Ontology-based approach for standard formats integration in reservoir modeling (2015)

A integração de dados oriundos de fontes autônomas e heterogêneas ainda é um grande problema para diversas aplicações. Na indústria de petróleo e gás, uma grande quantidade de dados é gerada diariamente a partir de múltiplas fontes, tais como dados sísmicos, dados de poços, dados de perfuração, dados de transporte e dados de marketing. No entanto, estes dados são adquiridos através da aplicação de diferentes técnicas e representados em diferentes formatos e padrões. Assim, estes dados existem de formas estruturadas em banco de dados e de formas semi-estruturadas em planilhas e documentos, tais como relatórios e coleções multimídia. Para lidar com a heterogeneidade dos formatos de dados, a informação precisa ser padronizada e integrada em todos os sistemas, disciplinas e fronteiras organizacionais. Como resultado, este processo de integração permitirá uma melhor tomada de decisão dentro de colaborações, uma vez que dados de alta qualidade poderão ser acessados em tempo hábil. A indústria do petróleo depende do uso eficiente desses dados para a construção de modelos computacionais, a fim de simplificar a realidade geológica e para ajudar a compreende-la. Tal modelo, que contém objetos geológicos analisados por diferentes profissionais—geólogos, geofísicos e engenheiros — não representa a realidade propriamente dita, mas a conceitualização do especialista. Como resultado, os objetos geológicos modelados assumem representações semânticas distintas e complementares no apoio à tomada de decisões. Para manter os significados pretendidos originalmente, ontologias estão sendo usadas para explicitar a semântica dos modelos e para integrar os dados e arquivos gerados nas etapas da cadeia de exploração. A principal reivindicação deste trabalho é que a interoperabilidade entre modelos da terra construídos e manipulados por diferentes profissionais e sistemas pode ser alcançada evidenciando o significado dos objetos geológicos representados nos modelos. Nós mostramos que ontologias de domínio desenvolvidas com o apoio de conceitos teórico de ontologias de fundamentação demonstraram ser uma ferramenta adequada para esclarecer a semântica dos conceitos geológicos. Nós exemplificamos essa capacidade através da análise dos formatos de comunicação padrões mais utilizados na cadeia de modelagem (LAS, WITSML e RESQML), em busca de entidades semanticamente relacionadas com os conceitos geológicos descritos em ontologias de Geociências. Mostramos como as noções de identidade, rigidez, essencialidade e unidade, aplicadas a conceitos ontológicos, conduzem o modelador à definir mais precisamente os objetos geológicos no modelo. Ao tornar explícitas as propriedades de identidade dos objetos modelados, o modelador pode superar as ambiguidades da terminologia geológica. Ao fazer isso, explicitamos os objetos e propriedades relevantes que podem ser mapeados a partir de um modelo para outro, mesmo quando eles estão representados em diferentes nomes e formatos.
Immunological Studies of Y Protein. A MAJOR CYTOPLASMIC ORGANIC ANION-BINDING PROTEIN IN RAT LIVER (1972)

An antibody produced against rat Y protein, the major cytoplasmic organic anion-binding protein in liver, was characterized. The antibody precipitated Y protein from liver supernatant fractions and specifically removed the organic anion-binding capacity from this fraction.Y protein was detected by immunodiffusion with this antibody in the supernates of rat liver, kidney, and small intestinal mucosa and was not detected in supernates of 16 other tissues including bile and serum. Precipitation with anti-Y was not detected with supernates of liver from 20 other species, including man. Quantitative radial immunodiffusion revealed Y protein to constitute 4.5% of supernatant protein in rat liver and approximately 2% of supernatant protein in rat kidney and small intestinal mucosa. Phenobarbital administration increased the concentration of Y protein in rat liver by 280%, but not in kidney or small intestinal mucosa, and was associated with increased plasma disappearance of sulfobromphthalein sodium, indocyanine green, and bilirubin, and increased hepatic, but not kidney or small intestinal mucosal, content of these organic anions. These observations provide further evidence indicating that the concentration of Y protein is a major determinant of organic anion flux across the plasma membrane of the liver cell.Immunodiffusion and immunoelectrophoresis revealed serological identity between Y protein, cortisol metabolite-binding protein I. and the major azocarcinogen-binding protein.

Rapid Defrost Transparent Thin-Film Heater with Flexibility and Chemical Stability (2020)

Zn-doped SnO<sub><i>x</i></sub>/Ag/Zn-doped SnO<sub><i>x</i></sub>(ZTO/Ag/ZTO) multilayer thin films fabricated on a polyethylene terephthalate (PET) substrate using an optimized N<sub>2</sub>-to-(Ar + O<sub>2</sub>) gas ratio are used for transparent thin-film heaters with high performance and chemical stability. The ZTO/Ag/ZTO-based multilayer thin film exhibits enhanced durability at high temperatures and humid environments by incorporating nitrogen. The bending test results-there was no significant change in the sheet resistance even after 10,000 bending cycles-highlight the mechanical flexibility of the ZTO/Ag/ZTO multilayer thin film. The ZTO/Ag/ZTO-based thin-film heater on PET, fabricated under optimized deposition gas conditions, exhibits a fast thermal response time of 30 s and a low driving voltage of 6 V to attain 100 °C. It also exhibits uniform heat distribution at saturated temperature and chemical stability after 100 heating-cooling cycles. Hence, the proposed ZTO/Ag/ZTO-based thin-film heater is applicable for use in front and rear window automobile and building applications.

Purification of Pharmaceutical Excipients with Supercritical Fluid Extraction (2005)

Supercritical fluid extraction (SFE), with carbon dioxide as the solvent, was tested for its ability to remove common reactive impurities from several pharmaceutical excipient powders including starch, microcrystalline cellulose (MCC), hydroxypropylcellulose (HPC), polyethylene oxide (PEO), and polyvinylpyrrolidone (PVP). Extraction of the small molecule impurities, formic acid and formaldehyde, was conducted using SFE methods under conditions that did not result in visible physical changes to polymeric excipient powders. It could be shown that spiked, largely surface-bound, impurities could be removed effectively; however, SFE could only remove embedded impurities in the excipient particles after significant exposure times due to slow diffusion of the impurities to the particle surfaces. Attempts at hydrogen peroxide extraction were hindered by its low solubility in CO2, thereby effectively precluding SFE for removal of hydrogen peroxide from excipients. This work suggests that SFE will only be commercially useful for removal of low molecular weight impurities in polymeric excipients when migration of the impurities to the particle surfaces is sufficiently rapid for extraction to be completed in a reasonable time frame.
The Conserved Immunoglobulin Domain Controls the Subcellular Localization of the Homophilic Adhesion Receptor Protein-tyrosine Phosphatase μ (2004)

The receptor protein-tyrosine phosphatase mu (PTPmu) is a homophilic adhesion protein thought to regulate cell-cell adhesion in the vascular endothelium through dephosphorylation of cell junction proteins. In subconfluent cell cultures, PTPmu resides in an intracellular membrane pool; however, as culture density increases and cell contacts form, the phosphatase localizes to sites of cell-cell contact, and its expression level increases. These characteristics of PTPmu, which are consistent with a role in cell-cell adhesion, suggest that control of subcellular localization is an important mechanism to regulate the function of this phosphatase. To gain a better understanding of how PTPmu is regulated, we examined the importance of the conserved immunoglobulin domain, containing the homophilic binding site, in control of the localization of the enzyme. Deletion of the immunoglobulin domain impaired localization of PTPmu to the cell-cell contacts in endothelial and epithelial cells. In addition, deletion of the immunoglobulin domain affected the distribution of PTPmu in subconfluent endothelial cells when homophilic binding to another PTPmu molecule on an apposing cell was not possible, resulting in an accumulation of the mutant phosphatase at the cell surface with a concentration at the cell periphery in the region occupied by focal adhesions. This aberrant localization correlated with reduced survival and alterations in normal focal adhesion and cytoskeleton morphology. This study therefore illustrates the critical role of the immunoglobulin domain in regulation of the localization of PTPmu and the importance of such control for the maintenance of normal cell physiology.
Location Estimation via Support Vector Regression (2007)

Location estimation using the Global System for Mobile communication (GSM) is an emerging application that infers the location of the mobile receiver from multiple signals measurements. While geometrical and signal propagation models have been deployed to tackle this estimation problem, the terrain factors and power fluctuations have confined the accuracy of such estimation. Using support vector regression, we investigate the missing value location estimation problem by providing theoretical and empirical analysis on existing and novel kernels. A novel synthetic experiment is designed to compare the performances of different location estimation approaches. The proposed support vector regression approach shows promising performances, especially in terrains with local variations in environmental factors.
Type I Receptors Specify Growth-Inhibitory and Transcriptional Responses to Transforming Growth Factor β and Activin (1994)

Transforming growth factor beta (TGF-beta) and activin bind to receptor complexes that contain two distantly related transmembrane serine/threonine kinases known as receptor types I and II. The type II receptors determine ligand binding specificity, and each interacts with a distinct repertoire of type I receptors. Here we identify a new type I receptor for activin, ActR-IB, whose kinase domain is nearly identical to that of the recently cloned TGF-beta type I receptor, T beta R-I. ActR-IB has the structural and binding properties of a type I receptor: it binds activin only in the presence of an activin type II receptor and forms a heteromeric noncovalent complex with activin type II receptors. In Mv1Lu lung epithelial cells, ActR-IB and T beta R-I signal a common set of growth-inhibitory and transcriptional responses in association with their corresponding ligands and type II receptors. The transcriptional responses include elevated expression of fibronectin and plasminogen activator inhibitor 1. Although T beta R-I and ActR-IB are nearly identical in their kinase domains (90% amino acid sequence identity), their corresponding type II receptor kinase domains are very different from each other (42% amino acid sequence identity). Therefore, signaling of a specific set of responses by TGF-beta and activin correlates with the presence of similar type I kinases in their complex. Indeed, other TGF-beta and activin type I receptors (TSR-I and ActR-I) whose kinase domains significantly diverge from those of T beta R-I and ActR-IB do not substitute as mediators of these growth-inhibitory and extracellular matrix transcriptional responses. Hence, we conclude that the type I receptor subunits are primary specifiers of signals sent by TGF-beta and activin receptor complexes.
The hybrid SAR-ISAR imaging algorithm applied to SAR moving target imaging (2012)

Typical SAR imaging aims at the static targets, which means that target is static and radar is moving. By contrast, ISAR imaging aims at the moving targets, which means that target is moving and radar is static. When detecting the moving targets by SAR, both radar and target are moving, which shows that rhe echo of moving targets not only have the component of SAR but also that of ISAR. Generally speaking, imaging of SAR moving target usually adopts the R-D algorithm of typical SAR. But the method which combines SAR imaging technique with ISAR imaging technique, is more reasonable. Therefore, on the basis of parameter estimations, a kind of hybrid SAR-ISAR imaging algorithm, which applied to moving target imaging, is presented. The simulation results validate the effectiveness of this algorithm.
A Comparison of Prognosis between Patients with Hepatitis B and C Virus‐related Hepatocellular Carcinoma Undergoing Resection Surgery (2011)

Viral etiologies were not apparent in determining outcomes of HCC patients who underwent resection due to heterogeneous studied populations. In early-stage HCC, B-HCC patients had better outcomes than C-HCC patients did because of better liver reserve and less hepatic inflammation.
Self-assembled Ge dots: Growth, characterization, ordering, and applications (1998)

The Stranski–Krastanow growth mode, which leads to the self-assembled formation of dots, allows one to exceed the critical thickness without introducing dislocations. We report the coverage limits for the dislocation-free dot regime in dependence of the Ge content, and also the composition dependent thickness of the two-dimensional wetting layer. To reduce the size inhomogeneity of the self-assembled dots, we investigated ordering effects in Si/Ge-dot multilayers. The experiments do not only reveal a strong vertical ordering of the dots, but also a lateral correlation and a significantly increased size homogeneity is observed. Results on first device structures, a npn-infrared detector and a silicon based tunneling structure, both with embedded layers of self-assembled Ge dots, are presented.

An ALBERT-based Similarity Measure for Mathematical Answer Retrieval (2021)

Mathematical Language Processing (MLP) deals with the automated processing and analysis of mathematical documents and relies heavily on good representations of mathematical symbols and texts. The aim of this work is to explore the modeling capabilities of state-of-the-art unsupervised deep learning methods to create such representations. Therefore, we pre-trained different instances of an ALBERT model on Mathematics StackExchange data and fine-tuned it on the task of Mathematical Answer Retrieval. Our evaluation shows that ALBERT outperforms all previous systems and is on par with current state-of-the-art systems for math retrieval indicating strong capabilities of modeling mathematical posts. This implies that our approach can also be beneficial to various other tasks in MLP such as automatic proof checking or summarization of scientific texts.
Quick Preparation of Moisture-Saturated Carbon Fiber-Reinforced Plastics and Their Accelerated Ageing Tests Using Heat and Moisture (2016)

A quick method involving the control of heat and water vapor pressure for preparing moisture-saturated carbon fiber-reinforced plastics (CFRP, 8 unidirectional prepreg layers, 1.5 mm thickness, epoxy resin) has been developed. The moisture-saturated CFRP sample was obtained at 120 °C and 0.2 MPa water vapor in 72 h by this method using a sterilizer (autoclave). The bending strength and viscoelastic properties measured by a dynamic mechanical analysis (DMA) remained unchanged during repetitive saturation and drying steps. No degradation and molecular structural change occurred. Furthermore an accelerated ageing test with two ageing factors, <i>i.e.</i>, heat and moisture was developed and performed at 140⁻160 °C and 0.36⁻0.62 MPa water vapor pressure by using a sealed pressure-proof stainless steel vessel (autoclave). The bending strength of the sample decreased from 1107 to 319 MPa at 160 °C and 0.63 MPa water vapor pressure in 9 days. Degraded samples were analyzed by DMA. The degree of degradation for samples was analyzed by DMA. CFRP and degraded CFRP samples were analyzed by using a surface and interfacial cutting analysis system (SAICAS) and an electron probe micro-analyzer (EPMA) equipped in a scanning electron microscope.
Millimeter-wave wireless communication in a data center cabinet with adaptive control of propagation (2015)

A 60 GHz wireless communication system has been proposed as a replacement for data cables in a data-center cabinet in order to reduce the significant cooling energy costs. This paper investigates the feasibility of placing adaptive absorber-reflector regions on the sides of a cabinet as a static channel fading counter-measure and also to optimize performance for a particular server. As a result of a ray-tracing simulation it is shown that the capacity could be increased by 2.8 bits/s/Hz at an SNR of 20 dB at the median value.

Design and Synthesis of Phosphorescent Iridium Containing Dendrimers for Potential Applications in Organic Light‐Emitting Diodes (2008)

Abstract Three phosphorescent dendrimers ( IrC1 , IrC3 , and IrF2 ) with an iridium complex core and oligocarbazole or oligofluorene substituted ligands were synthesized and characterized. The structures of the oligocarbazole were designed to maintain high triplet energy of the ligands so that phosphorescence quenching in the resulting dendrimers can be prevented, while the oligofluorene in IrF2 resulted in undesired phosphorescence quenching. Best performance was obtained from an IrC3 based electrophosphorescent light‐emitting device with a maximum luminance of 13 060 cd · m −2 at a driving voltage of 11.5 V and a peak current‐efficiency of 4.3 cd · A −1 at a luminance of 3 400 cd · m −2 , owing to its high PL efficiency, and efficient energy transfer between the iridium complex core and the ligands. magnified image
Non-line-of-sight underwater optical wireless communication network (2009)

The growing need for ocean observation systems has stimulated considerable interest within the research community in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. Sensors and ad hoc sensor networks are the emerging tools for performing extensive data-gathering operations on land, and solutions in the subsea setting are being sought. Efficient communication from the sensors and within the network is critical, but the underwater environment is extremely challenging. Addressing the special features of underwater wireless communication in sensor networks, we propose a novel non-line-of-sight network concept in which the link is implemented by means of back-reflection of the propagating optic signal at the ocean-air interface and derive a mathematical model of the channel. Point-to-multipoint links can be achieved in an energy efficient manner and broadcast broadband communications, such as video transmissions, can be executed. We show achievable bit error rates as a function of sensor node separation and demonstrate the feasibility of this concept using state-of-the-art silicon photomultiplier detectors.
Synthesis and Investigation of [Cp*(PMe3)Rh(H)(H2)]+ and Its Partially Deuterated and Tritiated Isotopomers:  Evidence for a Hydride/Dihydrogen Structure (2002)

Hydrogenolysis of [Cp(PMe(3))Rh(Me)(CH(2)Cl(2))](+)BAr'(4)(-) (4, Ar' = 3,5-C(6)H(3)(CF(3))(2)) in dichloromethane afforded the nonclassical polyhydride complex [Cp*PMe(3))Rh(H)(H(2))](+)BAr'(4)(-) (1), which exhibits a single hydride resonance at all accessible temperatures in the (1)H NMR spectrum. Exposure of solutions of 1 to D(2) or T(2) gas resulted in partial isotopic substitution in the hydride sites. Formulation of 1 as a hydride/dihydrogen complex was based upon T(1) (T(1)(min) = 23 ms at 150 K, 500 MHz), J(H-D) (ca. 10 Hz), and J(H-T) (ca. 70 Hz) measurements. The barrier (Delta G(++)) to exchange of hydride with dihydrogen sites was determined to be less than ca. 5 kcal/mol. Protonation of Cp(PMe(3))Rh(H)(2) (2) using H(OEt(2))(2)BAr'(4) resulted in binuclear species [(Cp(PMe(3))Rh(H))(2)(mu-H)](+)BAr'(4)(-) (3), which is formed in a reaction involving 1 as an intermediate. Complex 3 contains two terminal hydrides and one bridging hydride ligand which exchange with a barrier of 9.1 kcal/mol as observed by (1)H NMR spectroscopy. Additionally, the structures of 3 and 4, determined by X-ray diffraction, are reported.
