High specific stiffness materials are used to design the space payload components. These components should sustain the extreme environmental conditions throughout their life cycle, without failure. Space missions need lightweight materials which are mechanically strong with high thermal and electric conductivities. Carbon fiber reinforced polymer (CFRP) offers considerable mass saving and high strength, which is widely used for space payload components. However, it has limitations to replace the traditional space-qualified materials due to its low conductivity. Carbon Nanotubes (CNTs) are efficient with greater electrical and thermal conductivities. For CNTs to be seen as effective reinforcements for attaining high strength and conductivity of polymer composites, they need to meet the criteria of being well-dispersed by the solution mixing method. The quality of the CNT nanocomposite relies upon several parameters like the type of CNTs, purity, aspect ratio, amount of loading, alignment and interfacial adhesion between the nanotube and polymer. The performance of the CNT-CFRP composite depends on the successful execution of the processing technique. It has been intended in this review paper to highlight the enhancement of the mechanical, thermal and electrical properties of the composite, and the challenges in achieving it. An attempt has been made to optimize the process parameters to fabricate space payload components which can be excellent alternatives to the existing high-density materials. Moreover, this review research is the need of the hour for prominent space agencies such as ISRO and NASA for their future inter-planetary missions, where payload weight needs to be kept light without making any compromise on the performance index.

Published: September 2022

Ferric oxide nanoparticles were synthesized by eco-friendly green synthesis and chemical synthesis methods. FeO nanoparticles were synthesized by Chemical co-precipitation method associated with microwave irradiation method and were characterized by XRD, FTIR, SEM, EDAX and Antibacterial Activity. The X-ray Diffraction (XRD) pattern analysis has revealed the crystal structure of FeO. The FTIR pattern has represented the functional groups of the prepared sample. The morphology and purity of the samples were analyzed by using Scanning Electron Microscopy and Energy Dispersion X-ray Diffraction analysis. The Antibacterial activity of the FeO nanoparticles were tested with gram positive Staphylococcus aureus and Bacillus subtilis, gram negative Escherichia coli and Pseudomonas aeruginosa. The results matched well with the standard values.
Concealed information under stress: A test of the orienting theory in real‐life police interrogations
Authors: Verschuere Bruno , Meijer Ewout , De Clercq Armand 
Published: September 2022

Purpose. The concealed information test (CIT) is a polygraph test that assesses recognition of critical (e.g., crime) information. Laboratory studies showing stronger heart rate deceleration to concealed compared to control information indicate that the orienting response (OR) accounts for responding in the CIT. An important restriction to these findings is that laboratory circumstances impose little or no stress on the examinees, and that under real‐life stress defensive responding may occur. Method. To examine the validity of the CIT under realistic stress, we analysed the data from 65 card tests conducted during real‐life police polygraph interrogations. Results. Baseline heart rate was higher than that observed in the laboratory, confirming that the situation was stress inducing. As in the laboratory, the concealed cards elicited greater heart rate deceleration compared to the control cards. Conclusions. The data support the OR theory of the CIT under real‐life stress.
Women with perinatal suicidal ideation–A scoping review of the biopsychosocial risk factors to inform health service provision and research
Authors: Bright Ann-Marie , Doody Owen , Tuohy Teresa 
Published: September 2022

Objectives
This review aims to map the existing evidence on perinatal suicidal ideation, identify biopsychosocial risk factors associated with suicidal ideation and make recommendations for service provision and future research.

Methods
Scoping review guided by Arskey’s and O’Malley’s (2005) framework. Five academic databases (PsycINFO, MEDLINE, CINAHL, ASSIA and Academic Search Complete) were searched from 1st January 2009 to 1st April 2022. Studies were screened by title, abstract and full text against inclusion and exclusion criteria. Primary qualitative, quantitative and mixed-methods studies, written in English pertaining to perinatal suicidal ideation were included. Forty-one studies met the eligibility criteria, data were extracted and narratively synthesised. Findings are reported in accordance with the PRISMA-SR extension.

Key conclusions
Findings were mapped onto the biopsychosocial framework and include sleep deprivation, maternal age, pregnancy complications, mood disorders, intimate partner violence, childhood maltreatment/abuse, low socioeconomic status, alcohol and tobacco misuse, miscarriage/perinatal loss, birth trauma and sleep deprivation. The findings demonstrate that the biopsychosocial risk factors for perinatal suicidal ideation are varied and complex.

Implications for practice
The minimisation of women’s experiences may lead to detrimental consequences and there is a need for increased knowledge of mental health problems by those working with women in the perinatal period to ensure safety planning conversations occur with every woman meeting ‘at risk’ criteria.

Published: September 2022

BackgroundDue to the coronavirus disease 2019 (COVID-19) pandemic, hygienic behaviors became a new norm since January 2020. The hygiene hypothesis predicts that an excessively hygienic environment may adversely affect human health.ObjectiveWe quantified the effect of COVID-19 on immunological parameters linked to the hygiene hypothesis.MethodsWe examined age-specific levels of total nonspecific immunoglobulin G (IgG) and IgE in individuals who visited Fukuoka Tokushukai Hospital between 2010 and 2021. Pre-COVID (2010–2019) and COVID (2020–2021) periods were compared.ResultsIgG levels steadily decreased throughout Pre-COVID period. IgG levels fell abruptly from the pre-COVID period to the COVID period in all age groups (P = 0.0271, < 0.3 years; P = 0.0096, 0.3–5 years; P = 0.0074, ≥ 5 years). The declines in IgG in < 0.3 years and that in ≥ 5 years accelerated during the COVID period. IgE levels were seasonal, but did not change noticeably from the pre-COVID to COVID period. IgG levels recorded for patients with Kawasaki disease (KD) (mean 709 mg/dL) were significantly lower than for matched control subjects (826 mg/dL) (P<0.0001).DiscussionHygienic behaviors during the COVID-19 outbreak decreased the chance of infection, which may explain the decreases in IgG levels in children and adults. Neonatal IgG declined, possibly because of the decrease in maternal IgG.ConclusionHygienic behaviors decreased the IgG levels in all age groups, from neonates to adults. This downturn in IgG may lead to vulnerability to infections as well as to KD.
On being Poor‐by‐Choice: A Philosophical Critique of the Neoliberal Poverty Perspective
Authors: Dixon John 
Published: September 2022

AbstractAbstractNeoliberalism is an economic, social, and political philosophy that derives, but significantly deviates, from classical liberalism. It has supreme trust in the marketplace and in the omniscience of market forces. It postulates that poverty is an objectively knowable social phenomenon. It theorizes that poverty's causal explanation is grounded in the inappropriateness of the hopes, aspirations, and goals of those living in poverty. It moralizes that the poor have a moral obligation to critically assess the consequences for themselves and others of their decisions not to work even when work is available, for which they should be held responsible. It concludes that the work‐shy poor‐bychoice — the undeserving poor — cannot be trusted not to abuse tax‐finance welfare support. The paper explicates, briefly, the philosophical underpinnings of neoliberalism as a social science paradigm, so as to facilitate, secondly, the exploration of its perspective on human nature, which informs, thirdly, its perspective on poverty. It concludes that neoliberalism is unable to speak with any certainty about the nature, causes, and consequences of poverty and its solution. The neoliberal poverty discourse is, essentially, a discourse on human nature. It asserts that the poor can choose not to be poor. This gives rise to an ideologically informed, assumption‐based approach to anti‐poverty policy.
Having Their Say: Rural Mothers Talk about Welfare
Authors: Dolan Elizabeth M. , Seiling Sharon B. , Braun Bonnie , Katras Mary Jo 
Published: September 2022

AbstractAbstractThe public's perception of persons who rely on public assistance is generally negative. The surprising element is that mothers who are themselves reliant on welfare also hold these negative attitudes. This paper explored the attitudes toward and experiences with welfare of rural low income mothers using data from the Rural Families Speak longitudinal, multi‐state project. Consistent with prior research, the majority of rural mothers spoke disparagingly of those relying on “welfare.” They saw themselves in a different light because they were in need and they used “public assistance” to help their families survive. The rural mothers also spoke of incidents in which they and their family members had experienced discrimination due to their use of welfare benefits.

produces a subset of the Kähler–Einstein locus, i.e. of the locus given by all prescribed singularities that admit Kähler–Einstein metrics. In particular, we prove that many K-stable manifolds admit all possible Kähler–Einstein metrics with prescribed singularities. Conversely, we show that enough positivity of the α-invariant function at nontrivial prescribed singularities (or other conditions) implies the existence of genuine Kähler–Einstein metrics.
Finally, through a continuity method we also prove the strong continuity of Kähler–Einstein metrics on curves of totally ordered prescribed singularities when the relative automorphism groups are discrete.
Frame shifting and fictive motion in Shelley’s poetic sublime
Authors: Bruhn Mark J. 
Published: September 2022

AbstractIn a key article on “Foregrounding and the sublime” (2007), David S. Miall outlined astylisticas opposed torepresentationalapproach to the sublime in verbal art, focusing not on the object or scene that provokes sublime experience but instead on forms of poetic language that may evoke an analogously sublime experience in the reader. Miall theorized that such forms would be foregrounding devices, and his analysis of Percy Shelley’s epistolary and verse accounts of Mont Blanc identified four such devices in particular: explicit discourse of defamiliarization, deviant syntax, ultimately unimaginable images, and mind-nature blending through deictic shifts. In honor of David, this article imitates his method in order to (a) redefine the fourth of these devices in more general terms of spatial reference frame shifting and (b) nominate fictive motion constructions as a fifth foregrounding device in Shelley’s poetic sublime.

Abstract
The study was aimed to investigate the role and mechanism of long non-coding RNAs (lncRNA) myocardial infarction-associated transcript (MIAT) in prostate cancer. The relationships between lncRNA MIAT and miR-361-3p, miR-361-3p and cell cycle and apoptosis regulator 2 (CCAR2) were predicted by StarBase and TargetScan, and verified by dual-luciferase reporter assay and RNA pull-down assay. Quantitative real-time PCR assay was performed to detect the mRNA expression of lncRNA MIAT, miR-361-3p, CCAR2, Bax, and Bcl-2 in the prostate cancer tissues or cells. The protein levels of CCAR2, Bax, and Bcl-2 were detected by Western blot analysis. The cell viability and apoptosis were detected by MTT assay and Flow cytometry analysis, respectively. lncRNA MIAT was upregulated, while miR-361 was downregulated in the prostate cancer tissues and Du145 cells. lncRNA MIAT negatively regulated miR-361-3p expression in Du145 cells. Downregulating lncRNA MIAT decreased the cell viability, induced the cell apoptosis, increased Bax expression, and decreased Bcl-2 expression in Du145 cells, while the effects were reversed by downregulating miR-361-3p or CCAR2 upregulation. Moreover, CCAR2 upregulation reversed the effects of miR-361-3p upregulation on Du145 cell viability and apoptosis. In conclusion, lncRNA MIAT participated in prostate cancer by regulating cell proliferation and apoptosis via miR-361-3p/CCAR2 axis.

Published: September 2022

Abstract
Scanned reactive-ion-beam etching method was proposed to transfer two-dimensional mask patterns into quartz substrate, which would produce a larger-size and polarization-independent two-dimensional grating. This method was realized by moving grating substrate in a unidimensional scanning manner and adjusting ion beam density in the vertical scanning direction. Graphite plates between the ion beam source and the substrate were used to correct the beam density. The original Gaussian ion beam density was changed to a uniform distribution to establish a knife-edge shape around the vertical scanning direction. Therefore, a large-area pattern with consistent depth and duty cycle would be engraved into a quartz substrate. A two-dimensional, 1200 groves/mm grating with an 85-mm × 85-mm area was fabricated under scanned reactive-ion-beam etching method and exhibited a 0.197λ (λ = 632.8 nm) diffraction wave front. At 780 nm, the efficiency nonuniformity was less than 9%, and the average diffraction efficiencies of transverse-magnetic and transverse-electric polarized light were 57.2 and 58.0%, respectively. The large-size two-dimensional grating with uniform diffraction efficiency and polarization independence enabled grating displacement measurement with high resolution, long measurement range, multiple degrees of freedom, and potential miniaturization.

Abstract
Black soybean (Glycine soja (L.) Merril) is one of the potential agricultural commodities in Indonesia. The multilocation trial is the primary requirement for variety release before farmers can widely use the new varieties. Various stability measurements on grain yields will provide more accurate information in selecting superior lines. The aims of the study were to: (i) identify the effect of genotype by environment interactions (G×E) on black soybean grain yields; (ii) select the black soybean lines with stable and high grain yields in different agroecosystems; and (iii) determine the best representative environment for testing black soybean lines. The field trials used an augmented design that was applied in three blocks for each location. The research was conducted in West Java, Indonesia, specifically in Sumedang, Indramayu, and Majalengka. The three locations are traditionally soybean production areas in West Java. The results showed that G×E significantly affected grain yields, with a contribution of 38.35%. Based on the results of stability testing using parametric, non-parametric, and genotype plus genotype by environments (GGE) biplot measurements, the G13, G22, G25, and G26 lines were considered the most stable and produced the highest yields in the three agroecosystems. In addition, Sumedang is the most representative location for testing black soybeans in Indonesia. Therefore, the four lines can be proposed as new superior lines for black soybeans with high yields and stability in three environments. Information about the relationship between the yield stability parameters can be used for the most accessible parameter selection.
The embodied enactment of politeness metapragmatics
Authors: Brown Lucien , Kim Soung-U , Kim Hyunji 
Published: September 2022

Abstract
Whereas previous research on metapragmatic talk has tended to focus on what people say about politeness, the current paper additionally explores how people talk about politeness. More specifically, we extend our analysis to the embodied resources, including gestures and nonverbal behaviour, that people use when enacting politeness talk. The data comes from two semi-structured interviews that we conducted with South Korean participants, both of whom were middle-aged university professors. We subjected the data to three rounds of analysis. First, we thematically coded the content of the narratives, revealing important differences in how these two participants from the same language background conceived of politeness. Second, we analyzed the appearance of verbal and non-verbal markers of deferential politeness. This analysis revealed that the overall bodily comportment of the two participants closely matched the different politeness narratives that they inhabited. Third and finally, we examined how the participants used bodily movements when evoking specific embodied practices related to politeness, and used embodied behaviours to represent abstract politeness-related concepts and map them onto spatial locations. Overall, the analysis shows that metapragmatic talk about politeness is an embodied achievement and thus needs to be treated within the remit of the multimodal turn in politeness research.

Published: September 2022

Abstract
Polymers like polydimethyl siloxane (PDMS) and polyethylene terephthalate (PET) have long been used as substrate materials for stretchable and flexible microelectromechanical systems (MEMS)-based applications. However, the ever-increasing demand of these materials and difficulty in frequent availability of such materials has also increased the cost. Thus, the study of alternate low-cost and easily available materials has become inevitable. Therefore, in this article, we have reported various research results related to BS-8599 V7 elastomer, a commonly available low-cost, silicone-based polymer alternative to PDMS and PET for stretchable and flexible MEMS applications. Mechanical properties were determined using tensile and compression tests according to ASTM-D412 Type C, Standard Test Methods for Vulcanized Rubbers and Thermoplastic Elastomers—Tension and ASTM-D575, Standard Test Methods for Rubber Properties in Compression, standards, respectively, thermal behavior was studied using thermal gravimetric analysis with hardness and elongation tests, chemical integrity of the polymer was observed by mass decomposition of the polymer in various chemical environments, and bio-compatibility of the polymer was studied by skin patch test to check its compatibility with the human epidermis. Finally, an adhesion test was performed by coating zinc oxide nanoparticle film on the polymer surface to demonstrate its application toward low-cost stretchable and flexible thin film devices. The analysis of the experimental data reveals that this material is highly stretchable and flexible, chemically inert, possesses good thermal stability, and can be used as a low-cost alternate substrate platform for various MEMS-based applications.
Visual Working Memory Recruits Two Functionally Distinct Alpha Rhythms in Posterior Cortex
Authors: Rodriguez-Larios Julio , ElShafei Alma , Wiehe Melanie , Haegens Saskia 
Published: September 2022

AbstractOscillatory activity in the human brain is dominated by posterior alpha oscillations (8–14 Hz), which have been shown to be functionally relevant in a wide variety of cognitive tasks. Although posterior alpha oscillations are commonly considered a single oscillator anchored at an individual alpha frequency (∼10 Hz), previous work suggests that individual alpha frequency reflects a spatial mixture of different brain rhythms. In this study, we assess whether independent component analysis (ICA) can disentangle functionally distinct posterior alpha rhythms in the context of visual short-term memory retention. Magnetoencephalography (MEG) was recorded in 33 subjects while performing a visual working memory task. Group analysis at sensor level suggested the existence of a single posterior alpha oscillator that increases in power and decreases in frequency during memory retention. Conversely, single-subject analysis of independent components revealed the existence of two dissociable alpha rhythms: one that increases in power during memory retention (Alpha1) and another one that decreases in power (Alpha2). Alpha1 and Alpha2 rhythms were differentially modulated by the presence of visual distractors (Alpha1 increased in power while Alpha2 decreased) and had an opposite relationship with accuracy (positive for Alpha1 and negative for Alpha2). In addition, Alpha1 rhythms showed a lower peak frequency, a narrower peak width, a greater relative peak amplitude and a more central source than Alpha2 rhythms. Together, our results demonstrate that modulations in posterior alpha oscillations during short-term memory retention reflect the dynamics of at least two distinct brain rhythms with different functions and spatiospectral characteristics.
