Electrochemically Exfoliated Graphene and Graphene Oxide for Energy Storage and Electrochemistry Applications (2015)

Top-down methods are of key importance for large-scale graphene and graphene oxide preparation. Electrochemical exfoliation of graphite has lately gained much interest because of the simplicity of execution, the short process time, and the good quality of graphene that can be obtained. Here, we test three different electrolytes, that is, H2 SO4 , Na2 SO4 , and LiClO4 , with a common exfoliation procedure to evaluate the difference in structural and chemical properties that result for the graphene. The properties are analyzed by means of scanning transmission electron microscopy (STEM), Raman spectroscopy, and X-ray photoelectron spectroscopy. We then tested the graphene materials for electrochemical applications, measuring the heterogeneous electron transfer (HET) rates with a Fe(CN)6 (3-/4-) redox probe, and their capacitive behavior in alkaline solutions. We correlate the electrochemical features with the presence of structural defects and oxygen functionalities on the graphene materials. In particular, the use of LiClO4 during the electrochemical exfoliation of graphite allowed the formation of highly oxidized graphene with a C/O ratio close to 4.0 and represents a possible avenue for the mass production of graphene oxide as valid alternative to the current laborious and dangerous chemical procedures, which also have limited scalability.
Single-phase active power filters for distributed power factor correction (2002)

In this paper single-phase shunt active power filter (APF) for distributed power factor correction is presented. The APF is employed to correct the power factor of groups of loads, compensating for the load current harmonic distortion as well as for the fundamental load current displacement factor. The full-bridge voltage source inverter with a three level modulation technique is used as the APF. Theoretical analysis and experimental results of a 6 kVA APF compensating for a group of loads are provided.
Regional endemism and cryptic species revealed by molecular and morphological analysis of a widespread species of Neotropical catfish (2000)

The lower Central American landscape was fully emergent approximately three million years ago, an event which marked the beginning of the Great American biotic interchange. Freshwater fishes participated in the biotic interchange. Because primary freshwater fishes are restricted to freshwater, they provide an excellent system for investigating the interplay of historical and recent processes on the assembly, structure and diversity of the regions' aquatic ecosystems. We focused on examining the history of diversification for a species of catfish (Pimelodella chagresi) whose distribution spans multiple, isolated drainage basins across the Isthmian landscape and into north-western South America. Analysis of mitochondrial DNA haplotypes and morphological traits indicated that P. chagresi, as currently recognized, comprises a species complex. In addition, along the Pacific slope of Panama, repeated dispersion, diversification, extinction and possibly hybridization are thought to underlie a complex distribution of haplotypes. Overall, the results underscore the tremendous importance of historical processes on regional biodiversity.

Synthetic Loading of Machines (1986)

The paper describes methods of loading three-phase induction motors, without the need to connect a load to the machine's drive shaft. Two methods are described, one method uses microprocessor controlled power electronics to replace the electrical machines of an existing equivalent load technique. The second method uses microprocessor controlled power electronics to rapidly change the machine's supply frequency. If full load temperature rise is measured using the two methods described, results are obtained which are very close to those measured when using a conventional generator load.
Nuclear-enriched abundant transcript 1 as a diagnostic and prognostic biomarker in colorectal cancer (2015)

Whole blood NEAT1 expression is a novel diagnostic and prognostic biomarker of overall survival in colorectal cancer. Elevated NEAT1 may derive from neutrophils.
What is intransitive noninterference? (2003)

The term "intransitive noninterference" refers to the information flow properties required of systems like downgraders, in which it may be legitimate for information to flow indirectly, between two users but not directly. We examine the usual definition of this property in terms of a modified purge function, and show that this is a distinctly weaker property than an alternative we derive from considerations of determinism.
Sensitivity of the Entomopathogenic Fungi, Beauveria bassiana, Verticillium lecanii, and Verticillium sp. to Fungicides and Insecticides1 (1974)

Nine fungicides and 14 insecticides and acaracides were tested in vitro on various isolates of the entomopathogenic fungi, Beauveria bassiana, Verticillium lecanii and Verticillium sp. Two techniques were employed: for Verticillium, a “poisoned-bait” method, showing growth inhibition; for B. bassiana, a poisoned-agar disc method, showing inhibition of conidial germination. All chemicals except white summer oil caused some inhibition to Verticillium growth at 10−4 of the recommended dosages for use. Great variations in sensitivity toward a particular fungicide (e.g., captan, copper oxychloride, dinocap, binapacryl) were found among isolates of the same fungal species of both genera, and were also observed with some insecticides (e.g., trichlorfon and narrow-range paraffinic oil on Verticillium). Among the fungicides, benomyl (methyl 1-[butylcarbamyl]-2-benzimidazole carbamate) and maneb caused the greatest inhibition of all isolates of both genera at recommended dosages and at 10−1 concn, indicating that their use in field or grove would endanger the fungi. At recommended dosages, copper oxychloride and dinocap were the most innocuous to all the fungi (with the exception of 1 isolate of B. bassiana). Binapacryl had no effect on spore germination of B. bassiana but moderately inhibited growth of most isolates of Verticillium spp. Daconil 2787™ (tetrachloroisophthalo-nitrite) proved moderately fungitoxic to Verticillium and less so to B. bassiana. Among insecticides, sodium fluorosilicate, dichlorvos, and chloropyrifos at recommended dosages were strongly inhibitory to growth of Verticilium spp., but only sodium fluorosilicate inhibited germination of B. bassiana.
Further Characterization of the Reduced Nicotinamide Adenine Dinucleotide Phosphate:Nitrate Oxidoreductase in <i>Aspergillus nidulans</i> (1979)

The reduced nicotinamide adenine dinucleotide phosphate (NADPH):nitrate oxidoreductase (EC 1.6.6.2) from Aspergillus nidulans wild-type bi -1 was purified by means of salt fractionation, gel filtration, affinity chromatography, and polyacrylamide gel electrophoresis. Enzyme which was adsorbed on Cibacron blue agarose could be eluted with 2 mM NADPH or 2 mM oxidized NADP (NADP + ), the former being about three times more effective than the latter. About half the total NADPH:nitrate reductase activity adsorbed on agarose required elution with 1 M NaCl. This salt-elutable form remained active with NADPH and was not converted to the NADPH-elutable form after readsorption on Cibacron blue agarose. The NADPH-eluted enzyme exhibited a markedly different electrophoretic mobility than the enzyme eluted with NADP + or NaCl. After electrophoresis on polyacrylamide gels, the NADPH-eluted NADPH:nitrate reductase was separated into four proteins, two of which contained nonheme iron and exhibited reduced methyl viologen-nitrate reductase activity. None of these proteins, singly or in combination, reduced nitrate with NADPH as substrate. Difference spectra analyses and specific heme iron stains revealed the presence of cytochrome b 557 in the largest of the proteins. The molecular weights of the four proteins, which were determined from the relationship of their mobilities on varied concentrations of acrylamide gel, were 360,000, 300,000, 240,000, and 118,000. The subunit molecular weights of these, which are determined via sodium dodecyl sulfate slab gel electrophoresis, were 49,000, 50,000, and 75,000. The key role of NADPH in maintenance of the active form of the heteromultimer is further substantiated.
Anatomical Structure Sketcher for Cephalograms by Bimodal Deep Learning (2013)

Lateral cephalogram X-ray (LCX) images are essential to provide patientspecific morphological information of anatomical structures. The automatic annotation of anatomical structures in cephalograms has been performed in the biomedical engineering for nearly twenty years. Most systems only handle a portion of salient craniofacial landmark set [1, 2, 3]. Although model-based methods can produce a full set of markers [5, 7], the pattern fitting can fail to converge in blurry images. It is challenging to annotate LCX images with high fidelity. In this work, we propose a novel cephalogram sketcher system as shown in Fig. 1 for the automatic anatomical-structure annotation, especially for the blemished images due to structure overlappings and devicespecific distortions during projection. Firstly, we introduce an hierarchical extension of a pictorial model to detect anatomical structures. Secondly, the bimodal deep Boltzmann machine (DBM) is employed to sketch the structure contours. Specifically, the contour sketcher takes advantages of the path in the DBM to extract the contour definitions from the patch textures by alternating Gibbs sampling. Given a cephalogram I, the structure definition S, and the parameters Θ = (Θq,Θr) with respect to the intraand inter-layer correlations, the posterior probability distribution according to the Bayes rule is defined as P(S|I,Θ) ∝ P(I|S,Θ)P(S|Θ), where P(S|Θ) is a shape prior distribution. P(I|S,Θ) is the image likelihood given the hierarchical architecture and the model parameters. The likelihood can be factorized as a product of likelihoods of local structures.
Studies of the immunomodulatory effects of low-level infection with Ostertagia ostertagi in calves. (1989)

Possible immunomodulation by low-level infection with Ostertagia ostertagi was studied in 4-month-old calves. Six groups of 4 calves each were subjected to the following regimens: group 1--nonparasitized controls; group 2--nonparasitized, but challenge exposed at day 64 with Brucella abortus strain 19 vaccine (BA) and at day 78 with IV administration of a soluble third-stage larval (L3) antigen preparation of O ostertagi (OAG); group 3--nonparasitized, but challenge exposed at day 78 with 75 x 10(3) L3 of O ostertagi; group 4--continuously parasitized by weekly dosing with 30 x 10(3) L3 of O ostertagi; group 5--continuously parasitized by weekly dosing with 30 x 10(3) L3 of O ostertagi, then challenge exposed on day 64 with BA and on day 78 with IV inoculation of OAG; and group 6--continuously parasitized by weekly dosing with 30 x 10(3) L3 of O ostertagi, then challenge exposed on day 78 with 75 x 10(3) L3 of O ostertagi. Over the initial 10 weeks of the study, nonparasitized calves, (groups 1, 2, and 3) had higher body weight, blood lymphocyte (BL) response to phytohemagglutinin (PHA), and significantly (P less than 0.05) higher feed consumption and lymphocyte numbers, whereas parasitized calves (groups 4, 5, and 6) had higher BL responses to pokeweed mitogen (PWM) and significantly (P less than 0.05) higher neutrophil and eosinophil numbers, plasma pepsinogen (PP) values, and BL response to OAG.(ABSTRACT TRUNCATED AT 250 WORDS)
A Review of the Efficacy of Selective Serotonin Reuptake Inhibitors in Obsessive-Compulsive Disorder (1999)

The suggestion that selective serotonin reuptake inhibitors possess efficacy similar to that of clomipramine, but have a superior side effect profile, may have important implications for patients with OCD who require long-term treatment.

This paper introduces briefly the concepts relating to business rule management techniques, such as business rule, business rule classification and the components of rule-driven applications. A rule repository model for rule-driven question-answer style web application is analyzed and presented. The way how a rule-driven question-answer-based web application works with the repository model is described.
A study on e-mail image spam filtering techniques (2013)

Spam filters are the most used software tool used by businesses and individual to block spam mails entering into their mail boxes. Until recently, majority of research effort was expended on controlling text-based spam emails. However, the past few years have envisaged a novel approach, where the spammers embed the text message into an image. Thus, the anti-spam filtering research is forced to move from text-based techniques to image-based techniques. Spam and the spam blockers designed to combat it have spawned an upsurge in creativity and innovation. Many software developers are developing new and every more effective spam filtering software. All the methods have a common dream that is to eliminate 100% of the spam, which is still not a reality. To reduce the gap between this reality and dream, researchers have proposed many different types of spam filters and this paper provides a review of them.
Self-Flushing in EDM Drilling of Ti6Al4V Using Rotating Shaped Electrodes (2019)

This article reports an experimental investigation of the efficacy of self-flushing in the Electrical Discharge Machining (EDM) process in terms of tool wear rate (TWR), hole taper angle and material removal rate (MRR). In addition to a plain cylindrical shape, electrodes of different cross sections (slotted cylindrical, sharp-cornered triangular, round-cornered triangular, sharp-cornered square, round-cornered square, sharp-cornered hexagonal and round-cornered hexagonal) were designed as a means of inducing debris egress and then fabricated in graphite. EDM drilling trials using the rotating shaped electrodes were carried out on a Ti6Al4V workpiece. The results revealed that, although a low TWR and minimum hole taper angle were achieved using a plain cylindrical electrode, the usage of rotating shaped electrodes provided self-flushing of the dielectric fluid during the EDM process, which led to an improvement in MRR compared to that achieved with a plain cylindrical electrode. Besides, in general, the electrodes with rounded corners are associated with a lower TWR, a lower hole taper angle and a higher MRR when compared to the electrodes with sharp corners. Considering these results, it was concluded that different process attributes, i.e., TWR, hole taper angle and MRR, are all greatly affected by the electrode shape, and thus, the proper selection of the electrode shape is a precondition to attain a specific response from the EDM process.

Force and Moment Plots from Pacejka 2002 Magic Formula Tire Model Coefficients (2010)

Abstract : One of the important aspects in vehicle dynamics simulation is accurate modeling of the tire-road interaction forces because the movement of the vehicle depends on the forces and moments applied to the tires. Many vehicle simulation programs such as MSC Software ADAMS, Altair HyperWorks MotionSolve, etc. use the Magic Formula (MF) developed by Pacejka to model tires. In order to use these applications more effectively, a tool was developed using MATLAB to quickly calculate and plot the forces and moments represented by the tire coefficients. The tool is consistent with expected results in determining the tire-road interaction forces. This report describes the structure of the program and how to use the Pacejka Plot Tool to plot the forces and moments from the coefficients using the PAC2002 MF tire model.
Pseudozyma pruni sp. nov., a novel ustilaginomycetous anamorphic fungus from flowers in Taiwan (2009)

Two ustilaginomycetous anamorphic strains were isolated from flowers in Taiwan. Phylogenetic analysis based on the combined rRNA gene sequence of internal transcribed spacer 1 (ITS1)-5.8S-ITS2 and large-subunit D1/D2 domains indicated that the closest recognized species was Pseudozyma fusiformata. The results of DNA-DNA hybridization and physiological characteristics showed that the two strains represent a novel species within the genus Pseudozyma. The name Pseudozyma pruni sp. nov. is proposed, with FIRDI 005(T) (=BCRC 34227(T) =CBS 10937(T)) as the type strain.
Excitation versus Emission Spectra as a Means to Examine Selective Fluorescence Quenching Agents (1992)

To ascertain whether fluorescence quenching is best studied with the use of excitation or emission spectra, and to expand our existing PAH spectral data file, we have recorded excitation spectra of benzo[b]perylene, dibenzo[hi,wx]heptacene, tetrabenzo[de,hi,mn,qr]naphthacene, perylene, benzo[a]fluoranthene, benzo[def]indeno[1,2,3hi]chrysene, naphtho[2,1a]fluoranthene, naphtho[2,3b]fluoranthene, benzo[k]fluoranthene, 2-azapyrene, naphtho[8,1,2hij]pyreno[9,10,1def]phthalazine, indeno[1,-2,3ij]isoquinoline, benzo(lmn][3,8]phenanthroline, and 7-methyldibenzo(b,def]chrysene at various nitromethane concentrations. Results of these measurements verify our earlier observations concerning the nitromethane selective quenching rule and further illustrate the importance of considering inner-filtering artifacts in quenching studies.
Simple relational correctness proofs for static analyses and program transformations (2004)

We show how some classical static analyses for imperative programs, and the optimizing transformations which they enable, may be expressed and proved correct using elementary logical and denotationaltechniques. The key ingredients are an interpretation of program properties as relations, rather than predicates, and a realization that although many program analyses are traditionally formulated in very intensional terms, the associated transformations are actually enabled by more liberal extensional properties.We illustrate our approach with formal systems for analysing and transforming while-programs. The first is a simple type system which tracks constancy and dependency information and can be used to perform dead-code elimination, constant propagation and program slicing as well as capturing a form of secure information flow. The second is a relational version of Hoare logic, which significantly generalizes our first type system and can also justify optimizations including hoisting loop invariants. Finally we show how a simple available expression analysis and redundancy elimination transformation may be justified by translation into relational Hoare logic.
SciQL, A query language for science applications (2010)

Scientific applications are still poorly served by contemporary re-lational database systems. At best, the system provides a bridge towards an external library using user-defined functions, explicit import/export facilities or linked-in Java/C # interpreters. Time has come to rectify this with SciQL1, a SQL-query language for science applications with arrays as first class citizens. It provides a seam-less symbiosis of array-, set-, and sequence- interpretation using a clear separation of the mathematical object from its underlying storage representation. The language extends value-based grouping in SQL with struc-tural grouping, i.e., fixed-sized and unbounded groups based on explicit relationships between its index attributes. It leads to a gen-eralization of window-based query processing. The SciQL architecture benefits from a column store system with an adaptive storage scheme, including keeping multiple represen-tations around for reduced impedance mismatch. This paper is fo-cused on the language features, its architectural consequences and extensive examples of its intended use. 1.

Germination of <i>Clostridium cylindrosporum</i> Spores on Medium Containing Uric Acid (1989)

Clostridium cylindrosporum spores germinated rapidly under reducing conditions when bicarbonate, uric acid, and calcium were present. Germination rates on 10 mM urate increased with increasing Ca (maximum rate at 5 mM Ca or greater). Germination rates on urate (limiting Ca) increased with increasing urate concentrations to 10 mM urate. At 10 mM Ca, germination rates reached a maximum at 1 mM urate and remained constant thereafter. Cations (Na, K, Li, and Mg), purines, purine analogs, and EDTA inhibited germination at limiting calcium concentrations but not (except for 10 mM adenine) at 10 mM Ca. Methyl viologen or formate did not inhibit germination. Germination was not observed in solutions containing xanthine, hypoxanthine, caffeine, theophylline, 6,8-dihydroxypurine, adenine, allopurinol, formate, glycine, or acetate, even though some of the purines are growth substrates.
North America’s first 1.3-μm laser transmission system (1981)

The first operational long-wavelength laser telephone trunking system in North America is described. The actual link is 17.1 km long, and no repeaters are used. The 44.7-Mbit/sec FT-3 system system design is such that the link span could be extended to over 21 km without repeaters and still maintain a 6-dB link margin. A route map of the system installation site near Washington, D.C. is shown in Fig. 1.
