Knowledge analysis on process models (2001)

Helping end users build and check process models is a challenge for many science and engineering fields. Many AI researchers have investigated useful ways of verifying and validating knowledge bases for ontologies and rules, but it is not easy to directly apply them to checking process models. Other techniques developed for checking and refining planning knowledge tend to focus on automated plan generation rather than helping users author process information. In this paper, we propose a complementary approach which helps users author and check process models. Our system, called KANAL, relates pieces of information in process models among themselves and to the existing KB, analyzing how different pieces of input are put together to achieve some effect. It builds interdependency models from this analysis and uses them to find errors and propose fixes. Our initial evaluation shows that KANAL was able to find most of the errors in the process models and suggest useful fixes including the fixes that directly point to the sources of the errors. 1
Stratospheric Ozone Depletion by Chlorofluorocarbons (Nobel Lecture) (1996)

Hope for the atmosphere is the cautiously worded resumé of F. S. Rowland based on his knowledge of the developments in recent years about the influence of the CFCs on the ozone budget. Thanks to the restrictions that came into effect in the 1990s, the concentrations of some CFCs in the atmosphere have already reached their maximum value; for others this point will be reached in the near future. Nevertheless, large ozone losses are expected in the Antarctic spring until the middle of the 21st century.
Design For A Commercial Application Of A Holographic Scanning System (1986)

A simple, low-cost, versatile holographic scanning system was developed for use with dichromated gelatin holograms or similar high-quality copies made by hologram techniques. The fabrication of the disk holographic scanner is described in detail. The optical configurations of several high-density scan patterns were generated, and they are applicable to commercial scanning requirements.
Modeling Guidelines and a Benchmark for Power System Simulation Studies of Three-Phase Single-Stage Photovoltaic Systems (2010)

This paper presents modeling guidelines and a benchmark system for power system simulation studies of grid-connected, three-phase, single-stage Photovoltaic (PV) systems that employ a voltage-sourced converter (VSC) as the power processor. The objective of this work is to introduce the main components, operation/protection modes, and control layers/schemes of medium- and high-power PV systems, to assist power engineers in developing circuit-based simulation models for impact assessment studies, analysis, and identification of potential issues with respect to the grid integration of PV systems. Parameter selection, control tuning, and design guidelines are also briefly discussed. The usefulness of the benchmark system is demonstrated through a fairly comprehensive set of test cases, conducted in the PSCAD/EMTDC software environment. However, the models and techniques presented in this paper are independent of any specific circuit simulation software package. Also, they may not fully conform to the methods exercised by all manufacturers, due to the proprietary nature of the industry.
Opioid Peptide–expressing Leukocytes (2001)

The degree of endogenous pain inhibition is proportional to the number of opioid peptide-producing cells, and distinct leukocyte lineages contribute to this function at different stages of inflammation. These mechanisms may be important for understanding pain in immunosuppressed states such as cancer, diabetes, or AIDS and for the design of novel therapeutic strategies in inflammatory diseases.
Network time slots allocation by using a time multiplexed switch in a telecommunications architecture (2002)

Network time slots are used to set up a connection during call processing. This paper proposes a design of a time multiplexed switch to allocate network time slots in a telecommunications architecture. Network time slots can be allocated by a processor in the administrative module. Network time slots allocation by using the time multiplexed switch speeds up path hunt for line-terminating calls because of fewer messages are sent to set up a path between the switching modules. This design also improves the architecture reliability for the calls that do not require trunk hunt (i.e., intra calls) allowing for path hunt when the processor in the administrative module is unavailable. The performance of a peripheral controller is analyzed to show message handling between the peripheral controller and the time multiplexed switch controller. A hardware architecture is proposed to handle the increased number of messages in the peripheral controller.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Content-dependent contrast enhancement for displays based on cumulative distribution function (2013)

Perceived contrast is one of the most important attributes affecting image quality on displays. Three dimensional digital TVs need contrast enhancement techniques to compensate for reduction in luminance levels. Also, mobile displays demand efficient contrast enhancement techniques to improve degree of visibility under outdoor viewing environment and reduce power consumptions. This paper presents a new content dependent contrast enhancement technique to improve perceived image quality on displays. It is designed for real time implementation. Pairs of reference cumulative distribution functions (CDF) of luminance level and corresponding tone mapping functions (TMFs) are generated by off-line procedure. For real time implementation, an appropriate TMF is selected by comparing the CDF of input image and reference CDFs. The selected TMF is then applied to an input image.
Reputation Scoring System Using an Economic Trust Model: A Distributed Approach to Evaluate Trusted Third Parties on the Internet (2013)

The trust anchors defined in the DNSSEC and SSL architecture make the governance of the Internet very rigidly aligned with the domain name registrars and the software vendors. The root certification authorities (root CAs) are defined ultimately and built into the software key stores of an end-user. However, the end-user is not given any criteria to distinguish the built-in root CAs so that he is unable to manage the default key store effectively. In this paper we suggest a new approach of creating a reputation score for the trusted third parties (TTPs). We evaluate each TTP based on its economic performance by counting the amount of transaction fees put on the certificate-signing transactions. Then we become able to apply different filtering algorithms to reveal the TTPs subject to automated removal from or addition to the software key stores. One of the examples' if a root or subordinate CA does not have a single buyer of SSL certificates yet, then it is not required to keep the CA in the web browser trusted certificate store. We make use of the Bit coin protocol to reveal the transaction information and guarantee the integrity of the transaction database, which is managed and stored in a P2P manner. As a result, we achieve a completely dynamic and distributed reputation scoring system, where the cost of an attack is higher than the cost of normal system operation.
Oversampling smoothness: an effective algorithm for phase retrieval of noisy diffraction intensities (2013)

Coherent diffraction imaging (CDI) is high-resolution lensless microscopy that has been applied to image a wide range of specimens using synchrotron radiation, X-ray free-electron lasers, high harmonic generation, soft X-ray lasers and electrons. Despite recent rapid advances, it remains a challenge to reconstruct fine features in weakly scattering objects such as biological specimens from noisy data. Here an effective iterative algorithm, termed oversampling smoothness (OSS), for phase retrieval of noisy diffraction intensities is presented. OSS exploits the correlation information among the pixels or voxels in the region outside of a support in real space. By properly applying spatial frequency filters to the pixels or voxels outside the support at different stages of the iterative process ( i.e. a smoothness constraint), OSS finds a balance between the hybrid input–output (HIO) and error reduction (ER) algorithms to search for a global minimum in solution space, while reducing the oscillations in the reconstruction. Both numerical simulations with Poisson noise and experimental data from a biological cell indicate that OSS consistently outperforms the HIO, ER–HIO and noise robust (NR)–HIO algorithms at all noise levels in terms of accuracy and consistency of the reconstructions. It is expected that OSS will find application in the rapidly growing CDI field, as well as other disciplines where phase retrieval from noisy Fourier magnitudes is needed. The MATLAB (The MathWorks Inc., Natick, MA, USA) source code of the OSS algorithm is freely available from http://www.physics.ucla.edu/research/imaging.
Purification and characterization of an extracellular cytolysin produced by Vibrio damsela (1985)

Large amounts of an extremely potent extracellular cytolysin produced by the halophilic bacterium Vibrio damsela were obtained free of detectable contamination with medium constituents and other bacterial products by sequential ammonium sulfate precipitation, gel filtration with Sephadex G-100, and hydrophobic interaction chromatography with phenyl-Sepharose CL-4B. The cytolysin is heat labile and protease sensitive and has a molecular weight (estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis) of ca. 69,000 and an isoelectric point of ca. 5.6. The first 10 amino-terminal amino acid residues of the cytolysin are Phe-Thr-Gln-Trp-Gly-Gly-Ser-Gly-Leu-Thr. The cytolysin was very active against erythrocytes from 4 of the 18 animal species examined (mice, rats, rabbits, damselfish) and against Chinese hamster ovary cells and was lethal for mice (ca. 1 microgram/kg, intraperitoneal median lethal dose). Lysis of mouse erythrocytes by the cytolysin is a multi-hit, at least two-step process consisting of a temperature-independent, toxin-binding step followed by a temperature-dependent, membrane-perturbation step(s).
從菸草毛狀根之型態與轉錄體探討根毛農桿菌 rol 基因之功能 (2012)

Hairy root is the tumorized tissue induced when Agrobacterium rhizogenes infects plants, and is considered as the most powerful plant secondary metabolites-producing system. The formation of hairy root have been known to related to four root inducing (rol) genes rolA, rolB, rolC, and rolD that lie in the transferred DNA (T-DNA) of A. rhizogenes root inducing (Ri) plasmid. However, no studies showed how these rol genes affect hairy root architecture. Also, there is no comprehensive –omics information of how plant cell is manipulated by the rol genes. Therefore, this study tried to answer these questions by morphological and transcriptomic analysis of tobacco hairy root induced by wild type and rol deletion mutant of A. rhizogenes. Morphological analysis revealed that lacking rolB and rolC cause impaired hairy root syndrome, while lacking rolA and rolD had little or no effects. Transcriptomic comparison of rolB / rolC deleted hairy roots compared with that of wild type indicate that RolB may positively regulate lipid transport, cellular amino acid derivative biosynthesis process, response to wounding, and response to ethylene stimulus. Meanwhile, the biological processes that may be positively regulated by RolC are response to wounding, response to chemical stimulus, carbohydrate metabolic process, and lipid transport. The results revealed how rolB and rolC affect hairy root morphology and what are the corresponding biological processes they manipulated.
A Recursive Multibody Dynamics and Sensitivity Algorithm for Branched Kinematic Chains (2000)

In this work an efficient dynamics algorithm is developed, which is applicable to a wide range of multibody systems, including underactuated systems, branched or tree-topology systems, robots, and walking machines. The dynamics algorithm is differentiated with respect to the input parameters in order to form sensitivity equations. The algorithm makes use of techniques and notation from the theory of Lie groups and Lie algebras, which is reviewed briefly. One of the strengths of our formulation is the ability to easily differentiate the dynamics algorithm with respect to parameters of interest. We demonstrate one important use of our dynamics and sensitivity algorithms by using them to solve difficult optimal control problems for underactuated systems. The algorithms in this paper have been implemented in a software package named Cstorm (Computer simulation tool for the optimization of robot manipulators), which runs from within Matlab and Simulink. It can be downloaded from the website http://www.eng.uci.edu/∼bobrow/
Cobaloxime as a catalytic chain transfer agent (1984)

Abstract Cobaloxime, synthesized from Co II acetate and dimethylglyoxime, was used as a chain transfer agent in the free radical polymerization of methyl methacrylate. It proved to be a catalytic chain transfer agent analogous to work recently reported on cobalt porphyrins. Chain transfer constants ranged from 10 3 –10 4 and were chain length dependent. Catalytic behavior was demonstrated by calculating turnover numbers which showed that each cobaloxime molecule participated in many hundreds of chain transfer reactions.
Screening for cervical intraepithelial neoplasia in north east Scotland shows fall in incidence and mortality from invasive cancer with concomitant rise in preinvasive disease (1994)

Screening has been effective in reducing the incidence of and mortality from cervical cancer in north east Scotland. Most cases and deaths occurred in unscreened women or in those who had had few smears at long intervals. An increase in cases of cervical intraepithelial neoplasia grade III in women screened for the first time occurred during 1982-91.
Randomized Phase II Study of Two Irinotecan Schedules for Patients With Metastatic Breast Cancer Refractory to an Anthracycline, a Taxane, or Both (2004)

Irinotecan is active with good tolerability in refractory MBC. Irinotecan (especially weekly) warrants additional study as monotherapy and in combination regimens in this setting.
Profiling SIEM tools and correlation engines for security analytics (2017)

Nowadays, IT organizations generate colossal amounts of data. Handling these chunks of data itself is critical in the IT world. Hence centralizing the log management system improves security thereby enhances data protection in an organization. Such enterprises require a high profiling tool that helps in managing the information and events data to improve the level of security. Security Information and Event Management (SIEM) is a procedure for security analysis that prominence an overview of security in an organization. SIEM tools collect, analyze, normalize and correlates all files and analyze data coming from the various device and give a centralized view of logs. This paper articulates an abstraction of SIEM tools and event correlation engines, furnishing a description of their technical comparative study, focusing on most popular SIEM tools and open source rule-based correlation engines and profiles them.
Comparative Proteomic Analysis of Extracellular Proteins of <i>Clostridium perfringens</i> Type A and Type C Strains (2010)

Clostridium perfringens is a medically important clostridial pathogen and an etiological agent causing several diseases in humans and animals. C. perfringens and its toxins have been listed as potential biological and toxin warfare (BTW) agents; thus, efforts to develop strategies for detection and protection are warranted. Forty-eight extracellular proteins of C. perfringens type A and type C strains have been identified here using a 2-dimensional gel electrophoresis-mass spectrometry (2-DE-MS) technique. The SagA protein, the DnaK-type molecular chaperone hsp70, endo-beta-N-acetylglucosaminidase, and hypothetical protein CPF_0656 were among the most abundant proteins secreted by C. perfringens ATCC 13124. The antigenic component of the exoproteome of this strain has also been identified. Most of the extracellular proteins were predicted to be involved in carbohydrate transport and metabolism (16%) or cell envelope biogenesis or to be outer surface protein constituents (13%). More than 50% of the proteins were predictably secreted by either classical or nonclassical pathways. LipoP and TMHMM indicated that nine proteins were extracytoplasmic but cell associated. Immunization with recombinant ornithine carbamoyltransferase (cOTC) clearly resulted in protection against a direct challenge with C. perfringens organisms. A significant rise in IgG titers in response to recombinant cOTC was observed in mice, and IgG2a titers predominated over IgG1 titers (IgG2a/IgG1 ratio, 2). The proliferation of spleen lymphocytes in cOTC-immunized animals suggested a cellular immune response. There were significant increases in the levels of gamma interferon (IFN-gamma) and interleukin 2 (IL-2), suggesting a Th1 type immune response.
Il Fuoco or the fatal portrait : the XIXth century in the Italian silent cinema (1992)

Dans les années dix de notre siècle, un genre nouveau de film s'installe en Italie aux côtés des grandes productions historiques : le cinéma des divas dont l'histoire-type tourne autour des drames d'un "ménage à trois". Il Fuoco (Giovanni Pastrone, 1915) serait, selon l'auteur, un film moderne qui, dans le même temps, garde des liens serrés avec le passé. L'influence de la littérature "décadente" d'un D'Annunzio et celle de la peinture\nacadémique (motif de la femme à moitié nue de Cabanel et de Manet) sont nettes dans\nle portrait filmique et pictural de la femme fatale. Ainsi, ce genre de film marque la fuite hors de la réalité contemporaine de la crise économique et de la guerre.
A software platform for distributed multimedia applications (2002)

The paper discusses the functionality that a platform for distributed multimedia applications should provide. Five platforms-Touring Machine, Beteus, Lakes, Medusa and IMA-are presented and evaluated. The paper then introduces a new platform that is geared towards service provision in larger networks. In this platform, application and media processing are logically and per default geographically separated. Applications reside in application pools inside the network and control sets of multimedia terminals in the periphery. The platform is built on top of CORBA, and is thus defined as a set of IDL interfaces. The platform supports application development with high level programming interfaces, and can be further enhanced with tool-kits for special application classes. A tool-kit for teleconferencing applications is presented at the end of the paper.
<i>Copa</i> Today (1965)

The Copa in the Virgilian Appendix is a fascinating but baffling piece. It has verbal connexions with the Eclogues , notably the second, and with Propertius' last book of elegies, notably iv. 2 (Vertumnus). Wilamowitz took it to be an expansion of an epigram, composed by some follower of Propertius. He thought the speaker to be the poet throughout. Büchner interprets the poem quite differently. He considers lines 18–19 and 21–22 to be interpolations. To begin with, they mix autumn fruits with summer (though by the same token the lines in Lycidas ordering various flowers for the ‘laureate hearse’ would be an interpolation: botanical purists have protested that they do not bloom simultaneously). They also contain the connexions with Propertius. Remove them and the poem is certainly a little more consistent; and Büchner is then able to argue that the poem was composed between Catullus and the Eclogues and known to Virgil. But who would want to interpolate in such a poem? At any rate, more evidence would be needed if the lines are to be discredited.
Possible involvement of NMDA receptor‐mediated transmission in barbiturate physical dependence (1994)

1. The competitive antagonists at the N-methyl-D-aspartate (NMDA) receptor, CGP39551 and CGP37849, protected against the barbiturate withdrawal syndrome in mice, as measured by ratings of convulsive behaviour on handling. 2. The effective doses of these compounds were lower than those required to prevent seizures due to NMDA in naive animals; these were in turn lower than those needed to prevent the convulsive effects of the alpha-aminobutyric acid (GABA) antagonist, bicuculline. 3. The NMDA-receptor antagonists did not alter the increase in the incidence of convulsions due to the GABAA antagonist, bicuculline, that is seen during barbiturate withdrawal, although the latencies to these convulsions during barbital withdrawal were significantly increased after CGP39551. 4. Barbiturate withdrawal did not affect the convulsive actions of NMDA, whether measured by the incidence of convulsions or by intravenous infusion. 5. The Bmax for [3H]-dizocilpine ([3H]-MK801) binding was significantly increased by chronic barbital treatment in cerebrocortical but not in hippocampal tissues, while the Kd remained unaltered in either case. 6. At 1 h and 24 h after administration of a single dose of barbitone, the Bmax for [3H]-dizocilpine binding was unaltered in cerebrocortical tissue. Acute addition of barbitone in vitro did not alter [3H]-dizocilpine binding or the displacement of binding of thienylcyclohexylpyridine.
Porous Hollow Silica Nanoparticles as Carriers for Controlled Delivery of Ibuprofen to Small Intestine (2006)

With two different methods, ibuprofen was entrapped into porous hollow silica nanoparticles (PHSNs) carriers, which were synthesized through a sol-gel route by using CaCO3 nanoparticles as the inorganic templates. By employing pressured CO2 as the loading medium, the amount of ibuprofen that was pressed into the carriers was approximately 52% higher than that by simply soaking. The drug release behaviors of the ibuprofen-loaded PHSNs were investigated in a simulated intestine juice and an artificial gastric fluid, respectively, and it demonstrated a sustained release pattern in all cases and the sample prepared under high pressure had a lower release rate in both fluids and thus owned a greater sustained drug release capacity. In the acidic artificial gastric fluid, no silica was degraded and only 16% of the loaded ibuprofen was released from the matrix in 300 min. However, much more silica was degraded in the simulated intestine juice in a shorter time and almost all the loaded ibuprofen was dissolved into the solution eventually, resulting in a quicker and complete ibuprofen release. Therefore, the PHSNs can be utilized for applications of controlled drug delivery to small intestine.
