Evaluation of OntoLearn, a Methodology for Automatic Learning of Domain Ontologies (2005)

Ontology evaluation is a critical task, even more so when the ontology is the output of an automatic system, rather than the result of a conceptualization effort produced by a team of domain specialists and knowledge engineers. This paper provides an evaluation of the OntoLearn ontology learning system. The proposed evaluation strategy is twofold: first, we provide a detailed quantitative analysis of the ontology learning algorithms. Second, we automatically generate natural language descriptions of formal concept specifications in order to facilitate per-concept qualitative analysis by domain specialists.
Nonstructural proteins NS2 of minute virus of mice associate in vivo with 14-3-3 protein family members (1996)

The nonstructural NS2 proteins of the prototype strain of minute virus of mice (MVMp) were previously shown to be involved in parvoviral DNA amplification as well as in efficient virus production in a host cell-specific manner (L. K. Naeger, N. Salomé, and D. J. Pintel, J. Virol. 67:1034-1043, 1993). NS2 polypeptides were also reported to participate in the cytotoxic activity of parvoviruses (C. Legrand, J. Rommelaere, and P. Caillet-Fauquet, Virology 195:149-155, 1993), for which transformed cells are preferential targets. To identify cellular partners of NS2 proteins, coimmunoprecipitation experiments were performed with various antibodies directed against the parvoviral products. Two cellular proteins with molecular masses of 30 and 32 kDa were found to associate in vivo with the NS2 polypeptides. From amino acid sequence homology, these NS2 partners were assigned to the 14-3-3 family of cellular proteins, showing at least partial identity with the epsilon and beta or zeta 14-3-3 isoforms. In agreement with this assignment, NS2-30/32-kDa protein immune complexes displayed an activating function for exoenzyme S in vitro, a hallmark of 14-3-3 polypeptides. Interactions with 14-3-3 proteins did not appear sufficient for NS2 functions, since they were not disrupted by NS2 C-terminal modifications that impaired virus replication. Binding of NS2 to 14-3-3 proteins was detected in various cells of mouse, rat, hamster, monkey, and human origin, irrespective of NS2 dispensability and host cell transformation or permissiveness. The ubiquitous 14-3-3 proteins were recently reported to associate with several other cellular or viral polypeptides involved in signal transduction and/or cell cycle regulation pathways (A. Aitken, Trends Biochem. Sci. 20:95-97, 1995). The NS2 products may connect with one of these pathways through their interaction with specific 14-3-3 polypeptides.
Catalytic oxidation of methane over noble metals (1969)

The complete oxidation of methane over palladium, platinum, rhodium and iridium has been studied using a microcalorimetric technique. The results indicated that methane may be adsorbed on two types of reaction site, one of which also adsorbs oxygen. The activation energies are proportional to the Pauling bond energies of the oxygen-metal bond in the region where the order in oxygen is low.
Vapor Deposition and Properties of Binary Arsenosilicate Glass Films (1972)

The deposition characteristics of an argon‐diluted reaction system for the chemical vapor deposition of binary arsenosilicate glass films have been studied systematically as a function of substrate temperature and flow rates of the reactants. Film composition in the range 0 to 20 mole per cent (m/o) can be controlled reproducibly at deposition rates as high as 1000Aå min−1. Properties such as composition uniformity, etch rate, d‐c dielectric strength, and moisture resistance have been measured and their compositional dependence determined.

Superoxide Ion: Generation and Chemical Implications (2016)

Superoxide ion (O2(•-)) is of great significance as a radical species implicated in diverse chemical and biological systems. However, the chemistry knowledge of O2(•-) is rather scarce. In addition, numerous studies on O2(•-) were conducted within the latter half of the 20th century. Therefore, the current advancement in technology and instrumentation will certainly provide better insights into mechanisms and products of O2(•-) reactions and thus will result in new findings. This review emphasizes the state-of-the-art research on O2(•-) so as to enable researchers to venture into future research. It comprises the main characteristics of O2(•-) followed by generation methods. The reaction types of O2(•-) are reviewed, and its potential applications including the destruction of hazardous chemicals, synthesis of organic compounds, and many other applications are highlighted. The O2(•-) environmental chemistry is also discussed. The detection methods of O2(•-) are categorized and elaborated. Special attention is given to the feasibility of using ionic liquids as media for O2(•-), addressing the latest progress of generation and applications. The effect of electrodes on the O2(•-) electrochemical generation is reviewed. Finally, some remarks and future perspectives are concluded.
Analysis of Tissue Chimerism in Nude Mouse Brain and Abdominal Xenograft Models of Human Glioblastoma Multiforme: What Does It Tell Us About the Models and About Glioblastoma Biology and Therapy? (2000)

In situ hybridization coupled to immunohistochemistry for antigens of interest allows unequivocal identification of tumor cells from reactive stroma cells and normal adjacent structures in human glioblastoma multiforme grafts transplanted into nude mice. With this methodology, we have explored the development of glioblastoma multiforme solid grafts transplanted into nude mouse brains or flanks. The brain transplants closely resembled the human situation, particularly in relation to differentiation and growth patterns. The morphological features of peritumoral reactive gliosis were similar to those observed in humans. A mouse glial stroma within the main tumor masses was also demonstrated. Kinetic studies showed that the compartment of isolated tumor cells that infiltrated host brains and the reactive gliosis constituted two cycling cell populations. Despite VEGF protein expression by tumor cells and some reactive astrocytes, the abnormally permeable microvascular beds were not hyperplastic. The observation of a non-infiltrative pattern of growth when grafts were established in host flanks demonstrated that the organ-specific environment plays a determining role in the growth and invasive properties of glioblastoma. The phylogenetic distance between man and mouse and the recipient immunoincompetence should not impose serious limitations on the use of this model for studying malignant glioma biology and therapy in vivo.
Estimating the accuracy of screening mammography (1998)

The accuracy of mammography should be recognized and included in discussions about policies for screening for breast cancer. This meta-analysis, by quantifying the expected TPR/FPR, should assist program planners, physicians, and women to understand better the cost and clinical implications of such screening programs.
Enterobacter cloacae: Bacteremia, Epidemiology, and Antibiotic Resistance (1982)

From the clinical viewpoint, Enterobacter cloacae and Enterobacter aerogenes are the two most important species of the genus Enterobacter. E. cloacae lacks lysine and arginine decarboxylases, whereas E. aerogenes has these enzymes. Enterobacter currently accounts for 40%–12% of all cases of gram-negative bacteremia although it is not a cause of bacteremia at some hospitals. This study showed that E. cloacae has been endemic at a medical center hospital for at least five years and caused 4.5% of all cases of bacteremia in 1978. In May 1977 and July 1979 outbreaks of bacteremia due to E. cloacae occurred in the burn ward of the hospital. Most infected patients had multiple sites (urine, wound, and sputum) colonized before bacteremia occurred. No environmental or personnel sources of E. cloacae in the burn ward were discovered. Isolates of E. cloacae from the second outbreak were resistant to tobramycin, amikacin, and silver nitrate. The plasmid content of these strains differed from those of the first outbreak. For a five-year period, most strains of E. cloacae were resistant to cephalothin and ampicillin; however, resistance to aminoglycosides was rare. A literature review disclosed that E. cloacae has become prominent in burn units, but that it also has caused serious infections in nonburned patients. E. cloacae tends to contaminate various medicinal, iv, and other hospital products. Therefore, bacteremia due to E. cloacae, should prompt an investigation of exposures to potentially contaminated materials, especially those introduced into the bloodstream. Therapy of E. cloacae infections remains problematic and is complicated by the emergence of multiresistant strains. Aminoglycosides are the most active agents against E. cloacae, but new agents such as cefotaxime, cefaperazone, moxalactam, and thienamycin are active and eventually may be valuable in single-drug therapy of infection due to E. cloacae.
Tunable Young's Modulus in Carbon MEMS Using Graphene-Based Stiffeners (2013)

Carbon composite micro-electromechanical systems (C-MEMS) incorporating 2 wt.% graphene stiffeners show a 65% increase in Young's modulus and 11% increase in conductivity. An improved reduced graphene oxide (iRGO), is blended into pyrolytic carbon beams prepared for resonant frequency testing. Designed around a 10:1 (length: width) aspect ratio, the linearity of wt.% iRGO in the cantilevers as a function of resonant frequencies is evaluated. The collection of the 1st through 3rd bending modes using laser doppler velocimetery (LDV) of the graphene filled cantilevers shows an increase in frequency response with nanomaterial loading (wt.%). A model was developed using the 3-bending modes and correlated with cross sectional geometry and density to extract a Young's modulus.
Need For Cognition As A Moderator Of Affective And Cognitive Elements In Online Attitude Toward The Brand Formation (2011)

<p class="MsoNormal" style="text-align: justify; line-height: normal; margin: 0in 0.5in 0pt;"><span style="font-family: &quot;Times New Roman&quot;,&quot;serif&quot;; color: black; font-size: 10pt;">Previous research on the web using traditional attitude formation models &ndash; dual mediation hypothesis (DMH) and affect transfer hypothesis (AFH) &ndash; suggests that DMH holds only for those with high need for cognition. This study examines need for cognition (NFC) as a moderator of the individual contributions of affective and cognitive elements on attitude toward the brand in an online setting. Findings show that as need for cognition increases, the effect of the creative elements in the ad on attitude toward the brand formation is lessened. The opposite effect occurs for cognitive ad elements. Our results further suggest a significant interaction effect of NFC with attitude toward the advertisement.</span></p>

Joint call admission control algorithm for reducing call blocking/dropping probability in heterogeneous wireless networks supporting multihoming (2010)

A heterogeneous wireless network supporting multihoming gives multi-mode terminals the flexibility to be simultaneously connected to more than one radio access technologies (RATs). Existing joint call admission control (JCAC) algorithms designed for heterogeneous wireless networks block or drop an incoming call when none of the available individual RATs in the heterogeneous network has enough bandwidth to support the incoming call. Consequently, high bandwidth-demanding calls can easily be blocked or dropped in the network, especially during the peak hours. In order to reduce this problem of call blocking/dropping, this paper proposes a JCAC algorithm that selects multiple RATs for an incoming call when none of the available individual RATs has enough bbu to accommodate the incoming call. Selection of multiple RATs for an incoming call entails that the packet stream of the incoming call will be split among the selected RATs. The aim of the proposed JCAC algorithm is to admit an incoming call (that cannot be admitted into any of the available single RATs because of high load in the RATs) into two or more RATs. The residual bandwidths in the selected RATs are combined to support the incoming call, and the packet stream of the call is split among the selected RATs, thereby reducing call blocking/dropping probability. At the receiver, the split packet streams are then combined. An analytical model is developed for the proposed JCAC algorithm, and its performance is evaluated in terms of call blocking/dropping probability. Simulation results show that the JCAC algorithm reduces call blocking/dropping probability in heterogeneous wireless networks supporting multihoming.
Electronically switchable slot antenna fed by microstrip line (2002)

Switching of antennas can be done with active components like PIN diodes, varactor diodes, or different types of transistors. In this paper varactor diodes were combined with transverse microstrip fed slot antennas to achieve electronic switching of slot antennas. The switching function of the transverse microstrip fed slot antenna was realized by turning the varactor diode on or off. When the diode was with the negative maximum DC bias voltage, the total impedance of the slot antenna was designed to be well matched to the feedline. The signal radiated out efficiently and the slot antenna was switched on. When the diode was with 0 VDC bias, the total impedance of the antenna structure was designed to be mismatched to the feedline. All power was reflected back due to the mismatch and hence the antenna was switched off.
Introduction (2012)

Mentoring has long been a topic of interest, research, and discussion in multiple arenas of practice; businesses, schools, military, churches, to name just a few. While the benefits of mentoring and mentoring relationships are typically agreed upon, there are various specific styles or formats in the way mentoring activities are implemented. The very synergistic nature of mentoring implies that perhaps there is neither one best practice nor one lens with which to examine all of our unique experiences.
<title>Creating a biologically plausible model of recognition which generalizes multidimensional scaling</title> (1999)

We present a method for reconstructing multidimensional scaling (MDS) as a biologically plausible algorithm for storing object data. To do so, we must make modifications in the definitions of stress, and in locating the process. We make these modifications by appealing to physical definitions of stress and deformation. In this system, classical MDS becomes the system in which these are modeled on perfectly elastic deformation, and a variety of systems can be created or trained which are, by contrast, viscoelastic. The resultant model is useful in applications in which the relationship between stress and the underlying metric used for MDS is complicated by local phenomena, or in which these quantities need to be modeled as learned or changing attributes.
Inhibiting Effects of Group 6 Oxo-Anions on the Pitting Corrosion of Tin in Citrate-Chloride Solution (2000)

Abstract The effect of chloride ions on both anodic dissolution and pitting corrosion of tin metal in the aerated equimolar solutions 0.1 M (1 M = 1 mol dm-3) citrate-chlorid-oxo-anions (CrO42-, WO42-, and MoO42-) has been investigated. Different techniques were used, such as potentiodynamic, potentiostatic polarization, electrochemical impedance spectroscopy techniques. These were complemented by surface examination using scanning electron microscopy. Lower current values in the presence of equimolar (0.1 M) citrate-oxo-anions with addition of Cl- in various concentrations were observed, compared with those obtained in the oxo-anion free solutions. Thus, these oxo-anions might create a certain impediment or barrier to the attack of the aggressive Cl- on the metal surface. However, the addition of the studied anions at lower concentrations (10-3 and 10-2 M) in 0.1 mol dm-3 citrate-chloride, enhanced the active metal dissolution and passivity break down of tin. Retardation to a considerable extent was observed, however, at higher concentrations (5×10-2 and 10-1 M). All measurements using the different techniques, under the same conditions, confirmed that the order of reduced aggressiveness of Cl- was CrO42- &gt; WO42- &gt; MoO42-. This indicates that CrO42- remains the best inhibitor to prevent the pitting corrosion, probably through its ability to repair defects in the oxide film.
Negative electron affinity silicon heterojunction photocathodes with alkali antimonide intermediate layers (1992)

In this paper, some new types of p-Si(100) photocathodes with n-K3Sb, n-Na3Sb, and p-Cs3Sb intermediate layers are fabricated. They are the (Si-K3Sb-Cs)-O-Cs and (Si-Na3Sb-Cs)-O-Cs negative electron affinity heterojunction photocathodes, and the (Si-Cs3Sb-Cs)-O-Cs positive electron affinity photocathode. For cathodes with n-K3Sb, n-Na3Sb, and p-Cs3Sb intermediate layers, the maximum photoemission sensitivities attainable are, respectively, 1050, 950, and 150 μA/lm, and the measured minimum work functions of these cathodes are, respectively, 0.9, 1.0, and 0.85 eV. The photoemission stability of the Si photocathode with an alkali antimonide intermediate layer is better than that of the conventional Si-O-Cs and GaAs-O-Cs cathodes. The stability of the cathode is also related to the states of the cesium and oxygen during the activation process and the light illumination condition.
Detection of <i>Pythium ultimum</i> Using Polymerase Chain Reaction with Species-Specific Primers (1997)

This study was conducted to sequence the rDNA internal transcribed spacer (ITS) region of Pythium ultimum and Pythium group HS, design species-specific primers for polymerase chain reaction (PCR), and detect P. ultimum from diseased seedlings using PCR. The sequence of the ITS region of P. ultimum was identical with that of Pythium group HS. The results support the reports that the HS group is an asexual strain of P. ultimum. Using PCR, the primer pair K1+K3, designed on portions of the sequence of the ITS region, amplified isolates of P. ultimum and the HS group but not isolates of 20 other Pythium species. DNA extracts from damped-off seedlings were not amplified, but a 10-fold dilution of the extracts with Tris-EDTA (TE) buffer diluted the inhibitors and allowed PCR amplification. The primer pair used detected P. ultimum from a single diseased seedling.
Fortschritte in der spezifischen Bestimmung der Pankreas-α-Amylase (1988)

The monoclonal antibodies 66C7 and 88E8, both specific for human salivary <x.-amylase, inhibit by their combined synergistic action human salivary ,-amylase by more than 97%. Pancreatic OL-amylase is not influenced by the two antibodies. Two reagents using the two antibodies for pancreatic oL-amylase determination are described. The Substrates for the activity determination are p-nitrophenyl-maltoheptaoside and the ethylidene protected analogue. The direct determination of human pancreatic ot-amylase without calculation from total and residual activity after partial Inhibition or by use of various Separation Steps allows that the parameter pancreas a-amylase will in future replace the total L-amylse determination. This is a further Step in the differential diagnosis of pancreatic diseases.

Coherent anti-Stokes Raman scattering in isolated air-guided modes of a hollow-core photonic-crystal fiber (2004)

Hollow-core photonic-crystal fibers are shown to offer the unique possibility of coherent excitation and probing of Raman-active vibrations in molecules by isolated air-guided modes of electromagnetic radiation. A $3\text{\ensuremath{-}}\mathrm{cm}$ section of a hollow photonic-crystal fiber is used to prepare isolated air-guided modes of pump and probe fields for a coherent excitation of $2331{\text{\ensuremath{-}}\mathrm{cm}}^{\ensuremath{-}1}$ $Q$-branch vibrations of molecular nitrogen in the gas filling the fiber core, enhancing coherent anti-Stokes Raman scattering through these vibrations by a factor of 15 relative to the regime of tight focusing.
