Sequence Mining and Pattern Analysis in Drilling Reports with Deep Natural Language Processing

Drilling activities in the oil and gas industry have been reported over decades for thousands of wells on a daily basis, yet little effort was made to analyze this text in large-scale for information retrieval, sequence mining, and pattern analysis. Drilling reports contain interpretations written by drillers from noting measurements in downhole sensors and surface equipment, and can be used for operation optimization and accident mitigation. In this initial work, a methodology is proposed for automatic classification of sentences written in drilling reports into three relevant labels (EVENT, SYMPTOM, and ACTION) for hundreds of wells in an actual field. Some of the main challenges in the text corpus were overcome, which include the high frequency of technical symbols, mistyping/abbreviation of technical terms, and the presence of incomplete sentences in the drilling reports. This work describes state-of-the-art classification accuracy obtained within this technical language and illustrates advanced queries enabled by the tool.
THE ASSOCIATION OF CRIME STORIES AND MAORI IN AOTEAROA NEW ZEALAND PRINT MEDIA

This paper explores associations between crime reporting and Maori ethnicity in a large representative sample of newspaper items gathered in Aotearoa New Zealand between November 2007 and April 2008, using content, thematic and discursive analyses and audience interpretations. The association of Maori and crime was prominent in these newspapers and Maori were frequently labelled as possible or actual perpetrators of crime on superficial judgements, often by victims. This practice associates Maori with all accounts of crime and embeds crime as a background for all other items about Maori. In contrast, newspaper coverage of Pakeha perpetrators of a crime against a Maori organisation worked to valorise the convicted thieves. This embedding of crime as a background to other stories about Maori, the pervasive but unacknowledged Pakeha1 norms, and media positioning of Maori as a threat in non-crime stories, is central to hegemonic discourses of Maori-Pakeha relations. Focus groups participants indicated that these discourses support real-world marginalisation and discrimination against Maori in Aotearoa New Zealand.
False suspicion and the misperception of deceit

Truth tellers may look dishonest when suspected of lying; if so, perceivers should be vulnerable to mistakes in recognizing the truth. In an experiment we find evidence of this error in truth detection. The error reflects a seeming confirmation of false accusations and is not merely a perceptual distortion. Affective and motivational explanations for the error are considered.
Linearization technique for stereophonic reproduction systems with nonlinearity

In this paper, we propose a novel linearization technique for stereophonic reproduction systems with nonlinearity by using the MINT and Volterra filters. In the proposed technique, the linearization is achieved by incorporating Volterra filters into the MINT, which can realize exact linear inverse filtering. The linearization performance of the proposed technique is consequently very high. The proposed technique can simultaneously linearize two loudspeaker systems in the stereophonic reproduction systems, also. On the other hand, the conventional linearization technique for monaural reproduction systems cannot realize exact linear inverse filtering. The linearization performance consequently deteriorates remarkably. Simulation results demonstrate that the proposed technique has about 20dB higher performance than the conventional one. The proposed technique also has smaller computational complexity than the conventional one.
Symptoms of anxiety and depression among Norwegian musicians compared to the general workforce

In order to investigate mental health problems among professional musicians, we estimate the prevalence of symptoms of anxiety and depression (psychological distress) among musicians compared to the general workforce. A total sample of 1,607 musicians from the Norwegian Musicians Union answered an online questionnaire about demographic characteristics, lifestyle and symptoms of anxiety and depression. They were compared to a sample of the Norwegian workforce (n = 2,550) drawn from the Norwegian survey of level of living 2012. Based on logistic regression analysis adjusting for age, sex, education level, smoking status, alcohol usage, use of drugs, physical exercise and financial status, we compared anxiety and depression symptom levels in musicians to a variety of professions. Psychological distress was more prevalent among musicians than in the total workforce sample. Solo/lead performers, vocalists, keyboard instrument players and musicians playing within the traditional music genre reported the highest prevalence. Further research needs to map the psychosocial and personal factors contributing to the higher degree of depression and anxiety symptoms among musicians, as well as establishing evidence-based preventative measures.
Cloning of the Amino-terminal and 5′-Flanking Region of the HumanMUC5AC Mucin Gene and Transcriptional Up-regulation by Bacterial Exoproducts*

To obtain gene regulatory sequence for the mucin gene MUC5AC, we have isolated the MUC5AC amino terminus cDNA and 5′-flanking region. This was possible through the use of rapid amplification of cDNA ends-polymerase chain reaction (RACE-PCR) in which the 5′ sequence of the human gastric mucin cDNA HGM-1 (1) was used to design the first MUC5AC-specific primer. Primers for subsequent rounds of RACE were designed from the 5′-ends of amplified RACE products. After five rounds of RACE-PCR, we could no longer generate upstream extensions of the cDNA and hypothesized that we had reached the 5′-end. Primer extension and RNase protection analysis confirmed this. Combined nucleotide sequence for the RACE-PCR products was 3.3 kb with an open reading frame encoding 1100 amino acids. A putative translation start site was found at nucleotide +48. This was followed by a 45 nucleotide putative signal sequence. This amino-terminal sequence contains no tandem repeats but is >60% similar to the amino-terminal nucleotide sequence ofMUC2. The positions of cysteine residues in thisMUC2-similar region are almost 100% conserved between the two genes. Northern analysis showed expression of cognate RNA in the stomach and airway but not muscle and esophagus. This pattern was the same as that obtained using previously reported 3′-MUC5ACsequences. We have cloned approximately 4 kb of genomic DNA upstream of the transcription start site and have sequenced 1366 nucleotides containing a TATA box, a CACCC box, and putative binding sites for NFκB and Sp 1. Within 4 kb of the transcription start site are elements mediating transcriptional up-regulation in response to bacterial exoproducts.
Theoretical Study of the Aspect Ratio of a Solar Still with Double Slopes

Clean water is essential for good health which influences the social and economic development of any nation. However, there is limited access to safe water on a global scale. This challenge can be overcome through a multi-faceted approach, including the development of appropriate technologies for water treatment and decision-making tools. Solar distillation is one of the commonest non-conventional methods for improving the quality of water. In this vein, the most widely-exploited solar distillation system is a conventional solar still, which has a thin layer of saline water in a shallow basin with a transparent cover over the water and one or two slopes. The productivity of a solar distillation system is influenced by design, climatic and operational factors, with solar radiation being the most influential meteorological parameter. It is therefore necessary to optimize solar radiation that effectively reaches the base of the solar still. Previous attempts have sought to improve the design characteristics of conventional solar stills through the consideration of system geometry and optical properties of construction materials. One of the important geometric parameters is the ratio (R) of length to width (aspect ratio) of the still base. For a single-slope solar still (SSS), R has been examined in preceding studies. Nevertheless, there is a paucity of information on the aspect ratio of a double-slope solar still. In this study, a state-of-the-art software (ESP-r) was used to simulate the variation of effective insolation with R for a double-slope solar still (DSS) in the east-west and north-south orientations and a SSS facing south. Meteorological data captured at the University of Strathclyde and Guantanamo Bay was employed in this analysis. Simulation results show that the optical performance of a DSS was lower (in both orientations) than that of a SSS at both sites. The DSS collected more solar energy in the east-west orientation than north-south orientation, for a given value of R. In addition, effective insolation increased with R to an optimum level for both the DSS and SSS. Approximate optimum values of R were 3.0 and 2.0 for the University of Strathclyde and Guantanamo Bay respectively. However, the optimum value of R was not sensitive to the orientation of the DSS at the two sitesFurther, the DSS and SSS exhibited the same optimal value of R at a specific site. It appears that R significantly affects solar collection in DSS.
Dynamic Statistics Collection in the Teradata Unified Data Architecture

The Unified Data Architecture (UDA) of Teradata is an inclusive multisystem data analytics solution. A key challenge for query optimization under the UDA is to find optimal plans for queries that access data on heterogeneous remote data stores. The challenge comes primarily from the lack of statistics for data stored on remote systems. In this paper, we present techniques implemented in Teradata Database for dynamically collecting statistics on data fetched from a remote system and feeding these statistics back to the query optimizer during query execution. We demonstrate the performance impact of dynamic statistics collection and feedback with experiments conducted on a system that consists of Teradata Database and a remote Hadoop server.

Persuading people in a remote destination to sing by beaming there

We built a Collaborative Virtual Environment (CVE) allowing one person, the 'visitor' to be digitally transported to a remote destination to interact with local people there. This included full body tracking, vibrotactile feedback and voice. This allowed interactions in the same CVE between multiple people situated in different physical remote locations. This system was used for an experiment to study whether the conveyance of touch has an impact on the willingness of participants embodied in the CVE to sing in public. In a first experimental condition, the experimenter virtually touched the avatar of the participants on the shoulder, producing vibrotactile feedback. In another condition using the identical physical setup, the vibrotactile displays were not activated, so that they would not feel the touch. Our hypothesis was that the tactile touch condition would produce a greater likelihood of compliance with the request to sing. In a second part we examined the hypothesis that people might be more willing to sing (execute an embarrassing task) in a CVE, because of the anonymity provided by virtual reality. Hence we carried out a similar study in physical reality. The results suggest that the tactile intervention had no effect on the sensations of body ownership, presence or the behaviours of the participants, in spite of the finding that the sensation of touch itself was effectively realised. Moreover we found an overall similarity in responses between the VR and real conditions.
Optimal PMU placement for power system state estimation with random communication packet losses

Phasor measurement units (PMUs) become important to state estimation for power systems by providing globally synchronized measurements of real-time phasors of voltage and currents with a high sampling rate. However the large quantities of measurement data produced by PMUs brings a serious burden to the communication system, which aggravates communication constraints such as the packet loss rate. In this paper, a novel optimization criterion for choosing PMU placements is proposed, considering random communication packet losses. Based on this criterion, a simplified optimal solution searching algorithm is given. Finally numerical simulations are given to test the validity of this algorithm. The dependence of the optimal PMU placement solution on the packet loss rate is indicated as well.
Effects of Spatial Ability, Gender Differences, and Pictorial Training on Children Using 2-D and 3-D Environments to Recall Landmark Locations From Memory

Abstract This study examines the effects of spatial ability, gender differences, and pictorial training on fourth grade students’ ability to recall landmark locations from memory. Ninety-six students used Google Earth over a 3-week period to locate landmarks (3-D) and mark their location on a 2-D topographical map. Analysis of covariance on posttest scores revealed that spatial ability was a significant predictor of student performance. The overall results support the efficacy of the instructional strategy and provide insight into the development of spatial knowledge among young children. Implications for the design of instruction and training on spatial abilities among young children are discussed.
A fully 5'-CG-3' but not a 5'-CCGG-3' methylated late frog virus 3 promoter retains activity

Several lines of evidence demonstrate that the DNA of the iridovirus frog virus 3 (FV3) is methylated in all 5'-CG-3' sequences both in virion DNA and in the intracellular viral DNA at late times after infection. The 5-methyldeoxycytidine residues in this viral DNA occur exclusively in 5'-CG-3' dinucleotide positions. We have cloned and determined the nucleotide sequence of the L1140 gene and its promoter from FV3 DNA. The gene encodes a 40-kDa protein. The results of transcriptional pattern analyses for this gene in fathead minnow fish cells document that this gene is transcribed exclusively late after FV3 infection. The L1140 gene and its promoter are fully methylated at late times after infection. We have been interested in resolving the apparent paradox that the methylated L1140 promoter is methylated and active late in FV3-infected cells. Of course, the possibility cannot be excluded that one or a few 5'-CG-3' sequences outside restriction endonuclease sites escaped de novo methylation after FV3 DNA replication. We have devised a construct that places the chloramphenicol acetyltransferase gene under the control of the L1140 promoter. Upon transfection, this construct exhibits activity only in FV3-infected BHK-21 hamster cells, not in uninfected BHK-21 cells. The fully 5'-CG-3' or 5'-GCGC-3' (HhaI) methylated, HpaII-mock-methylated, or unmethylated L1140 promoter-chloramphenicol acetyltransferase gene construct is active in FV3-infected BHK-21 cells, whereas the same construct 5'-CCGG-3' (HpaII) methylated has lost activity. Apparently, complete methylation of the late L1140 promoter in FV3 DNA is compatible with activity. However, a very specific 5'-CCGG-3' methylation pattern that does not naturally occur in authentic FV3 DNA in infected cells abrogates promoter function. These results further support the notion that very specific patterns of methylation are required to inhibit or inactivate viral promoters.
Feasibility of using computer-tailored and internet-based interventions to promote physical activity in underserved populations.

OBJECTIVE Computer-tailored and Internet-based interventions to promote physical activity behavior have shown some promise, but only few have been tested among African Americans. We examined the feasibility and efficacy of three 1-year, multiple contact physical activity interventions (Tailored Internet, Tailored Print, Standard Internet) in a subsample of African American participants (n = 38) enrolled in a randomized controlled trial. MATERIALS AND METHODS Participants randomly assigned to Tailored Internet and Print programs received individually tailored computer expert system feedback delivered via Internet or print. Participants in the Standard Internet program received access to six currently available physical activity Web sites. Self-reported physical activity was assessed at baseline and 6 and 12 months with the 7-Day Physical Activity Recall. RESULTS Across all participants, physical activity changed from 17.24 min/week (standard deviation [SD] = 20.72) at baseline to 139.44 min/week (SD = 99.20) at 6 months, to 104.26 min/week (SD = 129.14) at 12 months. According to available consumer satisfaction data (n = 30), 70% reported reading most or all of the physical activity information received by Internet or mail. Most participants described the Internet- and print-based physical activity programs as "somewhat" or "very" helpful (80%) and enjoyable (87%). CONCLUSIONS These findings suggest that computer-tailored and Internet-based interventions are able to produce long-term increases in physical activity and associated process variables among African American participants. Future studies with larger numbers of African American participants are needed to determine which of the programs (Tailored Print, Tailored Internet, Standard Internet) are more effective and what program modifications might be helpful in assisting this population in becoming more active.
Framing the Urban Hustler: Space and Identity Discourse in Kenyan Popular Music

Rapid urbanization in Africa has visited myriad challenges upon the inhabitants. This has led to the perception of African urban spaces as largely dysfunctional. However, this essay illustrates the existence of an intricate culture of resilience among contemporary urbanites. In Kenyan cities, this survival attitude is evident in the “hustler” mentality popularized through contemporary urban music. Musicians have creatively appropriated the otherwise negative hustler identity and redefined it for coping within a challenging urban context. This has consequently radically altered the way urban space functions and is perceived. The essay explores the dynamics of the social and spatial aspects of urban identity and how the city residents engage their geo-social landscape in an attempt to make the city work for them. To achieve an in-depth understanding of this phenomenon, eight “information-rich” songs by Kenyan urban musicians were purposively selected, and texts interpreted against the backdrop of theoretical discourses on the notions of space and identity. The findings lend credence to the assertions that in an urban environment, music exhibits socio-spatial implications and space influences identity formation among the dwellers.
Holiday Price Rigidity and Cost of Price Adjustment

The Thanksgiving-Christmas holiday period is a major sales period for US retailers. Due to higher store traffic, tasks such as restocking shelves, handling customers’ questions and inquiries, running cash registers, cleaning, and bagging, become more urgent during holidays. As a result, the holiday-period opportunity cost of price adjustment may increase dramatically for retail stores, which should lead to greater price rigidity during holidays. We test this prediction using weekly retail scanner price data from a major Midwestern supermarket chain. We find that indeed, prices are more rigid during holiday periods than non-holiday periods. For example, the econometric model we estimate suggests that the probability of a price change is lower during holiday periods, even after accounting for cost changes. Moreover, we find that the probability of a price change increases with the size of the cost change, during both, the holiday as well as non-holiday periods. We argue that these findings are best explained by higher price adjustment costs (menu cost) the retailers face during the holiday periods. Our data provides a natural experiment for studying variation in price rigidity because most aspects of market environment such as market structure, industry concentration, the nature of long-term relationships, contractual arrangements, etc., do not vary between holiday and nonholiday periods. We, therefore, are able to rule out these commonly used alternative explanations for the price rigidity, and conclude that the menu cost theory offers the best explanation for the holiday period price rigidity.
