Relative Permitivity Based Water-Cut Measurment Techniques for Permanent Downhole Applications in Multilateral Horizontal Wells (2015)

Abstract The challanges associated with efficient and reliable permanent downhole water cut measurement in multiphase flow and in multilateral horizontal well environment are described in this paper. The principles of relative permittivity based water-cut meters are explained in detail. A comprehensive analysis of the state-of-the-art relative permittivity based water cut measurement techniques are presented in this paper to evaluate their suitability for permanent downhole deployment. The techniques are compared against a set of requirements suitable for permanent downhole water cut measurement.
Variable Reluctance Magnetic Integrated Mini-Motor Fabrication And Test Results (2005)

Infroducfion: Small-size, highefficiency motors, fabricated by low cost batch fabrication techniques, are expected to have application in storage, automotive, medical and other fields. We describe a new approach to fabrication of an integrated experimental variable reluctance magnetic mini-motor, based on lithography and electroplating techniques, similar to those used in inductive head fabrication. Strumre Fabrication: The mini-motor consists of six, nearly planar, horseshoe-shaped electromagnets which surround a rotor. The stator diameter is 17 mm, rotor radius 2.976 mm, core width 0.7 mm, coil width 60 pm, and there are 120 turns per core., The motor thickness is -5OOpm, with a substrate approximately 1.0 mm. The fabrication sequence consists of a series of lithography, electroplating, seed layer removal, dielectric fill, and planarization steps. The process for the stator begins by sputterdepositing a Cu seed layer on an oxidized Si wafer, lithographically forming the plate-thru mask for the bottom part of the windings, and electroplating Cu through the mask. After removing the seed layer, a dielectric is applied across the entire structure, which is then planarized, and a pattemed dielectric is formed on top of the Cu to insulate the windings from the magnetic core. The Permalloy core is plated, and the top of the windings are formed by similar process steps. This simplifies the fabrication process. The vias that complete each tun of the coil are formed of PennaIloy during the core plating step. The rotor is fabricated by thru-mask plating of Permalloy on a separate substrate, detaching it, using a sacrificial layer, and then slipping it onto the pin. 'The pin is formed during the same lithography and plating steps thar created the core and the winding. Seed Layers: The seed layers for Cu and Permalloy plating respectively are of sputtered Ti/Cu (I 000-3000A) and of 1000-2OOOA sputtered Permalloy (80120) NiFe).
Simulation of kicker pulser with MATLAB simulink (2002)

The pulser system of kicker magnet in Synchrotron Radiation Research Center (SRRC) is a 25 kV in-house-designed high voltage system which generates a pulse current to steer the injected beam from booster ring into storage ring. The injection efficiency is strongly influenced by the performance of this pulser. It is very difficult and dangerous to measure and modify the circuit inside of pulser because of high voltage environment. Before any performance improvement, simulation of circuitry of this pulser with MATLAB Simulink is a safe way to understand the behavior of every component. Model of such system will be demonstrated and modification of such system will become easier for future applications.
Defining the Catalytic Activity of Nanoceria in the P23H-1 Rat, a Photoreceptor Degeneration Model (2015)

We validated that CeNPs were effective in delaying loss of photoreceptor cell function in an adRP rat model. This represents the fourth rodent retinal disease model that shows delay in disease progression after a single application of CeNPs. We further demonstrated that CeNPs slowed the rate of photoreceptor cell death. We deduced that the catalytic activity of CeNPs in vivo in this rat model to be undiminished for at least 7 days and then declined over the next 14 days after CeNPs administration.
Ethylene Oligomerization and Polymerization by Palladium(II) Methyl Complexes Supported by Phosphines Bearing a Perchlorinated 10-Vertex closo-Carborane Anion Substituent (2018)

The synthesis and ethylene reactivity of the zwitterionic Pd methyl complexes (κ2-P,Cl-PR2CB9Cl9)PdMe(THF) (7, R = iPr; 8, R = Ph) and (κ2-P,O-P(o-OMe-Ph)2CB9Cl9)PdMe(THF) (9), which contain the first phosphines appended with anionic 10-vertex perchlorinated closo-carboranes, are described. Complexes 7 and 8 oligomerize ethylene (23 °C, 2 atm) to a Schulz–Flory distribution of C4–C10 olefins with TOFs of ca. 8000 and 1800 t.o./h, respectively. 8 is ca. 4 times more active than the analogous (κ2-P,F-ortho-PPh2C6H4BF3)PdMe(L) (L = pyridine or collidine) system reported by Jordan and Piers, which produces butenes. Complex 9 reacts with ethylene to yield polyethylene wax (Mn ca. 1000, Đ ca. 1.5) that is similar to commercial Fischer–Tropsch waxes. The activities of 7–9 are independent of ethylene pressure and the presence of B(C6F5)3, suggesting that the catalyst resting state is the corresponding (PR2CB9Cl9)PdR(H2C═CH2) adduct. The molecular weights of the oligomer/polymer products are independent of ethylene pressure, which is consistent with an associative chain transfer mechanism. Reaction of 9 with ethylene generates the corresponding ethylene complex (κ2-P,O-P(o-OMe-Ph)2CB9Cl9)PdMe(H2C═CH2), which inserts ethylene at −20 °C with a barrier (ΔG⧧insertion) of 18.1 kcal/mol.
Propellant-Assisted Perforating in Tight-Gas Reservoirs: Wireline Formation Tests Show Successful Stimulation (2010)

Abstract Propellant-assisted perforating systems are used to stimulate the near wellbore region and to alleviate the formation compaction damage from the perforating event. This method involves combining a perforating gun with a high pressure, gas generating propellant. Detonation of the perforating gun causes the propellant to deflagrate. The resulting combustion gas enters the newly created perforations. This breaks down the compacted region and extends a fracture network from the perforation tunnels. Wireline formation testing has demonstrated the capability of this perforating method to stimulate beyond the depth of drilling and cementing invasion, especially in tight-gas reservoirs. The wireline formation testing system is often referred to as a mini drillstem test (DST). It is conveyed into the well on wireline and it uses a dual packer assembly to isolate the perforated interval. With the pump-out capability of the tool, multiple drawdown and buildup cycles are performed. Pressure transient analysis (PTA) is applied to the measured pressure data to evaluate near-wellbore reservoir characteristics. Depending on the formation parameters, there are two extreme responses observed in these tests: a radial composite model; or a linear fracture model. The radial composite model represents a higher permeability region in the near-wellbore area, surrounded by a lower permeability outer region representing the formation matrix. The typical radius for the inner region is up to 3 m. The linear fracture model represents a small fracture into the formation, generally with a fracture half-length of 1 to 2 m. In reality often a combination of the two models is more representative. All responses show less resistance to flow in the near-wellbore area, representing a positive cleanup and stimulation. Modeling indicates that the propellant-assisted perforation systems are capable of penetrating beyond any induced damage. This is often not the case when using conventional perforation charges. This study comprehends 50 wireline formation tests in tight-gas reservoirs. These tests are used to demonstrate the successful application of propellant-assisted perforating techniques and to illustrate the different pressure responses created by propellant-assisted perforating in the near-wellbore area. The results are also compared to pre-job propellant stimulation modeling software analysis.
<title>Update on INCITS W1.1 standard for evaluating the color rendition of printing systems</title> (2003)

The color rendition <i>ad hoc</i> team of INCITS W1.1 is working to address issues related to color and tone reproduction for printed output and its perceptual impact on color image quality. The scope of the work includes accuracy of specified colors with emphasis on memory colors, color gamut, and the effective use of tone levels, including issues related to contouring. The team has identified three sub-attributes of color rendition: (1) color quantization -- defined as the ability to merge colors where needed, (2) color scale -- defined as the ability to distinguish color where needed, and (3) color fidelity -- defined as the ability to match colors. Visual definitions and descriptions of how these sub-attributes are perceived have been developed. The team is presently defining measurement methods for these, with the first of the sub-attributes considered being color quantization. More recently, the problem of measuring color fidelity has been undertaken. This presentation will briefly review the definitions and appearance of the proposed sub-attributes. The remainder of the discussion will focus on the progress to date of developing test targets and associated measurement methods to quantify the color quantization and color fidelity sub-attributes.

X-ray crystallography firmly established the relative stereochemistry of the title compound, C16H20N2O3. The acetonide ring adopts an envelope conformation with one of the O atoms as the flap and the piperidine ring adopts a slightly twisted boat conformation. The absolute configuration was determined by use of d-ribose as the starting material. The compound exists as O-H⋯O hydrogen-bonded chains of mol-ecules running parallel to the b axis.
Statistical Program Slicing: a Hybrid Slicing Technique for Analyzing Deployed Software (2021)

Dynamic program slicing can significantly reduce the code developers need to inspect by narrowing it down to only a subset of relevant program statements. However, despite an extensive body of research showing its usefulness, dynamic slicing is still short from production-level use due to the high cost of runtime instrumentation. As an alternative, we propose statistical program slicing, a novel hybrid dynamic-static slicing technique that explores the trade-off between accuracy and runtime cost. Our approach relies on modern hardware support for control flow monitoring and a novel, cooperative heap memory tracing mechanism combined with static program analysis for data flow tracking. We evaluate statistical slicing for debugging on 21 failures from 6 widely deployed applications and show it recovers 94% of the program statements on a dynamic slice with only 5% overhead.
Aspect ratio effects of multi‐walled carbon nanotubes on electrical, mechanical, and thermal properties of polycarbonate/MWCNT composites (2013)

ABSTRACT Two multi‐walled carbon nanotubes (MWCNTs) having relatively high aspect ratios of 313 and 474 with approximately the same diameter were melt mixed with polycarbonate (PC) in a twin‐screw conical micro compounder. The effects of aspect ratio on the electrical, mechanical, and thermal properties of the PC/MWCNT composites were investigated. Electrical conductivities and storage moduli of the filled samples are found to be independent of the starting aspect ratio for these high aspect ratio tubes; although the conductivities and storage moduli are still significantly higher than values of composites made with nanotubes having more commercially common aspect ratios of ∼100. Transmission electron microscopy results suggest that melt‐mixing reduces these longer nanotubes to the same length, but still approximately two times longer than the length of commercially common aspect ratio tubes after melt‐mixing. Molecular weight measurements show that during melt‐mixing the longer nanotubes significantly degrade the molecular weight of the polymer as compared to very similar nanotubes with aspect ratio ∼100. Because of the molecular weight reduction glass transition temperatures predictably show a large decrease with increasing nanotube concentration. © 2013 Wiley Periodicals, Inc. J. Polym.

3D imaging via silicon-photonics-based LIDAR (2021)

Accurate 3D imaging is essential for machines to map and interact with the physical world1,2. While numerous 3D imaging technologies exist, each addressing niche applications with varying degrees of success, none have achieved the breadth of applicability and impact that digital image sensors have achieved in the 2D imaging world3-10. A large-scale twodimensional array of coherent detector pixels operating as a light detection and ranging (LIDAR) system could serve as a universal 3D imaging platform. Such a system would other high depth accuracy and immunity to interference from sunlight, as well as the ability to directly measure the velocity of moving objects11. However, due to difficulties in providing electrical and photonic connections to every pixel, previous systems have been restricted to fewer than 20 pixels12-15. Here, we demonstrate the first large-scale coherent detector array consisting of 512 (32×16) pixels, and its operation in a 3D imaging system. Leveraging recent advances in the monolithic integration of photonic and electronic circuits, a dense array of optical heterodyne detectors is combined with an integrated electronic readout architecture, enabling straightforward scaling to arbitrarily large arrays. Meanwhile, two-axis solid-state beam steering eliminates any tradeoff between field of view and range. Operating at the quantum noise limit16,17, our system achieves an accuracy of 3.1 mm at a distance of 75 meters using only 4 mW of light, an order of magnitude more accurate than existing solid-state systems at such ranges. Future reductions of pixel size using state-of-the-art components could yield resolutions in excess of 20 megapixels for arrays the size of a consumer camera sensor. This result paves the way for the development and proliferation of low cost, compact, and high-performance 3D imaging cameras, enabling new applications from robotics and autonomous navigation to augmented reality and healthcare.

Avoiding ambient air in test tubes during incubations of human whole-blood minimizes complement background activation (2020)

Avoiding air in test tubes during whole-blood experiments reduced background complement activation substantially and represents an important improvement to the lepirudin whole-blood model. This could also apply to other in vitro models.
Properties of Dicationic Disiloxane Ionic Liquids (2020)

A number of dicationic ionic liquids with a disiloxane linker between imidazolium cations and bis(trifluoromethylsulfonyl)imide anion were synthesized and characterized. Melting points, viscosity, and volatility in a vacuum were measured; the thermal and hydrolytic stability of ionic liquids were also studied. The dependence of the properties on the structure of substituents in the cation of the ionic liquid was demonstrated.
Quasi-CW Room Temperature Operation of 1.52 µm InGaAsP/AlGaAs Vertical Cavity Lasers Obtained by Localised Fusion (1998)

1.52 µm double fused InGaAsP/AlGaAs vertical cavity surface emitting lasers with in-situ built-in lateral current confinement were fabricated using localised wafer fusion process. These devices operate at room temperature in quasi-CW regime at 10% duty cycle. Operation characteristics of these lasers are limited by the high resistivity of p-InP/p-GaAs fused junctions which is a result of using carbon-doped p-AlGaAs/GaAs distributed Bragg-mirrors.

Abstract Reaction of tetramethylsuccinicdinitrile with methylmagnesium iodide in boiling toluene leads to the title compound 8 in 80–85% yield. The magnesium complex of 2‐imino‐3,3,4,4‐tetramethyl‐5‐methylidene‐pyrrolidine is shown to act as an intermediate.
Lazy Network: A Word Embedding‐Based Temporal Financial Network to Avoid Economic Shocks in Asset Pricing Models (2022)

Public companies in the US stock market must annually report their activities and financial performances to the SEC by filing the so‐called 10‐K form. Recent studies have demonstrated that changes in the textual content of the corporate annual filing (10‐K) can convey strong signals of companies’ future returns. In this study, we combine natural language processing techniques and network science to introduce a novel 10‐K‐based network, named Lazy Network, that leverages year‐on‐year changes in companies’ 10‐Ks detected using a neural network embedding model. The Lazy Network aims to capture textual changes derived from financial or economic changes on the equity market. Leveraging the Lazy Network, we present a novel investment strategy that attempts to select the least disrupted and stable companies by capturing the peripheries of the Lazy Network. We show that this strategy earns statistically significant risk‐adjusted excess returns. Specifically, the proposed portfolios yield up to 95 basis points in monthly five‐factor alphas (over 12% annually), outperforming similar strategies in the literature.

Opioid Receptor-Like 1 (ORL1) Molecular &#x201C;Road Map&#x201D; to Understanding Ligand Interaction and Selectivity (2005)

The opioid receptor-like 1 (ORL1) system has attracted a lot of attention owing to its diverse physiological role and by its close structural proximity toward the classical opioid receptors. Even though they share a close sequence similarity, the ligand recognition pattern for the ORL1 receptor and the classical opioid receptors remains highly distinct. In addition, functional diversification observed between the ORL1 receptor system and classical opioid receptors clearly indicates that subtle changes in the structural makeup of a receptor are enough to delineate them. A clear understanding of the structural requirements for ligand selectivity by classical opioid receptors and identification of a common "opioid binding pocket" has not been achieved yet. At this juncture, the ORL1 receptor system presents itself as a potential tool in the quest for elucidating critical elements directing ligand selectivity. The current paper is a compilation of several site-directed mutagenesis studies conducted on the ORL1 receptor system. The mutagenesis studies concentrated on the transmembrane domain residues are reported with the changes observed in terms of both binding and functional activation of the receptor. Given the critical role played by this G-protein coupled receptor, molecular level understanding of this ORL1 receptor system would aid in rational design and development of agonists and antagonists with multiple therapeutic applications.
Developmental Regulation of GlutathioneS-Transferases (1988)

1. cDNA probes for individual isoenzymes of rat glutathione S-transferases were used to determine steady state levels of their mRNAs in liver and brain during development. 2. Foetal livers were enriched in Yp transcripts (that are characteristic of hyperplastic nodules and hepatocellular carcinomas), but these forms decreased after the first week of postnatal development and were not detected in adult livers. In contrast, in adult brains Yp levels increased. 3. Ya forms that were present at low levels in foetal and neonatal livers, increased markedly during development. Ya was not detected in brain. 4. The Yb1 and Yb2 GSTs were present in higher amounts than Ya in foetal livers, and these isoenzymes also increased in adults.
Benzene migration in an osmium cluster: the formation of Os3(CO)7(η6-C6H6)(µ3: η1: η2: η1-C2Me2) from Os3(CO)9(µ3: η2: η2: η2-C6H6). The crystal structure of Os3(CO)7(η6-C6H6)(µ3: η1: η2: η1-C2Me2) (1990)

The activated cluster [Os3(CO)7(C2H4)(µ3 : η2 : η2 : η2-C6H6)(MeCN)] reacts with alkynes RC2R′(R = R′= H, Ph or Me; R = H, R′= Ph; R = ME, R′= Et), to produce the new clusters [OS3(CO)7(η6-C6H6)(µ3 : η1 : η2 : η1-RC2R′)] in which the benzene is bonded to a single metal atom as shown by a single crystal X-ray structure determination of the C2Me2 derivative.
