Keyword and phrase spotting by use of the Harpy speech system (1978)

Two problems of a keyword spotting system that are not encountered in isolated work recognition systems are the detection of the beginning and ending of the words within the context of other words and the phenomena that occur at the word junctures. A modification of the Harpy connected speech recognition system has yielded a word and phrase spotting system that deals with these problems. This word spotting system incorporates the lexical and word juncture knowledge and uses a modified beam search technique of the Harpy system. This enables the system to not only rapidly and accurately spot single words within any context but also multiple words and/or complex phrases. Performance results of the system will be presented for various words and phrases and for different threshold values.
UV-Vis spectrophotometry of quinone flow battery electrolyte for <i>in situ</i> monitoring and improved electrochemical modeling of potential and quinhydrone formation (2017)

Quinone-based aqueous flow batteries provide a potential opportunity for large-scale, low-cost energy storage due to their composition from earth abundant elements, high aqueous solubility, reversible redox kinetics and their chemical tunability such as reduction potential. In an operating flow battery utilizing 9,10-anthraquinone-2,7-disulfonic acid, the aggregation of an oxidized quinone and a reduced hydroquinone to form a quinhydrone dimer causes significant variations from ideal solution behavior and of optical absorption from the Beer-Lambert law. We utilize in situ UV-Vis spectrophotometry to establish (a), quinone, hydroquinone and quinhydrone molar attenuation profiles and (b), an equilibrium constant for formation of the quinhydrone dimer (K<sub>QHQ</sub>) ∼ 80 M<sup>-1</sup>. We use the molar optical attenuation profiles to identify the total molecular concentration and state of charge at arbitrary mixtures of quinone and hydroquinone. We report density functional theory calculations to support the quinhydrone UV-Vis measurements and to provide insight into the dimerization conformations. We instrument a quinone-bromine flow battery with a Pd-H reference electrode in order to demonstrate how complexation in both the negative (quinone) and positive (bromine) electrolytes directly impacts measured half-cell and full-cell voltages. This work shows how accounting for electrolyte complexation improves the accuracy of electrochemical modeling of flow battery electrolytes.
Self-Heating Synthesis of Materials (1991)

Many solid-state chemical reactions are accompanied by the evolution of heat (I). The amount of heat evolved varies over a wide range (e.g. 300 to 1200 cal gI) and is determined by the chemical system. In conventional methods used to synthesize inorganic materials, the reactants are usually heated in furnaces at high temperatures for periods of time ranging from a few minutes to many hours. The rate of heating to a selected temperature is purposely kept low to reduce the possibility of extensive overheating caused by the heat of reaction. It is somewhat ironic then that new, energy-efficient methods are being developed to synthesize and consolidate inorganic materials into a final product by utilizing the chemical energy of the reactants. If a chemical reaction is sufficiently exothermic, thcn a mixture of pow­ dered reactants, either in a crucible or formed into a free-standing shape, may be ignited by a hot thermal source. From the point of ignition, a combustion wave rapidly self-propagates through the reactants, converting

<i>Xanthomonas</i> AvrBs3 Family-Type III Effectors: Discovery and Function (2010)

Xanthomonads are bacterial plant pathogens that cause diseases on many plant species, including important crops. Key to pathogenicity of most Xanthomonas pathovars is a Hrp-type III secretion (T3S) system that translocates effector proteins into plant cells. Within the eukaryotic cell, the effectors are thought to perform a variety of tasks to support bacterial virulence, proliferation, and dissemination. We are only beginning to understand the host targets of different effectors. The largest effector family found in Xanthomonas spp. is the AvrBs3/PthA or TAL (transcription activator-like) family. TAL effectors act as transcriptional activators in the plant cell nucleus. Specificity of TAL effectors is determined by a novel modular DNA-binding domain. Here, we describe the discovery of TAL effectors and their structure, activity, and host targets.
Teleoperation Support for Early Human Planetary Missions (2005)

A renewed interest in human exploration is flourishing among all the major spacefaring nations. In fact, in the complex scene of planned future space activities, the development of a Moon base and the human exploration of Mars might have the potential to renew the enthusiasm in expanding the human presence beyond the boundaries of Earth. Various initiatives have been undertaken to define scenarios and identify the required infrastructures and related technology innovations. The typical proposed approach follows a multistep strategy, starting with a series of precursor robotic missions to acquire further knowledge of the planet and to select the best potential landing sites, and evolving toward more demanding missions for the development of a surface infrastructure necessary to sustain human presence. The technologies involved in such a demanding enterprise range from typical space technologies, like transportation and propulsion, automation and robotics, rendezvous and docking, entry/reentry, aero-braking, navigation, and deep space communications, to human-specific issues like physiology, psychology, behavioral aspects, and nutritional science for long-duration exposure, that go beyond the traditional boundaries of space activities. Among the required elements to support planetary exploration, both for the precursor robotic missions and to sustain human exploration, rovers and trucks play a key role. A robust level of autonomy will need to be secured to perform preplanned operations, particularly for the surface infrastructure development, and a teleoperated support, either from Earth or from a local base, will enhance the in situ field exploration capability.
Fractal Growth Patterns in Liquid Crystals (2001)

Bent-core mesogens, the ”banana liquid crystals”, represent a fascinating, novel class of materials with suprising physical properties. During the phase-ordering process of the liquid crystal from its isotropic melt, fractal growth patterns form (see the picture, in which such a crystal phase, in black, is nucleated from an air bubble, central circle). The fractal growth patterns are qualitatively different from the growth patterns observed for ordinary rodlike liquid crystal molecules.

CAMPATH 1-H INDUCTION THERAPY IN KIDNEY TRANSPLANTATION: 2 YEAR RESULTS (2004)

O141* Aims: To determine the effect of Campath 1-H induction therapy compared to basiliximab on outcomes of kidney transplant recipients followed for 2 years. Methods: This is a single-center, retrospective study. The Campath 1-H [n=123 (cads 31, LD 92)] and basiliximab [n=155 (cads 58, LD 97)] cohorts were sequentially treated groups. The demographics of the groups were similar. The mean±SD follow-up time for the Campath group was 21.8±4.7 mo. (tx dates: 10/01-9/02) and the basiliximab group was 45.8±10.0 mo. (tx dates: 9/98-9/01). The induction dose of Campath was 30 mg as a single dose intra-operatively, and Basiliximab 20 mg days 0 and 2. All kidney transplant recipients received a prednisone-free maintenance immunosuppression protocol of tacrolimus and MMF. Patient and graft survival and rejection rates were determined by Kaplan-Meier life table analysis. Rejections were biopsy-proven. Results: The table below shows the pertinent results. There were no statistically significant differences between groups in 2-year patient and graft survival rates. The 1-year rejection rates were similar, however, the mean time to rejection in the first year was significantly earlier in the basiliximab group (33.4 d.) vs Campath (116 d). Throughout the 2-year follow-up interval the Campath recipients consistently required less MMF immunosuppression. Important viral and fungal infectious disease occurred in 10% of Campath recipients and 15% of basiliximab recipients. One PTLD occurred in each group.FigureStatistical analysis: ap=0.10; bp=0.15; cp=0.52; dp<0.001. Conclusions: This series is the largest long-term experience with Campath in kidney transplantation. The 2-year patient and graft survival results using Campath in a prednisone-free maintenance protocol compared favourably with basiliximab. The advantages of Campath were: it prevented very early rejection, a lower dose of maintenance MMF was required, a slight decrease in important infectious complications was observed, and it was less costly than basiliximab. Campath is a safe and effective induction agent for kidney transplant recipients.
Characterizing piezoceramic material using complex frequency excitation (2002)

This paper discusses a new technique to characterize lossy piezoelectric materials. This new method uses a complex frequency to stimulate a resonator's true resonant point. Parameters that are acquired from the characterization are the material attenuation constant, the impedance at the resonant frequency, an equivalent resistance for circuit modeling and an acoustic viscosity. Knowledge of this information can be very useful to circuit designers and material manufacturers. A nice feature of this technique is that it is easily implemented using and arbitrary waveform generator, a PC with data analysis/acquisition software and an oscilloscope.
<i>LACCASE</i> Is Necessary and Nonredundant with <i>PEROXIDASE</i> for Lignin Polymerization during Vascular Development in <i>Arabidopsis</i>    (2013)

The evolution of lignin biosynthesis was critical in the transition of plants from an aquatic to an upright terrestrial lifestyle. Lignin is assembled by oxidative polymerization of two major monomers, coniferyl alcohol and sinapyl alcohol. Although two recently discovered laccases, LAC4 and LAC17, have been shown to play a role in lignin polymerization in Arabidopsis thaliana, disruption of both genes only leads to a relatively small change in lignin content and only under continuous illumination. Simultaneous disruption of LAC11 along with LAC4 and LAC17 causes severe plant growth arrest, narrower root diameter, indehiscent anthers, and vascular development arrest with lack of lignification. Genome-wide transcript analysis revealed that all the putative lignin peroxidase genes are expressed at normal levels or even higher in the laccase triple mutant, suggesting that lignin laccase activity is necessary and nonredundant with peroxidase activity for monolignol polymerization during plant vascular development. Interestingly, even though lignin deposition in roots is almost completely abolished in the lac11 lac4 lac17 triple mutant, the Casparian strip, which is lignified through the activity of peroxidase, is still functional. Phylogenetic analysis revealed that lignin laccase genes have no orthologs in lower plant species, suggesting that the monolignol laccase genes diverged after the evolution of seed plants.
The Wfirst Exoplanet Microlensing Survey (2018)

The Wide Field Infrared Survey Telescope (WFIRST) is a NASA space observatory designed to address key questions about the Universe and the population of extrasolar planets in our Galaxy. WFIRST is planned for launch in the mid-2020s. One of the main WFIRST science program is a statistical census of exoplanets with a microlensing survey, using about one quarter of the overall observing time. Specifically, the microlensing campaign is expected to be sensitive to detect low-mass planets at orbital separation greater than about 1 AU and to free-floating planets down to the mass of Mars. I am going to introduce the science case of microlensing exoplanets and the WFIRST mission. I will describe the expected yield of the WFIRST microlensing survey and I will report on the main outcomes of some of the current observational programs preliminary to the WFIRST mission. Finally, I will outline the possible role of the VST during the WFIRST microlensing survey.
Tri-scan: a novel DFT technique for CMOS path delay fault testing (2005)

We propose a novel design for testability technique to apply two pattern tests for path delay fault testing. Due to stringent timing requirements of deep-submicron VLSI chips, design-for-test schemes have to be tailored for detecting stuck-at as well as delay faults quickly and efficiently. Existing techniques such as enhanced scan add substantial hardware overhead, whereas techniques such as scan-shifting or functional justification make the test generation process complex and produce lower coverage for scan based designs as compared to non-scan designs. We exploit the characteristics of CMOS circuitry to enable the application of two-pattern tests. The proposed technique reduces the problem of path delay fault testing for scan based designs to that of path delay fault testing with complete accessibility to the combinational logic, and has minimal area overhead. The scheme also provides significant reduction in power during scan operation.
Modelling The Fire Performance of Structural Timber-Concrete Composite Floors (2014)

This paper describes numerical modelling to predict the fire resistance of engineered timber-concrete composite floor systems. The paper describes 3D numerical modelling of the floor systems using finite element software, carried out as a sequential thermo-mechanical analysis. Experimental testing of these floor assemblies has also been undertaken to validate the models, with multiple full scale tests conducted to determine the failure mechanisms and assess fire damage to the system components. The final outcome of this research is the development of simplified design methods for calculating the fire resistance of a wide range of engineered timber floor systems, as part of a larger research project on multi-storey timber buildings.
Four Loci Explain 83% of Size Variation in the Horse (2012)

Horse body size varies greatly due to intense selection within each breed. American Miniatures are less than one meter tall at the withers while Shires and Percherons can exceed two meters. The genetic basis for this variation is not known. We hypothesize that the breed population structure of the horse should simplify efforts to identify genes controlling size. In support of this, here we show with genome-wide association scans (GWAS) that genetic variation at just four loci can explain the great majority of horse size variation. Unlike humans, which are naturally reproducing and possess many genetic variants with weak effects on size, we show that horses, like other domestic mammals, carry just a small number of size loci with alleles of large effect. Furthermore, three of our horse size loci contain the LCORL, HMGA2 and ZFAT genes that have previously been found to control human height. The LCORL/NCAPG locus is also implicated in cattle growth and HMGA2 is associated with dog size. Extreme size diversification is a hallmark of domestication. Our results in the horse, complemented by the prior work in cattle and dog, serve to pinpoint those very few genes that have played major roles in the rapid evolution of size during domestication.
High-Throughput Microplate-Based Assay to Monitor Plasma Membrane Wounding and Repair (2017)

The plasma membrane of mammalian cells is susceptible to disruption by mechanical and biochemical damages that frequently occur within tissues. Therefore, efficient and rapid repair of the plasma membrane is essential for maintaining cellular homeostasis and survival. Excessive damage of the plasma membrane and defects in its repair are associated with pathological conditions such as infections, muscular dystrophy, heart failure, diabetes, and lung and neurodegenerative diseases. The molecular events that remodel the plasma membrane during its repair remain poorly understood. In the present work, we report the development of a quantitative high-throughput assay that monitors the efficiency of the plasma membrane repair in real time using a sensitive microplate reader. In this assay, the plasma membrane of living cells is perforated by the bacterial pore-forming toxin listeriolysin O and the integrity and recovery of the membrane are monitored at 37°C by measuring the fluorescence intensity of the membrane impermeant dye propidium iodide. We demonstrate that listeriolysin O causes dose-dependent plasma membrane wounding and activation of the cell repair machinery. This assay was successfully applied to cell types from different origins including epithelial and muscle cells. In conclusion, this high-throughput assay provides a novel opportunity for the discovery of membrane repair effectors and the development of new therapeutic compounds that could target membrane repair in various pathological processes, from degenerative to infectious diseases.
A methodology for rapid prototyping of real-time image processing VLSI systems (2002)

A methodology aimed at prototyping real-time image processing VLSI systems is presented. The prototyping methodology includes the emulation of the application in its target environment (i.e., in real time and on real-world scenes) and the automatic derivation of a VLSI chip-set implementing the application. Our methodology is based on a custom emulator called the Data-Flow Functional Computer (DFFC) which is dedicated to real-time image processing. Our method encompasses in a coherent environment: the validation of the high level specification; the simultaneous validation of an implementation of the design suitable for integration; and a method for integrating the validated emulator architecture as a VLSI system. The results of the successful prototyping of a defect detector algorithm are presented.

Exact and approximate probing of sea-bottom (2003)

Investigated are two methods for the reconstruction of the acoustic profiles of a plane-stratified structure that model the ocean floor (sediment/subbottom) from reflected fields. The first method is based on a geometrical acoustics approximation. The acoustical parameters of an absorbing layered medium (fluid-solid) are retrieved from the plane-wave reflection coefficients obtained at several incidences and frequencies. Numerical simulations are carried out for two typical configurations; one with high contrasts of parameters and the other with lower contrasts. The second method has initially been developed by S. Coen (1981) for lossless fluid media. The continuous inverse-scattering problem is transferred into the quantum-mechanics domain and solved by a Gel'fand-Levitan technique. Interesting results are obtained for various lossy fluid media and noisy data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Green Processing of a Cationic Polyelectrolyte Nanofibers in the Presence of Poly(vinyl alcohol) (2011)

ABSTRACT Aqueous electrospinning of polyelectrolyte polymers such as poly (diallyldimethylammonium chloride) (PDADMAC), which was not spinnable as such, was achieved by blending it with poly(vinyl alcohol) polymer. As the concentration of PDADMAC increased, the resulting blend solution was spinnable only after adjusting the solution behavior and electrospinning parameters. These nanofibers were cross-linked by heat treatment to make them water insoluble for applications. The average diameters of the nanofiber blends were reduced (118 ± 30 nm) when compared to PVA (151 ± 24 nm). These nanofibers could have potential applications in areas such as tissue regeneration scaffolds and controlled drug delivery.

Design and Fabrication of CLIC Test Structures (2008)

Demonstration of an accelerating gradient of 100 MV/m at a breakdown rate of 10 is one of the key feasibility issues of the CLIC study. A high power RF test program both at X-band (SLAC and KEK) and 30 GHz (CERN) is under way to develop accelerating structures which reach this performance. The centrepiece of the testing program is the nominal CLIC accelerating structure [1], but also includes structures with different RF parameters, with and without wakefield damping waveguides and made with different fabrication technologies. The latter structures address as directly as possible the different aspects of the nominal CLIC structure. The design and objectives of the various Xband and 30 GHz test structures are presented and their fabrication methods and status are reviewed.
