N-Best List Reranking using Higher Level Phonetic, Lexical, Syntactic and Semantic Knowledge Sources (2006)

This paper presents a novel methodology to improve large vocabulary continuous speech recognizer (LVCSR) hypotheses using additional phonetic, lexical, syntactic and semantic knowledge. Such additional higher level knowledge sources are unavailable during the LVCSR decoding due to the various constraints placed on the successful deployment of such information sources. This paper focuses on the extraction of WER improvements from the LVCSR n-best list using the additional higher level knowledge sources as the nucleus of a reranking mechanism. We illustrate the improvements obtained for the conversational speech transcription task and also for the directed dialog speech utterance transcription task in a grammar tuning application
Crystallization of zirconia based thin films (2015)

The crystallization kinetics of amorphous 3 and 8 mol% yttria stabilized zirconia (3YSZ and 8YSZ) thin films grown by pulsed laser deposition (PLD), spray pyrolysis and dc-magnetron sputtering are explored. The deposited films were heat treated up to 1000 °C ex situ and in situ in an X-ray diffractometer. A minimum temperature of 275 °C was determined at which as-deposited amorphous PLD grown 3YSZ films fully crystallize within five hours. Above 325 °C these films transform nearly instantaneously with a high degree of micro-strain when crystallized below 500 °C. In these films the t'' phase crystallizes which transforms at T > 600 °C to the t' phase upon relaxation of the micro-strain. Furthermore, the crystallization of 8YSZ thin films grown by PLD, spray pyrolysis and dc-sputtering are characterized by in situ XRD measurements. At a constant heating rate of 2.4 K min(-1) crystallization is accomplished after reaching 800 °C, while PLD grown thin films were completely crystallized already at ca. 300 °C.
Experiments on the synthesis of tetracycline. Part XIII. Oxidation of ring A model phenols to p-hydroxycyclohexadienones (1975)

The reaction of phenols with cerium(IV) oxide–hydrogen peroxide to give hydroperoxycyclohexadienones is described. In particular 2,6-dihydroxy-3,4-dimethylbenzamide (V) is converted into 3-hydroperoxy-2-hydroxy-3,4-dimethyl-6-oxocyclohexa-1,4-dienecarboxamide (VII). The reagent system is shown to be an in situ source of singlet oxygen.
ETA II experiments for determining advanced radiographic capabilities of induction linacs (2002)

LLNL has proposed a multi-pulsed, multi-line of sight radiographic machine based on induction linac technology to be the core of the advanced hydrotest facility (AHF) being considered by the Department of Energy. In order to test the new technologies being developed for AHF we have recommissioned the Experimental Test Accelerator (ETA II). We will conduct our initial experiments using kickers and large angle bending optics at the ETA II facility. Our current status and our proposed experimental schedule are presented.
Influence of hot water extraction on the physical and mechanical behavior of OSB (2008)

This study evaluated the influence of hot water extraction on hemicellulose removal, the concomitant change in wood properties, and finally production of oriented strandboard (OSB) from the modified wood. Three red maple (Acer rubrum L.) trees were felled, debarked, and their butt logs used to produce strands of 4-in length with a target thickness of either 0.025 inches, 0.035 inches, and 0.045 inches. Two hot water extraction procedures (320 °F, 90 psig) of 45 and 90 minutes duration (plus 50 minutes of preheating) were used, resulting in an average weight loss of 16.4 and 17.2 percent, respectively. Weight loss was significantly influenced by extraction time (p = 0.0011) and tree source (p = 0.0001) while the influence of strand thickness was not statistically significant (p = 0.1026). One OSB panel (17.6 inches by 12.4 inches by 0.5 inches) was manufactured for each of the 27 material combinations (2 extraction conditions and unextracted control, 3 trees, and 3 strand thickness). Panels were blended individually with a resin load of 3.2 percent pMDI resin, no wax, and an average density of 41.8 pcf (test volume basis). Physical and mechanical properties were determined following ASTM D1037-06 A procedures. Water absorption by OSB produced from both extraction treatments was significantly higher than the control for both 2 and 24 hours immersion while the thickness swell of panels from extracted material was slightly improved after 24 hours. The modulus of rupture (MOR) was not statistically significantly different between the control (5,966 psi) and the 45 minutes of extraction time (6,162 psi) panels, while the 90 minutes extraction time was significantly lower (4,093 psi). Internal bond strength in dry conditions from both extraction times (29 and 45 psi) were significantly lower than the control (117 psi), and similar results were obtained in wet condition (35 and 15 psi).
Gender Counts: Defining the Core Genetic Profile of Polycythemia Vera. (2004)

Abstract Intra-abdominal venous thrombosis and exuberant extramedullary hematopoiesis leading to painful splenomegaly and hepatomegaly are two of the most serious consequences of polycythemia vera. Although polycythemia vera is slightly more common in men, both of these complications appear to be more common in women, in whom the disease also presents at an earlier age. We previously reported that polycythemia vera peripheral blood (pb) CD34+ cells could be distinguished from their immunophenotypically similar normal counterparts by gene expression profiling. We, therefore, hypothesized that phenotypic differences in disease behavior between men and women with polycythemia vera were a consequence of gender-based genotypic differences and have employed gene expression profiling to examine this issue. For this purpose, cRNA was prepared from the total RNA of pb CD34+ cells of eleven polycythemia vera patients and six normal controls purified by immunomagnetic bead chromatography. The cRNA was hybridized to an Affymetrix HU133 high-density oligonucleotide microarray chip representing 22,000 genes. Approximately 30–45 % of chip genes were recorded as present in the RNA samples. GC-RMA (Robust Multiarray Analysis) was used for normalization, to adjust for probe effects and for signal estimation. A parametric empirical Bayes statistical modeling method was used for differential gene expression analysis between the patients and controls. A posterior probability of >0.5 was taken to indicate significant differential gene expression. As previously reported, all polycythemia vera patients could be unequivocally distinguished from the controls, indicating that gene expression profiling can be employed as diagnostic test for polycythemia vera. With respect to gender, comparing male patients with male controls, 1106 genes were differentially expressed in the patient group; comparing female patients with female controls, 461 genes were differentially expressed in the patient group. Using unsupervised hierarchical clustering, the control patients segregated as a single group while the polycythemia vera patients segregated into two groups based on exuberant extramedullary hematopoiesis but this segregation was not gender-based despite the marked differences in gender-specific gene expression. Importantly, however, after eliminating gender-specific genes, only 93 genes were concordantly expressed in the male and female patients (59 up regulated and 34 down regulated). This small group appears to represent core genes in polycythemia vera whose behavior may be modified by gender-specific genes but the specific up regulation or repression of which is essential for disease expression. These data indicate that gender-specific effects on gene expression must be addressed in order to determine the basic genetic signature of a hematologic malignancy and they also define a core genetic profile in polycythemia vera.

Wet gas scrubbing: State of the art in FCCU emission control (1987)

Abstract Particulates and SO 2 in Fluid Catalytic Cracking Unit (FCCU) flue gas can be controlled via wet gas scrubbing. Wet Gas Scrubbers (WGS) are compatible with the gaseous emission control devices such as CO boilers or High Temperature Regeneration (HTR) now in use on FCCU's and require no changes in FCCU operating procedures. Compared with a combination of particulate control with electrostatic precipitators and SO 2 control by FCCU feed desulfurization, WGS require less investment and have lower operating costs. Other advantages for WGS include higher service factor, smaller onsite plot space requirement, and simpler operation than electrostatic precipitators. Purged scrubber liquid must be treated by conventional waste water treatment technology to reduce suspended solids and COD. Even after such treatment, the purge stream will still contain dissolved solids. However, at many locations, the disposal of the purge stream can be accommodated without adverse environmental problems. Four commercial scrubbers, now in operation in Exxon Company, U.S.A. refineries, reduce particulate emissions to compliance levels with all pertinent regulations. SO 2 removals are in excess of 90%. Currently, four licensee companies are also applying the Exxon scrubbing process. More are anticipated. These commercial units have accumulated over 64 years of combined operations (as of February 1, 1987).
Autonomous Self-Commissioning Method for Speed-Sensorless-Controlled Induction Machines (2010)

Speed-sensorless control of ac machines at zero speed is so far only possible using signal injection methods. In particular, when applied to induction machines the spatial saturation leads to a dependence of the resulting control signals on the flux/load level. Usually, this dependence has to be identified on a special test stand during a commissioning procedure for each type of induction machine. In this paper, an autonomous commissioning method based on an artificial neural network approach is proposed that depends on neither a speed sensor present as a reference nor a load dynamometer coupled to the machine and guaranteeing constant speed. The training data for the neural network is obtained using only acceleration and deceleration measurements of the uncoupled machine. The reliability of the proposed autonomous commissioning method is proven by measurement results. When comparing the resulting sensorless control performance, the proposed commissioning method reaches the same level of performance as a manual identification method using a load dynamometer and a speed sensor.
A natural and readily available crowding agent: NMR studies of proteins in hen egg white (2010)

In vitro studies of biological macromolecules are usually performed in dilute, buffered solutions containing one or just a few different biological macromolecules. Under these conditions, the interactions among molecules are diffusion limited. On the contrary, in living systems, macromolecules of a given type are surrounded by many others, at very high total concentrations. In the last few years, there has been an increasing effort to study biological macromolecules directly in natural crowded environments, as in intact bacterial cells or by mimicking natural crowding by adding proteins, polysaccharides, or even synthetic polymers. Here, we propose the use of hen egg white (HEW) as a simple natural medium, with all features of the media of crowded cells, that could be used by any researcher without difficulty and inexpensively. We present a study of the stability and dynamics behavior of model proteins in HEW, chosen as a prototypical, readily accessible natural medium that can mimic cytosol. We show that two typical globular proteins, dissolved in HEW, give NMR spectra very similar to those obtained in dilute buffers, although dynamic parameters are clearly affected by the crowded medium. The thermal stability of one of these proteins, measured in a range comprising both heat and cold denaturation, is also similar to that in buffer. Our data open new possibilities to the study of proteins in natural crowded media.
Effects of acidified fetal bovine serum on the fibrinolytic activity and growth of cells in culture (1978)

Abstract The fibrinolytic activity of cells in culture varied with the type of serum employed in the growth medium. Degradation of iodinated fibrin occurred slowly when Rous sarcoma virus‐transformed chick embryo fibroblasts were grown in medium containing fetal bovine serum (FBS), and rapidly when chicken serum was employed. This difference reflected the low plasminogen and high inhibitor content of FBS. The inhibitors were found to be serum macromolecules that were precipitated with ammonium sulfate or polyethylene glycol, and were inactivated by boiling or upon exposure to acidic conditions. No inhibitor activity was detected in fetuin, one of the major proteins present in FBS. Acidified FBS was similar to chicken serum in that both supported high rates of cell‐mediated fibrinolytic activity. Although virally transformed hamster, mouse and chicken cells grew well in acid‐treated FBS, their normal counter‐parts did not. Apparently, acidification resulted in the formation of materials that were toxic to normal cells. These agents rapidly blocked cellular DNA synthesis.
Search for particles decaying into a Z boson and a photon in pp¯ collisions at s=1.96 TeV (2006)

We present the results of a search for a new particle X produced in pp¯ collisions at s=1.96TeV and subsequently decaying to Zγ. The search uses 0.3 fb−1 of data collected with the DØ detector at the Fermilab Tevatron Collider. We set limits on the production cross section times the branching fraction σ(pp¯→X)×B(X→Zγ) that range from 0.4 to 3.5 pb at the 95% C.L. for X with invariant masses between 100 and 1000GeV/c2, over a wide range of X decay widths.
Receptor diversity of insulin-specific T cell lines from C57BL (H-2b) mice. (1987)

To characterize the T cell receptor repertoire in an immune response in which the Ia and nominal antigenic determinants are defined and limited, we have cloned and sequenced the expressed receptors from four independent, beef insulin-specific T cell lines from C57BL mice. Each of these lines responded to beef but not to the pork insulin, thus defining the nominal antigenic determinant recognized. Furthermore, each of these lines could only be presented antigen by B6 but not mutant B6.C-H-2bm12 antigen-presenting cells, thus defining the requisite Ia recognition or antigen-association site. In spite of this functional similarity in ligand specificity, each of these T cell lines was found to use different V alpha and V beta gene segments. Moreover, structural comparisons of implied protein sequences of each of these receptors showed no stretches of conserved amino acid residues that could be implicated in ligand interaction. However, the V alpha genes used by these four clones appeared considerably more homologous to each other than were their V beta genes.

221 Burning Properties of Wasted PET-Resin Powder Using High-Temperature and Oxidizing Atmosphere Stabilized by the Annular Flame (2005)

Energy recycling of wasted plastic-resin is focused in this investigation. Fine grinding of plastic-resin and preparation of high temperature oxidizing atmosphere are indispensable for effective and successful burn-up of plastic resin. Polyethylene terephthalate resin powder is employed and the high temperature oxidizing atmosphere is generated downstream the annular burner. Temperature and O_2 concentration fields downstream the annular burner are first examined by varying the slit and circular nozzle jet velocities with both equivalence ratios kept constant and without PET-powder supply. PET-powder and stoichiometric propane-air mixture are then issued into the high temperature region by varying the slit jet velocity, the nozzle jet velocity and the median diameter of PET-powder. Variation of O_2 concentration fields and isothermals due to PET-powder combustion is also evaluated the PET flame. According to the results, the relationship between the high temperature oxidizing regions and unburnt rate of PET-powder is finally discussed.
Measurement effects on the calculation of in-flight thrust for an F404 turbofan engine (1989)

A study was performed that investigates parameter measurement effects on calculated in-flight thrust for the General Electric F404-GE-400 afterburning turbofan engine which powered the X-29A forward-swept wing research aircraft. Net-thrust uncertainty and influence coefficients were calculated and are presented. Six flight conditions were analyzed at five engine power settings each. Results were obtained using the mass flow-temperature and area-pressure thrust calculation methods, both based on the commonly used gas generator technique. Thrust uncertainty was determined using a common procedure based on the use of measurement uncertainty and influence coefficients. The effects of data nonlinearity on the uncertainty calculation procedure were studied and results are presented. The advantages and disadvantages of using this particular uncertainty procedure are discussed. A brief description of the thrust-calculation technique along with the uncertainty calculation procedure is included.
Scalable parallel extraction of linear features on MP-2 (2002)

Scalable parallel algorithms to extract linear features from a grey level image are shown. The MasPar MP-2 is modeled as a p /spl times/ p processor array. Given an n /spl times/ n image, the time complexity of the algorithm which performs linear feature extraction is O(km/sup 2/n/sup 2//p/sup 2/ + n), where the size of the convolution masks is m /spl times/ m and k denotes the number of masks used. The overall system is processor-time optimal and is scalable in the range 1 /spl les/ p/sup 2/ /spl les/ P, where P = /spl Theta/(km/sup 2/n). Based on this, a low-level vision system to extract linear features is implemented on MP-2, and the performance results are reported. Given a 512 /spl times/ 512 grey level image as input, the edge detection task consisting of applying six 5 /spl times/ 5 convolution masks takes less than 118 msec on a 4 K processor MP-2. This is a 540 fold speedup compared with the serial implementation on a SUN SPARC-400 workstation which takes 64 sec. Extraction of linear features using symbolic approaches, which includes edge detection, thinning, linking, contour tracing, and linear approximation, takes less than 1.5 sec. These implementations are scalable with respect to the machine size. Results on various sizes of images using various sizes of MP-2 are also reported. The bottlenecks and suitability of SIMD machines for low level vision processing are identified.
Approximation-based control of uncertain helicopter dynamics (2009)

In this study, the altitude and yaw angle tracking is considered for a scale model helicopter, mounted on an experimental platform, in the presence of model uncertainties, which may be caused by unmodelled dynamics, or aerodynamical disturbances from the environment. To deal with the uncertainties, approximation-based techniques using neural network (NN) are proposed. In particular, two different types of NN, namely multilayer neural network and radial basis function neural network are adopted in control design and stability analysis. Based on Lyapunov synthesis, the proposed adaptive NN control ensures that both the altitude and the yaw angle track the given bounded reference signals to a small neighbourhood of zero, and guarantees semiglobal uniform ultimate boundedness of all the closed-loop signals at the same time. The effectiveness of the proposed control is illustrated through extensive simulations. Compared with the model-based control, approximation-based control yields better tracking performance in the presence of model uncertainties.
Laser heterodyne apparatus for measurements of liquid surface properties—Theory and experiments (1976)

An apparatus has been developed, which measures the laser light scattering from thermally excited surface capillary waves of liquids. Such measurements do not cause any mechanical or thermal disturbances of the surface under study (a low-power cw He-Ne laser is used). This is especially important in the study of film-covered surfaces which are biologically interesting. Our heterodyne technique apparatus uses a grating to create a well-controlled local oscillator light beam. This is the main difference between our apparatus and those of previous workers. Compared with these apparatuses the sensitivity and resolution are considerably improved in the measured spectra, from which liquid properties such as surface tension and viscosity are calculated. A quantitative analytical theory is developed which permits optimization of the measuring set up and it is demonstrated that the predicted resolution and sensitivity are obtained in the practical measurements. It is demonstrated with higher accuracy than in earlier light scattering measurments that for a number of liquids the standard capillary wave theory correctly predicts the measured spectra. The surface tension and viscosity of water as calculated from our measurements agree within 2% and 10%, respectively, with the values known from standard mechanical measurements.
