Amphipod samples were collected from the rocky habitat of Arjyapalli beach in southern Odisha, India. The specimens were analysed for morphological characters. One interesting species was observed during the study and was identified as Stenothoe lowryi. The species was previously reported only from Malaysia. The present study confirms the distributional range extension of this species to Indian waters and details a few additional morphological characters.

This article examines the Italian translations and reception of Winston S. Churchill’s The Second World War, using British and Italian archival materials and press sources. It shows how the Italian editions and serialisations introduced constant modifications – abridgements, omissions, textual cuts, and paratextual framing – in order to adapt the memoirs for a national audience. These interventions softened Churchill’s judgments on Italy, emphasised the ideological character of the war, and strengthened anti-Soviet themes, thus aligning the text with dominant cultural and political discourses of the postwar years. Analysis of contemporary reviews and newspaper debates highlights a polarised reception: critical distance or silence in intellectual journals contrasted with enthusiastic praise in mainstream dailies, where the memoirs were hailed as both literary achievement and democratic statement. The article argues that these editorial and translational strategies played a crucial role in integrating Churchill’s narrative into Italian collective memory, supporting a symbolic redefinition of Italy’s place from defeated nation to one of the victors.

Popular music culture has often featured in postwar British history as a site of tolerance and inclusivity, of multicultural exchange and anti-racist activism. This article, while not denying music's intersections with progressive causes, presents a different narrative. I use the pages of Britain's most prominent weekly music paper, the New Musical Express (NME), to demonstrate the important role that music has played in perpetuating wider processes of racialization in the late twentieth century. Surveying contestations over race in the mid-1980s and early 1990s, it highlights the ways in which popular music institutions such as the NME could function as sites of racial formation, reproducing the social power of whiteness even when providing space for what was often referred to as “black music.” The article underlines the degree to which popular music could produce hegemonically white cultural spaces, despite the diversity of musical culture at large. In so doing, it indicates the significance of popular culture for understanding patterns of racialization into the latter years of the twentieth century and beyond.

Authorship metrics are a key component of academic advancement. Given recent increases in the publication of collaborative, multiauthored articles, we examine patterns in the perceived gender of authors of peer-reviewed journal articles with five or more coauthors in 11 academic archaeology journals. Our results suggest consistent patterns in lead and last authors and in coauthors. Men are more likely to serve as both lead and last authors and to include far more men than women as coauthors on their publications. We consider the ways gender homophily, friendship networks, and other forms of often unintentional exclusion may have a negative impact on the careers of women and members of other marginalized communities in archaeology and propose recommendations to address these issues within the field. In addition to greater individual reflexivity around coauthorship decisions, we encourage the development of clear guidelines on author ascription by archaeological organizations and publishing outlets and advocate that institutions adopt both total publication and fractional publication counts as measures of individual productivity.

Predictive maintenance in safety-critical systems like turbofan engines increasingly relies on machine learning (ML) models to estimate remaining useful life (RUL), but the ‘black box’ nature of these models hinders their adoption and trustworthiness. While traditional ex-ante prognostic metrics (e.g. monotonicity, trendability) are used to pre-screen sensor data, a systematic comparison against the post-hoc explanations of what a model actually learns is lacking. We explore the application of SHapley Additive exPlanations (SHAP) from explainable artificial intelligence (XAI) to investigate feature importance in engine failure prediction using the second dataset of the Commercial Modular Aero-Propulsion System Simulation (CMAPSS). The preprocessing pipeline includes z-score normalisation of sensor data and the calculation of a health index (HI) to quantify system degradation. A power-law fit is applied to the HI to capture the underlying trends of engine wear and failure progression. We use the normalisation data to calculate prognostic feature selection metrics: monotonicity, trendability and prognosability. Then, we train two machine learning models – random forest (RF) regressor and gradient boosting (GB) method – directly from the raw data to predict the RUL based on the actual sensor readings. The SHAP values generated for both models are analysed to identify the features with the most significant impact on RUL predictions. By comparing the SHAP value distributions across models and prognostic predictors, we highlight feature robustness and their relative influence on engine degradation and failure prediction. This work provides insights into the interpretability of machine learning models in prognostics and enhances the understanding of sensor contributions to engine health monitoring. The results demonstrate the effectiveness of SHAP in elucidating feature importance, supporting the development of more transparent and reliable prognostic systems.

This text explores how electronic musical instruments and electronic music ensembles can relate to composition and music notation by discussing the instruments in terms of existing practice in traditional instrumentation and in relation to symbolic electroacoustic music analysis. Starting from orchestration theory, the text considers how electronic musical instruments behave and are used, both with support from the author’s own practice and from a case study with students within the framework of a live-electronic ensemble course. The case study reflected the participants’ practice as creative composers/musicians, and how their exploratory and experimental approaches to their instruments proved important, creating challenges for notation. Traditionally, music notation relies on continuous changes of simple parameters, while performances with complex electronic instruments may have just as important information to document regarding their initial connectivity and parameter settings.

Human rights have served as a central normative framework for global health law, with the World Health Organization (WHO) providing an institutional foundation to implement human rights law through global health governance. In implementing human rights obligations, WHO has sought to bring human rights into its normative standard-setting to promote health equity—within and between countries. Yet, WHO faced challenges in realizing human rights to ensure equity in the COVID-19 response, as its member states violated individual rights and undermined global solidarity. Despite this imperative to strengthen human rights as a foundation for global health equity, recent reforms have failed to advance human rights meaningfully in global health law, as WHO member states weakened necessary human rights provisions. This essay examines new opportunities to strengthen human rights in global health, ensuring systemic integration across international legal regimes and human rights operationalization in the implementation of global health law.

The far right is becoming increasingly established worldwide and is now in its ‘fourth wave’, characterised by its mainstreaming and normalisation. Although more and more political science research focuses on these processes, we argue that this literature lacks conceptual clarity about what these terms mean, which actors are involved, and what effects these processes have. This article has two aims. First, we describe how mainstreaming and normalisation have been conceptualised and analysed in the existing literature. Building on this, we then introduce a conceptual framework for future empirical research and discuss three research avenues: more precise operationalisations of the mainstream/normal and non-mainstream/abnormal, more refined theories about different political actors, and a broader analytical perspective beyond immigration issues and national-level dynamics.

Mountain permafrost is a climatically sensitive but poorly constrained component of the terrestrial cryosphere. We use 108 U-Th dates from speleothems in two limestone caves in the Uinta Mountains of northern Utah, USA, to reconstruct a 600,000 year history of permafrost presence and absence in this alpine setting. Speleothem growth in both caves is confined almost entirely to discrete intervals that align with interglacial conditions of Marine Isotope Stages (MIS) 5e, 7e, 9e, 11c, and 13. In contrast, growth hiatuses correspond to glacial periods, when permafrost apparently inhibited infiltration of liquid water. Regional lapse rates indicate that cooling of ∼3°C to 5°C relative to present would be sufficient to generate permafrost above the caves. The persistence of age clustering across multiple speleothems in two independent cave systems suggests that mountain permafrost repeatedly formed and degraded in concert with orbitally paced climate cycles. Comparison with nearby paleoclimate records confirms that these changes reflect regional-scale climate forcing. Our results provide rare empirical evidence for the extent of alpine permafrost over Quaternary timescales. As mountain permafrost degrades under modern warming, such records are essential for refining climate models, assessing geomorphic and hydrologic risks, and placing recent changes within the context of natural variability.

Ship path planning represents a fundamental challenge in intelligent navigation, requiring careful balance between route optimality, safety in complex marine environments. To address the limitations of conventional A* algorithms, this paper proposes an improved multi-factor and multi-scale A* algorithm. The methodology begins with processing ENC data, where canny edge detection combined with adaptive thresholding constructs obstacle maps. A novel dual-layer multi-scale grid framework is established: They are used to rapid global path searching, and precise collision avoidance. The algorithm innovatively integrates a multi-factor function that simultaneously considers obstacle distribution, environment effects, navigation rules, and ship dynamic constraints, with adaptive weight adjustment optimizing the search process. Path refinement employs smoothing algorithms to significantly reduce waypoint numbers. Simulation experiments conducted in Dalian port demonstrate the algorithm’s superior performance: maintaining safe clearance even in obstacle-dense areas and using the shorter length. Experimental results confirm that generated paths better satisfy practical navigation requirements.

Maternal nutrition is critical for foetal brain development, and dietary polyphenolic compounds play an important role in mitigating oxidative stress, inflammation, and neurotoxic damage. This narrative review explored the potential promotion of brain development by polyphenols such as resveratrol, curcumin, quercetin, naringin, ferulic acid, genistein, and fisetin through their antioxidant, anti-inflammatory, and neurotrophic effects. The key molecular mechanisms are central to the advantageous actions of these polyphenols in the neurogenesis process. These compounds protect against neurodevelopmental challenges induced by maternal high-fat diet, immune activation, environmental toxins, and psychological stressors. However, their efficacy may depend on dosage, timing of administration, and maternal-foetal metabolic interactions, emphasising the need for personalised maternal nutrition strategies. Further research is needed to investigate the long-term effects and interactions of these compounds with other nutrients toward personalised maternal nutrition strategies. This narrative review presents the potential of polyphenols to support foetal brain health with an emphasis on their possible incorporation into maternal dietary interventions.

Cylindrical vector (CV) $\gamma$ rays can introduce spatially structured polarization as a new degree of freedom for fundamental research and practical applications. However, their generation and control remain largely unexplored. Here, we put forward a novel method to generate CV $\gamma$ rays with tunable hybrid polarization via a rotating electron beam interacting with a solid foil. In this process, the beam generates a coherent transition radiation field and subsequently emits $\gamma$ rays through nonlinear Compton scattering. By manipulating the initial azimuthal momentum of the beam, the polarization angle of $\gamma$ rays relative to the transverse momentum can be controlled, yielding tunable hybrid CV polarization states. Three-dimensional spin-resolved particle-in-cell simulations demonstrate continuous tuning of the polarization angle across $\left(-90{}^{\circ},\ 90{}^{\circ}\right)$ with a high polarization degree exceeding 60%. Our work contributes to the development of structured $\gamma$ rays, potentially opening up new avenues in high-energy physics, nuclear science and laboratory astrophysics.

Micro- and nanoplastics (MNPs) pollution has become a global environmental concern due to its widespread presence and diverse sources. These tiny plastic particles, originating from industrial processes, plastic waste degradation, and consumer products, have infiltrated various ecosystems, food chains, and even human tissues. Recent studies indicate that MNPs are not only pervasive in air, water, and soil but also accumulate in the human body through ingestion, inhalation, and dermal exposure. However, the implications of MNPs exposure, particularly during pregnancy, remain poorly understood. Of critical concern is the potential transfer of MNPs and their associated chemical additives across the placental barrier, posing risks to fetal development. In this review, we comprehensively analyze mainstream technologies used for detecting and characterizing MNPs, including spectroscopy- and microscopy-based approaches, as well as emerging detection methods. We also examine recent findings on the toxicity of MNP-associated chemicals, such as endocrine-disrupting compounds and heavy metals, which may have long-term effects on human health. Particular emphasis is placed on how maternal exposure to MNPs could impact offspring development, potentially leading to neurodevelopmental disorders, metabolic disturbances, and immune system dysregulation. Despite growing concerns, research gaps persist regarding the precise mechanisms through which MNPs influence maternal and fetal health. The findings recommend for further multidisciplinary research to assess the long-term consequences of prenatal MNPs exposure. Addressing these uncertainties is crucial for informing public health policies, mitigating risks, and ensuring the well-being of pregnant women and future generations.
