Fabrication of Filamentary YBCO Coated Conductor by Inkjet Printing (2007)

Inkjet printing is a potentially low cost, high rate method for depositing precursors for filamentary YBCO coated conductors. The method offers considerable flexibility of filament pattern, width, and thickness. Using standard solution precursors and RABiTS substrates, the printing, processing, and properties of some inkjet-derived filamentary YBCO coated conductors for second generation (2G) wire are demonstrated on a laboratory scale. Some systematic variations of growth rate and critical transport current with filament width are observed and discussed.
Vanadium(V) Reduction by <i>Shewanella oneidensis</i> MR-1 Requires Menaquinone and Cytochromes from the Cytoplasmic and Outer Membranes (2004)

The metal-reducing bacterium Shewanella oneidensis MR-1 displays remarkable anaerobic respiratory plasticity, which is reflected in the extensive number of electron transport components encoded in its genome. In these studies, several cell components required for the reduction of vanadium(V) were determined. V(V) reduction is mediated by an electron transport chain which includes cytoplasmic membrane components (menaquinone and the tetraheme cytochrome CymA) and the outer membrane (OM) cytochrome OmcB. A partial role for the OM cytochrome OmcA was evident. Electron spin resonance spectroscopy demonstrated that V(V) was reduced to V(IV). V(V) reduction did not support anaerobic growth. This is the first report delineating specific electron transport components that are required for V(V) reduction and of a role for OM cytochromes in the reduction of a soluble metal species.

Terahertz sources and detectors using two-dimensional electronic fluid in high electron-mobility transistors (2000)

In this paper, we discuss our recent theoretical and experimental results dealing with plasma waves in high electron-mobility transistors (HEMT's) and their applications for sources and detectors operating in millimeter and submillimeter range. Plasma waves in short-channel HEMT's have a resonant response. The HEMT-based source or detector utilizing plasma waves should operate at much higher frequencies than conventional transit-time limited devices since the plasma waves propagate much faster than electrons.

Selective blockade of the endothelin subtype A receptor decreases early atherosclerosis in hamsters fed cholesterol. (1995)

Recent studies suggest that endothelin and its receptors may be involved in atherogenesis. To test this hypothesis, cholesterol-fed hamsters were treated with a selective endothelin subtype A (ETA) receptor antagonist BMS-182874. Characterization of hamster atherosclerotic plaques indicated that they contained a fibrous cap of smooth muscle cells, large macrophage-foam cells, and epitopes of oxidized low density lipoprotein. Messenger RNA for both ETA and ETB receptors was detected in aortic endothelial cells, in medial smooth muscle cells, and in macrophage-foam cells and smooth muscle cells of the fibro-fatty plaques. BMS-182874 inhibited the endothelin-1-induced pressor response whereas the depressor effect was unaltered, suggesting that vascular ETA receptors were selectively blocked in vivo. In hyperlipidemic hamsters, BMS-182874 decreased the area of the fatty streak by reducing the number and size of macrophage-foam cells. The results indicated that ETA receptors and thus endothelin promoted the early inflammatory phase of atherosclerosis.

Comparison of Laboratory and Pilot‐Plant Corn Wet‐Milling Procedures (1997)

ABSTRACT One waxy and three regular yellow dent corn hybrids were wet milled by using two scales of laboratory procedures (modified 100‐g and 1‐kg) and a pilot‐plant procedure (10‐kg). The modified 100‐g and 1‐kg laboratory procedures gave similar yields of wet‐milling fractions. Starch yields and recoveries were significantly lower for the pilot‐plant procedure, whereas gluten and fiber yields were greater because of their high contents of unrecovered starch. Protein contents of the starches obtained by all three procedures were within commercially acceptable limits (<0.50% db for normal dent corn and <0.30% for waxy corn). Rankings for starch yields and starch recoveries for the four hybrids, having very different physical and compositional properties, were the same for all three procedures. The harder the grain, the lower the yield and recovery of starch. Least significant differences ( P < 0.05) for starch yield were 0.8% for the modified 100‐g procedure, 1.2% for the 1‐kg procedure, and 2.0% for the pilot‐plant procedure.

Epoxy resin modified with soybean oil containing cyclic carbonate groups (2006)

Abstract Carbonated soybean oil (CSO) containing five‐membered cyclic carbonate groups has been obtained in the reaction of epoxidized soybean oil with carbon dioxide in the presence of KI activated by 18‐crown‐6 under 6 MPa CO 2 pressure at 130°C. The CSO was used for modification of bisphenol‐A based epoxy resin. The composition epoxide‐cyclic carbonate was cured using polyamine hardeners by one‐step and two‐step procedures. All cured compositions were characterized for their thermal and mechanical properties and compared with the parent epoxy network. The optimal properties were obtained for compositions containing CSO and cured by one‐step method when phase separation takes place. The mechanical properties were discussed in terms of morphology observed by SEM. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 2904‐2914, 2006
Ossiculoplasty prognosis: the spite method of assessment. (1992)

A series of 535 ossiculoplasties were studied to determine statistically significant links between the presence of presenting preoperative clinical features and adverse audiologic results, in order to identify those aspects of case presentation that indicate a good or poor prognosis. Analysis by chi-square testing has identified twelve features classified as surgical, prosthetic, infection, tissue, and eustachian (SPITE) factors. Regrouping the significant features has demonstrated their value in predicting accurately an ossiculoplasty prognosis. The data were used to compare accurately the results of 247 Plastipore procedures and 265 procedures using the Richards Oval-Top hydroxylapatite implant. There was no statistical difference between the series. The use of these factors will permit precise matching of future series to allow accurate comparisons of prostheses, techniques, individual skills, and also surgical philosophies such as the open and closed cholesteatoma management. Most importantly, the SPITE factors permit an accurate preoperative individual assessment when counseling the patient as to the likelihood of success or failure of a proposed ossiculoplasty.

Polyamine-Functionalized Carbon Quantum Dots as Fluorescent Probes for Selective and Sensitive Detection of Copper Ions (2012)

A novel sensing system has been designed for Cu(2+) ion detection based on the quenched fluorescence (FL) signal of branched poly(ethylenimine) (BPEI)-functionalized carbon quantum dots (CQDs). Cu(2+) ions can be captured by the amino groups of the BPEI-CQDs to form an absorbent complex at the surface of CQDs, resulting in a strong quenching of the CQDs' FL via an inner filter effect. Herein, we have demonstrated that this facile methodology can offer a rapid, reliable, and selective detection of Cu(2+) with a detection limit as low as 6 nM and a dynamic range from 10 to 1100 nM. Furthermore, the detection results for Cu(2+) ions in a river water sample obtained by this sensing system agreed well with that by inductively couple plasma mass spectrometry, suggesting the potential application of this sensing system.
Calibration and validation of the CASA phased array antenna (2012)

This paper describes the calibration and validation of one-dimension scanned phased array antenna for an X-band weather radar being developed at the Engineering Research Center for the Collaborative Adaptive Sensing of the Atmosphere (CASA). The antenna aperture is based on a linear array of vertical subarrays. Each subarray is fed by a separate Transmit/Receive (T/R) module which provides phase, amplitude and polarization diversity. The characterization and calibration of the array are based on single element measurements obtained from a portable near-field probe test system. The calibration is validated by measuring the antenna radiation pattern in a near-field antenna range. In addition, thermal stability tests are performed to estimate the system performance loss.
Unexpected heterogeneity of BCR-ABL fusion mRNA detected by polymerase chain reaction in Philadelphia chromosome-positive acute lymphoblastic leukemia. (1989)

The Philadelphia (Ph1) chromosome results in a fusion of portions of the BCR gene from chromosome 22 and the ABL gene from chromosome 9, producing a chimeric BCR-ABL mRNA and protein. In lymphoblastic leukemias, there are two molecular subtypes of the Ph1 chromosome, one with a rearrangement of the breakpoint cluster region (bcr) of the BCR gene, producing the same 8.5-kilobase BCR-ABL fusion mRNA seen in chronic myelogenous leukemia (CML), and the other, without a bcr rearrangement, producing a 7.0-kilobase BCR-ABL fusion mRNA that is seen only in acute lymphoblastic leukemia (ALL). We studied the molecular subtype of the Ph1 chromosome in 11 cases of Ph1-positive ALL, including 2 with a previous diagnosis of CML, using a sensitive method to analyze the mRNA species based on the polymerase chain reaction (PCR). We observed unexpected heterogeneity in BCR-ABL mRNA in this population; in particular, 1 of 6 bcr-rearranged cases and 1 of 5 bcr-unrearranged cases contained none of the known fusion mRNA species, while 1 of the bcr-rearranged cases contained both. This latter case is particularly interesting because it suggests that the acquisition of an additional BCR-ABL fusion species may be a mechanism of disease progression. We conclude that the PCR gives additional information about the Ph1 chromosome gene products that cannot be obtained by genomic analysis, but that it cannot be used as the sole means of detection of this chromosomal abnormality in ALL because of the high incidence of false negative results.
<italic>TextTile</italic>: An Interactive Visualization Tool for Seamless Exploratory Analysis of Structured Data and Unstructured Text (2016)

We describe TextTile, a data visualization tool for investigation of datasets and questions that require seamless and flexible analysis of structured data and unstructured text. TextTile is based on real-world data analysis problems gathered through our interaction with a number of domain experts and provides a general purpose solution to such problems. The system integrates a set of operations that can interchangeably be applied to the structured as well as to unstructured text part of the data to generate useful data summaries. Such summaries are then organized in visual tiles in a grid layout to allow their analysis and comparison. We validate TextTile with task analysis, use cases and a user study showing the system can be easily learned and proficiently used to carry out nontrivial tasks.
Building software recovery assertions from a fault injection-based propagation analysis (2002)

The author has investigated a fault injection-based technique for undermining the ability of software components to produce undesirable outputs into the state of the system. Undesirable outputs are any class of outputs that a component must not release into the state of the system given its current environment. Software components are said to be "failure-tolerant" if they release desirable outputs regardless of the programmer faults, potential malicious input data directed against the component, and other non-malicious but corrupted input data. The technology assesses the failure tolerance of software components after simulated program state corruptions are injected into the components as they execute. Based on the types of outputs that result from fault injection, the technique knows where "recovery assertions" (which act somewhat like antibodies do in an organism) should be injected into software components to ensure desirable system outputs; the second part of the approach then suggests what the assertions should be.
Coumarin-Derived Cu<sup>2+</sup>-Selective Fluorescence Sensor: Synthesis, Mechanisms, and Applications in Living Cells (2009)

A novel coumarin-based fluorogenic probe bearing the 2-picolyl unit (1) was developed as a fluorescent chemosensor with high selectivity and suitable affinity in biological systems toward Cu(2+) over other cations tested. The fluorescence on-off mechanism was studied by femtosecond time-resolved fluorescence (TRF) upconversion technique and ab initio calculations. The receptor can be applied to the monitoring of Cu(2+) ion in aqueous solution with a pH span 4-10. To confirm the suitability of 1 for biological applications, we also employed it for the fluorescence detection of the changes of intracellular Cu(2+) in cultured cells. The results indicate that 1 should be useful for the fluorescence microscopic imaging and the study on the biological functions of Cu(2+).
Effect of exposure on material response of a swelling elastomer (2009)

Purpose: This paper reports some results from a comparative study of the behavior of fresh and exposed samples of an EPDM-type water-swelling elastomer. Design/methodology/approach: Experiments were designed and performed in line with standard ASTM test methods and in consultation with petroleum development engineers. Small test fixtures were designed and fabricated, to be used together with standard testing equipment. Elastomer response was studied for hardness, compression set and tensile set (at different temperatures and for different periods of time), tensile properties (fracture strength and percent elongation), and swelling (gradual thickness and volume change with exposure to saline solution). In the swelling test, unconfined samples and samples mounted on steel plate were tested for a total duration of 1000 hours (roughly 45 days) in salt solutions of different concentrations and at different temperatures. Findings: Exposed elastomer samples (EPDM1) showed higher hardness than fresh samples (EPDM2). Compression set values of exposed samples was significantly higher than fresh ones. Tensile set values were almost the same for the two sample types after 10-min test, but were higher fort exposed elastomer after longer- duration tests. Stress-strain graphs for both sample sets were almost linear, in contrast to highly nonlinear graphs for usual rubber-type materials. Values of fracture stress and elastic modulus for exposed elastomer were noticeably higher, but percent elongation was lower. Swelling behavior showed a fluctuating trend with increasing swelling time for both elastomers. For same temperature and salinity, fresh elastomer samples yielded much more swelling than exposed samples. All of these observations indicate that such swelling elastomers lose flexibility and swelling capacity when exposed to sun and moisture, etc for extended periods of time. Practical implications: Results of this study can be used by oilfield engineers to gauge the suitability of these elastomers for downhole applications. Material properties after swelling can be used by designers using FEM or other numerical simulation methods for improvement of elastomer-based sealing and packer design. Comparison of fresh and exposed elastomer samples highlights the significant change in material response due to exposure. Originality/value: The paper presents a comparison between material properties of fresh and exposed samples of the same water-swelling elastomer. Such a comparative study, highlighting the effect of exposure on material response of an elastomer, has not been carried out before.
Trapping and tracking a local probe with a photonic force microscope (2004)

An improved type of scanning probe microscope system able to measure soft interactions between an optically trapped probe and local environment is presented. Such a system that traps and tracks thermally fluctuating probes to measure local interactions is called a photonic force microscope (PFM). The instrument can be used to study two-dimensional and three-dimensional surface forces, molecular binding forces, entropic and viscoelastic forces of single molecules, and small variations in particle flow, local diffusion, and viscosities. We introduce and characterize a PFM, and demonstrate its outstanding stability and very low noise. The probe’s position can be measured within a precision of 0.2–0.5 nm in three dimensions at a 1 MHz sampling rate. The trapping system facilitates stable trapping of latex spheres with diameter D=λ0/2 at laser powers as low as 0.6 mW in the focal plane. The ratio between the trapping stiffness and laser power was able to be optimized for various trapping conditions. The measured trap stiffnesses coincide well with the calculated stiffnesses obtained from electromagnetic theory. The design and the features of the novel PFM setup are discussed. The optical and thermodynamical principles as well as signal analysis are explained. Applications for three-dimensional, hard-clipping interaction potentials are shown. The technique discussed in this article and the results presented should be of great interest also to people working in the fields of classical optical tweezing, particle tracking, interferometry, surface inspection, nanotechnology, and scanning probe microscopy.
A novel self-starting MEMS-heat engine for thermal energy harvesting (2010)

This paper describes a novel micro heat engine for thermal energy harvesting. The engine comprises a working fluid in a sealed cavity, that is bound by a bistable membrane. The engine chamber performs a self-controlled reciprocating motion between a heat source and heat sink. Two types of working fluid are investigated: pure gas and a liquid-gas phase-change medium. A theoretical mechanical output power of is 0.89 ¿W is calculated at a temperature difference of 37°C for the phase change type engine. Measurements at 37°C temperature difference indicate an operation frequency of 0.8 Hz for the phase change engine, compared to 0.16 Hz for the pure gas engine. A maximum of 1.6 Hz is found for the air-filled engine at 100°C temperature difference.
The Preparation of 1H-Pyrazole-1-carboxylic Acid, 1, 1-Dimethylethyl Esters from Dilithiated C(α), N-Hydrazones of Hydrazinecarboxylic Acid, 1, 1-Dimethylethyl Ester (1996)

Abstract C(α), N-Hydrazones of hydrazinecarboxylic acid, 1, 1-dimethylethyl ester [C(α), N-carbo-t-butoxyhydrazones] were metalated with excess lithium diisopropylamide, and the dianion-type intermediates were condensed with select aromatic esters followed by acid cyclization to substituted 1H-pyrazole-1-carboxylic acid, 1, 1-dimethylethyl esters (N-carbo-t-butoxypyrazoles).
Identification of Conductive Hearing Loss Using Air Conduction Tests Alone (2013)

The presence of an ABG can be predicted with a reasonably high degree of accuracy using AC tests alone. Applications of such a test battery include any clinical context in which bone conduction audiometry or specialized diagnostic equipment is unavailable or impractical. Examples of these include self-fitting hearing aids, whose efficacy relies on the ability of the device to automatically administer an in situ hearing test; self-administered adult hearing screenings in both clinical and home environments; large-scale industrial hearing conservation programs; and test environments in which ambient noise levels exceed the maximum permissible levels for unoccluded ears.
Expressed Sequence Tags: An Overview (2009)

Expressed sequence tags (ESTs) are fragments of mRNA sequences derived through single sequencing reactions performed on randomly selected clones from cDNA libraries. To date, over 45 million ESTs have been generated from over 1400 different species of eukaryotes. For the most part, EST projects are used to either complement existing genome projects or serve as low-cost alternatives for purposes of gene discovery. However, with improvements in accuracy and coverage, they are beginning to find application in fields such as phylogenetics, transcript profiling and proteomics. This volume provides practical details on the generation and analysis of ESTs. Chapters are presented which cover creation of cDNA libraries; generation and processing of sequence data; bioinformatics analysis of ESTs; and their application to phylogenetics and transcript profiling.
