Pick-ya actin – a method to purify actin isoforms with bespoke key post-translational modifications
Authors: Hatano Tomoyuki , Sivashanmugam Lavanya , Suchenko Andrejus , Hussain Hamdi , Balasubramanian Mohan K. 
Published: January 2020

ABSTRACT
Actin is one of the most abundant eukaryotic cytoskeletal polymer-forming proteins, which, in the filamentous form, regulates a number of physiological processes, ranging from cell division and migration to development and tissue function. Actins have different post-translational modifications (PTMs) in different organisms, including methionine, alanine, aspartate and glutamate N-acetylation, N-arginylation and the methylation of the histidine at residue 73 (His-73), with different organisms displaying a distinct signature of PTMs. Currently, methods are not available to produce actin isoforms with an organism-specific PTM profile. Here, we report the Pick-ya actin method, a method to express actin isoforms from any eukaryote with its own key characteristic PTM pattern. We achieve this using a synthetic biology strategy in a yeast strain that expresses, one, actin isoforms with the desired N-end via ubiquitin fusion and, two, mammalian enzymes that promote acetylation and methylation. Pick-ya actin should greatly facilitate biochemical, structural and physiological studies of the actin cytoskeleton and its PTMs.

Authors: Meyer Jean-Baptiste , Benguerna Mohamed 
Published: January 2020

Abstract
Higher education in Algeria is not well known in international spheres, apart from a few local studies. However, it is an exceptional case study for its outstanding achievements in recent history and particularly its growing pace. This article aims to describe the evolution of the higher education system at the country level through an analysis of national statistics gathered by the Ministry of Higher Education and Scientific Research (MESRS). The current article puts the case study in a historical perspective although concentrates on the most recent trends to describe the social issues at stake as a result of the introduction of current reforms and policies. The findings of the current study have been contextualized through different factors such as quality assessment and control, role of the private sector, international collaborations/integration, links with its economic and social environment and employability of students. Furthermore, this article also addresses the issue of the applicability of international norms within the higher education systems of developing countries. Finally, this article identifies and discusses the current developments in higher education that are changing in Algerian society today.
In search of a model to describe the organization of the Algerian diaspora networks
Authors: Nafa Aziz , Saad Mohammed 
Published: January 2020

Abstract
The problem of organizing the diaspora within and between networks has led to great interest among the scientific community. The literature has shown the existence of a real body and cohesion amongst the members of diasporas in the same country either at a regional or at a global scale, which organize, cooperate and act with the country of origin. This has led to some considerable material and immaterial advantages for the countries of origin. This state of affairs illustrates an inter-connection of the networks among the members, scattered over the four corners of the planet, but does not shed any light on the arrangement and functioning of the same networks within the country of origin. This research highlights the establishment of the Algerian business diaspora for the development of the entrepreneurship in Algeria. Beyond the business opportunity and the development of investment, there is also evidence of a clear involvement in extra-professional associative activities aimed at supporting entrepreneurship in Algeria and more particularly the innovative entrepreneurship. This qualitative research is based on the interviews of 36 entrepreneurs. The analysis of the interviews shows the existence of an innovative organization of networks and a hard core that is active in several forms of associations (Diaspora associations, Think-Tank, Business Angel, etc). This innovative organization of networks plays a significant role in the development of entrepreneurship in Algeria, in particular, the innovative entrepreneurship.
Tórtola Valencia, la performer: Sus acciones entre la danza y la performance fuera del escenario
Authors: Torrecilla Patiño Elia , Molina Alarcón Miguel 
Published: January 2020

En este artículo proponemos resaltar la figura de la misteriosa bailarina Tórtola Valencia y recuperarla en tanto sujeto-performerque utiliza la vida cotidiana como una danza (proto)performática. De manera alternativa a las danzas realizadas en los escenarios -La Maja, (Albéniz) La Danza de la gitana descalza (Saint-Saens),La Danza de Anitra (Grieg), La Marcha Fúnebre (Chopin), La Danza de los gnomos (Grieg), La danza de la serpiente (Delibes), La Danza del incienso (Buccalossi) o la Danza Árabe (Tchaikovsky), entre otras-, proponemos rescatar un conjunto de danzas performáticas derivadas de una actitud transgresora, que Tórtola realizó de forma espontánea fuera del escenario. Con sus acciones, Tórtola convirtió espacios como barcos, playas, cementerios o un campo de batalla en improvisados teatros donde llevar a cabo una comprensión de la vida como obra de arte, adelantándose en muchos casos a prácticas desarrolladas posteriormente y situadas entre el arte de la performancey la danza contemporñanea.

Restriction formula and subadditivity property related to multiplier ideal sheaves
Authors: Guan Qi’an , Zhou Xiangyu 
Published: January 2020

Abstract
We give a restriction formula on jumping numbers
which is a reformulation of Demailly–Ein–Lazarsfeld’s important restriction formula for multiplier ideal sheaves
and a generalization of Demailly–Kollár’s important restriction formula on complex singularity exponents,
and then we establish necessary conditions for the extremal case in the reformulated formula;
we pose the subadditivity property on the complex singularity exponents of plurisubharmonic functions
which is a generalization of Demailly–Kollár’s fundamental subadditivity property,
and then we establish necessary conditions for the extremal case in the generalization.
We also obtain two sharp relations on jumping numbers, introduce a new invariant of plurisubharmonic singularities and get its decreasing property for consecutive differences.

Published: January 2020

Introduction: Eustachian tube dysfunction is a common cause of morbidity in both adults and children, associated with nasal and otologic symptoms. Symptomatic evaluation is very important for the correct diagnosis and evaluation of the treatment efficacy of this entity. The “7-item Eustachian Tube Dysfunction Questionnaire” was described and validated by McCoul et al and proved to be a useful tool, easy to apply, with good validity in the evaluation of eustachian tube dysfunction symptoms. This study presents the validation process of the European Portuguese version of the “7-item Eustachian Tube Dysfunction Questionnaire”. The aim of this study was to translate and validate the European Portuguese version of “Eustachian Tube Dysfunction Questionnaire-7”.Material and Methods: The “7-item Eustachian Tube Dysfunction Questionnaire” was adapted and translated to European Portuguese using standard validation methodology. The European Portuguese version of “7-item Eustachian Tube Dysfunction Questionnaire” was completed by a group of 50 consecutive adult patients diagnosed with eustachian tube dysfunction and 25 healthy patients who served as a control group. All respondents in the Eustachian tube dysfunction group repeated the “7-item Eustachian Tube Dysfunction Questionnaire” in a two week-period. Statistical analysis was performed to determine its psychometric properties (reliability -internal consistency and test–retest reproducibility, and discriminant validity).Results: Face and content validity were confirmed, and reliability testing revealed similar internal consistency for the entire instrument as the original questionnaire, and strong correlation between individual items and total score. The questionnaire was easy and quick to administer. Test-retest reliability of the European Portuguese version was adequate, with excellent intraclass correlation coefficients and without significant differences between the total score from the first and second evaluations. Discriminative validity was confirmed by statistically significant differences between scores of the test and control groups.Discussion: This study presents the European Portuguese version of the “7-item Eustachian Tube Dysfunction Questionnaire” questionnaire, an adapted, validated and well-accepted instrument to evaluate the symptoms of eustachian tube dysfunction in the European Portuguese speaking population.Conclusion: The European Portuguese version of the “7-item Eustachian Tube Dysfunction Questionnaire” is recommended as a routine procedure in the assessment of patients with eustachian tube dysfunction in the European Portuguese speaking population and for the evaluation of treatment outcome.

Smart Assistant Guided Flowback Data Analysis
Authors: Miertschin Emma , Rasdi Faisal , Gupta Sidd , Anderson Seth , Jeyachandra Benin Chelinsky 
Published: January 2020

Abstract
The Oilfield is a cash flow dependent business, making the speed of decision-making very important. Our industry collects an incredible amount of data, but the volume of this data, coupled with inefficient oilfield software, slows down analysis and decision making. Critical decisions are delayed, and decision quality is affected.
Smart Assistants like Siri and Alexa have become extraordinarily popular lately due to their ability to perform routine tasks and make information readily accessible. Considering the oil industry's drive towards enhanced speed and efficiency, there is a considerable upside in applying the concept of a Smart Assistant to oil and gas applications. This Smart Assistant for Oil and Gas would consolidate massive amounts of data, derive knowledge from it, automate workflows, and provide faster and consistent insights.
This paper will look closely at a specific application of this Smart Assistant: analyzing flowback data from newly drilled wells. Engineers at Equinor have recently leveraged learnings from this Smart Assistant to increase efficiency in day-to-day tasks and realize results.
Developing Upscaling Approach for Swarming Hydraulic Fractures Observed at Hydraulic Fracturing Test Site Through Multiscale Simulations

Published: January 2020

Abstract
This work aims to address a challenge posed by recent observations of tightly-spaced hydraulic fractures in core samples from the Hydraulic Fracturing Test Site (HFTS). Many fractures in retrieved cores have sub-foot spacing, which is at odds with conventional models where usually one fracture is initiated per cluster. Since it is unrealistic to explicitly model all densely-spaced fractures, we develop a new upscaling law that enables existing simulation tools to predict reservoir responses to fracture swarms. The upscaling law is derived based on an energy argument and validated through multiscale simulations using a high-fidelity code, GEOS. The swarming fractures are first modeled with a spacing that is much smaller than the cluster spacing; these fractures are then approximated by an upscaled, single fracture based on the proposed upscaling law. The upscaled fracture is shown to successfully match the energy input rate and produce the total fracture aperture and average propagation length of the explicitly simulated swarm. Afterwards, the upscaling approach is further implemented in 3D field-scale simulations and validated against the HFTS microseismic data of a horizontal well in the Middle Wolfcamp Formation. Our results show that hydraulic fracture swarming can significantly affect fracture propagation behaviors compared with the propagation of single fractures as assumed by conventional modeling approaches. Under the considered situations, the conventional case entails fast propagation speed that far exceeds that indicated by the microseismic data. We also illustrate this discrepancy can be reduced readily through the implementation of the upscaling law. Our results demonstrate the importance of accounting for the fracture swarming effect in field-scale simulations and the efficacy of this approach to enable realistic predictions of reservoir responses to fracture swarms, without explicit modeling all tightly-spaced fractures observed in the field.
