Published: September 2021

AbstractTo enhance the surface properties of solids the mechanism of thin films is frequently used. Penetration, degradation, stiffness, illumination, diffusion, absorption, and electric performance are all characteristics of a bulk substance medium that a thin film can improve. In nanotechnology, thin film processing can be extremely useful. Therefore, the time-dependent nonlinearly convective stream of thin film nanoliquid over an inclined stretchable sheet with magnetic effect is investigated in current work. The features of mass and heat transport processes are explained using important factors like thermophoresis and Brownian movement. Nonlinear partial differential equations are obtained to model the time-dependent liquid film flow over an inclined surface, which are then turned into couple ordinary differential equations utilizing appropriate alterations. The results of the computation of the model problem are collected using an analytical approach Homotopy Analysis Method and presented the final finding numerically and graphically. During the flow assessment, the impact of individual flow factors such as magnetic, Brownian, and thermophoresis parameters on regular profiles (temperature, velocity, and concentration) are analyzed and found to be quite remarkable. Furthermore, the consequence of M and Nt factors on the velocity, concentration and thermal distribution leads to diminishing conduct. On the other hand, the thermal profile of the liquid film rises in response to the thermophoresis factor. The % wise variation in the skin friction, Nusselt number and Sherwood number versus physical parameters has been obtained and discussed.

AbstractThe oil yield, measured in oil extraction rate per hectare in the palm oil industry, is directly affected by the ripening levels of the oil palm fresh fruit bunches at the point of harvesting. A rapid, non-invasive and reliable method in assessing the maturity level of oil palm harvests will enable harvesting at an optimum time to increase oil yield. This study shows the potential of using Raman spectroscopy to assess the ripeness level of oil palm fruitlets. By characterizing the carotene components as useful ripeness features, an automated ripeness classification model has been created using machine learning. A total of 46 oil palm fruit spectra consisting of 3 ripeness categories; under ripe, ripe, and over ripe, were analyzed in this work. The extracted features were tested with 19 classification techniques to classify the oil palm fruits into the three ripeness categories. The Raman peak averaging at 1515 cm−1 is shown to be a significant molecular fingerprint for carotene levels, which can serve as a ripeness indicator in oil palm fruits. Further signal analysis on the Raman peak reveals 4 significant sub bands found to be lycopene (ν1a), β-carotene (ν1b), lutein (ν1c) and neoxanthin (ν1d) which originate from the C=C stretching vibration of carotenoid molecules found in the peel of the oil palm fruit. The fine KNN classifier is found to provide the highest overall accuracy of 100%. The classifier employs 6 features: peak intensities of bands ν1a to ν1d and peak positions of bands ν1c and ν1d as predictors. In conclusion, the Raman spectroscopy method has the potential to provide an accurate and effective way in determining the ripeness of oil palm fresh fruits.

Published: September 2021

Abstract
Purpose: ADME genes are those involved in the absorption, distribution, metabolism, and excretion (ADME) of drugs. In the present study, a non-small-cell lung cancer (NSCLC) risk prediction model was established using prognosis-associated ADME genes, and the predictive performance of this model was evaluated and verified. In addition, multifaceted difference analysis was performed on groups with high and low risk scores.
Methods: An NSCLC sample transcriptome and clinical data were obtained from public databases. The prognosis-associated ADME genes were obtained by univariate Cox and lasso regression analyses to build a risk model. Tumor samples were divided into high-risk and low-risk score groups according to the risk score. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses of the differentially expressed genes and the differences in the immune infiltration, mutation, and medication reactions in the two groups were studied in detail.
Results: A risk prediction model was established with seven prognosis-associated ADME genes. Its good predictive ability was confirmed by studies of the model's effectiveness. Univariate and multivariate Cox regression analyses showed that the model’s risk score was an independent prognostic factor for patients with NSCLC. The study also showed that the risk score closely correlated with immune infiltration, mutations, and medication reactions.
Conclusion: The risk prediction model established with seven ADME genes in the present study can predict the prognosis of patients with NSCLC. In addition, significant differences in immune infiltration, mutations, and therapeutic efficacy exist between the high- and low-risk score groups.
Application of the Challenge Point Framework During Treatment of Speech Sound Disorders
Authors: Matthews Tanya , Barbeau-Morrison Alexandra , Rvachew Susan 
Published: September 2021

Purpose
The purpose of this article is to provide trial-by-trial practice performance data in relation to learning (outcome probe data) as collected from 18 treatment sessions provided to children with severe speech sound disorders. The data illustrate the practice–learning paradox: Specific, perfect practice performance is not required for speech production learning.

Method
We detailed how nine student speech-language pathologists (SSLPs) implemented and modified the motor learning practice conditions to reach a proposed challenge point during speech practice. Eleven participants diagnosed with a severe speech sound disorder received high-intensity speech therapy 3 times per week for 6 weeks. SSLPs implemented treatment procedures with the goal of achieving at least 100 practice trials while manipulating practice parameters to maintain practice at the challenge point. Specifically, child performance was monitored for accuracy in five-trial increments, and practice parameters were changed to increase functional task difficulty when the child's performance was high (four or five correct responses) or to decrease functional task difficulty when the child's performance was low (fewer than four correct responses). The practice stimulus, type and amount of feedback, structure of practice, or level of support might be changed to ensure practice at the challenge point.

Results
On average, the children achieved 102 practice trials per session at a level of 58% correct responses. Fast achievement of connected speech with the lowest amount of support was associated with high scores on generalization probes. Even with high levels of error during practice, the children improved percent consonants correct with maintenance of learning 3 months posttreatment.

Conclusion
The results of this study show that it may not be necessary to overpractice or maintain a high degree of performance accuracy during treatment sessions to achieve transfer and retention of speech production learning.

Context.The Mid-Infrared Instrument (MIRI) onboard theJames WebbSpace Telescope (JWST) will provide imaging, coronagraphy, low-resolution spectroscopy, and medium-resolution spectroscopy at unprecedented sensitivity levels in the mid-infrared wavelength range. The Medium Resolution Spectrometer (MRS) of MIRI is an integral field spectrograph that provides diffraction-limited spectroscopy between 4.9 and 28.3 μm, within a field of view (FOV) varying from ∼13 to ∼56 arcsec square. The design for MIRI MRS conforms with the goals of the JWST mission to observe high redshift galaxies and to study cosmology as well as observations of galactic objects, and stellar and planetary systems.Aims.From ground testing, we calculate the physical parameters essential for general observers and calibrating the wavelength solution and resolving power of the MRS which is critical for maximizing the scientific performance of the instrument.Methods.We have used ground-based observations of discrete spectral features in combination with Fabry-Perot etalon spectra to characterize the wavelength solution and spectral resolving power of the MRS. We present the methodology used to derive the MRS spectral characterization, which includes the precise wavelength coverage of each MRS sub-band, computation of the resolving power as a function of wavelength, and measuring slice-dependent spectral distortions.Results.The ground calibration of the MRS shows that it will cover the wavelength ranges from 4.9 to 28.3 μm, divided in 12 overlapping spectral sub-bands. The resolving power isR ≳ 3500 in channel 1,R ≳ 3000 in channel 2,R ≳ 2500 in channel 3, andR ≳ 1500 in channel 4. The MRS spectral resolution optimizes the sensitivity for detection of spectral features with a velocity width of ∼100 km s−1which is characteristic of most astronomical phenomena JWST aims to study in the mid-infrared. Based on the ground test data, the wavelength calibration accuracy is estimated to be below one-tenth of a pixel (0.1 nm at 5 μm and 0.4 at 28 μm), with small systematic shifts due to the target position within a slice for unresolved sources that have a maximum amplitude of about 0.25 spectral resolution elements. The absolute wavelength calibration is presently uncertain at the level of 0.35 nm at 5 μm and 46 nm at 28 μm, and it will be refined using in-flight commissioning observations.Conclusions.Based on ground test data, the MRS complies with the spectral requirements for both theRand wavelength accuracy for which it was designed. We also present the commissioning strategies and targets that will be followed to update the spectral characterization of the MRS.
SN 1987A: Tracing the flux decline and spectral evolution through a comparison of SRG/eROSITA and XMM-Newton observations

Published: September 2021

Context. SN 1987A is the supernova closest to us observed in the past four centuries. It provides the unique opportunity of witnessing the birth and evolution of a supernova remnant. Monitoring the source in X-rays provides insights into the physics of the shock, the X-ray emitting plasma, and the interaction of the shock with the structures in the circumstellar medium. The source has been monitored by XMM-Newton EPIC-pn from 2007 to 2020. SRG/eROSITA also observed the source during its commissioning phase and first light in September and October 2019.
Aims. We investigated the spectral and flux evolution of SN 1987A in X-rays in the last 14 yr up to November 2020 using XMM-Newton and eROSITA observations.
Methods. We performed a detailed spectral analysis using a three-component plane-parallel shock model and analysed and modelled the EPIC-pn monitoring and eROSITA observations in a consistent manner.
Results. This paper reports a complete and the most recent flux evolution of SN 1987A in the soft (0.5−2 keV) and hard (3−10 keV) X-ray band. The flux in the soft band flattened around 9424 days and then displayed a turnover between 10 142 and 10 493 days, after which it showed a continued decline. At about the same time, a break in the hard-band flux time evolution slope was detected. This implies that the blast wave has now passed beyond the dense structures of the equatorial ring and is expanding farther into more tenuous circumstellar medium. The temporal evolution of the normalisations of the three shock components match the results of hydrodynamical simulations well, which predict a blue supergiant progenitor scenario. The trend in recent epochs indicates that the emission caused by the forward shock after leaving the equatorial ring and by the reverse shock in the ejecta is now becoming more dominant. The elemental abundances in the hot plasma component are significantly higher than those in the cooler component, indicating an origin in the reverse shock that propagates into the ejecta.
The eROSITA view of the Abell 3391/95 field: Case study from the Magneticum cosmological simulation

Published: September 2021

Context.Clusters of galaxies reside at the nodes of the cosmic web, interconnected by filamentary structures that contain tenuous diffuse gas, especially in the warm-hot phase. Galaxy clusters grow by mergers of smaller objects and gas that are mainly accreted through these large-scale filaments. For the first time, the large-scale cosmic structure and a long gas-emission filament have been captured by eROSITA on board the Spectrum-Roentgen-Gamma mission in a direct X-ray observation of the A3391/95 field.Aims.We investigate the assembly history of an A3391/95-like system of clusters and the thermo-chemical properties of the diffuse gas in it by connecting simulation predictions to the eROSITA observations with the aim to constrain the origin and nature of the gas in the pair-interconnecting bridge.Methods.We analysed the properties of a system resembling A3391/95, extracted from the (352h−1cMpc)3volume of the Magneticum Pathfinder cosmological simulations atz= 0.07. We tracked the main progenitors of the pair clusters and of surrounding groups back in time to study the assembly history of the system and its evolution.Results.Similarly to the observed A3391/95 system, the simulated cluster pair is embedded in a complex network of gas filaments, with structures aligned over more than 20 projected Mpc, and the whole region collapses towards the central overdense node. The spheres of influence (3 ×R200) of the two main clusters already overlap atz= 0.07, but their virial boundaries are still physically separated. The diffuse gas located in the interconnecting bridge closely reflects the warm-hot intergalactic medium, with a typical temperature of ~1 keV and an overdensityδ ~100 with respect to the mean baryon density of the Universe, and a lower enrichment level compared to the intra-cluster medium in clusters. We find that most of the bridge gas collapsed from directions roughly orthogonal to the intra-cluster gas accretion directions, and its origin is mostly unrelated to the two cluster progenitors. We find clear signatures in the surrounding groups of infall motion towards the pair, such as significant radial velocities and a slowdown of gas compared to dark matter. These findings further support the hypothesis that the Northern Clump (MCXC J0621.7-5242) cluster infalls along a cosmic gas filament towards Abell 3391 and might be merging with it.Conclusions.We conclude that in this configuration, the pair clusters of the A3391/95-like system are in a pre-merger phase and have not yet interacted. The diffuse gas in the interconnecting bridge is mostly warm filament gas and not tidally stripped cluster gas.
Of cityscapes, affect and migrant subjectivities in Kiran Desai’s Inheritance of Loss
Authors: Nanda Aparajita 
Published: September 2021

AbstractKiran Desai's Inheritance of Loss revolves around questions of identity and entities flawed by a deep sense of deprivation and loss left by colonization that manifests itself in various forms through generations. The novel chronicles the lives of an Anglophile Indian judge, Jemubhai Patel, whose educational sojourn in Britain permanently brands him as an alien both abroad and in his homeland, and of his orphaned 16-year-old granddaughter Sai, her tutor/lover Gyan, and Patel’s cook who pushes his son, Biju, to go seek his fortune in America. This paper seeks to discuss the lives of Jemubhai and Biju as it tracks the role of the city and its impact on the construction of their identities. This impact factor is further analyzed through affective theory, namely Jose Munoz’s concept of “disidentification,” a tactic of survival by which minoritarian subjects either consciously or unconsciously “neither assimilate nor strictly oppose the dominant regime.”
Pronunciation learning strategies
Authors: Szyszka Magdalena 
Published: September 2021

Abstract
The purpose of this chapter is to present the
results of a study that examined types of pronunciation learning
strategies (PLSs) used by high- (HA) and low-achieving (LA) L2
pronunciation learners. The participants completed six different
tasks and an open-ended questionnaire eliciting the participants’
PLSs deployed for a specific task. Subsequently, the individuals
were tested following the same instructions but different content in
order to designate high- and low-achievers on particular tasks. The
results revealed a considerable divergence in the strategy choice
for different tasks and a frequent use of strategy chains in both HA
and LA groups. Pedagogical practices informed by these findings are
suggested in order to better support effective strategy use by L2
pronunciation learners.

Integrating prosodic features in a children’s English
course
Authors: Vonzová Veronika , Skarnitzl Radek 
Published: September 2021

Abstract
The chapter reports on an experiment which
focused on the integration of prosody into an English course for
young children. Two groups of Czech primary school children (aged
6–7, n = 12 in each group) were analysed, one of
which received prosody-focused training and the other followed the
regular curriculum. The prosodic training targeted pitch range,
melodic suppression of unstressed syllables, and linking. We
analysed the children’s rendition of short chants after four and
eight months of instruction. Participants in the experimental group
had a wider pitch range and did not realise the typical Czech rise
between the stressed and post-stressed syllable. Linking was
partially present in both groups. The chapter is concluded with the
discussion of pedagogical implications.
‘Actually given’ versus ‘presented as given’ and ‘actually new’ versus ‘presented as new’
Authors: Berry Margaret 
Published: September 2021

Abstract
This paper considers the relevance of various approaches to the study of ‘Given’ and ‘New’ to a number of
practical problems: complaints from listeners to UK radio programmes that presenters place emphasis on the wrong words;
inaudibility of openings of utterances in radio news bulletins; and ambiguity of pronouns. Approaches to ‘Given’ and ‘New’ to be
discussed include those whose concerns are with intonation (e.g., Halliday & Matthiessen
2014), those who pay attention to definiteness/indefiniteness in the nominal group (e.g., Martin 1992), and those who are more concerned with what is in the minds of hearers and readers (e.g.,
Prince 1981; Lambrecht 1994). The
underlying questions that are being investigated are: How free are speakers and writers to assign ‘Given’ or ‘New’ status to
entities? Are there constraints on what they can do intonationally, or with definiteness, or with pronouns?
Worlds of evidence

Abstract
The Hillsborough football stadium disaster (1989) in Sheffield, UK, led to the deaths of 97 football fans and
resulted in the longest jury case in British legal history (2016). This article examines the witness statements of two Sheffield
residents who claim to have attended the match. Using a mixed-methods approach that incorporates a cognitive linguistic framework
(Text World Theory) with visualisation software (VUE) we consider both form and function of a number of linguistic features, such
as meta-narrative, evaluative lexis, syntax, and modality to investigate how institutional voices permeate and potentially distort
layperson narratives. Our analysis casts doubt on the veracity of the statements and raises questions about what can be
considered evidential in a forensic investigation.
The emergence of mind in Henry James’s notebook material
Authors: Álvarez-Amorós José A. 
Published: September 2021

AbstractInscribed in the field of cognitive narrative theory, this paper asks, and attempts to answer, a number of questions about the early emergence of mind in James’s notebook material for his short fiction. These questions essentially turn on the metarepresentational and aspectualizing potential of notebook entries in genetic relation to the finished tales, that is, on their capacity to present the projected storyworld, from its very conception, as a function of the subjectivity of one or several characters in the cognitive role of metarepresentational sources, or else as a dementalised lump of content to be aspectualised later in the process of execution. Analysis of the relevant notebook material yields a polarity between epistemic and contentual entries, and reveals a set of cognitive phenomena based on the alteration or continuity of the primitive balance of sources which allows one to conclude that James’s characteristic concern with the mental dynamics of his narratives, rather than being a compositional addition, was deeply embedded in his earliest fictional projects.
