Published: October 2020

The article is devoted to the problem of language knowledge formation and speech skills of elementary classroom on Ukrainian language lessons. In the exercises proposed for this, the language assignments used as a means of forming and improving the structure of opinion of the elementary classroomand speech tasks which provide communication of the language and speech, speech and thinking are highlighted, constant training of students in statement thoughts. The authors adapted the local history material for the better perception of elementary classroomand used the texts of the regional character as a means of personal interest of the material being studied. The article proved expediency of active involvement of pupils to cognitive and speech activity as an important precondition for consolidation of their active life position, comprehension of the ideals good, beauty and love to the native land. In addition to the theoretical substantiation of the need to form elementary school linguistic and speech competence, the authors of the article cover the ways of developed complex tasks to exercises and results of conducted research. The authors suggest that quality of education process is greatly improved by fostering special creative environment. Conditions of creative environment are: 1) combined technology of content learning with integrated lesson materials to highlight cross-curriculum connections to achieve comprehensive results in elementary education; 2) deliberate assignment selection to develop basic academic competencies, critical thinking, individual interests and abilities to process and summarize information, and to spark and to maintain student interest in learning; 3) use of local history materials to study Ukrainian language to form intrinsic motivation, initiative and self-reliance in the education process; 4) innovative methods and techniques to encourage practical experiential learning rooted in local history. The authors argue that creative environment plays a significant role in activating of student creative potential. Research results may be used as input for further studies on the topic. The authors encourage future research in application of advanced methodologies and techniques for development of verbal and communication competencies while mastering Ukrainian language in elementary classroom. Aids and materials developed in this study may be used by elementary educators for developing integrated classroom curriculum and planning educational events for development of verbal, communication and local history competencies.
ANTITHESIS AS A SEMANTIC FEATURE OF JOSEPH’S STYLE IN THE TRANSFORMATION OF CONCEPTUAL UNITS OF TRAGEDY AND BEAUTY
Authors: Chernysh Lilia , Koshlan Maria
Published: October 2020

The article examines the antithesis as one of the stylistic figures of Leviathan’s artistic work, which is a crucial element of conceptual discourse and allows us to speak about the isolation of Joseph Roth’s idiostyle. The antithesis presented by the author in the work of Leviathan is not just a comparison of two words, phrases, sentences, etc., but comparison and even a juxtaposition of the two worlds – the real and the dreamed one. Through this antithesis, the author managed to convey the tragedy of the dreamed world through beauty, through descriptions of the main character, because of the contrast between the beautiful, the ugly, the weak, the strong, the pale, the bright, which gives the work a specific colour and can be considered an exceptional kind of antithesis. Using concepts such as comparison and antithesis, we can say that a comparison is a litmus unit. It defines the essence and truth of a phenomenon, and if we speak of a language that also reflects the spiritual side of native speakers, namely: mentality, value system, morality, then we are talking about style and the author in whose language we discover being. After all, antithesis opens many ways for individual style, because it has different stylistic functions and contributes to the immersion in the essence of the phenomenon that we know. In this context, it is possible to distinguish such kind of antithesis as stylistic antithesis, which not only isolates the idiostyle of the author but is also a critical linguistic and stylistic unit of the whole conceptual discourse.
TRANSFORMATIONS OF SET PHRASES WITH THE PROPER NAME COMPONENT IN THE MODERN UKRAINIAN MEDIA DISCOURSE
Authors: Arkhanhelska Alla
Published: October 2020

The paper deals with set phrases (phraseologisms, set comparisons, and proverbs) with the proper name component of the precedent and unprecedent nature in texts of modern Ukrainian media. The paper is focused both on the semantic and structural semantic transformations of set phrases with the proper name component and on creating the transformed phrases on the basis of the model. The paper traces the rate of transformations of phraseological units and proverbs with the proper name component of the precedent and unprecedent nature in the modern Ukrainian media discourse, investigates the types of transformations (semantic and structural-semantic), outlines the trends of transforming set phrases based both on Ukrainian and borrowed proper names, and describes the creation of transformed units on the basis of the model. The study is based on the material of biblical names, ancient names, mythological anthroponyms, names of historical persons and figures in modern politics as well as connotative onyms that are a component of the Ukrainian linguoculture, which were all investigated based on Ukrainian printed and electronic publications, Internet forums and blogs of the beginning of the 21st century.
Hydrophobic Biomimetic Nanoparticles drives Size-dependent Remodelling in Asymmetric Bilayers
Authors: Noh Sang , Notman Rebecca
Published: October 2020

The interactions between heterogeneous components in a biomimetic bilayer can control its physical properties such as its rigidity, local and bulk curvature and propensity towards phenomena such as membrane fission and fusion. In particular, nanoparticles (NPs) have been subjects of intense interest due to their similar scale to the bilayer width and its ability to affect local membrane structure. Generally, it is understood that hydrophobic components are energetically favoured to adsorb within the hydrophobic interior of a biomimetic bilayer. However, how such NPs interact in the presence of heterogeneous aggregates in the bilayer has been the subject of much debate. To better understand the effects of the integration of nanoscale components on heterogeneous mixed bilayer, we have simulated a series of generic hydrophobic NPs interacting with a phase-separating two-component surfactant bilayer. We find that the hydrophobic NP tends to aggregate at the phase interface, acting as a line tension relaxant i.e. a lineactant on the phase separated interface, which results in a variety of demixing behavior. We demonstrate that depending on the size of the NP, the localized softening of surfactants and the formation of a mixing gradient of surfactants can drive the a cap/bud formation around the NP, as well as the formation of a NP-micelle structure

We report the successful electrochemical intercalation of F-ions into a densely packed perovskite oxide from a liquid electrolyte at room temperature. Using galvanostatic oxidation and electrochemical impedance spectroscopy coupled with operando X-ray diffraction, we show that roughly 0.5 equivalents of F-ions can be inserted onto the vacant A-site of the perovskite ReO3. Density functional theory calculations indicate that the intercalated phase is thermodynamically unfavorable compared to other less densely packed polymorphs of ReO3F. Pairing X-ray spectroscopy, neutron total scattering measurements, and magic-angle spinning 19F NMR confirms a rapid decomposition of the product on removal from the cell but nevertheless, these results clearly demonstrate that small anions like fluoride can be intercalated into solids as readily as alkali cations at room temperature, which opens new opportunities to electrochemically fluorinate many new materials.

Published: October 2020

Conducting polymers are versatile semiconductors whose applications cover a wide range of devices. Their versatility is due, in addition to other factors, to properties that can be easily modulated according to the intended application. It is therefore important to study and map the electronic structure of these materials to allow for a better correlation between structure and properties. Electrochemical scanning tunnelling spectroscopy (EC-STS) can be a powerful tool to characterize the electronic structure of the semiconductor electrolyte interface. In this work we have used image-based EC-STS (IB-EC-STS) to describe quantitatively the band structure of an electrochemically deposited polypyrrole (PPy) film. IB-EC-STS located the band edge of the polymer’s valence band (VB) at 0.95 V vs. RHE (-5.33 eV in the absolute potential scale) and the intragap polaron states formed when the polymer is oxidised (doped) at 0.46 V vs. RHE (-4.84 eV in the absolute potential scale). The IB-EC-STS data were cross checked with electrochemical impedance spectroscopy (EIS) and Mott-Schottky analysis of the interfacial capacitance. The DOS spectrum obtained from EIS data is consistent with the STS-deduced location of the VB and the polarons.

Na-ion batteries are promising devices for smart grids and electric vehicles due to cost effectiveness arising from the overall abundance of sodium (Na) and its even geographical distribution. Among other factors, the energy density of Na-ion batteries is limited by the positive electrode chemistry. NaSICON-based positive electrode materials are known for their wide range of electrochemical potentials,[1],[2],[3] high ionic conductivity, and most importantly their structural and thermal stabilities. Using first- principles calculations, we chart the chemical space of 3d transition metal-based NaSICON phosphates of formula NaxMM’(PO4)3 (with M and M’= Ti, V, Cr, Mn, Fe, Co and Ni), to analyze their thermodynamic stabilities and the intercalation voltages for Na+ ions. Specifically, we computed the Na insertion voltages and related properties of 28 distinct NaSICON compositions. We investigated the thermodynamic stability of Na-intercalation in previously unreported NaxMn2(PO4)3 and NaxVCo(PO4)3. The calculated quaternary phase diagrams of the Na-P-O-Co and Na-P-O-Ni chemical systems explain the origin of the suspected instability of Ni and Co-based NaSICON compositions. From our analysis, we are also able to rationalize anomalies in previously reported experimental data in this diverse and important chemical space.
Forward Reaction Prediction as Reverse Verification: A Novel Approach to Retrosynthesis
Authors: Wang Ling , Zhang Chengyun , Bai Renren , Li Jianjun , Duan Hongliang
Published: October 2020

Pupils' intuitive knowledge can lead them to verify multiplication by means of division. Based on this analogy, this study introduces the basic reverse verification concept to verify retrosynthesis through forward reaction. In this work, we present a "combined" model approach for retrosynthetic reaction prediction, where the first model is applied to retrosynthesis, and the second model, which is a "verified" model, is applied to the forward reaction prediction to verify the top-n reactants predicted by the retrosynthetic model. Using a "combined" model borrowed from human language translation, sequence-to-sequence (seq2seq) + transformer models, we improve the top-1 accuracy of retrosynthetic prediction by 4.3% (37.4% vs 41.7%). The application of the similarity + seq2seq models increases the top-1 accuracy by 4.6% (52.9% vs 57.5%). In this way, we can not only improve the accuracy but also automate the evaluation of the synthetic route.

Published: October 2020

A user-friendly approach to sidestep the venerable Grignard addition to unactivated ketones to access tertiary alcohols by reversing the polarity of the disconnection. In this work a ketone instead acts as a nucleophile when adding to simple unactivated olefins to accomplish the same overall transformation. The scope of this coupling is broad as enabled using an electrochemical approach and the reaction is scalable, chemoselective, and requires no precaution to exclude air or water. Multiple applications demonstrate the simplifying nature of the reaction on multi-step synthesis and mechanistic studies point to an intuitive mechanism reminiscent of other chemical reductants such as SmI2 (which cannot accomplish the same reaction).
Effect of Fluoroethylene Carbonate Additive on the Initial Formation of Solid Electrolyte Interphase on Oxygen Functionalized Graphitic Anode in Lithium Ion Batteries
Authors: Intan Nadia , Pfaendtner Jim
Published: October 2020

The formation of a solid electrolyte interphase (SEI) at the electrode/electrolyte interface substantially affects the stability and lifetime of lithium-ion batteries (LIBs). One of the methods to improve the lifetime of LIBs is by the inclusion of additive molecules to stabilize the SEI. To understand the effect of additive molecules on the initial stage of SEI formation, we compare the decomposition and oligomerization reactions of a fluoroethylene carbonate (FEC) additive on a range of oxygen functionalized graphitic anode to those of an ethylene carbonate (EC) organic electrolyte. A series of density functional theory (DFT) calculations augmented by ab-initio molecular dynamics (AIMD) simulations reveal that EC decomposition on an oxygen functionalized graphitic (1120) edge facet through an SN2 mechanism is spontaneous, even in an uncharged cell. Decomposition of EC through an SN2 reaction pathway results in alkoxide species regeneration which is responsible for continual oligomerization along the graphitic surface. In contrast, FEC prefers to decompose through an SN1 pathway, which does not promote alkoxide regeneration. The ability of FEC as an additive to suppress alkoxide regeneration results in a smaller and thinner SEI layer that is more flexible towards lithium intercalation during the charging/discharging process. In addition, the presence of different oxygen functional groups at the surface of graphite dictates the oligomerization products and LiF formation in the SEI.

The central promise of nanoparticle-based materials is that cooperative properties may emerge, when individual quantum dots are positioned on a periodic lattice. Yet, there are only few papers in literature reporting about such effects. Nevertheless, it is clear that the symmetry of the superlattice is decisive for the desired emergent phenomena. An interesting question is, how the symmetry of the initial monodisperse nanoparticles affects the structure of the colloidal crystal during self-assembly processes. For instance, particles with hexagonal cross-section show self-organization which is very similar to spherical colloids. Like-wise one would also expect that trigonal nanoparticles behave similar. Unfortunately, it is very hard to obtain monodisperse semiconductur colloids with trigonal shape, because this requires a symmetry break during morphogenesis of the nanocrystal. While such a symmetry-break is known in literature for structures attached to a solid substrate, it is shown here, colloidal synthesis of trigonal ZnO nanorods is successful, and the mechanism is elucidated by experimental and theoretical methods. 2D-superlattices formed by such particles with trigonal cross-section were compared to hexagonal analogues. It was found, there are distinct differences, which result in important differences in properties such as the formation of voids and also in optical properties.
Thermodynamic Decomposition of Solvation Free Energies with Particle Mesh Ewald and Long-Range Lennard-Jones Interactions in Grid Inhomogeneous Solvation Theory

Published: October 2020

Grid Inhomogeneous Solvation Theory (GIST) maps out solvation thermodynamic properties on a fine meshed grid and provides a statistical mechanical formalism for thermodynamic end-state calculations. However, differences in how long-range non-bonded interactions are calculated in molecular dynamics engines and in the current implementation of GIST have prevented precise comparisons between free energies estimated using GIST and those from other free energy methods such as thermodynamic integration (TI). Here, we address this by presenting PME-GIST, a formalism by which particle mesh Ewald (PME) based electrostatic energies and long-range Lennard-Jones (LJ) energies are decomposed and assigned to individual atoms and the corresponding voxels they occupy in a manner consistent with the GIST approach. PME-GIST yields potential energy calculations that are precisely consistent with modern simulation engines and performs these calculations at a dramatically faster speed than prior implementations. Here, we apply PME-GIST end-states analyses to 32 small molecules whose solvation free energies are close to evenly distributed from 2 kcal/mol to -17 kcal/mol and obtain solvation energies consistent with TI calculations (R2 = 0.99, mean unsigned difference 0.8 kcal/mol). We also estimate the entropy contribution from the 2nd and higher order entropy terms that are truncated in GIST by the differences between entropies calculated in TI and GIST. With a simple correction for the high order entropy terms, PME-GIST obtains solvation free energies that are highly consistent with TI calculations (R2 = 0.99, mean unsigned difference = 0.4 kcal/mol) and experimental results (R2 = 0.88, mean unsigned difference = 1.4 kcal/mol). The precision of PME-GIST also enables us to show that the solvation free energy of small hydrophobic and hydrophilic molecules can be largely understood based on perturbations of the solvent in a region extending a few solvation shells from the solute. We have integrated PME-GIST into the open-source molecular dynamics analysis software CPPTRAJ.

Published: October 2020

Ultralong organic room-temperature phosphorescence (RTP) materials have attracted great attention recently due to its diverse application potentials. Several ultralong organic RTP materials mimicking the host-guest architecture of inorganic systems have been exploited successfully. However, complicated synthesis and high expenditure are still inevitable in these cases. Herein, we develop a series of novel host–guest organic phosphore systems, in which all chromophores are electron-rich, commercially available and halogen atom free. The maximum phosphorescence efficiency and the longest lifetime reach at 23.6% and 362 ms, respectively. Most importantly, experimental results and theoretical calculation indicate that the host molecules not only play a vital role in providing a rigid environment to suppress non-radiative decay of the guest, but also show a synergistic effect to the guest through Förster energy transfer (FERT). The commercial availability, facile preparation and unique properties also make these new host-guest materials an excellent candidate for anti-counterfeiting devices.

Published: October 2020

Electrochemically-mediated Photoredox Catalysis emerged as a powerful synthetic technique in recent years, overcoming fundamental limitations of electrochemistry and photoredox catalysis in the single electron transfer activation of small organic molecules. However, the mechanism of how photoexcited radical ion species with ultrashort (picosecond-order) lifetimes could ever undergo productive photochemistry has eluded synthetic chemists. We report tri(para-substituted)biarylamines as a tunable class of electroactivated photocatalysts that become superoxidants in their photoexcited states, even able to oxidize molecules (such as dichlorobenzene and trifluorotoluene) beyond the solvent window limits of cyclic voltammetry. Furthermore, we demonstrate that precomplexation not only permits the excited state photochemistry of tris(para-substituted)biarylaminium cations, but enables and rationalizes the surprising photochemistry of their higher-order doublet (Dn) excited states.

Published: October 2020

Enzymes are biocatalysts responsible for driving all biochemical reactions in the cells. The enzymes determine the physiology of a cell and together regulate the growth and proliferation of cells in response to various environmental signals. The ability of cells to adapt and respond to environmental conditions can be utilized for industrial applications. Hydrolases and oxidoreductases are the most common classes of enzymes used in various industries such as pharmaceutical, food and beverages, bioremediation and biofuels, among others. Oxidoreductases are the EC1 class enzymes that catalyze the biological oxidation and reduction reactions. They transfer electrons from one molecule (reductant that donates electron) to other molecules (oxidants those accept electron). Usually, the enzymes of this class are NAD+ (Nicotinamide Adenine Dinucleotide) or NADP (Nicotinamide Adenine Dinucleotide Phosphate)-dependent. The oxidoreductases are a diverse class of enzymes responsible for catalyzing highly stereo selective and regioselective reactions, because of which they are the enzymes of choice for synthesis of optically-active compounds. Alcohol dehydrogenase (ADH) is one of the most studied oxidoreductases. Generally, ADHs have narrow specificity towards their substrates. Here we are looking for ADH having high/ broad specificity towards the substrate. This review discusses the enzyme oxidoreductase, synthetic transformation with oxidoreductase and application of oxidoreductase in bioremediation.

PLASMA RICO EN PLAQUETAS EN LA REGENERACIÓN ÓSEA DE ALVÉOLOS DENTARIOS POST-EXODONCIA
Authors: Alves Dos Santos Elias
Published: October 2020

Con el objetivo de analizar el empleo del plasma rico en plaquetas en la regeneración ósea de alvéolos dentarios post-exodoncia se realizó una revisión bibliográfica acerca del PRP, según la evidencia científica disponible en la literatura. La búsqueda de información se hizo en las bases de datos de Medline/PubMed, Wiley Online Library, OVID, EBSCO, ScienceDirect y Nature.com Se encontró que por ser fruto de una preparación autógena realizada momentos antes del procedimiento quirúrgico, el PRP reduce el riesgo de transmisión de enfermedades infectocontagiosas cuando se compara a otros productos. Se concluye que el PRP representa un avance en las técnicas de injertos óseos, pues este ofrece acceso a los factores de crecimiento con una simple y disponible tecnología; estos factores de crecimiento son autólogos, no tóxicos y no inmunogénicos; mejora y acelera los caminos normales de regeneración ósea.
Extracting image features for classification by two-tier genetic programming
Authors: Al-Sahaf Harith , Song A , Neshatian K , Zhang Mengjie
Published: October 2020

Image classification is a complex but important task especially in the areas of machine vision and image analysis such as remote sensing and face recognition. One of the challenges in image classification is finding an optimal set of features for a particular task because the choice of features has direct impact on the classification performance. However the goodness of a feature is highly problem dependent and often domain knowledge is required. To address these issues we introduce a Genetic Programming (GP) based image classification method, Two-Tier GP, which directly operates on raw pixels rather than features. The first tier in a classifier is for automatically defining features based on raw image input, while the second tier makes decision. Compared to conventional feature based image classification methods, Two-Tier GP achieved better accuracies on a range of different tasks. Furthermore by using the features defined by the first tier of these Two-Tier GP classifiers, conventional classification methods obtained higher accuracies than classifying on manually designed features. Analysis on evolved Two-Tier image classifiers shows that there are genuine features captured in the programs and the mechanism of achieving high accuracy can be revealed. The Two-Tier GP method has clear advantages in image classification, such as high accuracy, good interpretability and the removal of explicit feature extraction process. © 2012 IEEE.
Automatic Design of Scheduling Policies for Dynamic Multi-objective Job Shop Scheduling via Cooperative Coevolution Genetic Programming
Authors: Nguyen S , Zhang Mengjie , Johnston M , Tan K Chen
Published: October 2020

A scheduling policy strongly influences the performance of a manufacturing system. However, the design of an effective scheduling policy is complicated and time consuming due to the complexity of each scheduling decision, as well as the interactions among these decisions. This paper develops four new multi-objective genetic programming-based hyperheuristic (MO-GPHH) methods for automatic design of scheduling policies, including dispatching rules and due-date assignment rules in job shop environments. In addition to using three existing search strategies, nondominated sorting genetic algorithm II, strength Pareto evolutionary algorithm 2, and harmonic distance-based multi-objective evolutionary algorithm, to develop new MO-GPHH methods, a new approach called diversified multi-objective cooperative evolution (DMOCC) is also proposed. The novelty of these MO-GPHH methods is that they are able to handle multiple scheduling decisions simultaneously. The experimental results show that the evolved Pareto fronts represent effective scheduling policies that can dominate scheduling policies from combinations of existing dispatching rules with dynamic/regression-based due-date assignment rules. The evolved scheduling policies also show dominating performance on unseen simulation scenarios with different shop settings. In addition, the uniformity of the scheduling policies obtained from the proposed method of DMOCC is better than those evolved by other evolutionary approaches. © 1997-2012 IEEE.
Genetic Programming for Multiclass Texture Classification Using a Small Number of Instances
Authors: Al-Sahaf Harith , Zhang Mengjie , Johnston M
Published: October 2020

© Springer International Publishing Switzerland 2014. The task of image classification has been extensively studied due to its importance in a variety of domains such as computer vision and pattern recognition. Generally, the methods developed to perform this task require a large number of instances in order to build effective models. Moreover, the majority of those methods require human intervention to design and extract some good features. In this paper, we propose a Genetic Programming (GP) based method that evolves a program to perform the task of multiclass classification in texture images using only two instances of each class. The proposed method operates directly on raw pixel values, and does not require human intervention to perform feature extraction. The method is tested on two widely used texture data sets, and compared with two GP-based methods that also operate on raw pixel values, and six non-GP methods using three different types of domain-specific features. The results show that the proposed method significantly outperforms the other methods on both data sets.
