Since the nonlocality comes in the decomposition of the space directly, we introduce a new fractional center of mass, via a suitable seminorm. Some other delicate aspects arise strictly related to the presence of the nonlocal operator. By using regularity results based on fractional De Giorgi classes, we show that the found solutions decay polynomially and concentrate around some point of K for ε small.
Study abroad, language usage, and the development of multilingual identities: The case of 1.5 generation Korean–American students
Authors: Lee Hakyoon , Kim YouJin , Choi Bumyong 
Published: November 2020

AbstractThis one-year longitudinal case study investigates two 1.5 generation Korean–American students’ Korean language learning and usage before, during, and after their study abroad (SA) trip to Korea. Each came to the U.S. at eight years old for primary education and currently attends a university in the U.S. Their linguistic and cultural backgrounds brought intragroup diversities into their educational communities, including the study abroad program. With detailed documentation of interview data and ethnographic field notes, this study examines how learning Korean influences the construction of the learner’s self. This study also seeks to identify the ways that concepts of language learning, multilingual identities, and cultural belonging can be elucidated using narrative analysis. The participants’ post-sojourn experiences reveal SA creates an opportunity to develop cultural membership and to build multilingual identities with increased accessibility to the Korean communities. This study offers a nuanced understanding of the diversifying study abroad students in higher education in the U.S., and the mobilization of linguistic resources and the construction of identities in the context of study abroad.
Classroom Composition and Student Academic Achievement: The Impact of Peers’ Parental Education
Authors: Wang Tianheng 
Published: November 2020

Abstract
Using data from a nationally representative survey of middle school students in China and exploiting the random assignment of students to classrooms within schools, the study investigates the causal effect of peers’ parental education on students’ scholastic performance. The results show that the education level of peers’ parents improves students’ academic achievement. Students with high-educated parents benefit more from classmates with higher parental education compared to students with low-educated parents. The investigation of mechanisms reveals that the peer effects could be in part explained by peers’ academic quality, classroom atmosphere, and behaviors of students’ friends. However, peers’ parental education has no impact on teachers’ pedagogical methods and teaching efforts. The paper also shows that failing to account for the nonrandom assignment of students within schools causes an upward bias in the estimated peer effects of parental education.

Published: November 2020

Abstract
Even though seaweeds have been recognized as key players in the ocean-to-atmosphere transfer of iodine in other parts of the world, there is a complete lack of knowledge about iodine accumulation in seaweeds of the Arabian Gulf. Similarly, very little is known about fluorine in seaweeds, anywhere in the world. Given that the Arabian Gulf is of particular interest due to being an extreme environment, featuring some of the highest temperatures and salinities observed in any marine water body worldwide, this study endeavoured to conduct a preliminary survey of iodine and fluorine levels in 11 of the most common seaweed species in the region, supported by morphological and molecular (DNA barcode)-based identification. Iodine was determined by inductively-coupled plasma-mass spectrometry, while ion chromatography was employed for analysis of fluoride. Species surveyed included Iyengaria stellata, Padina boergesenii, Chondria sp.

Secure Incident & Evidence Management Framework (SIEMF) for Internet of Vehicles using Deep Learning and Blockchain
Authors: Philip A. Oommen , Saravanaguru RA K 
Published: November 2020

AbstractEven though there is continuous improvement in road and vehicle safety, road traffic incidents have been increasing over last few decades. There is a need to reduce traffic incidents like accidents through predictive analysis and timely warnings while at the same time data related to accidents and traffic violations need to be maintained in a tamper proof storage system that can be retrieved for forensic analysis and law enforcement at a later stage. The Secure Incident and Evidence Management Framework (SIEMF) proposed in this work address these two challenges of predictive modeling for timely warning and secure evidence management for forensics analysis in case of accidents and traffic violations. The system proposes a deep learning based predictive incident modeling with blockchain and CP-ABE based access control for the incident data stored in blockchain.

Abstract
In this study, the simulation of the natural gas liquids (NGLs) of Siri Island unit was carried out using Aspen Hysys software. Energy and economic evaluation of these towers were evaluated with Aspen Energy Analyses and Aspen Economic Evaluation, respectively. The effect of various parameters such as the use of heat exchanger instead of a cooler, feed tray changes and the mixing of two feed streams together were investigated to increase the efficiency of hydrocarbons - (Ethane, Propane, Butane, and Pentane) separation, utility consumption and costs. The simulation results showed that the input feed stream from the 10-tray using - mixing of two input 207 and 208 streams, which improves the efficiency of hydrocarbons gas separation and utility consumption compared to other parameters.
Lagrangian cobordism and tropical curves
Authors: Sheridan Nick , Smith Ivan 
Published: November 2020

Abstract
We study a cylindrical Lagrangian cobordism group for Lagrangian torus fibres in symplectic manifolds which are the total spaces of smooth Lagrangian torus fibrations. We use ideas from family Floer theory and tropical geometry to obtain both obstructions to and constructions of cobordisms; in particular, we give examples of symplectic tori in which the cobordism group has no non-trivial cobordism relations between pairwise distinct fibres, and ones in which the degree zero fibre cobordism group is a divisible group. The results are independent of but motivated by mirror symmetry, and a relation to rational equivalence of 0-cycles on the mirror rigid analytic space.

Abstract

Objectives
The diagnostic process is a vital component of safe and effective emergency department (ED) care. There are no standardized methods for identifying or reliably monitoring diagnostic errors in the ED, impeding efforts to enhance diagnostic safety. We sought to identify trigger concepts to screen ED records for diagnostic errors and describe how they can be used as a measurement strategy to identify and reduce preventable diagnostic harm.

Methods
We conducted a literature review and surveyed ED directors to compile a list of potential electronic health record (EHR) trigger (e-triggers) and non-EHR based concepts. We convened a multidisciplinary expert panel to build consensus on trigger concepts to identify and reduce preventable diagnostic harm in the ED.

Results
Six e-trigger and five non-EHR based concepts were selected by the expert panel. E-trigger concepts included: unscheduled ED return to ED resulting in hospital admission, death following ED visit, care escalation, high-risk conditions based on symptom-disease dyads, return visits with new diagnostic/therapeutic interventions, and change of treating service after admission. Non-EHR based signals included: cases from mortality/morbidity conferences, risk management/safety office referrals, ED medical director case referrals, patient complaints, and radiology/laboratory misreads and callbacks. The panel suggested further refinements to aid future research in defining diagnostic error epidemiology in ED settings.

Conclusions
We identified a set of e-trigger concepts and non-EHR based signals that could be developed further to screen ED visits for diagnostic safety events. With additional evaluation, trigger-based methods can be used as tools to monitor and improve ED diagnostic performance.
From subcategories to the entire module categories
Authors: Hafezi Rasool 
Published: November 2020

Abstract
In this paper we show that how the representation theory of subcategories (of the category of modules over an Artin algebra) can be connected to the representation theory of all modules over some algebra. The subcategories dealing with are some certain subcategories of the morphism categories (including submodule categories studied recently by Ringel and Schmidmeier) and of the Gorenstein projective modules over (relative) stable Auslander algebras. These two kinds of subcategories, as will be seen, are closely related to each other. To make such a connection, we will define a functor from each type of the subcategories to the category of modules over some Artin algebra. It is shown that to compute the almost split sequences in the subcategories it is enough to do the computation with help of the corresponding functors in the category of modules over some Artin algebra which is known and easier to work. Then as an application the most part of Auslander–Reiten quiver of the subcategories is obtained only by the Auslander–Reiten quiver of an appropriate algebra and next adding the remaining vertices and arrows in an obvious way. As a special case, when Λ is a Gorenstein Artin algebra of finite representation type, then the subcategories of Gorenstein projective modules over the

Who is Going to Pay for Causing Pandemics?
Authors: Regaldo Federico 
Published: November 2020

Abstract
In the modern, globalized, world, millions of laws and statutes are applicable to humankind, in order to curb and regulate the activity of every individual. Within the last decades, sanctions multiplied and aggravated, but who is going to pay for having caused a catastrophic pandemic? Actually, it seems that the answer is: “nobody”. However, the article gives some suggestion, by applying new “eco-tort” and civil liability principles to this new and unprecedented crisis. Furthermore, it gives some urgent public policy guidelines to minimize the risk of new pandemics. It also advocates a new world order, based on the promotion of anti-speciesism, non-violence, environmental protection and fair sharing of natural resources, while rejecting the free market theories: it seems the best way for finally overcoming the crisis and preventing new ones.
Localized boundary-domain singular integral equations of the Robin type problem for self-adjoint second-order strongly elliptic PDE systems
Authors: Chkadua Otar , Mikhailov Sergey , Natroshvili David 
Published: November 2020

Abstract
The paper deals with the three-dimensional Robin type boundary-value problem (BVP) for a
second-order strongly elliptic system of partial differential
equations in the divergence form with variable coefficients. The problem is studied by the localized parametrix based potential method.
By using Green’s representation formula and properties of the localized layer and volume
potentials, the BVP under consideration is reduced
to the a system of localized boundary-domain singular integral equations (LBDSIE).
The equivalence between the original boundary value problem and the corresponding LBDSIE system is established.
The matrix operator generated by the LBDSIE system belongs to the Boutet de Monvel algebra.
With the help of the Vishik–Eskin theory based on the Wiener–Hopf factorization method, the Fredholm properties of the corresponding localized boundary-domain singular integral operator are investigated
and its invertibility in appropriate function spaces is proved.
Wood identification of two anatomically similar Cupressaceae species based on two-dimensional microfibril angle mapping
Authors: Kita Yusuke , Sugiyama Junji 
Published: November 2020

Abstract
Identifying two anatomically similar species of Cupressaceae, Chamaecyparis obtusa and Thujopsis spp., is important to better understand the culture of wood use in Japan. However, the conventional method, which involves observing their cross-field pitting, cannot identify them in many cases. This study solves the above problem by introducing an anatomical criterion based on the micro fibril angle (MFA). MFA values were obtained through two-dimensional MFA images using the uniaxial optical anisotropy of cellulose microfibrils. A combination of the preprocessed MFA images and a convolutional neural network (CNN) yielded an accuracy nearly of 90% in classifying these species in cases of present and old wood specimens. Our feature extraction and classification techniques provide a new way for describing the anatomical features of wood and identifying featureless softwoods. Using the model interpretation-related methodologies of the CNN, distinct features of the two wood species were partly explained by MFA anisotropy in the S2 wall induced by the existence of pits.
Effect of cerium on the initiation of pitting corrosion of 444-type heat-resistant ferritic stainless steel
Authors: Ma Mingyu , Liu Houlong , Chen Liqing 
Published: November 2020

AbstractThe 444-type heat-resistant ferritic stainless steel is widely utilized in automotive exhaust pipes and solid oxide fuel cells, due to its excellent properties at elevated temperature. To meet the demands of significantly harsh service environments, rare earths were added in 444-type ferritic stainless steel. For the purpose of evaluating the effect of rare earths on pitting corrosion initiation, the metastable pitting corrosion behavior in 444-type ferritic stainless steel was studied through potentiodynamic polarization and potentiostatic polarization tests. The results demonstrated that pitting corrosion was initiated at the inclusion/alloy interface. The cerium alloying in 444-type ferritic stainless steel decreased the amount of preferential dissolution sites. The beneficial effect of Ce on pitting corrosion resulted from the formation of stable cerium oxides, as well as from the reduction in the amount and size of inclusions in 444-type ferritic stainless steel. In addition, electrochemical impedance spectroscopy test results revealed that cerium alloying enhanced the polarization resistance of passive films through insignificant thickness alteration.
Dephosphorization of hot metal using rare earth oxide-containing slags
Authors: Ye Maolin , Xi Xiaojun , Yang Shufeng , Li Jingshe , Wang Feng 
Published: November 2020

AbstractAn innovative rare earth oxide-containing slag for hot metal dephosphorization was proposed, and the factors influencing the efficiency during the dephosphorization of hot metal using rare earth oxide-containing slags were also studied. An increase in the temperature up to 1,550°C is beneficial to the dephosphorization process, and the maximum degree of dephosphorization for slags containing 6 wt% rare earth oxides is 44.49%; further temperature increases would deteriorate the efficiency, and the degree of dephosphorization decreases to 37.38% at 1,600°C. An increase in the basicity of slags up to 3.0, and the rare earth oxide content up to 6 wt%, improves the dephosphorization efficiency; further increase in the basicity and rare earth oxide content, the efficiency has almost no change. It was also found that an increase in the quantity of slags is beneficial to the dephosphorization reaction.
The last verse of the Middle Phrygian epigram from Dokimeion
Authors: Obrador-Cursach Bartomeu 
Published: November 2020

Abstract
This paper focuses on the last verse of the Phrygian epigram dated to the Early Hellenistic Period and found in Dokimeion (W-11). After some remarks on the segmentation, the verb πεννιτι is identified as the Phrygian outcome of PIE verbal root *pent- and ομνισιτου, along with its related Phrygian forms, as going back to PIE *h₃emh₃‑. It also argues in favour of Lubotsky’s identification of Phrygian κορο- as a cognate of Greek κόρος ‘boy’ and κόρη ‘girl’ with some remarks on its inflection.
Mihi est from Brythonic to Breton I
Authors: Rezac Milan 
Published: November 2020

Abstract
Middle Breton (MB) presents a singular anomaly of pronominal argument coding. Objects are accusative proclitics save in two constructions, where coding is split by person: 3rd unique enclitics ~ 1st/2nd accusative proclitics. The constructions are HAVE, from Insular Celtic mihi est, where the new coding replaces inflectional nominatives (cf. Latin mihi est ~ sunt); and imperatives, where it replaces accusative enclitics in V1 (cf. French aide-moi ~ ne m’aide pas). The evolution is traced in light of a crosslinguistic construction type that suggests its nature, noncanonical subject + 3rd nominative ~ 1st/2nd accusative object. Part I: (1) Decomposition of HAVE as dative clitic + BE from Brythonic throughout “conservative” varieties of Breton. (2) Breton-Cornish innovation of nonclitic datives for mihi est and their subjecthood. Part II: (3) Brythonic unavailibility of mesoclisis in V1 and Breton-Cornish nonagreement with nominative objects, resulting in independent > enclitic pronouns for accusative objects of imperatives and nominative objects of mihi est. (4) MB alignment of imperatives with mihi est in 3rd person, restriction on nominative enclitics, and recruitment of 1st/2nd person accusative proclitics upon loss of mesoclisis. (5) Transition to accusative objects in “innovative” varieties and subject-object case interactions.
The process of capacity-building for pediatric subspecialty providers to address the needs of adolescents and young adults with chronic illness
Authors: Quimby Dakari , Conn Bridgid M. , Ellis Tierra T. , Iverson Ellen 
Published: November 2020

Abstract
Approximately 12% of adolescents in the USA live with a chronic health condition. Although youth with chronic illness visit healthcare providers more than healthy peers, pediatric subspecialty providers are less likely to address developmentally relevant concerns (e.g., reproductive health) with adolescents and young adults (AYA), particularly youth of color and/or youth in low-income communities. Despite the documented need for increased training, there remains a general lack of knowledge about pediatric subspecialty providers’ training needs related to building their capacity to provide developmentally appropriate care to their adolescent and young adult patients. The present study describes an overall process for capacity-building to address the needs of diverse AYA patients with chronic medical conditions, built upon data representing key stakeholders and staff from 14 specialty care departments collected via quantitative surveys and focus groups. We describe the development of trainings for pediatric subspecialty providers from a large, urban, pediatric tertiary care center to address the health and psychosocial-related concerns of AYA living with chronic illness. We highlight valuable lessons from the capacity-building process in terms of increasing the ability of providers in a major pediatric healthcare center to provide developmentally appropriate care for AYA living with chronic illness. Finally, based on the results of our study, we provide recommendations on how to employ such a process in similar pediatric hospital settings.
