Modeling the Role of Wettability Alteration with Brine Composition and Increased Oil Recovery from Carbonate Cores (2016)

Abstract Laboratory studies have shown that certain modifications to the ionic composition of the injection water increase oil recovery from carbonates. The impact of salinity is related to wettability alteration of the system toward more water wetness, demonstrated by a reduction in the measured oil-water contact-angles. It is not confirmed that the wettability shift contributes to all or most of the oil recovery increase. This is mainly because conventional multiphase fluid flow simulators, commonly used to predict oil recovery, do not incorporate directly the role of wettability conditions and contact-angles. This paper provides a new method to estimate the additional oil recovery that results from wettability alteration of carbonate cores. A pore network model (PNM) was used to predict relative permeability curves at different wettability conditions. The effect on oil recovery was quantified from imbibition relative permeability curves that were generated from the PNM. These curves were used to simulate displacements. The simulation was run using a brine tracking function that estimates the instantaneous relative permeability based on tracing the injection brine salinity. The proposed approach was applied to the experimental core-flood experiments reported by Alshakhs and Kovscek (2015a). The PNM was constructed for a representative bimodal carbonate system. A drainage capillary pressure curve from a mercury injection experiment guided the construction of the static model structure. The static PNM model generated two relative permeability sets that correspond to contact-angles of 95° and 55°. The simulation results showed comparable additional oil recovery to observations from the experimental core-flood experiments, 7.5% compared to 6.4%, respectively. The good match supports that the additional oil recovery is mainly attributed to wettability alteration.
[Metabolic evaluation of recurrent idiopathic calcium stone disease in Portugal]. (2006)

Among the studied population, idiopathic calcium nephrolithiasis affected both genders equally. Metabolic evaluation permits the identification of urine abnormalities in most of these patients. Hyperoxaluria, hypercalciuria, hypocitraturia and hyperuricosuria appeared as important pathogenic factors in IRCSF. Urine volume was not different between groups. Dietary factors may be involved in the observed urine abnormalities and need to be further evaluated.
Social TV (2012)

We link the content of real-time social media response to characteristics of the Super Bowl 2012 TV advertisements, including their advertisers' social media strategies and the categories of the products being advertised. We analyze millions of social media posts about approximately forty-five advertisements during the 2012 Super Bowl. While there are many studies that focus on the popularity of and sentiment of response to Super Bowl ads, we believe ours is the first to go deeper and analyze the textual "content" to understand better the factors contributing to specific types of social media responses among a number of TV advertising dimensions. In this study, we show that the level of online consumer engagement, measured by attracting new followers on Twitter during the Superbowl, can be linked to whether the brand that advertised had a social media strategy or not. In addition, we show that sentiment response, a measure often use to quantify the effectiveness of TV ads, varies by demographic category.
PROCESSING TECHNOLOGIES FOR FERROELECTRIC THIN FILMS AND HETEROSTRUCTURES (1998)

▪ Abstract Basic scientific and technological advances on ferroelectric thin films and heterostructures are discussed in relation to the work on nonvolatile ferroelectric random access memories (NVFRAMs) performed by different groups during the last seven years. A reasonable understanding of the synthesis and microstructure-property relationships of ferroelectric thin films for NVFRAMs is demonstrated. Materials integration strategies developed to fabricate ferroelectric capacitors with practically no fatigue or imprint, long polarization retention, and low leakage current are discussed. These properties have been obtained using two ferroelectric materials, Pb(Zr x Ti 1−x )O 3 (PZT) and SrBi 2 Ta 2 O 9 (SBT), that are the main candidates for application to the first generation of commercial NVFRAMs. A discussion of current knowledge and future research directions is presented.
Development of functional cosmetic ingredients using lactic acid bacteria in Japan (2007)

Fermentation technology involving lactic acid bacteria (LAB) is known to be useful for producing or improving the function of many kinds of cosmetic ingredients. In Japan as of 2006, a total of 45 cosmetic ingredients were manufactured using various LAB fermentation including filtrates and production of fermented substrates by LAB. Numerous cosmetic ingredients displaying new functions may result from information on commercial cosmetic ingredients using fermentation technology of LAB and from various published patent applications on cosmetic development. Advances in LAB science are continuously being used to improve the safety and function of cosmetic ingredients, and these ingredients are expected to keep skin healthier and slow skin aging processes.
A Critical Review of Proactive Detection of Driver Stress Levels Based on Multimodal Measurements (2018)

Stress is a major concern in daily life, as it imposes significant and growing health and economic costs on society every year. Stress and driving are a dangerous combination and can lead to life-threatening situations, evidenced by the large number of road traffic crashes that occur every year due to driver stress. In addition, the rate of general health issues caused by work-related chronic stress in drivers who work in public and private transport is greater than in many other occupational groups. An in-vehicle warning system for driver stress levels is needed to continuously predict dangerous driving situations and proactively alert drivers to ensure safe and comfortable driving. As a result of the recent developments in ambient intelligence, such as sensing technologies, pervasive devices, context recognition, and communications, driver stress can be automatically detected using multimodal measurements. This critical review investigates the state of the art of techniques and achievements for automatic driver stress level detection based on multimodal sensors and data. In this work, the most widely used data followed by frequent and highly performed selected features to detect driver stress levels are analyzed and presented. This review also discusses key methodological issues and gaps that hinder the implementation of driver stress detection systems and offers insights into future research directions.

Speechbot: an experimental speech-based search engine for multimedia content on the web (2002)

As the Web transforms from a text-only medium into a more multimedia-rich medium, the need arises to perform searches based on the multimedia content. In this paper, we present an audio and video search engine to tackle this problem. The engine uses speech recognition technology to index spoken audio and video files from the World Wide Web (WWW) when no transcriptions are available. If transcriptions (even imperfect ones) are available, we can also take advantage of them to improve the indexing process. Our engine indexes several thousand talk and news radio shows covering a wide range of topics and speaking styles from a selection of public Web sites with multimedia archives. Our Web site is similar in spirit to normal Web search sites; it contains an index, not the actual multimedia content. The audio from these shows suffers in acoustic quality due to bandwidth limitations, coding, compression, and poor acoustic conditions. Our word error rate (WER) results using appropriately trained acoustic models show remarkable resilience to the high compression, although many factors combine to increase the average WERs over standard broadcast news benchmarks. We show that, even if the transcription is inaccurate, we can still achieve good retrieval performance for typical user queries (77.5%).
NOD mice have a generalized defect in their response to transplantation tolerance induction. (1999)

A protocol consisting of a single donor-specific transfusion (DST) plus a brief course of anti-CD154 monoclonal antibody (anti-CD40 ligand mAb) induces permanent islet allograft survival in chemically diabetic mice, but its efficacy in mice with autoimmune diabetes is unknown. Confirming a previous report, we first observed that treatment of young female NOD mice with anti-CD154 mAb reduced the frequency of diabetes through 1 year of age to 43%, compared with 73% in untreated controls. We also confirmed that spontaneously diabetic NOD mice transplanted with syngeneic (NOD-Prkdc(scid)/Prkdc(scid)) or allogeneic (BALB/c) islets rapidly reject their grafts. Graft survival was not prolonged, however, by pretreatment with either anti-CD154 mAb alone or anti-CD154 mAb plus DST. In addition, allograft rejection in NOD mice was not restricted to islet grafts. Anti-CD154 mAb plus DST treatment failed to prolong skin allograft survival in nondiabetic male NOD mice. The inability to induce transplantation tolerance in NOD (H2g7) mice was associated with non-major histocompatibility complex (MHC) genes. Treatment with DST and anti-CD154 mAb prolonged skin allograft survival in both C57BL/6 (H2b) and C57BL/6.NOD-H2g7 mice, but it was ineffective in NOD, NOD.SWR-H2q, and NOR (H2g7) mice. Mitogen-stimulated interleukin-1beta production by antigen-presenting cells was greater in strains susceptible to tolerance induction than in the strains resistant to tolerance induction. The results suggest the existence of a general defect in tolerance mechanisms in NOD mice. This genetic defect involves defective antigen-presenting cell maturation, leads to spontaneous autoimmune diabetes in the presence of the H2g7 MHC, and precludes the induction of transplantation tolerance irrespective of MHC haplotype. Promising islet transplantation methods based on overcoming the alloimmune response by interference with costimulation may require modification or amplification for use in the setting of autoimmune diabetes.
PERCENTAGE OF POSITIVE LEFT VENTRICULAR HYPERTROPHY IN ANAEROBIC, AEROBIC, AND SEDENTARY MALES (2013)

Davis, Cassandra, Hill, Aimee, Knabe, Chelsey, and advisor Dr. Steve Burns; University of Central Missouri, Warrensburg, Missouri Different intensities of exercise such as aerobic and anaerobic activities may have different effects on the heart. The aim of this research was to explore the differences of aerobic, anaerobic, and sedentary lifestyles on left ventricular hypertrophy (LVH) and QRS axis. PURPOSE: The purpose of this study was to discover if aerobic athletes, anaerobic athletes or sedentary individuals have different Electrocardiograms. METHODS: Ten sedentary males ages 18-25 volunteered for this study and underwent a resting 12-lead EKG assessment. EKGs previously conducted in 2011 from football (anaerobic n=12) and cross country (aerobic n=10) males were used to determine heart axis and left ventricular hypertrophy (LVH) of the heart. LVH was determined by a subject meeting the criteria for one of the three formulas. Formulas were: sum of the depth of S wave in V1 + height of R wave in V5 or V6 > 35mm, R wave in lead aVL > 11-13mm, and increased QRS voltage measured as the R wave in the lead I + S wave in lead III ≥ 25mm. The QRS axis was determined by using the Hexaxial Diagram. Normal QRS axis ranges from -30°-(+100°). RESULTS: Left ventricular hypertrophy was observed in 30% of anaerobic athletes (3/10), 25% of the aerobic athletes (3/12), and 20% of the sedentary group (2/10). The mean QRS axis was 82.5 for anaerobic and aerobic athletes and 70.2 for the sedentary group. CONCLUSION: The anaerobic group had a higher percentage of subjects that were positive for LVH. There seems to be more cases of LVH in anaerobic than aerobic to be LVH positive. The QRS was in the normal range for all three groups.
Non-malleable non-interactive zero knowledge and adaptive chosen-ciphertext security (2003)

We introduce the notion of non-malleable non-interactive zero-knowledge (NIZK) proof systems. We show how to transform any ordinary NIZK proof system into one that has strong non-malleability properties. We then show that the elegant encryption scheme of Naor and Yung (1990) can be made secure against the strongest form of chosen-ciphertext attack by using a non-malleable NIZK proof instead of a standard NIZK proof. Our encryption scheme is simple to describe and works in the standard cryptographic model under, general assumptions. The encryption scheme can be realized assuming the existence of trapdoor permutations.

Counterfactual Data Augmentation for Mitigating Gender Stereotypes in Languages with Rich Morphology (2019)

Gender stereotypes are manifest in most of the world's languages and are consequently propagated or amplified by NLP systems. Although research has focused on mitigating gender stereotypes in English, the approaches that are commonly employed produce ungrammatical sentences in morphologically rich languages. We present a novel approach for converting between masculine-inflected and feminine-inflected sentences in such languages. For Spanish and Hebrew, our approach achieves F1 scores of 82% and 73% at the level of tags and accuracies of 90% and 87% at the level of forms. By evaluating our approach using four different languages, we show that, on average, it reduces gender stereotyping by a factor of 2.5 without any sacrifice to grammaticality.
RAVI, a proposed standard for the interchange of audio/visual interactive applications (1990)

RAVI (representation for audio/visual interactive applications), a set of specifications proposed as a standard for the interchange of audio/visual interactive applications (AVIs), is presented. RAVI was designed to meet the functional requirements of an AVI. RAVI consists of an interchange format and a set of functional operators (formulation). Protocols for a RAVI system are defined to allow communication between distributed subsystems. RAVI profiles allow compatible implementation of restricted sets of functionalities. As far as possible, the RAVI specifications use existing standards and are being submitted to ISO and CCITT for discussion. Products are commercially available, and a number of applications has already been developed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Slow Glucose Removal Rate and Hyperinsulinemia Precede the Development of Type II Diabetes in the Offspring of Diabetic Parents (1990)

One to two decades before type II diabetes is diagnosed, reduced glucose clearance is already present. This reduced clearance is accompanied by compensatory hyperinsulinemia, not hypoinsulinemia, suggesting that the primary defect is in peripheral tissue response to insulin and glucose, not in the pancreatic beta cell.

Terrain segmentation of high resolution satellite images using multi-class AdaBoost algorithm (2014)

Terrain segmentation is still a challenging issue in pattern recognition, especially in the application of high resolution satellite images. Among the various segmentation approaches are those based on graph partitioning, which present some drawbacks such as high processing time, low accuracy on detection of targets on the large scaled images such as high resolution satellite images. In this paper, we focus on the computational intelligence approach to classify and detect building, foliage, grass, bare-ground, and road of land cover. We propose a method, which has a high accuracy on classification and object detection by using multi-class AdaBoost algorithm based on a combination of two extracted features, which are cooccurrence and Haar-like features. With all features, multi-class Adaboost selects only critical features and performs as an extremely efficient classifier. Experimental results show that the classification accuracy is over 91% with a high resolution satellite image.
Slow vibrational relaxation in picosecond iodine recombination in liquids (1982)

A characteristic time scale of order 100 ps has been observed by several workers in picosecond spectroscopy experiments on iodine recombination in liquid CCl4 and other solvents. This time scale has been thought to be associated with the diffusive relative motion, prior to actual recombination, of photodissociated I atoms. In this paper, we point out that extensive vibrational deactivation of nascent iodine molecules formed in the recombination is required for spectroscopic detection of I2. We propose that slow vibrational relaxation of nascent I2 may play an important role in such recombination studies. We examine the relaxation of highly vibrationally excited I2 in liquid CCl4. Both vibrational-translational (VT) and vibrational–vibrational (VV) energy transfer mechanisms are considered. We estimate that the characteristic time scale for the vibrational relaxation of I2 in CCl4 is of order 100 ps. VV energy transfer is found to play a critical role in the relaxation. Possible experimental avenues for testing our conclusions are suggested.
The EPR D-parameter of 1,3-diarylcyclopentane-1,3-diyl triplet diradicals as a probe for steric substituent effects in benzyl-type radicals † (1999)

The zero-field splitting D parameter of a set of ortho-substituted 1,3-diarylcyclopentane-1,3-diyl triplet diradicals 3 has been determined by EPR spectroscopy in a 2-methyltetrahydrofuran glass matrix at 77 K. While for meta- and para-substituted triplet diradicals 3 the D parameter is only a function of the electronic nature (spin donor versus spin acceptor) of the substituent, for the ortho-substituted derivatives the steric influence must also be considered. We show herein that the steric effect of the ortho substituent diminishes delocalization of the cumyl spin density into the aromatic ring through twisting of the π system out of conjugation with the cumyl radical center; indeed, the steric effect may outweigh the electronic influence of the substituent. The computed (PM3) spin density of the minimum-energy conformer reproduces well the experimentally observed steric effect on the D parameter of the triplet diradicals 3. These results demonstrate that the EPR-spectroscopic D parameter serves as a sensitive probe for steric as well as electronic substituent effects.
Oxygen deficient perovskites: effect of structure on electrical conductivity, magnetism and electrocatalytic activity. (2019)

The present thesis deals with the synthesis and study of the physico-chemical properties of perovskite based oxide materials. Several novel oxygen deficient perovskites (ODP) have been synthesized by conventional solid state synthesis method. The novel compounds are CaSrFe2O6-δ, CaSrFeCoO6-δ, Ca2Fe1.5Ga0.5O5, CaSrFeGaO5 and BaSrFe2O5. Their magnetic, charge transport and electrocatalytic properties have been studied. Structural effect on electrical conductivity, magnetic and electrocatalytic properties have been studied in some series of ODPs. CaSrFe2O6-δ, CaSrFeCoO6-δ, Ca2Fe1.5Ga0.5O5 and CaSrFeGaO5 have brownmillerite type orthorhombic structures with layered structure having alternate tetrahedral and octahedral layers which are connected to one another by corner sharing. These are vacancy ordered compounds. BaSrFe2O5 is vacancy disordered compound with cubic structure. Most of the studied materials exhibited G-type long range antiferromagnetic arrangement of magnetic moments. During the study of charge transport property, compounds with structural order in a particular series show relatively less conductivity at room temperature and semiconductive nature and transition to metallic conductivity during temperature dependent conductivity measurement. Vacancy disordered compounds show relatively higher conductivity at room temperature and show mixed (semiconductive and metallic) conductivity during temperature dependent conductivity measurement. The study of electrocatalytic properties revealed the relation with the conductivity and the structural order. The electrocatalytic activity toward oxygen evolution reaction is highly efficient if the material is highly conductive or highly ordered.
