<title>Interworking architecture for seamless service utilization between the TINA-based public network and the Internet</title> (1998)

In this paper, we considered two networks which are the next-generation public network and the Internet, as the future information network infrastructure. These two networks had originally been developed independently, and now they both have several services for users to be able to utilize services on the Internet environment from the public network environment, and especially to utilize services on the public network from the Internet environment. This will have a bad influence on the future multimedia network society. Consequently, we adopted TINA, and proposed the interworking architecture for seamless service utilization between the two networks. Because these two networks have different characters, we introduce an IWU as a gateway node to realize seamless interworking. The IWU is the gateway for both application level and transport level. More over, considering to utilize public network's services from the Internet after a user moves to the place where s/he can only use the Internet environment, the kind of terminals/operating-system s/he would use is indefinite factor. However, it is obviously desirable to be able to utilize the public network's services with any terminal/operating-system. Therefore we also proposed and implemented the platform named PLUS-TINA. The PLUS-TINA is constructed with Java language so as to insure its portability.

Effects of Fluorescent Reporter Group Structure on the Dynamics Surrounding Cysteine-26 in Spinach Calmodulin: A Model Biorecognition Element (1998)

Conformational changes associated with the Ca 2+ -dependent activation of spinach calmodulin (CaM) have been assessed in aqueous solution by using steady-state and frequency-domain fluorescence spectroscopy of acrylodan-, fluorescein-, and tetramethylrhodamine-labeled CaM. Spinach CaM was site-selectively labeled at cysteine-26 so we could study the dynamics at a well-defined location within the protein. By using multiple fluorophores attached to the same site, we determined the Ca 2+ -dependent changes in the CaM global rotational dynamics, and also determined how the local fluorophore dynamics were affected by the fluorophore polarity, size, and charge. Upon binding Ca 2+ at pH 7.00, spinach CaM changes its conformation by exposing the acrylodan fluorescent reporter group to a more dipolar environment. There is also a concomitant increase in the fluorescein pKa when Ca 2+ binds to CaM. The global motions of spinach CaM are described by rotational reorientation times of 8.4 and 10.5 ns for the apo- and Ca 2+ -saturated CaM at 23 °C. In light of all the available data in the literature on CaM, these results are consistent with a small expansion of the CaM globular domains, a bending and/or rotation of the central peptide chain that connects the globular domains that host the four Ca 2+ binding sites (two per domain) in such a way that residues 27 and 139 are brought closer to one another, and/or a difference in the degree of hydration between the apo- and Ca 2+ -saturated CaM.
<title>Quantizer characteristics important for quantization index modulation</title> (2001)

Quantization Index Modulation (QIM) has been shown to be a promising method of digital watermarking. It has recently been argued that a version of QIM can provide the best information embedding performance possible in an information theoretic sense. This performance can be demonstrated via random coding using a sequence of vector quantizers of increasing block length, with both channel capacity and optimal rate-distortion performance being reached in the limit of infinite quantizer block length. For QIM, the rate-distortion performance of the component quantizers is unimportant. Because the quantized values are not digitally encoded in QIM, the number of reconstruction values in each quantizer is not a design constraint, as it is in the design of a conventional quantizer. The lack of a rate constraint in QIM suggests that quantizer design for QIM involves different condiderations than does quantizer design for rate-distortion performance. Lookabaugh has identified three types of advantages of vector quantizers vs. scalar quantizers. These advantages are called the space-filling, shape, and memory advantages. This paper investigates whether all of these advantages are useful in the context of QIM. QIM performance of various types of quantizers is presented and a heuristic sphere-packing argument is used to show that, in the case of high-resolution quantization and a Gaussian attack channel, only the space-filling advantage is necessary for nearly optimal QIM performance. This is important because relatively simple quantizers are available that do not provide shape and memory gain but do give a space-filling gain.
Detection and partial characterization of a human mast cell carboxypeptidase. (1987)

Using a high performance liquid chromatography assay that detects the cleavage of the C-terminal leucine from angiotensin I, we have identified a carboxypeptidase activity in mast cells from human lung and in dispersed mast cell preparations from human skin. The enzyme activity was detected in a preparation of dispersed human mast cells from lung of greater than 99% purity and was released with histamine after stimulation with goat anti-human IgE. In nine preparations of dispersed human mast cells from lung of 10 to 99% purity, net percentage of release of carboxypeptidase correlated with the release of histamine, localizing carboxypeptidase to mast cell secretory granules. The enzyme activity was also detected in preparations of dispersed human mast cells from skin and in extracts of whole skin. The inhibitor profile and m.w. of carboxypeptidase activity from preparations of dispersed mast cells from skin was similar to that from dispersed mast cells from lung. Mast cell carboxypeptidase had a m.w. on gel filtration of 30,000 to 35,000. The enzyme in crude lysates of dispersed mast cell preparations had optimal activity between pH 8.5 and 9.5 and was inhibited by potato inhibitor, which distinguished it from carboxypeptidase in cultured human foreskin keratinocytes and adult fibroblasts, and from other proteolytic mast cell enzymes. The enzyme activity was also inhibited by EDTA, o-phenanthroline, and, to a small extent, by 8-OH quinoline, but not by Captopril, soybean trypsin inhibitor, or pepstatin. These findings demonstrate that human mast cell secretory granules contain carboxypeptidase in addition to tryptase and chymase. It appears that mast cells from skin may have a higher content of carboxypeptidase than do mast cells from lung.

Hydrodynamic analysis of a banbury mixer 2‐D flow simulations for the entire mixing chamber (1989)

Abstract Banbury mixers are widely used in polymer processing. The mechanics of flow in the chamber of an internal mixer are complex and difficult to analyze due to the complicated geometry and the highly transient character of the flow. For this work, a fluid dynamics analysis package—FIDAP, using the finite element method, was implemented to simulate the flow patterns for a Banbury B mixer. A 2‐D flow analysis was carried out for the whole mixing chamber with two counter‐rotating rotors. A power‐law model fluid was used to characterize the rheological behavior of the mixture. 18 different geometries were selected to represent the relative position of the two rotors during their revolution. Streamlines and pressure contours were plotted for each geometry. Transient pressure profiles at fixed locations in the chamber wall were compared with experimental data. The comparison shows good agreement between theoretical predictions and experimental observations.
Reduction of the Attenuation Constant of Microstrip (Short Papers) (1974)

Modifications to a normal microstrip transmission line are proposed, with the aim of reducing the attenuation constant of the line. The results of a computer analysis of a structure containing multilayers of dielectric show that significant reductions in attenuation appear possible.
Common Atlas Format and 3D Brain Atlas Reconstructor: Infrastructure for Constructing 3D Brain Atlases (2012)

One of the challenges of modern neuroscience is integrating voluminous data of diferent modalities derived from a variety of specimens. This task requires a common spatial framework that can be provided by brain atlases. The first atlases were limited to two-dimentional presentation of structural data. Recently, attempts at creating 3D atlases have been made to offer navigation within non-standard anatomical planes and improve capability of localization of different types of data within the brain volume. The 3D atlases available so far have been created using frameworks which make it difficult for other researchers to replicate the results. To facilitate reproducible research and data sharing in the field we propose an SVG-based Common Atlas Format (CAF) to store 2D atlas delineations or other compatible data and 3D Brain Atlas Reconstructor (3dBAR), software dedicated to automated reconstruction of three-dimensional brain structures from 2D atlas data. The basic functionality is provided by (1) a set of parsers which translate various atlases from a number of formats into the CAF, and (2) a module generating 3D models from CAF datasets. The whole reconstruction process is reproducible and can easily be configured, tracked and reviewed, which facilitates fixing errors. Manual corrections can be made when automatic reconstruction is not sufficient. The software was designed to simplify interoperability with other neuroinformatics tools by using open file formats. The content can easily be exchanged at any stage of data processing. The framework allows for the addition of new public or proprietary content.
Wideband and Dual-Band Design of a Printed Dipole Antenna (2008)

A wideband and dual-band dipole antenna with an integrated balun feed is given. First, the antenna structure is optimized and a 41.5% bandwidth is obtained where voltage standing wave ratio (VSWR) is less than 2. In order to further get a larger bandwidth and dual-band capabilities of this antenna, some rectangle apertures are etched onto the antenna surface, and a better dipole antenna is fabricated. Through investigating rectangle aperture with different sizes, a 47.8% bandwidth is obtained at L-band, and a 15.1% bandwidth comes true at S-band. Agreement between calculations and measurements is very good. The result indicates that the novel design not only may obtain better wideband characteristic but also can let the dipole antenna work at L- and S-bands.
Vasopressin V2 Receptor Binding Is Down-Regulated during Renal Escape from Vasopressin-Induced Antidiuresis (2000)

This study evaluated whether renal escape from vasopressin-induced antidiuresis is associated with alterations of vasopressin V2 receptor binding in the kidney inner medulla. A radioligand binding assay was developed using a novel iodinated vasopressin V2 receptor antagonist to analyze vasopressin V2 receptor binding in kidney inner medullary tissue from three groups of rats: normal rats maintained on ad libitum water intake, rats treated with 1-deamino-[8-d-arginine]vasopressin (DDAVP), and rats treated with DDAVP that were also water loaded to induce renal escape from antidiuresis. Analysis of the binding data showed that DDAVP treatment reduced vasopressin V2 receptor binding to 72% of normal levels. Water loading induced a marked further down-regulation of vasopressin V2 receptor binding. This receptor down-regulation began by day 2 of water loading, which correlated with the initiation of renal vasopressin escape; by day 3 of water loading, vasopressin V2 receptor expression fell to 43% of DDAVP-treated levels. No differences in vasopressin V2 receptor binding affinities were found among the three groups. This study demonstrates that vasopressin V2 receptor binding capacity is down-regulated during renal escape from vasopressin-induced antidiuresis and suggests that both vasopressin-dependent mechanisms as well as vasopressin-independent mechanisms associated with water loading are involved in this receptor down-regulation.

New Method Combines Simulation and Novel Spreadsheet Tools to Enable Direct Optimization of Expansion Decisions in a Giant Heavy-Oil Field (2007)

Summary Giant, geologically complex heavy-oil fields can take decades to develop, so development decisions made early in the life of the field can have long-range implications. Decision and risk analysis (D&RA) is often needed to make decisions that will maximize the risk-adjusted economic benefit. Unfortunately, in large fields, D&RA can be very challenging because of the large number of variables and the endless number of development and expansion scenarios to analyze. The time needed to complete a D&RA can become prohibitive when full-field reservoir simulation is the main tool for forecasting primary production and well count, with one simulation taking many hours or days to complete. This paper describes two new methods developed to overcome these challenges for a specific depletion-drive heavy-oil reservoir: a method for optimally populating a model with hundreds of horizontal wells, and a method to optimize expansion decisions quickly and directly. The utility of these tools has not been determined for other reservoirs and/or recovery mechanisms. A semiautomated spreadsheet-and-simulation method was developed to quickly place and select hundreds to thousands of hypothetical/future horizontal wells in a multimillion-gridblock model. Because the method automatically accounted for all model static properties and their effects on dynamic production response, the hypothetical wells had productivity characteristics very similar to the actual drilled wells placed in the model. A multivariate nonlinear interpolation method was developed that enabled full-field forecasts—for any combination of acreage allocation, well count, drilling order, and field rate constraint—to be calculated in less than 5 seconds, compared to approximately 20 hours for traditional simulation. Extensive validation work showed that well count and production curves from the spreadsheet virtually overlaid those obtained using traditional simulation of the particular expansion scenario. Such close agreement was possible because the basis of the spreadsheet forecast was utilization of traditional simulation forecasts from a handful of relevant cases. A key breakthrough beyond just fast forecasting was the coupling of the following three components inside the same spreadsheet: the fast forecasting method, calculation of an economic indicator/objective function (NPV), and commercial optimization tools. This linkage made possible, perhaps for the first time (at least at this scale), realization of direct optimization of any development scenario in a matter of minutes to a few hours, depending on the number of variables being optimized.
Harnessing Surface-Functionalized Metal–Organic Frameworks for Selective Tumor Cell Capture (2017)

A platform based on a metal-organic framework (MOF) bearing free carboxylic acid groups has been developed for tumor cell capture and potential drug screening applications. A zinc-based MOF expressing uncoordinated carboxylic acids (ZnMOF-COOH) was grown on a ZnO substrate. Post-synthetic modification (PSM) of the acid groups gave a composite material that expressed peptide linkages and allowed the immobilization of anti-epithelial cell adhesion molecule (anti-EpCAM) antibody. This strategy offers a universal method for the controllable immobilization of antibodies and even enzymes on the surface of a MOF. The resulting immunotrapper exhibited excellent capture ability, demonstrating high efficiency and selectivity towards EpCAM-positive tumor cells. The promotion of tumor cell adhesion is attributed to the 3-dimentional (3D) structure of the composite, which revealed spine-like microstructures.
Self Consciousness and Clothing Purchase Criteria of Korean and United States College Women (1993)

Relationships between criteria individuals use in the purchase of clothing and the individual trait of public and private self-consciousness were examined and compared between two cultural groups (United States and Korean). Eighty-two females from one U.S. college and 92 females from two Korean colleges participated in the study by completing a questionnaire which explored the importance of criteria used in the purchase of clothing, private and public self-consciousness, and demographic characteristics. Significant relationships between the trait of public self-consciousness and the importance of fashion and attractiveness as clothing purchase criteria were found for both cultural groups. A significant interaction effect was found between self-consciousness and cultural group for the importance of brand name as a clothing purchase criterion. Individual and cultural differences in consumer decision making process are discussed
Constancy in Human Sperm DNA Content (1974)

The frequency distribution of DNA content of human sperm was measured in an automated flow microfluorometer. The flow method measures the DNA content by quantifying the amount of fluorescence emitted by the fluorescent Feulgen stained DNA of single sperm cells suspended in microdroplets. The variability in the mean value for the haploid amount of DNA in sperm from 15 randomly chosen donors was less than 1%. Statistical tests on the observed frequency distribution data indicated that each sperm population probably consists of two homogenous components present in almost equal proportions but differing in mean DNA content. The difference in their modal values for DNA is within the range of known values of DNA difference between the two sex chromosomes. Sperm of donors segregating balanced translocations, when compared to the random samples as a class, showed greater variability in the mean DNA content.
Influence of global fluorination on chloramphenicol acetyltransferase activity and stability (2006)

Varied levels of fluorinated amino acid have been introduced biosynthetically to test the functional limits of global substitution on enzymatic activity and stability. Replacement of all the leucine (LEU) residues in the enzyme chloramphenicol acetyltransferase (CAT) with the analog, 5',5',5'-trifluoroleucine (TFL), results in the maintenance of enzymatic activity under ambient temperatures as well as an enhancement in secondary structure but loss in stability against heat and denaturants or organic co-solvents. Although catalytic activity of the fully substituted CAT is preserved under standard reaction conditions compared to the wild-type enzyme both in vitro and in vivo, as the incorporation levels increase, a concomitant reduction in thermostability and chemostability is observed. Circular dichroism (CD) studies reveal that although fluorination greatly improves the secondary structure of CAT, a large structural destabilization upon increased levels of TFL incorporation occurs at elevated temperatures. These data suggest that enhanced secondary structure afforded by TFL incorporation does not necessarily lead to an improvement in stability.
Two Minor Diterpene Glycosides from the Leaves of <i>Stevia rebaudiana</i> (2011)

Two new new diterpene glycosides, 13-[(2-O-(6-O-beta-D-glucopyranosyl)-beta-D-glucopyranosyl-beta-D-glucopyranosyl)oxy] kaur-16-en-18-oic acid beta-D-glucopyranosyl ester (1) and 13-[(2-O-beta-D-glucopyranosyl-3-O-beta-D-fructofuranosyl-beta-D-glucopyranosyl)oxy] kaur-16-en-18-oic acid beta-D-glucopyranosyl ester (2) were isolated from the leaves of Stevia rebaudiana, along with the known steviol glycosides stevioside, rebaudiosides A-F and dulcoside A. The structures of the two new compounds were established on the basis of extensive 2D NMR (COSY, HSQC, and HMBC), MS and chemical studies.
Self-Assembling Thiophene Dendrimers with a Hexa-<i>peri</i>-hexabenzocoronene Core−Synthesis, Characterization and Performance in Bulk Heterojunction Solar Cells (2009)

The solid state organization of molecules is an important factor in determining the performance of organic electronic devices. In bulk heterojunction (BHJ) solar cells, the arrangement of electron donor and acceptor materials into distinct crystalline phases of ideal size and distribution can lead to better power conversion efficiencies. The use of fluorenyl hexa-peri-hexabenzocoronene (FHBC) 2 in this study has highlighted the importance of molecular organization to device performance. FHBC compounds 6, 8, and 10, functionalized with a series of thiophene dendrons, were synthesized using Suzuki−Miyaura coupling in high yields. In UV−vis and 1H NMR spectroscopic studies, all FHBC derivatives showed self-association in solution. Hexagonal packing of columnar structures was observed for solid state samples of FHBC 2 and 8 in two-dimensional wide-angle X-ray scattering experiments. In thin film X-ray experiments, ordered structures were observed in blends of FHBC 2 and fullerene acceptor materials indicating that there is phase separation between the donor and acceptor materials and that the self-organization of the FHBC material is unaffected. While the large thiophene dendritic substituent attached to compound 10 broadened its UV−vis absorption profile, the solid state morphology is altered by the bulky thiophene dendrons. These molecular structure variations are reflected in the performance characteristics of BHJ solar cell devices fabricated using these FHBC compounds as electron donor materials. Power conversion efficiency of 2.5% was achieved for a device containing compound 10 with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as the acceptor material. This compares favorably with devices fabricated with pure dendritic thiophene materials and illustrates the positive effect of molecular self-organization on device performance.
