Excess Pore Water Pressure along the Friction Sleeve of a Piezocone Penetrating in Clay: Numerical Study (2020)

Excess pore water pressure (EPWP) measurements taken at different positions on a penetrating piezocone into a clayey soil are believed to play an important role in correlating to its characteristics. On this subject, many correlations were proposed by several researchers, mainly empirically and mostly with EPWPs measured at the cone shoulder (u2). The use of EPWP measurements at other positions, for example, behind the friction sleeve (u3) has not been evaluated, possibly because of the lack of u3 measuring elements for most penetrometers on the market. In this study, the piezocone penetration test in saturated intact clays was numerically modeled using finite element formulation. The EPWP distribution generated along the friction sleeve was investigated and it was found that the previously mentioned distribution closely followed an exponential trend which was mainly affected by the overconsolidation ratio (OCR) and the rigidity index (Ir) of the soil. Further investigations led this study to propose an innovative relationship to estimate u3 values from measurements of common piezocone tests on the market (u2-type) and pertinent soil characteristics. The well-predicting capability of numerical modeling procedures and the proposed relationship was compared with and validated with available experimental and field piezocone test measurements.
Dimilin for Control of Lernaea in Golden Shiner Ponds (1987)

A single application of Oimilin (UNIROYAL),diflubenzuron, was tested in 9 (nine) ponds containing golden shiner minnows, Notemigonus crysoleucas, infested with the parasitic copepod Lernaea cyprinacea. The chemical was applied at a rate of1 0 or 30 pg/l and compared to untreated controls. Fish were periodically sampled to determine levels of infestation, and zooplankton numbers were monitored for chemical effect. Oimilin treatment significantly reduced (P < 0.05) parasite infestation four to eight days after treatment. No significant difference (P < 0.05) was noted between the two levels of treatment. Zooplankton populations decreased in the Dimilin treated ponds following chemical application. Rotifer populations rebounded later during the period, but copepod populations in the ponds treated with 30 ng/L remained depressed from two days after treatment for one month until the study ended. Complete parasite control was not obtained with either chemical concentration using a single application. These results suggest that a single treatment is not effective for Lernaea control. Future research will test two applications 10 days apart at the 10 and 30 /xg/L levels.

Prenatal diagnosis of ornithine carbamoyl transferase deficiency using a gene specific probe. (1985)

A gene specific DNA probe has been used to predict the genotype of two fetuses in families at risk for ornithine carbamoyl transferase deficiency. Although the probe does not detect the mutation directly, prediction was possible by examining restriction fragment length polymorphisms of the parents and sibs to identify the X chromosome carrying the mutation. It is suggested that in all pregnancies, regardless of the predicted outcome, the biochemical status of carrier mothers should be monitored because hyperammonaemia and arginine deficiency may have a deleterious effect on the fetus.
Adaptive stream fusion in multistream recognition of speech (2011)

A new method to deal with variable distortions of speech during the operation of the system is proposed. First, multiple processing streams are formed by extracting different spectral and temporal modulation components from the speech signal. Information in each stream is used to estimate posterior probabilities of phonemes. Initial values for a weighted integration of these individual estimates are found by normalized cross-correlation of the estimates with the actual phoneme labels on the training data. A statistical model of the final estimated posterior probabilities is used to characterize the system performance. During the operation, the weights in the linear fusion are adapted using particle filtering to optimize the performance. Results on phoneme recognition from noisy speech indicate the effectiveness of the proposed method.
Fusion of genes encoding Escherichia coli heat-stable enterotoxin and outer membrane protein OmpC (1989)

The OmpC outer membrane protein of Escherichia coli was used as a carrier molecule for the nonimmunogenic heat-stable enterotoxin STa. Two fragments of different lengths of the gene encoding STa were fused in vitro to the 3' terminus of the truncated ompC gene. The resulting OmpC-STa hybrid proteins could be detected by L-[35S]cysteine labeling, and they were processed and thus exported. All synthesized hybrid protein remained cell bound and was found by fractionation mainly in the periplasm. Immunoblot analysis showed that the hybrid proteins reacted in vitro both with anti-OmpC and anti-STa antibodies, and immunization of rabbits evoked an antibody response to either of these proteins.
A framework for management and control of distributed applications using agents and IP-multicast (1999)

As more and more applications on the Internet become network aware the need and possibility to remotely control them becomes larger. This paper presents a framework for control and management of distributed applications and components. This is done using IP-multicast and an agent based application architecture. The target of the framework is to allow for resource discovery of both controllable elements and available control points in the these elements as well as real-time control. All this is done in scalable and secure way based on IP-multicast and asymmetric cryptography. The presented framework is also independent of the underlying transport mechanism to allow for flexibility and easy deployment. The framework bandwidth usage and introduced control delay is presented. Details on the reference implementation of the framework and example usage scenarios where the framework is used to create bandwidth adaptive applications and better group awareness is also presented.
[11C]Methionine Positron Emission Tomography for the Evaluation of Pancreatic Exocrine Function in Chronic Pancreatitis (2001)

Positron emission tomography (PET) can be used for the quantitative analysis of amino acid metabolism. The aim of this study was to investigate whether pancreatic exocrine function can be evaluated by [11C]methionine PET in chronic pancreatitis (CP) patients. Dynamic PET scan of the pancreas and liver was performed in eight healthy subjects and seven patients with CP after intravenous (i.v.) injection of [11C]methionine. Simultaneously, duodenal juice was collected with the background of continuous i.v. administration of secretin (125 ng/kg/h). The radioactivity ratio of the pancreas to that of the liver (PLR) was calculated by regions of interest (ROI) analysis. Amylase output and bicarbonate concentration were measured in the duodenal aspirates. The PLR of CP patients was significantly lower than that of healthy subjects at all time points after methionine injection. The PLRs at 4.5 minutes (PLR4.5) after methionine injection were positively correlated with the amylase output, mean bicarbonate concentration, and volume of duodenal aspirates (R = 0.74, 0.69, 0.46). It is concluded that [11C]methionine PET would be a noninvasive method for the evaluation of exocrine pancreatic function, which may represent total amino acids uptake of viable acinar cells in the pancreas.
Method of Studying Multi-Region Reactors with an Analog Computer (1957)

An electrical analog is described for the study of reactors whose nuclear properties vary with radius. Several neutron velocity groups can be used. The reactor is divided in uniform homogeneous regions which may be either slabs, spherical shells, or cylindrical shells. The group parameters may be independently varied in these regions and the analog immediately obtains the reactivity. The analog also yields the space distribution of the various neutron groups after being adjusted to the critical condition. A commercial, general purpose analog computer has been adapted to this problem. The analog can also solve the adjoint diffusion equations.

Evaluation of a 3 kWel Reformer-operated High Temperature PEM System – Experiment and Simulation (2012)

High temperature polymer electrolyte membrane fuel cells (HT-PEMFC) can be operated with reformate containing carbon monoxide levels up to several vol.-%. This enables the design of a coupled reformer fuel cell system with reduced complexity and enhanced robustness. \n\nAn experimental study and an Aspen Plus system model is presented. The experimental results were obtained with a methane reforming unit (WS Reformer) and a fuel cell module with three stacks and 76 cells each (SerEnergy). The characterization of the components was focused on the effect of different process parameters on system behaviour and total system efficiency. Mainly the variation of CO concentration, operation temperature, load and water content of the anode feed gas were investigated. \n\nBoth subsystems were modelled using Aspen Plus flowsheeting software. The reforming and the water gas shift reactors were realized by a Gibbs reactor model. Kinetic limitations have been taken into consideration by applying a temperature approach in Aspen Plus, which allows for non-equilibrium conditions in the product gas. The reformate gas composition from the model shows good agreement with the experimental results. The hydrogen conversion efficiency reaches 72 to 75 %. Based on the experimental results the fuel cell module was modelled taking into account the dependence of performance on the operation parameters of the module. This was realized by the implementation of a performance map. \n\nThe Aspen model of the coupled process including hydrogen generation and fuel cell system was then used for process optimization. Thermal integration was realized by applying the Pinch Method. As a result, an optimized system configuration could be identified.\n\nFor the coupled reformer-HTPEM-system an overall electric efficiency of 30 - 40 % can be achieved.\n
RFID tag antenna based wireless sensing method for medical transfusion applications (2012)

Real-time fluid-level monitoring in a medical transfusion procedure is very important for the safety and satisfaction of patients in hospitals. Traditional approaches rely on either the regular check by hospital staffs or the self-monitoring by patients. In this paper, a RFID based approach to automatically monitor the fluid level is introduced, where a passive and low cost tag is attached to a transfusion bag/bottle, and a center reader records the minimum transmitted power to activate the tag. The fluid level in a transfusion bag/bottle is then derived from the transmitted power level. Various experiments have been conducted to demonstrate the proposed method, including the tag orientations, bag/bottle rotation angles, and continuous fluid level changes. The measured data validate the feasibility of the wireless sensing approach.
A framework for scalable dissemination-based systems (1997)

The dramatic improvements in global interconnectivity due to intranets, extranets, and the Internet has led to an explosion in the number and variety of new data-intensive applications. Along with the proliferation of these new applications have come increased problems of scale. This is demonstrated by frequent delays and service, disruptions when accessing networked data sources. Recently, push-based techniques have been proposed as a solution to scalability problems for distributed applications. This paper argues that push indeed has its place, but that it is just one aspect of a much larger design space for distributed information systems. We propose the notion of a Dissemination-Based Information System (DBIS) which integrates a variety of data delivery mechanisms and information broker hierarchies. We discuss the properties of such systems and provide some insight into the architectural imperatives that will influence their design. The DBIS framework can serve as the basis for development of a toolkit for constructing distributed information systems that better match the technology they employ to the characteristics of the applications they are intended to support.
Improved Response of Bubble Detectors to High Energy Neutrons (2000)

Bubble detectors are currently used both for personal neutron dosimetry, en~ronmental neutron dosimetry and for assessing the radiation exposure of civil aircrew. The current energy range of application for these devices is from 100 ke V to about 10 Me V. The possibility to extend the response of bubble detectors to higher energy netjtrons was experimentally investigated at the CERN-EU high-energy reference field racility by exposing the dosemeters inside lead converters of various thicknesses. Mpnte-Carlo calculations were performed to assess the effect of the lead converter on t~e neutron spectral fluence. The experimental results were compared with the calculated dose equivalent obtained by folding the response of the detectors with the modified neutron spectrum.
Sequence-Dependent Fluorescence of Cyanine Dyes on Microarrays (2011)

Cy3 and Cy5 are among the most commonly used oligonucleotide labeling molecules. Studies of nucleic acid structure and dynamics use these dyes, and they are ubiquitous in microarray experiments. They are sensitive to their environment and have higher quantum yield when bound to DNA. The fluorescent intensity of terminal cyanine dyes is also known to be significantly dependent on the base sequence of the oligonucleotide. We have developed a very precise and high-throughput method to evaluate the sequence dependence of oligonucleotide labeling dyes using microarrays and have applied the method to Cy3 and Cy5. We used light-directed in-situ synthesis of terminally-labeled microarrays to determine the fluorescence intensity of each dye on all 1024 possible 5'-labeled 5-mers. Their intensity is sensitive to all five bases. Their fluorescence is higher with 5' guanines, and adenines in subsequent positions. Cytosine suppresses fluorescence. Intensity falls by half over the range of all 5-mers for Cy3, and two-thirds for Cy5. Labeling with 5'-biotin-streptavidin-Cy3/-Cy5 gives a completely different sequence dependence and greatly reduces fluorescence compared with direct terminal labeling.
Blurring of local and remote practice models threatens IOM's future (2013)

In this issue of Neurology ® , Nuwer et al.1 present the results of a recent survey of American Academy of Neurology members concerning practice patterns for intraoperative neurophysiologic monitoring (IOM). The study confirms the continued growth of IOM but also sheds light on striking differences between 2 practice models—“local” monitoring and the “remote” telemetry. For historical reasons, a single Current Procedural Terminology (CPT) code has applied to both models, generating considerable ambiguity and resulting in lack of transparency, particularly to third-party payers, which now presents a serious challenge to the field and to neurologists providing IOM services. On November 1, 2012, with the issuance of the Centers for Medicare & Medicaid Services's (CMS's) Final Rule for Medicaid physician payments,2 this challenge became a crisis that threatens to limit IOM services available to Medicare patients.
Yolk Protein Immunoassays (YP-ELISA) to Assess Diet and Reproductive Quality of Mass-Reared <I>Orius insidiosus</I> (Heteroptera: Anthocoridae) (2002)

A yolk protein enzyme-linked immunosorbent assay (YP-ELISA) was developed for the predator Orius insidiosus (Say). The YP-ELISA is intended to assess reproductive response to dietary and other rearing conditions, and to assist in quality control and diet development for mass rearing. Hybridomas and monoclonal antibodies were produced against homogenates of eggs dissected from females. Hybridomas were selected for secretion of IgG that reacted with extracts of both females and their eggs, and that did not react with male extracts. Each cloned hybridoma produced a monoclonal antibody that specifically reacted on western blots against one of the two major yolk polypeptides, apoVn-I (180,000 molecular weight) or apoVn-II (40,000). Yolk protein ELISAs were developed with these antibodies to assess yolk protein content of female O. insidiosus as a measure of reproductive fitness and as a potential predictor of fecundity. Protocols for an indirect antigen ELISA and double antibody sandwich ELISA were developed to assess yolk protein contents of eggs and total contents in whole body homogenates. ELISA standards consisted of homogenates of eggs collected 0-24 h following oviposition. As determined with the sandwich ELISA, yolk protein contents of eggs declined with age before hatch, with a half-life of 32-34 h. Results were similar whether the detecting antibody-enzyme conjugate was anti-apoVn-I or anti-apoVn-II. Optimal conditions and sampling parameters were developed for the sandwich ELISA, which demonstrated minimal nonspecific interference in whole-insect extracts. In an initial application of the YP-ELISA, oviposition rates over a 10-d period were compared with yolk protein contents at the end of that period, dependent on diets of differing nutritional composition and quality. High and low yolk protein contents correlated with oviposition rates on respective diets, though oviposition showed more graded response to diets than did yolk protein. Improvements in sampling methods are discussed.
Motion of Rotating Superfluid Helium in an Annular Channel (1968)

A family of expressions is presented for the radial distribution of vortex lines in rotating helium II. This family is derived from asymptotic solutions to a differential equation proposed by Kemoklidze and Khalatnikov on the basis of the free-energy principle applied to a long, annular channel. The solutions are asymptotic in the sense that the quantum of circulation must be small compared to the circulation of a channel wall. The qualitative properties of the differential equation indicate that all solutions with positive vorticity and angular velocity of rotation are oscillatory. With increasing amplitude of oscillation, the solutions vary from the uniform vorticity distribution to distributions containing wide expanses free of vortex lines separated by narrow regions of high vortex-line density. This detailed analysis was necessary to determine whether a smooth transition could be achieved between a region of uniform vortex line density and a region of irrotational flow. The oscillatory solutions show that the answer is negative. Additionally, the oscillatory solutions are found to have high free energies, in agreement with the early analyses of London, of Landau and Lifshitz, and of Ginsburg.
Chromogenic Sensing of Biogenic Amines Using a Chameleon Probe and the Red−Green−Blue Readout of Digital Camera Images (2010)

We report on sensing spots containing an amine reactive chromogenic probe and a green fluorescent (amine insensitive) reference dye incorporated in a hydrogel matrix on a solid support. Such spots enable rapid and direct determination of primary amines and, especially, biogenic amines (BA). A distinct color change from blue to red occurs on dipping the test spots into a pH 9.0 sample containing primary amines. BAs can be determined in the concentration range from 0.01 to 10 mM within 15 min, enabling rapid, qualitative, and semiquantitative evaluation. In the “photographic” approach, the typically 4-7.5-fold increase in fluorescence intensity of the probe at 620 nm along with the constant green fluorescence at 515 nm of a reference dye are used for quantitation of BAs. The sensing spots are photoexcited with high-power 505 nm light-emitting diodes (LEDs) in a black box. A digital picture is acquired with a commercially available digital camera, and the color information is extracted via red-green-blue (RGB) readout. The ratio of the intensities of the red (signal) channel and the green (reference) channel yields pseudocolor pictures and calibration plots.

New profiled silicon photodetector for improved short-wavelength quantum efficiency (1979)

A new silicon-profiled ion-implanted n+-n−-p photodetector structure was developed for improved quantum efficiency in the visible spectrum. This device offers a significantly improved blue color response and it is compatible with CCD and MOSFET technologies. Experimental results show that the new device offers a quantum efficiency of more than 80% at 4000-Å wavelength relative to less than 1% quantum efficiency which a conventional n+-p silicon photodiode offers at the same wavelength. In addition, the present new device offers a flat quantum efficiency of more than 80% in the ultraviolet and entire visible spectrum (3800?λ?8000 Å). Also, the present device can be used as an efficient silicon solar cell.
Minimum Heating Energy Requirements of Piccolo Tube Jet Impingement Thermal Anti-Icing System (2007)

A numerical procedure for estimating the heating energy requirements for thermal anti-icing system design and analysis is presented. The leading edge geometry of an airfoil, exposed to atmospheric cloud containing a known sub-cooled water droplet size distribution, is analyzed and the surface temperature distribution required for anti-icing the airfoil surface is presented. The airfoil geometry flow field, computed using a compressible potential flow code, was utilized in the droplet trajectory code to calculate the local water collection efficiency. The collection efficiency and the surface velocity at the boundary layer edge are utilized in the thermal energy transfer rate calculation at the airfoil surface.
