Study on the K-factor function in the lightning impulse test for UHV-class electric power equipment (2012)

Ultra high voltage (UHV) systems are increasingly being planned and constructed, hence studies are promoted on the standard for high-voltage test techniques for UHV-class equipment. For the lightning impulse voltage test, a study is being conducted on the application of a method of evaluating the test waveform through conversion using the test voltage function (K-factor function) that was adopted in IEC 60060-1. The existing K-factor function was established based on the experimental results for more compact models, as compared with the insulating structure of UHV-class equipment, mainly with a breakdown voltage of about 100 kV. To determine whether this K-factor function can also be used for the test of UHV-class equipment, the experimental results for large-sized models were needed. To address this issue, the authors experimentally obtained K-factor values using the largest possible model (UHV model) assuming UHV-class equipment in the previous studies. In the present paper, a study was conducted on a new K-factor function based on these experimental results using UHV models. Initially in the study, several ideas for the K-factor function were shown and applied to various waveforms to clarify their advantages and disadvantages. Subsequently, in addition to these results, a study was conducted on a K-factor function suitable for UHV-class equipment with considering the actual UHV facilities. Consequently, it was concluded that the form of the function should be the same as that of the existing one but that it would be reasonable to adopt a relatively lower K-factor function for UHV-class equipment by revising the constant.
Induction of Viral Interference in Mice by Aerosols of Inactivated Influenza Virus. (1963)

Inactivated influenza viruses administered to mice intranasally or by aerosol induced transient heterologous immunity to infective influenza viruses. This immunity was reflected by reduction of pulmonary viral titers and by a reduced occurrence of gross lesions. This effect is considered to be an example of viral interference in that it required time to develop and persisted for at least 3 days; and because protective activity of inactivated viruses in mice could be correlated with interfering activity in the chick embryo. Interference modified but did not completely inhibit infection, and strain specific immunity of lessened degree developed to the challenge virus following the modified infection.
STUDIES ON THE CONTENT AND ORGANIZATION OF THE RESPIRATORY ENZYMES OF MITOCHONDRIA (1961)

(1) The mathematical calculations relating spectrophotometric data with the data of Allard et al. (4, 5) on mitochondrial counts, is presented. Such a calculation indicates that an "average mitochondrion" from rat liver would contain about 17,000 molecules of each cytochrome pigment. (2) Hematocrit determinations relating respiratory pigment content for mitochondria isolated from a variety of tissues have been presented, showing a fivefold variability depending upon the source of the mitochondria. (3) Speculations on the organization of the respiratory enzymes associated with the membrane structure of the mitochondria are discussed.
Molecular Engineering of Liquid Crystal Polymers by Living Polymerization. VIII. Influence of Molecular Weight on the Phase Behavior of Poly {ω-[(4-Cyano-4′-biphenyl)-oxy]alkyl Vinyl Ether}s with Ethyl, Propyl, and Butyl Alkyl Groups (1991)

Abstract The synthesis and living cationic polymerization of 2-[4-cyano-4′-biphenyl)oxy]ethyl vinyl ether (6–2), 3-[4-cyano-4′-biphenyl)oxy]-propyl vinyl ether (6-3), and 4-[4-cyano-4′-biphenyl)oxy]butyl vinyl ether (6-4) are described. The mesomorphic behaviors of poly(6–2), poly(6-3), and poly(6-4) with different degrees of polymerization and narrow molecular weight distributions were compared to those of 6–2, 6–3, and 6–4 and of 2-[(4-cyano-4′-biphenyl)oxy]ethyl ethyl ether (8–2), 3-[(4-cyano-4′-biphenyl)oxy]propyl ethyl ether (8–3), and 4-[4-cyano-4′-biphenyl)oxy]butyl ethyl ether (8–4) which are model compounds of the monomeric structural units of poly(6–2), poly(6–3), and poly(6–4). In the first heating scan, all three polymers exhibit an x (unidentified) mesophase which overlaps the glass transition temperature, and an enantiotropic nematic mesophase. In the second and subsequent heating and cooling scans, poly(6–3) and poly(6–4) display only the enantiotropic nematic mesophase. Both in the first and subsequent scans, only poly(6–2) with degrees of polymerization lower than 4 exhibits an enantiotropic nematic mesophase.
Core-Based Testing of Embedded Mixed-Signal Modules in a SoC (2009)

This article describes test development for embedded mixed-signal and RF modules in core-based design. The test development approach is fully automated and encompasses a DFT architecture that supports an arbitrary test method. Fully compliant with existing IEEE test standards, the proposed approach has been used for test development and characterization of mixed-signal cores in several industrial products. Two SoC examples emphasize its benefits and performance.
Carbon-11-methionine and PET is an effective method to image head and neck cancer. (1992)

Methionine metabolism is altered in cancer, and methionine labeled with 11C has been successfully used for imaging of brain, lung, and breast cancer and lymphoma. Uptake of L-[methyl-11C]methionine (11C-methionine) in head and neck cancer of 23 patients was studied with PET. Accumulation of 11C-methionine in the tumors was assessed by two different methods: the influx constant, Ki, and the standardized uptake value (SUV). All 23 cancers accumulated 11C-methionine. The mean Ki was 0.147 +/- 0.070 min-1 and the mean SUV 8.5 +/- 3.5. There was a strong correlation between the two measures of tumor uptake (r = 0.92, p less than 0.0001). There was no correlation between the uptake of 11C-methionine and the histological grade of cancer. Head and neck cancer can thus be effectively imaged with 11C-methionine. Carbon-11-methionine PET imaging may be useful in delineating tumors for therapy planning.
Gas Chromatography—Matrix Isolation Infrared Spectroscopy—Mass Spectrometry for Analysis of Thermally Generated Aroma Compounds (1989)

An integrated GC/IR/MS instrument is a powerful tool for rapid identification of thermally generated aroma compounds. Fourier transform infrared spectroscopy (GC/IR) provides a complementary technique to mass spectrometry (MS) for the characterization of volatile flavor components in complex mixtures. Recent improvements in GC/IR instruments have made it possible to construct an integrated GC/IR/MS system in which the sensitivity of the two spectroscopic detectors is roughly equal. The combined system offers direct correlation of IR and MS chromatograms, functional group analysis, substantial time savings, and the potential for an expert systems approach to identification of flavor components. Performance of the technique is illustrated with applications to the analysis of volatile flavor components in charbroiled chicken.
The Human COL11A2 Gene Structure Indicates that the Gene Has Not Evolved with the Genes for the Major Fibrillar Collagens (1995)

The human COL11A2 gene was analyzed from two overlapping cosmid clones that were previously isolated in the course of searching the human major histocompatibility region (Janatipour, M., Naumov, Y., Ando, A., Sugimura, K., Okamoto, N., Tsuji, K., Abe, K., and Inoko, H. (1992) Immunogenetics 35, 272-278). Nucleotide sequencing defined over 28,000 base pairs of the gene. It was shown to contain 66 exons. As with most genes for fibrillar collagens, the first intron was among the largest, and the introns at the 5'-end of the gene were in general larger than the introns at the 3'-end. Analysis of the exons coding for the major triple helical domain indicated that the gene structure had not evolved with the genes for the major fibrillar collagens in that there were marked differences in the number of exons, the exon sizes, and codon usage. The gene was located close to the gene for the retinoic X receptor beta in a head-to-tail arrangement similar to that previously seen with the two mouse genes (P. Vandenberg and D. J. Prockop, submitted for publication). Also, there was marked interspecies homology in the intergenic sequences. The amino acid sequences and the pattern of charged amino acids in the major triple helix of the alpha 2(XI) chain suggested that the chain can be incorporated into the same molecule as alpha 1(XI) and alpha 1(V) chains but not into the same molecule as the alpha 3(XI)/alpha 1(II) chain. The structure of the carboxyl-terminal propeptide was similar to the carboxyl-terminal propeptides of the pro alpha 1(XI) chain and pro alpha chains of other fibrillar collagens, but it was shorter because of internal deletions of about 30 amino acids.
Containment units (2002)

Software is increasingly expected to run in a variety of environments. The environments themselves are often dynamically changing when using mobile computers or embedded systems, for example. Network bandwidth, available power, or other physical conditions may change, necessitating the use of alternative algorithms within the software, and changing resource mixes to support the software. We present Containment Units as a software architecture useful for recognizing environmental changes and dynamically reconfiguring software and resource allocations to adapt to those changes. We present examples of Containment Units used within robotics along with the results of actual executions, and the application of static analysis to obtain assurances that those Containment Units can be expected to demonstrate the robustness for which they were designed.
Comparison of ruthenium(ii) and cyclometalated iridium(iii) azacrown ether phenanthroline hybrids for the detection of metal cations by electrochemiluminescence (2010)

Two azacrown ether appended iridium(III) complexes, 1 and 3, are described as probes for metal cations operating on oxidative-reduction electrochemiluminescence (ECL) with tri-n-propylamine as coreactant in acetonitrile. Complexes 1 and 3 exhibit a notable ECL sensing for Ba(2+) and Ag(+), respectively, through a 9-fold emission intensity enhancement and an unprecedented λmax(em) red shift. In contrast, the structurally analogous azacrown ether appended ruthenium(II) complexes 2 and 4 only display insignificant ECL changes and no wavelength shift upon addition of the same metal ions. The key to understand this disparity is to appreciate that the azacrown ether phenanthroline ligand, responsible for metal uptake, represents the LUMO in iridium(III) complexes but is part of the HOMO for the ruthenium analogs. As a consequence, the electron transfer equilibria of the oxidative-reduction ECL process lead to a preferential formation of the metal free, excited ruthenium systems 2* and 4*. In contrast, the iridium complexes 1 and 3 remain coordinated to metal ions in the emitting state, as the oxidation involves the iridium phenylquinoline part, which is not invoked in cation binding.
Weakly Supervised Approach to Defect Detection in Concrete Structures Using Hammering Test (2019)

The need to inspect concrete social infrastructures has put considerable attention on the automation of traditional methods such as the hammering test. In the past, supervised and unsupervised methods have been proposed for this task. However, they either require training data, and there heavy human involvement or additional sensors other than a microphone. In the present study, a novel approach to automation of the hammering test, using only a microphone and with only minimal human user involvement is proposed. The human user is asked for a couple of audio samples if they are similar or not and the audio feature space is shaped according to those answers. Experiment conducted using a concrete test block shows promising results obtained by the proposed method.

A Mechanistic Integrated Geochemical and Chemical Flooding Tool for Alkaline/Surfactant/Polymer Floods (2014)

Abstract Mechanistic simulation of alkaline/surfactant/polymer (ASP) flooding considers chemical reactions between the alkali and the oil to form in-situ soap and reactions between the alkali and the minerals and brine. A comprehensive mechanistic modeling of such process remains a challenge, mainly due to the complicated ASP phase behavior and the complexity of geochemical reactions that occur in the reservoir. Due to the lack of the microemulsion phase and/or lack of reactions that may lead to the consumption of alkali and resulting lag in the pH, a simplified ASP phase behavior is often used. UTCHEM-IPhreeqc, a previously developed robust, accurate, and flexible integrated tool at the University of Texas at Austin (UT), is further expanded to mechanistically model ASP floods. UTCHEM has a comprehensive three-phase (water, oil, microemulsion) phase behavior model for the mixture of surfactant and soap as a function of salinity, temperature, and co-solvent concentration. IPhreeqc, a state-of-the-art geochemical package of the United States Geological Survey (USGS), handles the geochemical reactions involved between crude oil, rock, and brine. Through this integrated tool, we are able to simulate homogeneous and heterogeneous (mineral dissolution/precipitation), irreversible, surface complexation, and ion-exchange reactions under non-isothermal, non-isobaric, and both local-equilibrium and kinetic conditions. IPhreeqc has rich databases of chemical species and also the flexibility to define the alkali reactions required for the ASP modeling. Hence, to the best of our knowledge, for the first time, the important aspects of ASP flooding are considered. The expanded integrated tool, UTCHEM-IPhreeqc, is then used to match three different reaction-related chemical flooding processes: ASP flooding in an acidic active crude oil, ASP flooding in a non-acidic crude oil, and alkaline/co-solvent/polymer (ACP) flooding.
Ca2+ differentially regulates the ligand-affinity states of type 1 and type 3 inositol 1,4,5-trisphosphate receptors (1997)

To elucidate the functional difference between type 1 and type 3 Ins(1,4,5)P3 receptors [Ins(1,4,5)P3R1 and Ins(1,4,5)P3R3 respectively] we studied the effect of Ca2+ on the ligand-binding properties of both Ins(1,4,5)P3R types. We expressed full-length human Ins(1,4,5)P3R1 and Ins(1,4,5)P3R3 from cDNA species in insect ovary Sf9 cells, and the membrane fractions were used for Ins(1,4,5)P3-binding assays. The binding of Ins(1,4,5)P3 to Ins(1,4,5)P3R1 and Ins(1,4,5)P3R3 was differentially regulated by Ca2+. With increasing concentrations of free Ca2+ ([Ca2+]), Ins(1,4,5)P3 binding to Ins(1,4,5)P2R1 decreased, whereas that to Ins(1,4,5)P3R3 increased. Alteration of Ins(1,4,5)P3 binding to Ins(1,4,5)P3R1 was observed at [Ca2+] ranging from less than 1 nM to more than 10 microM. The EC50 of Ins(1,4,5)P3 binding was 100 nM Ca2+ for Ins(1,4,5)P3R1. In contrast, Ins(1,4,5)P3 binding to Ins(1,4,5)P3R3 was changed at high [Ca2+] with an EC50 value of 872 nM, and steeply between 100 nM and 10 microM. These Ca2+-dependent alterations of Ins(1,4,5)P3 binding to both Ins(1,4,5)P3R types were reversible. Scatchard analyses revealed that Ca2+ changed the affinity of both Ins(1,4,5)P3R types but not the total number of Ins(1,4,5)P3-binding sites. The Kd values of Ins(1,4,5)P3R1 for Ins(1,4,5)P3 were 78.5 nM with 3 nM free Ca2+, and 312 nM with 1.4 microM free Ca2+. In contrast, Ins(1,4,5)P3R3 exhibited an affinity for Ins(1,4,5)P3 with Kd values of 116 nM with 3 nM free Ca2+, and 62.2 nM with 1.4 microM free Ca2+. These results indicate that (1) both Ins(1,4,5)P3R1 and Ins(1,4,5)P3R3 have at least two affinity states, (2) Ca2+ regulates interconversions between these states, and (3) Ca2+ regulates the binding of Ins(1,4,5)P3 to Ins(1,4,5)P3R1 and Ins(1,4,5)P3R3 in opposite manners.
High Concentration but Low Activity of Hepatocyte Growth Factor in Periodontitis (2013)

Higher circulatory HGF levels indicate a systemic effect of periodontitis. However, the HGF biologic activity at local inflammation sites was reduced, and this effect was associated with the amount of periodontal bacteria. Loss of function of healing factors may be an important mechanism in degenerative processes in periodontally susceptible individuals.
Intermedin/adrenomedullin‐2 (IMD/AM2) relaxes rat pulmonary arterial rings via protein kinase G (PKG) and BKCa channel dependent pathway: The effect of chronic hypoxia induced pulmonary hypertension (2008)

Our previous results showed that when rat pulmonary arterial (PA) rings were precontracted with U‐46619 IMD relaxes PA rings in a nitric oxide and endothelial dependent manner. In this study the pulmonary vasorelaxant response (PVR) to IMD in PA was inhibited by cholera toxin, Rp‐8‐Br‐PET‐cGMPs and iberitoksin whereas rolipram, KT5720 and apamin were without effect. PVR to IMD was potentialized in the presence of sildenafile. In PA rings isolated from rats with pulmonary hypertension induced by chronic hypoxia (PHCH), PVR to both IMD and ACh response were diminished. In contrast, in the isolated, buffer‐perfused rat lungs with PHCH, the pulmonary vasodilator responses to IMD and ACh were not altered. In PA rings from rats with PHCH, the PVR to NS1619 decreased when compared to control rats. The present data suggest that cGMP‐induced PKG activation and promotion of hyperpolarization through BKCa is the major pathway for rIMD induced vasorelaxation in PA rings. CH may induce downregulation of BKCa channels in pulmonary arterial conductance segments whereas pulmonary resistance arterial segments may not be susceptible to similar changes by PHCH, it is possible other mechanisms such as selective upregulation of eNOS or downregulation in phosphodiesterase activity in response to CH in resistance arteries may explain the difference in vascular responsiveness.
Phase I trial and pharmacokinetics of fenretinide in children with neuroblastoma. (2003)

In children, 4HPR administration up to 4000 mg/m(2)/day over 28 days, followed by a 7-day interruption, results in manageable toxicity and in drug plasma concentrations comparable with those that induce apoptosis in neuroblastoma cell lines.
Video identification using video tomography (2009)

Video identification or copy detection is a challenging problem and is becoming increasingly important with the growing popularity of online video services. The problem addressed in this paper is the identification of a given video clip in a given set of videos. For a given query video, the system returns all the instance of the video in the data set. This identification system uses video signatures based on video tomography. A robust and low complexity video signature is designed. The signatures are generated for video shots and not individual frames. This results in a compact signature of 64 bytes per video segment/ shot. The signatures are matched using simple Euclidean distance metric. Both signature generation and matching have a very low complexity. The system was evaluated using the dataset from video copy detection evaluations organized at the CIVR 2007. The results show that the proposed signatures outperform the results reported in the CIVR competition. The results also show that the signature is robust to common video transformations.
