Evaluation of Methods to Detect Antibodies against Aspergillus fumigatus (1978)

Seventy-five sera, including sera from 23 patients with aspergillosis, 17 with tuberculosis, asthma or carcinoma, and 35 normal controls, were studied for antibody activity against Aspergillus fumigatus by agar gel double diffusion (DD), counterimmunoelectrophoresis (CIE), indirect hemagglutination (IHA) and indirect immunofluorescence (IF). Metabolic antigens produced from a selected strain of A. fumigatus were used for DD, CIE and IHA, while slide cultures of the same organism were used for IF. The results indicated that sera from the patients with aspergillosis had high IHA and IF titers, while only 91 and 87% were positive for CIE and DD methods, respectively. IHA was more sensitive than DD and CIE, and IF was equally sensitive but had false-positive reactions. CIE was simple and fast, but had false-negative and occasionally false-positive results.
Marker-Based Surgical Instrument Tracking Using Dual Kinect Sensors (2013)

This paper presents a passive-marker-based optical tracking system utilizing dual Kinect sensors and additional custom optical tracking components. To obtain sub-millimeter tracking accuracy, we introduce robust calibration of dual infrared sensors and point correspondence establishment in a stereo configuration. The 3D localization is subsequently accomplished using multiple back projection lines. The proposed system extends existing inexpensive consumer electronic devices, implements tracking algorithms, and shows the feasibility of applying the proposed low-cost system to surgical training for computer assisted surgeries.
A Phase II trial of methotrexate, vinblastine, doxorubicin, and cisplatin in the treatment of metastatic carcinoma of the uterine cervix (1997)

MVAC is an active regimen in the treatment of patients with advanced or recurrent carcinoma of the uterine cervix. It produced responses in one-half of the patients in this study, and it can be administered on an outpatient basis. The addition of G-CSF appears to reduce hematologic toxicity.

<scp>l</scp>-Arginine increases nitric oxide production in isolated lungs of chronically hypoxic newborn pigs (2000)

Previously, our laboratory found that pulmonary hypertension developed and lung nitric oxide (NO) production was reduced when piglets were exposed to chronic hypoxia (Fike CD, Kaplowitz MR, Thomas CJ, and Nelin LD. Am J Physiol Lung Cell Mol Physiol 274: L517-L526, 1998). The purposes of this study were to determine whether L-arginine addition augments NO production and to evaluate whether L-arginine uptake is impaired in isolated lungs of chronically hypoxic newborn piglets. Studies were performed by using 1- to 3-day-old piglets raised in room air (control) or 10% O(2) (chronic hypoxia) for 10-12 days. Lung NO production was assessed in isolated lungs from both groups by measuring the perfusate accumulation of nitrites and nitrates (collectively termed NO(-)(x)) before and after addition of L-arginine (10(-2) M) to the perfusate. The rate of perfusate NO(-)(x) accumulation increased by 220% (from 0.8 +/- 0.4 to 2.5 +/- 0.5 nmol/min, P < 0.05) after L-arginine addition to chronic hypoxic lungs but remained unchanged (3.2 +/- 0. 8 before vs. 3.3 +/- 0.4 nmol/min after L-arginine) in control lungs. In the second series of studies, L-arginine uptake was evaluated by measuring the perfusate concentration of L-[(3)H]arginine at fixed time intervals. The perfusate concentration of L-[(3)H]arginine at each time point was less (P < 0.05) in control than in chronic hypoxic lungs. Thus L-arginine uptake was impaired and may underlie in part the reduction in lung NO production that occurs when piglets are exposed to 10-12 days of chronic hypoxia. Moreover, these findings in isolated lungs lead to the possibility that L-arginine supplementation might increase in vivo lung NO production in piglets with chronic hypoxia-induced pulmonary hypertension.
Sputum Tobramycin Concentrations in Cystic Fibrosis Patients with Repeated Administration of Inhaled Tobramycin (2012)

No evidence of significant drug accumulation in respiratory secretions with repeat dosing of TSI was seen. Peak bioactive concentrations, although lower than peak total concentrations, were still generally well within the bactericidal range. Sputum induction as a method for determining airway drug concentrations appears safe and feasible.
DNA binding and transcription activation specificity of hepatocyte nuclear factor 4 (1998)

Hepatocyte nuclear factor 4 (HNF-4) is an orphan intracellular receptor that appears to be a key factor in the regulation of energy metabolism. In order to gain greater understanding of the binding and activation requirements of HNF-4, we performed genetic analysis of the apoCIII promoter, a promoter that has previously been shown to be highly sensitive to HNF-4-induced transcription. We identified two elements within the apoCIII promoter that bind HNF-4, either of which are sufficient to confer promoter induction in response to HNF-4. These two elements are both direct repeat-like in nature, but they differ significantly in motif sequence and the repeats are separated by either 1 or 2 nt. Therefore, to better define the DNA sequence recognition requirements of HNF-4, we utilized PCR-based binding site selection. HNF-4 selected for direct repeat-like elements with either 1 or 2 nt between the repeats. Surprisingly, the strongest selection was for a core motif that included the nucleotides between the repeats. Mutation of the nucleotide between the repeats resulted in a 6-fold reduction in affinity, indicating that the interaction between HNF-4 and the intervening nucleotide(s) is critical for high affinity binding.
Reduction of cochannel interference in cellular systems by intra-zone channel reassignment and adaptive transmitter power control (2003)

In cellular radio systems, cochannel interference determines frequency reuse distance. To achieve high-capacity systems, cochannel interference reduction is considered a key item. Intrazone channel reassignment (IZCR) and adaptive transmitter power control (ATPC), are effective techniques to reduce cochannel interference. A novel IZCR algorithm is proposed that maximizes the number of channels that satisfy a required carrier-to-interference ratio (CIR). By computer simulations, the interference reduction effects by either IZCR or ATPC and by both ATPC and IZCR are clarified. With the call block rate of 0.03 and the outage probability of 0.01, the CIR margin can be reduced by equal to or more than 10 dB by adopting both ATPC and new IZCR.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Some Direct Theories of Nonmonotonic Inheritance (1994)

Abstract Inheritance systems were originally developed within artificial intelligence in response to the practical need for an efficient way of representing and accessing taxonomic information. These systems, along with network representations more generally, were first presented without any semantic analysis at all, or else only with a procedural semantics, according to which the meaning of the representations was supposed to be specified implicitly by the programs operating on them.

Dynamic Method for Measuring the Pyroelectric Effect with Special Reference to Barium Titanate (1956)

A dynamic method has been developed for the study of the pyroelectric effect. Transient currents produced in single crystals of barium titanate when subjected to flashes of light are shown to be pyroelectric in origin. The illumination results in a small change in the temperature of the crystal which, in turn, causes the polarization to change. This change is recorded as a current in the external circuit. It is shown that from room temperature up to the Curie point, the pyroelectric current is consistent with the polarization as a function of temperature, as determined from hysteresis loop measurements. The technique proves to be a sensitive and nondestructive method for studying the state of polarization of a crystal. The technique is used to study the pyroelectric effect induced by applied static electric fields at temperatures above the Curie point. The results are consistent with Devonshire's theory of the ferroelectricity of BaTiO3, and they confirm that the Curie point transition is of the first order.
Phonatory characteristics of excised pig, sheep, and cow larynges (2008)

The purpose of this study was to examine the phonatory characteristics of pig, sheep, and cow excised larynges and to find out which of these animal species is the best model for human phonation. Excised pig, sheep, and cow larynges were prepared and mounted over a tapered tube on the excised bench that supplied pressurized, heated, and humidified air in a manner similar to that for excised canine models. Each excised larynx was subjected to a series of pressure-flow experiments with adduction as major control parameter. The subglottal pressure, electroglottograph (EGG), mean flow rate, audio signal, and sound pressure level were recorded during each experiment. EGG signal was used to extract the fundamental frequency. It was found that pressure-frequency relations were nonlinear for these species with large rate of frequency changes for the pig. The average oscillation frequencies for these species were 220+/-57 Hz for the pig, 102+/-33 Hz for the sheep, and 73+/-10 Hz for the cow. The average phonation threshold pressure for the pig was 7.4+/-2.0 cm H(2)O, 6.9+/-2.9 cm H(2)O for the sheep, and 4.4+/-2.3 cm H(2)O for the cow.

Stat,e-of-the-art low loss, high isolation SP6T switch for handset applications (2004)

In this paper, the design and measurement of a low cost high performance SPLT gallium-arsenide switch are discussed. The design uses a novel approach to reduce receive path loss and to achieve >40dB TX-RX isolation. It is implemented with the Filtronic Compound Semiconductors 0.5um D-mode GaAs pHEMT process. The switch can be configured to connect different GSM / GPRS / EDGE 850 / 900 / 1800 / 1900 MHz transceivers to a common antenna and can be used in all systems requiring high power at control voltages down to 2.5V. The MMIC measures only 1.1 mm2. Transmit loss is less than 0.6 dB at 2 GHz, receive loss is less than 1 dB.
A corpus analysis approach for automatic query expansion and its extension to multiple databases (1999)

Searching online text collections can be both rewarding and frustrating. While valuable information can be found, typically many irrelevant documents are also retrieved, while many relevant ones are missed. Terminology mismatches between the user's query and document contents are a main cause of retrieval failures. Expanding a user's query with related words can improve search performances, but finding and using related words is an open problem. This research uses corpus analysis techniques to automatically discover similar words directly from the contents of the databases which are not tagged with part-of-speech labels. Using these similarities, user queries are automatically expanded, resulting in conceptual retrieval rather than requiring exact word matches between queries and documents. We are able to achieve a 7.6% improvement for TREC 5 queries and up to a 28.5% improvement on the narrow-domain Cystic Fibrosis collection. This work has been extended to multidatabase collections where each subdatabase has a collection-specific similarity matrix associated with it. If the best matrix is selected, substantial search improvements are possible. Various techniques to select the appropriate matrix for a particular query are analyzed, and a 4.8% improvement in the results is validated.
Kinetic Study of the Combustion of Phosphorus Containing Species (1999)

The combustion of organophosphorus compounds is of great interest for the incineration of chemical warfare agent and their use in flame inhibition as halon replacement. The thermochemical data of these species and the reactions involved at high temperature are not well known, despite some recent experimental studies. With BAC-MP4 ab initio estimations as a basis and semi-empirical estimations for many new compounds, the thermochemistry of organophosphorus compounds is studied. New group additivity values are proposed for enthalpies of formation at 298K, entropies and heat capacities of species involving pentavalent phosphorus bonded to carbon, hydrogen, oxygen, fluorine, nitrogen and sulfur atoms. The kinetic of unimolecular elimination is investigated by modeling pyrolysis experiments of DEMP, TEP and DIMP. A new combustion mechanism is described and applied to the modeling of DMMP reaction in a H{sub 2}/O{sub 2} flame.
Real-Time Determination of a BDS Satellite's Velocity Using the Broadcast Ephemeris (2014)

This paper studies the algorithms for determining a BDS satellite's velocity using the broadcast ephemeri. Firstly, by taking the time derivatives of the Kepler orbit elements and the correction terms, the algorithm comprises close-form analysis formulas and the processing steps for directly computing a BDS satellite's instant velocity using the broadcast ephemeris is derived, and its validity is verified by test. Further, it is discussed on how the size of the differential time step affects the accuracy of the velocity results computed using the position differential algorithm. To investigate the suitable magnitudes of the differential time step, a comprehensive test is performed. In this test, several BDS satellites with different types were specially chosen and the real broadcast ephemeris was used to determine the velocity vectors both by the position differential algorithm and the direct algorithm, and the results were compared. The 12hr comparison test illustrates that the differential time step magnitude suitable for computing a BDS GEO satellite's velocity is 1s and the max residual is less than 0.0001mm/s. The differential time step suitable for a BDS MEO/IGSO Satellite is 100ms and the max residual is less than 0.001mm/s.
Minimum Price Variations, Discrete Bid–Ask Spreads, and Quotation Sizes (1994)

Exchange minimum price variation regulations create discrete bid–ask spreads. If the minimum quotable spread exceeds the spread that otherwise would be quoted, spreads will be wide and the number of shares offered at the bid and ask may be large. A cross-sectional discrete spread model is estimated by using intraday stock quotation spread frequencies. The results are used to project |${\boldsymbol \$} {\textstyle{1 \over {16}}}$| spread usage frequencies given a |${\boldsymbol \$} {\textstyle{1 \over {16}}}$| tick. Projected changes in quotation sizes and in trade volumes are obtained from regression models. For stocks priced under $10, the models predict spreads would decrease 38 percent, quotation sizes would decrease 16 percent, and daily volume would increase 34 percent.
Morphotropic domain structures and phase transitions in relaxor-based piezo-/ferroelectric (1−x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 single crystals (2000)

The domain structures and phase transitions of relaxor-based piezo-/ferroelectric (1−x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 [PMNT] single crystals, grown from high temperature solutions, have been analyzed by polarized light microscopy using an optical crystallographic approach. The substitution of Ti4+ ions for the B-site complex (Mg1/3Nb2/3)4+ ions in the relaxor PMN results in a long-range symmetry breaking, as revealed by the formation of birefringent macrodomains. The domain structures of the PMNT80/20 crystals indicate a primitive trigonal symmetry at room temperature with a weak birefringence. PMNT crystals with 50% Ti show tetragonal domain structures, reflecting the symmetry of PbTiO3. Single crystals of PMNT65/35 exhibit complex morphotropic domain structures, which are composed of both the trigonal and the tetragonal phase intimately mixed together. The domain structures, the sequence and temperature of phase transitions have been interpreted in relation to the morphotropic phase boundary behavior of the PMN-PT system. It is shown that in situ analysis of domain structures and phase transitions can be used as a nondestructive analytical tool for evaluating the local morphotropic composition and the properties, which sensitively depend upon the individual domains and the Ti4+ concentration. The analysis of morphotropic domain structures and phase transitions provides a better understanding of the microscopic mechanisms of the enhanced piezoelectric properties recently disclosed in PMNT and other relaxor-based piezocrystals.
The cognition of basic musical structures (2002)

In this book, David Temperley addresses a fundamental question about music cognition: how do we extract basic kinds of musical information, such as meter, phrase structure, counterpoint, pitch spelling, harmony, and key from music as we hear it? Taking a computational approach, Temperley develops models for generating these aspects of musical structure. The models he proposes are based on preference rules, which are criteria for evaluating a possible structural analysis of a piece of music. A preference rule system evaluates many possible interpretations and chooses the one that best satisfies the rules.After an introductory chapter, Temperley presents preference rule systems for generating six basic kinds of musical structure: meter, phrase structure, contrapuntal structure, harmony, and key, as well as pitch spelling (the labeling of pitch events with spellings such as A flat or G sharp). He suggests that preference rule systems not only show how musical structures are inferred, but also shed light on other aspects of music. He substantiates this claim with discussions of musical ambiguity, retrospective revision, expectation, and music outside the Western canon (rock and traditional African music). He proposes a framework for the description of musical styles based on preference rule systems and explores the relevance of preference rule systems to higher-level aspects of music, such as musical schemata, narrative and drama, and musical tension.
Cathodic Disintegration of Tin (1958)

Disintegration of tin cathodes at high current densities was studied in neutral, acid, and alkaline solutions of sulfuric acid and alkali and ammonium hydroxides, sulfates, and chlorides. The tin left the surface as and the were of the order of amp/cm2. Acid decreased the disintegration rate, salts added to acid increased the rate, salts added to neutral solution decreased the rate. The cation effect was specific, disintegration rates decreasing in the order sodium, potassium, lithium, ammonium, and hydronium ion.

Noncoherent BOC Signal Tracking Based on a Five-Correlator Architecture (2012)

The work presented here addresses the design and analysis of a noncoherent five-correlator code tracking scheme, which is considered minimal in BOC (binary offset carrier) signal tracking. The design flexibilities associated with a general noncoherent tracking loop including correlator spacing and weighting coefficients are identified and determined through an optimization process to meet design requirements including ambiguity-free, multipath mitigation, and tracking error minimization. The discriminator design is assessed through design examples.

Constructions and Noise Threshold of Hyperbolic Surface Codes (2016)

We show how to obtain concrete constructions of homological quantum codes based on tilings of 2-D surfaces with constant negative curvature (hyperbolic surfaces). This construction results in 2-D quantum codes whose tradeoff of encoding rate versus protection is more favorable than for the surface code. These surface codes would require variable length connections between qubits, as determined by the hyperbolic geometry. We provide numerical estimates of the value of the noise threshold and logical error probability of these codes against independent X or Z noise, assuming noise-free error correction.
