Gas Blowdown Case Study: Striking a Fine Balance in Maximizing Gas Production Plateau and Minimizing Oil Loss: A Case Study of a Gas Blowdown Development Plan for a Mature Clastic Field in Oman (2010)

Abstract PDO is a major operator in the Middle East with long production history for many of its oil fields. Due to the increased gas supply requirements, it is considering options for blowing down the gas caps of some selected oil fields to cater for the gas demand for achieving sustainable oil production. The key challenge for these gas blow down is to maximize gas production plateau while simultaneously minimise associated oil recovery losses. This Case Study illustrates the Gas Blowdown optimisation of a saturated clastic oil reservoir. During the Blowdown Study, optimum gas production rates from each of the Upper and Middle Gharif reservoirs are targeted to meet a given gas production plateau rate. A fit-for-purpose assessment for the impact of subsurface parameter uncertainties on the proposed development demonstrated robustness of the gas production plateau period. This analysis resulted in a Gas production Plateau period ranging from 4 years (Low case) to 7 years (High case) with an expectation case of 6 years. Multiple Subsurface &amp; Surface development scenarios have been evaluated including lowering pressure ratings for the Separator inlet pressure. The oil &amp; gas production profiles thus generated have been evaluated for robust economics and used for final concept selection &amp; field implementation. Furthermore to minimise oil losses various optimisation efforts have been identified during pre and post blow down phases in terms of re-perforations, gas lift implementation and blow down oriented well and reservoir management practices. This case study proposes an optimised Gas Blowdown field development by maximizing gas plateau period while minimizing associated oil loss. The Study resulted in selecting the appropriate surface development concept, operating specifications and provided an optimised field management plan during the Blowdown phase. The methodology adopted in this case study should find wider applicability in the industry.
Effect of antimacrophage serum on the proliferation of glomerular cells in nephrotoxic serum nephritis in the rat. (1989)

To evaluate the effect of a rabbit anti-rat macrophage serum (AMS) on glomerular cells in vivo, glomeruli were isolated from an accelerated autologous form of nephrotoxic serum nephritis (NTSN) in rats and grown in tissue culture. The prominent feature of the glomerular outgrowth of the glomeruli in the NTSN was the presence of large numbers of type III (macrophages) cells, which were not present in cultured normal glomeruli. In addition, there were significantly greater numbers of type II (mesangial) cells in culture from the NTSN rats as compared with glomeruli from normal rats though the numbers of type I (epithelial) cells were the same. The administration of AMS prevented the outgrowth of macrophages and reduced the number of mesangial cells in the outgrowth of glomeruli from the NTSN rats. The AMS-treated rats showed profound reduction in proteinuria. Light micrographs showed only minor histologic lesion in the AMS-treated rats. These findings suggest that AMS may be applicable to the modulation of the proliferative response seen in NTSN.

Non‐Hodgkin lymphoma in Romania: a single‐centre experience (2015)

Epidemiologic studies of non-Hodgkin lymphoma (NHL) in Eastern Europe are scarce in the literature. We report the experience of the "Ion Chiricuta" Institute of Oncology in Cluj-Napoca (IOCN), Romania, in the diagnosis and outcome of patients with NHL. We studied 184 consecutive NHL patients diagnosed in the Pathology Department of IOCN during the years 2004-2006. We also obtained epidemiological data from the Northwestern (NW) Cancer Registry. In the IOCN series, the most common lymphoma subtype was diffuse large B-cell lymphoma (43.5%), followed by the chronic lymphocytic leukaemia/small lymphocytic lymphoma (21.2%). T-cell lymphomas represented a small proportion (8.2%). The median age of the patients was 57 years, with a male-to-female ratio of 0.94. Patients with indolent B-cell lymphomas had the best overall survival, whereas those with mantle cell lymphoma had the worst survival. The NW Cancer Registry data showed that the occurrence of NHL in the NW region of Romania was higher in men [world age-standardized incidence rate/100 000 (ASR)-5.9; 95% CI 5.1-6.6] than in women (ASR-4.1; 95% CI 3.5-4.7) with age-standardized male-to-female ratio of 1.44 (p = 0.038). Chronic lymphocytic leukaemia/small lymphocytic lymphoma was the most common NHL in the NW region of Romania, accounting for 43% of all cases, followed by diffuse large B-cell lymphoma (36%). The 5-year, age-standardized cumulative relative survival for NHL in the County of Cluj in NW Romania, for the period of 2006-2010, was 51.4%, with 58.4% survival for men and 43.2% for women. Additional studies of NHL in Eastern Europe are needed. Copyright © 2015 John Wiley & Sons, Ltd.
Beam Purification by Photodetachment (2012)

Ion beam purity is of crucial importance to many basic and applied studies. Selective photodetachment has been proposed to suppress unwanted species in negative ion beams while preserving the intensity of the species of interest. A highly efficient technique based on photodetachment in a gas-filled radio frequency quadrupole ion cooler has been demonstrated. In off-line experiments with stable ions, up to 104 times suppression of the isobar contaminants in a number of interesting radioactive negative ion beams has been demonstrated. For selected species, this technique promises experimental possibilities in studies on exotic nuclei, accelerator mass spectrometry, and fundamental properties of negative atomic and molecular ions.
Multiplex serological assay for establishing serological profiles of polymorphic, closely related peptide antigens (2021)

Profiling of serological responses to establish the landscape of antibody specificities in individuals exposed to pathogens or vaccines is crucial for (a) revealing humoral immune correlates of protection; (b) uncovering markers of pathogen exposure; and (c) identifying antigens and epitopes associated with disease <i>vs.</i> protection. Establishing the antigenic profile of serological responses requires either expensive microarrays or labor- and time-intensive ELISA assays. Multiplex assay platforms are increasingly being evaluated for their usefulness for high-throughput testing of sera or plasma. The methodology described here utilizes a plate-based assay that allows the simultaneous detection of up to ten antigens per well in a 96 well format using an electrochemiluminescence immunoassay (ECLIA).•The newly developed protocol outlines high-throughput profiling of serological responses using a multiplex testing platform with subsequent computational analysis.•The protocol is a modification of the basic assay development manual from the manufacturer of the MESO QuickPlex SQ 120 instrument (MSD, Gaithersburg, MD) and can be used for synthetic peptides as well as full length proteins.•The protocol can be applied to map serological responses to pathogens or pathogen-derived antigens to establish serological profiles in search for biomarkers or immune correlates.

Packaging of a BiCMOS Sensor on a catheter tip for the characterisation of atherosclerotic plaque (2016)

The paper deals with a new technique for deviation of atherosclerotic plaque. There are two plaque types: The yellow and white plaque. The white plaque is hard, fibrous and dimensionally stable. The yellow plaque is soft with high-cholesterol ratio and dimensionally instable. Every hit with a medical tool can generate a critical medical case, because the plaque can be rapture and the plaque particles could cause in a stroke. A catheter with a BiCMOS microwave sensor was developed in the latest research. For a stable function and a high reliability a suitable electronic packaging has to be fulfill. The development starting with the sensor design up to a complete electronic packaging which allows a measurement in different liquids and tissues is discussed in this paper.

TecDIY—Motivation methodology for the practical laboratories preparation and exams of electronics subject (2019)

Abstract This proposal is concerned with a new methodology named Tecnology and Electronics—Do It Yourself (TECDIY) with the aim to motivate students of the first course of systems and multimedia engineering grade to prepare the practical laboratories and the exams of Physics and Electronics subject. The methodology consists in integrating projects‐based learning (‐) and the motivation for the practical laboratories and exams using preprepared videos, models adaptation of the theory, exercises, and problems preparation Gymkana. In addition, TECDIY methodology is supported by an attendance registration system, which allows the students assistance to class to be verified and controlled. The study is performed by comparing indicators, namely the predelivery of the laboratories theoretic calculations, the problems delivery, and assistance to class, performed in three academic years (2013–2014, 2014–2015, and 2015–2016). The results of applying this method demonstrate a significant increase of these indicators, which means the efficiency of TECDIY method in motivating the students to prepare the exam and the practical laboratories.
Ultrasound‐Assisted Liquid‐Phase Synthesis and Mechanical Properties of Aluminum Matrix Nanocomposites Incorporating Boride Nanocrystals (2021)

Incorporating boride nanocrystals could significantly impact the mechanical properties of aluminum alloys. Molten salts synthesis offers opportunities to fabricate superhard boride nanoparticles, which can sustain the harsh conditions during the liquid-phase design of metallic nanocomposites. Here hafnium diboride-aluminum nanocomposites are unveiled from molten salt-derived HfB<sub>2</sub> nanoparticles sequentially dispersed in aluminum by ultrasound treatment. The structure and size of the nanocrystals are retained in the final nanocomposites, supporting their high chemical stability. Semicoherent interfaces between the nanoparticles and the matrix are then evidenced by TEM, suggesting that the nanocrystals could promote heterogeneous nucleation of Al and then limit the Al grain size to ≈20 µm. Nanoindentation measurements reveal significant grain boundary strengthening and grain refinement effects. It is finally shown that HfB<sub>2</sub> nanoparticles also enable a decrease in matrix grain size and an increase in the hardness of the AlSi<sub>7</sub> Cu<sub>0.5</sub> Mg<sub>0.3</sub> alloy. These proof-of-concept materials are paving the way to light-weight Al matrix nanocomposites doped by molten-salt synthesized nanoparticles.
<title>Performance of an iterative reconstruction algorithm for near-infrared absorption and scatter imaging</title> (1993)

We have developed an iterative reconstruction algorithm for TOAST, based on a finite element method (FEM) forward model that is fast and very flexible. The algorithm can be used at present with either non-time-resolved and/or time-resolved data, and can reconstruct either (mu) <SUB>a</SUB> and/or (mu) <SUB>s</SUB> parameters. An equivalent version can be formulated in terms of phase shift and modulation frequency. The basis of the algorithm is to attempt to find the minimum error norm between the measured data and the forward model acting on the trial solution, by a `classical' non-linear search in the distribution of the (mu) <SUB>a</SUB> and (mu) <SUB>s</SUB> parameters. In principle any search strategy could be used, but the advantage of our approach is that it employs analytical results for the gradient change (partial)M/(partial)(mu) , where M is the measurement. A number of factors influence the performance of the algorithm -- sampling density of the data and solution, noise in the data, accuracy of the model, and appropriate usage of a priori information. It appears that the presence of local minima of the error norm surface cannot be ignored. This paper presents an analysis of the performance of the algorithm on data generated from the FEM model, and from an independent Monte-Carlo model.
Impact of 12 months of androgen-deprivation therapy (ADT) on cognitive function in men with nonmetastatic prostate cancer (PC): A matched cohort study. (2010)

9027 Background: ADT is used to treat almost 50% of current PC patients. Despite slowing disease progression and prolonging survival, ADT is associated with numerous side effects. However, the impact of ADT on cognitive function remains uncertain, limited by small published studies and inconsistent findings. Methods: Men age 50 or older with non-metastatic prostate cancer (PC) were included. Three separate groups matched on age and education were tested longitudinally for cognitive function; PC patients starting continuous ADT (n = 79), PC patients not receiving ADT (PC controls, n = 83), and healthy controls (n = 82). A battery of 12 neuropsychological tests, examining 8 cognitive domains, was administered at baseline (prior to ADT treatment), 6 months, and 12 months later. Mean scores at baseline were compared using ANCOVA, and change scores between baseline and both 6 months and 12 months were analyzed using multivariable linear regression models. In an alternate analysis, the proportion of subjects per group with 1-SD or greater cognitive changes were compared. Results: The mean age and education level of the patients overall was 69.2 years (range 50-87) and 15.4 years (range 8-24), respectively. All 3 cohorts had similar adjusted cognitive scores at baseline other than in 1 test of working memory. Adjusted for age and education, ADT use was not associated with significant changes in the domains of Attention and Processing Speed, Verbal Fluency, Verbal Memory, Visual Memory, or Executive Functions of Cognitive Flexibility from baseline to either 6 months (all p<0.05) or 12 months (all p<0.05). 1 test of Immediate Memory (p = 0.033), 1 test of Working Memory (p = 0.037), and 1 test of Visuo-Spatial Ability (p = 0.029) were worse among ADT users than controls at 12 months, but these findings were not confirmed by other domain-specific cognitive tests or in analyses of 1-SD change per group. Conclusions: In the largest study to date, there is no consistent evidence of decline in cognitive function with ADT use for 12 months across 8 cognitive domains compared with controls. No significant financial relationships to disclose.
Synthesis of robust delay-fault-testable circuits: practice (1992)

The authors show how an orchestration of combinational synthesis for testability approaches can result in logic-level implementations of large integrated circuit designs that are completely robustly gate-delay-fault and path-delay-fault testable. For control portions of VLSI circuits, Boolean covering and algebraic factorization procedures that guarantee path-delay-fault testability are used, starting from a sum-of-products representation of a function. Hierarchical composition rules are used in the synthesis of regular structures occurring in data path portions, such as parity generators and arithmetic units. It is shown how test vectors to detect all path delay faults can be obtained as a by-product of the synthesis process. These techniques were used on circuits with over 5000 gates, and preliminary experimental results on a data encryption chip, a small microprocessor, and a speech recognition chip are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A nanometre-scale resolution interference-based probe of interfacial phenomena between microscopic objects and surfaces (2013)

Interferometric techniques have proven useful to infer proximity and local surface profiles of microscopic objects near surfaces. But a critical trade-off emerges between accuracy and mathematical complexity when these methods are applied outside the vicinity of closest approach. Here we introduce a significant advancement that enables reflection interference contrast microscopy to provide nearly instantaneous reconstruction of an arbitrary convex object's contour next to a bounding surface with nanometre resolution, making it possible to interrogate microparticle/surface interaction phenomena at radii of curvature 1,000 times smaller than those accessible by the conventional surface force apparatus. The unique view-from-below perspective of reflection interference contrast microscopy also reveals previously unseen deformations and allows the first direct observation of femtolitre-scale capillary condensation dynamics underneath micron-sized particles. Our implementation of reflection interference contrast microscopy provides a generally applicable nanometre-scale resolution tool that can be potentially exploited to dynamically probe ensembles of objects near surfaces so that statistical/probabilistic behaviour can be realistically captured.
Technological design considerations for monolithic MOS switched-capacitor filtering systems (1983)

In this paper, various technological and topological considerations for the design of monolithic MOS switched-capacitor (SC) filtering systems are described. The properties of the passive and active devices typically available in depletion-load NMOS and CMOS technologies are presented as they relate to various SC peformance parameters. Layout techniques for improving specific performance parameters are also given. An overview of MOS operational-amplifier design emphasizes technological considerations in the design of high-performance SC systems. Finally, several important techniques are reviewed for maximizing dynamic range in SC circuits.
Spectral Degeneracy Breaking of the Plasmon Resonance of Single Metal Nanoparticles by Nanoscale Near-Field Photopolymerization (2007)

We report on controlled nanoscale photopolymerization triggered by enhanced near fields of silver nanoparticles excited close to their dipolar plasmon resonance. By anisotropic polymerization, symmetry of the refractive index of the surrounding medium was broken: C infinity v symmetry turned to C2v symmetry. This allowed for spectral degeneracy breaking in particles plasmon resonance whose apparent peak became continuously tunable with the incident polarization. From the spectral peak, we deduced the refractive-index ellipsoid fabricated around the particles. In addition to this control of optical properties of metal nanoparticles, this method opens new routes for nanoscale photochemistry and provides a new way of quantification of the magnitude of near fields of localized surface plasmons.
CSS Layout Engine for Compound Documents (2006)

XML is nowadays widely used to describe structural documents on the WWW. The layout of the documents can be defined by style sheets or by a language itself. XML languages can be combined to get the desired set of features for a document. Those documents are called compound documents. Also, multimedia applications can be defined using XML. In this paper, we have defined general requirements for a compound documents' CSS layout engine, which can be used in an XML user agent. The requirements relate to features of the layout engine, devices in which it can operate, and interfaces of the cooperating components. In addition, we describe our own implementation of a layout engine, which is done according to the requirements and operates in different devices.
Different effects of sodium or chloride depletion on angiotensin II receptors in rats (1990)

We studied the effects of selective chronic sodium or chloride depletion (0.005% in diet) on central and peripheral angiotensin II receptors in young rats. Chloride depletion produced the most significant increase in plasma renin activity and extracellular fluid volume contraction. In the brain, subfornical organ angiotensin II receptor concentration was decreased by sodium depletion and increased by chloride depletion. There were no significant changes in angiotensin II binding in the paraventricular nucleus. When sodium-depleted rats were water deprived for 3 days, subfornical organ angiotensin II receptor concentration increased, showing that normal sodium intake was not essential for increased numbers of angiotensin II receptors during dehydration. In the adrenal gland, chloride depletion decreased angiotensin II receptors in the medulla and zona glomerulosa. Conversely, sodium depletion increased angiotensin II receptors in the zona glomerulosa. In the kidney glomeruli and medulla, angiotensin II receptors were decreased by either sodium or chloride depletion. These results suggest different roles for sodium and chloride in the regulation of the peripheral and central renin-angiotensin system in young rats.
Device Interoperability for Learned Image Compression with Weights and Activations Quantization (2022)

Learning-based image compression has improved to a level where it can outperform traditional image codecs such as HEVC and VVC in terms of coding performance. In addition to good compression performance, device interoperability is essential for a compression codec to be deployed, i.e., encoding and decoding on different CPUs or GPUs should be error-free and with negligible performance reduction. In this paper, we present a method to solve the device interoperability problem of a state-of-the-art image compression network. We implement quantization to entropy networks which output entropy parameters. We suggest a simple method which can ensure cross-platform encoding and decoding, and can be implemented quickly with minor performance deviation, of 0.3% BD-rate, from floating point model results.
Skierarchy: Extending the Power of Crowdsourcing Using a Hierarchy of Domain Experts, Crowd and Machine Learning. (2012)

Abstract : In the last few years, crowdsourcing has emerged as an effective solution for large-scale 'micro-tasks'. Usually, the micro-tasks that are accomplished using crowdsourcing tend to be those that computers cannot solve very effectively, but are fairly trivial for humans with no specialized training. In this work, we aim to extend the capability of crowdsourcing to tasks that are complex even from a human perspective. Towards this objective, we present a novel hierarchical approach involving a small number of domain experts at the top of the hierarchy, a large crowd with generic skills at the intermediate level, and a Machine Learning system serving as a personal assistant to the crowd, at the bottom level. We call this approach Skierarchy, short for Hierarchy of Skills. To test the efficacy of the Skierarchy approach, we deployed the model on the TREC 2012 TRAT task, a task we believe is fairly complex compared to typical micro-tasks. In this paper, we present illustrative experiments to demonstrate the utility of each of the layers of our hierarchy. Our experiments on TRAT as well as IRAT show that using an interactive process between the experts and the crowd could significantly reduce the need for redundancy among the crowd, while also enabling a crowd with generic skills to perform tasks that are reserved for specialists. Further, we found from our TRAT experience that both the crowd and the Machine Learning system improve their performance over time as they gain experience on specialized tasks.
