Improving geo-spatial linked data with the wisdom of the crowds (2013)

Currently, there is more and more interest in geo-spatial data sources providing rich information about a huge number of interconnected geo-entities and points of interest located in the real world. Moreover, this kind of sources is one of the first to be published as linked open data. Noteworthy examples are the Geonames and GeoLinkedData initiatives. On the one hand, making available more data sources as linked open data allows querying the sources in an integrated way. On the other hand, it is known that content of geo-spatial data sources suffers from various drawbacks, mainly concerning data quality and conflicts. In this context, relevant feedbacks from users with specific experience and knowledge about POIs in a certain spatial region are considered valuable contributions to improve data quality and solve description conflicts. In this context, we propose a conceptual framework called M-PREGeD (Multi-Providers cRowd-Enhanced Geo linked Data) devoted to collect, organize and rank user-generated corrections and completions to improve accuracy and completeness of Geo-spatial Linked Data from different data sources. Metrics have been defined for both contributors and contents. In the framework, validated and ranked corrections and completions are stored as linked open data in a separate repository but linked to the original data sources. The repository can be queried in a combined way with the original data sources.
Rugged Large Volume Injection for Sensitive Capillary LC-MS Environmental Monitoring (2017)

A rugged and high throughput capillary column (cLC) LC-MS switching platform using large volume injection and on-line automatic filtration and filter back-flush (AFFL) solid phase extraction (SPE) for analysis of environmental water samples with minimal sample preparation is presented. Although narrow columns and on-line sample preparation are used in the platform, high ruggedness is achieved e.g., injection of 100 non-filtrated water samples did not result in a pressure rise/clogging of the SPE/capillary columns (inner diameter 300 μm). In addition, satisfactory retention time stability and chromatographic resolution were also features of the system. The potential of the platform for environmental water samples was demonstrated with various pharmaceutical products, which had detection limits (LOD) in the 0.05-12.5 ng/L range. Between-day and within-day repeatability of selected analytes were <20% RSD.
Sodium Liquid Ion Exchanger Microelectrode Used to Measure Large Extracellular Sodium Transients (1976)

A new liquid membrane microelectrode has been developed that is easily fabricated and can measure fast sodium transients in the presence of potassium interference. It responds to a sudden change in sodium activity within 1 second. The electrode has been used to provide the first direct evidence of large sodium transients in the extracellular space of the brain of the catfish.
<title>Performance of a large-area microchannel plate photon counting intensifier</title> (1994)

A 75 mm diameter microchannel plate (MCP) intensifier has been developed for astronomical applications. The intensifier incorporates a semi-transparent photocathode, three MCPs in a Z- stack configuration, and a P20 phosphor screen in a dual proximity focused arrangement. The input MCP is a thin 40:1 channel plate which is conditioned to run at low gain and hence act as an ion barrier for the succeeding 80:1 chevron pair. The intensifier has been incorporated into a CCD readout system and has undergone extensive laboratory testing. The preconditioning of these 75 mm diameter channel plates required a large area, highly uniform electron scrub beam, this has led to the development of a novel electron gun. The design of the 75 mm intensifier and the novel electron gun are described. Results from the laboratory evaluation of the intensifier are presented. Flat field illumination showed the existence of self- exciting channels in a hexagonal pattern. Finally, a future UV or x-ray detector based on this design and incorporating large area MCPs is discussed.
Karman-type Vortices in the Wake of a Rotating Circular Cylinder (1991)

Flows past a rotating circular cylinder was investigated by using the dye injection method, and a computer simulation using the Vortex-in-Cell method was carried out. Results obtained by the two methods showed a good agreements. We found out that the Strouhal number increases and the width of the wake decreases as the spin parameter, which is the ratio of the peripheral speed of the cylinder to the uniform-flow velocity, increases. It is also shown that the predominant frequency of the wake, which corresponds to the frequency forming the Karman-type vortices, depends strongly on the Reynolds number.
A worksite method for shoulder muscle fatigue measurements using EMG, test contractions and zero crossing technique (1987)

Local muscular fatigue is an important aspect of ergonomic studies. Spectral analysis of electromyographic (EMG) signals may be applied to provide a quantitative measure of the extent of muscular fatigue. The present study was aimed at methodological development of practical and reliable field studies for the shoulder region, EMG signals were recorded during short test contractions performed at regular intervals during work and at rest. Signal analysis was performed using the zero-crossing method. The results show that the zero-crossing method gives results which are as relevant as the MPF-method. The test contraction concept in conjunction with the zero-crossing technique is called Frequency Analysis of Test Contractions (FTC). An evaluation experiment on ten subjects at rest yielded the intrinsic standard deviation of the method and also revealed lateral covariation of the trapezius and infraspinatus muscles.
Seaweed: Chemical composition and potential food uses (1989)

Abstract Chemical components of seaweeds—carbohydrates, proteins and low molecular weight nitrogenous compounds, minerals, lipids, vitamins, volatile compounds, and pigments—are reviewed in relation to potential food uses. The nutritive values of seaweeds are briefly discussed. Bioactive compounds found in seaweeds are also discussed for pharmaceutical uses or toxicity. Finally, practical uses of seaweeds as food in Japan are described.
Symmetric-extension-compatible reversible integer-to-integer wavelet transforms (2003)

Symmetric extension is explored as a means for constructing nonexpansive reversible integer-to-integer (ITI) wavelet transforms for finite-length signals. Two families of reversible ITI wavelet transforms are introduced, and their constituent transforms are shown to be compatible with symmetric extension. One of these families is then studied in detail, and several interesting results concerning its member transforms are presented. In addition, some new reversible ITI structures are derived that are useful in conjunction with techniques like symmetric extension. Last, the relationship between symmetric extension and per-lifting-step extension is explored, and some new results are obtained in this regard.
Statoil Experiences and Consequences Related to Continuous Chemical Injection (2011)

Abstract Current completion solutions using Continuously Chemical Injection system faces challenges to prevent plugging of the capillary line. Where as Completion engineering principles have in the past mainly focused on the physical properties of the injection valve and mandrel, the chemists focus have been finding effective chemicals. We now experience that we need to have a system focus. The Chemical Injection Systems are not covered by any industry standards such as ISO or API, some elements are covered but none with focus on the entire system. As such Statoil has experienced that there are many other aspects and challenges linked to Chemical Injection systems that has not been explored in the past, and as a consequence Statoil has initiated an enhanced program to gain more knowledge and experience to better understand the physical and practical interlinks related to Continuous Chemical Injection. Understanding the behaviour of chemicals in vacuum or near-vacuum pressure regimes in the upper part of the capillary line is one of the keys to understand the challenges related to these completions. Through communication with other operators throughout our industry, we understand that the challenges we have experienced are also relevant for others well operations. Statoil believe in an open environment where experiences are shared within the industry to improve our and others operations and to develop more robust solutions for the future.

Background: According to previous studies, persons wearing implant-retained prostheses may create bite forces comparable to those possessing natural dentition and it has been suggested that the risk for combination syndrome increases in persons wearing mandibular implant-retained prostheses opposed to maxillary complete dentures.
Architecture and applications of a 12-bit CMOS microprocessor (1976)

In this paper, we describe the design, interface, and architectural features of a 12-bit single-chip microprocessor, the IM6100, implemented with a silicon gate complementary MOS (SiG CMOS) process. The features of CMOS circuits for operation in difficult noise, temperature, and power environments are noted. The microprocessor recognizes the instruction set of the PDP-8/E minicomputer. It is also programmed I/O interface compatible with the PDP-8/E. A unique feature of the IM6100 is the provision for a "transparent" operator console. An all-CMOS processor system with 256 × 12 RAM, 1K × 12 ROM, and a programmable asynchronous serial interface port can be built with seven LSI devices. The system dissipates 60 mW at 5 V.
Transition-metal complexes containing phosphorus ligands. Part VIII. Sulphur dioxide derivatives of rhodium, iridium, palladium, and platinum (1972)

The palladium and platinum complexes, M(PPh3)4, react with sulphur dioxide under anaerobic conditions to afford dark purple air-sensitive derivatives, M(SO2)(PPh3)3; these products undergo aerobic oxidation to form sulphatocomplexes, M(SO4)(PPh3)2,H2O. The rhodium and iridium hydrides, M′H (CO)(PPh3)3, on treatment with sulphur dioxide yield the first sulphur dioxide–hydride derivatives, ‘M′H(SO2)(CO)(PPh3)2’. The anomalous spectroscopic features of these last-named complexes are tentatively interpreted in terms of a tautomeric equilibrium involving hydride migration between the central metal atom and the co-ordinated sulphur dioxide ligand.
Synthesis of secondary ethers derived from meadowfoam oil (1998)

Abstract Secondary ethers can be obtained from meadow‐foam‐derived delta lactones or 5‐hydroxy fatty acids by using Lewis or Brønsted acid catalysts in good yield (70–90%). The conversion of δ‐lactone or 5‐hydroxy fatty acid to 5‐ethers is performed under atmospheric pressure between 67 and 125°C with 0.5–6.4 mole equivalents of acid catalyst in the presence of 2–40 equivalents of alcohol and a reaction time of 1–140 h. Acid catalysts include mineral acids, such as perchloric and sulfuric; Lewis acids, such as boron trifluoride; and heterogeneous catalysts, such as clays and ion‐exchange resins. Primary alcohols, such as methanol, butanol, decanol, and oleyl alcohol, or branched‐chain alcohols, such as 2‐ethylhexanol, can be used to make secondary ether fatty esters. The 5‐ether fatty esters and the process for their formation have not been previously known and appear to be limited to structures where stabilized cations can be formed. The novel ethers were fully characterized by nuclear magnetic resonance and gas chromatography‐mass spectrometry.
Hydrogen sulfide: a new gaseous signal molecule and blood pressure regulator (2009)

The gas hydrogen sulfide (H2S) is emerging as a novel regulator of important physiologic functions such as arterial diameter, blood flow and leukocyte adhesion. In addition, it may have antiinflammatory and antiapoptotic effects. H2S has recently attracted much interest as a potent vasorelaxative substance that may establish itself alongside another gaseous signal molecule, nitric oxide (NO). In contrast to NO, the major source of H2S in blood may be production by red blood cells or by vascular smooth muscle cells. H2S is produced from cysteine, involving the enzymes cystathionine beta-synthase and cystathionine gamma-lyase (CSE). The importance of CSE was recently demonstrated in a mouse lacking CSE which showed reduced H2S levels and developed hypertension and reduced endothelium-mediated vasorelaxation. These data establish H2S as a new and important biologic signal molecule and as a new regulator of vascular blood flow and blood pressure.
The Relationship between Fungiform Papillae Density and Detection Threshold for Sucrose in the Young Males (2008)

The aim of this study was to investigate the relationship of fungiform papillae density with taste detection thresholds for sucrose of young male adults. One hundred and eighty two subjects aged 18–23 years (mean age: 21.9 1.2 years) were included. The densities of fungiform papillae were recorded with the aid of the digital camera, and the taste detection thresholds for sucrose were detected using a modified forced-choice triangle test. The mean density of papillae within all 170 statistic participants was 92.43 2.64/cm2, for the 6-mm-diameter stained section of the tongue tip. The average detection threshold was 10.83 0.24 mmol/l, and the highest and lowest detection thresholds were 19.88 1.31 and 5.85 0.43 mmol/l, respectively. Also, an inverse correlation between the fungiform papillae density and the detection threshold was observed. Key words: fungiform papillae density, sweet detection threshold, young males

A Curve Fitting Approach Using ANN for Converting CT Number to Linear Attenuation Coefficient for CT-based PET Attenuation Correction (2015)

Energy-mapping, the conversion of linear attenuation coefficients (μ) calculated at the effective computed tomography (CT) energy to those corresponding to 511 keV, is an important step in CT-based attenuation correction (CTAC) for positron emission tomography (PET) quantification. The aim of this study was to implement energy-mapping step by using curve fitting ability of artificial neural network (ANN). Eleven digital phantoms simulated by Geant4 application for tomographic emission (GATE) and 12 physical phantoms composed of various volume concentrations of iodine contrast were used in this study to generate energy-mapping curves by acquiring average CT values and linear attenuation coefficients at 511 keV of these phantoms. The curves were built with ANN toolbox in MATLAB. To evaluate the effectiveness of the proposed method, another two digital phantoms (liver and spine-bone) and three physical phantoms (volume concentrations of 3%, 10% and 20%) were used to compare the energy-mapping curves built by ANN and bilinear transformation, and a semi-quantitative analysis was proceeded by injecting 0.5 mCi FDG into a SD rat for micro-PET scanning. The results showed that the percentage relative difference (PRD) values of digital liver and spine-bone phantom are 5.46% and 1.28% based on ANN, and 19.21% and 1.87% based on bilinear transformation. For 3%, 10% and 20% physical phantoms, the PRD values of ANN curve are 0.91%, 0.70% and 3.70%, and the PRD values of bilinear transformation are 3.80%, 1.44% and 4.30%, respectively. Both digital and physical phantoms indicated that the ANN curve can achieve better performance than bilinear transformation. The semi-quantitative analysis of rat PET images showed that the ANN curve can reduce the inaccuracy caused by attenuation effect from 13.75% to 4.43% in brain tissue, and 23.26% to 9.41% in heart tissue. On the other hand, the inaccuracy remained 6.47% and 11.51% in brain and heart tissue when the bilinear transformation was used. Overall, it can be concluded that the bilinear transformation method resulted in considerable bias and the newly proposed calibration curve built by ANN could achieve better results with acceptable accuracy.
Diversification of RTH‐Type Zeolite and Its Catalytic Application (2009)

The RTH-type zeolite (see picture) has an attractive pore structure, but its compositional variation is limited. Now, metallosilicates with the RTH-topology can be synthesized by two routes, one of which does not use structure-directing agents. Thus prepared Al-containing RTH-type zeolites exhibited a remarkable catalytic performance for the methanol-to-olefins reaction, producing propene with high selectivity.

Comparison of microbial adherence to antiseptic and antibiotic central venous catheters using a novel agar subcutaneous infection model (2003)

An agar subcutaneous infection model (agar model), which simulates the rat subcutaneous infection model (rat model), was developed to assess the ability of antimicrobial catheters to resist microbial colonization. The catheters were implanted in the agar and rat models and the insertion sites were infected immediately or on day 7, 14 or 21 post-implantation. The catheters implanted in the agar model were transferred to fresh media one day before infection on day 7, 14 or 21. The efficacy of chlorhexidine and silver sulfadiazine impregnated (CS) catheters, CS catheters with higher levels of chlorhexidine (CS+ catheters), minocycline-rifampicin (MR) catheters and silver catheters against Staphylococcus aureus and rifampicin-resistant Staphylococcus epidermidis RIF-r2 was compared in the agar and rat models. No significant difference in the adherence or the drug release was found between the in vitro and in vivo models. In both models, CS+ and MR catheters were effective against S. aureus even when infected on day 14, whereas CS catheters were colonized when challenged on day 7. CS+ catheters were effective against S. epidermidis RIF-r2, whereas MR catheters showed adherence when infected on day 7. CS+ catheters prevented colonization of all the organisms including, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Candida albicans in the agar model, whereas MR catheters were effective only against S. aureus and S. epidermidis strains. Silver catheters were ineffective against all the organisms. The agar model may be used to predict the in vivo efficacy of antimicrobial catheters against various pathogens.

Mischarging mutants of Su+2 glutamine tRNA in E. coli. I. Mutations near the anticodon cause mischarging. (1988)

In order to select the mischarging mutants of Su+2 glutamine tRNA, auxotrophic amber mutants of E. coli K12 which cannot be suppressed particularly by Su+2 were screened. By utilizing these mutants, cysam235 and metam3, several tens of mischarging mutants of Su+2 were isolated, as those conferring altered suppression patterns for a set of tester amber mutants of bacteria and phages. Nucleotide sequence analysis revealed that the mutation sites were found to be exclusively at psi 37 residue located at the 3'-end of anticodon loop, changing it to either A37 or C37. These mutants were obtained as those suppressing cysam235, and not metam3. From these, secondary mutants were selected. In these mutants suppression patterns were further altered by the additional base substitutions, capable of suppressing metam3. Such mutants were obtained exclusively from A37 and not from C37 mutant tRNA. Additional mutations to A37 were found to be either A29 or C38, which are located at the lowermost two base pairs in anticodon stem. The mischarging sites in Su+2 glutamine tRNA locate in the newly detected region of tRNA, differing from the previous case of Su+3 tyrosine or Su+7 tryptophan tRNAs. Implication of this finding is discussed on L-shaped tRNA molecule in relation to aminoacyl-tRNA synthetase recognition. Suppression patterns given by the double-mutants, A37A29 and A37C38, were consistent with the observation that the mutant tRNAs interact with tryptophanyl-tRNA synthetase.
Language recognition in ivectors space (2011)

The concept of so called iVectors, where each utterance is represented by fixed-length low-dimensional feature vector, has recently become very successfully in speaker verification. In this work, we apply the same idea in the context of Language Recognition (LR). To recognize language in the iVector space, we experiment with three different linear classifiers: one based on a generative model, where classes are modeled by Gaussian distributions with shared covariance matrix, and two discriminative classifiers, namely linear Support Vector Machine and Logistic Regression. The tests were performed on the NIST LRE 2009 dataset and the results were compared with stateof-the-art LR based on Joint Factor Analysis (JFA). While the iVector system offers better performance, it also seems to be complementary to JFA, as their fusion shows another improvement.
