Morphology of OLED Film Stacks Containing Solution-Processed Phosphorescent Dendrimers (2018)

Organic light-emitting devices containing solution-processed emissive dendrimers can be highly efficient. The most efficient devices contain a blend of the light-emitting dendrimer in a host and one or more charge-transporting layers. Using neutron reflectometry measurements with in situ photoluminescence, we have investigated the structure of the as-formed film as well as the changes in film structure and dendrimer emission under thermal stress. It was found that the as-formed film stacks comprising poly(3,4-ethylenedioxythiophene):polystyrene sulfonate/host:dendrimer/1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene (where the host was deuterated 4,4'-N,N'-di(carbazolyl)biphenyl or tris(4-carbazol-9-ylphenyl)amine, the host:dendrimer layer was solution-processed, and the 1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene evaporated) had well-defined interfaces, indicating good wetting of each of the layers by the subsequently deposited layer. Upon thermal annealing, there was no change in the poly(3,4-ethylenedioxythiophene):polystyrene sulfonate/host:dendrimer interface, but once the temperature reached above the T<sub>g</sub> of the host:dendrimer layer, it became a supercooled liquid into which 1,3,5-tris(N-phenylbenzimidazol-2-yl)benzene dissolved. When the film stacks were held at a temperature just above the onset of the diffusion process, they underwent an initial relatively fast diffusion process before reaching a quasi-stable state at that temperature.

Comparing NoC architectures for neural networks (2010)

Implementation of reconfigurable neural networks in hardware requires highly flexible connectivity, creating major architectural challenge. We perform an analytical evaluation and comparison of different configurable interconnect architectures (mesh NoC, tree, shared bus and point-to-point) emulating variants of two neural network topologies (having full and random exponential configurable connectivity). We derive analytical expressions and asymptotic limits for performance (in terms of bandwidth) and cost (in terms of area and power) of the interconnect architectures considering three communication methods (unicast, multicast and broadcast). It is shown that planar structure, fault and drop tolerance and pulse-information encoding in spiking neural networks makes simple multicast mesh network-on-chip suitable for massively parallel communication required by these networks. Simulation results successfully validate the analytical models and the asymptotic behavior of the network as a function of its size.

Avian Flu School: A Training Approach to Prepare for H5N1 Highly Pathogenic Avian Influenza (2008)

Since the reemergence of highly pathogenic avian influenza (H5N1 HPAI) in 2003, a panzootic that is historically unprecedented in the number of infected flocks, geographic spread, and economic consequences for agriculture has developed. The epidemic has affected a wide range of birds and mammals, including humans. The ineffective management of outbreaks, mainly due to a lack of knowledge among those involved in detection, prevention, and response, points to the need for training on H5N1 HPAI. The main challenges are the multidisciplinary approach required, the lack of experts, the need to train at all levels, and the diversity of outbreak scenarios. Avian Flu School addresses these challenges through a three-level train-the-trainer program intended to minimize the health and economic impacts of H5N1 HPAI by improving a community's ability to prevent and respond, while protecting themselves and others. The course teaches need-to-know facts using highly flexible, interactive, and relevant materials.
<title>Matrix-assisted laser desorption by Fourier transform mass spectrometry</title> (1991)

Infrared and ultraviolet matrix-assisted laser desorption Fourier transform mass spectrometry is investigated using a number of different matrices. In common with previous reports, it is found that the most efficacious matrices, regardless of laser wavelength used, are those which absorb at the chosen wavelength. Effects of matrix/analyte ratio, laser power, and choice of matrix under low pressure Fourier transform mass spectrometry conditions are examined.
Self-consistent field, ab initio molecular orbital and three-dimensional reference interaction site model study for solvation effect on carbon monoxide in aqueous solution (2000)

We have developed a three-dimensional (3D) extension of the reference interaction site model-self-consistent field (RISM-SCF) method to treat the electronic structure of a solvated molecule. The site–site treatment of the solute–solvent correlations involving the approximation of radial averaging constitutes a bottleneck of the RISM-SCF method, and thus lacks a 3D picture of the solvation structure for complex solutes. To resolve this problem, we devised out a 3D generalization of the RISM integral equations which yields the 3D correlation functions of interaction sites of solvent molecules around a solute of arbitrary shape. In the present article, we propose a SCF combination of the ab initio molecular orbital (MO) methods and 3D-RISM approach. A benchmark result for carbon monoxide in ambient water is also presented.
Effects of plasma surface modification on interfacial behaviors and mechanical properties of carbon nanotube-Al2O3 nanocomposites (2007)

The effects of plasma surface modification on interfacial behaviors in carbon nanotube (CNT) reinforced alumina (Al2O3) nanocomposites were studied. A unique plasma polymerization method was used to modify the surfaces of CNTs and Al2O3 nanoparticles. The CNT-Al2O3 nanocomposites were processed by both ambient pressure and hot-press sintering. The electron microscopy results showed ultrathin polymer coating on the surfaces of CNTs and Al2O3 nanoparticles. A distinctive stress-strain curve difference related to the structural interfaces and plasma coating was observed from the nanocomposites. The mechanical performance and thermal stability of CNT-Al2O3 nanocomposites were found to be significantly enhanced by the plasma-polymerized coating.
A Compact Absorbing FSS Structure for Antenna Decoupling in the 5G 3.5GHz Band (2020)

Antenna decoupling has gained a large interest in the last years, especially for MIMO 5G communications. In this frame, a high isolation is required between the multiple antennas of a transmitting array of a base station while preserving the specified radiation pattern and the compactness of the antenna array. Different solutions were proposed in the literature to provide decoupling performance. Among these, the absorbing frequency selective surface (FSS) structures have shown interesting properties. In this paper, a new type of compact FSS is introduced, using composite material technology and screenprinting. It takes advantage of a specific geometrical pattern that lowers its operation frequency with a similar spatial periodicity. We provide simulations of its absorbing properties together with an experimental validation of its performance. The proposed absorbing structure will be further adapted to decouple patch antennas in composite material technology.

Francisella philomiragia comb. nov. (formerly Yersinia philomiragia) and Francisella tularensis biogroup novicida (formerly Francisella novicida) associated with human disease (1989)

Over a 12-year period, 16 human strains of a gram-negative, catalase-positive, halophilic, aerobic, nonmotile, small coccoid bacterium were received for identification. On the bases of biochemical characteristics and cellular fatty acid profiles, 14 of these strains were similar to the "Philomiragia" bacterium (Yersinia philomiragia, species incertae sedis). Additional characteristics were growth on Thayer-Martin agar but no growth or sparse, delayed growth on MacConkey agar; oxidase positive; acid production, often weak and delayed, from D-glucose, sucrose, and maltose; urease negative; no reduction of nitrates; and H2S produced but often delayed in triple sugar iron agar. Both the human isolates and the "Philomiragia" bacterium contained C10:0, C14:0, C16:0, C18:1 omega 9c, C18:0, 3-OH C18:0, C22:0, and C24:1 as major cellular fatty acids and ubiquinone eight (Q8) as the major isoprenoid quinone. These cellular acids in these relative amounts have been found previously only in Francisella tularensis and Francisella novicida, suggesting a relationship between the "Philomiragia" bacterium and Francisella species. Of the 14 human "Philomiragia"-like isolates, 9 were from blood, 3 were from lung biopsies or pleural fluid, and one each was from peritoneal fluid and cerebrospinal fluid. DNA relatedness studies (hydroxyapatite method, 50 and 65 degrees C) showed that these 14 strains were a single group that was the same species as the "Philomiragia" bacterium. Two other human strains were oxidase negative and H2S negative. They formed a single DNA relatedness group that was indistinguishable from the type strains of both F. tularensis and F. novicida. DNA relatedness of "Philomiragia" bacterium type and other strains to strains of F. novicida and F. tularensis, including the type strains, was 35 to 46%. One of the two F. novicida- and F. tularensis-like strains was isolated from blood, and the other was isolated from a cervical lymph node. On the basis of these findings, we propose transferring Y. philomiragia from the genus Yersinia to the genus Francisella as Francisella philomiragia comb. nov. Having confirmed that F novicida and F. tularensis are the same species and having shown that F. novicida is pathogenic for humans, we further propose eliminating the species F. novicida and demoting it to a biogroup of F. tularensis.
Analyzing clickstreams using subsessions (2000)

Analyzing data obtained from web server logs, so-called "clickstreams", is rapidly becoming one of the most important activities for companies in any sector as most businesses become ebusinesses. Clickstream analysis can reveal usage patterns on the company's web site and give a highly improved understanding of customer behavior. This understanding can then be utilized for improving customer satisfaction with the web site and the company in general, yielding a huge business advantage.
Experimental Therapy of Mice Infected with Leishmania Tropica (1979)

The therapeutic effect of sodium stibogluconate, amphotericin B, and metronidazole was studied in an experimental Leishmania tropica infection in outbred white mice inoculated 28, 14, or 0 days previously in the nose and foot pad. The pentavalent antimony and amphotericin were administered subcutaneously for 14 days at doses of 400 mg/kg body weight a day and 12.5 mg/kg a day, respectively, whereas metronidazole was given orally for 14 days at a dose of 50 mg/kg a day. In a separate experiment, inbred BALB/c mice, infected in the foot pad, were treated with pentavalent antimony as before or with an 8-amino-quinoline compound (WR 6026) at a dose of 12 mg/kg a day. The lesions that developed were measured at regular intervals for 7–10 weeks. In outbred mice with established lesions of 4 weeks' duration, no effect of treatment was observed. In mice infected 2 weeks earlier, and especially in animals infected when treatment was started, sodium stibogluconate and amphotericin B prevented or delayed development of lesions during or after the period of treatment. However, soon after termination of treatment most animals showed rapidly growing lesions. Metronidazole had no effect on development of lesions. Results of treatment with sodium stibogluconate in BALB/c mice were similar to those observed with the outbred mice. The 8-amino-quinoline compound (WR 6026) showed only a questionably significant late effect on lesions in BALB/c mice. Viable parasites were cultured from representative mice of all treatment groups many weeks after termination of therapy. This mouse model for certain strains of Leishmania may be useful for experimental therapy studies.

Potato: Improving Crop Productivity and Abiotic Stress Tolerance (2012)

Potato is a prestige food crop that billions of people in the world depend on as an energy source. Its widespread cultivation and adaptation have rendered it attractive for humans of all cultures and geographic locations. However, its effective production is challenged by many unfavorable environmental conditions, such as drought, heat, cold, and salinity. Recent tools developed in genomic research have advanced our understanding of the potato crop in its ability to manage these stresses. This chapter provides the latest information on our understanding of stress tolerance mechanisms in potatoes based on functional genomics, transcriptomics, proteomics, and metabolomics studies. We also recommend many choices of functional genes that can be used for improving stress tolerance in potatoes. We would like to point out that due to lack of the completion of the potato genome sequence, many research projects are not able to provide more advanced systems biology data in comparison to that available for many other agricultural species.
Stochastic Block Models with Multiple Continuous Attributes (2018)

The stochastic block model (SBM) is a probabilistic model for community structure in networks. Typically, only the adjacency matrix is used to perform SBM parameter inference. In this paper, we consider circumstances in which nodes have an associated vector of continuous attributes that are also used to learn the node-to-community assignments and corresponding SBM parameters. While this assumption is not realistic for every application, our model assumes that the attributes associated with the nodes in a network's community can be described by a common multivariate Gaussian model. In this augmented, attributed SBM, the objective is to simultaneously learn the SBM connectivity probabilities with the multivariate Gaussian parameters describing each community. While there are recent examples in the literature that combine connectivity and attribute information to inform community detection, our model is the first augmented stochastic block model to handle multiple continuous attributes. This provides the flexibility in biological data to, for example, augment connectivity information with continuous measurements from multiple experimental modalities. Because the lack of labeled network data often makes community detection results difficult to validate, we highlight the usefulness of our model for two network prediction tasks: link prediction and collaborative filtering. As a result of fitting this attributed stochastic block model, one can predict the attribute vector or connectivity patterns for a new node in the event of the complementary source of information (connectivity or attributes, respectively). We also highlight two biological examples where the attributed stochastic block model provides satisfactory performance in the link prediction and collaborative filtering tasks.
Comparison of Predictions With Test Results for Rotordynamic Coefficients of a Four-Pocket Gas Damper Seal (1999)

Experiments and field applications have demonstrated that multiple-pocket gas damper seals effectively eliminate subsynchronous vibration and attenuate imbalance response at the critical speeds in turbomachinery. A one-control volume, turbulent bulk-flow model for the prediction of the seal leakage and rotordynamic force coefficients of centered multiple-pocket damper seals is hereby detailed. Comparisons of numerical predictions with experimental force coefficients for a four-pocket damper seal are presented. The bulk-flow model and experiments indicate the seal direct stiffness and damping force coefficients are insensitive to journal speed while the cross-coupled stiffnesses increase slightly. However, the current model overpredicts the direct damping coefficient and underpredicts the direct stiffness coefficient for increasing test pressure ratios. Computed results show that the force coefficients of multiple-pocket gas damper seals are also functions of the rotor excitation frequency.
Mirrored pyramidal wells for simultaneous multiple vantage point microscopy (2008)

We report a novel method for obtaining simultaneous images from multiple vantage points of a microscopic specimen using size-matched microscopic mirrors created from anisotropically etched silicon. The resulting pyramidal wells enable bright-field and fluorescent side-view images, and when combined with z-sectioning, provide additional information for 3D reconstructions of the specimen. We have demonstrated the 3D localization and tracking over time of the centrosome of a live Dictyostelium discoideum. The simultaneous acquisition of images from multiple perspectives also provides a five-fold increase in the theoretical collection efficiency of emitted photons, a property which may be useful for low-light imaging modalities such as bioluminescence, or low abundance surface-marker labelling.
Engineering of Targeted Nanoparticles for Cancer Therapy Using Internalizing Aptamers Isolated by Cell-Uptake Selection (2012)

One of the major challenges in the development of targeted nanoparticles (NPs) for cancer therapy is to discover targeting ligands that allow for differential binding and uptake by the target cancer cells. Using prostate cancer (PCa) as a model disease, we developed a cell-uptake selection strategy to isolate PCa-specific internalizing 2′-O-methyl RNA aptamers (Apts) for NP incorporation. Twelve cycles of selection and counter-selection were done to obtain a panel of internalizing Apts, which can distinguish PCa cells from nonprostate and normal prostate cells. After Apt characterization, size minimization, and conjugation of the Apts with fluorescently labeled polymeric NPs, the NP–Apt conjugates exhibit PCa specificity and enhancement in cellular uptake when compared to nontargeted NPs lacking the internalizing Apts. Furthermore, when docetaxel, a chemotherapeutic agent used for the treatment of PCa, was encapsulated within the NP–Apt, a significant improvement in cytotoxicity was achieved in targeted PCa cells. Rather than isolating high-affinity Apts as reported in previous selection processes, our selection strategy was designed to enrich cancer cell-specific internalizing Apts. A similar cell-uptake selection strategy may be used to develop specific internalizing ligands for a myriad of other diseases and can potentially facilitate delivering various molecules, including drugs and siRNAs, into target cells.
Production and composition of microbial fat from Rhodotorula glutinis (1984)

Abstract The fatty acid, sterol and hydrocarbon compositions of oil produced by a new strain of Rhodotorula glutinis isolated from soil and grown on molasses, were determined. The major constituent fatty acids were: palmitic (37%) oleic (47%) and linoleic (8%). The major sterols were campesterol (42%) and stigmasterol (27%) and the major hydrocarbons were n ‐C 23 (37%), iso ‐C 29 (30%) and n ‐C 21 (19%). Minor constituents in each class of lipids were also detected and estimated. The oil produced was 54% on a dry weight basis. The fatty acid composition was found to be close to that of palm oil.

Entanglement assisted time-energy QKD employing Franson interferometers and cavity quantum electrodynamics (CQED) principles (2015)

In this paper, we propose several entanglement assisted QKD protocols based on time-energy encoding with the number of mutually unbiased bases (MUBs) larger than two. We describe how to implement these protocols based on: (i) optical FFT device implemented in integrated optics with the help of Franson interferometers and (ii) Weyl gate. We also describe the corresponding weak-coherent state-based protocol. By employing the <i>N</i>-dimensional pulse position modulation (ND-PPM) approach, the secret key rate of single photon pulse per signaling interval protocols can be improved by <i>N/log<sub>2</sub>N</i> times. However, the corresponding entanglement assisted protocols require the use of cavity quantum electrodynamics (CQED) principles to further entangle single photon pulse per frame state. We then analyze the security of the proposed protocols and provide the finite secret key rates in the presence of various imperfections including background errors and timing jitter, for which we propose the <i>K</i>-neighbor model. Finally, we provide the improvements in secret key rates of proposed protocol over conventional two-base time-energy QKD protocol.
Denaturation of Type I Collagen Fibrils Is an Endothermic Process Accompanied by a Noticeable Change in the Partial Heat Capacity (1998)

Thermal transitions of type I collagen fibrils were investigated by differential scanning calorimetry and spectrophotometry of turbidity within a wide range of external conditions. The advanced microcalorimeter allowed us to carry out the measurements at low concentrations of collagen (0.15-0.3 mg/mL). At these concentrations of collagen and under fibril-forming conditions, the melting curves display two pronounced heat adsorption peaks (at 40 and 55 degreesC). The low-temperature peak was assigned to the melting of monomeric collagen, while the high-temperature peak was assigned to the denaturation of collagen fibrils. It was shown that the denaturation of fibrils, in contrast to the monomeric collagen, is accompanied by a noticeable change in the partial specific heat capacity. Surprisingly, comparison of the collagen calorimetric curves in the fibril-forming and nonforming conditions revealed that DeltaCp of fibril denaturation is caused by a decrease in the Cp of collagen at premelting temperatures. This suggests the existence of an intermediate structural state of collagen in a transparent solution preceding fibril formation. Our study also shows that collagen fibrils formed prior to heating have thermodynamic parameters different from those of fibrils formed and denatured during heating in the calorimeter. Analysis of the data allowed us to determine the denaturation enthalpy of the mature fibrils and to conclude that the enthalpy plays a more important role in fibril stabilization than was previously assumed. The observed large DeltaCp value of fibril denaturation as well as the difference between thermodynamic parameters of the mature and newly formed fibrils is readily explained by the presence of water molecules in the fibril structure.
Erhöhung der Reaktionsgeschwindigkeit bei der nucleophilen Alkylierung von Carbonylverbindungen durch ein neues Templat mit zwei Metallzentren (1998)

Zwei in die gleiche Richtung weisende Aluminiumzentren binden Carbonylgruppen so, daß ein effizienter Alkyltransfer vom Aluminium auf das α-C-Atom möglich ist. Dieser verläuft über einen günstigen sechsgliedrigen Übergangszustand (1). Dadurch lassen sich Carbonylverbindungen mit weniger reaktiven Alkylmetall-Verbindungen alkylieren.
