Engineering Plastics and Their Commercial Development (1969)

Engineering plastics are those which possess physical properties enabling them to perform for prolonged use in structural applications, over a wide temperature range, under mechanical stress, and in difficult chemical and physical environments. In comparison with metals for a given application, plastics may offer such advantages as transparency, self-lubrication, economy in fabricating and decorating. Plastics can be flexible, they are electrical nonconductors and thermo insulators, with these properties being either advantages or disadvant ages, depending on use. Properties of plastics can be modified through the use of reinforcing agents, fillers, and chemical additives. Engineering applications for plastics include mechanical units under stress, low friction components, heat and chemical resistant units, electrical parts, housings, high light transmission applications, building construction functions, and many miscellaneous uses.
High Temperature Liquid Chromatography on a Poly(Styrene‐Divinylbenzene) Stationary Phase (2005)

Abstract The performance of poly(styrene‐divinylbenzene) stationary phase was evaluated for the separation of test compounds, alkyl aryl ketones, and barbiturates under reversed‐phase high performance liquid chromatography (RP‐HPLC) at high temperature (100°C–200°C) using water‐rich and superheated water as the eluent. Good separations with acceptable column efficiencies were achieved at high column temperatures. Van't Hoff plots for the separations were linear, which suggest that for selected compounds over the temperature range studied, no changes occurred in the retention mechanism. The high temperature RP‐HPLC separation technique was successfully applied to the separation of selected barbiturates using 100% pure water as the eluent.
Stoichiometric association of extrinsic cytochrome <i>c</i><sub>550</sub> and 12 kDa protein with a highly purified oxygen‐evolving photosystem II core complex from <i>Synechococcus vulcanus</i> (1992)

A highly purified, native photosystem II (PS II) core complex was isolated from thylakoids of Synechococcus vulcanus, a thermophilic cyanobacterium by lauryldimethylamine N-oxide (LDAO) and dodecyl beta-D-maltoside solubilization. This native PS II core complex contained, in addition to the proteins that have been well characterized in the core complex previously purified by LDAO and Triton X-100, two more extrinsic proteins with apparent molecular weights of 17 and 12 kDa. These two proteins were associated with the core complex in stoichiometric amounts and could be released by treatment with 1 M CaCl2 or 1 M alkaline Tris but not by 2 M NaCl or low-glycerol treatment, indicating that they are the real components of PS II of this cyanobacterium. N-Terminal sequencing revealed that the 17 and 12 kDa proteins correspond to the apoprotein of cytochrome c550, a low potential c-type cytochrome, and the 9 kDa extrinsic protein previously found in a partially purified PS II preparation from Phormidium laminosum, respectively. In spite of retention of these two extrinsic proteins, no homologues of higher plant 23 and 17 kDa extrinsic proteins could be detected in this cyanobacterial PS II core complex.

A gesture controlled human interface using an artificial retina chip (2002)

To realize advanced multi-media systems for use in computers, advanced home audio-visual equipment, games machines, public information systems, and so on, it is necessary to develop vision-based input methods, which do not require keyboards or joysticks. We have developed a flexible, high-speed and compact artificial retina (AR) chip module composed of an AR chip and a micro-processor for human interface systems. The AR chip is a novel type of CCD image sensor with versatile and high-speed on-chip processing capabilities. The features are suitable for human friendly input systems employing image information. We have also developed a unique gesture recognition algorithm, which is tailored for the AR chip. The gesture recognition system permits applications with gesture controlled human interfaces.
Structure Stability Study on a Newly Developed Nickel-Base Superalloy - Allvac 718Plus (2005)

Recently a new Ni base superalloy to be used at 700°C has been developed by ATI Allvac designated as Allvac ® 718Plus TM .The critical criterion for this alloy is long time structure stability at 700°C that is closely related to the nature of phases and their stability in this alloy.In this study phase identification of 718Plus at as-heat treated and long-term thermal exposed conditions was conducted by various means.Phase prediction of 718Plus was calculated by Thermo-Calc software and the detailed phase identification was conducted by SEM, TEM, EDS, SAD and XRD.Quantitative determination of different phases were conducted by electrolytic phase isolation and followed by micro-chemical analyses.The results show that alloy 718Plus is predominantly γ' strengthened alloy with very good structure stability at 700°C.The formation of δ phase occurred during heat treatment and thermal exposure.A new phase Ni 3 Al 0.5 Nb 0.5 with HCP structure was found.The phase precipitation behavior in combination with good mechanical properties makes 718Plus a very good candidate superalloy to be used at 700°C.
[Oral application of bacterial vaccine for infection prophylaxis (author's transl)]. (1980)

Guinea pigs were orally and subcutaneously immunized against Pseudomonas aeruginosa. Whereas 93% of untreated control animals died after a subsequent IP infection, vaccinated animals developed an efficient protection. The mortality rate in orally pretreated animals was only 20% - 30%. Some immunological parameters were also improved by vaccination. IgG and IgM concentrations in serum increased, as did the agglutination titer against bacteria. Oral vaccination with heat inactivated pathogenic bacteria seems to be a promising procedure to improve the resistance of patients to bacterial infections.
Integrating Hidden Markov Models and Spectral Analysis for Sensory Time Series Clustering (2006)

We present a novel approach for clustering sequences of multi-dimensional trajectory data obtained from a sensor network. The sensory time-series data present new challenges to data mining, including uneven sequence lengths, multi-dimensionality and high levels of noise. We adopt a principled approach, by first transforming all the data into an equal-length vector form while keeping as much temporal information as we can, and then applying dimensionality and noise reduction techniques such as spectral clustering to the transformed data. Experimental evaluation on synthetic and real data shows that our proposed approach outperforms standard model-based clustering algorithms for time series data.
An RNA‐Guided Cas9 Nickase‐Based Method for Universal Isothermal DNA Amplification (2019)

We have developed an ingenious method, termed Cas9 nickase-based amplification reaction (Cas9nAR), to amplify a target fragment from genomic DNA at a constant temperature of 37 °C. Cas9nAR employs a sgRNA:Cas9n complex with a single-strand nicking property, a strand-displacing DNA polymerase, and two primers bearing the cleavage sequence of Cas9n, to promote cycles of DNA replication through priming, extension, nicking, and displacement reaction steps. Cas9nAR exhibits a zeptomolar limit of detection (2 copies in 20 μL of reaction system) within 60 min and a single-base discrimination capability. More importantly, the underlying principle of Cas9nAR offers simplicity in primer design and universality in application. Considering the superior sensitivity and specificity, as well as the simple-to-implement, rapid, and isothermal features, Cas9nAR holds great potential to become a routine assay for the quantitative detection of nucleic acids in basic and applied studies.
Accurate Eye Diagram Prediction Based on Step Response and Its Aication to Low-Power Equalizer Design (2009)

This paper introduces a step response based method to predict the eye diagram for high-speed signaling systems. The method is able to predict accurately the worst-case eye diagram, and is orders of magnitude faster than the method using SPICE simulation with input of random bits. The proposed method is applied to search optimal equalizer parameters for lower-power transmission-line signaling schemes. Simulation results show that the scheme with driver-side series capacitor achieves much better eye area, and signaling throughput than the conventional scheme with only resistive terminations.
New Dyes and their Intermediates for Synthetic‐polymer Fibres (1969)

Halogenobenzothiazolylazo dyes were prepared by coupling diazotised halogeno‐2‐aminobenzothiazoles to N ‐β‐hydroxyethyl‐ N ‐β‐cyanoethyl‐ m ‐toluidine. The colour and fastness properties of the dyes on secondary cellulose acetate and on polyester fibre are compared with respect to the position and the nature of the halogen atom. Dyes containing 4‐halogeno atoms have the highest fastness to sublimation on polyester fibres; the fastness to light of the dyes is considerably higher on secondary cellulose acetate than on polyester fibres, but differences between individual dyes are small.
Inflation pressure requirements during coronary angioplasty (1990)

To examine the balloon inflation pressures required for successful percutaneous transluminal coronary angioplasty (PTCA), the maximal inflation pressure required for 477 coronary lesions in 200 consecutive patients was determined retrospectively. When graded balloon inflations just sufficient to achieve full expansion were used, the maximal inflation pressure used was less than or equal to 8 atm in 412 stenoses (86%) and was less than or equal to 10 atm in 463 stenoses (97%). Successful PTCA was achieved in 98% of lesions with a 3.5% major procedural complication rate. In a second group of 100 patients studied prospectively, the inflation pressure required to achieve full balloon expansion was less than or equal to 8 atm in 214 of 232 stenoses (92%) and less than or equal to 10 atm in 228 stenoses (98%). Thus, PTCA of coronary stenoses can be achieved with high success rates and low complication rates when graded inflations to pressures just sufficient to achieve full balloon expansion are performed. Most coronary stenoses will respond to pressures less than or equal to 8-10 atm.
The Preparation and Synthetic Utility of <i>tert</i>-Butyldiphenylsilyl Ethers (1975)

The utility of tert-butyldiphenylsilyl chloride as a reagent for the protection of hydroxyl groups was explored. The corresponding tert-BDPSi ethers have much greater stability to acids, and under conditions of hydrogenolysis, than related silyl and trityl ethers. Preferential removal of trityl, tetrahydropyranyl, benzyl, and other silyl ethers and acetals can be effected in presence of tert-EDPSi ethers. Treatment with fluoride ion causes smooth cleavage of the latter.
Ambulatory care visits of physician offices, hospital outpatient departments, and emergency departments: United States, 1995. (1997)

During 1995 an estimated 860.9 million visits were made to physician offices, hospital outpatient departments, and hospital emergency departments in the United States, an overall rate of 3.3 visits per person. Visits to office-based physicians accounted for 81.0 percent of ambulatory care utilization, followed by visits to emergency departments (11.2 percent) and outpatient departments (7.8 percent). Persons 75 years and over had the highest rate of ambulatory care visits. Females had significantly higher rates of visits to physician offices and hospital outpatient departments than males did. Less than two-thirds of ambulatory care visits by black persons were to physician offices. There were an estimated 126.1 million injury-related ambulatory care visits during 1995, or 48.2 visits per 100 persons.
An Experiment in Non-Linear Prediction (1965)

The role of statistics in numerical weather prediction should be to aid in the handling of random errors and disturbances. The actual prediction is a problem in dynamics. When the initial conditions are observed with error, there is information in the past forecasts which could increase the accuracy of the numerical predictions. The techniques of control theory provide an optimal method for combining past forecasts with current observations. This paper demonstrates the method on simulated non-linear time series.
Overproduction of NFKB2 (lyt-10) and c-Rel: a mechanism for HTLV-I Tax-mediated trans-activation via the NF-kappa B signalling pathway. (1994)

Molecular, biochemical and epidemiological evidence implicate HTLV-I as an etiologic agent of adult T cell leukemia (ATL). The Tax protein of HTLV-I, a positive transcriptional activator of HTLV-I gene expression, is a viral oncogene that also increases transcription of cellular genes including GM-CSF, IL-2R alpha and IL-2. One of the cellular targets of the trans-activating effects of Tax is the NF-kappa B/Rel family of transcription factors, pleiotropic regulators of immunoregulatory, cytokine and viral gene expression. In this report, we demonstrate that NFKB2 (lyt-10) and c-Rel are overexpressed in HTLV-I infected and Tax-expressing cells and, together, account for the majority of the constitutive NF-kappa B binding activity in these cells before and after PMA stimulation. Most importantly, we show a Tax-dependent correlation between expression of NFKB2(p100) and processing to the DNA binding NFKB2(p52) form, induction of c-Rel, and trans-activation of NF-kappa B-mediated gene expression. Furthermore, the NFKB2 precursor is physically associated with c-Rel and with Tax in HTLV-I infected cells. We propose that NFKB2 synthesis and processing allows continuous nuclear expression of an otherwise cytoplasmic protein and, in conjunction with overexpression of c-Rel, NFKB2 alters the NF-kappa B signalling pathway and contributes to leukemic transformation of T cells by HTLV-I.
Nonmuscle myosin heavy chain IIA mediates Epstein–Barr virus infection of nasopharyngeal epithelial cells (2015)

EBV causes B lymphomas and undifferentiated nasopharyngeal carcinoma (NPC). Although the mechanisms by which EBV infects B lymphocytes have been extensively studied, investigation of the mechanisms by which EBV infects nasopharyngeal epithelial cells (NPECs) has only recently been enabled by the successful growth of B lymphoma Mo-MLV insertion region 1 homolog (BMI1)-immortalized NPECs in vitro and the discovery that neuropilin 1 expression positively affects EBV glycoprotein B (gB)-mediated infection and tyrosine kinase activations in enhancing EBV infection of BMI1-immortalized NPECs. We have now found that even though EBV infected NPECs grown as a monolayer at extremely low efficiency (<3%), close to 30% of NPECs grown as sphere-like cells (SLCs) were infected by EBV. We also identified nonmuscle myosin heavy chain IIA (NMHC-IIA) as another NPEC protein important for efficient EBV infection. EBV gH/gL specifically interacted with NMHC-IIA both in vitro and in vivo. NMHC-IIA densely aggregated on the surface of NPEC SLCs and colocalized with EBV. EBV infection of NPEC SLCs was significantly reduced by NMHC-IIA siRNA knock-down. NMHC-IIA antisera also efficiently blocked EBV infection. These data indicate that NMHC-IIA is an important factor for EBV NPEC infection.
Using Abstraction to Interleave Planning and Execution (1997)

Abstraction is a technology that enables interleaved planning and execution, the much sought-after quality of a robot architecture that can both plan and act (and plan and act and plan...) in short order. This paper presents a definition for Abstraction and for an architecture composed of a collection of abstractions, or an Abstraction System. We span both the theoretical extreme of formally defining abstraction and the empirical extreme of implementing an Abstraction System on a real-world robot and collecting compelling experimental results.
The Effect of Cognitive Intervention on Cognitive Improvement in Patients with Dementia (2018)

These findings suggest that cognitive intervention might be useful for patients with dementia. Their response to treatment might be related to the type of intervention.
Laser-induced breakdown spectroscopy applications for metal-labeled biomolecule detection in paper assays (2020)

This doctoral thesis investigates the application of laser-induced breakdown spectroscopy (LIBS) for detection of labeled biomolecules on nitrocellulose paper. Nitrocellulose paper is a material often used for assays involving the concentration and labeling of a target analyte, followed by label detection. Among paper-based diagnostics are lateral-flow immuno-assays (LFIAs). Research efforts have made LFIAs into accessible, portable,and low-cost tools for detecting targets such as allergens, toxins,and microbes in food and water.Gold (Au) nanoparticles are standard biomolecular labels among LFIAs, typically detected via colorimetric means.Other labels, such as quantum dots, are also often metallic, and research is ongoing to expand the number of portable instrumentations applied to their detection. A wide diversity of lanthanide-complexed polymers (LCPs) are used as immunoassay labels but have been inapt for portable paper-based assays owing to lab-bound detection instrumentation, until now. LIBS is a multi-element characterization technique which has recently developed from a bench-top to a portable/hand-held analytical tool. This is among the first studies to show that LCPs can be considered as options for biomolecule labels in paper-based assays using bench-based and hand-held LIBS as label detection modalities.Chapter one reviews the importance of rapid, multiplexed detection of chemical and biological contaminants, the application of current biosensors, and the role of LIBS as an emerging biosensor. Paper-based bioassays were identified as a promising approach for contaminant detection whose capabilities could be enhanced by LIBS. The next chapter dives into LIBS system designs to address which LIBS parameters were appropriate for label detection on paper assay material. A balance of LIBS parameters was found to be important for successful analyte detection. Chaptert hree optimizes a LIBS design for sensitive detection of 17 metals and establishes limit of detection values for 7 metals. Optimal detection parameters depended on the metal being detected and were applied to the objective of the final chapter: LIBS detection of labeled antigen immobilized on a paper-based assay. Both antibody and bacteria detection assays were successfully performed and analyzed using bench top and portable LIBS,suggesting an exciting future for the use of LIBS as a biosensor.The prospect of using LIBS for multiplexed, rapid and sensitive detection of biomolecules in assays is explored, laying grounds for future work in the ever-relevant field of biological and chemical hazard detection.<br>

Multicast routing and bandwidth dimensioning in overlay networks (2002)

Multicast services can be provided either as a basic network service or as an application-layer service. Higher level multicast implementations often provide more sophisticated features and can provide multicast services at places where no network layer support is available. Overlay multicast networks offer an intermediate option, potentially combining the flexibility and advanced features of application layer multicast with the greater efficiency of network layer multicast. In this paper, we introduce the multicast routing problem specific to the overlay network environment and the related capacity assignment problem for overlay network planning. Our main contributions are the design of several routing algorithms that optimize the end-to-end delay and the interface bandwidth usage at the multicast service nodes within the overlay network. The interface bandwidth is typically a key resource for an overlay network provider, and needs to be carefully managed in order to maximize the number of users that can be served. Through simulations, we evaluate the performance of these algorithms under various traffic conditions and on various network topologies. The results show that our approach is cost-effective and robust under traffic variations.
