AbstractLead mixed‐halide perovskites offer tunable bandgaps for optoelectronic applications, but illumination‐induced phase segregation can quickly lead to changes in their crystal structure, bandgaps, and optoelectronic properties, especially for the Br–I mixed system because CsPbI3 tends to form a non‐perovskite phase under ambient conditions. These behaviors can impact their performance in practical applications. By embedding such mixed‐halide perovskites in a glassy metal‐organic framework, a family of stable nanocomposites with tunable emission is created. Combining cathodoluminescence with elemental mapping under a transmission electron microscope, this research identifies a direct relationship between the halide composition and emission energy at the nanoscale. The composite effectively inhibits halide ion migration, and consequently, phase segregation even under high‐energy illumination. The detailed mechanism, studied using a combination of spectroscopic characterizations and theoretical modeling, shows that the interfacial binding, instead of the nanoconfinement effect, is the main contributor to the inhibition of phase segregation. These findings pave the way to suppress the phase segregation in mixed‐halide perovskites toward stable and high‐performance optoelectronics.

AbstractBiCuSeO oxyselenides possess a highlighted thermoelectric performance among oxides, which originates from their intrinsically low thermal conductivity. However, intrinsic factors causing low thermal transport are also detrimental to carrier transport, leading to ultralow carrier mobility and relatively low electrical transport properties. Here, high‐conductivity single‐wall carbon nanotubes (SWCNTs) are adopted as the charge channels to be embedded in a BiCuSeO‐based matrix, providing a transport pathway for charge carriers. The results show that carrier mobility is increased to 188 cm2 V−1 s−1 due to the SWCNTs composited, triggering an enhancement in electrical transport properties. Besides, the SWCNTs embedded in the matrix introduce abundant interfaces, suppressing phonon transport and depressing lattice thermal conductivity. With these achievements, a maximum zT of 0.84 at 818 K is realized in the composite with 0.1 wt% SWCNTs. The mechanical property of the composites is strengthened as well because of the SWCNTs. The work indicates that the SWCNTs, as the charge channels, propose an effective approach for enhancing carrier mobility in BiCuSeO‐based materials, finally optimizing the thermoelectric performance as well as the mechanical property.

AbstractBackgroundFish in aquatic environments are end consumers of the food chain and are widely used for the evolution effects of environmental pollution and their interactions in aquatic ecosystem.ObjectiveIn the present study, common carp (Cyprinus carpio) fingerlings were selected to assess the potential risk and aquatic toxicity of meloxicam as a non‐steroidal anti‐inflammatory and a commonly used pharmaceutical drug.MethodsIn order to evaluate meloxicam toxicological effect on haematological, antioxidant status, enzymological and histological parameters, based on its LC50 24 h acute toxicity (10.05 mg L−1), fish fingerlings were exposed to four doses of meloxicam including; 0 (control), 0.1 (low), 1 (medium) and 2 mg L−1 (high) under static bioassay method for 28 days.ResultsThe results showed that sublethal doses of meloxicam significantly decreased alanine aminotransferase, alkaline phosphatase, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) levels in comparison with the control group after 28 days (p < 0.05). However, red blood cell, haematocrit, haemoglobin and malondialdehyde values in fish exposed to meloxicam significantly increased alongside its concentration (p < 0.05) more than the control group after 28 days. SOD, CAT and GPX mRNA expression levels in gill, liver, kidney and brain organ of fish under meloxicam treatment were significantly down‐regulated compared to the control group (p < 0.05). Histopathological assessment showed the increased vacuolation in hepatocytes in liver of fish exposure to medium and high doses of meloxicam.ConclusionIn conclusion, meloxicam induces oxidative stress in common carp which results a disruption of physiological and health status of this species based on our current findings.

Published: August 2023

AbstractA 1‐year 5‐month‐old, female, entire Parson Russell terrier was referred for investigations of focal epileptic seizures and behavioural changes. The clinical signs started 4 days after whelping its first litter. On presentation, the neurological examination was unremarkable. Neuroanatomical localisation was the forebrain. A brain magnetic resonance imaging showed bilateral, asymmetric, intra‐axial, T2‐weighted and fluid‐attenuated inversion recovery hyperintense, T1‐weighted hypointense, mildly to non‐contrast‐enhancing lesions in the piriform cortex. Cerebrospinal fluid analysis was within normal limits, and main infectious diseases were ruled out. Based on the presentation, findings and progression of clinical signs, a meningoencephalitis of unknown origin was suspected. In the present case, a positive response to immunosuppressive medication was observed. A well‐established link between pregnancy and immune‐mediated diseases, including meningoencephalitis, has been described in humans. This connection could have been the reason of the clinical signs, and this is supported by the recent pregnancy, presentation and positive response to immunosuppressive medication.
Living virus‐based nanohybrids for biomedical applications
Authors: Jin Lulu , Mao Zhengwei 
Published: August 2023

AbstractLiving viruses characterized by distinctive biological functions including specific targeting, gene invasion, immune modulation, and so forth have been receiving intensive attention from researchers worldwide owing to their promising potential for producing numerous theranostic modalities against diverse pathological conditions. Nevertheless, concerns during applications, such as rapid immune clearance, altering immune activation modes, insufficient gene transduction efficiency, and so forth, highlight the crucial issues of excessive therapeutic doses and the associated biosafety risks. To address these concerns, synthetic nanomaterials featuring unique physical/chemical properties are frequently exploited as efficient drug delivery vehicles or treatments in biomedical domains. By constant endeavor, researchers nowadays can create adaptable living virus‐based nanohybrids (LVN) that not only overcome the limitations of virotherapy, but also combine the benefits of natural substances and nanotechnology to produce novel and promising therapeutic and diagnostic agents. In this review, we discuss the fundamental physiochemical properties of the viruses, and briefly outline the basic construction methodologies of LVN. We then emphasize their distinct diagnostic and therapeutic performances for various diseases. Furthermore, we survey the foreseeable challenges and future perspectives in this interdisciplinary area to offer insights.This article is categorized under:

Scanning macro x‐ray fluorescence spectroscopy maps for matching 17th century paintings color areas to different earth pigments uses and for investigating attribution issues
Authors: Colombo Marco , Münch Falk , Hoffmann Peter , Sander Jochen , Ensinger Wolfgang 
Published: August 2023

AbstractFe and/or Mn‐containing yellow ochre, red ochre, and umber earth pigments are omnipresent in 17th century paintings. Less common in the materials used in historical paintings of this period is the Fe and Mn‐rich earth pigment sienna. Different uses of historical pigments in one painting by Georg Flegel (1566–1638) and another version of the same painting but of disputed attribution were recently uncovered by means of macro‐x‐ray fluorescence (MA‐XRF) scanning and other non‐invasive analytical techniques. In this paper, an approach solely based upon the correlation of Fe and Mn MA‐XRF maps with the optical image of the painting is compared to the use of Mn/Fe correlation plots. The identification of clusters within a plot of the Fe counts vs. the Mn counts can aid to infer whether an area with a certain color matches with the use of the earth pigments found in the two paintings and to ultimately shed light on the different usage of these pigments. The analytical thresholds found in the Mn/Fe correlation plots allowed to identify clusters differing in composition, which matched an area of a certain color with the earth pigments used therein. This highlighted the differences and similarities between the two paintings, ultimately ascertaining the lower value of the painting of disputed attribution. The analysis of single‐pixel spectra allowed refining the interpretation of specific Mn/Fe correlation plots. The purpose of these data evaluation steps is presented and the limitations of the proposed methodology are also discussed.

The Mediterranean Migration System
Authors: Doignon Yoann , Blöss-Widmer Isabelle , Ambrosetti Elena , Oliveau Sébastien 
Published: August 2023

AbstractTogether with the border between the US and Mexico, the Mediterranean is the largest migration area in the world. The stock of migrants resident in the Mediterranean countries was 42.6 million in 2020. About 2/3 of these international migrants are found in 4 countries (France, Spain, Italy, Turkey) and 20% in the rest of the Near East (Jordan, Lebanon, Israel, Syria, Palestine). The absolute number of these international migrants can vary greatly from one country to another; the migrants can thus represent a significant share of the overall population. The Mediterranean Basin has been historically characterised by a regular circulation of people within the region. The period after World War II till today (1948–2022) has been characterised by several changes in the Mediterranean migration system, which were largely driven by economic and political factors. Through a chronological approach, we can identify five periods that synthetise the evolution of migration in the Mediterranean region during this period.
(Re)theorisation of More-Than-Parental Involvement: New Directions and Hopes
Authors: Sadownik Alicja R. , Višnjić Jevtić Adrijana 
Published: August 2023

AbstractWhen engaging in the re-theorisation of parental involvement (PI), we searched for theories that would (1) embrace more-than-parents as potential collaboration partners, (2) recognise the role of the family in the child’s (educational) life, and (3) allow for the possibility of overcoming the “democratic deficit” (Van Laere et al., Eur Early Childhood Educ Res J 26(2):187–200. , 2018, p. 189), by which we mean the possibilities for families to co-create the modalities of their engagement with ECEC settings. The literature review presented in Chap. 2 mapped out the theories employed in research on PI and showed that those theories and models born out of interpretivist aims (i.e. to understand) and critical objectives (i.e. to challenge unjust power relations) have the potential to capture the increasing diversity of families and embrace the unfolding modalities of their engagement in diverse social, cultural, and material contexts. Based on the review, particular theories were chosen and explored in later chapters of this book. In this concluding chapter, we provide a theoretical overview by pointing to new directions for the theoretisation of more-than-parental involvement that are relevant to the ECEC field and the creation of sustainable futures.
Mapping the Theoretical Landscape of More-Than-Parental Involvement
Authors: Sadownik Alicja R. 
Published: August 2023

AbstractThis chapter presents an overview of the conceptual toolkits used to theorise relationships between ECEC settings and families in academic journal articles, published in English, between the years 2000–2010 and 2021–2022. The reconstructed overview of the theories employed by researchers from different regions of the world creates a base for classification of the theories aspositivistic(i.e., interested in measuring PI for prediction and control of academic achievement),interpretative(i.e., aiming at deeper contextual understandings of the perspectives of all social actors that have a part PI), orcritical(i.e., delving into the socio-economic conditions and power relations constituting diverse understandings of the world of PI, in conjunction with the desire for change). The chapter concludes with an outline of the theories discussed in further chapters, which are of an interpretive and critical nature and embrace the understanding of more-than-parental involvement presented in Chap.1.
Bronfenbrenner: Ecology of Human Development in Ecology of Collaboration
Authors: Sadownik Alicja R. 
Published: August 2023

AbstractThis chapter begins with a short presentation of the historical and biographical context of Bronfenbrenner’s research, which is followed by a description of his theory of an ecology of human development. This idea is presented both as a theory of child development and a theory of collaboration, as it is often the latter form that is applied in research on cooperation between early childhood education and care (ECEC) and parents/caregivers. The discussion addresses the ways in which Bronfenbrenner’s theory is currently applied in research on ECEC-family cooperation. In concluding remarks, the applications of the theory in relation to the understanding of more-than-parental involvement are presented in Chap. 1.
Collaboration Theory: ECEC Leading Families to Lead Their Own Partnerships with ECEC
Authors: Višnjić Jevtić Adrijana 
Published: August 2023

AbstractThis chapter gathers collaboration theories together into a discussion of how a partnership between ECEC and families is possible. It starts with a description of such a partnership, followed by the presentation of the collaboration theory. The emerging question of what constitutes a leader and a follower in the partnership between ECEC and families is answered with the help of the concept of pedagogical leadership and an empirical example of ECEC’s work with migrant and refugee children in the United States. The chapter concludes with an outline of ECEC’s responsibility for guiding parents to become leaders of the ECEC-home collaboration.
Parental Involvement (Mis)recognised by Bourdieu’s Conceptual Toolkit: Illusio, Doxa, Habitus, and Capitals
Authors: Sadownik Alicja R. 
Published: August 2023

AbstractThis chapter presents Bourdieu’s theoretical toolkit, which allows to look at the early childhood education and care (ECEC) settings’ collaboration with families through concepts embracing both objective/societal conditions and individual characteristics. These concepts are illusio, doxa, habitus, and capital. The empirical example presented in the chapter shows how the power of the parents’ economic, cultural, and social capital can negotiate and tailor the modes of involvement into parental needs and illusios. The analytical potential of Bourdieu’s theory is also discussed in relation to the established pre-school and social pedagogy traditions, which imply different practices of parental involvement.
Finite charges from the bulk action
Authors: McNees Robert , Zwikel Céline 
Published: August 2023

Abstract
Constructing charges in the covariant phase space formalism often leads to formally divergent expressions, even when the fields satisfy physically acceptable fall-off conditions. These expressions can be rendered finite by corner ambiguities in the definition of the presymplectic potential, which in some cases may be motivated by arguments involving boundary Lagrangians. We show that the necessary corner terms are already present in the variation of the bulk action and can be extracted in a straightforward way. Once these corner terms are included in the presymplectic potential, charges derived from an associated codimension-2 form are automatically finite. We illustrate the procedure with examples in two and three dimensions, working in Bondi gauge and obtaining integrable charges. As a by-product, actions are derived for these theories that admit a well-defined variational principle when the fields satisfy boundary conditions on a timelike surface with corners. An interesting feature of our analysis is that the fields are not required to be fully on-shell.
Tree-level UV completions for NRSMEFT d = 6 and d = 7 operators
Authors: Beltrán Rebeca , Cepedello Ricardo , Hirsch Martin 
Published: August 2023

Abstract
We study ultra-violet completions for operators in standard model effective field theory extended with right-handed neutrinos (NRSMEFT). Using a diagrammatic method, we generate systematically lists of possible tree-level completions involving scalars, fermions or vectors for all operators at d = 6 and d = 7, which contain at least one right-handed neutrino. We compare our lists of possible UV models to the ones found for pure SMEFT. We also discuss how the observation of LNV processes via NRSMEFT operators at the LHC can be related to Majorana neutrino masses of the standard model neutrinos.
Variance–covariance analysis of two high-resolution regional least-squares quasi-geoid models
Authors: Klees R. , Slobbe D. C. 
Published: August 2023

AbstractThis paper investigates the full variance–covariance (VC) matrix of two high-resolution regional quasi-geoid models, utilizing a spherical radial basis function parameterization. Model parameters were estimated using weighted least-squares techniques and variance component estimation (VCE) for data weighting. The first model, known as the “RCR model,” is computed through the remove–compute–restore method, incorporating various local gravity and radar altimeter datasets. The second model, the “combined model,” includes the GOCO05s satellite-only global geopotential model as an additional dataset with a full-noise VC matrix. Validation of the noise VC matrix scaling for each quasi-geoid model is achieved by comparing observed and formal noise standard deviations of differences between geometric and gravimetric height anomalies at GPS height markers in the Netherlands. Analysis of the noise VC matrix of height anomalies at grid nodes reveals significantly smaller formal noise standard deviations for the RCR model compared to the combined model. This difference is attributed to VCE assigning larger weights to the GOCO05s dataset, which exhibits greater noise standard deviations for the specific spatial scales used. Additionally, the formal noise standard deviations of height anomaly differences, relevant for GNSS-heighting, favor the RCR model. However, the disparity between the two models is smaller than implied by the height anomaly noise standard deviations. This is due to the combined model’s noise autocorrelation function displaying a longer correlation length (67 km) in contrast to the RCR model’s (17 km). Consequently, the combined model exhibits a greater reduction in noise variance for height anomaly differences relative to white noise compared to the RCR model.

AbstractExposure to multiple substances is a challenge for risk evaluation. Currently, there is an ongoing debate if generic “mixture assessment/allocation factors” (MAF) should be introduced to increase public health protection. Here, we explore concepts of mixture toxicity and the potential influence of mixture regulation concepts for human health protection. Based on this analysis, we provide recommendations for research and risk assessment. One of the concepts of mixture toxicity is additivity. Substances may act additively by affecting the same molecular mechanism within a common target cell, for example, dioxin-like substances. In a second concept, an “enhancer substance” may act by increasing the target site concentration and aggravating the adverse effect of a “driver substance”. For both concepts, adequate risk management of individual substances can reliably prevent adverse effects to humans. Furthermore, we discuss the hypothesis that the large number of substances to which humans are exposed at very low and individually safe doses may interact to cause adverse effects. This commentary identifies knowledge gaps, such as the lack of a comprehensive overview of substances regulated under different silos, including food, environmentally and occupationally relevant substances, the absence of reliable human exposure data and the missing accessibility of ratios of current human exposure to threshold values, which are considered safe for individual substances. Moreover, a comprehensive overview of the molecular mechanisms and most susceptible target cells is required. We conclude that, currently, there is no scientific evidence supporting the need for a generic MAF. Rather, we recommend taking more specific measures, which focus on compounds with relatively small ratios between human exposure and doses, at which adverse effects can be expected.
