AbstractPreparing polymeric coatings with well corrosion resistance and high thermal conductivity (TC) to prolong operational life and ensure service reliability of heat conductive metallic materials has long been a substantive and urgent need while a difficult task. Here we report a multifunctional epoxy composite coating (F-CB/CEP) by synthesizing cerium methacrylate and ingeniously using it as a novel curing agent with corrosion inhibit for epoxy resin and modifier for boron nitride through "cation-π" interaction. The prepared F-CB/CEP coating presents a high TC of 4.29 W m−1 K−1, which is much higher than other reported anti-corrosion polymer coatings and thereby endowing metal materials coated by this coating with outstanding thermal management performance compared with those coated by pure epoxy coating. Meanwhile, the low-frequency impedance remains at 5.1 × 1011 Ω cm2 even after 181 days of immersion in 3.5 wt% NaCl solution. Besides, the coating also exhibits well hydrophobicity, self-cleaning properties, temperature resistance and adhesion. This work provides valuable insights for the preparation of high-performance composite coatings with potential to be used as advanced multifunctional thermal management materials, especially for heat conduction metals protection.

AbstractTailoring the interfacial interaction in SiC-based anode materials is crucial to the accomplishment of higher energy capacities and longer cycle lives for lithium-ion storage. In this paper, atomic-scale tunable interfacial interaction is achieved by epitaxial growth of high-quality N doped graphene (NG) on SiC (NG@SiC). This well-designed NG@SiC heterojunction demonstrates an intrinsic electric field with intensive interfacial interaction, making it an ideal prototype to thoroughly understand the configurations of electron/ion bridges and the mechanisms of interatomic electron migration. Both density functional theory (DFT) analysis and electrochemical kinetic analysis reveal that these intriguing electron/ion bridges can control and tailor the interfacial interaction via the interfacial coupled chemical bonds, enhancing the interfacial charge transfer kinetics and preventing pulverization/aggregation. As a proof-of-concept study, this well-designed NG@SiC anode shows good reversible capacity (1197.5 mAh g−1 after 200 cycles at 0.1 A g−1) and cycling durability with 76.6% capacity retention at 447.8 mAh g−1 after 1000 cycles at 10.0 A g−1. As expected, the lithium-ion full cell (LiFePO4/C//NG@SiC) shows superior rate capability and cycling stability. This interfacial interaction tailoring strategy via epitaxial growth method provides new opportunities for traditional SiC-based anodes to achieve high-performance lithium-ion storage and beyond.
Awe: A Systematic Review within a Cognitive Behavioural Framework and Proposed Cognitive Behavioural Model of Awe

Published: August 2023

AbstractAwe is considered a transformational and multifaceted emotion. Vastness is the core cognitive appraisal associated with awe, which activates a need for cognitive accommodation. Increasingly, studies are evaluating awe’s dimensions including triggers, cognitive and emotional characteristics, and primarily beneficial outcomes. Additionally, numerous emotions have been conceptualised within a cognitive behavioural framework and cognitive behavioural models may be utilised to promote positive human qualities and experiences. Therefore, this paper outlines the results of a systematic review of the literature on awe from a cognitive behavioural perspective to propose a cognitive behavioural model. Databases searched included Psych Net, Science Direct, Scopus, Web of Science, PubMed, ProQuest, EBSCO, SAGE, JSTOR, Springer LINK, Taylor and Francis, and Wiley with the inclusion of peer reviewed articles. A total of 57 studies were identified. Triggers of awe were primarily related to nature and cognitive processes centred on vastness and the need for accommodation. A range of outcomes associated with awe were identified including increased well-being, spiritual growth, and pro-environmental intent. The key findings from this review informed a cognitive behavioural model of awe. Such a cognitive behavioural model may inform the cultivation of awe for individual, community, or environmental well-being and experience design. Future research is required to validate the proposed model, proposed pathways, and utility.
Tweens: A Positive Psychology Family Intervention for Adolescents with Depression- or Anxiety-related Symptomatology

Published: August 2023

AbstractPositive psychology is the scientific study of human thoughts, feelings and behaviour that focuses on building resources rather than treating illness. The current pilot study utilised qualitative methods to explore an intervention, ‘Tweens’, based on proven methods from positive psychology. Tweens was designed to be suitable for adolescents aged 11–14, who experienced symptoms of depression, anxiety, or stress. A defining feature of Tweens is that it included both the afflicted children and their parents, and is the first study to examine a positive psychology family intervention for this target group. Using Constructive Grounded Theory, this study sought to determine what meaning, if any, the participants ascribed to Tweens and how they integrated the methods into their daily lives. The study also investigated why some participants did not find the intervention meaningful or effective. The results show that the experienced meaningfulness of Tweens can be divided into three main categories: (1) A sense of belonging or togetherness, (2) The utility of the tools that were taught, and (3) An increased mindsight and learning how to choose actions mindfully. The results are discussed in light of the broaden-and-build theory: when parents and children have shared knowledge and vocabulary for talking about well-being, supportive upward spirals occur. All the adolescents did not perceive the intervention as meaningful, and we discuss variations in depressiveness, problematic life circumstances and possible flaws in the intervention as possible reasons for this.
The relevance of domestic and foreign factors in driving Ghana’s business cycle
Authors: Ameyaw Emmanuel 
Published: August 2023

AbstractIt is commonly assumed that external shocks dominate economic fluctuations in least-developed countries (LDCs), particularly commodity-exporting LDCs. Nonetheless, the magnitude and extent of the impact of such shocks compared to other domestic drivers of the business cycle in these countries remain unclear. This study employs a business cycle accounting model to empirically explore the relative contributions of domestic and external factors to Ghana’s post-independence business cycle. Contrary to widely held beliefs, our results suggest that external factors do not exert a predominant influence on Ghana’s business cycle. Instead, Ghana’s business cycle is driven largely by productivity shocks (or efficiency wedges), with the 1980s recession being an exception (which was largely driven by investment wedges). Furthermore, we also show that it is better to capture Ghana’s 2011 oil boom as a productivity shock rather than a government spending or an external shock (as some have done) when building a model of economic fluctuations for Ghana’s economy for that episode of the business cycle. These results have important implications for building models of economic fluctuations for Ghana’s economy.
South African health sciences students’ perspectives on utilisation, constraints and future possibilities of mHealth and e-Learning

Published: August 2023

AbstractThe global COVID-19 pandemic has added considerable complexity to the education and training of health care professionals as well as patient care. Literature suggests that e-Learning and mobile health (mHealth) technologies have great potential, but research studies are sparse, especially in low- to middle-income countries. The paper presents South African health science students’ perceptions of the importance, relevance, constraints and future possibilities of e-Learning and mHealth. Students from five universities participated in a modified Delphi. The first phase of student focus groups and interviews (n = 5), established baseline experiences and perceptions of e-Learning and mHealth during and post-COVID-19. These findings informed the design of an online survey (n = 155) for the second phase of the study. The majority of students were familiar with e-Learning, less so with mHealth; however most believed both to be a beneficial complement to theoretical and clinical teaching. Reasons for an integrated Learning Management System (LMS), also known as virtual learning environments, include increased flexibility, access and enhanced learning; and issues of anxiety, reduced interactivity, an absence of context and a lack of discipline- or profession-specific features as reasons against. The perceived importance of particular features of e-Learning and mHealth tools were highlighted. These findings will contribute to the redesign of online work-integrated curricula and the development of an inclusive, student-centred, health sciences-specific integrated and multi-modal LMS directed towards student-centred learning while addressing concerns around the digital divide and social justice.
Motivational and emotional states in self-directed language learning: a longitudinal study

Published: August 2023

AbstractThe current longitudinal case study investigated emotional and motivational states in a self-directed and mobile-assisted language learning environment. The participant of the study was a highly motivated language learner who used the Busuu application for a period of one year to learn German. Tracing the participant’s emotional and motivational journey using solicited diaries and chat-based interviews, the study revealed that the process of self-directed language learning is associated with the experience of a variety of positive and negative emotions. Joy, hope, and interest were the prevailing positive emotions that were linked to learning vocabulary; and frustration, anger, and feeling annoyed were the negative emotions in relation to learning grammar and pronunciation. In general, the study found a strong connection between positive emotions and persistence in self-directed language learning. The findings also pointed to some possible causes of high dropouts in application based language learning, as lack of enough resources for learning some language skills (such as grammar) initiated and implicated extensive processes of negative emotions. The study contributes to the growing body of knowledge in mobile-assisted language learning, and calls for further research regarding the role of emotions in technology-based and self-directed learning environments.

Abstract
Risk of bias assessment is a critical step of any meta-analysis or systematic review. Given the low sample count of many microbiome studies, especially observational or cohort studies involving human subjects, many microbiome studies have low power. This increases the importance of performing meta-analysis and systematic review for microbiome research in order to enhance the relevance and applicability of microbiome results. This work proposes a method based on the ROBINS-I tool to systematically consider sources of bias in microbiome research seeking to perform meta-analysis or systematic review for microbiome studies.
Vine-workers of the Lord: a Reading of the Runic Sequence and Imagery of the Tollemache Orosius Flyleaf
Authors: Birkett Tom 
Published: August 2023

ABSTRACTThe flyleaf to the Tollemache Orosius (London, British Library, Add. MS 47967, 1r) which includes a vine-scroll panel, symbols of the four evangelists, and several smaller notes and sketches, constitutes one of the most extensive sequences of manuscript marginalia to survive from Early Medieval England. Its iconographical complexity is compounded by the inclusion of a sequence of sixteen runes that has long puzzled runologists. This article offers a contextual interpretation of the Tollemache Orosius runic sequence informed by the wider corpus of English runica manuscripta and the particular iconographical, literary and manuscript context in which the runic note appears. Elucidating the link between the runes and the surrounding imagery helps to unravel the iconographical scheme of the flyleaf, centred on the Vineyard of the Lord. It also provides an insight into the reception of the Old English Orosius in late-tenth-century Winchester and the importance of the layered meaning of the vinea domini motif for both monastic communities and the secular church.
Mainstreaming the populist radical right? Online news exposure and voting behavior in the 2019 European Parliament election
Authors: Stier Sebastian , Froio Caterina , Ho Justin 
Published: August 2023

AbstractHow does media exposure relate to support for radical right populist parties (RRPPs)? We contribute to this classic debate by analyzing the web browsing histories and survey responses of six thousand study participants in France, Germany, Italy, Spain, and the UK during the 2019 European Parliament election. Linking direct measures of online news exposure to voting behavior allows us to assess the effects of the salience of issues politicized by RRPPs on their electoral support. The likelihood to vote for RRPPs was higher when the EU was more salient in individual media diets, while exposure to the less salient issue of immigration did not increase the propensity to vote for RRPPs. Alongside consistent results for other party families and interactions with pre-existing voting intentions, the findings indicate that the electoral effects of online media are contingent on the overall salience of a specific issue and voters’ predispositions.
Bottom‐Current Variability and the Relationship With Topography and Sedimentary Processes in the Drake Passage

Published: August 2023

AbstractBottom‐current related sediments have been commonly used for paleoceanographic reconstructions. However, the strength and variability of bottom currents are poorly understood and thus the processes that control sedimentation in deep environments are not clear. In this study, we focus on the Drake Passage, which is connected to the Antarctic Circumpolar Current, that has a major impact on the global climate. We studied the intensity and variability of bottom currents and how they are related to sedimentary processes. For this purpose, we used 27‐years from GLORYS12 Mercator Ocean reanalysis at high resolution to evaluate the bottom current dynamics. Geophysical data and surface grain size measurements were used to identify the type of sediment deposits. Our results show that the dynamics of bottom currents is disconnected from the sea surface dynamics, and bottom circulation is strongly controlled by the rough topography of the Drake Passage. The patterns for the first modes of bottom‐current variability are related to the local topography and seem to generally control the distribution of contourites. The second and third EOF modes show patterns in the bottom currents that differ from the mean field, and they may affect the rate of erosion and deposition differently. Time series of bottom currents reveals multiple high‐speed current events, but contourite drifts seem to accumulate preferentially in zones of slow and stable bottom currents. Our study highlights the potential of using ocean reanalysis to better constrain bottom currents in zones of scarce data and to plan future campaigns of direct measurements.

AbstractMigrating tides dominate the tropical climate on Mars and are known to reach high amplitudes during global dust events (GDE). In this study, we characterize the amplitude, phase and vertical wavelength of the diurnal and semidiurnal migrating tides in Mars' lower atmosphere (up to 50 km) by exploiting temperature vertical profiles retrieved from TIRVIM, an infrared spectrometer onboard the ExoMars Trace Gas Orbiter covering multiple local times. Observations from the Mars Climate Sounder onboard the Mars Reconnaissance Orbiter are used to complement the local time coverage when needed, and to estimate a seasonal trend to subtract from TIRVIM observations. We focus on two time periods in Martian Year 34, near Ls = 150° and near Ls = 200° (during the 2018 GDE). The characteristics of the migrating tides at Ls = 150° agree very well with tidal theory: a downward propagation, amplitudes of typically 2–5 K, and a larger vertical wavelength for the semidiurnal compared to the diurnal mode. Comparisons with model predictions from the Mars Planetary Climate Model reveal an excellent agreement, except for a slightly different phase of the diurnal tide. During the GDE, the tide pattern changes spectacularly: the diurnal tide amplitude reaches 35 K at 65°S and 17 K at 50°N, being vertically trapped up to 10 Pa. The semidiurnal tide is maximum near 20–30°S with an amplitude of 8–12 K. The phase of this mode is tilted with latitude, which was not the case before the storm. This indicates a significant contribution of the asymmetric Hough modes due to hemispheric asymmetry in the dust distribution.

AbstractMYD88 is the key signaling adaptor-protein for Toll-like and interleukin-1 receptors. A somatic L265P mutation within the Toll/interleukin-1 receptor (TIR) domain of MYD88 is found in 90% of Waldenström macroglobulinemia cases and in a significant subset of diffuse large B-cell lymphomas. MYD88-L265P strongly promotes NF-κB pathway activation, JAK-STAT signaling and lymphoma cell survival. Previous studies have identified other residues of the TIR-domain crucially involved in NF-κB activation, including serine 257 (S257), indicating a potentially important physiological role in the regulation of MYD88 activation. Here, we demonstrate that MYD88 S257 is phosphorylated in B-cell lymphoma cells and that this phosphorylation is required for optimal TLR-induced NF-κB activation. Furthermore, we demonstrate that a phosphomimetic MYD88-S257D mutant promotes MYD88 aggregation, IRAK1 phosphorylation, NF-κB activation and cell growth to a similar extent as the oncogenic L265P mutant. Lastly, we show that expression of MYD88-S257D can rescue cell growth upon silencing of endogenous MYD88-L265P expression in lymphoma cells addicted to oncogenic MYD88 signaling. Our data suggest that the L265P mutation promotes TIR domain homodimerization and NF-κB activation by copying the effect of MY88 phosphorylation at S257, thus providing novel insights into the molecular mechanism underlying the oncogenic activity of MYD88-L265P in B-cell malignancies.

AbstractOsimertinib is a promising approved third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) for treating patients with lung adenocarcinoma (LUAD) harboring EGFR-activating mutations, however, almost all patients develop resistance to Osimertinib eventually limiting the long-term efficacy. Autophagy is a vital cellular recycling process promoting Osimertinib resistance. Identifying accurate and efficient autophagy-regulatory factors is of great significance in reducing Osimertinib resistance. This study identified Cezanne, a member of the ovarian tumor protease (OTU)-deubiquitinating family, as an autophagy regulator. Cezanne was highly expressed in Osimertinib-resistant cells, and Cezanne overexpression promoted Osimertinib resistance, while chloroquine (CQ), an autophagy inhibitor, reverted this process. In the Cezanne-overexpressing cells, autophagy was activated even in the absence of autophagy inducers rapamycin and Earle’s Balanced Salt Solution (EBSS). Further study showed that Cezanne stabilized PIK3C3 by deubiquitinating K48-linked ubiquitination at Lysine 322. Surprisingly, as a compensatory mechanism of PI3P generation, PIK3C2A was shown to be upregulated by Cezanne by promoting its transcription in a POLR2A-dependent way. Based on these results, Cezanne also accelerates EGFR recycling which may explain the mechanism mediating Cezanne expression and Osimertinib resistance. In conclusion, this study establishes a new model connecting Cezanne, autophagy, and Osimertinib resistance, opening new avenues to explore the effect of Cezanne and autophagy in LUAD.

Published: August 2023

AbstractDroplets residing on textured oil-impregnated surfaces form a wetting ridge due to the imbalance of interfacial forces at the contact line, leading to a wealth of phenomena not seen on traditional lotus-leaf-inspired non-wetting surfaces. Here, we show that the wetting ridge leads to long-range attraction between millimeter-sized droplets, which coalesce in three distinct stages: droplet attraction, lubricant draining, and droplet merging. Our experiments and model show that the magnitude of the velocity and acceleration at which droplets approach each other horizontally is the same as the vertical oil rise velocity and acceleration in the wetting ridge. Moreover, the droplet coalescence mechanism can be modeled using the classical mass-spring system. The insights gained from this work will inform future fundamental studies on remote droplet interaction on textured oil-impregnated surfaces for optimizing water harvesting and condensation heat transfer.
