Coherent optical image delay device using a BSO phase-conjugate mirror and its applications (1983)

The Bi12SiO20 (BSO) crystal has been used as an optical storage medium for a 2-D optical field to obtain a delayed coherent optical image. The method used the BSO crystal in a four-wave mixing configuration to produce a phase-conjugated wave front. It has been demonstrated that the image of a vinyl film could be compared with its stored image over a time delay varying from 40 msec to a few seconds. Measurements have also been made of the changes of optical path length within this inhomogeneous medium.
Application of Fast X-ray CT Scanner to Visualization of Bubbles in Fluidized Bed. (2000)

A fast-scanning X-ray CT system, designed for measuring dynamic events in multiphase fluids, was used to obtain the transient 2-dimensional cross sectional gas-phase distribution in a fluidized bed. The captured data was sent to a PC for image reconstruction, and the density distributions across the column cross section were visualized. Using image processing techniques, a pseudo 3-dimensional image of bubbles was obtained. The spatial and time resolutions of the system were sufficient for the measurement of ascending bubble behavior in a fluidized bed with fine particles. Bubble shape, interfacial area, and bubble holdup over the cross section can be measured by this system.
The effect of Acemannan Immunostimulant in combination with surgery and radiation therapy on spontaneous canine and feline fibrosarcomas (1995)

Eight dogs and five cats with histopathologically confirmed fibrosarcomas were treated with Acemannan Immunostimulanta in combination with surgery and radiation therapy. These animals had recurring disease that had failed previous treatment, a poor prognosis for survival, or both. Following four to seven weekly acemannan treatments, tumor shrinkage occurred in four (greater than 50%; n = 2) of 12 animals, with tumors accessible to measurement. A notable increase in necrosis and inflammation was observed. Complete surgical excision was performed on all animals between the fourth and seventh week following initiation of acemannan therapy. Radiation therapy was instituted immediately after surgery. Acemannan treatments were continued monthly for one year. Seven of the 13 animals remain alive and tumor-free (range, 440+ to 603+ days) with a median survival time of 372 days. The data suggests that Acemannan Immunostimulant may be an effective adjunct to surgery and radiation therapy in the treatment of canine and feline fibrosarcomas.
Ratio of remnant-like particle-cholesterol to serum total triglycerides is an effective alternative to ultracentrifugal and electrophoretic methods in the diagnosis of familial type III hyperlipoproteinemia. (1999)

When used in an appropriate target population, the RLP-C-to-total TG ratio is a convenient and effective alternative to ultracentrifugal and electrophoretic methods for diagnosing type III HLP.
Interference Microscopy Investigation of the Influence of Regular Intergrowth Effects in MFI-Type Zeolites on Molecular Uptake (2001)

Interference microscopy is applied to carry out investigations of the influence of the regular intergrowth effects commonly observed in large silicalite-1 crystals on adsorption/desorption of isobutane. The intracrystalline concentration profiles measured by interference microscopy during adsorption of isobutane are compared with those simulated using the Monte Carlo method. The comparison of the simulated and the measured profiles allows the possibility that the uptake of isobutane from the gas phase into silicalite-1 crystals proceeds through the internal interfaces separating the intergrowth sections of the crystals to be ruled out. The diffusion coefficient of isobutane obtained by comparing the simulated and the measured concentration profiles is found to be in agreement with the previously reported diffusivities of isobutane in silicalite-1.
The Magnetic Resonance Imaging Contrast Agent Mangafodipir Exerts Antitumor Activity via a Previously Described Superoxide Dismutase Mimetic Activity (2006)

To the Editor: 

It was recently described in Cancer Research by Laurent et al. ( [1][1]) how low molecular weight superoxide dismutase (SOD) mimetics increase H2O2 levels, which in turn killed colon (CT26) and liver (Hepa 1-6) tumor cells. In contrast, the SOD mimetics stimulated proliferation of
Conformationally defined adrenergic agents. 13. Conformational and steric aspects of the inhibition of phenylethanolamine N-methyltransferase by benzylamines (1988)

Compounds of the benzylamine (BA) class are potent inhibitors of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28). Restriction of the aminomethyl side chain through its incorporation into a cyclic framework as in 1,2,3,4-tetrahydroisoquinoline (THIQ) or 2,3,4,5-tetrahydro-1H-2-benzazepine (THBA) results in enhanced potency as an inhibitor, suggesting a conformational effect in the binding of BAs to the active site; however, these ring systems still retain a high degree of flexibility. We have synthesized a series of conformationally defined analogues of benzylamine in order to probe the effect of conformation, as well as the influence of steric bulk, on PNMT inhibition by this class of ligands. In addition, 1-, 3-, and 4-methyl-substituted THIQs were synthesized and evaluated as flexible models for steric bulk tolerance about this ring system. Substitution by a methyl group on either benzylic position of THIQ results in diminished activity as a PNMT inhibitor; however, 3-methyl-THIQ shows enhanced activity as an inhibitor vs THIQ itself. Full conformational restriction of the BA side chain in analogues 4-8 results in a dramatic loss in inhibitor potency. We attribute this effect to a negative steric interaction between the alkyl bridging units above (or below) the heterocyclic ring systems and an active-site amino acid residue. Conformational restriction of THIQ employing a bridging unit that is not located above (or below) the ring system results in only slightly diminished activity compared to THIQ itself. The relative activities of 4-8 were examined in terms of the conformational descriptors tau 1 and tau 2. Although there is no correlation between tau 1 and activity as a PNMT inhibitor, a qualitative relationship between tau 2 (endo or exo) and activity with PNMT is apparent. We believe that the binding of the N-H and/or N-lone pair of electrons may influence the spatial orientation of these molecules at the active site, resulting in positive binding interactions for compounds 4 and 8 and negative interactions for analogues 5-7. The results from the current investigation are compared to those obtained from a similar study involving conformationally defined amphetamines.
Deploying Video-on-Demand Services on Cable Networks (2007)

Efficient video-on-demand (VoD) is a highly desired service for media and telecom providers. VoD allows subscribers to view any item in a large media catalog nearly-instantaneously. However, systems that provide this services currently require large amounts of centralized resources and significant bandwidth to accommodate their subscribers. Hardware requirements become more substantial as the service providers increase the catalog size or number of subscribers. In this paper, we describe how cable companies can leverage deployed hardware in a peer- to-peer architecture to provide an efficient alternative We propose a distributed VoD system, and use real measurements from a deployed VoD system to evaluate different design decisions. Our results show that with minor changes, currently deployed cable infrastructures can support a video-on-demand system that scales to a large number of users and catalog size with low centralized resources.
Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor (2013)

This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. For devices which contain liquids or needs to be enclosed in a vacuum, the packaging can account for up to 80% of the total cost of the device. The first part of this thesis presents the integration scheme for an optical dye thin film NO2-gas sensor, designed using cost-efficient implementations of wafer-scale methods. This work includes design and fabrication of photonic subcomponents in addition to the main effort of integration and packaging of the dye-film. A specific proof of concept target was for NO2 monitoring in a car tunnel. The second part of this thesis deals with the wafer-scale packaging methods developed for the sensing device. The developed packaging method, based on low-temperature plastic deformation of gold sealing structures, is further demonstrated as a generic method for other hermetic liquid and vacuum packaging applications. In the developed packaging methods, the mechanically squeezed gold sealing material is both electroplated microstruc- tures and wire bonded stud bumps. The electroplated rings act like a more hermetic version of rubber sealing rings while compressed in conjunction with a cavity forming wafer bonding process. The stud bump sealing processes is on the other hand applied on completed cavities with narrow access ports, to seal either a vacuum or liquid inside the cavities at room temperature. Additionally, the resulting hermeticity of primarily the vacuum sealing methods is thoroughly investigated. Two of the sealing methods presented require permanent mechanical fixation in order to complete the packaging process. Two solutions to this problem are presented in this thesis. First, a more traditional wafer bonding method using tin-soldering is demonstrated. Second, a novel full-wafer epoxy underfill-process using a microfluidic distribution network is demonstrated using a room temperature process.
Determining Optimal Reliability Targets Through Analysis of Product Validation Cost and Field Warranty Data (2005)

This work develops a new methodology to minimize the life cycle cost of a product using the decision variables controlled by a reliability/quality professional during a product development process. This methodology incorporates all product dependability-related activities into a comprehensive probabilistic cost model that enables minimization of the product's life cycle cost using the product dependability control variables. The primary model inputs include the cost of ownership of test equipment, forecasted cost of warranty returns, and environmental test parameters of a product validation program. Among these parameters, an emphasis is placed upon test duration and test sample size for durability related environmental tests. The warranty forecasting model is based on data mining of past warranty claims, parametric probabilistic analysis of the existing field data, and a piecewise application of several statistical distributions. The modeling process is complicated by insufficient knowledge about the relationship between product quality and product reliability. This can be attributed to the lack of studies establishing the effect of product validation activities on future field failures, overall lack of comprehensive field failure studies, and the market's dictation of warranty terms as opposed to warranties based on engineering rationale. As a result of these complicating factors an innovative approach to estimating the quality-reliability relationship using probabilistic methods and stochastic simulation has been developed. The overall cost model and its minimization are generated using a Monte Carlo method that accounts for the propagation of uncertainties from the model inputs and their parameters to the life cycle cost solution. This research provides reliability and quality professionals with a methodology to evaluate the efficiency of a product validation program from a life cycle cost point of view and identifies ways to improve the validation test flow by adjusting test durations, sample sizes, and equipment utilization. Solutions balance a rigorous theoretical treatment and practical applications and are specifically applied to the electronics industry.

Bayesian Regression Modeling with Interactions and Smooth Effects (2000)

Abstract There have been many recent suggestions as to how to build and estimate flexible Bayesian regression models, using constructs such as trees, neural networks, and Gaussian processes. Although there is much to commend these methods, their implementation and interpretation can be daunting for practitioners. This article presents a spline-based methodology for flexible Bayesian regression that is quite simple in terms of computation and interpretation. Smooth bivariate interactions are modeled in an economical and apparently novel way, and prior distributions that penalize complexity are used. Predictions can be based on either model selection or model averaging. Taking computation, interpretation, and predictive performance into account, the method is seen to perform well when applied to simulated and real data.

ERp57 Is a Multifunctional Thiol-Disulfide Oxidoreductase (2004)

The thiol-disulfide oxidoreductase ERp57 is a soluble protein of the endoplasmic reticulum and the closest known homologue of protein disulfide isomerase. The protein interacts with the two lectin chaperones calnexin and calreticulin and thereby promotes the oxidative folding of newly synthesized glycoproteins. Here we have characterized several fundamental structural and functional properties of ERp57 in vitro, such as the domain organization, shape, redox potential, and the ability to catalyze different thiol-disulfide exchange reactions. Like protein disulfide isomerase, we find ERp57 to be comprised of four structural domains. The protein has an elongated shape of 3.4 +/- 0.1 nm in diameter and 16.8 +/- 0.5 nm in length. The two redox-active a and a' domains were determined to have redox potentials of -0.167 and -0.156 V, respectively. Furthermore, ERp57 was shown to efficiently catalyze disulfide reduction, disulfide isomerization, and dithiol oxidation in substrate proteins. The implications of these findings for the function of the protein in vivo are discussed.
Magnetic field analysis for distance measurement in 3D positioning applications (2016)

This paper proposes an analysis of the quasi-stationary magnetic field generated by coils and its applicability to 3D positioning applications. Starting from a theoretical background, an approximation of the induced voltage in a sensor coil is developed and analyzed. In particular, the introduced approximation error is shown to be lower than 5 mm over a 20 m range. Finally, the developed model is compared against a well-established theoretical model developed in the literature and against in-field measurements in the range 0.5 m to 5 m. Results show that the developed model may be suitable for magnetic field based distance measurements in low complexity 3D positioning applications.
Predicting chain conformation and entanglement of polymers from chemical structure (1992)

Abstract The characteristic ratio C ∞ and the entanglement molecular weight M e are two key molecular parameters that control melt viscoelasticity, solid mechanical (brittle/ductile) behavior, and adhesion of polymers. We show that the characteristic ratio C ∞ and the entanglement molecular weight M e can be predicted from chemical structure by group additivity with uncertainties usually less than ∼ 7% for C ∞ and ∼ 15% for M e , comparable with the accuracies of experimental values.
Field Plot Techniques for Selecting Increased Once-over Harvest Yields in Pickling Cucumbers1 (1978)

Abstract Three harvest methods and 3 plot sizes for estimating yields in pickling cucumbers (Cucumis sativus L.) were examined. The correlation between dollar values for a simulated once-over harvest and successive harvest were low (r < .16). Correlation between once-over harvest value and fruit number was .84, while correlation between once-over harvest value and mature fruit number was only .36. The correlation of .84 was high enough to warrant use of fruit number as a primary trait in selection for increased value. Use of fruit number as an estimate of yield would eliminate the grading and weighing processes needed to compute value. An efficient plot size for estimating mean differences between lines was 3.6m 2 .
Asynchronous Adaptation and Learning Over Networks—Part I: Modeling and Stability Analysis (2014)

In this work and the supporting Parts II and III of this paper, also in the current issue, we provide a rather detailed analysis of the stability and performance of asynchronous strategies for solving distributed optimization and adaptation problems over networks. We examine asynchronous networks that are subject to fairly general sources of uncertainties, such as changing topologies, random link failures, random data arrival times, and agents turning on and off randomly. Under this model, agents in the network may stop updating their solutions or may stop sending or receiving information in a random manner and without coordination with other agents. We establish in Part I conditions on the first and second-order moments of the relevant parameter distributions to ensure mean-square stable behavior. We derive in Part II expressions that reveal how the various parameters of the asynchronous behavior influence network performance. We compare in Part III the performance of asynchronous networks to the performance of both centralized solutions and synchronous networks. One notable conclusion is that the mean-square-error performance of asynchronous networks shows a degradation only in the order of O(ν), where ν is a small step-size parameter, while the convergence rate remains largely unaltered. The results provide a solid justification for the remarkable resilience of cooperative networks in the face of random failures at multiple levels: agents, links, data arrivals, and topology.
Two‐Dimensional Iterative Processing for DAB Receivers Based on Trellis‐Decomposition (2012)

We investigate iterative trellis decoding techniques for DAB, with the objective of gaining from processing 2D‐blocks in an OFDM scheme, that is, blocks based on the time and frequency dimension, and from trellis decomposition. Trellis‐decomposition methods allow us to estimate the unknown channel phase since this phase relates to the sub‐trellises. We will determine a‐posteriori sub‐trellis probabilities, and use these probabilities for weighting the a‐posteriori symbol probabilities resulting from all the sub‐trellises. Alternatively we can determine a dominant sub‐trellis and use the a‐posteriori symbol probabilities corresponding to this dominant sub‐trellis. This dominant sub‐trellis approach results in a significant complexity reduction. We will investigate both iterative and non‐iterative methods. The advantage of non‐iterative methods is that their forwardbackward procedures are extremely simple; however, also their gain of 0.7 dB, relative to two‐symbol differential detection (2SDD) at a BER of 10 −4 , is modest. Iterative procedures lead to the significantly larger gain of 3.7 dB at a BER of 10 −4 for five iterations, where a part of this gain comes from 2D processing. Simulations of our iterative approach applied to the TU‐6 (COST207) channel show that we get an improvement of 2.4 dB at a Doppler frequency of 10 Hz.
Overview of heavy oil upgrading technology (2006)

Utilization of heavy crude including unconventional oil may be indispensable to cope with an increasing demand of crude oil in developing countries, such as China and India. Upgrading technologies and processes are, therefore, important for utilizing such heavy oils. In the present paper, upgrading technologies of carbon rejection and hydrogen addition processes are reviewed. Coking and SDA are focused as carbon rejection process. Hydrogen thermal cracking process based on slurry technology is focused as hydrogen addition process. Characteristics of such processes and possibility for integration of SDA and hydrogen thermal cracking are presented.
Immune response to the <i>p</i>-azobenzenearsonate (ABA)-GAT conjugate: role of I region genes in the selective activation of ABA-specific or GAT-specific T helper cells. (1982)

Immunization of GAT non-responders with ABA-GAT leads to the activation of ABA-specific T cells. These hapten specific T cells are Lyt-1+2- helper cells capable of inducing anti-ABA antibody responses in vivo or B cell activation in vitro. However, their activation does not modify the GAT non-responder phenotype. Immunization of GAT responder mice with ABA-GAT activates GAT-specific T cells, which can help anti-ABA and anti-GAT antibody responses. Since the responder and non-responder strains used in these experiments differ only in the alleles present in the I region, the results suggest that the selective activation of hapten- or carrier-specific T cells is controlled by I region genes. Yet sensitization of the two strains with ABA-KLH or ABA-Tyr induces KLH-specific or ABA-specific T cells, respectively. This provides further evidence that the use of an immunogenic carrier prevents the expression of the hapten-specific T cell clones present in the repertoire of both responder and non-responder animals. Macrophages from responder animals pulsed with ABA-GAT can present ABA and GAT determinants to T cells. Thus, the absence of ABA-specific T cells in responders primed with ABA-GAT and their presence in GAT non-responders reflects a competition between hapten- and carrier-specific T cells and not an epitope selection by macrophages. We discuss the significance of the results in terms of Ir genes determining the self-plus-antigen-specific T cell repertoire rather than controlling antigen presentation by macrophages.
