Unlabelled: The interconnecting links between individuals in an animal social network are often defined by discrete, directed behaviours, but where these are difficult to observe, a network link (edge) may instead be defined by individuals sharing a space at the same time, which can then be used to infer a social association. The method by which these associations are defined should be informed by the biological significance of edges, and therefore often vary between studies. Identifying an appropriate measure of association remains a challenge to behavioural ecologists.

Article Synopsis
  • Statins are often underutilized for preventing cardiovascular disease (CVD), and understanding factors influencing adherence is crucial.
  • This study aims to explore the connection between shared decision making (SDM)—reflected through recorded CVD risk scores—and patients' adherence to statins and overall health outcomes.
  • By analyzing data from English primary care records of patients aged 40-84 who started statin therapy, the research will assess how the presence of a CVD risk score at initiation impacts ongoing medication adherence and CVD-related results.

Article Synopsis
  • Ironmaking can contribute to a circular economy by using alternative carbon sources like biomass and plastic waste, which are often undervalued or disposed of.
  • A study explored how these carbon materials, particularly those with higher chlorine content, influence the production of harmful pollutants like dioxins and PCBs during the high-temperature processing of iron ore.
  • Findings revealed a direct link between chlorine levels in fuel and dioxin emissions, with biomass and PVC significantly increasing these emissions, especially plastics, while copper acted as a catalyst that affected the formation of specific dioxins.

Background: Postpartum uterine disease (metritis) is common in dairy cows. The disease develops within 1 week after calving and is associated with microbial dysbiosis, fever, and fetid uterine discharge. Cows with metritis have a greater likelihood of developing endometritis and infertility later postpartum.

Article Synopsis
  • - Fescue toxicosis and reproductive ergotism cause similar toxic effects in late-pregnant mares and potentially other equine species, stemming from ergopeptine alkaloids (EPAs) produced by fungi.
  • - These toxins originate from a harmful endophyte found in tall fescue and a nonendophytic fungus affecting grains and grasses.
  • - Symptoms of equine ergopeptine alkaloid toxicosis (EEPAT) include issues with milk production, prolonged pregnancies, and complications during birth, leading to challenges for both mares and their foals; prevention focuses on eliminating toxin exposure and addressing hormonal imbalances.

To create the next innovative product, participants in science need to understand which existing technologies can be combined, what new science must be discovered, and what new technologies must be invented. Knowledge of these often arrives by means of expert consensus or popularity metrics, masking key information on how intellectual efforts accumulate into technological progress. To address this shortcoming, we first present a method to establish a mathematical link between technological evolution and complex networks: a path of events that narrates innovation bottlenecks.

Boxelder and sycamore maple contain hypoglycin A (HGA), the toxic metabolite of which, MCPA-CoA, inhibits fatty acid β-oxidation, causing seasonal pasture myopathy (SPM) or atypical myopathy (AM), respectively. White snakeroot and rayless goldenrod contain multiple benzofuran ketones (BFKs). The identity/toxicity of BFKs appear variable, possibly involving interactions between toxins/toxic metabolites, but ultimately inhibit cellular energy metabolism.

The importance of seeing race as a socially constructed idea continues to produce unfair differences between humans and establishes power relations that lead to injustice and exposure to death. Since the racial justice movement in early 2020, there has been a heightened awareness of, and increased interest in, addressing historic racial disparities across Schools of Public Health (SPH) in Canada. Steps have been taken to recognize systemic racism and increase diversity through structural reforms to advance equity and inclusion; however, addressing racism demands collectively uprooting racist institutional designs still inherent in learning, teaching, research, service, and community engagement.

Animal sociality, an individual's propensity to associate with others, has fitness consequences through mate choice, for example, directly, by increasing the pool of prospective partners, and indirectly through increased survival, and individuals benefit from both. Annually, fitness consequences are realized through increased mating success and subsequent fecundity. However, it remains unknown whether these consequences translate to lifetime fitness.

Iron ores are principal input materials for iron and steel-making industries. Quality of iron ores is one of the critical parameters for formation of environmental pollutants related to the steel-making process. Dioxins are identified as one of the most toxic pollutants emitted during ironmaking, specifically during the sintering process.

This study investigated concentrations of PM, PM, SO, NO, CO and O, and air quality index (AQI) values across 368 cities in mainland China during 2015-2018. The study further examined relationships of air pollution status with local industrial capacities and vehicle possessions. Strong correlations were found between industrial capacities (coal, pig iron, crude steel and rolled steel) and air pollution levels.

We study the evolution of networks through 'triplets'-three-node graphlets. We develop a method to compute a transition matrix to describe the evolution of triplets in temporal networks. To identify the importance of higher-order interactions in the evolution of networks, we compare both artificial and real-world data to a model based on pairwise interactions only.

Metal production industries are associated with positive economic benefits, however their activities are significantly resource and energy intensive, contributing to emission of pollutants and greenhouse gases to the environment. The balance between the economic inputs and environmental footprint of the metal production industries determines their contribution to sustainability. This work provides environmental impact assessment of the production of aluminium, copper, gold, iron and steel, lead, nickel and zinc, and considers their contribution to the economy.

Four decades after the Declaration of Alma-Ata, its vision of health for all and strategy of primary health care are still an inspiration to many people. In this article we evaluate the current status of primary health care in the era of the Declaration of Astana, the sustainable development goals, universal health coverage and the coronavirus disease 2019 pandemic. We consider how best to guide greater application of the primary health care strategy, reflecting on tensions that remain between the political vision of primary health care and its implementation in countries.

This article addresses diagnostic challenges involving toxicology cases that are multifactorial in nature, often involving sublethal exposures to multiple toxicants and/or other etiologies that are not toxic. Gold standard diagnostic approaches were developed under the assumption that cases were undoubtedly intoxications, and they still are applicable to those cases. A more integrated diagnostic approach, focusing on the initial problem list, is consistent with how veterinarians diagnose most cases.

Atrial fibrillation (AF) is the most common cardiac arrhytmia, characterized by the chaotic motion of electrical wavefronts in the atria. In clinical practice, AF is classified under two primary categories: paroxysmal AF, short intermittent episodes separated by periods of normal electrical activity; and persistent AF, longer uninterrupted episodes of chaotic electrical activity. However, the precise reasons why AF in a given patient is paroxysmal or persistent is poorly understood.

The Price model, the directed version of the Barabási-Albert model, produces a growing directed acyclic graph. We look at variants of the model in which directed edges are added to the new vertex in one of two ways: using cumulative advantage (preferential attachment) choosing vertices in proportion to their degree, or with random attachment in which vertices are chosen uniformly at random. In such networks, the longest path is well defined and in some cases is known to be a better approximation to geodesics than the shortest path.
