3D Localization of weak scatterers in digital holographic microscopy using Rayleigh-Sommerfeld back-propagation (2012)

The Rayleigh-Sommerfeld back-propagation method is a fast and highly flexible volume reconstruction scheme for digital holographic microscopy. We present a new method for 3D localization of weakly scattering objects using this technique. A well-known aspect of classical optics (the Gouy phase shift) can be used to discriminate between objects lying on either side of the holographic image plane. This results in an unambiguous, model-free measurement of the axial coordinate of microscopic samples, and is demonstrated both on an individual colloidal sphere, and on a more complex object — a layer of such particles in close contact.
Laboratory Tests on Heavy Oil Recovery by Steam Injection (1983)

Abstract This paper presents results of laboratory experiments conducted to determine the effect of various parameters on residual oil saturation from steamdrives of heavy-oil reservoirs. These experiments indicated that remaining oil saturation, both at steam breakthrough and after passage of several PV of steam, is a function of oil/water viscosity ratio at saturated steam conditions.

A growing machine learning approach to optimize use of prestack and poststack seismic data (2017)

Machine Learning and Neural Networks have been used in the oil and gas industry for several years. The main focus of these technologies has been to predict facies distribution from seismic data, or to cluster log data into electro-facies. Some tentative methods for expanding their applicability have been tested, but to date, these have failed to become part of the main interpretation workow stream. The question is how machine learning technology can be used to perform fault interpretation, AVO analysis and geobody detection more quickly and easily. We propose a new type of machine learning approach to accelerate daily interpretation tasks.

Clinical laboratory: enzyme immunoassay for the rapid clinical identification of snake venom. (1980)

The treatment of snakebite could be simplified if the identity of the offending snake was more frequently known. A positive identification, which allows the use of a specific monovalent antivenom, probably occurs in less than 20% of cases. Recently published methods of venom detection (RIA and ELISA) take at least three hours to complete. We have developed a sandwich enzyme immunoassay (EIA) which is capable of detecting 0.5 ng of crude snake venom in about 90 minutes or 2 ng of crude venom in about 30 minutes. This substantial reduction in incubation times, while still retaining the sensitivity required, was due to the use of protein A purified rabbit IgG antivenom from hyperimmune serum and the enzyme horseradish peroxidase (HRPO). A rapid identification of the offending snake by this method may reduce the use of large-volume polyvent antivenoms, thus avoiding the clinical and economic disadvantages of such preparations. Other advantages would be an increased understanding of the clinical syndrome produced by the individual species of snake, and accumulation of data about the incidence of envenoming attributed to specific snakes.

Characterization of the Oxygen-Responsive NreABC Regulon of <i>Staphylococcus aureus</i> (2008)

Here, we investigate the functionality of the oxygen-responsive nitrogen regulation system NreABC in the human pathogen Staphylococcus aureus and evaluate its role in anaerobic gene regulation and virulence factor expression. Deletion of nreABC resulted in severe impairment of dissimilatory nitrate and nitrite reduction and led to a small-colony phenotype in the presence of nitrate during anaerobic growth. For characterization of the NreABC regulon, comparative DNA microarray and proteomic analyses between the wild type and nreABC mutant were performed under anoxic conditions in the absence and presence of nitrate. A reduced expression of virulence factors was not observed in the mutant. However, both the transcription of genes involved in nitrate and nitrite reduction and the accumulation of corresponding proteins were highly decreased in the nreABC mutant, which was unable to utilize nitrate as a respiratory oxidant and, hence, was forced to use fermentative pathways. These data were corroborated by the quantification of the extracellular metabolites lactate and acetate. Using an Escherichia coli-compatible two-plasmid system, the activation of the promoters of the nitrate and nitrite reductase operons and of the putative nitrate/nitrite transporter gene narK by NreBC was confirmed. Overall, our data indicate that NreABC is very likely a specific regulation system that is essential for the transcriptional activation of genes involved in dissimilatory reduction and transport of nitrate and nitrite. The study underscores the importance of NreABC as a fitness factor for S. aureus in anoxic environments.

A General Failure Criterion for Spot Welds with Consideration of Plastic Anisotropy and Separation Speed (2003)

<div class="htmlview paragraph">A general failure criterion for spot welds is proposed with consideration of the plastic anisotropy and the separation speed for crash applications. A lower bound limit load analysis is conducted to account for the failure loads of spot welds under combinations of three forces and three moments. Based on the limit load solution and the experimental results, an engineering failure criterion is proposed with correction factors determined by different spot weld tests. The engineering failure criterion can be used to characterize the failure loads of spot welds with consideration of the effects of the plastic anisotropy, separation speed, sheet thickness, nugget radius and combinations of loads. Spot weld failure loads under uniaxial and biaxial opening loads and those under combined shear and twisting loads from experiments are shown to be characterized well by the engineering failure criterion.</div>
Concatenated Power Mean Word Embeddings as Universal Cross-Lingual\n Sentence Representations (2018)

Average word embeddings are a common baseline for more sophisticated sentence\nembedding techniques. However, they typically fall short of the performances of\nmore complex models such as InferSent. Here, we generalize the concept of\naverage word embeddings to power mean word embeddings. We show that the\nconcatenation of different types of power mean word embeddings considerably\ncloses the gap to state-of-the-art methods monolingually and substantially\noutperforms these more complex techniques cross-lingually. In addition, our\nproposed method outperforms different recently proposed baselines such as SIF\nand Sent2Vec by a solid margin, thus constituting a much harder-to-beat\nmonolingual baseline. Our data and code are publicly available.\n
Percutaneous Peritoneal Lavage Using the Veress Needle (1987)

A modification of past percutaneous methods for peritoneal lavage is described which combines the safety of the Veress Needle with the utility of a readily available introducer-dilator catheter. The technique has been used in 30 patients seen for blunt abdominal trauma and has been found to be a reliable and accurate method for peritoneal lavage.
Study of the radical mechanism of iodine‐catalyzed isomerization of conjugated diene systems (1989)

Abstracts The iodine‐catalyzed Z/E‐isomerization of internal conjugated dienes in the dark, to form a thermodynamic equilibrium mixture, was found to be a radical process with an activation energy of 12.4±1.2 kcal/ mol. The effects of antioxidants on the reaction, both in the dark and in sunlight, were studied. In both processes the radical isomerization was slowed down, probably through radical scavenging.
Characterization of mini-protein S, a recombinant variant of protein S that lacks the sex hormone binding globulin-like domain (1998)

Protein S is a vitamin K-dependent glycoprotein involved in the regulation of the anticoagulant activity of activated protein C (APC). Also, an anticoagulant role for protein S, independent of APC, has been described. Protein S has a unique C-terminal sex hormone binding globulin (SHBG)-like domain that represents about half of the molecule. To define the role of this domain in APC cofactor activity and in binding to C4b-binding protein (C4BP), we have constructed a recombinant protein S molecule of N-terminal residues 1-242 that lacks the SHBG domain (mini-protein S). A panel of monoclonal antibodies directed against the N-terminal region of protein S recognized plasma-derived protein S, wild-type recombinant protein S and mini-protein S with similar affinities, whereas a monoclonal antibody that recognizes an epitope in the SHBG domain did not detect mini-protein S. Mini-protein S did not bind to C4BP in a solid-phase binding assay, and the cofactor activity of mini-protein S was not inhibited by preincubation with C4BP. In a plasma coagulation assay, the cofactor activity of mini-protein S was lower than wild-type or plasma-derived preparations. In contrast, no difference in APC cofactor activities was observed when the preparations were tested in purified systems that monitor the APC-mediated degradation of factors Va or VIIIa. In conclusion, we constructed a protein S molecule that fails to bind C4BP and still displays cofactor activity for APC. This confirms the role of the C-terminal SHBG region in C4BP binding and demonstrates that N-terminal residues 1-242 are sufficient for the expression of APC cofactor activity in a system using purified components. In plasma, however, the C-terminal SHBG region plays a role in the expression of optimal APC cofactor activity.
Highly Reflective Ag∕La Bilayer Ohmic Contacts to p-Type GaN (2011)

A new bilayer metal contact scheme has been developed for producing high reflectance and low contact resistivity ohmic contacts to p-GaN. An excellent reflectance of over 91% at wavelength and low specific contact resistivity of were obtained from contact annealed at for . The La overlayer was oxidized to form when exposed to air, which effectively suppresses exposure of the Ag layer to oxygen atmosphere during annealing, leading to a good ohmic contact with smooth surface morphology and high reflectance. Additionally, contacts show excellent thermal stability after a long thermal annealing at in air ambient.

Manufacturing of metallic porous structures to be used in capillary pumping systems (2003)

Sintered metallic porous structures have an application as capillary structures in two-phase heat transfer loops. In this work the manufacturing procedure of tubular porous structures for capillary pump application is discussed. The application of porous structures on capillary pumping systems requires porosity higher than 40% and pore size diameter lower than 20 µm. Carbonyl nickel powder with particle diameter between 3 and 7 µm and stainless steel AISI316L powder with particle diameter between 1 and 22 µm were used as raw material. Sintering under hydrogen atmosphere was performed both in a resistive furnace and in a plasma reactor. Temperature and time were the modified parameters to obtain suitable porosity and roundness on the samples. The porosity was measured using the Arquimedes Principle (MPIF-42), the roundness was evaluated using a simplified measurement technique of the sample diameter and the pore size distribution was determined by image analysis techniques. Images obtained by Scanning Electronic Microscopy were employed on the image analysis. The sintering parameters selected to manufacture nickel samples were 700 °C and 30 min resulting in a porosity of about 44%. The sintering parameters selected to manufacture stainless steel samples were 1000 °C and 30 min resulting in a porosity of about 40%.
Melt Rheology of Polymer Blends from Melt Flow Index (1984)

Abstract Polymer blends have received a lot of attention in recent years due to the possibility of getting compounds with novel and/or different properties through proper marriage of the properties of the respective mono-components. The flow behaviour of blends when subjected to stresses is complex and is often found not to vary monotonically with composition. Mixing rules and mixture theories have been used for estimating melt viscosity of a blend at zero shear rate. However a knowledge of the entire rheogram is desirable for process optimization, process design and trouble shooting. In the present paper a method proposed earlier to estimate the rheograms of polymer melts through the use of the melt flow index has been extended to polyblends. A method for obtaining the melt flow index of the polymer blends at various compositions from the melt flow index of the individual components and the blend ratio has been suggested based on the altered free volume state model. Curves that are coalesced using the melt flow index of the blend at different blend ratios have been presented for a polypropylene-high density polyethylene blend, a high density polyethylene-polymethyl methacrylate blend, a polystyrene-polymethyl-methacrylate blend, a polystyrene-polyacetal blend and a polymethylmethacrylate-polyacetal blend.
Sensor network paradigms for structural health monitoring (2005)

Structural health monitoring (SHM) is the process of detecting damage in structures. The goal of SHM is to improve the safety and reliability of aerospace, civil and mechanical infrastructure by detecting damage before it reaches a critical state. A specific topic that has not been extensively addressed in the SHM literature is the development of rigorous approaches to designing the SHM sensing system that is used to address the data acquisition portion of the problem. To date, almost all such system designs are done somewhat in an ad hoc manner where the engineer picks a sensing system that is readily available and that they are familiar with, and then attempts to demonstrate that a specific type of damage can be detected with that system. In many cases this approach has been shown to be ineffective and as a result researchers have begun to develop sensor networks specially suited for SHM. Based on this research, several sensor network paradigms for SHM have emerged, and this paper is intended to provide an overview of these paradigms. This paper will first provide a brief summary of the statistical pattern recognition approach to SHM problem. The data acquisition portion of the paradigm is then addressed in detail where the various parameters of the system that must be considered in its design and subsequent field deployment are summarized.

A new organometallic synthesis of size-controlled tin(0) nanoparticles (2005)

Tin(0) nanoparticles have been prepared by a new low temperature chemical reduction of SnCl4 with t-BuONa activated NaH in THF. The size and the crystallinity of the particles can be controlled by adjusting the reaction time. Subnanometrical and amorphous Sn(0) particles were produced after 1 h reaction at 65 °C. Tetragonal Sn(0) particles with diameters of 3.2 and 40.0 nm were respectively prepared by further heating for 1 and 3.5 h. The colloidal solutions thus produced are stable at room temperature for long periods of time. Sn nanoparticles were characterized by transmission electron microscopy, XPS and EDS analyses and x-ray powder diffraction.
HORSE SPECIES SYMPOSIUM: A novel approach to monitoring pathogen progression during uterine and placental infection in the mare using bioluminescence imaging technology and lux-modified bacteria1,2 (2011)

Uterine and placental infections are the leading cause of abortion, stillbirth, and preterm delivery in the mare. Whereas uterine and placental infections in women have been studied extensively, a comprehensive examination of the pathogenic processes leading to this unsatisfactory pregnancy outcome in the mare has yet to be completed. Most information in the literature relating to late-term pregnancy loss in mares is based on retrospective studies of clinical cases submitted for necropsy. Here we report the development and application of a novel approach, whereby transgenically modified bacteria transformed with lux genes of Xenorhabdus luminescens or Photorhabdus luminescens origin and biophotonic imaging are utilized to better understand pathogen-induced preterm birth in late-term pregnant mares. This technology uses highly sensitive bioluminescence imaging camera systems to localize and monitor pathogen progression during tissue invasion by measuring the bioluminescent signatures emitted by the lux-modified pathogens. This method has an important advantage in that it allows for the potential tracking of pathogens in vivo in real time and over time, which was hitherto impossible. Although the application of this technology in domestic animals is in its infancy, investigators were successful in identifying the fetal lungs, sinuses, nares, urinary, and gastrointestinal systems as primary tissues for pathogen invasion after experimental infection of pregnant mares with lux-modified Escherichia coli. It is important that pathogens were not detected in other vital organs, such as the liver, brain, and cardiac system. Such precision in localizing sites of pathogen invasion provides potential application for this novel approach in the development of more targeted therapeutic interventions for pathogen-related diseases in the equine and other domestic species.
Measuring auditory selective attention using frequency tagging (2014)

Frequency tagging of sensory inputs (presenting stimuli that fluctuate periodically at rates to which the cortex can phase lock) has been used to study attentional modulation of neural responses to inputs in different sensory modalities. For visual inputs, the visual steady-state response (VSSR) at the frequency modulating an attended object is enhanced, while the VSSR to a distracting object is suppressed. In contrast, the effect of attention on the auditory steady-state response (ASSR) is inconsistent across studies. However, most auditory studies analyzed results at the sensor level or used only a small number of equivalent current dipoles to fit cortical responses. In addition, most studies of auditory spatial attention used dichotic stimuli (independent signals at the ears) rather than more natural, binaural stimuli. Here, we asked whether these methodological choices help explain discrepant results. Listeners attended to one of two competing speech streams, one simulated from the left and one from the right, that were modulated at different frequencies. Using distributed source modeling of magnetoencephalography results, we estimate how spatially directed attention modulates the ASSR in neural regions across the whole brain. Attention enhances the ASSR power at the frequency of the attended stream in contralateral auditory cortex. The attended-stream modulation frequency also drives phase-locked responses in the left (but not right) precentral sulcus (lPCS), a region implicated in control of eye gaze and visual spatial attention. Importantly, this region shows no phase locking to the distracting stream. Results suggest that the lPCS in engaged in an attention-specific manner. Modeling results that take account of the geometry and phases of the cortical sources phase locked to the two streams (including hemispheric asymmetry of lPCS activity) help to explain why past ASSR studies of auditory spatial attention yield seemingly contradictory results.
