How “deep” is Dynamism? Revisiting the evaluation of Moroccan-flavored Netherlandic Dutch
Authors: Grondelaers Stefan , van Gent Paul 
Published: April 2019

Abstract
In this paper we report a new speaker evaluation experiment to follow up on an earlier study, which found that the Moroccan accent of Netherlandic Standard Dutch was generally downgraded. As in the previous study, both traditional Superiority evaluations and modern Dynamism considerations (pertaining to media cool) were extracted, albeit with greater methodological care: we included a three-level accent strength variable in the stimuli, and measured Dynamism-evaluations on independently validated scales. While mildly accented Moroccan-Dutch speech was deemed less inferior than its strongly accented counterpart (though not as superior as any indigenous speech), Moroccan-flavoured speech was found to be the most dynamic in general. It is argued that the new data account for the increasing vitality of Moroccan-accented speech much better than previous findings, but also, and contrary to previous claims, that the Dynamism evaluations which power this vitality are not implicit or subconscious.

Abstract
Hall effect based Teslameters/Gaussmeters measure DC and AC magnetic flux densities in the range from a few µT to about 30 T. For accurate measurement a 3-axis Hall probe is applied with small magnetic field sensitive volume (MFSV) of 100 µm × 10 µm × 100 µm, with vertical and horizontal Hall elements integrated on a single chip. The planar Hall effect, that produces additional measurement errors is suppressed by the spinning current technique. The orthogonality error of the 3-axis Hall probe is reduced to smaller than 0.1° by the described calibration procedure. This paper explains why the above features are crucial for some applications in industry and modern science for accurate measurement of inhomogeneous magnetic fields and how to achieve them. The future technology trends in magnetic metrology are introduced and the newly developed Nanomapper that incorporates a 3-axis Hall probe with a MFSV of smaller than 10×10×10 micrometer is presented.
Synchronicity: The Role of Midbrain Dopamine in Whole-Brain Coordination
Authors: Beeler Jeff A. , Kisbye Dreyer Jakob 
Published: April 2019

AbstractMidbrain dopamine seems to play an outsized role in motivated behavior and learning. Widely associated with mediating reward-related behavior, decision making, and learning, dopamine continues to generate controversies in the field. While many studies and theories focus on what dopamine cells encode, the question of how the midbrain derives the information it encodes is poorly understood and comparatively less addressed. Recent anatomical studies suggest greater diversity and complexity of afferent inputs than previously appreciated, requiring rethinking of prior models. Here, we elaborate a hypothesis that construes midbrain dopamine as implementing a Bayesian selector in which individual dopamine cells sample afferent activity across distributed brain substrates, comprising evidence to be evaluated on the extent to which stimuli in the on-going sensorimotor stream organizes distributed, parallel processing, reflecting implicit value. To effectively generate a temporally resolved phasic signal, a population of dopamine cells must exhibit synchronous activity. We argue that synchronous activity across a population of dopamine cells signals consensus across distributed afferent substrates, invigorating responding to recognized opportunities and facilitating further learning. In framing our hypothesis, we shift from the question of how value is computed to the broader question of how the brain achieves coordination across distributed, parallel processing. We posit the midbrain is part of an “axis of agency” in which the prefrontal cortex (PFC), basal ganglia (BGS), and midbrain form an axis mediating control, coordination, and consensus, respectively.

AbstractGenome-wide assessment of genetic diversity has the potential to increase the ability to understand admixture, inbreeding, kinship and erosion of genetic diversity affecting both captive (ex situ) and wild (in situ) populations of threatened species. The sable antelope (Hippotragus niger), native to the savannah woodlands of sub-Saharan Africa, is a species that is being managed ex situ in both public (zoo) and private (ranch) collections in the United States. Our objective was to develop whole genome sequence resources that will serve as a foundation for characterizing the genetic status of ex situ populations of sable antelope relative to populations in the wild. Here we report the draft genome assembly of a male sable antelope, a member of the subfamily Hippotraginae (Bovidae, Cetartiodactyla, Mammalia). The 2.596 Gb draft genome consists of 136,528 contigs with an N50 of 45.5 Kbp and 16,927 scaffolds with an N50 of 4.59 Mbp. De novo annotation identified 18,828 protein-coding genes and repetitive sequences encompassing 46.97% of the genome. The discovery of single nucleotide variants (SNVs) was assisted by the re-sequencing of seven additional captive and wild individuals, representing two different subspecies, leading to the identification of 1,987,710 bi-allelic SNVs. Assembly of the mitochondrial genomes revealed that each individual was defined by a unique haplotype and these data were used to infer the mitochondrial gene tree relative to other hippotragine species. The sable antelope genome constitutes a valuable resource for assessing genome-wide diversity and evolutionary potential, thereby facilitating long-term conservation of this charismatic species.

Stress echocardiography is an established technique for the assessment of extent and severity of coronary artery disease. The combination of echocardiography with a physical, pharmacological or electrical stress allows detecting myocardial ischemia with an excellent accuracy. A transient worsening of regional function during stress is the hallmark of inducible ischemia. Stress echocardiography provides similar diagnostic and prognostic accuracy as radionuclide stress perfusion imaging or magnetic resonance, but at a substantially lower cost, without environmental impact, and with no biohazards for the patient and the physician. The evidence on its clinical impact has been collected over 35 years, based on solid experimental, pathophysiological, technological and clinical foundations. There is the need to implement the combination of wall motion and coronary flow reserve, assessed in the left anterior descending artery, into a single test. The improvement of technology and in imaging quality will make this approach more and more feasible. The future issues in stress echo will be the possibility of obtaining quantitative information translating the current qualitative assessment of regional wall motion into a number. The next challenge for stress echocardiography is to overcome its main weaknesses: dependence on operator expertise, the lack of outcome data (a widespread problem in clinical imaging) to document the improvement of patient outcomes. This paper summarizes the main indications for the clinical applications of stress echocardiography to ischemic heart disease.

Published: April 2019

The article presents a clinical case of embolism with bone cement of the right ventricle of the heart and pulmonary artery after percutaneous vertebroplasty in a patient aged 63 years. According to the results of a comprehensive examination using ultrasound and x-ray methods, three foreign bodies were found: in the right ventricle cavity, in the trunk of the pulmonary artery, in the branches of the left pulmonary artery. Considering the stable condition, normal blood oxygen saturation, the lack of influence of formations on intracardiac hemodynamics, it was decided to refrain from surgery, since the risk of intervention exceeded the possible benefit. Conservative treatment tactics and dynamic observation were chosen. The literature data on the frequency of such events and tactics of management of these patients are presented.

Published: April 2019

Introduction: Laparoscopic cholecystectomy has become the procedure of choice for the management of symptomatic gallstone disease. Difficulty in laparoscopic cholecystectomy is often encountered by surgeons and is associated with complications and a higher conversion rate. This study aims at identifying difficult laparoscopic cholecystectomies by clinical and imaging assessment and determining the utility of a pre-operative difficulty scoring system based on intra-operative findings.
PATIENTS and METHODS: A hospital based observational study was conducted including all patients above age 18 years undergoing laparoscopic cholecystectomy. Randhawa’s preoperative score was calculated for every patient based on history, clinical and imaging parameters and the degree of operative difficulty was predicted. Another scoring was done using Sugrue’s scoring system based on intra-operative findings. The outcome factors studied were degree of operative difficulty or need for conversion and intra-operative and post-operative complications. The statistical analysis was done by using EPI INFO software version 7.
RESULTS: A total 84 patients with mean age 42.96 +14.34 years with 58 females and 26 males were enrolled. Of them 28 (33.33%) had difficult laparoscopic cholecystectomies. The conversion rate to open cholecystectomy was 9.52%. Age above 50 years, prior history of acute cholecystitis, thickened gall bladder wall and stone impaction of Hartmann’s pouch were statistically significant pre-operative risk factors. The sensitivity of the preoperative score in identifying difficult cases was 85.7% with the specificity of 96.43%; positive predictive value of 92.31% and the negative predictive value of 93.10% and the accuracy was 92.86%.
CONCLUSION: Pre-operative score and intra-operative findings are helpful in identifying difficult laparoscopic cholecystectomy.
Quality of Life and its Relation to Creative Thinking among a Sample of Female Adolescents in Jeddah

Published: April 2019

The study of subjective well-being in adolescence has had recent and dynamic growth, however, there are still few qualitative studies that contribute to getting to know about and discussing the sociocultural diversity of well-being, in particular ones that consider the socioeconomic status of the studied groups.
The purpose of this study is to prove that Quality of Life plays a large role in an individual’s Creative Thinking abilities.
Two hundred sixty-four female middle-school students (first, second and third grades) in Saudi Arabia, aged 12-15 were chosen randomly for participation in this study. The students were then subjected to Quality of Life Scale (QOL) and The Torrance Tests of Verbal Creative Thinking.
The results showed quite a few differences regarding the group’s Quality of Life and Creative Thinking Scores. There was a positive statistically significant correlation of 0.01 between the “family and social life”, “general health”, the total degree of Quality of Life perceived and Creative Thinking. On the other hand, there was no statistically significant correlation between “Time management” and the total and subscales of the Creative Thinking Scale. The results also showed that there is a statistically positive effect at 0.05 level of Quality of Life on Creative Thinking, where the value of the beta coefficient is 0.36 proving that Creative Thinking can be predicted by Quality of Life.
The findings suggest that the Quality of Life represented in home and school environments, and health in general does influence creative thinking in adolescents. These points raise important issues in relation to Creative Thinking by implying that fostering creative thinking of adolescents requires a suitable environment.

Published: April 2019

Intelligent mobile robots need self-localization, map generation, and the ability to explore unknown environments autonomously. Probabilistic processing can be applied to overcome the problems of movement uncertainties and measurement errors. Probabilistic robotics and simultaneous localization and mapping (SLAM) technologies are therefore strongly related, and they have been the focus of many studies. As more and more practical applications are found for intelligent mobile robots, such as for autonomous driving and cleaning, the applicability of these techniques has been increasing.
In this special issue, we provide a wide variety of very interesting papers ranging from studies and developments in applied SLAM technologies to fundamental theories for SLAM. There are five academic papers, one each on the following topics: first visit navigation, controls for following rescue clues, indoor localization using magnetic field maps, a new solution for self-localization using downhill simplex method, and object detection for long-term map management through image-based learning. In addition, in the next number, there will be a review paper by Tsukuba University’s Prof. Tsubouchi, who is famous for the Tsukuba Challenge and research related to mobile robotics.
We editors hope this special issue will help readers to develop mobile robots and use SLAM technologies and probabilistic approaches to produce successful applications.
Co-Production to Overcome Water Influx in Alaskan Reservoir

Published: April 2019

ABSTRACT
The Sterling B4 sands is a reservoir underlain by an aquifer located on the Kenai Peninsula of Alaska. This dry gas-on-water reservoir, holding approximately 13.9 billion cubic feet (Bcf), has experienced challenges since its first development in the 1960s. The gas-water contact is very mobile and easily influenced upward by gas production. All four wells, largely producing in succession of one another, have experienced excessive water production which killed gas production. Faulty drilling and completion work exacerbated the challenges associated with bringing the gas to market.
This paper summarizes an effort to model the Sterling B4 development and determine feasible alternatives for revival of the reservoir and commercialization of the produced gas. Those alternatives include infill drilling, variable production, and co-production. Co-production is a method by which gas is produced from the gas zone and water is produced from the water zone; each stream is produced independently by either mechanical means or different wells.
The only feasible alternative found in this study is co-production. Of the two co-production methods analyzed, the highest ultimate recovery includes the utilization of an existing vertical well perforating the upper portion of the reservoir for gas production and a new lower horizontal well perforating the water zone to control the gas-water contact. Modeled production schemes proved the gas-water contact may be controlled from upward mobility by maintaining a threshold pressure difference between the bottom-hole pressures of the two producing wells. Utilizing co-production in this manner yielded incremental benefit of over 2 Bcf until shut-in limits were triggered, achieving an ultimate recovery of up to 43%.
Economic analysis of the project has proved bringing the gas to market presents a significant prize able to support production and full facility operational expense despite no other revenue streams. Should other nearby formations demonstrate sufficient targets, the economic case would be enhanced and present an even greater prize.
How Big Data Analytics Can Help Future Regulatory Issues in Carbon Capture and Sequestration CCS Projects

Published: April 2019

Abstract
In this age of data, there is a significant need for tracking and prediction of non-compliance of rules & regulations in various industries including the oil & gas sector. In this paper, we will be reviewing some of the anticipated regulatory issues in commercial implementations of carbon capture & sequestration (CCS) and discuss how machine learning and big data analytics can diminish future non-compliance incidents.
With the rising awareness of advanced data-driven technologies such as "Big Data Analytics" and "Machine Learning", a contemporary approach to regulation and compliance is developing. This emerging approach, called "Algorithmic Regulation", defines an alternative framework for systematic collection of data (real-time or near real-time) and continuous generation of knowledge through intelligent computational algorithms in order to regulate a domain of activities.
In this study, we will look at some of the major data management challenges in the pilot CCS operations with regards to rules and regulations. We will then discuss how an algorithmic regulatory framework can help in conducting CCS operations in a manner that are compliant with environmental, safety and health policies and regulations.
Field operators collect a lot of data which needs to be formatted and modelled in a fashion acceptable to understand the operator's compliance with regulation. Generally, such compliance qualification criteria are verified using human intellect and basic querying software. In other industries, the idea of converting rules & regulations in a format understandable by machines is gaining momentum and great strides have been taken. The technological progresses made possible by data-driven analytical techniques can create a paradigm shift in the way rules and regulations are designed and implemented. Large-scale deployment of CCS projects is bound to bring with it a number of regulatory issues, making it a necessity to proactively explore and address the anticipated issues. These technologies can equip regulated entities as well as regulators with advanced tools for managing complexity in CCS projects. These improved solutions will help companies to better meet the regulatory data collection, reporting and governance requirements in large scale CCS operations.
This paper looks into advanced data management and modeling techniques like "algorithmic regulations" to increase compliance in carbon capture and sequestration projects. The concept of handling rules and regulations in the form of big data will change the outlook and compliance management will become increasingly more agile and responsive.
