Synthesis of a Water-soluble Metal&#8211;Organic Complex Array (2016)

We demonstrate a method for the synthesis of a water-soluble multimetallic peptidic array containing a predetermined sequence of metal centers such as Ru(II), Pt(II), and Rh(III). The compound, named as a water-soluble metal-organic complex array (WSMOCA), is obtained through 1) the conventional solution-chemistry-based preparation of the corresponding metal complex monomers having a 9-fluorenylmethyloxycarbonyl (Fmoc)-protected amino acid moiety and 2) their sequential coupling together with other water-soluble organic building units on the surface-functionalized polymeric resin by following the procedures originally developed for the solid-phase synthesis of polypeptides, with proper modifications. Traces of reactions determined by mass spectrometric analysis at the representative coupling steps in stage 2 confirm the selective construction of a predetermined sequence of metal centers along with the peptide backbone. The WSMOCA cleaved from the resin at the end of stage 2 has a certain level of solubility in aqueous media dependent on the pH value and/or salt content, which is useful for the purification of the compound.
NERVA-Derived Concept for a Bimodal Nuclear Thermal Rocket (2005)

The Nuclear Thermal Rocket is an enabling technology for human exploration missions. The “bimodal” NTR (BNTR) provides a novel approach to meeting both propulsion and power requirements of future manned and robotic missions. The purpose of this study was to evaluate tie‐tube cooling configurations, NTR performance, Brayton cycle performance, and LOX‐Augmented NTR (LANTR) feasibility to arrive at a point of departure BNTR configuration for subsequent system definition.

Polar-Embedded and Polar-Endcapped Stationary Phases for LC (2010)

Polar-embedded and polar-endcapped phases have become widespread over the past decade. When compared to classical alkylsilicas, they offer an alternative selectivity profile, increased stability in highly aqueous mobile phases, and improved peak shape for basic analytes. This mini-review summarizes current knowledge and applications of these phases, including the recent development of a series of N-methylamide embedded phases, prepared using supercritical carbon dioxide.
Liquid Crystal Frequency Tunable Terahertz Metamaterial Absorber (2016)

Here, we theoretically and experimentally realize a terahertz (THz) perfect metamaterial absorber with an actively tunable frequency response. The structure is made of a complementary frequency selective surface (CFSS) and a metal backplane where the subwavelength space between them is filled with liquid crystal. By applying a voltage between CFSS and metal backplane a resonance frequency shifts about 4.5 GHz at 0.567 THz is obtained while the absorbance maintains at %90.
Inductance Calculations of Variable Pitch Helical Inductors (2015)

Abstract : A technique has been developed to calculate the inductance of variable pitch helicoil inductors of rectangular cross section that use a coaxial return feed along the center of the coil. The calculations discretize the coil into a series of rings of current that take into account the diffusion of current or skin depth. The inductance is a combination of each ring???s self-inductance and the mutual inductances of all the current rings. To validate the technique, a series of coils were machined from aluminum tubes and then their inductances were measured at 3 different frequencies. The calculated inductances are compared to the measured inductances.

Progresses of Remediation Techniques for Polluted Sediment (2002)

Remediation techniques for polluted sediment are discussed in this paper. The remediation techniques contain physical treatment, such as dredging, capping, and bioremediation. Physical treatment can control contaminated sediment relatively easily, but cost too much, while bioremediation is just reversed. To access legal criterion and reduce cost, various techniques must be applied to treat the contaminated sediments according to their properties. Break down products were suggested to be reused after biodegradation.
Development of Operand Desorption Gas Analysis System (2019)

is a member of the Nanofabrication Platform Consortium in the Nanotechnology Platform Japan. Our laboratory features the desorption gas analysis of materials and devices based on the original vacuum technology in addition to the nanofabrication. In this paper, an operand desorption gas analysis system (apparatus for dynamic thermal desorption spectroscopy), which is one of our gas analysis systems, is explained. The advantage of this system is that it enables a desorption gas analysis of an operating device under an approximately atmospheric pressure (0.1 to 0.2 MPa) using gas chromatography/mass spectrometry, in contrast to a sample placed in a vacuum in a conventional apparatus for thermal desorption spectroscopy. Moreover, two measurement examples (DC electric motor and solar cell) using this operand gas analysis system were described. In the DC motor, the main desorbed gas from the motor behaved similarly to the motor electric power with the occurrence of failure or stop caused by heating. In the solar cell, from the comparison of the temperature dependence between the open circuit voltage and the main desorbed gases from the solar cell, the temperature durability of the sealing part is confirmed to be related to the electron generation efficiency.

To reduce the analog area, a balanced 3-phase analog system is adopted and the functions of analog baseband filters and VGAs are moved to digital domain. The downconverter and ADC are directly connected and they occupy 0.28 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Realizing enterprise integration patterns in WebSphere (2005)

Over the last few years, patterns became focus of many activities in both, software development and research. Because of the financial significance of enterprise application integration (EAI) technologies corresponding patterns in this area are especially important and, thus, found a lot of interest. Even a standard textbook has been well-established in this space ("Enterprise Integration Patterns"). People are asking for guidelines about how to use the patterns from this textbook in their environment. A Whitepaper of Hohpe provides a sample integration scenario together with guidelines of how to implement this integration scenario based on a subset of the patterns in the BizTalk Server 2004 environment. In this document, we use the same scenario and the same patterns as in this Whitepapper and show how to implement them in WebSphere.
Glutathione-S-transferase and tyrosine hydroxylase activity in human adrenal medulla. Differences between fetal and adult tissue (2005)

Con el objetivo de caracterizar la glándula adrenal humana en estado fetal (10 a 12 semanas) y adulta (post-morten) se determinaron las actividades específicas de la enzimas glutatión-S-transferasa (GST) y tirosina hidroxilasa (TH), así como las de las catecolaminas (CA): adrenalina (A); noradrenalina (NA) y dopamina (DA), utilizando Cromatografía Líquida de Alta Resolución con detecci ón electroquímica (HPLC-DE). La GST fue determinada utilizando 1-cloro-2,4- dinitrobenzeno como substrato electrofílico y la actividad TH fue determinada por medición de la L-DOPA formada a partir de la L-tirosina utilizando un HPLCDE. Los resultados indican que la NA fue la principal CA presente en el período fetal estudiado. Una disminución en la actividad de NA acompañado por un ligero incremento en la de A fue detectada con el aumento de la edad fetal. En el tejido adulto la A fue la principal CA y presentó una cantidad de DA (0,046 % del total de CA) 35 veces menor que en el tejido fetal (1,60 %). La actividad específica de la TH presentó diferencias al ser comparada con el tejido fetal y fue significativamente mayor (p &lt; 0,001) en el tejido fetal. La actividad de la GST fue también significativamente superior (p &lt; 0,001) en el tejido adulto cuando se comparó con el fetal. Los resultados indican un relativamente pobre aporte de la células fetales, en cuanto a su actividad TH. Los cambios detectados en la actividad enzimática específica de la GST entre el tejido adulto y fetal pueden revelar una diferencia en la capacidad entre estos tejidos para metabolizar xenobioticos y toxinas endógenas. Estos resultados pudieran contribuir a la explicación de los resultados del implante de células catecolaminérgicas en la enfermedad de Parkinson.
Failure of acetabular autogenous grafts in total hip arthroplasty. Increasing incidence (1990)

We reported previously on the application of an autogenous femoral-head graft to the acetabulum during total hip arthroplasty for compensation of marked osseous deficiency in patients who had arthritis secondary to severe congenital dysplasia or dislocation of the hip. An average of seven years postoperatively, the graft seemed to have been a successful adjunct to the arthroplasty. Five years later, to assess our long-term results, we reviewed the findings in the same forty-six hips (thirty-seven patients) that we had studied previously. An average of 11.8 years after the total replacement and use of the autogenous femoral-head graft, nine hips (20 per cent) needed a second operation because the acetabular fixation had failed. Two had had a resection arthroplasty and seven, a complex revision. In one additional hip, a resection arthroplasty was done for infection that had developed after operative reattachment of the greater trochanter. In twelve of the remaining thirty-six hips, there was definite radiographic evidence of acetabular loosening. Thus, the total incidence of loosening of the acetabular component was 46 per cent (twenty-one hips). The average time from the index operation to the first definite radiographic evidence that the fixation had failed was 6.4 years (range, 2.9 to 12.7 years). While we recognize that application of a bulk autogenous graft to the acetabulum is useful when the acetabular bone stock is extremely deficient, we no longer recommend the use of bulk corticocancellous autogenous grafts in other situations.
Stopping Rules for Bag-of-Words Image Search and Its Application in Appearance-Based Localization (2013)

We propose a technique to improve the search efficiency of the bag-of-words (BoW) method for image retrieval. We introduce a notion of difficulty for the image matching problems and propose methods that reduce the amount of computations required for the feature vector-quantization task in BoW by exploiting the fact that easier queries need less computational resources. Measuring the difficulty of a query and stopping the search accordingly is formulated as a stopping problem. We introduce stopping rules that terminate the image search depending on the difficulty of each query, thereby significantly reducing the computational cost. Our experimental results show the effectiveness of our approach when it is applied to appearance-based localization problem.
Absolute calibration of a hydrogen discharge lamp in the vacuum ultraviolet (1975)

A low-pressure hydrogen discharge lamp was calibrated for radiant intensity in the vacuum ultraviolet spectral region on an absolute basis and was employed as a laboratory standard source in spectrograph calibrations. This calibration was accomplished through the use of a standard photodiode detector obtained from the National Bureau of Standards together with onsite measurements of spectral properties of optical components used. The stability of the light source for use in the calibration of vacuum ultraviolet spectrographs and optical systems was investigated and found to be amenable to laboratory applications. The lamp was studied for a range of operating parameters; the results indicate that with appropriate peripheral instrumentation, the light source can be used as a secondary laboratory standard source when operated under preset controlled conditions. Absolute intensity measurements were recorded for the wavelengths 127.7, 158.0, 177.5, and 195.0 nm for a time period of over 1 month, and the measurements were found to be repeatable to within 11 percent.
Behaviour of vanadia-catalyzed SO2 oxidation in the presence of inert, diluent gases (1976)

Observations on the effect of diluent gas on the rate of oxidation of SO 2 over a commercial vanadia catalyst reported by Yeramian etal. in a 1970 paper in this journal have been extended in this study.A pronounced increase in rate is observed when inert diluents krypton and C 4 F 8 are substituted for helium. The influence of other diluents was less marked. The increase in rate bas been found to depend upon the partial pressure of the diluent and to be extremely sensitive to the ratios of the reactants.
Control analysis of an ejector based fuel cell anode recirculation system (2006)

An ejector based recirculation system is incorporated on the anode side of the fuel cell to address anode flooding. The objective of the recirculation system is to regulate anode humidity with recirculating flow, while safeguarding the membrane and supporting the electric load. These objectives can be achieved by a control system that uses two actuators, namely the fuel supplied from the fuel source and a back pressure valve placed in the recirculation path. For these actuators, the control analysis presented in this paper identifies anode pressure, along with either return manifold pressure or recirculation flow rate, as variables to be tracked in order to facilitate meeting of the control objectives, while assuring internal stability. Feedback regulation of these variables with a minimum number of pressure sensors is addressed by identifying appropriate sensor locations. The sensor selection and corresponding observer design for the system are treated from the points of view of the observability requirements and robustness to sensor noise. The performance of various sensor combinations shows that measurement of anode pressure is adequate for a full order observer based state feedback controller.
Catalytic Transfer Hydrogenation of Azo Compounds to Hydrazo Compounds Using Inexpensive Commercial Zinc Dust and Hydrazinium Monoformate (2003)

Azo compounds are conveniently reduced to hydrazo compounds by using commercial zinc dust and hydrazinium monoformate at room temperature. Many reducible and hydrogenolysable groups like OCH3, OC2H5, OH, COOH, CH3, SO3Na and halogens are tolerated. The reduction is fast, clean, high‐yielding and inexpensive.

Mixed Gonadal Dysgenesis: Case Reports and a Review of 65 Japanese Cases (1991)

Four cases of mixed gonadal dysgenesis encountered in our institute are described here, and 65 cases of mixed gonadal dysgenesis in the Japanese literature, including our cases, are reviewed. Of the four cases reported here, three had a chromosomal structure of 46,XY and one of 45,XO/46,XYq-. A chromosomal structure of 45,XO/46,XY accounts for 35% of all cases of mixed gonadal dysgenesis reported in the Japanese literature, 46,XY for 31%, and other types for 24%. Two of our cases (50%) also had a gonadal tumor. The overall incidence of gonadal tumor occurring after onset of puberty and reported in the Japanese literature is 17%.
Structured Neural Summarization (2018)

Summarization of long sequences into a concise statement is a core problem in natural language processing, requiring non-trivial understanding of the input. Based on the promising results of graph neural networks on highly structured data, we develop a framework to extend existing sequence encoders with a graph component that can reason about long-distance relationships in weakly structured data such as text. In an extensive evaluation, we show that the resulting hybrid sequence-graph models outperform both pure sequence models as well as pure graph models on a range of summarization tasks.
Analytical Characterization of the Performance of Steel Heavy Clip Angle Connections (2013)

Based on some of experimental results for components and full-scale connections, this paper investigates the strength, stiffness and ductility behavior of heavy clip angle connection components subjected to static loading. The results of tests on heavy clip angle connection (t=25mm) are described first, and then a methodology to generate the response of the clip angle connection using nonlinear finite element models (FE) is presented. Extensive experience with 3D numerous models is discussed, including the effect of boundary conditions, introduction of the pretension force into the bolts, and effects of small changes in geometry on the deformation capacity of the angles. Possible strategies for the extension of this modeling approach to cyclic loads are also described.
Rituximab blocks binding of radiolabeled anti-CD20 antibodies (Ab) but not radiolabeled anti-CD45 Ab (2008)

Rituximab therapy is associated with a long in vivo persistence, yet little is known about the effect of circulating rituximab on B-cell non-Hodgkin lymphoma (B-NHL) targeting by the other available anti-CD20 monoclonal antibodies (MoAbs) (131)iodine-tositumomab and (90)yttrium-ibritumomab tiuxetan. Therefore we assessed the impact of preexisting rituximab on the binding and efficacy of second anti-CD20 MoAbs to B-NHL and determined whether targeting an alternative lymphoma-associated antigen, CD45, could circumvent this effect. We demonstrated that rituximab concentrations as low as 5 microg/mL nearly completely blocked the binding of a second anti-CD20 MoAbs (P < .001), but had no impact on CD45 targeting (P = .89). Serum from patients with distant exposures to rituximab also blocked binding of anti-CD20 MoAbs to patient-derived rituximab-naive B-NHL at concentrations at low as 7 microg/mL, but did not affect CD45 ligation. A mouse xenograft model (Granta, FL-18, Ramos cell lines) showed that rituximab pretreatment significantly reduced B-NHL targeting and tumor control by CD20-directed radioimmunotherapy (RIT), but had no impact on targeting CD45. These findings suggest that circulating rituximab impairs the clinical efficacy of CD20-directed RIT, imply that novel anti-CD20 MoAbs could also face this same limitation, and indicate that CD45 may represent an alternative target for RIT in B-NHL.
Differential activation of promutagens by alloenzymes of human sulfotransferase 1A2 expressed in Salmonella typhimurium (2002)

Various enzymatically formed sulfuric acid esters are chemically reactive and mutagenic. This metabolic activation pathway is not detected in standard in-vitro mutagenicity test systems. We describe the construction of Salmonella typhimurium TA1538-derived strains expressing alloenzymes *1, *2, *3, *5, *6 of human sulfotransferase 1A2 (SULT1A2). The reference compounds, 1-hydroxymethylpyrene (1-HMP), N-hydroxy-2-acetylaminofluorene (OH-AAF) and 2-hydroxylamino-5-phenylpyridine (OH-APP), were activated to mutagens in these strains. Their activity differed 7- to 16-fold between strains expressing various alloenzymes. It was strongest and weakest in the strains expressing the common alloenzymes, *1 and *2, respectively. The SULT1A2 protein expression levels, and the V(max) and K(m) values with the reference substrate 4-nitrophenol, varied 2.5-, 4-, and 110-fold, respectively, in cytosolic preparations from strains TA1538-SULT1A2*1 and *2. Strains with varying protein levels were constructed via insertion of silent mutations in the 5'-part of the cDNA. TA1538-SULT1A2*1Z and TA1538-SULT1A2*2Y showed equal expression levels of alloenzymes *1 and *2, respectively, which were 3 times above those of TA1538-SULT1A2*1. The mutagenicity of OH-AAF and OH-APP was unchanged in strain TA1538-SULT1A2*1Z versus *1, and moderately increased in TA1538-SULT1A2*2Y versus *2. The influence of the protein level was stronger with 1-HMP. Nevertheless, mutagenic activity of 1-HMP was still 11 times higher in TA1538-SULT1A2*1Z than in TA1538-SULT1A2*2Y. Thus, differences in the properties between alloenzymes can lead to differences in the activation of promutagens. The model compounds were also tested in strains expressing the other ten human SULTs identified. Whereas OH-AAF and OH-APP showed the highest mutagenic activities in strains expressing SULT1A2, 1-HMP was more potent in strains expressing other SULT forms. With the limitation that little is known about the tissue distribution and regulation of SULT1A2, the findings suggest that its polymorphism may affect the individual susceptibility towards procarcinogens, in particular certain aromatic amines and amides.
