ESP Well Surveillance using Pattern Recognition Analysis, Oil Wells, Petroleum Development Oman (2014)

Abstract PDO is managing some 850 Electrical Submersible Pump (ESP) systems scattered across North & South fields, which is continue to grow in the next five years business plan. All ESP wells have real time down-hole sensors that measures intake and discharge pressures, intake and motor temperatures, vibration and current leakage. The oil producing fields are equipped with real time data transmission system where several data measurements; down hole (such as pump intake and discharge pressures and temperatures) and surface (such as volts, amps and frequency) are transmitted directly from the well site to the gathering stations, central control rooms and even to the engineers' desktop. At present, PDO is deploying an integrated smart tool which will monitor, control, and optimize oil production and ESP performance to the various disciplines involved in oil production and optimization like Reservoir and Petroleum Engineers, Programmers, and Field Operation Teams. However, in order to enable these modern well surveillance systems, which often produce an overwhelming quantity of information but the data is often misleading or difficult to interpret, establishing the Pattern recognition of the trended real time data is key to make the software intelligent enough to be effective to the work places. This paper will demonstrate how precise ESP, well and reservoir performance can be predicted from simple physical relationships and how these relate to the trends of surface and downhole data. A number of real field examples of data trends will be shown to illustrate how a proper understanding of these patterns will allow prompt ESP troubleshooting and ensure the correct actions are taken. The results are correlated with equipment pull and inspection reports to validate the diagnosis. Pattern recognition trends and analysis will be presented for common problems such as hole in tubing, shut in at surface, ESP wear, blockage at pump intake, debris in pump, broken shaft, change in reservoir pressure, blockage at perforations, etc. A proper understanding of these trends will allow the correct settings of alarm and trips and assist in the implementation of semi-automated well surveillance and diagnostic system which being currently deployed in the Company. A pattern recognition analysis check sheet will be included in the paper to allow users to quickly interpret data trends and diagnose well, ESP and reservoir performance problems.
<i>aubergine</i>encodes a<i>Drosophila</i>polar granule component required for pole cell formation and related to eIF2C (2001)

In Drosophila oocytes, activation of Oskar translation from a transcript localized to the posterior pole is an essential step in the organization of the pole plasm, specialized cytoplasm that contains germline and abdominal body patterning determinants. Oskar is a component of polar granules, large particles associated with the pole plasm and the germline precursor pole cells of the embryo. aubergine mutants fail to translate oskar mRNA efficiently and are thus defective in posterior body patterning and pole cell formation. We have found that Aubergine protein is related to eukaryotic translation initiation factor 2C and suggest how it may activate translation. In addition, we found that Aubergine was recruited to the posterior pole in a vas-dependent manner and is itself a polar granule component. Consistent with its presence in these structures, Aubergine is required for pole cell formation independently of its initial role in oskar translation. Unlike two other known polar granule components, Vasa and Oskar, Aubergine remains cytoplasmic after pole cell formation, suggesting that the roles of these proteins diverge during embryogenesis.
BlockchainDB - Towards a Shared Database on Blockchains (2019)

In this demo we present BlockchainDB, which leverages blockchains as storage layer and introduces a database layer on top that extends blockchains by classical data management techniques (e.g., sharding). Further, BlockchainDB provides a standardized key/value-based query interface to facilitate the adoption of blockchains for data sharing use cases. With BlockchainDB we can thus not only improve the performance and scalability of blockchains for data sharing but also decrease the complexity for organizations intending to use blockchains for this use case.
Immunologic cross-reactivity of type A streptococcal exotoxin (erythrogenic toxin) and staphylococcal enterotoxins B and C1 (1987)

Immunologic cross-reactivity between Streptococcus pyogenes type A exotoxin (erythrogenic toxin) and Staphylococcus aureus enterotoxins B and C1 was demonstrated by Ouchterlony double diffusion, Western immunoblot, and immunodot analyses. Specific antiserum to type A streptococcal exotoxin reacted more strongly with staphylococcal enterotoxin B than with enterotoxin C1. The reactivity of type A streptococcal exotoxin with antiserum to staphylococcal enterotoxin B was greater than that of antiserum to enterotoxin C1. These results suggest that a conserved domain is present in the three exotoxins, which most likely originated from a common evolutionary ancestor.
A new and effective fuzzy PID autopilot for ships (2003)

This paper presents a new method for constructing a ship autopilot based on the combination of fuzzy logic control (FLC) and linear control theory (PID control). Simulation using Matlab software for a ship with real parameters shows high effectiveness of the fuzzy PID autopilot during course keeping and course changing maneuvers in comparison with the ordinary PID ship autopilots.
Research on On-line Monitoring Technology of Pressure Drop in Secondary Circuit of Voltage Transformer and Directional Push Technology of Alarm Information (2018)

Traditional energy metering technology cannot monitor energy metering devices which number has been growing in real time and realize timely notification of alarm information, so it is difficult to effectively control the occurrence of metering accidents and reduce the amount of power. Through the analysis of the metering circuit, this article provides real-time monitoring the secondary circuits of voltage transformers which are the most error-prone. Ensure that the alarm information can be promptly notified when the voltage loss of the power meter and the secondary pressure drop are exceeded. And use a more stable operation board to reduce the occurrence of secondary circuit open-circuit faults. Finally, the practicality of the technology was verified through experiments.
Multiple Roles of CLAN (Caspase-Associated Recruitment Domain, Leucine-Rich Repeat, and NAIP CIIA HET-E, and TP1-Containing Protein) in the Mammalian Innate Immune Response (2004)

NAIP CIIA HET-E and TP1 (NACHT) family proteins are involved in sensing intracellular pathogens or pathogen-derived molecules, triggering host defense responses resulting in caspase-mediated processing of proinflammatory cytokines and NF-kappaB activation. Caspase-associated recruitment domain, leucine-rich repeat, and NACHT-containing protein (CLAN), also known as ICE protease-activating factor, belongs to a branch of the NACHT family that contains proteins carrying caspase-associated recruitment domains (CARDs) and leucine-rich repeats (LRRs). By using gene transfer and RNA-interference approaches, we demonstrate in this study that CLAN modulates endogenous caspase-1 activation and subsequent IL-1beta secretion from human macrophages after exposure to LPS, peptidoglycan, and pathogenic bacteria. CLAN was also found to mediate a direct antibacterial effect within macrophages after Salmonella infection and to sensitize host cells to Salmonella-induced cell death through a caspase-1-independent mechanism. These results indicate that CLAN contributes to several biological processes central to host defense, suggesting a prominent role for this NACHT family member in innate immunity.
Identification and study of differentially expressed miRNAs in aged NAFLD rats based on high-throughput sequencing (2019)

A total of 10 DE-miRs identified in the aged NAFLD rats were involved in some certain insulin secretion and age-related functional pathways, which may serve as novel candidate targets for the diagnosis and treatment of aging-associated NAFLD.
An Overview — Solvents for Agricultural Chemicals (1989)

Solvents and petroleum oils have been used in agricultural chemicals for over one hundred years, and this paper presents an overview of the solvents and oils typically used in ag chem today. It includes discussion on solvent and oil applications, classifications, types available, compositions and physical properties. Pesticidal efficacy effects and other technical considerations for choosing solvents and oils are also reviewed.
Beam shaping laser diode array output for optical pumping and illumination (2002)

The typical output divergence of a laser diode bar is about 40/spl deg//spl times/10/spl deg/ in the fast and slow axes, which can be difficult to optically couple into a rod or slab-shaped laser host. Depending on the distance from the laser host, a fast axis output of 7/spl deg/-10/spl deg/ may be acceptable. For side pumping a thin slab a fast axis output of 1/spl deg/ or less may be required to achieve the desired absorption profile. We have recently lensed 8, 25, and 30 bar stacks of laser diode bars, which were used to side pump Nd:YAG. Not only was the output divergence of each bar required to be lens than 1/spl deg/, but also the output of each bar was required to be parallel. In most cases optically polished anti-reflection coated cylindrical lenses are used to obtain brightness and uniformity.
In vitro comparison of cytochrome P450-mediated metabolic activities in human, dog, cat, and horse. (1997)

As domestic animals such as cat, horse, and dog increasingly become the clinical targets for drug discovery programs, the need to understand how these animals metabolize xenobiotics becomes more important. In the present study, substrates and inhibitors that were reported to be selective for particular P450 isozymes were used as probes to study in vitro metabolism in horse, dog, cat, and human liver microsomes. Seven selective catalytic activity markers for cytochrome P450-mediated reactions were measured: phenacetin O-deethylase (P4501A1/2), coumarin 7-hydroxylase (P4502A6), tolbutamide hydroxylase (P4502C8/9), S-mephenytoin 4'-hydroxylase (P4502C19), dextromethorphan O-demethylase (P4502D6), chlorzoxazone 6-hydroxylase (P4502E1), and testosterone 6beta-hydroxylase (P4503A4). Metabolic activity was found in every species with each substrate. Under the conditions of this study, it was observed that no one species was more active for any given substrate. However, rather large interspecies differences were observed. There was no marked sex difference in the way the various species metabolized the different substrates. The effect of selective P450 inhibitors on the various activities was tested with furafylline (P4501A2), mouse monoclonal antibody inhibitory to CYP2A6, sulfaphenazole (P4502C9), tranylcypromine (P4502C19), quinidine (P4502D6), diethyldithiocarbamate (P4502E1), and troleandomycin (P4503A4). In most cases, these inhibitors were effective to varying degrees against the activity seen in horse, dog, and cat liver microsomes. However, even at high concentrations, furafylline did not inhibit phenacetin O-deethylase activity in cat and troleandomycin did not affect testosterone 6beta-hydroxylase activity in horse. Sulfaphenazole was not tested in dog and cat because of the low tolbutamide hydroxylase activity. Overall, these results show that there are also large interspecies differences in the way the selective P450 inhibitors affect the in vitro metabolism of the various substrates in horse, dog, and cat liver microsomes.
Rats produced by interspecies spermatogonial transplantation in mice and<i>in vitro</i>microinsemination (2006)

Spermatogonial transplantation has demonstrated a unique opportunity for studying spermatogenesis and provided an assay for spermatogonial stem cells. However, it has remained unknown whether germ cells that matured in a xenogeneic environment are functionally normal. In this investigation, we demonstrate the successful production of xenogeneic offspring by using spermatogonial transplantation. Rat spermatogonial stem cells were collected from immature testis and transplanted into the seminiferous tubules of busulfan-treated nude mouse testis. Using rat spermatids or spermatozoa that developed in xenogeneic surrogate mice, rat offspring were born from fresh and cryopreserved donor cells after microinsemination with rat oocytes. These offspring were fertile and had a normal imprinting pattern. The xenogeneic offspring production by interspecies germ cell transplantation and in vitro microinsemination will become a powerful tool in animal transgenesis and species conservation.

Standardization of a newly designed vibrating capillary apparatus for the preparation of microcapsules (1993)

Abstract Vibrating capillary apparatus (VCA) was designed and constructed for the preparation of sulphamethoxazole (SMZ) microcapsules using gelatin as a coating polymer. The microcapsules were characterized by physico‐chemical methods. The apparent diffusion coefficient D a and diffusion rate constant K BL of the drug were measured at pH of 1.2 and 7.2. Better controlled release products were obtained in the VCA.
Welcome to the Neighborhood: Does Where you Live Affect the Use of Nutrition, Health, and Welfare Programs? (2009)

Despite the recent upsurge in neighborhood effects research, few studies have examined the impact of neighborhood characteristics on the use of nutrition, health, and welfare programs. To explore these issues, this study used data from Welfare, Children, and Families: A Three-City Study, a longitudinal dataset comprised of low-income neighborhoods in Boston, San Antonio, and Chicago (n=1,712). Using hierarchical linear models, the results indicated that both individual (education, employment, and marriage) and perceived neighborhood disorder factors were related to social service use.
The Pleasures and Pitfalls of Bibliography: A Personal Reminiscence (1980)

The start is way back-or rather, even before that, while I was still an undergraduate at Oxford.Three men introduced me to bibliography and stirred my imagination for what many find a dry field.Two of the three were nearing the end of their long careers and the third, just retiring at the age of sixty-one, also seemed old viewed by the young and easily awed.By a coincidence two of them were running, or had run, the Clarendon Press in Oxford; all three were "Press authors."Kenneth Sisam, in his last months as secretary (so called) to the Delegates of the Press, had employed me to do a vacation job on the addenda to the Little Oxford Dictionary; I had to explain that MCC stood for Marylebone Cricket Club and the like .Mr. Sisam'E
A frequency tripler with suppressed harmonics for millimeter-wave applications (2018)

A varactor based frequency tripler with suppressed first, second and fourth harmonics of the input signal is presented. Harmonic balance simulations show that the designed tripler delivers an output power of 13.6dBm for an input power of 26dBm at 42 GHz while the first and second harmonics are suppressed by more than 50 dB and the fourth harmonic by 17.5 dB with respect to the output signal at 42 GHz. A 75 pm quartz substrate and GaAs Schottkyvaractor diodes from Rutherford Appleton Laboratory have been used for the circuit design. A metal enclosure has been considered around the microstrip line circuit and the output signal is coupled to a rectangular waveguide using an E-plane probe transition from microstrip line.
Group Consistent Similarity Learning via Deep CRF for Person Re-identification (2018)

Person re-identification benefits greatly from deep neural networks (DNN) to learn accurate similarity metrics and robust feature embeddings. However, most of the current methods impose only local constraints for similarity learning. In this paper, we incorporate constraints on large image groups by combining the CRF with deep neural networks. The proposed method aims to learn the "local similarity" metrics for image pairs while taking into account the dependencies from all the images in a group, forming "group similarities". Our method involves multiple images to model the relationships among the local and global similarities in a unified CRF during training, while combines multi-scale local similarities as the predicted similarity in testing. We adopt an approximate inference scheme for estimating the group similarity, enabling end-to-end training. Extensive experiments demonstrate the effectiveness of our model that combines DNN and CRF for learning robust multi-scale local similarities. The overall results outperform those by state-of-the-arts with considerable margins on three widely-used benchmarks.
An improved power MOSFET using a novel split well structure (2003)

The design trade-offs between the specific on-resistance (R/sub sp/), the ruggedness and the reverse recovery charge (Q/sub rr/) of the body-diode for vertical power MOSFETs has been significantly improved by using a novel split-well (SW) concept. The implementation of the SW structure is straightforward with low cost. It is expected that the source exclusion mask can be removed. When compared to a conventional VDMOST with the same design rules, the SW device provides 15% lower R/sub sp/ and 10% lower Q/sub rr/ without degradation of device ruggedness. In addition, it is expected that the SW device will yield higher hot-carrier reliability.

Influence of the nigrosine dye on the thermal behavior of polyamide 66 (2006)

Abstract To reveal the effect of the nigrosine dye, that the addition of the dye lowers the crystallization point ( T c ) of molten polyamide resins with substantially no shift in the melting point ( T m ), thus suppressing the crystallization enhancement of the crystalline nucleation agents, the characteristics of polyamide 66 (PA‐66) containing nigrosine dye EX (N‐EX) were investigated. Differential scanning calorimetry (DSC) analysis showed that the addition of N‐EX reduced the crystallization rate and T c of molten PA‐66 with substantially no shift in T m , and the crystallization enthalpy per unit of weight of PA‐66 was substantially constant. T c of molten PA‐66 was lowered with an increase in the amount of N‐EX and reached its maximum at 13 wt % N‐EX. Dynamic mechanical analysis showed that the glass‐transition temperature and the secondary glass‐transition temperature increased with an increasing amount of the dye. On the other hand, the DSC and X‐ray diffraction results indicated that no dye molecule was present in the crystal structure of PA‐66. This effect of the nigrosine dye on PA‐66 is in contrast to those of crystalline nucleation agents, plasticizers, and antiplasticizers. © 2006 Wiley Periodicals, Inc.

An efficient stereospecific synthesis of these compounds and a series of structural analogues is described. Compounds 31 and 37 both inhibited the bronchoconstriction induced by arachidonic acid in the anesthetized guinea pig.
System-level requirements of DC-DC converters for dynamic power supplies of power amplifiers (2003)

The energy efficiency of battery-operated portable applications can be improved by increasing the efficiency of power amplifiers (PAs). By dynamically changing the supply voltage from the fixed battery supply using a DC-DC converter, the PA can be operated with high efficiency during power back-off. This paper presents the system level requirements for a buck converter and other blocks in a dynamic power supply scheme for PA. Simulation results for the effects of ripple in the power supply of the PA and delay mismatch using behavioral models of constituent blocks and circuit-level PA have been presented.
Multi-cell soft errors at the 16-nm FinFET technology node (2015)

Soft error performance of 16-nm FinFET SRAM designs fabricated using a commercial bulk CMOS process is evaluated using heavy-ions. Results included supply voltage variations show that multi-cell upsets dominate soft-error rates. Dual-port SRAM has higher cross-section than single-port SRAM but did not have any multi-cell upset across the bit-line direction. TCAD simulations showing the extent of the perturbation in the electric parameters as a function of particle LET support the experimental data.
