Stellar magnetic activity and the butterfly diagram of Kepler-63
Authors: Netto Y. , Valio A. 
Published: January 2020

Context. The study of young solar-type stars is fundamental for better understanding the magnetic activity of the Sun. Most commonly, this activity manifests itself in the form of spots and faculae. As a planet in transit crosses in front of its host star, a dark spot on the stellar surface may be occulted, causing a detectable variation in the light curve. Kepler-63 is a young solar-like star with an age of only 210 Myr that exhibits photometric variations compatible with spot signatures. Because the planet that orbits it is in an almost polar orbit, different latitudes of the star can be probed by the method of spot transit mapping.
Aims. The goal of this work is to characterise the spots of Kepler-63 and thus decipher the behaviour of the young Sun. Because planetary orbit is highly oblique, the latitudinal distribution and thus the differential rotation of the spots may be determined.
Methods. A total of 150 transits of Kepler-63b were observed in the short-cadence light curve, corresponding to a total duration of about four years. Each transit light curve was fit by a model that simulates planetary transits and allows including starspots on the surface of the host star. This enables the physical characterisation of the spot size, intensity, and location. We determined the spot position in a reference frame that rotates with the star, and thus obtained the latitudinal distribution of the spots.
Results. We fit a total of 297 spots and determined their sizes, intensities, and positions. The longitude and latitude of the spots were calculated in a reference frame that rotated with the star. The latitude distribution of spots exhibits a bimodality with a lack of spots around 34°. Moreover, the spot sizes tend to be larger close to the equator, but decrease toward the latitude distribution gap, after which they again increase toward the poles. High-latitude spots dominate the magnetic cycle of Kepler-63. For a mean stellar rotation period of 5.400 d, 59 spots were found at approximately the same longitude and latitude on a later transit. Some of these spots were detected eight transits later. This shows that the lifetimes of spots can be at least 75 d.
Conclusions. The geometry of the Kepler-63 system, enabled us to build a starspot butterfly diagram, similar to that of sunspots. It was also possible to infer the differential rotation of Kepler-63 from the spots at different latitudes. This star was found to rotate almost rigidly with a period of 5.400 d and a relative shear close to 0.01% for latitudes lower than 34°, whereas the high latitudes do not follow a well-behaved pattern.
Reflex Photosensitive Epilepsy

Published: January 2020

AbstractReflex seizure provoked by light or pattern stimulation are an interesting and, at times, difficult to treat entity. Such seizures occur in patients with a variety of well-described epileptic syndromes, although in most spontaneous seizures are also described. This paper attempts to describe epileptic syndromes with primarily light or pattern provoked seizures.
Severe Hyponatraemia Associated with the Use of Arginine–Vasopressin in Two Neonates with Complex Congenital Heart Disease
Authors: Leister Nicolas , Rohe Daniel , Schumacher Christine , Trieschmann Uwe , Menzel Christoph , Hannes Tobias 
Published: January 2020

AbstractWe report two cases of neonates with complex congenital heart disease and volume, catecholamine, and corticosteroid refractory shock treated with arginine–vasopressin. Arginine–vasopressin was able to reverse critical hypotension, but both patients developed severe hyponatremia, which recovered after discontinuation of arginine–vasopressin. Close control and prompt substitution of serum sodium is required in neonates with advanced heart failure on high-dose vasopressin therapy.
A construction-based account of the synchrony and diachrony of the Chinese middle construction
Authors: Chen Yue 
Published: January 2020

Abstract
Chinese middle construction (Chinese MC) uses the form ‘N+V+qilai+C’ to express passive
meaning. This study has shown that Chinese MC’s internal connections can be reflected by its synchronic hierarchy. Chinese MC
expands horizontally through argument structure and vertically through semantics and its expansion mechanism can be explained by
the varying abstraction model of categorization which combines the prototype and the exemplar model. This study has also validated
the truth that Chinese MC is a concept encompassing unclear boundaries within its members by using the schematic network model
which is the combination of the radial set model and the overlapping set model to represent the internal connections of Chinese
MC. By connecting Chinese MC with patient-subject sentences, this study has shown that the expansion of Chinese MC is affected by
other structures. Finally, this study has unveiled the affinity between constructionalization and grammaticalization by examining
how Chinese MC relates to V-qilai’s grammaticalization.
Modal particle meanings
Authors: Schoonjans Steven 
Published: January 2020

Abstract
One of the challenges of modal particle research is the search for appropriate ways to describe the meanings these particles convey. As these meanings are subtle and situated at the abstract and non-propositional level of intersubjective meaning making, the function of the particles is notoriously hard to pin down. As a consequence, scholars also disagree on what the precise relation between different but related particles is. In this paper, I show that gesture analysis can shed new light on these issues. By looking at the gestures used with the German particles denn, ja, doch, eben, einfach, and halt, the paper illustrates how studying gestures can lead to a better understanding of the particles and their mutual relations by showing how gesture data can offer new evidence for existing hypotheses and help in finding a way out of matters of discussion.
The effects of L1 congruency, L2 proficiency, and the collocate-node relationship on the processing of L2 English collocations by L1-Chinese EFL learners
Authors: Ding Chen , Reynolds Barry Lee 
Published: January 2020

AbstractThis study investigated the effects of first language (L1) congruency, second language (L2) proficiency, and the collocate-node relationship (i.e., verb-noun, adjective-noun, noun-noun) on collocation processing by logographic L1-Chinese learners of English. Comparisons were made of accuracy rates and response times to a collocation lexical decision task completed by L1-Chinese English as a Foreign Language (EFL) English Majors (n = 30), L1-Chinese EFL non-English Majors (n = 30), and L1-English Native Speakers (n = 26). Analysis of the data revealed that while congruent collocations were processed more accurately and faster than incongruent collocations by both L1-Chinese participant groups, the English Majors showed a processing advantage over their non-English Major peers. Further analysis revealed a processing advantage for noun-noun collocations, providing additional evidence in explaining the difficulties L1-Chinese have in acquiring verb-noun collocations. These results and other nuanced statistical findings are discussed in relation to pedagogical means of enhancing L2 collocation acquisition by L1-Chinese speakers.
The salience of local schemas in a productive word-formation process
Authors: Twardzisz Piotr , Nowosielska Barbara 
Published: January 2020

Abstract
Word-formation rules of a generative type are insufficient to describe a mechanism which appears to be productive, on the one hand, but is also irregular in its productivity, on the other. Cognitive morphological accounts have stressed the importance of a wide range of more and less detailed schemas (rather than rules), sanctioning different kinds of novel formations. This article addresses the issue of morphological productivity in the context of the formation of abstract deverbal action nouns, also known as Nomina Actionis, with names of political states as derivational bases. The very number and variety of relevant lexicalized nominalizations as well as hapax legomena is impressive, which makes the phenomenon look productive. The data obtained from COCA and specialist literature show interesting tendencies and gaps in the system. Numerous nominalizations are motivated semantically and pragmatically and are sanctioned by local schemas.
Making do
Authors: Gustafsson Hana 
Published: January 2020

Abstract
This paper argues that the cognitive usage-based model enhanced by a complexity theory perspective can provide
useful insights into L2 learners’ non-target-like use of L2 phraseological chunks. Firstly, L2 chunks are conceptualized here as
L2 complex form-meaning mappings subject to developmental schematization and entrenchment, as well as productive cut-and-paste
mechanisms. Traces of these mechanisms at community level are interpreted as emergent patterns, a complexity theory concept in
line with the cognitive usage-based model. Next, learner expressions for two task-elicited notions (depositing money and
donating money) in a community of L2 English learners (N = 167; L1 Dutch) are analyzed for emergent
patterns at different levels of schematicity. The findings indicate that L2 phraseological chunks are not constructed from a
target-like initial exemplar that becomes entrenched or schematized. The paper concludes that within the cognitive usage-based
model this is a major impeding factor in L2 learners’ target-like use of L2 phraseological chunks.
The source-path-goal image schema in gestures for thinking and teaching
Authors: Williams Robert F. 
Published: January 2020

AbstractThis article examinessource-path-goalimage-schematic structure in gestures used to solve counting problems (gesture for thinking) and to teach children how to read a clock (gesture for teaching). The analyses illustrate how path schemas inherent in idealized cognitive models are exhibited in gesture forms and in gesture sequences and combinations, manifesting conceptual content beyond that articulated in speech. While at times the path structure is incidental, enacting part of a cognitive model that is not the focus of discourse, at other times the path structure is essential, in that listeners must perceive thesource-path-goalstructure in the gesture in order to construct the proper understanding. The examples support the view that image schemas at the heart of cognitive models partly motivate and structure gestures for cognitive and communicative purposes, and that listener attunement to this structure contributes to intersubjective understanding and the perpetuation of cultural practices for distributed cognition.
The semantics of the English complex prepositionnext to
Authors: Brenda Maria 
Published: January 2020

AbstractThe present paper is an analysis of the semantic structure of the complex spatial prepositionnext to. Theoretical concepts of the cognitive framework promote a deep understanding of spatial relations and their metaphorical transfers encoded by individual prepositional senses. Assuming the usage-based model of language, the study takes a closer look at corpus data which is the basis for proposing five distinct meanings of the preposition under investigation. Conceptual metaphor theory is used to explain metaphorical transfer of spatialnext toto abstract domains of human experience.
A cognitive linguistic view of control mechanism in Iranian culture

Published: January 2020

AbstractThis research deals with the conceptualizations ofeffatin Persian and seeks to find out how this cultural key concept regulates the sexuality of Iranians. The analysis of the data collected from the Persian newspaperKayhanindicates thateffatis part of a larger cultural model that operates to restrict the sexuality of Iranians and keep the sexes segregated. The analysis demonstrates thateffatexclusively functions to discipline the body and set limits to bodily desires. Within the identified cultural model,effat’s main task is to segregate men and women by creating a cover/barrier between them, blocking/concealing the ways through which sexual desire might be aroused. The results show that metaphor is the primary means of representing the functions ofeffat. Theeffat is a curtainandeffat is a barriermetaphors mark the boundaries between individuals and prohibited areas of the culture. Moreover, metaphors contribute to discovering the relationship betweeneffatand its most related concepts. Metaphorical conceptualizations ofeffatprovide significant evidence as to how embodied experience is informed and constituted by culture. The research also finds that the body bears the imprint ofeffat. Compared to anthropological accounts, this research provides a more comprehensive image of this concept by simultaneously taking into account the role of bodily, cognitive, social-cultural, and discursive representations in the formation of the cultural model ofeffat.
Losing your footing, losing your morality
Authors: Li Heng , Cao Yu 
Published: January 2020

AbstractWhat influences how people render their moral judgment? Focusing specifically on the conceptual metaphors “moral is upright” and “immoral is tilted”, we sought to investigate whether physical slant can influence people’s harsh moral judgment. Experiment 1 induced physical slant by having participants complete the questionnaire at a tilt table. We observed a significant effect with participants who experienced physical slant rendering a less severe moral judgment than did those who wrote their responses at a level table. Using a new manipulation of physical slant and a larger, more diverse sample, Experiment 2 asked participants to complete the questionnaires with rotated text or normal text. We observed a difference between the two groups: compared to participants who read the normal text, those with a visual experience of slant lessened the severity of their moral judgments. Taken together, the results showed that the consequence of tilted experience exerts downstream effects on moral reasoning, which suggests that incidental bodily experience affects how people render their decisions.
Mechanical and tribological behaviours of aluminium hybrid composites reinforced by CDA-B4C
Authors: Manikandan R , Arjunan T V 
Published: January 2020

Abstract
This study focuses on fabricating aluminium hybrid metal matrix composites reinforced with eco-friendly agro waste, cow dung ash and boron carbide by two stage stir casting. Weight percentage of cow dung ash and boron carbide were added in ratios of 2.5:7.5, 5:5, and 7.5:2.5. The effects on mechanical properties like hardness, tensile strength, impact strength, flexural strength and wear behaviour were studied. SEM and EDX analysis were employed to study the fracture mechanism for tensile, impact and wear specimens. Optical microstructure images reveal uniform distribution of particles and XRD analysis confirms the presence of reinforcements. Increasing CDA particles has reduced the density of the hybrid composite up to 8%. A maximum increase in hardness, tensile strength and wear resistance was up to 30%, 56% and 56% respectively, and then a slight decrease in impact was found in increasing the CDA particles. Dimples, transgranular cleavage facets, cracks and micro ploughing, micro cuttings are revealed from the fractured specimens of tensile, impact and wear respectively.

Authors: Suwunwong Thitipone , Patho Pimchanok , Choto Patcharanan , Phoungthong Khamphe 
Published: January 2020

Abstract
Magnetic biochars were prepared using Fe3O4 nanoparticle composites onto the surface of biochar derived from rice husk. The characteristics of magnetic biochar were characterized by scanning electron microscope, x-ray powder diffraction and Fourier-transform infrared techniques. The removal of rhodamine 6G dye by magnetic biochar, compared to pristine biochar was studied. The effects of pyrolysis temperature on rhodamine 6G adsorption was evaluated. Kinetic, isotherms and thermodynamic studies were carried out to investigate the adsorption mechanism of rhodamine 6G dye on magnetic biochar surface. The rhodamine 6G removal efficiency of Fe3O4-composited biochar (pyrolyzed at 500 °C) is higher than that of pristine biochar with maximum efficiency of 94% removal. The adsorption isotherm and kinetic studies indicated that the langmuir model, pseudo-first order and pseudo-second order models described well the rhodamine adsorption onto magnetic Fe3O4-biochar.
BMDx: a graphical Shiny application to perform Benchmark Dose analysis for transcriptomics data
Authors: Serra Angela , Saarimäki Laura Aliisa , Fratello Michele , Marwah Veer Singh , Greco Dario 
Published: January 2020

Abstract

Motivation
The analysis of dose-dependent effects on the gene expression is gaining attention in the field of toxicogenomics. Currently available computational methods are usually limited to specific omics platforms or biological annotations and are able to analyse only one experiment at a time.

Results
We developed the software BMDx with a graphical user interface for the Benchmark Dose (BMD) analysis of transcriptomics data. We implemented an approach based on the fitting of multiple models and the selection of the optimal model based on the Akaike Information Criterion. The BMDx tool takes as an input a gene expression matrix and a phenotype table, computes the BMD, its related values, and IC50/EC50 estimations. It reports interactive tables and plots that the user can investigate for further details of the fitting, dose effects and functional enrichment. BMDx allows a fast and convenient comparison of the BMD values of a transcriptomics experiment at different time points and an effortless way to interpret the results. Furthermore, BMDx allows to analyse and to compare multiple experiments at once.

Availability and implementation
BMDx is implemented as an R/Shiny software and is available at https://github.com/Greco-Lab/BMDx/.

Abstract

Background
Acute kidney injury (AKI) is a common complication in patients during intensive care unit (ICU) admission. AKI is defined as an increase in serum creatinine (SCr) and/or a reduction in urine output. SCr is a marker of renal function with several limitations, which led to the search for biomarkers for earlier AKI detection. Our aim was to study the predictive value of plasma neutrophil gelatinase-associated lipocalin (NGAL) at admission as a biomarker for AKI progression during the first 48 h of ICU admission in an unselected, heterogeneous ICU patient population.

Methods
We conducted a prospective observational study in an academic tertiary referral ICU population. We recorded AKI progression in all ICU patients during the first 48 h of ICU admission in a 6-week period. Plasma NGAL was measured at admission but levels were not reported to the attending clinicians. As possible predictors of AKI progression, pre-existing AKI risk factors were recorded. We examined the association of clinical parameters and plasma NGAL levels at ICU admission with the incidence and progression of AKI within the first 48 h of the ICU stay.

Results
A total of 361 patients were included. Patients without AKI progression during the first 48 h of ICU admission had median NGAL levels at admission of 115 ng/mL [interquartile range (IQR) 81–201]. Patients with AKI progression during the first 48 h of ICU admission had median NGAL levels at admission of 156 ng/mL (IQR 97–267). To predict AKI progression, a multivariant model with age, sex, diabetes mellitus, body mass index, admission type, Acute Physiology and Chronic Health Evaluation score and SCr at admission had an area under the receiver operating characteristics (ROC) curve of 0.765. Adding NGAL to this model showed a small increase in the area under the ROC curve to 0.783 (95% confidence interval 0.714–0.853).

Conclusions
NGAL levels at admission were higher in patients with progression of AKI during the first 48 h of ICU admission, but adding NGAL levels at admission to a model predicting this AKI progression showed no significant additive value.
Spectral analysis for gene communities in cancer cells
Authors: Kikkawa Ayumi 
Published: January 2020

Abstract
We investigate gene interaction networks in various cancer cells by spectral analysis of the adjacency matrices. We observe the localization of the networks on hub genes, which have an extraordinary number of links. The eigenvector centralities take finite values only on special nodes when the hub degree exceeds the critical value $d_c \simeq 40$. The degree correlation function shows the disassortative behaviour in the large degrees, and the nodes whose degrees are $d \gtrsim 40$ have a tendency to link to small degree nodes. The communities of the gene networks centred at the hub genes are extracted based on the amount of node degree discrepancies between linked nodes. We verify the Wigner–Dyson distribution of the nearest neighbour eigenvalues spacing distribution $P(s)$ in the small degree discrepancy communities (the assortative communities), and the Poisson $P(s)$ in the communities of large degree discrepancies (the disassortative communities) including the hubs.
