Inspired by the theory of hyperbolic polynomials and Hodge theory, we develop the theory of Lorentzian polynomials on cones. This notion captures the Hodge-Riemann relations of degree zero and one. Motivated by fundamental properties of volume polynomials of Chow rings of simplicial fans, we define a class of multivariate polynomials which we call hereditary polynomials. We give a complete and easily checkable characterization of hereditary Lorentzian polynomials. This characterization is used to give elementary and simple proofs of the Heron-Rota-Welsh conjecture for the characteristic polynomial of a matroid, and the Alexandrov-Fenchel inequalities for convex bodies.

We then characterize Chow rings of simplicial fans which satisfy the Hodge-Riemann relations of degree zero and one, and we prove that this property only depends on the support of the fan.

Several different characterizations of Lorentzian polynomials on cones are provided.

The present study has set up a pilot experiment to optimise the most promising assays for investigating the survival of Antarctic microbial cryptoendolithic communities – a natural astrobiological benchmark – when subjected to lethal/sub-lethal stresses testing viability, cell integrity and metabolic activity. Namely, the viability tests for culturable species are based on cultivation on a solid medium, while qPCR coupled to propidium monoazide (PMA) provides information of both culturable and non-culturable microorganisms. The fluorescein diacetate (FDA) and Adenosine 5’-TriPhosphate (ATP) assays, here optimised, consent to highlight the presence of metabolically active cells. The results revealed significant differences between the treated and untreated samples, proving the suitability of the selected tests for investigating the resilience of these astrobiological models.

Marsupials have been the subject of experimental and natural parasitological studies on helminths in the Americas. Brazil has a significant proportion of the American marsupial fauna, with approximately 15 genera and 69 species out of 95 extant. Helminths have been reported for approximately one-third of the Brazilian marsupial species. Consequently, an update of this information is necessary to ensure the correct identification of the species. This work represents the first comprehensive review of the helminths of the Brazilian marsupials, including taxonomic information on both parasites and hosts. The data were extracted and compiled from references published from 1819 to 2023 and organised according to the classification of the helminths by the host name of the original description, followed by the updated host species nomenclature, geographical distribution, site of infection, and references. In total, 1,047 records of helminths parasitising 22 marsupial species in Brazil were compiled. The list included 93 identified species, including five of the phylum Acanthocephala, 58 of the phylum Nematoda, and 30 of the phylum Platyhelminthes. In addition, 51 other morphospecies were reported. This work may serve as a reference for future studies.

This study aims to understand if the American public supports five policies related to the involvement of healthcare providers in immigration enforcement efforts such as documenting legal status in medical charts to actively assisting immigration enforcement. We also seek to establish whether public attitudes are stable on this issue using an experiment highlighting the implications of these policies for immigrants, communities, and the broader public. To assess public attitudes, we fielded a survey (N = 6049) from 7 March to 26 March 2025. We randomly assigned respondents to one of six treatments highlighting various implications of these policies for immigrants and communities. We found a divided public on the topic, with a substantial number of Americans willing to blur the lines between immigration policy and the provision of healthcare. Respondents were most receptive to tracking the number of undocumented patients served and least supportive of assisting in detaining patients. We found substantial differences based on party affiliation and presidential vote choice but not personal connections or residence inside or outside of border states. Our findings suggest that a majority of Americans support some level of immigration enforcement in healthcare settings while public opinion on this issue is hard to move.

Over the history of Maya studies, archaeologists have proposed various models for the structure of Maya settlements and their use of the landscape. The introduction of lidar to Maya studies, and the wealth of data this technology yielded, has many of these ideas coming under renewed study. Some of the most prominent models discussed in the last two decades have centered on low-density agrarian urbanism and forest gardens. Using settlement studies, lidar data, and hydrological analysis, this article discusses the applicability of these models for the ancient Maya at Lamanai and Ka’kabish, and more generally, Northern Belize. The Maya in the periphery at Lamanai developed wetland management strategies by capitalizing on natural drainage next to seasonally inundated swamps, or bajos. Evidence suggests that the Maya sustained large populations by using channels at the edge of bajos for field systems. These systems may be key to understanding their sustainability in the past.

Professional burnout syndrome represents a significant occupational hazard within European primary care physicians, impacting their well-being, quality of care, and the sustainability of healthcare systems. This joint European Psychiatric Association (EPA) and the World Organization of National Colleges, Academies and Academic Associations of General Practitioners/Family Physicians- Europe Region (WONCA Europe) viewpoint focuses specifically on primary care physicians, contrasts their risk profile with other specialties, and outlines actionable, system-level recommendations for policymakers, provider organizations, and professional associations. Evidence indicates a wide range in professional burnout syndrome prevalence, influenced by assessment methodologies and specific national contexts. The syndrome manifests through emotional exhaustion, depersonalization, and reduced personal accomplishment, often accompanied by secondary psychological and physical symptoms. A multitude of interacting risk factors at the individual, interpersonal, and organizational levels contribute to its development. Effective mitigation strategies necessitate a multi-pronged approach encompassing individual coping mechanisms and systemic organizational changes aimed at alleviating workload, enhancing autonomy, and fostering supportive work environments.

This article explores how the five major rebellions which took place in Devon and Cornwall between 1485 and 1603 were subsequently remembered by the region’s inhabitants. It begins by demonstrating that – although early modern elites generally preferred to say as little as possible about episodes of popular protest once they had been safely suppressed – the revolts which had occurred under the Tudor monarchs went on to be officially memorialised in several South Western communities. The article then moves on to discuss how local gentlefolk looked back on the rebellions, and argues that such individuals tended, in their retrospective accounts, to exaggerate the degree of social radicalism which had been exhibited by the insurgents. Next, the article considers the few scraps of evidence which have survived about popular memories of the protests, and suggests that, while the specific grievances which had motivated the rebels may well have been quite quickly forgotten, the desperate courage with which they had fought – particularly during the Western Rising of 1549 – had continued to be remembered by the ordinary people of the region for decades to come. The fourth and last part of the article looks at ‘modern’ commemoration of the revolts and draws out some general conclusions.

This paper considers how issue salience environments affect long-term patterns of political choice via processes of political socialization. Drawing on the well-known ‘impressionable years’ hypothesis, we theorize that voters who grew up in high-immigration salience contexts subsequently exhibit higher levels of voter-party agreement on immigration (issue congruence). We find support for this hypothesis from two studies, which leverage cross-sectional variation within cohorts in exposure to immigration salience in voters’ formative years. The first employs congruence data from a survey of 10 European countries, linked to historical salience data from the Comparative Manifesto Project. The second is a within-country study, measuring salience and congruence from two long-running German public opinion survey series. The analysis suggests that growing up at times when immigration is high on the political agenda can have long-term consequences for the relationship between voters’ preferences on that issue and their political choices, shedding light on the mechanism behind ‘generational realignment’.

The discourse on decolonising environmental education necessitates a critical engagement with Indigenous epistemologies and narratives that challenge dominant, Eurocentric paradigms of ecological knowledge. Sheela Tomy’s Valli (2022) offers a compelling literary intervention in this context, concentrating forest narratives and subverting colonial legacies of environmental exploitation. The analysis positions Valli as a narrative intervention that centres the Adivasi communities of Kerala’s Wayanad district. The fiction portrays the forest as a sentient, sovereign entity, challenging colonial and post-colonial forest policies that commodified nature through timber extraction and plantations, leading to ecological ruin and displacement. Guided by the insights of decolonial theorists such as Walter Mignolo, Arturo Escobar and Vandana Shiva, the article demonstrates how the fiction leverages folklore and testimony to validate oral histories, presenting them as crucial for understanding ecological crises. Valli enacts a pedagogical project that recentres Indigenous knowledge, aligning with environmental justice movements. The article concludes that decolonising environmental education requires fundamental ontological shift from human domination to coexistence. It advocates for a pedagogical model, exemplified by the fictional Kadoram school, which integrates Indigenous knowledge, advances multispecies empathy and recognises the land as a co-instructor. This approach thereby fosters pluriversality and a sustainable environmental ethic.
