Structures of two natural hypotensive Diels-Alder type adducts, mulberrofurans F and G, from the cultivated mulberry tree (Morus lhou Kiodz.) (1985)

Two novel 2-arylbenzofuran derivatives named mulberrofurans F and G (=albanol A), as well as albanol B (3), were isolated from the ethyl acetate extract of the root bark of cultivated mulberry tree (Japanese name "Roso, " a cultivated variety of Morus lhou KOIDZ.). The structures of mulberrofurans F and G were shown to be 1 and 2, respectively, on the basis of spectral and chemical evidence. Mulberrofurans F (1) and G (2) were derived from chalcomoracin (4) and mulberrofuran C (5), respectively, by photocyclization in acidic solution. The compounds (1, 2, and 3) are optically active and can be regarded biogenetically as variations of Diels-Alder type adducts of chalcone derivatives and a dehydroprenyl-2-arylbenzofuran derivative. Intravenous injection of mulberrofuran F (1), as well as G (2), caused a marked depressor effect in rabbit.

Modeling and Simulation for Performance Evaluation of VoIP Spam Detection Mechanism (2009)

Spam call is one of the main security threat in VoIP services. In this paper, we have designed simulation model for performance evaluation of VoIP spam defense mechanism. The simulation model has functions for performance evaluation such as calls generation and input/output comparison. Four representative caller models have been developed for performance evaluation and each model has its own characteristics as statistical parameters. The target mechanism of performance evaluation is SPIT(Spam over Internet Telephony) level decision algorithm, and we have derived SPIT levels of caller models. The performance evaluation model is designed using the DEVS formalism and DEVSJAVA is exploited for development and execution of simulation models.
Translation of <i>Drosophila melanogaster</i> sequences in <i>Escherichia coli</i> (1977)

Thirty-seven independently cloned segments of Drosophila melanogaster DNA (Dm segments) were individually tested for their ability to promote the synthesis of new polypeptides in Escherichia coli K-12. The cloning vector was the pSC101 plasmid and the test system consisted of E. coli K-12 minicells that contained the hybrid pDm plasmids. Each of four pDm plasmids produced a new polypeptide, and one, pDm107, was selected for detailed mapping of the sequences required for the translation of its 38,000-dalton polypeptide, the Dm107 protein. Mapping was accomplished by constructing (i) deletion derivatives of pDm107 and (ii) new plasmids consisting of fragments of the Dm107 segment inserted into other vectors, and then testing these hybrids for their ability to promote the synthesis of the Dm107 protein, or truncated versions of this protein, in minicells. The 1000 base pairs of sequences that are translated to yield the Dm107 protein were thereby mapped at the center of the 18,000-base pair Dm107 segment, which consists of nonrepetitive sequences located at the base of the right arm of chromosome 2. The four polypeptides produced by the four pDm plasmids require sequences of 4000 base pairs for their translation, and the total amount of DNA in the 37 cloned Dm segments that were tested is approximately 400,000 base pairs. Because no new polypeptides were detected with the remaining 33 pDm plasmids, the fraction of D. melanogaster sequences that can be efficiently translated in E. coli K-12 is estimated to be 1 x 10(-2).
Channels and codes for magnetooptical recording (1992)

The author outlines the technology used in the optical recording channel concentrating on magnetooptical recording and describes some of the major formats, codes, and data detection methods which are being developed. A sophisticated model of the optical recording channel was used as a way to make fair comparisons of these candidates, without skewing the results because of different disk or drive quality, degrees of hardware development, test procedures, etc. The author describes strengths and weaknesses of some of the leading contenders for current and future optical recording channels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Adsorption of hidrogen peroxide on the surface of silica - titania mixed oxide obtained by the sol-gel processing method (2007)

This work describes the sol-gel mixed oxide SiO2/TiO2 property, ST, as prepared, and submitted to heat treatment a 773 K, STC. SEM and EDS images show, within magnification used, a uniform distribution of the TiO2 particles in SiO2/TiO2 matrix. Both, ST and STC adsorb hydrogen peroxide on the surface and through EPR and UV-Vis diffuse reflectance spectra, it was possible to conclude that the species on the surface is the peroxide molecule attached to the Lewis acid site of titanium particle surface, alphaTi(H2O2)+. As the material is very porous, presumably the hydrogen peroxide molecule is confined in the matrix pores on the surface, a reason why the adsorbed species presents an exceptional long lived stability.
Context Free Data Cleaning and its Application in Mechanism for Suggestive Data Cleaning (2012)

Organizations are being flooded with massive transactional data. This data is of no use, if not analysed properly, to reach to any strategic decision and ultimately to achieve competitive advantage. The efficient data analysis is one of the success strategies. The analysis is highly dependent on the quality of the data. The clean data will lead to efficient data analysis. In this paper, authors suggest application of similarity metrics in context free data cleaning and a mechanism to suggest correct data based on learning from patterns derived in the prior phase. The sequence similarity metrics like Needlemen-Wunch, Jaro-Winkler, Chapman Ordered Name Compound Similarity and Smit-Watermen are used to find distance of two values. Experimental results show that how the approach not only effectively cleaning the data but suggesting suitable values in order to reduce the data entry errors.
The Effect of Privacy Concerns and Consumer Trust on Consumer Response to Online Behavioral Advertising for Travel Products (2013)

Online Behavioral Advertising (OBA) is the practice of tailoring advertising based on an individual’s online activities such as searching keywords and visiting websites. The purpose of this study is to develop a conceptual model for the OBA of travel products and examine the influence of privacy concerns and consumer trust on the acceptance of tourism OBA. Using data from 500 respondents from South Korea, hypothesized relationships were tested by Structural Equation Modeling. The results show that perceived entertainment, perceived informativeness, and perceived personalization had positive effects on attitudes towards OBA, whereas perceived irritation had a negative effect. Also, the results indicate that consumers’ privacy concerns and trust have significant impact on consumers’ intention to click on tourism OBA. Implications for management practice and further research are discussed.
An Oligo-Screening Strategy to Fill Gaps Found During Shotgun Sequencing Projects (1998)

During the course of projects to sequence human and nematode cosmids we encountered great difficulties generating contiguous sequence in regions with repetitive DNA (Alu repeats in humans and tandem or inverted repeats in the nematode). We have developed a simple and efficient strategy to fill gaps. By screening M13, plasmid or phagemid libraries with oligonucleotides flanking the gap, clones are identified that contiguate the cosmid sequence. Our method has been integrated into the GAP4 sequence assembly program. The strategy reduces both time and costs in large scale sequencing projects.
A 2.1 M Pixels, 120 Frame/s CMOS Image Sensor With Column-Parallel $\Delta \Sigma$ ADC Architecture (2010)

This paper presents a 2.1 M pixel, 120 frame/s CMOS image sensor with column-parallel delta-sigma (ΔΣ) ADC architecture. The use of a second-order ΔΣ ADC improves the conversion speed while reducing the random noise (RN) level as well. The ΔΣ ADC employing an inverter-based ΔΣ modulator and a compact decimation filter is accommodated within a fine pixel pitch of 2.25-μm and improves energy efficiency while providing a high frame-rate of 120 frame/s. A prototype image sensor has been fabricated with a 0.13-μm CMOS process. Measurement results show a RN of 2.4 e <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rms</sub> <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-</sup> and a dynamic range of 73 dB.

Coalescence-induced crystallisation wave in Pd nanoparticles (2014)

Palladium nanoparticles offer an attractive alternative to bulk palladium for catalysis, hydrogen storage and gas sensing applications. Their performance depends strongly on surface structure; therefore, nanoparticle coalescence can play an important role, as it determines the resultant structure of the active sites where reactions (e.g. catalysis) actually take place, i.e. facets, edges, vertices or protrusions. With this in mind, we performed classical molecular dynamics (MD) simulations and magnetron-sputtering inert gas condensation depositions of palladium nanoparticles, supported by high-resolution transmission electron microscopy (HRTEM), to study the mechanisms that govern their coalescence. Surface energy minimisation drove the interactions initially, leading to the formation of an interface/neck, as expected. Intriguingly, at a later stage, atomic rearrangements triggered a crystallisation wave propagating through the amorphous nanoparticles, leading to mono- or polycrystalline fcc structures. In the case of crystalline nanoparticles, almost-epitaxial alignment occurred and the formation of twins and surface protrusions were observed.
Effects of a New Alphai-Adrenoceptor Blocking Agent, 3-[2-[4-(2-Methoxyphenyl)-1-Piperazinyl]Ethyl]-(1H,3H)-Quinazoline-2,4-Dione Monohydrochloride (SGB1534), on Electrical and Mechanical Properties of Guinea-pig Mesenteric Artery (1984)

Effects of a newly synthesized alpha-adrenoceptor blocking agent, 3-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-1H, 3H)-quinazoline-2, 4-dione monochloride (SGB1534), on the electrical and mechanical properties of smooth muscles of guinea-pig mesenteric artery and on the electrical properties of smooth muscles of rat tail artery were investigated. SGB1534 (10(-10) M-10(-5) M) did not modify the membrane potential and ionic conductance of the membrane in guinea-pig mesenteric artery, but this agent did inhibit depolarizations induced by noradrenaline, phenylephrine, or histamine with similar potencies. This agent inhibited serotonin-induced depolarization, but with a weak potency. In rat tail artery, the noradrenaline-induced depolarization (10(-5) M) was inhibited by yohimbine (5 X 10(-7) M), but not by SGB1534 (10(-6) M). SGB1534 (10(-6) M) did not modify the amplitude of excitatory junction potentials (e.j.ps), the facilitation process or spike potential evoked by perivascular nerve stimulation in the mesenteric artery. Noradrenaline, phenylephrine or histamine evoked the contraction in guinea-pig mesenteric artery, and this contraction was inhibited by SGB1534 (over 10(-10) M). The serotonin-induced contraction was inhibited by higher concentrations of SGB1534 (over 10(-6) M). The concentration of SGB1534 required to inhibit the contractions evoked by these amines was much higher than that required to inhibit the depolarizations. SGB1534 (less than 10(-6) M) had no effect on the excess K-induced depolarization and contraction. These results indicate that SGB1534 possesses the property of an alpha 1-but not alpha 2-adrenoceptor blocking agent.(ABSTRACT TRUNCATED AT 250 WORDS)

Using Growing Self‐Organising Maps to Improve the Binning Process in Environmental Whole‐Genome Shotgun Sequencing (2007)

Metagenomic projects using whole-genome shotgun (WGS) sequencing produces many unassembled DNA sequences and small contigs. The step of clustering these sequences, based on biological and molecular features, is called binning. A reported strategy for binning that combines oligonucleotide frequency and self-organising maps (SOM) shows high potential. We improve this strategy by identifying suitable training features, implementing a better clustering algorithm, and defining quantitative measures for assessing results. We investigated the suitability of each of di-, tri-, tetra-, and pentanucleotide frequencies. The results show that dinucleotide frequency is not a sufficiently strong signature for binning 10 kb long DNA sequences, compared to the other three. Furthermore, we observed that increased order of oligonucleotide frequency may deteriorate the assignment result in some cases, which indicates the possible existence of optimal species-specific oligonucleotide frequency. We replaced SOM with growing self-organising map (GSOM) where comparable results are obtained while gaining 7%-15% speed improvement.
Using coordination contracts for flexible adaptation to changing business rules (2004)

We report on the use of coordination contracts, presented at the previous two IWPSE workshops, in a project for a credit recovery company. We have designed and implemented a framework that allows users to define several business rules according to predefined parameters. However, some rules require changes to the services provided by the system. For these, we use coordination contracts to intercept the calls to the underlying services and superpose whatever behaviour is imposed by the business rules applicable to that service. Such contracts can be added and deleted at run-time. Hence, our framework includes a configurator that, whenever a service is called, checks the applicable rules and configures the service with the given parameters and contracts, before proceeding with the call. Based on our experience, we put forward the position that coordination contracts facilitate the evolution of the system in order to accomodate new business rules that change the "normal" behaviour of the provided system's functionalities.
Software quality analysis by code clones in industrial legacy software (2003)

Existing research suggests that the code clone (duplicated code) is one of the factors that degrades the design and the structure of software and lowers the software quality such as readability and changeability. However, the influence of code clones on software quality has not been quantitatively clarified yet. We have tried to quantitatively clarify the relation between code clones and the software reliability and maintainability of twenty year old software. As a result, we found that modules having code clones (clone-included modules) are more reliable than modules having no code clone (non-clone modules) on average. Nevertheless, the modules having very large code clones (more than 200 SLOC) are less reliable than non-clone modules. We also found that clone-included modules are less maintainable (having greater revision number on average) than non-clone modules; and, modules having larger code clone are less maintainable than modules having smaller code clone.
Operating Standby Redundant Controller to Improve Voltage-Source Inverter Reliability (2010)

This paper presents a digital control architecture that demonstrates operating standby redundancy for a voltage-source inverter (VSI) controller. The reliability analysis shows the increased lifetime of the VSI using a standby redundant controller. The VSI control system is designed to switch from the primary to the secondary controller when a fault to the primary controller occurs. Simulated and experimental results validate that the redundant controller design switches between field-programmable gate-array-based redundant controllers with no measurable disturbance to the output voltage.

A planar diversity antenna for handheld PCS devices (1998)

A polarization diversity antenna (PDA) is described, and its performance is compared to that of a monopole antenna at frequencies near 900 MHz. Numerical modeling of each antenna, using the finite-difference time-domain (FDTD) technique, incorporates a cellular telephone handset in the vertical orientation, the user's head and hand, and the mobile communications environment. Results indicate that the two modes of the PDA are sufficiently uncorrelated for diversity operation and that, overall, the values of the mean effective gain (MEG), efficiency, and averaged specific absorption rate (SAR) in the head are better for the PDA than for the monopole antenna. However, in terms of the MEG, the PDA is more sensitive than the monopole antenna to the presence of the user's body. For the PDA, most of the power absorbed in the user's body is deposited in the hand, whereas for the monopole antenna, most of the absorbed power is deposited in the head. For both antennas, the MEG depends on the environment (urban or suburban).
A new method for measuring housekeeping performance consistency. (2006)

While the importance of housekeepers' task performance (i.e., cleaning) is undeniable, little research has been devoted to developing metrics to evaluate housekeepers' performance. This CHR report describes a pilot study implementing a metric of the overall consistency of housekeeping performance at three hotels, based on cleaning supplies used. Such an approach allows managers to evaluate the consistency of performance within the housekeeping function. Initial results show that the metric has the sensitivity to discover performance inconsistencies, suggesting the need for housekeeper training in certain circumstances. Those interested in using this approach are invited to download a research-data collection kit, and send the data to the author of this report.
