Medium-density WDM system with Fabry-Perot laser diodes for subscriber loop applications (1991)

Medium-density wavelength division multiplexing (WDM) systems with approximately four to eight wavelengths can provide an evolution path from near-term fiber-to-the-curb systems to a broadband passive optical network. The authors demonstrate that multilongitudinal-mode Fabry-Perot laser diodes can be used in such a system, with four 622 Mb/s channels in the 1.3- mu m window. This may provide a lower-cost alternative to the use of DFB lasers for such applications. Despite a channel spacing of only 15 nm, significant wavelength misalignments of the laser diodes relative to the WDM passbands can be tolerated before filter-induced mode-partition-noise penalties are observed. The potential for extending the data rate to 1.25 Gb/s is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tissue fibronectin is an endogenous ligand for galectin-1 (1995)

A 14K beta-galactoside-binding lectin (galectin-1) is present in many animal tissues. In a search for endogenous ligands, we surveyed galectin-1-binding proteins in human placenta. Extract of human placenta with 2 M urea was applied to a Sepharose 4B column conjugated with galectin-1 purified from frog (Rana catesbeiana) eggs. Two major proteins eluted with 100 mM lactose from the column-bound fraction showed apparent molecular masses of 220 and 180 kDa on SDS-PAGE under reducing conditions. Western blotting analysis using monoclonal antibodies indicated that these proteins were fibronectin and laminin, respectively. Most placental and amniotic fibronectins bound strongly to the column, whereas almost all plasma fibronectin passed through the column. The galectin-1, fibronectin and laminin were immunohistochemically shown to be co-localized in the extracellular matrix of placental tissue. In a cell attachment assay, rhabdosarcoma cells adhered to a plate coated with placental fibronectin, even in the presence of GRGDS peptide, if galectin-1 were also present. This adhesive effect of galectin-1 was inhibited by lactose. These results indicate that tissue fibronectin, as well as laminin, serve as endogenous ligands for galectin-1, suggesting that galectin-1 may play a role in assembly of the extracellular matrix, or in the control of cell adhesion based on lectin-extracellular matrix interaction.
Characterization of the Essential Transport Function of the AIDA-I Autotransporter and Evidence Supporting Structural Predictions (1999)

The current model for autodisplay suggests a mechanism that allows a passenger protein to be translocated across the outer membrane by coordinate action of a C-terminal beta-barrel and its preceding linking region. The passenger protein, linker, and beta-barrel are together termed the autotransporter, while the linker and beta-barrel are here referred to as the translocation unit (TU). We characterized the minimal TU necessary for autodisplay with the adhesin-involved-in-diffuse-adherence (AIDA-I) autotransporter. The assumed beta-barrel structure at the C terminus of the AIDA-I autotransporter was studied by constructing a set of seven AIDA-I-cholera toxin B subunit fusion proteins containing various portions of AIDA-I. Surface exposure of the cholera toxin B moiety was assessed by dot blot experiments and trypsin accessibility of the chimeric proteins expressed in Escherichia coli JK321 or UT5600. Export of cholera toxin B strictly depended on a complete predicted beta-barrel region. The absolute necessity for export of a linking region and its influence on expression as an integral part of the TU was also demonstrated. The different electrophoretic mobilities of native and denatured chimeras indicated that the proposed beta-barrel resides within the C-terminal 312 amino acids of AIDA-I. Together these data provide evidence for the predicted beta-barrel structure and support our formerly proposed model of membrane topology of the AIDA-I autotransporter.
New mathematical model for the correct prediction of the exchangeable blood volume during acute normovolemic hemodilution (2002)

Exchangeable blood volume is predicted more accurately by the new iterative model than by the Bourke and Smith formula. The iterative model leads to an improvement in patient safety and provides a physiologically adequate basis for future studies investigating the efficacy of ANH in reducing allogenic blood transfusions.

Nonlinear order preserving index for encrypted database query in service cloud environments (2013)

SUMMARY The database services on cloud are appearing as an attractive way of outsourcing databases. When a database is deployed on a cloud database service, the data security and privacy becomes a big concern for users. A straightforward way to address this concern is to encrypt the database. However, after encryption, the database cannot be easily queried. In this paper, we propose a nonlinear order preserving scheme for indexing encrypted data, which facilitates the range queries over encrypted databases. The scheme is secure even there are a large number of duplicates in plaintexts. Moreover, our scheme allows the programmability of basic indexing expressions and thus provides the capability of hiding the distribution of plaintexts from the distribution of indexes. This scheme is suitable for long‐standing databases because its use does not need any assumption on the characteristics of database data, such as their distribution, range and number, which may change dramatically over time.Copyright © 2013 John Wiley & Sons, Ltd.
Addressable Arrays Implemented with One Metal Level for MOSFET and Resistor Variability Characterization (2009)

Addressable array test structures for rapid collection of statistical distributions of MOSFET parameters and parasitic resistances are described. A unique feature of these designs is that they require only one level of metal, yet are compact for placement in the scribe line for early process learning. MOSFET measurements are made over full range of I-V characteristics including leakage currents of individual devices in the sub-threshold region. A modular approach for test structure integration and parallel testability enables high efficiency in design and data acquisition.
Fiber laser based wavelength division multiplexed fiber bragg grating sensor system (2002)

A fiber laser-based wavelength division multiplexed sensor system with five fiber bragg grating sensor array as reflector of a ring-cavity fiber laser has been demonstrated experimently. A tunable F-P filter inside the cavity was used to interrogate the sensors and establish the laser formation. Wavelength-shift signal induced by the measured strain was demodulated by an unbalanced Michelson scanning interferometer. The sensitivity of the system was demonstrated to be 1.669°/με which was in agreement with the theoretical value of 1.678°/με well. The system was also designed to track one of the channels automatically with a feedback subsystem.
Immunochemical Approaches for Purification and Detection of TNT Traces by Antibodies Entrapped in a Sol−Gel Matrix (2001)

A highly sensitive immunochemical method for immunoaffinity purification (IAP) and detection of trace amounts of TNT was developed on the basis of antibodies (Abs) in a ceramic matrix (sol-gel). The study resulted in: (i) a highly sensitive and reproducible TNT ELISA (I50 and I20 values of 0.4 +/- 0.09 ppb and 0.12 +/- 0.03 ppb, respectively; n = 12), which is highly specific to TNT; and (ii) successful entrapment of the Abs that bound free analyte from solution. Binding was found to be highly reproducible, dose dependent, and only slightly (1.2-1.8-fold) lower than that in solution. The entrapped Abs did not leach from the matrix and were tolerant of absolute ethanol, acetone, and acetonitrile. Bound analytes could be easily eluted from the sol-gel matrix at high recoveries. The sol-gel-based IAP method described above introduces a simple one-step procedure that has a high potential to serve as a suitable and convenient immunochromatographic device for cleanup and concentration of TNT from "real field" samples in a manner that complies with both chemical and immunochemical residue analysis methods.

Cytocompatible Poly(ethylene glycol)‐<i>co</i>‐polycarbonate Hydrogels Cross‐Linked by Copper‐Free, Strain‐Promoted Click Chemistry (2011)

Strategies to encapsulate cells in cytocompatible three-dimensional hydrogels with tunable mechanical properties and degradability without harmful gelling conditions are highly desired for regenerative medicine applications. Here we reported a method for preparing poly(ethylene glycol)-co-polycarbonate hydrogels through copper-free, strain-promoted azide-alkyne cycloaddition (SPAAC) click chemistry. Hydrogels with varying mechanical properties were formed by "clicking" azido-functionalized poly(ethylene glycol)-co-polycarbonate macromers with dibenzocyclooctyne-functionalized poly(ethylene glycol) under physiological conditions within minutes. Bone marrow stromal cells encapsulated in these gels exhibited higher cellular viability than those encapsulated in photo-cross-linked poly(ethylene glycol) dimethacrylate. The precise control over the macromer compositions, cytocompatible SPAAC cross-linking, and the degradability of the polycarbonate segments make these hydrogels promising candidates for scaffold and stem cell assisted tissue repair and regeneration.
eIF2B is a decameric guanine nucleotide exchange factor with a γ2ε2 tetrameric core (2014)

eIF2B facilitates and controls protein synthesis in eukaryotes by mediating guanine nucleotide exchange on its partner eIF2. We combined mass spectrometry (MS) with chemical cross-linking, surface accessibility measurements and homology modelling to define subunit stoichiometry and interactions within eIF2B and eIF2. Although it is generally accepted that eIF2B is a pentamer of five non-identical subunits (α-ε), here we show that eIF2B is a decamer. MS and cross-linking of eIF2B complexes allows us to propose a model for the subunit arrangements within eIF2B where the subunit assembly occurs through catalytic γ- and ε-subunits, with regulatory subunits arranged in asymmetric trimers associated with the core. Cross-links between eIF2 and eIF2B allow modelling of interactions that contribute to nucleotide exchange and its control by eIF2 phosphorylation. Finally, we identify that GTP binds to eIF2Bγ, prompting us to propose a multi-step mechanism for nucleotide exchange.
Broadband transmission Raman measurements using a field-widened spatial heterodyne Raman spectrometer with mosaic grating structure (2018)

A field-widened spatial heterodyne Raman spectrometer with a mosaic grating structure is developed for the simultaneous sensitivity enhancement and broadband transmission Raman measurements. We optimize the etendue to maximize the signals collected from the samples by using field-widening prisms and employ two mosaic gratings to achieve broadband operation, covering 5638 cm<sup>-1</sup> with 2.865 cm<sup>-1</sup> spectral resolution. The signal-to-noise ratios are improved by a factor of more than 11 and show a good stability and fair repeatability. We investigate the effects of the sample thickness and outer layer depth and observe liquids, solids, mixed targets, and anti-Stokes shifts. The instrument exhibits good performance for wide-field, high-resolution broadband transmission Raman measurements.
Analysis of Power Consumption in Future High-Capacity Network Nodes (2009)

Power consumption and the footprint of future network elements are expected to become the main limiting factors for scaling the current architectures and approaches to capacities of hundreds of terabits or even petabits per second. Since the underlying demand for network capacity can be satisfied only by contemporaneously increasing transmission bit rate, processing speed, and switching capacity, it unavoidably will lead to increased power consumption of network nodes. On the one hand, using optical switching fabrics could relax the limitations to some extent, but large optical buffers occupy larger areas and dissipate more power than electronic ones. On the other hand, electronic technology has made fast progress during the past decade regarding reduced feature size and decreased power consumption. It is expected that this trend will continue in the future. This paper addresses power consumption issues in future high-capacity switching and routing elements and examines different architectures based on both pure packet-switched and pure circuit-switched designs by assuming either all-electronic or all-optical implementation, which can be seen as upper and lower bounds regarding power consumption. The total power consumption of a realistic and appropriate technology for future high-performance core network nodes would probably lie somewhere between those two extreme cases. Our results show that implementation in optics is generally more power efficient; especially circuit-switched architectures have a low power consumption. When taking into account possible future developments of Si CMOS technology, even very large electronic packet routers having capacities of more than hundreds of terabits per second seem to be feasible. Because circuit switching is more power efficient and easier to implement in optics than pure packet switching, the scalability limitation due to increased power consumption could be considerably relaxed when a kind of dynamic optical circuit switching is used within the core network together with an efficient flow aggregation at edge nodes.
Design of a video-server complex for interactive television (1998)

This paper describes the architecture and implementation of a scalable video server for interactive television services, which has been used in several video-on-demand projects in Japan. This server supports a large number of users with the delivery of high-quality video and provides many types of interactive multimedia applications. The server, using the IBM RISC System/6000® and RISC System/6000 Scalable POWERparallel Systems®, permits full interactive operation with clients. It also can deliver a large number of streams when it is expanded from a single-processor system to a multi-processor system, without any change of the server architecture. In this paper, we describe the end-to-end architecture, the design considerations regarding scalability of the delivery scheme for MPEG-2 transport streams, and the management mechanism for interactive applications. This paper also addresses the implementation of quality of service for digital services through a hybrid fiber-coax network infrastructure, and protocols for interactive television services.
Hydrogels for Pharmaceutical and Biomedical Applications (2005)

Hydrogels are crosslinked hydrophilic polymer structures that can imbibe large amounts of water or biological fluids. Hydrogels are one of the upcoming classes of polymer-based systems that embrace numerous biomedical and pharmaceutical applications. This review discusses various parameters of hydrogels such as surface properties, water content and swelling behavior, effect of nature of polymer, ionic content, and thermodynamics, all of which can influence the biomedical usage of hydrogels. Meanwhile, intelligent or environment-sensitive hydrogels and bioadhesive hydrogels continue to be important materials for medical applications; therefore, a part of this review is devoted to some of their important classes. Hydrogels are extensively used for various biomedical applications--tissue engineering, molecular imprinting, wound dressings materials, immunoisolation, drug delivery, etc. Thus, this review aims to throw light on the numerous applications that hydrogels have in the biomedical arena.
Suppression of cogongrass (<i>Imperata cylindrica</i>) by a bioherbicidal fungus and plant competition (2004)

The possibility of using the fungus Bipolaris sacchari as a bioherbicide to suppress cogongrass and to allow the establishment of bahiagrass in cogongrass–bahiagrass mixed plantings was investigated under greenhouse conditions. The bioherbicide was prepared by mixing B. sacchari spore suspension containing 10 5 spores ml −1 with an oil emulsion composed of 16% horticultural oil plus 10% light mineral oil and 74% sterile water. The bioherbicide caused severe foliar blight in cogongrass and slight phytotoxic damage on bahiagrass. In the first experiment, the bioherbicide reduced cogongrass biomass without affecting bahiagrass biomass. In the second experiment, the bioherbicide caused a 64% reduction in fresh weight, a 74% reduction in the number of rhizomes, and a 47% reduction in the height of cogongrass. The latter experiment also showed an increase in bahiagrass fresh weight in the presence of cogongrass when the bioherbicide was applied. This study indicates the potential of combining bioherbicide application with competition from a desirable grass species as a strategy for the integrated management of cogongrass.

Development of High Superconductor Fraction ${\hbox{Bi}}_{2}{\hbox{ Sr}}_{2}{\hbox{CaCu}}_{2}{\hbox{O}}_{\rm x}/{\hbox{Ag}}$ Wire for MRI (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Bi2212 round multifilament wire has good potential for MRI systems designed to operate at 20 K and produce fields greater than 1.5 T. However, Bi2212 conductor is expensive largely due to the costs associated with materials and fabrication. To reduce the cost, we are investigating single restack designs. This approach reduces the silver fraction. It also reduces the amount of processing needed to make the conductor. However, a single restack limits the minimum filament diameter that can be achieved since the strain space is more limited. In this work we evaluated 4 conductor configurations to determine the effects of fill-factor, filament diameter, and s/d on <formula formulatype="inline"> <tex>${\rm J}_{\rm e}$</tex></formula> and n value. It was found that a reduction in filament size has a greater effect on <formula formulatype="inline"><tex>${\rm J}_{\rm e}$</tex></formula> and n value than a corresponding increase in fill-factor. Some guidelines for optimization of conductor design are developed. </para>
Modelling and analysis of spread spectrum signalling with multiple receivers for distributed wireless in-building networks (2002)

The authors present the model and performance analysis of a distributed wireless-in-building network (DWIBN) employing slotted Aloha multiaccess with direct-sequence spread-spectrum (DS/SS) signaling and multiple receivers to combat multipath and multiaccess interference and the near-far effect. The system is shown to offer high throughput capacity. Under overload traffic, the system is capable of maintaining a high throughput without significant increase in delays. The effectiveness of using multiple receivers to increase the channel throughput, decrease the packet waiting time, and minimize the near-far effect, especially under high packet input rate, is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Enhancement of Arsenic Trioxide-Mediated Changes in Human Induced Pluripotent Stem Cells (IPS) (2014)

Induced pluripotent stem cells (IPS) are an artificially derived type of pluripotent stem cell, showing many of the same characteristics as natural pluripotent stem cells. IPS are a hopeful therapeutic model; however there is a critical need to determine their response to environmental toxins. Effects of arsenic on cells have been studied extensively; however, its effect on IPS is yet to be elucidated. Arsenic trioxide (ATO) has been shown to inhibit cell proliferation, induce apoptosis and genotoxicity in many cells. Based on ATOs action in other cells, we hypothesize that it will induce alterations in morphology, inhibit cell viability and induce a genotoxic effect on IPS. Cells were treated for 24 hours with ATO (0-9 µg/mL). Cell morphology, viability and DNA damage were documented. Results indicated sufficient changes in morphology of cell colonies mainly in cell ability to maintain grouping and ability to remain adherent. Cell viability decreased in a dose dependent manner. There were significant increases in tail length and moment as well as destruction of intact DNA as concentration increased. Exposure to ATO resulted in a reproducible dose dependent sequence of events marked by changes in morphology, decrease of cell viability, and induction of genotoxicity in IPS.
Recent Development of Solid Oxide Fuel Cells in Japan (1999)

The R&D activities on solid oxide fuel cells in Japan are summarized with emphases on the national projects, industrial efforts and university activities. The important feature of fabrication technology in Japan is the success in utilizing wet processes by three major groups of developers. TOTO, Kyushu Electric Co. and Nippon Steel have succeeded in testing 1 kW module of tubular SOFCs. Mitsubishi Heavy Industries and Chubu Electric Co. have completed a test of 5 kW module of planar SOFCs with a high power density and high efficiency. Mitsubishi Heavy Industries and Electric Power Development Co. have tested 1 kW module of tubular SOFCs made with a new interconnect material by a wet process, in addition to testing a pressurized 10 kW module made by plasma spray. These successes make it technologically and economically feasible to fabricate SOFCs by wet processes on a mass production scale. Activities on development of alternative materials/processing/design have been also active. Electrotechnical Laboratory has proposed the tubular SOFC on metallic substrates. National Institute of Materials and Chemical Research has proposed small non-reforming SOFCs for methane with high efficiency and the utilization of electrophoretic deposition technique for small tubular cells. Toho Gas has proposed a honeycomb type design. Emphases should be placed also on the development of LaGaO3-based electrolyte, one-chamber fuel cells, and membrane reactors for producing CO+H2 gas from methane.
