Design data modeling with versioned conceptual configuration (2003)

Control of versions and time-varying configurations of design data is a very important issue in computer-aided design environments. A new data modeling scheme to facilitate their management is proposed. The basic idea is to manage complicatedly related time-varying design data in terms of well-defined versions and configurations of conceptual design artifacts. The modeling scheme views the design database as a collection of conceptual objects and representation objects. Representation objects are abstractions of conventional design data files and configurations of conceptual objects are cast on them as the management structure. To facilitate design data management through the conceptual objects, the scheme provides constructs for modeling version variant and invariant configurations and for modular management of large configurations. Operations for design data manipulation and a mechanism for maintaining design database consistency are also presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Surface lanthanide activator doping for constructing highly efficient energy transfer-based nanoprobes for the on-site monitoring of atmospheric sulfur dioxide (2019)

The sensitive and on-site detection of sulfur dioxide (SO<sub>2</sub>) is in great demand in the fields of food safety and environmental protection. Here, we developed a novel upconversion nanoprobe based on the luminescence energy transfer mechanism for monitoring the atmospheric SO<sub>2</sub> concentrations. The lanthanide emitters, Tm<sup>3+</sup> ions, were optimized to be doped on the surface layer of the upconversion nanoparticles to improve their energy transfer efficiency by minimizing the distance between the emitters and the surface quencher, a cyanine dye. As a proof-of-concept, the optimal nanoprobe was utilized to detect SO<sub>2</sub> water derivatives, bisulfite ions, exhibiting a linear luminescence increase in the range of 1 nM to 10 nM. Furthermore, we assembled the cyanine-modified upconversion nanoparticles onto a test paper, and used a smartphone-based detection platform to achieve portable and visual detection of SO<sub>2</sub>. The test paper showed a strong luminescence stability, homogeneity and good anti-interference. The limit of detection for SO<sub>2</sub> gas was found to be 1 ng L<sup>-1</sup>. This novel upconversion test paper was also demonstrated to directly monitor the concentration of SO<sub>2</sub> gas in atmosphere.
Distinct Effects of Recombinant Tenascin‐R Domains in Neuronal Cell Functions and Identification of the Domain Interacting with the Neuronal Recognition Molecule F3/11 (1996)

We have identified distinct domains of the rat extracellular matrix glycoprotein tenascin-R using recombinant fragments of the molecule that confer neuronal cell functions. In short-term adhesion assays (0.5 h), cerebellar neurons adhered best to the fragment representing the fibrinogen knob (FG), but also the fibronectin type III (FN) repeats 1-2 and 6-8. FG, FN1-2 and FN3-5 were the most repellent fragments for neuronal cell bodies. Neurites and growth cones were strongly repelled from areas coated with fragments containing the cysteine-rich stretch and the EGF-like domains (EGF-L), FN1-2, FN3-5 and FG. Polarization of morphology of hippocampal neurons was exclusively associated with FG, while EGF-L prevented neurite outgrowth altogether. The binding site of the neuronal receptor for tenascin-R, the immunoglobulin superfamily adhesion molecule F3/11, was localized to EGF-L. The combined observations show distinct, but also overlapping functions for the different tenascin-R domains. They further suggest the existence of multiple neuronal tenascin-R receptors which influence the response of neurons to their extracellular matrix environment.
Fast Low Fidelity Microsimulation of Vehicle Traffic on Supercomputers (1993)

A set of very simple rules for driving behavior used to simulate roadway traffic gives realistic results. Because of its simplicity, it is easy to implement the model on supercomputers (vectorizing and parallel), where we have achieved real time limits of more than 4~million~kilometers (or more than 53~million vehicle sec/sec). The model can be used for applications where both high simulation speed and individual vehicle resolution are needed. We use the model for extended statistical analysis to gain insight into traffic phenomena near capacity, and we discuss that this model is a good candidate for network routing applications.

Thioltransferase in human red blood cells: purification and properties (1991)

Thioltransferase activity was identified and the enzyme purified to apparent homogeneity from human red blood cells. Activity was measured as glutathione-dependent reduction of the prototype substrate hydroxyethyl disulfide; formation of oxidized glutathione (GSSG) was coupled to NADPH oxidation by GSSG reductase (1 unit of activity = 1 mumol/min of NADPH oxidized). The thioltransferase-GSH-GSSG reductase system was shown also to catalyze the regeneration of hemoglobin from the mixed disulfide hemoglobin-S-S-glutathione (HbSSG) and to reactivate the metabolic control enzyme phosphofructokinase (PFK) after oxidation of its sulfhydryl groups. On a relative concentration basis, thioltransferase was about 1200 times more efficient than dithiothreitol in reactivation of phosphofructokinase; e.g., 500 microM DTT was required to effect the same extent of reactivation as that of 0.4 microM TTase. The GSH plus GSSG reductase system without thioltransferase was ineffective for reduction of HbSSG or reactivation of PFK. The average amount of thioltransferase in intact erythrocytes was calculated to be 4.6 units/g of Hb at 25 degrees C. This level of activity is about the same as those of other enzymes that participate in sulfhydryl maintenance in red blood cells, such as GSSG reductase and glucose-6-phosphate dehydrogenase. These results suggest a physiological role for the thioltransferase in erythrocyte sulfhydryl homeostasis. Certain properties of the human erythrocyte thioltransferase resemble those of other mammalian thioltransferase and glutaredoxin enzymes. Thus, the human erythrocyte enzyme, purified about 28,000-fold to apparent homogeneity, is a single polypeptide with a molecular weight of 11,300. Its N-terminus is blocked, it is heat stable, and it contains four cysteine residues per protein molecule. However, the human erythrocyte thioltransferase is a distinct protein based on its amino acid composition. For example, it contains no methionine residues; whereas the related mammalian enzymes described to date have at least one internal methionine residue in their largely homologous sequences.
Synthesis of substituted pyrimidines, pyrazole[3,4-d]pyrimidines and imidazo[4,5-d]pyrimidines and evaluation of their antifungal activity. (1989)

Some pyrimidines, pyrazolo[3,4-d]pyrimidines and imidazo[4,5-d]pyrimidines bearing the 5-nitro- and 5-aminothienyl-2-sulfide functionalities on the pyrimidine nucleus were synthesized and evaluated for their antifungal activity against several strains of yeasts and dermatophytes. 4-Amino-2-pyrimidinyl-5'-nitro-2'-thienylsulfide (Va) resulted active against both yeasts and dermatophytes (about 30 fold less potent than Miconazole). Compds. (II b), (V b) and (VIII b) showed only a slight activity against dermatophytes, while the other compounds were inactive.
A control systems approach for the simulation of renal dynamic software phantoms for nuclear medicine (1999)

For renal dynamic studies, the COST B2 hybrid phantom is an example of an artificially created software phantom. Although this phantom is useful, it is not possible to implement the phantom in a self-consistent fashion to produce, for example, a collection of tracer in the bladder which is related to the flow from the kidneys. In this study control systems are used to provide a self-consistent model. A feed-forward control system was designed for the transport of DTPA in the human body using SIMULINK. The system is based on a three-compartment model described by a set of differential equations with flow rates which may be set by the operator. The differential uptake in the kidneys may also be specified, while the flow of tracer through the renal parenchyma and collecting system of each kidney is determined using two-parameter retention functions. Curves corresponding to normal or pathological conditions may be simulated for plasma, parenchyma, collecting system and bladder by appropriate selection of parameters. The system is user-friendly and can be used to simulate almost all conditions seen in patient studies. The next stage of using this information to design dynamic image simulations is in progress.

A Three-Dimensional Spatial Non-Linear Predictor for Television (1978)

This paper presents a three-dimensional non-linear prediction technique for use in differential pulse code modulation systems used to encode television signals. The prediction is a weighted sum of three estimates called representatives. Each representative is a nonlinear estimate based on previous pels in one of three planes containing the pel to be predicted. The paper contains an explanation of the technique, results of computer simulations of the algorithm and a comparison of the algorithm with other prediction procedures. The predictor is relatively insensitive to image statistics. Errors in the predictor input decay out with time.

Genetic Diversity and Its Conservation in Natural Populations of Plants (1996)

This paper reviews patterns of genetic diversity in natural populations of plants: patterns which have emerged from more than 70 years of genecological investigation and 30 years of allozyme analysis. The compelling conclusion to be drawn from these empirical studies is that genetic diversity in most plant species lies along the axis of environmental, and specifically habitat, variability. This predominance of genotype-environment correlations, a testimony to the power and ubiquity of natural selection, demands that strategies for the conservation of genetic diversity involve sampling or protection schemes which are stratified across environments or habitat-types. The genetic response of species' populations to their environment is affected, or constrained, by a range of intrinsic biological properties such as the breeding system and external processes such as those which cause fluctuations in population size. Insight into the impact of such forces on the genetic diversity and structure of natural populations has been the major gain from studies of allozyme variation. However, there is some doubt about the neutrality of allozyme loci, and often no correlation can be found between levels of

Preliminary Design of Tubular Composite Structures Using Netting Theory and Composite Degradation Factors (1995)

Abstract Tubular products and process vessels built using fiber-reinforced composite materials provide significant advantages in applications that require corrosion resistance, high strength, and light weight. A design approach based on netting theory is presented which enables engineers to develop preliminary structural designs for these structures using composite materials. The integration of creep, cyclic loading, and environmental degradation factors into initial design calculations is also discussed and illustrated.
Reducing Uncertainty in Reservoir Model Predictions: from Plume Evolution to Tool Responses (2013)

With the transition of geological carbon dioxide (CO2) storage from pilot to industrial scale, risk analysis has become pivotal for assessing the suitability of a storage site in satisfying regulatory requirements during and after injection. Risk analysis is inherently related to uncertainty quantification. This paper extends our previously developed workflows to quantify and propagate uncertainty from geological, geophysical and petrophysical data to project-level performance metrics including capacity, injectivity, and containment characteristics. We perform global sensitivity analysis to quantitatively link uncertainty in the computed performance metrics to the uncertainties in the underlying reservoir parameters. This enables one to identify measurements to reduce uncertainty estimates of reservoir performance metrics and predicted monitoring tool responses. We illustrate this workflow in a pre-injection uncertainty study for the Illinois Basin Decatur Project (IBDP). The reservoir model is built using geostatistical approach based on all available geophysical and petrophysical data including 3D seismic interpretation, results of special core analysis and injectivity tests. We focus on three groups of performance predictions: spatial extent of the CO2 saturation profile, partitioning of CO2, and predicted responses seen with the Westbay* multilevel groundwater characterization and monitoring system installed in the monitoring well. Based on multiple realizations of the reservoir model we evaluate the uncertainty range in pressures and CO2 saturations at the Westbay monitoring zones during the life of the project. Predicted measurements at the monitoring zones covering a depth interval between 1950 m and 2120 m are analyzed. Global sensitivity analysis is used to identify the key petrophysical properties of the reservoir whose uncertainties have the most effect on the uncertainty of the reservoir performance and measurement predictions. Results of this analysis provide valuable insight for targeted site characterization and design of the monitoring program.
Rate-User-Perceived-Quality Aware Replication Strategy for Video Streaming over Wireless Mesh Networks (2011)

In this research, we consider the replication strategy for the applications of video streaming in wireless mesh networks (WMNs). In particular, we propose a closed-form of optimal replication densities for a set of frames of a video streaming by exploiting not only the skewed access probability of each frame but also the skewed loss probability and skewed encoding rate-distortion information. The simulation results demonstrate that our method improves the replication performance in terms of user-perceived quality (UPQ) which includes: 1) minimum average maximum reconstructed distortion for high peak signal-to-noise ratio (PSNR), 2) small reconstructed distortion fluctuation among frames for smooth playback, and 3) reasonable average maximum transmission distance for continuous playback. Furthermore, the proposed strategy consumes smaller storage capacity compared to other existing optimal replication strategies. More importantly, the effect of encoding rate is carefully investigated to show that high encoding rate does not always gain high performance of replication for video streaming.
Spectral Moments of the Edge-Adjacency Matrix of Molecular Graphs. 2. Molecules Containing Heteroatoms and QSAR Applications (1997)

A novel substructural approach to structure−property and structure−activity relationships studies is proposed. The method is based on the computation of spectral moments of the edge-weighted adjacency matrix. In the present work, bond distances are used as bond weights in the diagonal entries of edge matrix. Spectral moments of the edge-weighted adjacency matrix are expressed in terms of structural fragments present in molecules via algebraic expressions. Boiling points of 58 alkyl halides were well described by the present approach, and this property was expressed as a linear combination of structural fragments of the studied molecules. QSAR applications of the novel approach are explored by studying the antifungal activity of benzyl alcohols. An equation expressing contributions of each substituent in benzyl alcohols to the antifungal activity is obtained. The methodology proposed here permits the rational design of novel compounds with improved activity, which is illustrated for benzyl alcohol derivatives.
Defensin-1, a peptide detected in the saliva of oral squamous cell carcinoma patients. (1999)

The saliva of patients with oral squamous cell carcinoma was subjected to reversed-phase HPLC, and a peak (P 14) was eluted with a linear gradient of acetonitrile. The molecular weight of P14 was 3,442 daltons by mass spectrometry. The results of amino acid sequencing by Edman degradation and homology studies indicated that P14 was consistent with a peptide, human alpha-defensin 1 (HNP-1) which belongs to the defensin family. The concentration of HNP-1 in the saliva of 6 squamous cell carcinoma patients before surgery and 11 after surgery was 12.3 +/- 8.6 and 6.5 +/- 5.9 micrograms/ml (mean +/- S.D.), respectively. In contrast, minimal amounts of HNP-1 were found in the saliva of adenocarcinoma patients and healthy volunteers. The concentration of salivary HNP-1 correlated positively with serum squamous cell carcinoma related antigen (SCC-Ag)level (r = 0.879, p < 0.01).
