    Abstract Aim: A major barrier to performing cardiac arrest trials is the requirement for prospective informed consent, which is often infeasible during individual medical emergencies. In an effort to improve outcomes, some governments have adopted legislation permitting research without prior consent (RWPC) in these circumstances. We aimed to outline key differences between legislation in four Western locations and explore the effects of these differences on trial design and implementation in cardiac arrest research.
    Data sources: We performed a narrative review of RWPC legislation in the United States (US), Canada, the European Union (EU) and the United Kingdom (UK).
    Results: The primary criteria required to perform RWPC was similar across locations: the study must involve an individual medical emergency during which neither the prospective subject nor their authorized representative can provide informed consent. The US regulations were unique in their requirements for performing Community Consultation and Public Disclosure in the communities in which the research takes place. Another major difference was the requirement for consent for ongoing participation in Canada, the EU and the UK, while only notification of enrollment and the opportunity to discontinue participation are required in the US. Additionally, only Canada and the EU explicitly state that the subject or their representative may request withdrawal of their data.
    Conclusion: Regulations governing RWPC in the US, Canada, the EU and the UK have similar goals and protections for vulnerable populations during medical emergencies. Differences in the qualifying criteria and implementation procedures exist across locations and may affect study design.

    Abstract Proline-rich antimicrobial peptides (PrAMPs) are promising candidates for the treatment of infections caused by high-priority human pathogens. Their mode of action consists of (I) passive diffusion across the outer membrane, (II) active transport through the inner membrane, and (III) inhibition of protein biosynthesis by blocking the exit tunnel of the 70S ribosome. We tested whether in vitro data on ribosomal binding and bacterial uptake could predict the antibacterial activity of PrAMPs against Gram-negative and Gram-positive bacteria. Ribosomal binding and bacterial uptake rates were measured for 47 derivatives of PrAMP Onc112 and compared to the minimal inhibitory concentrations (MIC) of each peptide. Ribosomal binding was evaluated for ribosome extracts from four Gram-negative bacteria. Bacterial uptake was assessed by quantifying each peptide in the supernatants of bacterial cultures. Oncocin analogues with a higher net positive charge appeared to be more active, although their ribosome binding and uptake rates were not necessarily better than for Onc112. The data suggest a complex mode of action influenced by further factors improving or reducing the antibacterial activity, including diffusion through membranes, transport mechanism, secondary targets, off-target binding, intracellular distribution, and membrane effects. Relying only on in vitro binding and uptake data may not be sufficient for the rational development of more active analogues.

    Abstract Simulations of snow-atmosphere interactions are often the domain of complex, modern atmospheric models. These models have assisted our understanding of the physical processes behind snow-atmosphere interactions and have demonstrated capability of simulating atmospheric processes which affect seasonal snow. However, computational limitations have limited the use of fully coupled snow-atmosphere models to case studies. The High-resolution Intermediate Complexity Atmospheric Research (HICAR) model presents a computationally efficient platform through which some snow-atmosphere process can be simulated at the hectometer scale and at seasonal time scales. In particular, ridge-scale snow depth patterns influenced by preferential deposition and leeside eddies are resolved by the model. This is done while still utilizing 804x fewer computational resources than the Weather Research and Forecasting (WRF) model. Here we present a validation of the HICAR model using snow depth data and distributed wind data collected during Winter 2022/2023 in complex terrain in the Swiss Alps. These results show that HICAR can downscale both winds and precipitation to within the same accuracy as WRF. Thus, HICAR offers the ability to dynamically downscale forcing data to the target resolution of snow model simulations or for detailed studies under future climate scenarios. To this point, results from a study using a one-way coupling strategy between HICAR and an intermediate complexity snow model with snow redistribution will also be presented, showing the importance of different accumulation processes across scales. Remaining challenges and caveats of this modeling strategy, including the representation of turbulent mixing and dependency on input data, will also be discussed.

    Abstract Sap exudation is the process whereby trees such as sugar (Acer saccharum Marsh.) and red maple (Acer rubrum L.) generate unusually high positive stem pressure in response to repeated cycles of freeze and thaw. This elevated xylem pressure permits the sap to be harvested over a period of several weeks and hence is a major factor in the viability of the maple syrup industry. The extensive literature on sap exudation documents competing hypotheses regarding the physical and biological mechanisms that drive positive pressure generation in maple, but to date, relatively little effort has been expended on devising mathematical models for the exudation process. In this paper, we utilize an existing model of Graf et al. (J Roy Soc Interface 12:20150665, 2015) that describes heat and mass transport within the multiphase gas-liquid-ice mixture in the porous xylem tissue. The model captures the inherent multiscale nature of xylem transport by including phase change and osmotic transport in wood cells on the microscale, which is coupled to heat transport through the tree stem on the macroscale. A parametric study based on simulations with synthetic temperature data identifies the model parameters that have greatest impact on stem pressure build-up. Measured daily temperature fluctuations are then used as model inputs and the resulting simulated pressures are compared directly with experimental measurements taken from mature red and sugar maple stems during the sap harvest season. The results demonstrate that our multiscale freeze-thaw model reproduces realistic exudation behavior, thereby providing novel insights into the specific physical mechanisms that dominate positive pressure generation in maple trees.

    Abstract The interplay between organisms with their abiotic environment may have profound effects within ecological networks, but are still poorly understood. Soil physical ecosystem engineers (EEs) modify the abiotic environment, thereby potentially affecting the distribution of other species, such as microarthropods. We focus on three co-occurring physical EEs (i.e. cattle, vegetation, macrodetritivore) known for their profound effect on soil properties (e.g. pore volume, microclimate, litter thickness). We determined their effects on Collembola community composition and life-form strategy (a proxy for vertical distribution in soil) in a European salt marsh. Soil cores were collected in grazed (compacted soil, under short and tall vegetation) and non-grazed areas (decompacted soil, under short and tall vegetation), their pore structure analysed using X-ray computed tomography, after which Collembola were extracted. Collembola species richness was lower in grazed sites, but abundances were not affected by soil compaction or vegetation height. Community composition differed between ungrazed sites with short vegetation and the other treatments, due to a greater dominance of epigeic Collembola and lower abundance of euedaphic species in this treatment. We found that the three co-occurring EEs and their interactions modify the physical environment of soil fauna, particularly through changes in soil porosity and availability of litter. This alters the relative abundance of Collembola life-forms, and thus the community composition within the soil. As Collembola are known to play a crucial role in decomposition processes, these compositional changes in litter and soil layers are expected to affect ecosystem processes and functioning.
