A novel fast power swing blocking strategy for distance relay based on ADALINE and moving window averaging technique
Authors: Jannati Mohsen , Mohammadi Mohammad 
Published: November 2020

AbstractThis study proposes a a novel efficient strategy for identifying symmetrical faults from power swings in order to improve the performance of distance relay. This method is based on two new indices and the use of adaptive linear neuron and moving window averaging technique, which is applied to the waveforms of the current. If the proposed algorithm detects power swings, it enables power swing blocking; and if it recognises the occurrence as a symmetrical fault, it resets the power swing blocking as quickly as possible. The efficiency of the proposed method has been tested in different conditions and compared to other methods from different points of view. Simulation results under different conditions in PSCAD and MATLAB software show that the proposed strategy is able to detect symmetrical faults from power swings with high accuracy. The high robustness of adaptive linear neuron and the moving window averaging technique has made the proposed method highly noise‐resistant; and also, because of its low computational cost, the response speed of the proposed strategy is very high, and hence its practical implementation is simple.
Multiscale structural complexity of natural patterns
Authors: Bagrov Andrey A. , Iakovlev Ilia A. , Iliasov Askar A. , Katsnelson Mikhail I. , Mazurenko Vladimir V. 
Published: November 2020

Significance
Structural complexity of patterns, systems, and processes is a very basic and intuitively clear concept in human’s perception of reality that is very difficult to describe quantitatively. A demand in a mathematical notion that properly reflects complexity of hierarchical nonrandom structures exists in many areas of science, from geology to social sciences. Here, we propose an easy to compute, robust, and universal definition of complexity based on interscale dissimilarity of patterns. Using classical magnetic patterns as an example, we demonstrate that our approach leads to maximization of complexity for the most visually nontrivial patterns and can be used to detect phase transitions with high accuracy, making it a promising tool for studying pattern formation in a variety of systems.
Topological Weaire–Thorpe models of amorphous matter
Authors: Marsal Quentin , Varjas Dániel , Grushin Adolfo G. 
Published: November 2020

Significance
Topological insulators respond to external fields in fundamentally different ways compared to trivial insulators. Combining topologically robust responses with the long history of large-scale growth and broad applications of amorphous materials, a door for technological progress opens. The absence of realistic models that exploit the accumulated knowledge of both fields, and the lack of criteria to establish when topological phases emerge in amorphous solids, stalls progress. Here we propose models that are realistic and topological and display useful symmetry properties despite their lack of periodicity. They allow us to predict when amorphous topological phases occur and their physical responses, opening up a path to identify, classify, and discover amorphous topological insulators.
Dirac cones and chiral selection of elastic waves in a soft strip
Authors: Lanoy Maxime , Lemoult Fabrice , Eddi Antonin , Prada Claire 
Published: November 2020

Significance
We monitor the propagation of in-plane elastic waves in an incompressible thin strip and observe a Dirac cone in a soft material. Additional remarkable wave features such as negative phase velocities, pseudo-zero group velocity, and one-way chiral selection are highlighted. These results are universal: Any thin strip made of any soft elastomer will display the same behavior. Dirac cones have inspired many developments in the condensed-matter field over the last decade. Our findings enable the search for analogs in the realm of soft matter, leading to a wide range of potential applications. Additionally, they are of practical interest for biologists since soft strips are ubiquitous among human tissues and organs.
Korean Bibimbap mothers’ family language policies (FLPs) for their children’s bilingualism in
Australia
Authors: Park Eun Kyong , Vass Gregory , Davison Chris 
Published: November 2020

Abstract
The influential role of parents has long been acknowledged as a key contributor to children’s bilingual development.
Parents’ home-based informal efforts to foster children’s bilingual abilities are described as family language policies (FLPs). The
important connection between bilingualism and FLP has been established, but to date there are few studies concerning Korean immigrant
families in Australia, highlighting their unique cultural values. According to traditional Korean cultural values, mothers play a central
role as An-hae (the sun inside) to facilitate their children’s language development (Kim, 2006).
This study aimed to create a clearer picture of Korean mothers’ beliefs about bilingualism and their FLPs. The participants were six Korean
mothers with their children attending a community language program in Sydney. There are two data sets for this study: a six-weeks’ FLP daily
log of each family and a focus group interview. A thematic analysis of these data revealed the richness and specificity of FLPs for
bilingual development. This paper concludes with implications for a future research agenda.
Desiderata for metaphor theory, the Motivation &
Sedimentation Model and motion-emotion metaphoremes
Authors: Zlatev Jordan , Jacobsson Göran , Paju Liina 
Published: November 2020

Abstract
Metaphor research has increasingly diversified,
leading to extensive disagreements. A set of desiderata for any
contemporary theory of metaphor are (i) to account for both
communication and cognition, (ii) to explain both universal and
culture-specific aspects, (iii) to achieve a balance between stable
structures and contextual processes, (iv) to apply not only to
different languages, but to other semiotic systems such as gesture,
(v) to provide clear theoretical and operational definitions. We
argue that a recent cognitive-semiotic theory, the Motivation &
Sedimentation Model (MSM) is capable of fulfilling these
desiderata. To evaluate predictions from the theoretical model we
compare motion-emotion metaphoremes, such as my heart
jumped, in six differentially related European
languages – English, Swedish, Spanish, Bulgarian, Finnish and
Estonian.
Evaluating metaphor accounts via their pragmatic effects
Authors: Colston Herbert L. 
Published: November 2020

Abstract
A prominent pragmatic effect of metaphor is
meaning enhancement (Colston,
2015). Relative to comparable non-metaphorical language,
metaphors can provide stronger, richer, or more poignant delivery of
a proposition, idea, attitude, emotion, schema, or other meaningful
construct. Metaphor constructions also alter their component
parts (e.g., source and target domains). The paper measures
pragmatic effect performance when metaphors are assembled in
different ways, as a means of evaluating metaphor accounts. In four
experiments metaphors were altered by using; (1) weak versus strong
SDs, (2) mixed versus unmixed SDs, (3) single versus double
instantiations of SDs, and (4) using standard metaphor versus simile
constructions. Observed differences (e.g., in meaning enhancement)
support the idea that metaphor understandings arise in part due to
embodied simulations.
Metaphor, metonymy and polysemy
Authors: Allan Kathryn 
Published: November 2020

Abstract
Polysemy is a basic principle of the lexis of
English, but the full range of senses of a lexeme and the ways in
which these interact are not often considered in accounts of
metaphor and metonymy. This paper presents a case study of the
lexeme dull, which develops multiple meanings that
do not appear to represent the kind of straightforward concrete >
abstract metaphorical mapping that might be assumed. Rather, the
complex semantic history of the word reveals gradual shifts in
meaning involving metonymy, and change motivated by analogy. I argue
that ignoring word histories risks synchronic ‘misreading’ of the
relationship between their senses (Geeraerts, 2015), and that polysemy should
be acknowledged more prominently in standard accounts.
Sources of verbal humor in the lexicon
Authors: Winter-Froemel Esme 
Published: November 2020

Abstract
Lexical items with a ludic potential have not
been systematically studied up to now. The aim of this paper is thus
to explore sources of humor in the French and Italian lexicon and to
investigate to what extent the notion of incongruity can explain the
humorous effects and ludic usage of lexical items. Incongruity will
be reinterpreted from a usage-based perspective, stressing the
interactional dimension of communication (see also Kotthoff, 1998; Onysko, 2016), which
defines the relative inappropriateness and pragmatic markedness of
the items. In addition, the semantic distance and (in)compatibility
of the meanings as well as the semiotic nature of the relevant
reference entities will be taken into account, and a typology of
relevant subtypes of incongruity will be proposed.
Gauging expansion in synchrony
Authors: Fløgstad Guro Nore , Rodríguez Louro Celeste 
Published: November 2020

Abstract
One of the hallmarks of present-day Rioplatense
Spanish is the highly specialised use of the periphrastic perfect or
Pretérito Perfecto Compuesto (PPC). Most
perfect nuances are instead encoded in this dialect through the
synthetic past or Pretérito Perfecto Simple (PPS).
Exploration of a novel corpus of historical media and theatre plays
shows that, in nineteenth century Rioplatense, the PPC was
productively used to encode hot news, hodiernality and hesternality.
These nineteenth century uses are in line with a cross-linguistic
perfect-to-perfective grammaticalization pathway but the path is
halted in present-day Rioplatense. We draw on cognitive
grammaticalization theory to argue that there is no determinacy in
grammaticalizing constructions: a source meaning does not uniquely
determine the path a grammaticalizing construction may take.
Auxiliary reduction in secondary grammaticalization
Authors: Howe Chad 
Published: November 2020

Abstract
At the center of grammaticalization studies has
been an effort to understand the interplay between form and function
throughout the development of a construction. A recent analysis by
Dehé & Stathi
(2016) has made the case that desemanticization (semantic
reduction) and erosion (phonetic reduction) occur in parallel and
that different phonetic patterns can be associated with different
degrees of grammaticalization. This paper approaches Dehé and
Stathi’s proposal by means of the periphrastic past (PP) in Spanish,
a form that shows considerable variation across dialects and has
been shown to display various degrees of grammaticalization (Howe 2013). Focusing
specifically on the PP’s use in sequenced past narratives in
Peninsular Spanish, this analysis observes the behavior of the haber
auxiliary and finds evidence for increased reduction/omission in
these innovative narrative contexts. The patterns of reduction shown
in this analysis are consistent with the claim made by Dehé and
Stathi regarding the association of specific reductive processes
with more advanced stages of grammaticalization. These data reveal a
coevolution of form and meaning with the PP not yet discussed in the
literature, one that has broader implications for the study of
periphrastic past forms in Romance.

Published: November 2020

Abstract
LiNi0.8Co0.1Mn0.1O2 (NCM811) is considered as a promising cathode material for lithium-ion batteries (LIBs) due to its advantages of high lithium storage capacity, low cost and excellent safety. However, lithium element of NCM series is easily lost in the preparation process, which leads to the rapid decline of cathode material capacity. Previous researches show that coating is an effective way to reduce the loss of elements, improve the electrochemical properties and thermal stability of the material. In this paper, the author focuses on different synthesis methods and different molar (or weight) ratios of Li2ZrO3, finding out that different synthesis methods can affect the electrochemical performances of target materials and right now research result is that 1wt.% NCM811@ Li2ZrO3 has the best property among other molar (or weight) ratios of NCM811@ Li2ZrO3.

Authors: Ding Yanchun , Shi Guangfeng 
Published: November 2020

Abstract
With the high-speed development of the delicateness grinding, mechanical scratching and micro-cutting technology, scholars have become more and more interested in the forming mechanism and related characteristics of the negative rake angle tool. Based on DEFORM-2D forming software, this paper investigates the forming mechanism and related characteristics of the negative rake angle tool. Through the simulation comparison analysis, it is clear that as the negative rake angle decreased form 0° to 60° (the negative rake angle does not attain to the critical value), the shear angle becomes smaller, the ability of the chip formation in the front of the tool surface becomes weaker, the chip shape becomes blunter, the action state of the tool effect on the material is cutting and ploughing, and the tangential force and normal force increase, significantly. When the negative rake angle reaches the critical value (no chip formation, negative rake angle is approximately equal to -80°), the shear angle is approximately equal to 0°, no chip formed in front of the tool surface, the tool pure ploughing the material, and the tangential force and normal force both show a significant downward trend. Meanly, a triangular stagnant region appears in front of the tool surface when the negative rake angle decreased form -20° to -80°.

Authors: Li Dongyu , Li Xiaoqiang , Li Jingmao , Qu Shengguan 
Published: November 2020

Abstract
Nano-WC modified copper-iron-based oil bearing was prepared by powder metallurgy. The effect of sintering atmosphere on the microstructure, crushing strength, hardness and oil content of the oil bearing were studied. The results show that under the sintering condition of 865 °C×30min, when the sintering atmosphere is 100%N2, the sintering process stays in the early stage of sintering neck growth, there are a large number of irregular pores in the microstructure. The sintering densification is insufficient, and the sample is in the state of undersintering. When the sintering atmosphere is 100%H2, the dezincification of matrix phase α(Cu) is serious, and there are many long strip microcracks between metal particles. The effective connection between α(Cu) and Fe phase is cut off, so the density of sample is very low. When the sintering atmosphere is 75%H2+25%N2, α(Cu) forms a united whole through sufficient sintering diffusion bonding, and encapsulates the Fe-rich phase. The sintering densification is very sufficient, the pores in the microstructure tend to be circular. The sintered samples have good comprehensive properties, the density and oil content are 6.60 g/cm3 and 18.21vol.%, the crushing strength and hardness are 235.81 MPa and 42.41 HB, respectively, showing the best sintering state.

Authors: Wu Yan , Ren Haiping , Yang Zhongfang 
Published: November 2020

Abstract
To determine the effect of total nitrogen on the physical and mechanical properties and deformation characteristics of soil, samples were tested in the laboratory after being soaked in deionized water and different concentrations of nitrogen solution. The results indicate that the total nitrogen content has a significant influence on soil characteristics. Specifically, the plasticity index, specific gravity and effective cohesive strength of the samples decrease and the effective friction angle increases with increases in the total nitrogen concentration of the solution. The strain hardening phenomenon is observed in the stress-strain relationship, and the variation of the stress-strain curve of samples soaked in deionized water and nitrogen solution are highly similar. The peak shear strength of the samples initially decreased and then increased with increases in the total nitrogen concentration of the solution. The mineral composition, particularly the composition of clay minerals, is affected by the interaction with total nitrogen in the soil, leading to changes in the soil macro-characteristics.

Published: November 2020

Abstract
In order to achieve high strength 21-6-9 (HS-21-6-9) tube numerical control (NC) bending precision forming, the springback law and compensation should be studied for the HS-21-6-9 tube NC bending. By using a finite element (FE) simulation method, the effects of bending angle θ on springback angle Δθ and springback radius ΔR of the HS-21-6-9 tube NC bending were investigated. The results show that the Δθ increases linearly with the increase of the θ, and the relationship between the Δθ and the θ can be described as Δθ=2.47179+0.02208θ. The ΔR decreases along the curve with the increase of the θ, and the relationship between the ΔR and the θ can be described as ΔR=33.86587θ
−0.64431. The compensation methodology is proposed considering the Δθ and the ΔR simultaneously, and the viability of the methodology is validated by an example.

Authors: Wang Xinxin , Wang Nan 
Published: November 2020

Abstract
Zinc ferrite precursors are prepared by coprecipitation method using zinc nitrate and ferric nitrate as reactants, monohydrate ammonia and citric acid as precipitants and dispersants respectively. And zinc ferrite precursors are calcined at high temperature to obtain zinc ferrite photocatalysts at different temperatures(350°C, 450°C, 550°C). Methylene blue is used as substrates. The quality of the catalyst, the type of catalyst and the temperature of calcining are measured to study the photocatalytic performance. The results show that the preparation of zinc ferrite under 450°C has an optimal effect on the degradation of methylene blue dye. Compared with iron oxide and zinc oxide, the photocatalytic properties of zinc ferrite are superior to that of single oxide.
