Cooper Pair Writing at the LaAlO3/SrTiO3 Interface (2010)

The LaAlO3/SrTiO3 interface provides a unique platform for controlling the electronic properties of the superconducting semiconductor SrTiO3. Prior investigations have shown that two-dimensional superconductivity can be produced at the LaAlO3/SrTiO3 interface and tuned electrostatically. The recently demonstrated reversible control of the metal-insulator transition at the same interface using conductive atomic force microscopy (c-AFM) raises the question of whether this room-temperature technique can produce structures that exhibit superconducting, normal metallic and insulating phases at sub-Kelvin temperatures. Here we report low-temperature magnetotransport experiments on conducting structures defined at an otherwise insulating LaAlO3/SrTiO3 interface. A quantum phase transition associated with the formation of Cooper pairs is observed in these predefined structures at sub-Kelvin temperatures. However, a finite resistance remains even at the lowest temperature. At higher magnetic fields, interfaces with high mobility also exhibit strong Shubnikov-de Haas oscillations as well as a larger Ginsburg-Landau coherence length. Cooper pair localization, spin-orbit coupling, and finite-size effects may factor into an explanation for some of the unusual properties observed.
Extension of the “Equivalent Cable Bundle Method” for Modeling Electromagnetic Emissions of Complex Cable Bundles (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper presents an extension of the so-called “Equivalent Cable Bundle Method” for the computation over a large frequency range of the electromagnetic radiation of complex cable bundles. The purpose of the method is to reduce the complexity of the problem by grouping together the conductors according to their terminal load configuration and their excitation to reduce the required computation time for the complete cable bundle modeling. As far as the use of the method on emission problems is concerned, a new five-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundles. After the description of the adjustments required for the application of the method to emitting cases, some numerical and experimental validations performed on simple cable bundles illustrate the efficiency and the advantages of the method. The research described in this paper is considered as a new step in the study of the modeling of complex cable bundles at “high frequencies.” </para>

Mechanical testing of advanced coating system, volume 1 (1990)

The Electron Beam Physical Vapor Deposition (EBPVD) coating material has a highly columnar microstructure, and as a result it was expected to have very low tensile strength. To be able to fabricate the required compression and tensile specimens, a substrate was required to provide structural integrity for the specimens. Substrate and coating dimensions were adjusted to provide sufficient sensitivity to resolve the projected loads carried by the EBPVD coating. The use of two distinctively different strain transducer systems, for tension and compression loadings, mandated two vastly different specimen geometries. Compression specimen and tensile specimen geometries are given. Both compression and tensile test setups are described. Data reduction mathematical models are given and discussed in detail as is the interpretation of the results. Creep test data is also given and discussed.

Oxygen consumption of single muscle fibres of Rana temporaria and Xenopus laevis at 20 degrees C. (1988)

1. Oxygen consumption of contracting single muscle fibres of Rana temporaria and Xenopus laevis was investigated at 20 degrees C. 2. Single fibres of the tibialis anterior muscle of Rana and the iliofibularis muscle of Xenopus were mounted in a chamber containing Ringer solution. The solution was stirred and its partial pressure of oxygen (PO2) was continuously measured polarographically. 3. Steady-state rates of oxygen consumption (VO2) of single fibres were determined as a function of twitch frequency (0.2-12 stimuli s-1, depending on the type of fibre). VO2 increased with twitch frequency until a plateau value (VO2,max) was reached. VO2,max of different fibres ranged from 0.042 to 0.169 nmol O2 s-1 mg-1 dry weight in Rana and from 0.045 to 0.412 nmol O2 s-1 mg-1 dry weight in Xenopus. Under VO2,max conditions oxygen availability was not the limiting factor. 4. VO2 after injection of the uncoupler carbonyl cyanide m-chlorophenylhydrazone (CCCP) into the chamber correlated with VO2,max, suggesting that VO2,max is determined by mitochondrial density. This suggestion was confirmed by the observation that a close relationship exists between VO2,max and succinate dehydrogenase activity in three different fibre types of Xenopus. 5. At VO2,max a considerable amount of oxygen was taken up after the twitch train by most fibres, indicating that the oxidative ATP synthesis cannot match ATP hydrolysis. Xenopus muscle fibres with high oxidative capacity did not show this phenomenon. 6. The results are discussed in relation to the occurrence of anoxic cores in muscle fibres and the maximum steady-state contractile activity attainable by the fibres.
Implementing the NASA Deep Space LDPC Codes for Defense Applications (2013)

Selected codes from, and extended from, the NASA's deep space low-density parity-check (LDPC) codes are implemented for high speed defense applications. This is part of an effort to build Government reference waveform implementations to assist defense acquisition programs and to promote waveform re-use. Details of the decoder implementation, including memory layout, parallelization architecture, layered-decoding scheduling, and field programmable gate array (FPGA) resource utilization are presented.
Pulse Propagation on Multi-Layered Circuit-Level Interconnects (1990)

High-speed pulse propagation on terminated dual-level interconnects is investigated. The interconnects, modeled as multiconductor microstrip embedded in a layered dielectric substrate, are analyzed by using a full-wave approach to calculate dispersive eigencurrents, modal impedances, and mode speeds. The effects of dispersion on digital signal propagation are assessed upon comparison with results calculated using a frequency-independent TEM analysis. Termination effects are studied by investigating an example of five parallel running dual layered circuit level interconnects, with two lines on one plane and three on the other.

Capillary electrophoresis for purity estimation and in-process testing of recombinant GB virus-C proteins. (1997)

Protein purity estimation by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) coupled with scanning densitometry is a critical component in the manufacture of recombinant proteins for commercial diagnostic assays. However, the procedure is time consuming and often difficult to reproduce because commercial dyes that are used for visualizing proteins do not bind in a stoichiometric fashion for all proteins. The present report describes the use of a rapid and dye-independent SDS polymer-filled capillary gel electrophoresis (CE-SDS) method to estimate protein purity. The CE-SDS method was used for in-process and final purity testing of GB virus-C (GBV-C) fusion proteins produced in E. coli, and was directly compared with the conventional SDS-PAGE method using purified Coomassie blue dye to reduce protein staining anomalies. The CE-SDS method may serve as an alternative or replacement method to the lengthy and tedious SDS-PAGE method. This study also demonstrates that the observed molecular weight of the fusion protein, determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), provides higher accuracy than values estimated by either CE-SDS or SDS-PAGE methods.
In-Line Measurement of H2S Content in Flow with a Multiphase Flow Meter - Case Study in a Giant Field under Sour Gas Re-Injection (2015)

Abstract A new approach in advanced multiphase metering methodology designed for use in sour fields, quantifying H2S content in flow and properly accounting for it in the different phase rate measurements is presented. Flow metering in sour fields is challenging due to the need for containment of produced fluids and the effect of fluid properties in the interpretation of the measurements. The addition of H2S measurement provides additional information for production and reservoir monitoring and also yields improvements in flow metering, accounting for variations in fluid properties used for multi-phase calculation. Multiphase Flow Meters (MPFM) utilizing multi-energy gamma-ray fraction measurements are based on the ability of oil, gas, and water to absorb gamma rays of two different wavelengths. Adding an extra measurement at a third level of energy and leveraging the large contrast between the attenuation of sulfur and that of hydrocarbon and water components makes it possible to determine the mass fraction of H2S as an additional output. This technique was applied in Tengiz field, Kazakhstan, characterized by a high H2S content. In order to maintain reservoir pressure, improve recovery and utilize produced associated gas, a sour gas miscible flood pilot was started in 2007. The monitoring of compositional variation in producers is critical in the understanding of solvent (sour gas) distribution and thus in managing production-injection patterns to optimize plant throughput. Early field trials of the method were made comparing metered H2S content with surface PVT samples, confirming the accuracy of the methodology. The technology was then implemented systematically but strategically across the field. The in-line H2S measurement with automatic updates for variation in fluid properties was applied in two distinct areas: within the sour gas injection pilot area, where solvent levels vary, and outside the area where hydrocarbon composition is known to be homogeneous and constant. Long and short term tests with multi-rate well tests were conducted. Full datasets were collected from the MPFM to evaluate measurement stability and representativity under different flowing conditions and compared to results obtained without accounting for compositional changes. The results show a stable, accurate and continuous measurement of H2S content in produced fluid and an enhanced measurements of water, oil and gas rates comparable with PVT results. The in-line H2S measurement based on multi-energy gamma ray measurements is the only continuous H2S measurement technology available in multiphase flow conditions. It can be retrofitted to existing MPFMs, allowing to get additional parameter and enhanced stability of flow rate measurements where properties of produced fluid vary continuously. This paper will begin with a presentation of the theory, formulation and validation of the in-line H2S measurement and then go on to present a case history of the application in the Tengiz field, Kazakhstan for Tengizchevroil (TCO).

Key Neuroprotective Role for Endogenous Adenosine A <sub>1</sub> Receptor Activation During Asphyxia in the Fetal Sheep (2003)

These data support the hypothesis that endogenous activation of the adenosine A1 receptor during severe asphyxia mediates the initial suppression of neural activity and is an important mechanism that protects the fetal brain.
Methods for cryopreservation of human ovarian tissue Outi Hovatta is Professor in Obstetrics and Gynaecology in the Karolinska Institute in (2005)

Human ovarian tissue can be successfully cryopreserved, with good survival and function after thawing. Experimental animal studies regarding ovarian tissue cryopreservation resulting in live-born offspring preceded the present freezing systems in humans. On the basis of current knowledge, the standard method for human ovarian cryopreservation is slow programmed freezing, using human serum albumin-containing medium, and propanediol, dimethylsulphoxide (DMSO) or ethylene glycol as a cryoprotectant, combined with sucrose. Vitrification is still at the experimental stage. Whole organ cryopreservation is an interesting experimental option. Transplantation of the frozen–thawed tissue is a feasible method to utilize the tissue in infertility treatment. Ovarian function has been restored in humans. Because one healthy child has already been born from cryopreserved tissue, tissue cryopreservation should perhaps be offered to all young girls and women who can be predicted to undergo premature ovarian failure due to cancer treatment or genetic causes. Maturation of follicles in vitro from frozen–thawed tissue is another option that is still under development.
An Algebraic Multigrid Solver for Analytical with Layout Based Clustering Placement (2003)

2 ABSTRACT efficient matrix solver is critical to the analytical placement. As the size of the matrix becomes huge, the multilevel methods tum out to be more efficient and more scalable. Algebraic Multigrid (AMG) is a multilevel technique to speedup the iterative matrix solver (lo). We apply the algebraic multigrid method to solve the linear equations that arise from the analytical placement. A layout based clustering scheme is put forward to generate coarsening levels for the multigrid method. The experimental results show that the algebraic multigrid solver is promising for analytical placement.

Molecular characterization of primary mediastinal B cell lymphoma. (1996)

Primary mediastinal B cell lymphoma (PMBL) is a diffuse large B cell lymphoma (DLCL) postulated to arise from noncirculating thymic B lymphocytes. Because of its distinctive clinical and morphological features and putative unique cellular origin, PMBL is generally considered a distinct clinicopathological entity. Little is known, however, about the molecular characteristics of PMBL. Therefore, we analyzed 16 PMBLs for molecular alterations involving the bcl-1, bcl-2, bcl-6, c-myc, H-ras, K-ras, N-ras, and p53 genes and for Epstein-Barr virus infection, which are commonly involved in lymphoid neoplasia. Employing a combination of Southern blotting and/or polymerase chain reaction and single-strand conformation polymorphism assays, we detected genetic alterations in 7 of the 16 (44%) PMBLs. Whereas the bcl-6 gene is rearranged in up to 45% of DLCLs, rearrangement of the bcl-6 gene was detected in only 1 of these 16 (6%) PMBLS. Point mutations of the 5' noncoding region of the c-myc gene were demonstrated in 3 other cases (19%), although c-myc gene rearrangements were not seen by Southern blotting. Missense point mutations of the p53 gene were identified in 3 additional PMBLs (19%). Alterations of the bcl-1, bcl-2, or ras genes and evidence of Epstein-Barr virus infection were not observed. In conclusion, a variety of molecular lesions occur in PMBLs and may be involved in their pathogenesis. This molecular genetic pattern bears little resemblance to that known for other B cell malignancies, including DLCL. In particular, the infrequent occurrence of bcl-6 gene rearrangement in PMBLs distinguishes them from other DLCLs of B cell origin, suggesting that PMBLs do not represent a distinct subtype of DLCL.
Analysis of a PMD insensitive polarization multiplexed coherent optical OFDM system for 100 Gb/s optical transmission (2012)

A novel polarization multiplexed coherent optical OFDM system is proposed and experimentally demonstrated for 100 Gb/s transmission. In this technique, two signals can be transmitted at the same wavelength with orthogonal state of polarization through OFDM transmitter and at the receiver end those signals are received by coherent detector. The implemented model can be treated as a special kind of multiple-input multiple output (MIMO) model which is intrinsically represented by a two-element Jones vector. Though PMD represents a major source of performance degradation in polarization multiplexed systems due to its polarization sensitive detection, the special MIMO system successfully mitigates the effect without any extra compensation system. Performance of the system is evaluated through simulation and different criteria are analyzed with the simulation result.
Event driven semantics based ad selection (2005)

The growth of digital television over satellite, cable, and terrestrial networks has driven advertisers to "better target" users by customized and personalized advertisements. Advertisements, whose content and theme are relevant and related to ongoing programs, content and theme, are known to have better impact on viewers. We propose a system for the selection, filtering, and presentation of advertisements based on detected program events and profiles contained in the home information system. A comprehensive event prediction and event analysis is performed based on which relevant ads are either selected for transport stream insertion or for caching purposes. The system also describes the notion of ActiveAd to achieve self-evaluation and self-transformation of an ad to increase its relevance with respect to an event.
Case Report: Fatal Pulmonary Embolization After Reaming of the Femoral Medullary Cavity in Sclerosing Osteomyelitis: A Case Report (1996)

Reaming of the medullary may be used in cases of sclerosing osteomyelitis (type Garré), refractory to other methods. We report a case of fatal intraoperative complication related to this procedure. An otherwise healthy young patient died during reaming using a machine-driven reamer of the femoral medullary canal due to pulmonary bone embolism. The technique and the indication for this procedure as well as the intraoperative monitoring options are discussed.
Store-Operated Ca<sup>2+</sup>Entry in Sensory Neurons: Functional Role and the Effect of Painful Nerve Injury (2011)

Painful nerve injury disrupts levels of cytoplasmic and stored Ca(2+) in sensory neurons. Since influx of Ca(2+) may occur through store-operated Ca(2+) entry (SOCE) as well as voltage- and ligand-activated pathways, we sought confirmation of SOCE in sensory neurons from adult rats and examined whether dysfunction of SOCE is a possible pathogenic mechanism. Dorsal root ganglion neurons displayed a fall in resting cytoplasmic Ca(2+) concentration when bath Ca(2+) was withdrawn, and a subsequent elevation of cytoplasmic Ca(2+) concentration (40 ± 5 nm) when Ca(2+) was reintroduced, which was amplified by store depletion with thapsigargin (1 μm), and was significantly reduced by blockers of SOCE, but was unaffected by antagonists of voltage-gated membrane Ca(2+) channels. We identified the underlying inwardly rectifying Ca(2+)-dependent I(CRAC) (Ca(2+) release activated current), as well as a large thapsigargin-sensitive inward current activated by withdrawal of bath divalent cations, representing SOCE. Molecular components of SOCE, specifically STIM1 and Orai1, were confirmed in sensory neurons at both the transcript and protein levels. Axonal injury by spinal nerve ligation (SNL) elevated SOCE and I(CRAC). However, SOCE was comparable in injured and control neurons when stores were maximally depleted by thapsigargin, and STIM1 and Orai1 levels were not altered by SNL, showing that upregulation of SOCE after SNL is driven by store depletion. Blockade of SOCE increased neuronal excitability in control and injured neurons, whereas injured neurons showed particular dependence on SOCE for maintaining levels of cytoplasmic and stored Ca(2+), which indicates a compensatory role for SOCE after injury.
