Application of Thermal Resistant Gemini Surfactants in Highly Thixotropic Water-in-oil Drilling Fluid System
Authors: Liu Yonggui , Zhang Yang , Yan Jing , Song Tao , Xu Yongjun 
Published: January 2020

AbstractTraditional water-in-oil drilling fluids are limited by their shear thinning behavior. In this article, we propose the synthesis of a thermal resistant quaternary ammonium salt gemini surfactant DQGE-I. This surfactant was synthesized using monomers such as N,N-dimethyl-1,3-propanediamine, organic acids and epichlorohydrin, as well as blocking groups such as N-vinylpyrrolidone (NVP). The prepared surfactant exhibited various advantages over traditional surfactants, including excellent thermal stability, good emulsifying and wetting capability. The use of these surfactants was shown to improve the compactness of emulsifier molecules at the oil/water interface, as well as the overall emulsificaiton effect. Laboratory studies revealed that water-in-oil emulsions prepared using DQGE-I showed high emulsion breaking voltage, low liquid precipitation and small and uniformly distributed emulsion drops. Highly thixotropic water-in-oil drilling fluids based on DQGE-I showed low viscosity, high shear rate and thermal tolerance up to 260oC. Additionally, the proposed fluid was applied in 16 wells (including WS1-H2, GS3 and XS1-H8) in the Daqing Oilfield. Testing showed that DQGE-1 exhibited excellent rheological behavior and wall-building capability. The emulsion breaking voltage exceeded 1500 V, and the yield point/ plastic viscosity ratio exceeded 0.4. The use of this surfactant can help to solve problems such as high formation temperature and poor well wall stability.
Technical Solutions for Legal Challenges: Equality of Arms in Criminal Proceedings
Authors: Quattrocolo Serena , Anglano Cosimo , Canonico Massimo , Guazzone Marco 
Published: January 2020

Abstract
The paper focuses on how computational models and methods impact on current legal systems, and in particular, on criminal justice. While the discussion about the suitabilty of the exploitation of learning machines and Artificial Intelligence (AI) either as surveillance means and human substitutes in the judicial decision-making process is arising, the authors reflect upon the risk of using AI and algorithm-based evidence in criminal proceedings. The claim of the paper is twofold: on the one hand, we should reinterpret todays legal frameworks, e. g. the European Convention of Human Rights, shifting the attention from possible violations of the right to privacy to potential infringements on a basic fair trial feature, the Equality of Arms. On the other hand, we should aknowledge that main legal issues, triggered by the breathtaking advancements in AI, can properly be addressed mainly through technical solutions (e. g. methods for assessing the completeness and correctness of digital evidence related to mobile devices and conversations). No legal theory, which overlooks the crossover of juridical and computational expertise, will survive the present time.
No Path to New Economics: John Komlos’s Foundations of Real-World Economics (Komlos 2019)
Authors: Gorbatenko Daniil 
Published: January 2020

Abstract
John Komlos’s Foundations of Real-World Economics is an ambitious book that aims at taking down the foundations of modern mainstream economics that students are taught at Econ 101 classes and replace them with a more reality-based alternative. However, Komlos’s falls way short of the stated objective. First, he fails to genuinely engage the introductory textbooks with which he supposedly argues. Komlos also appears to misunderstand the purpose of introductory-level economic models like perfect competition, as well as to entertain the idea that their rejection may lead to different conclusions from those that he seems to favor. Finally, Komlos does not cite sufficient research and evidence for his own potential building blocks for a new economics, such as the claim that the basic assumption of scarcity should be scrapped in favor of that of abundance.
Information Literacy Self-Efficacy of Business Students in Pakistan
Authors: Asif Naveed Muhammad , Mahmood Madiha 
Published: January 2020

AbstractThis study aimed to investigate the information literacy (IL) self-efficacy of business students in Pakistan using a cross-sectional survey research design. The data were collected through a questionnaire containing an information Literacy Self-Efficacy Scale along with personal and academic variables. The results revealed that the business students were confident and competent in basic IL skills whereas they were less comfortable in developing and limiting search strategies, referencing, managing citations, using different types of libraries and lacking advanced levels of IL skills. In addition, there was no correlation of students’ perceived IL self-efficacy with gender, social background, ICT trainings received, and IL instructions received. Conversely, the students’ age, program of study, stage of study, and ICT proficiency appeared to be predictors of IL self-efficacy. The results generated pragmatic insights which can be used as a guide in developing useful directions for a need-based information literacy curriculum as well as programs.
New handy and accurate approximation for the Gaussian integrals with applications to science and engineering
Authors: Sandoval-Hernandez Mario A. , Vazquez-Leal Hector , Filobello-Nino Uriel , Hernandez-Martinez Luis 
Published: January 2020

Abstract
In this work, we propose to approximate the Gaussian integral, the error function and the cumulative distribution function by using the power series extender method (PSEM). The approximations proposed in this paper present a high accuracy for the complete domain [–∞,∞]. Furthermore, the approximations are handy and easy computable, avoiding the application of special numerical algorithms. In order to show its high accuracy, three case studies are presented with applications to science and engineering.
Revenue Sharing Vertical Contracts in the Movie Industry: A Theoretical Analysis
Authors: Baranchuk Nina , Seetharaman Seethu , Strijnev Andrei 
Published: January 2020

Abstract
For many years, the movie industry has been characterized by a unique (compared to other industries) type of vertical contracting practice, called sliding-scale contracting whereby the distributor (studio) takes a much larger (usually around 70%) share of box-office revenues than the exhibitor (theater) in the week of a movie’s release, with the exhibitor’s share increasing, in gradual steps, over subsequent weeks. In this paper, we propose a game-theoretic model that provides a new rationale for these contracting choices. Specifically, we show that these contracts effectively resolve conflicts of interest between studios and theaters over movie release timing and display length, in a way that is beneficial for both parties. Our model also stipulates conditions under which sliding scale become dominated by aggregate deals, i.e. deals based on total rather than weekly box office revenue. The testable predictions based on these conditions can be used by future empirical research once the available evidence on the use of aggregate deals in practice goes beyond anecdotal.

AbstractTanning response and melanocyte differentiation are mediated by the central transcription factor MITF. This involves the rapid and selective induction of melanocyte maturation genes, while concomitantly the expression of other effector genes is maintained. In this study, using cell‐based and zebrafish model systems, we report on a pH‐mediated feed‐forward mechanism of epigenetic regulation that enables selective amplification of the melanocyte maturation program. We demonstrate that MITF activation directly elevates the expression of the enzyme carbonic anhydrase 14 (CA14). Nuclear localization of CA14 leads to an increase of the intracellular pH, resulting in the activation of the histone acetyl transferase p300/CBP. In turn, enhanced H3K27 histone acetylation at selected differentiation genes facilitates their amplified expression via MITF. CRISPR‐mediated targeted missense mutation of CA14 in zebrafish results in the formation of immature acidic melanocytes with decreased pigmentation, establishing a central role for this mechanism during melanocyte differentiation in vivo. Thus, we describe an epigenetic control system via pH modulation that reinforces cell fate determination by altering chromatin dynamics.

AbstractEpigenetic regulation is important for cancer progression; however, the underlying mechanisms, particularly those involving protein acetylation, remain to be fully understood. Here, we show that p300/CBP‐associated factor (PCAF)‐dependent acetylation of the transcription factor intestine‐specific homeobox (ISX) regulates epithelial–mesenchymal transition (EMT) and promotes cancer metastasis. Mechanistically, PCAF acetylation of ISX at lysine 69 promotes the interaction with acetylated bromodomain‐containing protein 4 (BRD4) at lysine 332 in tumor cells, and the translocation of the resulting complex into the nucleus. There, it binds to promoters of EMT genes, where acetylation of histone 3 at lysines 9, 14, and 18 initiates chromatin remodeling and subsequent transcriptional activation. Ectopic ISX expression enhances EMT marker expression, including TWIST1, Snail1, and VEGF, induces cancer metastasis, but suppresses E‐cadherin expression. In lung cancer, ectopic expression of PCAF–ISX–BRD4 axis components correlates with clinical metastatic features and poor prognosis. These results suggest that the PCAF–ISX–BRD4 axis mediates EMT signaling and regulates tumor initiation and metastasis.
PCAF, ISX, and BRD4: a maleficent alliance serving lung cancer malignancy
Authors: Stemmler Marc P 
Published: January 2020

Tumor progression and malignancy are frequently associated with aberrant activation of epithelial–mesenchymal transition (EMT), which orchestrates dramatic changes in gene expression, involving genetic and epigenetic regulation. External stimuli generated by tumor–stroma interactions need to be adequately processed to specifically alter expression of key EMT transcription factors and associated genes. In this issue of EMBO Reports, Wang and colleagues demonstrate how epigenetic modifiers are utilized to induce EMT and metastasis [1]. Acetylation of intestine‐specific homeobox (ISX) by p300/CBP‐associated factor (PCAF) induces a cascade that results in Snail and Twist activation through histone modifications by a novel complex of PCAF, ISX, and bromodomain‐containing protein 4 (BRD4). These findings open novel possibilities of therapeutic intervention to inhibit EMT and metastasis in lung cancer.
TheDrosophilaPost-mating Response: Gene Expression and Behavioral Changes Reveal Perdurance and Variation in Cross-Tissue Interactions

AbstractExamining cross-tissue interactions is important for understanding physiology and homeostasis. In animals, the female gonad produces signaling molecules that act distally. We examine gene expression in Drosophila melanogaster female head tissues in 1) virgins without a germline compared to virgins with a germline, 2) post-mated females with and without a germline compared to virgins, and 3) post-mated females mated to males with and without a germline compared to virgins. In virgins, the absence of a female germline results in expression changes in genes with known roles in nutrient homeostasis. At one- and three-day(s) post-mating, genes that change expression are enriched with those that function in metabolic pathways, in all conditions. We systematically examine female post-mating impacts on sleep, food preference and re-mating, in the strains and time points used for gene expression analyses and compare to published studies. We show that post-mating, gene expression changes vary by strain, prompting us to examine variation in female re-mating. We perform a genome-wide association study that identifies several DNA polymorphisms, including four in/near Wnt signaling pathway genes. Together, these data reveal how gene expression and behavior in females are influenced by cross-tissue interactions, by examining the impact of mating, fertility, and genotype.
Differences in the Receipt of Low-Value Services Between Publicly and Privately Insured Children
Authors: Chua Kao-Ping , Schwartz Aaron L. , Volerman Anna , Conti Rena M. , Huang Elbert S. 
Published: January 2020

BACKGROUND:
Children frequently receive low-value services that do not improve health, but it is unknown whether the receipt of these services differs between publicly and privately insured children.

METHODS:
We analyzed 2013–2014 Medicaid Analytic eXtract and IBM MarketScan Commercial Claims and Encounters databases. Using 20 measures of low-value care (6 diagnostic testing measures, 5 imaging measures, and 9 prescription drug measures), we compared the proportion of publicly and privately insured children in 12 states who received low-value services at least once or twice in 2014; the proportion of publicly and privately insured children who received low-value diagnostic tests, imaging tests, and prescription drugs at least once; and the proportion of publicly and privately insured children eligible for each measure who received the service at least once.

RESULTS:
Among 6 951 556 publicly insured children and 1 647 946 privately insured children, respectively, 11.0% and 8.9% received low-value services at least once, 3.9% and 2.8% received low-value services at least twice, 3.2% and 3.8% received low-value diagnostic tests at least once, 0.4% and 0.4% received low-value imaging tests at least once, and 8.4% and 5.5% received low-value prescription drug services at least once. Differences in the proportion of eligible children receiving each service were typically small (median difference among 20 measures, public minus private: +0.3 percentage points).

CONCLUSIONS:
In 2014, 1 in 9 publicly insured and 1 in 11 privately insured children received low-value services. Differences between populations were modest overall, suggesting that wasteful care is not highly associated with payer type. Efforts to reduce this care should target all populations regardless of payer mix.
Seismic Hazard Assessment in Australia: Can Structured Expert Elicitation Achieve Consensus in the “Land of the Fair Go”?
Authors: Griffin Jonathan D. , Allen Trevor I. , Gerstenberger Matthew C. 
Published: January 2020

AbstractThe 2018 National Seismic Hazard Assessment of Australia incorporated 19 alternative seismic-source models developed by members of the Australian seismological community. The diversity of these models demonstrates the deep epistemic uncertainty that exists with regards to how best to characterize seismicity in stable continental regions. In the face of similarly high uncertainty, a diverse range of ground-motion models was proposed for use. A complex logic tree was developed to incorporate the alternative component models into a single hazard model. Expert opinion was drawn upon to weight the alternative logic-tree branches through a structured expert elicitation process. Expert elicitation aims to transparently and reproducibly characterize the community distribution of expert estimates for uncertain quantities and thereby quantify the epistemic uncertainty around estimates of seismic hazard in Australia. We achieve a multimodel rational consensus in which each model, and each expert, is, in accordance with the Australian cultural myth of egalitarianism, given a “fair go”—that is, judged on their merits rather than their status. Yet despite this process, we find that the results are not universally accepted. A key issue is a contested boundary between what is scientifically reducible and what remains epistemologically uncertain, with a particular focus on the earthquake catalog. Furthermore, a reduction, on average, of 72% for the 10% in 50 yr probability of exceedance peak ground acceleration levels compared with those underpinning existing building design standards, challenges the choice of metrics upon which design codes are based. Both quantification of the bounds of epistemic uncertainties through expert elicitation and reduction of epistemic uncertainties through scientific advances have changed our understanding of how the hazard behaves. Dialog between scientists, engineers, and policy makers is required to ensure that as our understanding of the hazard evolves, the hazard metrics used to underpin risk management decisions are re-evaluated to ensure societal aims are achieved.
Analysis of Intraslab Predigital Earthquakes of the South-Central Alaska Region
Authors: Doser Diane I. 
Published: January 2020

Abstract
I compare intensity data from 17 predigital intraslab earthquakes in south-central Alaska and digitized waveforms for nine of these events to similar data for the 24 January 2016 Iniskin and 30 November 2018 Anchorage intraslab events. Both the 2016 and 2018 events were associated with amplification of strong ground motion at distances of over 100 km from their epicenters, likely due to the velocity structure associated with flat slab subduction in the region as well as the thick sedimentary sequence found within the Cook Inlet basin. Six of the predigital events also appear to have similar amplification of strong ground motion. Waveform comparisons suggest the 4 May 1934 Prince William Sound and 3 October 1954 Kenai Peninsula events had similar focal mechanisms and depths to the 30 November 2018 Anchorage event. Earthquakes occurring in regions where the P-wave velocity of the slab exceeds 7.5  km/s tend to be associated with higher strong ground motions.
The Word „master/Master” Sounds Strange…
Authors: Kabzińska Iwona 
Published: January 2020

The author avoids using the term master/Master, instead referring to the concept of a Teacher when describing the people who played a significant role in her life and who are the main protagonists of this article. These people are the Professors Anna Kutrzeba-Pojnarowa and Witold Dynowski, ethnologists, excellent lecturers and researchers; and also people full of passion, respect for the achievements of other scholars, fascinated with the history of the discipline they represent and the interrelation of “macro” and “micro” history. First and foremost, they are great PEOPLE. Reminiscing about encounters with them, the author presents the model relationship between a teacher and a pupil, close to her, which is not limited to passing knowledge. The relationship is based on kindness, openness to others, and motivating them to overcome their limitations, fears and difficulties. The skills of noticing the potential of others, encouraging them to develop, acceptance, keeping one’s spirits up, support and co-existence should also be mentioned.
Another person who also played the role of Teacher, although she has never been designated as such by the author, is her Grandmother Janina Orzechowska.
She was the one who shaped the author’s attitudes to life, her way of looking at other people, her passions and ways of being. She was the person whose selfless love expressed by her behavior, gestures and looks accompanied the author from an early age.
The motif of the relationship is very explicit in the text. The author emphasizes that relationships are not always joyful and constructive. Sometimes they clip one’s wings, they hurt and take away the light. Relationships which are beautiful in the beginning can also change under the influence of an illness, of one person affecting the others. The author describes changes like that via the example of the relationship with someone who appears in the text as the anonymous Teacher. It was a person from whom the author received a bitter lesson in life, far from fairy tales with a happy end.
Kajian Terhadap Ayat-Ayat I'jāz ‘Ilmiy Dalam Surah Al-Ra‘D

Published: January 2020

This article discusses one of the most important scientific disciplines in the Ulum al-Qurān namely i'jāz al-Qurān. Al-Qurān the book of Allah SWT which is the greatest and eternal miracle to the prophet Muhammad SAW. al-Qurān is the light of rabbani and divine revelation which gives guidance and guidance to all humans. He is a miracle of ruhiyyah akliyyah not hissiyyah. Allah has specified al-Qurān as an eternal miracle of reason throughout the ages so that it becomes the material for thought of scholars and scientists. Hopefully with this study humans can be enlightened rather than light, get benefits rather than clues to face the days ahead. In al-Qurān there are many forms of i'jāz including al-bayāniy, al-tashrī'iy, al-ghaibiy and al-'ilmiy. In this case the reviewers will focus the study of the miracles of al-Qurān from the point of i'jāz 'ilmiy in the surah al-Ra'd. This study refers to the qualitative method of inquiry, namely the analysis of the texts of the verses of al-Qurān surah al-Ra'd based on the books of muktabar interpretation. Apart from that modern science findings by scholars related were analyzed. The objective of the study is to explain the concept of i'jāz 'ilmiy.
