Published: January 2021

Lithium-based molten salts have attracted significant attention due to their applications in energy storage, advanced fission reactors and fusion devices. Lithium fluorides and particularly 66.6%LiF-33.3¾F2 (Flibe) are of considerable interest in nuclear systems, as they show an excellent combination of desirable heat-transfer and neutron-absorption characteristics. For nuclear salts, the range of possible local structures, compositions, and thermodynamic conditions presents significant challenges in atomistic modeling. In this work, we demonstrate that atom-centered neural network interatomic potentials (NNIP) provide a fast and accurate method for performing molecular dynamics of molten salts. For LiF, these potentials are able to accurately model dimer interactions, crystalline solids under deformation, semi-crystalline LiF near the melting point and liquid LiF at high temperatures. For Flibe, NNIPs accurately predicts the structures and dynamics at normal operating conditions, high temperature-pressure conditions, and in the crystalline solid phase. Furthermore, we show that NNIP-based molecular dynamics of molten salts are scalable to reach long timescales (e.g., nanosecond) and large system sizes (e.g., 105 atoms), while maintaining ab initio accuracy and providing more than three orders of magnitude of computational speedup for calculating structure and transport properties.

Protective coatings applied to cathodes help to overcome interface stability issues and extend the cycle life of Li-ion batteries. However, within 3D cathode composites it is difficult to isolate the effect of the coating because of the additives and non-ideal interfaces. In this study we investigate niobium oxide (NbOx) as cathode coating in a thin-film model system, which provides simple access to the cathode-coating-electrolyte interface. The conformal NbOx coating was applied by atomic layer deposition (ALD) onto thin-film LiCoO2 cathodes. The cathode/coating stacks were annealed to lithiate the NbOx and ensure sufficient ionic conductivity. A range of different coating thicknesses were investigated to improve the electrochemical cycling with respect to the uncoated cathode. At a NbOx thickness of 30 nm, the cells retained 80% of the initial capacity after 493 cycles at 10 C, more than doubling the cycle life of the uncoated cathode film. At the same thickness, the coating also showed a positive impact on the rate performance of the cathode: 47% of the initial capacity was accessible even at ultrahigh charge-discharge rates of 100 C. Using impedance spectroscopy measurements, we found that the enhanced performance is due to suppressed interfacial resistance growth during cycling. Elemental analysis using TOF-SIMS and XPS further revealed a bulk and surface contribution of the NbOx coating. These results show that in situ lithiated ALD NbOx can significantly improve the performance of layered oxide cathodes by enhancing interfacial charge transfer and inhibiting surface degradation of the cathode, resulting in better rate performance and cycle life.

We present an electrochemical advanced oxidation process (eAOP) reactor employing expanded graphite, potassium iodide (KI), and electrical current, which demonstrates an exceptionally high rate of inactivation of E. coli (6log reduction in viable cells) at low current density 0.6 mA/cm^2), with low contact time (5 minutes) and low concentration of KI (10 ppm). Operando X-ray fluorescence mapping is used to show the distribution of iodine species in the reactor, and operando X-ray absorption spectroscopy in the anodic chamber reveals iodine species with higher effective oxidation state than periodate. Operando electrochemical measurements confirm the conditions in the anodic chambers are favourable for the creation of highly oxidized iodine products. The killing efficiency of this new eAOP reactor far exceeds that expected from either traditional iodine-based electrochemical water treatment or advanced oxidation systems alone, a phenomenon that may be associated with the production of highly oxidized iodine species reported here.

Published: January 2021

Dinitrogen pentoxide (N2O5) is an important intermediate in the atmospheric chemistry of nitrogen oxides. Although there has been much research, the processes that govern the physical interactions between N2O5 and water are still not fully understood at a molecular level. Gaining quantitative insight from computer simulations requires going beyond the accuracy of classical force fields, while accessing length scales and time scales that are out of reach for high-level quantum chemical approaches. To this end we present the development of MB-nrg many-body potential energy functions for simulations of N2O5 in water. This MB-nrg model is based on electronic structure calculations at the coupled cluster level of theory and is compatible with the successful MB-pol model for water. It provides a physically correct description of long-range many-body interactions in combination with an explicit representation of up to three-body short-range interactions in terms of multidimensional permutationally invariant polynomials. In order to further investigate the importance of the underlying interactions in the model, a TTM-nrg model was also devised. TTM- nrg is a more simplistic representation that contains only two-body short-range interactions represented through Born-Mayer functions. In this work an active learning approach was employed to efficiently build representative training sets of monomer, dimer and trimer structures, and benchmarks are presented to determine the accuracy of our new models in comparison to a range of density functional theory methods. By assessing binding curves, distortion energies of N2O5, and interaction energies in clusters of N2O5 and water, we evaluate the importance of two-body and three-body short-range potentials. The results demonstrate that our MB-nrg model has high accuracy with respect to the coupled cluster reference, outperforms current density functional theory models, and thus enables highly accurate simulations of N2O5 in aqueous environments.

Published: January 2021

Single amino acid based self-assembled structures have gained a lot of interest recently owing to their pathological significance in metabolite disorders. There is plethora of significant research work which illustrate amyloid like characteristics of assemblies formed by aggregation of single amino acids like Phenylalanine, Tyrosine, Tryptophan, Cysteine and Methionine and its implications in pathophysiology of single amino acid metabolic disorders like phenylketonuria, tyrosinemia, hypertryptophanemia, cystinuria and hypermethioninemia respectively. Hence, studying aggregation behaviour of single amino acids is very crucial to assess the underlying molecular mechanism behind metabolic disorders. In this manuscript we report for the very first time the aggregation properties of non-aromatic single amino acids Hydroxy-proline and Proline. The morphologies of these were studied extensively by Optical microscopy (OM), ThT binding fluorescence microscopy, Scanning Electron Microscopy (SEM) and Atomic force microscopy (AFM). It can be assessed that these amino acids form globular structures at lower concentrations and gradually changes to tape like structures on increasing the concentration as assessed by AFM. ThT and CR binding assay reveal the aggregates do have amyloid like characteristics. Further MTT assays on SHSY5Y neural cell lines reveal cytotoxicity and the aggregates caused significant cell death in dose dependent manner. These results have important implications in understanding the pathophysiology of single amino acid disorders like Hyperprolinemia and Hydroxyprolinemia in association with amyloid diseases. The symptoms of these diseases are also accompanied by extensive neurological problems like intellectual disability, seizures and psychiatric problems which further evince amyloid like etiology for these rare in-born errors of metabolism.
Persistent Homology Metrics Reveal Quantum Fluctuations and Reactive Atoms in Path Integral Dynamics

Published: January 2021

Nuclear quantum effects (NQEs) are known to impact a number of features associated with chemical reactivity and physicochemical properties, particularly for light atoms and at low temperatures. In the imaginary time path integral formalism, each atom is mapped onto a “ring polymer” whose spread is related to the quantum mechanical uncertainty in the particle’s position i.e. its thermal wavelength. A number of metrics have previously been used to investigate and characterize this spread and explain effects arising from quantum delocalization, zero-point energy, and tunnelling. Many of these shape metrics consider just the instantaneous structure of the ring polymers. However, given the significant interest in methods such as centroid molecular dynamics and ring polymer molecular dynamics that link the molecular dynamics of these ring polymers to real time properties, there exists significant opportunity to exploit metrics that also allow for the study of the fluctuations of the atom delocalization in time. Here we consider the ring polymer delocalization from the perspective of computational topology, specifically persistent homology, which describes the 3-dimensional arrangement of point cloud data (i.e. atomic positions). We employ the Betti sequence probability distribution to define the ensemble of shapes adopted by the ring polymer. The Wasserstein distances of Betti sequences adjacent in time are used to characterize fluctuations in shape, where the Fourier transform and associated principal components provides added information differentiating atoms with different NQEs based on their dynamic properties. We demonstrate this methodology on two representative systems, a glassy system consisting of two atom types with dramatically different de Broglie thermal wavelengths, and ab initio molecular dynamics simulation of an aqueous 4 M HCl solution where the H-atoms are differentiated based on their participation in proton transfer reactions. Keywords: path integral molecular dynamics, persistent homology, quantum delocalization, proton transfer, Wasserstein distances.

CASE STUDY: THE DIDACTIC MODEL OF SOCIO-COGNITIVE THEORY OF LEARNING IN THE TEACHING OF ENGLISH AS A FOREIGN LANGUAGE. TEACHING STATE AND ACTIVITY VERBS
Authors: Pappas Georgios
Published: January 2021

Language has generally been characterized as a tool of communication between people, the mean by which man expresses his feelings and thoughts. It has been the subject of research from various angles and methodological standards that largely reflect the variety of dimensions from which it can be studied but also the prevailing analysis trends. Language is also seen as a social process, as a way of creating interpersonal relationships and expressing emotions. Therefore, integrated language teaching takes into account the social character of the language and relies on it. The linguistic and cultural diversity within the European Union has created new demands for multilingual European citizens. To meet the new requirements, it is necessary, educational strategies to be designed by those who actively involved in foreign language education in various countries in a new context, which will ensure the “productivity” of learning foreign languages in the implementation of foreign language education. There is an urgent need to promote the process of communicative teaching, so that the student who learns the specific foreign language transmits his own concepts, in the cases, interacting and trying to adapt to the common knowledge and even the linguistic ability of a person that this language is his/her mother tongue. The approach to the service of the communicative type of teaching emphasizes the communicative function of the language and tries to create in the students the opportunities for functional use of the language code, similar to those they will encounter outside the classroom.
Students need to connect with each other to build friendly relationships within the classroom that becomes a student community. This effort also includes this paper, which introduces the model of socio-cognitive learning theory in the context of the communicative approach to the teaching and learning of foreign languages.
THE PREPARATION OF FUTURE TEACHERS: MODERN APPROACHES TO LEARNING
Authors: Khalymon Iryna , Shevchenko Svitlana
Published: January 2021

The article is devoted to the issue of approaches to learning used by prospective teachers. The key difference between two main approaches to learning — deep and surface — lies in the intention or absence of intention to understand the material. Deep approach to learning is likely to result in a high level of understanding and better learning outcomes while surface approach leads to ineffective learning. Understanding students’ approaches to learning helps adjust teaching strategies for more effective learning. The purpose of the article is to identify the approaches to learning used by prospective teachers and consider the implications for teacher trainers. The article reports findings of a survey study into the approaches to learning used by prospective teachers of the Ukrainian language and literature mastering English as a specialism at a Ukrainian university. The main research tool was a questionnaire consisting of twenty statements. Ten statements concerning deep approach include such aspects as deep approach per se, relating ideas, use of evidence, intrinsic motivation. The other ten statements relate to surface approach and include such subscales as surface approach proper, syllabus boundness, fear of failure, extrinsic motivation.
The respondents were asked to express how much they agreed with the statements using Likert scale. The data were analysed to find out mean scores and standard deviation. The findings demonstrate that students employ both approaches almost equally intensely: the mean scores of the Deep Learning Approach and the Surface Learning Approach scales are 3.64 and 3.34 correspondingly. However, according to the evaluation criteria the figures fall into different categories: deep approach has a high level of prevalence while surface approach has a moderate one. Basing on the obtained results, the authors suggest that teacher trainers should pay more attention to promoting deep learning approach through applying effective instructional strategies which improve the quality of learning; fostering students’ personal interest in learning; changing the focus of the assessment system from reproducing to understanding

Background: Little research has been conducted on the estimate formulas for waist circumference using body mass index and limb circumferences in hospitalized older adults. Thus, we conducted the present study to develop estimate formulas of waist circumference using body mass index and limb circumferences in hospitalized older adults. Methods: Forty hospitalized older patients were recruited in this cross-sectional study. We measured waist circumference, body mass index, upper arm circumference, forearm circumference, thigh circumference, and calf circumference. The estimate formulas for waist circumference were developed using simple and multiple regression analysis. Results: Simple regression analysis indicated that body mass index, upper arm circumference, forearm circumference, thigh circumference, and calf circumference were independent explanators for waist circumference (p < 0.05 for all). In addition, body mass index, upper arm circumference, and forearm circumference but not thigh circumference and calf circumference were extracted as independent explanators for waist circumference in multiple regression analysis (p < 0.05). We were able to develop the estimate formulas using body mass index, upper arm circumference, forearm circumference, thigh circumference, and calf circumference. Conclusion: The results suggest that the estimate formulas for waist circumference may provide an opportunity to easily evaluate waist circumference, even in hospitalized older adults with kyphosis posture. However, future studies should be conducted to develop the estimate formulas for waist circumference with a lower error value.
SIMULATION OF PSO BASED APPROACH FOR CMOL CELL ASSIGNMENT PROBLEM
Authors: Shrivastava Prateek , Deshmukh Khemraj
Published: January 2021

Particle swarm optimization (PSO) approach is used over genetic algorithms (GAS) to solve many of the same kinds of problems. This optimization technique does not suffer, however, from some of GA’s difficulties; interaction in the group enhances rather than detracts from progress toward the solution. Further, a particle swarm system has memory, which the genetic algorithm does not have. In particle swarm optimization, individuals who fly past optima are tugged to return toward them; knowledge of good solutions is retained by all particles. The genetic algorithm works with the concept of chromosomes having gene where each gene act as a block of one solution. This is totally based on the solution which is followed by crossover and then mutation and finally reaches to fitness. The best fitness will be considered as a result and implemented in the practical area. Due to some drawbacks and problems exist in the genetic algorithm implemented, scientists moved to the other algorithm technique which is apparently based on the flock of birds moving to the target. This effectively overcome the shortcomings of GA and provides better fitness solutions to implement in the circuit.

Los sistemas definidos estuvieron representados por los suelos de vega (márgenes de los ríos), potreros (pastizales), terrenos intermedios para el cultivo de maíz y en sucesión secundaria (acahual). La metodología se fundamentó en la germinación directa, para lo cual se obtuvieron muestras compuestas de suelo a tres profundidades (0-10, 10-20 y 20-30 cm), las cuales se colocaron en charolas de 50 x 30 x 10 cm, ubicándolas en invernadero para evitar su contaminación, proporcionándoles riegos regulares. Cada sistema estuvo representado por tres réplicas, 36 unidades de muestreo totales. Las variables evaluadas fueron número de especies e individuos emergidos, densidad y dominancia relativa, diversidad florística y similitud de comunidades y efectos alelopáticos de las arvenses dominantes. Los resultados indican que los sistemas manejados intensivamente para actividades agrícolas, específicamente terrenos de vega e intermedios para el monocultivo de maíz, presentaron bancos de semillas más dinámicos, lo cual sucede en los primeros 10 cm de profundidad. Las especies de arvenses dominantes de los bancos evaluados fueron Cyperus rotundus L. y Melampodium divaricatum Rich. La diversidad florística determinó índices similares entre los sistemas y profundidades. La mayor similitud entre comunidades se presentó en los agroecosistemas manejados con el cultivo maíz. No se determinaron efectos alelopáticos de las especies dominantes sobre la germinación y crecimiento de los cultivos representativos de la región.

The recent history of urban development in Italy largely stems from a policy – here
intended as a set of actions and strategies of administrators, entrepreneurs and
experts – which has been incapable of planning transformations and, therefore,
adopting a shared and far-sighted approach to development.
The urban regeneration of metropolitan areas and their consequent demographic
and economic development (70% of the population and 80% of GDP are concentrated
in these areas) have often penalised internal areas such as the Alps and
Apennines.
Some peculiar experiences, including the regeneration of the village of Ostana (Cuneo),
the project carried out in Contrada Bricconi (Bergamo), or even the activities
of the association Dolomiti Contemporanee (Belluno) – just to mention a few interesting
cases in the Italian Alps, – show that the understanding of and care for
a unique territory are the pillars on which any informed political, administrative, architectural
or territorial project should be based. This approach is all the more important
in the framework of those events envisaging the construction of large infrastructures
(such as the 2026 Winter Olympics in Milan-Cortina). After these events,
such infrastructures are often abandoned because they are useless for the territory,
economically unsustainable in the long-term, and not shared with the local
community.
In this perspective, the work of the association Architetti Arco Alpino (Alpine Arc Architects),
whose activities range from architecture awards to photographic surveys,
conferences and publications, aims to understand the complexity of mountain areas
and to promote architectural quality. In this framework, they have successfully
shown how the problems are often the same regardless of geographical and cultural
distances.
The solution to these problems is to be found primarily in the act of listening to the
places and history of the local population; whether in the Alps or elsewhere, every
good project based on a contemporary and conscious approach starts from there.
Progettare con il Genius loci
Authors: Baserga Nicola
Published: January 2021

"The essay describes three design projects which aim to interact specifically with
the Alpine context, in Switzerland, in contrast to the undifferentiated and non-specific
nature of architecture in the age of globalisation.
The Jugendwohnheim Mattini project in Brig enhances the surrounding rural landscape
by repurposing a castle as a youth home for the housing and education of
adolescents in need. The small baroque castle has undergone conservative renovation;
the former barn on its side now houses teaching spaces, and a new building
on the other side has been added to provide both common rooms and private bedrooms.
The surrounding shared outdoor area is ideal for both leisure and educational
activities: they provide an opportunity for socialisation and reintegration through
work and care of the land, and through the enjoyment of its products, which translate
into regeneration and self-care.
The project for a new elderly home in Giornico interacts with the natural landscape
of the Leventina Valley, which is narrowed by steep slopes and crossed by the river
Ticino. The characteristic reference points used by the designers for the development
of the final projects of the elderly home are the Romanesque church of St.
Nicholas, marked by precise and rigorous stereometric volumes, and the La Congiunta
museum, designed by architect Peter Märkli.
The square layout of the elderly home frees up space on the sides and creates a dialogue
with the surrounding environment. It extends in height, with a portico on the
ground floor and a terrace on the top floor covering the entire perimeter of the building.
Inside, the common rooms recall the density of villages, while the bedrooms
offer domestic intimacy. Pathways and panoramic viewpoints overlook the surrounding
landscape, with its natural and cultural values, representing the scenery of
everyday life and the memory of the elderly.
Thanks to the restoration of the Motto bridge over river Brenno, the infrastructure
reconnects to the landscape, linking the village church to the oratory of the cemetery.
The bridge re-establishes a continuity between anthropic artefacts, historical
values, and the river landscape."
The Welfare State as a Practice of Compromise: European Models
Authors: Kanarsh Grigory Y.
Published: January 2021

The article analyzes the features of three main models of the welfare state: German, Northern European, and Anglo-Saxon. The author turns to the analysis of these models, first, because the problem of the welfare state in the world is again coming to the fore, and secondly, because social development in the most developed countries, in the author’s opinion, in the future will be largely determined by the values and behavioral models that are embedded in the three main versions of the social state in Europe. From the author’s point of view, the key features of the European social model, which combines these three versions, are respect for rights and human dignity, the ideas of equality and solidarity, the ideas of social and political compromise, and the choice of an evolutionary path of development. According to the author, these features are the main difference between the European model and what characterizes the political culture of Russia with its maximalism and tendency to extremes. The author believes that the social experience of Europe is something that needs to be addressed today in Russian conditions and that can be extremely valuable for us. At the same time, as shown in the article, the welfare state in Europe has important country features. The German model is characterized by an emphasis on maintaining the socio-economic status of the individual – this is a conservative model. The Northern European model is based on the principles of universal equality and universalism – it is a social-democratic model. And the Anglo-Saxon model, based on the low role of the state, on the great importance of civil society, is a liberal model. Nevertheless, despite significant differences, as shown in the article, all these models are characterized by the desire to implement compromise principles, to find a “Golden mean,” which makes them highly effective.
Language Teacher Assessment Literacy: A Current Review
Authors: Nurdiana Nurdiana Nurdiana
Published: January 2021

HHalf of the language teachers’ time is spent on assessing students’ performance. Therefore, they should be literate to language assessment in terms of how to make a good test or knowing which method appropriate to assess their students’ learning. Without having assessment literacy, they may not be able to help their students achieve the best results of their performance. For this reason, the present study attempts to examine language teacher assessment literacy and how it has been measured. Besides, suggestions and recommendations for language teachers regarding assessment literacy are discussed in this study. A literature review was employed to conduct this research. Findings suggest that language teachers need more training on language assessment due to their lack of knowledge of language assessment. Although some of them are assessment literate, they do not practice the knowledge in their classroom. This implies that the training they need could be on how to select appropriate assessments for their students, how to design a test,  alternative assessments, and test specifications.
