Shape-Controlled Anatase Titanium(IV) Oxide Particles Prepared by Hydrothermal Treatment of Peroxo Titanic Acid in the Presence of Polyvinyl Alcohol (2009)

Anatase titanium(IV) oxide (TiO2) particles with specific exposed crystal faces were prepared by hydrothermal treatment of peroxo titanic acid (PTA) solution with polyvinyl alcohol as a shape-control reagent. Crystal phase, shape, and size of TiO2 particles were found to be greatly dependent on pH value of PTA solution and time of hydrothermal treatment. TiO2 particles prepared from PTA solution of pH 7 had {101} and {001} exposed crystal faces, and the shape of TiO2 particles changed with the time of hydrothermal treatment. The prepared TiO2 particles with specific exposed crystal faces showed higher photocatalytic activity for acetaldehyde decomposition than commercial spherical TiO2 particles. This result implies that back reaction was prevented by spatial separation of redox sites in the particles because of selective migration of electrons and positive holes to specific exposed crystal faces and/or different reactivity of electrons and positive holes on the specific exposed crystal face. Furthermore, the shape evolution of TiO2 particles showed a relationship with photocatalytic activity, and a stacked structure of octahedral anatase showed the highest photocatalytic activity due to both oxidation and reduction sites with large surface area.
An all chemical solution deposition approach for the growth of highly textured CeO<sub>2</sub>cap layers on La<sub>2</sub>Zr<sub>2</sub>O<sub>7</sub>-buffered long lengths of biaxially textured Ni–W substrates for YBCO-coated conductors (2005)

A reel-to-reel, dip coating process has been developed to continuously deposit epitaxial La2Zr2O7 (LZO) and CeO2 on 5 m long cube-textured {100} (001)Ni tapes. Recent results for La2Zr2O7 and CeO2 buffer layers deposited on long lengths of Ni substrate for the realization of YBa2Cu3O7−x (YBCO)-coated conductors are presented. The major achievement is the development of a new all chemical solution deposition (CSD) process leading to the formation of highly textured buffer layers at moderate annealing temperatures. Reproducible highly textured, dense and crack-free LZO buffer layers and CeO2 cap layers were obtained for annealing temperatures as low as 900 °C in a reducing atmosphere (Ar–5 at.%-H2). The thickness of the LZO buffer layers was determined to be (200 ± 10) nm per single coating; prepared cerium oxide layers showed a thickness of 60 nm ± 10 nm. Pulsed laser deposition (PLD) was used to grow YBCO films on these substrates. A Tc 0 of T = 90.5 K and ΔTc = 1.4 K was obtained on PLD-YBCO/CSD-CeO2 /CSD-LZO/Ni–5 at.% W, which shows the outstanding features of this new buffer layer architecture processed by CSD. The large layer thickness combined with low annealing temperatures is the main advantage of this new process for low-cost buffer layer deposition on Ni-RABiTS (rolling-assisted biaxially textured substrates).
Tumor‐specific CD8+ T lymphocytes derived from the peripheral blood of prostate cancer patients by <i>in vitro</i> stimulation with autologous tumor cell lines (2001)

To identify tumor-associated antigens as putative targets for developing immunotherapies against prostate cancer, we investigated the ability of T cells derived from the peripheral blood lymphocytes of prostate cancer patients to recognize autologous tumor cells. The technical challenge of growing in vitro carcinoma cell lines from small prostate cancer samples was previously addressed by immortalization of early epithelial cell cultures with the HPV16 transforming proteins E6 and E7 and by genetic characterization of the carcinoma and normal prostate cell lines. In our study, peripheral blood lymphocytes were stimulated in vitro using autologous IFNgamma-treated prostate carcinoma cells transduced with the B7.1 molecule as a source of T-cell costimulation. Tumor-specific CD8+ T lymphocytes were obtained from 3 of 6 prostate cancer patients tested and included T cells restricted by classical and nonclassical HLA molecules. In 1 case, we demonstrated that the prostate cancer-reactive T cells were TCRalpha/beta+ and recognized autologous tumor cells but not autologous normal cells in the context of HLA-B or -C molecules. These results validate the approach of in vitro stimulation of peripheral blood lymphocytes from prostate cancer patients with autologous tumor cell lines to isolate prostate cancer-specific T cells and demonstrate the existence of a functionally diverse immune response against prostate cancer.
Wireless Emergency Alerts: Trust Model Technical Report (2014)

Trust is a key factor in the effectiveness of the Wireless Emergency Alerts (WEA) service. Alert originators (AOs) must trust WEA to deliver alerts to the public in an accurate and timely manner. Members of the public must also trust the WEA service before they will act on the alerts that they receive. This research aimed to develop a trust model to enable the Federal Emergency Management Agency (FEMA) to maximize the effectiveness of WEA and provide guidance for AOs that would support them in using WEA in a manner that maximizes public safety. The research method included Bayesian belief networks to model trust in WEA because they enable reasoning about and modeling of uncertainty. The research approach was to build models that could predict the levels of AO trust and public trust in specific scenarios, validate these models using data collected from AOs and the public, and execute simulations on these models for numerous scenarios to identify recommendations to AOs and FEMA for actions to take that increase trust and actions to avoid that decrease trust. This report describes the process used to develop and validate the trust models and the resulting structure and functionality of the models.
Towards the development of a universal T cell influenza (FLU) vaccine (52.10) (2010)

Abstract Present day FLU vaccines have not changed since WWII, and depend upon the generation of neutralizing antibodies, which the virus readily escapes via mutations. Therefore, we focused on immunizing T cells with serologically non-cross reactive viral strains in a murine model. C57Bl/6 mice infected intra-nasally (i.n.) with H3N2-FLU were protected against a lethal challenge of H1N1-FLU. Cellular composition of the Broncho-Alveolar Lavage (BAL), lungs and mediastinal lymph nodes monitored by flow-cytometry 8 days after infection with H1N1-FLU yielded a vigorous cellular response, with a 2:1 ratio of CD8+ vs. CD4+ T cells in the BAL, and a high proportion of immunodominant nucleoprotein (NP) peptide-specific tetramer+ cells (~ 40%). By comparison, mice immunized i.n. with replication-incompetent adenovirus containing NP (10e7 pfu) were also protected against lethal challenge. Although the H3N2-FLU-infected control animals mobilized greater numbers of CD8+ T cells in the BAL 14d post H1N1 challenge, the vaccinated animals had 3X as many NP-specific tetramer+ T cells. Therefore, a non-replicating adenovirus vaccine can protect against a lethal challenge with a non-serologically cross-reactive flu strain, so that a “T cell vaccine” is effective in preventing symptomatic disease.
Resonance Stabilized Perfluorinated Ionomers for Alkaline Membrane Fuel Cells (2013)

Perfluorosulfonic acids such as Nafion are industrial standard cation exchange ionomers for polymer electrolyte membrane fuel cells because of their high gas permeability, hydrophobicity, and inertness to electro-chemical reaction. In this research, pentamethylguanidinium functionalized, perfluorinated hydroxide conducting ionomers for alkaline membrane fuel cells were prepared and characterized. The alkaline stability of the ionomers largely depended on the adjacent group that connected the cation; Sulfone guanidinium functionalized ionomer degraded almost completely after soaking in 0.5 M NaOH at 80 °C for 24 h, while phenylguanidinium functionalized ionomer did not degrade under the same conditions for 72 h. Spectroscopic data and density functional theory calculation suggested that the stability of the phenylguanidinium ionomer was greatly improved by charge delocalization of the formed resonance structure. Alkaline membrane fuel cells using the resonance stabilized perfluorinated ionomer in the catalyst layers on quaternized polyphenylene membrane showed excellent performance (ca. maximum power density = 466 mW/cm2) and promising stability (ca. Tafel slope degradation rate = 225 μV/dec h) at 80 °C under H2/air conditions.
Study of nickel electrode oxidation as a function of 80% depth of discharge cycling (2002)

Oxidation of nickel sinter used in nickel oxide electrodes in aerospace Ni-Cd secondary cells leads to hydrogen gassing and the potential for cell rupture. The oxidation is directly related to loss of overcharge protection built into the cell during manufacturing. In Ni-H/sub 2/ cells, excessive oxidation of the nickel sinter can eventually lead to a burst before leak situation and is a potential source of failure. It is well known that Ni-Cd cells having nylon separators contribute to loss of overcharge via a hydrolysis reaction of the nylon in the potassium hydroxide electrolyte environment in the cell. The hydrolysis reaction produces lower chain organics which are oxidized by the positive electrode and oxygen. Oxidation of the organics diminishes the overcharge protection. With introduction of the Super NiCd/sup TM/ and the Magnum/sup TM/ Ni-Cd cells, the nylon hydrolysis reaction is eliminated, but any reducing agent in the cell such as nickel or an organic additive can contribute to loss of overcharge protection. The present effort describes chemical analyses made to evaluate the extent of overcharge protection loss in Ni-Cd cells which do not have nylon hydrolysis, and quantifies the amount of hydrogen buildup in Ni-H/sub 2/ cells which are subjected to 80% depth of discharge cycling with and without the presence of cadmium in the positive electrode.
Phenotypic variability associated with 14 splice‐site mutations in the NF2 Gene (1998)

Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder caused by mutations in the NF2 gene. Patients carrying NF2 mutations are predisposed to cerebral and spinal tumors with bilateral vestibular schwannomas as the hallmark. Using single strand conformation polymorphism and temperature gradient gel electrophoresis analysis, we have screened 87 unrelated NF2 patients for mutations in the NF2 gene. In this study, we report phenotypes associated with 14 splice-site mutations carried by 14 propositi and 11 relatives. The mutations were distributed in exons 2, 3, 5, 7, 8, 14, and 15. These splice-site mutations were associated with various phenotypes, from severe to asymptomatic. Phenotypic variation was also observed within families. Mutations downstream from exon 8 resulted more often in mild phenotypes. No meningiomas were found in any of 13 affected or mutation bearing individuals from three families with splice-site mutations of exons 14 and 15. These data suggest that splice-site alteration is a relatively common cause of NF2, and that unlike other mutations the clinical outcomes of splice-site mutations in the NF2 gene are variable. These results add to the growing body of information on genotype–phenotype correlation in NF2. Am. J. Med. Genet. 77:228–233, 1998. © 1998 Wiley-Liss, Inc.
Structurally Stable Attractive Nanoscale Emulsions with Dipole–Dipole Interaction‐Driven Interdrop Percolation (2017)

This study introduces an extremely stable attractive nanoscale emulsion fluid, in which the amphiphilic block copolymer, poly(ethylene oxide)-block-poly(ϵ-caprolactone) (PEO-b-PCL), is tightly packed with lecithin, thereby forming a mechanically robust thin-film at the oil-water interface. The molecular association of PEO-b-PCL with lecithin is critical for formation of a tighter and denser molecular assembly at the interface, which is systematically confirmed by T<sub>2</sub> relaxation and DSC analyses. Moreover, suspension rheology studies also reflect the interdroplet attractions over a wide volume fraction range of the dispersed oil phase; this results in a percolated network of stable drops that exhibit no signs of coalescence or phase separation. This unique rheological behavior is attributed to the dipolar interaction between the phosphorylcholine groups of lecithin and the methoxy end groups of PEO-b-PCL. Finally, the nanoemulsion system significantly enhances transdermal delivery efficiency due to its favorable attraction to the skin, as well as high diffusivity of the nanoscale emulsion drops.
AUTONOMOUS OPERATIONS THROUGH ONBOARD ARTIFICIAL INTELLIGENCE (2002)

The Autonomous Sciencecraft Experiment (ASE) will fly onboard the Air Force TechSat 21 constellation of three spacecraft scheduled for launch in 2006. ASE uses onboard continuous planning, robust task and goal-based execution, model-based mode identification and reconfiguration, and onboard machine learning and pattern recognition to radically increase science return by enabling intelligent downlink selection and autonomous retargeting. Demonstration of these capabilities in a flight environment will open up tremendous new opportunities in planetary science, space physics, and earth science that would be unreachable without this technology.
Polymers with pendant isocyanate groups. III. Synthesis and properties of poly(styrene‐co‐acrylonitrile‐co‐styrylisocyanate) (1979)

Abstract The terpolymer poly(styrene‐co‐acrylonitrile‐co‐styrylisocyanate) was synthesized by radical initiation directly from styrene, acrylonitrile, and cinnamoyl azide. The monomer feed–terpolymer composition relationship was determined by Slocombe's triangular graph. The solubility, intrinsic viscosity, and melting range of the various terpolymers and the chemical reactions of the pendant isocyanate groups toward alcohol and amines were investigated.
Theory of strong down-conversion in multi-mode cavity and circuit QED (2022)

We revisit the superstrong coupling regime of multi-mode cavity quantum electrodynamics (QED), defined to occur when the frequency of vacuum Rabi oscillations between the qubit and the nearest cavity mode exceeds the cavity's free spectral range. A novel prediction is made that the cavity's linear spectrum, measured in the vanishing power limit, can acquire an intricate fine structure associated with the qubit-induced cascades of coherent single-photon down-conversion processes. This many-body effect is hard to capture by a brute-force numerics and it is sensitive to the light-matter coupling parameters both in the infra-red and the ultra-violet limits. We focused at the example case of a superconducting fluxonium qubit coupled to a long transmission line section. The conversion rate in such a circuit QED setup can readily exceed a few MHz, which is plenty to overcome the usual decoherence processes. Analytical calculations were made possible by an unconventional gauge choice, in which the qubit circuit interacts with radiation via the flux/charge variable in the low-/high-frequency limits, respectively. Our prediction of the fine spectral structure lays the foundation for the "strong down-conversion" regime in quantum optics, in which a single photon excited in a non-linear medium spontaneously down-converts faster than it is absorbed.
Web Spoofing Techniques, Implementation and Solutions. (2004)

The concept of combining electrical impedance spectroscopy (EIS) with environmental transmission electron microscopy (ETEM) is demonstrated by testing a specially designed micro gadolinia-doped ceria (CGO) sample in reactive gasses (O<sub>2</sub> and H<sub>2</sub> /H<sub>2</sub> O), at elevated temperatures (room temperature-800 °C) and with applied electrical potentials. The EIS-TEM method provides structural and compositional information with direct correlation to the electrochemical performance. It is demonstrated that reliable EIS measurements can be achieved in the TEM for a sample with nanoscale dimensions. Specifically, the ionic and electronic conductivity, the surface exchange resistivity, and the volume-specific chemical capacitance are in good agreement with results from more standardized electrochemical tests on macroscopic samples. CGO is chosen as a test material due to its relevance for solid oxide electrochemical reactions where its electrochemical performance depends on temperature and gas environment. As expected, the results show increased conductivity and lower surface exchange resistance in H<sub>2</sub> /H<sub>2</sub> O gas mixtures where the oxygen partial pressure is low compared to experiments in pure O<sub>2</sub> . The developed EIS-TEM platform is an important tool in promoting the understanding of nanoscale processes for green energy technologies, e.g., solid oxide electrolysis/fuel cells, batteries, thermoelectric devices, etc.
A Study of the Survival and Oxygen Deficiency at the Zebra Mussel (Dreissena polymorpha) Treated with Zinc (Zn) (2009)

The current paper studies the change of respiratory rate and survival of Dreissena polymorpha at short exposure to zinc under laboratory conditions. The experiment is lasted 96h and three different concentrations of ZnSO4.7H2O were used - 0.5mg/l, 1.5mg/l; 2,0 mg/l. Survival and intensity of breathing of Dreissena polymorpha decreases with the increasing concentration of zinc in the water.
Room-Temperature, Tunable Gain Media from Novel II–VI Nanocrystal–Titania Composite Matrices (2002)

Semiconductor nanocrystals embedded in a titania matrix (see Figure for an AFM image) at volume fractions high enough to observe amplified spontaneous emission (ASE) have been prepared. ASE has been observed at room temperature for these structures and at multiple wavelengths, thus promising a wide range of tunable, room-temperature lasers and other nonlinear optics applications.
The decrease of ‘‘random telegraph signal’’ noise in metal-oxide-semiconductor field-effect transistors when cycled from inversion to accumulation (1992)

The low-frequency (LF) noise behavior of metal-oxide-semiconductor field-effect transistors (MOSFETs) is studied when cycled between inversion and accumulation. On large-area devices the decrease of the LF noise is systematically found, and supports the observations by Bloom and Nemirovsky [Appl. Phys. Lett. 58, 1664 (1991)]. The random telegraph signal (RTS) noise observed in small (submicrometer) devices disappears when the transistor is cycled into accumulation. The drop in LF noise observed may thus be explained by the fact that most or all of the RTSs, which are caused by carrier trapping into slow oxide states, no longer contribute to the noise of the system. The method indicates a possibility to separate the contributions of different sources of 1/f noise in MOSFETs.
Functional test of the influence of <i>Wolbachia</i> genes on cytoplasmic incompatibility expression in <i>Drosophila melanogaster</i> (2010)

Wolbachia are inherited intracellular bacteria that infect a broad range of invertebrate hosts. They commonly manipulate host reproduction in a variety of ways and thereby favour their invasion into host populations. While the biology of Wolbachia has been extensively studied at the ecological and phenotypic level, little is known about the molecular mechanisms underlying the interaction between Wolbachia and their hosts. Recent comparative genomics studies of Wolbachia strains have revealed putative candidate genes involved in the expression of cytoplasmic incompatibility (CI) in insects. However the functional testing of these genes is hindered by the lack of available genetic tools in Wolbachia. To circumvent this problem we generated transgenic Drosophila lines expressing various Wolbachia CI candidate genes under the control of the GAL4/UAS system in order to evaluate their possible role in Wolbachia-related phenotypes in Drosophila. The expression of a number of these genes in Drosophila melanogaster failed to mimic or alter CI phenotypes across a range of Wolbachia backgrounds or in the absence of Wolbachia.
Modelling and Simulation in Health Care Technology – from Development via Implementation to Assessment (2010)

Modelling and Simulation (M&S) has found its way into many areas, almost in our daily life, so also into health technology (HT). Health technology and medical technology encompass a wide range of health care products and services -from vaccination strategies to heart circulation monitoring. And they are used to diagnose, monitor or treat every disease or condition that affects humans. M&S in HT is improving the quality of health care delivered and patient outcomes through earlier diagnosis, less invasive treatment and reductions of illness. This contribution investigates M&S in HT at different levels: (i) M&S for developing a HT product, (ii) M&S implemented in a HT product, and (iii) M&S for assessment of a HT product. While the step from model-based development of HT products to model-based operation of HT products is evident, the last step to model-based assessment of HT products is relatively new application of M&S -and necessary for the success of HT products. Interestingly, although the aims of M&S at these three levels differ significantly, the M&S techniques -from Markov models via ODEs/PDEs to Agent-based models stay the same.
