ATM Forum conformance testing to ensure your P-NNI implementation is ready to plug-and-play (2003)

As its name implies, P-NNI (private network-network interface) was originally designed for private enterprise networks. However, many public carriers are seriously considering deployment of P-NNI networks. P-NNI promises fault-tolerant, dynamic QoS routing, in a highly scalable multi-vendor plug-and-play environment. The down side to P-NNI is its complexity. The ATM Forum specification totals over six hundred pages, including errata and addenda. Clearly, it is no small task to ensure that the switch you are building conforms to standards, and will inter-operate with others. If you are building a P-NNI network, and purchasing equipment off the shelf from one or more vendors, the same questions arise. This presentation provides a brief overview of the P-NNI standard, outlines some of the factors that need to be considered when developing a P-NNI test strategy, and illustrates how conformance testing can be performed.
Table Detection from Document Image using Vertical Arrangement of Text Blocks (2015)

Table detection is a challenging problem and plays an important role in document layout analysis. In this paper, we propose an effective method to identify the table region from document images. First, the regions of interest (ROIs) are recognized as the table candidates. In each ROI, we locate text components and extract text blocks. After that, we check all text blocks to determine if they are arranged horizontally or vertically and compare the height of each text block with the average height. If the text blocks satisfy a series of rules, the ROI is regarded as a table. Experiments on the ICDAR 2013 dataset show that the results obtained are very encouraging. This proves the effectiveness and superiority of our proposed method.
Suppression of the ‘uncovering’ of mannose‐6‐phosphate residues in lysosomal enzymes in the presence of NH<sub>4</sub>Cl (1990)

The uncovering ratio of phosphate groups in lysosomal enzymes is defined as the percentage of phosphomonoester groups in the oligosaccharide side chains based on the sum of phosphomonoester and phosphodiester groups. Using a new procedure for the specific and complete hydrolysis of uncovered phosphomonoester groups in denatured immunoprecipitates of human cathepsin D, we show that the uncovering ratio varies between different forms of the enzyme and may be used as an indicator of the maturation of its carbohydrate side chains. The uncovering ratio in the total (cellular and secreted) cathepsin D from U937 promonocytes is greater than 95%. It is only slightly decreased in cells incubated in the presence of 1 alpha,25-dihydroxycholecalciferol, in which the rate of synthesis of cathepsin D is several times higher than in the control cells. In U937 cells and also in fibroblasts, the uncovering is nearly complete in intermediate and mature forms of the intracellular cathepsin D but less extensive in the intracellular and secreted precursor. In both cell types, incubation with 10 mM NH4Cl results in a decrease in the uncovering ratio of total cathepsin D. However, the activity of the uncovering enzyme, N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase, as determined with UDP-N-acetylglucosamine is not affected with up to 60 mM NH4Cl. Our results suggest that NH4Cl, in addition to its known effects on the acidic-pH-dependent functions of lysosomal compartments and of mannose-6-phosphate receptors, impairs the processing or transport of lysosomal enzyme precursors at, or proximally to, the site of the uncovering of their mannose-6-phosphate residues.
Associations between species and groups of sites: indices and statistical inference (2009)

Ecologists often face the task of studying the association between single species and one or several groups of sites representing habitat types, community types, or other categories. Besides characterizing the ecological preference of the species, the strength of the association usually presents a lot of interest for conservation biology, landscape mapping and management, and natural reserve design, among other applications. The indices most frequently employed to assess these relationships are the phi coefficient of association and the indicator value index (IndVal). We compare these two approaches by putting them into a broader framework of related measures, which includes several new indices. We present permutation tests to assess the statistical significance of species-site group associations and bootstrap methods for obtaining confidence intervals. Correlation measures, such as the phi coefficient, are more context-dependent than indicator values but allow focusing on the preference of the species. In contrast, the two components of an indicator value index directly assess the value of the species as a bioindicator because they can be interpreted as its positive predictive value and sensitivity. Ecologists should select the most appropriate index of association strength according to their objective and then compute confidence intervals to determine the precision of the estimate.
Some Recent Advances in Network Flows (1991)

The literature on network flow problems is extensive, and over the past 40 years researchers have made continuous improvements to algorithms for solving several classes of problems. However, the surge of activity concerning the algorithmic aspects of network flow problems over the past few years has been particularly striking. Several techniques have proven to be very successful in permitting researchers to make these recent contributions: (i) scaling of the problem data; (ii) improved analysis of algorithms, especially amortized worst-case performance and the use of potential functions; and (iii) enhanced data structures. This survey illustrates some of these techniques and their usefulness in developing faster network flow algorithms. The discussion focuses on the design of faster algorithms from the worst-case perspective, and is limited to the following fundamental problems: the shortest path problem, the maximum flow problem, and the minimum cost flow problem. Several representative algorithms from each problem class are considered, including the radix heap algorithm for the shortest path problem, preflow push algorithms for the maximum flow problem, and the pseudoflow push algorithms for the minimum cost flow problem.
Common Statistical Tests and Interpretation in Nursing Research (2016)

Faith community nurses need a basic understanding of common statistical tests and their interpretation to aid in the appraisal of research for evidence-based practice. The purpose of this article is to review statistical concepts, define common statistical tests, and interpret the results of statistical tests. Common statistical tests that measure differences in groups are independent samples t-test, paired sample t-tests, and analysis of variance. Common statistical tests that measure relationships are Pearson product moment correlation and chi-square. Knowledge of statistical concepts and common statistical tests assist in the appraisal of nursing research for evidence-based practice.
Microbial Enhanced Oil Recovery Pilot Test in Piedras Coloradas Field, Argentina (1999)

Abstract Extensive feasibility tests involving Microbial Improvement Technology were conducted with the two main productive formations in Piedras Coloradas Oilfield, Mendoza Province, Argentina. The program started March 1997 and continued during twelve non-consecutive months. Six producer wells, two of them horizontals, were under a systematic program of inoculations using hydrocarbon-degrading anaerobic-facultative microorganisms. A complete set of rheology parameters, specific geochemical fingerprints and biomarkers comparison was used to evaluate pre- and post-trial compositional alterations in produced fluids. Project performance in terms of fractional flow evolution was correlated with well completion configuration and reservoir petrophysics by the use of parametric models and compared on a well-by-well basis with corresponding decline and complementary baselines. Incremental Oil averages 66% over baseline with minimum values of 28.5% and maximum above 110%. Results are consistent and show a clear correlation between treatment design modifications and water cut reduction. This correlation proves that Microbial Enhanced Oil Recovery methods are controllable and predictable if team integration and proper engineering methods are observed during pilot design and well monitoring stages. Cost per Incremental Barrel (CIB) was 5.1 $/barrel during pilot stage. On MEOR Expanded scales, this value is forecast to decrease to below 2 $/barrel. The project demonstrates that this technology is cost effective, easy to implement and complies very well with local environmental regulations and biosafety issues. This pilot program is the first part of an integral mid-term strategy to use biotechnology in paraffinic oil bearing reservoirs. Further evaluations in course will be covering microbial influence mechanisms on waterflooding methods.
Chimeric analysis of <i>T (Brachyury)</i> gene function (1993)

To investigate T(Brachyury) gene function, a chimeric analysis of midgestation (9.5-11.5 days post coitum) embryos has been performed. Embryonic stem (ES) cell lines homozygous or heterozygous for the T gene have been introduced into wild-type host embryos by blastocyst injection, and the resulting chimeras scored for morphological abnormality and extent of colonization by T/T cells. As observed previously in earlier stage chimeras (Rashbass, P., Cooke, L. A., Herrmann, B. G. and Beddington, R. S. P. (1991) Nature 353, 348-350), 9.5-11.5 dpc T/T<==>+/+ chimeras exhibit many morphological features of intact T/T mutants. In addition, a dramatic bias of T/T cells towards caudal regions (such as tail and allantois) was observed in all chimeras tested. This is likely to result from accumulation of nascent T/T mesoderm cells with time near the primitive streak, possibly because of altered migration or adhesion properties. T/+ cells colonized rostral regions efficiently, but a slight bias towards the distal end of the tail was still evident. No such bias was observed in control chimeras. The presence of T/T cells in the allantois resulted in its failure to form a correct placental connection and thus arrested later development. In contrast, chimeras in which T/T cells were present predominantly in the tail developed normally but exhibited severe tail abnormalities such as foreshortening, branching and haemorrhagic cavities. Moreover, in these embryos, much higher levels of chimerism were present in the distal end of the tail than in younger (9.5 dpc) embryos. Later in gestation, such abnormal tails probably degenerated, giving rise to neonates with absent or severely abnormal tails but no evidence of chimerism. In situ analysis of T expression in the tail reveals that normally T is expressed highly in the tailbud (the growing portion of the tail) during its elongation between 9.5 and 11.5 dpc. Thus, evidence both from chimeras and from T expression in the tail suggest that T may play a role in the correct deployment of cells emerging from the tailbud.
Ischemic threshold of brain protein synthesis after unilateral carotid artery occlusion in gerbils. (1989)

The threshold of the relation between regional cerebral blood flow and regional cerebral protein synthesis was investigated in gerbils submitted to a 1-hour occlusion of the left common carotid artery. Blood flow was measured with [131I]iodoantipyrine and protein synthesis with [14C]leucine using double-tracer autoradiography and trichloroacetic acid wash-incubation for removal of nonincorporated tracer radioactivity. Specific activity of blood and brain leucine and [14C]leucine incorporation into brain proteins was also measured by conventional high-performance liquid chromatography to validate the autoradiographic approach. In control gerbils, gray matter blood flow ranged between 180 and 220 ml/100 g/min and fractional amino acid incorporation was approximately 80%. Unilateral carotid artery occlusion resulted in graded ischemia with blood flow between 10 and 100 ml/100 g/min. Regional cerebral protein synthesis gradually declined at blood flows of less than 100 ml/100 g/min and approached 0 at a blood flow of 40 ml/100 g/min. This threshold for complete suppression of protein synthesis is much higher than that for maintenance of tissue energy state and suggests that the size of an infarct after focal ischemia is determined by the suppression of protein synthesis rather than by the breakdown of energy metabolism.
The Pricing of Municipal Bonds (1982)

In recent years, increased interest has developed in municipal bonds. This interest seems to be related to higher levels of interest rates, higher marginal tax rates for individuals because of inflation, and large demand for capital funds by municipalities. In spite of this greater awareness of municipal bonds, the academic literature lacks a rigorous analysis comparing municipal bonds with other bonds. The purpose of this paper is to partially fill this gap. Since one major characteristic differentiating municipal bonds from other bonds is the (federal) tax-free status of the coupons on municipals, this paper will trace out the implications of this differential tax treatment by comparing municipal bonds with fully-taxed bonds.
p53 gene mutation: software and database (1998)

A large number of different mutations in the p53 tumor suppressor gene have been identified in all types of cancer. As of October, 1997, this database ( http://perso.curie.fr/tsoussi ) contained >7500 mutations. Such a substantial increase since our previous reports should enable epidemiological analyses which were not previously possible. In order to analyse these new data, the UMD software has been improved. A new Web version of the UMD software enables online analysis of the database. The present report describes various improvements since the last release of the database.

Mapping the active site tyrosine of Escherichia coli DNA gyrase. (1987)

We have identified tyrosine 122 of the A subunit of Escherichia coli DNA gyrase as the tyrosine that becomes covalently bound to DNA when the enzyme breaks the phosphodiester bonds of DNA. The covalent gyrase X DNA complex was isolated following cleavage of the DNA by gyrase in the presence of the gyrase inhibitor oxolinic acid. The active site tyrosine was first mapped to two overlapping peptides. Its precise position in the sequence of the A subunit of gyrase was then determined by sequencing of a peptide bound to DNA. We also present a method for mapping sites of DNA attachment in a protein of known amino acid sequence. The covalent complex of DNA and protein is treated with proteases that cut specifically. The electrophoretic mobilities of the resulting peptide-bound DNA molecules are correlated with the sizes of the bound peptides, allowing determination of the site of attachment of the DNA.
Firms Financial Performance and Human Resource Accounting Disclosure in Nigeria (2012)

The purpose of this study was to examine the relationship between firms financial performance and humanresource accounting disclosure of companies in Nigeria. Five years financial data from 2005-2009 of fifty twocompanies across all sectors as listed on the Nigeria stock exchange fact book of 2005-2009 were extracted usingsimple random sampling techniques. Descriptive, correlation and regression statistical techniques were used inanalyzing the data. Our findings show that the combined effect of Firm Financial Performance accounted for75.9% of the variation in Human Resource Accounting Disclosure (HRAD) with an F– ratio 3.581 beingsignificant at 5% confidence level. The positive correlation between Return on Equity (ROE) and HumanResource Accounting Disclosure (HRAD) supposes that an increase in return on equity encourage firm inreporting human capital information so as to establish trustworthiness with stakeholders; enhance externalreputation, appear legitimate in the public eye and avoid cost for non legitimacy. The study concludes thathuman resource accounting information of an organization is very important factor for decision makers in an eraof knowledge based economy. There is growing evidence of the interest and demand among stakeholders forinformation from firm in relation to human capital. Based on this, the study recommended among others,regulatory intervention in the accounting standard setting process for human capital reporting in Nigeria.Standard should be created for human resource identification and measurement. This will enhance valuation ofhuman capital, ensure a higher degree of utility to stakeholder, uniformity in disclosures and will allow reliablecomparison of human capital values.
[Some properties of a mutant of Streptomyces globisporus 1912 supersensitive to ultraviolet radiation]. (2005)

A well-sporulating mutant Spo 1 has been isolated after the action of defective phage from the zone of total lysis of Streptomyces globisporus 1912. It has been shown, that mutant Spo 1 is supersensitive to the action of ultraviolet radiation and has the increased sensitivity to the action of methyl-methane-sulfonate, has mutation in the cluster of genes of synthesis of landomycin E and is not sensitive to the action of nitrous acid and hydrogen peroxide. Spo 1 also has a high level of UV-mutability. After the action of UV on spores 4620 colonies were analysed and 17 auxotrophic mutants (0.36%) were selected. Four auxotrophs restored their ability to produce landomycin E and a partial block of synthesis of the antibiotic was observed in six auxotrophs. Seven of white (lnd E) auxotrophs were analysed with the help of a system "secretor-conventer" and it has been shown that two mutants do not synthesize daidzeine flavonoide and have genotype lnd E dai aux uvs, five of them were capable to synthesize this flavonoide and have genotype lnd dai(+) aux uvs. Initial species of S. globisporus 1912 has increased sensitivity to lethal action of UV. It is supposed that mutant Spo 1 bears two uvs-mutations.
De‐agglomeration and Dispersion of Nano‐TiO<sub>2</sub>in an Agitator Bead Mill (2006)

The de‐agglomeration and dispersion of nano‐TiO2 powder is little reported, although nano‐TiO2 powder has been widely used due to its unique optical properties. In this study, an agitator bead mill (MiniZETA 03E, Netzsch) accompanied with an ultrasonicator was employed to de‐agglomerate the nano‐TiO2 powder in butyl acetate, and the effects of ultrasonic pretreatment, dispersant dosage, agitation speed, solid content of TiO2 suspension, and bead diameter were systemically investigated. It is found that ultrasonic pretreatment leads to short grinding time to reach the limiting fineness, low specific energy input, and small limiting mean size. All other technical parameters have also some influence on the limiting fineness and grinding time. However, the former strongly depends on agitation speed while the latter on both agitation speed and dispersant dosage. A solvent‐borne nano‐TiO2 suspension with limiting mean size of 110 nm can be successfully result under the optimal technical conditions and showed excellent UV‐shielding property and transparence when it was incorporated into polyester/melamine coatings.
Analysis and Simulation of the Rate of Heat Release (ROHR) in Diesel Engines (2013)

As the restrictions for emissions from diesel engines are getting stricter, alternative fuels get more attention. Alternative fuels that can be used directly on already existing engines must be investigated to compare their performance with conventional fuels. When analyzing the combustion process in engines it is necessary to take into consideration the thermodynamic properties of the working medium in the cylinder, so that the characterization of combustion becomes more reliable. Using the First Law of Thermodynamics as a foundation two models are constructed for this purpose. The models are tested with measurements done on a test engine and several outputs are presented. The test working points are based on the generator and propeller loading curve, which give 8 measured cylinder pressure traces.Calculation of the speed of combustion (reaction rate) from the pressure measurements gave useful results and the performance of a test engine was calculated based on these. Integration of the reaction rates give the reaction co-ordinates (RCOs) which tells how much fuel that is burned at any time. The calculated RCOs in this case gave results that were partly impossible and the reasons for this were sought. This resulted in indications that errors in the pressure measurement method could be the cause of the partly impossible results.Small fluctuations in the pressure measurements will cause big fluctuations in the calculated reaction rate and thus rate of heat release (ROHR). The reaction rate from raw measurements can be smoothed by the aid of Vibe functions. A smoothing attempt was carried out, but the results were rather poor. The impact of the Vibe parameters is demonstrated. The developed models show results that indicate a good validity.
Novel algorithm for segmentation and automatic identification of pests on plants using image processing (2012)

Enormous agricultural yield is lost every year, due to rapid infestation by pests and insects. A lot of research is being carried out worldwide to identify scientific methodologies for early detection/identification of these bio-aggressors. In the recent past, several approaches based on automation and image processing have come to light to address this issue. Most of the algorithms concentrate on pest identification and detection, limited to a greenhouse environment. Also, they involve several complex calculations to achieve the same. In this paper, we propose a novel and unique algorithm to segregate and detect pests using image processing. The proposed methodology involves reduced computational complexity and aims at pest detection not only in a greenhouse environment but also in a farm environment as well. The whitefly, a bio-aggressor which poses a threat to a multitude of crops, was chosen as the pest of interest in this paper. The algorithm was tested for several whiteflies affecting different leaves and an accuracy of 96% of whitefly detection was achieved. The algorithm was developed and implemented using MATLAB programming language on MATLAB 7.1 build 2011a.
Feline renal ultrasonography: quantitative analyses of imaged anatomy. (1987)

Maximal kidney dimensions from serial ultrasonograms were measured in 10 healthy cats. Because clinical ultrasonographic examination is often performed in conjunction with excretory urography, the effect of radiographic contrast medium-induced diuresis on dimensional change also was evaluated. Although a slight, statistically significant increase in size was observed (compared with kidneys scanned without contrast medium), this increase could not be detected on the basis of visual image evaluation alone.
Evaluating a personal information assistant (2007)

Personal Information Assistants that search on user's behalf aim to fetch relevant documents on a regular basis. We have developed such assistant system and evaluated it using a long-term, task-oriented approach involving real users. Current evaluation methodologies are inadequate and hence have resorted to a long-term real user study. This paper describes the design and development of our system and the results of the evaluation study.
