Progress Review of the K&S Carbonated Waterflood Project (1960)

Abstract A carbonated waterflood process which comprises the treatment of a hydrocarbon reservoir with controlled amounts and concentrations of carbon dioxide is one of the newer methods of increasing oil recovery being used in a commercial field application. The process consists of the treatment of a crude-oil reservoir with controlled amounts and concentrations of carbon dioxide (CO2) or solutions of carbon dioxide. To achieve this end, the techniques of water flooding are combined with the injection of carbonated water into a reservoir during the early stage of the flood. The K and S project is the first commercial application of this process. Water injection was initiated on the and project in Feb., 1958, and CO2 injection started in April of the same year. The carbonation period should be completed by April 1, 1960. At this time it is too early to predict the ultimate oil recovery from the project. However, several notable accomplishments have been recorded to date. When the project was initially developed, several areas were noted to be highly water productive due to a previous dump flood. These areas subsequently have produced considerable oil, indicating that additional recovery has been gained. Second, injectivity has been increased to two to four times the rate of neighboring input wells which have not been subjected to the carbonated water process. And third, in 1959 more oil was produced than has been previously produced for the total primary life of the property. Introduction This paper is a progress report outlining the accomplishments and difficulties experienced to Jan. 1, 1960, at the K and S project. The K and S project is located 10 miles north of Bartlesville, Okla., and consists of three contiguous leases totaling 240 acres. There are 35 input wells and 24 producing wells spaced on a regular 10-acre five-spot pattern, as shown in Fig. 1. Water injection was initiated in Feb., 1958, and CO2 injection started in April of the same year. CO2 injection will be completed by April 1, 1960. Water injection will continue throughout the life of the project. The property was acquired in June, 1957. With 80 per cent of the working interest, Oil Recovery Corp. acts as engineering consultant and supervises the application of the process. Wellsville Oil Co., with the remaining 20 per cent of the working interest, is flood operator of the joint venture.

Panorama Stitching Based on SIFT Algorithm and Levenberg-Marquardt Optimization (2012)

Panorama stitching algorithm based on scale invariant feature transform and Levenberg-Marquardt optimiza-tion is proposed. Mapping the source planar images to a cylind-rical surface is the first step. Then, correct matching feature pairs are detected between two images by SIFT and RANSAC algorithm. Finally the Levenberg-Marquardt algorithm is used for calculating the initial estimates of motion parameters. Experiment results show that this method is effective against the hand-held camera motion with small rotation around the optical axis, small horizontal and vertical movement.
SDZ PSC 833 and SDZ 280–446 are the most active of various resistance-modifying agents in restoring rhodamine-123 retention within multidrug resistant P388 cells (1992)

Multidrug resistance (MDR) of tumor cells may result from overexpression of P-glycoprotein (Pgp) but may be down-modulated by resistance-modifying agents (RMAs). The cyclosporin SDZ PSC 833 and the cyclopeptolide SDZ 280-446 were found to be the strongest RMAs known to date for restoring the sensitivity of MDR cells to anticancer drugs, as well as for restoring their retention of daunomycin, a fluorescent anthracycline. Using rhodamine-123 (Rhod-123), another fluorescent probe of Pgp function which also differentiates sensitive and MDR cells, several RMAs were compared for their capacity to inhibit Pgp function. At variance with the data obtained with the daunomycin probe, a series of RMAs did not detectably restore Rhod-123 retention by the MDR cells. With the remaining RMAs, achieving the same levels of Rhod-123 retention required 3 times lower RMA concentrations when the RMA was added to the MDR cells for both the initial uptake and the efflux of Rhod-123 rather than for its uptake only. Nevertheless, the data emphasized the large superiority of SDZ PSC 833 and SDZ 280-446 over all other RMAs.

Remote PHY for Converged DOCSIS, Video, and OOB (2014)

Remote PHY refers to the technique of moving the PHY circuit out of a device such as a CCAP and putting the PHY circuit at the end of a network. Remote PHY builds upon the work started with Modular CMTS (MCMTS) and Modular Headend Architecture (MHA) at CableLabs. Remote PHY is an evolving set of specifications and products. This white paper will focus on the expanded definition and the updates to the transport and timing for Remote PHY and how they apply to DOCSIS, MPEG-TS video, and Out-of-Band signaling for STB.
Inactivation of the Enterobacter cloacae P99 .beta.-Lactamase by a Fluorescent Phosphonate: Direct Detection of Ligand Binding at the Second Site (1995)

The synthesis of a fluorescent beta-lactamase inhibitor, p-nitrophenyl [(dansylamido)methyl]-phosphonate is described. The compound inactivated the class C beta-lactamase of Enterobacter cloacae P99 with stoichiometric release of p-nitrophenol, presumably, as with other phosphonate inhibitors, by phosphonylation of the active site serine. The inhibited enzyme exhibited typical dansyl fluorescence emission at 533 nm with excitation maxima at 345 and 283 nm; the latter excitation peak probably arises from radiationless energy transfer to the dansyl group from aromatic chromophores on the protein-inspection of the crystal structure shows that the closest are tyrosines. The fluorescence of the p-nitrophenyl phosphonate and the inhibited enzyme varied with pH in a very similar fashion, reflecting dissociation of the dimethylammonium ion in the ground state at low pH and of the sulfonamide in the excited state above pH 6. No perturbation of the fluorescence of the inhibited enzyme due to active site functional groups was observed. This may reflect the distance between the dansyl fluorophore and the phosphonyl group and/or the high pKa's of the protonated active site functional groups in the presence of the phosphonate. The addition of certain small molecular weight N-acyl amino acids, of preferred structure D-RCONHCHR'CO2-, to the inhibited enzyme led to an enhancement of dansyl fluorescence intensity and a blue shift in the emission maximum. This suggested that these molecules bind to the beta-lactamase at a site other than the active site and supports previous kinetic data to this effect [Dryjanski, M., & Pratt, R. F., (1995) Biochemistry 34, preceding paper in this issue].(ABSTRACT TRUNCATED AT 250 WORDS)
Adherence to Postacute Rehabilitation Guidelines Is Associated With Functional Recovery in Stroke (2002)

Greater levels of adherence to postacute stroke rehabilitation guidelines were associated with improved patient outcomes. Compliance with guidelines may be viewed as a quality-of-care indicator with which to evaluate new organizational and funding changes involving postacute stroke rehabilitation.
Laser-induced acoustic landmine detection with experimental results on buried landmines (2004)

Acoustic landmine detection (ALD) is a technique for the detection of buried landmines including non-metal mines. Since it gives complementary results with GPR or metal detection, sensor fusion of these techniques with acoustic detection would give promising results. Two methods are used for the acoustic excitation of the soil: laser excitation and loudspeaker excitation. A promising concept is using lasers for excitation and monitoring for complete stand-off detection. Results from a field test and laboratory experiments show the feasibility of laser excitation for ALD. In these experiments buried landmine surrogates were measured with ALD using a Nd-YAG laser at 1.06 μm for the acoustic generation and a Laser Doppler Vibrometer (LDV) system at 1.54 μm for the detection of soil vibrations. An analysis is given of the experimental results showing the potential and the inherent limitations of the technique. We discuss the relative merits of LDV detection versus microphone detection of the laser-induced acoustic vibration. It was found that the LDV has limitations with respect to microphone detection due to the influence of surface effects that are prominent in LDV but absent in microphone detection.
Ultracold Atoms Spark a Hot Race (2003)

Making atoms in a gas pair like the electrons in a superconductor might lay bare the inner workings of high-temperature superconductors, neutron stars, and primordial matter--and perhaps win the creator of this much-anticipated atomic soup a Nobel Prize.
The changing face of emotion: age-related patterns of amygdala activation to salient faces (2010)

The present study investigated age-related differences in the amygdala and other nodes of face-processing networks in response to facial expression and familiarity. fMRI data were analyzed from 31 children (3.5-8.5 years) and 14 young adults (18-33 years) who viewed pictures of familiar (mothers) and unfamiliar emotional faces. Results showed that amygdala activation for faces over a scrambled image baseline increased with age. Children, but not adults, showed greater amygdala activation to happy than angry faces; in addition, amygdala activation for angry faces increased with age. In keeping with growing evidence of a positivity bias in young children, our data suggest that children find happy faces to be more salient or meaningful than angry faces. Both children and adults showed preferential activation to mothers' over strangers' faces in a region of rostral anterior cingulate cortex associated with self-evaluation, suggesting that some nodes in frontal evaluative networks are active early in development. This study presents novel data on neural correlates of face processing in childhood and indicates that preferential amygdala activation for emotional expressions changes with age.
A Watermarking Scheme for High Efficiency Video Coding (HEVC) (2014)

This paper presents a high payload watermarking scheme for High Efficiency Video Coding (HEVC). HEVC is an emerging video compression standard that provides better compression performance as compared to its predecessor, i.e. H.264/AVC. Considering that HEVC may will be used in a variety of applications in the future, the proposed algorithm has a high potential of utilization in applications involving broadcast and hiding of metadata. The watermark is embedded into the Quantized Transform Coefficients (QTCs) during the encoding process. Later, during the decoding process, the embedded message can be detected and extracted completely. The experimental results show that the proposed algorithm does not significantly affect the video quality, nor does it escalate the bitrate.

A study on tetrahedron-based inhomogeneous Monte Carlo optical simulation (2010)

Monte Carlo (MC) simulation is widely recognized as a gold standard in biophotonics for its high accuracy. Here we analyze several issues associated with tetrahedron-based optical Monte Carlo simulation in the context of TIM-OS, MMCM, MCML, and CUDAMCML in terms of accuracy and efficiency. Our results show that TIM-OS has significant better performance in the complex geometry cases and has comparable performance with CUDAMCML in the multi-layered tissue model.
Enzymatic hydrolysis of soy proteins and the hydrolysates utilisation (2011)

Soy proteins are very important protein source for human being and livestock. Enzymatic hydrolysis of soy protein can enhance or reduce its functional properties and improve its nutritious value. Soy protein hydrolysates were primarily used as functional food ingredients, flavour and nutritious enhancers, protein substitute, and clinical products. Conditions for hydrolysis were usually mild, whereas recently high pressure treatment attracted more interest. Degree of hydrolysis (DH) was usually between 1% and 39.5%. The main problem associated with proteolytic hydrolysis of soy protein was production of bitter taste, hydrolysates coagulation and high cost of enzymes. Bitterness reduction can be achieved by control of DH, selective separation of bitter peptides from hydrolysates, treatment of hydrolysates with exo-peptidases, addition of various components [adenosine monophosphate (AMP), some amino acids, monosodium glutamate (MSG), etc.] to block or mask the bitter taste, and modification of taste signalling. Hydrolysates coagulation can be resolved by selecting appropriate enzymes and by applying immobilisation technology the production cost can be reduced. Enzymatic hydrolysis also enhances bioactivity of soy proteins through conversion of glycosides to aglycones, increasing antioxidant and immunoregulatory properties. Finally, future works have been discussed.
Automatic Hypertext Construction (1995)

The unprecedented growth of the World Wide Web illustrates the importance of hypertext as a method for organizing the rapidly expanding amount of on-line text. As document collections become larger and more dynamic, however, it is not feasible to construct more than an occasional hypertext manually. This thesis presents entirely automatic methods for gathering documents for a hypertext, linking them, and annotating those connections with a description of the type or nature of the link. The problem of automatically collecting related documents is addressed in Chapter 2, where robust Information Retrieval methods are applied to form high-quality links between documents. A local context check identifies links where ambiguous vocabulary erroneously suggests a relationship. Dynamic part retrieval is employed to select the portions of documents which are most related, allowing parts to be linked when it is more appropriate to link subtopics than entire documents. Chapter 3 presents a taxonomy of hypertext link types and defines the following three classes of links: "pattern-matching" links can be found using simple string-matching methods, "manual" links require substantial application of natural language understanding methods (which are currently beyond the state of the art), and "automatic" links are those which can be found using the methods of this thesis. Chapter 4 begins the work of automatic link typing by describing two novel graphical techniques for visualizing the relationship between two or more documents. "Uniform" visuals display the relationship between documents or document parts without regard to their relative sizes, whereas "varying" visuals include information about sizes and locations. Both methods highlight relationships between documents and motivate the automatic techniques of Chapter 5. Chapter 5, thus, demonstrates automatic methods for identifying the relationships depicted in the visualizations. Using an approach based upon graph simplification, this method automatically identifies revision, summary, expansion, equivalence, comparison, contrast, tangential, and aggregate links. Chapter 6 discusses an informal evaluation of the link typing. Though somewhat inconclusive, the evaluation demonstrates that automatic document linking performs well, but also indicates that much work remains to be done toward understanding automatic link typing.
Bent Ladder-Type Hexaphenylene with Carbazole Core and Spiro Linkage as Stable and Efficient Blue Emitter (2009)

A bent ladder-type hexaphenylene with a carbazole core and spiro-linkage is designed and synthesized by using the ortho-linked spirobifluorene. The design eliminates the possibility of forming a positional isomer. As a blue-emitter, the BLHPC shows good thermal and color stability. A simple light-emitting device fabricated from BLHPC exhibits a maximum current efficiency of 1.46 cd/A and a maximum luminance of 505 cd/m(2).
Security monitoring based on joint automatic speaker recognition and blind source separation (2014)

The aim of this paper is to introduce an enhanced approach for standard Automatic Speaker Recognition (ASR) systems in noisy environment in conjunction with a Blind Source Separation (BSS) algorithm. This latter is able to discern between interfering noise signals and the reference speech signal, hence it can be consider as a necessary preprocessing step. The main problem of the proposed approach lies in the not removable ambiguities typically of the BSS algorithms. In order to overcome to this drawback, a geometrical constraint is also added to the learning algorithm. A practical example shows the effectiveness of the proposed approach in terms of recognition accuracy.
Neutron radiographs using the ionographic process (1978)

Thermal neutron radiographs have been made using ionographic techniques. With a fluence of 107 neutrons/cm2 at the image plane, image resolution of three line pairs per mm was demonstrated. The apparatus for these demonstration experiments is described, and alternative modes of operation are discussed. It appears possible to make ionographic neutron radiographs using a transmitted fluence of 106 neutrons/cm2.
Using document classification for displaying search results lists (2003)

In this paper, four self-developed user interfaces that display document search results using different methods were compared. In order to create the four interfaces, two information elements: document categories and lines from the document were used. A user study compared the four interfaces. It was found that the category addition to the interface was beneficial in both measurable and subjective measures. It was also found that displaying the relevant lines from the document increased the effectiveness and shortened the search time in all cases and tasks. It was found that the participants preferred the interface containing categories and relevant lines to all other interfaces checked. It was also the fastest in the objective time measurement. Another sub-research that was conducted showed that the most important parameter for the users was the confidence level that the answer was accurate, and the least important parameter was the feeling of comfort while conducting a search.
Antagonism in isolated equine digital vessels of contraction induced by epinephrine in the presence of hydrocortisone and an aqueous extract of black walnut (<i>Juglans nigra</i>) (1989)

Prazosin, isoxsuprine, and nifedipine were screened for ability to reverse contraction of isolated equine digital vascular strips produced by epinephrine (Epi) in the presence of hydrocortisone (Hc) and an aqueous extract of black walnut (Juglans nigra) (BW). Two arteries and two veins from each of three horses for each drug (n = 9) were maintained in isolated tissue baths in Krebs' bicarbonate buffer with 95% oxygen at 37 degrees C. Six-point Epi concentration-response (C-R) curves were obtained for each vessel in the presence of Hc, BW, and the appropriate vehicle. This was repeated for each vessel using one of two concentrations of one of the three test drugs. Each drug and concentration combination was tested on a total of three arteries and three veins. Prazosin produced a concentration-dependent shift of the Epi C-R curve to the right but the curve maintained the same maximum height and slope, which is consistent with competitive alpha 1 adrenergic blockade. Isoxsuprine exhibited similar behavior, although the precise mechanism of action for isoxsuprine is unknown. Conversely, nifedipine did not shift the curve but did depress maximum contraction, suggesting a non-competitive interaction consistent with its mechanism of calcium-channel blockade.

Programming the Web: the W3C DOM specification (1999)

Developers manipulating Web documents to provide user interaction need a standard interface to those documents. The paper discusses the W3C Document Object Model Level 1 which defines the standardized interface. The DOM Level 1 defines a language- and platform-neutral API for accessing, navigating and manipulating HTML and XML documents. As such, it is a foundation for the development of applications that use Web documents in an object-oriented paradigm.
