative. CSP is a dispatchable, renewable energy option that uses mirrors to focus and concentrate sunlight onto a receiver, from which a heat transfer fluid carries the intense thermal energy to a power block to generate electricity. CSP systems can store solar energy to be used when the sun is not shining. It will help meet the nation’s goal of making solar energy fully cost-competitive with other energy sources by the end of the decade. Worldwide, CSP activity is rapidly scaling, with approximately 10 gigawatts (GW) in various stages of operation or development. In the United States alone, nearly 2 GW of CSP are in operation.

  20. Facts and fictions about polymorphism.

    Science.gov (United States)

    Cruz-Cabeza, Aurora J; Reutzel-Edens, Susan M; Bernstein, Joel

    2015-12-01

    We present new facts about polymorphism based on (i) crystallographic data from the Cambridge Structural Database (CSD, a database built over 50 years of community effort), (ii) 229 solid form screens conducted at Hoffmann-La Roche and Eli Lilly and Company over the course of 8+ and 15+ years respectively and (iii) a dataset of 446 polymorphic crystals with energies and properties computed with modern DFT-d methods. We found that molecular flexibility or size has no correlation with the ability of a compound to be polymorphic. Chiral molecules, however, were found to be less prone to polymorphism than their achiral counterparts and compounds able to hydrogen bond exhibit only a slightly higher propensity to polymorphism than those which do not. Whilst the energy difference between polymorphs is usually less than 1 kcal mol(-1), conformational polymorphs are capable of differing by larger values (up to 2.5 kcal mol(-1) in our dataset). As overall statistics, we found that one in three compounds in the CSD are polymorphic whilst at least one in two compounds from the Roche and Lilly set display polymorphism with a higher estimate of up to three in four when compounds are screened intensively. Whilst the statistics provide some guidance of expectations, each compound constitutes a new challenge and prediction and realization of targeted polymorphism still remains a holy grail of materials sciences.

  7. Fact sheet: Ethanol from corn

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1999-05-31

    This fact sheet is intended to provide an overview of the advantages of ethanol from corn, emphasizing ethanol`s contribution to environmental protection and sustainable agriculture. Ethanol, an alternative fuel used as an octane enhancer is produced through the conversion of starch to sugars by enzymes, and fermentation of these sugars to ethanol by yeast. The production process may involve wet milling or dry milling. Both these processes produce valuable by-products, in addition to ethanol and carbon dioxide. Ethanol contains about 32,000 BTU per litre. It is commonly believed that using state-of-the-art corn farming and corn processing processes, the amount of energy contained in ethanol and its by-products would be more than twice the energy required to grow and process corn into ethanol. Ethanol represents the third largest market for Ontario corn, after direct use as animal feed and wet milling for starch, corn sweetener and corn oil. The environmental consequences of using ethanol are very significant. It is estimated that a 10 per cent ethanol blend in gasoline would result in a 25 to 30 per cent decrease in carbon monoxide emissions, a 6 to 10 per cent decrease in net carbon dioxide, a slight increase in nitrous oxide emissions which, however, would still result in an overall decrease in ozone formation, since the significant reduction in carbon monoxide emissions would compensate for any slight increase in nitrous oxide. Volatile organic compounds emission would also decrease by about 7 per cent with a 10 per cent ethanol blend. High level blends could reduce VOCs production by as much as 30 per cent. 7 refs.

  8. Legal Facts and Dependence on Representations

    Directory of Open Access Journals (Sweden)

    Almäng Jan

    2016-03-01

    Full Text Available Barry Smith has recently argued against John Searle’s thesis that institutional facts exist because they are represented as existing in a certain community. Smith argues that institutional facts can exist even though they are not represented as existing and that institutional facts can fail to obtain even though they are represented as obtaining. In this paper it is argued that Smith’s challenge can be met for a certain class of legal facts. I argue that in order to solve the problem posed by Smith, we must distinguish between three different kinds of institutional facts and between three different kinds of representation which sustain their existence.

    FACT is heterodimer protein complex and histone chaperone that plays an important role in maintaining and modifying chromatin structure during various DNA-dependent processes. FACT is involved in nucleosome assembly de novo and in the preservation and recovery of the nucleosome structure during and after transcription, replication and repair of DNA. During transcript elongation FACT reduces the height of the nucleosome barrier and supports survival of the nucleosomes during and after passage of RNA polymerase II. In this process FACT interacts with histone H2A-H2B dimer in nucleosomes, thus facilitating uncoiling of nucleosomal DNA from the octamer of histones; it also facilitates subsequent recovery of the canonical structure of the nucleosome after transcription. FACT also plays an important role in transformation of human cells and in maintaining the viability of the tumor cells.

  5. FACTS device control strategy using PMU

    Directory of Open Access Journals (Sweden)

    Mohd Tauseef Khan

    2016-09-01

    Full Text Available The laying and commissioning of new transmission line is very difficult due to socio-economic problems, like environmental clearances, right of way, etc. Therefore, there is an emphasis on better utilization of available transmission infrastructure. FACTS devices can provide reactive power compensation, transmission capability enhancement, and voltage and stability improvement. FACTS devices operate under the command of system operator who analyses its demand by the data acquired through traditional SCADA system, state estimation algorithms and PMUs. SCADA together with PMU give accurate information about the operational state of power system. This paper proposes a scheme to automate the FACTS devices in collaboration with PMUs in a more efficient way. Highly precised data from PMUs can be fed to intelligent controllers for effective analyzing and automating the FACTS device through control command. Thus, this combination can provide real time control of reactive power, together with enhancement of power handling capability and stability improvement.

    Traditional fact checking by expert journalists cannot keep up with the enormous volume of information that is now generated online. Computational fact checking may significantly enhance our ability to evaluate the veracity of dubious information. Here we show that the complexities of human fact checking can be approximated quite well by finding the shortest path between concept nodes under properly defined semantic proximity metrics on knowledge graphs. Framed as a network problem this approach is feasible with efficient computational techniques. We evaluate this approach by examining tens of thousands of claims related to history, entertainment, geography, and biographical information using a public knowledge graph extracted from Wikipedia. Statements independently known to be true consistently receive higher support via our method than do false ones. These findings represent a significant step toward scalable computational fact-checking methods that may one day mitigate the spread of harmful misinformation...

    Directory of Open Access Journals (Sweden)

    Ana M. Cubillas

    2009-01-01

    Full Text Available Hollow-core photonic bandgap fibres (HC-PBFs have emerged as a novel technology in the field of gas sensing. The long interaction pathlengths achievable with these fibres are especially advantageous for the detection of weakly absorbing gases. In this work, we demonstrate the good performance of a HC-PBF in the detection of the ν2 + 2ν3 band of methane, at 1.3 μm. The Q-branch manifold, at 1331.55 nm, is targeted for concentration monitoring purposes. A computationally optimized multi-line model is used to fit the Q-branch. Using this model, a detection limit of 98 ppmv (parts per million by volume is estimated.

  10. Facts, Principles and the Third Man

    Directory of Open Access Journals (Sweden)

    Lea Ypi

    2012-02-01

    Full Text Available In the dialogue entitled “Parmenides” Plato introduces an objection to his own theory of ideas, one that he never managed to answer, dubbed by Aristotle as the “Third Man” argument. According to that objection, the theory of ideas is threatened with infinite regress when examining why a specific Platonic form (say, justice is predicated of a particular set of facts. This article seeks to show how any defence of fact-insensitive principles like the one offered by G.A. Cohen in his recent book “Rescuing Justice and Equality” is vulnerable to a similar objection. Cohen wants to insist that, when showing why facts support principles, the process of reason-giving is finite and terminates in fact-independent comprehensive principles. But something like the Third Man argument undermines Cohen’s conclusion just as it does Plato’s. The search for ultimate fact-independent principles is indeed threatened by infinite regress.

    The First G-APD Cherenkov Telescope is the first Imaging Air Cherenkov Telescope which uses silicon photon detectors (G-APDs aka SiPM) as photo sensors. With more than four years of operation, FACT proved an application of SiPMs is suitable for the field of ground-based gamma-ray astronomy. Due to the stable flux at TeV energies, the Crab Nebula is handled as a ''standard candle'' in Cherenkov astronomy. The analysis of its energy spectrum and comparison with other experiments, allows to evaluate the performance of FACT. A modern analysis chain, based on data stream handling and multivariate analysis methods was developed in close cooperation with the department of computer science at the TU Dortmund. In this talk, this analysis chain and its application are presented. Further to this, results, including the energy spectrum of the Crab Nebula, measured with FACT, are shown.

  12. FVQA: Fact-based Visual Question Answering.

    Science.gov (United States)

    Wang, Peng; Wu, Qi; Shen, Chunhua; Dick, Anthony; Hengel, Anton van den

    2017-09-19

    Visual Question Answering (VQA) has attracted much attention in both computer vision and natural language processing communities, not least because it offers insight into the relationships between two important sources of information. Current datasets, and the models built upon them, have focused on questions which are answerable by direct analysis of the question and image alone. The set of such questions that require no external information to answer is interesting, but very limited. It excludes questions which require common sense, or basic factual knowledge to answer, for example. Here we introduce FVQA (Fact-based VQA), a VQA dataset which requires, and supports, much deeper reasoning. FVQA primarily contains questions that require external information to answer. We thus extend a conventional visual question answering dataset, which contains image-question-answer triplets, through additional image-question-answer-supporting fact tuples. Each supporting-fact is represented as a structural triplet, such as .

  13. Reinforcing Power Grid Transmission with FACTS Devices

    CERN Document Server

    Frolov, Vladimir; Chertkov, Misha

    2013-01-01

    We explore optimization methods for planning the placement, sizing and operations of Flexible Alternating Current Transmission System (FACTS) devices installed into the grid to relieve congestion created by load growth or fluctuations of intermittent renewable generation. We limit our selection of FACTS devices to those that can be represented by modification of the inductance of the transmission lines. Our master optimization problem minimizes the $l_1$ norm of the FACTS-associated inductance correction subject to constraints enforcing that no line of the system exceeds its thermal limit. We develop off-line heuristics that reduce this non-convex optimization to a succession of Linear Programs (LP) where at each step the constraints are linearized analytically around the current operating point. The algorithm is accelerated further with a version of the cutting plane method greatly reducing the number of active constraints during the optimization, while checking feasibility of the non-active constraints post...

  14. Power System Stability Enhancement Using Fact Devices

    Directory of Open Access Journals (Sweden)

    Mr. B. T. Ramakrishna Rao

    2014-04-01

    Full Text Available The development of the modern power system has led to an increasing complexity in the study of power systems, and also presents new challenges to power system stability, and in particular, to the aspects of transient stability and small-signal stability. So Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS technology comes into effect with relatively low investment, compared to new transmission or generation facilities. Flexible AC transmission system (FACTS devices use power electronics components to maintain controllability and capability of electrical power system. The paper aims towards the performance of UPFC is compared with other FACTS devices such as Static Synchronous Series Compensator (SSSC, Thyristor Controlled Series Capacitor (TCSC, and Static Var Compensator (SVC respectively. The simulation results demonstrate the effectiveness of the UPFC on transient stability of the system.

  15. Facts and Methods need to be taught

    Science.gov (United States)

    Zimmerman, George

    2015-03-01

    Current trends in the K-12 educational establishment tend to concentrate on ``understanding'', both the ``understanding `` of how the student thinks and the student's ``understanding'' of a concept. In many cases the teaching of facts upon which the student might base his/her ``understanding'' is neglected. The lack of facts is amplified in our digital age where the exposure to reality is replaced by a virtual experience. This is one of the reasons for the limitations our college students exhibit. Examples in physics and math will be discussed, as well as possible remedies.

    Full Text Available Because their capability to change the network parameters with a rapid response and enhanced flexibility, flexible AC transmission system (FACTS devices have taken more attention in power systems operations as improvement of voltage profile and minimizing system losses. In this way, this paper presents a multi-objective evolutionary algorithm (MOEA to solve optimal reactive power dispatch (ORPD problem with FACTS devices. This nonlinear multi-objective problem (MOP consists to minimize simultaneously real power loss in transmission lines and voltage deviation at load buses, by tuning parameters and searching the location of FACTS devices. The constraints of this MOP are divided to equality constraints represented by load flow equations and inequality constraints such as, generation reactive power sources and security limits at load buses. Two types of FACTS devices, static synchronous series compensator (SSSC and unified power flow controller (UPFC are considered. A comparative study regarding the effects of an SSSC and an UPFC on voltage deviation and total transmission real losses is carried out. The design problem is tested on a 6-bus system.

    In ground-based gamma-ray astronomy, muon ring images are an important event class for instrument calibration and monitoring of its properties. In this talk, a multivariate approach will be presented, that is well suited for real time extraction of muons from data streams of Imaging Atmospheric Cherenkov Telescopes (IACT). FACT, the First G-APD Cherenkov Telescope is located on the Canary Island of La Palma and is the first IACT to use Silicon Photomultipliers for detecting the Cherenkov photons of extensive air showers. In case of FACT, the extracted muon events are used to calculate the time resolution of the camera. In addition, the effect of the mirror alignment in May 2014 on properties of detected muons is investigated. Muon candidates are identified with a random forest classification algorithm. The performance of the classifier is evaluated for different sets of image parameters in order to compare the gain in performance with the computational costs of their calculation.

  16. [Epididymitis in Children: Fact or Fiction].

    Science.gov (United States)

    Beetz, Rolf; Stehr, Maximilian

    2017-09-01

    Epididymitis is one of the most frequent causes of acute scrotum during childhood. Unlike in adults, ascending bacterial infections are rarely the underlying cause of the condition in children. Antibacterial treatment in accordance with a prior antibiogram is possible in the presence of leukocyturia and significant bacteriuria. For the remaining cases, there are no definite criteria allowing for a decision on acute antibacterial treatment. The fact that antibacterial treatment is still initiated in cases of epididymitis in the clinical routine setting is based on the assumption of a possible infection rather than being based on facts. This dilemma will probably not be entirely resolved until adequate diagnostic markers for the different trigger mechanisms of epididymitis have been found. © Georg Thieme Verlag KG Stuttgart · New York.

  17. Perceived social presence reduces fact-checking.

    Science.gov (United States)

    Jun, Youjung; Meng, Rachel; Johar, Gita Venkataramani

    2017-06-06

    Today's media landscape affords people access to richer information than ever before, with many individuals opting to consume content through social channels rather than traditional news sources. Although people frequent social platforms for a variety of reasons, we understand little about the consequences of encountering new information in these contexts, particularly with respect to how content is scrutinized. This research tests how perceiving the presence of others (as on social media platforms) affects the way that individuals evaluate information-in particular, the extent to which they verify ambiguous claims. Eight experiments using incentivized real effort tasks found that people are less likely to fact-check statements when they feel that they are evaluating them in the presence of others compared with when they are evaluating them alone. Inducing vigilance immediately before evaluation increased fact-checking under social settings.

  18. Astronomy. Science or culture? Fact and fiction

    Science.gov (United States)

    Belmonte Avilés, J. A.

    Astronomy is often said to be one of the oldest sciences of humanity. But this statement disregards the fact that the word “science”, as it is understood today, can hardly be used to describe the astronomical practices of, for example, the builders of megaliths or the ancient Egyptians. This type of astronomy, however, was always “culture” as it was closely linked to both religious and profane practices that led to better use of resources and greater understanding of the cosmos. Cultural astronomy, in its two branches of archaeoastronomy and ethnoastronomy, studies these practices. Since these are disciplines that lie somewhere between social sciences, especially archaeology and anthropology from which they obtain their epistemology, and classic astronomy, from which they obtain their mathematical tools, it is not always easy to carry out research in them. It is therefore often essential to start out by distinguishing between fact and fiction.

    Global warming, which is mainly caused by energy consumption, is becoming a major problem. In order to reduce energy consumption of office buildings even further, new control technology is needed. A very exciting development occurs in the field of control strategy, which integrates the end-user behaviour. In the frame of the SMART (Smart Multi Agent internet Technology) and IIGO (Intelligent Internet mediated control in the built environment) project, an external real time information system was integrated into a Building Management System in order to improve energy and comfort control. In the EBOB, Energy Efficient Behaviour of Office Buildings, a European EU-FP5 program project a different type of technology, Forgiving Technology, was developed. This paper presents insights into SMART, IIGO and EBOB and the resulting combined technology; FACT, Forgiving Agent Comfort Technology. The TU/e developed this FACT technology into a concept for Careful Buildings. (orig.)

    2012-03-01

    Full Text Available Quot homines tot sententiae seems a good summary of the variety of critical readings of lyric poetry in general and of Horace’s position on Augustus in particular. This raises the interesting question of the position of factual information in poetry: does lyric as genre imply a choice for fiction as opposed to fact or can some references to contemporary personalities or incidents be taken as realistic? In this case specifically: can what Horace says about Augustus be taken as a realistic assessment of the emperor? To complicate matters, Augustus was a powerful personage who wanted and often managed to put his own stamp on things1 — in himself an embodiment of the opposition between fact and fiction. Given this undoubtedly heady mix, the paper will try to make some

  8. Motor skill depends on knowledge of facts.

    Science.gov (United States)

    Stanley, Jason; Krakauer, John W

    2013-01-01

    Those in 20th century philosophy, psychology, and neuroscience who have discussed the nature of skilled action have, for the most part, accepted the view that being skilled at an activity is independent of knowing facts about that activity, i.e., that skill is independent of knowledge of facts. In this paper we question this view of motor skill. We begin by situating the notion of skill in historical and philosophical context. We use the discussion to explain and motivate the view that motor skill depends upon knowledge of facts. This conclusion seemingly contradicts well-known results in cognitive science. It is natural, on the face of it, to take the case of H.M., the seminal case in cognitive neuroscience that led to the discovery of different memory systems, as providing powerful evidence for the independence of knowledge and skill acquisition. After all, H.M. seems to show that motor learning is retained even when previous knowledge about the activity has been lost. Improvements in skill generally require increased precision of selected actions, which we call motor acuity. Motor acuity may indeed not require propositional knowledge and has direct parallels with perceptual acuity. We argue, however, that reflection on the specifics of H.M.'s case, as well as other research on the nature of skill, indicates that learning to become skilled at a motor task, for example tennis, depends also on knowledge-based selection of the right actions. Thus skilled activity requires both acuity and knowledge, with both increasing with practice. The moral of our discussion ranges beyond debates about motor skill; we argue that it undermines any attempt to draw a distinction between practical and theoretical activities. While we will reject the independence of skill and knowledge, our discussion leaves open several different possible relations between knowledge and skill. Deciding between them is a task to be resolved by future research.

    2012-01-01

    Quot homines tot sententiae seems a good summary of the variety of critical readings of lyric poetry in general and of Horace’s position on Augustus in particular. This raises the interesting question of the position of factual information in poetry: does lyric as genre imply a choice for fiction as opposed to fact or can some references to contemporary personalities or incidents be taken as realistic? In this case specifically: can what Horace says about Augustus be taken as a realistic asse...

    1994-12-31

    Modern power electronic devices such as thyristors and GTOs have made it possible to design controllable network elements, which will play a considerable role in ensuring reliable economic operation of transmission systems as a result of their capability to rapidly change active and reactive power. A number of FACTS elements for high-speed active and reactive power control will be described. Control of power system fluctuations in meshed systems by modulation of active and reactive power will be demonstrated using a number of examples. (author) 7 refs., 11 figs.

The SunShot fact sheet outlines goals and successes of the program as it works with private companies, universities, non-profit organizations, state and local governments, and national laboratories to drive down the cost of solar electricity to $0.06 per kilowatt-hour, without incentives, by the year 2020.

  16. Stylized facts and multiple realizability in econophysics

    Directory of Open Access Journals (Sweden)

    Christophe Schinckus

    2014-01-01

    Full Text Available Stylized facts are persistent macro-regularities which cannot be described in terms of microeconomic theory. Through the argument of multiple realizability, this methodological paper claims that a top down agent-based econophysics can contribute to a better understanding of complex economic systems in two ways: on the one hand, it clarifies the gap between micro and macro scales by proving an algorithmic derivability of the latter; and on the other hand, this modelling provides microfoundations (and then potentially an economic meaning to macro-patterns usually identified in the observation of these complex systems.

  17. Aging of cell membranes: facts and theories.

    Science.gov (United States)

    Zs-Nagy, Imre

    2014-01-01

    This chapter is intended to outline the main results of a research trend realized by the author during the last 45 years, focused on the main role played by the cell membrane in the aging process. It is a very wide field; therefore, the reader cannot expect in this limited space a detailed description, but will be given a wide, interdisciplinary insight into the main facts and theories regarding cellular aging. The central idea described here is the concept called the membrane hypothesis of aging (MHA). The history, the chemical roots, physicochemical facts, biophysical processes, as well as the obligatory biochemical consequences are all touched in by indicating the most important sources of detailed knowledge for those who are more interested in the basic biology of the aging process. This chapter covers also the available anti-aging interventions on the cell membrane by means of the centrophenoxine treatment based on the MHA. It also briefly interprets the possibilities of a just developing anti-aging method by using the recombinant human growth hormone, essential basis of which is the species specificity, and the general presence of receptors of this hormone in the plasma membrane of all types of cells.

  18. Comparison of Ontology Reasoners: Racer, Pellet, Fact++

    Science.gov (United States)

    Huang, T.; Li, W.; Yang, C.

    2008-12-01

    In this paper, we examine some key aspects of three of the most popular and effective Semantic reasoning engines that have been developed: Pellet, RACER, and Fact++. While these reasonably advanced reasoners share some notable similarities, it is ultimately the creativity and unique nature of these reasoning engines that have resulted in the successes of each of these reasoners. Of the numerous dissimilarities, the most obvious example might be that while Pellet is written in Java, RACER employs the Lisp programming language and Fact++ was developed using C++. From this and many other distinctions in the system architecture, we can understand the benefits of each reasoner and potentially discover certain properties that may contribute to development of an optimal reasoner in the future. The objective of this paper is to establish a solid comparison of the reasoning engines based on their system architectures, features, and overall performances in real world application. In the end, we expect to produce a valid conclusion about the advantages and problems in each reasoner. While there may not be a decisive first place among the three reasoners, the evaluation will also provide some answers as to which of these current reasoning tools will be most effective in common, practical situations.

  19. Single-Phase Single-Stage PV-Grid System Using VSI Based on Simple Control Circuit

    Directory of Open Access Journals (Sweden)

    Slamet Riyadi

    2012-12-01

    Full Text Available Integrating electric energy generated by PV with utilities has been developed. Some of these using two-stage converters and the others using single stage converters. For systems with two-stage converters, the first stage converter acts as a MPPT to maximize power generated by PV and the second stage is used as an interface to the utilities. In the single-stage system, an inverter is used for both function. In this paper, PV-Grid System using a single-stage Voltage Source Inverter is proposed. The simple control circuit to make PV generate maximum power and keeping power equilibrium between PV and inverter output power is used. To verify the analysis, simulations are done.

    Full Text Available There is an ongoing debate over the extent to which language development shares common processing mechanisms with other domains of learning. It is well-established that toddlers will systematically extend object labels to similarly-shaped category exemplars (e.g., Landau, Smith, & Jones, 1988; Markman & Hutchinson, 1984. However, previous research is inconclusive as to whether young children will similarly extend factual information about an object to other category members. We explicitly contrast facts varying in category relevance, and test for extension using two different tasks. Three- to four-year-olds (N = 61 were provided with one of three types of information about a single novel object: a category-relevant fact (‘it’s from a place called Modi’, a category-irrelevant fact (‘my uncle gave it to me’, or an object label (‘it’s called a Modi’. At test, children provided with the object name or category-relevant fact were significantly more likely to display systematic category extension than children who learnt the category-irrelevant fact. Our findings contribute to a growing body of evidence that the mechanisms responsible for word learning may be domain-general in nature.

  3. Fact and fictions in FX arbitrage processes

    Science.gov (United States)

    Cross, Rod; Kozyakin, Victor

    2015-02-01

    The efficient markets hypothesis implies that arbitrage opportunities in markets such as those for foreign exchange (FX) would be, at most, short-lived. The present paper surveys the fragmented nature of FX markets, revealing that information in these markets is also likely to be fragmented. The "quant" workforce in the hedge fund featured in The Fear Index novel by Robert Harris would have little or no reason for their existence in an EMH world. The four currency combinatorial analysis of arbitrage sequences contained in [1] is then considered. Their results suggest that arbitrage processes, rather than being self-extinguishing, tend to be periodic in nature. This helps explain the fact that arbitrage dealing tends to be endemic in FX markets.

  4. Neutrino masses From fantasy to facts

    CERN Document Server

    Valle, José W F

    1999-01-01

    Theory suggests the existence of neutrino masses, but little more. Facts are coming close to reveal our fantasy: solar and atmospheric neutrino data strongly indicate the need for neutrino conversions, while LSND provides an intriguing hint. The simplest ways to reconcile these data in terms of neutrino oscillations invoke a light sterile neutrino in addition to the three active ones. Out of the four neutrinos, two are maximally-mixed and lie at the LSND scale, while the others are at the solar mass scale. These schemes can be distinguished at neutral-current-sensitive solar & atmospheric neutrino experiments. I discuss the simplest theoretical scenarios, where the lightness of the sterile neutrino, the nearly maximal atmospheric neutrino mixing, and the generation of $\\Delta {m^2}_\\odot$ & $\\Delta {m^2}_{atm}$ all follow naturally from the assumed lepton-number symmetry and its breaking. Although the most likely interpretation of the present data is in terms of neutrino-mass-induced oscillations, one...

    The First G-APD Cherenkov Telescope (FACT) was built on the Canary Island of La Palma in October 2011 as a proof of principle for silicon based photosensors in Cherenkov Astronomy. The scientific goal of the project is to study the variability of active galatic nuclei (AGN) at TeV energies. Observing a small sample of TeV blazars whenever possible, an unbiased data sample is collected. This allows to study the variability of the selected objects on timescales from hours to years. Results from the first three years of monitoring will be presented. To provide quick flare alerts to the community and trigger multi-wavelength observations, a quick look analysis has been installed on-site providing results publicly online within the same night. In summer 2014, several flare alerts were issued. Results of the quick look analysis are summarized.

    The maximization of the photon detection efficiency (PDE) is a key issue in the development of cameras for Imaging Atmospheric Cherenkov Telescopes. Geiger-mode Avalanche Photodiodes (G-APD) are a promising candidate to replace the commonly used photomultiplier tubes by offering a larger PDE and in addition a facilitated handling. The FACT (First G-APD Cherenkov Telescope) project evaluates the feasibility of this change by building a camera based on 1440 G-APDs for an existing small telescope. As a first step towards a full camera, a prototype module using 144 G-APDs was successfully built and tested. The strong temperature dependence of G-APDs is compensated using a feedback system, which allows to keep the gain of the G-APDs constant to 0.5%.

    2017-01-01

    In this chapter we allude to a series of facts and fallacies often encountered in the description of tumor hypoxia, a relevant trait of the tumor microenvironment and a paramount driver of tumor aggressiveness and treatment resistance. The critical role of diffusion distances, terminological inconsistencies considering O2 partial pressures vs. O2 concentrations and with it the use of inept units, the impact of O2 depletion on proliferation and cell viability, the switch in the Warburg dogma , the distribution of hypoxic subvolumes within a tumor, the involvement of O2 diffusion shunts in the development of chronic hypoxia, and the role of endogenous biomarkers as surrogates for the assessment of hypoxia are discussed in more detail. Special emphasis is put on the clinical relevance of these misconceptions and misinterpretations and their impact on the assessment of hypoxia as well as hypoxia-targeted treatment planning.

    Should scientific facts and methods have an epistemically privileged status in public reason? In Rawls’s public reason account he asserts what we will label the Scientific Standard Stricture: citizens engaged in public reason must be guided by non-controversial scientific methods, and public reason...... must be in line with non-controversial scientific conclusions. The Scientific Standard Stricture is meant to fulfill important tasks such as enabling the determinateness and publicity of the public reason framework. However, Rawls leaves us without elucidation with regard to when science...... is and is not ‘non-controversial’ and more importantly, we are left without a justification for a stricture which excludes certain controversial beliefs and methods of inquiry from the realm of political justification. In this article, we offer what we deem to be the most plausible interpretation of Rawls...

  3. Transgene flow: Facts, speculations and possible countermeasures

    Science.gov (United States)

    Ryffel, Gerhart U

    2014-01-01

    Convincing evidence has accumulated that unintended transgene escape occurs in oilseed rape, maize, cotton and creeping bentgrass. The escaped transgenes are found in variant cultivars, in wild type plants as well as in hybrids of sexually compatible species. The fact that in some cases stacked events are present that have not been planted commercially, implies unintended recombination of transgenic traits. As the consequences of this continuous transgene escape for the ecosystem cannot be reliably predicted, I propose to use more sophisticated approaches of gene technology in future. If possible GM plants should be constructed using either site-directed mutagenesis or cisgenic strategies to avoid the problem of transgene escape. In cases where a transgenic trait is needed, efficient containment should be the standard approach. Various strategies available or in development are discussed. Such a cautious approach in developing novel types of GM crops will enhance the sustainable potential of GM crops and thus increase the public trust in green gene technology. PMID:25523171

  4. FACT — STATUS AND FIRST RESULTS

    Directory of Open Access Journals (Sweden)

    Daniela Dorner

    2014-06-01

    Full Text Available FACT is the first imaging Cherenkov telescope based on a camera using solid state photosensors (Geigermode Avalanche Photodiodes G-APD aka SiPM. Since October 2011, it has been taking data regularly. Apart from commissioning and calibration measurements, it has already started regular operation, where the main goal is to do long-term monitoring of bright TeV blazars. In June 2012, a flare of Mrk 501 was observed. Thanks to the robustness of the G-APDs, observations can be carried out during strong moon light without aging of the sensors. This improves the duty cycle of the instrument and provides better statistics for long-term light curves. The telescope, situated on the Canary Island of La Palma, is operated, already now, remotely from central Europe. For the future, robotic operation is planned. We report on our experiences during the commissioning, and we present first results from the first 1.5 years of observations.

  5. Stylized facts of intraday precious metals.

    Science.gov (United States)

    Batten, Jonathan; Lucey, Brian; McGroarty, Frank; Peat, Maurice; Urquhart, Andrew

    2017-01-01

    This paper examines the stylized facts, correlation and interaction between volatility and returns at the 5-minute frequency for gold, silver, platinum and palladium from May 2000 to April 2015. We study the full sample period, as well as three subsamples to determine how high-frequency data of precious metals have developed over time. We find that over the full sample, the number of trades has increased substantially over time for each precious metal, while the bid-ask spread has narrowed over time, indicating an increase in liquidity and price efficiency. We also find strong evidence of periodicity in returns, volatility, volume and bid-ask spread. Returns and volume both experience strong intraday periodicity linked to the opening and closing of major markets around the world while the bid-ask spread is at its lowest when European markets are open. We also show a bilateral Granger causality between returns and volatility of each precious metal, which holds for the vast majority subsamples.

  6. Systematic reviews: Separating fact from fiction.

    Haddaway, Neal R; Bilotta, Gary S

    2016-01-01

    The volume of scientific literature continues to expand and decision-makers are faced with increasingly unmanageable volumes of evidence to assess. Systematic reviews (SRs) are powerful tools that aim to provide comprehensive, transparent, reproducible and updateable summaries of evidence. SR methods were developed, and have been employed, in healthcare for more than two decades, and they are now widely used across a broad range of topics, including environmental management and social interventions in crime and justice, education, international development, and social welfare. Despite these successes and the increasing acceptance of SR methods as a 'gold standard' in evidence-informed policy and practice, misconceptions still remain regarding their applicability. The aim of this article is to separate fact from fiction, addressing twelve common misconceptions that can influence the decision as to whether a SR is the most appropriate method for evidence synthesis for a given topic. Through examples, we illustrate the flexibility of SR methods and demonstrate their suitability for addressing issues on environmental health and chemical risk assessment.

  7. Electromagnetic shielding mats: facts and fiction.

    Leitgeb, N; Cech, R

    2007-01-01

    The use of electricity is accompanied by electric and magnetic fields which, intended or not, became a part of our environment. However, fear from environmental electromagnetic fields (EMFs) is widespread and so is business with fear. A number of more or less serious products including miracle products are placed on the market partly at excessive costs. By numerical simulation the efficiency of electromagnetic shielding mats was investigated and claims of manufacturers and their cited expert opinions checked. It could be shown that such products do not fulfil the justified expectations of customers, neither in the extremely low frequency (ELF) nor in the radiofrequency (RF) range. On the contrary, these mats usually make things even worse. The connection to ground, if available, might increase the belief on shielding efficiency, but in fact it even enhances fields instead of improving shielding. The electric conductivity of the mat material plays a minor role in the ELF range and enhances field increase in the RF range. It can not explain the enormous price differences. It could be shown that positive reports can be explained by result picking and exceptional arrangements of selected field sources. Overall, the investigation showed that manufacturer's claims about the shielding effectiveness are misleading and fool the customers about the real situation. Therefore, acquisition and use of electromagnetic shielding mats must be strongly discouraged.

  14. Observational Facts of Sustained Departure Plateau Vortexes

    Institute of Scientific and Technical Information of China (English)

    YU Shuhua; GAO Wenliang; PENG Jun; XIAO Yuhua

    2014-01-01

    By using the twice-daily atmospheric observation data from 1998 to 2012, station rainfall data, Tropical Rainfall Measure Mission (TRMM) data, as well as the plateau vortex and shear line year book, charac-teristics of the sustained departure plateau vortexes (SDPVs) are analyzed. Some new useful observational facts and understanding are obtained about the SDPV activities. The following results are obtained. (1) The active period of SDPVs is from June to August, most in July, unlike that of the unsustained depar-ture plateau vortexes (UDPVs), which have same occurrence frequencies in the three summer months. (2) The SDPVs, generated mainly in the Qumalai neighborhood and situated in a sheared surrounding, move eastward or northeastward, while the UDPVs are mainly led by the upper-level trough, and move eastward or southeastward. (3) The SDPVs influence wide areas of China, even far to the Korean Peninsula, Japan, and Vietnam. (4) The SDPVs change their intensities and properties on the way to the east. Most of them become stronger and produce downpour or sustained regional rainstorms to the south of Yellow River. (5) The longer the SDPV sustains, the more baroclinity it has. (6) When an SDPV moves into the sea, its central pressure descends and rainfall increases in all probability. (7) An SDPV might spin over the bend of the Yellow River when there exists a tropical cyclone in the East China Sea. It could also move oppositely to a landed tropical low pressure originated from the sea to the east of Taiwan or from the South China Sea.

  15. Facing the Facts and Living our Values

    Science.gov (United States)

    Snieder, R.

    2009-05-01

    One of the major challenges for the 21st Century is to establish an energy system that is safe, affordable, sustainable, and environmentally responsible. With current reserves in coal and nonconventional oil, we will not run out of energy in the coming century, but we may pay a price with a climate that heats up with an unprecedented rate of change. Even with current technology, there is a wealth of information and solutions available, and we could benefit much by using this knowledge more effectively than we do now. An example is the McKinsey report on the cost of avoiding CO2 emissions (http://mckinsey.com/clientservice/ccsi/greenhousegas.asp). According to this analysis, the USA can avoid about 40% of its CO2 emissions at zero total cost. About 20% of those emissions can be saved by taking steps that save money and reduce energy consumption. In the process of working on these steps for reducing CO2 emissions, many jobs are created. The energy and climate challenge thus comes with new opportunities. Geoscientists can make a difference by talking about energy and climate, and by helping create awareness for the energy challenge and the associated opportunities. Scientists and engineers are, in general, loath to discuss the issue of values. Yet, despite the logical basis of science, our science and the personal views of scientists can help shape our societal values. This can happen, however, only when scientists articulate their values and stimulate their students and the public to make conscious choices what their values are. Education, whether it is in the classroom, at a community center, church, or service club, can play an important role in making the public aware of the facts that are important for the choices that we need to make at a personal and societal level for our energy use. In order to facilitate this type of communication I have created a public lecture that is available online (http://www.mines.edu/˜rsnieder/Global_Energy.html). As a geoscientist

    FACT plays important roles in both gene transcription and DNA replication. However, how this protein complex is targeted to these two distinct cellular processes remains largely unknown. Here we show that ubiquitylation of the Spt16 subunit of FACT by Rtt101, the cullin subunit of an E3 ubiquitin ligase in Saccharomyces cerevisiae, links FACT to DNA replication. We find Rtt101 interacts with and ubiquitylates Spt16 in vitro and in vivo. Deletion of RTT101 leads to reduced association of both FACT and the replicative helicase MCM with replication origins. Loss of Rtt101 also reduces binding of FACT to MCM, but not the association of FACT with Leo1 and Spt5, two proteins involved in transcription. Origin function is compromised in cells lacking Rtt101 or with an Spt16 mutation. These findings identify Spt16 as an Rtt101 substrate, and suggest that Spt16 ubiquitylation is important for FACT to function during DNA replication.

    Energy Technology Data Exchange (ETDEWEB)

    Coronado Gallegos, Ixtlahuatl

    2001-09-15

    In this work techniques for the location of FACTS devices (Flexible Systems of AC Transmission) in a multi-machine power system in order to improve the electromechanical transient behavior is presented. In the first part, a brief introduction is presented about the FACTS devices, in which are mentioned some of the main characteristics, classification and advantages that their utilization represents. In the next part, the formulation of the matrix of state in the context of machine-infinite bar considering the possibility of including a power system stabilizer is developed. Later the formulation is extended to a multi-machine system. Additionally the form of including a series capacitor controlled by thyristors (TCSC) as well as a unified controller of power flows (UPFC) is analyzed. An analysis of the UPFC is carried out in conditions of stationary and dynamic state in a system machine-infinite bar in order to know its operating characteristics and its capacity for dampening power oscillations through its entrances of control when using local signals. In the last part of the work a methodology is proposed to attack the problem of the location of FACTS devices, which is based in the technique of response to the system frequency. In order to validate this proposal some cases of study are used and the results obtained with the ones provided by other techniques are compared. Also some auxiliary means are proposed for obtaining the feasible locations utilizing other mathematical tools such as the singular values and the sensitivities. Finally, simulations in the time are carried out to corroborate the results obtained.

  20. Fiction in Fact and Fact in Fiction in the Writing of Joyce Carol Oates

    Directory of Open Access Journals (Sweden)

    Tanya L. Tromble

    2015-01-01

    Full Text Available Joyce Carol Oates draws extensively on news stories, as well as on elements of her own family’s past, to find inspiration for her works of fiction. She has written about the Chappaquiddick incident involving Ted Kennedy and the JonBenet Ramsay murder case. She has worked the Niagara Falls Love Canal environmental scandal into the framework of The Falls and taken inspiration from sordid events from her own family’s past in the beginning of The Gravedigger’s Daughter. However, in none of these examples does Oates purport to relate the precise real-life “facts” of the historical events. Indeed, for an author who believes in the multiplicity of truths such a task would be superfluous, if it was in fact possible, given what she perceives as the inherently “error-prone” nature of our species. “Language,” she writes in her essay “On Fiction in Fact,” “by its very nature tends to distort experience. With the best of intentions, in recalling the past, if even a dream of the previous night, we are already altering – one might say violating – the original experience, which may have been wordless and was certainly improvised.” In response to what she sees as the problematic nature of language, memory and the artificial nature of writing, Oates has cultivated a self-described “psychological realism” that seeks to depict a greater realm of truth beyond the world of facts, that is to say the truth of emotion and felt experience, “states of mind [which are] real enough – emotions, moods, shifting obsessions, beliefs – though immeasurable.” This article compares both fiction and non-fiction works by Oates – notably, A Widow’s Story, Sourland, The Falls – in a discussion of the fluctuating frontier between the two genres and the notion of psychological Truth that this tenuous relationship reveals.

  1. Some surprising facts about (the problem of) surprising facts (from the Dusseldorf Conference, February 2011).

    Mayo, D

    2014-03-01

    A common intuition about evidence is that if data x have been used to construct a hypothesis H, then x should not be used again in support of H. It is no surprise that x fits H, if H was deliberately constructed to accord with x. The question of when and why we should avoid such "double-counting" continues to be debated in philosophy and statistics. It arises as a prohibition against data mining, hunting for significance, tuning on the signal, and ad hoc hypotheses, and as a preference for predesignated hypotheses and "surprising" predictions. I have argued that it is the severity or probativeness of the test--or lack of it--that should determine whether a double-use of data is admissible. I examine a number of surprising ambiguities and unexpected facts that continue to bedevil this debate.

    2016-01-01

    In the process of scientific inquiry, certain claims accumulate enough support to be established as facts. Unfortunately, not every claim accorded the status of fact turns out to be true. In this paper, we model the dynamic process by which claims are canonized as fact through repeated experimental confirmation. The community's confidence in a claim constitutes a Markov process: each successive published result shifts the degree of belief, until sufficient evidence accumulates to accept the claim as fact or to reject it as false. In our model, publication bias --- in which positive results are published preferentially over negative ones --- influences the distribution of published results. We find that when readers do not know the degree of publication bias and thus cannot condition on it, false claims often can be canonized as facts. Unless a sufficient fraction of negative results are published, the scientific process will do a poor job at discriminating false from true claims. This problem is exacerbated w...

    Science is facing a "replication crisis" in which many experimental findings cannot be replicated and are likely to be false. Does this imply that many scientific facts are false as well? To find out, we explore the process by which a claim becomes fact. We model the community's confidence in a claim as a Markov process with successive published results shifting the degree of belief. Publication bias in favor of positive findings influences the distribution of published results. We find that unless a sufficient fraction of negative results are published, false claims frequently can become canonized as fact. Data-dredging, p-hacking, and similar behaviors exacerbate the problem. Should negative results become easier to publish as a claim approaches acceptance as a fact, however, true and false claims would be more readily distinguished. To the degree that the model reflects the real world, there may be serious concerns about the validity of purported facts in some disciplines.

  6. Similarity interference in learning and retrieving arithmetic facts.

    Science.gov (United States)

    De Visscher, A; Noël, M-P

    2016-01-01

    Storing the solution of simple calculations in long-term memory is an important learning in primary school that is subsequently essential in adult daily living. While most children succeed in storing arithmetic facts to which they have been trained at school, huge individual differences are reported, particularly in children with developmental dyscalculia, who show a severe and persistent deficit in arithmetic facts learning. This chapter reports important advances in the understanding of the development of an arithmetic facts network and focuses on the detrimental effect of similarity interference. First, at the retrieval stage, connectionist models highlighted that the similarity of the neighbor problems in the arithmetic facts network creates interference. More recently, the similarity interference during the learning stage was pointed out in arithmetic facts learning. The interference parameter, that captures the proactive interference that a problem receives from previously learned problems, was shown as a substantial determinant of the performance across multiplication problems. This proactive interference was found both in children and adults and showed that when a problem is highly similar to previously learned ones, it is more difficult to remember it. Furthermore, the sensitivity to this similarity interference determined individual differences in the learning and retrieving of arithmetic facts, giving new insights for interindividual differences. Regarding the atypical development, hypersensitivity-to-interference in memory was related to arithmetic facts deficit in a single case of developmental dyscalculia and in a group of fourth-grade children with low arithmetic facts knowledge. In sum, the impact of similarity interference is shown in the learning stage of arithmetic facts and concerns the typical and atypical development.

Performativity is defined as fact-generating potential of a text, i.e. its ability to gener-ate facts of two types – 1 as focusing on actual phenom-ena and 2 as cultural phenomena. Hence, the speech genre of arguing is characterized by two types of fact-generating performativity – factual (realized through ob-jection and event-correlated performativity (realized through argumentation.

  12. Assessment of Wittgenstein's Resolution to the Negative Facts

    2016-08-01

    Full Text Available he essay tries to evaluate Wittgenstein's resolution to the riddle of Russell's negative facts. That is, when we say, for example, "Tehran is not the capital of Ireland" is true, what kind of truth–maker should we consider for the negative proposition because of its truth? Surely, a negative truth–maker is so problematic and counter–intuitive. Therefore, Wittgenstein has tried to show how it can be returned to the positive truth–makers. Thus, the paper first analyzes Wittgenstein's general resolutions to the nonexistent. Then it focuses on his special resolution to the negative facts riddle, i.e. Tractatus 2.05: "The totality of existent atomic facts also determines which atomic facts do not exist". Finally, after refuting some philosophers' criticisms, it shows his resolution's positive points and possible lacks.

  3. Subtle Implicit Language Facts Emerge from the Functions of Constructions.

    Science.gov (United States)

    Goldberg, Adele E

    2015-01-01

    Much has been written about the unlikelihood of innate, syntax-specific, universal knowledge of language (Universal Grammar) on the grounds that it is biologically implausible, unresponsive to cross-linguistic facts, theoretically inelegant, and implausible and unnecessary from the perspective of language acquisition. While relevant, much of this discussion fails to address the sorts of facts that generative linguists often take as evidence in favor of the Universal Grammar Hypothesis: subtle, intricate, knowledge about language that speakers implicitly know without being taught. This paper revisits a few often-cited such cases and argues that, although the facts are sometimes even more complex and subtle than is generally appreciated, appeals to Universal Grammar fail to explain the phenomena. Instead, such facts are strongly motivated by the functions of the constructions involved. The following specific cases are discussed: (a) the distribution and interpretation of anaphoric one, (b) constraints on long-distance dependencies,

  9. AutoFACT: An Automatic Functional Annotation and Classification Tool

    Directory of Open Access Journals (Sweden)

    Lang B Franz

    2005-06-01

    Full Text Available Abstract Background Assignment of function to new molecular sequence data is an essential step in genomics projects. The usual process involves similarity searches of a given sequence against one or more databases, an arduous process for large datasets. Results We present AutoFACT, a fully automated and customizable annotation tool that assigns biologically informative functions to a sequence. Key features of this tool are that it (1 analyzes nucleotide and protein sequence data; (2 determines the most informative functional description by combining multiple BLAST reports from several user-selected databases; (3 assigns putative metabolic pathways, functional classes, enzyme classes, GeneOntology terms and locus names; and (4 generates output in HTML, text and GFF formats for the user's convenience. We have compared AutoFACT to four well-established annotation pipelines. The error rate of functional annotation is estimated to be only between 1–2%. Comparison of AutoFACT to the traditional top-BLAST-hit annotation method shows that our procedure increases the number of functionally informative annotations by approximately 50%. Conclusion AutoFACT will serve as a useful annotation tool for smaller sequencing groups lacking dedicated bioinformatics staff. It is implemented in PERL and runs on LINUX/UNIX platforms. AutoFACT is available at http://megasun.bch.umontreal.ca/Software/AutoFACT.htm.

    All retroviruses need to integrate a DNA copy of their genome into the host chromatin. Cellular proteins regulating and targeting lentiviral and gammaretroviral integration in infected cells have been discovered, but the factors that mediate alpharetroviral avian leukosis virus (ALV) integration are unknown. In this study, we have identified the FACT protein complex, which consists of SSRP1 and Spt16, as a principal cellular binding partner of ALV integrase (IN). Biochemical experiments with purified recombinant proteins show that SSRP1 and Spt16 are able to individually bind ALV IN, but only the FACT complex effectively stimulates ALV integration activity in vitro Likewise, in infected cells, the FACT complex promotes ALV integration activity, with proviral integration frequency varying directly with cellular expression levels of the FACT complex. An increase in 2-long-terminal-repeat (2-LTR) circles in the depleted FACT complex cell line indicates that this complex regulates the ALV life cycle at the level of integration. This regulation is shown to be specific to ALV, as disruption of the FACT complex did not inhibit either lentiviral or gammaretroviral integration in infected cells.IMPORTANCE The majority of human gene therapy approaches utilize HIV-1- or murine leukemia virus (MLV)-based vectors, which preferentially integrate near genes and regulatory regions; thus, insertional mutagenesis is a substantial risk. In contrast, ALV integrates more randomly throughout the genome, which decreases the risks of deleterious integration. Understanding how ALV integration is regulated could facilitate the development of ALV-based vectors for use in human gene therapy. Here we show that the FACT complex directly binds and regulates ALV integration efficiency in vitro and in infected cells. Copyright © 2017 American Society for Microbiology.

  11. FACT: functional annotation transfer between proteins with similar feature architectures.

    Science.gov (United States)

    Koestler, Tina; von Haeseler, Arndt; Ebersberger, Ingo

    2010-08-09

    The increasing number of sequenced genomes provides the basis for exploring the genetic and functional diversity within the tree of life. Only a tiny fraction of the encoded proteins undergoes a thorough experimental characterization. For the remainder, bioinformatics annotation tools are the only means to infer their function. Exploiting significant sequence similarities to already characterized proteins, commonly taken as evidence for homology, is the prevalent method to deduce functional equivalence. Such methods fail when homologs are too diverged, or when they have assumed a different function. Finally, due to convergent evolution, functional equivalence is not necessarily linked to common ancestry. Therefore complementary approaches are required to identify functional equivalents. We present the Feature Architecture Comparison Tool http://www.cibiv.at/FACT to search for functionally equivalent proteins. FACT uses the similarity between feature architectures of two proteins, i.e., the arrangements of functional domains, secondary structure elements and compositional properties, as a proxy for their functional equivalence. A scoring function measures feature architecture similarities, which enables searching for functional equivalents in entire proteomes. Our evaluation of 9,570 EC classified enzymes revealed that FACT, using the full feature, set outperformed the existing architecture-based approaches by identifying significantly more functional equivalents as highest scoring proteins. We show that FACT can identify functional equivalents that share no significant sequence similarity. However, when the highest scoring protein of FACT is also the protein with the highest local sequence similarity, it is in 99% of the cases functionally equivalent to the query. We demonstrate the versatility of FACT by identifying a missing link in the yeast glutathione metabolism and also by searching for the human GolgA5 equivalent in Trypanosoma brucei. FACT facilitates a

  12. Control, interaction mitigation and location for FACTS devices

    Science.gov (United States)

    Dong, Liangying

    This dissertation focuses on the investigation and mitigation of the potential dynamic control interactions among multiple UPFC controllers installed in power systems and the optimal location of UPFC for system stability improvement. Two different interaction phenomena are highlighted by their distinctive frequency characteristics: low frequency modal interaction and high frequency interaction. Due to the difference between the interaction phenomena, two approaches are proposed respectively to eliminate these adverse interactions. By introducing a series of additional global control signals, low frequency modal interactions can be effectively alleviated to improve system dynamic stability performance. Also, a nonlinear hybrid fuzzy logic PI controller is developed in this dissertation, which is shown to be effective in mitigating the high frequency interactions. It is indicated that the effectiveness of the FACTS device control in improving the stability mainly depends on the location of devices in the network. This dissertation develops a placement sensitivity index, which is derived from the controllability and observability factors of the system to evaluate the interaction phenomena severity. In addition, this dissertation presents the schematic and basic controls of a reconfigurable FACTS system that can be used to realize the major voltage-sourced-converter FACTS topologies. Furthermore, performance indices are developed for different FACTS devices with Energy Storage System (ESS) and dynamic responses of different FACTS combinations are presented to support the validity of the developed indices and increased controller flexibility introduced by integrating the ESS.

  13. Agriculture in Africa - Telling myths from facts: A synthesis.

    Science.gov (United States)

    Christiaensen, Luc

    2017-02-01

    Stylized facts drive research agendas and policy debates. Yet robust stylized facts are hard to come by, and when available, often outdated. The 12 papers in this Special Issue revisit conventional wisdom on African agriculture and its farmers' livelihoods using nationally representative surveys from the Living Standards Measurement Study-Integrated Surveys on Agriculture Initiative in six African countries. At times they simply confirm our common understanding of the topic. But they also throw up a number of surprises, redirecting policy debates while fine-tuning others. Overall, the project calls for more attention to checking and updating our common wisdom. This requires nationally representative data, and sufficient incentives among researchers and policymakers alike. Without well-grounded stylized facts, they can easily be profoundly misguided.

    There is no measure currently available to identify asthmatics with potential immune incompetence. We propose use of a novel scoring system called the FACT score, which is formulated based on four parameters: (1) Family history of asthma, (2) Atopic conditions, (3) Bacterial colonization and (4) Th1 versus Th2 immune profile. This was a cross-sectional study involving 16 asthmatics and 14 non-asthmatics. The first two parameters of the FACT score were obtained via a chart review and interview. For the third parameter, nasopharyngeal swab samples were cultured. The ratio of interleukin-5 to interferon-gamma for each patient was measured by peripheral blood mononuclear cells cultured with house dust mite. Antibodies to 23 pneumococcal antigens were used for humoral immunity. The FACT scores for asthmatics (mean ± SD: 5.2 ± 1.87) were higher than those for non-asthmatics (mean ± SD: 3.3 ± 1.5) (p = 0.008). Of the 16 asthmatics, 7 (44%) had 12 or more positive serotype-specific polysaccharide antibodies, whereas 12 of 14 (86%) of non-asthmatics subjects had 12 or more positive serotype-specific polysaccharide antibodies (p = 0.014). Overall, the FACT score was inversely correlated with the number of positive serotype-specific antibody levels [rho (ρ) = -0.38, p = 0.04]. The proportions of subjects with 12 or more positive serotype-specific antibodies among non-asthmatics and asthmatics below and above the median of the FACT scores were 86, 50 and 38%, respectively (p = 0.052). The FACT score may help us identify a subset of asthmatics with immune incompetence. Study findings need to be replicated in a larger study.

    Full Text Available Text-mining algorithms make mistakes in extracting facts from natural-language texts. In biomedical applications, which rely on use of text-mined data, it is critical to assess the quality (the probability that the message is correctly extracted of individual facts--to resolve data conflicts and inconsistencies. Using a large set of almost 100,000 manually produced evaluations (most facts were independently reviewed more than once, producing independent evaluations, we implemented and tested a collection of algorithms that mimic human evaluation of facts provided by an automated information-extraction system. The performance of our best automated classifiers closely approached that of our human evaluators (ROC score close to 0.95. Our hypothesis is that, were we to use a larger number of human experts to evaluate any given sentence, we could implement an artificial-intelligence curator that would perform the classification job at least as accurately as an average individual human evaluator. We illustrated our analysis by visualizing the predicted accuracy of the text-mined relations involving the term cocaine.

  10. The Role of FACT in Making and Breaking Nucleosomes

    Science.gov (United States)

    Formosa, Tim

    2011-01-01

    FACT is a roughly 180 kDa heterodimeric protein complex important for managing the properties of chromatin in eukaryotic cells. Chromatin is a repressive barrier that plays an important role in protecting genomic DNA and regulating access to it. This barrier must be temporarily removed during transcription, replication, and repair, but it also must be rapidly restored to the original state afterwards. Further, the properties of chromatin are dynamic and must be adjusted as conditions dictate. FACT was identified as a factor that destabilizes nucleosomes in vitro, but it has now also been implicated as a central factor in the deposition of histones to form nucleosomes, as an exchange factor that swaps the histones within existing nucleosomes for variant forms, and as a tether that prevents histones from being displaced by the passage of RNA polymerases during transcription. FACT therefore plays central roles in building, maintaining, adjusting, and overcoming the chromatin barrier. This review summarizes recent results that have begun to reveal how FACT can promote what appear to be contradictory goals, using a simple set of binding activities to both enhance and diminish the stability of nucleosomes.

  3. Dynamic ATC enhancement through optimal placement of FACTS controllers

    Flexible AC Transmission System (FACTS) controllers offer an effective means to enhance the power transfer capability of the network. However, the extent to which a FACTS controller can enhance Available Transfer Capability (ATC) depends on its optimal location in the system. This paper has proposed sensitivity analysis of structure preserving energy margin with respect to the control parameters of FACTS controllers for their optimal placement in the network. Two types of FACTS controllers, viz. Static Synchronous Compensator (STATCOM) and Unified Power Flow Controllers (UPFC) have been considered. The hybrid approach, combining a structure preserving and a time domain simulation method, has been utilized to compute the dynamic ATC in presence of these controllers and their impact on dynamic ATC has been analyzed. The potential energy, contributed by the STATCOM and the UPFC, has also been included in the structure preserving energy function to include their influence on transient stability. The proposed method has been tested on 39-bus New England system and a practical 246-bus Indian system. (author)

  4. FACT. New image parameters based on the watershed-algorithm

    Energy Technology Data Exchange (ETDEWEB)

    FACT, the First G-APD Cherenkov Telescope, is the first imaging atmospheric Cherenkov telescope that is using Geiger-mode avalanche photodiodes (G-APDs) as photo sensors. The raw data produced by this telescope are processed in an analysis chain, which leads to a classification of the primary particle that induce a shower and to an estimation of its energy. One important step in this analysis chain is the parameter extraction from shower images. By the application of a watershed algorithm to the camera image, new parameters are computed. Perceiving the brightness of a pixel as height, a set of pixels can be seen as 'landscape' with hills and valleys. A watershed algorithm groups all pixels to a cluster that belongs to the same hill. From the emerging segmented image, one can find new parameters for later analysis steps, e.g. number of clusters, their shape and containing photon charge. For FACT data, the FellWalker algorithm was chosen from the class of watershed algorithms, because it was designed to work on discrete distributions, in this case the pixels of a camera image. The FellWalker algorithm is implemented in FACT-tools, which provides the low level analysis framework for FACT. This talk will focus on the computation of new, FellWalker based, image parameters, which can be used for the gamma-hadron separation. Additionally, their distributions concerning real and Monte Carlo Data are compared.

  5. Subtle implicit language facts emerge from the functions of constructions

    Directory of Open Access Journals (Sweden)

    Adele Eva Goldberg

    2016-01-01

    Full Text Available Much has been written about the unlikelihood of innate, syntax-specific, universal knowledge of language (Universal Grammar on the grounds that it is biologically implausible, unresponsive to cross-linguistic facts, theoretically inelegant, and implausible and unnecessary from the perspective of language acquisition. While relevant, much of this discussion fails to address the sorts of facts that generative linguists often take as evidence in favor of the Universal Grammar Hypothesis: subtle, intricate, knowledge about language that speakers implicitly know without being taught. This paper revisits a few often-cited such cases and argues that, although the facts are sometimes even more complex and subtle than is generally appreciated, appeals to Universal Grammar fail to explain the phenomena. Instead, such facts are strongly motivated by the functions of the constructions involved. The following specific cases are discussed: a the distribution and interpretation of anaphoric one, b constraints on long-distance dependencies, c subject-auxiliary inversion, and d cross-linguistic linking generalizations between semantics and syntax.

    2006-06-15

    Unified power flow controller (UPFC) and interline power flow controller (IPFC) are FACTS devices that can control the power flow in transmission lines by injecting active and reactive voltage components in series with the lines, using power converter modules, based on an externally regulated dc-link voltage. One key issue, in this application, is to find a relationship between the injected voltage and the resulting power flow in the line. In this paper, this relationship is derived analytically, and used to design two power flow control schemes. The proposed control schemes are applicable to any series-connected FACTS controller with the capability of producing a controllable voltage. In this paper, the proposed power flow control schemes are applied to a voltage-sourced converter-based IPFC, and the resulting control performances are examined using PSCAD/EMTDC simulation package. The simulation results show the effectiveness of the proposed power flow control schemes. (author)

    Pixelized cameras of Imaging Atmospheric Cherenkov Telescopes use hollow light guides with reflective surfaces based on the Winston cone design. These cones minimize insensitive spaces between the photo sensors and shield the camera from stray background light by limiting the angular acceptance to the primary reflector area. FACT (First G-APD Cherenkov Telescope) will be the first IACT with Geiger-mode avalanche photodiodes as light sensors. Solid light concentrators complementing these sensors will be used instead of hollow Winston cones. We will present simulations and measurements of our light collector design, which was optimized for the requirements of the FACT telescope and detector, and discuss the specific differences to more traditional solutions.

  1. Network segregation in a model of misinformation and fact checking

    CERN Document Server

    Tambuscio, Marcella; Ciampaglia, Giovanni Luca; Ruffo, Giancarlo

    2016-01-01

    Misinformation under the form of rumor, hoaxes, and conspiracy theories spreads on social media at alarming rates. One hypothesis is that, since social media are shaped by homophily, belief in misinformation may be more likely to thrive on those social circles that are segregated from the rest of the network. One possible antidote is fact checking which, in some cases, is known to stop rumors from spreading further. However, fact checking may also backfire and reinforce the belief in a hoax. Here we take into account the combination of network segregation, finite memory and attention, and fact-checking efforts. We consider a compartmental model of two interacting epidemic processes over a network that is segregated between gullible and skeptic users. Extensive simulation and mean-field analysis show that a more segregated network facilitates the spread of a hoax only at low forgetting rates, but has no effect when agents forget at faster rates. This finding may inform the development of mitigation techniques ...

  2. A Static Model for Stylized Facts in Social Networks

    CERN Document Server

    Jo, Hang-Hyun; Török, János; Kertész, János; Kaski, Kimmo

    2016-01-01

    The past analyses of available datasets for social networks have given rise to a number of empirical findings that cover only some parts or aspects of the society, but leave the structure of the whole social network largely unexplored due to lack of even more comprehensive datasets. In order to model the whole social network, we assume that some properties of the network are reflected in empirical findings that are commonly featured as \\emph{stylized facts} of social networks, such as broad distributions of network quantities, existence of communities, assortative mixing, and intensity-topology correlations. Several models have been studied to generate the stylized facts, but most of them focus on the processes or mechanisms behind stylized facts. In this paper, we take an alternative approach by devising a static model for the whole social network, for which we randomly assign a number of communities to a given set of isolated nodes using a few assumptions, i.e., the community size is heterogeneous, and larg...

  3. Power system damping using fuzzy controlled facts devices

    Kazemi, Ahad; Sohrforouzani, Mahmoud Vakili [Department of Electrical Engineering, Iran University of Science and Technology, Narmak, Tehran (Iran)

    2006-06-15

    This paper presents a new approach to the implementation of the effect of FACTS devices on damping local modes and inter-area modes of oscillations based on a simple fuzzy logic proportional plus conventional integral controller in a multi-machine power system. The proposed controller uses a combination of a FLC and a PI controller. In comparison with the existing fuzzy controllers, the proposed fuzzy controller combines the advantages of a FLC and a conventional PI controller. By applying this controller to the FACTS devices such as UPFC, TCSC and SVC the damping of local modes and inter-area modes of oscillations in a multi-machine power system will be handled properly. In addition, the paper considers the conventional PI controller and compares its performance with respect to the proposed fuzzy controller. Also the effects of the auxiliary signals in damping multimodal oscillation have been shown. Finally, several fault and load disturbance simulation results are presented to highlight the effectiveness of the proposed FACTS controller in a multi-machine power system. (author)

  4. An agent-based approach to financial stylized facts

    Science.gov (United States)

    Shimokawa, Tetsuya; Suzuki, Kyoko; Misawa, Tadanobu

    2007-06-01

    An important challenge of the financial theory in recent years is to construct more sophisticated models which have consistencies with as many financial stylized facts that cannot be explained by traditional models. Recently, psychological studies on decision making under uncertainty which originate in Kahneman and Tversky's research attract a lot of interest as key factors which figure out the financial stylized facts. These psychological results have been applied to the theory of investor's decision making and financial equilibrium modeling. This paper, following these behavioral financial studies, would like to propose an agent-based equilibrium model with prospect theoretical features of investors. Our goal is to point out a possibility that loss-averse feature of investors explains vast number of financial stylized facts and plays a crucial role in price formations of financial markets. Price process which is endogenously generated through our model has consistencies with, not only the equity premium puzzle and the volatility puzzle, but great kurtosis, asymmetry of return distribution, auto-correlation of return volatility, cross-correlation between return volatility and trading volume. Moreover, by using agent-based simulations, the paper also provides a rigorous explanation from the viewpoint of a lack of market liquidity to the size effect, which means that small-sized stocks enjoy excess returns compared to large-sized stocks.

  5. Energy optimal control strategies for electro motors; low-cost and sensorless PWM-VSI based induction motor control. Vol. 1: Main report, appendix and annex

    When variable speed induction motor drives are used in applications that run at low load for long periods, energy can be saved by reducing the motor flux at low load. In this report the efficiency of 2.2 kW standard and high-efficiency motor drives are investigated experimentally with efficiency optimized and constant flux control, with sinusoidal and PWM voltage supply and with varying switching frequency. Steady-state motor models are developed and verified experimentally, and are used to analyze and develop efficiency optimizing control strategies. Four energy optimal control strategies are tested experimentally: cos({phi}) control, model-based control, off-line calculated airgap flux control and stator current/input power minimising search control. Their dynamical properties and their ability to reject load disturbances are analysed. Their ability to save energy is tested on a water pump system. For a typical predefined test-cycle the energy optimal control reduces the energy consumption with 10% compared with classical constant V/Hz control. (au)

  6. Optimization of FACTS and battery systems for supporting wind integration; Einsatzoptimierung von FACTS und Batterieanlagen zur Unterstuetzung der Windintegration

    In the future an increase of wind energy contribution for electricity generation in Germany is expected, especially regarding to the development of offshore wind farms. The fundamental difficulty lies in the optimum transfer of power for long distances using existing 380-kV voltage level. With the help of modern power electronics (FACTS) it is principally possible to influence the active power flow as well as the voltage stability. Another problem of using wind energy is the unpredictable character of the wind, which leads to a higher requirement of control power from the adjustable traditional power plants. Here, the application of modern high energy battery systems seems to be a meaningful possibility, in the case of the wind farms with a DC transmission concept. In this case, the existent voltage level can be used for the battery connection too. The present study considers the issues of the wind energy applications. The wind integration in the north and east regions requires a connection to the high voltage grid, but the number of available connection points in these regions is extremely low. The network topology of the German 380-kV grid will be simulated with the help of existing documents. For determining the optimal connection points of the planed offshore wind farms voltage stability analyses will be performed based on the simulated network. Thus, it is possible to compare the voltage behaviors of the available connection points with each other and to estimate the amount of the maximum active power injection, respectively. Furthermore, according to the network analysis with an additional wind injection, placement technologies of the FACTS devices will be developed and presented. Although the focus the studies is on static var compensators (SVC) and thyristor controlled compensators (TCSC), the methods can be used for other FACTS devices. To determine the optimum setting values of FACTS an optimal power flow problem will be formulated. Sensitivity analyses

    The article discusses theoretical as well as methodological issues of a general sociology of violence which aims at focusing on the dynamic relationship between social order, legitimacy, and physical violence. The article argues in favor of a relational approach consisting of a realistic appraisal (in an epistemological sense) of the actors' place in a locally ordered setting of relationships among objectified forms of social order, collective identities, and social interaction. The author's long term research objective is to develop a general sociology of violence grounded in social action theory, to form a basis for exploring the phenomena of physical violence in the neo-Durkheimian sense as social facts.

  19. Fact versus formula in the power spectra of complex systems

    Science.gov (United States)

    Watkins, Nick

    2016-04-01

    More than 100 years ago, Thomson and Tait's classic "Treatise on Natural Philosophy" cautioned its readers against "considering the formula and not the fact as physical reality". Deciding what the facts actually _were, however, was left as an exercise for the reader ... Complex systems offer many examples [1] of the ambiguity Thomson and Tait were trying to point out. This presentation will be about a formula-the "1/f" spectral shape seen in many areas of physics including climate science; and an empirical fact-the growth of rescaled range originally seen in river time series and now known as the Hurst effect. It is well known that Mandelbrot kicked off the study of long range dependence (LRD) in the mid 1960s [2] with a stationary model for 1/f noise and the Hurst effect. This fractional Gaussian model is now so well known that it is often seen as synonymous with both 1/f noise and the Hurst effect. However Mandelbrot himself was aware that there were other models that produced 1/f noise, including a family [3-6] which he called "conditionally stationary", with power law distributions of times between switching of states. Late in his life he re-emphasised the clear contrasts between their behaviour and that of fGn. I will explain why these other models are also physically interesting, and will show why real systems including climate examples may potentially map more closely to one or the other, or may in fact combine both aspects. I will also discuss his proposals for distinguishing between the models and how they may be implemented. [1] Watkins, Bunched Black Swans, Geophys Res.

    Joint fact-finding is a cooperative venture and communication among the participants is critical to success. Analysts have begun to recognize this and have started to adjust their craft to reflect the communicative character of their work. Non-analysts usually judge experts' opinions by their value, effectiveness, and legitimacy rather than soundness of the conclusions. Accordingly, experts must recognize the importance of these non-scientific criteria, and learn to communicate better with their non-expert colleagues. Practically, this means explaining the rationale and implications behind the

    2016-07-01

    Since October 2011, the First G-APD Cherenkov Telescope (FACT) has been collecting more than 5500 hours of physics data. Thanks to the silicon based photosensors (SiPMs, aka G-APDs), observations during bright ambient light like full moon can be carried out without degradation of the sensors. Keeping the gain of the SiPMs stable using an online feedback system, a stable and homogeneous detector performance is achieved. Based on this and an automatic data taking procedure, an unbiased longterm data sample is collected. An automatic quick look analysis provides results shortly after the data are taken allowing to send flare alerts within the same night. The main targets for FACT are the bright TeV blazars Mrk 421 and Mrk 501 which are monitored since January 2012. In addition, several other sources like for example the Crab Nebula, 1ES 1959+650, 1ES 2344+54.1 are observed. In this presentation, the results from more than four years of monitoring are summarized. Several flares from Mrk 501 and Mrk 421 are discussed in the multi-wavelength (MWL) context. Mrk 501 underwent major outbursts in June 2012 and June 2014 during the yearly MWL campaigns. Mrk 421 showed a bright flare in April 2013 where also MWL observations are available. 1ES 1959+650 showed enhanced flux in autumn 2015. Results from these observations are discussed.

  5. The Development of Reasoning about Beliefs: Fact, Preference, and Ideology.

    2013-05-01

    The beliefs people hold about the social and physical world are central to self-definition and social interaction. The current research analyzes reasoning about three kinds of beliefs: those that concern matters of fact (e.g., dinosaurs are extinct), preference (e.g., green is the prettiest color), and ideology (e.g., there is only one God). The domain of ideology is of unique interest because it is hypothesized to contain elements of both facts and preferences. If adults' distinct reasoning about ideological beliefs is the result of prolonged experience with the physical and social world, children and adults should reveal distinct patterns of differentiating kinds of beliefs, and this difference should be particularly pronounced with respect to ideological beliefs. On the other hand, if adults' reasoning about beliefs is a basic component of social cognition, children and adults should demonstrate similar belief representations and patterns of belief differentiation. Two experiments demonstrate that 5-10 year old children and adults similarly judged religious beliefs to be intermediate between factual beliefs (where two disagreeing people cannot both be right) and preferences (where they can). From the age of 5 years and continuing into adulthood, individuals distinguished ideological beliefs from other types of mental states and demonstrated limited tolerance for belief-based disagreements.

    We examined the co-activation and the selection of arithmetic facts in oral arithmetic. In two experiments, participants had to verify whether simple additions were correct or not. In Experiment 1, additions were presented in the auditory-verbal format; in Experiment 2, additions were presented in the digit format but simulating the temporal sequence of auditory problems of Experiment 1. Results were similar in both experiments. Firstly, participants took the same time to respond when an addition was incorrect but the result was that of multiplying the operands (e.g., 2+4=8) relative to a control addition with unrelated result. Secondly, participants took more time to respond when the result of multiplying the operands of the first trial was presented again in a correct addition problem (e.g., 2+6=8) relative to a control addition. This pattern of results is discussed in terms of the temporal resolution to which auditory problems are resolved and the role of an inhibitory mechanism involved in the selection of arithmetic facts.

    The First G-APD Cherenkov telescope (FACT) is the first telescope using silicon photon detectors (G-APD aka. SiPM). The use of Silicon devices promise a higher photon detection efficiency, more robustness and higher precision than photo-multiplier tubes. Since the properties of G-APDs depend on auxiliary parameters like temperature, a feedback system adapting the applied voltage accordingly is mandatory. In this presentation, the feedback system, developed and in operation for FACT, is presented. Using the extraction of a single photon-equivalent (pe) spectrum as a reference, it can be proven that the sensors can be operated with very high precision. The extraction of the single-pe, its spectrum up to 10\\,pe, its properties and their precision, as well as their long-term behavior during operation are discussed. As a by product a single pulse template is obtained. It is shown that with the presented method, an additional external calibration device can be omitted. The presented method is essential for the appl...

    Misconceptions about disasters and their social and health consequences remain prevalent despite considerable research evidence to the contrary. Eight such myths and their factual counterparts were reviewed in a classic report on the public health impact of disasters by Claude de Ville de Goyet entitled, The Role of WHO in Disaster Management: Relief, Rehabilitation, and Reconstruction (Geneva, World Health Organization, 1991), and two additional myths and facts were added by Pan American Health Organization. In this article, we reconsider these myths and facts in relation to Hurricane Katrina, with particular emphasis on psychosocial needs and behaviors, based on data gleaned from scientific sources as well as printed and electronic media reports. The review suggests that preparedness plans for disasters involving forced mass evacuation and resettlement should place a high priority on keeping families together--and even entire neighborhoods, where possible--so as to preserve the familiar and thereby minimize the adverse effects of separation and major dislocation on mental and physical health.

    Computer simulation and analysis of power systems are necessary for both planning and operation. This requires an appropriate mathematical model of the system that includes many inter-related linear/nonlinear differential and algebraic equations. Such mathematical model is also needed for the design of globally coordinated controllers to improve power system dynamic performance and stability. This paper presents a procedure for finding comprehensive dynamic models of power systems fitted with shunt and/or series connected FACTS controllers such as STATCOM, SSSC, and UPFC. In this procedure, individual components of a power system are modeled using appropriate frame of references. Then all related equations are transformed to a common network frame of reference and tied to each other through the Y-matrix of the transmission network. The procedure is tested on the Western System Coordinating Council (WSCC) test system including FACTS controllers by performing computer simulations of the system for three-phase short circuit faults. MATLAB/Simulink software package is used for the simulations. (author)

    This fact sheet is an overview of the U.S. Department of Energy's Building Technologies program. Buildings use more energy than any other sector of the U.S. economy? In fact, buildings consume more than 70% of the electricity and more than 50% of the natural gas Americans use. That's why the U.S. Department of Energy's (DOE's) Building Technologies Program (BTP) is working to improve building energy performance through high-impact research, out-reach, and regulatory efforts. These efforts will result in affordable, high-performance homes and commercial buildings. These grid-connected buildings will be more energy efficient than today's typical buildings, with renewable energy providing a portion of the power needs. They will combine energy-smart 'whole building' design and construction, appliances and equipment that minimize plug loads, and cost-effective photovoltaics or other on-site energy systems.

  11. [Renal protection in intensive care : Myths and facts].

    John, S

    2017-02-01

    Acute kidney injury (AKI) is a common and severe complication in patients on the intensive care unit with a significant impact on patient mortality, morbidity and costs of care; therefore, renal protective therapy is most important in these severely ill patients. Many renal protective strategies have been postulated during the last decades, which are sometimes still in place as a kind of "myth" but which are not always proven by evidence-based "facts". The aim of this review is therefore to question and compare some of these "myths" with the available "facts". Most important for renal protection is the early identification of patients at risk for AKI or with acute kidney damage before renal function deteriorates further. A stage-based management of AKI comprises more general measures, such as discontinuation of nephrotoxic agents and adjustment of diuretic doses but most importantly early hemodynamic stabilization with crystalloid volume replacement solutions and vasopressors, such as noradrenaline. The aim is to ensure optimal renal perfusion and perfusion pressure. Patients with known arterial hypertension potentially need higher perfusion pressures. Large amounts of hyperchloremic solutions should be avoided. Volume overload and renal vasodilatory substances can also lead to further deterioration of kidney function. There is still no specific pharmacological therapy for renal protection.

  12. Group C. Initiator paper. Periodontal regeneration--fact or fiction?

    Science.gov (United States)

    Bartold, P M

    2015-01-01

    Numerous techniques have been tried and tested to regenerate tissues lost to periodontal disease. While there has been some success to date, more work is required to move this to a reliable and clinically predictable procedure. Much of the future success for such treatments will rely largely on our understanding of the biology of both developmental and regenerative processes. Nonetheless, despite the noble goal of periodontal regeneration, the relevance of re-creation of a connective tissue attachment has been questioned. Since formation of a long junctional epithelial attachment to the tooth following a variety of periodontal treatment procedures has been shown to be no more susceptible to further breakdown than a non-diseased site, the question arises as to what purpose do we seek the ultimate outcome of periodontal regeneration? The answer lies in the "fact and fiction" of periodontal regeneration. There is no doubt that the regenerative procedures that have been developed can be shown to be biologically successful at the histological level. Furthermore, the results of periodontal regeneration (particularly guided tissue regeneration) have been stable over the long term (at least up to 10 years). However, the techniques currently under use which show the greatest promise (guided tissue regeneration and growth factors) are still clinically unpredictable because of their highly technique-sensitive nature. In addition, whether the slight clinical improvements offered by these procedures over routine open flap debridement procedures are of cost or patient benefit with regards to improved periodontal health and retention of teeth remains to be established. The next phase in regenerative technologies will undoubtedly involve a deeper understanding of the molecular signaling (both intra- and extra-cellular) and cellular differentiation processes involved in the regenerative processes. So in answer to the question of whether periodontal regeneration is fact or fiction

  14. Immune-modulating therapy in acute pancreatitis: Fact or fiction

    Science.gov (United States)

    Akinosoglou, Karolina; Gogos, Charalambos

    2014-01-01

    Acute pancreatitis (AP) is one of the most common diseases of the gastrointestinal tract, bearing significant morbidity and mortality worldwide. Current treatment of AP remains unspecific and supportive and is mainly targeted to aggressively prevent systemic complications and organ failure by intensive care. As acute pancreatitis shares an indistinguishable profile of inflammation with sepsis, therapeutic approaches have turned towards modulating the systemic inflammatory response. Targets, among others, have included pro- and anti-inflammatory modulators, cytokines, chemokines, immune cells, adhesive molecules and platelets. Even though, initial results in experimental models have been encouraging, clinical implementation of immune-regulating therapies in acute pancreatitis has had a slow progress. Main reasons include difficulty in clinical translation of experimental data, poor understanding of inflammatory response time-course, flaws in experimental designs, need for multimodal approaches and commercial drawbacks. Whether immune-modulation in acute pancreatitis remains a fact or just fiction remains to be seen in the future. PMID:25386069

    The First G-APD Cherenkov Telescope (FACT) became operational at La Palma in October 2011. Since summer 2012, due to very smooth and stable operation, it is the first telescope of its kind that is routinely operated from remote, without the need for a data-taking crew on site. In addition, many standard tasks of operation are executed automatically without the need for manual interaction. Based on the experience gained so far, some alterations to improve the safety of the system are under development to allow robotic operation in the future. We present the setup and precautions used to implement remote operations and the experience gained so far, as well as the work towards robotic operation.

    Geiger-mode avalanche photodiodes (G-APD, SiPM) are a much discussed alternative to photomultiplier tubes in Cherenkov astronomy. The First G-APD Cherenkov Telescope (FACT) collaboration builds a camera based on a hexagonal array of 1440 G-APDs and has now finalized its construction phase. A light-collecting solid PMMA cone is glued to each G-APD to eliminate dead space between the G-APDs by increasing the active area, and to restrict the light collection angle of the sensor to the reflector area in order to reduce the amount of background light. The processing of the signals is integrated in the camera and includes the digitization using the domino ring sampling chip DRS4.

    This theme issue pursues an exploration of the potential of taking into account the environmental sensitivity of development to explaining the evolution of metazoan life cycles, with special focus on complex life cycles and the role of developmental plasticity. The evolution of switches between alternative phenotypes as a response to different environmental cues and the evolution of the control of the temporal expression of alternative phenotypes within an organism's life cycle are here treated together as different dimensions of the complex relationships between genotype and phenotype, fostering the emergence of a more general and comprehensive picture of phenotypic evolution through a quite diverse sample of case studies. This introductory article reviews fundamental facts and concepts about phenotypic plasticity, adopting the most authoritative terminology in use in the current literature. The main topics are types and components of phenotypic variation, the evolution of organismal traits through plasticity, the origin and evolution of phenotypic plasticity and its adaptive value.

    The EU countries are expected to achieve by 2020 a high demanding energy policy in relation to the level of integration of renewable in their existing transmission networks. This transformation will represent significant technical challenges for the EU system operators (TSOs). Based on the aforementioned, and forecasting the large amount of wind generation that is planned to be further integrated in the Portuguese transmission network, REN is performing detailed transient stability studies to ensure that this integration takes place in a safe and reliable way and does not compromise the stability of the grid. As part of this investigation REN is interested in evaluating the capacity of FACTS devices to provide reactive support during voltage dips and to help the voltage control in the grid. The article will focus on these particular aspects and presents some particular results from a case study. (orig.)

    Full Text Available Leishmaniasis is an important parasitic infestation. This blood infestation can be seen in many tropical countries in South America, Africa, the Middle East and Indian subcontinent. Focusing on Southeast Asia, this disease is not endemic though it is also a tropical region. In the past, there are sporadic imported cases of leishmaniasis in Thailand. Within the recent year, a new species was declared from southern region of Thailand. The species, namely, Leishmania siamensis has been continuously reported in both immunocompromised and immunocompetent cases. There are several remained questions on this new species. In this specific mini-review, the authors discuss on some facts and perspectives on emerging Leishmania siamensis in Southern Thailand.
